                         NOTES TO FINANCIAL STATEMENTS
 
                                  (UNAUDITED)
 
     (1) In the opinion of Tenneco Inc. (the "Company"), the accompanying
unaudited consolidated financial statements of Tenneco Inc. and its consolidated
subsidiaries ("Tenneco") contain all adjustments (consisting of normal recurring
adjustments) necessary to present fairly the financial position, results of
operations, changes in shareowners' equity, and cash flows for the periods
indicated. The unaudited interim consolidated financial statements have been
prepared pursuant to the rules and regulations of the Securities and Exchange
Commission. Accordingly, they do not include all of the information and
footnotes required by generally accepted accounting principles. The consolidated
financial statements of Tenneco include all majority-owned subsidiaries of the
Company. Investments in 20% to 50% owned companies where the Company has the
ability to exert significant influence over operating and financial policies are
carried at cost plus equity in undistributed earnings and cumulative translation
adjustments since date of acquisition.
 
     Prior year's financial statements have been reclassified where appropriate
to conform to 1998 presentations.
 
     (2) Tenneco is a party to various legal proceedings arising from its
operations. Tenneco believes that the outcome of these proceedings, individually
and in the aggregate, will not have a material adverse effect on its financial
position or results of operations.
 
     (3) Tenneco is subject to a variety of environmental and pollution control
laws and regulations in all jurisdictions in which it operates. Tenneco has
provided reserves for compliance with these laws and regulations where it is
probable that a liability exists and where Tenneco can make a reasonable
estimate of the liability. The estimated liabilities recorded are subject to
change as more information becomes available regarding the magnitude of possible
cleanup costs and the timing, varying costs, and effectiveness of alternative
cleanup technologies. However, Tenneco believes that any additional costs which
may arise as more information becomes available will not have a material adverse
effect on its financial position or results of operations.
 
     (4) In March 1998, the American Institute of Certified Public Accountants
("AICPA") issued Statement of Position ("SOP") 98-1, "Accounting for the Costs
of Computer Software Developed or Obtained for Internal Use," which establishes
new accounting and reporting standards for the costs of computer software
developed or obtained for internal use. This statement will be applied
prospectively and is effective for financial statements beginning after December
15, 1998. The impact of this new standard is not expected to have a significant
effect on Tenneco's financial position or results of operations.
 
     In April 1998, the AICPA issued SOP 98-5, "Reporting on the Costs of
Start-Up Activities," which requires costs of start-up activities to be expensed
as incurred. This statement is effective for financial statements beginning
after December 15, 1998. The statement requires capitalized costs related to
start-up activities to be expensed as a cumulative effect of a change in
accounting principle when the statement is adopted. Tenneco capitalizes certain
costs related to start-up activities and is currently evaluating the new
standard but has not yet determined the impact it will have on its financial
position or results of operations.

     (6) Tenneco adopted Financial Accounting Standards ("FAS") No. 130,
"Reporting Comprehensive Income," in the first quarter of 1998. FAS No. 130
establishes new accounting standards for reporting and display of comprehensive
income and its components. Comprehensive income is the total of net income and
all other nonowner changes in equity in a given period. For the three months
ended March 31, 1998 and 1997, Tenneco's comprehensive income was $52 million
and $18 million, respectively.
 
  The above notes are an integral part of the foregoing financial statements.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS
 
RESULTS OF OPERATIONS
 
     Tenneco reported net income of $75 million, or 44 cents per share on a
diluted basis, for the quarter ended March 31, 1998. (All references to earnings
per share in this Management's Discussion and Analysis are on a diluted basis
unless otherwise noted.) Net income for the first quarter of 1997 was $76
million or 44 cents per share. However, the results for the first quarter of
1997 included a one-time after-tax gain of $23 million, or $.13 per share, which
resulted from the refinancing of two containerboard mill leases. Before this
gain, net income for the quarter ended March 31, 1997 was $53 million, or $.31
per share. The increase from 1997 to 1998 excluding the first quarter 1997
one-time gain resulted from strong performance at both Tenneco Automotive and
Tenneco Packaging. The performance at the operating units was partially offset
by a higher 1998 effective tax rate and greater interest expense.

     Tenneco Automotive's higher first quarter 1998 revenues resulted from
strong sales performance and companies acquired in 1997. Volume gains added $40
million to revenue in the first quarter of 1998. These volume gains resulted
from higher original equipment sales, particularly in North America and Europe.
A total of 18 new vehicle launches to which Tenneco Automotive supplied parts in
the first quarter of 1998 contributed to this volume increase. Worldwide,
Tenneco Automotive supplies exhaust and/or ride control products on most of the
top selling vehicles and is particularly strong in the fast growing North
American light truck and sport utility vehicle segment. The higher original
equipment sales volumes were partially offset by a soft aftermarket in both
North America and Europe. Mild winter weather and declining automotive parts
replacement rates contributed to the aftermarket decline. Tenneco Automotive
began the North American launch of two new aftermarket product lines in the
quarter, helping to lessen the impact of the soft aftermarket. The products
launched were Sensa-Trac(R) with Safe-Tech(TM) shocks and struts and the
Quiet-Flow(TM) muffler.
 
     Companies acquired in 1997, including an exhaust supplier in Mexico and a
ride control joint venture in South Africa, contributed $14 million to revenue
growth.
 
     Partially offsetting Tenneco Automotive's first quarter 1998 revenue
increase was the continued impact of the strong US dollar on revenues earned in
overseas markets. The impact of the strong dollar was $31 million.
 
     Tenneco Packaging's revenue increase occurred in both its specialty and
paperboard businesses. Specialty packaging's revenues increased to $630 million
in the first quarter of 1998 from $504 million in the same period of 1997. The
flexible and protective packaging businesses acquired in April 1997 from NV
Koninklijke KNP BT (KNP) contributed $121 million to this revenue increase. The
remaining increase resulted primarily from favorable pricing in the first
quarter of 1998, particularly in consumer waste bags, aluminum and stretch film.
 
     The paperboard packaging business earned revenues of $379 million in the
first quarter of 1998, up $31 million from the first quarter of 1997. Improved
pricing accounted for this revenue gain. Linerboard pricing continued its
recovery from the depressed prices of early 1997.

     The largest contributor to Tenneco Automotive's operating income increase
was the cost reduction initiatives begun during 1997. Net of inflation and other
cost changes, the cost reduction initiatives contributed $11 million to first
quarter 1998 results. Acquisitions added another $2 million to first quarter
results. While the increase in original equipment volumes had a positive impact
on revenues, the volume declines in the aftermarket, where Tenneco earns higher
margins, largely offset that positive impact at the operating income line. The
strong U.S. dollar partially offset Tenneco Automotive's operating income
increase, reducing operating income earned in foreign markets by $4 million for
the first quarter of 1998.
 
     Tenneco Packaging's operating income increase occurred in both the
specialty and paperboard packaging businesses. Specialty packaging's operating
income increased to $74 million in the first quarter of 1998, up from $49
million in the prior year's quarter. Operating income earned from the flexible
and protective packaging businesses acquired from KNP added $12 million to
operating income in the quarter. Cost reduction initiatives and lower resin
prices contributed $7 million of the operating income increase. The remainder of
the operating income increase resulted from the improved pricing discussed under
"Revenues" above combined with a more favorable product mix as unit volume sales
of higher margin products increased during the quarter.
 
     Paperboard packaging recorded the one-time mill lease refinancing gain in
the first quarter of 1997, the operating income impact of which was $38 million.
Before this gain, paperboard packaging's operating income increased $41 million
to $34 million in the first quarter of 1998. Improved pricing for linerboard and
higher volumes in the 1998 quarter contributed $35 million to the improvement
while lower costs accounted for the remainder of the operating income increase.
 
OTHER
 
     Tenneco's Other expenses increased to $11 million in the first quarter
primarily as a result of costs incurred in the effort to consolidate Tenneco's
North American data center operations and integrate the data center operations
of recently acquired businesses. The consolidation effort will continue
throughout 1998.
 
INTEREST EXPENSE (NET OF INTEREST CAPITALIZED)
 
     Interest expense increased $11 million for the first quarter of 1998
compared to the first quarter of 1997. This increase is primarily attributable
to debt issued to finance acquisitions as well as Tenneco's share repurchase
activity.
 
INCOME TAXES
 
     Tenneco's effective tax rate for the first quarter of 1998 was 36 percent
compared to 29 percent in the 1997 first quarter. The 1997 first quarter rate
was lower as a result of non-recurring foreign tax benefits recognized in that
quarter.

MINORITY INTEREST
 
     Minority interest primarily represents dividends on the preferred stock of
a subsidiary. The increase of $3 million in the first quarter of 1998 resulted
from the dividends paid on additional subsidiary preferred stock which was
issued in December 1997.

  Operating activities......................................  $(34)   $(23)
  Investing activities......................................  (106)    (65)
  Financing activities......................................   128     143

 
     Cash flow from operating activities declined by $11 million in the first
quarter of 1998 compared to the same period in 1997. Income before non-cash
charges for depreciation and deferred income taxes declined by $7 million in the
first quarter of 1998. The lower use of cash in the components of working
capital, which improved by $39 million in the first quarter of 1998 compared to
the same period in 1997, offset by lower cash flow for other operating
activities of $43 million in the first quarter of 1998, caused the remainder of
the decline in operating cash flow.
 
     The increase in cash used for investing activities was principally related
to a higher level of capital expenditures in the first quarter of 1998. Capital
expenditures were $40 million at Automotive, $60 million at Packaging and $2
million for the consolidated data center for the first quarter of 1998, compared
to $37 million at Automotive and $44 million at Packaging for the same period in
1997. Cash flow for other investing activities declined by $22 million during
the first quarter of 1998. Other investing activities during the first quarter
of 1997 included cash adjustments related to acquired companies which did not
recur in 1998.
 
     Financing activities provided cash of $128 million in 1998. Tenneco
incurred short-term debt financing in the first quarter of 1998 of $177 million
to meet its financing needs for capital expenditures and working capital during
the first quarter. This compares to $237 million in short-term debt incurred in
the first quarter of 1997. Tenneco issued $13 million in common stock, primarily
related to employee benefit plans, and repurchased $11 million of common stock
pursuant to its share repurchase program during the first quarter of 1998. This
compares to $10 million in stock issuances and $51 million in share repurchases
in the first quarter of 1997. For the quarter, common stock dividends were $51
million in 1998 and $52 million in 1997.

                                                           $6,066         $5,863
                                                           ======         ======

 
     The increase in debt for the first quarter represents the use of cash
described above. Equity remained unchanged as net income for the quarter was
offset by dividends, share repurchases, and cumulative translation adjustments
resulting from the strong U.S. dollar. As a result of those changes, Tenneco's
debt to capitalization ratio increased to 51.4 percent at March 31, 1998, from
49.7 percent at December 31, 1997.
 
     Tenneco believes it has adequate capital resources available to it to meet
its future capital needs, including strategic acquisitions and announced share
repurchases.

CHANGES IN ACCOUNTING PRINCIPLES
 
     In March 1998, the American Institute of Certified Public Accountants
("AICPA") issued Statement of Position ("SOP") 98-1, "Accounting for the Costs
of Computer Software Developed or Obtained for Internal Use," which establishes
new accounting and reporting standards for the costs of computer software
developed or obtained for internal use. This statement will be applied
prospectively and is effective for financial statements beginning after December
15, 1998. The impact of this new standard is not expected to have a significant
effect on Tenneco's financial position or results of operations.
 
     In April 1998, the AICPA issued SOP 98-5, "Reporting on the Costs of
Start-Up Activities," which requires costs of start-up activities to be expensed
as incurred. This statement is effective for financial statements beginning
after December 15, 1998. The statement requires capitalized costs related to
start-up activities to be expensed as a cumulative effect of a change in
accounting principle when the statement is adopted. Tenneco capitalizes certain
costs related to start-up activities and is currently evaluating the new
standard but has not yet determined the impact on its financial position or
results of operations.
