(1) Represents the maximum number of shares of Series A redeemable pay-in-kind

    Delaware corporation, estimated to be issuable upon the consummation of the
    merger of HB Merger LLC, a Delaware limited liability company, with and into
    Johns Manville based on the ratio of 0.02 shares of pay-in-kind preferred
    stock to each share of common stock of Johns Manville to be converted into
    pay-in-kind preferred stock.

(2) Reflects the market price of Johns Manville common stock to be exchanged for
    the pay-in-kind preferred stock in connection with the merger, computed in
    accordance with Rule 457(c) and Rule 457(f) under the Securities Act of
    1933, as amended, based upon the average of the high and low sales price of
    Johns Manville common stock as reported by the New York Stock Exchange on
    July 25, 2000, less the cash to be received in the merger ($13.00-$13.625).
    As a result of the Rule 457(f) calculation, there is no registration fee
    with respect to the securities being registered. The proposed maximum
    aggregate offering price is estimated solely to determine the registration
    fee.

                                MERGER PROPOSED

The Board of Directors of Johns Manville Corporation has approved a merger
agreement which provides for the proposed merger of Johns Manville with HB
Merger LLC, a limited liability company newly-formed by Hicks, Muse, Tate &
Furst Incorporated and Bear Stearns Merchant Fund Corp. Johns Manville will
continue as the surviving corporation in the merger.

If the merger is completed, each outstanding share of Johns Manville common
stock, other than some shares of common stock to be converted into shares of
common stock of the surviving corporation by the Manville Personal Injury
Settlement Trust and some members of Johns Manville management, and other than
shares of common stock owned by stockholders who perfect dissenters' appraisal
rights, will be converted into the right to receive $13.625 in cash and 0.02 of
a share of a 13% pay-in-kind preferred stock having a liquidation preference of
$100.00 per full share. As a result of the proposed merger, affiliates of Hicks,
Muse and Bear Stearns, the Manville Trust and some members of our management
will own all of the outstanding common stock of Johns Manville as the surviving
corporation in the merger.

Immediately following the merger, the only equity interest in the surviving
corporation held by anyone other than Hicks, Muse and its affiliates, Bear
Stearns and its affiliates, the Manville Trust and some members of our
management will be through ownership of the pay-in-kind preferred stock.

We are asking our stockholders to vote at a special meeting of stockholders to
adopt the merger agreement, to approve the transactions contemplated thereby,
including the merger, and to approve an amendment to our restated certificate of
incorporation. This stockholder approval is necessary to complete the merger.
You should note, however, that the Manville Trust has agreed to vote, subject to
some conditions, all of the approximately 76.3% of the outstanding shares of
common stock that it holds in favor of adoption of the merger agreement and
approval of the amendment to the restated certificate of incorporation. If the
Manville Trust votes its shares of Johns Manville common stock in this matter,
it would ensure adoption of the merger agreement and approval of the amendment.

This proxy statement/prospectus explains the proposed merger and the proposal to
amend our restated certificate of incorporation, as well as other information
concerning Johns Manville, the proposed transactions and the stockholders
meeting. Please read it carefully and in its entirety.

Whether or not you plan to attend the stockholders meeting, we ask you to
complete, sign and promptly return the enclosed proxy card to assure that your
shares will be voted at the meeting. This will not prevent you from voting your
shares in person if you later choose to attend. Shortly after the merger, you
will receive instructions for surrendering your shares of Johns Manville common
stock and obtaining the merger consideration. You should not submit your share
certificates for surrender until you have received these instructions.

The stockholders meeting will be held at           a.m. on             , 2000,
at our headquarters, 717 17th Street, Denver, Colorado. Formal notice of the
stockholders meeting is set forth on the next page.

On behalf of the Board of Directors, I thank you for your support.

Charles L. Henry
Chairman of the Board,
President and Chief Executive Officer

                     QUESTIONS AND ANSWERS ABOUT THE MERGER

Q:   WHAT IS THE TRANSACTION PROPOSED?

A:   This proxy statement/prospectus relates to the proposed recapitalization of
     Johns Manville through a merger. In the merger, HB Merger LLC will merge
     with and into Johns Manville, with Johns Manville as the surviving
     corporation in the merger. HB Merger LLC is an entity newly formed by
     Hicks, Muse, Tate & Furst Incorporated and Bear Stearns Merchant Fund Corp.
     We are also proposing to amend our restated certificate of incorporation.

Q:   WHAT EFFECT WILL THE MERGER HAVE ON JOHNS MANVILLE?

A:   As a result of the merger, each share of Johns Manville common stock (other
     than shares of common stock owned by stockholders who perfect dissenters'
     appraisal rights) will be converted into the right to receive the merger
     consideration described below. Prior to the merger, the Manville Trust and
     some members of our management will exchange a portion of their shares of
     Johns Manville common stock for shares of a new class TM preferred stock.
     In the merger these shares will be converted into shares of surviving
     corporation common stock and surviving corporation junior preferred stock.
     As a result, immediately following consummation of the merger, all of the
     common stock of Johns Manville will be owned by Hicks, Muse and its
     affiliates, Bear Stearns and its affiliates, the Manville Trust and some
     members of our management.

Q:   WHAT WILL I RECEIVE IN THE MERGER?

A:   If the merger is completed, you will receive for each share of Johns
     Manville common stock you own at the time of merger, $13.625 in cash and
     0.02 of a share of a 13% pay-in-kind preferred stock of the surviving
     corporation with a liquidation preference of $100.00 per full share.

Q:   WHAT ARE THE SIGNIFICANT TERMS OF THE PAY-IN-KIND PREFERRED STOCK TO BE
     RECEIVED IN THE MERGER?

A:   Each share of pay-in-kind preferred stock will have a liquidation
     preference of $100.00 per full share. Dividends will accumulate at an
     annual rate of 13% of the liquidation preference, compounded semi-
     annually. At the discretion of the surviving corporation, before the
     seventh anniversary of the effective time of the merger, dividends may be
     paid with additional shares of pay-in-kind preferred stock rather than
     cash. In addition, and subject to restrictions in the financing agreements
     to be entered into in connection with the merger, at any time the surviving
     corporation may redeem the shares of pay-in-kind preferred stock then
     outstanding at a price equal to the liquidation preference plus accumulated
     and unpaid dividends, although optional redemption by Johns Manville prior
     to the fifth anniversary of issuance will require the surviving corporation
     to pay you a premium. The surviving corporation is obligated to redeem all
     of the outstanding shares of pay-in-kind preferred stock on the twelfth
     anniversary of the date of the merger at the liquidation preference plus
     accumulated and unpaid dividends, subject to the legal availability of
     funds. The holders of pay-in-kind preferred stock generally will not have
     voting rights.

Q:   WILL ANY FRACTIONAL SHARES OF THE PAY-IN-KIND PREFERRED STOCK BE ISSUED IN
     THE MERGER?

A:   Fractional shares of pay-in-kind preferred stock will not be issued to you
     in the merger. Instead, you will receive cash in lieu of any fraction of a
     share of pay-in-kind preferred stock you would otherwise have received. For
     example, if you own 100 shares of Johns Manville common stock at the
     effective time of the merger you would receive, in addition to a cash
     payment of $1,362.50, two shares of pay-in-kind preferred stock. If you own
     101 shares of Johns Manville common stock, you would receive, in addition
     to a cash payment of $1,376.13, two shares of pay-in-kind preferred stock
     plus an additional $2.00 in cash in lieu of the 0.02 of a share pay-in-kind
     preferred stock that would otherwise be issuable to you.

                                        i
<PAGE>   5

Q:   WHAT IS THE PURPOSE OF THE PROPOSED AMENDMENT TO THE RESTATED CERTIFICATE
     OF INCORPORATION?

A:   The proposed amendment to our restated certificate of incorporation
     authorizes the issuance of up to 5,000,000 shares of preferred stock of
     Johns Manville, and establishes the terms of the class TM preferred stock.
     In the merger, these class TM preferred shares held by some members of
     management and the Manville Trust will be converted into shares of common
     stock and junior convertible preferred stock of the surviving corporation,
     rather than being converted into the cash and pay-in-kind preferred stock
     to be paid to our other stockholders.

Q:   WHAT IS THE BOARD'S RECOMMENDATION?

A:   Our board of directors recommends that you vote "FOR" approval of the
     proposed amendment to the restated certificate of incorporation and "FOR"
     adoption of the merger agreement and the approval of the transactions
     contemplated thereby, including the merger.

Q:   WHAT VOTE OF STOCKHOLDERS IS REQUIRED?

A:   Approval of the proposed amendment to our restated certificate of
     incorporation and adoption of the proposed merger agreement and the
     transactions contemplated thereby, must each be approved by the affirmative
     vote of the holders of a majority of the outstanding shares of Johns
     Manville common stock. The Manville Trust, which owns approximately 76.3%
     of the outstanding Johns Manville common stock, has agreed, subject to some
     conditions, to vote in favor of approval of the proposed amendment to our
     restated certificate of incorporation and adoption of the merger agreement.
     Assuming that the Manville Trust votes its shares as described in the
     previous sentence, approval of the proposed amendment, adoption of the
     merger agreement and the transactions contemplated thereby, would be
     ensured.

Q:   WHEN AND WHERE IS THE SPECIAL MEETING?

A:   The special meeting of stockholders will be held at      a.m. on
               , 2000 at our headquarters, 717 17th Street, Denver, Colorado.

Q:   WHAT DO I NEED TO DO NOW?

A:   You should complete, date and sign your proxy card and mail it in the
     enclosed return envelope as soon as possible so that your shares may be
     represented at the stockholders meeting, even if you plan to attend the
     meeting in person.

Q:   MAY I CHANGE MY VOTE AFTER I HAVE MAILED MY SIGNED PROXY CARD?

A:   Yes. You may change your vote by sending in a later dated, signed proxy
     card or a written revocation before the stockholders meeting or by
     attending the meeting and voting in person. Your attendance at the meeting
     will not, by itself, revoke your proxy. If you have instructed a broker to
     vote your shares, you must follow the directions received from your broker
     to change those instructions.

Q:   SHOULD I SEND MY STOCK CERTIFICATES NOW?

A:   No. If the merger is completed, you will be sent written instructions for
     surrendering your stock certificates and receiving the merger
     consideration.

Q:   WHAT HAPPENS IF I DO NOT SEND IN MY PROXY OR IF I ABSTAIN FROM VOTING?

A:   If you do not send in your proxy or do not instruct your broker to vote
     your shares or if you abstain from voting, it will have the same effect as
     a vote against approval of the proposed amendment and adoption of the
     merger agreement.

Q:   WHAT ARE THE TAX CONSEQUENCES OF THE MERGER?

A:   The merger will be a taxable transaction to you for federal income tax
     purposes. In addition, the receipt of pay-in-kind dividends on the
     preferred stock should also be taxable to you for federal income tax
     purposes. A brief summary of the expected tax consequences appears on pages
     59-63 of this proxy statement/prospectus. You should consult your tax
     advisor as to your particular circumstances.

<PAGE>   6

Q:   WHAT RIGHTS DO I HAVE TO DISSENT FROM THE MERGER?

A:   If you wish, you may dissent from the merger and seek an appraisal of the
     "fair value" of your shares, but only if you comply with all requirements
     of Delaware law, which are summarized on pages 63-64 of this proxy
     statement/prospectus. The appraised fair value of your shares may be more
     or less than the amount paid in the merger.

Q:   WHO CAN HELP ANSWER MY QUESTIONS?

A:   If you have additional questions about the merger or would like additional
     copies of the proxy statement/ prospectus, you should call MacKenzie
     Partners, Inc. at (800) 322-2885 (toll-free) or (212) 929-5500 (collect).

STOCKHOLDERS MEETING (SEE PAGE 23)

     The special meeting of Johns Manville stockholders is being held to vote
on:

     - approval of an amendment to Johns Manville's restated certificate of
       incorporation which would authorize 5,000,000 shares of preferred stock
       and create a new class TM preferred stock; and

     - adoption of the merger agreement and approval of the transactions
       contemplated thereby, including the merger.

     Approval of each of these items is a condition to completion of the merger.

RECOMMENDATION OF THE JOHNS MANVILLE BOARD (SEE PAGE 31)

     The Johns Manville board of directors recommends that you vote in favor of
the (1) approval of the amendment to the restated certificate of incorporation
and (2) adoption of the merger agreement and approval of the transactions
contemplated thereby, including the merger.

AMENDMENT TO THE RESTATED CERTIFICATE OF INCORPORATION (SEE PAGE 25)

     The merger agreement contemplates that the Manville Trust and some members
of Johns Manville management will retain a common stock interest in the
surviving corporation following the merger. In order to achieve this
continuation of interest, immediately prior to the closing of the merger, a
portion of the shares of Johns Manville common stock held by the Manville Trust
and some members of Johns Manville management will be exchanged for shares of
class TM preferred stock. In the merger, the shares of class TM preferred stock
will not be converted into the cash and pay-in-kind preferred stock merger
consideration that will be received by holders of common stock. Instead, shares
of class TM preferred stock will be converted into shares of common stock and
junior preferred stock of the surviving corporation.

     The restated certificate of incorporation of Johns Manville does not
currently authorize shares of class TM preferred stock. Therefore, it is
necessary to amend the restated certificate of incorporation to authorize the
class TM preferred stock.

THE CLASS TM PREFERRED STOCK (SEE PAGE 84)

     The proposed amendment to Johns Manville's restated certificate of
incorporation will authorize 5,000,000 shares of class TM preferred stock. In
general, each share of class TM preferred stock will have the same voting and
dividend rights as a share of Johns Manville common stock.

     The exchange of shares of Johns Manville common stock for shares of class
TM preferred stock prior to the closing of the merger will occur pursuant to an
exchange agreement between Johns Manville, the Manville Trust and some members
of Johns Manville management.

THE MERGER

     At the effective time of the merger, HB Merger LLC will merge with and into
Johns Manville, HB Merger LLC will cease to exist as a separate entity and Johns
Manville will continue as the surviving corporation in the merger. The merger
agreement is attached as Appendix A to this proxy statement/ prospectus. We
encourage you to read the merger agreement carefully and in its entirety as it
is the legal document that governs the merger.

WHAT JOHNS MANVILLE STOCKHOLDERS WILL RECEIVE IN THE MERGER

     As a result of the merger, Johns Manville common stockholders will receive,
for each share of Johns Manville common stock owned at the time of the merger,
$13.625 in cash and 0.02 of a share of a 13% pay-in-kind preferred stock of the
surviving corporation having a liquidation preference of $100.00 per full share.
                                        2
<PAGE>   12

     For example, if you own 1,000 shares of Johns Manville common stock at the
effective time of the merger, you will receive as a result of the merger $13,625
in cash and 20 shares of pay-in-kind preferred stock.

     Prior to the merger, the Manville Trust and some members of Johns Manville
management will convert a portion of their currently outstanding Johns Manville
common stock into shares of class TM preferred stock. In the merger, these class
TM preferred shares will be converted into shares of common stock and junior
preferred stock of the surviving corporation, rather than being converted into
the cash and pay-in-kind preferred stock to be paid to other Johns Manville
stockholders.

     Fractional shares of pay-in-kind preferred stock will not be issued to you
in the merger. Instead, you will receive cash in lieu of any fractional share of
pay-in-kind preferred stock you would otherwise receive.

TERMS OF THE PAY-IN-KIND PREFERRED STOCK (SEE PAGE 86)

Issuer:                      Johns Manville as the surviving corporation in the

                             - 106.5% during year one;

                             unpaid dividends, subject to the existence of funds
                             legally available for redemption.

Change in Control
Redemption:                  If following a change-in-control of the surviving
                             corporation the holders of a majority of the
                             outstanding shares so vote, the surviving
                             corporation will be obligated to redeem the
                             outstanding shares at a redemption price of 101% of
                             liquidation preference per share, plus

<PAGE>   13

                             accrued and unpaid dividends, subject to the
                             existence of funds legally available for
                             redemption.

Covenants and Restrictions:  So long as any shares of pay-in-kind preferred
                             stock remain outstanding, subject to some important
                             qualifications and exceptions, the terms of the
                             pay-in-kind preferred stock limit, among other
                             things, without the approval of the holders of a
                             majority of the outstanding shares of pay-in-kind
                             preferred stock, the amendment of the surviving
                             corporation's certificate of incorporation so as to
                             adversely affect the specified rights of the
                             pay-in-kind preferred stock, the creation,
                             authorization or issuance of capital stock senior

                             transactions involving affiliates and subsidiaries

                             certain capital stock on parity with the
                             pay-in-kind preferred stock, the issuance of any
                             capital stock with a scheduled redemption date

                             the payment of dividends on, and redemption of,
                             securities junior to or on parity with the
                             pay-in-kind preferred stock.

Voting:                      Non-voting, except as required by law or as
                             described below. Holders of shares of pay-in-kind
                             preferred stock may elect two directors if:

                             - three semi-annual dividends are not paid;

                             - certain bankruptcy filings are made and not

                             The number of directors will be reduced to one if
                             the liquidation preference of the outstanding

                             event date is reduced by 50% or more.

                             affect the specified rights of the pay-in-kind
                             preferred stock without the approval of the holders
                             of a majority of the outstanding shares of

       Southern District of New York approving the merger, the Manville Trust's
       voting agreement, the tax matters agreement entered into between the

     In addition, HB Merger LLC's obligation to complete the merger is also

     - receipt of the financing required to complete the merger;

     - the continued employment by Johns Manville of Charles L. Henry, its
       President and Chief Executive Officer;

     - the absence of any event having a material adverse effect on Johns
       Manville since the date of the merger agreement;

     - the tax agreement between Johns Manville and Manville Trust being in
       effect; and

     - the absence of a public announcement by the Securities and Exchange
       Commission as to any revision or intended revision of current published
       interpretations concerning recapitalization accounting that would
       preclude application of recapitalization accounting to the merger.

TERMINATION OF THE MERGER AGREEMENT (SEE PAGE 72)

     The merger agreement may be terminated, including after stockholder
approval, by mutual consent or, if the following factors are present, by either
party, so long as the terminating party's failure to perform its obligations was
not the cause of the merger not being completed if:

     - the merger is not consummated by November 30, 2000; however, this date
       will be extended to December 28, 2000 if the stockholders meeting has not
       been held on or before November 1, 2000 and will be further extended to
       January 31, 2001 if the stockholders meeting has not been held on or
       prior to December 1, 2000;
                                        5
<PAGE>   15

     - the required stockholder approval is not obtained;

     - the merger is permanently prohibited by an injunction, order or law;

     - the other party is in material breach of its obligations under the merger
       agreement, and that breach is incurable, or if capable of being cured, is
       not cured within 30 days following notice of breach by the other party;
       or

     - the voting agreement between the Manville Trust and HB Merger LLC is
       terminated.

     The merger agreement can also be terminated by Johns Manville to enter into
a superior proposal with a party other than HB Merger LLC.

     The merger agreement can also be terminated by HB Merger LLC if:

     - Johns Manville's board withdraws or adversely modifies its recommendation
       of the merger and the Manville Trust terminates the voting agreement;

     - Johns Manville enters into a written agreement with a third party for a
       superior proposal;

     - Johns Manville negotiates with a third party regarding a superior
       proposal for a period in excess of 45 days; or

     - the stockholders meeting has not been held by January 15, 2001.

TERMINATION FEES (SEE PAGE 73)

     Johns Manville must pay to HB Merger LLC and HB Finance LLC a termination
fee of $53,000,000 plus reimbursement for out-of-pocket expenses of up to
$12,500,000 if:

     - Johns Manville terminates the merger agreement to enter into a superior
       proposal or HB Merger LLC terminates the merger agreement because Johns
       Manville has entered into a superior proposal; or

     - the merger agreement is terminated because the voting agreement between
       the Manville Trust and HB Merger LLC has been terminated due to the Johns
       Manville board withdrawing its recommendation of the merger or due to the
       Manville Trust entering into a superior proposal with respect to its
       shares of Johns Manville common stock.

     Johns Manville will be required to pay the expenses referred to above at
the time of termination, and subsequently pay the termination fee upon execution
of an agreement with respect to, or consummation of, another acquisition
proposal within one year following termination of the merger agreement if:

     - HB Merger LLC terminates the merger agreement due to Johns Manville's
       continuing to negotiate with a third party regarding a superior proposal
       for a period of more than 45 days;

     - HB Merger LLC terminates the merger agreement due to the stockholders
       meeting not being held by January 15, 2001;

     - the merger agreement is terminated due to the order of the U.S.
       bankruptcy court not being obtained, but only if the acquisition proposal
       entered into or consummated within one year is either (1) with a person
       who had made an acquisition proposal at the time of the court hearing or
       (2) the consideration being paid is equal to or greater than the
       consideration to be paid in the merger;

     - HB Merger LLC terminates the merger agreement due to Johns Manville's
       wilful breach of a representation or covenant that results in the
       relevant closing condition not being satisfied; or

     - the merger agreement is terminated due to the failure to obtain
       stockholder approval.

                                        6
<PAGE>   16

     In addition, Johns Manville will be required to reimburse the expenses
referred to above if HB Merger LLC terminates the merger agreement due to a
non-wilful breach of a covenant by Johns Manville which results in the relevant
closing condition not being satisfied.

     Johns Manville and the Manville Trust have agreed that in some
circumstances the Manville Trust will reimburse Johns Manville for the
termination fee and expenses required to be paid. Following some types of
transactions, Johns Manville may be required to repay the reimbursed amount to
the Manville Trust.

VOTING AGREEMENT (SEE PAGE 74)

     In connection with the execution of the merger agreement, HB Merger LLC
entered into a voting agreement with the Manville Trust. In the voting
agreement, the Manville Trust agreed to vote all of its shares of Johns Manville
common stock as follows:

     - in favor of the adoption of the merger agreement and approval of the
       amendment to the restated certificate of incorporation;

     - against any proposal to the stockholders of Johns Manville which would
       prevent the consummation of the merger; and

     - against any acquisition proposal other than the merger.

     The Manville Trust's voting obligation only arises upon issuance of the
U.S. bankruptcy court order approving the merger and the transactions in
connection with the merger.

     The Manville Trust also agreed not to sell or pledge its shares of Johns
Manville common stock, or grant any proxies or powers of attorney with respect
to those shares, prior to the completion of the merger or the termination of the
voting agreement. The Manville Trust may terminate the voting agreement if the
Johns Manville board modifies or withdraws its recommendation of the merger
agreement, if the U.S. bankruptcy court fails to issue the required order, or in
some circumstances where the Manville Trust receives a superior proposal for the
purchase of its shares of Johns Manville common stock.

TAX AGREEMENT (SEE PAGE 75)

     Johns Manville is statutorily liable for all federal income taxes of the
designated settlement fund portion of the Manville Trust, and is contractually
liable, under an agreement with the Manville Trust known as the supplemental
agreement, for other income taxes of the Manville Trust. In connection with the
merger, Johns Manville and the Manville Trust entered into the tax agreement to
settle Johns Manville's liability for taxes of the Manville Trust. The tax
agreement provides that upon satisfaction of its conditions, including
consummation of the merger, Johns Manville will pay $90,000,000 in cash to the
Manville Trust. In return, the Manville Trust will eliminate Johns Manville's
contractual liability for income taxes of the Manville Trust and indemnify Johns
Manville and its successors for all income taxes of the Manville Trust, and
related costs, expenses, losses, penalties and damages arising from the tax
liabilities which Johns Manville may have owed. All or a portion of the proceeds
paid to the Manville Trust will be placed in escrow to underlie the Manville
Trust's indemnification obligations. In addition, in connection with the tax
agreement, Johns Manville and the Manville Trust agreed to amend the trust
agreement under which the Manville Trust is organized and the supplemental
agreement between Johns Manville and the Manville Trust.

EXCHANGE AGREEMENT (SEE PAGE 77)

     Johns Manville, the Manville Trust and some members of the management of
Johns Manville have entered into an exchange agreement under which 3,200,000
million shares of Johns Manville common stock held by the Manville Trust and a
portion of the shares held by members of the management will be converted into
class TM preferred stock immediately prior to the closing under the merger
agreement. The merger agreement provides that at the effective time of the
merger, each share of class TM preferred stock
                                        7
<PAGE>   17

will be automatically converted into 0.6 of a share of the surviving
corporation's common stock and 0.4 of a share of the surviving corporation's
junior preferred stock.

RISK FACTORS (SEE PAGE 19)

     In determining whether to vote to approve the proposed amendment to the
restated certificate of incorporation and adopt the merger agreement, you should
consider carefully the risk factors described in this proxy
statement/prospectus, including the risks that:

     - there may not be a trading market for the pay-in-kind preferred stock;

     - the pay-in-kind preferred stock will generally have no voting rights;

     - there is no assurance of receiving cash dividends when due on the
       pay-in-kind preferred stock;

     - holders of pay-in-kind preferred stock may be liable for taxes in respect
       of the pay-in-kind preferred stock and the dividends thereon without
       having received any cash;

     - Johns Manville may be unable to pay the liquidation preference and
       accrued dividends on the pay-in-kind preferred stock at the redemption
       price on any scheduled redemption date;

     - Johns Manville's substantial debt level and stockholders' deficit
       following the merger could adversely affect its operations and its
       ability to service such debt, pay dividends and make scheduled
       redemption;

     - the terms of the financing for the merger are expected to restrict Johns
       Manville's ability to pay cash dividends on the pay-in-kind preferred
       stock; and

     - in some circumstances, payments made in connection with the merger could
       be challenged under fraudulent conveyance or similar laws.

APPRAISAL RIGHTS (SEE PAGE 63)

     Under Delaware law, holders of Johns Manville common stock have the right
to demand and to receive, instead of the consideration being offered in the
merger, an amount which the Delaware Court of Chancery decides is the fair value
of those shares of Johns Manville common stock or to which the parties agree.
This amount may be more or less than the value of what such stockholders would
otherwise receive in the merger. Stockholders wishing to exercise appraisal
rights must not vote in favor of adoption of the merger agreement and must take
the steps described in the section entitled "Appraisal Rights" and in Appendix
F.

OPINIONS OF JOHNS MANVILLE FINANCIAL ADVISOR (SEE PAGE 34)

     In deciding to approve the merger, the Johns Manville board considered the
opinion of its financial advisor, J.P. Morgan Securities Inc. to the effect
that, as of the date of the opinion, the per share consideration of $13.625 in
cash and 0.02 of a share of pay-in-kind preferred stock to be received by
holders of Johns Manville common stock in the merger was fair, from a financial
point of view, to those stockholders. This opinion is attached as Appendix C and
we encourage you to read it carefully and in its entirety.

     In deciding to approve the tax agreement, the Johns Manville board
considered the opinion of J.P. Morgan Securities Inc. to the effect that the
$90,000,000 consideration to be paid to the Manville Trust pursuant to the tax
agreement was fair, from a financial point of view, to the holders of Johns
Manville common stock other than the Manville Trust for the settlement of those
tax liabilities. This opinion is attached as Appendix D, and we encourage you to
read it carefully and in its entirety.

OPINION OF THE MANVILLE TRUST FINANCIAL ADVISOR (SEE PAGE 40)

     The Manville Trust, in connection with its consideration of the proposed
merger, considered the opinion of Goldman, Sachs & Co. to the effect that, as of
the date of the opinion and based upon and subject to the qualifications and
assumptions described in the opinion, the consideration to be received by the
Manville Trust in exchange for its shares of Johns Manville common stock
pursuant to the exchange agreement and the merger agreement was fair, from a
financial point of view to the Manville Trust. This opinion is attached as
Appendix E.

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

(A)  During 1996 Johns Manville recorded nonrecurring charges totaling $49.2
     million. These charges included $41.7 million for the shutdown of current
     operations, demolition of facilities and site restoration, and $7.5 million
     of asset write-downs to estimated fair values, partially offset by a gain
     on the sale of other manufacturing assets.

(B)  In 1996 Johns Manville disposed of its 81.3 percent interest in Riverwood
     International Corporation. Accordingly, Riverwood's operations have been
     reflected as discontinued operations and its operating results have been
     excluded from the determination of income from continuing operations for
     all periods presented. Income from continuing operations, net of tax,
     includes gains on sales of equity investments, interest income, interest
     expense and profit sharing expense.

     Income before extraordinary items and cumulative effect of accounting
     change and net income include a gain on disposal of discontinued operations
     of $216.2 million, net of tax, in 1996, a loss on disposal of discontinued
     operations of $42.5 million, net of tax, in 1995, and income from
     discontinued operations of $36.5 million in 1995, net of tax.

     During 1997 Johns Manville recognized an additional net gain on disposal of
     discontinued operations of Riverwood of $19.5 million, of which $8.2
     million related to income taxes.

(C)  Total assets at December 31, 1998 include the acquisition deposit of $227.3
     million for the January 1, 1999 acquisition of certain
     spunbond/monofilament assets.

     The $375.6 million net assets and liabilities of the discontinued
     operations of Riverwood were classified as net assets held for sale at
     December 31, 1995.

(D)  In 1996 Johns Manville recorded an extraordinary loss of $314.3 million,
     net of taxes of $169.2 million, on the exchange of approximately 32.5
     million shares of Johns Manville's common stock for the termination of the
     Manville Trust's profit sharing right to 20 percent of Johns Manville's net
     earnings (as adjusted).

(E)  Johns Manville recorded extraordinary losses on early extinguishments of
     debt, net of taxes, of $5.8 million, $31.8 million and $2 million in 1999,
     1998 and 1996, respectively.

(F)  Effective January 1, 1998 Johns Manville changed its method of accounting
     for glass furnace rebuild costs. The cumulative effect of this change in
     accounting principle increased 1998 earnings by $27.4 million, net of taxes
     of $17.9 million.

(G)  Johns Manville sold its 5 percent net smelter royalty on certain metals
     produced by the Stillwater Mining Company for cash resulting in other
     income of $36 million in 1998.

(H)  During 1996 Johns Manville redeemed its Cumulative Preference Stock, Series
     B. Earnings per share amounts prior to 1997 were calculated after the
     deduction for preference stock dividends/accretion and the $52.1 million
     premium on preference stock redemption.

(I)  Calculated by dividing (i) income before income taxes and income or loss
     from equity investees plus fixed charges by (ii) fixed charges, which
     consist of interest expense, capitalized interest, one-third of rent
     expense (which is representative of the interest component), and adjusted
     preferred dividends.

UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL DATA

     The following unaudited pro forma condensed consolidated financial
statements have been derived by the application of pro forma adjustments to our
historical consolidated financial statements incorporated by reference in this
proxy statement/prospectus. The unaudited pro forma condensed consolidated
statements of operations for the periods presented give effect to the merger and
the merger financing as if each had occurred on January 1, 1999 and exclude
non-recurring items directly attributable to the merger. The unaudited pro forma
condensed consolidated balance sheet gives effect to the merger and the merger
financing as if each had occurred on March 31, 2000. The adjustments are
described in the accompanying notes. The pro forma financial statements should
not be considered indicative of actual results that would have been achieved had
the merger and the merger financing been consummated on the dates indicated, nor
are they necessarily indicative of future operating results or financial
position. The pro forma financial statements should be read in conjunction with

           CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

     This document contains forward-looking statements with respect to the
financial condition, results of operations and business of Johns Manville. These
statements may be made directly in this document referring to Johns Manville or
may be made part of this document by reference to other documents filed with the
Securities and Exchange Commission by Johns Manville, which is known as
"incorporation by reference," and may include statements for the period
following the completion of the merger. You can find many of these statements by
looking for words such as "believes," "expects," "anticipates," "estimates,"
"projects," or similar expressions in this document or in the documents
incorporated by reference. In addition, the information in "Certain Projections
as to Future Operations" constitutes such forward-looking statement.

     These forward-looking statements are subject to numerous assumptions, risks
and uncertainties. Factors that may cause actual results to differ from those
contemplated by the forward-looking statements include, among others, the
following:

     - fluctuations in demand for Johns Manville's products generally;

     - the effect of overall capacity levels in the building products markets
       served by Johns Manville;

     - the cyclical nature of the building products industry, which is
       influenced by general economic conditions and other macroeconomic factors
       such as the general rate of inflation, interest rates, and employment
       rates that affect demand in residential and commercial, industrial and
       residential construction markets;

     - fluctuations in the cost of raw materials and energy sources used by
       Johns Manville;

     - the occupational health and safety aspects of Johns Manville's products;

     - the financial condition of Johns Manville's customers;

     - the effect of significant debt on Johns Manville's financial and
       operating flexibility;

     - expected levels of capital spending; and

     - expectations as to contingent liabilities.

     Overall capacity levels in the building products markets served by Johns
Manville directly affect prices and the need for capacity for Johns Manville's
products. Other factors that may affect prices and capacity levels include the
overall competitive environment in which Johns Manville operates and the
availability and pricing of raw materials and energy sources used by Johns
Manville.

     Because forward looking statements are subject to risks and uncertainties,
actual results may differ materially from those expressed or implied by the
forward-looking statements. You are cautioned not to place undue certainty on
the statements, which speak only as of the date of this document or the date of
any document incorporated by reference.

     All subsequent written and oral forward-looking statements attributable to
Johns Manville or any person acting on its behalf are expressly qualified in
their entirety by the cautionary statements contained or referred to in this
section. Johns Manville does not undertake and specifically declines any
obligation to release publicly any revisions to the forward looking statements
to reflect events or circumstances after the date of this document or to reflect
the occurrence of unanticipated events.

                                  RISK FACTORS

     YOU SHOULD CONSIDER THE FOLLOWING MATTERS IN DECIDING HOW TO VOTE IN
CONNECTION WITH THE APPROVAL OF THE PROPOSED AMENDMENT TO THE RESTATED
CERTIFICATE OF INCORPORATION AND ADOPTION OF THE MERGER AGREEMENT. YOU ALSO
SHOULD CONSIDER THE OTHER INFORMATION INCLUDED OR INCORPORATED BY REFERENCE IN
THIS DOCUMENT.

IT MAY BE DIFFICULT FOR YOU TO SELL YOUR PAY-IN-KIND PREFERRED STOCK

     It may be difficult for you to sell the pay-in-kind preferred stock that
you receive in the merger. The pay-in-kind preferred stock is a new issue of
securities for which there is currently no established trading market. If your
shares of pay-in-kind preferred stock are traded, they may trade at a
substantial discount from the liquidation preference. Any discount could depend
upon a number of factors, including:

     - dividend and interest rates generally prevailing in the financial
       markets;

     - the market demand for the pay-in-kind preferred stock;

     - the market for similar securities generally;

     - general economic conditions;

     - terms of the pay-in-kind preferred stock; and

     - the financial condition and performance of the surviving corporation.

     Johns Manville cannot assure you that a trading market for the pay-in-kind
preferred stock will develop. The absence of a trading market would adversely
affect the liquidity of your shares of pay-in-kind preferred stock. The merger
agreement provides that HB Merger LLC will seek to have the pay-in-kind
preferred stock listed for trading on the Nasdaq National Market. If the
pay-in-kind preferred stock is not listed for trading on the Nasdaq National
Market, the surviving corporation will attempt to arrange for an established
securities dealer to make a market in the pay-in-kind preferred stock.

     The market price for the pay-in-kind preferred stock could be adversely
affected by shares available for future sale. Following the merger, the Manville
Trust may sell the shares of pay-in-kind preferred stock that it owns, subject
to applicable restrictions under federal securities laws and the restriction on
selling those shares without the consent of Bear Stearns Corporate Lending for
the 180-day period following the merger. Johns Manville does not know what
effect future sales of pay-in-kind preferred stock or the availability of shares
for future sales will have on the market price for shares of pay-in-kind
preferred stock prevailing from time to time. However, sales of a substantial
amount of pay-in-kind preferred stock on the public market, or the perception
that those sales could occur, could adversely affect market prices for the
pay-in-kind preferred stock.

THE PAY-IN-KIND PREFERRED STOCK WILL GENERALLY HAVE NO VOTING RIGHTS

     As a holder of the pay-in-kind preferred stock you will generally not have
any voting rights in connection with the election of directors or otherwise. You
will have the right to a class vote on certain matters as required by Delaware
law, and will have the right to elect up to two directors in the circumstances
set forth below:

     - if three dividends on the pay-in-kind preferred stock have not been paid;

     - if any bankruptcy or insolvency or similar proceeding is commenced by or
       against the surviving corporation (if an involuntary proceeding, if such
       proceeding remains undismissed or unstayed for sixty days);

     - if for any reason the surviving corporation has failed to redeem the
       pay-in-kind preferred stock on the scheduled redemption date or in
       connection with any redemption required following a change in control; or

                                       19
<PAGE>   29

     - if the surviving corporation fails to comply (and non-compliance
       continues for a period of thirty days) in any material respect with any
       of the covenants of the terms of the pay-in-kind preferred stock.

     In addition, after the merger you will have the right to a class vote on
any amendment to the surviving corporation's certificate of incorporation or
bylaws that adversely affect the terms of the pay-in-kind preferred stock and on
certain matters other than the election of directors.

     Immediately following the merger the Manville Trust will own approximately
     shares of pay-in-kind preferred stock, representing approximately      % of
the outstanding shares. This ownership interest will enable the Manville Trust
to cause the election of any directors which the holders of pay-in-kind
preferred stock may become entitled to elect. With this ownership interest, the
Manville Trust will also be able to, without the action of any other holders of
pay-in-kind preferred stock, approve amendments to the terms of the pay-in-kind
preferred stock and consent to actions such as some stock issuances, dividends
and other payments by the surviving corporation that are only permitted to be
undertaken by the surviving corporation with the consent of the holders of a
majority of the outstanding shares of pay-in-kind preferred stock. However,
without the consent of each affected holder of the pay-in-kind preferred stock,
the surviving corporation cannot amend its certificate of incorporation to
reduce the dividend payable on, or the liquidation preference of, the
pay-in-kind preferred stock.

THERE IS NO ASSURANCE THAT YOU WILL BE PAID CASH DIVIDENDS WHEN DUE ON THE
PAY-IN-KIND PREFERRED STOCK

     There is no guarantee that the surviving corporation will ever pay cash
dividends on the pay-in-kind preferred stock. Cash dividends may only be paid on
the pay-in-kind preferred stock if there are funds legally available to pay
dividends. In addition, the terms of the financing in connection with the merger
are expected to restrict the surviving corporation's ability to pay cash
dividends on the pay-in-kind preferred stock.

THE SURVIVING CORPORATION MAY NOT BE ABLE TO PAY THE REQUIRED REDEMPTION AMOUNTS
ON THE PAY-IN-KIND PREFERRED STOCK

     There is no guarantee that the surviving corporation will be able to redeem
the pay-in-kind preferred stock when required to do so. After the merger and
related recapitalization, the surviving corporation will have a high level of
debt. The obligations of the surviving corporation to the holders of its debt
and other creditors generally will have priority over the surviving
corporation's obligations to the holders of the pay-in-kind preferred stock.
Furthermore, redemption amounts may be paid only out of funds legally available.

YOU MAY HAVE TO PAY TAXES RELATED TO THE PAY-IN-KIND PREFERRED STOCK AT TIMES
WHEN NO CASH IS DISTRIBUTED BY THE SURVIVING CORPORATION

     The fair market value of dividends paid by the surviving corporation on the
pay-in-kind preferred stock will be required to be included in income when paid
to the extent that the surviving corporation has earnings and profits as
measured for tax purposes, regardless of whether the dividends are paid in cash
or in additional shares of pay-in-kind preferred stock. In addition, in general,
to the extent the redemption price of the pay-in-kind preferred stock exceeds
the fair market value of the pay-in-kind preferred stock at the effective time
of the merger by more than a de minimis amount, that excess will be included in
the taxable income of holders on a constant yield method over the term of the
pay-in-kind preferred stock, even though no cash will be paid with respect to
these amounts prior to redemption. As a result, you may be required to pay taxes
with respect to the pay-in-kind preferred stock even though at that time you are
not receiving any cash from the surviving corporation.

                                       20
<PAGE>   30

THE SURVIVING CORPORATION'S SUBSTANTIAL DEBT LEVEL FOLLOWING THE MERGER COULD
INCREASE THE RISK OF YOUR CONTINUED INVESTMENT IN THE SURVIVING CORPORATION

     You will continue to be a stockholder after the merger as a result of your
ownership of pay-in-kind preferred stock. The operating performance of the
surviving corporation may have an effect on the value of your pay-in-kind
preferred stock. In addition, after the merger, the surviving corporation's
operations will have to generate cash to service a much greater level of debt
than exists today. If the surviving corporation cannot generate enough cash, it
may not be able to make required cash payments to you with respect to your
pay-in-kind preferred stock. Your investment in pay-in-kind preferred stock
could, as a result, diminish in value.

     As of June 30, 2000, Johns Manville had long-term indebtedness of
approximately $472 million. On a pro forma basis, after giving effect to
consummation of the merger and the debt financings, Johns Manville expects that
it would have had consolidated debt of approximately $2.2 billion as of that
date. The increased debt may:

     - reduce the surviving corporation's flexibility to respond to changing
       business and economic conditions;

     - increase vulnerability to general adverse economic and industry
       conditions, particularly due to the cyclical nature of the building
       products industry;

     - limit capital expenditures and acquisitions;

     - place the surviving corporation at a competitive disadvantage compared to
       its competitors that have less debt; and

     - limit, along with the restrictive covenants of the contemplated
       financing, the surviving corporation's ability to borrow additional
       funds.

     If the surviving corporation is unable to generate sufficient cash flow
from operations in the future to service its debt, it may have to refinance all
or a portion of its existing debt or obtain additional financing. There can be
no assurance that any refinancing of this kind would be possible or that any
additional financing could be obtained. The inability to obtain additional
financing, and the terms of any additional financing obtained, could have a
material adverse effect on the surviving corporation and on your investment in
pay-in-kind preferred stock.

     Furthermore, because the surviving corporation expects that debt incurred
to finance the merger or debt (if any) incurred to refinance merger financing
will be incurred by subsidiaries of the surviving corporation, the terms of
these financing instruments will likely restrict the ability of the subsidiaries
to make payments to the surviving corporation, which would likely impair the
surviving corporation's ability to make cash payments on pay-in-kind preferred
stock.

THE PAYMENT OF THE MERGER CONSIDERATION TO YOU COULD BE VOIDED IF A COURT FINDS
A FRAUDULENT CONVEYANCE

     The surviving corporation and its subsidiaries will incur substantial
indebtedness in connection with the merger, the proceeds of which will be used,
among other things, to pay you the $13.625 per share cash portion of the merger
consideration. The incurrence of debt by the surviving corporation or its
subsidiaries, in connection with the merger, and the payment of the merger
consideration, is subject to review under relevant federal and state bankruptcy
or fraudulent conveyance statutes in a bankruptcy, reorganization or
rehabilitation case or similar proceeding or in a lawsuit by or on behalf of
unpaid creditors of the surviving corporation. Generally if a court in a suit by
an unpaid creditor or representative of creditors of the surviving corporation
were to find that:

     - the payment of the merger consideration or the incurrence of the
       indebtedness by the surviving corporation or its subsidiaries was made
       with the intent of hindering, delaying or defrauding creditors; or that

                                       21
<PAGE>   31

     - the surviving corporation received less than reasonably equivalent value
       or fair consideration in connection with such payment or incurrence and
       the surviving corporation either:

      -- was insolvent or was rendered insolvent by the transaction,

      -- was engaged in a business or transaction for which its assets
         constituted unreasonably small capital, or

      -- intended to incur, or believed that it would incur, obligations beyond
         its ability to pay as those obligations matured;

then that court could determine that the payment of the cash portion of the
merger consideration to stockholders or the incurrence of debt violated
applicable provisions of the United States bankruptcy code and/or applicable
state fraudulent conveyance laws. If a determination of this kind were made,
there is a risk that a court could require stockholders receiving the merger
consideration to return that consideration to the surviving corporation, its
creditors or their representatives.

     The measure of insolvency will vary depending on the law of the applicable
jurisdiction. Generally, however, a company would be considered insolvent if:

     - the fair value of its assets is less than the amount required to pay its
       expected liability on debts as they become due; or

     - the sum of the company's liabilities is greater than the fair value of
       its assets.

     It is a condition to Johns Manville's obligation to consummate the merger
that the Johns Manville board receive an opinion, in form and substance
reasonably acceptable to the board, from an appraisal firm to the effect that as
of the effective time of the merger, and after giving effect to the financing,
the surviving corporation will not be insolvent, have unreasonably small capital
or have incurred or planned to incur debts beyond its ability to pay. HB Merger
LLC and HB Finance LLC have retained Corporate Valuation Advisors, Inc. to
render that opinion.

                INFORMATION CONCERNING THE STOCKHOLDERS MEETING

DATE, TIME AND PLACE

     This proxy statement/prospectus is furnished to you in connection with the
solicitation of proxies by the Johns Manville board for a special meeting of
stockholders to be held at        a.m., on           , 2000, at 717 17th Street,
Denver, Colorado, or any postponement or adjournment of the meeting.

PURPOSE OF THE STOCKHOLDERS MEETING

     At the stockholders meeting, you will be asked:

     - to consider and vote upon a proposal to approve the amendment to the
       restated certificate of incorporation;

     - to consider and vote upon a proposal to adopt the merger agreement and
       approve the transactions contemplated thereby, including the merger; and

     - to transact any other business that may properly come before the meeting
       or any adjournment or postponement of the meeting.

RECORD DATE; QUORUM; OUTSTANDING COMMON STOCK ENTITLED TO VOTE

     All record holders of shares of Johns Manville common stock at the close of
business on          , 2000 are entitled to notice of, and to vote at, the
stockholders meeting and any adjournment or postponement of the meeting. The
presence, in person or by proxy, of holders of a majority of the outstanding
shares of Johns Manville common stock is required to constitute a quorum for the
transaction of business. Abstentions and broker non-votes count as present for
establishing a quorum. A list of record holders will be available for
examination at our principal executive offices from      , 2000 until the
meeting. At the close of business on             , 2000, there were      shares
of Johns Manville common stock outstanding. Of those shares 112,730,819
(approximately 76.3%), were held by the Manville Trust.

VOTE REQUIRED

     The affirmative vote of the holders of a majority of the shares of Johns
Manville common stock issued and outstanding on the record date is required for
approval of the amendment to the restated certificate of incorporation and for
adoption of the merger agreement and approval of the transactions contemplated
thereby, including the merger. The affirmative vote of the holders of a majority
of the shares of Johns Manville common stock voting is required to permit the
proxies to adjourn the Johns Manville meeting to solicit more votes or proxies
in favor of adoption of the proposals.

     Any failure to be present at the Johns Manville meeting, in person or by
proxy, and any abstention and any broker non-vote, as explained below, will have
the same effect as a vote against approval of the amendment to the restated
certificate of incorporation and adoption of the merger agreement and approval
of the transactions contemplated thereby, including the merger. With respect to
any proposal to adjourn the meeting to solicit more votes or proxies in favor of
the proposals at the meeting, any failure to be present at the meeting, in
person or by proxy, and any abstention and any broker non-vote, will have the
effect of reducing the aggregate number of shares of Johns Manville common stock
voting and, therefore, the number of shares of Johns Manville common stock
required to permit the proxies to adjourn the meeting to solicit more votes or
proxies. Under the rules of the New York Stock Exchange, brokers who hold shares
in street name for customers will not have authority to vote on approval of the
amendment to the restated certificate of incorporation or the adoption of the
merger agreement and approval of the transactions contemplated thereby,
including the merger unless they receive specific instructions from the
beneficial owners of those shares. Shares that are not voted because brokers did
not receive any instructions are referred to as "broker non-votes." Under
Delaware law, in determining whether approval of the amendment to the restated
certificate of incorporation and adoption of the merger agreement and approval
of the transactions contemplated thereby, including the merger have received the
requisite

                                       23
<PAGE>   33

number of affirmative votes, abstentions and broker non-votes will have the same
effect as a vote against those proposals.

VOTING AND REVOCATION OF PROXIES

     A form of proxy card for your use at the stockholders meeting accompanies
this proxy statement/ prospectus. All properly executed proxies that are
received prior to or at the stockholders meeting and not revoked will be voted
at the meeting in the manner specified. If you execute and return a proxy and do
not specify otherwise, the shares represented by your proxy will be voted "FOR"
approval of the amendment to the restated certificate of incorporation and "FOR"
adoption of the merger agreement and approval of the transactions contemplated
thereby, including the merger, and in the discretion of the proxies with respect
to any other matter before the meeting. In that case, you will not have the
right to dissent from the merger and seek an appraisal of the fair value of your
shares. An executed, but blank proxy card differs from a broker non-vote. By
executing and returning a proxy card, but not choosing to vote on any matter,
you will be considered to have authorized approval of that matter, whereas a
broker non-vote will not be voted and will therefore have the same effect as a
vote against the proposals.

     If you have given a proxy pursuant to this solicitation, you may
nonetheless revoke it by attending the stockholders meeting and giving oral
notice of your intention to vote in person. In addition, you may revoke any
proxy you give at any time before the stockholders meeting by delivering to our
Secretary a written statement revoking it or by delivering an executed proxy
bearing a later date. If you have executed and delivered a proxy to us, your
attendance at the stockholders meeting will not in and of itself constitute a
revocation of your proxy.

SOLICITATION OF PROXIES

     We will bear the cost of the solicitation of proxies. We will solicit
proxies initially by mail. Further solicitation may be made by our directors,
officers and employees personally, by telephone or otherwise, but they will not
be specifically compensated for these services. Upon request, we will reimburse
brokers, dealers, banks or similar entities acting as nominees for their
reasonable expenses incurred in forwarding copies of the proxy materials to the
beneficial owners of the shares of common stock they hold of record. We have
retained MacKenzie Partners, Inc. to coordinate the solicitation of proxies for
a fee of $7,500, plus reasonable out-of-pocket expenses.

OTHER MATTERS

     We do not know of any matters other than those described in this proxy
statement/prospectus which may come before the stockholders meeting. If any
other matters are properly presented to the stockholders meeting for action, we
intend that the persons named in the enclosed form of proxy card will vote in
accordance with their best judgment. These matters may include an adjournment or
postponement of the stockholders meeting. If any adjournment or postponement is
made, we may solicit additional proxies during the adjournment period.

     Please return your marked proxy card promptly so your shares can be
represented, even if you plan to attend the stockholders meeting in person. You
should not send any certificates representing common stock with your proxy card.

             AMENDMENT TO THE RESTATED CERTIFICATE OF INCORPORATION

     Approval of the amendment to the restated certificate of incorporation is a
condition to the consummation of the merger. The proposed amendment must be
approved by the affirmative vote of the holders of a majority of the outstanding
shares of Johns Manville common stock. A form of the certificate of amendment
giving effect to the proposed amendment is included as Appendix B to this proxy
statement/prospectus.

     If the amendment to the restated certificate of incorporation is approved
and the merger agreement is adopted, prior to the closing we will file with the
Delaware Secretary of State a certificate of amendment to the restated
certificate of incorporation, substantially in the form attached as Appendix B.
Upon that filing, Article Fourth of the restated certificate of incorporation
will be amended to authorize, designate the rights, preferences, privileges
restrictions and other matters of 5,000,000 shares of class TM preferred stock.
The Johns Manville board believes that it is advisable to amend Article Fourth
of the Johns Manville restated certificate of incorporation revising the total
number of authorized shares of preferred stock to 5,000,000 and designating the
rights, preferences, privileges restrictions and other matters of the 5,000,000
shares of preferred stock as class TM preferred stock with a par value of $0.01
per share. The amendment may be withdrawn by Johns Manville at any time prior to
the filing of a certificate of amendment with the Delaware Secretary of State,
even if approval for the amendment has been obtained at the stockholders
meeting.

     We are proposing the amendment to the restated certificate of incorporation
in order to permit the issuance of Johns Manville class TM preferred stock as
required under the merger agreement and the exchange agreement. At the effective
time of the merger, the class TM preferred stock will be converted into 0.6 of a
share of surviving corporation common stock and 0.4 of a share of surviving
corporation junior preferred stock. For more information regarding the exchange
of class TM preferred stock, see "The Merger Agreement -- Exchange of Shares".

                             THE MERGER TRANSACTION

BACKGROUND OF THE MERGER

     Johns Manville's board of directors, as part of its ongoing oversight and
planning, has from time to time considered various financial and other
alternatives that might be available to increase the value of Johns Manville's
common stock to all of its stockholders. At several meetings of the Johns
Manville board held in the second half of 1998, at the request of the Johns
Manville board, J.P. Morgan, Johns Manville's financial advisor, reviewed with
the Johns Manville board alternatives for consideration. Alternatives reviewed
included, among other things, continuing to operate Johns Manville as an
independent public company under its current corporate and capital structure,
Johns Manville purchasing all or a portion of the shares of Johns Manville
common stock held by the Manville Trust, offerings of Johns Manville stock on a
primary basis by Johns Manville or on a secondary basis by the Manville Trust,
potential acquisition transactions and the sale or merger of Johns Manville.

     In the context of review of these alternatives, the Johns Manville board
considered Johns Manville's statutory liability for federal income taxes imposed
on the designated settlement fund portion of the Manville Trust, and its
contractual liability to the Manville Trust for other income taxes. As a result,
J.P. Morgan and Goldman Sachs, financial advisor to the Manville Trust, were
asked to consider the impact that Johns Manville's liability for taxes of the
Manville Trust might have on various alternative transactions. J.P. Morgan and
Goldman Sachs concluded that some of these transactions would be unlikely to be
successfully concluded if Johns Manville and the Manville Trust could not agree
on an assumption by the Manville Trust of the liability for its income taxes.
The Johns Manville board, other than Johns Manville directors who were trustees
of the Manville Trust, met on two occasions during December 1998 to discuss the
possible settlement of the tax liability and receive the advice of J.P. Morgan.
In late December 1998, Johns Manville and the Manville Trust tentatively agreed
to a payment of $90,000,000 to be made by Johns Manville to the Manville Trust,
subject to the consummation of a merger or sale transaction, in return for the
Manville Trust's agreement to indemnify Johns Manville against its statutory
liability for federal income taxes accruing on income of the designated
settlement fund portion of the Manville Trust and to eliminate Johns Manville's
contractual liability to the Manville Trust for the payment of the Manville
Trust's income taxes.

     At a meeting of the Johns Manville board held on January 20, 1999, J.P.
Morgan reviewed its analysis of various alternatives that might be available to
Johns Manville. Robert A. Falise, a Johns Manville director and Chairman and
Managing Trustee of the Manville Trust, reported to the Johns Manville board
that the trustees of the Manville Trust had concluded that the Manville Trust
would explore alternatives with respect to the sale of its ownership interest in
Johns Manville and would support Johns Manville in its exploration of
alternatives which would accomplish the objective. At this meeting, Johns
Manville's board determined to pursue the exploration of a sale or merger of
Johns Manville. The Johns Manville board also discussed establishing a board
committee to provide oversight and guidance in connection with the exploration
of strategic alternatives and created a special committee composed of Messrs.
Falise, Michael N. Hammes and Charles L. Henry, Chief Executive Officer of Johns
Manville. Also as of January 20, Johns Manville entered into an engagement
letter with J.P. Morgan for J.P. Morgan to act as its exclusive financial
advisor in connection with any sale, merger or business combination.

     On January 25, 1999, Johns Manville issued a press release publicly
announcing that it would undertake a review of strategic alternatives available
to maximize shareholder value and that such alternatives included a possible
sale or merger of Johns Manville.

     Following the issuance of the January 25 press release and through early
February 1999, J.P. Morgan and Goldman Sachs contacted approximately 50
prospective purchasers, and responded to inquiries from others, in order to
determine whether there was an interest in considering a sale or merger
transaction involving Johns Manville. Interested entities were provided with
confidential information concerning Johns Manville.

                                       26
<PAGE>   36

     In mid-February 1999, J.P. Morgan and Goldman Sachs requested parties that
had continued to participate in the review process to provide written
preliminary indications of interest with respect to a possible transaction.
Indications of interest were received from several entities, including Hicks,
Muse. Notwithstanding these preliminary indications of interest, and continued
due diligence by several parties, by mid-April 1999, it became apparent that the
process would not result in acceptable bids being obtained.

     The Johns Manville board was updated as to these developments at a meeting
held on April 19, 1999, and on April 20, 1999, Johns Manville issued a press
release to that effect. The press release also stated that Johns Manville and
the Manville Trust would explore other options to maximize shareholder value,
including a possible secondary offering of Johns Manville common stock by the
Manville Trust, as well as a stock buyback by Johns Manville.

     In July 1999, in lieu of an offering of the Manville Trust of shares of its
Johns Manville common stock, Johns Manville repurchased 12,196,291 shares of
Johns Manville common stock from the Manville Trust based on the average of the
closing sales price of Johns Manville common stock for the prior twenty trading
days ($13.675 per share) and prepaid its remaining outstanding indebtedness to
the Manville Trust at its estimated then-present value. The aggregate amount
paid to the Manville Trust in these transactions was approximately $200,000,000,
which was the estimated amount of Johns Manville's 1999 taxable income that
could be offset by reason of these transactions.

     In June 1999, Johns Manville engaged in discussions with a leveraged buyout
firm concerning a possible acquisition of Johns Manville. This firm had been
contacted in the auction process, but had not provided an indication of interest
at that time. Later in June 1999, that firm submitted a preliminary proposal
relating to a recapitalization transaction in which each share of Johns Manville
common stock, other than a portion of the shares of common stock held by the
Manville Trust to be retained in the continuing entity, would be converted into
consideration comprised of $14.00 per share in cash and $2.00 in liquidation
preference of preferred stock. The preliminary proposal was subject to the
receipt of financing and the completion of due diligence.

     In early July 1999, the leveraged buyout firm executed a confidentiality
agreement with Johns Manville in connection with its review of a potential
transaction and began to conduct due diligence. Later in July 1999, the
leveraged buyout group advised representatives of Johns Manville that it would
be prepared to pursue a transaction at a cash price of $15.00 per share.
Following discussions between J.P. Morgan and that firm and based on J.P.
Morgan's willingness to underwrite the sale of the preferred stock contemplated
in that firm's earlier offer, that firm's offer was revised to $15.63 in cash.

     At a meeting of the Johns Manville board held on August 2, 1999, the board
created a special committee comprised of Messrs. Falise, Hammes and William E.
Mayer to review, negotiate, evaluate and recommend to the Johns Manville board
what action should be taken with respect to the proposal received from the
leveraged buyout firm.

     In September 1999, the leveraged buyout firm informed representatives of
Johns Manville that it was not willing to pursue a transaction at the price
level previously indicated, although it would be willing to consider a
transaction at a lower price. This development was discussed by the special
committee at a meeting held on September 22, 1999. At that meeting the special
committee determined to recommend to the Johns Manville board that Johns
Manville not pursue, and Mr. Falise advised the special committee that the
Manville Trust had determined that it did not wish to pursue, such a transaction
at that time. Thereafter, talks with the leveraged buyout firm were terminated.

     Later in 1999, Johns Manville received an oral indication of interest from
a company in the building products industry, relating to a possible acquisition
of Johns Manville. Following discussions between representatives of that company
and senior management of Johns Manville and representatives of J.P. Morgan, this
company determined not to pursue any proposal.

     In January 2000, Johns Manville received an oral indication of interest
from a company in the building products industry relating to a possible
acquisition of Johns Manville. This entity had participated in the process
conducted in early 1999 and had conducted due diligence, but had declined to
submit a
                                       27
<PAGE>   37

proposal at that time. After preliminary discussions with representatives of
Johns Manville and J.P. Morgan, this company determined not to pursue any
proposal.

     On February 3, 2000, Johns Manville issued a press release publicly
announcing that Mr. Henry intended to retire effective March 31, 2000. Shortly
after that, in February 2000, Johns Manville and the Manville Trust were
contacted by a stockholder of Johns Manville that indicated it was interested in
pursuing a transaction with Johns Manville. This stockholder subsequently
entered into a confidentiality agreement with Johns Manville. Separately,
representatives of Johns Manville, the stockholder and Bear Stearns met in
February to discuss a possible transaction between Bear Stearns and Johns
Manville. Subsequent to that meeting, Bear Stearns entered into a
confidentiality agreement with Johns Manville.

     On March 3, 2000, Mr. Falise received a letter from Bear Stearns Merchant
Banking expressing interest in pursuing a transaction involving Johns Manville
in which consideration was offered to the stockholders of Johns Manville (other
than with respect to a portion of the shares of Johns Manville common stock to
be retained by the Manville Trust in the continuing entity) of $13.625 per share
in cash plus $2.00 in liquidation preference of a 13% pay-in-kind preferred
stock, with a requirement that the Manville Trust would reinvest approximately
$50,000,000 in value of its Johns Manville common stock in the continuing
entity. The proposal contemplated that Bear Stearns would provide approximately
$250,000,000 of the equity financing anticipated to be required in connection
with the transaction, and would syndicate the remaining proposed equity
investment to other investors. As a condition to proceeding with development of
its proposal, Bear Stearns required that Johns Manville enter into an
exclusivity arrangement, among other things, prohibiting Johns Manville and the
Manville Trust from soliciting third party proposals or engaging in negotiations
with any third party for a thirty-day period.

     On March 7, 2000, a regularly scheduled meeting of the Johns Manville board
was held. During this meeting, the board discussed the Bear Stearns proposal
without members of Johns Manville management being present. The Johns Manville
board determined to encourage Bear Stearns to continue to pursue development of
its proposal. The Johns Manville board also considered the request that had been
made by Bear Stearns for an exclusivity agreement. The board determined that it
would be willing to agree to such an arrangement subject to clarifying certain
aspects of Bear Stearns' proposal. Also at that meeting, the board appointed a
special committee composed of Messrs. Falise, Hammes and Mayer to review,
negotiate, evaluate and recommend to the Johns Manville board what action should
be taken with respect to the proposal of Bear Stearns. Mr. Todd Goodwin was
subsequently added to the committee.

     On March 15, 2000 the special committee met to be updated regarding the
status of Bear Stearns' activities. On March 16, 2000, after clarification of
elements of Bear Stearns' proposal, Johns Manville and the Manville Trust
entered into an exclusivity agreement with Bear Stearns for a 30-day period.

     Following the execution of the exclusivity agreement, Bear Stearns began to
perform a due diligence review based on public and confidential information
provided by Johns Manville. In addition, Bear Stearns met with management and
other potential equity investors to develop their proposal. During this time,
Hicks, Muse agreed to participate with Bear Stearns in providing the equity
financing for the proposed transaction.

     On March 31, Johns Manville issued a press release publicly announcing that
Mr. Henry had agreed to postpone his retirement until June 30, 2000.

     On April 4, 2000, the special committee met to receive an update on the
status of the Bear Stearns/ Hicks, Muse proposal.

     On April 7, 2000, Bear Stearns and Hicks, Muse submitted a written proposal
to Johns Manville with respect to a transaction including the following
elements:

     - consideration to stockholders of Johns Manville (other than with respect
       to shares of common stock to be retained by the Manville Trust and some
       members of management in the continuing entity) of $13.625 per share in
       cash and $2.00 per share in 13% pay-in-kind preferred stock;

                                       28
<PAGE>   38

     - the agreement by the Manville Trust to reinvest approximately $50,000,000
       in value of its existing shares in the continuing entity;

     - the agreement by members of management to reinvest approximately
       $15,000,000 in value of their Johns Manville equity interest in the
       continuing entity and the participation of Mr. Henry in the transaction;
       and

     - the payment of $90,000,000 by Johns Manville to the Manville Trust in
       return for the Manville Trust relieving Johns Manville of its statutory
       and contractual liability for future Manville Trust income taxes.

     In order to proceed with their proposal, Hicks, Muse and Bear Stearns
required that Johns Manville and the Manville Trust agree to extend the
exclusivity arrangement.

     On April 10, 2000, the Johns Manville board met to consider the Hicks,
Muse/Bear Stearns group proposal. At that meeting, it was reported that Johns
Manville and J.P. Morgan had been orally contacted by an investment banking firm
representing an industrial company with an interest in pursuing an acquisition
of Johns Manville. The board considered this indication of interest and the
requirement of the Hicks, Muse/Bear Stearns group that the exclusivity agreement
be extended. The board determined to extend the exclusivity agreement and it was
extended on April 13, 2000.

     The amended exclusivity agreement provided, among other things, that for a
30-day period (subject to a 15-day extension upon notice by either party) Johns
Manville would not solicit or engage in negotiations relating to any third party
proposal. Notwithstanding the foregoing, however, Johns Manville would be
entitled to pursue a superior proposal following notice to Hicks, Muse and Bear
Stearns, subject to an obligation to pay out-of-pocket expenses of Hicks, Muse
and Bear Stearns not in excess of $10,000,000 if Johns Manville entered into an
agreement with respect to a competing transaction with any third party with whom
Johns Manville engaged in the prohibited activities during the exclusivity
period. The Manville Trust also entered into this amended exclusivity agreement.

     On April 24, 2000, the Johns Manville special committee received from the
industrial company a written proposal for the acquisition of Johns Manville. The
proposal contemplated a transaction in which all of Johns Manville's outstanding
shares would be acquired for $15.50 per share in cash and a $75,000,000 payment
would be made to the Manville Trust over a five-year period in satisfaction of
all obligations of Johns Manville to the Manville Trust. The proposal was
subject to conditions including completion of a due diligence review and
negotiation of definitive documentation with Johns Manville and the Manville
Trust. A special committee meeting was held on April 25, 2000 to discuss the
letter, and a Johns Manville board meeting was held on April 26 at which the
board considered the status of the proposed transaction with the Hicks,
Muse/Bear Stearns group and the letter received on April 24. The Johns Manville
board determined, and Mr. Falise advised the Johns Manville board that the
Manville Trust had determined, not to pursue this proposal at that time. On
April 27, the special committee advised that interested party of this
determination.

     On May 12, 2000, at a regularly scheduled meeting, the Johns Manville board
discussed the status of the Hicks, Muse/Bear Stearns group proposal, and the
terms of a second letter received that day from the industrial company. The
letter reiterated the proposal that had been conveyed previously. On May 12,
2000, Hicks, Muse and Bear Stearns provided notice extending the exclusivity
period by an additional 15 days to May 28, 2000.

     On May 15, 2000, the special committee met to discuss the letter and to
receive an update on the Hicks, Muse/Bear Stearns group proposal. The special
committee concluded that there had been no change in the proposal or the
circumstances of the Hicks, Muse/Bear Stearns group proposal that would lead the
committee to change the position adopted at the April 26 board meeting.

     On May 16, 2000, the Hicks, Muse/Bear Stearns group's counsel provided to
Johns Manville and its counsel, a draft merger agreement in connection with the
proposed transaction. At the same time, the Hicks, Muse/Bear Stearns group's
counsel provided to the Manville Trust and its counsel, a draft voting
                                       29
<PAGE>   39

agreement with respect to the Manville Trust's shares of Johns Manville common
stock. Also on May 16, the special committee responded to the letter received
from the industrial company, stating that it did not wish to pursue such
proposal at that time.

     At a meeting of the special committee on May 19, 2000, representatives of
Johns Manville updated the special committee concerning developments in the
proposed transaction, and described for the special committee the terms of the
agreements received from the Hicks, Muse/Bear Stearns group. Issues discussed
with the special committee included the proposed terms of the pay-in-kind
preferred stock, transaction structure, conditions to closing and termination
events and fees.

     On May 21, 2000, representatives of John Manville provided written comments
on the draft merger agreement, and representatives of the Manville Trust
provided written comments on the draft voting agreement, to representatives of
the Hicks, Muse/Bear Stearns group. Counsel to the parties met for the first
time on May 24, 2000 to commence negotiations on the agreements. Issues
discussed at this meeting included the proposed terms of the pay-in-kind
preferred stock, transaction structure, conditions to closing and termination
events and a $110,000,000 termination fee requested by the Hicks, Muse/Bear
Stearns group. In the course of the May 24 meeting, counsel to the Hicks,
Muse/Bear Stearns group conveyed the requirement of the Hicks, Muse/Bear Stearns
group that the exclusivity agreement be extended beyond the May 28, 2000
expiration date.

     On May 26, 2000, the special committee met to receive an update from Johns
Manville's advisors concerning the ongoing negotiations with the Hicks,
Muse/Bear Stearns group. Topics reviewed with the special committee included the
terms of the pay-in-kind preferred stock, conditions to closing, termination
events and termination fees. In addition, the special committee discussed the
Hicks, Muse/Bear Stearns group's request for an extension of the exclusivity
agreement. The special committee determined to grant the exclusivity extension
only if agreement could be obtained on an acceptable termination fee that would
be applicable if a transaction were eventually agreed to.

     Following the May 26 meeting, members of the committee, together with
representatives of J.P. Morgan and Goldman Sachs, contacted representatives of
the Hicks, Muse/Bear Stearns group to discuss the termination fee. The
representatives of the Hicks, Muse/Bear Stearns group stated that without
continued exclusive dealing and a substantial termination fee, they would be
unwilling to proceed with the transaction. Following negotiations, the parties
agreed that they would proceed on the basis of a $53,000,000 termination fee
plus out-of-pocket expenses of up to $12,500,000, to be reflected in any
executed merger agreement, payable in connection with certain terminations. For
a further description of the Merger Agreement see the "Merger Agreement".

     On May 27, 2000, the exclusivity agreement was extended for a period ending
on June 16, 2000, subject to continuation thereafter unless notice of
termination was provided by either party.

     Discussions and meetings between representatives of the parties continued
following the extension. Special committee meetings were held on June 7 and June
16, 2000 in order for the committee to receive updates as to the progress of
negotiations and to provide direction to Johns Manville's legal counsel and
financial advisor. Significant issues resolved during this period included the
principal terms of the pay-in-kind preferred stock, the conditions to the
parties' closing obligations, the circumstances under which the merger agreement
and voting agreement could be terminated and the circumstances in which a
termination fee and/or expenses would be payable.

     On June 20, 2000, the industrial company sent a third letter to Johns
Manville offering to acquire all of the outstanding shares of Johns Manville
common stock on substantially the same terms previously indicated.

     A special meeting of the Johns Manville board was held on June 22, 2000 to
consider the proposed transaction with the Hicks, Muse/Bear Stearns group. At
this meeting, the board was updated on the progress of negotiations. The board
received a financial presentation from J.P. Morgan and received the opinion of
J.P. Morgan to the effect that the $13.625 in cash and 0.02 of a share of
pay-in-kind preferred stock to be received by holders of Johns Manville common
stock in the merger was fair, from a financial
                                       30
<PAGE>   40

point of view, to such stockholders. The Johns Manville board reviewed the terms
of the proposed merger agreement, the amendment to the restated certificate of
incorporation, the voting agreement and the exchange agreement. The Johns
Manville Board also considered the June 20, 2000 letter from the industrial
company. Mr. Henry was excused from much of the board meeting.

     At the time, the Johns Manville board also considered approval of the tax
agreement and related agreements. The directors who are also trustees of the
Manville Trust excused themselves from the meeting. The Johns Manville board
(without the trustee/directors) reviewed the terms of these agreements, and the
directors received a presentation from J.P. Morgan regarding its analysis of the
tax agreement and received the opinion of J.P. Morgan to the effect that the
$90,000,000 consideration to be paid to the Manville Trust pursuant to the tax
agreement was fair, from a financial point of view, to the holders of Johns
Manville common stock other than the Manville Trust for the assumption by the
Manville Trust of the tax liabilities. The Johns Manville board then approved
the tax agreement and agreements related to it.

     Following the approval of the tax agreements, the special committee met to
discuss the proposed transactions, and recommended that the Johns Manville board
approve the proposed merger agreement and the transactions contemplated thereby.

     When the Johns Manville board reconvened, it received the recommendation of
the special committee, and Mr. Falise informed the board that the Manville Trust
had approved the agreements to which it would be a party. The Johns Manville
board then voted to approve the amendment to the restated certificate of
incorporation, the merger agreement and the transactions contemplated thereby
and determined them to be advisable. The Johns Manville board also approved the
related agreements.

RECOMMENDATION OF THE JOHNS MANVILLE BOARD; REASONS FOR THE MERGER

     On June 22, 2000 the Johns Manville board voted to approve the amendment to
the restated certificate of incorporation and the merger agreement and the
transactions contemplated thereby, including the merger, and determined them to
be advisable. The Johns Manville board also determined to recommend that Johns
Manville stockholders vote in favor of approval of the amendment and adoption of
the merger agreement and approval of the transaction contemplated thereby.

     In reaching its determination to approve the merger agreement and the
transactions contemplated thereby and to declare the advisability of the merger
agreement, the Johns Manville board consulted with Johns Manville's management,
financial advisor and legal counsel. Set forth below are the material factors
that the board considered in reaching this determination:

          (1) the board's review of Johns Manville's business, operations,
     financial condition, earnings and prospects;

          (2) the board's review of possible alternatives to a merger
     transaction, the potential value to stockholders of these alternatives and
     the timing and likelihood of actually consummating any of these
     alternatives or achieving additional value from these alternatives,
     including the possibility that Johns Manville's future performance might
     not lead to a stock price having a higher present value than the merger
     consideration to be received by holders of Johns Manville common stock in
     the merger;

          (3) the financial terms of the merger, including the cash and
     pay-in-kind preferred stock payable in the merger upon conversion of Johns
     Manville common stock, and the continuing equity investment of the Manville
     Trust and some members of management in the surviving corporation;

          (4) the financial presentation of J.P. Morgan and the opinion of J.P.
     Morgan to the effect that, as of the date thereof, the $13.625 in cash and
     0.02 of a share of pay-in-kind preferred stock to be received by holders of
     Johns Manville common stock in the merger was fair, from a financial point
     of view, to such stockholders;

          (5) that the common stockholders of Johns Manville who do not become
     common stockholders of the surviving corporation in the merger will no
     longer be able to participate in the potential growth
                                       31

     of Johns Manville following the merger through a common equity ownership
     interest, but will only be entitled to dividends paid on the pay-in-kind
     preferred stock in return for their continuing investment in Johns
     Manville;

          (6) that the merger was agreed to by the board only after issuance by
     Johns Manville of a press release in January 1999 regarding its review of
     strategic alternatives, significant publicity concerning the review by
     Johns Manville of its strategic alternatives, the passage of a significant
     period of time between issuance of the press release and approval of the
     merger agreement, and contact with, and due diligence by, a number of
     potential bidders over an extended period of time;

          (7) the arms' length negotiations between representatives of Johns
     Manville, including the special committee, and the Hicks, Muse/Bear Stearns
     investor group with respect to the consideration to be paid in the merger
     and the other material terms of the merger agreement and other agreements;

          (8) that the closing price per share of Johns Manville common stock on
     June 22, 2000, the last trading day prior to the public announcement of the
     execution of the merger agreement, was $12.3125, and the closing price of
     $14.8125 per share of Johns Manville common stock on August 26, 1999 was
     the highest price at which the Johns Manville common stock traded in the
     twelve months prior to execution of the merger agreement;

          (9) the possibility that if the merger were not to be consummated, the
     price of Johns Manville's common stock could decline below the current
     trading price;

          (10) the terms of the merger agreement, including

            - the structure of the transaction,

            - the restrictions on the conduct of Johns Manville's business
              pending closing,

            - the conditions to the parties' obligations to consummate the
              merger,

            - the fees and expenses that would become payable by Johns Manville
              in the event of a termination of the merger agreement under
              certain circumstances,

            - the terms of Johns Manville's non-solicitation covenant, which
              permits Johns Manville to provide information to and negotiate
              with, and, upon payment of a termination fee and out-of-pocket
              expenses of Hicks, Muse and Bear Stearns, to terminate the merger
              agreement to enter into a transaction with a third party relating
              to an unsolicited proposal made following the date of the merger
              agreement that the Johns Manville board determines is more
              favorable to stockholders than the transactions contemplated by
              the merger agreement;

          (11) the terms of the voting agreement between HB Merger LLC and the
     Manville Trust, including the fact that following receipt of an order of
     the U.S. bankruptcy court, the Manville Trust will be obligated to vote in
     favor of adoption of the merger agreement at the stockholders meeting, and
     that assuming that the conditions to the Manville Trust's voting obligation
     under the voting agreement are satisfied and that the merger agreement is
     not otherwise terminated, sufficient votes will be cast for adoption of the
     merger agreement to ensure its passage without the vote of any other
     stockholder;

          (12) the expected continued equity participation in Johns Manville of
     the Manville Trust and some members of Johns Manville senior management,
     including Mr. Henry;

          (13) the likelihood of consummation of the merger, including the fact
     that, by reason of certain conditions to the obligations of HB Merger LLC
     and HB Finance LLC to consummate the merger, including conditions
     concerning receipt of financing and the timing of the closing, it is
     possible that the merger may not be consummated even if approved by
     stockholders; and

          (14) the reputations of Hicks, Muse and Bear Stearns, as well as the
     equity and debt financing commitments provided and the investor group's
     financial ability to complete the merger, including the fact that all of
     the funds expected to be necessary to complete the merger have been
     committed pursuant to commitment letters, subject to certain conditions.

     In view of the wide variety of factors considered in connection with its
evaluation of the merger and the complexity of these matters, the Johns Manville
board did not attempt to quantify, rank or otherwise assign relative weights to
these factors. In addition, the Johns Manville board did not undertake to make
any specific determination as to whether any particular factor, or any aspect of
any particular factor, was favorable or unfavorable to the board's ultimate
determination, but rather the Johns Manville board conducted an overall analysis
of the factors described above, including thorough discussions with and
questioning of management and Johns Manville's legal and financial advisors. In
considering the factors described above, individual members of the Johns
Manville board may have given different weight to different factors. Considering
all these factors as a whole, the Johns Manville board considered the factors to
be favorable to and to support its determination.

     The Johns Manville board considered the fact that by virtue of its stock
ownership, the Manville Trust may cast sufficient votes at the stockholders
meeting to ensure approval of the amendment to the restated certificate of
incorporation and adoption of the merger agreement and the transactions
contemplated thereby. The Johns Manville board was aware of the terms of the
voting agreement requiring the Manville Trust to vote in favor of the amendment
to the restated certificate of incorporation and the adoption of the merger
agreement, subject to certain conditions. Notwithstanding that the transaction
is not structured to require the approval of a majority of the Johns Manville
common stock held by stockholders unaffiliated with the Hicks, Muse/Bear Stearns
group, the Johns Manville board believed that, while the Manville Trust has some
interests in the merger agreement differing from those of other stockholders,
the Manville Trust's interests in obtaining a transaction that would be
beneficial to it as a holder of Johns Manville common stock were generally
aligned with the interests of other stockholders. The Johns Manville board
believed that the substantive and procedural fairness of the transactions was
established by the process pursued by the board and the special committee and
the factors set forth above.

     The Johns Manville board believes that approval of the amendment to the
restated certificate of incorporation and adoption of the merger agreement are
advisable and fair to all stockholders, including unaffiliated stockholders, for
the reasons set forth above. In the course of their deliberations, the special
committee and the Johns Manville board considered the appropriateness and
fairness to Johns Manville's stockholders of the alternatives being considered
and the process pursued, as well as the terms of the merger agreement. The
proposed transactions were approved by all of the directors present at the vote,
thereof, which included a majority of the directors on the Johns Manville board
who are neither employees of Johns Manville nor trustees of the Manville Trust.
In light of these factors, neither the Johns Manville board nor the special
committee considered it necessary to retain any other unaffiliated
representative to act solely on behalf of the unaffiliated stockholders of Johns
Manville for the purpose of negotiating the terms of the merger agreement.

     HB Merger LLC and HB Finance LLC have advised Johns Manville that they
regard the acquisition of Johns Manville to be an attractive investment
opportunity because they believe that Johns Manville's future business prospects
are favorable and that the anticipated high debt-to-equity ratio of the
surviving corporation will allow the net worth of the surviving corporation to
increase more rapidly on a percentage basis than the net worth of an identical
corporation with a larger equity base and less debt. The investment, however,
will involve a substantial risk to the holders of the surviving corporation
common stock because of the high debt-to-equity ratio of the surviving
corporation and its subsidiaries following the merger. Based solely on the fact
that the terms of the merger agreement were the result of arms' length
negotiations with Johns Manville, the Manville Trust and their advisors, HB
Merger LLC and HB Finance LLC believe that the merger consideration is fair to
Johns Manville stockholders. This belief, however, should not be construed as a
recommendation to Johns Manville's stockholders to vote to approve the amendment
to the restated certificate of incorporation of Johns Manville, the merger
agreement or the transactions contemplated thereby.

OPINIONS OF J.P. MORGAN

  Opinion of J.P. Morgan regarding the Merger

     Pursuant to an engagement letter dated January 20, 1999, Johns Manville
retained J.P. Morgan to act as its exclusive financial advisor in connection
with any sale, merger or business combination. At the Johns Manville board
meeting on June 22, 2000, J.P. Morgan gave its oral opinion, subsequently
confirmed in writing, to the board that as of that date and on the basis of and
subject to the matters described in the opinion, the per share consideration of
$13.625 in cash and 0.02 of a share of pay-in-kind preferred stock, to be
received by holders of Johns Manville common stock in the proposed merger was
fair, from a financial point of view, to such stockholders.

     The full text of the written opinion of J.P. Morgan dated June 22, 2000,
which sets forth the assumptions made, matters considered and limits on the
review undertaken, is attached as Appendix C to this proxy statement/prospectus.
Johns Manville incorporates J.P. Morgan's opinion into this proxy statement by
reference and encourages you to read the opinion carefully and in its entirety.

     J.P. Morgan's opinion is addressed to the Johns Manville board of
directors, is directed only to the consideration to be received by holders of
Johns Manville common stock in the proposed merger and does not constitute a
recommendation to any stockholder as to how to vote with respect to the proposed
merger or at what price the pay-in-kind preferred stock will trade at any future
time.

     In arriving at its opinion, J.P. Morgan reviewed, among other things:

     - the merger agreement;

     - certain publicly available information concerning Johns Manville's
       business and of certain other companies engaged in businesses comparable
       to Johns Manville, and the reported market prices for certain other
       companies' securities J.P. Morgan deemed comparable;

     - publicly available terms of certain transactions involving companies
       comparable to Johns Manville and the terms of other transactions J.P.
       Morgan deemed relevant;

     - then-current and historical market prices of Johns Manville common stock;

     - Johns Manville's audited financial statements for the fiscal year ended
       December 31, 1999, and its unaudited financial statements for the period
       ended March 31, 2000;

     - certain agreements with respect to Johns Manville's outstanding
       indebtedness or obligations;

     - certain internal financial analyses and forecasts prepared by Johns
       Manville's management;

     - the voting agreement, between the HB Merger LLC and the Manville Trust;

     - the commitment letters relating to the financing contemplated by the
       Hicks, Muse/Bear Stearns group; and

     - the draft tax agreement, between Johns Manville and the Manville Trust.

     In addition, J.P. Morgan has held discussions with some members of Johns
Manville management and the Hicks, Muse/Bear Stearns group with respect to
certain aspects of the merger, and Johns Manville's past and current business
operations, financial condition and future prospects and operations, the effects
of the proposed merger on Johns Manville's financial condition and future
prospects, and certain other matters J.P. Morgan believed necessary or
appropriate to its inquiry. J.P. Morgan has visited certain of Johns Manville's
representative facilities. J.P. Morgan also reviewed such other financial
studies and analyses and considered such other information as it deemed
appropriate for the purposes of its opinion.

     In giving its opinion, J.P. Morgan relied upon and assumed, without
independent verification, the accuracy and completeness of all information that
was publicly available or was furnished to it by Johns Manville or the Hicks,
Muse/Bear Stearns group or otherwise reviewed, and has not assumed any
responsibility or liability therefor. J.P. Morgan did not conduct any valuation
or appraisal of any assets or

                                       34
<PAGE>   44

liabilities of Johns Manville, nor were any such valuations or appraisals
provided to J.P. Morgan. In relying on financial analyses and forecasts provided
to it, J.P. Morgan assumed that they were reasonably prepared based on
assumptions reflecting the best currently available estimates and judgments of
Johns Manville's management as to the expected future results of operations and
financial condition to which such analyses or forecasts relate. J. P. Morgan
also assumed that the proposed merger will have the tax consequences described
in discussions with, and materials furnished to J.P. Morgan by, Johns Manville's
representatives, and that the other transactions contemplated by the merger
agreement will be consummated as described in such agreement. J.P. Morgan relied
as to all legal matters relevant to rendering its opinion upon the advice of
counsel.

     In its opinion, J.P. Morgan noted that the proposed merger follows a full
public auction process in which J.P. Morgan broadly solicited offers for Johns
Manville from January through April 1999 and that subsequent to such auction
process Johns Manville and J.P. Morgan have had discussions with several other
potential buyers which did not result in a business combination transaction and
that J.P. Morgan took such circumstances into account in rendering its opinion.

     J.P. Morgan based its opinion on economic, market and other conditions as
in effect on, and the information made available to J.P. Morgan, as of June 22,
2000. Subsequent developments may affect J.P. Morgan's opinion and J.P. Morgan
does not have any obligation to Johns Manville to update, revise or reaffirm its
opinion.

     The following is a summary of the material financial analyses performed by
J.P. Morgan in connection with its opinion. We have presented some of the
summaries of the financial analyses in tabular format. In order to understand
the financial analyses used by J.P. Morgan more fully, you should read the
tables together with the text of each summary. The tables alone do not
constitute a complete description of J.P. Morgan's financial analyses and this
summary contains all material financial analyses, but is not a complete
description of all of the analyses underlying J.P. Morgan's opinion.

     Historical Common Stock Performance. J.P. Morgan conducted an analysis of
the historical closing price of Johns Manville's common stock based on closing
prices on the New York Stock Exchange relative to the share price performance of
Armstrong Holdings Inc., USG Corporation, Owens Corning Inc. and the Standard &
Poor's 500 index over the time periods from May 1, 1998 to June 21, 2000 and
March 1, 2000 to June 21, 2000. J.P. Morgan noted that Johns Manville's common
stock has outperformed the common stocks of Armstrong Holdings Inc., USG
Corporation and Owens Corning Inc. over the time period from May 1, 1998 to June
21, 2000. J.P. Morgan also found that Johns Manville's common stock outperformed
Armstrong Holdings Inc., USG Corporation, Owens Corning Inc. and the Standard &
Poor's 500 index over the time period from March 1, 2000 to June 21, 2000.

     Discounted Cash Flow Analysis. J.P. Morgan conducted a discounted cash flow
analysis for the purpose of determining the implied fully diluted equity value
per share for Johns Manville's common stock. J.P. Morgan reviewed two scenarios,
one which included management's base case which reflected management's latest
estimates for fiscal 2000 and management's strategic plan for the fiscal years
2001 through 2004. The other scenario analyzed a sensitivity case that was based
on management's projections assuming an economic recession in 2001.

     For both scenarios, J.P. Morgan calculated the unlevered free cash flows
that Johns Manville is expected to generate during fiscal years 2000 through
2004. J.P. Morgan also calculated a range of terminal asset values of Johns
Manville at the end of fiscal 2004 by calculating a range of estimated terminal
cash flows and valuing such estimated terminal cash flows as perpetuities. J.P.
Morgan calculated estimated terminal cash flows based upon EBIT (earnings before
interest and taxes) margins and growth rates taking into account EBIT margins
and growth rates achieved by Johns Manville over the last 11 years and EBIT
margins and growth rates predicted by management for the fiscal years 2000
through 2004. The unlevered free cash flows and the range of terminal asset
values were then discounted to present values using a range of discount rates
from 10.00% to 12.00%, which were chosen by J.P. Morgan based upon an analysis
of Johns Manville's weighted average cost of capital. The present value of the
unlevered free cash flows and the range of terminal asset values were then
adjusted for estimated May 31, 2000
                                       35
<PAGE>   45

excess cash, option exercise proceeds, total debt and additional debt in
connection with the settlement of Johns Manville's tax liability to the Manville
Trust. Based on the projections and a range of discount rates from 10.00% to
12.00%, the discounted cash flow analysis indicated a range of equity values
utilizing base case projections of between $12 and $18 per share of Johns
Manville's common stock and utilizing sensitivity case projections between $10
and $16 per share of Johns Manville's common stock of Johns Manville's common
stock, each on a stand-alone basis.

     Public Trading Multiples. Using publicly available information, J.P. Morgan
compared selected financial data, ratios and multiples of Johns Manville with
similar data, ratios and multiples for selected publicly traded companies
engaged in businesses which J.P. Morgan judged to be analogous to Johns
Manville.

     The companies selected by J.P. Morgan were:

         Armstrong World Industries, Inc.
         USG Corporation
         Owens Corning
         Carlisle Companies Incorporated
         PPG Industries, Inc.
         Masco Corporation
         The Black and Decker Corporation
         The Stanley Works
         Sherwin Williams Company

     For each of these companies, publicly available information for the twelve
months ended December 31, 1999 was used. In addition, J.P. Morgan derived
estimates of sales, EBITDA (earnings before interest, taxes, depreciation and
amortization), and net income for calendar year 2000 from public equity analyst
estimates. The analysis produced a range of multiples for firm value (which J.P.
Morgan defined for purposes of its analyses as market value of common equity and
preferred stock as of June 21, 2000 plus latest reported debt, net of cash and
marketable securities and minority interests) over various estimated financial
benchmarks, including sales and EBITDA, and for the market value of common
equity (price) over net income (the price-to-net income (earnings) multiple or
P/E ratio). The analysis indicated firm value to 1999 EBITDA multiples ranging
from 2.6x to 9.1x and firm value to projected 2000 EBITDA ranging from 2.7x to
7.6x. The analysis also indicated 1999 P/E ratios ranging from 3.1x to 15.2x and
2000 P/E ratios ranging from 3.0x to 13.5x. Based upon these ranges of multiples
and Johns Manville's estimates for 2000 EBITDA, J.P. Morgan found that based
upon a reference range of 4.0x-5.0x 2000 EBITDA, the implied equity value per
Johns Manville common share would be approximately $11 to $14. J.P. Morgan also
calculated that Johns Manville's implied equity value per common share using
Johns Manville's estimate for 2000 net income based upon a reference range of
5.0x -- 7.0x 2000 net income would be approximately $8 to $12.

     J.P. Morgan also calculated reference ranges for equity value per common
share based upon applying an illustrative 30% control premium to these reference
ranges. J.P. Morgan indicated that a 30% control premium was reasonable for this
illustrative analysis based on its review of 2,703 U.S. control transactions for
the period from 1988 through 1999 and 143 U.S. control transactions through the
first five months of 2000. On that basis, J.P. Morgan calculated the control
premium adjusted range of Johns Manville equity value per share based on the
analysis of public trading multiples to be $14 -- $19 based upon firm value to
2000 EBITDA and $11 -- $15 based upon 2000 P/E.

     Selected Transaction Analysis. Using publicly available information, J.P.
Morgan examined selected transactions in the building products industry.

</TABLE>

     J.P. Morgan calculated a range of multiples of firm value to EBIT (for the
twelve month periods prior to the respective transaction announcements) implied
in these transactions. J.P. Morgan noted that the range of EBIT multiples
implied by these transactions ranged from 5.5x to 15.0x.

     Pay-in-kind preferred stock analysis: J.P. Morgan analyzed the potential
value of the pay-in-kind preferred stock to be received by holders of Johns
Manville common stock in the merger and calculated the implied value per Johns
Manville common share based upon potential effective yields ranging from 13.0%
to 22.0%. J.P. Morgan deemed this range of yields for this security to be
reasonable in light of current market conditions for similar securities. J.P.
Morgan determined that such range of yields implied a potential value for each
0.02 of a share of the pay-in-kind preferred stock to be paid per Johns Manville
common share of $0.82 to $2.00.

     Analysis of Johns Manville tax asset. J.P. Morgan analyzed the potential
maximum value of Johns Manville's tax asset, which is the tax deductions that
Johns Manville will receive when the Manville Trust sells some of its stock of
Johns Manville in the merger, by reviewing potential utilization periods for the
tax asset and determining the present values of potential tax savings by
discounting those potential tax savings by discount rates ranging from 10.0% to
18.0%. This analysis indicated a potential maximum value of the tax asset per
Johns Manville common share in the range of approximately $1 to $4.

     The summary set forth above is not a complete description of the analyses
or data presented by J.P. Morgan. The preparation of a fairness opinion is a
complex process and is not necessarily susceptible to partial analysis or
summary description. J.P. Morgan believes that you must consider its opinion,
the summary and its analyses as a whole. Selecting portions of this summary and
these analyses, without considering the analyses as a whole, would create an
incomplete view of the processes underlying the analyses and opinion. In
arriving at its opinion, J.P. Morgan considered the results of all of the
analyses as a whole. No single factor or analysis was determinative of J.P.
Morgan's fairness determination. Rather, the totality of the factors considered
and analyses performed operated collectively to support its determination. J.P.
Morgan based its analysis on assumptions that it deemed reasonable, including
assumptions concerning general business and economic conditions and industry
specific factors. This summary sets forth under the description of each analysis
the other principal assumptions upon which J.P. Morgan based that analysis.
Analyses based upon forecasts of future results are inherently uncertain, as
they are subject to numerous factors or events beyond the control of the parties
and their advisors.

                                       37
<PAGE>   47

Accordingly, these projections and analyses are not necessarily indicative of
actual future results, which may be significantly more or less favorable than
suggested by those analyses. Therefore, neither Johns Manville nor J.P. Morgan
nor any other person assumes responsibility if future results are materially
different from those forecasted.

     The projections furnished to J.P. Morgan were prepared by Johns Manville's
management. Johns Manville does not publicly disclose internal management
projections of the type provided to J.P. Morgan in connection with J.P. Morgan's
analysis of the proposed merger, and such projections were not prepared with a
view toward public disclosure. These projections were based on numerous
variables and assumptions that are inherently uncertain and may be beyond the
control of management, including, without limitation, factors related to general
economic and competitive conditions and prevailing interest rates. Accordingly,
actual results could vary significantly from those set forth in such
projections.

     As a part of its investment banking business, J.P. Morgan and its
affiliates are continually engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, investments for passive
and control purposes, negotiated underwritings, secondary distribution of listed
and unlisted securities, private placements, and valuations for estate,

     In arriving at its opinion, J.P. Morgan reviewed, among other things:

     - the merger agreement and tax agreement;

     - the audited financial statements of Johns Manville and the Manville Trust
       for the fiscal year ended December 31, 1999, and their unaudited
       financial statements for the period ended March 31, 2000;

     - certain internal financial analyses and forecasts prepared by management;

     - certain information regarding Manville Trust income projections and
       forecasted amounts of asbestos injury claims filed and settled provided
       to Johns Manville by the Manville Trust; and

     - the voting agreement, between HB Merger LLC and the Manville Trust.

     In addition, J.P. Morgan held discussions with certain members of Johns
Manville management and the Manville Trust with respect to certain aspects of
the tax agreement, and the past and current business operations of Johns
Manville and the Manville Trust, the financial condition and future prospects
and operations of Johns Manville and the Manville Trust, the potential effects
of the tax agreement on the financial condition and future prospects of Johns
Manville and the Manville Trust, and certain other matters J.P. Morgan believed
necessary or appropriate to its inquiry. J.P. Morgan also held discussions with
certain members of Johns Manville management and the Hicks, Muse/Bear Stearns
group with respect to certain aspects of the proposed merger, and certain other
matters J.P. Morgan believed necessary or appropriate to its inquiry. J.P.
Morgan reviewed such other financial studies and analyses and considered such
other information as J.P. Morgan deemed appropriate for the purposes of its
opinion.

     In giving its opinion, J.P. Morgan relied upon and assumed, without
independent verification, the accuracy and completeness of all information that
was publicly available or was furnished to J.P. Morgan by Johns Manville, the
Manville Trust or the Hicks, Muse/Bear Stearns group or otherwise reviewed by
J.P. Morgan. J.P. Morgan has not assumed any responsibility or liability
therefor. J.P. Morgan has not conducted any valuation or appraisal of any assets
or liabilities (other than its valuation analysis of Johns Manville's tax
liability to the Manville Trust), nor were any such valuations or appraisals
provided to J.P. Morgan. In relying on financial analyses and forecasts provided
to J.P. Morgan, J.P. Morgan assumed that they were reasonably prepared based on
assumptions reflecting the best currently available estimates and judgments by
management as to the expected future results of operations and financial
condition of Johns Manville or the Manville Trust to which such analyses or
forecasts relate. J.P. Morgan assumed that the proposed merger will have the tax
consequences described in discussions with, and materials furnished to, it and
that the Manville Trust will not be subject to state income tax obligations and
will be taxed for federal income tax purposes at a rate of 15%. J.P. Morgan
further assumed that the other transactions contemplated by the tax agreement
and the merger will be consummated as described in such agreements. J.P. Morgan
relied as to all legal matters relevant to rendering its opinion upon the advice
of counsel.

     J.P. Morgan indicated that it based its opinion on economic, market and
other conditions as in effect on, and the information made available to J.P.
Morgan, as of the June 22, 2000. Subsequent developments may affect J.P.
Morgan's opinion and J.P. Morgan does not have any obligation to update, revise,
or reaffirm its opinion.

     J.P. Morgan indicated that it employed generally accepted valuation methods
in reaching its opinion. The following is a summary of the material financial
analyses performed by J.P. Morgan in connection with its opinion.

     J.P. Morgan primarily relied on discounted cash flow valuation to evaluate
Johns Manville's tax liability to the Manville Trust. J.P. Morgan analyzed
potential future taxes based on projections received by Johns Manville from the
Manville Trust, including expected asbestos claim filings, claim inflation,
expected claim settlements and Manville Trust operating expenses, among other
information. Potential future taxes were determined by utilizing a range of
investment returns achieved by the Manville Trust from 5.0% to 8.5% annually.
The implied value of Johns Manville's liability for income taxes of the Trust
ranged from $74 million to $262 million.

OPINION OF GOLDMAN SACHS

     On June 22, 2000, Goldman Sachs, financial advisor to the Manville Trust,
rendered its oral opinion to the board of trustees of the Manville Trust, which
was subsequently confirmed by the written opinion of Goldman Sachs, dated June
22, 2000, that, as of that date, and based upon and subject to the various
qualifications and assumptions described in the opinion, the consideration to be
received by the Manville Trust in exchange for its shares of Johns Manville
common stock pursuant to the exchange agreement and the merger agreement was
fair from a financial point of view to the Manville Trust. The consideration to
be received by the Manville Trust consists of: (1) surviving corporation common
stock and surviving corporation junior preferred stock to be received by the
Manville Trust in exchange for its shares of class TM preferred stock pursuant
to the exchange agreement and the merger agreement and (2) the common stock
merger consideration to be received by the Manville Trust in exchange for its
shares of Johns Manville common stock pursuant to the merger agreement. Goldman
Sachs did not opine on the fairness of the consideration to be received by any
other holders of shares of Johns Manville common stock.

     The full text of the written opinion of Goldman Sachs, dated June 22, 2000,
which sets forth the assumptions made, procedures followed, matters considered,
and limitations on the review undertaken in connection with the opinion, is
attached to this proxy statement/prospectus as Appendix E and is incorporated
herein by reference. The opinion should be read in its entirety.

     In connection with its opinion, Goldman Sachs reviewed, among other things:

     - the merger agreement and the exhibits and annexes thereto, including the
       certificates of designation relating to the class TM preferred stock, the
       pay-in-kind preferred stock, and the surviving corporation junior
       preferred stock, and the stockholders agreement relating to the surviving
       corporation;

     - the tax matters agreement;

     - the trust voting agreement;

     - Annual Reports to Stockholders and Annual Reports on Form 10-K of Johns
       Manville for the five years ended December 31, 1999;

     - certain interim reports to stockholders and Quarterly Reports on Form
       10-Q of Johns Manville; and

     - certain internal financial analyses and forecasts for Johns Manville
       prepared by Johns Manville's management.

     In addition, Goldman Sachs:

     - held discussions with members of the senior management of Johns Manville
       regarding their assessment of the past and current business operations
       and financial condition, and future prospects of Johns Manville;

     - reviewed the reported price and trading activity of Johns Manville common
       stock;

     - compared certain financial and stock market information for Johns
       Manville with similar information for certain other companies, the
       securities of which are publicly traded;

     - reviewed the financial terms of certain recent business combinations in
       the building products industry specifically, and in other industries
       generally; and

     - performed other studies and analyses as Goldman Sachs considered
       appropriate.

     Goldman Sachs relied upon the accuracy and completeness of all of the
financial and other information reviewed by it and assumed their accuracy and
completeness for purposes of rendering its opinion. Goldman Sachs took into
account, with the consent of the board of trustees of the Manville Trust,
management's assessment of the risks and uncertainties associated with Johns
Manville achieving
                                       40
<PAGE>   50

management's forecasts in the amounts and at the times indicated. In addition,
Goldman Sachs did not make an independent evaluation or appraisal of the assets
and liabilities of Johns Manville and Goldman Sachs was not furnished with any
such evaluation or appraisal. In connection with its consideration of the
proposed transaction, Goldman Sachs relied upon the advice the Manville Trust
received from its legal counsel and tax advisors as to all legal and tax
matters. The opinion of Goldman Sachs was provided for the information and
assistance of the board of trustees of the Manville Trust in connection with its
consideration of the exchange agreement and the merger agreement. The Goldman
Sachs opinion was not provided for the information or assistance of either the
Johns Manville board or other shareholders of Johns Manville, nor does it
constitute a recommendation as to how the Manville Trust or any other holder of
Johns Manville common stock should vote with respect to the proposed merger. The
Goldman Sachs opinion does not address the treatment of the Manville Trust and
the other stockholders of Johns Manville as among themselves. Goldman Sachs did
not express any opinion as to the impact of the merger on the solvency or
viability of the surviving corporation or the ability of the surviving
corporation to pay its obligations when they become due.

     In rendering its opinion, Goldman Sachs took into account the process in
which a significant number of third parties were contacted during the review in
1999 of strategic alternatives regarding their interest in pursuing a business
combination with Johns Manville and the results of that process. Goldman Sachs
also noted that during the exclusivity period in which negotiations were being
held with Hicks, Muse and Bear Stearns, a third party indicated an interest in
acquiring Johns Manville at a price of $15.50 in cash per share of Johns
Manville common stock. Goldman Sachs indicated that it understood that, among
other factors, given the exclusivity assurances required by Hicks, Muse and Bear
Stearns, Johns Manville determined to continue its exclusivity relationship with
Hicks, Muse and Bear Stearns. Goldman Sachs noted that pursuant to the terms of
the tax agreement, the Manville Trust will be paid $90 million in cash in
consideration for the Manville Trust's agreement to pay all applicable taxes
attributable to the income and gains of the designated settlement fund portion
of the Manville Trust for all periods beginning on or after the time the $90
million payment is made. The $90 million payment and the other terms related
thereto were determined based on extensive arm's length negotiations between
Johns Manville and the Manville Trust, in which Goldman Sachs participated.
Goldman Sachs did not opine on terms of this tax settlement in rendering its
opinion.

     Goldman Sachs did not express a view as to the prices at which actual
transactions involving the pay-in-kind preferred stock will occur, which prices
will be dependent upon and fluctuate with dividend rates generally, market
conditions, general economic conditions, the financial condition and prospects
of the surviving corporation, and other factors which generally influence the
price of similar securities. Goldman Sachs noted that the Manville Trust agreed
not to transfer the shares of pay-in-kind preferred stock to be received by the
Manville Trust for a period of up to 180 days following the closing of the
merger and that, thereafter, given the terms of the pay-in-kind preferred stock
and the percentage of that issue owned by the Manville Trust, it is very likely
that those shares will be highly illiquid.

     The following is a summary of the material financial analyses reviewed by
Goldman Sachs and used in connection with providing its opinion to the board of
trustees of the Manville Trust on June 22, 2000. It does not purport to be a
complete description of the analyses performed by Goldman Sachs. The order of
analyses described, and the results of those analyses, do not represent relative
importance or weight given to those analyses by Goldman Sachs. Except as
otherwise noted, the following quantitative information, to the extent that it
is based on market data, is based on market data as it existed on or before June
22, 2000, and is not necessarily indicative of current market conditions. As
used in the following summary, "enterprise value" means equity value plus debt
less cash; "P/E" means the ratio of price to earnings per share; "EBITDA" means
earnings before interest, taxes, depreciation and amortization; "EBIT" means
earnings before interest and taxes; "LTM" means latest twelve months; and "EPS"
means earnings per share.

     THE SUMMARY INCLUDES INFORMATION PRESENTED IN TABULAR FORMAT. THESE TABLES
SHOULD BE READ TOGETHER WITH THE TEXT OF EACH SUMMARY.

     Implied Transaction Premiums and Multiples. Goldman Sachs reviewed certain
implied transaction premiums and multiples using a range of implied values of
$14.19 to $15.63 for the total consideration being offered for each share of
Johns Manville common stock pursuant to the merger agreement. This range of
implied per share value reflects the cash component of $13.625 plus a range of
$0.565 to $2.00 for the implied value of the preferred stock component of the
total consideration being offered for each share of Johns Manville common stock.
The range of implied values of the preferred stock component was derived using
implied yields based on discount rates ranging from 13.0% to 26.0%. Goldman
Sachs noted that the range of implied per share values represents a premium of
15.0% to 26.0% compared to the closing price of Johns Manville common stock on
June 20, 2000.

     Goldman Sachs also calculated the implied transaction premiums of the same
range of implied per share values as compared with the following historical
prices of Johns Manville common stock:

<TABLE>

52-week high ($14.813 on August 26, 1999)                -4% to 5%
</TABLE>

     Using the range of implied per share value of $14.19 to $15.63, Goldman
Sachs calculated the enterprise value of Johns Manville to be in the range of
$2.642 billion to $2.849 billion. Goldman Sachs then calculated the enterprise
value of Johns Manville as a levered multiple of revenue, EBITDA and EBIT for
each of the following periods:

     - calendar year 1999;

     - LTM as of March 31, 2000; and

     - calendar year 2000, based on Johns Manville management's estimates and
       adjusted to account for restructuring charges of $11.9 million.

         The Stanley Works
         USG Corporation

In its analysis, Goldman Sachs used closing market prices on June 20, 2000 and
other publicly available information. Goldman Sachs calculated the P/E multiples
of Johns Manville and the selected companies for calendar years 2000 and 2001
using estimates of 2000 and 2001 EPS based on the medians of the IBES estimates
provided as of June 20, 2000. Goldman Sachs calculated and compared each
company's (i) closing stock price on June 20, 2000 as a percent of its preceding
52-week high, (ii) enterprise value as a multiple of its LTM EBITDA as of March
31, 2000 and of its estimated EBITDA for calendar year 2000 and (iii) estimated
2000 and 2001 P/E multiples. The results of this analysis indicated the

     Present Value of Potential Future Share Prices -- Sensitivity
Analysis. Goldman Sachs calculated the present value of the potential future
price per share for Johns Manville common stock on June 30, 2001. Goldman Sachs
used a range of P/E multiples and four different assumed EPS estimates for
calendar year 2001 to calculate the potential future price per share. Goldman
Sachs noted that the IBES 2001 EPS estimate is $1.86 and Johns Manville
management's 2001 EPS estimate is $1.92. The result of this analysis is as
follows:

     Using the range of potential share prices on June 30, 2001, for each

     Discounted Cash Flow Analysis. Goldman Sachs conducted discounted cash flow
analyses of two scenarios. The first scenario used management's projections. The
second scenario used management's projections, as modified to reflect a
"downside case" involving a downturn in the economy in calendar year 2001. For
both scenarios, Goldman Sachs calculated and analyzed the sensitivity of the
implied equity value for Johns Manville on a per share basis based on the
following information:

     - Johns Manville's net debt of $415 million as of May 31, 2000;

     - 148.7 million primary shares of Johns Manville common stock outstanding;
       and

     - 6.7 million options to purchase Johns Manville common stock with a
       weighted average exercise price of $12.49.

     Goldman Sachs calculated a range of implied equity values for Johns
Manville on a per share basis by discounting projected cash flows for the fourth
quarter of 2000 and for the period of 2001 to 2004 using a terminal multiple of
EBITDA ranging from 5.25x to 6.25x in calendar year 2004 at discount rates
ranging

                                       44
<PAGE>   54

from 10.0% to 14.0%. This analysis showed the following ranges for the implied
equity value per share of Johns Manville common stock:

     Using a 5.75x terminal EBITDA multiple and a 12.0% discount rate, Goldman
Sachs performed a sensitivity analysis to consider the impact of variances in
Johns Manville's sales growth and EBIT margins for the period of 2000 to 2004 on
its implied equity value per share. This analysis showed that, with a variance
in sales growth during the entire forecast period ranging from -5.0% to 0.0% per
year and a variance in EBIT margin during the entire forecast period ranging
from -5.0% to 0.0% per year, the ranges for the implied equity value of Johns
Manville common stock were as follows:

     Using a 12.0% discount rate, Goldman Sachs performed a sensitivity analysis
to consider the impact of variances in terminal multiples of EBITDA and
projected exit EBITDA margins in calendar year 2004, which provide a basis for
calculating terminal value, on the implied equity value per share of Johns
Manville common stock. This analysis showed that, with a variance in terminal
EBITDA multiples ranging from 5.25x to 6.25x and a variance in exit EBITDA
margin ranging from 18.0% to 26.5%, the ranges for the implied equity value per
share of Johns Manville common stock would be as follows:

LBO Return Analysis.

     Goldman Sachs conducted leveraged buyout return analyses using the capital
structure proposed by Hicks, Muse and Bear Stearns and a range of illustrative
exit multiples of estimated EBITDA in each of the calendar years 2002, 2003 and
2004. The terminal EBITDA multiples used ranged from 5.25x to 6.25x. For
purposes of analysis, Goldman Sachs made the following additional assumptions:

     - all options, deferred shares and deferred share equivalents are
       liquidated for cash;

     - the interest rates are as follows: Term Loan A, 9.75%; Term Loan B,
       10.25%; Term Loan C, 10.50%; revolving credit loan, 10.00%; senior
       subordinated debt, 13.00%; and pay-in-kind preferred stock, 13.00%;

     - transaction-related fees and expenses of approximately $160 million; and

     - recapitalization accounting applies to the proposed transaction.

Goldman Sachs conducted the leveraged buyout return analyses for each of the
projection scenarios provided by Johns Manville's management.

     The analyses showed the following ranges of compounded annual return on
investment to the equity holders of the surviving corporation:

     Goldman Sachs also performed a sensitivity analysis to consider the impact
of variances in terminal multiples of EBITDA in calendar year 2004 and projected
exit EBITDA margins ranging from 18.0% to 26.5%. This analysis showed that the
ranges of compounded annual return on investment to the equity holders of the
surviving corporation would be as follows:

     The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. Selecting
portions of the analyses or of the summary set forth above, without considering
the analyses as a whole, could create an incomplete view of the processes
underlying the opinion of Goldman Sachs. In arriving at its opinion, Goldman
Sachs considered the results of all of its analyses and did not attribute any
particular weight to any factor or analysis considered by it; rather, Goldman
Sachs made its determination as to fairness on the basis of its experience and
professional judgment after considering the results of all of its analyses. No
company used in the above analyses as a comparison is directly comparable to
Johns Manville and no transaction used is directly comparable to the proposed
merger.

     Goldman Sachs prepared these analyses solely for purposes of providing an
opinion to the board of trustees of the Manville Trust as to the fairness to the
Manville Trust, from a financial point of view, of the consideration to be
received by the Manville Trust for its shares of Johns Manville common stock
pursuant to the exchange agreement and the merger agreement. These analyses do
not purport to be appraisals, nor do they necessarily reflect the prices at
which businesses or securities actually may be sold. Analyses based upon
forecasts of future results are not necessarily indicative of actual future
results, which may be significantly more or less favorable than suggested by
these analyses. Because these analyses are inherently subject to uncertainty and
are based upon numerous factors or events beyond the control of the parties or
their respective advisors, none of Johns Manville, the Manville Trust or Goldman
Sachs assumes responsibility if future results are materially different from
those forecasted. As described above, the opinion of Goldman Sachs to the board
of trustees of the Manville Trust was one of many factors taken into
consideration by the board of trustees of the Manville Trust in making its
determination to approve the merger agreement.

     Goldman Sachs, as part of its investment banking business, is continually
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, negotiated underwritings, competitive biddings,
secondary distributions of listed and unlisted securities, private placements
and valuations for estate, corporate and other purposes. Goldman Sachs is
familiar with the Manville Trust, having provided various investment banking
services from time to time, including having been engaged by the Manville Trust
in 1992 to assist it on an ongoing basis in its analysis, consideration and
negotiation of various financial alternatives available to it with respect to
the Manville Trust's ownership interest in Johns Manville. In connection with
that engagement, Goldman Sachs acted as financial advisor to the Manville Trust
in regard to the profit sharing exchange agreement, dated as of October 25,
1995, between Johns Manville and the Manville Trust and, on a periodic basis,
Goldman Sachs participated in a review of strategic alternatives by the Manville
Trust with respect to its ownership interest in Johns Manville. Goldman Sachs
also acted as the Manville Trust's financial advisor in connection with, and
participated in certain of the negotiations leading to, the exchange agreement
and the merger agreement. Goldman Sachs is also familiar with Johns Manville,
having acted as financial advisor to the Special Advisor to the United States
Bankruptcy Court in evaluating the assets and liabilities of Johns Manville and
the Manville Trust in 1990; and having acted in 1994 as lead underwriter on the
$400 million secondary offering by the Manville Trust of 10.87% Notes due
December 2004, for Schuller International Group, Inc., a wholly owned subsidiary
of Johns Manville. Goldman Sachs noted that from time to time it has provided
numerous investment banking services to Hicks, Muse and several of its portfolio
companies and may provide investment banking services to Hicks, Muse or Bear
Stearns and their respective subsidiaries and affiliates in the future. Goldman
Sachs provides a full range of financial advisory and securities services

                                       46
<PAGE>   56

and, in the course of its normal trading activities, Goldman Sachs may from time
to time effect transactions and hold positions in securities, including
derivative securities, of Johns Manville for the account of Goldman Sachs and
the accounts of its customers.

     Pursuant to a letter agreement dated January 24, 1999 between the Manville
Trust and Goldman Sachs, the Manville Trust engaged Goldman Sachs to act as its
exclusive financial advisor in connection with the possible sale of all or a
portion of the Manville Trust's equity interest in Johns Manville. Pursuant to
the terms of this letter, Goldman Sachs has received a retainer fee aggregating
$900,000. If the proposed merger is consummated, the Manville Trust will pay
Goldman Sachs a transaction fee in a cash amount equal to 0.75% of the aggregate
value in cash, securities and other assets payable to or received by the
Manville Trust in respect of its equity interest in Johns Manville, including
the value of securities of the surviving corporation that are retained by the
Manville Trust pursuant to the merger agreement and the exchange agreement.
Pursuant to the terms of the letter agreement the retainer fee will be credited
against the transaction fee.

     In addition, the Manville Trust agreed to reimburse Goldman Sachs
periodically, upon request, and upon consummation of the merger or upon
termination of its services pursuant to the letter agreement, for its reasonable
out-of-pocket expenses, including the reasonable fees and disbursements of
Goldman Sachs' attorneys, plus any sales, use or similar taxes, including
additions to such taxes, if any, arising in connection with any matter referred
to in the letter. The Manville Trust also agreed to indemnify Goldman Sachs and
certain related persons against certain liabilities in connection with its
engagement, including liabilities under the federal securities laws. In
addition, pursuant to a separate letter agreement, dated January 24, 1999,
between Johns Manville and Goldman Sachs, Johns Manville also agreed to
indemnify Goldman Sachs and certain related persons against certain liabilities
in connection with its engagement by the Manville Trust, including liabilities
under the federal securities laws.

PURPOSE OF THE MERGER; CERTAIN EFFECTS OF THE MERGER

     The principal purpose of the merger is to enable the members of the Hicks,
Muse/Bear Stearns group to own substantially all of the common equity interest
in Johns Manville and afford Johns Manville's stockholders the opportunity to
receive a price for their shares that represents a premium over the market price
at which the shares traded prior to the announcement of the merger. This will be
accomplished by a merger of HB Merger LLC, a newly formed limited liability
company formed by the Hicks, Muse/Bear Stearns group to effect the merger, with
and into Johns Manville, with Johns Manville as the surviving corporation. In
the merger, each share of Johns Manville common stock, (other than a portion of
the shares of common stock held by the Manville Trust and some members of
management which will be retained in the continuing corporation, shares held by
affiliates of HB Merger LLC and other than dissenting stockholders who perfect
appraisal rights) will be converted into the right to receive the merger
consideration of $13.625 in cash plus 0.02 of a share of pay-in-kind preferred
stock.

     The merger will terminate all common equity interest in Johns Manville held
by stockholders other than the members of the Hicks, Muse/Bear Stearns group,
the Manville Trust and some members of Johns Manville management; and these
persons and entities will be the sole beneficiaries of any earnings and growth
of Johns Manville following the merger. Accordingly, Johns Manville stockholders
whose shares will be converted into cash and pay-in-kind preferred stock in the
merger will no longer benefit from any increase in the value of Johns Manville
other than through the value of the pay-in-kind preferred stock.

     Johns Manville's common stock is currently registered under the Securities
Exchange Act of 1934 and is listed for trading on the New York Stock Exchange
under the symbol "JM". Upon the completion of the merger, Johns Manville's
common stock will be delisted from the New York Stock Exchange and registration
of Johns Manville's common stock under the Exchange Act will be terminated. As a
result of the issuance of the pay-in-kind preferred stock in the merger, the
pay-in-kind stock will be registered under the Exchange Act following the merger
unless and until its registration is terminated thereunder.

PLANS FOR SURVIVING CORPORATION AFTER THE MERGER

     It is expected that following the merger the business and operations of
Johns Manville as the surviving corporation will, except as set forth in this
proxy statement/prospectus, be conducted substantially as they are currently
conducted. Except for the merger or as contemplated in the merger agreement or
in this proxy statement/prospectus, none of Johns Manville, HB Finance LLC or HB
Merger LLC have any present plans relating to or that would result in the
following:

     - an extraordinary corporate transaction such as a merger, reorganization
       or liquidation involving Johns Manville, or a sale or other transfer of a
       material amount of assets of Johns Manville; or

     - any changes in the management of Johns Manville; or

     - any changes in Johns Manville's corporate structure or business (for a
       further description of restrictions as to such actions see "Other
       Relevant Agreements -- Stockholder Agreement").

     Following the merger, there will be some significant changes in Johns
Manville, including the following:

     - Johns Manville will no longer pay quarterly cash dividends on the
       surviving corporation common stock;

     - Johns Manville will have substantially more debt than it had prior to the
       merger (see "Risk Factors" and "Selected and Historical Pro Forma
       Financial Data"); and

     - persons associated with Hicks, Muse and Bear Stearns will have the
       ability to elect a majority of the board of directors of Johns Manville
       (see "Other Relevant Agreements -- the Stockholders Agreement").

     In addition, after the merger, Johns Manville will continue to evaluate its
business and operations and make any changes that it deems appropriate.

INTERESTS IN THE MERGER THAT DIFFER FROM YOUR INTERESTS

     In considering the recommendation of the Johns Manville board with respect
to the merger, Johns Manville stockholders should be aware that some of its
directors and executive officers have interests in the merger that may be
different from or in addition to your interests as a stockholder. The special
committee and the Johns Manville board were aware of these actual and potential
conflicts of interest when they made their decision to approve the merger
agreement and the amendment to the restated certificate of incorporation and
declared that the merger agreement and the amendment to the certificate of
incorporation are advisable.

     Continued Common Equity Participation by Manville Trust and
Management. Following approval by stockholders of the proposed amendment to the
restated certificate of incorporation and prior to the closing under the merger
agreement, the Manville Trust and some members of Johns Manville management,
including Thomas L. Caltrider, Kenneth L. Jensen and Harvey L. Perry, Jr., will
exchange a portion of their shares of Johns Manville common stock for shares of
class TM preferred stock. In the merger, the shares of class TM preferred stock
will be converted into shares of common stock of the surviving corporation and
shares of junior preferred stock of the surviving corporation, rather than the
common stock merger consideration of $13.625 in cash and 0.02 of a share of the
pay-in-kind preferred stock. Surviving corporation common stock and junior
preferred stock will not be available to Johns Manville's public stockholders.

     Tax Payment to the Manville Trust. In connection with the merger, Johns
Manville is making a cash payment to the Manville Trust of $90,000,000 under the
tax agreement, in which, among other things, the parties agreed that the
Manville Trust will assume Johns Manville's liability for income taxes of the
Manville Trust in return for the cash payment. For a further description of the
tax agreement see "Other Relevant Agreements -- Tax Agreement".
                                       48

     Treatment of Equity Awards. Upon the consummation of the merger, each
outstanding stock option and stock appreciation right will be cancelled in
exchange for a payment of cash in an amount equal to the excess of the greater
of $15.625 and the highest fair market value of the common stock for the 60-day
period prior to the merger over the exercise price of such option or grant price
of such stock appreciation right, multiplied by the number of shares subject to
such option or such stock appreciation right, whether or not previously vested
or exercisable. Upon the consummation of the merger, each outstanding share of
deferred stock will be cancelled in exchange for a payment of cash in an amount
equal to the greater of $15.625 or the highest fair market value of the common
stock for the 60-day period prior to the merger. Mr. Henry has agreed, pursuant
to his employment agreement, to receive, and some other members of management,
including Messrs. Caltrider, Jensen and Perry, have elected to receive, in lieu
of some or all the amounts described above, that number of deferred shares of
surviving corporation common stock and surviving corporation junior preferred
stock having an aggregate value of $15.625 per share (less applicable employment
withholding taxes) equal to the quotient of (i) the cash that would otherwise
have been payable to such officer in lieu of his cancelled Johns Manville stock
options and deferred shares and (ii) 15.625. The following table sets forth the
estimated value of the equity awards held by the executive officers of Johns
Manville, based on an assumed price of $15.625 per share, and their estimated
equity investments in the surviving corporation (other than with respect to
shares of pay-in-kind preferred stock):

     Treatment of Deferred Compensation. Upon the consummation of the merger,
each unit under Johns Manville's deferred compensation plans deemed invested in
assets other than Johns Manville common stock will be paid in cash at the value
of that unit. Each unit under these plans deemed to be invested in Johns
Manville common stock will be settled in cash at a value of $15.625 per share.
Some members of management, including Messrs. Henry, Caltrider, Jensen and
Perry, will be entitled to receive, in lieu of $15.625 per share in cash,
deferred shares of surviving corporation common stock and surviving corporation
junior preferred stock equal in value to such cash payment.

     Employment Agreement with Mr. Henry. Mr. Henry has entered into a letter
agreement which provides that, upon the consummation of the merger, HB Merger
LLC will cause the surviving corporation to enter into an employment agreement
which will replace Mr. Henry's current Transition and Retirement Agreement. The
new agreement provides that Mr. Henry will serve as President and CEO of the
surviving corporation for a term of three years. Mr. Henry will receive a base
salary of $725,000 per year, a target bonus equal to 100% of salary, a signing
bonus of $4,300,000 and a supplemental deferred signing bonus of $1,056,250,
which will be deemed invested in deferred shares of surviving corporation common
stock and surviving corporation junior preferred stock. Mr. Henry will also
become immediately eligible to receive a retirement benefit of $4,864,605.

     In addition, as soon as practicable following the consummation of the
merger, Mr. Henry will be granted stock options to purchase a number of shares
of surviving corporation common stock and surviving corporation junior preferred
stock representing, in the aggregate, 200% of the total number of shares he will
own in the surviving corporation including those deferred shares he receives as
a result of the rollover of equity awards discussed in the preceding paragraph
(currently expected to be between 384,000 and 640,000 options), whose options
will have an exercise price of $15.625 per share and will vest with respect to
50% of the shares subject to the option over a period of three years, and with
respect to the remaining 50%, based on the achievement of certain operating
performance targets. Upon the consummation of the merger, $3,000,000 to
$5,000,000 in value of Mr. Henry's supplemental deferred signing bonus, his
deferral account invested in deemed shares of Johns Manville and, if necessary,
his other outstanding equity interests will be rolled over and assumed by the
surviving corporation as deemed shares of surviving corporation common stock and
surviving corporation junior preferred stock.

     If, during the 36 month employment period, Mr. Henry's employment is
terminated by the surviving corporation without "cause" or by Mr. Henry for
"good reason," which includes, for example, a material reduction in his
responsibility, authority or duties, he will be entitled to receive a cash
amount equal to the sum of three times his base salary and his target bonus, the
target annual bonus for the year of termination, 36 months of continued welfare
benefits, fringe benefits and perquisites and $50,000 of outplacement services.
In addition, a "gross-up" payment to compensate Mr. Henry for any "golden
parachute" excise tax is also provided.

     Assuming current salary and bonus information remains in effect, if Mr.
Henry's employment is terminated following the merger for the reasons described
above, the approximate value of the severance

                                       50
<PAGE>   60

payments due under his employment agreement, not including any payments that may
be made with respect to any excise tax, would be $5,280,417.

     Employment Agreement for Messrs. Caltrider, Klocko, Jensen and
Perry. Messrs. Caltrider, Klocko, Jensen and Perry currently have employment
agreements with Johns Manville which provide for certain benefits upon a
termination of employment following a change in control of Johns Manville. Under
the terms of the original agreements, the merger constitutes a change in control
of Johns Manville.

     Generally, the terms of the original agreements provide that if the
executive's employment is terminated following a change in control without
"cause" or by the executive for "good reason" (which includes, for example, a
material adverse change in the nature or scope of the executive's
responsibility, authority or duties, including by reason of a substantial change
in the character or scope of Johns Manville's operations), the executive will be
entitled to receive a cash amount equal to three times the sum of the
executive's then current base salary and target annual bonus, two years'
additional credit in certain cases under Johns Manville's Supplemental Pension
Plan, 36 months of continued welfare benefits and 24 months of continued
perquisites. In addition, a "gross-up" payment to compensate the executive for
any "golden parachute" excise tax is also provided.

     As part of the merger agreement negotiations, HB Merger LLC requested that
the agreements with Messrs. Caltrider, Jensen and Perry and other members of
management be amended. In particular, HB Merger LLC requested that each
executive agree to modify and narrow the applicable definition of "good reason"
and modify the definition of change in control to exclude the merger. On June
22, 2000, Messrs. Caltrider, Jensen and Perry each agreed to amend his
employment agreement, effective as of the consummation of the merger. In
general, the amendments confirmed the executives' benefits, and in some cases
reduced the executives' ability to receive such benefits. The amendments
provide, among other things:

     - that stock options of the surviving corporation will be granted to
       Messrs. Caltrider, Jensen and Perry as soon as possible following the
       date of the consummation of the merger in the following numbers: Mr.
       Caltrider 128,000 options, Mr. Jensen 128,000 options and Mr. Perry
       192,000 options;

     - a more narrow definition of "good reason" which excludes from such term
       any assignment of the executive to a management position with significant
       responsibilities, authorities and duties which is appropriate based on
       the executive's skills, training and experience or a temporary assignment
       of not more than twelve months; and

     - that the merger will not constitute a change in control of Johns Manville
       for purposes of each executive's agreement.

     Notwithstanding these amendments, each of Messrs. Caltrider, Jensen and
Perry will nonetheless be eligible to receive those payments and benefits to
which he would otherwise be entitled upon a termination by Johns Manville
without "cause" or by the executive for "good reason," if, during the 18-month
period following the consummation of the merger, the executive's employment is
terminated without "cause" or the executive terminates his employment for "good
reason" (under the revised definition) or terminates employment within a 60 day
period beginning on the first anniversary of the date he was given a temporary
position from which he was not timely restored.

     Assuming current salary and bonus information remains in effect, if the
employment of each of the executive officers is immediately terminated by Johns
Manville without "cause" or by the executive for "good reason" following the
merger, the approximate value of the severance payments due under the employment
agreement to Messrs. Caltrider, Klocko, Jensen and Perry, including value
attributable to additional retirement plan credit and continuation of welfare
benefits and perquisites but not including any payments that may be made with
respect to any excise tax, would be $1,809,333, $1,336,875, $1,455,709 and
$1,717,334, respectively.

     Indemnification of Directors. The merger agreement provides that the
surviving corporation and its subsidiaries will indemnify and hold harmless, to
the fullest extent permitted by law, each of the present
                                       51
<PAGE>   61

and former employees, agents, officers and directors of Johns Manville or its
subsidiaries, against any claim, liability, loss, damage, cost or expense
arising out of actions or omissions occurring at or prior to the effective time
of the merger. In addition, for a period of at least six years following the
effective time, the surviving corporation will maintain in effect the
indemnification provisions contained in Johns Manville's existing articles of
incorporation and by-laws and certain additional provisions identified in the
merger agreement.

     For a period of at least six years after the effective time of the merger,
the surviving corporation will maintain in effect directors' and officers'
liability insurance equivalent in all material respects to existing policies.
However, the surviving corporation will not be required to pay annual premiums
for the directors' and officers' insurance in excess of 200% of the annual
premiums paid as of the date of the merger agreement, but in that case will
purchase as much coverage as possible for that amount.

REGULATORY MATTERS

     Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended,
and the related rules, the merger may not be completed until notifications have
been given, certain information has been furnished to the Federal Trade
Commission or the United States Department of Justice and specified waiting
period requirements have been satisfied.

     Johns Manville conducts operations in a number of jurisdictions where other
regulatory filings or approvals may be required or advisable in connection with
the completion of the merger. Johns Manville is currently in the process of
reviewing whether other filings or approvals may be required or desirable in
these other jurisdictions. We recognize that some of these filings may not be
completed before the closing, and that some of these approvals, which are not as
a matter of practice required to be obtained prior to effectiveness of a merger
transaction, may not be obtained prior to the closing.

SOURCE AND AMOUNT OF FUNDS

     In order to finance the merger HB Finance LLC has arranged for equity
commitments from affiliates of Hicks, Muse and Bear Stearns in an aggregate
amount of $500,000,000, a senior secured credit facility with Bear Stearns
Corporate Lending Inc. in an aggregate amount of $1,750,000,000 and a bridge
facility with Bear Stearns Corporate Lending in an aggregate amount of
$600,000,000 in the event that Johns Manville is unable to issue, prior to the
closing of the merger agreement, an equivalent amount of senior subordinated
notes. In addition, the Manville Trust will invest $50,000,000 of its existing
equity of Johns Manville in the surviving corporation by converting its class TM
preferred stock into common stock and junior preferred stock of the surviving
corporation (based on a price per share of Johns Manville common stock of
$15.625), and some members of Johns Manville's management will invest a total of
approximately $15,000,000 in the aggregate, through the conversion of the class
TM preferred stock they will receive pursuant to the exchange agreement into
common stock and junior preferred stock of the surviving corporation.

  Expenses

     The following table sets forth the estimated fees and expenses incurred and
to be incurred by HB Merger LLC and HB Finance LLC in connection with the
merger. These fees are the primary responsibility of HB Merger LLC and HB
Finance LLC except that, upon completion of the merger, the surviving
corporation will become responsible for the fees and expenses of HB Merger LLC
by operation of law. In addition, upon termination of the merger agreement under
some circumstances, Johns Manville

                                       52
<PAGE>   62

is obligated to reimburse HB Merger LLC and HB Finance LLC for these expenses up
to $12.5 million. See "The Merger Agreement -- Fees and Expenses."

  Equity Commitment Letters

     Pursuant to equity commitment letters dated June 22, 2000, Bear Stearns
Merchant Fund Corp. and HMTF Bridge Partners, L.P., an affiliate of Hicks, Muse,
have committed to provide cash contributions of equity to Johns Manville in
connection with the merger in the amounts of $150,000,000 and $350,000,000,
respectively. Each party's equity commitment is subject to satisfaction of
certain conditions precedent.

  Senior Secured Credit Facilities

     In order to finance the merger, it is contemplated that a subsidiary of
Johns Manville, as borrower, will enter into a senior secured credit facility
with Bear Stearns Corporate Lending Inc. for $1,750,000,000 comprised of a
$500,000,000 tranche A term loan, a $650,000,000 tranche B term loan, a
$300,000,000 tranche C term loan and a revolving credit commitment of
$300,000,000. A portion of the revolving credit facility in an amount to be
agreed will be available through the issuance of letters of credit.
Additionally, a portion of the revolving credit facility may be made available
in foreign currencies.

     The tranche A term loan is repayable in semi-annual installments in amounts
to be agreed upon and is due and payable in full six and one-half years after
the closing date of the loan. The tranche B term loan is repayable in
semi-annual installments in amounts to be agreed upon and is due and payable in
full seven and one-half years after the closing date of the loan. The tranche C
term loan is repayable in semi-annual installments in amounts to be agreed upon
and is due and payable in full eight and one-half years after the closing date
of the loan. The revolving credit commitment terminates six and one-half years
after the closing date of the loan.

     The borrower will have the option to prepay any loan at any time in whole
or in part, without the payment of any premium or penalty. At the borrower's
option, the revolving credit commitment may be permanently reduced, in whole or
in part, at any time.

     The borrower will be required to make mandatory prepayments of the term
loans in respect of 100% of the net proceeds of the incurrence of certain
indebtedness, 50% of the net proceeds of any sale or issuance of equity, 100% of
the net proceeds of any sale or other disposition of assets in excess of an
amount to be agreed, in each case with appropriate exceptions. Additionally, the
borrower will be required to make mandatory prepayments of the term loans in
respect of 50% of excess cash flow for any fiscal year for which the ratio of
consolidated total debt to consolidated EBITDA is equal to or greater than 3.0
to 1.0. Each prepayment of the term loans will be applied to the tranche A term
loan, the tranche B term loan and the tranche C term loan ratably in accordance
with the amounts then outstanding and to each term loan first to the next two
installments due and then ratably to the remaining installments based on the
number of installments then outstanding. At any time while the tranche A term
loan is outstanding, the holders of the tranche B and the tranche C term loans
have the right to refuse all or any portion of the prepayment allocable to the
tranche B and tranche C loans and the amount refused will be applied to the
tranche A term loan.

                                       53
<PAGE>   63

     The loans will bear interest, at the borrower's election, at the eurodollar
rate (the rate at which eurodollar deposits are offered in the interbank
eurodollar market for the relevant interest period of one, two, three, six or
nine or twelve (or if available to all lenders, nine or twelve) months, adjusted
for statutory reserve requirements) or the base rate (defined as the higher of
the administrative agent's publicly announced prime rate in effect at its
principal office in New York and the federal funds effective rate plus 0.5%),
plus the applicable margin. The applicable margins are as follows:

  Tranche A term loans and revolving credit loans:

     - 1.50% for loans bearing interest based on the base rate

     - 2.50% for loans bearing interest based on the eurodollar rate

  Tranche B term loans:

     - 2.00% for loans bearing interest based on the base rate

     - 3.00% for loans bearing interest based on the eurodollar rate

  Tranche C term loans:

     - 2.25% for loans bearing interest based on the base rate

     - 3.25% for loans bearing interest based on the eurodollar rate

     At any time when the borrower is in default in the payment of any amount of
principal due under the senior secured credit facilities, that amount will bear
interest at 2% above the applicable rate. Overdue interest, fees and other
amounts will bear interest at 2% above the rate applicable to base rate loans.
The borrower will pay a commitment fee equal to 0.50% per annum on the average
daily unused amount of the revolving credit commitment. The borrower will pay,
for each letter of credit, a commission to be shared among all lenders
participating in the revolving credit facility and a fronting fee to be paid to
the issuing lender for its own account, in each case at a per annum percentage
to be agreed of the face amount of each letter of credit. The applicable margins
and the commitment fee will be subject to adjustment from and after six months
following the closing date by amounts to be agreed upon based on the ratio of
consolidated total funded debt to consolidated EBITDA.

     The senior secured credit facilities will contain a number of covenants
that restrict the ability of the borrower and its subsidiaries to incur
indebtedness, grant liens, guarantee obligations of other persons, enter into
mergers, consolidations, liquidations and dissolutions, sell or transfer assets,
make dividends and other payments in respect of capital stock, make capital
expenditures, make investments, loans and advances, make optional payments or
modifications of subordinated and other material debt instruments, enter into
transactions with affiliates, enter into sale and leaseback transactions, make
changes in the fiscal year of the borrower and its subsidiaries, enter into
negative pledge agreements, make changes in the line of business or passive
holding company status of Johns Manville or incur or designate other senior
debt.

     The senior secured credit facilities will also contain events of default
including the failure to pay principal when due, nonpayment of interest, fees or
other amounts after a grace period of 5 business days, material inaccuracy of
representations or warranties, violations of covenants (subject, in the case of
certain affirmative covenants to a grace period to be agreed upon),
cross-default to other indebtedness, bankruptcy events, certain ERISA events,
material judgments, actual or asserted invalidity of any guarantee or security
document, subordination provisions or security interests under the senior
secured credit facility documents, and a change of control.

     The obligations under the senior secured credit facilities will be
guaranteed by the direct and indirect present and future domestic subsidiaries
of the borrower and by Johns Manville. The borrower and each of the guarantors
will grant and/or pledge a first priority security interest in substantially all
of their respective tangible and intangible assets (including the capital stock
of, or other equity interests in, each

                                       54
<PAGE>   64

direct domestic subsidiary of the borrower and 65% of the voting capital stock
of, or other equity interests in, each first tier foreign subsidiary of the
borrower), other than leasehold interests in real property and those assets as
to which the syndication agent determines that the costs of obtaining a security
interest are excessive in relation to the value of the security to be afforded
thereby.

     The availability of the senior secured credit facilities is conditioned on
customary conditions including the following conditions precedent having
occurred on or before the closing date of the merger:

     - The absence of any event, development, condition or circumstance that has
       had or could reasonably be expected to have a material adverse effect on
       the merger or on the business, assets, property, condition (financial or
       otherwise), results of operations or prospects of Johns Manville and its
       subsidiaries, taken as a whole.

     - The absence of a material disruption of or material adverse change in
       financial, banking or capital market conditions that could materially
       impair the syndication of the senior credit facilities.

     - The occurrence of the following transactions prior to, or concurrently
       with, the initial funding of the senior secured credit facilities:

      -- Johns Manville shall have received at least $500,000,000 in cash from
         the issuance of its equity to affiliates of HB Merger LLC and HB
         Finance LLC;

      -- approximately $353,100,000 in common stock or options of Johns Manville
         held by some existing stockholders shall have been rolled over into
         pay-in-kind preferred stock, junior preferred stock and common stock of
         Johns Manville;

      -- the borrower is in receipt of net cash proceeds of at least
         $600,000,000 from the issuance of senior subordinated notes or
         borrowings under the senior subordinated bridge facility;

      -- the merger and the recapitalization shall have been approved by the
         holders of at least a majority of the outstanding common stock of Johns
         Manville and shall have been completed; and

      -- the repayment of amounts outstanding under Johns Manville's existing
         revolving credit facility and other indebtedness for borrowed money
         (other than certain debt to be agreed) and termination of related
         commitments and loans.

     - The pro forma ratio of consolidated total funded debt to consolidated
       EBITDA of Johns Manville for the twelve month period ending on the date
       of the most recently ended fiscal quarter for which internal financial
       statements are available is no greater than 4.65 to 1.0.

     - The absence of any action, suit, investigation, litigation or proceeding
       pending or known to be threatened in any court or before any arbitrator
       or governmental instrumentality relating to certain matters.

     - All representations and warranties in the senior secured credit
       documentation shall be true and correct in all material respects.

     - No default or event of default under the senior secured credit
       documentation shall exist at the time of, or after giving effect to the
       making of, the loans to be made on the closing date of the merger.

  Bridge Facility

     If the placement of senior subordinated notes cannot be consummated by the
date on which the merger is to occur, it is contemplated that a subsidiary of
Johns Manville will borrow $600,000,000 in aggregate principal amount of
unsecured exchangeable senior subordinated bridge loans from Bear Stearns
Corporate Lending Inc.

     The bridge loans will be made in a single drawing on the closing date and
are due one year following the closing date. If the bridge loans have not been
previously paid in full on the one year anniversary of

                                       55
<PAGE>   65

the closing date, the bridge loans will be automatically converted into term
loans with a final maturity date on the ten year anniversary of the closing
date. Additionally, the lenders in respect of the term loans will have the
option to request exchange notes in exchange for the term loans having the terms
described below.

     The borrower may optionally prepay the bridge loans at any time in whole or
in part, without the payment of any premium or penalty. Subject to prior
mandatory prepayments on the senior secured credit facility and exceptions to be
agreed, the borrower is required to make mandatory prepayments of the bridge
loans in respect of 100% of the net cash proceeds of any public or private
placement of any senior or subordinated debt securities, including the issuance
of any senior subordinated notes, future bank borrowings, other than under the
senior secured credit facilities, and any asset sales. Additionally, the
borrower must prepay the bridge loans upon the occurrence of a change of
control.

     The bridge loans will bear interest for each interest period at a rate
equal to the greatest of, determined at the beginning of each interest period,
the following rates, plus the applicable spread:

     - the three-month London interbank offered rate, adjusted for statutory
       reserve requirements;

     - the Bear Stearns Single B High Yield Index ; or

     - the treasury rate (the rate borne by direct obligations of the United
       States maturing on the date which is ten years after the closing date and
       if there are not such obligations, the rate determined by linear
       interpolation between the rates borne by the two obligations maturing
       closest to, but straddling, the date which is ten years after the closing
       date, as published by the Board of Governors of the Federal Reserve
       System).

     The applicable spread will initially be as follows:

     - loans based on the London interbank offered rate -- 6.75%

     - loans based on the Bear Stearns Single B High Yield Index -- 1.00%

     - loans based on the treasury rate -- 6.75%

The applicable spread will increase by 1.00% 180 days after the closing date and
by an additional 0.50% at the end of each 90 day period thereafter; provided
that the interest rate applicable to the bridge loans will not exceed 17% or the
highest rate permitted by law or be less than 13.25% per annum. The borrower has
the option to pay any interest on the bridge loans in excess of 15% per annum by
capitalizing the interest on the payment date. Additionally, at any time when
the borrower is in default of the bridge loans, the bridge loans will bear
interest at 2.0% per annum above the rate then applicable to bridge loans.

     The bridge facilities will contain a number of covenants that restrict that
ability of the borrower and its subsidiaries to incur indebtedness, grant liens,
enter into mergers, consolidations, and acquisitions, sell or transfer assets
and make dividends, distributions, redemptions and other restricted payments,
make investments, enter into transactions with affiliates, engage in certain
business activities and make material adverse amendments to their charter
documents.

     The bridge facilities will also contain events of default including the
failure to pay principal when due, nonpayment of interest, fees or other amounts
after a grace period of 5 business days, material inaccuracy of representations
or warranties, violations of covenants (subject, in certain cases to a 30 day
grace period), cross-default to other indebtedness, uninsured judgments in a
minimum amount to be agreed, bankruptcy events, certain ERISA events, material
judgments, actual or asserted invalidity of any guarantee of the bridge
facility, and the exercise of a change of control put right by any lender under
debt instruments in a minimum amount to be agreed.

     The bridge loans will be guaranteed by all of the guarantors of the senior
secured credit facilities. The guarantees of the bridge loans will be
subordinated to the guarantors' guarantee of the senior secured

                                       56
<PAGE>   66

credit facility to the same extent as the bridge loans are subordinated to the
indebtedness under the senior secured credit facilities. The bridge loans will
be unsecured.

     The availability of the bridge loans is conditioned on customary conditions
including the satisfaction of the following conditions precedent on or before
the closing date of the merger:

     - The absence of any event, development, condition or circumstance that has
       had or could reasonably be expected to have a material adverse effect on
       the merger or on the business, assets, property, condition (financial or
       otherwise), results of operations or prospects of Johns Manville and its
       subsidiaries, taken as a whole.

     - No event shall have occurred and be continuing that has caused or could
       be reasonably expected to cause any material disruption or material
       adverse change in the markets for bank debt, high yield debt or the
       financial or capital markets generally that could materially impair the
       syndication or funding of the bridge loans.

     - The following transactions shall have occurred prior to, or shall occur
       concurrently with, the funding of the bridge loans:

      -- Johns Manville shall have received at least $500,000,000 in cash from
         the issuance of equity to affiliates of HB Merger LLC and HB Finance
         LLC;

      -- approximately $353,100,000 in common stock or options of Johns Manville
         held by certain shareholders shall have been rolled over into
         pay-in-kind preferred stock, junior preferred stock and common stock of
         Johns Manville;

      -- the borrower shall have entered into the $1,750,000,000 senior credit
         facilities and all conditions precedent to borrowings under the senior
         credit facilities shall have been satisfied or waived;

      -- the merger and the recapitalization shall have been approved by the
         holders of at least a majority of the outstanding common stock of Johns
         Manville and shall have been completed; and

      -- the repayment of amounts outstanding under Johns Manville's existing
         revolving credit facility and other indebtedness for borrowed money
         (other than certain debt to be agreed and termination of related
         commitments and liens).

     - The pro forma ratio of consolidated total funded debt to consolidated
       EBITDA of Johns Manville for the twelve month period ending on the date
       of the most recently ended fiscal quarter for which internal financial
       statements are available is no greater than 4.65 to 1.0.

     - The absence of any action, suit, investigation, litigation or proceeding
       pending or known to be threatened in any court or before any arbitrator
       or governmental instrumentality relating to certain matters.

     - All representations and warranties in the bridge loan documentation shall
       be true and correct in all material respects.

     - No default or event of default under the bridge loan documentation or the
       senior credit facilities documentation shall exist at the time of, or
       after giving effect to the making of, the bridge loans or the loans under
       the senior credit facilities to be made on the closing date.

  Term Loans/Exchange Notes

     In the event the bridge loans are not paid in full on or prior to the one
year anniversary of the closing date and provided that certain events of default
are not then in existence, the bridge loans will be automatically converted to
term loans. The lender of any term loan will have the option to request exchange
notes in aggregate principal amount equal to the then outstanding term loan plus
capitalized interest added thereto. The terms loans will be governed by the
bridge loan documentation and will have the same material terms and conditions
as the bridge loans except as set forth in this section. The
                                       57
<PAGE>   67

exchange notes will be issued under an indenture that complies with the Trust
Indenture Act of 1939, as amended.

     The term loans and the exchange notes will mature on the tenth anniversary
of the closing date. The terms loans will bear interest at a rate per annum
equal to the rate borne by the bridge loans plus 0.50%, which rate shall
increase by 0.50% on the last day of each 90 day period after the one year
anniversary of the closing date; provided that the interest rate applicable to
the term loans and the exchange notes will not exceed 17.0% or the highest rate
permitted by law. The borrower will have the option to pay any interest on the
term loans or the exchange notes in excess of 15.0% by capitalizing the interest
on the payment date. Additionally, at any time when the borrower is in default
of the term loans and the exchange notes, the term loans or the exchange notes
will bear interest at 2.0% per annum above the rate then applicable to such term
loans or the exchange notes, as the case may be.

     The term loans may be redeemed at the option of the borrower at any time
without premium or penalty. The exchange notes may be redeemed at the option of
the borrower at any time without premium or penalty, except as set forth in the
next sentence. Prior to the transfer of any exchange notes to a person which was
not a bridge loan lender or its affiliate, the transferor shall give the
borrower notice of the transfer and the opportunity to redeem the applicable
exchange notes at par plus accrued interest. Once the exchange notes have been
transferred to a person which was not a bridge loan lender or its affiliate, the
exchange notes will be subject to customary call protection for fixed rate
high-yield debt securities for a period of 5 years from the closing date. Upon
the occurrence of a change of control, the borrower will offer to repay the term
loans or redeem the exchange notes, as the case may be, at a price of 101% of
the principal amount of those term loans or exchange notes, plus accrued
interest in each case.

     The indenture for the exchange notes will contain defeasance provisions,
covenants and events of default, in each case to be agreed.

CERTAIN PROJECTIONS AS TO FUTURE OPERATIONS

     Johns Manville does not as a matter of course publicly disclose projections
as to future results of operations or financial condition. However, in
connection with Johns Manville's discussions with the Hicks, Muse/Bear Stearns
group, the Hicks, Muse/Bear Stearns group was provided with some projected
financial information for Johns Manville that was prepared by management
members. This projected information was for the period from 2000 to 2005. Johns
Manville gave no assurance that these financial matters contained in these
projections would be realized.

     In order to produce the projected financial information provided to the
Hicks, Muse/Bear Stearns group, assumptions were made with respect to items,
including, but not limited to: (1) projected sales volumes; (2) projected
selling prices; (3) projected manufacturing costs; (4) projected operating
expenses; and (5) projected capital spending. Subject to the underlying
assumptions, the projections indicated that from 2000 to 2004, Johns Manville's
revenues would increase from approximately $2.3 billion to approximately $2.8
billion; Johns Manville's EBITDA would increase from approximately $525 million
to approximately $735 million; Johns Manville's income from operations would
increase from $410 million to $595 million; and Johns Manville's net income
would increase from $244 million to $420 million.

     These projections were not prepared with a view to public disclosure and
are included in this proxy statement/prospectus only because the information was
provided to the Hicks, Muse/Bear Stearns group. These projections were not
prepared with a view toward compliance with published guidelines of the SEC or
the guidelines established by the American Institute of Certified Public
Accountants regarding projections and forecasts, nor is the projected financial
information intended to be presented in a manner consistent with financial
statements prepared in accordance with generally accepted accounting principles.
While presented with numerical specificity, these projections are based upon a
variety of assumptions, some of which are referred to above, with respect to
industry performance, general business and economic conditions, taxes, and other
matters, most of which are beyond the control of Johns Manville. Neither Johns
Manville nor its financial advisors assumes any responsibility for the accuracy
of these projections, and the inclusion of this information should not be
regarded as a representation by Johns Manville or any
                                       58
<PAGE>   68

other person that these results will be achieved. Whether or not the merger is
completed, Johns Manville does not intend to make publicly available any update
or other revisions to any of these projections. In addition, because the
projections are based on a number of assumptions and are subject to significant
economic and competitive uncertainties, which are beyond the control of Johns
Manville, there can be no assurance that these projections will be realized, and
actual results may be higher or lower than those described, possibly by material
amounts.

     The projections should be read together with the information contained in
the consolidated financial statements of Johns Manville included elsewhere in
this proxy statement/prospectus including "Cautionary Statements Regarding
Forward-Looking Statements." The projections do not give effect to the merger
and the transactions contemplated thereby.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES

     The following discussion of the material United States federal income tax
consequences of the merger under currently applicable law is generally
applicable to Johns Manville and its stockholders (other than the Manville Trust
and certain members of senior management) who are citizens or residents of the
United States and hold Johns Manville common stock as capital assets. To the
extent that the following statements constitute matters of law or legal
conclusions, they are the opinion of Skadden, Arps, Slate, Meagher & Flom LLP.
The tax treatment described herein may vary depending upon each stockholder's
particular circumstances and tax position. There will be some stockholders
(including insurance companies, tax-exempt organizations, financial institutions
or broker-dealers, foreign corporations, persons who are not citizens or
residents of the U.S., stockholders who do not hold their shares as capital
assets and stockholders who have acquired their existing Johns Manville common
stock as compensation) who may be subject to special rules not discussed below.
No ruling from the Internal Revenue Service, referred to as the IRS, will be
applied for with respect to the federal income tax consequences discussed herein
and, accordingly, there can be no assurance that the IRS will agree with the
positions described herein. In addition, this discussion does not consider the
effect of any applicable foreign, state, local or other tax laws. Each
stockholder should consult his or her own tax advisor as to the particular tax
consequences to him or her of the merger, including the applicability and effect
of any foreign, state, local or other tax laws, any recent changes in applicable
tax laws and any proposed legislation.

     Characterization of the Merger

     For U.S. federal income tax purposes HB Merger LLC should be disregarded as
a transitory entity, and the merger of HB Merger LLC with and into Johns
Manville should be treated as a taxable transaction to Johns Manville
stockholders. The pay-in-kind preferred stock that Johns Manville stockholders
will receive in the merger as part of the merger consideration will be treated
for federal income tax purposes as "nonqualified preferred stock" which is not
treated as "stock" for purposes of the tax free reorganization provisions of the
Internal Revenue Code of 1986, as amended, referred to as the Code. Accordingly,
the merger should be a fully taxable transaction to Johns Manville stockholders.

     As a result of the merger, holders of Johns Manville common stock should be
treated for U.S. federal income tax purposes as if they:

     - sold a portion of their common stock of Johns Manville to affiliates of
       Hicks, Muse and Bear Stearns for cash; and

     - had a portion of their common stock of Johns Manville redeemed by Johns
       Manville for cash and the pay-in-kind preferred stock of the surviving
       corporation.

     Due to the lack of legislative, judicial or other interpretive authority on
this matter, it is unclear how the allocation of proceeds between the deemed
sale and redemption portions of the transaction should be determined. Johns
Manville intends to take the position that the percentage of a stockholder's
Johns

                                       59
<PAGE>   69

Manville common stock considered sold to the affiliates of Hicks, Muse and Bear
Stearns for cash should be equal to:

     - the amount of cash contributed to Johns Manville by the affiliates of
       Hicks, Muse and Bear Stearns; divided by

     - the aggregate amount of cash paid to all Johns Manville stockholders in
       the merger.

The remainder of a stockholder's Johns Manville common stock disposed of in the
merger should be treated as having been redeemed by Johns Manville for the
remaining cash and pay-in-kind preferred stock received in the merger.
Accordingly, the percentage of a stockholder's Johns Manville common stock that
should be treated as having been sold to the affiliates of the Hicks, Muse/Bear
Stearns group for cash should be approximately 26%, while the percentage of your
Johns Manville common stock that should be treated as having been redeemed by
Johns Manville should be approximately 74%. Your tax basis in your Johns
Manville common stock surrendered in the merger should be allocated between the
"sale" and "redemption" portions of the transaction based on these same
percentages.

     Sale of Johns Manville Common Stock to Hicks, Muse and Bear Stearns

     To the extent that a stockholder is considered to have sold Johns Manville
common stock to affiliates of Hicks, Muse and Bear Stearns, a stockholder will
recognize either capital gain or loss (assuming the common stock is held by the
stockholder as a capital asset) equal to the difference between the amount
realized on the deemed sale of common stock to affiliates of Hicks, Muse and
Bear Stearns (i.e., the cash proceeds properly allocated to such sale) and the
stockholder's adjusted tax basis allocated to such common stock. The gain or
loss will be long-term capital gain or loss if at the time of the deemed sale
the stockholder had held its Johns Manville common stock for more than one year.

     Redemption of Johns Manville Common Stock for Cash and Pay-In-Kind
     Preferred Stock

     In general, to the extent that the "redemption" portion of the transaction
is treated as a "sale or exchange" under Section 302 of the Code with respect to
a Johns Manville stockholder, such stockholder also should recognize capital
gain or loss equal to the difference between:

     - the sum of (1) the cash proceeds allocable to the redemption of such
       stockholder's common stock by Johns Manville and (2) the fair market
       value of all of the pay-in-kind preferred stock received by such
       stockholder on the effective date of the merger; and

     - the stockholder's adjusted tax basis allocated to the Johns Manville
       common stock being redeemed.

Under Section 302 of the Code, a redemption of common stock will, as a general
rule, be treated as a sale or exchange if such redemption:

     - is "substantially disproportionate" with respect to the stockholder; or

     - is "not essentially equivalent to a dividend" with respect to the
       stockholder.

In determining whether either of these two tests is met, the stockholder must
take into account the shares of stock actually owned as well as the shares of
stock constructively owned by reason of the constructive ownership rules set
forth in Section 318 of the Code. Under these constructive ownership rules, the
stockholder will be deemed to own any shares of Johns Manville common stock that
are owned, actually and in some cases constructively, by certain related
individuals or entities and any shares of Johns Manville common stock that a
stockholder has a right to acquire by exercise of an option or by conversion or
exchange of a security.

     The redemption of a stockholder's common stock will be "substantially
disproportionate" if, among other things, the percentage of shares of Johns
Manville voting stock actually and constructively owned

                                       60
<PAGE>   70

immediately following the merger is less than 80% of the percentage of shares of
voting stock actually and constructively owned immediately prior to the merger.

     The redemption of a stockholder's Johns Manville common stock will be
treated as "not essentially equivalent to a dividend" if the reduction in the
stockholder's proportionate interest in Johns Manville by reason of the merger
constitutes a "meaningful reduction" given the stockholder's particular facts
and circumstances. Depending on an individual stockholder's facts and
circumstances, even a small reduction in the stockholder's proportionate equity
interest may satisfy this test. For example, the IRS has indicated in a
published ruling that any reduction in the percentage interest of a stockholder
whose relative stock interest in a publicly held corporation is minimal (e.g.,
an interest of less than 1%) and who exercises no control over corporate affairs
should constitute a "meaningful reduction."

     Johns Manville stockholders who surrender all of their common stock for
cash and pay-in-kind preferred stock in the merger and who do not own or
constructively own any other interest in the surviving corporation following the
merger should have their redemption of common stock treated as a sale or
exchange resulting in capital gain or loss under Section 302 of the Code. The
gain or loss will be long-term capital gain or loss if at the time of the deemed
exchange the stockholder had held its common stock for more than one year. Due
to the fact-intensive nature of this determination, however, holders of Johns
Manville common stock are advised to consult with their own tax advisers
concerning the tax consequences of their particular circumstances.

     A stockholder's initial tax basis in the pay-in-kind preferred stock
received pursuant to the merger will be equal to the fair market value of such
shares at the time the merger becomes effective. A stockholder's holding period
for the pay-in-kind preferred stock will commence as of the day following the
effective date of the merger and will not include the holding period of the
Johns Manville common stock surrendered therefor.

     Distributions on Pay-In-Kind Preferred Stock

     Distributions on the pay-in-kind preferred stock whether paid in cash, in
additional shares of pay-in-kind preferred stock or as constructive
distributions (as discussed below under "Constructive Distributions on the
Pay-In-Kind Preferred Stock") will be taxable as ordinary income to the extent
that the amount of cash or the fair market value of any pay-in-kind preferred
stock distributed or constructively distributed does not exceed Johns Manville's
current and accumulated earnings and profits as determined for federal income
tax purposes. To the extent that the amount of distributions paid or
constructively paid on the pay-in-kind preferred stock exceeds such earnings and
profits, such distribution will be treated as a return of capital, reducing the
stockholder's adjusted tax basis in his or her pay-in-kind preferred stock to
the extent of such basis, with any excess taxable as capital gain. In addition,
because of the cumulative dividend feature of the pay-in-kind preferred stock,
holders of the pay-in-kind preferred stock may also have to include in income,
each year, accumulated dividends even if no actual distributions are made either
in cash or in additional shares of pay-in-kind preferred stock.

     Constructive Distributions on the Pay-In-Kind Preferred Stock

     The terms of the pay-in-kind preferred stock provide for a mandatory
redemption on the twelfth anniversary of issuance at a redemption price of 100%
of the liquidation preference plus accrued and unpaid dividends. If the
mandatory redemption price of the pay-in-kind preferred stock, including pay-in-
kind preferred stock received in lieu of a cash dividend, exceeds its issue
price by more than a de minimis amount, such excess may be treated as a
constructive distribution of additional stock on such pay-in-kind preferred
stock over the term of the pay-in-kind preferred stock, using a constant yield
method. The issue price of the pay-in-kind preferred stock should equal its fair
market value at the effective time of the merger, or its fair market value as of
the dividend payment date, if the pay-in-kind preferred stock was received in
lieu of a cash dividend. Stockholders generally will increase their basis in
their pay-in-kind preferred stock by the amount of the constructive distribution
taxable each year as ordinary income. A

                                       61
<PAGE>   71

constructive distribution of additional pay-in-kind preferred stock will
otherwise generally be subject to the same rules as described in "Distributions
on Pay-In-Kind Preferred Stock," above.

     Johns Manville's determination as to whether there is a constructive
distribution is binding on all holders of pay-in-kind preferred stock, other
than a holder that explicitly discloses that its determination as to whether
there is a constructive distribution differs from that of Johns Manville. Such
disclosure must be made on a statement attached to the holder's timely filed
federal income tax return for the taxable year that includes the date the holder
acquired the pay-in-kind preferred stock.

     Basis and Holding Period of Distributed Pay-In-Kind Preferred Shares

     A stockholder's initial tax basis in any additional shares of pay-in-kind
preferred stock actually distributed by Johns Manville will be equal to the fair
market value of the pay-in-kind preferred stock on the date of distribution. A
stockholder's holding period for such additional shares will commence on the day
following the distribution of such additional shares and will not include the
holding period for the pay-in-kind preferred stock with respect to which the
additional shares were distributed. A stockholder's tax basis in his or her
pay-in-kind preferred stock generally will increase by the amount of the
constructive distribution taxable each year as ordinary income. A stockholder's
holding period in his or her shares of pay-in-kind preferred stock should be
unaffected by constructive distributions.

     Dividends Received Deduction

     A corporate stockholder owning less than 20% of Johns Manville's stock
(calculated by vote or value) may be eligible for a 70% dividends-received
deduction with respect to dividends paid on the pay-in-kind preferred stock. The
dividends-received deduction is, however, subject to various limitations which
depend on the holder's particular circumstances, including Section 1059 of the
Code. Section 1059 of the Code would require a corporate stockholder to reduce
its tax basis in the pay-in-kind preferred stock by the amount of the
dividends-received deduction resulting from any "extraordinary dividend" paid on
the pay-in-kind preferred stock. An extraordinary dividend for purposes of
Section 1059 includes, among other items, a dividend that exceeds 5% of the
stockholder's adjusted basis in the pay-in-kind preferred stock. Corporate
stockholders should consult their tax advisors regarding the availability of the
dividends-received deduction and the possible application of Section 1059 of the
Code or other limitations with respect to their particular circumstances.

     Disposition of Pay-In-Kind Preferred Stock

     Upon the sale, exchange or other disposition of pay-in-kind preferred
stock, other than by redemption, the Johns Manville stockholders generally will
recognize capital gain or loss equal to the difference between the amount
realized upon the disposition and the adjusted tax basis in the pay-in-kind
preferred stock. This gain or loss will be long-term capital gain or loss if at
the time of the disposition the stockholder has held the pay-in-kind preferred
stock for more than one year.

     Information Reporting and Backup Withholding

     Backup withholding at a rate of 31% may apply with respect to cash payments
received by Johns Manville stockholders unless the recipient:

     - is a corporation or other exempt recipient and when required demonstrates
       this fact; or

     - provides a correct taxpayer identification number, certifies as to no
       loss of exemption from backup withholding and otherwise complies with
       applicable requirements of the backup withholding rules.

A Johns Manville stockholder who does not provide Johns Manville with his or her
correct taxpayer identification number may be subject to penalties imposed by
the IRS. Any amounts withheld under the backup withholding rules may be allowed
as a refund or credit against the stockholder's federal income tax liability
provided that certain required information is furnished to the IRS.

     ALTHOUGH THE FOREGOING ARE THE MATERIAL U.S. FEDERAL INCOME TAX
CONSIDERATIONS GENERALLY APPLICABLE TO THE MERGER, THE DISCUSSION DOES NOT
ADDRESS EVERY U.S. FEDERAL INCOME TAX CONCERN WHICH MAY BE APPLICABLE TO A
PARTICULAR STOCKHOLDER. EACH STOCKHOLDER IS URGED TO CONSULT SUCH STOCKHOLDER'S
OWN TAX ADVISOR TO DETERMINE THE TAX CONSEQUENCES TO SUCH STOCKHOLDER, IN THE
LIGHT OF HIS OR HER PARTICULAR CIRCUMSTANCES, OF THE DISPOSITION OF JOHNS
MANVILLE COMMON STOCK PURSUANT TO THE MERGER.

ACCOUNTING TREATMENT

     For financial reporting purposes, the merger and all transactions
contemplated by the merger agreement are intended by the Hicks, Muse/Bear
Stearns group to be accounted for as a leveraged recapitalization, which means a
transaction structured to transfer the controlling interest of an operating
entity to a new investor without a change in accounting basis of the assets and
liabilities presented in the separate stand-alone financial statements of the
operating entity.

FEDERAL SECURITIES LAWS CONSEQUENCES

     The prospectus, which constitutes a part of this proxy statement/prospectus
related to the issuance of the pay-in-kind preferred stock in the merger, does
not cover any resales of the common stock or preferred stock of the surviving
corporation to be received by some of the shareholders of Johns Manville in the
merger, and no person is authorized to make any use of this proxy
statement/prospectus in connection with any such resale.

     All shares of pay-in-kind preferred stock received by Johns Manville
stockholders in the merger will be freely transferable, except that shares of
pay-in-kind preferred stock received by persons who are deemed to be
"affiliates" of Johns Manville under the Securities Act of 1933, as amended, at
the time of the stockholders meeting may be resold by them only in transactions
permitted by Rule 144 under the 1933 Act or as otherwise permitted under the
1933 Act. Persons who may be deemed to be affiliates of Johns Manville for such
purposes generally include individuals or entities that control, are controlled
by or are under common control with Johns Manville, and include directors and
executive officers of Johns Manville and include the Manville Trust.

     The holdback agreement between the Manville Trust and Bear Stearns
Corporate Lending provides restrictions on the transfer of pay-in-kind preferred
stock and the stockholders agreement provides restrictions on the transfer of
shares of the surviving corporation common stock. For more information regarding
these restrictions, please see "Other Relevant Agreements -- The Stockholders
Agreement" and "-- The Holdback Agreement."

APPRAISAL RIGHTS OF STOCKHOLDERS

     Delaware law entitles the holders of record of shares of Johns Manville
common stock who follow the procedures specified in Section 262 of the Delaware
law to have their shares appraised by the Delaware Court of Chancery and to
receive the "fair value" of such shares as of the effective time of the merger
as determined by the court in place of the merger consideration. In order to
exercise these rights, a stockholder must demand and perfect the rights in
accordance with Section 262. The following is a summary of Section 262 and is
qualified in its entirety by reference to Section 262, a copy of which is
attached as Appendix F to this proxy statement/prospectus. Stockholders should
carefully review Section 262 as well as information discussed below to determine
their rights to appraisal.

     If a stockholder of Johns Manville elects to exercise the right to an
appraisal under Section 262, that stockholder must do all of the following:

          (1) deliver to Johns Manville, a written demand for appraisal of
     shares of Johns Manville common stock held, which demand must identify the
     stockholder and expressly request an appraisal, before the vote is taken on
     the merger agreement at the annual meeting (this written demand for
     appraisal must be in addition to and separate from any proxy or vote
     against the merger agreement;

                                       63
<PAGE>   73

     neither voting against, abstaining from voting nor failing to vote on the
     merger agreement will constitute a demand for appraisal within the meaning
     of Section 262);

          (2) not vote in favor of adoption of the merger agreement (a failure
     to vote or abstaining from voting will satisfy this requirement, but a vote
     in favor of adoption of the merger agreement, by proxy or in person, or the
     return of a signed proxy that does not specify a vote against adoption of
     the merger agreement, will constitute a waiver of such stockholder's right
     of appraisal and will nullify any previously filed written demand for
     appraisal); and

          (3) continuously hold such shares through the time the merger becomes
     effective.

     All written demands for appraisal should be addressed to: Johns Manville
Corporation, 717 17th Street, Denver, Colorado 80217-5108, Attention: Corporate
Secretary, before the vote is taken on the merger agreement at the special
meeting, and should be executed by, or on behalf of, the holder of record. Such
demand must reasonably inform Johns Manville of the identity of the stockholder
and that the stockholder is thereby demanding appraisal of his or her shares of
Johns Manville common stock.

     Within 10 days after the effective time of the merger, the surviving
corporation of the merger will give written notice of the effective time of the
merger to each stockholder of Johns Manville who has satisfied the requirements
of Section 262 and has not voted for the proposal to adopt the merger agreement,
referred to as a dissenting stockholder. Within 120 days after the effective
time of the merger, the surviving corporation or any dissenting stockholder may
file a petition in the court demanding a determination of the fair value of the
shares of Johns Manville common stock that are held by all dissenting
stockholders. Any dissenting stockholder desiring to file this petition is
advised to file the petition on a timely basis unless the dissenting stockholder
receives notice that a petition has already been filed by the surviving
corporation or another dissenting stockholder.

     If a petition for appraisal is timely filed, the court will determine which
stockholders are entitled to appraisal rights and thereafter will determine the
fair value of the shares of Johns Manville common stock held by dissenting
stockholders, exclusive of any element of value arising from the accomplishment
or expectation of the merger, but together with a fair rate of interest, if any,
to be paid on the amount determined to be fair value. In determining the fair
value, the court is to take into account all relevant factors. The court may
determine such fair value to be more than, less than or equal to the
consideration that the dissenting stockholder would otherwise be entitled to
receive pursuant to the merger agreement. If a petition for appraisal is not
timely filed, then the right to an appraisal shall cease. The costs of the
appraisal proceeding are to be determined by the court and taxed against the
parties as the court determines to be equitable under the circumstances. Upon
the application of any stockholder, the court may determine the amount of
interest, if any, to be paid upon the value of the shares of Johns Manville
common stock of stockholders entitled to such interest. Upon application of a
stockholder, the court may order all or a portion of the expenses incurred by
any stockholder in connection with the appraisal proceeding, including, without
limitation, reasonable attorneys' fees and the fees and expenses of experts, to
be charged pro rata against the value of all shares of Johns Manville common
stock entitled to appraisal.

     From and after the effective time, no dissenting stockholder shall have any
rights of a Johns Manville stockholder with respect to such holder's shares for
any purpose, except to receive payment of its fair value and to receive payment
of dividends or other distributions on such holder's shares of Johns Manville
common stock, if any, payable to Johns Manville stockholders of record as of a
date prior to the effective time. If a dissenting stockholder delivers to the
surviving corporation a written withdrawal of the demand for an appraisal within
60 days after the effective time of the merger or thereafter with the written
approval of the surviving corporation, or, if no petition for appraisal is filed
within 120 days after the effective time, then the right of that dissenting
stockholder to an appraisal will cease and the dissenting stockholder will be
entitled to receive only the merger consideration.

LITIGATION CHALLENGING THE MERGER

     On or about June 2000, four complaints were filed in Delaware Chancery
Court entitled: Phillip Rothe v. Johns Manville Corp. et al., Civil Action No.
18121-NC; Ernest Mack v. Johns Manville Corp., et al., Civil Action No.
18122-NC; Jerry Krim v. Johns Manville et al., Civil Action No. 18130-NC; and
Crandon Capital Partners v. Johns Manville et al., Civil Action No. 18125-NC.
These complaints assert claims against Johns Manville and some of its officers
and directors. The Mack and Rothe complaints also assert claims against the
Manville Trust. All four complaints purport to assert claims on behalf of a
purported class of Johns Manville's stockholders and challenge the proposed
acquisition pursuant to a merger of Johns Manville's common stock by the Hicks,
Muse/Bear Stearns group by alleging, among other things, that the merger and the
transactions contemplated in connection with the merger are unfair, inadequate,
below the fair value of Johns Manville and that the actions of the defendants
constitute a breach of their fiduciary duties. The complaints seek, among other
things, to enjoin the merger, to rescind the merger if it is consummated and
also seek damages, fees, expenses and interest. Johns Manville intends to defend
against the lawsuits vigorously.

                              THE MERGER AGREEMENT

     The following is a brief summary of the material provisions of the merger
agreement. The following summary is qualified in its entirety by reference to
the merger agreement, which we have attached as Appendix A to this proxy
statement/prospectus and which we incorporate by reference into this document.
We encourage you to read the merger agreement carefully and in its entirety.

THE MERGER

     The parties to the merger agreement are Johns Manville, HB Merger LLC and
HB Finance LLC.

     The merger agreement provides that, following the adoption of the merger
agreement by stockholders and the satisfaction or waiver of the other conditions
to the merger, HB Merger LLC will be merged with and into Johns Manville, and
Johns Manville will be the surviving corporation. The merger will become
effective upon the filing of a certificate of merger with the Secretary of State
of the State of Delaware or at such later time agreed to by the parties and
specified in the certificate of merger.

     When the merger becomes effective and HB Merger LLC has been merged with
and into Johns Manville, a new amended and restated certificate of
incorporation, referred to as the surviving corporation amended and restated
certificate of incorporation, will become the certificate of incorporation of
Johns Manville. We have attached a copy of the surviving corporation amended and
restated certificate of incorporation as Appendix H to this proxy
statement/prospectus.

CONSIDERATION

     In the merger, each outstanding share of Johns Manville common stock; other
than any shares owned by shareholders who perfect appraisal rights, and shares
that are held by Johns Manville as treasury stock or held by HB Merger LLC or
its subsidiaries will be converted into the right to receive $13.625 in cash and
0.02 of a share of pay-in-kind preferred stock of the surviving corporation.

     In the merger, each outstanding share of class TM preferred stock will be
converted into the right to receive 0.6 of a share of surviving corporation
common stock and 0.4 of a share of surviving corporation junior preferred stock.
Upon conversion of the Johns Manville common stock into the merger consideration
described above, the Johns Manville common stock will be cancelled and retired.
No fractional shares of surviving corporation pay-in-kind preferred stock,
surviving corporation junior preferred stock or surviving corporation common
stock will be issued in the merger. Instead, stockholders who are entitled to
fractions of shares will receive the cash value of these fractions of shares.

     Each issued and outstanding membership interest in HB Merger LLC will be
converted into 0.6 of a share of surviving corporation common stock and 0.4 of a
share of surviving corporation junior preferred stock.

     Each outstanding employee option will be cancelled and each holder will be
entitled to receive an amount of cash computed by multiplying

     - the excess, if any, of (A) the greater of (x) $15.625 and (y) the highest
       fair market value per share at any time during the 60-day period
       preceding the merger, over (B) the exercise price per share subject to
       such option by

     - the number of shares subject to such option. Each share of deferred stock
       will be cancelled and the holder will be entitled to receive an amount in
       cash equal to the greater of (x) $15.625 and (y) the highest fair market
       value per share at any time during the 60-day period preceding the
       merger.

     Except as provided in the next paragraph, cash payments will be made in
settlement of each deferral account under Johns Manville's Deferred Compensation
Plan and Non-Employee Directors' Deferred Compensation Plan. See "Interest in
the Merger That Differ From Your Interests".

                                       66
<PAGE>   76

     Mr. Henry's employment agreement provides that his deferral account deemed
to be invested in Johns Manville common stock will be rolled over into shares of
surviving corporation common stock and surviving corporation junior preferred
stock. Other members of management whose deferral accounts are deemed to be
invested in Johns Manville common stock will have the right to elect to roll
over a portion of their deemed Johns Manville shares into shares of surviving
corporation common stock and surviving corporation junior preferred stock or
other equity rights in the surviving corporation.

EXCHANGE OF SHARES

     HB Merger LLC will appoint an exchange agent to handle the surrender of
certificates and payment of the merger consideration. Immediately before the
closing of the merger, HB Finance LLC and Johns Manville will deposit an amount
of cash and a number of certificates of surviving corporation common stock,
pay-in-kind preferred stock and junior preferred stock required to pay the
holders of Johns Manville common stock and class TM common stock, the cash and
stock merger consideration, as well as cash in lieu of fractional shares, to
which each is entitled. Soon after the closing, the exchange agent will send to
each former holder of Johns Manville common stock a letter of transmittal for
use in the surrender and instructions explaining how to surrender stock
certificates to the exchange agent. Holders of Johns Manville common stock that
surrender their certificates and provide to the exchange agent a properly
completed letter of transmittal will receive the appropriate merger
consideration. Holders of unexchanged shares of Johns Manville common stock will
not be entitled to receive any dividends or other distributions payable after
the closing except that when they surrender their certificates they will be
entitled to dividends and distributions on the pay-in-kind preferred stock.

     You should not send in your Johns Manville common stock certificates until
you receive a transmittal form. You should send them only pursuant to
instructions set forth in the letter of transmittal. In all cases, the merger
consideration will be provided only in accordance with the procedures set forth
in the merger agreement and those letters of transmittal.

     Any merger consideration not validly claimed by Johns Manville stockholders
within one year after the effective time and any interest and other income
received by the exchange agent relating to that merger consideration will be
delivered to Johns Manville upon demand. Any holders of shares of common stock
who have not complied with the terms and conditions for the exchange of
certificates set forth in the merger agreement will thereafter look only to
Johns Manville, and only as general creditors, for the payment of their claim to
the merger consideration.

NON-SOLICITATION; ACQUISITION PROPOSALS

     The merger agreement provides that Johns Manville and its subsidiaries will
not, and will instruct their respective officers, directors, advisors and other
representatives not to:

     - initiate, solicit, encourage or facilitate the making of any acquisition
       proposal, as defined below, or

     - engage in negotiations or discussions with, or furnish any non-public
       information or data to, any third party relating to an acquisition
       proposal.

     However, until adoption of the merger agreement, Johns Manville and its
board may:

     - participate in negotiations or provide information to a third party if
       either (1) the Johns Manville board determines in good faith, that a
       third party has made a superior proposal, or an acquisition proposal
       (both as defined below) that the board concludes would likely constitute
       a superior proposal, and that superior proposal was not solicited by
       Johns Manville or its affiliates or agents, or (2) the board determines
       in good faith, after consultation with independent counsel, that failure
       to participate in negotiations would be reasonably likely to constitute a
       breach of the board's fiduciary duties;

     - disclose to stockholders a position with respect to the merger or another
       acquisition proposal if required by applicable law or such other
       disclosure as the board determines after consultation with independent
       counsel, is required under applicable law; and

     - request from a person making an acquisition proposal such information as
       reasonably necessary to permit the board to inform itself of the material
       terms thereof.

An acquisition proposal under the merger agreement means any bona fide proposal
for the:

     - direct or indirect acquisition or purchase of a business or assets that
       constitutes 15% or more of the net revenues, net income or assets of
       Johns Manville and its subsidiaries, taken as a whole;

                                       69
<PAGE>   79

     - direct or indirect acquisition or purchase of 15% or more of any class of
       equity securities or capital stock of Johns Manville or any of its
       subsidiaries whose business constitutes 15% or more of the net revenues,
       net income or assets of Johns Manville and its subsidiaries, taken as a
       whole; or

     - merger, consolidation, restructuring, transfer of assets or other
       business combination, sale of shares of capital stock, tender offer,
       exchange offer, recapitalization, stock repurchase program or other
       similar transaction that if consummated would result in any person or
       persons beneficially owning 15% or more of any class of equity securities
       of Johns Manville or any of its subsidiaries whose business constitutes
       15% or more of the net revenues, net income or assets of Johns Manville
       and its subsidiaries, taken as a whole.

     A superior proposal under the merger agreement means any bona fide proposal
to enter into an acquisition proposal which was not solicited by Johns Manville
and is made by a third party on terms and conditions which the board of
directors determines in its good faith judgment, after receiving the advice of
its financial advisors, to be more favorable to the holders of Johns Manville
common stock from a financial point of view than the transactions contemplated
by the merger agreement, taking account of all of the terms thereof, including
price, likelihood of financing being available and expected timing of
consummation.

     Johns Manville will promptly advise HB Merger LLC, both orally and in
writing of the terms of any acquisition proposal by the end of the next business
day, but in no event more than 36 hours after receipt, and the identity of the
party making the proposal, and will keep HB Merger LLC reasonably informed as to
the status and material terms.

ACCESS TO INFORMATION

     Johns Manville has agreed to provide HB Merger LLC with reasonable access
to its books and records until the effective time of the merger.

COMMERCIALLY REASONABLE EFFORTS

     Each of the parties will use its commercially reasonable efforts to
consummate the transaction, including to obtain necessary consents and
approvals. HB Merger LLC and HB Finance LLC will use their commercially
reasonable efforts to obtain the contemplated financing, and Johns Manville will
cooperate with HB Merger LLC in obtaining its financing. Johns Manville will use
its commercially reasonable efforts to take all action necessary, including
amending the merger agreement, to permit the surviving corporation to be
entitled to recapitalization accounting treatment, provided that the Johns
Manville board determines that an action of this kind would not reasonably be
expected to adversely affect Johns Manville or any of its stockholders.

EMPLOYEE BENEFITS

     The surviving corporation will assume all of Johns Manville's employment,
retention, consulting and severance agreements. Core benefits that are no less
favorable than those currently provided are to be provided to employees until
the end of 2001. The surviving corporation will also maintain Johns Manville's
separation policy for eighteen months.

     The surviving corporation will pay on or before February 15, 2001, bonuses
under Johns Manville's annual incentive compensation plans pro rated through the
date of the closing, and the surviving corporation will implement a similar plan
for the remainder of the year following the closing.

STOCKHOLDERS MEETING

     Johns Manville will call and hold as promptly as reasonably practicable the
stockholders meeting to approve the amendment to the restated certificate of
incorporation and adopt the merger agreement. Johns Manville agreed to prepare
and file this proxy statement/prospectus in connection with the stockholders

                                       70
<PAGE>   80

meeting and the registration of the pay-in-kind preferred stock. Johns Manville
also agreed, subject to the fiduciary duties of the Johns Manville board and
applicable law, to include in this proxy statement/ prospectus the board's
recommendation of the merger and the amendment to the restated certificate of
incorporation.

INDEMNIFICATION

     The surviving corporation will indemnify directors, officers, employees and
agents of Johns Manville to the fullest extent permitted by law at all times
after the merger for any claim based on actions taken prior to the effective
time of the merger and shall maintain directors' and officers' liability
insurance for a period of six years for such actions, limited by annual cost cap
of 200% of current premium; and indemnity provisions in the surviving
corporation's certificate of incorporation and bylaws will be maintained for six
years after the merger.

     Whether or not the merger occurs, the surviving corporation will indemnify
all current and prior employees, agents, directors or officers of HB Merger LLC
and HB Finance LLC for any claim that is primarily based on an allegation that
HB Merger LLC or its affiliates has induced or acted in concert with Johns
Manville or its directors to act contrary to or in violation of any contract,
duty or applicable law to which Johns Manville and the directors are subject.

ENVIRONMENTAL ASSESSMENTS AND ENVIRONMENTAL TRANSFER LAWS

     In the event that Johns Manville or HB Merger LLC receives information
which leads it to conclude in good faith that a site has associated
environmental costs and liabilities which would have a material adverse effect
on Johns Manville, then HB Merger LLC may conduct additional environmental tests
at its sole cost. Johns Manville will use its commercially reasonable efforts to
ensure compliance with all environmental property transfer laws prior to the
closing of the merger.

SOLVENCY LETTER

     HB Merger LLC has retained Corporate Valuation Advisors, Inc. to deliver at
the closing a solvency letter addressed to HB Merger LLC, Johns Manville and the
Johns Manville board stating that, immediately after the effective time of the
merger, the surviving corporation will be solvent, will not have unreasonably
small capital and will not have incurred debts beyond its ability to pay.

LISTING FOR PAY-IN-KIND PREFERRED STOCK

pay-in-kind preferred stock eligible for trading on the Nasdaq national market,

       would preclude application of recapitalization accounting to the
       transaction.

TERMINATION

     The merger agreement may be terminated by mutual written consent or by
either Johns Manville or HB Merger LLC if one of the following occurs:

     - the merger is not consummated by November 30, 2000; however, this date
       will be extended to December 28, 2000 if the stockholders meeting has not
       been held on or before November 1, 2000 and will be further extended to
       January 31, 2001 if the stockholders meeting has not been held on or
       prior to December 1, 2000;

     - stockholders fail to approve the amendment to the restated certificate of
       incorporation or adopt the merger agreement;

     - there is a permanent injunction or order prohibiting the merger;

     - the other party materially breaches its obligations after having been
       given an opportunity to cure; or

     - the voting agreement is terminated by either HB Merger LLC or the
       Manville Trust because (1) the Johns Manville board modifies or withdraws
       its recommendation, (2) the approval of the U.S. bankruptcy court is not
       obtained or (3) the Manville Trust enters into a binding agreement
       regarding a superior proposal.

     The merger agreement may also be terminated by Johns Manville if a superior
proposal is made prior to the stockholder vote adopting the merger agreement and
approving the amendment to the restated

                                       72
<PAGE>   82

charter and Johns Manville enters into a binding written agreement, in which
event, Johns Manville must notify HB Merger LLC in writing that it intends to
enter into such an agreement and for five business days after the notice, must
negotiate with HB Merger LLC. In order to terminate the agreement in these
circumstances, Johns Manville must pay the termination fee referred to below
under "Fees and Expenses."

     The merger agreement may also be terminated by HB Merger LLC if:

     - Johns Manville enters into an agreement for a superior proposal;

     - the Johns Manville board shall have withdrawn or adversely modified its
       approval or recommendation and the Manville Trust shall have terminated
       the voting agreement;

     - Johns Manville continues to engage in negotiations with, or furnish
       information to, a third party relating to an acquisition proposal for a
       period of more than 45 days; and

     - the stockholder meeting has not been held by January 15, 2001, so long as
       HB Merger LLC has not materially contributed to the failure and the
       stockholders meeting has not been enjoined.

FEES AND EXPENSES

     Each party will pay its own fees and expenses except as described below.
Johns Manville estimates that merger-related fees and expenses, consisting
primarily of SEC filing fees, fees and expenses of investment bankers, attorneys
and accountants, and financial printing and other related charges, will total
approximately $     million assuming the merger is completed.

     Johns Manville will pay to HB Merger LLC (1) a termination fee of
$53,000,000 and (2) reimbursement for out-of-pocket expenses not in excess of
$12,500,000 if one of the following occurs:

     - Johns Manville terminates the merger agreement to enter into a superior
       proposal or HB Merger LLC terminates the agreement because Johns Manville
       enters into a superior proposal; or

     - the merger agreement is terminated because the voting agreement is
       terminated by the Manville Trust due to the Johns Manville board
       withdrawing its recommendation or the Manville Trust entering into a
       superior proposal.

     Johns Manville will pay to HB Merger LLC its (1) out-of-pocket expenses not
in excess of $12,500,000 at the time of termination and (2) the $53,000,000
termination fee upon signing or closing an acquisition proposal if prior to the
first anniversary of the termination Johns Manville enters into an agreement
with respect to, or consummates, an acquisition proposal, and termination was as
follows:

     - if HB Merger LLC terminated the merger agreement because Johns Manville
       continued to engage in negotiations with, or furnish information to, a
       third party relating to an acquisition proposal for a period of more than
       45 days;

     - if HB Merger LLC terminated the merger agreement because the stockholder
       meeting has not been held by January 15, 2001, so long as HB Merger LLC
       has not materially contributed to the failure and the stockholders
       meeting has not been enjoined;

     - if Johns Manville or HB Merger LLC terminated the agreement because the
       voting agreement was terminated due to the order of the U.S. bankruptcy
       court not having been obtained; provided that Johns Manville is only
       required to pay a termination fee upon Johns Manville entering into or
       consummating an acquisition proposal prior to the first anniversary of
       termination if such acquisition proposal is with a person who made an
       acquisition proposal after the date of the confidentiality agreement that
       was entered into between Bear Stearns and Johns Manville and prior to the
       time that the court entered its decision or the consideration to be paid
       in such transaction is of equal or greater value than the consideration
       to be paid to stockholders under the merger agreement;

                                       73
<PAGE>   83

     - if HB Merger LLC terminated the merger agreement due to Johns Manville's
       willful breach of a representation or willful breach of a covenant which
       results in the relevant closing condition not being met; or

     - if the merger agreement is terminated due to Johns Manville stockholders
       failing to approve the merger agreement.

     Johns Manville will pay to HB Merger LLC its out-of-pocket expenses not in
excess of $12,500,000 if HB Merger LLC terminates the agreement as a result of a
breach of a covenant that was not willful which results in the relevant closing
condition not being met.

                           OTHER RELEVANT AGREEMENTS

THE VOTING AGREEMENT

     The following summary is qualified in its entirety by reference to the
voting agreement, which is an exhibit to the registration statement of which
this proxy statement/prospectus forms a part.

     The Manville Trust and HB Merger LLC have entered into the voting agreement
which provides that the Manville Trust agrees to vote all of its shares of Johns
Manville common stock in favor of the adoption of the merger agreement and the
amendment to the restated certificate of incorporation; against any proposal to
the stockholders of Johns Manville which would prevent the consummation of the
merger and against any acquisition proposal other than the merger. The Manville
Trust voting obligation only arises upon issuance of approval by the U.S.
bankruptcy court.

     The Manville Trust has agreed it will not, while the voting agreement is in
effect, except for the conversion of some of its shares into class TM preferred
stock in connection with the merger, offer for sale, sell, transfer, pledge,
assign or otherwise dispose of any of its shares of Johns Manville common stock.
Additionally, except in connection with the voting agreement and stockholders
meeting to be held to approve the merger, the Manville Trust will not grant any
proxies or powers of attorney, deposit any of its shares of Johns Manville
common stock into a voting trust or enter into a voting agreement with respect
to its shares of Johns Manville common stock.

     The Manville Trust has agreed it will use its commercially reasonable
efforts to take all action and to do all things reasonably necessary to obtain
the approval of the U.S. bankruptcy court, and oppose any attempt of which it
has knowledge to have the approval of the U.S. bankruptcy court vacated,
reversed or amend so as to materially limit the court approval.

     The Manville Trust has agreed it will, on or before the date of the closing
of the merger, execute and deliver the stockholders agreement, which is
described below.

     In addition, the Manville Trust has agreed it will not, and will instruct
its trustees, offices and advisors and other representatives not to, solicit,
initiate, encourage or facilitate any of its advisors to solicit any acquisition
proposal, or engage in negotiations or discussions with, or furnish any
non-public or data to, any third party relating to any superior stockholder
proposal. However, the Manville Trust may:

     - participate in negotiations or provide information to a third party prior
       to the court approval if the Johns Manville board has participated in
       such negotiations or discussions with a third party because it has
       determined that it is a superior stockholder proposal, or the trustees
       determine in good faith:

      -- that a third party has made a superior stockholder proposal and the
         trustees have received the advice of their financial advisors, or

      -- after consultation with independent counsel, that failure to
         participate in negotiations would be substantially likely to constitute
         a breach of the trustees' fiduciary duties; or

     - request from a person making an acquisition proposal the information that
       is reasonably necessary for its trustees to inform themselves of its
       material terms.
                                       74
<PAGE>   84

     Acquisition proposal is defined in the merger agreement and on page 66 of
this proxy statement/ prospectus. A superior stockholder proposal under the
voting agreement means any bona fide proposal, that was not solicited by the
Manville Trust or any of its trustees, to enter into an acquisition proposal
made by a third party on terms and conditions which the trustees of the Manville
Trust determine in their good faith, on the advice of the Manville Trust's
financial advisors, to be more favorable to the Manville Trust from a financial
point of view than the transactions contemplated by the merger agreement, taking
account of all of the terms thereof, including price, likelihood of financing
being available and expected timing of consummation.

     If the Manville Trust is entitled to engage in negotiations with a third
party because of the superior proposal, it may:

     - withhold its vote in favor of the adoption of the merger agreement and
       approval of the amendment to the restated certificate of incorporation,

     - approve any acquisition proposal, or

     - enter into an agreement with respect to the acquisition proposal.

     The voting agreement will terminate automatically if the merger agreement
is terminated or the merger is consummated.

     The voting agreement may be terminated by the Manville Trust:

     - if prior to the receipt of U.S. bankruptcy court approval, the Johns
       Manville board modifies or withdraws its recommendation of the merger
       agreement;

     - if the U.S. bankruptcy court fails to issue its approval after a hearing
       or its approval is vacated or withdrawn; or

     - if prior to the receipt of the approval of the U.S. bankruptcy court, the
       trustees authorize the Manville Trust to enter into an agreement with
       respect to a superior proposal.

     The voting agreement may be terminated by HB Merger LLC:

     - if the U.S. bankruptcy court fails to issue the approval after a hearing
       or the approval is overruled; or

     - if the Manville Trust enters into an agreement with respect to a superior
       stockholder proposal.

TAX AGREEMENT

     The following summary is qualified in its entirety by reference to the tax
agreement, which is an exhibit to the registration statement of which this proxy
statement/prospectus forms a part.

     Johns Manville is statutorily liable for all federal income taxes of the
designated settlement fund portion of the Manville Trust, and is contractually
liable, under an agreement with the Manville Trust known as the supplemental
agreement, for other income taxes of the Manville Trust. In connection with the
merger, Johns Manville and the Manville Trust entered into the tax agreement to
settle Johns Manville's liability for taxes of the Manville Trust. The tax
agreement provides that upon consummation of the merger Johns Manville will pay
$90,000,000 in cash to the Manville Trust. In return, the Manville Trust will
terminate Johns Manville's contractual liability for taxes of the Manville Trust
and indemnify Johns Manville and its successors for all income taxes of the
Manville Trust, and related costs, expenses, losses, penalties and damages
arising from the tax liabilities which Johns Manville may have owed. All or a
portion of the proceeds paid to the Manville Trust will be placed in escrow to
underlie the Manville Trust's indemnification obligations.

     In addition, Johns Manville and the Manville Trust have agreed in the tax
agreement that they will, at the closing of the transaction under the tax
agreement enter into a third amended and restated

                                       75
<PAGE>   85

supplemental agreement, an amendment to the Manville Trust amended and restated
Trust Agreement and an escrow agreement, each of which is described below.

     The parties' obligations to consummate the tax agreement are subject to
conditions including:

     - the Manville Trust having obtained the concurrence of the current legal
       representative of the future claimants against the Trust and the selected
       counsel for beneficiaries;

     - approval from the U.S. bankruptcy court;

     - receipt of all necessary government licenses, consents and approvals, and
       absence of any injunction;

     - the merger having been consummated; and

     - the Manville Trust having instructed its banking institution that all
       cash proceeds paid to the Manville Trust as a result of the merger will
       be transferred to the designated settlement fund portion of the Trust.

  Amendment to Supplemental Agreement

     The third amended and restated supplemental agreement replaces the
supplemental agreement between the Manville Trust and Johns Manville, which was
originally dated November 28, 1988, in its entirety. The amended supplemental
agreement provides that the Manville Trust will indemnify Johns Manville for all
losses incurred by Johns Manville in connection with any claim for death,
personal injury or personal damages to the extent caused by exposure to asbestos
and certain related matters. In addition, Johns Manville will continue its
obligation to indemnify the Manville Trust for all losses incurred by the
Manville Trust in connection with any obligations or liabilities of Johns
Manville and its subsidiaries not assumed by the Manville Trust under the trust
agreement. The amended supplemental agreement provides that Johns Manville will
have no further contractual obligation to pay any income tax liabilities of the
designated settlement fund portion of the Manville Trust, except as provided for
in the tax agreement.

  Amendment to Trust Agreement

     The amendment to the Manville Trust amended and restated trust agreement
will amend the trust agreement, dated April 29, 1997, under which the Manville
Trust is governed. The amendment to the trust agreement modifies some powers of
the Manville Trust, and provides that the Manville Trust will be allowed to
guarantee debts in the ordinary course of business in respect of the operating
agreement of its wholly owned subsidiary established to administer funds
designated for the resolution of claims for asbestos-related injuries. The
amendment provides that no trust claims will become liabilities of Johns
Manville upon termination of the Manville Trust. Future amendments to the trust
agreement will be permissible without the consent of Johns Manville, except for
amendments to the termination or amendment provisions of the trust agreement and
amendments that adversely affect Johns Manville.

  Escrow Agreement

     Johns Manville and the Manville Trust have agreed in the tax agreement to
enter into an escrow agreement at the time of the closing of the transactions
contemplated by the tax agreement. The escrow agreement requires that the
Manville Trust deposit $90,000,000 into an escrow account with an escrow agent
for the purposes of paying all federal, state, local or foreign income taxes
imposed on the designated settlement fund portion of the Manville Trust. The
amount of $90,000,000 may be reduced if the United States bankruptcy court
issues an order providing that, in connection the with the liquidation,
bankruptcy, reorganization or winding up of the Manville Trust:

     - the trustees of the Manville Trust, prior to paying beneficiaries,
       creditors or possible asbestos-related injury claimants of the Manville
       Trust will pay from the funds held in escrow the amount of taxes owed to
       the Internal Revenue Service and the other applicable taxing authorities;
       and/or

                                       76
<PAGE>   86

     - Johns Manville will have priority over beneficiaries, creditors or
       possible claimants of the Manville Trust with respect to its claims for
       indemnification for taxes as provided in the tax agreement.

     Subject to the terms of the escrow agreement, the amount of funds contained
in the escrow account will be adjusted from time to time.

EXCHANGE AGREEMENT

     Johns Manville, the Manville Trust and some members of the management of
Johns Manville have entered into an exchange agreement under which some of the
shares of Johns Manville common stock held by the Manville Trust and those
members of the management will be converted into class TM preferred stock
immediately prior to the closing of the merger. Although neither the Manville
Trust nor individual members of the management are parties to the merger
agreement, it is a condition to the closing of the merger agreement that these
parties have entered into the exchange agreement.

     Immediately before the closing of the merger, each stockholder who is a
party to the exchange agreement will exchange, a number of shares of its common
stock for an equal number of shares of class TM preferred stock. The merger
agreement provides that at the effective time of the merger, each share of class
TM preferred stock will be automatically converted into 0.6 of a share of
surviving corporation common stock and 0.4 of a share of surviving corporation
junior preferred stock.

     The obligations of the Manville Trust, Johns Manville and the members of
the management who are parties to the exchange agreement to complete the
exchange transaction under the exchange agreement are subject to the following
conditions:

     - the absence of any injunction prohibiting the completion of the
       transaction;

     - approval by the Johns Manville stockholders of the amendment to John
       Manville's restated certificate of incorporation;

     - receipt of the U.S. bankruptcy court approval; and

     - the representations and warranties given in the exchange agreement by
       each party being true in all material respects, and each of the parties
       having performed all of the obligations required of it under the exchange
       agreement.

     The exchange agreement will terminate automatically if the merger agreement
is terminated or upon the collective agreement of each of the parties to the
exchange agreement and HB Merger LLC. Upon termination of the exchange
agreement, all shares of class TM preferred stock that have been issued to the
Manville Trust or members of management will automatically convert into an equal
number of shares of Johns Manville common stock.

LETTER AGREEMENT WITH THE MANVILLE TRUST

     The letter agreement provides that Johns Manville will not, prior to the
consummation of the merger, and without prior written consent of the Manville
Trust:

     - amend the merger agreement or extend the time for the performance of the
       terms of the merger agreement or waive any conditions to the merger
       agreement; or

     - permit the merger to occur if the Manville Trust has executed the
       stockholders agreement and HB Merger LLC, Hicks, Muse or Bear Stearns has
       not done so.

     In addition, Johns Manville waives any rights of first refusal that it may
be entitled to under the supplemental agreement between Johns Manville and the
Manville Trust in connection with the issuance of class TM preferred stock to
the Manville Trust pursuant to the exchange agreement, the conversion of the
Manville Trust's shares of Johns Manville common stock and class TM preferred
stock pursuant to the merger agreement, and the merger.
                                       77
<PAGE>   87

     The letter agreement provides that the Manville Trust will execute the
stockholders agreement prior to the consummation of the merger. The Manville
Trust also agrees that:

     - if the merger agreement is terminated because the voting agreement has
       been terminated because the Manville Trust has entered into a superior
       stockholder proposal, then the Trust will reimburse to Johns Manville the
       expenses and termination fee that Johns Manville must pay to HB Merger
       LLC or HB Finance LLC under the merger agreement. However, Johns Manville
       will reimburse the Manville Trust if Johns Manville (1) enters into an
       acquisition proposal within one year after the termination of the merger
       agreement with a per share value to the stockholders greater than the per
       share value of the consideration in the merger agreement or (2) the
       superior stockholder proposal is made available to all Johns Manville
       stockholders and more than 90% of the outstanding shares of Johns
       Manville common stock are actually acquired; and

     - if the merger agreement is terminated (1) due to failure to receive U.S.
       bankruptcy court approval, or (2) by HB Merger LLC because Johns
       Manville, due to actions attributable solely to the Manville Trust or its
       trustees, continues to engage in negotiations relating to another
       acquisition proposal beyond a period of 45 days permitted under the
       merger agreement, then the Manville Trust will pay to Johns Manville the
       expenses and termination fee that Johns Manville must pay to HB Merger
       LLC under the merger agreement. However, Johns Manville will repay that
       amount to the Manville Trust if (1) the superior stockholder proposal is
       available to all Johns Manville stockholders and more than 90% of the
       outstanding shares of Johns Manville are acquired; (2) Johns Manville
       enters into an agreement for an acquisition proposal which treats other
       stockholders at least as favorably as the Trust, or (3) Johns Manville
       shall have consummated an acquisition proposal. In addition, the Manville
       Trust will reimburse Johns Manville for any termination fee payable in
       the foregoing circumstances unless the Trust would be entitled to
       repayment of the amount of expenses it reimbursed to Johns Manville.

STOCKHOLDERS AGREEMENT

     Johns Manville, the Manville Trust, some members of management of Johns
Manville and affiliates of each of Hicks, Muse and Bear Stearns will enter into
a stockholders' agreement for the surviving corporation prior to the closing
under the merger agreement, and it will be effective after the closing.

     The stockholders agreement provides that the board of directors of the
surviving corporation will consist of a total of nine members, including the
chief executive officer of the surviving corporation and appointees designated
by the Hicks, Muse affiliate, the Bear Stearns affiliate and the Manville Trust.
The right of each of the Hicks, Muse affiliate, the Bear Stearns affiliate and
the Manville Trust, collectively referred to as the controlling parties, to
appoint members to the board of directors will terminate upon the occurrence of
certain events.

     The Hicks, Muse affiliate generally has the right to request a sale of the
surviving corporation, and the parties to the stockholders' agreement have
agreed to vote their shares of stock in favor of such a sale to the extent
necessary to effect consummation of the sale.

     The controlling parties have the right to make demand requests for
registration of certain securities held by each of them and any non-demanding
party may be included in the demand registration, subject to a pro rata cutback
of shares registered if the inclusion of all shares would materially and
adversely affect the offering. Some parties to the stockholders' agreement also
have the right to request an S-3 registration or a shelf registration of their
surviving corporation common stock and surviving corporation junior preferred
stock.

     The stockholders agreement contains registration rights regarding shares,
preemptive rights and rights in some circumstances to require other stockholders
to sell shares or to permit other stockholders to participate in a share sale.
The Hicks, Muse affiliate is the only holder which can exercise the right to
require other stockholders to sell shares if the Hicks, Muse affiliate is
selling shares.

                                       78
<PAGE>   88

     A majority of the stockholders have to approve some transactions entered
into by the surviving corporation. These rights are eliminated when the
surviving corporation is not achieving certain financial thresholds but will be
reinstated when the financial thresholds are met.

     The Bear Stearns affiliate has the right to demand the surviving
corporation to effect an initial public offering of its shares five years after
the effective date of the stockholders' agreement if an initial public offering
has not yet been consummated. Prior to effecting such an initial public
offering, the Hicks, Muse affiliate may cause the surviving corporation to be
sold.

     The surviving corporation has call rights with respect to shares held by
members of management who are parties to the stockholders' agreement, with the
price determined by the surviving corporation board of directors.

     At any time that the most junior publicly traded debt security of the
surviving corporation achieves investment grade rating, the Manville Trust can
request the Hicks, Muse affiliate and the Bear Stearns affiliate to assist it in
the sale of all shares held by the Manville Trust to a third person.

     The stockholders agreement will terminate upon the tenth anniversary of the
closing under the merger agreement. Some provisions of the stockholders'
agreement will terminate upon consummation of an initial public offering.

HOLDBACK AGREEMENT

     In a separate letter agreement between the Manville Trust and Bear Stearns
Corporate Lending, an affiliate of Bear Stearns Merchant Fund Corp., the
Manville Trust agreed that it will not, without the prior written consent of
Bear Stearns Corporate Lending, which consent may be withheld at its sole
discretion, sell, offer or agree to sell, or otherwise dispose of, directly or
indirectly, any of its shares of pay-in-kind preferred stock that the Manville
Trust owns after the merger, or any shares of pay-in-kind preferred stock that
the Manville Trust acquires after the merger, or any securities convertible
into, exercisable for or exchangeable for pay-in-kind preferred stock or engage
in any hedging or any other derivatives transactions in or relating directly to
shares of pay-in-kind preferred stock or publicly announce the intention to do
any of these transactions, for a period of up to 180 days following the
consummation of the merger.

DESCRIPTION OF THE CAPITAL STOCK FOLLOWING AMENDMENT TO RESTATED CERTIFICATE OF
INCORPORATION

     If the amendment to the restated certificate of incorporation is approved
and the merger agreement is adopted, then prior to the closing under the merger
agreement, the restated certificate of incorporation will be amended by the
filing of a certificate of amendment eliminating the series A preferred stock
and series

                                       83
<PAGE>   93

B preferred stock, and authorizing the class TM preferred stock, par value $0.01
per share. Article Fourth of the Johns Manville restated certificate of
incorporation will be amended to authorize, designate the rights, preferences,
privileges, restrictions and other matters thereof, and issue up to 5,000,000
shares of class TM preferred stock.

  Class TM Preferred Stock

     Designation and Amount. The class TM preferred stock will have a par value
of $0.01 per share. The authorized number of shares of class TM preferred stock
will be 5,000,000.

     Rank. With respect to dividends and distributions upon the liquidation,
winding-up and dissolution, the class TM preferred stock will rank senior to all
classes of Johns Manville common stock, and to each other class of capital stock
or series of preferred stock hereafter created by the Johns Manville board, the
terms of which do not expressly provide that it ranks senior to or pari passu
with the class TM preferred stock as to dividends or distributions upon the
liquidation, winding-up and dissolution of Johns Manville. The class TM
preferred stock shall, with respect to dividends and distributions upon the
liquidation, winding-up and dissolution of Johns Manville, rank pari passu with
any class of capital stock or series of preferred stock hereafter created by the
Johns Manville board, the terms of which expressly provide that it ranks pari
passu with the class TM preferred stock as to dividends and distributions upon
the liquidation, winding-up and dissolution of Johns Manville.

     Dividends. The holders of shares of class TM preferred stock will be
entitled to receive dividends and distributions in an amount and at the time
payable as any dividends and distributions that are declared on the Johns
Manville common stock, as if each share of class TM preferred stock were equal
to one share of common stock.

     Voting Rights. Each share of class TM preferred stock shall entitle the
holder to one vote on all matters submitted to a vote of the Johns Manville
stockholders. Except as required by law, the holders of shares of class TM
preferred stock and the holders of shares of common stock will vote together as
one class on all matters submitted to a vote of Johns Manville stockholders. Any
amendment, alteration or exchange or similar transaction of any of the
provisions of the restated certificate of incorporation of Johns Manville which
would alter or change the powers, preferences or special rights of the shares of
class TM preferred stock so as to adversely affect them will require the
affirmative vote of the holders of a majority of the outstanding shares of class
TM preferred stock, voting separately as a class. Except as required by law,
holders of class TM preferred stock shall have no special voting rights and
their consent as a class shall not be required for taking any corporate action.

     Reacquired Shares. Any shares of class TM preferred stock purchased or
otherwise acquired by Johns Manville in any manner (including by
reclassification) will be retired and cancelled promptly after such acquisition.
All such shares shall, upon their retirement, become authorized but unissued
shares of preferred stock without designation as to series and may be reissued
as part of a new series of preferred stock to be created by resolution or
resolutions of the Johns Manville board or as otherwise permitted under the
Delaware law.

     Liquidation, Dissolution or Winding Up. Upon any liquidation, dissolution
or winding up of Johns Manville, no distribution shall be made (1) to the
holders of shares of stock ranking junior (either as to dividends or upon
liquidation, dissolution or winding up) to the class TM preferred stock unless,
prior thereto, the holders of shares of class TM preferred stock shall have
received $15.625 per share, or (2) to the holders of stock ranking on a parity
(either as to dividends or distributions upon liquidation, dissolution or
winding up) with the class TM preferred stock, except distributions made ratably
on the class TM preferred stock and all other such parity stock in proportion to
the total amounts to which the holders of all such shares are entitled as to
dividends or upon such liquidation, dissolution or winding up. Neither the sale,
lease, conveyance, exchange or transfer (for cash, shares of stock, securities
or other consideration) of all or substantially all of the property or assets of
Johns Manville nor the consolidation or merger of Johns Manville with or into
one or more corporations will be considered to be a liquidation, dissolution or

                                       84
<PAGE>   94

winding-up of the affairs of Johns Manville (unless such sale, conveyance,
exchange or transfer is in connection with a dissolution or winding up of the
business of Johns Manville).

     Redemption. The shares of class TM preferred stock are not redeemable.

     Conversion Rights. The shares of class TM preferred stock will be
automatically converted into an equal number of validly issued, fully paid and
non-assessable shares of Johns Manville common stock in the event that the
merger is not consummated by the next business day after the transaction
contemplated by the exchange agreement is consummated. If the merger is not
consummated, or if the merger agreement is terminated, each holder of a
certificate representing class TM preferred stock will, after the earlier to
occur of such events, be entitled to receive certificates representing Johns
Manville common stock upon presentation of certificates representing class TM
preferred stock as provided for in the exchange agreement.

     Restriction on Transferability. Except as contemplated by the merger
agreement and the exchange agreement, the shares of class TM preferred stock may
not be transferred or pledged in any manner whatsoever.

     A form of the amendment to the restated certificate of incorporation for
Johns Manville containing the authorization and designation for the class TM
preferred stock is included as Appendix B to this proxy statement/prospectus.

DESCRIPTION OF THE CAPITAL STOCK FOLLOWING THE MERGER

  Authorized Capital Stock

     At the effective time of the merger, Johns Manville's restated certificate
of incorporation will be replaced by a new amended and restated certificate of
incorporation, referred to as the surviving corporation certificate of
incorporation. We have attached a copy of the surviving corporation certificate
of incorporation as Appendix H to this proxy statement/prospectus. The surviving
corporation will have the authority to issue 70,000,000 shares, of which
40,000,000 shares will be surviving corporation common stock, par value $0.01
per share and 30,000,000 shares will be surviving corporation preferred stock,
par value $0.01, with 8,000,000 shares designated as series A redeemable
pay-in-kind preferred stock, referred to as the pay-in-kind preferred stock, and
16,000,000 shares designated as series B convertible preferred stock, referred
to as the junior preferred stock. We have attached a copy of the certificate of
designations for the pay-in-kind preferred stock as Appendix G to this proxy
statement/prospectus.

     The surviving corporation board of directors will have authority to issue
one or more series of surviving corporation preferred stock within the limits
and restrictions of the surviving corporation certificate of incorporation
including determining the number of shares of any series, dividend rights,
redemption rights, special and relative rights, conversion rights, terms of any
sinking fund voting powers, limitations and such other preference or powers as
the surviving corporation board of directors shall determine.

  Surviving Corporation Common Stock

     Voting Rights. Each holder of surviving corporation common stock is
entitled to one vote for each share held and, except as otherwise provided by
law or by the surviving corporation board of directors with respect to any
series of surviving corporation preferred stock, the holders of surviving
corporation common stock will exclusively possess all voting power. Holders of
surviving corporation common stock are not entitled to accumulate votes for the
election of directors.

     Preemptive Rights. The surviving corporation common stock is not entitled
to conversion or preemptive rights and is not subject to redemption or
assessment.

     Dividend Rights. Subject to the rights of holders of any outstanding
surviving corporation preferred stock, the holders of outstanding shares of
surviving corporation common stock are entitled to share ratably

                                       85
<PAGE>   95

in dividends declared out of assets legally available therefor at such time and
in such amounts as the surviving corporation board of directors may from time to
time lawfully determine.

     Rights Upon Liquidation. Subject to the rights of holders of any
outstanding surviving corporation preferred stock, upon liquidation, dissolution
or winding up of surviving corporation, any assets legally available for
distribution to stockholders as such are to be distributed ratably among the
holders of the surviving corporation common stock at that time outstanding.

     The surviving corporation common stock is not immediately expected to be
listed on any exchange.

  Pay-in-Kind Preferred Stock

     Liquidation Preference. Each full share of pay-in-kind preferred stock will
have a liquidation preference of $100, meaning that in the event that the
surviving corporation is liquidated, dissolved or wound up, holders of a full
share of pay-in-kind preferred stock will be entitled to be paid the liquidation
preference of $100 per share of pay-in-kind preferred stock plus accumulated and
unpaid dividends. You, as a holder of pay-in-kind preferred stock, will not be
entitled to any further payment in the event of liquidation.

     Rank. The pay-in-kind preferred stock will rank, with respect to dividends
and distributions on liquidation, as follows:

     - senior to the surviving corporation common stock and junior preferred
       stock;

     - senior to each other class of capital stock or series of preferred stock
       created after the merger, the terms of which do not expressly provide
       that it ranks senior to, or pari passu with, the pay-in-kind preferred
       stock;

     - pari passu with any class of capital stock or series of preferred stock
       created after the merger, the terms of which expressly provide that it
       ranks pari passu with the pay-in-kind preferred stock; and

     - junior to each class of capital stock or series of preferred stock
       created after the merger, which has been approved by the holders of the
       pay-in-kind preferred stock, and the terms of which expressly provide
       that it ranks senior to the pay-in-kind preferred stock, provided that no
       such approval is necessary with respect to liquidation preference or
       stated amount of shares of capital stock of Johns Manville or its
       subsidiaries, including any pay-in-kind dividends paid thereon, issued in
       lieu of up to $600,000,000 initial proceeds from the sale of debt
       securities in connection with the first refinancing thereof.

     Dividends. The holders of shares of pay-in-kind preferred stock are
entitled to receive cumulative dividends (when, and if, declared by the
surviving corporation board of directors) at a rate of 13.0% per year, payable
in cash twice a year. Before the seventh anniversary of the effective time of
the merger, the surviving corporation may, at its option, issue, as dividends,
shares of pay-in-kind preferred stock with an aggregate liquidation preference
equal to the amount of the dividends to be paid. All undeclared dividends and
declared but unpaid dividends compound on a semi-annual basis at 13.0% per annum
subject to adjustment until the dividends are actually paid. If the surviving
corporation fails to redeem the pay-in-kind preferred stock on the scheduled
redemption date, or there occurs a change of control of surviving corporation
and it fails to redeem the pay-in-kind preferred stock, the dividend rate will
be increased to 15.0% per annum.

     Scheduled Redemption. To the extent that surviving corporation has funds
legally available for redemption of the pay-in-kind preferred stock, each
outstanding share of pay-in-kind preferred stock shall be redeemed by surviving
corporation on the twelfth anniversary of the date that the merger becomes
effective. The redemption will be at the liquidation preference, plus accrued
and unpaid dividends, if any, up to the date of redemption.

     Optional Redemption. All outstanding shares of pay-in-kind preferred stock
shall be redeemable at the option of surviving corporation, at any time, in
whole or in part, at the following prices (expressed as
                                       86
<PAGE>   96

percentages of the liquidation preference) plus accrued and unpaid dividends up
to the date of redemption, if redeemed during the following periods as indicated
below:

Thereafter                                                          100.0%
</TABLE>

     Change in Control. In the event of a change in control, upon the vote or
consent to that of a majority of the outstanding shares of pay-in-kind preferred
stock, the surviving corporation will be obligated to redeem the holder's shares
of pay-in-kind preferred stock at 101% of the liquidation preference of the
pay-in-kind preferred stock, in cash, plus any accrued and unpaid dividends.

     A change in control of the surviving corporation arises if:

     - a single holder, other than the initial holders of surviving corporation
       common stock, which includes the Manville Trust, the Hicks, Muse/Bear
       Stearns group and some members of management, of surviving corporation
       common stock immediately following the merger, acquires more than 50% of
       the outstanding shares of surviving corporation common stock, or

     - someone other than one of the initial holders acquires more surviving
       corporation common stock shares than the number held by the initial
       holders and their affiliates

     No Right of Conversion. The holders of pay-in-kind preferred stock will not
have any conversion rights.

     Voting Rights. In the event of any of the circumstances described below,
the holders of pay-in-kind preferred stock will be entitled to elect two
additional directors to serve on the surviving corporation board of directors.
The holders of shares of pay-in-kind preferred stock are only entitled to these
voting rights in the following circumstances:

     - if three dividends on the pay-in-kind preferred stock have not been paid;

     - if any bankruptcy or insolvency or similar proceedings is commenced by or
       against surviving corporation (if an involuntary proceeding, only if such
       proceeding remains undismissed or unstayed for sixty days);

     - if, for any reason, the surviving corporation has failed to redeem on the
       scheduled redemption date or upon the occurrence of a change in control;
       or

     - if the surviving corporation shall have failed to comply in any material
       respect with any of the covenants of the terms of the pay-in-kind
       preferred stock, and this failure continues for a period of thirty days.

     The right to elect two directors will be reduced to a right to elect one
director if the liquidation preference of the outstanding pay-in-kind preferred
stock is 50% or less of the aggregate liquidation preference of pay-in-kind
preferred stock issued until that time, or the amount of outstanding liquidation
preference of pay-in-kind preferred stock as of the time of the event is
thereafter reduced by 50% or more. The right to elect directors will cease when
the event permitting election has been cured, and the term of office of one
director so elected will then expire.

     The surviving corporation's certificate of incorporation may not be amended
so as to adversely affect the specified rights of the pay-in-kind preferred
stock without the approval of the holders of a majority of the outstanding
shares of pay-of-kind preferred stock.

     Covenants and Restrictions. So long as any shares of pay-in-kind preferred
stock remain outstanding, the surviving corporation may not without the consent
or approval of a majority of the outstanding shares of pay-in-kind preferred
stock, amend, alter or repeal any provision of the surviving corporation
certificate of incorporation so as to adversely affect the specified rights of
the pay-in-kind preferred stock (and any amendment that reduces the dividend
payable on, or the liquidation preference of, the pay-in-kind preferred stock
shall require the approval of each holder of pay-in-kind preferred stock
adversely affected). In addition, without such consent or approval, except with
respect to such liquidation preference or stated amount of shares of capital
stock of Johns Manville or its subsidiaries (including any pay-in-kind dividends
paid thereon) as shall be issued in lieu of up to $600,000,000 of initial
proceeds from the sale of debt securities in connection with the financing of
the merger and the first financing of the merger and the first refinancing
thereof, the surviving corporation may not:

     - create, authorize or issue any capital stock senior to the pay-in-kind
       preferred stock;

     - issue any capital stock pari passu with the pay-in-kind preferred stock
       to any affiliate of the surviving corporation or its officers or
       directors;

     - issue any capital stock pari passu with the pay-in-kind preferred stock
       so long as the Manville Trust owns a majority of the outstanding shares
       of pay-in-kind preferred stock, other than up to $150,000,000 in initial
       liquidation preference of preferred stock (excluding pay-in-kind
       dividends) and on which the surviving corporation may not pay cash
       dividends unless cash dividends are then being paid on the pay-in-kind
       preferred stock;

     - issue any capital stock with a scheduled redemption date prior to the
       twelfth anniversary of the merger, or redeem or make payment on capital
       stock following such date if the pay-in-kind preferred stock has not been
       redeemed in full;

     - declare or pay dividends or distributions on any shares of securities
       junior to the pay-in-kind preferred stock;

     - declare or pay dividends or distribution on parity securities except (A)
       dividends on up to $150,000,000 initial liquidation preference of
       preferred stock referred to above and (B) dividends paid ratably on such
       securities, the pay-in-kind preferred stock and all other parity
       securities;

     - redeem or purchase any securities junior to the pay-in-kind preferred
       stock;

     - redeem or purchase parity securities except in accordance with an offer
       to all parity security holders on terms determined by the surviving
       corporation board of directors to be fair and equivalent;

     - permit any subsidiary to purchase any shares of the capital stock of the
       surviving corporation unless the surviving corporation could do so;

     - permit any subsidiary to redeem any equity securities of any subsidiary
       for cash or non-permitted securities or issue any equity securities to
       any person other than issuance to persons other than affiliates of the
       surviving corporation or its officers or directors of equity securities
       which do not provide for the payment of dividends (other than permitted
       equity dividends) or mandatory redemption when shares of pay-in-kind
       preferred stock are outstanding (other than for redemption payments made
       in permitted equity securities), or pay any dividend on equity securities
       in cash or other property (other than payment in permitted equity
       securities);

     - allow any encumbrance or restrictions on the ability of any of its wholly
       owned subsidiaries to: pay dividends on or in respect of its capital
       stock to the surviving corporation or any subsidiary; make loans or
       advances to the surviving corporation or any subsidiary; or transfer any
       of its properties or assets to the surviving corporation or any
       subsidiary, other than pursuant to applicable law and arrangements
       enumerated in the certificate of designations, including any agreement
       evidencing indebtedness of the surviving corporation or its subsidiaries;
       and

                                       88
<PAGE>   98

     - except as permitted under the arrangement governing the merger financing
       and the first refinancing thereof, permit any of its subsidiaries to make
       any payment to, or dispose of any of its properties or assets to, or
       purchase any property or assets from, or enter into or make or amend any
       transaction with, or for the benefit of, any affiliate of the surviving
       corporation, unless such affiliate transaction shall have been approved
       by a majority of the members of the surviving corporation board of
       directors, provided that if such affiliate transaction involves
       consideration in excess of $10,000,000, it must be determined by a
       majority of the surviving corporation board of directors to be at least
       as favorable as those that might reasonably have been obtained in a
       comparable arms'-length transaction with an unaffiliated party.

  Junior Preferred Stock

     Liquidation Preference. Each share of junior preferred stock will have a
liquidation preference of $15.625, meaning that in the event that the surviving
corporation is liquidated, dissolved or wound up, holders of a share of junior
preferred stock will be entitled to be paid the liquidation preference of
$15.625 per share of junior preferred stock before any distribution is made to
the holders of shares of any other junior securities or the common stock. In
addition, in the event of liquidation, dissolution or winding up, no
distribution shall be made to the holders of parity securities (either as to
dividends or distributions upon liquidation) and common stock (as to dividends),
except distributions made ratably on the junior preferred stock and all other
parity securities or common stock. Holders of junior preferred stock will not be
entitled to any further payment in the event of liquidation.

     Rank. The junior preferred stock will rank, with respect to dividends and
distributions on liquidation, as follows:

     - senior to the surviving corporation common stock (pari passu with the
       surviving corporation common stock with respect to dividends);

     - senior to each other class of capital stock or series of preferred stock
       created after the merger, the terms of which do not expressly provide
       that it ranks senior to or pari passu with the junior preferred stock;

     - pari passu with each other class of capital stock or series of preferred
       stock created after the merger, the terms of which expressly provide that
       it ranks pari passu with the junior preferred stock; and

     - junior to the pay-in-kind preferred stock and to any other class of
       capital stock or series of preferred stock created after the merger, the
       terms of which expressly provide that it ranks senior to the junior
       preferred stock.

     Dividends. The holders of shares of junior preferred stock are entitled to
receive dividends or distributions when, as and if dividends are declared by the
surviving corporation board of directors and paid on the surviving corporation
common stock payable with respect to each share of junior preferred stock as if
each share were converted into the number of shares of common stock into which
such share of junior preferred stock would be converted if such share was
converted immediately prior to the record date for such dividend.

     Scheduled Redemption. To the extent that surviving corporation has funds
legally available for redemption of the junior preferred stock, each outstanding
share of junior preferred stock will be redeemed by surviving corporation on the
date which is six months after the twentieth anniversary of the date of issuance
of the junior preferred stock at $15.625 per share.

     Optional Redemption. All outstanding shares of junior preferred stock will
be redeemable at the option of surviving corporation, at any time in whole or in
part at $15.625 per share of junior preferred stock.

                                       89
<PAGE>   99

     Change in Control. In the event of a change in control of the surviving
corporation, the holders of a majority of the outstanding shares of junior
preferred stock may require the surviving corporation to redeem the holder's
shares of junior preferred stock at 100% of the liquidation preference of the
junior preferred stock, in cash, provided, however, that in order for surviving
corporation to effect the redemption, no shares of pay-in-kind preferred stock
may be outstanding, and if so, the redemption will be deferred until a time that
no shares of pay-in-kind preferred stock are outstanding.

     A change in control of the surviving corporation arises if:

     - a single holder, other than the initial holders of surviving corporation
       common stock, which includes the Manville Trust, the Hicks, Muse/Bear
       Stearns group and some members of management, of surviving corporation
       common stock immediately following the merger, acquires more than 50% of
       the outstanding shares of surviving corporation common stock, or

     - someone other than one of the initial holders acquires more surviving
       corporation common stock shares than the number held by the initial
       holders and their affiliates.

     Optional Conversion. Each outstanding share of junior preferred stock will
be converted into, subject to adjustment, one fully paid and non-assessable
share of surviving corporation common stock if the holders of a majority of the
outstanding shares of junior preferred stock, voting as a class, approve the
conversion. The holders of junior preferred stock may also elect, from time to
time, to require a partial conversion of the shares of junior preferred stock
then outstanding.

     Mandatory Conversion. All outstanding shares of junior preferred stock
shall automatically be converted into one fully paid and non-assessable share of
surviving corporation common stock at the time the surviving corporation
consummates a "qualified initial public offering," in which the aggregate per
share offering price is at least $15.625 per share (subject to equitable
adjustment); provided, however, that outstanding shares of junior preferred
stock will not be converted if shares of junior preferred stock shall have been
called for redemption pursuant to the terms of the junior preferred stock on or
prior to the date of consummation of a "qualified initial public offering" and
provided further that, the unconverted shares of junior preferred stock shall
nevertheless automatically be converted on the date that the applicable
redemption payment is due pursuant to the terms of the junior preferred stock if
and to the extent that the redemption payment is not made.

     A "qualified initial public offering" means one or a series of firm
commitment underwritten public offerings of newly issued common stock pursuant
to a registration statement under the 1933 Act, where the proceeds to the
surviving corporation equal or exceeds $100,000,000 and upon consummation of
such offering or offerings, the common stock is listed on the New York Stock
Exchange or American Stock Exchange or authorized to be traded on the Nasdaq
National Market.

     Voting Rights. Each holder of a share of junior preferred stock is entitled
to vote, on all matters submitted to a vote of the stockholders of surviving
corporation, the number of votes equal to the number of shares of common stock
of the surviving corporation into which such share would be converted if
converted immediately prior to the record date for such vote. The holders of
shares of junior preferred stock vote together with the holders of shares of
common stock as one class on all matters submitted to a vote of stockholders
except as required by law.

     In addition, as long as any shares of junior preferred stock remain
outstanding, without the written consent or approval at a meeting called for
such purpose of the holders of at least 85% of the outstanding shares of junior
preferred stock, surviving corporation shall not amend, alter or repeal any
provision of the amended and restated certificate of incorporation of the
surviving corporation relating to the junior preferred stock so as to adversely
affect the rights of the junior preferred stock. Any amendment that reduces the
liquidation preference of the junior preferred stock requires the approval of
each holder of junior preferred stock adversely affected by such amendment.

          (b) Each issued and outstanding share of Class TM Preferred Stock, the
     terms of which are set forth in Exhibit A hereto shall be converted at the
     Effective Time into the right to receive, payable upon surrender of the
     certificate or certificates which immediately prior to the Effective Time
     represented issued and outstanding shares of Class TM Preferred Stock (the
     "Class TM Certificates") in the manner provided in Section 2.2, 0.6 of a
     fully paid and nonassessable share of common stock of the Surviving
     Corporation (the "Surviving Corporation Common Stock") and 0.4 of a fully
     paid and nonassessable share of Series B Junior Redeemable Convertible
     Preferred Stock, par value $.01 per share, of the Surviving Corporation,
     the terms of which are set forth in Annex B to Exhibit B hereto (the
     "Surviving Corporation Junior Preferred Stock"). Such consideration is
     referred to herein as the "Class TM Merger Consideration", and references
     to such consideration or the Common Stock Merger Consideration, as
     applicable, are referred to hereby as the "Merger Consideration". All such
     Class TM Shares, when so converted, shall no longer be outstanding and
     shall automatically be cancelled and retired and shall cease to exist, and
     each holder of a Class TM Certificate shall cease to have any rights with
     respect thereto, except the right to receive the Class TM Merger
     Consideration for each share of Class TM Preferred Stock upon the surrender
     of the Class TM Certificates in accordance with Section 2.2. Any payment
     made pursuant to this Section 2.1(b) shall be made net of applicable
     withholding taxes to the extent such withholding is required by law.

          (c) Each issued and outstanding Merger Company Membership Interest
     shall be converted into and become 0.6 of a fully paid and nonassessable
     share of Surviving Corporation Common Stock and 0.4 of a fully paid and
     nonassessable share of Surviving Corporation Junior Preferred Stock.

          (d) All shares of Company Common Stock that are held by the Company as
     treasury stock and all shares of Company Common Stock owned by Merger
     Company or any Subsidiary of Merger Company shall be cancelled and retired
     and shall cease to exist and no Merger Consideration shall be delivered in
     exchange therefor.

     SECTION 2.2  Exchange of Certificates.

     (a) At least five Business Days prior to the Effective Time, Merger Company
shall designate the Company's registrar and transfer agent, or such other bank
or trust company as is reasonably satisfactory to the Company, to act as
exchange agent for the holders of Common Shares and Class TM Shares
(collectively, the "Shares") in connection with the Merger, pursuant to an
agreement providing for the matters set forth in this Section 2.2 and such other
matters as may be appropriate and the terms of which are reasonably satisfactory
to the Company (the "Exchange Agent"), for the payment of the applicable Merger
Consideration. Immediately prior to the Effective Time, Finance Company and the
Company will cause to be deposited in trust with the Exchange Agent for the
benefit of holders of the Shares, as applicable, (i) the amount of cash, (ii)
certificates representing the number of whole shares of Surviving Corporation
Preferred Stock, (iii) certificates representing the number of whole shares of
Surviving Corporation Junior Preferred Stock and (iv) certificates representing
the number of whole shares of Surviving Corporation Common Stock necessary to
complete the transactions contemplated by this Section 2.2 on a timely basis
(the "Exchange Fund").

     At the Effective Time, the Surviving Corporation will instruct the Exchange
Agent to promptly, and in any event not later than three Business Days following
the Effective Time, mail (and to make available for collection by hand) to each
holder of record of Common Stock Certificates or Class TM Certificates
(collectively, the "Certificates"), whose shares were converted pursuant to
Section 2.1 into the right to receive the applicable Merger Consideration (i) a
letter of transmittal (which shall specify that delivery shall be effected, and
risk of loss and title to such Certificates shall pass, only upon delivery of
such Certificates to the Exchange Agent and shall be in such form and have such
other provisions as Merger Company and the Company may reasonably specify) and
(ii) instructions for use in effecting the

                                       A-3
<PAGE>   121

surrender of the Certificates in exchange for payment of the applicable Merger
Consideration (which shall provide that, at the election of the surrendering
holder, Certificates may be surrendered, and the applicable Merger Consideration
therefor collected, by hand delivery). At least two Business Days prior to the
Effective Time, Merger Company will cause the Exchange Agent to make available
for collection by hand at its offices in New York, New York, the letter of
transmittal and instructions referred to in the immediately preceding sentence.
Upon surrender of a Certificate for cancellation to the Exchange Agent or to
such other agent or agents as may be appointed by the Company, together with
such letter of transmittal, duly executed, the holder of such Certificate shall
be entitled to receive in exchange therefor the applicable Merger Consideration
for each share of Company Common Stock or Class TM Preferred Stock, as the case
may be, formerly represented by such Certificate, to be mailed within three
Business Days of receipt thereof (and made available for collection by hand
immediately following the Effective Time if the completed letter of transmittal
is received at least one Business Day prior to the Effective Time), and the
Certificate so surrendered shall forthwith be cancelled. If payment of the
applicable Merger Consideration is to be made to a person or stock certificates
are to be issued to a person other than the person in whose name the surrendered
Certificate is registered, it shall be a condition of payment or issuance that
the Certificate so surrendered shall be properly endorsed or shall be otherwise
in proper form for transfer and that the person requesting such payment shall
have paid any transfer and other taxes required by reason of the payment of the
applicable Merger Consideration to a person other than the registered holder of
the Certificate surrendered or shall have established to the satisfaction of the
Surviving Corporation that such tax either has been paid or is not applicable.
In the event of a transfer of ownership of Company Common Stock which is not
registered in the transfer records of the Company, the applicable Merger
Consideration and a check in the proper amount of cash in lieu of any fractional
shares of Surviving Corporation Preferred Stock pursuant to Section 2.2(d) and
any dividends or other distributions to which such holder is entitled, may be
issued with respect to such Company Common Stock to such a transferee if the
Certificates representing such Company Common Stock are presented to the
Exchange Agent (or if lost, stolen or destroyed, the procedures set forth in
Section 2.2(e) are complied with), accompanied by all documents required to
evidence and effect such transfer and to evidence that any applicable stock
transfer taxes have been paid.

     (b) Until surrendered as contemplated by this Section 2.2, each Certificate
(other than Certificates representing Company Common Stock held by Merger
Company, or any Subsidiary of Merger Company, or Dissenting Shares (as defined
in Section 2.4)) shall be deemed at any time after the Effective Time to
represent only the right to receive the applicable Merger Consideration as
contemplated by this Section 2.2. No interest or dividends shall be paid or will
accrue on any Merger Consideration payable to holders of Certificates pursuant
to the provisions of this Article II (other than dividends, if any, accruing on
the Surviving Corporation Preferred Stock, Surviving Corporation Junior
Preferred Stock or Surviving Corporation Common Stock from the Effective Time
pursuant to the terms thereof).

     Notwithstanding the foregoing, neither the Exchange Agent nor any party
hereto shall be liable to a holder of any such shares for any Surviving
Corporation Preferred Stock, Surviving Corporation Junior Preferred Stock or
Surviving Corporation Common Stock or dividends thereon, or, in accordance with
Section 2.2(d), cash in lieu of fractional shares thereof, delivered to a public
official pursuant to applicable escheat law. The Exchange Agent shall not be
entitled to vote or exercise any rights of ownership with respect to the
Surviving Corporation Preferred Stock, Surviving Corporation Junior Preferred
Stock or Surviving Corporation Common Stock held by it from time to time
hereunder, except that it shall receive and hold all dividends or other
distributions paid or distributed with respect to such Surviving Corporation
Preferred Stock, Surviving Corporation Junior Preferred Stock and Surviving
Corporation Common Stock for the account of the persons entitled thereto.

     (c) Any portion of the Exchange Fund and the Fractional Securities Fund (as
defined in Section 2.2(d)) which remains unclaimed by the former stockholders of
the Company for one year after the Effective Time shall be delivered to
Surviving Corporation, upon demand of Surviving Corporation, and any former
stockholders of the Company shall thereafter look only to Surviving Corporation
for payment of their claim for the Merger Consideration for the shares or for
any cash in lieu of fractional

                                       A-4
<PAGE>   122

shares of Surviving Corporation Preferred Stock, Surviving Corporation Junior
Preferred Stock or Surviving Corporation Common Stock.

     (d) No fractional shares of Surviving Corporation Preferred Stock,
Surviving Corporation Junior Preferred Stock or Surviving Corporation Common
Stock shall be issued in the Merger. Each holder of shares of Surviving
Corporation Preferred Stock, Surviving Corporation Junior Preferred Stock or
Surviving Corporation Common Stock to which such holder otherwise would have
been entitled pursuant to Section 2.2 (after taking into account all Shares then
held of record by such holder) shall receive in lieu thereof, a cash payment in
an amount equal to the product of (i) in the case of Surviving Corporation
Preferred Stock the fractional interest of each such share to which such holder
otherwise would have been entitled, multiplied by $100 and (ii) in the case of
Surviving Corporation Junior Preferred Stock or Surviving Corporation Common
Stock, as applicable, the fractional interest of each such share to which such
holder otherwise would have been entitled, multiplied by $15.625 (the cash
comprising such aggregate payments in lieu of such fractional shares being
hereinafter referred to as the "Fractional Securities Fund"). The Company shall,
immediately prior to the Effective Time, make available to the Exchange Agent
cash in an amount sufficient to make the payments in lieu of such fractional
shares as aforesaid.

     (e) In the event any Certificate shall have been lost, stolen or destroyed,
upon the making of an affidavit of that fact by the Person (as defined in
Section 8.5) claiming such Certificate to be lost, stolen or destroyed, the
Exchange Agent will issue in exchange for such lost, stolen or destroyed
Certificate the applicable Merger Consideration deliverable in respect thereof
as determined in accordance with this Article II, provided that the Person to
whom the Merger Consideration is paid shall, as a condition precedent to the
payment thereof, give the Surviving Corporation a bond in such sum as the
Surviving Corporation may direct or otherwise indemnify the Surviving
Corporation in a manner satisfactory to it against any claim that may be made
against the Surviving Corporation with respect to the Certificate claimed to
have been lost, stolen or destroyed.

     (f) After the Effective Time, the stock transfer books of the Company shall
be closed and there shall be no transfers on the stock transfer books of the
Surviving Corporation of shares of Company Common Stock and Class TM Preferred
Stock which were outstanding immediately prior to the Effective Time. If, after
the Effective Time, Certificates are presented to the Surviving Corporation,
they shall be cancelled and exchanged for the Merger Consideration as provided
in this Article II, subject to Section 262 of the DGCL.

     SECTION 2.3  Company Awards.

     (a) Immediately prior to the Effective Time, each outstanding option (each,
an "Option") to purchase shares of Company Common Stock (other than Elected
Management Options as defined in Section 2.3(c) below) and each outstanding
stock appreciation right with respect to Company Common Stock (each, an "SAR")
granted by the Company pursuant to the Company's benefit plans (the "Option
Plans") identified in Section 2.3 of the disclosure letter separately delivered
by the Company to Merger Company and Finance Company on or prior to the date
hereof (the "Disclosure Letter"), whether or not exercisable, which is
outstanding and unexercised at such time, shall be cancelled and each holder
thereof shall be entitled to receive, immediately prior to the Effective Time,
an amount in cash computed by multiplying (i) the excess, if any, of (A) the
greater of (x) $15.625 and (y) the highest Fair Market Value (as defined in the
Company's 1996 Executive Incentive Compensation Plan) per Common Share at any
time during the 60-day period preceding the Effective Time, over (B) the
exercise price per share of Company Common Stock subject to such Option or grant
price per share in respect of such SAR, as applicable (the "Spread"), by (ii)
the number of such shares of Company Common Stock then subject to such Option or
SAR; provided, that any such payment shall be net of all withholding taxes
required to be withheld by the Company.

     (b) Immediately prior to the Effective Time, each share of deferred stock
("Deferred Stock") awarded under the Option Plans (other than an Elected
Deferred Share as defined in Section 2.3(c) below) shall be cancelled and each
holder thereof shall be entitled to receive, immediately prior to the

                                       A-5
<PAGE>   123

Effective Time, with respect to each share of Deferred Stock so cancelled, an
amount in cash equal to the greater of (x) $15.625 and (y) the highest Fair
Market Value (as defined in the Company's 1996 Executive Incentive Plan) per
share of Company Common Stock at any time during the 60-day period preceding the
Effective Time (net of all withholding taxes required to be withheld by the
Company).

     (c) (i) Each member of Management (as defined in Section 8.5(iii)) shall
have the right to elect, prior to the Special Meeting, pursuant to an election
form reasonably acceptable to the parties ("Election Form"), that, in lieu of
receiving the Spread, with respect to each Option owned by such member of
Management for which an election is made, the Spread on such option will be
converted into the right to receive (i) that number of shares of Surviving
Corporation Common Stock equal to the product of (a) the Spread divided by
$15.625 and (b) 0.6 and (ii) that number of shares of Surviving Corporation
Junior Preferred Stock equal to the product of (x) the Spread divided by $15.625
and (y) 0.4, in each case on the terms and conditions set forth in the
applicable Election Form; provided, that any such payment shall be net of all
withholding taxes required to be withheld by the Company.

     (ii) Each member of Management shall have the right to elect, prior to the
Special Meeting, that, in lieu of receiving the corresponding cash payment as
set forth in Section 2.3(b) with respect to each share of Deferred Stock owned
by such member (each share for which an election is made, an "Elected Deferred
Share"), such Elected Deferred Share be converted into the Class TM Merger
Consideration, on the terms and subject to the conditions set forth in this
Section 2.3(c) and the applicable election form.

     (d) Immediately prior to the Effective Time, (i) each unit in the Company
Deferred Compensation Plan deemed invested in assets other than in Company
Common Stock shall be converted into the right to receive cash in an amount
equal to the value of such unit, payable to the holder thereof without interest,
and (ii) each unit deemed invested in shares of Company Common Stock in the
Deferral Account (as defined in the Company's Deferred Compensation Plan and the
Non-Employee Directors' Deferred Compensation Plan (together, the "Deferred
Compensation Plans") (together with the Option Plans, the "Benefit Plans")),
including those Deferral Accounts with respect to which one or more installment
payments have previously been made, shall be settled in a cash amount equal to
$15.625 per share provided that any such payment shall be net of all withholding
taxes required to be withheld by the Company. To the extent that, at the
Effective Time, a member of Management has any portion of his Deferral Account
deemed invested in shares of the Company Common Stock (the "Deemed Shares"),
such member shall have the right to elect, prior to the Special Meeting,
pursuant to an election form that, in lieu of receiving a cash payment set forth
in the Deferred Compensation Plan with respect to each Deemed Share owned by
such member (each, an "Elected Deemed Share"), that such Elected Deemed Share
will be converted into the Class TM Merger Consideration, on the terms and
subject to the conditions set forth in this Section 2.3(d) and the applicable
election form (net of all withholding taxes required to be withheld by the
Company).

     Notwithstanding anything in this Section 2.3 to the contrary, in no event
will the Company have an obligation hereunder that violates the terms of the
applicable Benefit Plans. Prior to the Effective Time, the Company shall use its
commercially reasonable efforts to (i) obtain all required consents from, and
provide any required notices to, the holders of Options and Deferred Stock and
(ii) amend the terms of the applicable Benefit Plans, in each case as is
necessary to give effect to the provisions of paragraphs (a), (b), (c) and (d)
of this Section 2.3; provided however, that the Company shall not be required to
make any payment in respect of the foregoing (other than as set forth in
Sections 2.3(a), (b), (c) and (d)).

     SECTION 2.4  Dissenter's Rights. Notwithstanding anything in this Agreement
to the contrary, Common Shares outstanding immediately prior to the Effective
Time and held by a holder who has not voted in favor of the Merger and who has
delivered a written demand for appraisal of such shares in accordance with
Section 262 of the DGCL, if such Section 262 provides for appraisal rights for
such Common Shares in the Merger ("Dissenting Shares"), shall not be converted
into the right to receive the Common Stock Merger Consideration, as provided in
Section 2.1 hereof, unless and until such holder fails to perfect or effectively
withdraws or otherwise loses his right to appraisal and payment under the DGCL.
If, after the Effective Time, any such holder fails to perfect or effectively
withdraws or loses his right to

                                       A-6
<PAGE>   124

appraisal, such Dissenting Shares shall thereupon be treated as if they had been
converted as of the Effective Time into the right to receive the Common Stock
Merger Consideration to which such holder is entitled, without interest or
dividends thereon (except dividends in respect of the Surviving Corporation
Preferred Stock).

                                  ARTICLE III

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     The Company represents and warrants to Merger Company and Finance Company
that:

     SECTION 3.1  Organization. Each of the Company and its Subsidiaries (as

a Material Adverse Effect (as defined in Section 8.5(iv)). The Company has
previously delivered to Merger Company a complete and correct copy of each of

Company may vote are issued or outstanding. All the outstanding shares of the
Company's capital stock are, and all shares of Class TM Preferred Stock and all
shares which may be issued or granted pursuant to the exercise of Options, SARs,

as of the date hereof and for the transactions contemplated hereby, there are no
existing (i) options, warrants, calls, pre-emptive rights, subscriptions or
other rights, convertible securities, agreements or commitments of any character

<PAGE>   125

(B) the aggregate number of securities or underlying securities associated
therewith and the price terms with respect to all other Options, SARs, Deferred
Stock or other such rights or obligations referred to in this Section 3.2(a).

     (b) Except as set forth in Section 3.2(b) of the Disclosure Letter, all of
the outstanding shares of capital stock (or equivalent equity interests of
entities other than corporations) of each of the Company's Subsidiaries are
beneficially owned, directly or indirectly, by the Company free and clear of any
mortgage, lien, pledge, charge, encumbrance or other security interest
(including any restriction on the right to vote, sell or otherwise dispose of
such capital stock or ownership interests) (collectively, "Liens"), other than
such restrictions as may exist under applicable statute and all such shares or
other ownership interests have been duly authorized, validly issued and are
fully paid and non-assessable.

     SECTION 3.3  Authorization; Validity of Agreement.

     (a) The Company has the requisite corporate power and authority to execute
and deliver this Agreement and, subject to approval of its stockholders as
contemplated by Section 5.6 hereof, to consummate the transactions contemplated
hereby. The execution and delivery by the Company of this Agreement and the
consummation of the transactions contemplated hereby have been duly approved and
authorized by the Board of Directors of the Company (the "Board") and, other
than adoption of this Agreement by the holders of a majority of the outstanding
shares of Company Common Stock, no other corporate proceedings on the part of
the Company are necessary to approve and authorize the execution and delivery of
this Agreement and approval of the Charter Amendment by the Company and the
consummation by it of the transactions contemplated hereby. This Agreement has
been duly executed and delivered by the Company and, assuming due authorization,
execution and delivery of this Agreement by Merger Company and Finance Company,
is a valid and binding obligation of the Company enforceable against the Company
in accordance with its terms, except that such enforcement may be subject to or
limited by (i) bankruptcy, insolvency or other similar laws, now or hereafter in
effect, affecting creditors' rights generally, and (ii) the effect of general
principles of equity (regardless of whether enforceability is considered in a
proceeding at law or in equity).

     (b) The Board has adopted such resolutions as are necessary so that the
provisions of Section 203 of the DGCL are inapplicable to the transactions
contemplated by this Agreement.

     SECTION 3.4  No Violations; Approvals.

     (a) Neither the execution and delivery of this Agreement by the Company nor
the consummation by the Company of the transactions contemplated hereby will (i)
violate any provision of the Restated Certificate of Incorporation or By-laws of
the Company or violate any provision of the certificate of incorporation or
bylaws (or other organizational documents with respect to non-incorporated
entities) of its Subsidiaries, (ii) except as set forth in Section 3.4(a) of the
Disclosure Letter, result in a violation or breach of, or constitute (with or
without due notice or lapse of time or both) a default (or give rise to any
right of termination, amendment, cancellation, acceleration or the creation of a
Lien, other than a Permitted Exception, pursuant to), or require any consent of
any third party pursuant to, any of the terms, conditions or provisions of any
material note, bond, mortgage, indenture, guarantee, other evidence of
indebtedness, lease, license, contract, collective bargaining agreement,
agreement or other instrument or obligation to which the Company or any of its
Subsidiaries is a party or by which any of them or any of their assets may be
bound or (iii) violate any order, writ, injunction, decree, statute, rule or
regulation applicable to the Company, any of its Subsidiaries or any of their
properties or assets; except in the case of clauses (ii) or (iii) for such
violations, breaches, defaults, rights, creation of Liens or failure to obtain
consents which would not have a Material Adverse Effect.

     (b) No filing or registration with, notification to, or authorization,
consent or approval of, any court, legislative, executive or regulatory
authority or agency (a "Governmental Entity") is legally required in connection
with the execution and delivery of this Agreement by the Company or the
consummation by the Company of the transactions contemplated hereby, except (i)
applicable requirements under Competition Laws (as defined in Section 5.4(c)),
(ii) with respect to the issuance of Surviving

                                       A-8
<PAGE>   126

Corporation Common Stock, Surviving Corporation Preferred Stock and Surviving
Corporation Junior Preferred Stock in the Merger, the applicable requirements
under the Securities Act of 1933, as amended (the "Securities Act"), (iii)
applicable requirements under the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), (iv) the filing of the Certificate of Merger with the
Secretary of State, including the amendments to the Restated Certificate of
Incorporation that will become effective as of the Effective Time set forth in
Exhibit B hereto, and the Charter Amendment, (v) applicable requirements under
corporation, takeover or "blue sky" laws of various states or non-United States
change-in-control or investment laws or regulations, (vi) applicable
requirements under Environmental Laws (as defined in Section 3.15) and (vii)
such other consents, approvals, orders, permits, authorizations, notifications,
registrations, declarations and filings the failure of which to be obtained or
made would not either individually, or in the aggregate, have a Material Adverse
Effect.

     SECTION 3.5  SEC Reports and Financial Statements. The Company has filed
with the Securities and Exchange Commission (the "SEC") all forms and documents
required to be filed by it since January 1, 1997 under the Exchange Act and has
heretofore made available to Merger Company (i) its Annual Reports on Form 10-K
for the years ended December 31, 1997, December 31, 1998 and December 31, 1999,
respectively, (ii) all proxy statements relating to meetings of stockholders of
the Company since January 1, 1997 (in the form mailed to stockholders), (iii)
its quarterly report on Form 10-Q for the quarter ended March 31, 2000, and (iv)
all other forms, reports and registration statements filed by the Company with
the SEC since January 1, 1997 (other than registration statements on Form S-8 or
preliminary materials and registration statements in forms not declared
effective). The documents described in clauses (i)-(iv) above, as amended, are
referred to in this Agreement collectively as the "Company SEC Documents". As of
their respective dates, the Company SEC Documents, including the financial
statements and schedules provided therein or incorporated by reference therein,
(a) did not contain any untrue statement of a material fact or omit to state a
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 and (b) complied in all material respects with the applicable
requirements of the Exchange Act and the Securities Act, as the case may be, and
the applicable rules and regulations of the SEC thereunder. The consolidated
financial statements included or incorporated by reference in the Company SEC
Documents have been prepared in accordance with United States generally accepted
accounting principles ("GAAP") applied on a consistent basis during the periods
involved (except as otherwise noted therein and except that the quarterly
financial statements are subject to year end adjustment and do not contain all
footnote disclosures required by GAAP) and fairly present in all material
respects the consolidated financial position and the consolidated results of
operations and cash flows of the Company and its consolidated Subsidiaries as at
the dates thereof or for the periods presented therein.

     SECTION 3.6  Absence of Certain Changes. Except as disclosed in the Company
SEC Documents or as disclosed in Section 3.6 of the Disclosure Letter, from
March 31, 2000 until the date of this Agreement, (i) the Company and its
Subsidiaries have conducted their operations in the ordinary course, (ii) there
has not been a Material Adverse Effect and (iii) the Company and its
Subsidiaries have not taken any of the following actions:

          (a) declared, set aside or paid (other than dividends paid by
     Subsidiaries to the Company or other wholly-owned Subsidiaries of the
     Company) any dividend or other distribution payable in cash, stock or
     property with respect to its capital stock, other than regular quarterly
     dividends consistent with past practice;

          (b) incurred any material indebtedness for money borrowed or issued or
     sold any debt securities or warrants or rights to acquire any debt

     SECTION 3.9  Employee Benefit Plans; ERISA.

     (a) Section 3.9(a) of the Disclosure Letter contains a true and complete
list of each material "employee benefit plan" as defined in Section 3(3) of
ERISA and each bonus, deferred compensation, incentive compensation, stock
purchase, stock option, stock award, severance or termination benefit,
hospitalization or other medical, life or other insurance, supplemental
unemployment benefits, profit-sharing, pension, or retirement plan, program,
agreement or arrangement, each employment, retention or severance agreement or
arrangement which cannot be terminated in fewer than three months or without
liability exceeding the greater of one month's salary or one week of salary for
each year of service and each other material employee benefit plan, program,
agreement or arrangement, sponsored, maintained or contributed to by the Company
or by any trade or business, whether or not incorporated (an "ERISA Affiliate"),
that together with the Company would be deemed a "single employer" within the
meaning of Section 4001 of the Employee Retirement Income Security Act of 1974,
as amended ("ERISA"), for the benefit of any employee or former employee or
director of the Company or any ERISA Affiliate employed in the United States
(the "Plans").

     (b) With respect to each Plan, the Company has heretofore delivered or made
available to Merger Company true and complete copies of each of the following
documents:

          (i) the Plan;

          (ii) the most recent annual report and actuarial report;

          (iii) the most recent Summary Plan Description required under ERISA
     with respect thereto;

          (iv) if the Plan is funded through a trust or third party funding
     vehicle, the trust or other funding agreement and the latest financial
     statements thereof; and

          (v) the most recent determination letter received from the Internal
     Revenue Service with respect to each Plan intended to qualify under Section
     401(a) of the Internal Revenue Code of 1986, as amended (the "Code") and
     each voluntary employee benefit association intended to qualify under
     Section 501(c)(9) of the Code.

     (c) No liability under Title IV of ERISA has been incurred by the Company
or any ERISA Affiliate that has not been satisfied in full, and no condition
exists that presents a material risk to the Company or any ERISA Affiliate of
incurring a liability under such Title, other than liability for contributions
due in the ordinary course and premiums due the Pension Benefit Guaranty
Corporation ("PBGC") (which contributions and premiums have been paid when due)
except for such liabilities that would not have a Material Adverse Effect.

     (d) No Plan that is an "employee benefit plan," as defined in Section 3(3)
of ERISA (an "ERISA Plan"), is a "multiemployer pension plan," as defined in
Section 3(37) of ERISA, nor is any ERISA Plan a plan described in Section
4063(a) of ERISA.

     (e) No ERISA Plan or any trust established thereunder has incurred any
"accumulated funding deficiency" (as defined in Section 302 of ERISA and Section
412 of the Code), whether or not waived, as of the last day of the most recent
fiscal year of each ERISA Plan ended prior to the Closing Date. Each ERISA Plan
intended to be "qualified" within the meaning of Section 401(a) of the Code has
been determined by the Internal Revenue Service to be so qualified (or timely
application has been made therefor); no event has occurred since the date of
such determination that would materially adversely affect such qualification;
and each trust maintained thereunder has been determined by the Internal Revenue
Service to be exempt from taxation under Section 501(a) of the Code. All
contributions or other payments required to have been made by Company and its
Subsidiaries to or under any Plan by applicable law or the terms of such Plan
have been timely and properly made. Each Plan has been operated and administered
in all material respects in accordance with its terms and applicable law,
including but not limited to ERISA and the Code except where a failure to so
operate or administer would not have a Material Adverse Effect. There are no
pending, or to the knowledge of the Company, threatened, material

                                      A-11
<PAGE>   129

claims by or on behalf of any Plan, by any employee or beneficiary covered under
any such Plan, or otherwise involving any such Plan (other than routine claims
for benefits).

     (f) Except as disclosed in Schedule 3.9(f) of the Disclosure Letter or in
connection with equity compensation or otherwise disclosed or referred to in
Section 3.9 (or in Section 3.9 of the Disclosure Letter), neither the execution
and delivery of this Agreement nor the consummation of the transactions
contemplated hereby will, without further action (i) result in any payment
becoming due to any current or former employee or director of Company and its
Subsidiaries, (ii) increase any benefits under any Plan, (iii) result in the
acceleration of the time of payment or vesting of any benefits, (iv) satisfy any
condition or requirement entitling any current or former employee or director of
Company and its Subsidiaries to additional rights or features with respect to
any benefits, or (v) result in any payment becoming due by the Company or any of
its Subsidiaries or the Merger Company that would be subject to Sections 162(m),
280G or 4999 of the Code.

     (g) Section 3.9(g) of the Disclosure Letter identifies each Employment
Agreement containing a provision for "Good Reason" or similar terms relating to
the potential termination of the employee's employment with the Company in
connection with the consummation of the Merger. Neither the Company nor its
Subsidiaries has taken any corporate action acknowledging that an individual
party to a Listed Employee Agreement will have, upon consummation of the Merger,
"Good Reason" or a similar right (as that term is defined in such Listed
Employee Agreement) to terminate his or her employment thereunder with the
Company.

     (h) With respect to each Plan that is not subject to United States law (a
"Foreign Plan"):

          (i) Except as disclosed in Schedule 3.9(h) of the Disclosure Letter,
     with respect to each Foreign Plan, any liability for accrued benefit
     obligations has been funded (through insurance or otherwise) or a book
     reserve account has been established (in each case sufficient to procure or
     provide for the accrued benefit obligations in accordance with GAAP), and
     each such account is reflected on the Balance Sheets except for such
     liability for accrued benefit obligations incurred in the ordinary course
     of business consistent with past practice since December 31, 1998 or
     otherwise disclosed in the Company SEC Documents; and

          (ii) each Foreign Plan required to be registered has been registered
     and has been maintained in good standing with applicable regulatory
     authorities.

     SECTION 3.10  Litigation; Compliance with Law.

     (a) Except as expressly identified in the Company SEC Documents or Section
3.10 of the Disclosure Letter and except for claims under Environmental Laws
(which are the subject of Section 3.15), (i) as of the date hereof, there is no
suit, claim, action, proceeding or investigation pending or, to the knowledge of
the Company, threatened, against the Company or any of its Subsidiaries which

whether or not covered by insurance, and (ii) there is no suit, claim, action,
proceeding or investigation pending or, to the knowledge of the Company,
threatened, against the Company or any of its Subsidiaries which would have a
Material Adverse Effect.

     (b) Except as expressly identified in the Company SEC Documents and except
for Environmental Laws (which are the subject of Section 3.15), the operations
of the Company and its Subsidiaries are not being conducted in violation of any

Governmental Entity, except where such violations would not have a Material
Adverse Effect.

     (c) The Company and its Subsidiaries hold all licenses, permits, variances
and approvals of Governmental Entities necessary for the lawful conduct of their
respective businesses as currently conducted except for licenses, permits,
variances or approvals under Environmental Laws (which are the subject of

     (d) Except as set forth in Schedule 3.10(d) of the Disclosure Letter, or as
set forth in the Balance Sheets, neither the Company nor any of its Subsidiaries
has, as of the date therein, any liabilities associated with the matters
contemplated by this Section 3.10 which would be required to be reflected or
reserved against in a consolidated balance sheet of the Company and its
Subsidiaries prepared in accordance with GAAP, except for such liabilities as
were incurred in the ordinary course of business or would not have a Material
Adverse Effect.

     SECTION 3.11  Intellectual Property. Section 3.11 of the Company Disclosure
Letter sets forth a list of all registered and pending applications for
Intellectual Property (as hereinafter defined) of the Company or its
Subsidiaries material to the Company taken as a whole. The Company and its

and other confidential or proprietary rights and information, inventions,
processes, formulae, as well as all goodwill symbolized by any of the foregoing
(collectively, "Intellectual Property") necessary in connection with the
business of the Company and its Subsidiaries as currently conducted, except
where the failure to possess such rights or licenses would not have a Material
Adverse Effect. Except as disclosed in Section 3.11 of the Disclosure Letter,
(i) the conduct, products or services of the business of the Company and its
Subsidiaries as currently conducted do not infringe upon any Intellectual
Property of any third party except where such infringement would not reasonably
be expected to create a liability in excess of $2,000,000 or otherwise would not
have a Material Adverse Effect, (ii) there are no claims or suits pending or for
which written notice has been provided or, to the knowledge of the Company,
threatened (A) alleging that the Company's or its Subsidiaries' conduct,
products or services infringe upon any Intellectual Property of any third party

liability in excess of $2,000,000 or otherwise have a Material Adverse Effect,
or (B) challenging the Company's or its Subsidiaries' ownership of, right to
use, or the validity or enforcement of any license or other agreement relating
to, the Company's and its Subsidiaries' Intellectual Property, and (ii) to the
knowledge of the Company, no Person is infringing upon any Intellectual Property
of the Company or its Subsidiaries except where such infringement would not have
a Material Adverse Effect. The execution and delivery of this Agreement and the
consummation of the transactions contemplated hereby will not result in the loss
of, or any encumbrance on, the rights of the Company or any Subsidiary with
respect to the Intellectual Property owned or used by them, except where such
loss or encumbrance would not reasonably be expected to create a liability in
excess of $2,000,000 or otherwise have a Material Adverse Effect. All
Intellectual Property necessary in connection with the business of the Company
and its Subsidiaries is valid, subsisting, enforceable and, where applicable,
has been properly maintained, except as would not have a Material Adverse
Effect.

     SECTION 5.2  Acquisition Proposals.

     (a) The Company agrees that, except as expressly contemplated by this
Agreement, neither it nor any of its Subsidiaries shall, and shall instruct
their respective officers or directors, investment bankers, attorneys,
accountants, financial advisors, agents or other representatives not to (i)
initiate, solicit, encourage or knowingly facilitate the making of any
Acquisition Proposal (as hereinafter defined) or (ii) except as permitted below,
engage in negotiations or discussions with, or furnish any non-public
information or data to, any third party relating to an Acquisition Proposal
(other than the transactions contemplated by this Agreement). Notwithstanding
anything to the contrary contained in this Agreement, until the receipt of the
Required Vote, and subject to the provisions of Section 5.2(b) and (c), the
Company and the Board (i) may participate in negotiations or discussions
(including, as a part thereof, making any counterproposal) with or furnish
information or data to any third party pursuant to a confidentiality agreement
on terms no less favorable to the Company as the Confidentiality Agreement (as
defined hereinafter), if either (A) the Board determines in good faith, after
receiving the advice of its financial advisors, that a third party has made a
Superior Proposal after the date hereof or an Acquisition Proposal that the
Board concludes would be reasonably likely to constitute a Superior Proposal
(and such Acquisition Proposal was not solicited by the Company or any affiliate
or agent of the Company at the explicit or implicit direction of the Company) or
(B) the Board determines in good faith, after consultation with independent
counsel, that the failure to participate in such negotiations or discussions or
to furnish such information or data would be reasonably likely to constitute a
breach of the Board's fiduciary duties under applicable law, (ii) shall be
permitted to (X) take and disclose to the holders of the Company Common Stock a
position with respect to the Merger or another Acquisition Proposal (including a
Superior Proposal), or amend or withdraw such position, if, based on the advice
of independent counsel, the Board determines that such action is required
pursuant to Rules 14d-9 and 14e-2 under the Exchange Act and (Y) make disclosure
to stockholders as the Board determines after consultation with independent
counsel is necessary to comply with the Board's fiduciary duties under
applicable law and (iii) shall be permitted to request from any Person making an
Acquisition Proposal such information as may be necessary for the Board to
inform itself as to the material terms of the Acquisition Proposal. Immediately
after the execution and delivery of this Agreement, the Company and its
Subsidiaries will, and will instruct their respective officers, directors,
employees, investment bankers, attorneys, accountants and other agents to, cease
and terminate any existing activities, discussions or negotiations with any
parties conducted heretofore with respect to any possible Acquisition Proposal.
The Company agrees that it will take the necessary steps to promptly inform its
officers, directors, investments bankers, attorneys, accountants, financial
advisors, agents or other representatives involved in the transactions
contemplated by this Agreement of the obligations undertaken in this Section
5.2(a).

     (b) In addition to the obligations of the Company set forth in paragraph
(a) above, the Company shall advise Merger Company orally and in writing by the
end of the next Business Day, but in no event more than 36 hours after its
receipt), of any written request for information or of any Acquisition Proposal
and the material terms and conditions of such request or Acquisition Proposal
and the identity of the person making any such request, or Acquisition Proposal
and any determination by the Board that an Acquisition Proposal is a Superior
Proposal. The Company will keep Merger Company reasonably informed as to the
status and material terms and conditions of any such request or Acquisition
Proposal.

     (c) If the Board is entitled to engage in negotiations or discussions with,
or furnish any information or data to, any third party on the terms contemplated
in Section 5.2(a), the Board may, prior to the Required Vote, (i) (in addition
to any other right that it may have to withdraw or modify its recommendation in
the exercise of its fiduciary duties) withdraw or modify, or propose publicly to

                                      A-25
<PAGE>   143

withdraw or modify, in a manner adverse to Merger Company, the approval or
recommendation by the Board of the Merger or this Agreement or the Charter
Amendment, (ii) approve or recommend, or propose publicly to approve or
recommend, any Acquisition Proposal or (iii) cause the Company to enter into any
letter of intent, agreement in principle, acquisition agreement or other similar
agreement related to any Acquisition Proposal. The Board may only take the
actions described in clauses (ii) and (iii) of this subparagraph (c) if the
Board determines in good faith, after receiving the advice of its financial
advisors, that it has received a Superior Proposal and this Agreement has
terminated in accordance with the procedures contemplated in Section 7.1(c),
including following the expiration of the five Business Day period contemplated
therein and the Company having paid any required Termination Fee and Expenses as
contemplated therein.

     (d) For purposes of this Agreement, "Acquisition Proposal" shall mean any
bona fide proposal for the (i) direct or indirect acquisition or purchase of a
business or assets that constitutes 15% or more of the net revenues, net income
or the assets (based on the fair market value thereof) of the Company and its
Subsidiaries, taken as a whole, (ii) direct or indirect acquisition or purchase
of 15% or more of any class of equity securities or capital stock of the Company
or any of its Subsidiaries whose business constitutes 15% or more of the net
revenues, net income or assets of the Company and its Subsidiaries, taken as a
whole, or (iii) merger, consolidation, restructuring, transfer of assets or
other business combination, sale of shares of capital stock, tender offer,
exchange offer, recapitalization, stock repurchase program or other similar
transaction that if consummated would result in any person or persons
beneficially owning 15% or more of any class of equity securities of the Company
or any of its Subsidiaries whose business constitutes 15% or more of the net
revenues, net income or assets of the Company and its Subsidiaries, taken as a
whole, other than the transactions contemplated by this Agreement. The term
"Superior Proposal" shall mean any bona fide proposal, which was not solicited
by the Company or any affiliate or agent of the Company at the explicit or
implicit direction of the Company, to enter into an Acquisition Proposal made by
a third party on terms and conditions which the Board determines in its good
faith judgment, after receiving the advice of its financial advisors, to be more
favorable to the holders of the Company Common Stock from a financial point of
view than the transactions contemplated hereby (taking account of all of the
terms thereof, including price, likelihood of financing being available and
expected timing of consummation).

     SECTION 5.3  Access to Information. From the date of this Agreement until
the Effective Time, the Company shall and shall cause each of its Subsidiaries
to afford to Merger Company and its officers, employees, accountants, counsel
and its authorized representatives (including environmental consultants to the
extent provided in Section 5.8) reasonable access during normal business hours
upon reasonable prior notice to all of its books, records, assets, properties
(provided that environmental testing may only be performed by or on behalf of
Merger Company to the extent set forth in Section 5.8) and operations and,
during such period, the Company shall furnish promptly to Merger Company (i) a
copy of each report, letter, registration statement and other document filed or
received by it during such period pursuant to the requirements of the Exchange
Act, (ii) a copy of all correspondence, including pleadings, relating to the
obtaining of the order contemplated in Section 6.1(f) and (iii) such other
information used in the operation of its business as Merger Company may
reasonably request and the provision of which is not inconsistent with
applicable laws and would not breach any agreements. Merger Company and its
authorized representatives will conduct all such inspections in a manner which
will minimize any disruptions of the business and operations of the Company and
its Subsidiaries. Until the Effective Time, Merger Company will hold any such
information in accordance with the provisions of the confidentiality agreement
between the Company and Bear, Stearns & Co., Inc., dated March 1, 2000 as if
Merger Company were a party thereto (the "Confidentiality Agreement"), and will
cause such information to be so held by their Representatives (as defined in the
Confidentiality Agreement). Upon a termination of this Agreement pursuant to
Section 7.1, Merger Company and its Representatives shall return (and hold
confidential) all information provided pursuant to this Section 5.3 and all
other Evaluation Material (as defined in the Confidentiality Agreement) pursuant
to the procedures set forth in the Confidentiality Agreement.

     SECTION 5.4  Further Action; Commercially Reasonable Efforts.

     (a) Upon the terms and subject to the conditions herein provided, each of
the parties hereto agrees to use its commercially reasonable efforts to take, or
cause to be taken, all action and to do, or cause to be done, all things
necessary, proper or advisable under applicable laws and regulations to
consummate and make effective the transactions contemplated by this Agreement,
including using commercially reasonable efforts to satisfy the conditions
precedent to the obligations of any of the parties hereto, to obtain all
necessary authorizations, consents and approvals, and to effect all necessary
registrations and filings. Each of the parties hereto will furnish to the other
parties such necessary information and reasonable assistance as such other
parties may reasonably request in connection with the foregoing and will provide
the other parties with copies of all filings made by such party with any
Governmental Entity or any other information supplied by such party to a
Governmental Entity in connection with this Agreement and the transactions
contemplated hereby.

     (b) The Company agrees to, and to cause its Subsidiaries and its and their
respective officers, employees, advisors and accountants to, reasonably
cooperate with Merger Company in connection with the arrangement of any
financing to be consummated prior to or contemporaneously with the Closing in
respect of the transactions contemplated by this Agreement, including
participation in meetings, due diligence sessions, road shows, the preparation
of offering memoranda, private placement memoranda, prospectuses and similar
documents and comfort letters of accountants, as may be reasonably requested by
Merger Company. In conjunction with the obtaining of any such financing, the
Company agrees, at the reasonable request of Merger Company, to call for
prepayment or redemption, or to prepay or redeem, or to attempt to renegotiate
the terms of, any then existing indebtedness for borrowed money of the Company;
provided, however, that no such prepayment or redemption or call for prepayment
or redemption or renegotiated terms shall actually be made or become effective
(nor shall the Company be required to incur any liability in respect of any such
prepayment or redemption or call therefor or renegotiation thereof) prior to the
Effective Time. Merger Company will promptly inform the Company of all material
developments relating to arranging such financing.

     (c) Merger Company and the Company shall use their respective commercially
reasonable efforts to resolve such objections, if any, as may be asserted with
respect to the transactions contemplated hereby under the laws, rules,
guidelines or regulations of any Governmental Entity. Without limiting the
foregoing, the Company and Merger Company shall, as soon as practicable, file
Notification and Report Forms under the HSR Act (as defined below) with the
Federal Trade Commission (the "FTC") and the Antitrust Division of the
Department of Justice (the "Antitrust Division") and shall use commercially
reasonable efforts to respond as promptly as practicable to all inquiries
received from the FTC or the Antitrust Division for additional information or
documentation. "Competition Laws" means statutes, rules, regulations, orders,
decrees, administrative and judicial doctrines, and other laws that are designed
or intended to prohibit, restrict or regulate actions having the purpose or
effect of monopolization, lessening of competition or restraint of trade and
includes the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended
(the "HSR Act") and, to the extent applicable, equivalent laws of the European
Union or the Member States thereof.

     (d) The Company shall cooperate with Merger Company, and use its
commercially reasonable efforts to take all action necessary (including agreeing
to amend this Agreement and/or restructure the transactions contemplated hereby
prior to the Special Meeting), to cause the Surviving Corporation to be entitled
to recapitalization accounting treatment for the transactions contemplated
hereby for GAAP and SEC financial reporting purposes, provided that the Board
determines that any such action would not reasonably be expected to affect
adversely the Company or any of its stockholders.

     (e) The Company shall cooperate with Merger Company in connection with any
decision by Merger Company to order, at the sole expense of Merger Company, any
title insurance commitment or commitments with respect to each parcel of Owned
Property. The Company shall cooperate with Merger Company in the event that
Merger Company elects to purchase, at the sole expense of Merger Company,

                                      A-27
<PAGE>   145

title insurance and/or order, at the sole expense of Merger Company, surveys
with respect to each parcel of Owned Property.

     (f) Finance Company will use its commercially reasonable efforts to obtain
as promptly as practicable the Financing required to be obtained to consummate
the transactions contemplated hereby, as described in Section 4.6, provided that
Finance Company shall not be obligated to seek a waiver of the conditions to
such Financing. Neither Finance Company nor Merger Company will intentionally
take any action that would be reasonably likely to result in the failure of the
consummation of the Financing.

     (g) In case at any time after the Effective Time any further action is
necessary or desirable to carry out the purposes of this Agreement, the proper
officers and/or directors of the Surviving Corporation shall take or cause to be
taken all such necessary action.

     (h) Each of the parties shall use commercially reasonable efforts to
prevent the entry of, and to cause to be discharged or vacated, any order or
injunction of a Governmental Entity precluding, restraining, enjoining or
prohibiting consummation of the Merger.

     SECTION 5.5  Employee Benefits.

     (a) Surviving Corporation hereby agrees to honor, and to make required
payments when due under, all contracts, agreements, arrangements, policies,
plans and commitments of the Company and its Subsidiaries in effect as of the
date hereof which are applicable with respect to any employee, officer, director
or executive or former employee, officer, director or executive of the Company
or any Subsidiary thereof, including the Benefit Plans in existence as of the
date hereof. Nothing herein shall be construed to prohibit the Surviving
Corporation from amending or terminating such contracts, agreements,
arrangements, policies, plans and commitments in accordance with the terms
thereof and with applicable law.

     (b) Surviving Corporation hereby agrees to assume, each employment,
retention, consulting or severance agreement or arrangement that was entered
into by and between the Company and any employee, officer, director or executive
or former employee, officer, director or executive of the Company or any
Subsidiary thereof and that is in effect as of the date hereof and has been
delivered to Merger Company as of the date hereof.

     (c) Surviving Corporation hereby agrees that after the Effective Time, it
shall continue to maintain until the end of year 2001 the core benefits
identified on Schedule 5.5 of the Disclosure Letter for the benefit of employees
and former employees of the Company and its Subsidiaries which in the aggregate
provide benefits that are no materially less favorable taken as a whole (on a
value or cost basis) than those provided to them under the Benefit Plans on the
date hereof. In addition, Surviving Corporation hereby agrees that for a period
of eighteen months immediately following the Effective Time, it shall, or shall
cause the Surviving Corporation to, continue to maintain the Company Separation
Policy as in effect on the date hereof, without any amendment thereto which is
adverse to the participants therein.

     (d) For purposes of all employee benefit plans, programs and arrangements
maintained by or contributed to by Surviving Corporation and its Subsidiaries,
Surviving Corporation shall cause each such plan, program or arrangement to
treat the prior service with the Company and its affiliates of each person who
is an employee or former employee of the Company or its Subsidiaries immediately
prior to the Effective Time (a "Company Employee") (to the same extent such
service is recognized under analogous plans, programs or arrangements of the
Company or its affiliates prior to the Effective Time) as service rendered to
Surviving Corporation, for purposes of eligibility to participate and vesting;
provided, however, that any benefits provided by Surviving Corporation under any
(i) ERISA Plan, (ii) nonqualified employee benefit or deferred compensation
plans, stock option, bonus or incentive plans or (iii) other employee benefit or
fringe benefit programs, that may be in effect generally for employees of
Surviving Corporation or its Subsidiaries from time to time, shall be reduced by
benefits in respect of the same years of service under analogous plans, programs
and arrangements maintained by or contributed to by the Company, the Surviving
Corporation or their Subsidiaries. Surviving Corporation shall (x) waive all
limitations as to preexisting conditions exclusions and waiting periods with
respect to participation and coverage requirements applicable to the Company
Employees under any welfare benefit plans that such

                                      A-28
<PAGE>   146

Company Employees may be eligible to participate in after the Effective Time,
other than limitations or waiting periods that are already in effect with
respect to such employees and that have not been satisfied as of the Effective
Time under any welfare benefit plan maintained for the Company Employees
immediately prior to the Effective Time and (y) provide each Company Employee
with credit for any co-payments and deductibles paid prior to the Effective Time
in satisfying any applicable deductible or out-of-pocket requirements under any
welfare plans that such employees are eligible to participate in after the
Effective Time.

     (e) Surviving Corporation shall pay (no later than the February 15th
following the Year for which the payment is due) to each individual who was a
participant in any of the Company's annual incentive compensation plans (each, a
"Bonus Plan") immediately prior to the Effective Time, a lump sum cash payment
equal to the product of (i) the bonus which such participant would have earned
in respect of the year (the "Year") in which the Effective Time occurs, based
upon the actual performance in such Year prior to the Effective Time, compared
to the target performance levels for the period in such Year prior to the
Effective Time and (ii) a fraction, the numerator of which is the number of days
in such Year prior to the Effective Time and the denominator of which is 365;
provided that such individual will only be entitled to such payment if still
employed at the end of such Year except for individuals previously identified to
Merger Company in writing to whom such requirement shall be inapplicable. Merger
Company may permit each member of Management as it shall designate to elect,
prior to the Effective Time, to invest such deferred bonus amount in shares of
Surviving Corporation Common Stock and Surviving Corporation Junior Preferred
Stock. In the event of such election, the shares will be issued no later than
the February 15th following the Year for which payment is due to those
individuals employed at the end of such Year. The number of shares of Surviving
Corporation Common Stock and Surviving Corporation Junior Preferred Stock to be
issued will be determined by dividing the amount that would otherwise be payable
as a bonus that is elected to be converted by $15.625 and multiplying such
amount by the TM Merger Consideration. Notwithstanding anything in any employee
agreement to the contrary, the payment under this Section 5.5(e) shall offset
any payment under such employee agreement with respect to the prorated bonus
which may be payable under such employee agreement with respect to the year in
which the Effective Time occurs. Surviving Corporation shall implement a
replacement annual incentive compensation plan similar to the existing plan
except with respect to the targets thereunder for the remainder of the year in
which the Effective Time occurs.

     SECTION 5.6  Stockholders Meeting; Proxy Statement.

     (a) The Company shall, in accordance with applicable law and the Restated
Certificate of Incorporation and the By-laws of the Company duly call, give
notice of, convene and hold a meeting of its stockholders (the "Special

purpose of considering and taking action upon this Agreement, the Charter
Amendment and such other matters as may be appropriate at the Special Meeting.

     (b) As soon as reasonably practicable following the date of this Agreement,
the Company shall prepare and file with the SEC, and Merger Company and Finance
Company shall cooperate with the Company in such preparation and filing, an S-4

other statement or schedule relating to this Agreement and the transactions
contemplated hereby and use their respective commercially reasonable efforts to
furnish the information required to be included by the SEC in the S-4, the Proxy

consultation with Merger Company, the Company shall respond promptly to any
comments made by the SEC with respect to the S-4 or the preliminary proxy
statement and cause a definitive proxy statement (the "Proxy Statement") to be
mailed to its stockholders and the parties shall respond promptly to any
comments with respect to any other statement or schedule filed by them. No
filing of, or amendment or supplement to, the S-4, or the Proxy Statement or any
other statement or schedule will be made by the Company without providing Merger
Company a reasonable opportunity to review and comment thereon, and no filing of
any statement or schedule will be made by Merger Company or Finance Company
without providing the Company a reasonable opportunity to review and comment
thereon. If at any time after the date the S-4 is declared effective by the SEC
or otherwise

                                      A-29
<PAGE>   147

becomes effective and prior to the Special Meeting any information relating to
the Company, Merger Company or Finance Company, or any of their respective
affiliates, officers or directors, should be discovered by the Company, Merger
Company or Finance Company which is required to be set forth in an amendment or
supplement to the S-4, the Proxy Statement or any other statement or schedule,
so that none of the S-4, the Proxy Statement and any such statement or schedule
will include any untrue statement of a material fact or omit to state any
material fact necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading, the party which
discovers such information shall promptly notify the other party hereto and an
appropriate amendment or supplement describing such information shall be
promptly filed with the SEC and, to the extent required by law, disseminated to
the stockholders of the Company. Subject to the fiduciary obligations of the
Board and applicable law, the Company shall include in the Proxy Statement the
recommendation of the Board that stockholders of the Company adopt this
Agreement.

     (c) Merger Company and Finance Company agree that (i) they will provide the
Company with all information concerning Merger Company and Finance Company and
their affiliates necessary or appropriate to be included in the Proxy Statement
and (ii) at the Special Meeting or any postponement or adjournment thereof (or
at any other meeting at which the Merger or this Agreement are considered by
stockholders), they will vote, or cause to be voted, all of the Shares then
owned by them, or any of their Subsidiaries and affiliates, if any, in favor of
the approval and adoption of this Agreement.

     SECTION 5.7  Directors' and Officers' Insurance and Indemnification.

     (a) The certificate of incorporation and by-laws of the Surviving
Corporation shall contain the provisions with respect to indemnification set
forth in Article VIII of the Restated Certificate of Incorporation and Article
IV of the Company's By-laws on the date of this Agreement and such additional
provisions relating thereto as are described in Exhibit B and Exhibit C attached
hereto and shall provide for indemnification to the fullest extent permitted by
and in accordance with the DGCL, which provisions shall not be amended, repealed
or otherwise modified for a period of six years after the Effective Time (or, in
the case of matters occurring prior to the Effective Time which have not been
resolved prior to the sixth anniversary of the Effective Time, until such
matters are finally resolved) in any manner that would adversely affect the
rights thereunder of individuals who at any time prior to the Effective Time
were directors or officers of the Company in respect of actions or omissions
occurring at or prior to the Effective Time (including the transactions
contemplated by this Agreement).

     (b) The Surviving Corporation and its Subsidiaries shall indemnify at all
times after the Effective Time each person who is now, or has been at any time
prior to the date hereof, an employee, agent, director or officer of the Company
or of any of the Company's Subsidiaries (individually an "Indemnified Party" and
collectively the "Indemnified Parties"), to the fullest extent permitted by
applicable law, with respect to any claim, liability, loss, damage, cost or
expense, whenever asserted or claimed ("Indemnified Liability"), based in whole
or in part on, or arising in whole or in part out of, any matter existing or
occurring at or prior to the Effective Time. The Surviving Corporation shall
maintain in effect for not less than six years after the Effective Time policies
of directors' and officers' liability insurance equivalent in all material
respects to those maintained by or on behalf of the Company and its Subsidiaries
on the date hereof (and having at least the same coverage and containing terms
and conditions which are no less advantageous to the persons currently covered
by such policies as insured) with respect to matters existing or occurring at or
prior to the Effective Time; provided, however, that if the aggregate annual
premiums for such insurance at any time during such period shall exceed 200% of
the per annum rate of premium currently paid by the Company and its Subsidiaries
for such insurance on the date of this Agreement, then Surviving Corporation
shall provide the maximum coverage that shall then be available at an annual
premium equal to 200% of such rate. Without limiting the foregoing, in the event
any Indemnified Party becomes involved in any capacity in any action, proceeding
or investigation based in whole or in part on, or arising in whole or in part
out of, any matter, including the transactions contemplated hereby, existing or
occurring at or prior to the Effective Time, then to the extent permitted by
law, Surviving Corporation shall periodically advance to such Indemnified Party
its legal and other expenses (including the cost of any investigation and
preparation incurred in connection therewith), subject to the provision by such

                                      A-30

Indemnified Party of an undertaking to reimburse the amounts so advanced in the
event of a final determination by a court of competent jurisdiction that such
Indemnified Party is not entitled thereto. Promptly after receipt by an
Indemnified Party of notice of the assertion (an "Assertion") of any claim or
the commencement of any action against him in respect to which indemnity or
reimbursement may be sought against the Company, the Surviving Corporation or a
subsidiary of the Company or the Surviving Corporation ("Indemnitors")
hereunder, such Indemnified Party shall notify any Indemnitor in writing of the
Assertion, but the failure to so notify any Indemnitor shall not relieve any
Indemnitor of any liability it may have to such Indemnified Party hereunder
except to the extent that such failure shall have materially and irreversibly
prejudiced Indemnitor in defending against such Assertion. Indemnitors shall be
entitled to participate in and, to the extent Indemnitors elect by written
notice to such Indemnified Party within 30 days after receipt by any Indemnitor
of notice of such Assertion, to assume the defense of such Assertion, at their
own expense, with counsel chosen by Indemnitors and reasonably satisfactory to
such Indemnified Party. Notwithstanding that Indemnitors shall have elected by
such written notice to assume the defense of any Assertion, such Indemnified
Party shall have the right to participate in the investigation and defense
thereof, with separate counsel chosen by such Indemnified Party, but in such
event the fees and expenses of such counsel shall be paid by such Indemnified
Party unless such separate counsel is required due to a conflict of interest, in
which case the Indemnitors shall be responsible for the fees and expenses of one
separate counsel. No Indemnified Party shall settle any Assertion without the
prior written consent of Surviving Corporation, nor shall Surviving Corporation
settle any Assertion without either (i) the written consent of all Indemnified
Parties against whom such Assertion was made, or (ii) obtaining an unconditional
general release from the party making the Assertion for all Indemnified Parties
as a condition of such settlement. The provisions of this Section 5.7 are
intended for the benefit of, and shall be enforceable by, the respective
Indemnified Parties.

     SECTION 5.8  Environmental Assessments.

     In the event the Company or Merger Company receives information after the
date hereof as a result of which it concludes in good faith that a site or sites
owned or operated by the Company has associated with it Environmental Costs and
Liabilities that would have a Material Adverse Effect, Merger Company shall have
the right to arrange at its sole cost and expense, upon reasonable notice to the
Company, for an independent environmental professional, possessing reasonable
levels of insurance and skills, to conduct tests at such sites; provided, that
such testing shall be conducted upon reasonable notice to the Company, in such a
manner as to minimize disruption to the Company's operations, and in accordance
with a sampling procedure approved in advance by the Company. Merger Company
will, at the Company's option, provide the Company with split samples from such
testing and copies of any reports prepared in connection therewith.

     SECTION 5.9  Environmental Transfer Laws. Prior to the Closing, the Company
shall use its commercially reasonable efforts to ensure compliance with all
Environmental Property Transfer Laws, including the New Jersey Industrial Site
Recovery Act.

     SECTION 5.10  Solvency Letter.

     (a) Merger Company shall at its sole cost and expense engage, and use
commercially reasonable efforts to cause, a reputable appraisal firm selected by
Merger Company and reasonably satisfactory to the Company (the "Appraiser") to
deliver to the Company and the Board at the Closing a letter addressed to Merger
Company, the Company and the Board (the "Solvency Letter") to the effect that,
immediately after the Effective Time and after giving effect to the Merger, the
Financing and the other transactions contemplated in connection therewith (and
any changes in the Surviving Corporation's assets and liabilities as a result
thereof), the Surviving Corporation: (i) will be solvent (i.e., in that both the
fair value of its assets will not be less than the sum of its debts and that the
present fair saleable value of its assets will not be less than the amount
required to pay its probable liability on its debts as they become absolute and
matured); (ii) will not have unreasonably small capital with which to engage in
its business; and (iii) will not have incurred and does not plan to incur debts
beyond its ability to pay as they become absolute and matured.

                                      A-31
<PAGE>   149

     Merger Company will request the Appraiser to deliver a form of the Solvency
Letter as promptly as practicable but in no event later than five Business Days
prior to the Closing Date. The parties agree to cooperate with the Appraiser in
connection with the preparation of the Solvency Letter, including, providing the
Appraiser with any information reasonably available to them necessary for the
Appraiser's preparation of such letter.

     SECTION 5.11  Indemnity. The Company, if prior to the Effective Time, and
the Surviving Corporation, at all times after the Effective Time (each, a
"Merger Party Indemnitor"), shall indemnify Merger Company, Finance Company,
their respective affiliates and each person who is now, or has been at any time
prior to the date hereof, an employee, agent, director or officer of Merger
Company or Finance Company, or of any of Merger Company's or Finance Company's
Subsidiaries and affiliates (including Bear Stearns Merchant Fund Corp., Hicks,
Muse, Tate & Furst Incorporated and their respective affiliates) (individually
an "Indemnified Merger Party" and collectively the "Indemnified Merger
Parties"), to the fullest extent permitted by applicable law, with respect to
any claim, liability, loss, damage, cost or expense, asserted against, or
incurred by, an Indemnified Merger Party which is primarily based on an
allegation that an Indemnified Merger Party has induced or acted in concert with
the Company or any of its directors to act contrary to or in violation of any
contract, duty or applicable law, to which the Company and the directors are
subject, to the extent such allegation relates to the negotiation, execution or
delivery of this Agreement or the Trust Voting Agreement by the parties hereto
and thereto or the performance of the obligations of the parties hereunder or
thereunder (an "Indemnified Litigation Matter"). Promptly after receipt by an
Indemnified Merger Party of notice of the assertion of any claim or the
commencement of any action against such Indemnified Merger Party in respect to
which indemnity or reimbursement may be sought against under this Section 5.11
(an "Assertion Against HB"), such Indemnified Merger Party shall notify the
Merger party Indemnitor in writing of the Assertion Against HB, but the failure
to so notify shall not relieve of any liability it may have to such Indemnified
Merger Party hereunder except to the extent that such failure shall have
actually prejudiced in defending against such Assertion Against HB. In the event
that following receipt of notice from the Indemnified Merger Party, a Merger
Party Indemnitor notifies the Indemnified Merger Party that it desires to defend
the Indemnified Merger Party against such Assertion Against HB, such Merger
Party Indemnitor shall have the right to defend the Indemnified Merger Party by
appropriate proceedings and shall have the sole power to direct and control such
defense. If any Indemnified Merger Party desires to participate in any such
defense it may do so at its sole cost and expense, provided, however, that if
the defendants in any such action shall include the Company and/or its officers
or directors as well as an Indemnified Merger Party and such Indemnified Merger
Party shall have received the advice of counsel that there exist defenses to
such Indemnified Merger Party that are different from or additional to those
available to the Company and/or such officers or directors, the Indemnified
Merger Parties shall have the right to select one separate counsel (and one
local counsel in such jurisdictions as are necessary) reasonably acceptable to
the Company to participate in the defense of such action on its behalf, at the
expense of the Company. If the Indemnified Merger Parties retain such counsel,
then to the extent permitted by law, the Merger Party Indemnitor shall
periodically advance to such Indemnified Merger Parties their reasonable legal
and other out-of-pocket expenses relating to the Indemnified Litigation Matter
(including the reasonable cost of any investigation and preparation incurred in
connection therewith). No Indemnified Merger Party shall settle any Assertion
Against HB without the prior written consent of the Merger Party Indemnitor, nor
shall the Merger Party Indemnitor settle any Assertion Against HB without either
(i) the written consent of all Indemnified Merger Parties against whom such
Assertion Against HB was made, or (ii) obtaining an unconditional general
release from the party making the Assertion Against HB for all Indemnified
Merger Parties as a condition of such settlement. The provisions of this 5.11
are intended for the benefit of, and shall be enforceable by, the respective
Indemnified Merger Parties.

     SECTION 5.12  Listing for Surviving Corporation Preferred Stock. Merger
Company agrees to use its commercially reasonable efforts to have the Surviving
Corporation Preferred Stock eligible for trading on the Nasdaq National Market.
If the Surviving Corporation Preferred Stock is not eligible for trading on the
Nasdaq National Market as of the Closing Date, Merger Company will use its
commercially

reasonable efforts to arrange for an established securities dealer or dealers to
make a market in the Surviving Corporation Preferred Stock.

     SECTION 5.13  Stockholders Agreement. On or prior to the Closing Date, the
Company will execute and deliver, and Merger Company shall cause the members
thereof to execute and deliver, to the Trust the Stockholders Agreement among
the Company, the members of the Merger Company, Management and the Trust, in the
form attached hereto as Exhibit G.

     SECTION 5.14  Exchange of Certain Company Common Stock. Immediately prior
to the Closing (and after the Required Vote), the Company shall issue the Class
TM Preferred Stock to the Trust and Management, in accordance with the terms of
the exchange agreement among the Company, the Trust and Management regarding the
exchange of certain Company Common Stock to Class TM Preferred Stock, in the
form attached hereto as Exhibit H (the "TM Exchange Agreement").

     SECTION 5.15  Charter Amendment. On or prior to the Closing Date, the
Company shall file with the Secretary of State a certificate of amendment to the
Restated Certificate of Incorporation giving effect to the Charter Amendment.

     under the Trust Merger Agreements and discharging fully the Trustees of the

     impair the consummation of the transactions contemplated by this Agreement,

the Company may rely on the failure of any condition set forth in Section 6.2

                                  TERMINATION

     SECTION 7.1  Termination. Notwithstanding anything herein to the contrary,
this Agreement may be terminated and the Merger may be abandoned at any time
prior to the Effective Time, whether before or after stockholder adoption of
this Agreement, except for clause (c) below which cannot be effectuated after
the adoption of this Agreement by the stockholders of the Company by the
Required Vote:

          (a) By the mutual consent of the Members of Merger Company and the
     Board.

          (b) By either the Company or Merger Company if:

             (i) the Merger shall not have been consummated on or prior to
        November 30, 2000; provided, however, that such date shall automatically
        be extended to December 28, 2000 if the Special Meeting shall not have
        been held on or prior to November 1, 2000; and provided further that if
        the Special Meeting shall not have been held on or prior to December 1,
        2000 such date shall automatically be extended to the later of December
        28, 2000 or that date which is 15 Business Days after the Special
        Meeting is held but in no event shall such date extend beyond January
        31, 2001 or such other date, if any, as Merger Company and the Company
        shall agree in writing (provided that the right to terminate this
        Agreement under this Section 7.1(b)(i) shall not be available to a party
        whose failure to fulfill in any material respect any obligation under
        this Agreement has been the cause of or resulted in the failure of the
        Effective Time to occur on or before such date); or

             (ii) the stockholders of the Company fail to adopt this Agreement
        by the Required Vote or fail to approve the Charter Amendment at the
        Special Meeting (including any postponement or adjournment thereof); or

             (iii) any Governmental Entity shall have issued a statute, order,
        decree or regulation or taken any other action (which statute, order,
        decree, regulation or other action the parties hereto shall have used
        their commercially reasonable efforts to lift), in each case permanently
        restraining, enjoining or otherwise prohibiting consummation of the
        Merger or making the Merger illegal and such statute, order, decree,
        regulation or other action shall have become final and non-appealable;
        or

             (iv) the other party is in material breach of its representations
        or warranties or fails to perform in any material respect its covenants
        or other agreements hereunder to the extent required to have been
        performed at such time, which breach or failure to perform (A) would
        give rise to the failure of a condition set forth in Section 6.2 in the
        case of such a breach or failure to perform on the part of the Merger
        Company or Section 6.3 in the case of such a breach or failure to
        perform on the part of Company and (B) is incapable of being cured by
        the party so breaching or failing to perform prior to November 30, 2000
        (or such later date as may be applicable as set forth in Section
        7.1(b)(i)) or, if capable of being cured by such date, is not cured
        within 30 days after the terminating party gives written notice of such
        breach to the other party; or

             (v) the Trust Voting Agreement is terminated pursuant to Section
        5(b) or Section 5(c) thereof provided that if the Trust Voting Agreement
        terminates pursuant to Section 5(b)(iii) thereof, the Company may not
        effect such termination unless contemporaneously therewith the Company
        pays or causes to be paid to Merger Company, or its designee, in
        immediately available funds the Termination Fee and any Expenses
        required to be paid pursuant to Section 8.1.

          (c) By the Company if (i) the Board authorizes the Company, subject to
     complying with the terms of this Agreement, to enter into a binding written
     agreement with respect to a transaction that constitutes a Superior
     Proposal and the Company has notified Merger Company in writing that it
     intends to enter into such an agreement and terminate this Agreement
     pursuant to this clause (c), attaching the most current version of such
     agreement to such notice, and (ii) during the five Business

                                      A-36
<PAGE>   154

     Day period after the Company's notice, the Company shall have negotiated
     with Merger Company regarding the terms and conditions of a revised
     proposal by Merger Company and if the Board of Directors of the Company
     shall have concluded, after considering any revised proposal made by Merger
     Company during such period that any Superior Proposal giving rise to the
     Company's notice, as then revised, continues to be a Superior Proposal. The

     Merger Company promptly if the Board determines not to enter into a binding
     agreement with respect to the Superior Proposal as to which notification

     agreement for a Superior Proposal, (ii) the Board shall have withdrawn or

     of such Acquisition Proposal as required by Section 5.2 or (z) the
     commencement of negotiations with such third party or (iv) the Special

     Governmental Entity from holding the Special Meeting.

     SECTION 7.2  Effect of Termination. In the event of the termination of this
Agreement as provided in Section 7.1, written notice thereof shall forthwith be
given to the other party specifying the provision hereof pursuant to which such
termination is made, and this Agreement shall forthwith become null and void

event of such termination, there shall be no liability on the part of Merger
Company or the Company except as set forth in Section 8.1 hereof, except with
respect to the requirement to comply with the Confidentiality Agreement and

                                  ARTICLE VIII

                                 MISCELLANEOUS

     SECTION 8.1  Fees and Expenses. Whether or not the Merger is consummated,
all costs and expenses incurred in connection with this Agreement and the
transactions contemplated hereby shall be paid by the party incurring such costs
or expenses, except as provided in Sections 5.7 and 5.11.

     (a) In the event that

          (i) this Agreement is terminated by the Company pursuant to Section
     7.1(c), or by the Company pursuant to Section 7.1(b)(v) due to the Trust
     Voting Agreement being terminated pursuant to Section 5(b)(i) or 5(b)(iii)
     thereof, or

          (ii) this Agreement is terminated by Merger Company pursuant to
     Section 7.1(d)(i) or Section 7.1(d)(ii) or by Merger Company pursuant to
     Section 7.1(b)(v) due to the Trust Voting Agreement being terminated

                                      A-37
<PAGE>   155

     then in each such case the Company shall pay, or cause to be paid,

          A. to Merger Company or its designee a fee (the "Termination Fee") of
     $53,000,000. Acceptance of payment of the Termination Fee by Merger Company
     shall constitute conclusive evidence that this Agreement has been validly
     terminated, and upon such payment, each of the Company, Merger Company and
     Finance Company shall be fully released and discharged from any liability
     under this Agreement; and

          B. to Merger Company and Finance Company as reimbursement, the amount
     of their documented out-of-pocket fees and expenses including commitment
     and other fees and expenses contemplated by the Commitment Letters and
     those fees and expenses for environmental testing, reasonably incurred
     thereby in connection with this Agreement and the transactions contemplated
     hereby (including those which may be incurred in connection with enforcing
     the terms of this Section 8.1), provided that in no event shall such
     expense reimbursement exceed in the aggregate $12,500,000 (the "Expenses").

     (b) In the event that

          (i) this Agreement is terminated by Merger Company pursuant to Section
     7.1(d)(iii) or 7.1(d)(iv) or by the Company or Merger Company pursuant to
     Section 7.1(b)(v) due to the Trust Voting Agreement being terminated
     pursuant to Section 5(b)(ii) or 5(c)(i) thereof or by Merger Company
     pursuant to Section 7.1(b)(iv) as a result of a willful breach of a
     representation or a willful breach of a covenant, or

          (ii) this Agreement is terminated pursuant to Section 7.1(b)(ii):

     then in each such case the Company shall pay, or cause to be paid,

          A. to Merger Company or its designee the Expenses; and

          B. if prior to the first anniversary of such termination the Company
     enters into a definitive agreement with respect to, or consummates, an
     Acquisition Proposal, the Termination Fee; provided, however, that if this
     Agreement is terminated as a result of the Trust Voting Agreement being
     terminated pursuant to Section 5(b)(ii) or 5(c)(i) thereof, then such
     Termination Fee shall only be required to be paid to Merger Company if
     (prior to such first anniversary) the Company enters into definitive
     documentation or consummates an Acquisition Proposal with (i) a Person that
     made an Acquisition Proposal after the date of the Confidentiality
     Agreement and prior to the time at which the Court entered its decision
     with respect to the Court Approval or (ii) any other Person if the
     consideration to be paid to the holders of the capital stock of the Company
     by such other Person is of equal or greater value than the consideration to
     be paid to such holders under this Agreement.

     (c) In the event that this Agreement is terminated by Merger Company
pursuant to Section 7.1(b)(iv) other than as a result of a willful breach of a
covenant, the Company shall pay or cause to be paid the Expenses to Merger
Company or its designee.

     (d) The Company shall pay the Termination Fee to Merger Company or its
designee concurrently with or prior to a termination referred to in clause
8.1(a)(i) above. The Company shall pay the Termination Fee to Merger Company or
its designee within 24 hours of a termination referred to clause 8.1(a)(ii)
above. The Company shall pay the Termination Fee to Merger Company or its
designee promptly (and in any event within two Business Days) after the first to
occur of the execution of an agreement relating to an Acquisition Proposal or
the consummation of an agreement relating to an Acquisition Proposal referred to
in clauses 8.1(b)(i) and 8.1(b)(ii) above.

     (e) With respect to the Termination Fee required to be paid on or prior to
the termination of the Agreement, the Company shall reimburse the Expenses to
Merger Company on the later of (i) the day that is two Business Days after such
termination and (ii) the day that is two Business Days after the delivery by
Merger Company to the Company of documents reflecting expenses incurred.

     (f) In the event that this Agreement is terminated pursuant to Section
7.1(b)(ii), 7.1(b)(iv), 7.1(b)(v) (other than as provided in Section 8.1(a)(i)),
7.1(d)(iii) or 7.1(d)(iv) in circumstances where Section 8.1 requires the
payment of Expenses, then the Company shall reimburse Merger Company for the
Expenses incurred to the date of termination on the later of (i) the day that is
two Business Days after such termination and (ii) the day that is two Business
Days after the delivery by Merger Company to the Company of documents reflecting
Expenses incurred. Merger Company shall be entitled to be reimbursed for
Expenses, if any, thereafter incurred by it in connection with enforcing their
right to receive a Termination Fee or reimbursement of Expenses pursuant to this
Section 8.1, with such additional Expenses to be reimbursed concurrently with
the payment of any Termination Fee that may be due pursuant to Section 8.1.

     SECTION 8.2  Amendment; Waiver.

     (a) This Agreement may be amended by the parties hereto, by action taken or
authorized by their respective members or Boards of Directors, at any time
before or after approval by the stockholders of the Company of the matters
presented in connection with the Merger, but after any such approval no
amendment shall be made without the approval of such stockholders if such

party.

Merger Company, Finance Company and the Company contained herein or in any
certificates or other documents delivered prior to or as of the Effective Time
shall not survive beyond the Effective Time. The covenants and agreements of the
parties hereto (including the Surviving Corporation after the Merger) shall
survive the Effective Time without limitation (except for those which, by their
terms, contemplate a shorter survival period).

                           JOHNS MANVILLE CORPORATION

     The undersigned,           , certifies that he is the           of Johns
Manville Corporation (the "Company"), a corporation organized and existing under
and by virtue of the General Corporation Law of the State of Delaware (the
"DGCL"), in accordance with the provisions of Section 242 thereof, DOES HEREBY
CERTIFY:

     That the following amendment was adopted in accordance with the provisions
of Sections 242 of the DGCL:

     1. The name of the Company is Johns Manville Corporation.

     2. This certificate of amendment was approved by the Board of Directors of
the Company and thereafter duly adopted by the stockholders thereof, in
accordance with the provisions of Section 242 of the DGCL.

     3. Article FOURTH of the Restated Certificate of Incorporation is amended
by deleting said Article in its entirety and substituting the following in lieu
thereof:

        "FOURTH: The total number of shares of all classes of capital stock
     which the Company shall have authority to issue is three hundred five
     million (305,000,000) shares, of which three hundred million (300,000,000)
     shares shall be common stock with a par value of $.01 per share ("Common
     Stock") and five million (5,000,000) shares shall be Class TM Preferred
     Stock with a par value of $.01 per share. A description of the different
     classes of stock of the Company and a statement of the designations and the
     powers, preferences and special rights, and the qualifications, limitations
     or restrictions thereof, of the various classes of stock are as follows:

          A. Provisions Relating to Class TM Preferred Stock. The rights,
     preferences, privileges, restrictions and other matters relating to the
     Class TM Preferred Stock are as follows:

             (1) Designation and Amount. The shares of such series shall be
        designated as Class TM Preferred Stock (the "TM Preferred Stock") and
        the number of shares constituting the TM Preferred Stock shall be five
        million (5,000,000).

             (2) Rank. The TM Preferred Stock shall, with respect to dividend
        distributions and distributions upon the liquidation, winding-up and
        dissolution of the Company, rank prior to all classes of common stock of
        the Company, and to each other class of capital stock or series of
        preferred stock hereafter created by the Board, the terms of which do
        not expressly provide that it ranks prior to or pari passu with the TM
        Preferred Stock as to dividend distributions or distributions upon the
        liquidation, winding-up and dissolution of the Company. The TM Preferred
        Stock shall, with respect to dividend distributions and distributions
        upon the liquidation, winding-up and dissolution of the Company, rank
        pari passu with any class of capital stock or series of preferred stock
        hereafter created by the Board, the terms of which expressly provide
        that it ranks pari passu with the TM Preferred Stock as to dividend
        distributions and distributions upon the liquidation, winding-up and
        dissolution of the Company.

             (3) Dividends and Distributions. The holders of shares of TM
        Preferred Stock shall be entitled to receive dividends and distributions
        in an amount and at the time payable as any dividends and distributions
        that are declared on the Common Stock, as if each share of TM Preferred
        Stock is equal to one share of Common Stock.

<PAGE>   163

             (4) Voting Rights. The holders of shares of the TM Preferred Stock
        shall have the following voting rights:

                Each share of TM Preferred Stock shall entitle the holder
           thereof to one vote on all matters submitted to a vote of the
           stockholders of the Company. Except as otherwise provided herein or
           by law, the holders of shares of TM Preferred Stock and the holders
           of shares of Common Stock shall vote together as one class on all
           matters submitted to a vote of stockholders of the Company; provided,
           however, that the affirmative vote of the holders of a majority of
           the outstanding shares of TM Preferred Stock on the relevant record
           date, voting separately as a class, shall be required for any
           amendment, alteration or exchange or similar transaction, of any of
           the provisions of this Certificate which would alter or change the
           powers, preferences or special rights of the shares of TM Preferred
           Stock so as to adversely affect them.

                Except as set forth herein or otherwise required by law, holders
           of TM Preferred Stock shall have no special voting rights and their
           consent as a class shall not be required for taking any corporate
           action.

             (5) Reacquired Shares. Any shares of TM Preferred Stock purchased
        or otherwise acquired by the Company in any manner whatsoever (including
        by reclassification) shall be retired and cancelled promptly after the
        acquisition thereof. All such shares shall, upon their retirement,
        become authorized but unissued shares of preferred stock without
        designation as to series and may be reissued as part of a new series of
        preferred stock to be created by resolution or resolutions of the Board
        of Directors or as otherwise permitted under the DGCL.

             (6) Liquidation, Dissolution or Winding Up. Upon any liquidation,
        dissolution or winding up of the Company, no distribution shall be made
        (1) to the holders of shares of stock ranking junior (either as to
        dividends or upon liquidation, dissolution or winding up) to the TM
        Preferred Stock unless, prior thereto, the holders of shares of TM
        Preferred Stock shall have received $15.625 per share, or (2) to the
        holders of stock ranking on a parity (either as to dividends or
        distributions upon liquidation, dissolution or winding up) with the TM
        Preferred Stock, except distributions made ratably on the TM Preferred
        Stock and all other such parity stock in proportion to the total amounts
        to which the holders of all such shares are entitled as to dividends or
        upon such liquidation, dissolution or winding up.

                For purposes of this Article Fourth, Section 6 only, neither the
           sale, lease, conveyance, exchange or transfer (for cash, shares of
           stock, securities or other consideration) of all or substantially all
           of the property or assets of the Company nor the consolidation or
           merger of the Company with or into one or more corporations shall be
           deemed to be a liquidation, dissolution or winding-up of the affairs
           of the Company (unless such sale, conveyance, exchange or transfer is
           in connection with a dissolution or winding up of the business of the
           Company).

             (7) Redemption. The shares of TM Preferred Stock are not
        redeemable.

             (8) Conversion. The shares of TM Preferred Stock shall be
        automatically converted into an equal number of validly issued, fully
        paid and non-assessable shares of Common Stock in the event that the
        merger (the "Merger") contemplated by the Agreement and Plan of Merger
        among HB Merger LLC, HB Finance LLC and the Company, dated as of June
        22, 2000 (the "Merger Agreement"), shall not have been consummated by
        the Business Day after the transactions contemplated by the Exchange
        Agreement, among the Company, Manville Personal Injury Settlement Trust
        and certain individuals party thereto, dated as of June 22, 2000 (the
        "Exchange Agreement"), are consummated. If the Merger is not so
        consummated, or if the Merger Agreement is terminated, each holder of a
        certificate representing TM Preferred Stock shall, after the earlier to
        occur of such events, be entitled to receive certificates representing

                                       B-2
<PAGE>   164

        Common Stock upon presentation of certificates representing TM Preferred
        Stock as provided for in the Exchange Agreement.

             (9) Restriction on Transferability. Except as contemplated by the
        Merger Agreement and the Exchange Agreement, the shares of TM Preferred
        Stock may not be transferred or pledged in any manner whatsoever.

             (10) Reports. So long as any shares of TM Preferred Stock are
        outstanding, the Company will furnish holders thereof by first class
        mail, postage prepaid, at such holder's address as the same appears on
        the stock register of the Company, with the quarterly and annual
        financial reports that the Company is required to file with the
        Securities and Exchange Commission pursuant to Section 13 or Section
        15(d) of the Securities Exchange Act of 1934, as amended, or, in the
        event that the Company is not required to file such reports, reports
        containing the same financial information as would be required in such
        reports.

             (11) General Provisions.

                (a) If any of the TM Preferred Stock certificates shall be
           mutilated, lost, stolen or destroyed, the Company shall issue, in
           exchange and in substitution for and upon cancellation of the
           mutilated TM Preferred Stock certificate, or in lieu of and
           substitution for the TM Preferred Stock certificate lost, stolen or
           destroyed, a new TM Preferred Stock certificate of like tenor and
           representing an equivalent amount of shares of TM Preferred Stock,
           but only upon receipt of evidence of such loss, theft or destruction
           of such TM Preferred Stock certificate and indemnity, if requested,
           satisfactory to the Company.

                (b) The term "outstanding," when used in reference to shares of
           a specific series or class of capital stock of the Company, shall
           mean issued shares, excluding shares held by the Company or a
           subsidiary.

                (c) No holder of shares of TM Preferred Stock will, except as
           otherwise provided in subparagraph (8) above, by virtue of such
           holder's holding such shares, possess any preemptive rights to
           subscribe for or acquire any unissued shares of capital stock of the
           Company (whether now or hereafter authorized) or securities of the
           Company convertible into, or exercisable or exchangeable for, shares
           of capital stock of the Company.

                (d) Each holder of TM Preferred Stock, by acceptance thereof,
           acknowledges and agrees that payments of dividends on or liquidation
           preference of TM Preferred Stock, and exchange, redemption and
           repurchase of TM Preferred Stock, by the Company are subject to
           restrictions on the Company contained in certain credit and financing
           agreements binding on the Company or certain of its subsidiaries.

                (e) If any payment, redemption, exchange or other action shall
           be required by the terms hereof to be made or taken on a day that is
           not a Business Day, such payment, redemption, exchange or other
           action shall be made or taken on the immediately succeeding Business

           day on which commercial banks in the State of Delaware or the State
           of New York are authorized by law to close.

The Board of Directors
Johns Manville Corporation
717 17th Street
Denver, Colorado 80202

Lady and Gentlemen:

     You have requested our opinion as to the fairness, from a financial point
of view, to the stockholders of Johns Manville Corporation (the "Company")
entitled to receive the Common Stock Merger Consideration (as defined below)
(the "Public Stockholders") of the consideration to be received by them in
connection with the proposed merger (the "Merger") of the Company with HB Merger
LLC (the "Merger Company"), a Delaware corporation jointly owned by Bear,
Stearns Merchant Fund Corp. and Hicks, Muse, Tate & Furst, Inc. (the
"Sponsors"). Pursuant to the Agreement and Plan of Merger, dated as of June 22,
2000 (the "Agreement"), among the Company, the Merger Company and HB Finance
LLC, the Merger Company will be merged with and into the Company, and the Public
Stockholders of the Company will receive for each share of Common Stock, par
value $0.01 per share, of the Company held by them consideration (the "Common
Stock Merger Consideration") equal to $13.625 per share in cash and 0.02 fully
paid and nonassessable shares of Series A Redeemable PIK Preferred Stock (the
"Preferred Stock") of the Company as survivor of the Merger (in such capacity,
the "Surviving Corporation").

     In arriving at our opinion, we have reviewed (i) the Agreement, including
the terms of the Preferred Stock appended thereto; (ii) certain publicly
available information concerning the business of the Company and of certain
other companies engaged in businesses comparable to those of the Company, and
the reported market prices for certain other companies' securities deemed
comparable; (iii) publicly available terms of certain transactions involving
companies comparable to the Company and the terms of other transactions we
deemed relevant; (iv) current and historical market prices of the common stock
of the Company; (v) the audited financial statements of the Company for the
fiscal year ended December 31, 1999, and the unaudited financial statements of
the Company for the period ended March 31, 2000; (vi) certain agreements with
respect to outstanding indebtedness or obligations of the Company; (vii) certain
internal financial analyses and forecasts prepared by the Company and its
management; (viii) the Trust Voting Agreement, dated as of June 22, 2000,
between the Merger Company and the Manville Personal Injury Settlement Trust
(the "Trust"); (ix) the commitment letters relating to the financing
contemplated by the Merger Company; (x) the Tax Matters and Amended Trust
Relationship Agreement, dated as of June 22, 2000, between the Trust and the
Company; and (xi) certain other agreements we deemed relevant.

     In addition, we have held discussions with certain members of the
management of the Company and the Sponsors with respect to certain aspects of
the Merger, and the past and current business operations of the Company, the
financial condition and future prospects and operations of the Company, the
effects of the Merger on the financial condition and future prospects of the
Company, and certain other matters we believed necessary or appropriate to our
inquiry. We have visited certain representative facilities of the Company, and
reviewed such other financial studies and analyses and considered such other
information as we deemed appropriate for the purposes of this opinion.

     In giving our opinion, we have relied upon and assumed, without independent
verification, the accuracy and completeness of all information that was publicly
available or was furnished to us by the Company or the Sponsors or otherwise
reviewed by us, and we have not assumed any responsibility or liability
therefor. We have not conducted any valuation or appraisal of any assets or
liabilities, nor have any such valuations or appraisals been provided to us. In
relying on financial analyses and forecasts

                                       C-1
<PAGE>   167

provided to us, we have assumed that they have been reasonably prepared based on
assumptions reflecting the best currently available estimates and judgments by
management as to the expected future results of operations and financial
condition of the Company to which such analyses or forecasts relate. We have
also assumed that the Merger will have the tax consequences described in
discussions with, and materials furnished to us by, representatives of the
Company, and that the other transactions contemplated by the Agreement will be
consummated as described in the Agreement. We have relied as to all legal
matters relevant to rendering our opinion upon the advice of counsel.

     We note that the proposed Merger follows a full public auction process in
which we broadly solicited offers for the Company from January through April
1999 and that subsequent to such auction process the Company and we have had
discussions with several other potential buyers which did not result in a
business combination transaction and that we have taken such circumstances into
account in rendering our opinion.

     Our opinion is necessarily based on economic, market and other conditions
as in effect on, and the information made available to us as of, the date
hereof. It should be understood that subsequent developments may affect this
opinion and that we do not have any obligation to update, revise, or reaffirm
this opinion. We are expressing no opinion herein as to whether or at what price
the Preferred Stock will trade at any future time.

     We have acted as financial advisor to the Company and the Special Committee
of the Board of Directors of the Company with respect to the proposed Merger and
have received a fee from the Company for our services. We will also receive an
additional fee if the proposed Merger is consummated. From time to time, J.P.
Morgan and its affiliates have provided investment banking services to Hicks,
Muse, Tate & Furst, Inc. for which they have received customary compensation. In
the ordinary course of their businesses, J.P. Morgan and its affiliates may
actively trade the debt and equity securities of the Company or the Sponsors
and/or affiliates thereof, as applicable, for their own account or for the
accounts of customers and, accordingly, they may at any time hold long or short
positions in such securities.

     On the basis of and subject to the foregoing, it is our opinion as of the
date hereof that the Common Stock Merger Consideration to be paid to the Public
Stockholders in the proposed Merger is fair, from a financial point of view, to
such Public Stockholders.

     This letter is provided to the Board of Directors of the Company in
connection with and for the purposes of its evaluation of the Merger. This
opinion does not constitute a recommendation to any stockholder of the Company
as to how such stockholder should vote with respect to the Merger. This opinion
may not be disclosed, referred to, or communicated (in whole or in part) to any
third party for any purpose whatsoever except with our prior written consent in
each instance. This opinion may be reproduced in full in any proxy or
information statement mailed to stockholders of the Company but may not
otherwise be disclosed publicly in any manner without our prior written approval
and must be treated as confidential.

                                            Very truly yours,

                                            J.P. MORGAN SECURITIES INC.

Johns Manville Corporation

Denver, Colorado 80202

Lady and Gentlemen:

     You have requested our opinion as to the fairness, from a financial point
of view, to the stockholders (other than Manville Personal Injury Settlement
Trust (the "Trust") (the "Public Stockholders") of Johns Manville Corporation
(the "Company") of the consideration to be paid by the Company to the Trust
pursuant to the Tax Matters and Amended Trust Relationship Agreement, dated as
of June 22, 2000 (the "Tax Agreement"), between the Company and the Trust.
Pursuant to the Tax Agreement, the Company will pay the Trust $90,000,000 and
will be indemnified by the Trust for any taxes due on income earned by the
Designated Settlement Fund (as defined in the Tax Agreement) of the Trust,
including taxes pursuant to Section 1807(a)(7)(C) of the Tax Reform Act of 1986.
The entry into the Tax Agreement and the consummation of the transactions
contemplated hereby is occurring as part of the arrangements to be entered into
by the Company in connection with the proposed merger (the "Merger") of the
Company with HB Merger LLC (the "Merger Company"), a Delaware corporation
jointly owned by Bear, Stearns Merchant Fund Corp. and Hicks, Muse, Tate &
Furst, Inc. (the "Sponsors") pursuant to the Agreement and Plan of Merger, dated
as of June 22, 2000 (the "Merger Agreement"), among the Company, the Merger
Company and HB Finance LLC.

     In arriving at our opinion, we have reviewed (i) the Tax Agreement; and the
Merger Agreement; (ii) the audited financial statements of the Company and the
Trust for the fiscal year ended December 31, 1999, and the unaudited financial
statements of the Company for the period ended March 31, 2000; (iii) certain
internal financial analyses and forecasts prepared by the Company and its
management; (iv) certain information regarding Trust income projections and
forecasted amounts of asbestos injury claims filed and settled, provided to the
Company by the Trust; (v) certain other relevant agreements; and (vi) the Trust
Voting Agreement, dated as of June 22, 2000, between the Merger Company and the
Trust.

     In addition, we have held discussions with certain members of the
management of the Company and the Trust with respect to certain aspects of Tax
Agreement, and the past and current business operations of the Company and the
Trust, the financial condition and future prospects and operations of the
Company and the Trust, the effects of the Tax Agreement on the financial
condition and future prospects of the Company and the Trust, and certain other
matters we believed necessary or appropriate to our inquiry. We have also held
discussions with certain members of the management of the Company and the
Sponsors with respect to certain aspects of the Merger, and certain other
matters we believed necessary or appropriate to our inquiry. We have reviewed
such other financial studies and analyses and considered such other information
as we deemed appropriate for the purposes of this opinion.

     In giving our opinion, we have relied upon and assumed, without independent
verification, the accuracy and completeness of all information that was publicly
available or was furnished to us by the Company, the Trust or the Sponsors or
otherwise reviewed by us, and we have not assumed any responsibility or
liability therefor. We have not conducted any valuation or appraisal of any
assets or liabilities (other than our valuation analysis of the Tax Liability),
nor have any such valuations or appraisals been provided to us. In relying on
financial analyses and forecasts provided to us, we have assumed that they have
been reasonably prepared based on assumptions reflecting the best currently
available estimates and judgments by management as to the expected future
results of operations and financial condition of the Company or the Trust to
which such analyses or forecasts relate. We have also assumed that the Merger

furnished to us by, representatives of the Company, and, as agreed by the
Company and the Trust, that the Trust will not be subject to state income tax
obligations and will be taxed for federal income tax purposes at an effective
rate of 15%. We have further assumed that the other transactions contemplated by
the Tax Agreement and the Merger Agreement will be consummated as described in
such agreements. We have relied as to all legal matters relevant to rendering
our opinion upon the advice of counsel.

     Our opinion is necessarily based on economic, market and other conditions
as in effect on, and the information made available to us as of, the date
hereof. It should be understood that subsequent developments may affect this
opinion and that we do not have any obligation to update, revise, or reaffirm
this opinion.

     We have acted as financial advisor to the Company and the Board of
Directors of the Company with respect to the proposed Merger and have received a
fee from the Company for our services. We will also receive an additional fee if
the proposed Merger is consummated. From time to time, J.P. Morgan and its
affiliates have provided investment banking services to Hicks, Muse, Tate &
Furst, Inc. for which they have received customary compensation. In the ordinary
course of their businesses, J.P. Morgan and its affiliates may actively trade
the debt and equity securities of the Company or the Sponsors and/or affiliates
thereof, as applicable, for their own account or for the accounts of customers
and, accordingly, they may at any time hold long or short positions in such
securities.

     On the basis of and subject to the foregoing, it is our opinion as of the
date hereof that the consideration being paid to the Trust pursuant to the terms
of the Tax Agreement is fair, from a financial point of view, to the Public
Stockholders.

     This letter is provided to the Board of Directors of the Company in
connection with and for the purposes of its evaluation of the Merger and the
transactions contemplated by the Tax Agreement. This opinion does not constitute
a recommendation to any stockholder of the Company as to how such stockholder
should vote with respect to the Merger. This opinion may not be disclosed,
referred to, or communicated (in whole or in part) to any third party for any
purpose whatsoever except with our prior written consent in each instance. This
opinion may be reproduced in full in any proxy or information statement mailed
to stockholders of the Company but may not otherwise be disclosed publicly in
any manner without our prior written approval and must be treated as
confidential.

                                            Very truly yours,

                                            J.P. MORGAN SECURITIES INC.

PERSONAL AND CONFIDENTIAL

June 22, 2000

Board of Trustees and Trustees
Manville Personal Injury Settlement Trust
143 Bedford Road
Suite 200
Katonah, NY 10536

GENTLEMEN:

     You have requested our opinion as to the fairness from a financial point of
view to the Manville Personal Injury Settlement Trust (the "Trust") of the Trust
Merger Consideration (as defined below) to be received by the Trust in exchange
for the shares of Company Common Stock (as defined below) owned by the Trust as
of the date hereof (the "Shares") pursuant to the Exchange Agreement, dated as
of June 22, 2000, among Johns Manville Corporation (the "Company"), the Trust
and certain individuals listed or to be listed therein (the "Exchange
Agreement") and the Agreement and Plan of Merger, dated as of June 22, 2000 (the
"Agreement"), among the Company, and HB Merger LLC (the "Merger Company") and HB
Finance LLC, companies formed by Hicks Muse Tate & Furst Incorporated ("Hicks
Muse") and Bear Stearns Merchant Funding Corp. ("Bear Stearns", and together
with Hicks Muse, the "Sponsor Group"), which Agreement provides, among other
things, for the merger (the "Merger") of Merger Company with and into the
Company, with the Company continuing as the surviving corporation (the
"Surviving Corporation") in the Merger. The Exchange Agreement provides for the
exchange of shares of Company Common Stock for shares of TM Preferred Stock, as
described below.

     We understand that, pursuant to the Exchange Agreement, prior to the
effective date of the Merger, the Trust will have exchanged 3,200,000 shares of
Company Common Stock (as defined below) owned by the Trust into 3,200,000 shares
of Class TM Preferred Stock, par value $0.01 per share, of the Company (the "TM
Preferred Stock"). Pursuant to the Agreement, (a) each issued and outstanding
share of common stock, par value $0.01 per share, of the Company (the "Company
Common Stock") owned by the Trust will be converted into the right to receive
(x) $13.625 in cash and (y) 0.02 fully paid and non-assessable shares of Series
A Redeemable Preferred Stock, par value $0.01 per share, of the Surviving
Corporation ("Surviving Corporation Preferred Stock"), each full share having a
liquidation preference of $100, (together, the "Common Stock Merger
Consideration") and (b) each issued and outstanding share of TM Preferred Stock
owned by the Trust will be converted into 0.6 of a share of common stock, par
value $0.01 per share, of the Surviving Corporation (the "Surviving Corporation
Common Stock") and 0.4 fully paid and non-assessable shares of Series B Junior
Redeemable Convertible Preferred Stock, par value $0.01 per share, of the
Surviving Corporation (the "Junior Preferred Stock"), each full share having a
liquidation preference of $15.625 (together, the "TM Merger Consideration" and
together with the Common Stock Merger Consideration, the "Trust Merger
Consideration").

     Goldman, Sachs & Co., as part of its investment banking business, is
continually engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings, competitive
biddings, secondary distributions of listed and unlisted securities, private
placements and valuations for estate, corporate and other purposes. We are
familiar with the Trust, having

                                       E-1
<PAGE>   171

provided various investment banking services from time to time, including having
been engaged by the Trust in 1992 to assist it on an ongoing basis in its
analysis, consideration and negotiation of various financial alternatives
available to it with respect to the Trust's ownership interest in the Company.
In connection with such engagement, we have acted as financial advisor to the
Trust in regard to the Profit
Sharing Exchange Agreement, dated as of October 25, 1995, between the Company
and the Trust; and we have, on a periodic basis, participated in a review of
strategic alternatives by the Trust with respect to its ownership position in
the Company. We have also acted as the Trust's financial advisor in connection
with, and have participated in certain of the negotiations leading to, the
Exchange Agreement and the Agreement. In addition, we are familiar with the
Company, having acted as financial advisor to the Special Advisor to the United
States Bankruptcy Court in evaluating the assets and liabilities of the Company
and the Trust in 1990; and having acted in 1994 as lead underwriter on the $400
million secondary offering by the Trust of 10.875% Notes due December 2004, for
Schuller International Group, Inc., a wholly owned subsidiary of the Company. We
also have from time to time provided numerous investment banking services to
Hicks Muse and several of its portfolio companies, and we may provide investment
banking services to Hicks Muse or Bear Stearns and their respective subsidiaries
and affiliates in the future. We provide a full range of financial advisory and
securities services and, in the course of our normal trading activities, we may
from time to time effect transactions and hold positions in securities,
including derivative securities, of the Company for our own account and the
accounts of our customers.

     In connection with this opinion, we have reviewed, among other things: (i)
the Agreement and the exhibits and annexes thereto, including the certificates
of designation relating to the TM Preferred Stock, the Surviving Corporation
Preferred Stock, and the Junior Preferred Stock, and the Stockholders' Agreement
relating to the Surviving Corporation; (ii) the Tax Matters and Amended Trust
Relationship Agreement between the Company and the Trust dated as of June 22,
2000 (the "Tax Agreement"); (iii) the Trust Voting Agreement between the Trust
and Merger Company dated as of June 22, 2000; (iv) Annual Reports to
Stockholders and Annual Reports on Form 10-K of the Company for the five years
ended December 31, 1999; (v) certain interim reports to stockholders and
Quarterly Reports on Form 10-Q of the Company; and (vi) certain internal
financial analyses and forecasts for the Company prepared by the Company's
management. We also have held discussions with members of the senior management
of the Company regarding their assessment of the past and current business
operations, financial condition and future prospects of the Company. In
addition, we have reviewed the reported price and trading activity for the
Company Common Stock, compared certain financial and stock market information
for the Company with similar information for certain other companies the
securities of which are publicly traded, reviewed the financial terms of certain
recent business combinations in the building products industry specifically, and
in other industries generally, and performed such other studies and analyses as
we considered appropriate.

     We have relied upon the accuracy and completeness of all the financial and
other information reviewed by us and have assumed such accuracy and completeness
for purposes of rendering this opinion. In rendering our opinion, we took into
account, with your consent, management's assessment of the risks and
uncertainties associated with the Company achieving management's forecasts in
the amounts and at the times indicated therein. In addition, we have not made an
independent evaluation or appraisal of the assets and liabilities of the
Company, and we have not been furnished with any such evaluation or appraisal.
We have relied upon the advice the Trust has received from its legal counsel and
tax advisors as to all legal and tax matters in connection with our
consideration of the proposed transaction.

     We note that the Company made a public announcement in January 1999 of its
intention to undertake a review of strategic alternatives available to maximize
shareholder value, including a possible sale or merger of the Company, and in
April 1999 made a subsequent public announcement that discussions with
potentially interested parties did not result in an acceptable offer for the
sale or merger of the Company. In rendering this opinion, we have taken into
account the process in which a significant
number of third parties were contacted during the review in 1999 of strategic
alternatives regarding their interest in pursuing a business combination with
the Company and the results of that process. We also note that during the
exclusivity period in which negotiations were being held with the Sponsor Group,
a

                                       E-2
<PAGE>   172

third party indicated an interest in acquiring the Company at a price of $15.50
in cash per share of Company Common Stock. We understand that, among other
factors, given the exclusivity assurances required by the Sponsor Group, the
Company determined to continue its exclusivity relationship with the Sponsor
Group.

     Our advisory services and the opinion expressed herein are provided for the
information and assistance of the Board of Trustees of the Trust in connection
with its consideration of the Exchange Agreement and the Agreement. Our opinion
is not provided for the information or assistance of either the board of
directors or other shareholders of the Company, nor does it constitute a
recommendation as to how the Trust or any other shareholders of the Company
should vote with respect to the Merger. Our opinion does not address the
treatment of the Trust and the other shareholders of the Company as among
themselves. We also are not expressing any opinion as to the impact of the
Merger on the solvency or viability of the Surviving Corporation or the ability
of the Surviving Corporation to pay its obligations when they become due.

     We note that pursuant to the terms of the Tax Agreement, the Trust will be
paid $90 million in cash in consideration for the Trust's agreement to pay all
applicable taxes attributable to the income and gains of the Designated
Settlement Fund of the Trust for all periods beginning on or after the time the
$90 million payment is made (the "Tax Settlement"). The $90 million payment and
the other terms related thereto were determined based on extensive arm's length
negotiations between the Company and the Trust, in which we participated. In
rendering this opinion, we are not opining on the terms of the Tax Settlement.

     We are not expressing a view as to the prices at which actual transactions
involving the Surviving Corporation Preferred Stock will occur, which will be
dependent upon and fluctuate with dividend rates generally, market conditions,
general economic conditions, the financial condition and prospects of the
Surviving Corporation and other factors which generally influence the price of
similar securities. We also note that the Trust has agreed not to transfer the
shares of Surviving Corporation Preferred Stock to be received by the Trust for
a period of up to 180 days following the closing of the Merger, and that
thereafter, given the terms of the Surviving Corporation Preferred Stock and the
percentage of that issue owned by the Trust, it is very likely that those shares
will be highly illiquid.

     Based upon and subject to the foregoing and based upon such other matters
as we consider relevant, it is our opinion that as of the date hereof the Trust
Merger Consideration to be received by the Trust in exchange for its Shares
pursuant to the Exchange Agreement and the Agreement is fair from a financial
point of view to the Trust.

                                            Very truly yours,

                                            GOLDMAN, SACHS & CO.

              SECTION 262 OF THE DELAWARE GENERAL CORPORATION LAW

     262 APPRAISAL RIGHTS -- (a) Any stockholder of a corporation of this State
who holds shares of stock on the date of the making of a demand pursuant to
subsection (d) of this section with respect to such shares, who continuously
holds such shares through the effective date of the merger or consolidation, who
has otherwise complied with subsection (d) of this section and who has neither
voted in favor of the merger or consolidation nor consented thereto in writing
pursuant to sec. 228 of this title shall be entitled to an appraisal by the
Court of Chancery of the fair value of the stockholder's shares of stock under
the circumstances described in subsections (b) and (c) of this section. As used
in this section, the word "stockholder" means a holder of record of stock in a
stock corporation and also a member of record of a nonstock corporation; the
words "stock" and "share" mean and include what is ordinarily meant by those
words and also membership or membership interest of a member of a nonstock
corporation; and the words "depository receipt" mean a receipt or other
instrument issued by a depository representing an interest in one or more
shares, or fractions thereof, solely of stock of a corporation, which stock is
deposited with the depository.

     (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to sec. 251 (other than a merger effected pursuant to
sec. 251(g) of this title), sec. 252, sec. 254, sec. 257, sec. 258, sec. 263 or
sec. 264 of this title:

          (1) Provided, however, that no appraisal rights under this section
     shall be available for the shares of any class or series of stock, which
     stock, or depository receipts in respect thereof, at the record date fixed
     to determine the stockholders entitled to receive notice of and to vote at
     the meeting of stockholders to act upon the agreement of merger or
     consolidation, were either (i) listed on a national securities exchange or
     designated as a national market system security on an interdealer quotation
     system by the National Association of Securities Dealers, Inc. or (ii) held
     of record by more than 2,000 holders; and further provided that no
     appraisal rights shall be available for any shares of stock of the
     constituent corporation surviving a merger if the merger did not require
     for its approval the vote of the stockholders of the surviving corporation
     as provided in subsection (f) of sec. 251 of this title.

          (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
     under this section shall be available for the shares of any class or series
     of stock of a constituent corporation if the holders thereof are required
     by the terms of an agreement of merger or consolidation pursuant to
     sec.sec. 251, 252, 254, 257, 258, 263 and 264 of this title to accept for
     such stock anything except:

             a. Shares of stock of the corporation surviving or resulting from
        such merger or consolidation, or depository receipts in respect thereof;

             b. Shares of stock of any other corporation, or depository receipts
        in respect thereof, which shares of stock (or depository receipts in
        respect thereof) or depository receipts at the effective date of the
        merger or consolidation will be either listed on a national securities
        exchange or designated as a national market system security on an
        interdealer quotation system by the National Association of Securities
        Dealers, Inc. or held of record by more than 2,000 holders;

             c. Cash in lieu of fractional shares or fractional depository
        receipts described in the foregoing subparagraphs a. and b. of this
        paragraph; or

             d. Any combination of the shares of stock, depository receipts and
        cash in lieu of fractional shares or fractional depository receipts
        described in the foregoing subparagraphs a., b. and c. of this
        paragraph.

          (3) In the event all of the stock of a subsidiary Delaware corporation
     party to a merger effected under sec. 253 of this title is not owned by the
     parent corporation immediately prior to the merger, appraisal rights shall
     be available for the shares of the subsidiary Delaware corporation.
                                       F-1
<PAGE>   174

     (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.

     (d) Appraisal rights shall be perfected as follows:

          (1) If a proposed merger or consolidation for which appraisal rights
     are provided under this section is to be submitted for approval at a
     meeting of stockholders, the corporation, not less than 20 days prior to
     the meeting, shall notify each of its stockholders who was such on the
     record date for such meeting with respect to shares for which appraisal
     rights are available pursuant to subsection (b) or (c) hereof that
     appraisal rights are available for any or all of the shares of the
     constituent corporations, and shall include in such notice a copy of this
     section. Each stockholder electing to demand the appraisal of such
     stockholder's shares shall deliver to the corporation, before the taking of
     the vote on the merger or consolidation, a written demand for appraisal of
     such stockholder's shares. Such demand will be sufficient if it reasonably
     informs the corporation of the identity of the stockholder and that the
     stockholder intends thereby to demand the appraisal of such stockholder's
     shares. A proxy or vote against the merger or consolidation shall not
     constitute such a demand. A stockholder electing to take such action must
     do so by a separate written demand as herein provided. Within 10 days after
     the effective date of such merger or consolidation, the surviving or
     resulting corporation shall notify each stockholder of each constituent
     corporation who has complied with this subsection and has not voted in
     favor of or consented to the merger or consolidation of the date that the
     merger or consolidation has become effective; or

          (2) If the merger or consolidation was approved pursuant to sec. 228
     or sec. 253 of this title, each constituent corporation, either before the
     effective date of the merger or consolidation or within ten days
     thereafter, shall notify each of the holders of any class or series of
     stock of such constituent corporation who are entitled to appraisal rights
     of the approval of the merger or consolidation and that appraisal rights
     are available for any or all shares of such class or series of stock of
     such constituent corporation, and shall include in such notice a copy of
     this section; provided that, if the notice is given on or after the
     effective date of the merger or consolidation, such notice shall be given
     by the surviving or resulting corporation to all such holders of any class
     or series of stock of a constituent corporation that are entitled to
     appraisal rights. Such notice may, and, if given on or after the effective
     date of the merger or consolidation, shall, also notify such stockholders
     of the effective date of the merger or consolidation. Any stockholder
     entitled to appraisal rights may, within 20 days after the date of mailing
     of such notice, demand in writing from the surviving or resulting
     corporation the appraisal of such holder's shares. Such demand will be
     sufficient if it reasonably informs the corporation of the identity of the
     stockholder and that the stockholder intends thereby to demand the
     appraisal of such holder's shares. If such notice did not notify
     stockholders of the effective date of the merger or consolidation, either
     (i) each such constituent corporation shall send a second notice before the
     effective date of the merger or consolidation notifying each of the holders
     of any class or series of stock of such constituent corporation that are
     entitled to appraisal rights of the effective date of the merger or
     consolidation or (ii) the surviving or resulting corporation shall send
     such a second notice to all such holders on or within 10 days after such
     effective date; provided, however, that if such second notice is sent more
     than 20 days following the sending of the first notice, such second notice
     need only be sent to each stockholder who is entitled to appraisal rights
     and who has demanded appraisal of such holder's shares in accordance with
     this subsection. An affidavit of the secretary or assistant secretary or of
     the transfer agent of the corporation that is required to give either
     notice that such notice has been given shall, in the absence of fraud, be
     prima facie evidence of the facts stated therein. For purposes of
     determining the stockholders entitled to receive either notice, each
     constituent corporation may fix, in advance, a record date that shall be
     not more than 10 days prior to the date the notice is given, provided, that
     if the notice is given on or after the effective date of the
                                       F-2
<PAGE>   175

     merger or consolidation, the record date shall be such effective date. If
     no record date is fixed and the notice is given prior to the effective
     date, the record date shall be the close of business on the day next
     preceding the day on which the notice is given.

     (e) Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise entitled to
appraisal rights, may file a petition in the Court of Chancery demanding a
determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw such stockholder's demand for appraisal and to accept the terms offered
upon the merger or consolidation. Within 120 days after the effective date of
the merger or consolidation, any stockholder who has complied with the
requirements of subsections (a) and (d) hereof, upon written request, shall be
entitled to receive from the corporation surviving the merger or resulting from
the consolidation a statement setting forth the aggregate number of shares not
voted in favor of the merger or consolidation and with respect to which demands
for appraisal have been received and the aggregate number of holders of such
shares. Such written statement shall be mailed to the stockholder within 10 days
after such stockholder's written request for such a statement is received by the
surviving or resulting corporation or within 10 days after expiration of the
period for delivery of demands for appraisal under subsection (d) hereof,
whichever is later.

     (f) Upon the filing of any such petition by a stockholder, service of a
copy thereof shall be made upon the surviving or resulting corporation, which
shall within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the addresses
therein stated. Such notice shall also be given by 1 or more publications at
least 1 week before the day of the hearing, in a newspaper of general
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems advisable. The forms of the notices by mail and by publication
shall be approved by the Court, and the costs thereof shall be borne by the
surviving or resulting corporation.

     (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.

     (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal prior
to the final determination of the stockholder entitled to an appraisal. Any
stockholder whose name appears on the list filed by the surviving or resulting
corporation pursuant to subsection (f) of this section and who has submitted
such stockholder's certificates of stock to the Register in Chancery, if such is
required, may

                                       F-3
<PAGE>   176

participate fully in all proceedings until it is finally determined that such
stockholder is not entitled to appraisal rights under this section.

     (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.

     (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.

     (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded appraisal rights as provided in subsection (d) of
this section shall be entitled to vote such stock for any purpose or to receive
payment of dividends or other distributions on the stock (except dividends or
other distributions payable to stockholders of record at a date which is prior
to the effective date of the merger or consolidation); provided, however, that
if no petition for an appraisal shall be filed within the time provided in
subsection (e) of this section, or if such stockholder shall deliver to the
surviving or resulting corporation a written withdrawal of such stockholder's
demand for an appraisal and an acceptance of the merger or consolidation, either
within 60 days after the effective date of the merger or consolidation as
provided in subsection (e) of this section or thereafter with the written
approval of the corporation, then the right of such stockholder to an appraisal
shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court
of Chancery shall be dismissed as to any stockholder without the approval of the
Court, and such approval may be conditioned upon such terms as the Court deems
just.

     (l) The shares of the surviving or resulting corporation to which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation.

               FORM OF TERMS, PREFERENCES, RIGHTS AND LIMITATIONS
                                       OF
                    SERIES A REDEEMABLE PIK PREFERRED STOCK
                                       OF
                           JOHNS MANVILLE CORPORATION

     The rights, preferences, privileges, restrictions and other matters
relating to the Series A Redeemable PIK Preferred Stock are as follows:

     (1) Designation and Amount. The shares of such series of preferred stock,
par value $.01 per share, of Johns Manville Corporation (the "Company") shall be
designated as Series A Redeemable PIK Preferred Stock (the "PIK Preferred
Stock"), and the number of shares constituting the PIK Preferred Stock shall be
8,000,000. Such number of shares may be increased or decreased by resolution of
the Board of Directors of the Company (the "Board"); provided, however, that:
(i) in no event shall shares of PIK Preferred Stock be issued other than
pursuant to the Agreement and Plan of Merger dated as of June 22, 2000 among HB
Merger LLC, HB Finance LLC and the Company (the "Merger Agreement"), or as
pay-in-kind dividends on outstanding shares of PIK Preferred Stock; (ii) no
decrease shall reduce the number of shares of PIK Preferred Stock to a number
less than the number of shares then outstanding plus the number of shares
issuable as pay-in-kind dividends on the PIK Preferred Stock through the
Scheduled Redemption Date (as hereinafter defined); and (iii) the Board shall,
from time to time, increase such number of reserved shares to the extent, if
any, that the number of previously reserved shares shall be inadequate for the
issuance of such pay-in-kind dividends.

     (2) Rank. The PIK Preferred Stock shall, with respect to dividends and
distributions upon the liquidation, winding-up and dissolution of the Company,
rank prior to all classes of common stock of the Company, to the Series B
Convertible Preferred Stock, par value $.01 per share, of the Company (the
"Junior Preferred Stock") and to each other class of capital stock or series of
preferred stock hereafter created by the Board not in violation of the terms
hereof, the terms of which do not expressly provide that it ranks prior to or
pari passu with the PIK Preferred Stock as to dividends and distributions upon
the liquidation, winding-up and dissolution of the Company (collectively
referred to with the common stock of the Company and the Junior Preferred Stock
as "Junior Securities"). The PIK Preferred Stock shall, with respect to
dividends and distributions upon the liquidation, winding-up and dissolution of
the Company, rank pari passu with any class of capital stock or series of
preferred stock hereafter created by the Board not in violation of the terms
hereof, the terms of which expressly provide that it ranks pari passu with the
PIK Preferred Stock as to dividends and distributions upon the liquidation,
winding-up and dissolution of the Company ("Parity Securities"). The PIK
Preferred Stock shall, with respect to dividends and distributions upon the
liquidation, winding-up and dissolution of the Company, rank junior to each
class of capital or series of preferred stock hereafter created by the Board
which has been approved by the holders of the PIK Preferred Stock in accordance
herewith, the terms of which expressly provide that it ranks prior to the PIK
Preferred Stock as to dividends and distributions upon the liquidation,
winding-up and dissolution of the Company ("Senior Securities"); provided,
however, that no such approval by the holders of the PIK Preferred Stock shall
be required with respect to such liquidation preference or stated amount of
shares of any class of capital stock or series of preferred stock of the Company
or any of its direct or indirect subsidiaries (including any pay-in-kind
dividends paid thereon) as shall be issued in lieu of up to $600,000,000 of
initial proceeds from the sale of debt securities as part of the Permanent Debt
Financing (as hereinafter defined) and the first refinancing (if any) of the
Permanent Debt Financing.

     (3) Dividends and Distributions. The holders of shares of PIK Preferred
Stock, in preference to the holders of shares of any Junior Securities, shall be
entitled to receive, when, as and if declared by the Board out of funds legally
available therefor, cumulative dividends, at a rate of 13.0% per annum (as such
rate may be increased in accordance with the terms hereof, the "Dividend Rate")
of the Liquidation Preference (as hereinafter defined) (computed on the basis of
a 360-day year and taking into account the

                                       G-1
<PAGE>   178

different dividend rates, if any, during the course of such year) payable in
cash on [insert date which is six-month anniversary of Effective Date] and
[insert date which is twelve-month anniversary of Effective Date] of each year
(each a "Dividend Payment Date"), or at the option of the Company, on each
Dividend Payment Date on or prior to the seventh anniversary of the Effective
Date (as hereinafter defined), by validly issuing fully paid and non-assessable
shares of PIK Preferred Stock with an aggregate Liquidation Preference equal to
the amount of the dividends to be paid. All undeclared dividends and declared
but unpaid dividends shall compound on a semi-annual basis at the then
applicable Dividend Rate, without any duplication when and if the dividends are
actually paid. In the event (i) that the Company fails to redeem the PIK
Preferred Stock on the Scheduled Redemption Date, pursuant to Section 8(a)
hereof, or (ii) of a Change of Control (as hereinafter defined) and the failure
of the Company to redeem the PIK Preferred Stock pursuant to Section 8(c)
hereof, the Dividend Rate then applicable shall be increased to 15.0% per annum.

          (a) The Company shall take all action permitted under applicable law
     to permit the payment of dividends, including through revaluation of assets
     to make funds legally available for such payment.

          (b) All dividends and distributions paid with respect to shares of PIK
     Preferred Stock shall be paid pro rata to the holders of the PIK Preferred
     Stock. All shares of PIK Preferred Stock issued in respect of any Dividend
     Payment Date shall be deemed issued on the applicable Dividend Payment
     Date, and will thereupon be duly authorized, validly issued, fully paid and
     non-assessable and free and clear of all liens and charges. On and after a
     Dividend Payment Date, until certificates representing additional shares of
     PIK Preferred Stock shall have been issued, the certificates representing
     such shares held by a holder on the Dividend Record Date shall represent
     not only such existing shares, but also the additional shares of PIK
     Preferred Stock issued to such holder pursuant to such dividend. "Dividend
     Record Date" means with respect to the dividend payable on [insert date
     which is six-month anniversary of Effective Date] and [insert date which is
     twelve-month anniversary of Effective Date] of each year, the immediately
     preceding [insert date which is fifteen days after five-month anniversary
     of Effective Date] and [insert date which is fifteen days after
     eleven-month anniversary of Effective Date].

     (4) Voting Rights. The holders of PIK Preferred Stock shall not be entitled
to any voting rights except as hereinafter provided in this Section 4 or in
Section 5 hereof or as otherwise provided by law.

          (a) If and whenever: (i) three dividends on the PIK Preferred Stock
     have not been paid in full; (ii) any bankruptcy, insolvency, arrangement,
     reorganization, receivership or similar proceedings under any federal or
     state law shall be commenced by or against the Company and, in the case of
     any such involuntary proceeding, such proceeding remains undismissed or
     unstayed for sixty (60) days following the commencement thereof, or the
     Company shall take any corporate action authorizing any such proceedings;
     (iii) if, for any reason (including the reason that funds are not legally
     available for a redemption), the Company shall have failed to discharge its
     scheduled redemption obligation on the Scheduled Redemption Date pursuant
     to Section 8(a) hereof or shall have failed to discharge its redemption
     obligation based on the occurrence of a Change of Control pursuant to
     Section 8(c) hereof; or (iv) the Company shall have failed to comply in any
     material respect with any of the covenants set forth in Section 5 or 6
     hereof and such noncompliance shall continue for a period of thirty (30)
     days (any such event referred to in clauses (i), (ii), (iii) or (iv) above
     being hereinafter referred to as a "Triggering Event"), the number of
     directors then constituting the Board shall be increased by two, and the
     holders of PIK Preferred Stock then outstanding shall be entitled to elect
     two additional directors to serve on the entire Board at any annual meeting
     of the stockholders or special meeting held in place thereof; provided,
     however, that if (A) the Liquidation Preference of the outstanding PIK
     Preferred Stock as of the date of the Triggering Event is 50% or less of
     the aggregate Liquidation Preference of PIK Preferred Stock issued to that
     date, including as pay-in-kind dividends on the PIK Preferred Stock, or (B)
     the amount of outstanding Liquidation Preference of PIK Preferred Stock as
     of the date of the Triggering Event shall thereafter be reduced by 50% or
     more, from the time after which the holders of the PIK Preferred Stock
     first have the right hereunder to elect directors, the right to elect such
     additional directors shall be reduced to the right to elect one
                                       G-2
<PAGE>   179

     additional director. In any case, such election shall occur ninety (90)
     days after one of the Triggering Events has occurred if such Triggering
     Event has not then been cured; provided, however, that once such Triggering
     Event has been cured, the right to elect such additional directors or
     director, as the case may be, shall automatically cease (but subject always
     to the same provisions for the vesting of such voting rights in the case of
     the occurrence of any subsequent Triggering Event) and the term of office
     of one director elected pursuant to such election shall forthwith terminate
     and the size of the entire Board shall be reduced accordingly. At any time
     after such voting power shall have been so vested in the holders of PIK
     Preferred Stock, the secretary of the Company (the "Secretary") may, and
     upon the written request of any holder of PIK Preferred Stock (addressed to
     the Secretary at the principal office of the Company) shall, call a special
     meeting of the holders of the PIK Preferred Stock for the election of the
     directors or director, as the case may be, to be elected by them as herein
     provided, such call to be made by notice similar to that provided in the
     Amended and Restated Certificate of incorporation or by-laws of the Company
     for a special meeting of the stockholders or as required by law. If any
     such special meeting required to be called as above provided shall not be
     called by the Secretary within 20 days after receipt of any such request,
     then any holder of PIK Preferred Stock may call such meeting, by providing
     notice thereof, and for that purpose shall have access to the stock-record
     books of the Company. The directors or director, as the case may be,
     elected at any such special meeting shall hold office until the next annual
     meeting of the stockholders or special meeting held in lieu thereof, if
     such office shall not have been terminated as provided above. If any
     vacancy shall occur among the directors or director, as the case may be,
     elected by the holders of PIK Preferred Stock or the successor of such
     remaining directors or director, as the case may be, the remaining director
     elected by the holders of a majority of the outstanding shares of PIK
     Preferred Stock or, if there is no such director, the holders of a majority
     of the outstanding shares of PIK Preferred Stock shall be entitled to fill
     such vacancy, and any person entitled shall serve until the next annual
     meeting of the stockholders or special meeting held in place thereof if
     such office shall not have previously terminated as provided above. Except
     for cause, directors appointed by the holders of the PIK Preferred Stock
     may only be removed by the holders of a majority of the outstanding shares
     of PIK Preferred Stock as set forth in the following sentence. Holders of a
     majority of the outstanding shares of PIK Preferred Stock may remove
     Directors that have been elected on their behalf with or without cause.

          (b) So long as any shares of PIK Preferred Stock remain outstanding,
     without the written consent of the holders of a majority of the outstanding
     shares of PIK Preferred Stock or the approval of holders of a majority of
     the outstanding shares of PIK Preferred Stock at a meeting of such holders
     called for such purpose, the Company shall not amend, alter or repeal any
     provision of the Amended and Restated Certificate of Incorporation of the
     Company including, without limitation, this Annex A relating to the PIK
     Preferred Stock (by merger or otherwise) so as to adversely affect the
     specified preferences, rights, privileges, powers or voting rights of the
     PIK Preferred Stock; provided, however, that any such amendment that
     reduces the dividend payable on or the Liquidation Preference of the PIK
     Preferred Stock shall require the approval of each holder of PIK Preferred
     Stock adversely affected thereby. So long as any shares of PIK Preferred
     Stock remain outstanding, without the written consent of the holders of a
     majority of the outstanding shares of PIK Preferred Stock or the approval
     of holders of a majority of the outstanding shares of PIK Preferred Stock
     at a meeting of such holders called for such purpose, the Company shall
     not, except with respect to such liquidation preference or stated amount of
     shares of any class of capital stock or series of preferred stock of the
     Company or any of its direct or indirect subsidiaries (including any
     pay-in-kind dividends paid thereon) as shall be issued in lieu of up to
     $600,000,000 of initial proceeds from the sale of debt securities as part
     of the Permanent Debt Financing and the first refinancing (if any) of the
     Permanent Debt Financing: (i) create, authorize or issue any Senior
     Securities, or increase the authorized number of shares of any such class
     or series, or reclassify any authorized stock of the Company into any
     Senior Securities or create, authorize or issue any obligation or security
     convertible into or evidencing the right to purchase any Senior Securities;
     (ii) issue any Parity Securities, directly or indirectly, to any Affiliate
     of the Company or its officers or directors; (iii) issue any Parity
     Securities

                                       G-3
<PAGE>   180

     so long as Manville Personal Injury Settlement Trust holds a majority of
     the outstanding shares of PIK Preferred Stock; provided, however, that no
     such consent or approval of the holders of PIK Preferred Stock shall be
     required with respect to the issuance of any shares of Parity Securities
     (the "Basket Parity Securities") otherwise in compliance with this Section
     4(b) (A) having an initial liquidation preference (excluding pay-in-kind
     dividends) not exceeding $150,000,000 in the aggregate at any time
     outstanding and (B) on which the Company shall not, either on a mandatory
     basis or at its option, pay any dividends in cash or other property (other
     than payment in equity securities of the Company that may be issued in
     compliance with this Section 4(b)) unless the Company is then paying
     semi-annual cash (rather than pay-in-kind) dividends on the PIK Preferred
     Stock; or (iv) issue any capital stock with a scheduled redemption date
     prior to the Scheduled Redemption Date (as hereinafter defined) or redeem,
     repurchase, pay dividends or make other distributions in cash or other
     property on capital stock following the Scheduled Redemption Date if the
     PIK Preferred Stock has not been redeemed in full. Except as set forth
     above in this Section 4(b) or in Section 5 hereof, (x) the creation,
     authorization or issuance of any Junior Securities or any Parity
     Securities, (y) a decrease in the amount of authorized capital stock of any
     class, including any preferred stock (other than as set forth in Section 1
     hereof), or (z) an increase in the amount of authorized capital stock of
     any class of Junior Securities or Parity Securities shall not require the
     consent of the holders of PIK Preferred Stock and shall be deemed not to
     affect adversely the specified preferences, rights, privileges, powers or
     voting rights of holders of PIK Preferred Stock.

          (c) In exercising the voting rights set forth in this Section 4 or in
     Section 5 hereof, each share of PIK Preferred Stock shall have one vote per
     share. Except as otherwise required by applicable law or as set forth
     herein, the shares of PIK Preferred Stock shall not have any relative,
     participating, optional or other special voting rights and powers and the
     consent of the holders thereof shall not be required for the taking of any
     corporate action.

     (5) Certain Restrictions. Except with respect to such liquidation
preference or stated amount of shares of any class of capital stock or series of
preferred stock of the Company or any of its direct or indirect subsidiaries
(including any pay-in-kind dividends paid thereon) as shall be issued in lieu of
up to $600,000,000 of initial proceeds from the sale of debt securities as part
of the Permanent Debt Financing and the first refinancing (if any) of the
Permanent Debt Financing, so long as any shares of PIK Preferred Stock remain
outstanding, without the written consent of the holders of a majority of the
outstanding shares of PIK Preferred Stock or the approval of holders of a
majority of the outstanding shares of PIK Preferred Stock at a meeting of such
holders called for such purpose:

          (a) the Company shall not:

             (i) declare or pay dividends on, or make any other distributions
        on, any shares of Junior Securities (other than dividends payable solely
        in Junior Securities of the same class and/or a different class);

             (ii) declare or pay dividends on or make any other distributions on
        any Parity Securities, except: (A) dividends paid on Basket Parity
        Securities in accordance with the proviso to Section 4(b)(iii) hereof;
        provided, however, that after the seventh anniversary of the Effective
        Date, no cash dividends shall be paid by the Company on Basket Parity
        Securities at any time when there shall be any unpaid cash dividends due
        on the PIK Preferred Stock; and (B) dividends paid ratably on shares of
        the PIK Preferred Stock and all other Parity Securities on which
        dividends are payable or in arrears in proportion to the total amounts
        to which the holders of all such shares are then entitled;

             (iii) redeem, purchase, repurchase or otherwise acquire for value
        any Junior Securities; provided, however, that the Company may at any
        time redeem, purchase, repurchase or otherwise acquire shares of any
        such Junior Securities (A) in exchange for shares of any Junior
        Securities or (B) utilizing cash in an amount not greater than the
        proceeds of any offering by the Company of Junior Securities effected
        substantially contemporaneously with the applicable redemption,
        purchase, repurchase or other acquisition; or
                                       G-4
<PAGE>   181

             (iv) redeem, purchase, repurchase or otherwise acquire for value
        any Parity Securities except in accordance with a purchase offer made in
        writing or by publication (as determined by the Board) to all holders of
        such shares (including shares of the PIK Preferred Stock) upon such
        terms as the Board, after consideration of the respective annual
        dividend rates and other relative rights and preferences of the
        respective series and classes, shall determine in good faith will result
        in fair and equitable treatment among the respective series or classes.

          (b) The Company shall not permit any direct or indirect subsidiary of
     the Company to purchase or otherwise acquire for value any shares of the
     capital stock of the Company unless the Company could, under paragraph (a)
     of this Section 5, purchase or otherwise acquire such shares at such time
     and in such manner.

          (c) The Company shall not permit any direct or indirect subsidiary of
     the Company to (i) redeem, purchase, repurchase or otherwise acquire for
     value any equity securities of any direct or indirect subsidiary of the
     Company; provided, however, that any such subsidiary may acquire any such
     equity securities (A) in exchange for any equity securities of the Company
     or any equity securities of any of its direct or indirect subsidiaries that
     may be issued in compliance with Section 4(b) hereof and this Section 5 or
     (B) utilizing cash in an amount not greater than the proceeds of any
     offering by the Company or any of its direct or indirect subsidiaries of
     equity securities effected substantially contemporaneously with the
     applicable redemption, purchase, repurchase or other acquisition; or (ii)
     issue any equity securities to any Person; provided, however, that any such
     subsidiary may issue, to any Person that is not an Affiliate of the Company
     or its officers or directors, equity securities which do not by their terms
     provide for (A) the payment of dividends or other distributions in cash or
     other property (other than payments in equity securities that may be issued
     in compliance with Section 4(b) hereof and this Section 5) or (B) the
     mandatory redemption, on a date when any shares of the PIK Preferred Stock
     remain outstanding, of such equity securities for cash or other property
     (other than redemption payments in equity securities that may be issued in
     compliance with Section 4(b) hereof and this Section 5); or (iii) pay any
     dividend or other distribution on any equity securities in cash or other
     property (other than payments in equity securities that may be issued in
     compliance with Section 4(b) hereof and this Section 5); provided, however,
     that none of the restrictions set forth in this Section 5(c) shall apply to
     any redemption, purchase, repurchase or other acquisition of equity
     securities from, or any issuance of equity securities to, or the payment of
     any dividend or other distribution to, the Company or any of its direct or
     indirect wholly owned subsidiaries.

          (d) The Company shall not allow any encumbrance or restrictions on the
     ability of any of its direct or indirect wholly-owned subsidiaries to: (1)
     pay dividends, in cash or otherwise, or make any other distributions on or
     in respect of its capital stock to the Company or any other subsidiary; (2)
     make loans or advances to the Company or any other subsidiary; or (3)
     transfer any of its properties or assets to the Company or any other
     subsidiary, except for such encumbrances or restrictions imposed under or
     by reason of:

             (i) applicable law;

             (ii) this Annex A relating to the PIK Preferred Stock;

             (iii) customary non-assignment provisions of any lease governing a
        leasehold interest of the Company or any subsidiary;

             (iv) any instrument governing Acquired Indebtedness (as hereinafter
        defined) or Acquired Preferred Stock (as hereinafter defined), which
        encumbrance or restriction is not applicable to any Person (as
        hereinafter defined), or the properties or assets of any Person, other
        than the Person, or the property or assets of the Person, so acquired;

             (v) any agreements of the Company or its subsidiaries existing on
        the date hereof as such agreements are from time to time in effect;
        provided, however, that any amendments or modifications of such
        agreements that affect the encumbrances or restrictions of the types
        subject
                                       G-5
<PAGE>   182

        to this covenant shall not result in such encumbrances or restrictions
        being less favorable to the Company in any material respect, as
        determined in good faith by the Board, than the provision as in effect
        before giving effect to the respective amendment or modification;

             (vi) any restriction with respect to such a subsidiary imposed
        pursuant to an agreement entered into for the sale or disposition of all
        or substantially all the capital stock or assets of such subsidiary
        pending the closing of such sale or disposition;

             (vii) an agreement effecting a refinancing, replacement,
        substitution or restructuring of indebtedness issued, assumed or
        incurred pursuant to an agreement referred to in clause (iv) or (v) in
        this Section 5(d); provided, however, that the provisions relating to
        such encumbrance or restriction contained in any such refinancing,
        replacement, substitution or restructuring agreement or any such other
        agreement are no less favorable to the Company in any material respect
        as determined in good faith by the Board than the provisions relating to
        such encumbrance or restriction contained in agreements referred to in
        such clause (iv) or (v);

             (viii) restrictions on the transfer of assets subject to any lien
        imposed by the holder of such lien;

             (ix) any licensing agreement to the extent such restrictions or
        encumbrances limit the transfer of property subject to such licensing
        agreement;

             (x) restrictions relating to preferred stock issued by a subsidiary
        of the Company in compliance with Section 5(c)(ii) hereof that requires
        due and payable pay-in-kind dividends (or dividends of equity securities
        that otherwise are issued in compliance with Section 5(c)(ii) hereof and
        this Section 5(d)(x)) thereon to be paid in full prior to the payment of
        dividends on such subsidiary's common stock; or

             (xi) any agreement or instrument evidencing indebtedness of the
        Company or any of its subsidiaries including, without limitation, the
        Bridge Loan (as hereinafter defined) (if any) and the Permanent Debt
        Financing.

          (e) The Company shall not, and shall not permit any of its
     subsidiaries to, make any payment to, or sell, lease, transfer or otherwise
     dispose of any of its properties or assets to, or purchase any property or
     assets from, or enter into or make or amend any transaction, contract,
     agreement, understanding, loan, advance or guarantee with, or for the
     benefit of, any Affiliate (as hereinafter defined) of the Company (each of
     the foregoing, an "Affiliate Transaction"), unless such Affiliate
     Transaction shall have been approved by a majority of the members of the
     Board; provided, however, that if such Affiliate Transaction or series of
     related Affiliate Transactions involve aggregate consideration in excess of

exchange or transfer (for cash, shares of stock, securities or other
consideration) of all or substantially all of the property or assets of the
Company nor the consolidation or merger of the Company with or into one or more
corporations shall be deemed to be a liquidation, dissolution or winding-up of
the affairs of the Company (unless such sale, conveyance, exchange or transfer
is in connection with a dissolution or winding up of the business of the
Company).

          (c) Redemption in the Event of a Change in Control. In the event of a
     Change in Control (as hereinafter defined), the Company shall send a notice
     of the occurrence of such Change in Control (the "Notice of Occurrence"),
     by first class mail, postage prepaid, not more than thirty (30) days
     following the occurrence of such Change in Control, to each record holder
     of outstanding shares of PIK Preferred Stock. Such Notice of Occurrence
     shall specify (i) that a Change in Control has occurred; (ii) that such
     holder has the right to require the Company to redeem its outstanding
     shares of PIK Preferred Stock, but only on the terms and subject to the
     conditions set forth in this Section 8(c); (iii) the date, not less than
     thirty (30) days after date of the Notice of Occurrence, by which such
     holder must notify the Company of such holder's intent to exercise such
     redemption right; (iv) that the redemption price shall be 101% of the
     Liquidation Preference of the PIK Preferred Stock, in cash, plus accrued
     and unpaid dividends and distributions thereon, whether or not declared and
     including for any partial semi-annual period, to the date of redemption;
     and (v) that dividends on the shares the holder elects to require the
     Company to redeem will cease to accrue on such date of redemption. Upon
     receipt of such Notice of Occurrence, any holder of PIK Preferred Stock
     may, within the time period specified by the Company, notify the Company,
     by first class mail, postage prepaid, as to whether such holder elects to
     exercise the redemption right. If the holders of a majority

<PAGE>   184

     of the outstanding shares of PIK Preferred Stock elect to require such
     redemption, the Company shall, subject to the extent that it has funds
     legally available therefor, redeem all of the outstanding shares of PIK
     Preferred Stock at such redemption price within sixty (60) days of
     receiving such majority election in accordance with the procedures set
     forth in Section 8(e) hereof. If the holders of less than a majority of the
     outstanding shares of PIK Preferred Stock elect to require such redemption,
     no shares of PIK Preferred Stock shall be redeemed as a result of the
     occurrence of such Change in Control. For purposes of this Section 8(c), a

     right to receive the redemption price specified in Sections 8(a), 8(b) and
     8(c) hereof, as the case may be, without interest, plus accrued and unpaid
     dividends and distributions thereon, whether or not declared and including
     for any partial semi-annual period, to the date of redemption.

          (e) Notice of Redemption, etc. Except as otherwise provided herein,
     the Company shall (i) mail written notice of each redemption of any PIK
     Preferred Stock, by first class mail, postage prepaid, to each record
     holder thereof not more than sixty (60) nor less than thirty (30) days
     prior to the date on which such redemption is to be made and (ii) pay the
     amount specified in Section 8(a), 8(b) or 8(c) hereof, as the case may be,
     to the applicable holder of PIK Preferred Stock, against delivery by such
     holder to the Company of those certificates representing PIK Preferred
     Stock held by such holder which have then been so redeemed. In case fewer
     than the total number of shares of PIK Preferred Stock represented by any
     certificate are redeemed, a new certificate representing the number of
     unredeemed shares of PIK Preferred Stock shall be issued to the holder
     thereof without cost to such holder within five (5) Business Days (as
     hereinafter defined) after surrender of the certificate representing the
     redeemed shares of PIK Preferred Stock.

     (9) Reports. So long as any shares of the PIK Preferred Stock are
outstanding, the Company shall furnish each holder thereof by first class mail,
postage prepaid, at such holder's address as the same appears on the stock
register of the Company, with (a) the annual financial reports that the Company

                                    PART II

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Article IV of Johns Manville's amended and restated by-laws provides that
Johns Manville will indemnify any person who was or is a party or is threatened
to be made a party to any criminal, administrative or investigative action
(other than an action by or in the right of Johns Manville) by reason of the
fact that he is or was a director, officer, employee or agent of Johns Manville,
or is or was serving at the request of Johns Manville as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise, against expenses (including attorneys' fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by him in
connection with such action, suit or proceeding if he acted in good faith and in
a manner he reasonably believed to be in or not opposed to the best interests of
Johns Manville, and with respect to any criminal action or proceeding, if such
person had no reasonable cause to believe his conduct was unlawful. The
termination of any action, suit or proceeding by judgment, order, settlement,
conviction or upon a plea of nolo contendere or its equivalent, shall not, of
itself, create a presumption that the person did not act in good faith and in a
manner which he reasonably believed to be in or not opposed to the best
interests of Johns Manville, and, with respect to any criminal action or
proceeding, had reasonable cause to believe that his conduct was unlawful.

     The Johns Manville by-laws further state that Johns Manville will indemnify
any person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of Johns
Manville to procure a judgment in its favor by reason of the fact that he is or
was a director, officer, employee or agent of Johns Manville.

     Any indemnification will be made by Johns Manville only as authorized by
(a) the Johns Manville Board of directors by a majority vote of a quorum
consisting of directors who were not parties to such action, or (b) if such a
quorum is not obtainable, or even if obtainable a quorum of disinterested
directors so directs, by independent legal counsel in a written opinion, or (c)
by the stockholders.

     Such an indemnification will not be deemed exclusive of any other right
which any person may have or may thereafter acquire, and will continue as to a
person who has ceased to be a director or officer of Johns Manville, or a
director, officer, employee or agent of any other enterprise and will inure to
the benefit of the heirs, executives and administrators of such a person.

     Section 145 of the Delaware General Corporation Law permits a corporation
to indemnify its directors and officers against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by them in connection with any action, suit or proceeding brought by
third parties, if such directors of officers acted in good faith and in a manner
they reasonably believed to be in or not opposed to the best interests of the
corporation and, with respect to any criminal action or proceeding, had no
reasonable cause to believe their conduct was unlawful. In a derivative action,
i.e., one by or in the right of the corporation, indemnification may be made
only for expenses actually and reasonably incurred by directors and officers in
connection with the defense or settlement of an action or suit, and only with
respect to a matter as to which they have acted in good faith and in a manner
they reasonably believed to be in or not opposed to the best interests of the
corporation, except that no indemnification will be made if such person will
have been adjudged liable to the corporation, unless and only to the extent that
the court in which the action or suit was brought will determine upon
application that the defendant officers or directors are fairly and reasonably
entitled to indemnity for such expenses despite such adjudication of liability.

     Article IV of the Johns Manville by-laws states that Johns Manville will
have a power to purchase and maintain insurance on behalf of any person who is
or was a director, officer, employee or agent of the corporation against any
liability asserted against him and incurred by him in any such capacity, or
arising out of his status as such, whether or not Johns Manville would have the
power to indemnify him against such liability under the provisions of Article
IV.

                                      II-1

     The merger agreement contains provisions by which the surviving corporation
agrees to indemnify directors, officers, employees and agents of Johns Manville
to the fullest extent permitted by law at all times after the merger for any
claim based on actions taken prior to the consummation of the merger and will
maintain directors' and officers' liability insurance for a period of six years
for such actions (limited by annual cost cap of 200% of the current premium),
and for six years after the merger, indemnity provisions in the surviving
corporation's charter and by-laws will be maintained.

     Whether or not the merger occurs, the surviving corporation will indemnify
all current and prior employees, agents, directors or officers of HB Merger LLC
and HB Finance LLC for any claim that is primarily based on an allegation that
HB Merger LLC, HB Finance LLC or their affiliates has induced or acted in
concert with Johns Manville or its directors to act contrary to or in violation
of any contract, duty or applicable law to which Johns Manville and the
directors are subject.

ITEM 22. UNDERTAKINGS

     (a) The undersigned registrant hereby undertakes:

          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement:

             (i) To include any prospectus required by Section 10 (a) (3) of the
        Securities Act of 1933;

             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of the registration statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the registration statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424 (b) if, in the aggregate, the
        changes in volume and price represent no more than 20 percent change in
        the maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective registration statement.

             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the registration statement
        or any material change to such information in the registration
        statement.

          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bone fide offering thereof.

          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.

     (b) The undersigned registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent or
given, the latest annual report, to security holder that is incorporated by
reference in the prospectus and furnished pursuant and meeting the requirement
of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of 1934; and,
where interim financial information required to be presented by Article 3 of
Regulation S-X is not set forth in the prospectus, to deliver, or cause to be
delivered to each person to whom the prospectus is sent or given, the latest
quarterly report that is specifically incorporated by reference in the
prospectus to provide such interim financial information.

     (c) The undersigned registrant hereby undertakes as follows: that prior to
any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145 (c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.

     (d) The registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (1) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a) (3) of the Act and is used in connection with
an offering of securities subject to Rule 415, will be filed as a part of an
amendment to the registration statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

     (e) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing
                                      II-7
<PAGE>   196

provisions, or otherwise, the registrant has been advised that in the opinion of
the Securities and Exchange Commission such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the registrant of expenses incurred or paid by a director, officer or
controlling person in the successful defense of any action, suit or proceeding)
is asserted by such director, officer or controlling person in connection with
the securities being registered, the registrant will, unless in the opinion of
its counsel the matter has been settled by controlling precedent, submit to a
court of appropriate jurisdiction the question whether such indemnification by
it is against public policy as expressed in the Act and will be governed by the
final adjudication of such issue.

     (f) The undersigned registrant hereby undertakes that:

          (1) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this registration statement in reliance upon Rule 430A and contained in
     a form of prospectus filed by the registrant pursuant to Rule 424 (b) (1)
     or (4) or 497 (h) under the Securities Act shall be deemed to be part of
     this registration statement as of the time it was declared effective.

          (2) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.

     (g) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10 (b), 11, or 13 or this form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

     (h) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.
