                CASE CORPORATION AND CONSOLIDATED SUBSIDIARIES
 
                         NOTES TO FINANCIAL STATEMENTS
 
(1) BASIS OF PRESENTATION
 
  The accompanying financial statements reflect the consolidated results of
Case Corporation ("Case" or the "Company") and also include, on a separate and
supplemental basis, the combination of Case's industrial companies and credit
companies as follows:
 
  Case Industrial--The financial information captioned "Case Industrial"
                reflects the consolidation of all majority-owned subsidiaries
                except for the wholly owned retail credit subsidiaries. The
                credit operations are included on an equity basis.
 
  Case Credit --The financial information captioned "Case Credit" reflects the
                consolidation of Case's retail credit subsidiaries.
 
  All significant intercompany transactions, including activity within and
between Case Industrial and Case Credit, have been eliminated.
 
  In the opinion of management, the accompanying unaudited financial
statements of Case Corporation and Consolidated Subsidiaries contain all
adjustments which are of a normal recurring nature necessary to present fairly
the financial position as of June 30, 1998, and the results of operations,
changes in stockholders' equity and cash flows for the periods indicated. It
is suggested that these interim financial statements be read in conjunction
with the financial statements and notes thereto included in the Company's 1997
Annual Report on Form 10-K. Interim financial results are not necessarily
indicative of operating results for an entire year.
 
  Certain reclassifications have been made to conform the prior years'
financial statements to the 1998 presentation.
 
(2) ACCOUNTING PRONOUNCEMENTS
 
  Effective January 1, 1998, the Company adopted Statement of Financial
Accounting Standards ("SFAS") No. 130, "Reporting Comprehensive Income." This
statement establishes standards for the reporting and display of comprehensive
income and its components. Components of comprehensive income include net
income and all other non-owner changes in equity. SFAS No. 130 requires that
an enterprise classify items of comprehensive income by their nature in a
financial statement for the period in which they are recognized. For interim
reporting, the Company has chosen to disclose comprehensive income in the
Notes to Financial Statements. See Note 9, "Comprehensive Income."
 
  Effective January 1, 1998, the Company adopted SFAS No. 132, "Employers'
Disclosures about Pensions and Other Postretirement Benefits." This statement
standardizes the disclosure requirements for pensions and other postretirement
benefits.
 
  In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities." This statement
establishes accounting and reporting standards for derivative instruments,
including certain derivative instruments embedded in other contracts, and for
hedging activities. This statement must be adopted no later than January 1,
2000, although earlier application is permitted. The Company is currently
evaluating the impact of adopting SFAS No. 133.
 
  Effective January 1, 1998, the Company adopted Statement of Position ("SOP)"
No. 98-1, "Accounting for the Costs of Computer Software Developed or Obtained
for Internal Use." The Company's accounting for costs of computer software
developed or obtained for internal use is consistent with the guidelines
established in the SOP and, as a result, the adoption of this statement had no
effect on the Company's financial position or results of operations.

  Case will adopt SOP No. 98-5, "Reporting on the Costs of Start-Up
Activities," effective January 1, 1999. Adoption of this statement will have no
material effect on the Company's financial position or results of operations.
 
(3) INVENTORIES
 
  Inventories are stated at the lower of cost or market, generally using the
first-in, first-out (FIFO) method. Inventory cost includes material, labor and
overhead.

(4) ASSET-BACKED SECURITIZATIONS
 
  During the first half of 1998, limited-purpose business trusts organized by
Case Credit issued $766 million of asset-backed securities to outside
investors, of which $50 million was issued pursuant to a private placement. As
of June 30, 1998, Case Credit has sold $753 million of U.S. and Canadian retail
notes to the trusts in connection with these issuances. Case Credit will sell
the remaining retail notes to the trusts as receivables are generated. During
the first half of 1997, limited-purpose business trusts organized by Case
Credit issued $830 million of asset-backed securities to outside investors. As
of June 30, 1997, Case Credit had sold $822 million of U.S. and Canadian retail
notes to the trusts in connection with these issuances. The proceeds from the
sale of the retail notes were used to repay outstanding debt and to finance
additional receivables.
 
(5) INCOME TAXES
 
  On a consolidated basis, the Company's first half effective income tax rate
of 31% for 1998 and 32% for 1997 were lower than the U.S. statutory tax rate of
35%, primarily due to recognition of tax benefits associated with the Company's
foreign sales corporation, research and development tax credits and a reduction
in the tax valuation reserve in certain foreign jurisdictions, partially offset
by state income taxes and foreign income taxed at different rates.
 
(6) COMMITMENTS AND CONTINGENCIES
 
 Environmental
 
  Expenditures for ongoing compliance with environmental regulations that
relate to current operations are expensed or capitalized as appropriate.
Expenditures that relate to an existing condition caused by past operations and
which do not contribute to current or future revenue generation are expensed.
Liabilities are recorded when environmental assessments indicate that remedial
efforts are probable and the costs can be reasonably estimated. Estimates of
the liability are based upon currently available facts, existing technology and
presently enacted laws and regulations. All available evidence is considered,
including prior experience in remediation of contaminated sites, other parties'
share of liability at the waste sites and their ability to pay and data
concerning the waste sites

released by the U.S. Environmental Protection Agency or other organizations.
These liabilities are included in the accompanying Balance Sheets at their
undiscounted amounts. Recoveries are evaluated separately from the liability
and, if appropriate, are recorded separately from the associated liability in
the accompanying Balance Sheets.
 
  Case has received and from time to time receives inquiries and/or notices of
potential liability at multiple sites that are the subject of remedial
activities under Federal or state environmental laws and Case may be required
to share in the cost of clean-up. Case is also involved in remediating a
number of other sites, including certain of its currently and formerly
operated facilities or those assumed through corporate acquisitions. Based
upon information currently available, management is of the opinion that any
such potential liability or remediation costs will not have a material adverse
effect on Case's financial position or results of operations.
 
 Product liability
 
  Product liability claims against Case arise from time to time in the
ordinary course of business. There is an inherent uncertainty as to the
eventual resolution of unsettled claims. However, in the opinion of
management, any losses with respect to existing claims will not have a
material adverse effect on Case's financial position or results of operations.
 
 Other
 
  Case is the subject of various other legal claims arising from its
operations, including product warranty, dealer disputes, workmen's
compensation and employment matters. Management is of the opinion that the
resolution of these claims, individually and in the aggregate, will not have a
material adverse effect on Case's financial position or results of operations.
 
(7) ACQUISITIONS
 
  During the second quarter of 1998, the Company acquired certain assets of
the Tyler Industries division ("Tyler") of IBOCO, Inc., a privately owned
company. The acquisition of Tyler, a designer, manufacturer and distributor of
a complete line of chemical and fertilizer sprayers and applicators,
strengthens Case's equipment line for large-scale production agriculture and
provides another application for Case's Advanced Farming Systems. Tyler, with
operations in Benson, Minnesota, had sales of approximately $66 million in
1997.

(10) OTHER MATTERS
 
  The Company's contract with the United Automobile, Aerospace and
Agricultural Implement Workers of America (the "UAW") expired on March 29,
1998. During the second quarter, UAW-represented workers ratified a new 73
month labor agreement with the Company.
 
  The UAW represents approximately 3,300 Case employees at facilities in
Burlington, Iowa; East Moline, Illinois; Burr Ridge, Illinois; Racine,
Wisconsin; and St. Paul, Minnesota.
 
(11) SUBSEQUENT EVENTS
 
  During the second quarter of 1998, Case Credit Corporation increased its
$550 million medium-term note program to $1 billion pursuant to a shelf
registration statement filed with the Securities and Exchange Commission in
May 1998. During the third quarter, and as of the date of this filing, Case
Credit has issued $350 million of its fixed and floating rate medium-term
notes under this program, with maturities of two to three years and interest
rates ranging from 5.9% to 6.1%.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS
 
ANALYSIS OF RESULTS OF OPERATIONS
 
 Three Months Ended June 30, 1998 vs. Three Months Ended June 30, 1997
 
EARNINGS
 
  The Company recorded net income of $126 million for the second quarter of
1998, down 9% or $12 million from $138 million for the second quarter of 1997.
Diluted earnings per share for the second quarter of 1998 was $1.61 per share
as compared to $1.75 per share in the same quarter of 1997, primarily
reflecting the year-over-year decrease in net income partially offset by a
decrease in the number of common shares outstanding.
 
  The Company's industrial operations recorded income, before equity income of
Case Credit, of $108 million in the second quarter of 1998 versus $121 million
in the comparable quarter of 1997. On a pretax basis, the Company's industrial
operations recorded earnings of $155 million in comparison to $177 million in
the same quarter of 1997. The industrial effective income tax rate decreased
from 32% in the second quarter of 1997 to 30% in the second quarter of 1998,
primarily due to tax benefits associated with the Company's foreign sales
corporation, research and development tax credits and reductions in the tax
valuation reserves in certain foreign jurisdictions, partially offset by state
income taxes and foreign income taxed at different rates.
 
  Case's operating earnings for the second quarter of 1998 were $199 million
versus $211 million for the same period in 1997. Case defines operating
earnings as industrial earnings before interest, taxes, changes in accounting
principles and extraordinary items, including the income of Case Credit on an
equity basis. The year-over-year decrease in operating earnings is primarily
attributable to expenses and operating inefficiencies related to the Company's
negotiations with the United Automobile, Aerospace and Agricultural Implement
Workers of America (the "UAW"), unfavorable foreign exchange rates, including
a 17% decline in the value of the Australian dollar, and substantially higher
new product launch expenses, partially offset by pricing and cost reduction
initiatives. The Company's contract with the UAW expired on March 29, 1998.
During the second quarter, UAW-represented workers ratified a new 73 month
labor agreement with the Company.
 
  A reconciliation of the Company's industrial net income to operating
earnings is as follows (in millions):

</TABLE>
 
REVENUES
 
  On a consolidated basis, worldwide revenues increased $133 million or 8% in
the second quarter of 1998 to $1,734 million. Net sales of equipment and parts
increased $125 million or 8% to $1,672 million. The increase in net sales
consists primarily of an 8% volume increase and a 2% improvement in price
realization, partially offset by a 2% deterioration resulting from the impact
of foreign exchange. Net sales in the second quarter of 1998 increased in
North America and Europe, with year-over-year increases of 12% and 7%,
respectively. In addition, net sales in the Company's Latin American region
increased 35% as compared to the prior year. Net sales in the Asia Pacific
region were down 30% versus the prior year due to continued unfavorable
economic conditions in that region. Worldwide, net sales of agricultural
equipment increased 2% over the comparable period in 1997, while second
quarter net sales of construction equipment increased 22% over the same period
in 1997.
 
                                      12
<PAGE>
 
NET SALES
 
  Worldwide net sales of agricultural equipment increased 2% in the second
quarter of 1998 as compared to the second quarter of 1997. The increase in
sales of agricultural equipment in North America was driven by increases in
sales of tractors, hay and forage equipment and implements, partially offset
by decreased sales of combines and cotton pickers. In Europe, the Company
experienced higher year-over-year second quarter sales of combines, cotton
pickers, hay and forage equipment and implements, partially offset by
decreased tractor sales. Year-over-year sales in the Company's Asia Pacific
region decreased, reflecting continued unfavorable economic conditions in that
region. The decrease in agricultural sales in the Asia Pacific region reflects
lower sales of sugar cane harvesters, MAGNUM(TM) and four-wheel drive tractors
and combines, partially offset by increased sales of cotton pickers. In the
Company's Latin American region, the Company experienced increases in year-
over-year sales of tractors, combines and cotton pickers, partially offset by
decreased sales of sugar cane harvesters.
 
  Worldwide net sales of construction equipment increased 22% in the second
quarter of 1998 as compared to the second quarter of 1997. In North America,
second quarter sales of construction equipment increased in all product
categories, led by increased sales of loader/backhoes, skid steers, excavators
and wheel loaders. Net sales of construction equipment in Europe increased in
virtually all product categories, led by significant increases in sales of
excavators, loader/backhoes and skid steers. In the Company's Asia Pacific
region, sales of construction equipment were primarily impacted by lower sales
of loader/backhoes, partially offset by higher excavator and wheel loader
sales, as unfavorable economic conditions in the region continued during the
second quarter of 1998. In the Company's Latin American region, increased
sales of construction equipment reflects increased sales of loader/backhoes,
wheel loaders and excavators, partially offset by lower sales of skid steers.
 
COSTS AND EXPENSES
 
  Cost of goods sold for the industrial operations increased $121 million to
$1,274 million in the second quarter of 1998 as compared to the same period in
1997, primarily due to the sales volume increase. Cost of goods sold as a
percentage of net sales increased to 76.2% in the second quarter of 1998 from
74.5% in the second quarter of 1997. This increase as a percentage of net
sales reflects changes in geographic and product line sales mix, the impact of
foreign currency exchange and operating inefficiencies associated with the
Company's negotiations with the UAW, partially offset by pricing actions and
cost improvement initiatives.
 
  Selling, general and administrative expenses for the industrial operations
increased $18 million to $169 million in the second quarter of 1998 as
compared to $151 million in the second quarter of 1997. As a percentage of net
sales, selling, general and administrative expenses for the second quarter of
1998 was 10.1% as compared to 9.8% in the second quarter of 1997. This year-
over-year increase as a percentage of net sales reflects increases in general
and administrative expenses related to information services and one-time costs
associated with the Company's negotiations with the UAW, as well as increased
selling expenses related to low rate and other sales financing programs,
partially offset by ongoing cost reduction initiatives. Case Industrial makes
payments to Case Credit in an amount equal to the difference between the rate
actually paid by retail customers and the rate charged by Case Credit. These
payments are included in selling, general and administrative expenses of Case
Industrial and are eliminated to arrive at consolidated selling, general and
administrative expenses.
 
  Research, development and engineering expenses increased to $57 million in
the second quarter of 1998 as compared to $46 million in the second quarter of
1997, primarily due to expenditures for new product development.
 
  Interest expense for Case's industrial operations was $26 million for the
second quarter of 1998, $9 million higher than the same period of 1997. The
increase in interest expense was due to higher average debt levels during the
second quarter of 1998 as compared to the second quarter of 1997.

<PAGE>
 
CREDIT OPERATIONS
 
  Net income for the second quarter of 1998 was $18 million as compared to $17
million for the second quarter of 1997. The $1 million increase in year-over-
year net income is primarily due to higher earnings as a result of increased
levels of on-balance-sheet receivables, including higher lease income from
operating leases. These amounts were largely offset by increased interest
expense due to higher average on-book receivables, as well as increased
depreciation of equipment on operating leases.
 
  Case Credit reported total revenues of $80 million for the second quarter of
1998 and $60 million for the second quarter of 1997. Finance income earned on
retail notes and finance leases increased to $32 million in the second quarter
of 1998 as compared to $24 million for the same period in 1997, primarily due
to increased levels of on-balance-sheet receivables. In addition, operating
lease income increased $7 million to a total of $15 million for the second
quarter of 1998, reflecting the growth in Case Credit's operating lease
portfolio.
 
  Interest expense for the second quarter of 1998 was $31 million, up $9
million from the $22 million reported for the second quarter of 1997. The
increase in interest expense resulted from higher average debt levels during
the second quarter of 1998 as compared to the second quarter of 1997,
primarily due to the growth in Case Credit's on-balance-sheet receivables and
increased equipment on operating leases.
 
  Operating expenses increased $9 million to a total of $22 million in the
second quarter of 1998 as compared to the second quarter of 1997. This
increase primarily resulted from higher year-over-year depreciation expense
for equipment on operating leases relating to Case Credit's larger operating
lease portfolio, as well as higher operating expenses in support of Case
Credit's growth initiatives.
 
  As of June 30, 1998, Case Credit's serviced portfolio of receivables
increased 23% over the same time last year to a record $5.8 billion. This
growth resulted from Case Credit's focus on new markets and new products,
including retail financing through Case Credit's European joint venture, Case
Credit Europe S.A.S. Gross receivables originated in the first six months of
1998 increased $557 million or 36% to $2.1 billion versus the same period in
1997. During the second quarter of 1998, Case Credit sold $264 million of U.S.
and Canadian retail notes to limited-purpose business trusts organized by Case
Credit in connection with asset-backed securitization transactions, as
compared to $320 million in the second quarter of 1997. The proceeds from the
sale of the retail notes were used to repay outstanding debt and to finance
additional receivables.
 
 Six Months Ended June 30, 1998 vs. Six Months Ended June 30, 1997
 
EARNINGS
 
  The Company recorded net income of $195 million for the first six months of
1998, down 3% or $7 million from net income of $202 million for the first six
months of 1997. Diluted earnings per share for the first six months of 1998
was $2.48 per share as compared to $2.57 per share in the same period of 1997,
primarily reflecting the year-over-year decrease in net income.
 
  The Company's industrial operations recorded income, before equity income in
Case Credit, of $158 million in the first six months of 1998 versus $163
million in the first six months of 1997. On a pretax basis, the Company's
industrial operations recorded earnings of $227 million in comparison to $240
million in 1997, a $13 million or 5% decrease from the first six months of
1997. The industrial effective income tax rate decreased from 32% in the first
half of 1997 to 30% in the first half of 1998 primarily due to tax benefits
associated with the Company's foreign sales corporation, research and
development tax credits and a reduction in the tax valuation reserves in
certain foreign jurisdictions, partially offset by state income taxes and
foreign income taxed at different rates.
 
  Case's operating earnings for the first six months of 1998 were $308 million
versus $314 million for the same period in 1997. Case defines operating
earnings as industrial earnings before interest, taxes, changes in
 
                                      14

accounting principles and extraordinary items, including the income of Case
Credit on an equity basis. The year-over-year decrease in operating earnings
is primarily attributable to expenses and operating inefficiencies related to
the Company's negotiations with the UAW, unfavorable foreign exchange rates
and substantially higher new product launch expenses, partially offset by
pricing and cost reduction initiatives.
 
  A reconciliation of the Company's industrial net income to operating
earnings is as follows (in millions):

REVENUES
 
  On a consolidated basis, worldwide revenues increased $282 million or 10% in
the first six months of 1998 to $3,115 million. Net sales of equipment and
parts increased $261 million or 10% to $2,984 million. The increase in net
sales consists primarily of a 10% volume increase and a 2% improvement in
price realization, partially offset by a 2% deterioration resulting from the
impact of foreign exchange. Net sales in the first six months of 1998
increased in North America and Europe, with year-over-year increases of 14%
and 5%, respectively. Net sales also increased in the Company's Latin American
region, increasing 43% as compared to the prior year. Net sales in the Asia
Pacific region were down 26% versus the prior year as unfavorable economic
conditions continued in this region during the first six months of 1998.
Worldwide, net sales of agricultural equipment increased 8% over the
comparable period in 1997, while net sales of construction equipment increased
18% over prior year levels.
 
NET SALES
 
  Worldwide net sales of agricultural equipment increased 8% in the first six
months of 1998 as compared to the first six months of 1997. The increase in
sales of agricultural equipment in North America was driven by increases in
sales of tractors, combines, implements and hay and forage equipment,
partially offset by decreased sales of cotton pickers. In Europe, the Company
experienced higher year-over-year first half sales of combines, cotton
pickers, implements and hay and forage equipment, partially offset by
decreased sales of tractors. In the Company's Asia Pacific region,
agricultural sales were down in all product categories, reflecting continued
unfavorable economic conditions in that region. In the Company's Latin
American region, the Company experienced increases in year-over-year sales of
tractors, combines and cotton pickers, partially offset by decreased sales of
sugar cane harvesters.
 
  Worldwide net sales of construction equipment increased 18% in the first six
months of 1998 as compared to the first six months of 1997. In North America,
first half sales of construction equipment increased in all product
categories, driven by significant increases in sales of excavators, skid
steers and wheel loaders. The increase in net sales of construction equipment
in Europe primarily reflects increased sales of excavators, loader/backhoes,
wheel loaders and skid steers. Unfavorable economic conditions continued
during the first six months of 1998 in the Company's Asia Pacific region. As a
result, the Company experienced lower year-over-year sales of construction
equipment in most product categories, partially offset by increased sales of
excavators. In the Company's Latin American region, increased sales of
construction equipment reflects increased sales of wheel loaders and
loader/backhoes.

COSTS AND EXPENSES
 
  Cost of goods sold for the industrial operations increased $230 million to
$2,293 million in the first six months of 1998 as compared to the same period
in 1997, primarily due to the sales volume increase. Cost of goods sold as a
percentage of net sales increased to 76.8% in the first six months of 1998
from 75.8% in 1997. This increase as a percentage of net sales reflects
changes in geographic and product line sales mix, the impact of foreign
currency exchange and operating inefficiencies associated with the Company's
negotiations with the UAW, partially offset by pricing actions and cost
improvement initiatives.
 
  Selling, general and administrative expenses for the industrial operations
increased $25 million to $321 million in the first six months of 1998, as
compared to $296 million in the comparable period of 1997. This year-over-year
increase reflects increases in general and administrative expenses related to
information services and one-time costs associated with the Company's
negotiations with the UAW, as well as increased selling expenses related to
low rate and other sales financing programs, partially offset by the impact of
foreign currency and ongoing cost reduction initiatives. As a percentage of
net sales, selling, general and administrative expenses decreased slightly to
10.8% in the first six months of 1998 as compared to 10.9% in the first six
months of 1997.
 
  Research, development and engineering expenses increased to $109 million in
the first six months of 1998 as compared to $92 million in the first six
months of 1997, primarily due to expenditures for new product development.
 
  Interest expense for Case's industrial operations was $44 million for the
first six months of 1998, $9 million higher than the same period of 1997. The
increase in interest expense was due to higher average debt levels during the
first six months of 1998 as compared to the first six months of 1997.
 
  The consolidated effective income tax rates of 31% for the first half of
1998 and 32% for the first half of 1997 were lower than the U.S. statutory
rate of 35% primarily due to tax benefits associated with the Company's
foreign sales corporation, research and development tax credits and reductions
in the tax valuation reserves in certain foreign jurisdictions, partially
offset by state income taxes and foreign income taxed at different rates.
 
CREDIT OPERATIONS
 
  Net income for the first six months of 1998 was $37 million as compared to
$39 million for the first six months of 1997. The $2 million decrease in year-
over-year net income is primarily due to increased interest expense as a
result of higher average on-book receivables, as well as increased
depreciation of equipment on operating leases. These amounts were partially
offset by higher earnings as a result of increased levels of on-balance-sheet
receivables, including higher lease income from operating leases.
 
  Case Credit reported total revenues of $156 million for the first six months
of 1998 and $126 million for the first six months of 1997. Finance income
earned on retail notes and finance leases increased to $62 million in the
first six months of 1998 as compared to $46 million for the same period in
1997, primarily due to increased levels of on-balance-sheet receivables. In
addition, operating lease income increased $12 million to a total of $26
million for the first six months of 1998, reflecting the growth in Case
Credit's operating lease portfolio.
 
  Interest expense for the first six months of 1998 was $60 million, up $16
million from the $44 million reported in the first six months of 1997. The
increase in interest expense resulted from higher average debt levels during
the first six months of 1998 as compared to the first six months of 1997,
primarily due to the growth in Case Credit's on-balance-sheet receivables and
increased equipment on operating leases.
 
  Operating expenses increased $14 million to a total of $39 million in the
first six months of 1998 as compared to the first six months of 1997. This
increase primarily resulted from higher year-over-year depreciation expense
for equipment on operating leases relating to Case Credit's larger operating
lease portfolio, as well as higher operating expenses in support of Case
Credit's growth initiatives.
 
                                      16
<PAGE>
 
  During the first six months of 1998, Case Credit's serviced portfolio of
receivables increased 23% over the same time last year to a record $5.8
billion. Growth in the first six months resulted from Case Credit's focus on
new markets and new products, including retail financing through Case Credit's
European joint venture, Case Credit Europe S.A.S. Gross receivables originated
in the first six months of 1998 increased 36% to $2.1 billion versus the same
period in 1997. During the first six months of 1998, limited-purpose business
trusts organized by Case Credit issued $766 million of asset-backed securities
to outside investors, of which $50 million was issued pursuant to a private
placement. Case Credit has sold $753 million of U.S. and Canadian retail notes
to the trusts in connection with these issuances. During the first six months
of 1997, Case Credit issued $830 million of asset-backed securities to outside
investors. Case Credit had sold $822 million of U.S. and Canadian retail notes
to the trusts in connection with these issuances. The proceeds from the sale
of the retail notes were used to repay outstanding debt and to finance
additional receivables.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  The discussion of liquidity and capital resources focuses on the balance
sheets and statements of cash flows. The Company's operations are capital
intensive and subject to seasonal variations in financing requirements for
dealer receivables and inventories. Whenever necessary, funds provided from
operations are supplemented from external sources.
 
  In the first six months of 1998, cash used by operating activities was $820
million. Cash used by the industrial operations and Case Credit during the
first six months of 1998 was $474 million and $346 million, respectively. The
net cash used by operating activities primarily resulted from increased levels
of wholesale receivables and inventory, partially offset by net income and
depreciation and amortization. The increase in wholesale and retail
receivables reflects higher levels of actual sales volumes, as well as
increased levels of on-balance-sheet receivables as part of Case Credit's
growth initiatives. Inventories have increased since December 31, 1997, due to
growth in the Company's Latin American region, the impact of 1997 acquisitions
and increased inventory for impending third quarter shipments to the former
Soviet Union. Cash used by operating activities was $291 million in the first
six months of 1997. This use of cash primarily reflects increased inventories
and retail receivables, offset by net income and depreciation and
amortization.
 
  Cash used by investing activities was $277 million in the first six months
of 1998. During the first half of 1998, the Company expended $49 million for
property, plant and equipment in comparison to $36 million in the first half
of 1997. Cash used by Case Credit was $189 million versus $52 million for the
comparable period of 1997, reflecting increased year-over-year expenditures
for equipment on operating leases due to the growth in Case Credit's operating
lease portfolio. Also during the first six months of 1998, the Company
expended approximately $40 million to acquire certain assets of the Tyler
Industries division of IBOCO, Inc., a designer, manufacturer and distributor
of a complete line of chemical and fertilizer sprayers and applicators.
 
  Net cash provided by financing activities was $961 million for the first
half of 1998 and was primarily used to support increased levels of receivables
and inventories. During the first six months of 1998, Case Credit issued an
aggregate of $279 million of medium-term notes pursuant to a shelf
registration filed with the Securities and Exchange Commission in September of
1997. The net proceeds from the medium-term note issuances will be used to
fund Case Credit's growth initiatives and for other corporate purposes,
including the repayment of indebtedness. During the first six months of 1997,
net cash provided by financing activities was $440 million, primarily due to
increases under the Company's short-term debt and revolving credit facilities
to fund Case Credit's growing portfolio of receivables.
 
  Total debt at June 30, 1998, was $3,731 million, $2,365 million of which
related to Case Credit. The consolidated debt to capitalization ratio, defined
as total debt divided by the sum of total debt, stockholders' equity and
preferred stock with mandatory redemption provisions, was 60.7% at June 30,
1998, and the Company's industrial debt to capitalization ratio was 36.1%. The
consolidated and industrial ratios at December 31, 1997, were 54.6% and 27.3%,
respectively.

FUTURE LIQUIDITY AND CAPITAL RESOURCES
 
  The Company has various sources of future liquidity including asset-backed
securitization markets, public debt offerings and other available lines of
credit.
 
  The Company recently announced that it would accelerate its four million
share repurchase program, authorized by the Company's Board of Directors in
May 1997, and substantially complete the buy back in the third quarter of
1998. On July 10, 1998, the Company's Board of Directors authorized a second
program for the purchase from time to time of up to eight million shares of
the Company's Common Stock. The purchase of Case Common Stock under these
programs is at the Company's discretion, subject to prevailing financial and
market conditions.
 
OUTLOOK
 
  The market conditions for Case's agricultural and construction equipment and
financial services businesses vary by regions of the world.
 
  Sales of agricultural equipment have been strong in North America and Latin
America, although weakness continues in the Asia Pacific region and parts of
Europe. Commodity prices, which are comparably lower, have been affected by
expectations of a strong harvest and could possibly impact net farm income.
However, farmers' balance sheets are in good condition in North America. In
other regions of the world, additional factors such as the need for self-
sufficiency or adoption of advanced equipment and farming practices support
continued demand.
 
  The worldwide construction equipment market is led by excellent demand in
North America as a result of continued strong housing starts and a favorable
interest rate environment. This outlook is strengthened by increased spending
as a result of the new U.S. highway bill. In Europe, economic conditions
continue to show signs of improvement, and the construction sectors are
beginning to reflect that improvement. In the Asia Pacific region, overall
economic conditions have resulted in a weaker Australian dollar, which has
impacted the overall economy and construction activity there. In Latin
America, economic conditions in Brazil and Mexico are greatly improved and
retail sales of construction equipment are expected to continue to show
strength year-over-year.
 
  The information included in the "Outlook" section represents forward-looking
statements and involves risks and uncertainties that could cause actual
results to differ materially from those in the forward-looking statements. The
Company's outlook is predominantly based on its interpretation of what it
considers key economic assumptions. Crop production and commodity prices are
strongly affected by weather and can fluctuate significantly. Housing starts
and other construction activity are sensitive to interest rates and government
spending. Some of the other significant factors for the Company and its
customers include general economic and capital market conditions, the cyclical
nature of its business, foreign currency movements, the Company's and its
customers' access to credit, political uncertainty and civil unrest in various
areas of the world, pricing, product initiatives and other actions taken by
competitors, disruptions in production capacity, excess inventory levels, the
effect of changes in laws and regulations (including government subsidies and
international trade regulations), changes in environmental laws, and employee
and labor relations. Further information concerning factors that could
significantly impact expected results is included in the following sections of
the Company's Form 10-K Annual Report for 1997, as filed with the Securities
and Exchange Commission: Business--Employees, Business--Environmental Matters,
Business--Significant International Operations, Business--Seasonality and
Production Schedules, Business--Competition, Legal Proceedings, and
Management's Discussion and Analysis of Financial Condition and Results of
Operations.
 
DERIVATIVES
 
  The Company uses derivative financial instruments to manage its foreign
currency and interest rate exposures. Case does not hold or issue financial
instruments for trading purposes. For information regarding Case's foreign
currency and interest rate risk management, reference is made to Item 7 and
Note 11 to the Case Financial Statements in the Company's 1997 Annual Report
on Form 10-K. There has been no material change in the Company's market risk
exposures that affect the quantitative and qualitative disclosures as
presented as of December 31, 1997.

- ---------                                                               
capacity of the Plant, the Sponsors agree as follows:
 
     (a) Maintenance of Current Capacity.  Except as the Sponsors shall
         -------------------------------                               
otherwise agree, each year, as necessary, the Sponsors shall cause each Partner
to contribute 50% of any capital necessary to maintain  the capacity of the

the capacity of the Plant beyond Theoretical Current Capacity for any Units at
the Plant or to cause or permit the Plant to produce in excess of Theoretical
Current Capacity for any Units at the Plant but shall not have the right to make
Unilateral Investments or take any other action that reasonably would be
expected to result in a decrease of the Theoretical Current Capacity for any
Units at the Plant or causes the Plant to produce less than demonstrated
production for the prior year.  If any five-year forecast described at the
beginning of this Section 2.08 implies sustained production by the Plant in
                  ------------                                             
excess of Theoretical Current Capacity for any Units at the Plant, the Project
Manager shall perform an analysis of the expenses, investments or costs
(including ongoing operating costs such as employee overtime costs) required to
increase the production capacity at the Plant so as to eliminate persistent
production shortfalls. Based on that analysis, the Sponsors shall make such
investments in the Plant's production capacity as are reasonably necessary and
are consistent with the investment objectives at the Sponsors and prudent
business judgment.  Each Sponsor shall have the right, but not the obligation,
to jointly fund the expenses, costs and/or investments in connection with the
increase of the Plant's capacity (a "Jointly Funded Investment").  In the event
                                     -------------------------                 
of a Jointly Funded Investment, each Sponsor shall pay one-half of the aggregate
costs, expenses and/or investments related to such Jointly Funded Investment.
If  the Sponsors do not agree to a Jointly Funded Investment, then either
Sponsor shall have the right, but not the obligation, to unilaterally make such
investments and incur such costs and expenses in connection with the increase to
the Plant's Theoretical Current Capacity for any Units at the Plant (a

by the Sponsor making such investments and/or incurring such costs and expenses
and shall not be considered part of the Partnership's expenses, assets or
liabilities.

     (c) A Sponsor may utilize the additional capacity of the Plant created by a
Unilateral Investment of the other Sponsor only upon payment to the other
Sponsor of an amount equal to (A)

                                      -7-
<PAGE>
 
(i) one-half of the average of (x) the acquisition costs to the other Sponsor of
the assets acquired (and/or the amount of capitalized expenditures) in
connection with such Unilateral Investment and (y) the then current book value
of such assets (and/or capitalized expenditures), plus (ii) one-half of the one-
time Partner Only Expenses required for installation of such capacity, plus
(iii) an amount sufficient to provide the other Sponsor with a [CONFIDENTIAL
INFORMATION CONTAINED HERE HAS BEEN OMITTED AND FILED SEPARATELY WITH THE
SECURITIES AND EXCHANGE COMMISSION] on the Unilateral Investment or (B) such
other amount as the Sponsors shall agree. To the extent that a Sponsor utilizes
the additional capacity created by the other Sponsor's Unilateral Investment by
payment of the foregoing amount, the assets in connection with such expansion
shall be deemed equal contributions of the Partners to the Partnership and shall
be reflected in the Partnership's books accordingly. If one Sponsor makes a
minimal and infrequent use of the additional capacity created by a Unilateral
Investment of the other Sponsor, such first Sponsor shall not be required to
invest in such Unilateral Investment solely because of such minimal and
infrequent use; provided, however, that in such event, such first Sponsor shall

reasonably compensate the other Sponsor for such use and shall take such other
actions as determined by the Partner Representatives.

requires on its engine purchases.  The Sponsors shall permit the Plant to
install such items on engines that have been assembled, tested and painted for
Cummins.

     (b) Cummins' Use of Upfit Center.  For so long as Cummins is the only party
         ----------------------------                                           
requiring the use of the Upfit Center at the Plant, Cummins shall be solely
responsible for the amount of any expenditures necessary to maintain and operate
the same.  Any assets acquired by Cummins in connection with such Upfit Center
shall be carried on Cummins' books and shall not be considered assets of the
Partnership.

     (c) Joint Use of Upfit Center.  If Case decides to use a portion of the
         -------------------------                                          
Upfit Center at the Plant, Case agrees to reimburse Cummins for an amount equal
to the average of the sum of one-half of the cost of the asset purchases after
June 25, 1986, and one-half of the current book value of such assets, or such
other amount as Cummins and Case may agree.

     (d) Assets of Upfit Center.  To the extent Cummins and Case participate
         ----------------------                                             
equally in the capital requirements of the Upfit Center, the assets acquired
shall be deemed equal contributions of the Partners to the Partnership and shall
be reflected as such in the Partnership books.

the Partnership shall continue to supply Licensed Engines  not certified as
complying with the emissions standards of any governmental authority for diesel
engines as long as the demand for such Licensed Engines continues, unless it
becomes economically unfeasible to do so.  If at any time a demand for such non-
certified Licensed Engines exists, and it is uneconomical for the Partnership to
produce such Licensed Engines, the Partnership Representatives shall meet and
attempt to reach an equitable solution.  If they are unable to agree on a
solution, the dispute shall be resolved in accordance with Section 6.02.

          (2) If production of such engine or component by the Partnership
     requires any capital investment or any other costs, the Funding Sponsor
     shall bear full responsibility for the same.

          (3) The other Sponsor shall not be entitled to purchase such engine or
     component from the Partnership unless:

Licensed Engine.  The Sponsors acknowledge that a principal objective is to
develop engines that will satisfy emissions standards prescribed by various
governmental authorities, including the United States Environmental Protection
Agency.  The parties further acknowledge that it will become necessary for the
4B Engine to achieve compliance with United States Environmental Protection
Agency "Tier II" emissions standards when those standards become applicable to
the 4B Engine in coming years.  Cummins has assured Case that it will be
possible for the Partnership to produce, without substantial additional capital
expenditures to the Partnership on the part of Case, a 4B Engine that achieves
compliance with the aforementioned emissions standards while also achieving
performance approaching that of the Encore engine ("Tier II Compliance").  As of

pursuant to the terms hereof and of the other Related Agreements or agreements
subsequently entered into in furtherance hereof to the extent required to cover
Case's share of the capital expenditures necessary for the 4B Engine to achieve
Tier II Compliance; provided, however, that if at any time the Partnership

SECURITIES AND EXCHANGE COMMISSION], Case shall not be required to make
payments to cover its share of any portion of such excess except to the extent
that Case is given the opportunity to review and approve the proposed excess
expenditures prior to the time the Partnership commits to such expenditures.

     (f) ENCORE ENGINE.  Case shall participate in the D Family (8.8 liter)

orders, (ii) the Theoretical Current Capacity of each of the Capacity Products
for such year, (iii) the Upfit Center Capacity for such year and (iv) the best
estimate of the Take, and where applicable, the Worldwide Take for each of Case
and Cummins for such year (the "Planned Take Percentage") and such other cost

allocation estimates as may be required under the Related Agreements.  The
General Manager shall provide information necessary to support each Partner's
planning process promptly upon request from such Partner.  In addition, the
proposed operating plan shall itemize Base Capital Expenditures project by
project, and each project shall describe cash requirements for the year of the
plan and for the life of the project and the proposed Unilateral Investments of
each Partner's Parent. The proposed operating plan shall also provide an
analysis of expected Working Capital levels for each month-end and cash
requirements for each month of the applicable calendar year.  Upon completion,
the proposed operating plan shall be submitted to the Partner Representatives
for review.

     (b)  Review.  The Partner Representatives shall discuss and try to approve
          ------                                                               
the proposed operating plan as soon as possible.  A Partner Representative shall
not reject a proposed operating plan on the basis of a proposed Unilateral
Investment contained therein unless such Partner Representative reasonably
believes that such proposed Unilateral Investment will adversely affect the
Partnership or the Theoretical Current Capacity of any Capacity Products.  If
the proposal is acceptable to both Partner Representatives, they shall submit
it, along with any recommended modifications, to the Partnership Committee for
review and approval.  If the Partner Representatives are unable to agree within
two weeks after the proposed operating plan is presented to them by the General
Manager, or such additional time as they may determine, the proposed operating
plan, along with any recommended modifications and points of disagreement, shall
be submitted to the officers at Cummins and Case, acting as executive vice
presidents or the equivalent, who are generally 

                                    Ex. C-6
<PAGE>
 
responsible for Partnership matters. Such officers shall discuss and try to
approve the proposed operating plan. If they agree, they shall submit the
proposed operating plan, along with any recommended modifications, to the
Partnership Committee for review and approval. If such officers are unable to
agree after two weeks, or such additional time as they may determine, the
proposed operating plan, along with any recommended modifications and the points
of disagreement, shall be submitted to the chief executive officer of Cummins
and the chief executive officer of Case. The chief executive officers shall
discuss and try to approve the proposed operating plan. If they agree, they
shall submit the proposed operating plan, along with any recommended
modifications, to the Partnership Committee for review and approval. If the
chairman and the chief executive officer are unable to agree after two weeks, or
such additional time as they may determine, the matter shall be resolved in a
manner to be determined by the Partners.

     (c)  Capital Projects.  Base Capital Expenditures included in any proposed

the extent they (i) are consistent with stated Partnership objectives, (ii) are
reasonably required for the efficient operation of the Partnership and (iii) do
not exceed a reasonable level, either as to individual projects or as to all
capital projects taken together.  Unless the Partnership Committee otherwise
expressly agrees, with respect to any capital project included in a proposed
plan, the following provisions shall apply:

          (1)  Approval of the project shall extend to approval of the total
     spending level specified in the plan for the life of the project.

          (2)  Approval of the project shall extend to approval of the spending
     level specified in the plan for the applicable year; provided, however,
                                                          --------  ------- 
     that as actually implemented such spending level may deviate, without
     further approval, by 10% or $200,000, whichever is greater, so long as:

               (A)  the deviation is reasonably necessary as a result of
          unforeseen circumstances; and

               (B)  overall capital spending during the applicable year does not
          exceed the total specified in the corresponding Annual Operating Plan.

          (3) Notwithstanding anything to the contrary contained in this Section
                                                                         -------

     approved Annual Operating Plan, and are subsequently determined to be
     reasonably necessary for the operation of the Plant, shall require the
     approval of both Sponsors prior to implementation of any such capital
     project.

          (4)  Separate approval shall be required under subsequent operating
     plans for annual spending levels on approved capital projects in the
     corresponding years; provided, however, that approval shall not be withheld
                          --------  -------                                     
     if the spending level reasonably approximates the spending level projected
     for such year when the project was initially approved and if the 

                                    Ex. C-7
<PAGE>
 
     Project Manager reaffirms that such spending level is still reasonable
     under the circumstances.

     (d)  Approval.  Any proposed operating plan shall become effective
          --------                                                     
according to its terms, including any deviation permitted under Section
                                                                -------

be unreasonably withheld or delayed.  If the Partnership Committee does not
approve an annual operating plan in its entirety, the Partnership Committee
shall submit the portion of such plan (a "Partially Approved Plan") agreed upon
                                          -----------------------              
to the Project Manager for implementation.

     (e)  Interim Plan.  If, by December 15 of any year, the Partnership
          ------------

the Project Manager shall implement, and both Partners shall cooperate in a
timely fashion to implement and abide by the most recent version of the proposed
operating plan offered by the Project Manager (the "Interim Plan") , excluding
                                                    ------------              
items specifically not agreed by the Partners.  Such Interim Plan shall remain
in effect until the earlier of (i) the end of the year in which it is intended
to apply or (ii) when the Partnership Committee approves an operating plan for
the year, subject to any adjustments in Plant operation that may be necessary
after plan approval.  An Interim Plan shall be superseded by a Partially
Approved Plan to the extent of the provisions in the Partially Approved Plan.

     SECTION 6.06 SECTION 704(c) ALLOCATIONS.
                  -------------------------- 

     (a) Statement of Principle.  The transfers of interest in the Partnership
         ----------------------                                               
pursuant to Case's reorganization resulted in terminations for federal income
tax purposes under Internal Revenue Code Section 708, and deemed contributions
of appreciated property by Cummins Holding subject to Code Section 704(c) and
Treasury Regulations Section 1.704-3 (the "704(c) Regulations").  The 704(c)
                                           ------------------               
Regulations allow the Partners to agree to a reasonable method of reflecting the
difference between the tax basis and value of property deemed contributed by
Cummins Holding on the date of the tax termination.  The intent of the Partners
is, to the extent permitted by applicable tax law, to allocate to Cummins
Holding the same depreciation it would have been allocated if there had been no
tax termination of the Partnership.

     (b) Treatment of Undivided Interests.  For purposes of applying the 704(c)
         --------------------------------                                      
Regulations, each Partnership asset (or group of assets permitted to be
aggregated under the 704(c) Regulations) existing on the date of the tax
termination shall be treated as giving rise to two items of Property: the 50%
undivided interest deemed contributed by Cummins Holding (the "Cummins 708
Property") and the 50% undivided interest deemed contributed by Case Holding
(the "Case 708 Property").

     (c) Choice of 704(c) Method.  The Partnership shall use the traditional
         -----------------------                                            
method with curative allocations provided in (S) 1.704-3(c) of the 704(c)
Regulations with respect to the Cummins 708 Property and Case 708 Property, as
further provided in this Section 6.06.
                         ------------ 

     (d)  Regular Depreciation.
          -------------------- 

          (1) Depreciation and cost recovery deductions and gains and losses
     with respect to Cummins 708 Property taken into account for regular tax
     purposes shall first be allocated to Case Holding until Case Holding is
     allocated 50% of the amount that would have been allocated if the Cummins
     708 Property had a tax basis equal to fair market value.  Any remaining
     depreciation and cost recovery deductions and gains and losses with respect
     to the Cummins 708 Property shall be allocated to Cummins Holding.

          (2) Depreciation and cost recovery deductions and gains and losses
     with respect to the Case 708 Property taken into account for regular tax
     purposes shall be allocated 50% to each Partner, except that the
     Partnership shall make curative allocations to Case Holding of a portion of
     the amounts otherwise allocable to Cummins Holding.  The amount of the
     curative allocation shall be the lesser of (A) the amount needed to reduce
     Cummins Holding's allocation of depreciation and cost recovery deductions
     and gains and losses with respect to Cummins 708 Property and Case 708
     Property to the amount Cummins Holding would have been allocated if there
     had been no tax termination of the Partnership, and (B) the amount needed
     to increase Case Holding's allocation of such amounts to the amount Case
     Holding would have been allocated if the Cummins 708 Property had had a tax
     basis equal to fair market value on the date of the tax termination.  The
     amount in clause (A) of the preceding sentence shall be determined on a
     cumulative basis from July 15, 1994.

     (e)  AMT Depreciation.
          ---------------- 

          (1) Depreciation and cost recovery deductions and gains and losses
     with respect to Cummins 708 Property taken into account for alternative
     minimum tax purposes shall first be allocated to Case Holding until Case
     Holding is allocated 50% of the amount that would have been allocated if
     the Cummins 708 Property had a tax basis equal to fair market value. Any
     remaining depreciation and cost recovery deductions and gains and losses
     with respect to the Cummins 708 Property shall be allocated to Cummins
     Holding.

          (2) Depreciation and cost recovery deductions and gains and losses
     with respect to the Case 708 Property taken into account for alternative
     minimum tax purposes shall be allocated 50% to each Partner, except that
     the Partnership shall make curative allocations to Case Holding of a
     portion of the amounts otherwise allocable to Cummins Holding.  The amount
     of the curative allocation shall be the lesser of (A) the amount needed to
     reduce Cummins Holding's allocation of depreciation and cost recovery
     deductions and gains and losses with respect to Cummins 708 Property and
     Case 708 Property to the amount Cummins Holding would have been allocated
     if there had been no tax termination of the Partnership, and (B) the amount
     needed to increase Case Holding's allocation of such amounts to the amount
     Case Holding would have been allocated if the Cummins 708 Property had had
     a tax basis equal to fair market value on the date of the tax termination.
     The amount in clause (A) of the preceding sentence shall be determined on a
     cumulative basis from the date of this Amendment.

     (f) Variation by Agreement.  The Partners may vary the tax allocations
         ----------------------                                            
resulting from the preceding paragraphs of this Section 6.06 if the Partners
                                                ------------                
agree that a different allocation would be fairer or would more closely comply
with the requirements of the Internal Revenue Code and regulations.

Partners shall be in equal shares; provided, however, that the amount of any
                                   --------  -------                        
capital contribution required to be made by a Partner which has not been made
may be deducted from the amount of any distribution to which such Partner would
otherwise be entitled.  Except as otherwise provided in Section 5.02(b), the
                                                        ---------------

                                                             SPONSORS' AGREEMENT

                          THEORETICAL CURRENT CAPACITY

     Concurrent with the preparation of the Annual Operating Plan for each
calendar year, the Sponsors shall also determine the Theoretical Current
Capacity of the Plant for such year for Licensed Engines, Head Sub-Assembly,
Cummins Products, Case Products, each of the Components (each, a "Unit" and,
                                                                  ----      
collectively, the "Capacity Products") in accordance with the provisions of this
                   -----------------                                            
Exhibit D.  The "Theoretical Current Capacity" for each Unit shall equal the
- ---------        ----------------------------                               
number determined by application of the following formula:

[CONFIDENTIAL INFORMATION CONTAINED HERE HAS BEEN OMITTED AND FILED SEPARATELY
WITH THE SECURITIES AND EXCHANGE COMMISSION].
 
     1.   In determining Theoretical Current Capacity for a Unit in any year,
the Sponsors shall maintain the operation of the Plant in a practical and
efficient manner.  In determining what is practical and efficient in operating
the Plant, the Sponsors shall consider existing policies and procedures of, and
past practices for, the operation of the Plant and the impact of any changes to
such policies and procedures and past practices.  Each Sponsor may also consider
its various economic alternatives (e.g., deciding whether to incur operating
                                   ----                                     
expenses or capital expenditures) to achieve the goals of each Sponsor with
respect to Theoretical Current Capacity levels for a Unit.

     2.   At the time of determination of Theoretical Current Capacity for a
Unit, the Sponsors shall provide five-year estimates of their demand for such
Unit from the Plant.  Each estimate provided by Case shall estimate Case's
entire worldwide requirements for Capacity Products.  Each estimate provided by
Cummins shall estimate Cummins  requirements for Capacity Products at the Plant.
For each calendar year, the sum of the estimated demand of Case and Cummins of
Capacity Products shall equal the "Aggregate Demand."  The Sponsors shall make
                                   ----------------                           
the determinations in this Exhibit D in a manner that both (i) is consistent
                           ---------                                        
with the requirements of paragraph 1 above and (ii) endeavors to avoid the
payment of any fees described in paragraph 4 below by either Sponsor.

     3.     Each Sponsor shall also estimate the number of its purchases of
Capacity Products from the Partnership for such year in the Annual Operating
Plan.

     4.   In any year a Sponsor shall pay a Utilization Fee to the other Sponsor
if the first Sponsor purchases a number of engines included in Capacity Products
that exceeds the sum of (i) 50% of the Theoretical Current Capacity for such
year for such engines, plus (ii) Underutilized Capacity for such engines of the
other Sponsor at the Plant plus (iii) with respect to Cummins (in order to
consider the impact of Transferred Engines actually purchased by Case in the
Theoretical Current Capacity available to Cummins), the positive amount (if any)
by which the number of Transferred Engines actually purchased by Case and its
Affiliates exceeds Case's Underutilized Capacity.  [CONFIDENTIAL INFORMATION

AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION].
"Underutilized Capacity" with respect to a Sponsor in any year shall mean the
- -----------------------
positive amount, if any, by which (x) 50% of Theoretical Current Capacity for
such year for engines included in Capacity Products exceeds (y) the number of
such engines purchased by such Sponsor in such year from the Plant. For purposes
of calculating the Utilization Fee, in no event shall the Theoretical Current
Capacity available to Cummins in a calendar year be less than the sum of (x) 50%
of Theoretical Current Capacity for such year and (y) the number of Transferred
Engines actually purchased by Case in such year.

     5.   If actual production with respect to any Unit exceeds Theoretical
Current Capacity with respect to such Unit in any calendar year, actual
production for such Unit shall become Theoretical Current Capacity for such Unit
for the same calendar year.  Theoretical Current Capacity with respect to any
Unit shall also be increased by the Sponsors in any year as a result of any
Jointly Funded Investment or if a Sponsor jointly funds the other Sponsor's
Unilateral Investment in accordance with Section 2.08(c) of the Sponsors'
                                         ---------------                 
Agreement.  If a Sponsor makes a Unilateral Investment, the capacity created by
such Unilateral Investment shall not be included in the calculation of
Theoretical Current Capacity and such Unilateral Investment shall reduce the
number of Capacity Products subject to the Utilization Fee by the amount by
which capacity is increased by such Unilateral Investment.

     6.   Any Utilization Fee accrued for a calendar year shall be paid by the
relevant Sponsor, net of any Utilization Fee owing to it, on or before January
31 of the calendar year immediately after such year.

burned in a direct injection compression ignition engine without major revision
to the component systems design, but shall not cover spark ignition (Otto Cycle)
engines or engines employing fuels which require major component system redesign
or major change to the engine component materials. Cummins shall allow Case to
reasonably participate in Cummins' internal long range engine planning process
(product preceding technology), and Cummins shall use reasonable efforts to
accommodate the reasonable interests of Case and the Partnership in such
planning process as expressed through Case's participation in such process.

       SECTION 2.02    TECHNICAL INFORMATION.  Cummins shall provide the
                       ---------------------

Technical Assistance Agreement that is within Cummins' capability to provide and
is, in the judgment of Cummins, reasonably useful and necessary for (i)
producing such Licensed Engines and Components at the Partnership, Case's
Manufacturing Affiliate and Case's North American plant, if such plants are
established pursuant to Sections 2.06(a) and (b) of the Sponsors' Agreement,
                        ----------------     ---                            
(ii) keeping such Licensed Engines technologically current, (iii) adapting such
Licensed Engines to changing requirements, with regard to applications or uses
of Licensed Engines or as may be required by any applicable governmental
regulations, (iv) keeping such Licensed Engines competitive with regard to cost
and performance, and (v) providing information on Cummins' Licensed Engine
advanced engine technology.

       SECTION 2.03    SUPPORT SERVICES.  Cummins shall provide such assistance
                       ----------------

  (k)  advanced design activities.

       The Partnership recognizes the benefit of limiting form, fit and function
design changes. When such changes are required, Cummins shall advise Case as
early as possible in the design process to understand impacts on Case products.
Cummins shall use reasonable efforts to accommodate any concerns of Case prior
to issuance of any engineering release directing the implementation of such
engineering changes.  Any disagreements between Case and Cummins concerning
engineering changes shall be resolved by the Product Family Chief Engineer
(specified within Cummins Engineering Std 99043).  Cummins shall notify the
Partnership, Case and Case Affiliates promptly of any corrections to the
Technical Information furnished hereunder.

Cummins and the Partnership shall not implement any engineering change that
would:  (i) increase the Materials Costs of Licensed Engines or Components to be
sold to Case or its Affiliates by more than [CONFIDENTIAL INFORMATION CONTAINED
HERE HAS BEEN OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
COMMISSION] without the prior approval of Case; or (ii) require Case to modify a
product in order to install a Licensed Engine in such product without giving
Case 20 days prior written notice of such engineering change.  If Case gives the
Partnership written notice, before such change is implemented, that such change
is unacceptable, and if thereafter Case and Cummins are unable to resolve such
engineering change dispute, the matter shall be referred to the Partnership
Committee and resolved in accordance with the procedures set forth in Section
6.02 of the Sponsors' Agreement (excluding the first sentence thereof).

years covered by any such plan shall be reasonably detailed with only the first
year considered firm as approved within Cummins' annual operating plan.  The
parties shall make available adequate resources to meet and manage the agreed

       In support of such technical planning, Case and Cummins agree to
participate together in a periodic planning process known as the "Case/Cummins
Midrange Technical Steering Committee."  The Case/Cummins Midrange Technical
Steering Committee, comprised of Case and Cummins technical leaders, shall
regularly review product and project technical plans and adjust such plans as
necessary on a short-term and long-term basis to meet the business needs of
Case, Cummins and the Partnership. If  the members of the Case/Cummins Midrange
Technical Steering Committee do not agree on any such product plans, such
disagreement shall be presented to the Technical Committee for resolution.
