Note 2 - Acquisitions

During the first quarter of 1997, the Company acquired the assets of Ergon
Nonwovens, Inc., a manufacturer of synthetic meltblown nonwoven products.
During the second quarter of 1997, the Company acquired the Mitex group of
companies.  Mitex manufactures fiber glass wall covering fabrics used primarily
in commercial and industrial buildings, and has manufacturing facilities in
Sweden and the United Kingdom.   The combined purchase price for these
acquisitions was $93 million, net of cash acquired, financed from existing cash
balances and borrowings of $45 million, net, from international credit
facilities.  These acquisitions, associated with businesses of the Engineered
Products Segment, are accounted for under the purchase method.  The excess of
the combined purchase prices over the estimated fair value of net assets
acquired, or goodwill,





                                      I-5

amounted to approximately $60 million and is being amortized over 20 years
using the straight line method.  This allocation was based on estimates and may
be revised in the future.

Note 3 - New Accounting Pronouncements

During 1997, the Financial Accounting Standards Board issued Statements of
Financial Accounting Standards No. 130, "Reporting Comprehensive Income" ("SFAS
No. 130") and No. 131, "Disclosures about Segments of an Enterprise and Related
Information" ("SFAS No. 131"), both effective for years beginning after
December 31, 1997.  SFAS No. 130 establishes standards for reporting and
display of comprehensive income and its components.  Comprehensive income
generally includes changes in separately reported components of equity along
with net income.  SFAS No. 131 establishes standards for reporting information
about operating segments, along with related disclosures about products,
services, geographic areas and major customers, based on the Company's
disaggregation of an entity for internal operating decisions.

Note 4 - Business Segment Information

Beginning in 1997, the Company reorganized its business segments and will
report separately its operating results in the following three principal
business segments: Insulation, consisting of the residential, commercial and
industrial and original equipment manufacturer ("OEM") insulation businesses;
Roofing Systems, consisting of the commercial and industrial roofing
business; and Engineered Products, consisting of the mats and fibers and
filtration businesses.  The 1996 results were reclassified to conform with the
current presentation format.

ITEM 2.

                    JOHNS MANVILLE INTERNATIONAL GROUP, INC.
                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS


RESULTS OF OPERATIONS
The Company's net sales for the second quarter of 1997 increased $46.6 million,
or 12.2 percent, to $428 million from $381.4 million for the same period of
1996.  Gross profit increased $9.4 million, or 8.7 percent, to $117.9 million
from $108.5 million.  Lower gross profit margins for the second quarter of 1997
compared with the second quarter of 1996 were due principally to lower selling
prices in several businesses.  At the end of 1996, certain management and
financial services provided by Johns Manville Corporation were reorganized and
transferred to the Company.  Therefore, services previously provided by parent
are reflected as selling, general and administrative for 1997. These expenses,
along with research, development and engineering expenses increased slightly
and were lower as a percentage of sales at 11.2 percent for 1997 compared with
12.4 percent for 1996, due primarily to acquisitions.  Income from operations
for the second quarter of 1997 was $66.2 million, up 12.1 percent, compared
with $59.1 million for the second quarter of 1996.

The Company's net sales for the first six months of 1997 increased $99.5
million, or 14.1 percent, to $807 million from $707.5 million for the same
period of 1996.  Gross profit increased $16.5 million, or 8.2 percent, to
$218.6 million from $202.1 million.  Selling, general, administrative and
research, development and engineering expenses increased $4.8 million, or 5.4
percent, to $93.8 million, reflecting expenses of acquired companies.  Income
from operations for the first six months of 1997 increased to $118.2 million
from $116.2 million for 1996.  Exclusive of other income of $7.2 million from
the settlement of certain pension plans in 1996, income from operations for the
first six months of 1997 was up $9.1 million, or 8.4 percent.

Insulation Segment
The Insulation segment's net sales increased $9.9 million, or 5.9 percent, and
$28.5 million, or 8.8 percent, for the second quarter and first six months of
1997 compared with the same periods of 1996.  Income from operations for this
segment increased slightly for both the second quarter and first six months of
1997.  During 1997, the residential, and commercial and industrial businesses
experienced volume gains, benefiting from strong U.S. construction markets.
Competitive pricing pressures related principally to excess industry capacity,
while being offset by improved productivity for commercial and industrial
insulation, led to lower margins and decreases in operating income for
residential insulation business compared with corresponding 1996 periods.

OEM insulation had significantly higher operating income on slightly lower
sales for both 1997 periods, reflecting improved product mix and productivity,
combined with lower overhead costs.

Roofing Systems Segment
Net sales for the Roofing Systems segment increased $36.4 million, or 36.3
percent, and $72.8 million, or 44.7 percent, for the second quarter and first
six months of 1997 compared with the same periods of 1996. Operating income
increased $6.7 million and $11.3 million for the same periods.  These increases
are driven primarily by the incremental 1997 operating results of acquisitions
completed throughout 1996.  Manufacturing efficiencies and absorption of
expenses over higher sales levels raised operating income and also led to
improved margins during 1997.

Engineered Products Segment
The Engineered Products segment's net sales were essentially flat at $122.2
million, and $238.3 million, for the three and six month periods ended June 30,
1997, respectively.  Income from operations decreased slightly to $26.2 million
for the second quarter, and $4.6 million, or 8.3 percent, to $51.1 million for
the first half of 1997.  Net sales for the U.S. mats and fibers business
increased slightly for the first half of 1997 and decreased for the second
quarter, while operating profit decreased for both periods as volume gains and
reduced costs were more than offset by declining selling prices due to
competitive pressures.  Slight improvements for the Company's German operations
on higher sales volumes and improved productivity were partially offset by the
impacts of the strength of the U.S. dollar against the German mark on reported
results.  Net sales for filtration increased for both 1997 periods on higher
volumes due to recent acquisitions in the synthetic filtration media markets.
These improvements were partially offset by competitive pressures, including
lower pricing which led to flat second quarter operating income and
significantly decreased operating income and margins for the first half of
1997.

Compared with the second quarter and first half of 1996, the Company's interest
expense increased $2.2 million and $4.3 million, respectively, for the same
periods of 1997, due primarily to increases in debt balances related to
acquisitions.

LIQUIDITY AND CAPITAL RESOURCES
The Company's agreements with its lenders contain a number of financial and
general covenants.  These include, among other things, restrictions on
borrowings, investments, stock issuances and repurchases, dividends and other
distributions, restrictions on intercompany transactions, including transfers
of cash and transactions with Johns Manville Corporation.  As of June 30, 1997,
the maximum amount available for dividends to be paid to Johns Manville
Corporation under debt covenants of the Company's Senior Notes was
approximately $250 million.  Noncompliance with these or other covenants, or
the occurrence of any other event of default, could result in the termination





                                      I-9
<PAGE>   11
of existing credit agreements and the acceleration of debt owed by the Company
and its subsidiaries.  At June 30, 1997, the Company was in compliance with
these covenants.

At June 30, 1997, the Company had net working capital of $243.5 million,
including cash and marketable securities totaling $97.4 million.  Total cash
and marketable securities located outside the U.S. and Canada were
approximately $38.5 million.   At December 31, 1996, the Company's cash and
marketable securities totaled $140.9 million.   The decrease is due primarily
to acquisitions and seasonal working capital requirements. At June 30, 1997,
the Company had $100 million available under a receivables sale facility for
its domestic short-term working capital requirements.  In addition, the
Company's international subsidiaries had borrowing and working capital
facilities totaling $85 million, of which approximately $31 million was
available at June 30, 1997.  Under these facilities, $45 million, net, was
borrowed to partially finance acquisitions.

The Company's net operating activities provided $20.1 million of cash during
the first six months of 1997.  Net operating activities provided $51.7 million
for the same period of 1996, which included proceeds from the settlement of
pension plans. The Company's cash flows from operating activities are primarily
influenced by sales volume and selling prices.  As discussed in "Results of
Operations," the effects of sales volume increases during the first half of
1997 were partially offset by selling price declines.  Operating activities
also included cash usages for net working capital builds in anticipation of the
construction season which typically peaks during the third quarter.  For the
remainder of 1997, the Company's operating results are expected to benefit from
the integration of acquisitions.  While U.S. housing starts during 1997 are
expected to be comparable to 1996, capacity-related selling price and other
competitive pressures are expected to continue for the residential insulation
business, as well as commercial and industrial insulation, mats and fibers and
filtration businesses for the remainder of the year.

The Company's investing activities for the first half of 1997 consisted of $93
million for acquisitions, net of cash acquired.  The Company's capital
expenditures totaled $47.1 million for the first six months of 1997.  The
Company estimates 1997 capital expenditures of approximately $100 million, of
which approximately $40 million relate to capacity expansion projects
principally to increase mats and fibers production.  As of June 30, 1997,
outstanding purchase commitments for capital projects totaled $19 million.
During the first quarter of 1997, the Company received $23.8 million in
repayment of an advance made to Johns Manville Corporation in 1996 for an
acquisition which was subsequently contributed to the Company.  Investing
activities for 1997 also included proceeds from the Company's June 30, 1997
disposition of its automotive molded parts business, the assets of which were
written down to estimated fair values in 1996.  Investing activities for 1996
included the combined purchase prices for acquisitions of $57 million and
capital expenditures totaling $57.6 million.

In addition to borrowings to partially finance 1997 acquisitions, the Company's
financing activities for 1997 included repayments of debt totaling $30 million
assumed in connection with 1996 acquisitions, which was refinanced with notes
payable to Johns Manville Corporation.

The Company believes that its current cash position, funds available under a
receivables facility and foreign working capital 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, the Company may need to access capital markets to pay the principal of
the $400 million Senior Notes, or in connection with possible significant
future acquisitions.
