manufactures pipe and duct insulation for use in commercial buildings,
factories, refineries and other industrial applications. In response to
industry attention to indoor environmental quality, Johns Manville offers
EnviroSystem(TM), a group of products sold together aimed at indoor
environmental quality improvement. Such products include duct insulation with
enhanced thermal and acoustical properties with an antimicrobial agent for
improved air filtration. In addition, through a joint venture in Canada, Johns
Manville offers fire protection products.

  Johns Manville manufactures commercial and industrial insulation products at
seven facilities in North America.

  Markets and Distribution. Demand for Johns Manville's commercial and
industrial insulation and fire protection products is driven primarily by
commercial construction activity and by demand in the remodel/retrofit market,

                                       2
<PAGE>

 OEM

  Products. Johns Manville's OEM insulation business produces thermal and
acoustic insulation for aircraft, marine vessels, automobiles, HVAC and other
equipment. OEM insulation products generally require extremely fine and
uniform fibers to provide the required insulating properties, and therefore
command higher prices than other fiber glass products.

  Johns Manville manufactures OEM insulation products at nine facilities in
the United States.

  Markets and Distribution. Demand for Johns Manville's OEM insulation
products is driven primarily by the production of aircraft, marine vessels and
automobiles and by commercial construction (for HVAC and other insulations).
Johns Manville typically sells OEM insulation products to distributors and
fabricators who, in turn, sell to original equipment manufacturers.

  Competition. Johns Manville's OEM insulation business competes with a
variety of large and small companies in its various niche markets. Johns
Manville competes in the OEM insulation business primarily on the basis of
price, quality and product customization.

Roofing Systems

  In 1999, Johns Manville's Roofing Systems segment had net sales of $606.5
million, or 28 percent of the Company's total net sales (before elimination of
intersegment sales).

  Products. Johns Manville is a full-line supplier of roofing systems and
components for low-slope commercial and industrial roofs, including a wide
range of membranes, insulations, accessories and roofing systems guarantees.

  Johns Manville's commercial/industrial roofing systems business operates 20
manufacturing facilities in the United States and has three additional plants
located in Altamira, Mexico; Cornwall, Ontario, Canada; and Verona, Italy.

  In September 1999, the Company purchased certain of the polyisocyanurate
foam insulation manufacturing facilities of Apache Products, Inc., ("Apache")
including plants located in Belvidere, Illinois and Anderson, South Carolina.
In addition, the Company entered into long term lease agreements for
facilities located in Riverside, California and Linden, New Jersey. As part of
the acquisition, the Company entered into a long term agreement to supply
Apache with polyisocyanurate foam insulation products.

  Markets and Distribution. Demand for Johns Manville's roofing systems
products is driven primarily by commercial and industrial reroofing needs.
Johns Manville estimates that approximately 75 percent of its roofing material
sales during 1999 were attributable to reroofing, with the balance
attributable to new construction. While sales of roofing systems are affected
by levels of new construction and general economic conditions, sales
attributable to reroofing are less sensitive to these factors, thus mitigating
the adverse effect of recessionary periods.

  Johns Manville's marketing focus is directed to roofing contractors and
distributors, building owners, architects and roofing consultants who
generally recommend premium roofing systems. Approximately 95 percent of Johns
Manville's roofing systems sales during 1999 were sold through wholesale
distributors; the remainder was sold through roofing contractors.

  Competition. The commercial and industrial roofing business is a highly
fragmented market. Competitors include several large national participants and
various smaller regional companies. Johns Manville competes in the commercial
and industrial roofing business primarily on the basis of breadth of product
line, specifications, guarantees, systems reliability and value.

Engineered Products

  Johns Manville's Engineered Products segment had 1999 net sales of $782.7
million, or 34 percent of Johns Manville's total net sales (before elimination
of intersegment sales). The Engineered Products segment is comprised of the
mats and fibers and filtration product groups.

 Mats and Fibers

  Products. Johns Manville's mats and fibers business manufactures mats and
fibers, glass fabrics and continuous filament fiber glass-based products that
are used in a variety of applications. Johns Manville is a worldwide supplier
of base fiber, nonwoven fiber glass and polyester spunbond mat products, which
are used as substrates in roofing, flooring and specialty applications and
monofilament used in the paper industry. Johns Manville also sells fiber glass
products (chopped fiber and rovings) for reinforcing plastics and gypsum
products and for use in fiber glass wall coverings.

  The mats and fibers business operates four manufacturing plants and one
support facility in the United States. Johns Manville's German subsidiaries
operate five plants in Germany, one plant in Poland and one plant in China.
Schuller GmbH was the pioneer in wet fiber glass mat technology and also
developed the unique silver fiber glass process, which created the market for
fiber glass wall coverings in Europe. Johns Manville's Mitex subsidiaries
operate two manufacturing facilities in Sweden and one in the United Kingdom.

  In January 1999, the Company acquired the Spunbond/Monofilament operations
of Hoechst's polyester business. The Company acquired five manufacturing
plants located in Spartanburg, South Carolina; Bobingen, Germany; Berlin,
Germany; Limavady, Northern Ireland and Quin Pu City, China.

  Markets and Distribution. Demand for Johns Manville's mats and fibers
products is driven primarily by the worldwide commercial construction and
retrofit markets, as well as by U.S. residential construction and reroofing
markets. Mats and fibers products are sold directly to roofing and flooring
manufacturers and to Johns Manville's Mitex subsidiaries as well as to other
European textile weavers. Johns Manville's U.S. mats and fibers business

media for commercial and industrial buildings for HVAC and other equipment and
ultra-fine fibers for clean room air filters. The Company also manufactures
liquid filtration cartridges and media for use in commercial and industrial
applications. As with OEM insulation, filtration products generally require
extremely fine and uniform fibers to provide the required filtration
properties, and therefore command higher prices than other fiber glass
products.

  The Company manufactures filtration products at five of Johns Manville's
U.S. facilities.

  Markets and Distribution. Demand for Johns Manville's filtration products is
driven primarily by commercial construction and commercial building occupancy
(air filtration media); the construction of clean rooms requiring dust-free
environments which are primarily used by the pharmaceutical and semiconductor
industries (ultra-fine fibers); and the need for high efficiency filtration of
water, paints, inks, chemicals, resins and oils in industrial manufacturing
operations (liquid filtration media). Increasing public attention to
environmental issues also stimulates demand for filtration media and
industrial oil sorbent products.

MATERIALS

  Fiber glass is the basic material in a significant number of Johns
Manville's products. The principal raw materials used to manufacture fiber
glass products include sand, soda ash, lime, borate minerals and aluminous
materials. Phenol-formaldehyde, urea extended phenol-formaldehyde, urea-
formaldehyde, melamine-formaldehyde and other resins are also used to bind
glass fibers. All of these raw materials are readily available in sufficient
quantities from various sources for Johns Manville to maintain and expand its
current production levels.

  Johns Manville's products contain materials other than fiber glass to
satisfy the broader needs of its customers. For example, calcium silicate pipe
insulation products and plastic accessories complement Johns Manville's
product offerings to commercial/industrial insulation customers.
Commercial/industrial roofing systems use perlite insulation board, modified
bitumen and single ply membranes with polyester substrates. In addition, the
Company uses several advanced polymers in roll goods. The Company manufactures
polyisocyanurate foam roof insulation and residential sheathing using liquid
chemicals comprised primarily of polyol and polyisocyanate. Johns Manville has
broadened its product lines into certain polymer fiber applications for
filtration, substrates, and equipment insulation, apparel and industrial oil
sorbents. The raw materials used in these various products are readily
available in sufficient quantities from various sources for Johns Manville to
maintain and expand its current production levels.

RESEARCH AND DEVELOPMENT

  The Company carries out research and development activities at its
facilities in Littleton, Colorado; Mesa County, Colorado; Waterville, Ohio;
Richmond, Indiana; Wertheim, Germany; and Helsingborg, Sweden. Research,
development and engineering expenses for the years ended December 31, 1999,
1998 and 1997 were approximately $39.8 million, $32.8 million and $31.2
million, respectively.

PATENTS

  The Company presently owns or controls 1,207 U.S. and foreign patents and
patent applications. The Company also holds negotiated licenses under various
patents owned by others. While the Company regards its patents and licenses as
valuable, it does not consider any of its businesses to be materially
dependent upon any single patent or license.

LABOR RELATIONS

  At December 31, 1999, the Company employed approximately 9,740 persons
worldwide, of whom approximately 4,475 were covered by collective bargaining
agreements. The Company has experienced a long history of good working
relationships with its employees and labor unions.

SEASONALITY

  The Company's quarterly results of operations are moderately seasonal due to
increases in construction activity that typically occur in the second and
third quarters of the calendar year, thereby increasing sales and gross
profits in those periods.

                                       5

Environmental Regulations

  All of the Company's domestic operations are subject to a variety of
federal, state and local environmental laws and regulations. These laws and
regulations regulate the discharge of materials into the air, land and water
and govern the use and disposal of hazardous substances. The most significant
of the federal laws are the Clean Air Act, the Clean Water Act, the Toxic
Substances Control Act, the Resource Conservation and Recovery Act ("RCRA")
and the Comprehensive Environmental Response, Compensation and Liability Act
of 1980 ("CERCLA"). These environmental regulatory programs are administered
by the federal Environmental Protection Agency ("EPA"). In addition, state and
local jurisdictions have adopted equivalent or more stringent environmental
laws and regulations, or have enacted their own parallel environmental
programs, which are enforced through various state and local administrative

Occupational Health and Safety Aspects of the Company's Products

  The Company manufactures, processes and sells products, and has in the past
manufactured, processed and sold products, that contain certain chemicals or
substances, including man-made mineral fibers (now referred to as synthetic
vitreous fibers ("SVF")), classified by the International Agency for Research
on Cancer ("IARC") in 1987 as possible human carcinogens. For purposes of
occupational exposure, the Occupational Safety and Health Administration
("OSHA") regulates all SVF as nuisance dusts. On May 18, 1999, OSHA removed
SVF (e.g., fiber glass, rock wool and slag wool) as a regulatory priority
based on the agreement by the Company and other fiber glass manufacturers to
adopt certain work practices and exposure limits at their facilities. The
Company believes that it is and has been in compliance with all applicable
workplace exposure regulations. In 2001 IARC will reconsider its 1987
classification of fiber glass as "possibly carcinogenic." This reconsideration
will take into account many recent peer-reviewed studies published since 1987
such as the U.S. epidemiology study (updated in 1990 and again in 2000) by
University of Pittsburgh researcher Dr. G. Marsh.

  Labels and other hazard communication materials reflecting the potential
cancer risk have been developed and are used by the Company to address the
proper handling of fiber glass wool products by employees and customers. In
addition, the Company has agreed to indemnify certain purchasers, under
certain circumstances, for personal injury claims arising out of exposure to
the Company's fiber glass wool products.

  Crystalline silica exists in trace amounts in the Company's calcium silicate
insulation products and is a major constituent of the diatomaceous earth
products produced by a former subsidiary and in industrial sands used in the
Company's direct melt operations, marble forming and roofing plants. In 1996,
the IARC classified crystalline silica as "known carcinogenic to humans."
Occupational exposures to crystalline silica within the Company's facilities
are documented and controlled through exhaust ventilation or personal
protective equipment. Products containing this substance comply with OSHA
hazard communication requirements.

  In addition, asphalt used by the Company's roofing operations presently is
being evaluated by the National Institute of Occupational Safety and Health to
determine its carcinogenic potential.

  Based upon its analysis to date, the Company does not believe that the IARC
classifications or any action taken by federal and state regulatory agencies
will have a material adverse effect on the Company. However the Company's
analysis of available data and its expectations concerning human health
hazards associated with its products are subject to risks and uncertainties.
Because domestic and international regulatory and scientific authorities are
involved on an ongoing basis in the assessment of potential human health
hazards, there can, therefore, be no assurance that future actions taken by
such authorities or other developments relating to the Company's liability for
its products will not have an adverse effect on the Company. The foregoing
statements constitute "forward-looking statements" under federal securities
laws.

                      TRANSITION AND RETIREMENT AGREEMENT
                      -----------------------------------

          This TRANSITION AND RETIREMENT AGREEMENT (the "Agreement") is entered
into as of the 3rd day of February, 2000, by and between JOHNS MANVILLE
CORPORATION, a Delaware corporation (the "Company"), and CHARLES L. HENRY (the
"Executive").

          WHEREAS, the Executive is currently employed by the Company as
Chairman of the Company's Board of Directors ("Chairman"), President and Chief
Executive Officer ("CEO") pursuant to an Employment Agreement dated as of
September 9, 1996, as amended as of April 1, 1998, between the Company and the
Executive (the "Employment Agreement"); and

          WHEREAS, Executive having decided to retire as Chairman, President and
CEO, the Company and Executive desire to enter into the following agreement in
settlement and cancellation, except as otherwise provided herein, of all
existing and prior agreements between them (including the Employment Agreement)
concerning Executive's employment by the Company; and

          WHEREAS, the Company desires to ensure a smooth transition of
Executive's duties and responsibilities, to recognize Executive's outstanding
leadership of the Company and to ensure Executive's continued contribution to
the Company during the Transition Period and the Post-Transition Period (as such
terms are hereinafter defined); and

          WHEREAS, the Executive is desirous of continuing to serve the Company
during the Transition Period and the Post-Transition Period on the terms and
conditions set forth herein;

          NOW THEREFORE, for good and valuable consideration, the receipt of
which is hereby acknowledged, the Company and the Executive hereby agree as
follows:

          1.   TRANSITION AND POST-TRANSITION PERIODS. (a) The Company shall
               --------------------------------------
     continue to employ the Executive, and the Executive shall continue to serve
     the Company, as Chairman, President and CEO, subject to the terms and
     conditions set forth in this Agreement, for a period (the "Transition

     the subsidiaries and affiliates of the Company.

          (b)  Without limiting Executive's duties and responsibilities as
     Chairman, President and CEO during the Transition Period, during the
     Transition Period and thereafter through July 31, 2000 (the "Post-

     with regard to management transition and succession (including, but not
     limited to, reasonably cooperating with the Company in the search for his

          Executive's compliance with his obligations under Section 1 hereof, be
          treated as a "Protected Termination" within the meaning of Section
          5(b) of the Deferred Stock Agreement, such that, as of the end of the
          Transition Period, one-twelfth of such deferred shares (or an
          aggregate of 3,922 deferred shares) shall vest for each whole or
          partial month subsequent to December 1999 during which the Transition
          Period remains in effect. The portion of such deferred shares which
          becomes so vested shall be payable in shares of common stock of the
          Company in accordance with the terms of the Deferred Stock Agreement.

               (B)  Stock Options.  For purposes of the various stock option
                    -------------
          agreements in effect between the Company and the Executive, the
          termination of Executive's employment at the end of the Transition
          Period shall, subject to Executive's compliance with his obligations
          under Section 1 hereof, be treated as a "Retirement," such that all
          outstanding stock options granted to Executive, to the extent fully
          vested and exercisable at the end of the Transition Period, shall
          remain exercisable until the first anniversary of the end of the
          Transition Period at which time such options shall expire and cease to
          be exercisable (or, in the event of Executive's failure to comply with
          such obligations, such options shall expire and cease to be
          exercisable three months following the end of the Transition Period,
          unless such failure is a basis for a termination for Cause, in which
          case such options shall expire and cease to be exercisable as of the
          date of Executive's termination of employment for Cause). All
          outstanding stock options granted to Executive, to the extent not
          fully vested and exercisable at the end of the Transition Period,
          shall be forfeited and canceled as of the end of the Transition
          Period. A schedule of vested and non-vested stock options, determined
          as of March 31, 2000, is annexed hereto as Exhibit A.

                    ---------------------------------
          Company's Deferred Compensation Plan (the "Deferred Compensation
          Plan"), the termination of Executive's employment at the end of the
          Transition Period shall be treated as a "Retirement", such that
          amounts credited, as of the end of the Transition Period, to
          Executive's Deferral Account under such Plan in the form of shares of
          common stock of the Company shall be treated as follows:

          which are attributable to the deferral of Executive's variable
          incentive

                                       4

          and (Y) 4,187.0659 shares credited to Executive's Deferral Account as
          of September 30, 1999, which represent "premium shares" attributable
          to the deferral of Executive's 1996 variable incentive award (the
          "1996 Premium Shares"), the Deferred Bonus Shares and the 1996 Premium
          Shares (together with any additional shares credited from October 1,
          1999 through the end of the Transition Period which are attributable
          to the reinvestment of dividend equivalents with respect to the
          Deferred Bonus Shares and the 1996 Premium Shares) shall be delivered
          to Executive in accordance with the terms of the Deferred Compensation
          Plan and the Executive's outstanding elections thereunder;

               (ii)   with respect to 8,402.3623 shares credited to Executive's
          Deferral Account as of September 30, 1999, which represent "premium
          shares" attributable to the deferral of Executive's 1997 variable
          incentive award (the "1997 Premium Shares"), the 1997 Premium Shares

          through the end of the Transition Period which are attributable to the
          reinvestment of dividend equivalents with respect to the 1997 Premium
          Shares) shall, subject to Executive's compliance with his obligations
          under Section 1 hereof, become vested and nonforfeitable as of the end
          of the Transition Period and shall be delivered to Executive in
          accordance with the terms of the Deferred Compensation Plan and the
          Executive's outstanding elections thereunder;

               (iii)  with respect to 8,916.9089 shares credited to Executive's
          Deferral Account as of September 30, 1999, which represent "premium
          shares" attributable to the deferral of Executive's 1998 variable
          incentive award (the "1998 Premium Shares"), the 1998 Premium Shares
          (together with any additional shares credited from October 1, 1999
          through the end of the Transition Period which are attributable to the
          reinvestment of dividend equivalents with respect to the 1998 Premium
          Shares) shall be forfeited and canceled as of the end of the
          Transition Period.

          Executive shall not make any election under the Deferred Compensation
          Plan to reallocate any amounts credited to his Deferred Account
          thereunder to any alternative investment vehicle.

               (4)    Retirement Benefits.  The Retirement Benefit (as defined
                      -------------------
          in the Employment Agreement) to which Executive shall be entitled upon
          his termination of employment at the end of the Transition Period
          shall be the Retirement Benefit determined pursuant to Section 6(c) of

                                       5
<PAGE>

          the Employment Agreement. An estimate of such Retirement Benefit as of
          March 31, 2000 (based upon certain assumptions as to discount rates)
          is attached hereto as Exhibit B. The actual Retirement Benefit
          determined pursuant to said Section 6(c) (including the lump sum
          equivalent thereof determined pursuant to Section 6(d) of the
          Employment Agreement) shall be computed by William M. Mercer
          ("Mercer"), consultants to the Company, at the Company's expense, as
          of the end of the Transition Period in accordance with the methodology
          utilized in said Exhibit B, except that, in determining present
          values, Mercer shall utilize the discount rate in effect at January
          31, 2000 (or such earlier date on which the Transition Period ends),
          as set forth in the footnote to said Exhibit B. Such calculation shall
          be performed by Mercer within ten days after the end of the Transition
          Period and shall be provided (with backup) to the Company and the
          Executive. So long as the appropriate discount rate has been utilized,
          such computation by Mercer shall be binding and conclusive on the
          parties hereto, except for mathematical errors. Executive's
          entitlement to the Retirement Benefit shall be subject to the
          provisions of Section 12(f)(ii) of the Employment Agreement. In
          accordance with Section 6(d) of the Employment Agreement, the amount
          of the Retirement Benefit hereunder shall be paid to Executive in a
          lump sum within five days after delivery of Mercer's final computation
          of the Retirement Benefit (but in no event prior to the effective date
          of the Release executed by the Executive, as contemplated by Section 5
          hereof).

               (5)  Additional Payment.  Subject to Executive's compliance with
                    ------------------
          his obligations under Section 1 hereof and subject to the provisions
          of Section 12(f)(ii) of the Employment Agreement, the Company shall
          pay the Executive an aggregate amount equal to the excess of (1) the
          lump sum equivalent (determined pursuant to Section 6(d) of the
          Employment Agreement) of the Retirement Benefit which would have been
          payable under Section 6(b) of the Employment Agreement (calculated as
          of the end of the Transition Period as if Executive were entitled to
          such Retirement Benefit) over (2) the lump sum Retirement Benefit
          payable pursuant to Section 3(a)(4) hereof (such excess being
          hereinafter referred to as the "Payment"). An estimate of the Payment
          as of March 31, 2000 (based upon certain assumptions as to discount
          rates) is attached hereto as Exhibit C. The actual amount of the
          Payment shall be determined by Mercer, at the Company's expense, in
          accordance with the methodology utilized in said Exhibit C, except
          that, in determining present values, Mercer shall utilize the discount
          rate in effect at January 31, 2000 (or such earlier date on which the
          Transition Period ends), as

                                       6
<PAGE>

          set forth in the footnote to said Exhibit C. Such calculation shall be
          performed by Mercer within ten days after the end of the Transition
          Period and shall be provided (with backup) to the Company and the
          Executive. So long as the appropriate discount rate has been utilized,
          such computation by Mercer shall be binding and conclusive on the
          parties hereto, except for mathematical errors. The portion of the
          Payment in excess of one million dollars ($1,000,000) shall be paid to
          Executive in a lump sum within five days after delivery of Mercer's
          final computation of the Payment (but in no event prior to the
          effective date of the Release executed by the Executive, as
          contemplated by Section 5 hereof). The remaining one million dollars
          ($1,000,000), together with interest thereon from the end of the
          Transition Period to the date of payment at the rate announced by Bank
          of America as its "prime rate" as in effect at January 31, 2000 (or
          such earlier date on which the Transition Period ends) (the "Prime
          Rate") (such one million dollars plus interest being referred to as
          the "Holdback Amount"), shall be paid to Executive, as soon as
          practicable following the end of the Post-Transition Period, unless a
          two-person committee (the "Committee") of Company directors,
          consisting of Messrs. Ernest Drew and Michael Hammes (or, in the event
          of the death or incapacity or resignation of either or both of such
          individuals, another Company director or directors acceptable to the
          Executive), shall have theretofore determined in good faith that the
          Executive failed to perform his obligations under Section 1 of this
          Agreement or materially failed to comply with the provisions of
          Section 12(c)(i) of the Employment Agreement. Any determination of
          nonpayment by the Committee shall be delivered in writing by the
          Committee to the Company and the Executive within fifteen (15) days
          after such determination is made (but in no event later than fifteen
          (15) days after the end of the Post-Transition Period) and shall
          specify with detail the reasons therefor. If the Executive challenges
          the Committee's determination, resolution of the dispute shall be by
          arbitration in accordance with Section 13(g) of the Employment
          Agreement. In the event that, prior to the end of the Post-Transition
          Period, the Company (to which actions of any director shall be
          attributed for purposes of Section 12(c)(ii) of the Employment
          Agreement, without otherwise limiting the meaning of such Section)
          materially breaches its obligations under Section 12(c)(ii) of the
          Employment Agreement, then the Company shall immediately pay the
          Holdback Amount to the Executive and such amount shall no longer be
          subject to any further risk of forfeiture. Any assertion by the
          Executive of any such breach by the Company shall be delivered in
          writing by the Executive to the Company and the Committee within
          fifteen (15) days after Executive has actual

                                       7
<PAGE>

          knowledge of the event or events giving rise to such assertion and
          shall specify in detail the basis therefor. If the Company challenges
          Executive's assertion as provided in the prior sentence, resolution of
          the dispute shall be by arbitration in accordance with Section 13(g)
          of the Employment Agreement, provided that, if Executive is successful
          in such arbitration, the Holdback Amount shall not be subject to
          forfeiture after the date of the Company's material breach of its
          obligations under Section 12(c)(ii) of Employment Agreement and the
          Holdback Amount shall become payable only after determination of the
          arbitrator (or, if earlier and the Executive otherwise qualifies to
          receive the Holdback Amount, promptly following the end of the Post-
          Transition Period).

               (6)  No Rights to Severance, etc.  Executive shall have no right
                    ----------------------------
          to receive (and the Company shall be under no obligation to pay) any
          severance, separation pay, salary continuation or similar benefits
          (including, but not limited to, the severance benefits set forth in
          Section 7(d)(i) of the Employment Agreement), nor shall Executive be
          entitled to receive (nor shall the Company be under any obligation to
          provide) any of the benefits contemplated by Sections 7(d)(ii),
          7(d)(iii) or 7(d)(v) of the Employment Agreement.

          (b)  In the event that, prior to the end of the Transition Period,
     Executive's employment is terminated by the Company for Cause (as defined
     in Section 7(c) of the Employment Agreement), or Executive voluntarily
     terminates his employment (other than for Good Reason, as defined in
     Section 7(e) of the Employment Agreement, except that (1) the actions
     contemplated by Section 1(a) hereof shall not constitute Good Reason) and
     (2) any claim by the Executive that Good Reason exists shall be based
     solely on acts or omissions occurring on or after the Effective Date),
     Executive's rights shall be limited to (1) his receipt of Base Salary,
     benefits and perquisites to the date of termination, (2) payment of the
     Retirement Benefit determined as of the date of termination pursuant to
     Sections 6(c) and 6(d) of the Employment Agreement, (3) treatment of
     Executive's vested and exercisable stock options in accordance with the
     parenthetical language in Section 3(a)(3)(B) hereof, and (4) such other
     payments and benefits as are determined in accordance with the terms of the
     applicable agreements (other than the Employment Agreement), plans,
     policies and practices of the Company.

          (c)  In the event that prior to the end of the Transition Period,
     Executive dies while in the employ of the Company, Executive's employment
     is terminated by the Company without Cause, or Executive voluntarily
     terminates his employment for Good Reason (as defined in paragraph (b)

                                       8
<PAGE>

     above), Executive shall be treated as if he had remained in employment
     until March 31, 2000, and the rights of Executive (or, in the event of his
     death, his beneficiary or estate) shall be as set forth in Section 3(a)
     above.

          (d)  Notwithstanding the preceding paragraphs (a) through (c) of this
     Section, in the event that, prior to the end of the Transition Period and
     while Executive is (or is deemed to be) in the employ of the Company, (1) a
     Change in Control (as defined in Section 8(g) of the Employment Agreement)
     shall occur or (2) a definitive agreement (a "Change in Control Agreement")
     is entered into by the Company consummation of the transaction contemplated
     by which would constitute a Change in Control, then (A) as of the date of
     such Change in Control (but in the case of a Change in Control described in
     clause (i) of Section 8(g) of the Employment Agreement which results from
     determining beneficial ownership without regard to the sixty day period
     referred to in Rule 13d-3 under the Securities Exchange Act of 1934 (a
     "Special Change in Control"), as of the date of consummation of the
     transaction contemplated by such Special Change in Control) but in any
     event not later than March 31, 2000, Executive's employment shall be deemed
     to have terminated under circumstances entitling him to the payments and
     benefits set forth in Section 8(d) (and, if applicable, Section 9(b) of the
     Employment Agreement, (B) Executive shall have no further obligations under
     Section 1 hereof after consummation of such Change in Control (or, in the
     event of a Special Change in Control or in the event of the Company enters
     into a Change in Control Agreement, after consummation of the transaction
     contemplated by such Special Change in Control or Change in Control
     Agreement), and (C) in lieu of the payments and benefits otherwise provided
     under this Agreement and subject to the succeeding provisions of this
     paragraph, Executive's rights shall be limited to receipt of the payments
     and benefits set forth in said Section 8(d) (and, if applicable, Section
     9(b), provided, however, that in the event of a Special Change in Control
           --------  -------
     or in the event the Company enters into a Change in Control Agreement, the
     Company's obligation to make or provide the foregoing payments and benefits
     shall apply only upon consummation of the transaction contemplated by the
     Special Change in Control or Change in Control Agreement (as the case may
     be) and in the event such transaction is abandoned or not otherwise
     consummated for any reason, then this paragraph (d) shall not apply and
     Executive's rights shall be determined pursuant to paragraph (a), (b) or
     (c) of this Section 3, whichever paragraph is applicable.  Notwithstanding
     the foregoing, pending consummation of any such transaction, the amounts
     and benefits to which Executive is otherwise entitled under paragraph (a),
     (b) or (c) of this Section 3 shall be paid or provided in accordance with
     the provisions of the applicable paragraph (and Executive shall be under no
     obligation to return any such amounts or benefits received to which he is
     otherwise entitled),

                                       9
<PAGE>

     subject to supplemental amounts and benefits being paid or provided by the
     Company under Sections 8(d) and 9(b) of the Employment Agreement upon
     consummation of such transaction, it being understood, however, that the
     Company shall be under no obligation to make payments or provide benefits
     under said Section 8(d) or 9(b) to the extent such payments or benefits are
     duplicative of payments or benefits theretofore made or provided to
     Executive hereunder. Further, nothing herein shall limit Executive's rights
     which arise under any Company plan or grant upon the occurrence of a Change
     in Control prior to the end of the Transition Period while Executive is in
     the employ of the Company.

          (e)  Executive shall not be deemed to have failed to comply with his
     obligations under Section 1 hereof, nor shall Executive be deemed to have
     voluntarily terminated his employment, solely by reason of Executive being
     unable to perform any obligations hereunder as a result of mental or
     physical incapacity. Further, such inability shall not serve as the basis
     for a termination for Cause hereunder.

          (f)  The Company may assert a violation by Executive of his
     obligations under Section 1 this Agreement only if such assertion has been
     approved by the Committee.

          4.   PUBLIC ANNOUNCEMENTS.  Executive and the Company shall cooperate
               --------------------
     with each other in the preparation and issuance of any press release or
     other public announcement pertaining to Executive's plans to retire.

          5.   RELEASE.  In connection with Executive's termination of
               -------
     Employment and as a condition to any payments or benefits hereunder,
     Executive or his personal or legal representative shall execute a Release,
     in the form of Exhibit D hereto.

          6.   SUCCESSORS.

          (a)  This Agreement is personal to the Executive and, without the
     prior written consent of the Company, shall not be assignable by the
     Executive otherwise than by will or the laws of descent and distribution.
     This Agreement shall inure to the benefit of and be enforceable by the
     Executive's estate and legal representatives.

          (b)  This Agreement shall inure to the benefit of and be binding upon
     the Company and its successors and assigns.

     related expenses incurred by him in connection with enforcing such rights,
     including the costs of arbitration, if and to the extent provided by the
     arbitral tribunal resolving such dispute, or if such dispute is resolved

     rights originally disputed by the Company. The Company shall pay
     Executive's reasonable legal fees (but not in excess of $30,000) incurred
     in connection with entering into this Agreement.

          9.   MISCELLANEOUS.

          (c)  No Waiver. The failure of a party to insist upon strict adherence
               ---------
     to any term of this Agreement on any occasion shall not be considered a
     waiver of such party's rights or deprive such party of the right thereafter
     to insist upon strict adherence to that term or any other term of this
     Agreement.

          (d)  Severability. It is expressly understood and agreed that although
               ------------
     Executive and the Company consider the restrictions contained in this
     Agreement to be reasonable, if a final judicial determination is made by a
     tribunal of competent jurisdiction that the time or territory or any other
     restriction contained in this Agreement is an unenforceable restriction
     against Executive, the provisions of this Agreement shall not be rendered
     void but shall be deemed amended to apply as to such maximum time and
     territory and to such maximum extent as such tribunal may determine or
     indicate to be enforceable. Alternatively, if any tribunal of competent
     jurisdiction finds that any restriction contained in this Agreement is
     unenforceable, and such restriction cannot be amended so as to make it
     enforceable, such finding shall not affect the enforceability of any of the
     other restrictions contained herein.  In the event that any one or more of
     the provisions of this Agreement shall be or become invalid, illegal or
     unenforceable in any respect, the validity, legality and enforceability of
     the remaining provisions of this Agreement shall not be affected thereby.

          (e)  Withholding Taxes.  The Company may withhold from any and all
               -----------------
     amounts payable under this Agreement such Federal, state and local taxes as
     may be required to be withheld pursuant to any applicable law or
     regulation.

          (f)  Counterparts.  This Agreement may be signed in several
               ------------
     counterparts, each of which shall be an original, with the same effect as
     if the signatures thereto and hereto were upon the same instrument.

          10.  SURVIVAL.  The respective rights of the parties and their
               --------
     successors and permitted assigns under the provisions of Sections 3, 7, 8
     and 9 hereof (and the associated provisions of the Employment Agreement
     referred to therein or incorporated herein by reference) shall survive the
     expiration of the Transition Period to the extent necessary to give effect
     to such provisions.

          IN WITNESS WHEREOF, the parties have executed this Agreement as of the

          (d)  Subject to Section 7(g), if during the Employment Term and prior
               to a Change in Control Executive's employment hereunder is
               terminated by the Company without Cause (other than by reason of
               death or

          7(e)(iv) below, the Base Salary as in effect prior to the reduction or
          reductions referred to therein plus the bonus Executive would have
          earned in respect of the year of termination under the Company's
          annual incentive compensation plan, if any, in effect at the date of
          termination or, in the event of a termination by Executive by reason
          of an event described in Section 7(e)(vi), the plan in effect prior to
          the elimination referred to therein, determined as if Executive had
          been employed by the Company for the full year and without regard to
          any right reserved by the Company to decrease or eliminate such bonus,
          and assuming actual performance had equaled 100% of the performance
          objective established for such year pursuant to the terms of such
          plan. In the event of a Change in Control following such termination,
          all remaining amounts then payable pursuant to this Section 7(d)(i)

          and (h) to read as follows:

          (g)  Notwithstanding any other provision of this Agreement, in

               the Company without Cause prior to a Change in Control pursuant
               to which payments are payable pursuant to Section 7(d) and (ii)
               such termination is the result of a Performance Related
               Termination Event (as defined in Section 7(g) below), then (x)
               the benefits and perquisites provided pursuant to Sections
               7(d)(ii) and 7(d)(iii) shall be provided for a 12-month period
               after such termination in lieu of a 24-month period, (y) the
               benefits and services provided pursuant to Sections 7(d)(iv) and
               7(d)(v) shall remain unchanged and (z) the amount payable
               pursuant to Section 7(d)(i) shall be reduced to the amount
               provided in Section 7(g)(i) below:

                    (i)  The Company shall pay Executive in equal monthly cash

                         following such termination and continuing on the fifth
                         day of each month thereafter for a period of 24 months,

                         fraction of the annual bonus which (absent such
                         termination and without regard to any right reserved by
                         the Company to decrease or eliminate such bonus)
                         Executive would have earned in respect of the year of
                         termination under the JM annual incentive compensation
                         plan, if any, in effect at the date of termination,
                         assuming actual performance had equaled 100% of the
                         performance objective established for such year
                         pursuant to the terms of such plan, the numerator of
                         which fraction is the number of days in such year
                         during which the Executive was employed by the Company
                         and the denominator of which is 365.

               (h)  For purposes of the foregoing, "Performance Related
                    Termination Event" shall mean Executive's failure to meet in
                    any material respect the expectations of the Company which
                    have been communicated to Executive and which are reasonable
                    and material in light of Executive's position after a
                    written notice specifying this Section and identifying such
                    failure is delivered to Executive and Executive shall have
                    failed during the 60-day period following such written
                    demand to have corrected such failure (other than as a
                    result of total or partial incapacity due to physical or
                    mental illness or as a result of termination by Executive
                    for Good Reason).

          6.   The lead-in paragraph of Section 8(d) of the Employment Agreement
               is hereby amended to read as follows:

               (d)  If during the Employment Term Executive's employment
               hereunder is terminated by the Company following a Change in
               Control without Cause (other than by reason of death or
               Disability) or by Executive with "Good Reason" (which following a
               Change in Control shall have the meaning set forth in Section
               8(e) below) asserted in a Notice of Termination pursuant to
               Section 13(f) within two years of the event alleged to constitute
               such Good Reason, Executive shall be entitled to receive the
               following benefits:

          7.   Section 8(d)(i) of the Employment Agreement is hereby amended to
               read as follows:

               (i)  The Company shall pay Executive at the time of termination
               in a lump sum a cash amount equal to three times the sum of (A)
               Executive's Base Salary in effect at the time of such termination
               or, in the event of termination by Executive by reason of an
               event described in Section 8(e)(iv) below, the Base Salary as in
               effect prior to the reduction or reductions referred to therein
               plus (B) the bonus Executive would have earned in respect of the
               year of termination under the Company's annual incentive
               compensation plan, if any, in effect at the date of termination
               or, in the event of a termination by Executive by reason of an
               event described in Section 8(e)(v), the plan in effect
               immediately prior to the reduction or reductions referred to
               therein, determined as if Executive had been employed by the
               Company for the full year and without regard to any right
               reserved by the Company to decrease or eliminate such bonus, and
               assuming actual performance had equaled 100% of the performance
               objective established for such year pursuant to the terms of such
               plan.

          8.   Section 9 of the Employment Agreement is hereby amended to read
               as follows:

               9.   Golden Parachute Tax.
                    --------------------

                    (a)  Anything herein to the contrary notwithstanding, in the
                    event that it is determined that any payment or distribution
                    by the Company to or for Executive's benefit, whether paid
                    or payable or distributed or distributable pursuant to the
                    terms hereof or otherwise, other than any payment pursuant
                    to this Section 9(a) (a "Payment"), would be subject to the
                    excise tax imposed by Section 4999 of the Internal Revenue
                    Code of 1986, as amended (the "Code") or any interest or
                    penalties with respect to such excise tax (such excise tax,
                    together with any such interest and penalties, are
                    hereinafter collectively referred to as the "Excise Tax"),
                    then Executive shall be entitled to receive, within 15 days
                    following the determination described in Section 9(b) below,
                    an additional payment ("Excise Tax Adjustment Payment") in
                    an amount such that after payment by Executive of all
                    applicable Federal, state and local taxes (computed at the
                    maximum marginal rates and including any interest or
                    penalties imposed with respect to such taxes), including any
                    Excise Tax, imposed upon the Excise Tax Adjustment Payment,
                    Executive shall retain an amount of the Excise Tax
                    Adjustment Payment equal to the Excise Tax imposed upon the
                    payments.

                    (b)  All determinations required to be made under this
                    Section 9, including whether an Excise Tax Adjustment
                    Payment is required and the amount of such Excise Tax
                    Adjustment Payment, shall be made by Coopers & Lybrand,
                    L.L.P. or such accounting firm as the Company may designate
                    prior to a Change of Control, which shall provide to the
                    Company and Executive detailed supporting calculations
                    within 15 business days of the date of Executive's
                    termination of Employment. Except as hereinafter provided,
                    any determination by Coopers & Lybrand, L.L.P. or such other
                    accounting firm as the Company may designate prior to a
                    Change of Control shall be binding upon the Company and
                    Executive. As a result of the uncertainty in the application
                    of Section 4999 of the Code at the time of the initial
                    determination hereunder, it is possible that (x) Excise Tax
                    Adjustment Payments which should have been made will not
                    have been made by the Company ("Underpayment"), or (y)
                    certain Excise Tax Adjustment Payments will have been made
                    which should not have been made ("Overpayment"), consistent
                    with the calculations required to be made hereunder. In the
                    event of an Underpayment, the Company shall promptly
                    determine the amount of the Underpayment that has occurred
                    and any such Underpayment shall be promptly paid by the
                    Company to or for Executive's benefit. In the event that
                    Executive discovers that an Overpayment shall have occurred,
                    the amount thereof shall be promptly repaid to the Employer.

          9.   The Employment Agreement is hereby amended to add, immediately
               prior to the first sentence of Section 13(d), the following:

               It is expressly understood and agreed that although Executive and
               the Company consider the restrictions contained in this Agreement
               to be reasonable, if a final judicial determination is made by a
               tribunal of competent jurisdiction that the time or territory or
               any other restriction contained in this Agreement is an
               unenforceable restriction against Executive, the provisions of
               this Agreement shall not be rendered void but shall be deemed
               amended to apply to such maximum time and territory and to such
               maximum extent as such tribunal may determine or indicate to be
               enforceable.

          10.  The Employment Agreement is hereby amended to add a new Section
               13(i), (j) and (k) to read as follows:

               (i)  Non-Disparagement. Executive and the Company shall each use
                    -----------------
                    all reasonable efforts not to make any statements or take
                    any action that may be derogatory or disparaging to the
                    reputation of the other or, in the case of the Executive, to
                    the reputation of any of the Company's

                                       5
<PAGE>

                    affiliates. Notwithstanding the foregoing, nothing in this
                    Agreement shall preclude either party from truthful
                    statements or disclosures that are required by applicable
                    law or regulation, or from taking any position in
                    prosecuting or defending any judicial, administrative or
                    arbitration proceeding arising hereunder.

               (j)  Cooperation.  Executive agrees that following termination of
                    -----------
                    Executive's employment with the Company prior to a Change in
                    Control for a period ending on the earlier to occur of the
                    fifth anniversary of such termination or a Change in
                    Control, Executive shall make himself reasonably available
                    to the Company and its legal counsel, taking into
                    consideration Executive's other obligations, and shall
                    cooperate with the Company in connection with any
                    litigation, investigation or other proceeding relating to
                    events occurring during Executive's employment hereunder or
                    facts as to which he has knowledge; provided that Executive
                                                        ---------
                    shall be entitled to reimbursement of necessary and
                    reasonable expenses incurred in connection therewith subject
                    to provision of receipts therefor and provided further that
                                                          -------- -------
                    (i) nothing herein shall require Executive to make any but
                    truthful statements and (ii) Executive will not be required
                    so to cooperate to the extent his position is in conflict
                    with that of the Company.

               (k)  Non-Competition/Non-Solicitation. (i) Executive acknowledges
                    --------------------------------
                    and recognizes the highly competitive nature of the business
                    of the Company and its affiliates and accordingly hereby
                    agrees, in consideration of the agreements herein of the
                    Company, that from the date hereof through the termination
                    of Executive's employment with the Company and, if such
                    termination occurs prior to a Change in Control, through the
                    two year period following such termination of Executive's
                    employment, (x) Executive shall not alone, or as a partner,
                    member, employee, agent, director, stockholder or investor
                    of any corporation or other business entity or in any other
                    individual or representative capacity, directly or
                    indirectly, own, manage, operate or control, or participate
                    in the ownership, management, operation or control of, or
                    work or provide consulting services to (including, without
                    limitation, without receiving a fee or other compensation),
                    or lend money to, any business, activity or person which
                    competes with a business or activity in North America,
                    Europe and Asia in which the Company is engaged or in which
                    the Company or its affiliates is actively and seriously
                    considering engaging at the time in question in the case of
                    conduct during such employment or at the time of Executive's
                    termination of employment in the case of conduct during such
                    two year period; provided the foregoing shall not prohibit
                                     --------
                    Executive from directly or indirectly making passive
                    investments of not more than one percent (1%) of the
                    outstanding equity interests in, or

                                       6

                    public debt of, any company or entity listed or traded on a
                    national securities exchange or an over the counter
                    securities market and (y) Executive shall not, directly or
                    indirectly, recruit, seek to recruit, or hire any present or
                    former employee of the Company or any of its subsidiaries
                    (level 30 or above) until at least one year has passed from
                    the date of termination of such person's employment with the
                    company or any of its subsidiaries.

                    (ii)   Executive hereby acknowledges that the business of
                    the Company and its affiliates is international in scope and
                    that, accordingly, any geographical limitation on the scope
                    of the foregoing covenant to less than that specified
                    therein could be meaningless, and that, by reason thereof,
                    Executive acknowledges that the scope of the foregoing
                    covenant is reasonable and necessary in order to protect the
                    interests of the Company and its affiliates sought to be
                    protected hereby.

                    (iii)  The parties acknowledge and agree that their
                    respective remedies for a breach or threatened breach of any
                    of the provisions of Section 13 (i), (j) or (k) would be
                    inadequate and, in recognition of this fact, the parties
                    agree that, in the event of such a breach or threatened
                    breach, in addition to any remedies at law, the aggrieved
                    party, without posting any bond, shall be entitled to obtain
                    equitable relief in the form of specific performance,
                    temporary restraining order, temporary or permanent
                    injunction or any other equitable remedy which may then be
                    available.

          11.  Except as provided by this Amendment, the Employment Agreement
               shall remain in full force and effect.

     IN WITNESS WHEREOF, the parties have executed this Amendment to be

1999 is entered into among Johns Manville Corporation, a Delaware corporation

     3.  Representations and Warranties.  The Company and JMII hereby represent
         ------------------------------
and warrant to the Agent and each Bank as follows:

         a.  The execution, delivery and performance by the Company and by JMII
of this Amendment have been duly authorized by all necessary action, including
any necessary authorizations by the board of directors of the Company and by the
board of directors of JMII and do not and will not require any registration
with, consent or approval of, notice to or action by, any Person (including any
Governmental Authority) in order to be effective and enforceable.

         b.  This Amendment and the Loan Documents to which the Company and/or
JMII is a party constitute the legal, valid and binding obligations of the
Company and/or JMII, as the case may be, enforceable against the Company and/or
JMII in accordance with their respective terms except to the extent that the
enforceability thereof may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or other similar laws affecting creditors' rights
generally or by equitable principles relating to enforceability.

         c.  The Company and JMII are each entering into this Amendment on the
basis of its own investigations and for its own reasons, without reliance upon
the Agent, the Banks or any other Person.

     4.  Effective Date.  This Amendment will become effective retroactively to
         --------------
May 15, 1998; provide that the Agent has received from the Company, JMII and all
of the Banks an executed counterpart of this Amendment and the Consent and
Agreement of Guarantors executed by each of the Guarantors.

     5.  Reservation of Right.  The Company and JMII each acknowledges and
         --------------------
agrees that the execution and delivery by the Agent and the Banks of this
Amendment shall not be deemed to create a course of dealing or an obligation to
execute similar waivers or amendments under the same or similar circumstances in
the future.

     6.  Miscellaneous.
         -------------

         a.  Except as expressly waived herein, all terms, covenants and
provisions of the Loan Documents are and shall remain in full force and effect.

         b.  This Amendment shall be binding upon and inure to the benefit of
the Company, JMII, the Agent and the Banks and their respective successors and
assigns. No third party beneficiaries are intended in connection with this
Amendment.

         c.  This Amendment shall be governed by and construed in accordance
with the law of the State of California.

         d.  This Amendment may be executed in any number of counterparts, each
of which shall be deemed an original, but all such counterparts together shall
constitute but one and the same instrument. Each of the parties hereto
understands and agrees that this Amendment (and any other document required
herein) may be delivered by any party thereto either in the

                                       2
<PAGE>

form of an executed original or an executed original sent by facsimile
transmission to be followed promptly by mailing of a hard copy original, and
that receipt by the Agent of a facsimile transmitted document purportedly
bearing the signature of the Company, JMII or any Bank will have the same force
and effect as the delivery of a hard copy original. Any failure by the Agent to
receive the hard copy executed original of such document shall not diminish the
binding effect of receipt of the facsimile transmitted executed original of such
document of the party whose hard copy page was not received by the Agent.

         e.  This Amendment contains the entire and exclusive agreement of the
parties hereto with reference to the matters discussed herein.  This Amendment
supersedes all prior drafts and communications with respect hereto or thereto.
This Amendment may not be amended except in accordance with the provisions of
Section 11.1 of the Credit Agreement.

         f.  If any term or provision of this Amendment shall be deemed
prohibited by or invalid under any applicable law, such provision shall be
invalidated without affecting the remaining provisions of this Amendment or the
Loan Documents.

         g.  The Company and JMII covenant to pay or reimburse the Agent, within
30 days after demand, for all reasonable costs and expenses incurred by the
Agent in connection with the development, preparation, negotiation, execution
and delivery of this Amendment.

                             [Signatures follow.]

               or any Subsidiary; and (ii) all taxes actually paid in connection
               with such sale or issuance."

     3.   Representations and Warranties.  The Company and JMII hereby represent
          ------------------------------
and warrant to the Agent and each Bank as follows:

          a.   The execution, delivery and performance by the Company and by
          JMII of this Amendment have been duly authorized by all necessary
          action, including any necessary authorizations by the board of
          directors of

                                       2
<PAGE>

          the Company and by the board of directors of JMII, and do not and will
          not require any registration with, consent or approval of, notice to
          or action by, any Person (including any Governmental Authority) in
          order to be effective and enforceable.

          b.   This Amendment and the Loan Documents to which the Company and/or
          JMII is a party constitute the legal, valid and binding obligations of
          the Company and/or JMII, as the case may be, enforceable against the
          Company and/or JMII in accordance with their respective terms except
          to the extent that the enforceability thereof may be limited by
          applicable bankruptcy, insolvency, reorganization, moratorium or other
          similar laws affecting creditors' rights generally or by equitable
          principles relating to enforceability.

          c.   The Company and JMII are each entering into this Amendment on the
          basis of its own investigations and for its own reasons, without
          reliance upon the Agent, the Banks or any other Person.

     4.   Effective Date.  This Amendment will become effective on November 30,
          --------------
1999; provided that the Agent has received from the Company, JMII and Majority
      --------
Banks an executed counterpart of this Amendment and the Consent and Agreement of
Guarantors executed by each of the Guarantors and the Company has paid an
amendment fee of 2 basis points to each consenting Bank based on such Bank's
Commitment.

     5.   Reservation of Rights.  The Company and JMII each acknowledges and
          ---------------------
agrees that the execution and delivery by the Agent and the Banks of this
Amendment shall not be deemed to create a course of dealing or an obligation to
execute similar waivers or amendments under the same or similar circumstances in
the future.

     6.   Miscellaneous.
          -------------

          a.   Except as expressly waived herein, all terms, covenants and
          provisions of the Loan Documents are and shall remain in full force
          and effect.

          b.   This Amendment shall be binding upon and inure to the benefit of
          the Company, JMII, the Agent and the Banks and their respective
          successors and assigns. No third party beneficiaries are intended in
          connection with this Amendment.

          c.   This Amendment shall be governed by and construed in accordance
          with the law of the State of California.

          d.   This Amendment may be executed in any number of counterparts,
          each of which shall be deemed an original, but all such counterparts
          together shall constitute but one and the same instrument. Each of the
          parties hereto understands and agrees that this Amendment (and any
          other document required herein) may be delivered by any party thereto
          either in

                                       3
<PAGE>

          the form of an executed original or an executed original sent by
          facsimile transmission to be followed promptly by mailing of a hard
          copy original, and that receipt by the Agent of a facsimile
          transmitted document purportedly bearing the signature of the Company,
          JMII or any Bank will have the same force and effect as the delivery
          of a hard copy original. Any failure by the Agent to receive the hard
          copy executed original of such document shall not diminish the binding
          effect of receipt of the facsimile transmitted executed original of
          such document of the party whose hard copy page was not received by
          the Agent.

          e.   This Amendment contains the entire and exclusive agreement of the
          parties hereto with reference to the matters discussed herein. This
          Amendment supersedes all prior drafts and communications with respect
          hereto or thereto. This Amendment may not be amended except in
          accordance with the provisions of Section 11.1 of the Credit
          Agreement.

          f.   If any term or provision of this Amendment shall be deemed
          prohibited by or invalid under any applicable law, such provision
          shall be invalidated without affecting the remaining provisions of
          this Amendment or the Loan Documents.

          g.   The Company and JMII covenant to pay or reimburse the Agent,
          within 30 days after demand, for all reasonable costs and expenses
          incurred by the Agent in connection with the development, preparation,
          negotiation, execution and delivery of this Amendment.

                             [Signatures follow.]

     IN WITNESS WHEREOF, the parties hereto have caused this Second Amendment to
Revolving Multicurrency Credit Agreement to be executed and delivered in Dallas,
Texas, by their duly authorized officers as of the day and year first written
above.

SELECTED FIVE-YEAR FINANCIAL DATA
- --------------------------------------------------------------------------------

Notes to Selected Five-Year Financial Data:

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

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

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

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

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

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

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

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

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

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

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

(I)  Pro forma data has been adjusted to eliminate the effects of nonrecurring
charges, certain pension plan settlement gains, gains on sales of equity
investments, mining royalty sale proceeds, interest expense on the 9 percent
Sinking Fund Debentures, profit sharing expense, an unusual 1996 income tax
item, discontinued operations, extraordinary losses, cumulative effect of
accounting change, preference stock dividends/accretion, and premium on
preference stock redemption, on a consistent basis and adjusted for estimated
applicable tax effects. In addition, earnings per share are based on 155.7
million and 161.9 million diluted weighted average shares for 1999 and 1998,
respectively, and 163.1 million pro forma diluted weighted average shares for
the other periods presented.

MANAGEMENT'S DISCUSSION AND ANALYSIS
- --------------------------------------------------------------------------------

Management's Discussion and Analysis of
Financial Condition and Results of Operations

Johns Manville Corporation ("JM") manufactures and markets building and
equipment insulation; commercial and industrial roofing systems; fibers, fabric
and nonwoven mats used as reinforcements in building and industrial
applications, and high efficiency filtration media. JM operates 58 manufacturing
facilities in North America, Europe and China, and is comprised of three
principal business segments: Insulation, Roofing Systems and Engineered
Products.

The Insulation segment consists of JM's building insulation business, which
manufactures fiber glass wool insulation for walls, attics and floors in
residential and commercial buildings; commercial and industrial insulation
business, which manufactures pipe and duct insulation for use in commercial
buildings, factories, refineries and other industrial applications; and original
equipment manufacturers ("OEM") insulation business, which manufactures thermal
and acoustic insulation for aircraft, marine vessels, automobiles and heating,
ventilating and air conditioning ("HVAC") and other equipment.

The Roofing Systems segment consists of JM's commercial and industrial roofing
systems business, which supplies built-up, modified bitumen and single-ply
membranes; perlite, fiber glass and polyisocyanurate foam insulations; roof
guarantees; and accessories.

The Engineered Products segment consists of mats and fibers, which includes base
fiber, fiber to reinforce gypsum wallboard and plastics, fiber glass and
polyester spunbond mats for roofing and flooring applications and monofilament
used in the paper industry; glass fabrics for wall coverings; and fiber glass
and synthetic media for high efficiency air filtration systems, face masks,
respirators, vacuum bags, sorbents and liquid filtration applications.
Filtration also produces fine fibers for specialty manufacturers who supply
filtration media for use in clean rooms and various battery separator
applications.

Consistent with JM's internal reporting, business segments discussed below
include allocated corporate expenses. The 1998 mining royalty sale proceeds are
reported in corporate and eliminations.

1999 vs 1998
Results of Operations

JM's net sales in 1999 increased $380.6 million, or 21.4 percent, to $2,161.8
million compared with $1,781.2 million in 1998. Gross profit increased $144.4
million to $621.6 million from $477.2 million. The gross profit margin for 1999
increased to 28.8 percent from 26.8 percent for 1998 due primarily to an
improved pricing environment and strong demand in building insulation, and
contributions from acquisitions. Selling, general and administrative and
research, development and engineering expenses, combined, increased $19.4
million in 1999 largely due to acquisitions. These expenses were lower as a
percentage of sales at 11.2 percent compared with 12.5 percent for 1998.

                               Johns Manville/15
<PAGE>

MANAGEMENT'S DISCUSSION AND ANALYSIS
- --------------------------------------------------------------------------------

Other expense, net, for 1999 was $26.6 million compared with other income, net,
of $25.9 million for 1998. Other expense, net, for 1999 reflects higher pension
expenses and higher goodwill amortization due to JM's acquisition program. Other
income, net, for 1998 reflects the proceeds of $36 million from a mining royalty
sale. Income from operations for 1999 was $352.2 million, up 44.5 percent,
compared with $243.7 million for 1998, excluding the royalty gain. Results of
operations for 2000 will be affected by 1999 equity market gains for pension
plan assets, positively impacting JM's pension expense (income).

Insulation Segment

Net sales for the Insulation segment increased $82.6 million, or 11.3 percent,
to $816.7 million for 1999 from $734.1 million for 1998. Income from operations
increased $66.2 million, or 56.1 percent, to $184.2 million compared with $118
million in 1998. Reflecting strength across JM's building insulation business,
these increases are due largely to improved selling prices and volume growth, as
JM operated at full capacity for most of 1999 due to favorable North American
residential and commercial construction markets. The selling price improvements,
along with volume increases, also led to strong 1999 margins. In commercial and
industrial insulation, higher gross profits on moderate net sales increases,
compared with 1998, reflected volume growth and higher selling prices in both
mechanical and OEM products.

Roofing Systems Segment

The Roofing Systems segment's net sales increased $44.7 million to $606.5
million in 1999 from $561.8 million in 1998, an 8 percent increase. Income from
operations for 1999 was $44.7 million, a 7 percent decline compared with $48
million for 1998. Acquisition-related sales increases were more than offset by
continued pricing pressures in polyisocyanurate foam insulation and roofing
membranes products.

Engineered Products Segment

Net sales for the Engineered Products segment increased $268.6 million, or 52.2
percent, to $782.7 million in 1999 compared with $514.1 million in 1998. Income
from operations in 1999 increased $45.7 million, or 58.7 percent, to $123.4
million from $77.7 million in 1998. The incremental impacts of JM's January 1,
1999 acquisition of Spunbond/Monofilament assets ("Monobond") produced
substantial increases in net sales and operating income. The U.S. mats and
fibers business experienced significantly higher sales in 1999 on volume growth
from increased demand in roofing mats, specialty mats and base fibers. While the
higher volumes drove the sales increase for this business, results were
adversely affected by costs associated with a scheduled furnace rebuild, which
was completed in the first quarter, and raw material cost increases. Meanwhile,
sales and operating income declined for European mats and fibers business during
1999, reflecting continued softness in Europe for most of the year, which
improved in the fourth quarter. Reduced demand and competitive pressures also
led to operating income declines for the European fabrics business. While sales
in the filtration business were flat for the year, volumes in the fourth quarter
were up significantly due to improvements in microfiber demand, particularly for
battery separators, and slight increases in clean room build activity.

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

Other Income (Expense), net

JM sold its 5 percent net smelter royalty on certain metals produced by the
Stillwater Mining Company for cash resulting in other income of $36 million in
the second quarter of 1998.

Interest Expense, net

Interest expense, net of interest income, decreased slightly to $29.1 million in
1999, from $29.5 million in 1998. Along with strong operating cash flows,
interest expense, net, was reduced by the 1998 repurchase of substantially all
of JM's $400 million of 10.875 percent Johns Manville International Senior Notes
due 2004 using revolving credit facilities with significantly lower interest
rates and the 1999 repayment of bonds payable to the Manville Personal Injury
Settlement Trust (the "Trust").

Income Taxes

JM's effective tax rate was approximately 19 percent in 1999 and 26 percent in
1998. JM receives a tax deduction and a related reduction in its effective tax
rate when the Trust pays claimants or makes distributions to a specific
settlement fund from dividends paid on, or proceeds received from disposition
of, JM stock held by the Trust. In both 1999 and 1998, JM benefited from such
distribution of dividends and stock sale proceeds to the settlement fund. In
addition, JM's 1999 income tax expense benefited from lower effective foreign
tax rates and adjustments to prior years' provisions.

Extraordinary Loss on Early Extinguishment of Debt

In June 1999 JM prepaid bonds payable to the Trust in the principal amount of
$23.9 million, resulting in a loss on the early extinguishment of debt of $5.8
million, net of taxes of $3.6 million. These bonds consisted of fixed payments
totaling $75 million per year in 2013 and 2014 and had been discounted at 13
percent.

During the second quarter of 1998 JM repurchased substantially all of its $400
million of 10.875 percent senior notes. The repurchase resulted in an
extraordinary loss on the early extinguishment of debt of $31.8 million, net of
taxes of $18.1 million.

Cumulative Effect of Accounting Change

Effective January 1, 1998 JM changed its method of accounting for glass furnace
rebuild costs to the capitalization method from the allowance method. The
cumulative effect of this change in accounting principle increased 1998 earnings
by $27.4 million, net of taxes of $17.9 million. This change resulted in an
increase in depreciation expense but eliminated the provision for furnace
rebuilds. The pro forma effect of this change on net income was not material.

Earnings Per Common Share

Basic and diluted net earnings per common share for 1999 were $1.66 and $1.64,
respectively, as compared with basic and diluted net earnings per common share
of $1.13 and $1.12, respectively, for 1998. The extraordinary losses on early
extinguishment of debt decreased basic and diluted earnings per common share by
$0.04 and $0.20 during 1999 and 1998, respectively. The cumulative effect of a
change in accounting principle increased basic and diluted earnings per common
share by $0.17 during 1998.

MANAGEMENT'S DISCUSSION AND ANALYSIS
- --------------------------------------------------------------------------------

1998 vs 1997
Results of Operations

JM's net sales for 1998 increased $133.6 million, or 8.1 percent, to $1,781.2
million compared with $1,647.6 million for 1997. Gross profit increased $45.7
million to $477.2 million from $431.5 million. The gross profit margin for 1998
increased to 26.8 percent from 26.2 percent due to volume and productivity gains
across all segments, partially offset by increased fixed costs and pricing
declines in the mats and fibers and filtration businesses. Selling, general and
administrative and research, development and engineering expenses, combined,
increased $17.6 million, or 8.6 percent, to $223.4 million and were flat as a
percentage of sales at 12.5 percent compared with 1997. Other income, net, was
$25.9 million for 1998 compared with other expense, net, of $10.3 million for
1997. Other income, net, for 1998 included proceeds of $36 million from a mining
royalty sale. Exclusive of the royalty gain, income from operations for 1998 was
$243.7 million, up 13.1 percent, compared with $215.4 million for 1997.

Insulation Segment

The Insulation segment's net sales increased $36.3 million, or 5.2 percent, to
$734.1 million in 1998 compared with $697.8 million in 1997. Income from
operations increased $31.4 million, or 36.3 percent, to $118 million compared
with $86.6 million in 1997. The 1998 results for building insulation reflect
volume increases due to strong demand, improved operating efficiencies and an
improved pricing environment, which began in the latter half of the year. While
commercial and industrial insulation businesses reflected moderately higher
sales volumes and selling prices for pipe and equipment insulation, gross
margins and operating income were negatively affected by downtime for equipment
upgrades during 1998. Also in 1998, the use of alternate materials resulted in
significantly lower sales and margins in automotive products.

Roofing Systems Segment

Net sales for the Roofing Systems segment increased $51.3 million, or 10.1
percent, to $561.8 million in 1998 compared with $510.5 million in 1997 due
primarily to incremental volume increases from thermoplastic membrane
acquisitions. Excluding the impact of acquisitions, net sales increased slightly
in 1998 compared with 1997. Income from operations, however, decreased to $48
million from $50.5 million in 1998 compared with 1997. Volume gains in 1998 were
partially offset by pricing pressures in polyisocyanurate foam products, a less
favorable product mix and acquisition-related costs. In addition, adverse
weather conditions early in the year limited roofing activity and shipments, and
negatively affected 1998 operating margins.

Engineered Products Segment

The Engineered Products segment's net sales increased $38.1 million, or 8
percent, to $514.1 million in 1998 compared with $476 million in 1997. Income
from operations decreased slightly to $77.7 million from $78.3 million for the
same periods. The sales increases are primarily due to the acquisitions of Mitex
and Tasso AB, both European manufacturers of fiber glass wall covering fabrics.
However, 1998 sales and operating income were adversely affected by slower
economic activity in Asia and Russia. Volume increases in the U.S. mats and
fibers business, net of the aforementioned weather-related declines in roofing
mat shipments, were partially offset by lower selling prices during 1998.
Results in filtration decreased in 1998 due to lower selling prices and a
worldwide slowdown in clean room builds.

                               Johns Manville/18

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

Other Income (Expense), net

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

Interest Expense, net

JM's interest expense, net of interest income, decreased $10.4 million, or 26.2
percent, to $29.5 million in 1998 compared with $39.9 million in 1997. This
decrease is primarily due to the repurchase of substantially all of JM's $400
million of 10.875 percent senior notes in 1998 using revolving credit facilities
with significantly lower interest rates. Also during 1998, JM used available
cash to repay borrowings under the revolving credit facilities.

Income Taxes

JM's effective tax rate was approximately 26 percent in 1998 and 1997. JM
benefited from the distribution of dividend and stock sale proceeds to the
settlement fund of the Trust and from the utilization of tax credits in both
years.

Discontinued Operations

During 1997 JM adjusted the estimated gain recognized in 1996 on the disposition
of Riverwood International Corporation. The adjustment, resulting in an
additional net gain on disposal of discontinued operations of $19.5 million,
arose from the expiration of certain indemnification obligations to the
purchaser of Riverwood and from the determination of certain income tax
consequences of the disposition, which were finalized with the completion of
JM's 1996 income tax returns.

Extraordinary Loss on Early Extinguishment of Debt

In 1998 JM repurchased substantially all of its $400 million of 10.875 percent
senior notes, resulting in an extraordinary loss on the early extinguishment of
debt of $31.8 million, net of taxes of $18.1 million.

Cumulative Effect of Accounting Change

The cumulative effect of the change in accounting for glass furnace rebuild
costs increased earnings by $27.4 million, net of taxes of $17.9 million, during
1998.

Earnings Per Common Share

Basic and diluted net earnings per common share for 1998 were $1.13 and $1.12,
respectively, as compared with basic and diluted net earnings per common share
of $0.93 and $0.92, respectively, for 1997. The extraordinary loss on early
extinguishment of debt decreased basic and diluted earnings per common share by
$0.20 during 1998. The cumulative effect of a change in accounting principle
increased basic and diluted earnings per common share by $0.17 during 1998. Gain
on disposal of discontinued operations increased basic and diluted earnings per
common share by $0.12 during 1997.

MANAGEMENT'S DISCUSSION AND ANALYSIS
- --------------------------------------------------------------------------------

Liquidity and Capital Resources

JM broadly defines liquidity as the ability to generate sufficient cash flow to
satisfy operating requirements, fund capital expenditures and meet existing
obligations and commitments. In addition, liquidity also includes the ability to
obtain appropriate financing and convert into cash those assets that are no
longer required to meet JM's strategic objectives. Therefore, liquidity should
not be considered separately from capital resources, which consist of currently
or potentially available funds for use in achieving long-range business
objectives and meeting debt service commitments.

JM's agreements with its lenders contain financial and general covenants. These
include, among other things, limitations on borrowings, investments and asset
dispositions and maintenance of various financial ratios. Noncompliance with
these or other covenants, or the occurrence of any other event of default, could
result in the termination of existing credit agreements and the acceleration of
debt owed by JM and its subsidiaries. At December 31, 1999 JM was in compliance
with these covenants.

JM's cash and marketable securities balances increased $48.3 million during 1999
to $64.8 million at December 31, 1999 from $16.5 million at December 31, 1998.
Total cash and marketable securities located outside the U.S. and Canada were
$20.2 million. At December 31, 1999 JM had approximately $458 million available
under its $750 million unsecured multicurrency revolving credit facilities. JM's
international subsidiaries had additional borrowing and working capital
facilities totaling $19.4 million, of which $12.8 million was available at
December 31, 1999. These facilities are principally secured by certain
receivables and cash of JM's international subsidiaries.

JM's net operating activities provided $468.4 million of cash during 1999,
offset by the premium on the prepayment of bonds payable to the Trust. Operating
activities for 1998 provided $226.3 million of cash, including the gain from the
sale of the Stillwater mining royalty, partially offset by the premium on the
prepayment of the 10.875 percent senior notes. Operating activities for 1997
provided $168.7 million of cash. Cash flows from operating activities are
primarily influenced by selling prices, sales volume and working capital
requirements. As discussed in "Results of Operations," JM benefited from selling
price improvements in building insulation, contributions from acquisitions and
volume increases during 1999. Cash provided by operations during 1999 also
benefited from improved working capital management.

JM's investing activities used $158.7 million in 1999, $391.1 million during
1998 and $213.4 million during 1997. Investing activities for 1999 used $152.9
million for capital expenditures, principally to increase building insulation
capacity and to complete a furnace rebuild for mats and fibers. The 1999 capital
expenditures included approximately $60 million related to capacity expansion
projects. Cash used for investing activities in 1998 included acquisitions of
$92.2 million, net of cash acquired, and capital expenditures totaling $106.4
million, of which approximately $46 million related to capacity expansion
projects. Investing activities for 1998 also included JM's $227.3 million
deposit for the Monobond acquisition completed in 1999. Cash used in investing
activities for 1997 included acquisitions of $136.5 million, net of cash
acquired, and capital expenditures totaling $90.5 million, of which
approximately $50 million related to capacity expansion projects. Investing
activities for 1997 also included proceeds from the disposition of JM's
automotive molded parts business.

                               Johns Manville/20
<PAGE>

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

JM's financing activities for 1999 consisted of issuances of debt totaling
$212.8 million, and repayments of debt totaling $275.7 million, net. In July
1999 JM issued $200 million of unsecured senior notes to certain institutional
investors in a private debt offering in two tranches: $75 million at 7.71
percent due in 2006; and $125 million at 7.92 percent due in 2009. A portion of
the proceeds were used to finance the purchase of 12.2 million shares of JM's
common stock from the Trust at $13.675 per share, resulting in the recognition
of treasury stock, at cost, of $166.8 million in the third quarter of 1999. The
remaining proceeds were used to repay existing indebtedness including prepayment
of $23.9 million of bonds payable to the Trust discussed above. JM also repaid
$12.5 million of debt assumed in an acquisition in 1999. In December 1999 JM
called the remaining $2.5 million of 10.875 percent senior notes due 2004. The
aforementioned 1999 debt activity also included issuances of $9 million and
repayments of $16 million under foreign credit facilities. JM paid dividends
totaling $37.5 million, $28.8 million and $21 million during 1999, 1998 and
1997, respectively. JM's financing activities for 1998 reflected repayments of
debt totaling $425.9 million and issuances of debt totaling $540.3 million, net,
relating primarily to the second quarter repurchase of its 10.875 percent senior
notes. Also in 1998 JM purchased 3.6 million shares of its common stock from the
Trust at $13 per share, and recognized treasury stock, at cost, of $46.8
million. During 1997 JM repaid debt totaling $30 million assumed in connection
with 1996 acquisitions. JM also borrowed $55 million from international credit
facilities to partially finance 1997 acquisitions, of which $10 million was
repaid in 1997. The remainder was repaid in 1998.

JM believes that its current cash position, funds available under credit
facilities and cash generated from operations will enable it to satisfy its debt
service requirements, its ongoing capital expansion program and its other
ongoing operating costs. However, JM may need to access capital markets to pay
the principal of its credit facilities and senior notes, or in connection with
possible significant future acquisitions.

Cyclicality of Demand/Competitive Environment

Demand for JM's products has historically been cyclical due to macroeconomic
factors affecting residential and commercial construction markets. Due to their
specific market niches, JM's roofing systems used for replacement, and
filtration and specialty products are less sensitive to business cycles. Selling
prices are subject to factors influenced by the competitive environment in which
JM operates, including fluctuations in overall capacity utilization.

Income Taxes

The cash taxes paid by JM in the U.S. were substantially lower than statutory
rates due to JM's deductions related to payments made to the Trust and tax
credit carryforwards. JM receives a tax deduction for the amount of any
dividends paid on shares of JM's common stock held by the Trust. In addition, JM
receives a tax deduction when the Trust sells some or all of its shares of JM
common stock and distributes the proceeds to its beneficiaries or transfers the
proceeds to a specific settlement fund.

MANAGEMENT'S DISCUSSION AND ANALYSIS
- --------------------------------------------------------------------------------

As of December 31, 1999 JM will need a cumulative total of approximately $520
million of U.S. federal taxable income to realize its net U.S. deferred tax
asset of $182.2 million. Based on JM's historical earnings levels, projected
future earnings and the expected timing of the taxable deductions principally
related to amounts paid by the Trust or transferred to a specific settlement
fund, JM believes it will realize its net deferred tax asset. JM estimates that,
as of December 31, 1999, $10.2 million of the gross deferred tax asset may not
be realized. This amount relates to remaining foreign tax credit carryforwards
that may expire unused. Accordingly, a full valuation allowance has been
provided for these amounts. The valuation allowance on JM's deferred tax asset
is subject to change as forecasts of future years' earnings and the estimated
timing of the utilization of JM's tax benefits and credit carryforwards are
revised, including actions by the Trust with respect to its ownership of JM
stock.

If the Trust were to sell its JM stock at a price greater than JM's carrying
value, JM may receive a tax benefit in excess of the deferred tax asset
reflected for financial reporting purposes. Likewise, if the Trust were to sell
the stock at a price lower than the carrying value, JM would receive a tax
benefit less than the deferred tax asset reflected for financial reporting
purposes. To illustrate, using the December 31, 1999 closing market price of
$13.9375 per share, the deferred tax asset related to JM's stock held by the
Trust would total approximately $550 million, which exceeds the carrying value
by nearly $415 million.

Under Section 468B of the U.S. Internal Revenue Code, JM is responsible for
income taxes on the taxable income of the Trust's specific settlement fund at a
tax rate of 15 percent. Any such taxes paid by JM will generate a tax deduction
for JM. JM cannot predict the amount of any such future tax obligations.
However, related liabilities could become material in certain situations
including the Trust monetizing, and retaining the proceeds of, a significant
portion of its investment in JM's common stock or the settlement of this
obligation between JM and the Trust. During 1999 and 1998 JM incurred
approximately $4.2 million and $3 million of these taxes, respectively, before
any U.S. federal or state benefit.

Capital Spending and Capacity Expansion

JM estimates capital spending in 2000 of approximately $178 million excluding
acquisitions, of which approximately $109 million will be used in capacity
expansion programs. During the third quarter of 1999, JM began construction on a
new two-module fiber glass insulation line to expand production capacity at its
Winder, Ga. facility. JM anticipates that one module will become operational
during the third quarter of 2000, with the second completed during 2002. Also
during the third quarter of 1999, JM began a capacity expansion at its Etowah,
Tenn. facility for mats and fibers, which is expected to become operational mid-
2000. As of December 31, 1999 outstanding purchase commitments relating to
capital spending and capacity expansion projects totaled $44 million. JM plans
to fund its capital spending from available cash balances and cash flows
generated by operations. JM's capacity expansion programs are periodically
revised to reflect changes in demand, industry capacity and the results of
productivity improvements and technological innovations.

In response to the implementation of the 1990 Amendments to the federal Clean
Air Act and requirements of various state air emissions regulations, JM may be
obligated to further monitor and reduce air emissions at its manufacturing
sites. The Title III air toxics regulations applicable to JM's fiber glass
plants were issued in proposed form in 1997. Subsequent proposed amendments to
those regulations in the first quarter of 1999 did not change the substantive
requirements related to air toxics. JM does not anticipate significant
compliance costs as a result of these regulations. Because the other anticipated
regulations have not yet been proposed, neither the costs nor timing of
compliance can be reasonably anticipated at this time, however, these
anticipated regulations could require capital expenditures in 2000 and 2001.

Acquisitions

On January 1, 1999 JM completed the Monobond acquisition. This acquisition
expands existing product lines of JM's Engineered Products segment in North
America, Europe and China. The cash payment for this acquisition, accounted for
under the purchase method, was $227.3 million, financed with borrowings from
JM's credit facilities. The acquisition borrowings, drawn during December 1998,
were shown as the acquisition deposit on the December 31, 1998 balance sheet.
During 1999 the allocated purchase price was adjusted to $209 million,
reflecting adjustments for preacquisition and purchase price contingencies.

On September 2, 1999 JM acquired certain polyisocyanurate roofing insulation and
sheathing foam business operations. In connection with this acquisition, JM
assumed, and subsequently repaid, $12.5 million of debt. This acquisition
complements existing JM product lines and is accounted for under the purchase
method.

Contingent Product Liability

Between 1988 and 1992 JM manufactured phenolic roofing insulation which may,
under certain circumstances, contribute to the corrosion of metal decks on which
it is installed. Since 1993 JM has had a program to voluntarily inspect such
metal decks and remediate where appropriate. JM has accrued for costs relating
to future inspections, remediation and anticipated claims. These accruals are
based on JM's historical experience regarding the incidence of corrosion and the
cost of remediation and include a number of assumptions related to the types and
remaining expected lives of roofs on which phenolic insulation has been
installed. Further, these accruals reflect JM's recent experience and
expectations for the future inspection and remediation program.

Pursuant to reimbursement agreements with JM's liability carriers and the former
owner of the phenolic roofing insulation business, JM is entitled to receive
reimbursement for a substantial portion of future costs to be incurred by JM for
inspection and remediation.

In 1996 JM and a third party were named as defendants in two class action cases,
now consolidated, filed in U.S. District Court in Boston, Mass. The plaintiffs
purport to represent all building owners in the U.S. with phenolic insulation
installed on their roof decks and seek damages and injunctive relief, including
an order requiring the removal and replacement of the phenolic insulation and
remediation of any deck corrosion. JM has reached a conditional agreement in
principle with respect to the settlement of these cases.

JM has reviewed its historical inspection and remediation experience, its
expectations for the future inspection and remediation program, the terms and
collectibility of amounts under the reimbursement agreements, and the terms and
probability of concluding the conditional settlement agreement in principle
discussed above. Based on the information available to date and subject to the
assumptions described above, if additional costs are incurred in excess of the
accrued and reimbursable amounts, such costs are not expected to have a material
adverse effect on JM's financial condition, liquidity or results of operations.

MANAGEMENT'S DISCUSSION AND ANALYSIS
- --------------------------------------------------------------------------------

Environmental Contingencies

At December 31, 1999 JM had remediation activities in progress at four sites,
out of a total of 15 such sites for which JM has identified environmental
conditions requiring remediation. In addition, JM has been identified as a
potentially responsible party at 13 non-Company owned or operated sites under
the federal Comprehensive Environmental Response, Compensation and Liability Act
("CERCLA") or similar state legislation. Of these 13 sites, JM's potential
liability for 11 sites will be determined pursuant to a global CERCLA order (the
"Order") described in the following paragraph. Two of the sites may not be
subject to the Order and, accordingly, JM could be jointly and severally liable
for costs of remediating these sites. However, both sites have multiple
potentially responsible parties working with the regulatory agencies. In
addition, JM's disposal percentage is at or near the de minimis level at both
sites. During 1999 JM settled its CERCLA and Resource Conservation and Recovery
Act ("RCRA") liability at three sites under the Order, of which one is final.

In 1994 the U.S. government and JM settled certain litigation concerning JM's
disposal activities prior to consummation of its plan of reorganization. The
Order, which was made a court order, limits JM's future liability under both
CERCLA and RCRA to 55 percent of its share of site-wide response costs and
natural resources damages without regard to joint and several liability for
disposals made by JM prior to consummation of JM's plan of reorganization. The
Order resolved JM's liability at certain historical sites and also covers CERCLA
and RCRA liability for other disposal sites at which the U.S. Environmental
Protection Agency ("EPA") has incurred or may incur response costs and which
were used by JM prior to consummation of the plan of reorganization. The Order
provides that the amount JM will be obligated to pay, in the aggregate, for such
sites shall never exceed $850,000 during any given year. The EPA and others from
time to time commence cleanup activities at such sites and in the future the EPA
and others may assert claims against JM with respect to such sites. JM believes
that all such activities and claims, if any, will be subject to the Order.

At December 31, 1999 and 1998 JM's balance sheet included undiscounted accruals
for environmental remediation costs, including ongoing compliance, maintenance
and monitoring costs, of $31.1 million and $34.8 million, respectively. JM paid
$3.9 million and $1.7 million for environmental cleanup in 1999 and 1998,
respectively. JM believes that amounts paid in 1999 are representative of JM's
2000 environmental cleanup costs. JM further anticipates expenditures relating
to costs currently accrued to be made over approximately the next 15 years.

In addition, JM's December 31, 1999 balance sheet included a liability of $21.9
million related to the demolition and restoration of a previously closed
manufacturing facility. JM spent $0.6 million in 1999 and expects to spend
approximately $7.1 million in 2000, pending federal and state regulatory agency
approval. The demolition and restoration is expected to be completed in 2002,
with the majority of the liabilities settled by that time.

As a result of factors such as changes in federal and state regulations, the
application and effectiveness of remedial actions, the difficulty in assessing
the extent of environmental contamination, and the allocation of costs among
potentially responsible parties, actual costs to be incurred for environmental
cleanup may vary from previous estimates. Subject to the uncertainties inherent
in evaluating environmental exposures, and based on information presently
available, including JM's historical remediation experience, currently enacted
environmental laws and regulations, the Order and existing remediation
technology, JM believes that if additional costs are incurred in excess of the
accrued amounts, such costs are not expected to have a material adverse effect
on JM's financial condition, liquidity or results of operations.

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

Year 2000 Compliance

JM engaged in a comprehensive project to modify its systems for year 2000
compliance. To date, JM has not incurred any significant problems related to
year 2000. JM spent $3.6 million on year 2000 projects and activities through
December 31, 1999.

Introduction of the Euro

On January 1, 1999, 11 countries of the European Union established a new single
European currency (the "Euro"). The Euro will become a currency in its own right
and will completely replace the currencies of the participating countries by
2002. This conversion may affect, among other things, cross-border competition
among member countries, product pricing, exchange rate risk and derivatives
exposure, and information technology and systems. JM's European businesses,
primarily in the Engineered Products segment, accounted for approximately 16
percent of total sales during 1999. JM is addressing issues related to the
conversion and, at this time, is not expecting material adverse effects on its
financial condition, liquidity or results of operations.

New Accounting Pronouncements

In June 1998 the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities." This statement, along with Statement of Financial
Accounting Standards No. 137, "Accounting for Derivative Instruments and Hedging
Activities - Deferral of the Effective Date of FASB Statement No. 133 - an
amendment of FASB Statement No. 133" issued in July 1999, is effective for all
fiscal quarters of fiscal years beginning after June 15, 2000 and establishes
accounting and reporting standards for derivative instruments and for hedging
activities. It requires that JM recognize all derivatives as either assets or
liabilities in the statement of financial position and measure those instruments
at fair value. At this time, JM cannot determine the effects, if any, adopting
this statement will have on its financial condition presentation or results of
operations.

Market Risk

JM is exposed to, among other things, the impact of interest rate changes,
foreign currency fluctuations, and changes in commodity prices related to
energy. JM is also exposed to political and related economic risks associated
with certain of the countries in which it operates. JM employs established
policies and procedures to manage its exposure and minimize volatility in
earnings and cash flows, lower costs and protect the value of certain foreign
currency denominated assets, liabilities and anticipated transactions. To
achieve these objectives JM enters into interest rate swaps to manage net
exposure to interest rate changes related to its debt obligations, foreign
currency contracts that change in value as foreign exchange rates fluctuate and
contracts to purchase certain quantities of goods at fixed prices. It is JM's
policy to enter into these derivative transactions only to the extent necessary
to meet the objectives stated above. Consequently, JM does not enter into these
transactions for speculative purposes.

Based on a one percentage point increase in applicable interest rates, the
hypothetical pretax loss in earnings on an annual basis related to JM's debt and
derivative financial instruments subject to interest rate risk at December 31,
1999 would be approximately $2 million. At December 31, 1999 JM had interest
rate swap transactions with notional values totaling approximately $99 million.
At December 31, 1999 JM did not have any significant outstanding forward
exchange or commodity contracts.

Forward-Looking Statements

This report contains "forward-looking statements" within the meaning of the
Private Securities Litigation Reform Act of 1995. Statements of JM contained in
this report concerning matters that are not historical facts, including, without
limitation, statements concerning:

 .    the ability to realize its net deferred tax asset,

 .    expectations related to the start of operations for the capacity expansions
     at its Winder, Ga. and Etowah, Tenn. facilities,

 .    expected levels of capital spending,

 .    expectations as to contingencies related to taxes, phenolic roofing
     insulation and environmental liabilities,

 .    expectations regarding the Euro conversion, and

 .    the ability to satisfy its debt service requirements, its ongoing capital
     expansion program and its other ongoing operating costs,

constitute such forward-looking statements. See "Liquidity and Capital
Resources."

Forward-looking statements of JM are subject to risks and uncertainties that
could cause actual results to differ materially from those expressed in such
statements. Important factors relating to such risks and uncertainties are set
forth below.

Factors that could affect the forward-looking statements generally are related
to demand for JM's products and to overall capacity levels in the industry.
Demand for such products is generally cyclical and is influenced by
macroeconomic factors that affect demand in residential and commercial
construction and replacement markets and demand from original equipment
manufacturers, including the general rate of inflation, interest rates,
employment rates and overall consumer confidence. Approximately 75 percent of
JM's annual sales are made to customers in commercial and industrial markets,
while the remainder are to residential construction markets.

Overall capacity levels in the industry directly affect prices and the need for
capacity for JM's products. Other factors that may affect prices and capacity
levels include the overall competitive environment in which JM operates, the
availability and pricing of raw materials, rates of technological development
and changes in productivity. In addition, overall demand for JM's products could
be affected by the factors described in "BUSINESS - Occupational Health and
Safety Aspects of the Company's Products" in JM's Annual Report on Form 10-K for
the year ended December 31, 1999. Capacity expansion is also subject to
construction and permitting risks.

Factors relating to JM's net deferred tax asset are discussed in "Liquidity and
Capital Resources-Income Taxes." For a discussion of factors concerning
contingencies related to taxes, phenolic roofing insulation, environmental
matters and the introduction of the Euro, see "Results of Operations - Income
Taxes" and "Liquidity and Capital Resources-Contingent Product Liability,
Environmental Contingencies, and Introduction of the Euro."

Other factors also could affect JM's expected levels of capital spending and
funding of current operations, debt service and dividends, including, without
limitation, the contingencies and commitments discussed in JM's financial
statements included in this report for the year ended December 31, 1999.

Notes to Consolidated Financial Statements
- --------------------------------------------------------------------------------

Note 1:
Summary of Significant Accounting Policies

Johns Manville Corporation ("JM") manufactures and markets building and
equipment insulation; commercial and industrial roofing systems; fibers, fabric
and nonwoven mats used as reinforcements in building and industrial
applications, and high efficiency filtration media. JM estimates that
approximately 75 percent of its annual sales are to commercial and industrial
markets, while the remainder are to residential construction markets. JM's
products are sold to contractors, mass merchants, wholesale distributors and
fabricators throughout North America, Europe and Asia.

The Manville Personal Injury Settlement Trust (the "Trust") owns approximately
76 percent of JM's common stock.

(A)  Principles of Consolidation

The consolidated financial statements include the accounts of JM and its
majority-owned subsidiaries. All significant intercompany transactions have been
eliminated.

(B)  Use of Estimates

The preparation of JM's consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the amounts reported in these financial statements,
including disclosures of contingent liabilities.

(C)  Cash and Equivalents

Cash and equivalents include money market mutual funds, time deposits and
marketable securities with original maturities of three months or less.

Included in accounts payable and compensation and employee benefits are
temporary book overdrafts totaling $30 million and $3.9 million, respectively,
at December 31, 1999; and $27.5 million and $3.2 million, respectively, at
December 31, 1998; due to JM's use of zero-balance cash disbursement accounts
funded by separate master accounts.

(D)  Financial Instruments

JM uses the amortized cost method of accounting for investments in held-to-
maturity debt securities for which it has the positive intent and ability to
hold to maturity. Fair value accounting is used for debt securities that are
classified as available-for-sale securities. Realized gains and losses are
computed on the specific identification method.

Gains and losses on foreign currency transactions and related forward exchange
contracts are included in other income (expense), net, for the period in which
the exchange rate changes. The discount or premium on forward contracts is
accounted for separately from the gain or loss on the contracts and is amortized
to other income (expense), net, over the life of the contract.

Amounts related to interest swap transactions qualifying for hedge accounting,
payable or receivable, are accrued on a current basis as adjustments to interest
expense. Any gains (losses) on the termination of the interest rate swaps are
deferred and recognized over periods corresponding to the related obligation
being hedged.

(E)  Inventories

Inventories are stated at the lower of cost or market. Cost is determined
principally on the last-in, first-out (LIFO) basis for all domestic
subsidiaries. The first-in, first-out (FIFO) basis is used to determine the cost
of inventories for all foreign subsidiaries.

(F)  Property, Plant and Equipment

Property, plant and equipment are stated at cost. Depreciation expense is
computed using the straight-line method, based upon the estimated useful lives
of the assets. Buildings are depreciated principally over 20 to 40 years, and
machinery and equipment are depreciated principally over 20 years. JM evaluates
the recoverability of property, plant and equipment through its ongoing
strategic planning process.

Maintenance and repairs are charged to current period earnings, while
replacements and betterments are capitalized.

                               Johns Manville/32
<PAGE>

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

JM capitalizes the cost of certain internally and externally developed computer
software. These capitalized costs, included in other assets, are amortized over
three to seven years, using the straight-line method.

(G)  Goodwill

Goodwill associated with acquisitions in excess of fair value of net assets
acquired is amortized on a straight-line basis generally over 20 years. JM
evaluates the recoverability of goodwill through its ongoing strategic planning
process.

(H)  Revenue Recognition

JM recognizes revenue from product sales upon shipment. JM estimates and records
provisions for cash discounts, customer incentives, sales returns, allowances
and original warranties in the period the sale is reported, based on its
experience.

JM also sells extended roofing product guarantees for periods of 10 to 20 years.
These extended guarantees cover the water tightness of roofing systems resulting
from defects in materials or deficiencies in workmanship. Revenue on these
product guarantees is recognized over the contract period in proportion to costs
incurred.

(I)  Workers' Compensation

JM accrues a liability for workers' compensation claims at present value, due to
the fixed and determinable nature of the claim payments, based upon an
evaluation of historical claims data and expected future claims. In addition, JM
records a receivable at present value for the portion of outstanding claims
covered by third-party insurers.

(J)  Advertising Costs

Advertising costs are expensed as incurred and totaled $11.7 million, $11.3
million and $9.8 million in 1999, 1998 and 1997, respectively.

(K)  Income Taxes

General business tax credits are accounted for as reductions of income tax
expense in the year in which the related expenditures become eligible for
investment benefit under applicable tax regulations.

(L)  Reclassifications

Certain prior year information has been reclassified to conform with the current
year presentation.

Note 2:
Financial Instruments

JM has had limited involvement with derivative financial instruments and does
not use them for trading purposes. In order to fix a portion of JM's variable
interest rate debt and reduce the aggregate risk to movements in interest rates,
JM entered into interest rate swap transactions with notional values totaling
approximately $99 million.

In addition to reducing risk, the interest rate swaps have a correlation to the
underlying debt obligation, and therefore, qualify for hedge accounting. At
December 31, 1999 the fair market value of these instruments reflected
unrecognized losses of $0.3 million. (For additional information on fair market
value disclosures, see Note 7.)

JM enters into foreign exchange forward contracts to hedge against currency
fluctuations on certain material foreign currency exposures and records a
receivable/payable which is classified consistently with the related outstanding
foreign currency exposure. JM did not have any significant forward exchange or
commodity contracts outstanding at December 31, 1999 or 1998.

JM had outstanding letters of credit totaling $14.5 million and $16.5 million as
of December 31, 1999 and 1998, respectively. The majority of the outstanding
letters of credit at December 31, 1999 were issued under JM's revolving credit
facilities (see Note 7), with the remainder collateralized by cash. Of the
outstanding letters of credit, $8.5 million relate to JM's guaranty of
indebtedness of a joint venture in China, of which JM has a 60 percent interest.

JM maintains cash and cash equivalents and certain other financial instruments
with various financial institutions throughout the world. JM invests excess cash
in a diversified portfolio of high-quality money market instruments

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

consistent with the preservation of capital and the maintenance of liquidity.
JM's investment policies require diversification of investments and include
restrictions on maturity and credit quality. JM monitors compliance with these
restrictions on an ongoing basis. JM has not experienced any material losses
related to these investments.

JM does not obtain collateral or other security to support financial instruments
subject to credit risk, but monitors the credit standing of counterparties. JM
is exposed to credit losses in the event of nonperformance by the counterparties
to its financial instruments, but does not anticipate any significant
off-balance-sheet credit risk of accounting loss. JM anticipates that
counterparties will be able to fully satisfy their obligations under the
contracts.

At December 31, 1999 JM held investments in debt securities that were classified
as held-to-maturity with an amortized cost basis of $7.2 million, which
approximated fair value. JM's investments in held-to-maturity debt securities at
December 31, 1999 were classified on the balance sheet as marketable securities
of $3.6 million and other assets of $3.6 million, depending upon the nature and
maturity of the investments. Of these securities, $3.6 million had contractual
maturities within one year; the remainder mature in one to five years.
Additionally, at December 31, 1999 JM had investments in available- for-sale
debt securities, principally escrowed funds, that were classified on the balance
sheet as other assets of $4.7 million. The amortized cost basis of these
securities approximated fair value. Of these securities, $4.7 million had
contractual maturities within one year.

At December 31, 1998 JM held investments in debt securities that were classified
as held-to-maturity with an amortized cost basis of $10.9 million, which
approximated fair value. JM's investments in held-to-maturity debt securities at
December 31, 1998 were classified on the balance sheet as marketable securities
of $4.2 million and other assets of $6.7 million, depending upon the nature and
maturity of the investments. Of these securities, $4.2 million had contractual
maturities within one year; the remainder mature in one to five years.
Additionally, at December 31, 1998, JM had investments in available- for-sale
debt securities, principally escrowed funds, that were classified on the balance
sheet as other assets of $5.2 million. The amortized cost basis of these
securities approximated fair value. Of these securities, $5.1 million had
contractual maturities within one year.

During 1999, 1998 and 1997 JM sold securities that had been classified as
available-for-sale, resulting in proceeds of $9.7 million, $30.2 million and
$45.7 million, respectively, which approximated the carrying value each year.

Included in allowances are doubtful accounts of $3.9 million and $5 million at
December 31, 1999 and 1998, respectively. JM generally requires no collateral on
receivables. The provision for doubtful accounts charged (credited) to costs and
expenses related to continuing operations was $0.9 million for 1999, $0.4
million for 1998 and $(0.2) million for 1997.

JM's international subsidiaries had borrowing and working capital facilities
totaling $19.4 million, of which $12.8 million was available at December 31,
1999 (also see Note 7: Long-Term Debt - "Revolving Credit Facilities"). These
facilities are principally secured by certain receivables and cash of JM's
international subsidiaries.

Revolving Credit Facilities

In 1998 JM arranged unsecured multicurrency revolving credit facilities totaling
approximately $750 million at a floating interest rate of LIBOR plus a margin
with a termination date of May 15, 2003. The credit facilities were used in May
1998 to repurchase substantially all of the $400 million of 10.875 percent Johns
Manville International Senior Notes. The deposit of $227.3 million for the
acquisition of Spunbond/Monofilament assets ("Monobond") drawn during December
1998 was also borrowed from the credit facilities. At December 31, 1999 $285.1
million of borrowings under the credit facilities were outstanding at interest
rates ranging from 3.82 percent to 6.5 percent. The remaining credit facilities
are available for funding acquisitions and capital expenditures, and other
corporate purposes.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

$200 Million Senior Notes

In July 1999 JM issued $200 million of unsecured senior notes to certain
institutional investors in a private debt offering in two tranches: $75 million
at 7.71 percent due in 2006; and $125 million at 7.92 percent due in 2009. The
proceeds were used to repurchase shares from the Trust (see Note 9) and repay
bonds payable to the Trust.

Bonds Payable to the Trust

On June 30, 1999 JM prepaid bonds payable to the Trust in the principal amount
of $23.9 million (see Note 18). These bonds consisted of a series of fixed
payments totaling $75 million per year in 2013 and 2014, discounted at 13
percent.

10.875 Percent Senior Notes

In December 1999 JM called the remaining $2.5 million principal amount of its
10.875 percent Johns Manville International Senior Notes due 2004.

Long-term debt maturities at December 31, 1999 are as follows:

JM's agreements with its lenders contain financial and general covenants. These
include, among other things, limitations on borrowings, investments and asset
dispositions, and maintenance of various financial ratios. Noncompliance with
these or other covenants, or the occurrence of any other event of default, could
result in the termination of existing credit agreements and the acceleration of
debt owed by JM and its subsidiaries. At December 31, 1999 JM was in compliance
with these covenants.

At December 31, 1999 JM's long-term debt totaled $506.6 million, which
approximated fair value. At December 31, 1998 JM's long-term debt totaled $587.8
million and had an estimated fair value of $603.3 million. Generally the fair
value of JM's long-term debt is an estimate based on quoted market prices, when
available, or the discounted cash flow method.

Commitments and Contingencies

Total rental expense related to continuing operations was $13.4 million in 1999,
$14 million in 1998 and $12.5 million in 1997.

JM has various commitments for sales and purchases in the ordinary conduct of
business. In the aggregate, such commitments do not differ significantly from
current market prices or anticipated usage requirements.

Contingent Product Liability

Between 1988 and 1992 JM manufactured phenolic roofing insulation
which may, under certain circumstances, contribute to the corrosion of metal
decks on which it is installed. Since 1993 JM has had a program to voluntarily
inspect such metal decks and remediate where appropriate. JM has accrued for
costs relating to future inspections, remediation and anticipated claims. These
accruals are based on JM's historical experience regarding the incidence of
corrosion and the cost of remediation and include a number of assumptions
related to the types

                               Johns Manville/36
<PAGE>

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

and remaining expected lives of roofs on which phenolic insulation has been
installed. Further, these accruals reflect JM's recent experience and
expectations for the future inspection and remediation program.

Pursuant to reimbursement agreements with JM's liability carriers and the former
owner of the phenolic roofing insulation business, JM is entitled to receive
reimbursement for a substantial portion of future costs to be incurred by JM for
inspection and remediation.

In 1996 JM and a third party were named as defendants in two class action cases,
now consolidated, filed in U.S. District Court in Boston, Mass. The plaintiffs
purport to represent all building owners in the U.S. with phenolic insulation
installed on their roof decks and seek damages and injunctive relief, including
an order requiring the removal and replacement of the phenolic insulation and
remediation of any deck corrosion. JM has reached a conditional agreement in
principle with respect to the settlement of these cases.

JM has reviewed its historical inspection and remediation experience, its
expectations for the future inspection and remediation program, the terms and
collectibility of amounts under the reimbursement agreements, and the terms and
probability of concluding the conditional settlement agreement in principle
discussed above. Based on the information available to date and subject to the
assumptions described above, if additional costs are incurred in excess of the
accrued and reimbursable amounts, such costs are not expected to have a material
adverse effect on JM's financial condition, liquidity or results of operations.

Environmental Contingencies

At December 31, 1999 JM had remediation activities in progress at four sites,
out of a total of 15 such sites for which JM has identified environmental
conditions requiring remediation. In addition, JM has been identified as a
potentially responsible party at 13 non-Company owned or operated sites under
the federal Comprehensive Environmental Response, Compensation and Liability Act
("CERCLA") or similar state legislation. Of these 13 sites, JM's potential
liability for 11 sites will be determined pursuant to a global CERCLA order (the
"Order") described in the following paragraph. Two of the sites may not be
subject to the Order and, accordingly, JM could be jointly and severally liable
for costs of remediating these sites. However, both sites have multiple
potentially responsible parties working with the regulatory agencies. In
addition, JM's disposal percentage is at or near the de minimis level at both
sites. During 1999 JM settled its CERCLA and Resource Conservation and Recovery
Act ("RCRA") liability at three sites under the Order, of which one is final.

In 1994 the U.S. government and JM settled certain litigation concerning JM's
disposal activities prior to consummation of its plan of reorganization. The
Order, which was made a court order, limits JM's future liability under both
CERCLA and RCRA to 55 percent of its share of site-wide response costs and
natural resources damages without regard to joint and several liability for
disposals made by JM prior to consummation of JM's plan of reorganization. The
Order resolved JM's liability at certain historical sites and also covers CERCLA
and RCRA liability for other disposal sites at which the U.S. Environmental
Protection Agency ("EPA") has incurred or may incur response costs and which
were used by JM prior to consummation of the plan of reorganization. The Order
provides that the amount JM will be obligated to pay, in the aggregate, for such
sites shall never exceed $850,000 during any given year. The EPA and others from
time to time commence cleanup activities at such sites and in the future the EPA
and others may assert claims against JM with respect to such sites. JM believes
that all such activities and claims, if any, will be subject to the Order.

At December 31, 1999 and 1998 JM's balance sheet included undiscounted accruals
for environmental remediation costs, including ongoing compliance, maintenance
and monitoring costs, of $31.1 million and

                               Johns Manville/37
<PAGE>

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

$34.8 million, respectively. JM paid $3.9 million and $1.7 million for
environmental cleanup in 1999 and 1998, respectively. JM believes that amounts
paid in 1999 are representative of JM's 2000 environmental cleanup costs. JM
further anticipates expenditures relating to costs currently accrued to be made
over approximately the next 15 years.

In addition, JM's December 31, 1999 balance sheet included a liability of $21.9
million related to the demolition and restoration of a previously closed
manufacturing facility. JM spent $0.6 million in 1999 and expects to spend
approximately $7.1 million in 2000, pending federal and state regulatory agency
approval. The demolition and restoration is expected to be completed in 2002,
with the majority of the liabilities settled by that time.

As a result of factors such as changes in federal and state regulations, the
application and effectiveness of remedial actions, the difficulty in assessing
the extent of environmental contamination, and the allocation of costs among
potentially responsible parties, actual costs to be incurred for environmental
cleanup may vary from previous estimates. Subject to the uncertainties inherent
in evaluating environmental exposures, and based on information presently
available, including JM's historical remediation experience, currently enacted
environmental laws and regulations, the Order and existing remediation
technology, JM believes that if additional costs are incurred in excess of the
accrued amounts, such costs are not expected to have a material adverse effect
on JM's financial condition, liquidity or results of operations.

Note 9:
Stockholders' Equity

In July 1999 JM purchased 12.2 million shares of its common stock from the Trust
at $13.675 per share. Accordingly, treasury stock, at cost, of $166.8 million
was recorded. In the second quarter of 1998, JM purchased 3.6 million shares of
its common stock from the Trust at $13 per share and recorded treasury stock, at
cost, of $46.8 million.

Note 10:
Stock Compensation Plans

General

JM's stock compensation plans grant eligible employees deferred stock rights and
options to purchase shares of JM's common stock. JM also has a noncompensatory
employee stock ownership plan for its worldwide employees. This plan includes
options granted in 1997 and also enables employees to purchase stock directly
from the market and through JM savings plans. At December 31, 1999 approximately
2 million and 3.7 million shares were reserved for issuance under stock
compensation and noncompensatory plans, respectively.

                               Johns Manville/38
<PAGE>

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

The amount of compensation expense recognized for all stock-based compensation
plans was $0.8 million, $6.2 million and $2.7 million for the years ended
December 31, 1999, 1998 and 1997, respectively.

Deferred Stock Rights

Deferred stock rights entitle participants to the receipt of shares of common
stock upon vesting and dividend equivalents, but no voting rights prior to
vesting. The deferred stock rights are restricted as to disposition and are
subject to forfeiture prior to vesting upon certain circumstances. At December
31, 1999 there were 234,834 deferred stock rights outstanding, with vesting
through December 31, 2000. Deferred stock rights were granted as follows:

===================================================
</TABLE>

Stock Options

JM applies APB Opinion No. 25, "Accounting for Stock Issued to Employees" ("APB
No. 25") and related interpretations in accounting for its fixed stock options.
Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" ("SFAS No. 123") was issued in 1995, and if fully adopted would
change, among other things, the methods for recognition of expense on JM's plans
involving stock options. JM's stock options were granted at exercise prices
equal to, or in excess of, market prices on the grant dates, and therefore no
compensation cost was recognized in accordance with APB No. 25.

The substantial majority of the options outstanding at December 31, 1999, other
than those granted under the noncompensatory plan, vested by December 31, 1997
with the remainder vesting through December 10, 2001. These options expire
between December 31, 2005 and December 10, 2008.

Under the noncompensatory plan, JM granted approximately 1.6 million options to
employees at $12.19 per share in 1997, of which 1.2 million were outstanding at
December 31, 1999. Half of these options vest on July 1, 2000, with the
remainder vesting in 2002. These options expire on December 31, 2002.

Recognition of compensation expense under SFAS No. 123 is optional. However, had
compensation cost been determined based on the fair value at grant dates for
stock option awards consistent with SFAS No. 123, JM's net income and earnings
per share for the years ended December 31, 1999, 1998 and 1997 would have been

Earnings per Common Share

Basic earnings per common share amounts are based on the weighted average number
of common shares outstanding during the year. The diluted earnings per common
share computation further includes all dilutive potential common shares
outstanding during the year. The basic and diluted earnings per common share
amounts are determined using the reported net income and the following common
equivalent shares:

Stock options to purchase 0.2 million, 1 million and 2.3 million common shares
in 1999, 1998 and 1997, respectively, were not included in the computation of
diluted earnings per common share because the stock options' exercise prices
were greater than the average market price of the common shares.

Pension obligation                            $(29,045)   $(30,277)

Projected benefit obligations were determined using a discount rate of 6.5
percent in 1999 and 7 percent in 1998. The rate of increase in future
compensation levels for salary-related plans was 3 percent in 1999 and 4 percent
in 1998.

Pension expense and projected benefit obligations under each of these
plans are determined using assumptions regarding discount rates, rates of
increase in future compensation levels and expected long-term rates of return on
assets. These assumptions are subject to prevailing economic conditions and,
accordingly, JM believes it is reasonably possible that a change in these
assumptions may occur in the near term.

Voluntary Savings Plans

JM provides voluntary savings plans in which eligible U.S. employees of JM may
participate. Employees may make contributions of up to 16 percent of their
compensation. JM matches up to six percent of certain contributions at rates
ranging from 15 percent to 100 percent, depending on JM's performance. JM's
contributions to the savings plans were $10.2 million in 1999, $8.8 million in
1998, and $7.1 million in 1997.

Other Postretirement Benefits

Medical and life insurance coverage is provided to eligible U.S. and Canadian
retirees of JM and their dependents under defined benefit plans. The

The postretirement benefit expense was calculated using a discount rate of 7
percent in 1999 and 7.5 percent in 1998 and 1997.

JM's unfunded postretirement benefit obligation reconciled with the amounts
shown in JM's consolidated balance sheet as of December 31, is as follows:

The current portions of $21.7 million and $20.7 million of the postretirement
benefit obligation are reflected in compensation and employee benefits as of
December 31, 1999 and 1998, respectively. The accumulated postretirement benefit
obligations were determined as of December 31, 1999 and 1998 using discount
rates of 7.5 percent and 7 percent, respectively. JM utilizes a discount rate
based on available high-quality corporate bonds. For measurement purposes, a 7
percent annual rate of increase in the per capita cost of covered medical
benefits was assumed for 2000; the rate was assumed to decrease gradually to 5.5
percent in 2003 and remain at that level thereafter.

Assumed health care cost trend rates have a significant effect on the amounts
reported for health care plans. Increasing the assumed health care cost trend
rates by one percentage point in each year would increase the accumulated
benefit obligation as of December 31, 1999 by $11.3 million, and the aggregate
of the service and interest cost components of the periodic cost for the year
then ended by $0.9 million. Meanwhile, decreasing the assumed health care cost
trend rates by one percentage point in each year would decrease the accumulated
benefit obligation as of December 31, 1999 by $10 million, and the aggregate of
the service and interest cost components of the periodic cost for the year then
ended by $0.8 million.

JM's assumptions regarding the discount rate and annual rate of increase in the
per capita cost of covered medical benefits are subject to prevailing economic
conditions. Accordingly, JM believes it is reasonably possible that a change in
these assumptions may occur in the near term.

Workers' Compensation

The workers' compensation liability and related receivable at gross and present

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

The present value of the liability is reflected in other accrued liabilities and
other noncurrent liabilities. The liability and receivable were measured using
risk-free discount rates of 6 percent and 5 percent at December 31, 1999 and
1998, respectively, which reflect rates of return on available U.S. Treasury
securities with maturities similar to the timing of expected claim payments.
Although JM is exposed to credit losses in the event of nonperformance by its
insurers, JM anticipates claims for insurance coverage will be fully satisfied.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

The deferred tax asset related to Trust deductions primarily represents common
stock held by the Trust that is not yet deductible for income tax purposes. The
deferred tax asset related to Trust deductions includes $134.9 million generated
from the issuance of stock to the Trust. JM receives a tax deduction for the
amount of any dividends paid on shares of JM's common stock held by the Trust.
In addition, JM receives a tax deduction when the Trust sells some or all of its
shares of JM common stock and distributes the proceeds to its beneficiaries or
transfers the proceeds to a specific settlement fund. If the Trust were to sell
its JM stock at a price greater than JM's carrying value, JM may receive a tax
benefit in excess of the deferred tax asset reflected for financial reporting
purposes. Likewise, if the Trust were to sell the stock at a price lower than
the carrying value, JM would receive a tax benefit less than the deferred tax
asset reflected for financial reporting purposes.

Under Section 468B of the U.S. Internal Revenue Code, JM is responsible for
income taxes on the taxable income of the Trust's specific settlement fund at a
tax rate of 15 percent. Any such taxes paid by JM will generate a tax deduction
for JM. JM cannot predict the amount of any such future tax obligations.
However, related liabilities could become material in certain situations
including the Trust monetizing, and retaining the proceeds of, a significant
portion of its investment in JM's common stock or the settlement of this
obligation between JM and the Trust. During 1999 and 1998 JM incurred
approximately $4.2 million and $3 million of these taxes, respectively, before
any U.S. federal or state benefit.

The Trust transferred approximately $234.6 million and $69.2 million in 1999 and
1998, respectively, to the specific settlement fund within the Trust or to
claimants generating corresponding current tax deductions for JM. The cash taxes
paid by JM in the U.S. were substantially lower than statutory rates due to JM's
deductions related to payments made to the Trust and tax credit carryforwards.

During 1999 JM realized $7.1 million of foreign tax credit carryforwards, which
were not previously recognized as JM considered realization remote. JM estimates
that, as of December 31, 1999, $10.2 million of the gross deferred tax asset may
not be realized. This amount relates to remaining foreign tax credit
carryforwards that may expire unused. Accordingly, a full valuation allowance
has been provided for these amounts. The 1997 valuation allowance reflected an
$18.2 million decrease primarily due to the utilization of general business
credit carryforwards that JM previously believed would expire unused. In
accordance with Statement of Financial Accounting Standards No. 109, "Accounting
for Income Taxes," the valuation allowance on JM's deferred tax asset is subject
to change as forecasts of future years' earnings and the estimated timing of the
utilization of JM's tax benefits and credit carryforwards are revised, including
actions by the Trust with respect to its ownership of JM stock.

The tax effect of the temporary differences giving rise to the noncurrent net
deferred tax liability is as follows:

As of December 31, 1999 JM had $24.1 million of U.S. federal credit for prior
year minimum tax carryforwards and $10.2 million of U.S. foreign tax credit
carryforwards. There is no expiration date on the prior year minimum tax credit;
however, it can only be applied against regular tax. The foreign tax credits
expire December 31, 2003.

Undistributed earnings intended to be reinvested indefinitely by the foreign
subsidiaries totaled $72.6 million at December 31, 1999. The determination of
the deferred tax liability related to these undistributed earnings is not
practicable.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

Note 17:
Discontinued Operations

During 1997 JM adjusted the estimated gain recognized in 1996 on the disposition
of Riverwood International Corporation. The adjustment, resulting in an
additional net gain on disposal of discontinued operations of $19.5 million,
arose from the expiration of certain indemnification obligations to the
purchaser of Riverwood and from the determination of certain income tax
consequences of the disposition, which were finalized with the completion of
JM's 1996 income tax returns.

Note 18:
Early Extinguishment of Debt

On June 30, 1999 JM prepaid bonds payable to the Trust in the principal amount
of $23.9 million, resulting in a loss on the early extinguishment of debt of
$5.8 million, net of taxes of $3.6 million.

In 1998 JM repurchased, through a cash tender offer, substantially all of the
$400 million of 10.875 percent Johns Manville International Senior Notes due
2004. This transaction resulted in an extraordinary loss on the early
extinguishment of debt of $31.8 million, net of taxes of $18.1 million.

Note 19:
Cumulative Effect of Accounting Change

Effective January 1, 1998 JM changed its method of accounting for glass furnace
rebuild costs to the capitalization method from the allowance method. Under the
capitalization method, costs to periodically rebuild the refractory components
of the glass furnaces are capitalized when incurred and depreciated on a
straight-line basis over the estimated useful life of the rebuild. The
capitalization method provides an improved measure of JM's capital investment
and is consistent with industry practice. Previously, estimated costs to rebuild
furnaces were credited to an allowance and charged to operations over the
estimated period to the next rebuild date. The cumulative effect of this change
in accounting principle increased 1998 earnings by $27.4 million, net of taxes
of $17.9 million. This change resulted in an increase in depreciation expense
but eliminated the provision for furnace rebuilds. The pro forma effect of this
change on net income was not material.

Note 20:
Comprehensive Income

Comprehensive income generally includes changes in separately reported
components of equity along with net income. Components of equity included in
comprehensive income were as follows:

Supplemental Cash Flow Information

In connection with the consolidated statement of cash flows, cash paid for
interest related to continuing operations during 1999, 1998 and 1997 was $23.7
million, $33.9 million and $48.1 million, respectively. Cash paid for income
taxes during 1999, 1998 and 1997 was $34.8 million, $23.5 million and $48.7

Note 22:
Acquisitions

Engineered Products Segment

On January 1, 1999 JM completed the acquisition of Monobond. This acquisition
expands existing product lines of JM's Engineered Products segment in North
America, Europe and China. The cash payment for this acquisition, accounted for
under the purchase method, was $227.3 million. The acquisition was financed with
borrowings from JM's credit facilities drawn during 1998, shown as the
acquisition deposit on JM's December 31, 1998 balance sheet. During 1999 the
allocated purchase price was adjusted to reflect the completion of asset
valuations, and the determination of preacquisition and purchase price
contingencies. The allocation includes the transfer of ownership of a plant
located in China, and adjustment of the value of working capital received, which
will be finalized in early 2000, pursuant to the purchase contract. JM's
December 31, 1999 balance sheet reflects the following purchase price
allocation:

Roofing Systems Segment

On September 2, 1999 JM acquired certain polyisocyanurate roofing insulation and
sheathing foam business operations. In connection with this acquisition, JM
assumed, and subsequently repaid, $12.5 million of debt. This acquisition
complements existing JM product lines and is accounted for under the purchase
method.

Note 23:
New Accounting Pronouncements

In June 1998 the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities." This statement, along with Statement of Financial
Accounting Standards No. 137, "Accounting for Derivative Instruments and Hedging
Activities - Deferral of the Effective Date of FASB Statement No. 133 - an
amendment of FASB Statement No. 133" issued in July 1999, is effective for all
fiscal quarters of fiscal years beginning after June 15, 2000 and establishes
accounting and reporting standards for derivative instruments and for hedging
activities. It requires that JM recognize all derivatives as either assets or
liabilities in the statement of financial position and measure those instruments
at fair value. At this time, JM cannot determine the effects, if any, adopting
this statement will have on its financial condition presentation or results of
operations.

Note 24:
Business Segments and Geographic Area Information

JM reports separately its operating results in the following three principal
business segments: Insulation, Roofing Systems and Engineered Products. JM's
reportable business segments are strategic business units organized by product.
Consistent with JM's internal reporting, business segments include allocated
corporate expenses. The 1998 mining royalty sale proceeds are reported in
corporate and eliminations.

The Insulation segment consists of JM's building insulation business, which
manufactures fiber glass wool insulation for walls, attics and floors in
residential and commercial buildings; commercial and industrial insulation
business, which manufactures pipe and duct insulation for use in commercial
buildings, factories, refineries and other industrial applications; and original
equipment manufacturers ("OEM") insulation business, which manufactures thermal
and acoustic insulation for aircraft, marine vessels, automobiles and heating,
ventilating and air conditioning ("HVAC") and other equipment.

The Roofing Systems segment consists of JM's commercial and industrial roofing
systems business, which supplies built-up, modified bitumen and single-ply
membranes; perlite, fiber glass and polyisocyanurate foam insulations; roof
guarantees; and accessories.

The Engineered Products segment consists of mats and fibers, which includes base
fiber, fiber to reinforce gypsum wallboard and plastics, fiber glass and
polyester spunbond mats for roofing and flooring applications and monofilament
used in the paper industry; glass fabrics for wall coverings; and fiber glass
and synthetic media for high efficiency air filtration systems, face masks,
respirators, vacuum bags, sorbents and liquid filtration applications.
Filtration also produces fine fibers for specialty manufacturers who supply
filtration media for use in clean rooms and various battery separator
applications.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

Notes to Business Segments and Geographic Area Information:

(A) Net sales included in eliminations relate principally to the elimination of
intersegment and intergeographic sales (at prices approximating market).
Intersegment sales principally relate to sales from the Engineered Products
segment to the Roofing Systems segment. Intergeographic sales principally relate
to insulation shipments from the U.S.

(B) Operating assets primarily include amounts directly assigned to each
segment. These include trade receivables; inventory (at standard cost);
goodwill; property, plant and equipment; and capitalized software. Capitalized
software included in operating assets was $12 million, $10 million and $12
million in 1999, 1998 and 1997, respectively. Corporate operating assets relate
principally to the adjustment of business segment inventories to a LIFO basis.

Assets not directly assigned to business segments principally include cash and
equivalents, marketable securities, deferred tax assets, acquisition deposit and
other assets.

(C) Other income (expense), net, in corporate and eliminations for 1998 includes
the mining royalty sale proceeds.

(D) Includes property, plant and equipment purchases and additions to property,
plant and equipment from acquisitions. Additions to property, plant and
equipment from acquisitions were $146.5 million, $24 million and $34.8 million
in 1999, 1998 and 1997, respectively.

MANAGEMENT'S REPORT
- --------------------------------------------------------------------------------

The accompanying consolidated financial statements have been prepared by
management in conformity with generally accepted accounting principles
appropriate under the circumstances. The representations in the financial
statements and the fairness and integrity of such statements are the
responsibility of management. All of the other financial information in the
Annual Report and Form 10-K is consistent with that in the financial statements.

JM maintains internal accounting control systems to provide reliable financial
information for the preparation of financial statements, to safeguard assets
against loss or unauthorized use and to ensure proper authorization and
accounting for all transactions. Management is responsible for maintenance of
these systems, which is accomplished through communication of established
written codes of conduct, systems, policies and procedures; employee training;
and appropriate delegation of authority and segregation of responsibilities. To
further ensure compliance with established standards and procedures, JM
maintains a substantial program of internal audits. Oversight of management's
financial reporting and internal accounting control responsibilities is
exercised by the Board of Directors, through an Audit Committee that consists
solely of outside directors.

REPORT OF INDEPENDENT ACCOUNTANTS
- --------------------------------------------------------------------------------


To the Stockholders and Directors of Johns Manville Corporation:

In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of income and comprehensive income and stockholders'
equity and of cash flows present fairly, in all material respects, the financial
position of Johns Manville Corporation and its subsidiaries at December 31, 1999
and 1998, and the results of their operations and their cash flows for each of
the three years in the period ended December 31, 1999, in conformity with
accounting principles generally accepted in the United States. These financial
statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
auditing standards generally accepted in the United States, which require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for the opinion expressed above.

</TABLE>

(A) JM's first quarter 1999 income tax expense at an effective rate of 35
percent did not reflect the July 1999 Trust stock sale proceeds benefit as such
proceeds were not anticipated at that time. For the second, third and fourth
quarters, the effective tax rates were approximately 13 percent, 19 percent and
15 percent, respectively, reflecting the stock sale proceeds.

(B) On June 30, 1999 JM prepaid bonds payable to the Trust in the principal
amount of $23.9 million, resulting in a loss on the early extinguishment of debt
of $5.8 million, net of taxes of $3.6 million.

(C) In the second quarter of 1998 JM repurchased, through a cash tender offer,
substantially all of its $400 million of 10.875 percent Johns Manville
International Senior Notes due 2004. This transaction resulted in an
extraordinary loss on the early extinguishment of debt of $31.8 million, net of
taxes of $18.1 million.

(D) Effective January 1, 1998 JM changed its method of accounting for glass
furnace rebuild costs to the capitalization method from the allowance method.
The cumulative effect of this change in accounting principle increased 1998 net
income by $27.4 million, net of taxes of $17.9 million.
