                  (a)      Each issued and outstanding share of Company Common

Any payment made pursuant to this Section 2.1(a) shall be made net of applicable
withholding taxes to the extent such withholding is required by law.

                  (b)      Each issued and outstanding share of Class TM

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

Consideration for each share of Class TM Preferred Stock upon the surrender of

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

                  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)

                                       4
<PAGE>   13
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 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

                                       5
<PAGE>   14
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 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

                                       6
<PAGE>   15
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

                                       7
<PAGE>   16
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
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

                                       8
<PAGE>   17
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
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).

to do business as a foreign corporation and is in good standing in each
jurisdiction in which the nature of the business conducted by it makes such
qualification or licensing necessary, except where the failure to be so
organized, existing and in good standing or to have such power and authority, or
to be so qualified or licensed would not have 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 its Restated Certificate of
Incorporation and by-laws, as currently in effect (the "By-Laws").

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

relating thereto and (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.

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

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

5.4(c)), (ii) with respect to the issuance of Surviving Corporation Common
Stock, Surviving Corporation Preferred Stock and Surviving Corporation Junior

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

                                       12
<PAGE>   21

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.

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
securities of the Company or its Subsidiaries or guaranteed any material
indebtedness for money borrowed other than under credit facilities in the
ordinary course of business and other than borrowings in the ordinary course of
business that can be repaid at any time without prepayment penalty or other
similar fees;

                  (c)      granted any material increase in the fringe benefits
or compensation payable or to become payable by the Company to any officer or

                  (d)      entered into any significant new line of business
outside of the buildings products industry, or incurred or committed to any

<PAGE>   22
expenditures and obligations or liabilities incurred or committed to that are no
greater than the amount designated therefor in the Company's current capital
budget approved by the Board in December, 1999, the amount of which has been
furnished to Merger Company prior to the date hereof (the "Capital Budget");

                  (e)      other than in the ordinary course of business
consistent with past practice, sold, leased, mortgaged, encumbered or otherwise
disposed of, any material assets (including capital stock of Subsidiaries);

                  (f)      merged or consolidated with, or purchased an equity
interest in all or substantially all of the assets (which assets shall be
material to the Company) of, any Person or other business organization or any
division or business thereof; or

                  (g)      agreed to take any of the foregoing actions
identified in subparagraphs (a) through (f) above.

                  Section 3.7 Absence of Undisclosed Liabilities. Except as
expressly identified in the Company SEC Documents, or as reflected or reserved
against in the balance sheet dated as of December 31, 1999 or the balance sheet
dated as of March 31, 2000 constituting a portion of the financial statements
included in the Company's Annual Report on Form 10-K for the term ended December

(the "Balance Sheets") or in the notes thereto and except for liabilities in
respect of Litigation (which are the subject of Section 3.10) and liabilities
under Environmental Laws (which are the subject of Section 3.15), neither the
Company nor any of its Subsidiaries had as of that date any liabilities which
were material to the Company and its Subsidiaries taken as a whole and which
were required to be set forth in the Balance Sheets or the notes thereto in
accordance with GAAP. Except as disclosed in the Company SEC Documents, since
the date of the Balance Sheet, the Company has not incurred any liabilities that
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 would not have a Material Adverse Effect,
liabilities resulting from the execution and delivery of this Agreement or
relating to the transactions contemplated hereby and except for liabilities in
respect of Litigation (which are the subject of Section 3.10) and liabilities
under Environmental Laws (which are the subject of Section 3.15).

                  Section 3.8 Information in Disclosure Documents. None of (i)

in connection with the issuance of Surviving Corporation Preferred Stock as

(iii) any information to be supplied by the Company in any other statement or
schedule required to be filed by either the Company or the Merger Company with
the SEC in connection with the transaction contemplated hereby will contain, at
the date mailed to Company stockholders and at the time of the Special Meeting
(as defined in Section 5.6(a)), any untrue statement of a material fact or omit
to state any material fact required to be stated

                                       14
<PAGE>   23
therein or necessary in order to make the statements therein, in light of the
circumstances under which they are made, not misleading and the S-4, the Proxy
Statement and any other statement or schedule filed by the Company will comply
in all material respects with the applicable provisions of the Exchange Act and
the rules and regulations thereunder; except that no representation is made by
the Company with respect to statements made in the S-4, the Proxy Statement or
such statement or schedule based on information supplied by Merger Company for
inclusion in the S-4 or the Proxy Statement.

                  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")

                                       15
<PAGE>   24
         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
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

                                       16
<PAGE>   25
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 would reasonably be expected to result in a liability greater
than $5,000,000, 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 law, statute, regulation, judgment, decree, order
or injunction of any Governmental Entity, except where such violations would not
have a Material Adverse Effect.


                                       17
<PAGE>   26

         (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 Section 3.15) and except where the failure to hold such licenses,
permits, variances or approvals would not have a Material Adverse Effect.

         (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
Subsidiaries own free and clear of any Lien, other than Permitted Exceptions, or
possess licenses or other valid rights to use, all patents, patent rights,
domain names, trademarks (registered or unregistered), trade dress, trade names,
copyrights (registered or unregistered), service marks, trade secrets, know-how
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
except where such infringement would not reasonably be expected to create a
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

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



                                       37
<PAGE>   46
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



                                       38
<PAGE>   47
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,
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



                                       39
<PAGE>   48
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.



                                       40
<PAGE>   49
         (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 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




                                       41
<PAGE>   50
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
Meeting") as promptly as reasonably practicable after the date hereof for the
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 and a preliminary proxy statement and the parties shall file, if
necessary, any 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 Statement (as hereinafter defined) and any such statement
or schedule. After 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 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



                                       42
<PAGE>   51
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,




                                       43
<PAGE>   52
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 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



                                       44
<PAGE>   53
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.

         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



                                       45
<PAGE>   54
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

                           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,

                           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

                           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

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 Day period after the Company's notice, the Company

<PAGE>   61
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 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

that it will not enter into a binding agreement referred to in clause (ii) above
until at least five Business Days after it has provided the notice to Merger
Company required by the first sentence of this Section 7.1(c) and has made the
payments required by the immediately preceding sentence and (y) to notify Merger
Company promptly if the Board determines not to enter into a binding agreement
with respect to the Superior Proposal as to which notification was given.

as required by Section 5.2 or (z) the commencement of negotiations with such
third party or (iv) the Special Meeting has not been held on or prior to January
15, 2001, unless Merger Company has materially contributed to the failure to
hold such meeting or the Company has been restrained, enjoined or otherwise
prohibited by a 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 after the expiration of any applicable period following such
notice. In the 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,

is intended to or shall confer upon any other person any rights, benefits or
remedies of any nature whatsoever under or by reason of this Agreement. Without
limiting the foregoing, except with respect to the obligations of the Trust
under the Trust Voting Agreement, no direct or indirect holder of any equity
interests or securities of either party hereto (whether such holder is a limited
or general partner, member, stockholder or otherwise), nor any affiliate of any

other controlling person of each of the parties hereto and their respective
affiliates shall have any liability or obligation arising under this Agreement

other authority to be invalid, void, unenforceable or against its regulatory
policy, the remainder of the terms, provisions, covenants and restrictions of
this Agreement shall remain in full force and effect and shall in no way be
affected, impaired or invalidated.

giving effect to the principles of conflicts of law thereof.

                  Section  8.12 Assignment. Neither this Agreement nor any of
the rights, interests or obligations hereunder shall be assigned by any of the
parties hereto (whether by operation of law or otherwise) without the prior
written consent of the other parties; provided, however, that each of Merger
Company and Finance Company shall be permitted to assign its rights under this
Agreement to any newly formed wholly-owned subsidiaries of the members thereof
and provided further that any such assignment will not relieve such party of its
obligations hereunder. Subject to the preceding sentence, this Agreement will be
binding upon, inure to the benefit of and be enforceable by, the parties and
their respective successors and assigns, and except to the extent necessary to
enforce the provisions of Section 5.7, 5.11 and 8.9, the provisions of this
Agreement are not intended to confer upon any person other than the parties
hereto any rights or remedies hereunder.

hereto, which consent shall not be unreasonably withheld. The parties agree that
the initial press release to be issued with respect to the transactions
contemplated by this Agreement shall be in the form heretofore agreed to by the
parties.

                  Section  8.14 Enforcement. The parties agree that irreparable
damage would occur in the event that any of the provisions of this Agreement
were not performed in accordance with their specific terms or were otherwise
breached. It is accordingly agreed that the parties shall be entitled to an
injunction or injunctions to prevent breaches of this Agreement and to enforce
specifically the terms and provisions of this Agreement in any Federal court
located in the State of Delaware or in any Delaware state court, this being in
addition to any other remedy to which they are entitled at law or in equity. In
addition, each of the parties hereto (a) consents to submit itself to the
personal jurisdiction of any Federal court located in the State of Delaware or
any Delaware state court in the event any dispute arises, out of this Agreement
or any of the transactions contemplated by this Agreement and (b) agrees that it
will not attempt to deny or defeat such personal jurisdiction by motion or other
request for leave from any such court and (c) agrees that such forum is not an
inconvenient forum.

                           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
<PAGE>   72
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.

                  (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

                                      A-2
<PAGE>   73
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 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

                                      A-3
<PAGE>   74
         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. "Business Day" means any day except a Saturday, Sunday or
         other day on which commercial banks in the State of Delaware or the
         State of New York are authorized by law to close.

         B.       Provisions Relating to Common Stock. The rights, preferences,
privileges, restrictions and other matters relating to the Common Stock are as
follows:

                  No holder of Common Stock of the Company shall be entitled as
of right to purchase or subscribe for any part of the unissued stock of the
Company or of any stock of the Company to be issued by reason of any increase of
the authorized capital stock of the Company or of the number of its shares, or
of bonds, certificates of indebtedness, debentures, or other securities
convertible into stock of the Company or of any stock of the Company purchased
by it or its nominee or nominees.

                  The holders of the Common Stock shall have the right to one
vote per share on all questions to the exclusion of all other classes or classes
of stock, except as by law expressly provided or as otherwise herein expressly
provided with respect to the holders of any other class or classes of stock."

of the foregoing, the determination of any or all of the following:

                  (5)      The right, if any, of the holders of such series of
Preferred Stock to convert the same into, or exchange the same for, shares of
any other class or series of

Stock will be entitled to one vote on each matter submitted to a vote at a
meeting of stockholders for each share of Common Stock held of record by such
holder as of the record date for such meeting and shall be entitled to all other

                  SIXTH: (a) Except as provided below, no director of the

arising from a breach of any duty. Nothing in this Article Sixth shall eliminate
or limit the liability of any director for any act, omission or transaction or
under any statutory provision if and to the extent that the DGCL does not permit
such elimination or limitation. Neither amendment nor repeal of this paragraph
(a) nor the adoption of any provision of the Certificate of Incorporation
inconsistent with this paragraph (a) in respect of any matter occurring, or any
cause of action, suit or claim that, but for this paragraph (a) of this Article,
would accrue or arise, prior to such amendment, repeal or adoption of an
inconsistent provision.

investigative (including, without limitation, any action, suit or proceeding by
or in the right of the Company or any partnership, corporation, joint venture,
trust or other enterprise with respect to which such person serves or has served
as a director, officer, fiduciary, employee or agent) by reason of the fact that
such person is or was at any time a director, officer, fiduciary, employee or
agent of the Company, including any predecessor thereto or constituent thereof,
or is or was serving at the request of the Company, including any predecessor
thereto or constituent thereof, as a director, officer, fiduciary, employee or

action, suit or proceeding occurred or allegedly occurred, against all expenses
(including attorneys' fees and expenses), judgments, fines and amounts paid in
settlement, whenever paid or payable, to the fullest extent and in the manner
(including by way of advancement of costs and expenses) that a corporation
organized under Delaware law is from time to time permitted to indemnify its
directors, officers, fiduciaries, employees and agents.

                                                                         ANNEX A

               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 the 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,
<PAGE>   81
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
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 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

                                      A-2
<PAGE>   82
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 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

                                      A-3
<PAGE>   83
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

                                      A-4

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 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


                                      A-5
<PAGE>   85
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

               (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

     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

such manner.

          (c)   The Company shall not permit any direct or indirect subsidiary

equity securities of any of its direct or


                                      A-6
<PAGE>   86
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)

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

     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 to this
     covenant

                                      A-7

<PAGE>   87
     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 of the capital stock or assets of such subsidiary pending

               (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

     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;

                                      A-8

<PAGE>   88
provided, however, that if such Affiliate Transaction or series of related
Affiliate Transactions involve aggregate consideration in excess of
$10,000,000, such Affiliate Transaction shall be approved by a majority of the
Board and evidenced in a resolution of the Board certifying that the terms of
such Affiliate Transaction are at least as favorable to the Company or the
relevant subsidiary as might reasonably have been obtained in a comparable
arm's length transaction with an unaffiliated third party; and provided
further, the foregoing restrictions shall not apply to such Affiliate
Transactions as are exempted from any covenant or restriction relating to
transactions between the Company and its Affiliates set forth in the agreements
representing the Bridge Loan, the Permanent Debt Financing and the first
refinancing (if any) of the Permanent Debt Financing.

         (6)  REACQUIRED SHARES. Any shares of PIK Preferred Stock purchased or
otherwise acquired by the Company in any manner whatsoever (including by
redemption or 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 either as PIK Preferred Stock subject to the
limitations hereof or as part of a new series of preferred stock to be created
by resolution or resolutions of the Board or as otherwise permitted under the
DGCL.

         (7)  LIQUIDATION, DISSOLUTION OR WINDING UP. Upon any liquidation,
dissolution or winding up of the Company, no distribution shall be made: (a) to
the holders of Junior Securities unless, prior thereto, the holders of shares
of PIK Preferred Stock shall have received a liquidation preference of $100 per
full share of PIK Preferred Stock (the "Liquidation Preference"), plus an
amount equal to accrued and unpaid dividends and distributions thereon, whether
or not declared and including for any partial semi-annual period, to the date
of payment; or (b) to the holders of Parity Securities, except distributions
made ratably on the PIK Preferred Stock and all other such Parity Securities in
proportion to the total amounts to which the holders of all such shares are
entitled upon such liquidation, dissolution or winding up.

         For purposes of this Section 7 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).

         (8)  REDEMPTION.

              (a)  Scheduled Redemption. Subject to the extent that the Company
has funds legally available therefor, each outstanding share of PIK Preferred
Stock shall be redeemed by the Company on the twelfth anniversary of the

         (b) Redemption at the Option of the Company. All outstanding shares of

Stock), on not less than 30 nor more than 60 days' notice to the holders of the
PIK Preferred Stock at the following prices (expressed as percentages of the
Liquidation Preference) (each such percentage hereinafter referred to as the
"Redemption Price") 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, if redeemed during the following periods as
indicated below:

</TABLE>

         (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 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

                                      A-10
<PAGE>   90
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 "Change in Control" shall be defined as: (i) the acquisition of more
than 50% of the outstanding shares of Common Stock by any one holder other than
the holders of Common Stock immediately following the Merger (each, an "Initial
Holder") or (ii) the acquisition by a Person that is not an Initial Holder or an
Affiliate thereof of a number of shares of Common Stock that is more than the
aggregate number of shares of Common Stock then held by the Initial Holders and
their Affiliates.

     (d)  Status of Redeemed Shares.  At the time of redemption specified in the
resolution of the Board authorizing such redemption, the rights of the holders
of the PIK Preferred Stock redeemed shall cease, except for the 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
is required to file with the Securities and Exchange Commission (the "SEC")
pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934,
as amended (the "Exchange Act"), or (b) in the event that the Company is not
required to file such reports, (i) annual reports containing the same financial
information as would be required in reports so filed and (ii) quarterly
financial reports containing the same financial information as would be required
in quarterly reports filed with the SEC pursuant to Section 13 or 15(d) of the
Exchange Act.

               FORM OF TERMS, PREFERENCES, RIGHTS AND LIMITATIONS

                                       of

                      SERIES B CONVERTIBLE PREFERRED STOCK

                                       of

                           JOHNS MANVILLE CORPORATION




                  The rights, preferences, privileges, restrictions and other
matters relating to the Series B Convertible 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 B Convertible Preferred Stock (the
"Junior Preferred Stock"), and the number of shares constituting the Junior
Preferred Stock shall be 16,000,000. Such number of shares may be increased or
decreased by resolution of the Board of Directors of the Company (the "Board");
provided, however, that no decrease shall reduce the number of shares of Junior
Preferred Stock to a number less than the number of shares then outstanding plus
the number of shares reserved for issuance upon the exercise of outstanding
options, rights or warrants or upon the conversion of any outstanding securities
issued by the Company convertible into Junior Preferred Stock.

                  (2) Rank. The Junior Preferred Stock shall rank, with respect
to distributions upon the liquidation, winding-up and dissolution of the
Company, prior to all classes of common stock, par value $.01 per share, of the
Company (the "Common Stock") and prior 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 Junior
Preferred Stock as to Dividends (as hereinafter defined) and distributions upon
the liquidation, winding-up and dissolution of the Company (the "Junior
Securities"). The Junior Preferred Stock shall rank: (a) with respect to
Dividends, pari passu with the Common Stock; and (b) with respect to Dividends
and distributions upon the liquidation, winding-up and dissolution of the
Company, 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 Junior Preferred Stock as to Dividends and
distributions upon the liquidation, winding-up and dissolution of the Company
(the "Parity Securities"). The Junior Preferred Stock shall rank, with respect
to Dividends and distributions upon the liquidation, winding-up and dissolution
of the Company, junior to the Series A Redeemable PIK Preferred Stock (the "PIK
Preferred Stock") and junior to any class of capital stock or series of
preferred stock hereafter created by the Board, the terms of which expressly
provide that it ranks prior to the Junior Preferred Stock as to Dividends and
distributions upon the liquidation,

<PAGE>   94

winding-up and dissolution of the Company (collectively referred to with the PIK
Preferred Stock as the "Senior Securities").

                  (3) Dividends and Distributions. Subject to the prior and
superior rights of the holders of shares of the Senior Securities, the holders
of shares of Junior Preferred Stock shall be entitled to receive, when, as and
if declared by the Board out of funds legally available therefor, dividends or
distributions in cash, securities or other property (individually a "Dividend"
and collectively "Dividends"), but only when, as and if Dividends are declared
and paid on the Common Stock, payable with respect to each share of Junior
Preferred Stock as if each such 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. Dividends shall not be deemed to include any securities which are
to be taken into account in adjusting the Conversion Ratio (as hereinafter
defined) as set forth in Section 7(d) hereof.

                  (4) Voting Rights. The holders of shares of the Junior
Preferred Stock shall have the following voting rights:

                           (a) Each share of Junior Preferred Stock shall
entitle the holder thereof to vote, on all matters submitted to a vote of the
stockholders of the Company, the number of votes equal to the number of shares
of Common Stock into which such share of the Junior Preferred Stock would be
converted if converted immediately prior to the record date for such vote.
Except as otherwise provided herein or in any Certificate of Designations
creating another series of Senior Securities or Parity Securities, or by law,
the holders of shares of Junior 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.

                           (b) So long as any shares of Junior Preferred Stock
remain outstanding, without the written consent of the holders of at least 85%
of the outstanding shares of Junior Preferred Stock or the approval of holders
of at least 85% of the outstanding shares of Junior 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 B relating to the Junior
Preferred Stock (by merger or otherwise) so as to adversely affect the specified
preferences, rights, privileges, powers or voting rights of the Junior Preferred
Stock; provided, however, that any such amendment that reduces the Liquidation
Preference (as hereinafter defined) of the Junior Preferred Stock shall require
the approval of each holder of Junior Preferred Stock adversely affected
thereby.

                           (c) Except as set forth herein or as required by law,
holders of Junior Preferred Stock shall have no special voting rights and their
consent or vote as a class shall not be required for taking any corporate
action.

                                      B-2
<PAGE>   95

                  (5) Reacquired Shares. Any shares of Junior Preferred Stock
purchased or otherwise acquired by the Company in any manner whatsoever
(including by redemption or 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 either as Junior Preferred Stock or
as part of a new series of preferred stock to be created by resolution or
resolutions of the Board 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 (a) to the holders of shares of Junior Securities (either as to Dividends
or distributions upon liquidation, dissolution or winding up) or the Common
Stock (as to distributions upon liquidation, dissolution or winding up) unless,
prior thereto, the holders of shares of Junior Preferred Stock shall have
received a liquidation preference of $15.625 per share (the "Liquidation
Preference"), or (b) to the holders of Parity Securities (either as to Dividends
or distributions upon liquidation, dissolution or winding up) and Common Stock
(as to Dividends), except distributions made ratably on the Junior Preferred
Stock and all other such Parity Securities or Common Stock, as applicable, in
proportion to the total amounts to which the holders of all such shares are
entitled upon such liquidation, dissolution or winding up.

                  For purposes of this 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) Conversion Rights.

                           (a) Optional Conversion. Each outstanding share of
Junior Preferred Stock shall be converted into, subject to adjustment as set
forth in Section 7(d) hereof, one fully paid and non-assessable share of Common
Stock (such share-for-share conversion ratio, as adjusted from time to time,
being hereinafter referred to as the "Conversion Ratio") if the holders of a
majority of the outstanding shares of Junior Preferred Stock, voting as a class,
approve such conversion; provided, however, that such holders may elect, from
time to time, to require the conversion of less than all of the shares of Junior
Preferred Stock then outstanding, in which case such partial conversion will be
made on an equal basis such that, immediately following such conversion, each
holder of Junior Preferred Stock will hold the same percentage of the issued and
outstanding Junior Preferred Stock as it held immediately prior to such
conversion. Following written notice to the Company of any such election, the
Company shall establish a record date for such conversion (which shall be no
earlier than the date of the Company's receipt of such notice and no later than
20 days after the Company's receipt of such notice) and shall notify each holder
of record (as of such record date), by first


                                      B-3
<PAGE>   96

class mail, postage prepaid, of the full or partial conversion of the Junior
Preferred Stock in accordance with this Section 7(a) and that the issuance of
certificates representing the shares of Common Stock issued as a result of
conversion (and any Junior Preferred Stock remaining outstanding after such
conversion) shall be effected in accordance with the procedures set forth in
Section 7(c) hereof. Failure to give such notice to any such holder shall in no
way affect the full or partial, as applicable, conversion of such Junior
Preferred Stock into Common Stock. The conversion effected pursuant to this
Section 7(a) shall be deemed to have occurred on the record date established as
set forth above and the shares of Junior Preferred Stock converted on such
conversion shall be automatically converted at such time. Immediately following
such conversion, the rights of the holders of converted Junior Preferred Stock
shall cease and the persons entitled to receive the Common Stock upon the
conversion of Junior Preferred Stock shall be treated for all purposes as having
become the owners of such Common Stock.

                           (b) Mandatory Conversion. All outstanding shares of
Junior Preferred Stock shall automatically be converted, at the Conversion
Ratio, into fully paid and non-assessable shares of Common Stock at such time as
the Company consummates a Qualified Initial Public Offering (as hereinafter
defined), in which the aggregate per share offering price is at least $15.625
per share (provided that in the event the Company shall effect any stock
dividend, stock split, reverse stock split or other combination of shares of
common stock, recapitalization, reclassification, merger, consolidation or
exchange offer, or similar events and transactions, then, and in each such case,
such minimum price per share in effect immediately prior to such event or
transaction or the record date therefor, whichever is earlier, shall be
appropriately adjusted as determined in good faith by the Board); provided,
however, that such outstanding shares of Junior Preferred Stock shall not be
converted if, and to the extent that, shares of Junior Preferred Stock shall
have been called for redemption pursuant to Section 8(b) hereof on or prior to
the date of consummation of the Qualified Initial Public Offering; and provided
further that, notwithstanding the immediately preceding proviso, such
unconverted shares of Junior Preferred Stock shall nevertheless automatically be
converted on the date that the applicable redemption payment is due pursuant to
Section 8(e) hereof if and to the extent that such redemption payment shall not
be made. The term "Qualified Initial Public Offering" shall mean one or a series
of firm commitment underwritten public offerings of newly issued Common Stock
pursuant to a registration statement under the Securities Act of 1933, as
amended, where (i) the proceeds to the Company (prior to deducting any
underwriters' discounts and commissions) equal or exceed $100,000,000 and (ii)
upon consummation of such offering, 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. The Company shall notify each record holder of Junior
Preferred Stock, by first class mail, postage prepaid, on the date of
consummation of the Qualified Initial Public Offering, of the mandatory
conversion of all outstanding shares of Junior Preferred Stock in accordance
with this Section 7(b) and that the issuance of certificates representing the
shares of Common Stock issued on conversion thereof shall be effected in
accordance with the procedures set forth in Section 7(c) hereof. Failure to give
such notice to any such holder shall in no way affect the mandatory conversion
of such Junior


                                      B-4
<PAGE>   97

Preferred Stock into Common Stock. Immediately following such conversion, the
rights of the holders of all Junior Preferred Stock shall cease and the persons
entitled to receive the Common Stock upon the conversion of Junior Preferred
Stock shall be treated for all purposes as having become the owners of such
Common Stock.

                 (c) Mechanics; Transfer Tax; Conversion Price.

                                    (i) As soon as practicable after the
         conversion of any shares of Junior Preferred Stock into Common Stock
         under Section 7(a) or 7(b) above, the Company shall deliver to the
         applicable holder of Junior Preferred Stock a certificate for the
         number of shares of Common Stock issuable upon the conversion (and a
         new certificate representing the unconverted portion, if any, of the
         shares of Junior Preferred Stock represented by the certificate or
         certificates surrendered for conversion), against delivery by such
         holder to the Company of those certificates representing Junior
         Preferred Stock held by such holder which have been converted in such
         conversion. The person in whose name the Common Stock certificate is
         registered shall be treated as the stockholder of record on and after
         the Conversion Date. No payment or adjustment shall be made for accrued
         and unpaid Dividends, if any, on converted shares of Junior Preferred
         Stock or for Dividends on any Common Stock issued upon such conversion.
         The holder of record of a share of Junior Preferred Stock at the close
         of business on a record date with respect to the payment of Dividends
         on the Junior Preferred Stock in accordance with Section 3 hereof shall
         be entitled to receive such Dividends with respect to such share of
         Junior Preferred Stock on the corresponding dividend payment date,
         notwithstanding the conversion of such share after such record date and
         prior to such dividend payment date.

                                    (ii) Upon conversion of shares of Junior
         Preferred Stock, the Company shall pay any documentary, stamp or
         similar issue or transfer tax due on the issue of shares of Common
         Stock upon the conversion; provided, however, the holder shall pay any
         such tax that is due because the shares are issued in a name other than
         the holder's name.

                                    (iii) The Company has reserved and shall
         continue to reserve out of its authorized but unissued Common Stock or
         its Common Stock held in treasury sufficient shares of Common Stock to
         permit the conversion, in full, of all of the Junior Preferred Stock to
         Common Stock. All shares of Common Stock that may be issued upon
         conversion of the Junior Preferred Stock shall be fully paid and
         non-assessable.

                 (d) Conversion Ratio Adjustments.

                                    (i) If, at any time after the issuance of
         the Junior Preferred Stock, the outstanding shares of the Common Stock
         shall be increased by a stock dividend payable in shares of Common
         Stock or by a stock split, subdivision or split-up of shares of Common
         Stock, then, following the record


                                      B-5
<PAGE>   98

         date for the determination of holders of Common Stock entitled to
         receive such Common Stock pursuant to such stock dividend, stock split,
         subdivision or split-up, the Conversion Ratio shall be proportionately
         adjusted so that the number of shares of Common Stock issuable upon
         conversion of each share of Junior Preferred Stock shall be increased
         to the number of shares of Common Stock the holder of each such share
         of Junior Preferred Stock would have held after such stock dividend,
         stock split, subdivision or split-up, if such holder had converted each
         such share of Junior Preferred Stock immediately prior thereto, in
         accordance with the provisions hereof.

                                    (ii) If, at any time after the issuance of
         the Junior Preferred Stock, the outstanding shares of Common Stock
         shall be decreased by a combination (including, without limitation, any
         reverse stock split) of the outstanding shares of Common Stock, then,
         following the record date for such combination, the Conversion Ratio
         shall be proportionately adjusted so that the number of shares of
         Common Stock issuable upon conversion of each share of Junior Preferred
         Stock shall be decreased to the number of shares of Common Stock the
         holder of each such share of Junior Preferred Stock would have held
         after such combination, if such holder had converted each such share of
         Junior Preferred Stock immediately prior thereto, in accordance with
         the provisions hereof.

                                    (iii) In the case of any consolidation of
         the Company, the merger of the Company with or into any other entity,
         statutory share exchange or other reorganization or similar transaction
         or the sale or transfer of all or substantially all the assets of the
         Company, in any such case pursuant to which the Common Stock is
         converted into other securities, cash or assets, then, upon
         consummation of such transaction, each share of Junior Preferred Stock
         shall automatically become convertible into the kind or amount of
         securities, cash and other assets receivable upon the consolidation,
         merger, statutory share exchange or other reorganization, sale,
         transfer or similar transaction, by a holder of the number of shares of
         Common Stock into which such share of Junior Preferred Stock would have
         been converted if such share of Junior Preferred Stock was converted
         immediately prior to such consolidation, merger, statutory share
         exchange or other reorganization, sale, transfer or similar transaction
         (assuming such holder of Common Stock failed to exercise any rights of
         election and received per share the kind and amount of consideration
         receivable per share by a plurality of non-electing shares).
         Appropriate adjustment (as determined in good faith by the Board) shall
         be made in the application of the provisions herein set forth with
         respect to the rights and interests thereafter of the holders of Junior
         Preferred Stock, to the end that the provisions set forth herein
         (including provisions with respect to changes in and other adjustment
         of the Conversion Ratio) shall thereafter be applicable, as nearly as
         reasonably possible, in relation to any shares of stock or other
         securities or property thereafter deliverable upon


                                      B-6
<PAGE>   99

         the conversion of Junior Preferred Stock. If this Section 7(d)(iii)
         applies, Sections 7(d)(i) and 7(d)(ii) do not apply.

                                    (iv) If the Company takes any action that
         would require an adjustment in the Conversion Ratio pursuant to Section
         7(d)(i), (ii) or (iii) above, the Company shall mail to the holders of
         Junior Preferred Stock a notice stating the proposed record or
         effective date, as the case may be, and such adjustment shall become
         effective immediately after the record date of the event triggering the
         adjustment. The Company shall mail such notice, by first class mail,
         postage prepaid, at least ten (10) days before such date. However,
         failure to mail the notice or any defect in it shall not affect the
         validity of any such action.

                 (8) Redemption.

                           (a) Scheduled Redemption. Subject to the extent that
the Company has funds legally available therefor, each outstanding share of
Junior Preferred Stock shall be redeemed by the Company on _________, 2021 [the
date which is six months after the twentieth anniversary of the date of
issuance] (the "Scheduled Redemption Date") at the Liquidation Preference
(subject to the right each such record holder to receive Dividends due on a
dividend payment date).

                           (b) Redemption at the Option of the Company. All
outstanding shares of Junior Preferred Stock shall be redeemable at the option
of the Company, at any time as a whole or from time to time in part (any such
partial redemption to be effected pro rata among the holders of outstanding
shares of Junior Preferred Stock), on not less than thirty (30) nor more than
sixty (60) days' notice to the holders of the Junior Preferred Stock at the
Liquidation Preference (subject to the right of each such record holder to
receive Dividends due on a dividend payment date) on the payment date specified
in such notice which date shall not be less than thirty (30) nor more than sixty
(60) days after the date of such notice.

                           (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 Junior Preferred Stock. The 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 outstanding shares of Junior 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; and (iv) that the redemption
price shall be 100% of the Liquidation Preference of the Junior Preferred Stock,
in cash (subject to the right of each such record holder to receive Dividends
due on a dividend payment date). Upon receipt of such Notice of Occurrence, any
holder of Junior Preferred Stock may, within the time period specified by the
Company, notify the Company, by first class mail, postage


                                      B-7
<PAGE>   100

prepaid, as to whether such holder elects to exercise the redemption right. If
the holders of a majority of the outstanding shares of Junior 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
Junior Preferred Stock at such redemption price within sixty (60) days after
receiving such majority election in accordance with the procedures set forth in
Section 8(e) hereof; provided, however, that in order for the Company to effect
such redemption, no shares of PIK Preferred Stock may be outstanding; and
provided further that if the holders of a majority of the outstanding shares of
Junior Preferred Stock elect to exercise their redemption right pursuant to this
Section 8(c), such redemption shall be deferred until such time that no shares
of PIK Preferred Stock are outstanding. If the holders of less than a majority
of the outstanding shares of Junior Preferred Stock elect to require such
redemption, no shares of Junior Preferred Stock shall be redeemed as a result of
the occurrence of such Change in Control. For purposes of this Section 8(c), a
"Change in Control" shall be defined as: (i) the acquisition of more than 50% of
the outstanding shares of Common Stock by any one holder other than the holders
of Common Stock immediately following the Merger (as hereinafter defined; each
such holder being hereinafter referred to as an "Initial Holder") or (ii) the
acquisition by a Person that is not an Initial Holder or an Affiliate thereof of
a number of shares of Common Stock that is more than the aggregate number of
shares of Common Stock then held by the Initial Holders and their Affiliates.

                           (d) Status of Redeemed Shares. At the time of
redemption specified in the resolution of the Board authorizing such redemption,
the rights of the holders of the Junior Preferred Stock redeemed shall cease,
except for the right to receive the Liquidation Preference without interest
(subject to the right each such record holder to receive Dividends due on a
dividend payment date).

                           (e) Notice of Redemption, Etc. Except as otherwise
provided herein, the Company shall (i) mail written notice of each redemption of
any Junior 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), as the case may be, to the applicable
holder of Junior Preferred Stock, against delivery by such holder to the Company
of those certificates representing Junior Preferred Stock held by such holder
which have then been so redeemed. In case fewer than the total number of shares
of Junior Preferred Stock represented by any certificate are redeemed, a new
certificate representing the number of unredeemed shares of Junior 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 Junior Preferred Stock.

                  (9) General Provisions.

                           (a) If any of the Junior Preferred Stock certificates

Preferred Stock certificate and indemnity, if requested, satisfactory to the
Company.

                           (b) The term "Merger" shall mean the merger of HB
Merger LLC into the Company which occurred on [ ], 2000.

                           (c) 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 of the
Company.

                           (d) No holder of shares of Junior Preferred Stock
shall, 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.

                           (e) The headings of the sections, subsections,
clauses and subclauses hereof are for convenience of reference only and shall
not define, limit or affect any of the provisions hereof.

                           (f) Each holder of Junior Preferred Stock, by
acceptance thereof, acknowledges and agrees that payments of Dividends on and
Liquidation Preference of Junior Preferred Stock, and exchange, redemption and
repurchase of Junior 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.

                           (g) 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. "Business Day"
means any day except a Saturday, Sunday or other day on which commercial banks

                                 Indemnification

                  SECTION 1. Indemnification. The Company shall indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of the Company) by reason of the fact that he is or was a Director,
officer, employee or agent of the Company, or is or was serving at the request
of the Company 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 the Company, and, with respect to
any criminal action or proceeding, 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 the Company, and, with respect to any criminal
action or proceeding, had reasonable cause to believe that his conduct was
unlawful.

                                       7
<PAGE>   109

                  The Company shall 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 the Company to procure a judgment in its
favor by reason of the fact that he is or was a Director, officer, employee or
agent, of the Company as a Director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, against
expenses (including attorneys' fees) actually and reasonably incurred by him in
connection with the defense or settlement of such action or suit if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the Company and except that no indemnification shall be made
in respect of any claim, issue or matter as to which such person shall have been
adjudged to be liable for negligence or misconduct in the performance of his
duty to the Company unless and only to the extent that the Court of Chancery of
the State of Delaware or the court in which such action or suit was brought
shall determine upon application that, despite the adjudication of liability but
in view of all the circumstances of the case, such person is fairly and
reasonably entitled to indemnity for such expenses which the Court of chancery
of the State of Delaware or such other court shall deem proper.

                  To the extent that a Director, officer, employee or agent of
the Company has been successful on the merits or otherwise in defense of any
action, suit or proceeding referred to in the first two paragraphs of this
Section 1 of Article V or in defense of any claim, issue or matter therein, he
shall be indemnified against expenses (including attorneys' fees) actually and
reasonably incurred by him in connection therewith.

                  Any indemnification under the first two paragraphs of this
Section 1 of Article V (unless ordered by a court) shall be made by the Company
only as authorized in the specific case upon a determination that
indemnification of the Director, officer, employee or agent is proper in the
circumstances because he has met the applicable standard of conduct set forth in
the first two paragraphs of this Section 1 of Article V. Such determination
shall be made (1) by the Board of Directors by a majority vote of a quorum
consisting of Directors who were not parties to such action, suit or proceeding,
or (2) 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 (3) by the shareholders.

                  Expenses incurred in defending a civil or criminal action,
suit or proceeding shall be paid by the Company in advance of the final
disposition of such action, suit or proceeding upon receipt of an undertaking by
or on behalf of the Director, officer, employee or agent to repay such amount if
it shall ultimately be determined that he is not entitled to be indemnified by
the Company as authorized in this Section 1 of Article V.

                  The indemnification provided by this Section 1 of Article V
shall not be deemed exclusive of any other rights to which those seeking
indemnification may be entitled under any by-law, agreement, vote of
shareholders or disinterested Directors or otherwise, both as to action in their
official capacity and as to action in another capacity


                                       8
<PAGE>   110

while holding such office, and shall continue as to a person who has ceased to
be a Director, officer, employee or agent and shall inure to the benefit of the
heirs, executors and administrators of such a person.

                  The Company shall have power to purchase and maintain
insurance on behalf of any person who is or was a Director, officer, employee or
agent of the Company, or is or was serving at the request of the Company as a
Director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise 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 the Company would have the power to indemnify him against such
liability under the provisions of this Section 1 of Article V.

                  For purposes of this Section 1 of Article V, references to
"the Company" shall include, in addition to the resulting corporation, any
constituent corporation (including any constituent of a constituent) absorbed in
a consolidation or merger which, if its separate existence had continued, would
have had power and authority to indemnify its Directors, officers, and
employees, or agents, so that any person who is or was a Director, officer,
employee or agent of such constituent corporation, or is or was serving at the
request of such constituent corporation as a Director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise shall stand in the same position under the provisions of this Section
1 of Article V with respect to the resulting or surviving corporation as he
would have with respect to such constituent corporation if its separate
existence had continued.

                  For purposes of this Section 1 of Article V, references to
"other enterprises" shall include employee benefit plans; references to "fines"
shall include any excise taxes assessed on a person with respect to an employee
benefit plan; and references to "serving at the request of the corporation"
shall include any service as a Director, officer, employee or agent of the
Company which imposes duties on, or involves services by, such Director,
officer, employee, or agent with respect to an employee benefit plan, its
participants, or beneficiaries; and a person who acted in good faith and in a
manner he reasonably believed to be in the interest of the participants and
beneficiaries of an employee benefit plan shall be deemed to have acted in a
manner "not opposed to the best interests of the Company" as referred to in this
Section 1 of Article V.

                                   ARTICLE V

                                Books and Records

                  SECTION 1. Location. The books and records of the Company may
be kept at such place or places within or outside the State of Delaware as the
Board of Directors or the officers in charge thereof may from time to time
determine. The record books containing the names and addresses of all
stockholders, the number and class of shares of stock held by each and the dates
when they respectively became the owners of


                                       9

record thereof shall be kept by the Secretary as prescribed in the By-laws and
by such officer or agent as shall be designated by the Board of Directors.

                  SECTION 2. Addresses of Stockholders. Notices of meetings and
all other corporate notices may be delivered personally or mailed to each
stockholder at the stockholder's address as it appears on the records of the
Company.

                  SECTION 3. Fixing Date for Determination of Stockholders of
Record. (a) In order that the Company may determine the stockholders entitled to
notice of or to vote at any meeting of stockholders or any adjournment thereof,
the Board of Directors may fix a record date, which record date shall not
precede the date upon which the resolution fixing the record date is adopted by
the Board of Directors and which record date shall not be more than 60 nor less
than 10 days before the date of such meeting. If no record date is fixed by the
Board of Directors, the record date for determining stockholders entitled to
notice of or to vote at a meeting of stockholders shall be at the close of
business on the day next preceding the day on which notice is given, or, if
notice is waived, at the close of business on the day next preceding the day on
which the meeting is held. A determination of stockholders of record entitled to
notice of or to vote at a meeting of stockholders shall apply to any adjournment
of the meeting; provided, however, that the Board of Directors may fix a new
record date for the adjourned meeting.

                  (b) In order that the Company may determine the stockholders
entitled to consent to corporate action in writing without a meeting, the Board
of Directors may fix a record date, which record date shall not precede the date
upon which the resolution fixing the record date is adopted by the Board of
Directors and which date shall not be more than 10 days after the date upon
which the resolution fixing the record date is adopted by the Board of
Directors. If no record date has been fixed by the Board of Directors, the
record date for determining stockholders entitled to consent to corporate action
in writing without a meeting, when no prior action by the Board of Directors is
required, shall be the first date on which a signed written consent setting
forth the action taken or proposed to be taken is delivered to the Company by
delivery to its registered office in this State, its principal place of
business, or an officer or agent of the Company having custody of the book in
which proceedings of meetings of stockholders are recorded. Delivery made to the
Company's registered office shall be by hand or by certified or registered mail,
return receipt requested. If no record date has been fixed by the Board of
Directors and prior action by the Board of Directors is required by this
chapter, the record date for determining stockholders entitled to consent to
corporate action in writing without a meeting shall be at the close of business
on the day on which the Board of Directors adopts the resolution taking such
prior action.

                  (c) In order that the Company may determine the stockholders
entitled to receive payment of any dividend or other distribution or allotment
of any rights or the stockholders entitled to exercise any rights in respect of
any change, conversion or exchange of stock, or for the purpose of any other
lawful action, the Board of Directors may fix a record date, which record date
shall not precede the date upon which the


                                       10
<PAGE>   112

resolution fixing the record date is adopted and which record date shall be not
more than 60 days prior to such action. If no record date is fixed, the record
date for determining stockholders for any such purpose shall be at the close of
business on the day on which the Board of Directors adopts the resolution
relating thereto.

                                  ARTICLE VII

                         Certificates Representing Stock

                  SECTION 1. Certificates; Signatures. The shares of the Company
shall be represented by certificates, provided that the Board of Directors of
the Company may provide by resolution or resolutions that some or all of any or
all classes or series of its stock shall be uncertificated shares. Any such
resolution shall not apply to shares represented by a certificate until such
certificate is surrendered to the Company. Notwithstanding the adoption of such
a resolution by the Board of Directors, every holder of stock of the Company
represented by certificates and upon request every holder of uncertificated
shares shall be entitled to have a certificate, signed by or in the name of the
Company by the Chairman or Vice-Chairman of the Board of Directors, or the
President or Vice-President, and by the Treasurer or an Assistant Treasurer, or
the Secretary or an Assistant Secretary of the Company, representing the number
of shares registered in certificate form. Any and all signatures on any such
certificate may be facsimiles. In case any officer, transfer agent or registrar
who has signed or whose facsimile signature has been placed upon a certificate
shall have ceased to be such officer, transfer agent or registrar before such
certificate is issued, it may be issued by the Company with the same effect as
if he were such officer, transfer agent or registrar at the date of issue. The
name of the holder of record of the shares represented thereby, with the number
of such shares and the date of issue, shall be entered on the books of the
Company.

                  SECTION 2. Transfers of Stock. Upon compliance with provisions
restricting the transfer or registration of transfer of shares of stock, if any,
shares of capital stock shall be transferable on the books of the Company only
by the holder of record thereof in person, or by duly authorized attorney, upon
surrender and cancellation of certificates for a like number of shares, properly
endorsed, and the payment of all taxes due thereon.

                  SECTION 3. Fractional Shares. The Company may, but shall not
be required to, issue certificates for fractions of a share where necessary to
effect authorized transactions, or the Company may pay in cash the fair value of
fractions of a share as of the time when those entitled to receive such
fractions are determined, or it may issue scrip in registered or bearer form
over the manual or facsimile signature of an officer of the Company or of its
agent, exchangeable as therein provided for full shares, but such scrip shall
not entitle the holder to any rights of a stockholder except as therein
provided.

                                       11
<PAGE>   113

                  The Board of Directors shall have power and authority to make
all such rules and regulations as it may deem expedient concerning the issue,
transfer and registration of certificates representing shares of the Company.

                  SECTION 4. Lost, Stolen or Destroyed Certificates. The Company
may issue a new certificate of stock in place of any certificate, theretofore
issued by it, alleged to have been lost, stolen or destroyed, and the Board of
Directors may require the owner of any lost, stolen or destroyed certificate, or
his legal representative, to give the Company a bond sufficient to indemnify the
Company against any claim that may be made against it on account of the alleged
loss, theft or destruction of any such certificate or the issuance of any such
new certificate.

                  Subject to applicable law and the Certificate of
Incorporation, the Board of Directors shall have full power to determine whether
any, and, if any, what part of any, funds legally available for the payment of
dividends shall be declared as dividends and paid to stockholders; the division
of the whole or any part of such funds of the Company shall rest wholly within
the lawful discretion of the Board of Directors, and it shall not be required at
any time, against such discretion, to divide or pay any part of such funds among
or to the stockholders as dividends or otherwise; and before payment of any
dividend, there may be set aside out of any funds of the Company available for
dividends such sum or sums as the Board of Directors from time to time, in its
absolute discretion, thinks proper as a reserve or reserves to meet
contingencies, or for equalizing dividends, or for repairing or maintaining any
property of the Company, or for such other purpose as the Board of Directors
shall think conducive to the interest of the Company, and the Board of Directors
may modify or abolish any such reserve in the manner in which it was created.

                                   ARTICLE IX

                                  Ratification

                  Any transaction, questioned in any law suit on the ground of
lack of authority, defective or irregular execution, adverse interest of
director, officer or stockholder, non-disclosure, miscomputation, or the
application of improper principles or practices of accounting, may be ratified
before or after judgment, by the Board of Directors or by the stockholders, and
if so ratified shall have the same force and effect as if the questioned
transaction had been originally duly authorized. Such ratification shall be
binding upon the Company and its stockholders and shall constitute a bar to any
claim or execution of any judgment in respect of such questioned transaction.

the Certificate of Incorporation or by law, a written waiver thereof, signed by

stated therein, shall be deemed equivalent to notice.

accounts as may be authorized by the Board of Directors, the primary financial
officer or any person designated by said primary financial officer, whether or
not an employee of the Company, may authorize such bank accounts to be opened or

primary financial officer, or other person so designated by the Treasurer.

                  SECTION 2. Contracts. The Board of Directors may authorize any

                MANAGEMENT OF THE COMPANY AND CERTAIN ACTIVITIES

      2.1 Board of Directors.

            2.1.1 Board Representation. Unless otherwise increased by a majority
of the Holders of the issued and outstanding Securities in accordance with the
DGCL, the Board shall consist of nine (9) directors, five being appointed by the
HMTF Group, two being appointed by the BSMB Group, one being appointed by the
Trust (each of HMTF Group, BSMB Group and the Trust, a "Nominating Holder," and
each such director so appointed, a "Party Designee") and one of whom shall be
the chief executive officer of the Company. To the extent that the Board is
increased as contemplated in the preceding sentence, the HMTF Group shall always
(subject to Section 2.1.3) have the right to appoint a majority of the Board
and, so long as the HMTF Group has the right to and does appoint a majority of
such increased Board, the BSMB Group shall have the right (subject to Section
2.1.3) to appoint that percentage of the members of the increased Board (and the
Board shall be further increased if reasonably required to so accomplish the
desired result) that is as close as practicable to the ratio of seven (7) board
members for the HMTF Group for every three (3) board members for the BSMB Group.
Each Holder shall vote his or its shares of Securities at any regular or special
meeting of stockholders of the Company or in any written consent executed in
lieu of such a meeting of stockholders and shall take all other actions required
by the DGCL to give effect to the agreements contained in this Stockholders'
Agreement (including without limitation the election of persons designated by
the Nominating Holders to be elected as directors as described in the preceding
sentence) and to ensure that the certificate of incorporation of the Company and
bylaws of the Company as in effect immediately following the Effective Date do
not, at any time thereafter, conflict in any respect with the provisions of this
Stockholders' Agreement. In order to effectuate the provisions of this Section
2.1, each of the HMTF Group or the BSMB Group hereby agrees that when any action
or vote is required to be taken by such Holder pursuant to this Stockholders'
Agreement, such Holder shall use his or its best efforts to call, or cause the
appropriate officers and directors of the Company to call, a special or annual
meeting of stockholders of the Company, as the case may be, and each Holder
agrees when any action or vote is required to be taken by such Holder pursuant
to this Agreement, such Holder shall execute or cause to be executed a consent
in writing in lieu of any such meetings pursuant to Section 228(a) of the DGCL
if requested by the Board. Any committee formed by the Board shall include one
(1) or more representatives of the HMTF Group and the BSMB Group unless
otherwise consented to by the Required Holders.

            2.1.2 Vacancies. If, prior to his or her election to the Board
pursuant to Section 2.1.1 hereof, any Party Designee shall be unable or
unwilling to serve as a director of the Company, the respective Nominating
Holder appointing such Party Designee shall be entitled to nominate a
replacement who shall then be a Party Designee for purposes of this Section 2.
If, following an election to the Board pursuant to Section 2.1.1 hereof, any
Party Designee shall resign, be removed (which shall occur without cause, only
upon request of the Nominating Holder appointing such Party Designee, but with
cause may occur upon a vote of the Required Holders), or be unable to serve for
any


                                       11
<PAGE>   131
reason prior to the expiration of his term as a director of the Company
(including disability or death), the respective Nominating Holder appointing
such Party Designee shall, within thirty (30) days of such event, notify the
Board in writing of a replacement Party Designee, and either (i) the Holders
shall vote their shares of Securities, at any regular or special meeting called
for the purpose of filling positions on the Board or in any written consent
executed in lieu of such a meeting of stockholders, and shall take all such
other actions necessary to ensure the election to the Board of such replacement
Party Designee to fill the unexpired term of the Party Designee who such new
Party Designee is replacing or (ii) the Nominating Holders shall cause their
respective Party Designees to elect such replacement Party Designee to fill the
unexpired term of the Party Designee who such new Party Designee is replacing.
If a Nominating Holder requests that their Party Designee be removed as a
Director (with or without cause) by written notice thereof to the Company, then
the Company shall take all actions necessary to effect, and each of the Holders
shall vote all its or his capital stock in favor of, such removal upon such
request (or, if applicable, provide a written consent).

            2.1.3 Termination of Rights. The right of a Nominating Holder to
appoint directors under Section 2.1.1, but not the obligation of such Nominating
Holder to vote its shares of Securities as provided herein, shall terminate at
the time at which such Nominating Holder ceases to own its respective Required
Percentage of the Fully-Diluted Common Stock; provided that to the extent the
HMTF Group's rights under Section 2.1.1 terminate as provided in this Section
2.1.3, the HMTF Group shall have the right to appoint the number of directors
equal to the greater of (x) the number of directors which may be appointed by
the BSMB Group pursuant to Section 2.1.1 and (y) the number of directors
calculated in accordance with the following formula: an amount (which shall be
rounded up to the next whole number if such amount is not a whole number) equal
to (I) the percentage of Fully-Diluted Common Stock Beneficially Owned by the
HMTF Group multiplied by (II) the number of directors that exist immediately
prior to the occurrence of such event which may be appointed to the Board
pursuant to Section 2.1.1, rounded to the nearest whole number.

            2.1.4 Costs and Expenses. The Company will pay all reasonable
out-of-pocket expenses incurred by the Party Designees in connection with their
participation in meetings of the Board (and committees thereof) and the Boards
of Directors (and committees thereof) of the Subsidiaries of the Company.

      2.2 Other Activities of the Holders; Fiduciary Duties. It is understood
and accepted that the Holders and their Affiliates have interests in other
business ventures which may be in conflict with the activities of the Company
and its Subsidiaries and that, subject to applicable law, nothing in this
Stockholders' Agreement shall limit the current or future business activities of
the Holders whether or not such activities are competitive with those of the
Company and its Subsidiaries. Nothing in this Stockholders' Agreement, express
or implied, shall relieve any officer or director of the Company of any
fiduciary or other duties or obligations they may have to the Company's
stockholders.

      2.3 Request for Sale of Company by HMTF. Notwithstanding anything to the
contrary contained in this Stockholders' Agreement but subject to Section 8.2,
at any time after the Effective Date, HMTF may give written notice to the
Company and the Holders requiring a sale of the Company. Such sale may be
effected pursuant to a stock or asset disposition, as determined by HMTF in its
sole discretion. To the extent necessary in order to consummate such sale, each
Holder hereby agrees to vote all of its or his capital stock in favor of such
sale upon the request of HMTF. Notwithstanding anything to the contrary
contained herein, each of the Holders shall receive the same consideration for
each of the Securities it then Beneficially Owns as the HMTF Group in such sale.
If such sale is to be consummated pursuant to a stock purchase, all Holders
selling pursuant to this Section 2.3 shall be treated identically with the
Securities being sold by the HMTF Group in all respects; provided, that no
Holder other than the Holders in the HMTF Group shall be required to make any
representations or warranties in connection with such Transfer other than
representations and warranties as to (i) such Holder's ownership of his or its
Securities to be Transferred free and clear of all liens, claims and
encumbrances other than those arising hereunder, (ii) such Holder's power and
authority to effect such Transfer, and (iii) such matters pertaining to
compliance with securities laws as the purchaser may reasonably require. No
Holder not in the HMTF Group shall be required to agree to any matter other than
the foregoing representations and warranties and transfer of its Securities. Any
indemnity obligations of the Holders other than the HMTF Group arising under the
definitive documentation for such sale shall be several and shall relate solely
to the representations and warranties described above and shall be in proportion
to and in an amount no greater than the consideration received by such Holder in
such sale. In no event shall any Holder be required to sell any securities if
the sale thereof would be in violation of any law, rule, regulation, statute or
order of any governmental entity.

            its or their Registrable Shares which, in the aggregate, have an
            offering value of at least Twenty-Five Million Dollars ($25,000,000)
            or, if less, all of their Registrable Shares (an "R/S Demand
            Registration").

                  (b) Each R/S Demand Request shall specify the number of
            Registrable Shares proposed to be sold. Subject to Section 3.1.8,
            the Company shall file the R/S Demand Registration as promptly as


                                       13
<PAGE>   133
            practicable but in no event later than ninety (90) days after
            receiving an R/S Demand Request (the "R/S Required Filing Date") and
            shall use all commercially reasonable efforts to cause the same to
            be declared effective by the SEC as promptly as practicable after
            such filing; provided, that the Company need effect only (i) five
            (5) R/S Demand Registrations pursuant to an R/S Demand Request made
            by the HMTF Demand Group, (ii) only three (3) R/S Demand
            Registrations pursuant to an R/S Demand Request made by the BSMB
            Demand Group, and (iii) only one (1) R/S Demand Registration
            pursuant to an R/S Demand Request made by the Trust; provided,
            further, that if more than twenty percent (20%) of any Registrable
            Shares requested to be registered pursuant to an R/S Demand Request
            made under paragraph (a) of this Section 3.1.1 are excluded from the
            applicable R/S Demand Registration pursuant to Section 3.1.6 below,
            the R/S Demand Requesting Holder or R/S Demand Requesting Holders
            shall have the right, with respect to each such exclusion, to
            request one (1) additional R/S Demand Registration under such
            paragraph (a).

                  (c) Notwithstanding paragraph (b) of this Section 3.1.1, in
            the event that the Company shall be eligible to effect a
            registration under the Securities Act using Form S-3 (or other
            comparable short-form registration statement) ("S-3 Eligibility"),
            (i) any Qualified Holder shall be entitled to request an unlimited
            number of R/S Demand Registrations of such Registrable Shares on
            Form S-3 (or other comparable short-form registration statement) (an
            "R/S S-3 Registration"), and (ii) the Company shall be required to
            use its commercially reasonable efforts to effect such R/S S-3
            Registrations, and such R/S S-3 Registrations shall not be
            considered an R/S Demand Registration for purposes of the limits on
            the number of R/S Demand Registrations contained in such paragraph
            (b) nor be subject to the $25,000,000 threshold set forth in
            paragraph (a) of this Section 3.1.1, but all such requests shall be
            considered R/S Demand Requests for other purposes under this Article
            III.

            3.1.2 Request for Registration of PIK Preferred.

                  (a) At any time after the Effective Date, the Trust may
            request the Company, in writing (a "PIK Demand Request"), to effect
            the registration under the Securities Act of all or part of its
            shares of PIK Preferred which, in the aggregate, have an offering
            value of at least Twenty-Five Million Dollars ($25,000,000) (a "PIK
            Demand Registration").

                  (b) Each PIK Demand Request shall specify the number of shares
            of PIK Preferred proposed to be sold. Subject to Section 3.1.8, the
            Company shall file the PIK Demand Registration as promptly as
            practicable but in no event later than ninety (90) days after
            receiving a PIK Demand Request (the "PIK Required Filing Date") and
            shall use all commercially reasonable efforts to cause the same to
            be declared effective


                                       14
<PAGE>   134
            by the SEC as promptly as practicable after such filing; provided,
            that the Company need effect only four (4) PIK Demand Registrations
            pursuant to PIK Demand Requests made by the Trust; provided,
            further, that if more than twenty percent (20%) of any shares of PIK
            Preferred requested to be registered pursuant to a PIK Demand
            Request made under paragraph (a) of this Section 3.1.2 are excluded
            from the applicable PIK Demand Registration pursuant to Section
            3.1.6 below, the Trust shall have the right, with respect to each
            such exclusion, to request one (1) additional PIK Demand
            Registration under such paragraph (a).

                  (c) Notwithstanding paragraph (b) of this Section 3.1.2, in
            the event that the Company has S-3 Eligibility, (i) the Trust shall
            be entitled to request an unlimited number of PIK Demand
            Registrations of shares of PIK Preferred on Form S-3 (or other
            comparable short-form registration statement) (an "PIK S-3
            Registration"), and (ii) the Company shall be required to use its
            commercially reasonable efforts to effect such PIK S-3
            Registrations, and such PIK S-3 Registrations shall not be
            considered a PIK Demand Registration for purposes of the limits on
            the number of PIK Demand Registrations contained in such paragraph
            (b) nor be subject to the $25,000,000 threshold set forth in
            paragraph (a) of this Section 3.1.2, but all such requests shall be
            considered PIK Demand Requests for other purposes under this Article
            III.

            3.1.3 Company S-3 Obligation. The Company agrees to use all
reasonable efforts to make all required filings with the SEC that are within the
Company's control so as to maintain its S-3 Eligibility.

            3.1.4 Effective Registration and Expenses. A registration will not
count as a Demand Registration until it has become effective (unless the
Requesting Holders withdraw all their Registrable Securities and the Company has
performed its obligations hereunder in all material respects, in which case such
demand will count as a Demand Registration unless the Requesting Holders pay all
Registration Expenses, as hereinafter defined, in connection with such withdrawn
registration); provided, that if, after it has become effective, an offering of
Registrable Securities pursuant to a registration is interfered with by any stop
order, injunction, or other order or requirement of the SEC or other
governmental agency or court, such registration will be deemed not to have been
effected and will not count as a Demand Registration.

            3.1.5 Selection of Underwriters. The offering of Registrable
Securities pursuant to a Demand Registration shall be in the form of a "firm
commitment" underwritten offering if so requested by the Requesting Holders. The
Requesting Holders of a majority of the Registrable Securities to be registered
in a Demand Registration shall select the investment banking firm or firms to
manage the underwritten offering; provided that such selection shall be subject
to the consent of the Company, which consent shall not be unreasonably withheld.


                                       15
<PAGE>   135
            3.1.6 Priority on Demand Registrations. No securities to be sold for
the account of any Person (including the Company) other than a Requesting Holder
shall be included in a Demand Registration unless the managing underwriter or
underwriters shall advise the Company or the Requesting Holders in writing that
the inclusion of such securities will not materially and adversely affect the
price or completion of the offering (a "Material Adverse Effect"). Furthermore,
in the event the managing underwriter or underwriters shall advise the Company
or the Requesting Holders that the amount of Registrable Securities proposed to
be included in such Demand Registration by the Requesting Holders is
sufficiently large to cause a Material Adverse Effect (whether or not a Person
other than a Requesting Holder has requested registration), the Registrable
Securities of the Requesting Holders to be included in such Demand Registration
shall equal the number of shares which the Company is so advised can be sold in
such offering without a Material Adverse Effect and such shares shall be
allocated pro rata among the Requesting Holders on the basis of the number of
Registrable Securities in each class Beneficially Owned by each such Requesting
Holder. No Holder may participate in any registration statement hereunder unless
such Holder (x) agrees to sell such Holder's Registrable Securities on the basis
provided in any underwriting arrangements approved by the Company and (y)
completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements, and other documents, each in customary form, reasonably
required under the terms of such underwriting arrangements; provided, however,
that no such Holder shall be required to make any representations or warranties
in connection with any such registration other than representations and
warranties as to (i) such Holder's ownership of his or its Registrable
Securities to be sold or Transferred free and clear of all liens, claims, and
encumbrances, (ii) such Holder's power and authority to effect such Transfer,
and (iii) such matters pertaining to compliance with federal and state
securities laws as may be reasonably requested; provided further, however, that
the obligation of such Holder to indemnify pursuant to any such underwriting
arrangements shall be several, and the liability of each such Holder will be in
proportion to, and provided further that such liability will be limited to, the
net amount received by such Holder from the sale of his or its Registrable
Securities pursuant to such registration.

            3.1.7 Rights of Nonrequesting Holders. Upon receipt of any Demand
Request, the Company shall promptly (but in any event within ten (10) days) give
written notice of such proposed Demand Registration to all other Holders, who
shall have the right, exercisable by written notice to the Company within twenty
(20) days after their receipt of the Company's notice, to elect to include in
such Demand Registration such portion of their Registrable Securities as they
may request. All Holders requesting to have their Registrable Securities
included in a Demand Registration in accordance with the preceding sentence
shall be deemed to be "Requesting Holders" for purposes of this Section 3.1.

            3.1.8 Deferral of Filing. The Company may defer the filing (but not
the preparation) of a registration statement required by Section 3.1 until a
date not later than one hundred eighty (180) days after the Required Filing Date
(or, if longer, one hundred eighty (180) days after the effective date of the
registration statement contemplated by clause (ii) below) if (i) at the time the
Company receives the Demand Request, the


                                       16
<PAGE>   136
Company or any of its Subsidiaries are engaged in confidential negotiations or
other confidential business activities, disclosure of which would, in the
reasonable judgment of the Company, be required in such registration statement
(but would not be required if such registration statement were not filed), and
the Board determines in good faith that such disclosure would be materially
detrimental to the Company and its stockholders, or (ii) prior to receiving the
Demand Request, the Board had determined to effect a registered underwritten
public offering of the Company's securities for the Company's account and the
Company had taken substantial steps (including, but not limited to, selecting a
managing underwriter for such offering) and is proceeding with reasonable
diligence to effect such offering. A deferral of the filing of a registration
statement pursuant to this Section 3.1.8 shall be lifted, and the requested
registration statement shall be filed forthwith, if, in the case of a deferral
pursuant to clause (i) of the preceding sentence, the negotiations or other
activities are disclosed or terminated, or, in the case of a deferral pursuant
to clause (ii) of the preceding sentence, the proposed registration for the
Company's account is abandoned. In order to defer the filing of a registration
statement pursuant to this Section 3.1.8, the Company shall promptly, upon
determining to seek such deferral, deliver to each Requesting Holder a
certificate signed by an executive officer of the Company stating that the
Company is deferring such filing pursuant to this Section 3.1.8 and a general
statement of the reason for such deferral and an approximation of the
anticipated delay. Within twenty (20) days after receiving such certificate, the
holders of a majority of the Registrable Securities Beneficially Owned by the
Requesting Holders and for which registration was previously requested may
withdraw such Demand Request by giving notice to the Company; if withdrawn, the
Demand Request shall be deemed not to have been made for all purposes of this
Agreement. The Company may defer the filing of a particular registration
statement pursuant to this Section 3.1.8 only once.

      3.2 Piggyback Registrations.

            3.2.1 Right to Piggyback. Each time the Company proposes to register
any of its equity securities at any time after a Qualified IPO (other than
pursuant to an Excluded Registration or a Demand Request) under the Securities
Act for sale to the public (whether for the account of the Company or the
account of any securityholder of the Company) and the form of registration
statement to be used permits the registration of Registrable Shares, the Company
shall give prompt written notice to each Holder of Registrable Shares (which
notice shall be given not less than thirty (30) days prior to the effective date
of the Company's registration statement), which notice shall offer each such
Holder the opportunity to include any or all of its or his Registrable Shares in
such registration statement, subject to the limitations contained in Section
3.2.2 hereof. Each Holder other than a Management Holder (including Henry until
such time as he ceases to be employed by the Company), and, to the extent
permitted by the underwriter, each Management Holder, who desires to have its or
his Registrable Shares included in such registration statement shall so advise
the Company in writing (stating the number of shares desired to be registered)
within twenty (20) days after the date of such notice from the Company. Any
Holder shall have the right to withdraw such Holder's request for inclusion of
such Holder's Registrable Shares in any registration statement pursuant to this
Section 3.2.1 by giving written notice to the Company of such withdrawal.
Subject


                                       17
<PAGE>   137
to Section 3.2.2 below, the Company shall include in such registration statement
all such Registrable Shares so requested to be included therein; provided,
however, that the Company may at any time withdraw or cease proceeding with any
such registration if it shall at the same time withdraw or cease proceeding with
the registration of all other equity securities originally proposed to be
registered.

            3.2.2 Priority on Registrations. If the managing underwriter advises
the Company in writing that the number of equity securities requested to be
included in a registration for which rights have been requested pursuant to
Section 3.2 by all Persons (including the Company) exceeds the number of shares
which can be sold in such offering without causing a Material Adverse Effect,
the Company will be obligated to include in such registration only (i) first,
any and all equity securities for sale by the Company, (ii) second, to the
extent of any remaining Registrable Shares which may be sold in such offering
without causing a Material Adverse Effect, each other Holder shall be entitled
to include any and all Registrable Shares Beneficially Owned by such Holder in
the registration (pro rata based on the total number of such Registrable Shares
Beneficially Owned by each such Holder), and (iii) third, to the extent of any
remaining equity securities which the Company is advised may be sold in such
offering without causing a Material Adverse Effect, pro rata among any other
Persons holding equity securities requested to be included pursuant to any other
registration rights that may have been, or may hereafter be, granted by the
Company (on the basis of the total number of equity securities that each holder
thereof Beneficially Owns) on the basis of the number of equity securities of
the Company Beneficially Owned by such Person. If as a result of the provisions
of this Section 3.2.2 any Holder shall not be entitled to include all
Registrable Shares in a registration that such Holder has requested to be so
included, such Holder may withdraw such Holder's request to include Registrable
Shares in such registration statement. No Holder may participate in any
registration statement hereunder unless such Holder (x) agrees to sell such
Holder's Registrable Shares on the basis provided in any underwriting
arrangements approved by the Company and (y) completes and executes all
questionnaires, powers of attorney, indemnities, underwriting agreements, and
other documents, each in customary form, reasonably required under the terms of
such underwriting arrangements; provided, however, that no such Holder shall be
required to make any representations or warranties in connection with any such
registration other than representations and warranties as to (i) such Holder's
ownership of his or its Registrable Shares to be sold or transferred free and
clear of all liens, claims, and encumbrances, (ii) such Holder's power and
authority to effect such transfer, and (iii) such matters pertaining to such
Person's compliance with securities laws as may be reasonably requested;
provided further, however, that the obligation of such Holder to indemnify
pursuant to any such underwriting arrangements shall be several, and the
liability of each such Holder will be in proportion to, and provided further
that such liability will be limited to, the net amount received by such Holder
from the sale of his or its Registrable Shares pursuant to such registration.

      3.3 Shelf Registration.

            3.3.1 Obligation to File. At any time after one hundred eighty (180)
days after the consummation of a Qualified IPO, either the HMTF Demand Group, on


                                       18
<PAGE>   138
behalf of the HMTF Group, or the BSMB Demand Group, on behalf of the BSMB Group,
may request (the "Shelf Registration Request") the Company to file with the SEC,
as soon as practicable, a registration statement for a resale offering to be
made on a continuous basis pursuant to Rule 415 promulgated under the Securities
Act covering all of the Registrable Shares Beneficially Owned by the HMTF Group
or the BSMB Group, as the case may be (the "Shelf Registration"). The Shelf
Registration shall be on Form S-3 under the Securities Act or another
appropriate form permitting registration of all Registrable Shares Beneficially
Owned by the HMTF Group and the BSMB Group for resale (the "Shelf Shares") by
the Holders of such Shelf Shares in the manner or manners designated by them
(including, without limitation, one or more underwritten offerings). The Company
shall use its commercially reasonable efforts to cause the Shelf Registration to
be declared effective pursuant to the Securities Act as promptly as reasonably
practicable following the filing thereof, but in no event later than the 180th
day after the Shelf Registration Request, and to keep the Shelf Registration
continuously effective under the Securities Act for a one (1) year period
following the date of the effectiveness of such Shelf Registration, or such
shorter period ending when either (1) all Shelf Shares covered by the Shelf
Registration have been sold in the manner set forth and as contemplated in the
Shelf Registration or pursuant to Rule 144 promulgated under the Securities Act
or (2) there cease to be outstanding any Shelf Shares (the "Effectiveness
Period"). Notwithstanding anything to the contrary contained herein, at such
time as (a) the HMTF Control Group ceases to own a majority of the Securities
owned by the HMTF Group, it shall no longer be permitted to make a Shelf
Registration Request under this Section 3.3.1 and (b) the BSMB Control Group
ceases to own a majority of the Securities owned by the BSMB Group, it shall no
longer be permitted to make a Shelf Registration Request pursuant to this
Section 3.3.1.

            3.3.2 Maintenance of Effectiveness. The Company shall use its
commercially reasonable efforts to keep the Shelf Registration continuously
effective for the Effectiveness Period, by supplementing and amending the Shelf
Registration if required by the rules, regulations or instructions applicable to
the registration form used for such Shelf Registration, if required by the
Securities Act or if reasonably requested by Holders of Shelf Shares covered by
such registration statement or by any underwriter of such Shelf Shares.

            3.3.3 Certain Limitations on Sales. Notwithstanding anything to the
contrary in Section 3.3.1 or Section 3.3.2 hereof, the Company may, by
delivering written notice to the Holders of Shelf Shares, prohibit offers and
sales of Shelf Shares pursuant to the Shelf Registration until a date not later
than ninety (90) days after the date of such notice if (i) the Company or any of
its Subsidiaries is engaged in confidential negotiations or other confidential
business activities, disclosure of which would, in the reasonable judgment of
the Company, be required in such registration statement (but would not be
required if such registration statement were not filed), and the Board
determines in good faith that such disclosure would be materially detrimental to
the Company and its stockholders (provided, however, that upon the public
disclosure by the Company of the negotiations or business activities described
above, the suspension of the use of the Shelf Registration pursuant to this
Section 3.3.3 shall cease and the Company shall promptly notify Holders that
dispositions of Shelf Shares may be resumed) or (ii) the Company is


                                       19
<PAGE>   139
required to file a post effective amendment to such Shelf Registration. In no
event may the Company prohibit offers and sales of Shelf Shares pursuant to the
Shelf Registration (i) for a period of more than ninety (90) days following the
delivery by the Company of the notice provided for in the first sentence of this
Section 3.3.3 or, (ii) more than twice in any 12-month period.

      3.4 Holdback Agreement. Unless the managing underwriter otherwise agrees,
each of the Company, and the Holders agree (and the Company agrees, in
connection with any underwritten registration, to use its reasonable efforts to
cause its Affiliates to agree) not to effect any public sale or private offer or
distribution of any Securities or Common Stock Equivalents during the ten (10)
business days prior to the effectiveness under the Securities Act of any
underwritten registration and during such time period after the effectiveness
under the Securities Act of any underwritten registration (not to exceed one
hundred eighty (180) days) (except, if applicable, as part of such underwritten
registration) as the Company and the managing underwriter may agree.

      3.5 Registration Procedures. Whenever any Holder has requested that any
Registrable Securities be registered pursuant to this Stockholders' Agreement,
the Company will use its commercially reasonable efforts to effect the
registration and the sale of such Registrable Securities in accordance with the
intended method of disposition thereof, and pursuant thereto the Company will in
addition to the other requirements set forth in this Article III as promptly as
practicable:

                  (i) prepare and file with the SEC a registration statement on
            Form S-3 or any appropriate form under the Securities Act, together
            with a prospectus, to be used in connection therewith, with respect
            to such Registrable Securities and use its commercially reasonable
            efforts to cause such registration statement to become effective;

                  (ii) prepare and file with the SEC such amendments,
            post-effective amendments, and supplements to such registration
            statement and the prospectus included therein as may be necessary to
            keep such registration statement effective for a period of not less
            than one hundred eighty (180) days (or such lesser period as is
            necessary for the underwriters in an underwritten offering to sell
            unsold allotments) or, in the case of a Shelf Registration, for the
            period specified in Section 3.3.2, and comply with the provisions of
            the Securities Act with respect to the disposition of all securities
            covered by such registration statement during such period in
            accordance with the intended methods of disposition by the sellers
            thereof set forth in such registration statement;

                  (iii) furnish to each seller of Registrable Securities and the
            underwriters of the securities being registered such number of
            copies of such registration statement, each amendment and supplement
            thereto, the prospectus to be used in connection therewith
            (including each preliminary prospectus), any documents incorporated
            by reference therein and such other documents as such seller or
            underwriters may reasonably request in


                                       20
<PAGE>   140
            order to facilitate the disposition of the Registrable Securities
            owned by such seller or the sale of such securities by such
            underwriters (it being understood that, subject to Section 3.6 and
            the requirements of the Securities Act and applicable state
            securities laws, the Company consents to the use of the prospectus
            and any amendment or supplement thereto by each seller and the
            underwriters in connection with the offering and sale of the
            Registrable Securities covered by the registration statement of
            which such prospectus, amendment or supplement is a part);

                  (iv) use its commercially reasonable efforts to register or
            qualify such Registrable Securities under such other securities or
            blue sky laws of such jurisdictions as the managing underwriter
            reasonably requests (or, in the event the registration statement
            does not relate to an underwritten offering, as the holders of a
            majority of such Registrable Securities may reasonably request); use
            its commercially reasonable efforts to keep each such registration
            or qualification (or exemption therefrom) effective during the
            period in which such registration statement is required to be kept
            effective; and do any and all other acts and things which may be
            reasonably necessary or advisable to enable each seller to
            consummate the disposition of such Registrable Securities owned by
            such seller in such jurisdictions (provided, however, that the
            Company will not be required to (A) qualify generally to do business
            in any jurisdiction where it would not otherwise be required to
            qualify but for this subparagraph or (B) consent to general service
            of process in any such jurisdiction);

            (v) promptly notify each seller and each underwriter and (if
            requested by any such Person) confirm such notice in writing (A)
            when a prospectus or any prospectus supplement or post-effective
            amendment has been filed and, with respect to a registration
            statement or any post-effective amendment, when the same has become
            effective, (B) of the issuance by any state securities or other
            regulatory authority of any order suspending the qualification or
            exemption from qualification of any of the Registrable Securities
            under state securities or "blue sky" laws or the initiation of any
            proceedings for that purpose, and (C) of the happening of any event
            which makes any statement of a material fact made in a registration
            statement or related prospectus untrue or which requires the making
            of any changes in such registration statement, prospectus or
            documents so that they will not contain any untrue statement of a
            material fact or omit to state any material fact required to be
            stated therein or necessary to make the statements therein not
            misleading in light of the circumstances under which they were made,
            and, as promptly as practicable thereafter, prepare and file with
            the SEC and furnish a supplement or amendment to such prospectus so
            that, as thereafter deliverable to the purchasers of such
            Registrable Securities, such prospectus will not contain any untrue
            statement of a material fact or omit

<PAGE>   141
            a material fact necessary to make the statements therein, in light
            of the circumstances under which they were made, not misleading;

                  (vi) make generally available to the Company's securityholders
            an earnings statement satisfying the provisions of Section 11(a) of
            the Securities Act no later than thirty (30) days after the end of
            the twelve (12) month period beginning with the first day of the
            Company's first fiscal quarter commencing after the effective date
            of a registration statement, which earnings statement shall cover
            said twelve (12) month period, and which requirement will be deemed
            to be satisfied if the Company timely files complete and accurate
            information on Forms 10-Q, 10-K and 8-K under the Exchange Act and
            otherwise is in accordance with the definitions set forth in Rule
            158 under the Securities Act;

                  (vii) if requested by the managing underwriter or any seller
            promptly incorporate in a prospectus supplement or post-effective
            amendment such information as the managing underwriter or any seller
            reasonably requests to be included therein, including, without
            limitation, with respect to the Registrable Securities being sold by
            such seller, the purchase price being paid therefor by the
            underwriters and with respect to any other terms of such
            underwritten offering of the Registrable Securities to be sold in
            such offering, and promptly make all required filings of such
            prospectus supplement or post-effective amendment;

                  (viii) as promptly as reasonably practicable after filing with
            the SEC of any document which is incorporated by reference into a
            registration statement (in the form in which it was incorporated),
            deliver a copy of each such document to each seller;

                  (ix) cooperate with the sellers and the managing underwriter,
            if applicable, to facilitate the timely preparation and delivery of
            certificates (which shall not bear any restrictive legends unless
            required under applicable law) representing securities sold under
            any registration statement, and enable such securities to be in such
            denominations and registered in such names as the managing
            underwriter, if applicable, or such sellers may request and keep
            available and make available to the Company's transfer agent prior
            to the effectiveness of such registration statement a supply of such
            certificates;

                  (x) promptly make available after a request therefor, for
            inspection by any seller, any underwriter participating in any
            disposition pursuant to any registration statement, if applicable,
            and any attorney, accountant or other agent or representative
            retained by any such seller or underwriter (collectively, the
            "Inspectors"), all financial and other records, pertinent corporate
            documents and properties of the Company (collectively, the
            "Records"), as shall be reasonably necessary to enable them to
            exercise their due diligence responsibility, and cause the


                                       22
<PAGE>   142
            Company's officers, directors and employees to supply all
            information reasonably requested by any such Inspector in connection
            with such registration statement; provided, that, unless the
            disclosure of such Records is necessary to avoid or correct a
            misstatement or omission in the registration statement or the
            release of such Records is ordered pursuant to a subpoena or other
            order from a court of competent jurisdiction, the Company shall not
            be required to provide any information under this subparagraph (x)
            if (A) the Company believes, after consultation with counsel for the
            Company, that to do so would cause the Company to forfeit an
            attorney-client privilege that was applicable to such information or
            (B) if either (1) the Company has requested and been granted from
            the SEC confidential treatment of such information contained in any
            filing with the SEC or documents provided supplementally or
            otherwise or (2) the Company reasonably determines in good faith
            that such Records are confidential and so notifies the Inspectors in
            writing unless prior to furnishing any such information with respect
            to (A) or (B) such Holder of Registrable Securities requesting such
            information agrees to enter into a confidentiality agreement in
            customary form and subject to customary exceptions; and provided,
            further that each Holder of Registrable Securities agrees that it
            will, upon learning that disclosure of such Records is sought in a
            court of competent jurisdiction, give notice to the Company and
            allow the Company, at its expense, to undertake appropriate action
            and to prevent disclosure of the Records deemed confidential;

                  (xi) furnish to each seller and underwriter, if applicable, a
            signed counterpart of (A) an opinion or opinions of counsel to the
            Company, and (B) in the case of a "firm commitment" underwritten
            offering, a comfort letter or comfort letters from the Company's
            independent public accountants, each in customary form and covering
            such matters of the type customarily covered by opinions or comfort
            letters, as the case may be, as the sellers or managing underwriter
            reasonably requests;

                  (xii) cause the Registrable Securities included in any
            registration statement to be (A) listed on each securities exchange,
            if any, on which the same class of securities of the Company are
            then listed, or (B) , if not listed on a national securities
            exchange, authorized to be quoted and/or listed for trading (to the
            extent applicable) on the National Association of Securities
            Dealers, Inc. ("NASD") Automated Quotation System or the Nasdaq
            National Market if the Registrable Securities so qualify;

                  (xiii) provide a CUSIP number for the Registrable Securities
            included in any registration statement not later than the effective
            date of such registration statement;

                  (xiv) cooperate with each seller and each underwriter, if
            applicable, participating in the disposition of such Registrable
            Securities


                                       23
<PAGE>   143
            and their respective counsel in connection with any filings required
            to be made with the NASD;

                  (xv) during the period when the prospectus is required to be
            delivered under the Securities Act, promptly file all documents
            required to be filed with the SEC pursuant to Sections 13(a), 13(c),
            14 or 15(d) of the Exchange Act;

                  (xvi) notify each seller of Registrable Securities promptly of
            any request by the SEC for the amending or supplementing of such
            registration statement or prospectus or for additional information;

                  (xvii) prepare and file with the SEC promptly any amendments
            or supplements to such registration statement or prospectus which,
            in the opinion of counsel for the Company or the managing
            underwriter, if applicable, is required in connection with the
            distribution of the Registrable Securities;

                  (xviii) in the case of a "firm commitment" underwritten
            offering, enter into such agreements (including underwriting
            agreements in the managing underwriter's customary form) as are
            customary in connection with an underwritten registration; and

                  (xix) advise each seller of such Registrable Securities, as
            promptly as reasonably practicable after it shall receive notice or
            obtain knowledge thereof, of the issuance of any stop order by the
            SEC suspending the effectiveness of such registration statement or
            the initiation or threatening of any proceeding for such purpose and
            promptly use its best efforts to prevent the issuance of any stop
            order or to obtain its withdrawal at the earliest possible moment if
            such stop order should be issued.

      3.6 Suspension of Dispositions. Each Holder agrees by acquisition of any
Registrable Securities that, upon receipt of any notice (a "Suspension Notice")
from the Company of the happening of any event of the kind described in Section
3.5(v)(C) such Holder will forthwith discontinue disposition of Registrable
Securities pursuant to a registration statement until such Holder's receipt of
the copies of the supplemented or amended prospectus, or until it is advised in
writing (the "Advice") by the Company that the use of the prospectus may be
resumed, and has received copies of any additional or supplemental filings which
are incorporated by reference in the prospectus, and, if so directed by the
Company, such Holder will deliver to the Company all copies, other than
permanent file copies then in such Holder's possession, of the prospectus
covering such Registrable Securities current at the time of receipt of such
notice. In the event the Company shall give any such notice, the time period
regarding the effectiveness of registration statements set forth in Section
3.5(ii) hereof shall be extended by the number of days during the period from
and including the date of the giving of the Suspension Notice to and including
the date when each seller of Registrable Securities covered by


                                       24
<PAGE>   144
such registration statement shall have received the copies of the supplemented
or amended prospectus or the Advice. The Company shall use its commercially
reasonable efforts and take such actions as are reasonably necessary to render
the Advice as promptly as practicable.

      3.7 Registration Expenses. All expenses incident to the Company's
performance of or compliance with this Article 3 including, without limitation,
all registration and filing fees, all fees and expenses associated with filings
required to be made with the NASD (including, if applicable, the fees and
expenses of any "qualified independent underwriter" as such term is defined in
Schedule E of the By-Laws of the NASD, and of its counsel), as may be required
by the rules and regulations of the NASD, fees and expenses of compliance with
securities or "blue sky" laws (including reasonable fees and disbursements of
counsel in connection with "blue sky" qualifications of the Registrable
Securities), rating agency fees, printing expenses (including expenses of
printing certificates for the Registrable Securities in a form eligible for
deposit with Depository Trust Company and of printing prospectuses if the
printing of prospectuses is requested by a holder of Registrable Securities),
messenger and delivery expenses, the Company's internal expenses (including
without limitation all salaries and expenses of its officers and employees
performing legal or accounting duties), the fees and expenses incurred in
connection with any listing of the Registrable Securities, fees and expenses of
counsel for the Company and its independent certified public accountants
(including the expenses of any special audit or "cold comfort" letters required
by or incident to such performance), securities acts liability insurance (if the
Company elects to obtain such insurance), the fees and expenses of any special
experts retained by the Company in connection with such registration, and the
fees and expenses of other persons retained by the Company and reasonable fees
and expenses of one firm of counsel for the sellers (which shall be selected by
the holders of a majority of the Registrable Securities being included in any
particular registration statement) (all such expenses being herein called
"Registration Expenses") will be borne by the Company whether or not any
registration statement becomes effective; provided that in no event shall
Registration Expenses include any underwriting discounts, commissions, or fees
attributable to the sale of the Registrable Securities or any counsel (except as
provided above), accountants, or other persons retained or employed by the
Holders.

      3.8 Indemnification.

            3.8.1 The Company agrees to indemnify and reimburse, to the fullest
extent permitted by law, each seller of Registrable Securities, and each of its
employees, advisors, agents, representatives, partners, officers, trustees and
directors and each Person who controls (within the meaning of the Securities Act
or the Exchange Act) such seller and any agent or investment advisor thereof
(collectively, the "Seller Affiliates") (A) against any and all losses, claims,
damages, liabilities, and expenses, joint or several (including, without
limitation, attorneys' fees and disbursements except as limited by Section
3.8.3) based upon, arising out of, related to or resulting from any untrue
statement or alleged untrue statement of a material fact contained in any
registration statement, prospectus, or preliminary prospectus or any amendment
thereof or supplement thereto, or any omission or alleged omission of a material
fact required to be


                                       25
<PAGE>   145
stated therein or necessary to make the statements therein not misleading in
light of the circumstances under which they were made, and (B) against any and
all costs and expenses (including reasonable fees and disbursements of counsel)
as may be reasonably incurred in investigating, preparing, or defending against
any litigation, or investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever based upon, arising out
of, related to or resulting from any such untrue statement or omission or
alleged untrue statement or omission, to the extent that any such expense or
cost is not paid under subparagraph (A) above; except insofar as the same are
made in reliance upon and in strict conformity with information furnished in
writing to the Company by such seller or any Seller Affiliate for use therein or
arise from such seller's or any Seller Affiliate's failure to deliver a copy of
the registration statement or prospectus or any amendments or supplements
thereto after the Company has furnished such seller or Seller Affiliate with a
sufficient number of copies of the same. The reimbursements required by this
Section 3.8.1 will be made by periodic payments during the course of the
investigation or defense, as and when bills are received or expenses incurred.

            3.8.2 In connection with any registration statement in which a
seller of Registrable Securities is participating, each such seller will furnish
to the Company in writing such information and affidavits as the Company
reasonably requests for use in connection with any such registration statement
or prospectus and, to the fullest extent permitted by law, each such seller will
indemnify the Company and its directors and officers and each Person who
Controls the Company against any and all losses, claims, damages, liabilities,
and expenses (including, without limitation, reasonable attorneys' fees and
disbursements except as limited by Section 3.8.3) based upon, arising out of,
related to, or resulting from any untrue statement or alleged untrue statement
of a material fact contained in the registration statement, prospectus, or any
preliminary prospectus or any amendment thereof or supplement thereto, or any
omission or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein not misleading, but only to the extent
that such untrue statement or alleged untrue statement or omission or alleged
omission is contained in any information or affidavit so furnished in writing by
such seller or any of its Seller Affiliates specifically for inclusion in the
registration statement; provided that the obligation to indemnify will be
several, not joint and several, among such sellers of Registrable Securities,
and the liability of each such seller of Registrable Securities will be in
proportion to, and provided further that such liability will be limited to, the
net amount received by such seller from the sale of Registrable Securities
pursuant to such registration statement; provided, however, that such seller of
Registrable Securities shall not be liable in any such case to the extent that
prior to the filing of any such registration statement or prospectus or
amendment thereof or supplement thereto, such seller has furnished in writing to
the Company information expressly for use in such registration statement or
prospectus or any amendment thereof or supplement thereto which corrected or
made not misleading information previously furnished to the Company.

            3.8.3 Any Person entitled to indemnification hereunder will (A) give
prompt written notice to the indemnifying party of any claim with respect to
which it seeks indemnification (provided that the failure to give such notice
shall not limit the


                                       26
<PAGE>   146
rights of such Person unless the indemnifying party is materially prejudiced
thereby) and (B) unless in such indemnified party's reasonable judgment after
advice from independent counsel a conflict of interest between such indemnified
and indemnifying parties may exist with respect to such claim, permit such
indemnifying party to assume the defense of such claim with counsel reasonably
satisfactory to the indemnified party; provided, however, that any person
entitled to indemnification hereunder shall have the right to employ separate
counsel and to participate in the defense of such claim, and the fees and
expenses of such counsel shall be at the expense of such person unless (X) the
indemnifying party has agreed to pay such fees or expenses, or (Y) the
indemnifying party shall have failed to assume the defense of such claim or
failed to employ counsel reasonably satisfactory to such person. If such defense
is not assumed by the indemnifying party as permitted hereunder, the
indemnifying party will not be subject to any liability for any settlement made
by the indemnified party without its written consent (but such consent will not
be unreasonably withheld). If such defense is assumed by the indemnifying party
pursuant to the provisions hereof, such indemnifying party shall not settle or
otherwise compromise the applicable claim unless (1) such settlement or
compromise contains a full and unconditional release of the indemnified party
with respect to the claim or (2) the indemnified party otherwise consents in
writing. An indemnifying party who is not entitled to, or elects not to, assume
the defense of a claim will not be obligated to pay the fees and expenses of
more than one counsel for all parties indemnified by such indemnifying party
with respect to such claim, unless in the reasonable judgment of any indemnified
party, a conflict of interest may exist between such indemnified party and any
other of such indemnified parties with respect to such claim, in which event the
indemnifying party shall be obligated to pay the reasonable fees and
disbursements of such additional counsel or counsels.

            3.8.4 Each party hereto agrees that, if for any reason the
indemnification provisions contemplated by Section 3.8.1 or Section 3.8.2 are
unavailable to or insufficient to hold harmless an indemnified party in respect
of any losses, claims, damages, liabilities, or expenses (or actions in respect
thereof) referred to therein, then each indemnifying party shall contribute to
the amount paid or payable by such indemnified party as a result of such losses,
claims, damages, liabilities, or expenses (or actions in respect thereof) in
such proportion as is appropriate to reflect the relative fault of the
indemnifying party and the indemnified party in connection with the actions
which resulted in the losses, claims, damages, liabilities or expenses as well
as any other relevant equitable considerations. The relative fault of such
indemnifying party and indemnified party shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material
fact or omission or alleged omission to state a material fact relates to
information supplied by such indemnifying party or indemnified party, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission. The parties hereto agree that it
would not be just and equitable if contribution pursuant to this Section 3.8.4
were determined by pro rata allocation (even if the sellers or any underwriters
or all of them were treated as one entity for such purpose) or by any other
method of allocation which does not take account of the equitable considerations
referred to in this Section 3.8.4. The amount paid or payable by an indemnified
party as a result of the losses, claims, damages, liabilities, or expenses (or
actions in respect thereof) referred to above shall be


                                       27
<PAGE>   147
deemed to include any legal or other fees or expenses reasonably incurred by
such indemnified party in connection with investigating or, except as provided
in Section 3.8.3, defending any such action or claim. Notwithstanding the
provisions of this Section 3.8.4, no seller shall be required to contribute an
amount greater than the dollar amount by which the net proceeds received by such
seller with respect to the sale of any Registrable Securities exceeds the amount
of damages which such seller has otherwise been required to pay by reason of any
and all untrue or alleged untrue statements of material fact or omissions or
alleged omissions of material fact made in any registration statement,
prospectus or preliminary prospectus or any amendment thereof or supplement
thereto related to such sale of Registrable Securities. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any Person who was not
guilty of such fraudulent misrepresentation. The sellers' obligations in this
Section 3.8.4 to contribute shall be several in proportion to the amount of
Registrable Securities registered by them and not joint.

            If indemnification is available under this Section 3.8, the
indemnifying parties shall indemnify each indemnified party to the full extent
provided in Section 3.8.1 and Section 3.8.2 without regard to the relative fault
of said indemnifying party or indemnified party or any other equitable
consideration provided for in this Section 3.8.4 subject, in the case of the
Holders, to the limited dollar amounts set forth in Section 3.8.2.

            3.8.5 The indemnification and contribution provided for under this
Stockholders' Agreement will remain in full force and effect regardless of any
investigation made by or on behalf of the indemnified party or any officer,
director, or controlling Person of such indemnified party and will survive the
transfer of securities.

                                   ARTICLE 4
                             TRANSFERS OF SECURITIES

      4.1 Preemptive Rights.

            4.1.1 Rights to Participate in Future Sales. In case the Company
proposes to issue or sell (a) any shares of Common Stock or Common Stock
Equivalents to any Person, or (b) any other security of the Company to any one
or more members of the BSMB Control Group or the HMTF Control Group (the
"Offered Securities"), the Company shall, no later than thirty (30) days prior
to the consummation of such transaction (a "Preemptive Rights Transaction"),
give notice in writing of such Preemptive Rights Transaction (the "Offer
Notice") to each Qualified Holder. The Offer Notice shall describe the proposed
Preemptive Rights Transaction, identify the proposed purchaser, and contain an
offer (the "Preemptive Rights Offer") to sell to each Qualified Holder who
certifies (to the reasonable satisfaction of the Company) that such Qualified
Holder is an Accredited Investor (an "Accredited Offeree"), at the same price
and for the same consideration to be paid by the proposed purchaser, all or part
of such Accredited Offeree's pro rata portion of the Offered Securities (which
shall be the percentage ownership of the Fully-Diluted Common Stock Beneficially
Owned by such Qualified Holder, excluding, for the purposes of such calculation,
any shares of Common Stock


                                       28
<PAGE>   148
issuable upon exercise of any Common Stock Equivalents granted pursuant to any
employee, officer or director benefit plan or arrangement multiplied by the
number of Offered Securities to be issued, and the number of Offered Securities
to be sold to the prospective purchaser shall be reduced by the number of
Offered Securities agreed to be purchased by each Qualified Holder pursuant to
this Section 4.1.1). If any such Qualified Holder fails to accept such offer by
written notice thirty (30) days after its receipt of the Offer Notice, the
Company may proceed with the proposed issue or sale of the Offered Securities,
free of any right on the part of such Qualified Holder under this Section 4.1.1
in respect thereof. In the event any Subsidiary of the Company proposes to issue
or sell any security of such Subsidiary to any Holder or its Affiliates, the
Company shall use its reasonable best efforts to cause such Subsidiary to offer
pre-emptive rights with respect to such security to the other Qualified Holders
on terms and conditions substantially similar to those contained in this Section
4.1.1.

            4.1.2 Exceptions to Preemptive Rights. This Section 4.1 shall not
apply to (i) issuances or sales of Common Stock or Common Stock Equivalents to
employees, officers, and/or directors of the Company and/or any of its
Subsidiaries pursuant to employee benefit or similar plans or arrangements of
the Company and/or its Subsidiaries, (ii) issuances or sales of Common Stock or
Common Stock Equivalents upon exercise of any Common Stock Equivalent, (iii)
securities distributed or set aside ratably to all holders of Common Stock and
Common Stock Equivalents (or any class or series thereof) on a per share
equivalent basis, (iv) issuances or sales of Common Stock or Common Stock
Equivalents pursuant to a registered underwritten public offering or issuances
in, a merger of the Company or a Subsidiary of the Company into or with another
entity or an acquisition by the Company or a Subsidiary of the Company of
another business or corporation or (v) the issuance of the Securities in the
Merger. In the event of any issuances or sales of Common Stock or Common Stock
Equivalents as a unit with any other security of the Company or its
Subsidiaries, the preemptive rights under this Section 4.1 shall be applicable
to the entire unit rather than only the Common Stock or Common Stock Equivalent
included in the unit.

      4.2 Drag Along Rights.

            4.2.1 Applicability. In connection with any Transfer by members of
the HMTF Group of shares of Securities representing more than seventy-five
percent (75%) of the shares of Securities then Beneficially Owned by the HMTF
Group (a "Significant Drag Sale"), the HMTF Group shall have the right to
require all, but not less than all of the non-selling Holders (each, a
"Co-Seller") to Transfer a portion of its Securities which represents the same
percentage of the Fully Diluted Common Stock Beneficially Owned by such
Co-Seller as the shares being disposed of by the HMTF Group represent of the
Fully Diluted Common Stock Beneficially Owned by the HMTF Group. (For example,
if the HMTF Group is selling seventy-five percent (75%) of their Fully Diluted
Common Stock position, each Co-Seller shall be required to sell seventy-five
percent (75%) of its Fully Diluted Common Stock position.) All Securities
Transferred by Holders pursuant to this Section 4.2 shall be sold for the same
consideration, and otherwise treated identically with the Securities being sold
by the HMTF Group in all respects; provided, that (x) the Co-Seller shall not be
required to make any representations or warranties in


                                       29
<PAGE>   149
connection with such Transfer other than representations and warranties as to
(i) such Co-Seller's ownership of his or its Securities to be Transferred free
and clear of all liens, claims and encumbrances, other than those arising
hereunder, (ii) such Co-Seller's power and authority to effect such Transfer,
and (iii) such matters pertaining to compliance with securities laws as the
Transferee may reasonably require and (y) any indemnity obligations of such
Co-Seller arising under the definitive documentation for such Transfer shall be
several, and shall relate solely to the representations and warranties described
above and shall be in an amount no greater than the consideration received by
the Co-Seller in such sale. No Co-Seller shall be required to agree to any other
matter other than the foregoing representations and warranties and Transfer of
its Securities. In no event shall any Co-Seller be required to sell any
Securities if the sale thereof would be in violation of any law, rule,
regulation, statute or order of any governmental entity.

            4.2.2 Notice of Significant Drag Sale. HMTF, on behalf of the HMTF
Group, shall give each Co-Seller at least thirty (30) days' prior written notice
of any Significant Drag Sale as to which the HMTF Group intends to exercise its
rights under Section 4.2. If the HMTF Group elects to exercise its rights under
Section 4.2, the Co-Sellers shall take such actions as may be reasonably
required and otherwise cooperate in good faith with the HMTF Group in connection
with consummating the Significant Drag Sale (including, without limitation, the
voting of any Securities or other voting capital stock of the Company to approve
such Significant Drag Sale). At the closing of such Significant Drag Sale, each
Co-Seller shall deliver certificates for all shares of Securities to be sold by
such Co-Seller, duly endorsed for transfer, with the signature guaranteed, to
the purchaser against payment of the appropriate purchase price.

      4.3 Tag Along Rights.

            4.3.1 Applicability. In the event that any Holder alone or together
with its Affiliates including in the case of HMTF Group, all members of the HMTF
Group, and, in the case of BSMB Group, all members of the BSMB Group (the
"Selling Holder") desires to directly or indirectly effect a sale of shares of
Securities representing five percent (5%) of the shares of the Fully-Diluted
Common Stock in one or a series of transactions (a "Significant Tag Sale"), and,
in the case of the HMTF Group, if applicable, it does not elect to exercise its
rights (if any) under Section 4.2 hereof, then at least thirty (30) days prior
to the closing of such Significant Tag Sale, the Selling Holder shall make an
offer (the "Participation Offer") to each Holder (a "Tag Co-Seller") to include
in the proposed Significant Tag Sale a portion of its Securities which
represents the same percentage of such Tag Co-Seller's Fully-Diluted Common
Stock as the shares being sold by the Selling Holder represent of its
Fully-Diluted Common Stock; provided that, if the consideration to be received
by the Selling Holder includes any securities, only Tag Co-Sellers who have
certified to the reasonable satisfaction of the Selling Holder that they are
Accredited Investors shall be entitled to participate in such transfer, unless
the transferee consents otherwise. No Holder shall include terms in a
Significant Tag Sale deliberately included for the sole purpose of excluding a
Tag Co-Seller's participation in such Significant Tag Sale.


                                       30
<PAGE>   150
            4.3.2 Terms of Participation Offer. The Participation Offer shall
describe the terms and conditions of the proposed Significant Tag Sale and shall
be conditioned upon (i) the consummation of the transactions contemplated in the
Participation Offer with the Transferee named therein, and (ii) each Tag
Co-Seller's execution and delivery of all agreements and other documents as the
Selling Holder is required to execute and deliver in connection with such
Significant Tag Sale (provided that the Tag Co-Seller shall not be required to
make any representations or warranties in connection with such Transfer other
than representations and warranties as to (A) such Tag Co-Seller's ownership of
his or its Securities to be Transferred free and clear of all liens, claims, and
encumbrances, (B) such Tag Co-Seller's power and authority to effect such
transfer and (C) such matters pertaining to compliance with securities laws as
the transferee may reasonably require). If any Tag Co-Seller shall accept the
Participation Offer, the Selling Holder shall reduce, to the extent necessary,
the number of Securities it otherwise would have sold in the proposed transfer
so as to permit those Tag Co-Sellers who have accepted the Participation Offer
to sell the number of Securities that they are entitled to sell under this
Section 4.3, and the Selling Holder and such Tag Co-Sellers shall transfer the
number of Securities specified in the Participation Offer to the proposed
transferee in accordance with the terms of such transfer as set forth in the
Participation Offer.

      4.4 Certain Events Not Deemed Transfers. In no event shall any exchange,
reclassification, or other conversion of shares into any cash, securities, or
other property pursuant to a merger or consolidation of the Company or any
Subsidiary with, or any sale or transfer by the Company or any Subsidiary of all
or substantially all its assets to, any Person constitute a Significant Drag
Sale of shares of Securities by the HMTF Group for purposes of Section 4.2 or a
Significant Tag Sale of shares of Securities by any Holder for purposes of
Section 4.3. In addition, Sections 4.2 and 4.3 hereof shall not apply to any
Transfer of shares of Securities (a) solely among members of the HMTF Group
and/or the BSMB Group, (b) by the BSMB Group or the HMTF Group to an Initial
Permitted Transferee as long as the BSMB Group or the HMTF Group, as the case
maybe, agrees with any Holder which would otherwise participate in such
Significant Tag Sale that it shall not permit the irrevocable proxy granted by
the Initial Permitted Transferee to be directly or indirectly exercised by any
other Person and that such proxy shall remain in force, or (c) by Henry to a
Henry Family Member (i) by will or the laws of descent and distribution or (ii)
by gift without consideration of any kind (a "Family Transfer").

      4.5 Transfer and Exchange. When Securities are presented to the Company
with a request to register the transfer of such Securities or to exchange such
Securities for Securities of other authorized denominations, the Company shall
register the transfer or make the exchange as requested if the requirements of
this Stockholders' Agreement for such transaction are met; provided, however,
that the Securities surrendered for transfer or exchange shall be duly endorsed
or accompanied by a written instrument of transfer in form satisfactory to the
Company, duly executed by the Holder thereof or its attorney and duly authorized
in writing. No service charge shall be made for any registration of transfer or
exchange, but the Company may require payment of a sum sufficient to cover any
transfer tax or similar governmental charge payable in connection therewith.

      4.6 Replacement Securities. If a mutilated Security is surrendered to the
Company or if the Holder of a Security claims and submits an affidavit or other
evidence, satisfactory to the Company, to the effect that the Security has been
lost, destroyed or wrongfully taken, the Company shall issue a replacement
Security if the Company's requirements are met. If required by the Company, such
Holder must provide an indemnity bond, or other form of indemnity, sufficient in
the judgment of the Company to protect the Company against any loss which may be
suffered. The Company may charge such Holder for its reasonable out-of-pocket
expenses in replacing a Security which has been mutilated, lost, destroyed, or
wrongfully taken.

      4.7 Concurrent Transfer of Securities. A Transfer of Common Stock may only
be made by a Holder if such Holder Transfers a percentage of the Junior
Preferred Stock Beneficially Owned by such Holder to the same Transferee in such
transaction equal to the percentage of Common Stock Beneficially Owned by such
Holder being Transferred.

                             LIMITATION ON TRANSFERS

      5.1 Restrictions on Transfer. The Securities shall not be Transferred or
otherwise conveyed, assigned or hypothecated before satisfaction of (i) the
conditions specified in Section 5.1, Section 5.2, and Section 5.3, which
conditions are intended to ensure compliance with the provisions of the
Securities Act with respect to the Transfer of any Security and (ii) if
applicable, Article 4 hereof. Any purported Transfer in violation of this
Article 5 and/or, if applicable, Article 4 hereof shall be void ab initio and of
no force or effect. Other than Transfers subject to Sections 4.2 or 4.3 hereof
and other than Transfers to the public pursuant to an effective registration
statement or sales to the public pursuant to Rule 144 under the Securities Act
otherwise permitted hereunder, each Holder will cause any proposed Transferee
(including any Initial Permitted Transferee, Henry Family Member or Group
Transferee) of any Security Beneficially Owned by it (other than a Group
Transferee) to agree to take and hold such Securities subject to the provisions
and upon the conditions specified in this Stockholders' Agreement, and to
execute and deliver to the Company an Instrument of Accession in the form of
Exhibit A hereto.

      5.2 Restrictive Legends.

            5.2.1 Securities Act Legend. Except as otherwise provided in Section
5.4 hereof, each Security Beneficially Owned by a Holder, and each Security
issued to any subsequent Transferee of such Security, shall be stamped or
otherwise imprinted with a legend in substantially the following form:

            THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, NOR PURSUANT TO THE
SECURITIES OR "BLUE SKY" LAWS OF ANY STATE. SUCH SECURITIES MAY NOT BE OFFERED,
SOLD, TRANSFERRED, PLEDGED, HYPOTHECATED OR OTHERWISE ASSIGNED, EXCEPT PURSUANT
TO (i) A REGISTRATION STATEMENT WITH RESPECT TO


                                       32
<PAGE>   152
SUCH SECURITIES WHICH IS EFFECTIVE UNDER SUCH ACT, (ii) RULE 144 UNDER SUCH ACT,
OR (iii) ANY OTHER EXEMPTION FROM REGISTRATION UNDER SUCH ACT.

            5.2.2 Other Legends. Except as otherwise permitted by the last
sentence of Section 5.1, each Security issued to each Holder or a subsequent
transferee shall include a legend in substantially the following form:

            THIS SECURITY IS SUBJECT TO RESTRICTIONS ON TRANSFER, VOTING AND
OTHER TERMS AND CONDITIONS SET FORTH IN THE STOCKHOLDERS' AGREEMENT DATED AS OF
_______________, ____, A COPY OF WHICH MAY BE OBTAINED FROM JOHNS MANVILLE
CORPORATION AT ITS PRINCIPAL EXECUTIVE OFFICES.

      5.3 Notice of Proposed Transfers. Other than with respect to a Transfer to
(a) an Initial Permitted Transferee, (b) a Henry Family Member, (c) a Group
Transferee or (d) in accordance with Article 3, prior to any Transfer or
attempted Transfer of any Security, the Holder of such Security shall (i) give
at least ten (10) days' prior written notice (a "Transfer Notice") to the
Company of such Holder's intention to effect such Transfer, and (ii) either (A)
provide to the Company an opinion reasonably satisfactory to the Company from
counsel who shall be reasonably satisfactory to the Company (or supply such
other evidence reasonably satisfactory to the Company) that the proposed
Transfer of such Security may be effected without registration under the
Securities Act, or (B) unless the Securities to be Transferred are registered
under the Exchange Act certify to the Company that the Holder reasonably
believes the proposed transferee is a "qualified institutional buyer" and that
such Holder has taken reasonable steps to make the proposed transferee aware
that such Holder may rely on Rule 144A under the Securities Act in effecting
such Transfer. After receipt of the Transfer Notice and opinion (if required),
the Company shall, within five (5) days thereof, so notify the Holder of such
Security and such Holder shall thereupon be entitled to Transfer such Security
in accordance with the terms of the Transfer Notice. Each Security issued upon
such Transfer shall bear the restrictive legend set forth in Section 5.2.1,
unless in the opinion of such counsel such legend is not required in order to
ensure compliance with the Securities Act. The Holder of the Security giving the
Transfer Notice shall not be entitled to Transfer such Security until receipt of
the notice from the Company under this Section 5.3. Prior to a Transfer of any
Security to (x) an Initial Permitted Transferee or (y) a Henry Family Member
pursuant to a Family Transfer, the Holder of such Security shall certify to the
Company that the Holder reasonably believes such Initial Permitted Transferee or
Henry Family Member, as the case may be, is an Accredited Investor. In addition,
notwithstanding anything to the contrary contained herein, any Transfer to a
Group Transferee may be made without the necessity of satisfaction of the
conditions set forth in this Section 5.3 (other than the condition contained in
the third sentence of this Section 5.3).

      5.4 Termination of Certain Restrictions. Notwithstanding the foregoing
provisions of this Section 5, the restrictions imposed by Section 5.2.1 upon the
transferability of the Securities and the legend requirements of Section 5.2.1
shall


                                       33
<PAGE>   153
terminate as to any Security (i) when and so long as such Security shall have
been effectively registered under the Securities Act and disposed of pursuant
thereto or (ii) when the Company shall have received an opinion of counsel
reasonably satisfactory to it that such Security may be freely transferred at
any time without registration thereof under the Securities Act and that such
legend may be removed. Whenever the restrictions imposed by Section 5.2.1 shall
terminate as to any Security, the Holder thereof shall be entitled to receive
from the Company, at the Company's expense, a new Security not bearing the
restrictive legend set forth in Section 5.2.1.

      6.2 Suspension and Termination of Special Stockholder Voting Rights.

            6.2.1 At the time a Suspension Event occurs, the Special Stockholder
Voting Rights granted to the Holders under Section 6.1 (other than clause (e)

(b) no longer reasonably believes it will be in default of the Senior Debt
Covenants, as certified in writing to HMTF by the chief financial officer of the
Company.

            6.2.2 The Special Stockholder Voting Rights shall terminate at the

      7.1 IPO Rights; Sale Rights;.

            7.1.1 IPO Rights.

            (a) If a Qualified IPO does not occur by the fifth (5th) anniversary
      of the Effective Date, BSMB shall have the right to request a Qualified
      IPO (the "Requested IPO") by delivering a written notice (the "IPO
      Notice") to the Company and HMTF requesting that the Company effect a
      Qualified IPO and, subject to Section 7.1.2, the Company shall use
      commercially reasonable efforts to effect the Requested IPO as soon as
      practicable thereafter.

            (b) The right of BSMB to require a Qualified IPO pursuant to this
      Section 7.1.1 shall terminate at the earlier to occur of (i) the time at
      which the Holders comprising the BSMB Group have transferred more than
      twenty-five percent (25%) of the Securities Beneficially Owned by them on
      the Effective Date or (ii) the time at which the BSMB Control Group shall
      cease to own a majority of the Securities at any time owned by the BSMB
      Group.

            7.1.2 Sale Rights. In the event BSMB has exercised its right to
request a Qualified IPO under Section 7.1.1, HMTF shall have the right to cause
the Company to hire a nationally recognized investment bank for the purpose of
marketing the Company for sale (the "Sale Option"), but the Company shall not be
required to effect the Requested IPO until the time at which the Sale Option
terminates as contemplated in the proviso to the following sentence. If HMTF
elects to exercise the Sale Option, HMTF shall deliver a notice to BSMB, within
thirty (30) days following the delivery of the IPO Notice to HMTF by BSMB,
indicating its intent to exercise the Sale Option and the Company shall
thereafter use its reasonable best efforts to sell all of the equity securities


                                       35
<PAGE>   155
or all or substantially all of the assets of the Company (including by way of
merger or consolidation); provided that in the event a definitive agreement for
the sale of the Company is not entered into within six (6) months after delivery
of the notice of Sale Option by HMTF to BSMB, under this Section 7.1.2, the
right of the Company to exercise the Sale Option shall terminate and BSMB shall
thereafter have the right to require the Company to effect a Qualified IPO in
accordance with the terms of Section 7.1.1.

      7.2 Company Call; Purchase Price.

            7.2.1 Company Call

            (a) If any Management Holder (other than Henry) (i) voluntarily
      terminates his employment with the Company, (ii) has his employment
      terminated at any time by the Company for Cause (as defined in such
      Management Holder's employment agreement), (iii) voluntarily terminates
      his employment with the Company and executes and delivers to the Company a
      non-compete agreement (A) in form and substance substantially similar to
      the non-compete provisions set forth in such Management Holder's
      employment agreement (without giving effect to any change of control
      provision contained therein) or (B) if such Management Holder's employment
      agreement does not contain such non-compete provisions, in form and
      substance satisfactory to the Company or (iv) is terminated by the Company
      without Cause (in each case, a "Terminated Management Holder"), then the
      Company will have the option to purchase (the "Company Call"), and if the
      Company Call is exercised by the Company, such Management Holder shall
      sell to the Company, all or any portion (at the Company's option) of the
      shares of Common Stock and Management Securities Beneficially Owned by
      such Management Holder. For purposes of this Section 7.2.1(a), termination
      of any Management Holder's employment with the Company as the result of
      such Management Holder's death or permanent disability (as defined in the
      Company's Board of Director-approved disability policy, as in effect from
      time to time) shall be deemed to constitute termination of such Management
      Holder's employment by the Company without Cause.

            (b) If Henry (i) voluntarily terminates his employment with the
      Company prior to the second anniversary of the Effective Date, or (ii) has
      his employment terminated at any time by the Company for Cause (as defined
      in the Henry Employment Agreement), then the Company will have a Company
      Call, and if the Company Call is exercised by the Company, Henry (and any
      Henry Family Member to whom Henry has transferred Securities pursuant to a
      Family Transfer) shall sell to the Company, all or any portion (at the
      Company's option) of the shares of Common Stock and Management Securities
      Beneficially Owned by Henry and all such Henry Family Members.

            (c) The Company shall give notice in writing to the Terminated
      Management Holder or Henry, as the case may be, of the exercise of the
      Company Call within one hundred eighty (180) days from the date of the


                                       36
<PAGE>   156
      termination of the Terminated Management Holder's or Henry's employment,
      as applicable. If no notice is given within the time limit specified
      above, the Company Call shall terminate.

            7.2.2 Purchase Price

            (a) In the case of any exercise by the Company of the Company Call
      following termination of employment described in either clause of (a) or
      (b) of Section 7.2.1, the purchase price payable by the Company for the
      Common Stock and the Management Securities being purchased will be a cash
      amount equal to the Fair Market Value of such Common Stock and Management
      Securities. For purposes of this Section 7.2.2, "Fair Market Value" means
      the fair market value of the Common Stock and Management Securities as
      determined by the Board in good faith as of the date of such exercise of
      the Company Call.

            (b) The closing of a purchase under this Section 7.2.2 shall take
      place at the Company's principal executive offices within thirty (30) days
      after the purchase price has been determined in accordance with clause (a)
      above. At such closing, the Management Holder shall deliver to the Company
      the certificates or instruments evidencing the Common Stock and Management
      Securities being purchased (free of all liens, claims and encumbrances),
      duly endorsed (or accompanied by duly executed stock powers) and otherwise
      in good form for delivery, against payment of the purchase price by the
      Company.

      7.3 Trust Liquidity Right. If, prior to the consummation of a Qualified
IPO, the most junior publicly traded debt security of the Company is
unconditionally rated (the "Rating") BBB- or higher by Standard & Poor's Rating
Group ("S&P") or Baa3 or higher by Moody's Investors Services, Inc. ("Moody's"),
the Trust may deliver a notice to HMTF and BSMB (the "Liquidity Notice")
requiring HMTF and BSMB for period of twelve (12) months after delivery of the
Liquidity Notice to use commercially reasonable efforts to assist the Trust in
consummating a Transfer of all of its Securities to Person. The obligation of
BSMB and HMTF under this Section 7.3 shall automatically terminate upon the
expiration of such twelve-month period. At any time during such twelve-month
period that the Rating has been placed under review or withdrawn by S&P or
Moody's, as the case may be, the Liquidity Notice shall be deemed to have been
automatically withdrawn by the Trust.

      7.4 Company Covenant. The Company agrees to use all reasonable efforts to
cause each Person who is obligated to become a party to this Stockholders'
Agreement after the Effective Date pursuant to the terms of his/her option
agreement to execute and deliver to the Company an Instrument of Accession in
the form of Exhibit A hereto.

<PAGE>   157
            (a) The provisions of this Stockholders' Agreement shall terminate
      on the tenth (10th) anniversary of the Effective Date; provided, however,
      that Sections 2.1, 2.3, 4.1, 4.2, 4.3, 4.4, 4.7, Article 5 (other than
      Sections 5.2 and 5.4), Article 6, Article 7 and Section 9.8 of this
      Stockholders' Agreement shall terminate upon the consummation, prior to
      the expiration of such ten (10) year period, of a Qualified IPO.

            (b) The provisions of this Stockholders' Agreement shall terminate
      with respect to any Holder at such time as such Holder no longer
      Beneficially Owns any Securities or PIK Preferred Stock of the Company.

      8.2 Termination of Certain Provisions. Sections 2.3 and 4.2 of this
Stockholders' Agreement shall terminate at the time at which the HMTF Group
ceases to Beneficially Own at least twenty-five and two-tenths percent (25.2%)

any other person (except as set forth in Section 3.8 or this Section 9.4) any
