ITEM 1. BUSINESS
 
     and
 
ITEM 2. PROPERTIES
 
     Burlington Northern Inc. (BNI) was incorporated in Delaware in 1981 as part
of a holding company reorganization. BNI and its majority-owned subsidiaries
(collectively BN) are primarily engaged in the rail transportation business. The
principal subsidiary is Burlington Northern Railroad Company (Railroad). BN
Leasing Corporation, a wholly owned subsidiary of BNI, was formed during 1989 to
acquire railroad rolling stock and other equipment necessary for the
transportation and other business affairs of BN.
 
  Railroad transportation
 
     Railroad operates the largest railroad system in the United States based on
miles of road and second main track, with approximately 24,500 total miles at
December 31, 1993. The principal cities served include Chicago, Minneapolis-St.
Paul, Fargo-Moorhead, Billings, Spokane, Seattle, Portland, St. Louis, Kansas
City, Des Moines, Omaha, Lincoln, Cheyenne, Denver, Fort Worth, Dallas, Houston,
Galveston, Tulsa, Wichita, Springfield (Missouri), Memphis, Birmingham, Mobile
and Pensacola.
 
     During 1993, BN refined Railroad's customer oriented business units by
creating smaller, more focused business units. The following table presents BN's
revenue information by Railroad business unit, and includes reclassification of
prior-year information to conform to current year presentation.
 
     Percent of revenues was calculated before consideration of shortline
payments and other miscellaneous revenues. The principal contributors to rail
transportation revenues were as follows (revenues and revenue ton miles in
millions, carloadings in thousands):

  Coal
 
     The transportation of coal is Railroad's largest source of revenues,
accounting for approximately one-third of the total. Based on carloadings and
tons hauled, Railroad is the largest transporter of Western low-sulfur coal in
the United States. Over 90 percent of Railroad's coal traffic originated in the
Powder River Basin of Montana and Wyoming during the three years ended December
31, 1993. These coal shipments were destined for coal-fired electric generating
stations primarily in the North Central, South Central and Mountain regions of
the United States with smaller quantities exported.
 
     Railroad also handles increasing amounts of low-sulfur coal from the Powder
River Basin for delivery to markets in the eastern and southeastern portion of
the United States. The low-sulfur coal from the Powder River Basin is abundant,
inexpensive to mine and clean-burning. Since the Clean Air Act of 1990 requires
 
                                        2
<PAGE>   5
 
power plants to reduce harmful emissions either by burning coal with a lower
sulfur content or by installing expensive scrubbing units, opportunities for
increased shipments of this low-sulfur coal still exist.
 
  Agricultural Commodities
 
     Based on carloadings and tons hauled, Railroad is the largest rail
transporter of grain in North America. Railroad's system is strategically
located to serve the Midwest and Great Plains grain producing regions where
Railroad serves most major terminal, storage, feeding and food-processing
locations. Additionally, Railroad has access to major export markets in the
Pacific Northwest, western Great Lakes and Texas Gulf regions as well as direct
entry to consuming markets in southern Mexico through its Protexa Burlington
International affiliate.
 
  Intermodal
 
     Intermodal transportation moves traffic on specially designed flatcars or
doublestack equipment which competes with motor carriers. Railroad's intermodal
transportation system integrates the movement of approximately 46 daily trains
operating between 30 rail hubs and 28 satellite rail hubs (Railroad-operated
marshalling points for trailer/container movements). These operations are
strategically located across Railroad's rail network and also serve major
distribution centers outside BN's system. Strategic alliances have been formed
to enhance Railroad's market access both with other railroads and with major
truck transportation providers.
 
  Forest Products
 
     The Forest Products business unit is primarily comprised of lumber,
plywood, pulpmill feedstock, wood pulp and paper products. These products
primarily come from the Pacific Northwest, upper Midwest and Southeast areas of
the United States.
 
  Chemicals
 
     The Chemicals business unit is comprised of fertilizer, petroleum and
chemical commodities as well as Railroad's environmental logistics business.
Primary origin markets for Railroad include the Gulf Coast, the Pacific
Northwest, and various Canadian ports of entry. Environmental logistics is an
area of significant opportunity as municipalities exhaust their traditional
disposal sources and must increasingly transport their waste longer distances.
 
  Consumer Products
 
     Products included in Railroad's Consumer Products business unit represent a
wide variety of commodities. Some of the major products in this group are food
products, beverages, frozen foods, canned foods, appliances and electronics.
Because this business unit handles a wide variety of consumer goods, the
business unit performance typically mirrors the country's economy.
 
  Minerals Processors
 
     Commodities in this group include clays, cements, sands and other minerals
and aggregates. This group services both the oil and construction industries.
 
  Iron & Steel
 
     The Iron & Steel business unit handles virtually all of the commodities
included in or resulting from the production of steel. Taconite, an iron ore
derivative produced in northern Minnesota, scrap steel and coal coke are the
business unit's primary input products, while finished steel products range from
structural beams and coil to wire and nails.

  Vehicles & Machinery
 
     The Vehicles & Machinery business unit is responsible for both domestic and
international vehicle manufacturers as well as an assortment of primary and
secondary markets for heavy machinery. Through the development and
implementation of Autostack technology (using containers to move motor
vehicles), Railroad is redefining transit time and ride quality. Heavy machinery
includes primary markets for aircraft, construction, farm and railroad equipment
and secondary markets for used equipment. The business unit is also responsible
for military and other miscellaneous traffic for the United States government.
 
  Aluminum, Non-Ferrous Metals & Ores
 
     The Aluminum, Non-Ferrous Metals & Ores business unit handles alumina and
aluminum products, petroleum coke and a variety of other metals and ores such as
zinc, copper and lead.

* Beginning in 1990, BN reduced revenues and mileage for the effects of
  shortline railroads, which complete hauls for BN. In prior years, payments to
  shortline railroads were classified in operating expenses.

  Properties
 
     In 1993, approximately 96 percent of the total ton miles, both revenue and
non-revenue generating, carried by Railroad were handled on its main lines. At
December 31, 1993, approximately 18,828 miles of Railroad's track consisted of
112-lb. per yard or heavier rail, including approximately 10,461 track miles of
132-lb. per yard or heavier rail. Additions and replacements to properties were

     In addition to the owned and leased locomotives identified above, BN
operates 199 freight locomotives under power purchase agreements.
 
     The average age of locomotives and freight cars was 14.5 years and 18.6
years, respectively, at December 31, 1993, compared with 13.5 years and 18.4
years, respectively, at December 31, 1992.
 
     The average percentage of BN's locomotives and freight cars awaiting
repairs during 1993 was 7.4 and 3.3, respectively, compared with 7.4 and 4.1,
respectively, in 1992. The average time between locomotive failures was 67.9
days in 1993 compared with 71 days in 1992.

     During 1993, BN entered into an agreement to acquire 350 new-technology
alternating current traction motor locomotives. BN anticipates reduced
locomotive operating costs as well as an increase in both horsepower and
traction, meaning fewer locomotives will be needed for many freight operations.
BN accepted delivery of one locomotive during 1993 and anticipates delivery of
between approximately 60 and 100 each year from 1994 through 1997.
 
  Employees
 
     BN employed an average of 30,502 employees in 1993 compared with 31,204 in
1992 and 31,760 in 1991. BN's payroll and employee benefits costs, including
capitalized labor costs, were approximately $1.9 billion for each of the years
ended December 31, 1993, 1992 and 1991. Almost 90 percent of BN's employees are
covered by collective bargaining agreements with 14 different labor
organizations.
 
     In October 1991, Railroad entered into an agreement (Crew Consist Agreement
No. 1) with the United Transportation Union (UTU) covering the southern portion
of Railroad's system. Crew Consist Agreement No. 1 provided for crews on most
through-freight trains to consist of one conductor and one engineer and for
crews on all other trains to consist of one brakeman, one conductor and one
engineer.
 
     Under the terms of Crew Consist Agreement No. 1, Railroad offered the
opportunity for voluntary separation from employment in return for severance
payments of up to $60,000 per employee. Remaining conductors or brakemen who, as
a result of Crew Consist Agreement No. 1, were unable to hold a position in
active service, due to relative seniority, were placed on a reserve board.
Employees in reserve status received compensation at a rate equal to either 75
percent of their previous 12-month earnings, or 75 percent of the basic five-day
yard helper rate of pay, whichever is greater, and are required to be available
for return to active service on 15 days' notice. Each UTU member on the southern
portion of Railroad's system received a lump-sum payment of $1,000 upon
ratification of Crew Consist Agreement No. 1.
 
     In May 1993, Railroad entered into an agreement (Crew Consist Agreement No.
2) with the UTU covering approximately 3,400 UTU members in the northern portion
of Railroad's system. Crew Consist Agreement No. 2 provides for crews on most
through-freight trains to consist of one conductor and one engineer and for
crews on all other trains to consist of one brakeman, one conductor and one
engineer. It is similar to Crew Consist Agreement No. 1, covering the southern
portion of Railroad's system. Each UTU member on the northern portion of
Railroad's system received a one-time lump-sum payment of $5,000, pursuant to
Crew Consist Agreement No. 2.
 
     Under the terms of Crew Consist Agreement No. 2, Railroad offered the
opportunity for voluntary separation from employment in return for severance
payments of up to $80,000 per employee. Conductors and brakemen who choose not
to accept the voluntary separation offer can elect volunteer surplus status
pursuant to which they will receive $60,000 to be paid out over a period of 18
to 48 months, as each selects. If such employee has not been recalled to active
service by the time such payments cease upon expiration of the selected period,
such employee will remain in volunteer surplus status, without further
compensation or benefits, until recalled to active service. Employees in
volunteer surplus status may be called back to service only after the
individuals in reserve status, within their own subdivided seniority district,
have been recalled. Remaining conductors and brakemen who, as a result of Crew
Consist Agreement No. 2, are not needed in train service, and who do not elect
one of the above severance options, will be placed on a reserve board.
 
     Employees in reserve status will receive compensation equal to either 75
percent of their previous 12-month earnings, or 75 percent of the basic five-day
yard helper rate of pay, whichever is greater, and are required to be available
for return to active service on 15 days' notice.
 
     In October 1993, the UTU elected to adopt Crew Consist Agreement No. 2 for
those southern portion UTU members who were previously covered by Crew Consist
Agreement No. 1. Crew Consist Agreement No. 2 was implemented on the southern
portion of the Railroad's system during the fourth quarter of 1993. Upon
implementation, each of the approximately 3,300 UTU members on the southern
portion of Railroad's system received a one-time lump-sum payment of $4,000,
which was the incremental difference between the
 
                                        6
<PAGE>   9
 
$1,000 lump-sum payment received following ratification of Crew Consist
Agreement No. 1 and the amount received by UTU members following adoption of
Crew Consist Agreement No. 2.
 
     Railroad will continue to remove excess positions from train service
through the implementation of Crew Consist Agreement No. 2. Approximately 1,350
excess positions have been removed as a result of employees accepting severance
or voluntary surplus payments. Other excess positions have been eliminated and
personnel formerly in those positions have been assigned to reserve boards,
absorbed through additional train starts and/or utilized in quality and safety
initiatives. Based upon its experience under Crew Consist Agreement No. 1,
Railroad anticipates that the number of employees on reserve status will decline
over time.
 
     In July 1993, the American Train Dispatchers Association ratified an April
agreement which will facilitate the consolidation of all dispatching functions
into a centralized train dispatching office in Fort Worth, Texas by the end of
1995.
 
  Competition
 
     The general environment in which BN operates remains highly competitive.
Depending on the specific market, deregulated motor carriers, other railroads
and river barges exert pressure on various price and service combinations. The
presence of advanced, high service truck lines with expedited delivery,
subsidized infrastructure and minimal empty mileage continues to impact the
market for non-bulk, time sensitive freight. The potential expansion of long
combination vehicles could further encroach upon markets traditionally served by
railroads. In order to remain competitive, BN and other railroads continue to
develop and implement technologically supported operating efficiencies to
improve productivity.
 
     As railroads streamline, rationalize and otherwise enhance their
franchises, competition among rail carriers intensifies. BN's primary rail
competitors in the western region of the United States consist of Atchison,
Topeka & Santa Fe Railway Company; Chicago & Northwestern Transportation Company
(C&NW); Southern Pacific Transportation Company; and Union Pacific Railroad
Company (UP). Coal, one of BN's primary commodities, has experienced significant
pressure on rates due to competition from the joint effort of C&NW/UP and BN's
efforts to penetrate into new markets. In addition to the railroads discussed
above, numerous regional railroads and motor carriers operate in parts of the
same territory served by BN.
 
  Environmental
 
     BN's operations, as well as those of its competitors, are subject to
extensive federal, state and local environmental regulation. In order to comply
with such regulation and to be consistent with BN's corporate environmental
policy, BN's operating procedures include practices to protect the environment.
Amounts expended relating to such practices are inextricably contained in the
normal day-to-day costs of BN's business operations.
 
ITEM 3. LEGAL PROCEEDINGS
 
  Wheat and barley transportation rates
 
     In September 1980 a class action lawsuit was filed against Railroad in
United States District Court for the District of Montana (District Court)
challenging the reasonableness of Railroad's export wheat and barley rates. The
class consists of Montana grain producers and elevators. The plaintiffs sought a
finding that Railroad's single car export wheat and barley rates for shipments
moving from Montana to the Pacific Northwest were unreasonably high and
requested damages in the amount of $64 million. In March 1981 the District Court
referred the rate reasonableness issue to the Interstate Commerce Commission
(ICC). Subsequently, the State of Montana filed a complaint at the ICC
challenging Railroad's multiple car rates for Montana wheat and barley movements
occurring after October 1, 1980.
 
     The ICC issued a series of decisions in this case from 1988 to 1991. Under
these decisions, the ICC applied a revenue to variable cost test to the rates
and determined that Railroad owed $9,685,918 in reparations plus interest. In
its last decision, dated November 26, 1991, the ICC found Railroad's total
 
                                        7
<PAGE>   10
 
reparations exposure to be $16,559,012 through July 1, 1991. The ICC also found
that Railroad's current rates were below a reasonable maximum and vacated its
earlier rate prescription order.
 
     Railroad appealed to the United States Court of Appeals for the District of
Columbia Circuit (D.C. Circuit) those portions of the ICC's decisions concerning
the post-October 1, 1980 rate levels. Railroad's primary contention on appeal
was that the ICC erred in using the revenue to variable cost rate standard to
judge the rates instead of Constrained Market Pricing/Stand Alone Cost
principles. The limited portions of decisions that cover pre-October 1, 1980
rates were appealed to the Montana District Court.
 
     On March 24, 1992, the Montana District Court dismissed plaintiffs' case as
to all aspects other than those relating to pre-October 1, 1980 rates. On
February 9, 1993, the D.C. Circuit served its decision regarding the appeal of
the several ICC decisions in this case. The Court held that the ICC did not
adequately justify its use of the revenue to variable cost standard as Railroad
had argued and remanded the case to the ICC for further administrative
proceedings.
 
     On July 22, 1993, the ICC served an order in response to the D.C. Circuits'
February 9, 1993 decision. In its order, the ICC stated it would use the
Constrained Market Pricing/Stand Alone Cost standards in assessing the
reasonableness of BN wheat and barley rates moving from Montana to Pacific Coast
ports from 1978 forward. The ICC assigned the case to the Office of Hearings to
develop a procedural schedule. The parties are now engaged in discovery.

</TABLE>
 
(1) Beginning in 1990, shortline expenses were reported as a reduction of
    revenues. Prior to 1990, these expenses had been included in purchased
    services expense. The reclassification had no effect on net income.
    Previously issued consolidated financial statements were not restated to
    reflect the reclassification.
 
(2) The 1991 pre-tax special charge relates to: (i) restructuring costs for
    reducing surplus crew positions and a management separation pay program,
    (ii) increases in estimated personal injury costs and (iii) increases in
    estimated environmental clean-up costs.
 
(3) During 1991, BN extinguished debt through an early redemption resulting in
    an extraordinary loss, net of income taxes, of $14 million, or $.18 per
    common share. During 1990, BN extinguished debt through


 
                                       12
<PAGE>   15
 
     note exchange agreements and the purchase of certain debentures. The net
     income for the year ended December 31, 1990 includes a resulting
     extraordinary gain, net of income taxes, of $14 million, or $.18 per common
     share.
 
(4)  Results for 1992 reflect the cumulative effect of the change in accounting
     method for revenue recognition, and the cumulative effect of the
     implementation of the accounting standard for postretirement benefits
     (Statement of Financial Accounting Standards (SFAS) No. 106). The
     cumulative effect of the change in accounting method for revenue
     recognition decreased 1992 net income by $11 million, or $.13 per common
     share. The cumulative effect of the change in accounting method for
     postretirement benefits decreased 1992 net income by $10 million, or $.11
     per common share, and had no immediate effect on cash flows.
 
(5)  Results for 1993 include the effects of the Omnibus Budget Reconciliation
     Act of 1993 (the Act) which was signed into law on August 10, 1993. The Act
     increased the corporate federal income tax rate by one percent, effective
     January 1, 1993, which reduced net income by $29 million, or $.32 per
     common share, through the date of enactment.
 
(6)  Beginning in November 1991, shares used in computation of earnings (loss)
     per common share reflect a November 1991 public offering of 10,350,000
     shares.
 
(7)  During 1993, BN adopted SFAS No. 109, "Accounting for Income Taxes." The
     effect of the adoption was to increase the current portion of the deferred
     income tax asset with a corresponding increase in the noncurrent deferred
     income tax liability of $26 million at January 1, 1993. Certain 1992
     balance sheet data was reclassified to conform to the 1993 presentation.
     These reclassifications had no effect on previously reported net income,
     stockholders' equity or cash flows.
 
(8)  The 1991 operating ratio excludes the special charge discussed in note (2)
     above.
 
(9)  Net income used to calculate return on average stockholders' equity
     excludes, in the year of occurrence, the special charge, extraordinary
     items and the cumulative effect of accounting changes.
 
ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS
 
     Management's discussion and analysis relates to the financial condition and
results of operations of Burlington Northern Inc. (BNI) and its majority-owned
subsidiaries (collectively BN). The principal subsidiary is Burlington Northern
Railroad Company (Railroad).
 
CAPITAL RESOURCES AND LIQUIDITY
 
  Cash from operations and other resources
 
     Cash generated from operations is BN's principal source of liquidity and is
primarily used for dividends and capital expenditures. Operating activities
provided cash of $578 million in 1993, compared with $680 million in 1992 and
$368 million in 1991. The decrease in cash from operations in 1993 compared with
1992 was primarily attributable to an $81 million increase in labor-related
payments, a decline in the level of accounts receivables sold and a one-time
settlement agreement payment received in 1992. These items were partially offset
by a decrease in interest paid during 1993. The increase in cash from operations
in 1992 over 1991 was primarily due to increased profitability, a smaller
decline in the level of accounts receivable sold and the one-time settlement
agreement payment received in 1992. While operating cash flows for 1993 and 1991
were sufficient to fund dividends, such cash flows were not sufficient to
completely fund capital expenditures. In 1992, operating cash flows were
sufficient to fund both dividends and capital expenditures. Cash shortfalls as a
result of these cash outlays are generally financed with debt. Sources available
for such financing are discussed below.
 
     During the first quarter of 1993, BN entered into an agreement to acquire
350 new-technology alternating current traction motor locomotives. BN accepted
delivery of one locomotive during 1993 and anticipates delivery of between
approximately 60 and 100 each year from 1994 through 1997. Future cash from
operations during this strategic investment period may not, at times, be
sufficient to completely fund dividends as well as capital expenditures and
strategic investments. Therefore, these requirements will likely be financed
using a
 
                                       13
<PAGE>   16
 
combination of sources including, but not limited to, cash from operations,
operating leases, debt issuances and other miscellaneous sources. Each financing
decision will be based upon the most appropriate alternative available.
 
     During December 1993, BNI filed a registration statement with the
Securities and Exchange Commission for the issuance, from time to time, of up to
$500 million aggregate principal amount of debt securities. Net proceeds from
the sale of the debt securities, if any are offered and sold, will be used to
pay down debt or for other general corporate purposes.
 
     BNI acquired equipment which was financed in December 1993 through the
issuance of $78 million of 6.32 percent notes due 1994 to 2012.
 
     In July 1993, BNI issued $150 million of 7 1/2 percent senior unsecured
debentures due 2023 and used the proceeds for general corporate purposes,
including working capital. These debentures were the final borrowing under the
registration statement filed on September 24, 1991 covering the issuance, from
time to time, of up to $500 million aggregate principal amount of debt
securities.
 
     Railroad maintains an effective program for the issuance, from time to
time, of commercial paper. These borrowings are supported by Railroad's bank
credit agreement, thus outstanding commercial paper balances reduce available
borrowings under this agreement. The bank credit agreement allows borrowings of
up to $500 million on a short-term basis. The agreement is currently scheduled
to expire in November 1994. At Railroad's option, borrowing rates are based on
prime, certificate of deposit or London Interbank Offered rates. Annual facility
fees are 0.25 percent. The maturity value of commercial paper outstanding at
December 31, 1993 was $27 million, leaving a total of $473 million of the credit
agreement available, while no commercial paper was outstanding at December 31,
1992.
 
     Railroad has an agreement to sell, on a revolving basis, an undivided
percentage ownership interest in a designated pool of accounts receivable with
limited recourse. As of December 31, 1993, the agreement allowed for the sale of
accounts receivable up to a maximum of $175 million. The agreement expires not
later than December 1994. At December 31, 1993 and 1992, accounts receivable
were net of $100 million and $189 million, respectively, representing
receivables sold.
 
     In November 1992, BNI completed a public offering of 6,900,000 shares of
6 1/4 percent cumulative convertible preferred stock at $50 per share. Most of
the $337 million net proceeds from the offering were placed in trust to fund the
redemption of BNI's $300 million 9 5/8 percent notes due 1996. Under the terms
of the indenture, the 9 5/8 percent notes were redeemable at par, commencing
February 1, 1993. The notification for redemption of the 9 5/8 percent notes was
issued to holders of the notes in December 1992 with a redemption date of
February 1, 1993. The debt was considered to be extinguished as of December 31,
1992, because BNI had irrevocably placed assets in trust, prior to such date, to
be used solely to satisfy scheduled payments of both the interest on and
principal of the $300 million 9 5/8 percent notes. The difference between BNI's
redemption price and the net carrying value resulted in an immaterial loss which
was recorded in other income (expense), net in 1992.
 
     In July 1992, BNI issued $150 million of 7 percent senior unsecured notes
due 2002. The proceeds were used to retire $100 million of 14 3/4 percent notes
due August 15, 1992 and to reduce outstanding commercial paper balances. In
February 1992, BNI issued $200 million of 8 3/4 percent senior unsecured
debentures due 2022 and used the proceeds to reduce outstanding commercial paper
balances. These debt instruments provided favorable long-term interest rates and
matched long-term borrowing to the long-lived assets of BN's capital program.
 
     In November 1991, BNI completed a public offering of 10,350,000 shares of
common stock. The transaction resulted in net proceeds of $359 million which
were used primarily to retire $250 million of 11 5/8 percent subordinated
debentures.

</TABLE>
 
     Equipment expenditures for 1993 increased primarily as a result of
acquiring freight cars through purchases rather than through operating leases
and increased information system purchases. Capital roadway expenditures for
1993 increased compared with 1992 primarily due to spending related to the
severe flooding in the Midwest. Spending for signal and communication projects
and new strategic initiatives for transportation network management further
contributed to this increase. The average age of locomotives and freight cars at
year-end 1993 was 14.5 years and 18.6 years compared to 13.5 years and 18.4
years at year-end 1992.
 
     Capital roadway spending in 1992 reflects an increase in track programs in
the Powder River Basin to support BN's coal unit train service, as well as
additional signal and communication projects. Equipment expenditures were lower
in 1992 primarily due to the 1991 purchase of 50 high horsepower locomotives at
a cost of $76 million.
 
     BN projects capital spending for the next few years to be higher than in
previous years partially as a result of certain strategic investments, with a
projection for 1994 of approximately $650 million. As discussed in "Cash from
operations and other resources," BN has a commitment to acquire 350
new-technology alternating current traction motor locomotives through 1997.
Also, BN will continue its implementation of several strategic initiatives for
transportation network management using information systems technology.
 
     In addition to capital expenditures, BN continues to utilize operating
leases to fulfill certain equipment requirements. In 1994, BN anticipates
financing approximately $200 million of equipment through operating leases. The
method used to finance this equipment will depend upon current market conditions
and other factors. During 1993, BN renewed leases primarily for intermodal
doublestack cars and containers, and locomotives. In 1992, renewals were
primarily for covered hoppers, locomotives and coal cars.
 
  Dividends
 
     Common stock dividends declared have remained constant at $1.20 per common
share for 1993, 1992 and 1991. Dividends paid on common and preferred stock
during these periods were $125 million, $106 million and $92 million,
respectively. The increase in 1993 dividends was primarily attributable to the
issuance of 6,900,000 shares of 6 1/4 percent cumulative convertible preferred
stock in November 1992. The increase in 1992 was due in large part to the
issuance of 10,350,000 shares of common stock in November 1991. BNI expects to
continue its current policy of paying regular quarterly dividends on its common
and preferred stock, however, dividends are declared by the Board of Directors
based on profitability, capital expenditure requirements, debt service and other
factors.
 
  Capital structure
 
     BN's ratio of total debt to total capital, excluding redeemable preferred
stock, was 48 percent at the end of both 1993 and 1992 and 62 percent at the end
of 1991. In 1992, the total debt to total capital ratio improved from 1991
because debt was reduced, the 6 1/4 percent cumulative convertible preferred
stock was issued and net income exceeded dividend requirements.
 
RESULTS OF OPERATIONS
 
  Year ended December 31, 1993 compared with year ended December 31, 1992
 
     BN had net income of $296 million, or $3.06 per common share, on 89.7
million shares for 1993 compared with net income of $278 million, or $3.11 per
common share, on 88.6 million shares for 1992.

Results for 1993 included the effects of severe flooding in the Midwest, most
notably in the third quarter. The floods slowed and often halted operations,
forced extensive detours, increased car, locomotive and crew costs and resulted
in extensive rebuilding of damaged track and bridges. BN estimated that the
third quarter flooding reduced revenues during 1993 by $44 million and increased
operating expenses by $35 million, for a combined reduction of $79 million or
$.55 per common share. Net income for 1993 included the retroactive effects of
the Omnibus Budget Reconciliation Act of 1993 (the Act), which was passed into
law during August 1993. The Act increased the corporate federal income tax rate
by one percent, effective January 1, 1993, which reduced net income by $29
million, or $.32 per common share, through the date of enactment. BN recognized
a one-time, non-cash charge of $28 million to income tax expense to adjust
deferred taxes as of the enactment date and a charge of $1 million to current
income tax expense. Net income for 1992 included settlement payments received
for the reimbursement of attorneys' fees and costs incurred by BN in connection
with litigation filed by Energy Transportation Systems, Inc., and others, and
reimbursement of a portion of the amount paid by BN in settlement of that
action. The pre-tax amount recorded in other income (expense), net was
approximately $47 million. Also during 1992, BN's net income included a $21
million, or $.24 per common share, cumulative effect of changes in accounting
methods and a $17 million, or $.19 per common share, favorable tax settlement
with the Internal Revenue Service (IRS).
 
Revenues
 
     During 1993, BN refined Railroad's customer oriented business units by
creating smaller, more focused business units. The following table presents BN's

</TABLE>
 
     Coal revenues improved $12 million compared with 1992, primarily as a
result of increased traffic caused by a rise in the demand for electricity.
Higher revenues resulting from volume increases were partially offset by lower
yields arising from competitive pricing pressures in contract renegotiations,
traffic mix and other factors. Additionally, BN estimated lost coal revenues of
approximately $35 million for the third quarter of 1993 as a result of
flood-related problems in July and August which interrupted service to several
utilities.
 
     Agricultural Commodities revenues were $7 million higher than 1992 as
stronger yields were partially offset by lower volumes. Improved yields resulted
from a traffic mix with a greater portion of wheat traffic in 1993. Stronger
export demand, for high-quality wheat grown in regions served by BN, contributed
to a $74 million improvement in wheat revenues. Reduced crop quality and
production problems, stemming from poor planting and growing conditions,
resulted in lower corn volumes and produced a year-over-year decline in corn
revenues of $45 million.

     Intermodal revenues were $19 million higher in 1993 compared with 1992. BN
AMERICA (BNA) revenues in 1993 surpassed revenues in 1992 as a result of
continued escalating demand for containerized transportation and an increased
demand for intermodal service due generally to a shortage in truck capacity. As
import traffic expanded and shifted from ports in California to ports served by
BN in the Pacific Northwest, intermodal-international revenues increased.
Domestic trailer revenues declined as trailer traffic continued to convert to
containers, partially offsetting other Intermodal increases.
 
     Chemicals revenues for 1993 were $17 million greater than in 1992.
Increased plastics shipments for existing customers led improvements in overall
Chemicals revenues. Environmental logistics and fertilizer traffic in 1993
surpassed 1992 levels, also contributing to the higher revenues for Chemicals.
 
     Revenues for Minerals Processors increased $15 million compared with 1992.
As drilling activity increased, export traffic for clays and aggregates
expanded, contributing to greater revenues in 1993 than in 1992. Glass minerals
and cement revenues exceeded 1992 levels. This increase was due to expanded sand
traffic, which also benefited from increased drilling activity, and increased
cement traffic, related to certain highway and airport construction projects.
 
     Vehicles & Machinery revenues were $21 million greater than in 1992. This
improvement was due in part to growth in production and sales of light vehicles
which increased domestic traffic volumes. A rise in demand for heavy machinery
also contributed to greater revenues. Yields increased in 1993 primarily as a
result of a decline in the average length of haul.
 
     Forest Products, Iron & Steel and Aluminum, Non-Ferrous Metals & Ores had
lower revenues in 1993 compared with 1992. Current year Forest Products revenues
were $6 million less than in 1992 because of reduced lumber traffic, resulting
from a weak timber industry market, which was partially offset by increased
particle and construction board traffic. Iron & Steel revenues declined $6
million compared with 1992, primarily due to lower taconite traffic caused by
labor strikes at two large customers. Aluminum, Non-Ferrous Metals & Ores
revenues decreased by $5 million as aluminum production declined. Revenues for
Consumer Products were relatively flat compared with 1992.
 
Expenses
 
     Total operating expenses for 1993 were $4,038 million compared with $4,033
million for 1992. Despite the adverse effects of the Midwest flooding on
operating expenses during the third quarter of 1993, BN's year-to-date operating
ratio improved one percentage point, to 86 percent, compared with 87 percent for
1992.
 
     Overall compensation and benefits expenses for 1993 remained constant with
1992. Cost of living allowances (COLAs) for union employees were $24 million
lower during 1993 compared with 1992 due to timing differences of vesting
periods. Work force reductions and a decrease in railroad unemployment taxes
lowered expenses in 1993. These savings were offset by increases in incentive
compensation, wages and salaries, and higher costs for union health, welfare and
life insurance benefits. Increased wages were partially caused by a scheduled
three percent basic wage increase effective July 1993 and inefficiencies
associated with the Midwest flooding during 1993.
 
     Fuel expenses were $14 million higher during 1993 compared with 1992,
primarily due to weather-related reductions in fuel efficiency. Increased fuel
consumption due to higher traffic volume was substantially offset by the
decrease in the average price paid for diesel fuel, 61.5 cents per gallon in
1993 compared with 62.2 cents per gallon in 1992. Included in the 1993 average
price per gallon is a 4.3 cents per gallon increase in the federal fuel tax
effective October 1, 1993, as part of the Omnibus Budget Reconciliation Act of
1993. This increased tax added approximately $7 million to expense in the fourth
quarter.
 
     Materials expenses for 1993 increased $5 million compared with 1992. The
combination of flood-related problems and a larger fleet size increased
materials costs for locomotive repairs. Also, safety and protective equipment
expenditures were higher due to continued emphasis of BN's safety programs.
Offsetting these increases were lower car materials expenses.
 
                                       17
<PAGE>   20
 
     Equipment rents expenses were $6 million higher in 1993 compared with 1992
due to increases in both car-hire expenses and locomotive rentals. A reduction
in car-hire expenses during the first half of 1993, due to improved utilization
of equipment, was more than offset by flood-related inefficiencies which
increased car-hire expenses during the second half of 1993.
 
     Purchased services expenses for 1993 were $8 million higher than in 1992.
Contributing to this increase were cost increases for intermodal logistics,
training, moving and derailments. Lower trackage rights credits, which reduces
purchased services expenses, were received from the Southern Pacific
Transportation Company (SPTC) as the floods reduced SPTC volumes over BN track.
These increases were partially offset by decreases in contracted locomotive
repairs and consultant fees.
 
     Depreciation expense for 1993 was $14 million higher compared with 1992
primarily due to an increase in the asset base.
 
     The $42 million decrease in other operating expenses compared with 1992 was
primarily due to a $35 million decline in costs associated with personal injury
claims. BN has introduced a number of programs to improve worker safety and
counter increasing personal injury costs. Reductions in bad debt expense and
various other costs were partially offset by losses on property retired due to
flood damages and increased moving expenses.
 
     Interest expense declined $41 million in 1993 compared with 1992. This
decline was mainly due to a lower average long-term debt balance outstanding
during 1993 and the refinancing of higher interest rate debt throughout 1992.
 
     Other income (expense), net was $36 million lower in 1993 than in 1992. The
higher 1992 income was due to a first quarter net gain of $47 million for
payments and reimbursements received for the settlement of prior litigation.
This decline was partially offset by an increase in the net gain on property
dispositions in 1993 compared with 1992.
 
     The effective tax rate was 43.2 percent for 1993 compared with 33.8 percent
for 1992. This increase resulted primarily from the retroactive increase,
effective January 1, 1993, in tax rates as part of the Omnibus Budget
Reconciliation Act of 1993. Excluding the retroactive effect of the tax rate
change on deferred tax balances at January 1, 1993, BN's effective tax rate was
38.2 percent for 1993. Additionally, a favorable tax settlement with the IRS
reduced the 1992 effective tax rate by 3.8 percent.
 
  Year ended December 31, 1992 compared with year ended December 31, 1991
 
     BN had net income of $278 million, or $3.11 per common share, on 88.6
million shares for 1992 compared with a net loss of $320 million, or $4.14 per
common share, on 77.5 million shares for 1991. Results for 1992 were reduced by
$11 million, or $.13 per common share, net of tax, cumulative effect of an
accounting change in revenue recognition method and $10 million, or $.11 per
common share, net of tax, cumulative effect of an accounting change for
postretirement benefits. Results for 1991 included an after-tax special charge
of $442 million, or $5.79 per common share, related to railroad restructuring
costs and increases in liabilities for casualty and environmental clean-up
costs, and an extraordinary loss of $14 million, or $.18 per common share, net
of tax benefits, as a result of early retirement of debt.
 
     The 1991 special charge included the following pre-tax components (in
millions):

     Coal revenues in 1992 were $34 million below 1991. The decrease included
the effects of a two-day work stoppage during the second quarter. The effects of
the work stoppage were not recovered later in 1992 because of continued weak
demand. Mild weather during the first three quarters of 1992 decreased demand
for coal and slowed traffic compared with the prior year. In addition,
competitive pricing pressures in contract renegotiations and declining cost
indices, on which many coal contract rates are based, also contributed to lower
1992 revenues.
 
     Revenues for Agricultural Commodities were $1 million less in 1992 than in
1991. The decrease was primarily due to weak export demand for corn in the
latter three quarters of 1992 which contributed to a $36 million reduction
compared with 1991. This decrease was substantially offset by a $34 million
increase in wheat that resulted from strong export shipments during 1992.
 
     The $24 million increase in Intermodal revenues was driven by a $59 million
increase in BNA traffic that was attributable to increased demand for
containerized transportation. A portion of the increase in containerized
transportation was due to a conversion from trailer transportation which
decreased by $24 million compared with 1991.
 
     Forest Products revenues increased $20 million compared with 1991. The
increase reflects an improvement in lumber revenues that resulted from good
spring building conditions, favorable movements because of product pricing
pressures and increased demand caused by Hurricane Andrew's destruction.
Pulpmill feedstock revenues also increased because of higher demand for
woodchips. These increases were slightly offset by a decreased demand for paper
and paper products during 1992, partly due to excess supplies of newsprint.
 
     Revenues for Chemicals were $42 million greater in 1992 than in 1991. The
increase was primarily due to increased plastics shipments from new contracts.
Higher fertilizer and petroleum products revenues were also contributing
factors. Fertilizer traffic improved due to a strong spring application season
and increased shipments at the beginning of the year to replenish low inventory
levels from the fall of 1991. Petroleum products benefited from a stronger
economy in 1992 than in 1991.
 
     Revenues in 1992 for Consumer Products and Iron & Steel both improved by $8
million compared with 1991. The improvement for Consumer Products resulted from
higher bulk food products revenues, due largely from an increased movement of
sugar, and higher frozen foods revenues. Frozen foods revenues improved over
 
                                       19
<PAGE>   22
 
the prior year due largely to increased french fry traffic resulting from
favorable product prices. Iron & Steel revenues improved due to increased
traffic because of two new pipe projects.
 
     Revenues for Minerals Processors, Vehicles & Machinery and Aluminum,
Non-Ferrous Metals & Ores were relatively flat in 1992 compared with 1991. While
Vehicles & Machinery revenues were flat overall, automotive revenues increased
as higher traffic volume more than offset lower yields. Declining yields reflect
the rates used in late 1991 and 1992 long-term contract renewals, which were
influenced by competitive pricing pressures. This increase in automotive
revenues was offset by declines in heavy machinery and government traffic
revenues. The slight decrease in Minerals Processors revenues was attributable
to a weaker demand for glass minerals and cement products related to the
construction and automobile industries. Aluminum, Non-Ferrous Metals & Ores
benefited from a stronger economy in 1992 than in 1991.
 
Expenses
 
     Total operating expenses for 1992 were $4,033 million compared with
expenses of $4,090 million, excluding a $708 million special charge, in 1991.
The operating ratio for 1992 was 87 percent compared with the 1991 ratio,
excluding the special charge, of 90 percent. The improvement in operating
expenses was primarily attributable to savings in compensation and benefits and
fuel costs.
 
     Compensation and benefits expenses decreased by $47 million compared with
1991. During 1991, BN recorded a $77 million accrual for union employees'
signing bonuses and for COLAs. The 1992 COLA accruals were $58 million.
Current-year savings of $22 million were also noted in health, welfare and life
insurance benefits due to union contract modifications. Smaller crew sizes and a
full year of reduced pay rates for employees on reserve boards, which were
established in the second half of 1991, also contributed to lower wages and
salaries in 1992. These combined savings were somewhat offset by increases in
mechanical, maintenance crew and other wages. Also, increasing use of the wage
continuation program for injured employees, which was phased in during 1991,
served to further offset the savings.
 
     Fuel expenses were $20 million lower than in 1991. In 1992, BN paid 62.2
cents per gallon compared with 65.5 cents in 1991. This lower average fuel price
per gallon resulted in approximately $19 million of the overall savings. Reduced
consumption also contributed slightly to the overall decrease.
 
     Materials expenses for 1992 were $12 million higher than in 1991. Materials
costs were higher due to increased locomotive repairs during 1992. Increasing
track repair cost and related work equipment repair cost also contributed to the
overall increase.
 
     The $12 million decrease in equipment rents expenses compared with 1991 was
largely due to a decline in locomotive related expenses. Locomotive cost savings
resulted from a renegotiated purchased power agreement and the expiration,
during 1992, of several locomotive leases which were not renewed. These cost
savings were somewhat offset by an increase in car-hire expenses due to lower
1992 than 1991 recoveries for prior period car-hire overpayments, which offset
car-hire expenses in the period recovered.
 
     Purchased services expenses increased $7 million in 1992 compared with
1991. The increases over 1991 were a result of higher expenses related to
computer programming costs associated with the implementation of several
strategic initiatives, the expansion of a BNA customer service center due to
increased BNA traffic, payments for car repairs and intermodal logistics costs.
These increases were somewhat offset by lower environmental clean-up expenses,
decreased relocation costs, fewer locomotive overhauls and increased payments
from SPTC for trackage rights.
 
     Depreciation expense for 1992 was $9 million lower than in 1991. The
decrease was primarily attributable to reduced depreciation for rail subsequent
to the current-year implementation of an Interstate Commerce Commission required
service life study for rail. The effect of the study on rail depreciation was to
reduce 1992 expense by $28 million. This decrease was partially offset by
increased depreciation, due to a larger asset base.
 
     Other expenses for 1992 was $12 million greater than in 1991. Although
reported injury claims decreased, personal injury expense, excluding wage
continuation costs discussed in compensation and benefits, increased by
approximately $18 million as settlement costs for claims settled increased, and
hearing loss claims
 
                                       20
<PAGE>   23
 
continued to develop. Bad debt accruals also contributed to this increase. Lower
derailment expenses and a decline in moving expenses partially offset this
increase.
 
     Interest expense decreased $40 million in 1992 compared with 1991. Lower
market interest rates and reduced commercial paper balances were significant
contributors to this decrease. The reduction of long-term debt and the
refinancing of high interest rate debt, during 1992 and late 1991, added to the
current-year savings. Also, 1991 interest expense included an interest accrual
related to a rate litigation case.
 
     In 1992, BN recorded other income, net of expense, of $41 million versus
other expense, net of income, of $25 million in 1991. The 1992 income is due
primarily to a first quarter net gain of $47 million for payments and
reimbursements received for the settlement of prior litigation. Loss on
investment and loss on sale of receivables were also lower in 1992 than in 1991.
 
     The effective tax rate was 33.8 percent and 37.6 percent in 1992 and 1991,
respectively. The lower 1992 rate was the result of a fourth quarter Appeals
Division settlement of IRS audits for the years 1981 through 1985. The total tax
benefit recorded in 1992 was $17 million which reduced the effective tax rate by
3.8 percent.
 
OTHER MATTERS
 
     In October 1991, Railroad entered into an agreement (Crew Consist Agreement
No. 1) with the United Transportation Union (UTU) covering the southern portion
of Railroad's system. Crew Consist Agreement No. 1 provided for crews on most
through-freight trains to consist of one conductor and one engineer and for
crews on all other trains to consist of one brakeman, one conductor and one
engineer.
 
     Under the terms of Crew Consist Agreement No. 1, Railroad offered the
opportunity for voluntary separation from employment in return for severance
payments of up to $60,000 per employee. Remaining conductors or brakemen who, as
a result of Crew Consist Agreement No. 1, were unable to hold a position in
active service, due to relative seniority, were placed on a reserve board.
Employees in reserve status received compensation at a rate equal to either 75
percent of their previous 12-month earnings, or 75 percent of the basic five-day
yard helper rate of pay, whichever is greater, and are required to be available
for return to active service on 15 days' notice. Each UTU member on the southern
portion of Railroad's system received a lump-sum payment of $1,000 upon
ratification of Crew Consist Agreement No. 1.
 
     In May 1993, Railroad entered into an agreement (Crew Consist Agreement No.
2) with the UTU covering approximately 3,400 UTU members in the northern portion
of Railroad's system. Crew Consist Agreement No. 2 provides for crews on most
through-freight trains to consist of one conductor and one engineer and for
crews on all other trains to consist of one brakeman, one conductor and one
engineer. It is similar to Crew Consist Agreement No. 1, covering the southern
portion of Railroad's system. Each UTU member on the northern portion of
Railroad's system received a one-time lump-sum payment of $5,000, pursuant to
Crew Consist Agreement No. 2.
 
     Under the terms of Crew Consist Agreement No. 2, Railroad offered the
opportunity for voluntary separation from employment in return for severance
payments of up to $80,000 per employee. Conductors and brakemen who choose not
to accept the voluntary separation offer can elect volunteer surplus status
pursuant to which they will receive $60,000 to be paid out over a period of 18
to 48 months, as each selects. If such employee has not been recalled to active
service by the time such payments cease upon expiration of the selected period,
such employee will remain in volunteer surplus status, without further
compensation or benefits, until recalled to active service. Employees in
volunteer surplus status may be called back to service only after the
individuals in reserve status, within their own subdivided seniority district,
have been recalled. Remaining conductors and brakemen who, as a result of Crew
Consist Agreement No. 2, are not needed in train service, and who do not elect
one of the above severance options, will be placed on a reserve board.
 
     Employees in reserve status will receive compensation equal to either 75
percent of their previous 12-month earnings, or 75 percent of the basic five-day
yard helper rate of pay, whichever is greater, and are required to be available
for return to active service on 15 days' notice.
 
                                       21
<PAGE>   24
 
     In October 1993, the UTU elected to adopt Crew Consist Agreement No. 2 for
those southern portion UTU members who were previously covered by Crew Consist
Agreement No. 1. Crew Consist Agreement No. 2 was implemented on the southern
portion of the Railroad's system during the fourth quarter of 1993. Upon
implementation, each of the approximately 3,300 UTU members on the southern
portion of Railroad's system received a one-time lump-sum payment of $4,000,
which was the incremental difference between the $1,000 lump-sum payment
received following ratification of Crew Consist Agreement No. 1 and the amount
received by UTU members following adoption of Crew Consist Agreement No. 2.
 
     Railroad will continue to remove excess positions from train service
through the implementation of Crew Consist Agreement No. 2. Approximately 1,350
excess positions have been removed as a result of employees accepting severance
or voluntary surplus payments. Other excess positions have been eliminated and
personnel formerly in those positions have been assigned to reserve boards,
absorbed through additional train starts and/or utilized in quality and safety
initiatives. Based upon its experience under Crew Consist Agreement No. 1,
Railroad anticipates that the number of employees on reserve status will decline
over time.
 
     In July 1993, the American Train Dispatchers Association ratified an April
agreement which will facilitate the consolidation of all dispatching functions
into a centralized train dispatching office in Fort Worth, Texas by the end of
1995.
 
     Since 1935, BN has participated in the national railroad retirement system
which is separate from the national social security system. Under this system,
an independent Railroad Retirement Board administers the determination and
payment of benefits to all railroad workers. Both BN and its employees are
subject to a tax on employee earnings which is above the normal social security
rate assessed to those who are employed outside the railroad industry.
 
     Personal injury claims, including work-related injuries to employees, are a
significant expense for the railroad industry. Employees of BN are compensated
for work-related injuries according to the provisions of the Federal Employers'
Liability Act (FELA). FELA's system of requiring finding of fault, coupled with
unscheduled awards and reliance on the jury system, has resulted in significant
increases in expense. The result has been a trend during the last several years
of significant increases in BN's personal injury expense which reflects the
combined effects of increasing medical expenses, legal judgments and
settlements. To improve worker safety and counter increasing costs, BN has
introduced a number of programs to reduce the number of personal injury claims
and the dollar amount of claims settlements which helped reduce cost in 1993. If
these efforts continue to be successful, future expenses could be further
reduced. The total amount of personal injury expenses (including wage
continuation payments) were $216 million, $253 million and $224 million in 1993,
1992 and 1991, respectively. BN is also working with others through the
Association of American Railroads to seek changes in legislation to provide a
more equitable program for injury compensation in the railroad industry.
 
     BN's operations, as well as those of its competitors, are subject to
extensive federal, state and local environmental regulation. In order to comply
with such regulation and to be consistent with BN's corporate environmental
policy, BN's operating procedures include practices to protect the environment.
Amounts expended relating to such practices are inextricably contained in the
normal day-to-day costs of BN's business operations.
 
     Under the requirements of the Federal Comprehensive Environmental Response,
Compensation and Liability Act of 1980 (Superfund) and certain other laws, BN is
potentially liable for the cost of clean-up of various contaminated sites
identified by the U.S. Environmental Protection Agency and other agencies. BN
has been notified that it is a potentially responsible party (PRP) for study and
clean-up costs at a number of sites and, in many instances, is one of several
PRPs. BN generally participates in the clean-up of these sites through
cost-sharing agreements with terms that vary from site to site. Costs are
typically allocated based on relative volumetric contribution of material, the
amount of time the site was owned or operated, and/or the portion of the total
site owned or operated by each PRP. However, under Superfund and certain other
laws, as a PRP, BN can be held jointly and severally liable for all
environmental costs associated with a site.
 
                                       22
<PAGE>   25
 
     Environmental costs include initial site surveys and environmental studies
of potentially contaminated sites as well as costs for remediation and
restoration of sites determined to be contaminated. Liabilities for
environmental clean-up costs are initially recorded when BN's liability for
environmental clean-up is both probable and a reasonable estimate of associated
costs can be made. Adjustments to initial estimates are recorded as necessary
based upon additional information developed in subsequent periods. BN conducts
an ongoing environmental contingency analysis, which considers a combination of
factors, including independent consulting reports, site visits, legal reviews,
analysis of the likelihood of participation in and ability to pay for clean-up
by other PRPs, and historical trend analysis.
 
     BN is involved in a number of administrative and judicial proceedings in
which it is being asked to participate in the clean-up of sites contaminated by
material discharged into the environment. BN paid $27 million, $20 million and
$21 million during 1993, 1992 and 1991, respectively, relating to mandatory
clean-up efforts, including amounts expended under federal and state voluntary
clean-up programs. At this time, BN expects to spend approximately $120 million
in future years to remediate and restore these sites.
 
     Liabilities for environmental costs represent BN's best estimates for
remediation and restoration of these sites and include asserted and unasserted
claims. BN's best estimate of unasserted claims was approximately $5 million as
of the end of 1993. Although recorded liabilities include BN's best estimates of
all costs, without reduction for anticipated recovery from insurance, BN's total
clean-up costs at these sites cannot be predicted with certainty due to various
factors such as the extent of corrective actions that may be required, evolving
environmental laws and regulations, advances in environmental technology, the
extent of other PRPs participation in clean-up efforts, developments in ongoing
environmental analyses related to sites determined to be contaminated, and
developments in environmental surveys and studies of potentially contaminated
sites. As a result, charges to income for environmental liabilities could
possibly have a significant effect on results of operations in a particular
quarter or fiscal year as individual site studies and remediation and
restoration efforts proceed or as new sites arise. However, expenditures
associated with such liabilities are typically paid out over a long period, in
some cases up to 40 years, and are therefore not expected to have a material
adverse effect on BN's consolidated financial position, cash flow or liquidity.
 
     In November 1992, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 112, "Employers'
Accounting for Postemployment Benefits." This standard requires employers to
recognize benefits provided to former or inactive employees after employment but
before retirement, if certain conditions are met. In the first quarter of 1994,
BN will adopt SFAS No. 112. The principal effect of adopting this standard will
be to establish liabilities for long-term and short-term disability plans. The
effect upon earnings to adopt this standard is expected to be approximately $15
to $20 million. The initial effect of applying this standard will be reported as
the effect of a change in accounting method and previously issued financial
statements will not be restated.
 
     In May 1993, the FASB issued SFAS No. 115, "Accounting for Certain
Investments in Debt and Equity Securities." SFAS No. 115 addresses the
accounting and reporting requirements for investments in equity securities that
have readily determinable fair values and for all investments in debt
securities, and is effective for fiscal years beginning after December 15, 1993.
The initial effect of applying this standard is to be reported as the effect of
a change in accounting method and previously issued financial statements may not
be restated. No material effect on BN's financial condition or results of
operations is anticipated from the adoption of SFAS No. 115.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
BURLINGTON NORTHERN INC. AND SUBSIDIARIES
 
1. ACCOUNTING POLICIES
 
  Principles of consolidation
 
     The consolidated financial statements include the accounts of Burlington
Northern Inc. (BNI) and its majority-owned subsidiaries (collectively BN). The
principal subsidiary is Burlington Northern Railroad Company (Railroad). All
significant intercompany accounts and transactions have been eliminated.
 
  Property and equipment
 
     Main line track is depreciated on a group basis using a units-of-production
method. All other property and equipment are depreciated on a straight-line
basis over estimated useful lives. Interstate Commerce Commission (ICC)
regulations require periodic formal studies of ultimate service lives for all
railroad assets. Resulting service life estimates are subject to review and
approval by the ICC. An annual review of rates and accumulated depreciation is
performed and appropriate adjustments are recorded. Significant premature
retirements are recorded as gains or losses at the time of their occurrence,
which would include major casualty losses, abandonments, sales and obsolescence
of assets. Expenditures which significantly increase asset values or extend
useful lives are capitalized. Repair and maintenance expenditures are charged to
operating expense when the work is performed. All properties are stated at cost.
 
  Materials and supplies
 
     Materials and supplies consist mainly of diesel fuel, repair parts for
equipment and other railroad property and are valued at average cost.
 
  Revenue recognition
 
     Transportation revenues are recognized proportionately as a shipment moves
from origin to destination.
 
  Income taxes
 
     Income taxes are provided based on earnings reported for tax return
purposes in addition to a provision for deferred income taxes. The provision for
income taxes includes deferred taxes determined by the change in the deferred
tax liability, which is computed based on the differences between the financial
statement and tax basis of assets and liabilities as measured by applying
enacted tax laws and rates. Deferred tax expense is the result of changes in the
net liability for deferred taxes. Investment tax credits were accounted for
under the "flow-through" method.
 
  Earnings (loss) per common share
 
     Earnings (loss) per common share are determined by dividing net income,
after deduction of preferred stock dividends, by the weighted average number of
common shares outstanding and common share equivalents. Common share equivalents
were not included in the computation of the loss per common share in 1991 since
their effect would have been antidilutive.
 
  Cash and cash equivalents
 
     All short-term investments which mature in less than 90 days when purchased
are considered cash equivalents for purposes of disclosure in the consolidated
balance sheets and consolidated statements of cash flows. Cash equivalents are
stated at cost, which approximates market value.
 
  Reclassifications
 
     Certain prior year data has been reclassified to conform to the current
year presentation. These reclassifications had no effect on previously reported
net income, stockholders' equity or cash flows.

2. ACCOUNTS RECEIVABLE, NET
 
     Railroad has an agreement to sell, on a revolving basis, an undivided
percentage ownership interest in a designated pool of accounts receivable with
limited recourse. As of December 31, 1993, the agreement allowed for the sale of
accounts receivable up to a maximum of $175 million. The agreement expires not
later than December 1994. Average monthly proceeds from the sale of accounts
receivable were $182 million, $190 million and $269 million in 1993, 1992 and
1991, respectively. At December 31, 1993 and 1992, accounts receivable were net
of $100 million and $189 million, respectively, representing receivables sold.
Included in other income (expense), net were expenses of $9 million, $11 million
and $20 million in 1993, 1992 and 1991, respectively, relating to the sale. BN
maintains an allowance for doubtful accounts based upon the expected
collectibility of all trade accounts receivable, including receivables sold with
recourse. Allowances for doubtful accounts and recourse on receivables sold of
$17 million and $16 million have been recorded at December 31, 1993 and 1992.

</TABLE>
 
     Certain noncancellable leases were classified as capital leases and were
included in property and equipment. The consolidated balance sheets at December
31, 1993 and 1992 included $36 million and $35 million, respectively, of
property and equipment under capital leases. The related depreciation was
included in depreciation expense. Accumulated depreciation for property and
equipment under capital leases was $31 million and $29 million at December 31,
1993 and 1992, respectively.
 
     Main line track is depreciated on a group basis using a units-of-production
method. The accumulated depreciation and annual depreciation accrual rates for
railroad assets other than main line track are calculated using a straight-line
method and statistical group measurement techniques, which closely approximate
unit depreciation. The group techniques project depreciation expense and
estimated accumulated depreciation utilizing historical experience and expected
future conditions relating to the timing of asset retirements, cost of removal,
salvage proceeds, maintenance practices and technological changes. In this
manner, the net book value of reported assets reflects estimated remaining asset
utility on a historical cost basis.
 
     Due to the imprecision of annual reviews using statistical group
measurement techniques for long-term asset retirement, replacement and
deterioration patterns, BN adjusts accumulated depreciation for significant
differences between recorded accumulated depreciation and computed requirements.
Differences between recorded accumulated depreciation and computed requirements
are recognized prospectively on a straight-line basis. Under ICC regulations, BN
conducts service life studies on an annual basis. Results of service life
studies are recorded over the remaining life of the asset group studied. During
1993, BN completed service life studies of equipment and road property. During
1992, the service life studies consisted of rail. The effect of implementing the
results of new service life studies and similar rate adjustments were to
decrease depreciation expense in 1993 by $2 million compared with 1992 and to
decrease depreciation expense in 1992 by $28 million compared with 1991. In
future periods, service life studies will be conducted on other asset groups as
well as these same assets under ICC requirements. However, the impact of such
studies is not determinable at this time.
 
     In 1993, capitalization of certain software development costs increased as
a result of new strategic initiatives. Capitalization of software development
costs begins upon establishment of technological feasibility.
 
                                       29
<PAGE>   32
 
The establishment of technological feasibility is based upon completion of
planning, design and other technical performance requirements.
 
     Capitalized software development costs are amortized over a seven-year
estimated useful life using the straight-line method. No amortization was
recorded for the year ended December 31, 1993. Unamortized capitalized software
costs were $6 million as of December 31, 1993.

     Railroad maintains an effective program for the issuance, from time to
time, of commercial paper. These borrowings are supported by Railroad's bank
credit agreement, thus outstanding commercial paper balances reduce available
borrowings under this agreement. The bank credit agreement allows borrowings of
up to $500 million on a short-term basis. The agreement is currently scheduled
to expire in November 1994. At Railroad's option, borrowing rates are based on
prime, certificate of deposit or London Interbank Offered rates. Annual facility
fees are 0.25 percent. The maturity value of commercial paper outstanding at
December 31, 1993 was $27 million, leaving a total of $473 million of the credit
agreement available, while no commercial paper was outstanding at December 31,
1992.
 
     The financial covenants of the bank credit agreement require that
Railroad's consolidated tangible net worth, as defined in the agreement, be at
least $1.4 billion, and its debt, as defined in the agreement, cannot exceed the
lesser of 140 percent of its consolidated tangible net worth or $2.5 billion.
 
     The agreement contains an event of default arising out of the occurrence
and continuance of a "Change in Control." A "Change in Control" is generally
defined as the acquisition of more than 50 percent of the voting securities of
BNI, which has not been approved by the BNI Board of Directors, a change in the
control

relationship between BNI and Railroad, and finally, a "Change in Control" is
deemed to occur when a majority of the seats on the BNI Board of Directors is
occupied by persons who are neither nominated by BNI management nor appointed by
directors so nominated.
 
     The commercial paper program is further summarized as follows (dollars in
millions):

     Maturities of commercial paper averaged 4 and 14 days in 1993 and 1992,
respectively.
 
     During December 1993, BNI filed a registration statement with the
Securities and Exchange Commission for the issuance, from time to time, of up to
$500 million aggregate principal amount of debt securities. Net proceeds from
the sale of the debt securities, if any are offered and sold, will be used to
pay down debt or for other general corporate purposes.
 
     BNI acquired equipment which was financed in December 1993 through the
issuance of $78 million of 6.32 percent notes due 1994 to 2012.
 
     In July 1993, BNI issued $150 million of 7 1/2 percent senior unsecured
debentures due 2023 and used the proceeds for general corporate purposes,
including working capital. These debentures were the final borrowing under the
registration statement filed on September 24, 1991 covering the issuance, from
time to time, of up to $500 million aggregate principal amount of debt
securities.
 
     In November 1992, BNI completed a public offering of 6,900,000 shares of
6 1/4 percent cumulative convertible preferred stock at $50 per share. Most of
the $337 million net proceeds from the offering were placed in trust to fund the
redemption of BNI's $300 million 9 5/8 percent notes due 1996. Under the terms
of the indenture, the 9 5/8 percent notes were redeemable at par, commencing
February 1, 1993. The notification for redemption of the 9 5/8 percent notes was
issued to holders of the notes in December 1992 with a redemption date of
February 1, 1993. The debt was considered to be extinguished as of December 31,
1992, because BNI had irrevocably placed assets in trust, prior to such date, to
be used solely to satisfy scheduled payments of both the interest on and
principal of the $300 million 9 5/8 percent notes. The difference between BNI's
redemption price and the net carrying value resulted in an immaterial loss which
was recorded in other income (expense), net in 1992.
 
     In July 1992, BNI issued $150 million of 7 percent senior unsecured notes
due 2002. The proceeds were used to retire $100 million of 14 3/4 percent notes
due August 15, 1992 and to reduce outstanding commercial paper balances. In
February 1992, BNI issued $200 million of 8 3/4 percent senior unsecured
debentures due 2022 and used the proceeds to reduce outstanding commercial paper
balances.
 
     Aggregate long-term debt scheduled maturities for 1994 through 1998 and
thereafter are $185 million, $31 million, $25 million, $248 million, $24 million
and $1,266 million, respectively.
 
     Substantially all Railroad properties and certain other assets are pledged
as collateral to or are otherwise restricted under the various Railroad
long-term debt agreements.
 
5. DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The estimated fair values of BN's financial instruments at December 31,
1993 and 1992 and the methods and assumptions used to estimate the fair value of
each class of financial instruments held by BN, were as follows:
 
                                       31
<PAGE>   34
 
  Cash and short-term investments
 
     The carrying amount approximated fair value because of the short maturity
of these instruments.
 
  Notes receivable
 
     The fair value of notes receivable was estimated by discounting the
anticipated cash flows. Discount rates of 8.7 percent and 10 percent at December
31, 1993 and 1992, were determined to be appropriate when considering current
U.S. Treasury rates and the credit risk associated with these notes.
 
  Accrued interest payable
 
     The carrying amount approximated fair value as the majority of interest
payments are made semiannually.
 
  Long-term debt and commercial paper
 
     The fair value of BN's long-term debt, excluding unamortized discount, was
primarily based on secondary market indicators. For those issues not actively
quoted, estimates were based on each obligation's characteristics. Among the
factors considered were the maturity, interest rate, credit rating, collateral,
amortization schedule, liquidity and option features such as optional redemption
or optional sinking funds. These features were compared to other similar
outstanding obligations to determine an appropriate increment or spread, above
U.S. Treasury rates, at which the cash flows were discounted to determine the
fair value. The carrying amount of commercial paper approximated fair value
because of the short maturity of these instruments.
 
  Redeemable preferred stock
 
     The fair value of BN's redeemable preferred stock represented the market
value as shown on the New York Stock Exchange at December 31, 1992.
 
  Recourse liability from sale of receivables
 
     It is unlikely that BN would be able to pay a second entity to assume its
recourse obligation. Therefore, the carrying value of the allowance for doubtful
accounts on receivables sold approximated the fair value of the recourse
liability related to those receivables.
 
     The carrying amount and estimated fair values of BN's financial instruments
were as follows (in millions):

     BN also holds investments in, and has advances to, several unconsolidated
transportation affiliates. It was not practicable to estimate the fair value of
these financial instruments, which were carried at their original cost of $19
million and $22 million in the December 31, 1993 and 1992 consolidated balance
sheets. There were no quoted market prices available for the shares held in the
affiliated entities, and the cost of obtaining an independent valuation would
have been excessive considering the materiality of these investments to BN.
 
     In addition, BN has a note receivable, from a shortline railroad, that has

1993 and 1992. As it is not practicable to forecast the traffic volume over the
remaining life of the note, it was not included in the notes receivable amount
shown above.
 
     In May 1993, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 115, "Accounting for
Certain Investments in Debt and Equity Securities." SFAS No. 115 addresses the
accounting and reporting requirements for investments in equity securities that
have readily determinable fair values and for all investments in debt
securities, and is effective for fiscal years beginning after December 15, 1993.
The initial effect of applying this standard is to be reported as the effect of
a change in accounting method and previously issued financial statements may not
be restated. No material effect on BN's financial condition or results of
operations is anticipated from the adoption of SFAS No. 115.
 
6. INCOME TAXES
 
     Effective January 1, 1993, BN adopted SFAS No. 109, "Accounting for Income
Taxes." SFAS No. 109 modifies SFAS No. 96, which established the liability
method of accounting for income taxes, and had been adopted by BN effective
January 1, 1986. BN adopted SFAS No. 109 consistent with the transitional
guidelines of SFAS No. 109. The effect of the adoption was to increase the
current portion of the deferred income tax asset with a corresponding increase
in the noncurrent deferred income tax liability of $26 million at January 1,
1993. There was no effect on net income, stockholders' equity or cash flows.
 
     Income tax expense (benefit), excluding the effect of the extraordinary
item and the cumulative effect of changes in accounting methods, was as follows
(in millions):

     As of December 31, 1993, approximately $5 million of alternative minimum
tax credit carryovers with no expiration date are available to offset future tax
liabilities. The alternative minimum tax credits have been fully recognized for
financial accounting purposes. In 1993, tax benefits of $4 million related to
the adjustment to recognize a minimum pension liability were allocated directly
to stockholders' equity.
 
     On August 10, 1993, the Omnibus Budget Reconciliation Act of 1993 (the Act)
was signed into law. The Act increased the corporate federal income tax rate by
one percent, effective January 1, 1993, which reduced net income by $29 million,
or $.32 per common share, through the date of enactment. A one-time, non-cash
charge of $28 million to income tax expense was recorded as an adjustment to
deferred taxes as of the enactment date and a charge of $1 million to income tax
expense was recorded as an adjustment to current income taxes.
 
     In December 1992, BN received notification that an Appeals Division
settlement of the Internal Revenue Service audits for the years 1981 through
1985 had been approved by the Joint Committee on Taxation. This action settled
all unagreed issues for those years. The tax effect of the settlement was
included in the 1992 tax provision as shown below (in millions, except per share

8. PREFERRED CAPITAL STOCK
 
  No Par Value Preferred Stock, authorized 25,000,000 shares -- 6,900,000 shares
issued
 
     In November 1992, BNI issued 6,900,000 shares of 6 1/4 percent Cumulative
Convertible Preferred Stock, Series A No Par Value. The convertible preferred
stock is not redeemable prior to December 26, 1995. Thereafter, the shares may
be redeemed at BNI's option, in whole or in part, during the twelve months
beginning November 24 of each year except for 1995 which commences December 26,
at the following redemption prices per share: $52.1875 in 1995, $51.875 in 1996,
$51.5625 in 1997, $51.25 in 1998, $50.9375 in 1999, $50.625 in 2000, $50.3125 in
2001, and $50 in 2002 and thereafter. The convertible preferred stock may be
converted, at the option of the holder at any time, into the number of shares of
BNI's common stock equal to the liquidation preference of each share of
convertible preferred stock, $50, divided by the conversion price of $47 per
share of common stock. The convertible preferred stockholders have no voting
rights unless six quarterly dividend payments are in default. In a default, such
stockholders may vote separately as a class with all other series of the No Par
Value Preferred Stock to elect two additional directors. Voting rights will
continue until all arrearages have been paid. As of December 31, 1993, there had
been no such defaults.
 
  Class A Preferred Stock Without Par Value, authorized 50,000,000
shares -- unissued
 
     At December 31, 1993, BNI had available for issuance 50,000,000 shares of
Class A Preferred Stock Without Par Value. The Board of Directors has the
authority to issue such stock in one or more series, to fix the number of shares
and to fix the designations and the powers. On July 10, 1986, the Board of
Directors designated a series of 800,000 shares of Class A Preferred Stock
Without Par Value as Series A Junior Participating Class A Preferred Stock. On
December 19, 1991, the Board of Directors increased the Series A Junior
Participating Class A Preferred Stock designation to 3,000,000 shares. Each one
one-hundredth of a share will have dividend and voting rights approximately
equal to those of one share of common stock of BNI. In addition, on July 10,
1986, the Board of Directors declared a dividend distribution of one right for
each outstanding share of common stock of BNI. The rights become exercisable if,
without BNI's prior consent, a person or group acquires securities having 20
percent or more of the voting power of all of BNI's voting securities or
announces a tender offer which would result in such ownership. Each right, when
exercisable, entitles the registered holder to purchase from BNI one
one-hundredth of a share of Series A Junior Participating Class A Preferred
Stock at a price of $190 per one one-hundredth of a share, subject to
adjustment. If, after the rights become exercisable, BNI were to be acquired
through a merger, each right would permit the holder to purchase, for the
exercise price, stock of the acquiring company having a value of twice the
exercise price. In addition, if any person acquires 25 percent or more of BNI
(other than as a result of a cash offer for all shares), each right not owned by
the holder of such 25 percent would permit the purchase, for the exercise price,
of stock of BNI having a value of twice the exercise price. The rights may be
redeemed by BNI under certain circumstances until their expiration date for $.05
per right.

9. COMMON STOCK AND ADDITIONAL PAID-IN CAPITAL
 
     BNI is authorized to issue 300,000,000 shares of Common Stock Without Par
Value. At December 31, 1993, there were 88,796,139 shares of common stock
outstanding. Each holder of common stock is entitled to one vote per share in
the election of directors and on all matters submitted to a vote of
stockholders. Subject to the rights and preferences of the convertible preferred
stock and any future issuance of additional preferred stock, each share of
common stock is entitled to receive dividends as may be declared by the Board of
Directors out of funds legally available and to share ratably in all assets
available for distribution to stockholders upon dissolution or liquidation. No
holder of common stock has any preemptive right to subscribe for any securities
of BNI.
 
     Effective December 1991, the Board of Directors of BNI authorized the
transfer, to additional paid-in capital, of $1,343 million representing capital
in excess of the stated value of common stock.
 
10. STOCK OPTIONS AND OTHER CAPITAL STOCK
 
  Stock options
 
     Under BN's stock option plans, options may be granted to officers and key
salaried employees at fair market value on the date of grant. All options expire
within ten years after the date of grant. BN may also grant stock appreciation
rights (SARs) in tandem with stock options which would be exercisable during the
same period as the options. SARs entitle an option holder to receive a payment
equal to the difference between the option price and the fair market value of
the common stock at the date of exercise of the SAR. To the extent the SAR is
exercised, the related option is cancelled and to the extent the option is
exercised the related SAR is cancelled. Any change in the current market value
over the SARs exercise price would be recognized at such time as an adjustment
to compensation expense. During the third quarter of 1991, following a change in
rules 16(a) and 16(b) promulgated under the Securities and Exchange Act of 1934,
as amended, substantially all holders of SARs relinquished those rights. As a
result, there were no further adjustments to compensation expense in times of
changing market prices after the year ended December 31, 1991. Adjustments to
compensation expense during the year ended December 31, 1991 were not
significant.
 
     Activity in stock option plans was as follows:

  Other capital stock
 
     BN has restricted stock award plans under which up to 1,700,000 common
shares may be awarded to eligible employees and directors of BN. No cash payment
is required by the individual. Shares awarded under the plan may not be sold,
transferred or used as collateral by the holder until the shares awarded become
free of the restrictions, generally by one-thirds on the third, fourth and fifth
anniversaries of the date of grant. All shares still subject to restrictions are
generally forfeited and returned to the plan if the employee or director's
relationship with BN is terminated. If the employee or director retires, becomes
disabled or dies, the restrictions will lapse at that time. The compensation
expense resulting from the award of restricted stock is valued at the average of
the high and low market prices of BNI common stock on the date of the award,
recorded as a reduction of stockholders' equity, and charged to expense evenly
over the service period. Restricted stock awards under these plans, net of
forfeitures, were 232,354, 214,475 and 223,850 shares in 1993, 1992 and 1991,
respectively. A total of 870,525, 824,877 and 757,565 restricted common shares
were outstanding at December 31, 1993, 1992 and 1991, respectively. Compensation
expense was not significantly affected for all periods presented.
 
     BN also has a stock award plan which provides for grants of shares of BNI's
common stock to full-time employees, excluding officers, based upon performance.
A total of 100,000 shares of common stock has been authorized for these awards.
The shares awarded contain no restrictions and the recipients have full
shareholder rights and privileges. Compensation expense is based upon the
average of the high and low market prices of BNI common stock on the date of
grant. During the years ended December 31, 1993, 1992 and 1991, 5,540, 11,720
and 7,790 shares were awarded under this plan. The related compensation expense
was not significant.
 
     An employee stock purchase plan was adopted in 1992 effective in 1993 as a
means to encourage employee ownership of BNI common stock. A total of 500,000
shares of common stock were authorized for distribution under this plan. The
plan allows eligible BN employees to use the proceeds of incentive compensation
awards to purchase shares of BNI common stock at a discount, as determined by
the BNI Board of Directors, from the market price and may require that the
shares purchased be held for a specific time period as also determined by the
Board of Directors. The difference between the market price and the employees'
purchase price is recorded as additional compensation expense. During the year
ended December 31, 1993, 34,629 shares were awarded under this plan. The related
compensation expense was not significant.
 
11. RETIREMENT PLANS
 
     BN has non-contributory defined benefit pension plans covering
substantially all non-union employees. The benefits are based on years of
credited service and the highest five-year average compensation levels.
Contributions to the plans are based upon the projected unit credit actuarial
funding method and are limited to
 
                                       37
<PAGE>   40
 
amounts that are currently deductible for tax purposes. Contributions are
intended to provide not only for benefits attributed to service to date but also
for those expected to be earned in the future.

the consolidated balance sheets were as follows (in millions):

</TABLE>
 
     Net pension cost for 1993 was lower than 1992 primarily due to a decrease
in the rate of future compensation growth from 6 percent to 5.5 percent. The
changes in pension cost for the two years ended December 31, 1992 were primarily
attributable to the expected year-to-year changes in the discount rates.
 
     The discount rate and rate of increase in future compensation levels used
in determining the actuarial present value of the benefit obligations were 7
percent and 5.5 percent at December 31, 1993 and 8.5 percent and 5.5 percent at
December 31, 1992. The expected long-term rate of return on assets was 9.5
percent for 1993 and 10 percent for the other years presented.
 
     BN sponsors a 401(k) thrift and profit sharing plan which covers
substantially all non-union employees. BN matches 35 percent of the first 6
percent of the employees' contributions, which is subject to certain percentage
limits of the employees' earnings, at the end of each quarter. Depending on BN's
performance, an additional matching contribution of 20 to 40 percent can be made
at the end of the year. BN's expense was $6 million, $4 million and $6 million
in 1993, 1992 and 1991, respectively. Effective January 1, 1994, BN also
sponsors a 401(k) retirement savings plan covering substantially all union
employees which is non-contributory on the part of BN.
 
12. OTHER BENEFIT PLANS
 
  Postretirement benefits
 
     Effective January 1, 1992, BN adopted SFAS No. 106, "Employers' Accounting
for Postretirement Benefits Other Than Pensions." BN provides certain
postretirement health care benefits, payable until age 65, for a small number of
retirees who retired on or before March 1986.
 
                                       38
<PAGE>   41
 
     Both the accumulated postretirement benefits obligation and cost associated
with this plan were insignificant. Life insurance benefits are provided for
eligible non-union employees. BN adopted accrual accounting for the expense of
these plans in 1992 by taking a $16 million cumulative effect charge to income
in order to establish a liability for those benefits. BN pays benefits as claims
are processed.

postretirement benefit cost reflected in the consolidated balance sheets (in

</TABLE>
 
     The discount rate used in determining the benefit obligation was 7 percent
at December 31, 1993 and 8.5 percent at December 31, 1992. The health care cost
trend rate is assumed to decrease gradually from 15 percent in 1994 to 6 percent
in 2003 and thereafter. Increasing the assumed health care cost trend rate by
one percentage point in each year would have an insignificant effect on the
accumulated postretirement benefit obligation at December 31, 1993 and 1992 as
well as the aggregate of the service and interest cost components in 1993 and
1992.
 
     Under collective bargaining agreements, Railroad participates in
multi-employer benefit plans which provide certain postretirement health care
and life insurance benefits for eligible union employees. Insurance premiums
attributable to retirees, which are expensed as incurred, were $10 million in
1993 and $11 million in both 1992 and 1991.
 
  Postemployment benefits
 
     In November 1992, the FASB issued SFAS No. 112, "Employers' Accounting for
Postemployment Benefits." This standard requires employers to recognize benefits
provided to former or inactive employees after employment but before retirement,
if certain conditions are met. In the first quarter of 1994, BN will adopt SFAS
No. 112. The principal effect of adopting this standard will be to establish
liabilities for long-term and short-term disability plans. The effect upon
earnings to adopt this standard is expected to be approximately $15 to $20
million. The initial effect of applying this standard will be reported as the
effect of a change in accounting method and previously issued financial
statements will not be restated.
 
13. CASUALTY AND ENVIRONMENTAL RESERVES
 
     Casualty reserves consist primarily of personal injury claims, including
work-related injuries to employees. Employees of BN are compensated for
work-related injuries according to the provisions of the Federal Employers'
Liability Act. Liabilities for personal injury claims are estimated through an
actuarial model that considers historical data and trends and is designed to
record those costs in the period of occurrence. BN conducts an ongoing review
and analysis of claims and other information to ensure the continued adequacy of
casualty reserves. To the extent costs exceed recorded accruals they will not
materially affect BN's financial condition, results of operations or liquidity.
 
                                       39
<PAGE>   42
 
     Under the requirements of the Federal Comprehensive Environmental Response,
Compensation and Liability Act of 1980 (Superfund) and certain other laws, BN is
potentially liable for the cost of clean-up of various contaminated sites
identified by the U.S. Environmental Protection Agency and other agencies. BN
has been notified that it is a potentially responsible party (PRP) for study and
clean-up costs at a number of sites and, in many instances, is one of several
PRPs. BN generally participates in the clean-up of these sites through
cost-sharing agreements with terms that vary from site to site. Costs are
typically allocated based on relative volumetric contribution of material, the
amount of time the site was owned or operated, and/or the portion of the total
site owned or operated by each PRP. However, under Superfund and certain other
laws, as a PRP, BN can be held jointly and severally liable for all
environmental costs associated with a site.
 
     Environmental costs include initial site surveys and environmental studies
of potentially contaminated sites as well as costs for remediation and
restoration of sites determined to be contaminated. Liabilities for
environmental clean-up costs are initially recorded when BN's liability for
environmental clean-up is both probable and a reasonable estimate of associated
costs can be made. Adjustments to initial estimates are recorded as necessary
based upon additional information developed in subsequent periods. BN conducts
an ongoing environmental contingency analysis, which considers a combination of
factors, including independent consulting reports, site visits, legal reviews,
analysis of the likelihood of participation in and ability to pay for clean-up
by other PRPs, and historical trend analysis.
 
     Liabilities for environmental costs represent BN's best estimates for
remediation and restoration of these sites and include asserted and unasserted
claims. BN's best estimate of unasserted claims was approximately $5 million as
of the end of 1993. Although recorded liabilities include BN's best estimates of
all costs, without reduction for anticipated recovery from insurance, BN's total
clean-up cost at these sites cannot be predicted with certainty due to various
factors such as the extent of corrective actions that may be required, evolving
environmental laws and regulations, advances in environmental technology, the
extent of other PRPs participation in clean-up efforts, developments in ongoing
environmental analyses related to sites determined to be contaminated, and
developments in environmental surveys and studies of potentially contaminated
sites. As a result, charges to income for environmental liabilities could
possibly have a significant effect on results of operations in a particular
quarter or fiscal year as individual site studies and remediation and
restoration efforts proceed or as new sites arise. However, expenditures
associated with such liabilities are typically paid out over a long period, in
some cases up to 40 years, and are therefore not expected to have a material
adverse effect on BN's consolidated financial position, cash flow or liquidity.
 
14. COMMITMENTS AND CONTINGENCIES
 
  Lease commitments
 
     BN has substantial lease commitments for railroad, highway and data
processing equipment, office buildings and a taconite dock facility. Most of
these leases provide the option to purchase the equipment at fair market value
at the end of the lease. However, some provide fixed purchase price options.
 
     Lease rental expense for operating leases was $175 million, $189 million
and $195 million for the years ended December 31, 1993, 1992 and 1991,
respectively.

     In addition to the above, BN also receives and pays rents for railroad
equipment on a per diem basis, which is included in equipment rents.
 
  Other commitments and contingencies
 
     During 1993, BN entered into an agreement to acquire 350 new-technology
alternating current traction motor locomotives. BN accepted delivery of one
locomotive in 1993 and anticipates delivery of between approximately 60 and 100
each year from 1994 through 1997.
 
     BN has two locomotive electrical power purchase agreements, expiring in
1998 and 2001, that currently involve 199 locomotives. Payments required by the
agreements are based upon the number of megawatt hours of energy consumed,
subject to specified take-or-pay minimums. The rates specified in the two
agreements are renegotiable every two years. BN's 1994 minimum commitment
obligation is $48 million. Based on projected locomotive power requirements,
BN's payments in 1994 are expected to be in excess of the minimum. Payments
under the agreements totaled $53 million, $56 million and $55 million in 1993,
1992 and 1991, respectively, which exceeded the applicable minimums in each
year. In 1990, BN entered into a letter of credit for the benefit of a vendor.
This letter of credit is a performance guarantee for up to $15 million in major
overhauls to be performed on the power purchase equipment.
 
     In connection with its program to transfer certain rail lines to
independent operators, BN has agreed to make certain payments for services
performed by the operators in connection with traffic that involves the
shortlines and Railroad as carriers. These payments are not fixed in amount,
will vary with such factors as traffic volumes and shortline costs and are not
expected to exceed normal business requirements for services received. These
payments are reflected as reductions to revenue to conform with reporting to the
ICC. Revenues for these joint moves, including amounts applicable to the
independent operator portion of the line haul, are reflected by BN as revenue
from operations.
 
     There are no other commitments or contingent liabilities which BN believes
would have a material adverse effect on the consolidated financial position,
results of operations or liquidity.

     In the first quarter of 1992, BN entered into a settlement agreement
relating to the reimbursement of attorneys' fees and costs incurred by BN in
connection with litigation filed by Energy Transportation Systems, Inc., and
others, and reimbursement of a portion of the amount paid in prior years by BN
in settlement of that action. Under the terms of the settlement, BN received
approximately $50 million before legal fees.
 
16. ACCOUNTING CHANGES
 
     Effective January 1, 1993, BN adopted SFAS No. 109, "Accounting for Income
Taxes." SFAS No. 109 modifies SFAS No. 96, which established the liability
method of accounting for income taxes, and had been adopted by BN effective
January 1, 1986. BN adopted SFAS No. 109 consistent with the transitional
guidelines of SFAS No. 109. The effect of the adoption was to increase the
current portion of the deferred income tax asset with a corresponding increase
in the noncurrent deferred income tax liability of $26 million at January 1,
1993. There was no effect on net income, stockholders' equity or cash flows.
 
     In January 1992, the Emerging Issues Task Force of the FASB reached a
consensus that origination of service revenue recognition was not an acceptable
method beginning in 1992 for the freight services industry. Accordingly,
effective January 1, 1992, BN changed its method of revenue recognition from one
which recognized transportation revenue at the origination point, to a method
whereby transportation revenue is recognized proportionately as a shipment moves
from origin to destination. The cumulative effect, net of a $7 million income
tax benefit, of the change on the prior year's revenue, at the time of adoption,
decreased 1992 net income by $11 million, or $.13 per common share.
 
     In the fourth quarter of 1992, effective January 1, 1992, BN adopted SFAS
No. 106, "Employers' Accounting for Postretirement Benefits Other Than
Pensions," and elected immediate recognition of the $16 million transition
obligation. The cumulative effect, net of a $6 million income tax benefit, of
the change on prior years', at the time of adoption, decreased 1992 net income
by $10 million, or $.11 per common share.
 
     Financial results for the first quarter of 1992 have previously been
restated for the cumulative effect of the change in accounting method for
revenue recognition, which had previously been reported in other income
(expense), net and for the cumulative effect of the implementation of the
accounting standard for postretirement benefits. There was no material effect on
the second and third quarter, and those quarters were not restated for the
adoption of SFAS No. 106.
 
17. 1991 SPECIAL CHARGE
 
     Included in 1991 results was a pre-tax special charge of $708 million
related to railroad restructuring costs and increases in liabilities for
casualty claims and environmental clean-up costs. The 1991 special charge
included the following components:
 
  Restructuring
 
     This program provided for work force reduction of employees. The
restructuring program and related charge had two components:
 
        - $185 million to provide for employee related costs for the elimination
          of surplus crew positions.
 
                                       42
<PAGE>   45
 
        - $40 million to provide for employee related costs for a separation
          program.
 
  Other
 
        - $350 million to increase casualty reserves based on an actuarial
          valuation and escalations in both the cost and number of projected
          hearing loss claims.
 
        - $133 million to increase environmental reserves based on studies and
          analyses of potential environmental clean-up and restoration costs.
 
     The special charge reduced 1991 net income by $442 million, or $5.79 per
common share.
 
18. EXTRAORDINARY ITEM
 
     The extraordinary loss for 1991 of $14 million, $.18 per common share,
resulted from the loss on redemption of 11 5/8 percent debentures, net of an $8
million income tax benefit. The 1991 redemption of the 11 5/8 percent debentures
was completed using proceeds from the issuance of common stock.

REPORT OF MANAGEMENT
 
To the Stockholders and Board of Directors of
Burlington Northern Inc. and Subsidiaries
 
     The accompanying consolidated financial statements have been prepared by
management in conformity with generally accepted accounting principles. The
fairness and integrity of these financial statements, including any judgments
and estimates, are the responsibility of management, as is all other information
presented in this Annual Report on Form 10-K.
 
     In the opinion of management, the financial statements are fairly stated,
and, to that end, BN maintains a system of internal control which: provides
reasonable assurance that transactions are recorded properly for the preparation
of financial statements; safeguards assets against loss or unauthorized use;
maintains accountability for assets; and requires proper authorization and
accounting for all transactions. Management is responsible for the effectiveness
of internal controls. This is accomplished through accounting and other control
systems, policies and procedures, employee selection and training, appropriate
delegation of authority and segregation of responsibilities, and an established
code of ethics for employees. To further ensure compliance with established
standards and related control procedures, BN conducts a substantial corporate
audit program.
 
     Our independent accountants provide an objective independent review through
their audit of BN's financial statements. Their audit includes a review of
internal accounting controls to the extent deemed necessary for the purposes of
their audit.
 
     The Audit Committee of the Board of Directors, composed solely of outside
directors, meets regularly with the independent accountants, management and
corporate audit to review the work of each and to ensure that each is properly
discharging its financial reporting and internal control responsibilities. To
ensure complete independence, the independent accountants and the corporate
audit department have full and free access to the Audit Committee to discuss the
results of their audits, the adequacy of internal accounting controls and the
quality of financial reporting.

REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Stockholders and Board of Directors of
Burlington Northern Inc. and Subsidiaries
 
     We have audited the consolidated financial statements and financial
statement schedules of Burlington Northern Inc. and Subsidiaries listed in Item
14 of this Form 10-K. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements and financial statement
schedules based on our audits.
 
     We conducted our audits according to generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Burlington Northern Inc. and Subsidiaries as of December 31, 1993 and 1992, and
the consolidated results of their operations and their cash flows for each of
the three years in the period ended December 31, 1993 in conformity with
generally accepted accounting principles. In addition, in our opinion, the
financial statement schedules referred to above, when considered in relation to
the basic financial statements taken as a whole, present fairly, in all material
respects, the information required to be included therein.
 
     As discussed in Note 16 to the consolidated financial statements, the
Company changed its method of accounting for income taxes in 1993 and for
revenue recognition and postretirement benefits other than pensions in 1992.

- ---------------
 
(1) Results for the third quarter of 1993 include the effects of the Omnibus
    Budget Reconciliation Act of 1993 (the Act) which was signed into law on
    August 10, 1993. The Act increased the corporate federal income tax rate by
    one percent, effective January 1, 1993, which reduced net income by $29
    million, or $.32 per common share, through the date of enactment. Results
    for the third quarter of 1993 also include the effects of the severe
    flooding in the Midwest. BN estimates the flooding reduced revenues and
    operating income during the quarter by $44 million and $79 million,
    respectively, and reduced net income by $49 million, or $.55 per common
    share.
 
(2) Amounts may not total to the annual earnings per share because each quarter
    and the year are calculated separately based on average outstanding shares
    and common share equivalents during that period.
 
(3) The higher of average or end of period market price is used to determine
    common share equivalents for fully diluted earnings per share. In addition,
    the if-converted method is used for convertible preferred stock when
    computing fully diluted earnings per common share.
 
(4) Results for 1992 reflect the cumulative effect of the change in accounting
    method for revenue recognition, and the cumulative effect of the
    implementation of the accounting standard for postretirement benefits
    (Statement of Financial Accounting Standards No. 106). The cumulative
    effect of the change in accounting method for revenue recognition decreased
    1992 net income by $11 million, or $.13 per common share. The cumulative
    effect of the change in accounting method for postretirement benefits
 
    
                                      46
<PAGE>   49
 
     decreased 1992 net income by $10 million, or $.11 per common share, and had
     no immediate effect on cash flows.
 
(5) Results for the fourth quarter of 1992 include a $17 million reduction in
     income tax expense as a result of a favorable Internal Revenue Service
     settlement which allowed BN to recognize additional depreciation deductions
     for income taxes.

the $10 Par Value Preferred Stock are first issued, and shall be paid to
holders of record on such respective dates which, with respect to the initial
quarterly dividend payment date, shall not be earlier than the date on which
shares of such series are first issued and, with respect to subsequent
quarterly dividend payment dates, shall not exceed 50 days preceding such
dividend payment dates, as may be determined by the Board of Directors in
advance of the payment of the particular dividend.

         3. The corporation may at any time redeem the whole or from time to
time any part of the $10 Par Value Preferred Stock at the par value thereof
plus an amount equal to all dividends, if any, accrued thereon to the date
designated for redemption with respect to each share so to be redeemed, and in
addition thereto (except with respect to shares redeemed for purposes of the
Sinking Funds referred to in paragraph 5 of this Section I) a premium per share
payable upon redemption, over and above the par value thereof and any accrued
dividends thereon, of $0.20 from the date of issue thereof to and including
March 1, 1983; $0.10 from March 2, 1983 to and including March 1, 1985; and
such shares shall be redeemable without premium thereafter.

         4. In the event of any liquidation, dissolution or winding up of the
corporation, before any payment or distribution of the assets of the
corporation (whether capital or surplus) shall be made to or set apart for the
holders of any class or classes of stock of the corporation ranking junior to
the $10 Par Value Preferred Stock upon liquidation, the holders of the shares
of the $10 Par Value Preferred Stock shall be entitled to receive a payment at
the rate of $10 per share, plus an amount equal to all
<PAGE>   2
dividends (whether or not earned or declared) accrued thereon to the date of
final distribution to such holders: provided, however, that upon any voluntary
liquidation, dissolution or winding up of the corporation (including any
liquidation, dissolution or winding up of the corporation resulting from
government seizure by right of eminent domain), the holders of shares of $10
Par Value Preferred Stock shall be entitled to receive at the time thereof,
over and above the par value thereof and any accrued dividends thereon, a
premium equal to the then applicable optional redemption premium fixed in
paragraph 3 of this Section 1.

         5. (i) During each calendar year, as and for a Mandatory Sinking Fund
the corporation shall retire through redemption in such year in the manner
hereinafter provided or through the cancellation of shares purchased in such
year at or below $10 per share (plus accrued dividends) 123,458 shares of $10
Par Value Preferred Stock; provided, however, that said redemptions and
purchases may be made only out of the net assets of the corporation legally
available therefor remaining after full cumulative dividends upon all shares of
the $10 Par Value Preferred Stock then outstanding to the end of the last
preceding dividend period shall have been paid, or declared and a sum
sufficient for the payment thereof set apart for payment. Subject to the
provisions of subparagraph (iv) of this paragraph 5, the number of shares of
$10 Par Value Preferred Stock required to be retired in each year as and for
the Mandatory Sinking Fund shall be subject to reduction by the application of
credits in respect of the Optional Sinking Fund as provided in subparagraph
(ii) of this paragraph 5 and in respect of shares previously purchased as
provided in subparagraph (iii) of this paragraph 5.

         (ii) During each calendar year, out of such net assets, as and for an
Optional Sinking Fund the corporation may retire through redemption a number of
shares up to but not more than 123,458 shares of $10 Par Value Preferred Stock,
and retirements as and for the Optional Sinking Fund may be credited against
the number of shares required to be retired as and for the Mandatory Sinking
Fund for any subsequent year or years selected by the Board of Directors in its
discretion, subject to the provisions of subparagraph (iv) of this paragraph 5;
provided, however, that no $10 Par Value Preferred Stock may be retired as and
for the Optional Sinking Fund when there exists any deficiency in the Mandatory
Sinking Fund. The right to retire $10 Par Value Preferred Stock as and for the
Optional Sinking Fund is noncumulative and to the extent not exercised in any
year shall terminate.

         (iii) There shall be allowed to the corporation as a further credit
against the number of shares to be retired as and for the Mandatory Sinking
Fund for any year or years selected by the Board of Directors in its
discretion, subject to the provisions of subparagraph (iv) of this paragraph 5,
shares of $10 Par Value Preferred Stock which the corporation has at any time
theretofore purchased at or below $10 per share (plus accrued dividends) and
cancelled and which have not theretofore been used for the purpose of any such
credit.

         (iv) The credits against the Mandatory Sinking Fund provided for by
subparagraphs (ii) and (iii) of this paragraph 5 may not be applied to reduce
the Mandatory Sinking Fund for a particular year when the effect of such
application would be to relieve the corporation for more than two consecutive
calendar years from the requirement of retiring in such year in the manner
specified in the first sentence of subparagraph (i) of this paragraph 5 the
number of shares required to be retired annually, prior to the application of
said credits, as and for the Mandatory Sinking Fund.

         (v) The Mandatory Sinking Fund shall be cumulative, so that if in any
calendar year the corporation shall not retire the number of shares required to
be retired as and for the Mandatory Sinking Fund after the application of said
credits, the obligation to retire such shares shall continue.

         (vi) Shares of $10 Par Value Preferred Stock shall be redeemed for the
Mandatory or Optional Sinking Fund at the redemption price of $10 per share,
plus an amount equal to the dividends accrued thereon to the redemption date.

                                     -2-

Mandatory or Optional Sinking Fund shall be selected, and notice of redemption
shall be given, as provided in paragraph 2 of Section III of this Article, and
the corporation shall pay on such redemption from its general funds an amount
equal to the accrued dividends on the shares so called for redemption.

         6.  Shares of $10 Par Value Preferred Stock redeemed, purchased or
otherwise acquired by the corporation (whether for the Sinking Funds or
otherwise) may not be reissued.

         7. If at any time the corporation shall have failed to pay dividends
in full on the $10 Par Value Preferred Stock, thereafter and until dividends in
full, including all dividends on the $10 Par Value Preferred Stock outstanding
accrued to the last preceding quarterly dividend payment date, shall have been
declared and set apart for payment or paid, (a) the corporation without the
affirmative vote or consent of the holders of at least 66 2/3% of all the $10
Par Value Preferred Stock at the time outstanding, given in person or by proxy,
either in writing or by resolution adopted at a special meeting called for the
purpose, shall not redeem less than all of the $10 Par Value Preferred Stock at
such time outstanding and (b) neither the corporation nor any subsidiary shall
purchase any $10 Par Value Preferred Stock except in accordance with a purchase
offer made in writing to all holders of $10 Par Value Preferred Stock upon such
terms as the Board of Directors in their sole discretion shall determine (which
determination shall be final and conclusive) to be fair and equitable;
provided, however, that nothing shall prevent the corporation from completing
the redemption of shares of $10 Par Value Preferred Stock as and for the
Mandatory or Optional Sinking Fund, the notice of redemption of which was
mailed prior to such failure.

         8. Except when otherwise herein or by the laws of the State of
Delaware specifically provided, the holders of the $10 Par Value Preferred
Stock shall not be entitled to vote on any question or in any proceedings or to
be represented at or to receive notice of any meeting of stockholders of the
corporation; provided, however, that whenever dividends payable on the $10 Par
Value Preferred Stock shall be in default in an aggregate amount equivalent to
six full quarterly dividends, the holders of the $10 Par Value Preferred Stock
shall have the exclusive and special right, voting as a single class separately
from the holders of any other class of stock of the corporation, to elect at
the next annual meeting of the stockholders of the corporation two directors of
the corporation and the remaining directors shall be elected by the other class
or classes of stock entitled to vote therefor. Such right of election shall
continue until such time as all dividends accumulated on the $10 Par Value
Preferred Stock shall have been paid in full, or declared and set apart for
payment, at which time such right of election shall terminate, subject to
revesting in the event of each and every subsequent default in an aggregate
amount equivalent to six full quarterly dividends. In the exercise of the
special voting rights provided in this paragraph 8, the holders of the $10 Par
Value Preferred Stock shall have one vote per share.  Nothing herein contained
shall in any way restrict the power of the Board of Directors to increase or
decrease the number of directors in accordance with the laws of the State
of Delaware and the By-Laws of the corporation.

         9. At any annual meeting of stockholders at which the holders of the
$10 Par Value Preferred Stock shall have the right of election provided in
paragraph 8 of this Section I, the presence, in person or by proxy, of the
holders of a majority of the $10 Par Value Preferred Stock shall be required to
constitute a quorum of the $10 Par Value Preferred Stock for the election of
any director by the holders of the $10 Par Value Preferred Stock. At any such
meeting or adjournment thereof, (a) the absence of a quorum of the $10 Par
Value Preferred Stock shall not prevent the election of the directors to be
elected by the other class or classes of stock entitled to vote therefor, and
the absence of a quorum of such other class or classes of stock shall not
prevent the election of the directors to be elected by the $10 Par Value
Preferred Stock, and (b) in the absence of either or both such quorums, a
majority of the holders present in person or by proxy of the stock or stocks
which lack a quorum shall have the power to adjourn the meeting for the
election of directors which they are entitled to elect, from time to time,
without notice other than announcement at the meeting, until a quorum shall be
present.




                                     -3-
<PAGE>   4
         10. The directors elected by the holders of the $10 Par Value
Preferred Stock in exercise of the right of election provided in paragraph 8 of
this Section I shall continue in office until their successors shall have been
elected by such holders or until termination of such right of election. The
vacancies in the Board of Directors so occurring upon the termination of such
right of election shall be filled by the majority vote of the remaining
directors. Any vacancies in the Board of Directors occurring during any period
when the holders of the $10 Par Value Preferred Stock have such right of
election shall be filled only by vote of a majority (even if that be only a
single director) of the remaining directors theretofore elected by the holders
of the class or classes of stock which elected the director whose office shall
have become vacant.

         11. So long as any $10 Par Value Preferred Stock is outstanding, the
corporation will not:

                 (a) declare, or pay, or set apart for payment, any dividends
         (other than dividends payable in shares of stock of the corporation
         ranking junior to the $10 Par Value Preferred Stock, both as to
         dividends and upon liquidation) or make any distribution, on any class
         or classes of stock of the corporation ranking junior to the $10 Par
         Value Preferred Stock either as to dividends or upon liquidation, and
         will not redeem, purchase or otherwise acquire, whether voluntarily,
         for a mandatory or optional sinking or retirement fund or otherwise,
         or permit any subsidiary to purchase or otherwise acquire, any shares
         of any such junior class if at the time of making such declaration,
         payment, distribution, redemption, purchase or acquisition the
         corporation shall be in default with respect to any dividend payable
         on the $10 Par Value Preferred Stock or any obligation to redeem
         shares of the $10 Par Value Preferred Stock pursuant to any mandatory
         sinking or retirement fund; provided, however, that the corporation
         may at any time redeem, purchase or otherwise acquire shares of any
         such junior class in exchange for, or out of the net cash proceeds
         from the substantially concurrent sale of, shares of any class of
         stock of the corporation ranking junior to the $10 Par Value Preferred
         Stock both as to dividends and upon liquidation;

                 (b) without the affirmative vote or consent of the holders of
         at least 66 2/3% of all the $10 Par Value Preferred Stock at the time
         outstanding, voting together as a single class separately from the
         holders of any other class of stock of the corporation, given in
         person or by proxy, either in writing or by resolution adopted at a
         special meeting called for the purpose, (i) create any other class or
         classes of stock ranking prior to the $10 Par Value Preferred Stock,
         either as to dividends or upon liquidation, or increase the authorized
         number of shares of any such other class of stock or (ii) amend, alter
         or repeal any of the provisions of this Article so as to adversely
         affect the preferences, special rights or powers of the $10 Par Value
         Preferred Stock; provided, however, that no vote or consent of the $10
         Par Value Preferred Stock shall be required for increasing the
         authorized amount of the $10 Par Value Preferred Stock or for the
         creation of one or more classes of preferred stock so long as such
         class or classes do not rank prior to the $10 Par Value Preferred
         Stock, either as to dividends or upon liquidation; and

                 (c) without the affirmative vote or consent of the holders of
         at least a majority of all the $10 Par Value Preferred Stock at the
         time outstanding, voting as a single class separately from the holders
         of any other class of stock of the corporation, given in person or by
         proxy, either in writing or by resolution adopted at a special
         meeting called for the purpose, voluntarily dissolve, liquidate or
         wind up.

         2. The holders of the $9 Preferred Stock shall be entitled to receive
fully cumulative dividends, when and as declared by the Board of Directors of
the corporation out of funds legally available therefor, at the rate of $9.00
per share, and no more, per annum. Such dividends shall be payable quarterly on
the first day of each March, June, September and December, commencing on the
first of such dates after shares of the $9 Preferred Stock are first issued,

to subsequent quarterly dividend payment dates, shall not exceed 50 days
preceding such dividend payment dates, as may be determined by the Board of
Directors in advance of the payment of the particular dividend.

                          1988                            None                 
</TABLE>                       

provided, however, that prior to March 1, 1984 the corporation shall not redeem
any of the $9 Preferred Stock at its option, directly or indirectly, from the
proceeds of or in anticipation of any refunding operation involving the
incurring of debt or the issuance of preferred stock ranking equal or prior to
the $9 Preferred Stock in respect of dividends or preference on liquidation and
having a cost to the corporation, computed in accordance with generally
accepted financial practice, of less than 9% per annum.

         4. In the event of any liquidation, dissolution or winding up of the
corporation, before any payment or distribution of the assets of the
corporation (whether capital or surplus) shall be made to or set apart for the
holders of any shares of stock of the corporation ranking junior to the $9
Preferred Stock upon liquidation, the holders of the $9 Preferred Stock shall
be entitled to receive a payment at the rate of $100 per share plus an amount
equal to all dividends accrued thereon to the date of final distribution to
such holders; provided, however, that upon any voluntary liquidation,
dissolution or winding up of the corporation (including any liquidation,
dissolution or winding up of the corporation resulting from government seizure
by right of eminent domain), the holders of the $9 Preferred Stock shall be
entitled to receive at the time thereof, over and above the amount of $100 per
share and any accrued dividends thereon, a premium per share equal to the then
applicable optional redemption premium fixed in paragraph 3 of this Part A.

         5. (a) On March 1 in each year, commencing in 1985, the corporation
shall retire through redemption 102,000 shares of $9 Preferred Stock (such
number and redemption price to be adjusted appropriately in the event of any
stock split, issuance of additional shares of such series pursuant to paragraph
8 of this Part A, combination or any other recapitalization and such number, so
adjusted if appropriate, to be reduced by a percentage obtained by dividing
such number of shares of $9 Preferred Stock, if any, which the corporation has,
at any time prior to the record date for




                                     -5-

redemption, acquired by purchase or redemption or otherwise retired except
pursuant to paragraph 3 of this Part A or this paragraph 5 by 510,000 (or
510,000 as adjusted pursuant to the first clause in this parenthetical)) at a
redemption price of $100 per share plus an amount equal to all dividends, if
any, accrued thereon to the date designated for redemption; provided, however,
that such redemptions may be made only out of the net assets of the corporation
legally available therefor remaining after full cumulative dividends upon all
of the shares of $9 Preferred Stock and upon any other shares of equal rank
therewith as to dividends then outstanding to the end of the last preceding
dividend period shall have been paid or declared and a sum sufficient for the
payment thereof set apart for payment.

         (b) The obligation of the corporation to retire shares of $9 Preferred
Stock pursuant to subparagraph (a) of this paragraph 5 shall be cumulative so
that, if in any calendar year the corporation shall not retire the number of
shares of such series so required to be retired, the obligation to retire such
shares shall continue and funds legally available therefor shall be applied for
such purpose until such obligation is discharged.

         6. Notwithstanding the provisions of paragraph 2(a) of Section III of
this Article, if less than all of the $9 Preferred Stock then outstanding is to
be redeemed pursuant to paragraphs 3 or 5 of this Part A, the corporation shall
prorate, as nearly as practical, the shares to be redeemed among all registered
holders of shares of such series in proportion to the respective number of
shares of such series held by each such holder.

         7. If at any time the corporation shall have failed to pay, or declare
and set apart for payment, dividends accrued on the $9 Preferred Stock to the
last preceding quarterly dividend payment date, or shall have failed to redeem,
or to set aside funds necessary for the redemption of, the number of shares
required to be redeemed pursuant to subparagraph (a) of paragraph 5 of this
Part A, thereafter and until such dividends shall have been paid, or sums
sufficient for the payment thereof shall have been set apart for payment, or
until such shares shall have been redeemed, or funds necessary for the
redemption thereof shall have been set aside, as the case may be, (i) the
corporation shall not exercise any optional right to redeem any Preferred Stock
of any other class or series or less than all of the $9 Preferred Stock at the
time outstanding and (ii) neither the corporation nor any subsidiary shall
purchase any Preferred Stock except in accordance with a purchase offer made in
writing to all holders of Preferred Stock of all classes and series upon such
terms as the Board of Directors, in its sole discretion after consideration of
the respective annual dividend rates and other relative rights and preferences
of the respective classes and series, shall determine will result in fair and
equitable treatment among the respective classes and series. Nothing in this
paragraph 7 shall prevent the corporation from completing the redemption of any
Preferred Stock of any class or series, notice of the redemption of which was
mailed prior to any failure to pay dividends on or redeem shares of the $9
Preferred Stock.

         8. So long as any of the $9 Preferred Stock is outstanding, the
corporation will not, without the affirmative vote or consent, in addition to
any other vote or consent required hereby or by the laws of the State of
Delaware, of the holders of at least a majority of the shares of such series at
the time outstanding, voting as a single class separate from the holders of any
class or series of stock of the corporation, given in person or by proxy,
either in writing or by resolution adopted at a special meeting called for the
purpose, increase the authorized number of shares of $9 Preferred Stock to more
than 510,000 or increase the aggregate amount payable pursuant to paragraph 4
of this Part A upon any involuntary liquidation, dissolution or winding up of
the corporation to more than $51,000,000 plus accrued dividends, if any.

         9. Any shares of $9 Preferred Stock which shall at any time have been
redeemed, purchased or otherwise acquired by the corporation (whether pursuant
to paragraph 3 or subparagraph (a) of paragraph 5 of this Part A or otherwise)
shall cease to be shares of such series and may not be




                                     -6-
<PAGE>   7
reissued as shares of such series but shall, after such redemption, purchase or
other acquisition, have the status of authorized but unissued shares of the No
Par Value Preferred Stock without designation as to series until once more
designated as part of a particular series by the Board of Directors.

Part B. $2.125 Series No Par Value Preferred Stock, $25 Redemption Value.

         1. There shall be a series of the No Par Value Preferred Stock to be
known as "$2.125 Series No Par Value Preferred Stock, $25 Redemption Value"
(hereinafter referred to as the "$2.125 Preferred Stock"), consisting of
1,340,023 shares of the No Par Value Preferred Stock.

         2. The holders of the $2.125 Preferred Stock shall be entitled to
receive fully cumulative dividends, when and as declared by the Board of
Directors of the corporation out of funds legally available therefor, at the
rate of $2.125 per share, and no more, per annum. Such dividends shall be
payable quarterly on the first day of each March, June, September and December,
commencing on the first of such dates after shares of the $2.125 Preferred
Stock are first issued, and shall be paid to holders of record on such
respective dates which, with respect to the initial quarterly dividend payment
date, shall not be earlier than the date on which shares of such series are
first issued and, with respect to subsequent quarterly dividend payment dates,
shall not exceed 50 days preceding such quarterly dividend payment dates, as
may be determined by the Board of Directors in advance of the payment of the
particular dividend.

         3. The corporation may at any time on or after November 21, 1985
redeem the whole or from time to time any part of the $2.125 Preferred Stock at
$25 per share plus an amount equal to all dividends, if any, accrued thereon to
the date designated for redemption with respect to each share so to be
redeemed, and in addition thereto a premium per share payable upon redemption
over and above the $25 per share and any accrued dividends thereon, as follows:

however, that prior to November 21, 1990, the corporation shall not redeem any
of the $2.125 Preferred Stock at its option, directly or indirectly, from the
proceeds of or in anticipation of any refunding operation involving the
incurring of debt or the issuance of Preferred Stock having a cost to the
corporation, computed in accordance with generally accepted financial practice,
of less than 8 1/2% per annum.

holders of any shares of stock of the corporation ranking junior to the $2.125
Preferred Stock upon liquidation, the holders of the $2.125 Preferred Stock
shall be entitled to receive a payment at the rate of $25 per share, plus an
amount equal to all dividends accrued thereon to the

date of final distribution to such holders; provided, however, that upon any
voluntary liquidation, dissolution or winding up of the corporation (including
any liquidation, dissolution or winding up of the corporation resulting from
government seizure by right of eminent domain), the holders of the $2.125
Preferred Stock shall be entitled to receive at the time thereof, over and
above the amount of $25 per share and any accrued dividends thereon, a premium
per share as follows:

and thereafter a premium per share equal to the then applicable optional
redemption premium fixed in paragraph 3 of this Part B.

         5. (a) On or before December 31, 1985, but not before November 21,
1985, and on or before each December 31 thereafter, the corporation shall
retire through redemption in the manner hereinafter provided a number of shares
of $2.125 Preferred Stock equal to 6 2/3% of the largest number of shares of
such series which shall at any time have been issued and outstanding (such
number to be appropriately adjusted in the event of any stock split,
combination or any other recapitalization or in the event that any shares of
such series are issued after the first date on which shares are selected for
redemption pursuant to this subparagraph (a)), so that all shares of $2.125
Preferred Stock will be redeemed on or before November 21, 2000; provided,
however, that such redemptions may be made only out of the net assets of the
corporation legally available therefor remaining after full cumulative
dividends upon all of the shares of $2.125 Preferred Stock then outstanding to
the end of the last preceding dividend period shall have been paid, or declared
and a sum sufficient for the payment thereof set apart for payment. The number
of shares required to be retired in each year pursuant to this subparagraph (a)
shall be subject to reduction by the application of a credit as provided in
subparagraph (c) of this paragraph 5.

         (b) On each date designated for the redemption of shares of $2.125
Preferred Stock pursuant to subparagraph (a) of this paragraph 5, out of such
net assets, the corporation may at its option and in addition to shares of such
series required to be retired pursuant thereto retire through redemption up to
a number of shares of such series not exceeding the number of shares so
required to be retired annually (prior to the application of any credits);
provided, however, that no shares of such series may be retired pursuant to
this subparagraph (b) when there exists any deficiency in the retirement of
shares pursuant to subparagraph (a) of this paragraph 5. The right to retire
shares pursuant to this subparagraph (b) is noncumulative and to the extent not
exercised in any year shall terminate.

         (c) There shall be allowed to the corporation as a credit against the
number of shares of $2.125 Preferred Stock required to be retired pursuant to
subparagraph (a) of this paragraph 5 for any year or years selected by the
Board of Directors in its discretion shares of such series which the
corporation has at any time theretofore redeemed otherwise than pursuant to
subparagraphs (a) and (b) of this paragraph 5, purchased or otherwise acquired
and canceled and which have not theretofore been used for the purpose of any
such credit.

         (d) The obligation of the corporation to retire shares of $2.125
Preferred Stock pursuant to subparagraph (a) of this paragraph 5 shall be
cumulative, so that, if in any year the corporation shall not retire the number
of shares so required to be retired after the application of the credit
provided for in subparagraph (c) of this paragraph 5, the obligation to retire
such shares shall continue and funds legally available therefor shall be
applied for such purpose until such obligation is discharged.

<PAGE>   9
         (e) Shares of $2.125 Preferred Stock shall be redeemed pursuant to
this paragraph 5 at the redemption price of $25 per share, plus an amount equal
to the dividends accrued thereon to the date designated for redemption. Notice
of redemption of shares pursuant to this paragraph 5 shall be given at least
30, but not more than 50, days in advance of the date designated for
redemption.

         6. If at any time the corporation shall have failed to pay, or declare
and set apart for payment, dividends accrued on the $2.125 Preferred Stock to
the last preceding quarterly dividend payment date, or shall have failed to
redeem, or to set aside funds necessary for the redemption of, the number of
shares required to be redeemed pursuant to subparagraph (a) of paragraph 5 of
this Part B after the application of the credit provided for in subparagraph
(c) of such paragraph 5, thereafter and until such dividends shall have been
paid, or sums sufficient for the payment thereof shall have been set apart for
payment, or until such shares shall have been redeemed, or funds necessary for
the redemption thereof shall have been set aside, as the case may be, (i) the
corporation shall not exercise any optional right to redeem any Preferred Stock
of any other class or series or less than all of the $2.125 Preferred Stock at
the time outstanding and (ii) neither the corporation nor any subsidiary shall
purchase any Preferred Stock except in accordance with a purchase offer made in
writing to all holders of Preferred Stock of all classes and series upon such
terms as the Board of Directors, in its sole discretion after consideration of
the respective annual dividend rates and other relative rights and preferences
of the respective classes and series, shall determine will result in fair and
equitable treatment among the respective series. Nothing in this paragraph 6
shall prevent the corporation from completing the redemption of any Preferred
Stock of any class or series, notice of the redemption of which was mailed
prior to any failure to pay dividends on or redeem shares of the $2.125
Preferred Stock.

         7. So long as any of the $2.125 Preferred Stock is outstanding, the
corporation will not:

         (a) redeem, purchase or otherwise acquire shares of any class or
classes of stock of the corporation ranking junior to the $2.125 Preferred
Stock either as to dividends or upon liquidation if such redemption, purchase
or acquisition complies with the provisions of paragraph 2(a) of Part D of this
Section II only by application of the proviso thereof;

         (b) amend, alter or repeal any of the provisions applicable to the
$2.125 Preferred Stock so as to change the dividend payable thereon, the amount
payable thereon upon liquidation or redemption or the mandatory redemption
provisions applicable thereto without the affirmative vote or consent of the
holders of at least 66 2/3% thereof at the time outstanding, voting as a
separate class, given in person or by proxy, either in writing or by resolution
adopted at a special meeting called for the purpose;

         (c) create any other class or classes of stock ranking prior to the No
Par Value Preferred Stock as to dividends, sinking fund or upon liquidation, or
increase the authorized number of shares of any other class or classes of stock
ranking prior to the No Par Value Preferred Stock, without the affirmative vote
or consent, in addition to all other votes or consents required hereby or by
the laws of the State of Delaware, of the holders of at least a majority of all
the No Par Value Preferred Stock at the time outstanding which shall not by the
terms thereof then or thereafter be convertible into Common Stock, voting
together as a single class separate from the holders of any other class,
classes or series of stock of the corporation, given in person or by proxy,
either in writing or by resolution adopted at a special meeting called for the
purpose; provided, however, that if such other class or classes of stock shall
rank prior to less than all series of the No Par Value Preferred Stock, only
the affirmative vote or consent of at least a majority of the number of shares
at the time outstanding of the series so affected shall be required.

         8. Any shares of $2.125 Preferred Stock which shall at any time have
been redeemed, purchased or otherwise acquired by the corporation (whether
pursuant to subparagraph (a) or (b) of paragraph 5 of this Part B or otherwise)
shall, except for purposes of the credit provided in subparagraph (c) of such
paragraph 5, cease to be shares of such series and may not be reissued as
shares of such series but shall, after such redemption, purchase or other
acquisition, have the status of authorized but unissued shares of the No Par
Value Preferred Stock without designation as to series until once more
designated as part of a particular series by the Board of Directors.

Part C. Other Series of No Par Value Preferred Stock.

         1. The Board of Directors is expressly authorized to adopt, from time
to time, a resolution or resolutions providing for the issue of No Par Value
Preferred Stock in one or more series (in addition to the $9 Preferred Stock and
the $2.125 Preferred Stock), to fix the number of shares in each such series
and to fix the designations and the powers, preferences and relative,
participating, optional or other special rights, and the qualifications,
limitations and restrictions, of each such series.  The authority of the Board
of Directors with respect to each such series shall include determination of
the following (which may vary as between the different series of No Par Value
Preferred Stock):

                 (a) The number of shares constituting the series and the 
         distinctive designation of the series;

                 (b) The dividend rate on the shares of the series and the 
         extent, if any, to which dividends thereon shall be cumulative;

                 (c) Whether shares of the series shall be redeemable and, if
         redeemable, the redemption price payable on redemption thereof, which
         price may, but need not, vary according to the time or circumstances
         of such redemption;

                 (d) The amount or amounts payable upon the shares of the
         series in the event of voluntary or involuntary liquidation,
         dissolution or winding up of the corporation prior to any payment or
         distribution of the assets of the corporation to any class or classes
         of stock of the corporation ranking junior to the Preferred Stock,
         provided, however, that the aggregate amount payable upon the shares
         of all series of No Par Value Preferred Stock upon voluntary or
         involuntary liquidation shall not exceed $500,000,000;

                 (e) Whether the shares of the series shall be entitled to the
         benefit of a sinking or retirement fund to be applied to the purchase
         or redemption of shares of the series and, if so entitled, the amount
         of such fund and the manner of its application, including the price or
         prices at which the shares may be redeemed or purchased through the
         application of such fund;

                 (f) Whether the shares of the series shall be convertible
         into, or exchangeable for, shares of any other class or classes or of
         any other series of the same or any other class or classes of stock of
         the corporation and, if so convertible or exchangeable, the conversion
         price or prices, or the rates of exchange, and the adjustments
         thereof, if any, at which such conversion or exchange may be made, and
         any other terms and conditions of such conversion or exchange;

                 (g) The extent, if any, to which the holders of shares of the
         series shall be entitled to vote on any question or in any proceedings
         or to be represented at or to receive notice of any meeting of
         stockholders of the corporation; and

                 (h) Any other preferences, privileges and powers, and
         relative, participating, optional or other special rights, and
         qualifications, limitations or restrictions of such series, as the
         Board of Directors may deem advisable, which shall not affect
         adversely any other class or series of Preferred Stock at the time
         outstanding and which shall not be inconsistent with the provisions of
         this certificate of incorporation.


Part D. All Series of No Par Value Preferred Stock.

         1. (a) Except as otherwise specifically provided by the laws of the
State of Delaware or by this certificate of incorporation or by the resolution
of the Board of Directors creating any series of No Par Value Preferred Stock,
the holders of the No Par Value Preferred Stock shall not be entitled to vote
on any question or in any proceedings or to be represented at or to receive
notice of any meeting of stockholders of the corporation; provided, however,
that whenever accrued dividends on any series of the No Par Value Preferred
Stock shall not be paid in an aggregate amount equivalent to six full




                                     -10-
<PAGE>   11
quarterly dividends, the holders of the shares of such series shall have the
special right, voting together with the holders of any other series of the No
Par Value Preferred Stock, if they shall then have such right, as a single
class separately from the holders of any other class of stock of the
corporation, to elect at the next annual meeting of the stockholders of the
corporation two directors of the corporation, and the remaining directors shall
be elected by the other class, classes or series of stock entitled to vote
therefor. Such right of election shall continue until such time as all
dividends on the shares of the series having such right accrued to the date of
payment, if the date of payment shall be a quarterly dividend payment date, or
to the last preceding quarterly dividend payment date, if the date of payment
shall be other than a quarterly dividend payment date, shall have been paid in
full, or declared and set apart for payment, at which time such right of
election shall terminate, subject to revesting in the event of each and every
subsequent failure to pay in an aggregate amount equivalent to six full
quarterly dividends. In the exercise of the special voting rights provided in
this paragraph 1, the holders of shares shall have one vote per share. Nothing
herein contained shall in any way restrict the power of the Board of Directors
to increase or decrease the number of directors in accordance with the laws of
the State of Delaware, this certificate of incorporation and the By-Laws of the
corporation.

         (b) At any annual meeting of stockholders at which holders of any
series of the No Par Value Preferred Stock shall have the right of election
provided in this paragraph 1, the presence, in person or by proxy, of the
holders of a majority of the shares of No Par Value Preferred Stock entitled to
participate in such election shall be required to constitute a quorum of such
shares for the election of any director by the holders of such shares. At any
such meeting or adjournment thereof, (i) the absence of a quorum of such shares
of No Par Value Preferred Stock shall not prevent the election of the directors
to be elected by the other class, classes or series of stock entitled to vote
therefor, and the absence of a quorum of such other class, classes or series of
stock shall not prevent the election of the directors to be elected by such
shares of No Par Value Preferred Stock, and (ii) in the absence of either or
both such quorums, a majority of the holders present in person or by proxy of
the class, classes or series of stock which lack a quorum shall have power to
adjourn the meeting for the election of directors which they are entitled to
elect, from time to time, without notice other than announcement at the
meeting, until a quorum shall be present.

         (c) The directors elected by the holders of shares of No Par Value
Preferred Stock in exercise of the right of election provided in this paragraph
1 shall continue in office until their successors shall have been elected by
such holders or until termination of such right of election. The vacancies in
the Board of Directors so occurring upon the termination of such right of
election shall be filled by the majority vote of the remaining directors. Any
vacancies in the Board of Directors occurring during any period when the
holders of shares of No Par Value Preferred Stock have such right of election
shall be filled only by vote of a majority (even if that be only a single
director) of the remaining directors theretofore elected by the holders of the
class, classes or series of stock which elected the director whose office shall
have become vacant.

         2. Except as otherwise specifically provided with respect to any
series of No Par Value Preferred Stock, so long as any of the No Par Value
Preferred Stock is outstanding, the corporation will not:

                 (a) declare or pay, or set apart for payment, any dividends
         (other than dividends payable in shares of stock of the corporation
         ranking junior to the No Par Value Preferred Stock, both as to
         dividends and upon liquidation) or make any distribution, on any class
         or classes of stock of the corporation ranking junior to the No Par
         Value Preferred Stock either as to dividends or upon liquidation, and
         will not redeem, purchase or otherwise acquire, whether voluntarily,
         for a mandatory or optional sinking or retirement fund or otherwise,
         or permit any subsidiary to purchase or otherwise acquire, any shares
         of any such junior class if at the time of making such declaration,
         payment, distribution, redemption, purchase or acquisition the
         corporation shall not have paid, or declared and set apart for
         payment, all dividends accrued on the No Par Value




                                     -11-
<PAGE>   12
         Preferred Stock to the date of such declaration, payment,
         distribution, redemption, purchase or acquisition, if such date shall
         be a quarterly dividend payment date, or to the last preceding
         quarterly dividend payment date, if such date shall be other than a
         quarterly dividend payment date, or shall not have redeemed, or set
         aside funds necessary for the redemption of, any shares of No Par
         Value Preferred Stock required to be redeemed pursuant to this
         certificate of incorporation or the resolution or resolutions of the
         Board of Directors creating any series of No Par Value Preferred
         Stock; provided, however, that the corporation may at any time redeem,
         purchase or otherwise acquire shares of any such junior class in
         exchange for, or out of the net cash proceeds from the substantially
         concurrent sale of, shares of any class of stock of the corporation
         ranking junior to the No Par Value Preferred Stock both as to
         dividends and upon liquidation;

                (b) without the affirmative vote or consent of the holders of
         at least 66 2/3% of all the No Par Value Preferred Stock at the time
         outstanding, voting together as a single class separate from the
         holders of any other class of stock of the corporation, given in
         person or by proxy, either in writing or by resolution adopted at a
         special meeting called for the purpose, (i) create any other class or
         classes of stock ranking prior to the No Par Value Preferred Stock,
         either as to dividends or upon liquidation, or increase the authorized
         number of shares of any such other class of stock or (ii) amend, alter
         or repeal any of the provisions of this Article so as to affect
         adversely the preferences, special rights or powers of the No Par
         Value Preferred Stock; provided, however, that if such amendment,
         alteration or repeal affects adversely the preferences, special rights
         or powers of one or more but not all series of No Par Value Preferred
         Stock at the time outstanding, only the affirmative vote or consent of
         at least 66 2/3% of the number of shares at the time outstanding of
         the series so affected shall be required; and provided, further, that
         no vote or consent of the No Par Value Preferred Stock shall be
         required to increase the authorized amount of the No Par Value
         Preferred Stock or for the creation of one or more classes of
         preferred stock so long as such class or classes do not rank prior to
         the No Par Value Preferred Stock, either as to dividends or upon
         liquidation;

                (c) without the affirmative vote or consent of the holders of
         at least a majority of all the No Par Value Preferred Stock at the
         time outstanding, voting together as a single class separately from
         the holders of any other class of stock of the corporation, given in
         person or by proxy, either in writing or by resolution adopted at a
         special meeting called for the purpose, voluntarily dissolve,
         liquidate or wind up.

            SECTION III--PROVISIONS RELATING TO ALL PREFERRED STOCK

         1. All shares of Preferred Stock shall be of equal rank as to dividends
and as to distribution upon liquidation, dissolution or winding up except to
the extent otherwise provided with respect to any series of the No Par Value
Preferred Stock by the resolution or resolutions of the Board of Directors
creating such series. If dividends shall at any time be declared or paid on
shares of the Preferred Stock which are of equal rank as to dividends in any
amount less than the full dividends accrued and unpaid to and including the
date of such declaration or payment on all such outstanding shares, such
dividends shall be divided among such shares of Preferred Stock in proportion
to the aggregate amounts of dividends accrued and unpaid to such date on all
such outstanding shares. If, upon any liquidation, dissolution or winding up of
the corporation, the assets of the corporation, or proceeds thereof,
distributable among the holders of the shares of Preferred Stock which are of

         2. The provisions of this paragraph 2 shall be applicable, except to
the extent otherwise provided with respect to any series of No Par Value
Preferred Stock in the resolution or resolutions of the Board of Directors
creating such series, to the redemption of any Preferred Stock which is
redeemable under this certificate of incorporation or the resolution or
resolutions of the Board of Directors creating any series of the No Par Value
Preferred Stock:

                 (a) In the case of any redemption of Preferred Stock, whether
         with or without premium, notice of redemption shall be mailed at least
         30 days in advance of the date designated for such redemption to the
         holders of record of the shares of Preferred Stock so to be redeemed
         at their respective addresses as the same shall appear on the books of
         the corporation.  In order to facilitate the redemption of any shares
         of Preferred Stock that may be selected for redemption as provided in
         this paragraph 2, the Board of Directors is authorized to cause the
         transfer books of the corporation to be closed as to such shares at
         any time not exceeding 50 days prior to the date designated for
         redemption thereof. In case of the redemption of less than all of the
         $10 Par Value Preferred Stock or of any particular series of the No
         Par Value Preferred Stock at the time outstanding, the shares so to be
         redeemed shall be selected by lot or in such other equitable manner as
         the Board of Directors may determine.

                 (b) If notice shall have been given as aforesaid, and if on or
         before the redemption date the funds necessary for such redemption
         shall have been set aside by the corporation, separate and apart from
         its other funds, for the pro rata benefit of the holders of the shares
         so called for redemption, then, notwithstanding that any certificates
         for shares of Preferred Stock so called for redemption shall not have
         been surrendered for cancellation, the shares represented thereby
         shall no longer be deemed outstanding, the right to receive dividends
         thereon shall cease to accrue from and after the date for redemption
         so designated and all rights of holders of the shares of Preferred
         Stock so called for redemption shall forthwith, after such redemption
         date, cease and terminate, except the right of the holders thereof to
         receive the amount payable to them upon such redemption, without
         interest, and except the right, if any, of the holders of such shares
         to convert such shares on or before the third day prior to the date
         designated for such redemption or any other date (not later than the
         date designated for such redemption) specified in the resolution or
         resolutions of the Board of Directors creating the series of Preferred
         Stock of which such shares are a part. Any moneys so set aside by the
         corporation and unclaimed at the end of six years from the date fixed
         for such redemption shall revert to the general funds of the
         corporation after which reversion the holders of such shares so called
         for redemption shall look only to the corporation for payment of the
         amount payable to them upon such redemption and such shares shall
         still not be deemed to be outstanding.  Any moneys so set aside by the
         corporation which shall not be required for such redemption because of
         the exercise of any conversion right of any shares to be redeemed
         shall revert to the general funds of the corporation forthwith.

         3. No holder of Preferred Stock as such shall have any preemptive
right to subscribe to stock, obligations, warrants, rights to subscribe to
stock or other securities of the corporation of any class, whether now or
hereafter authorized.

         4. Except as otherwise provided in the resolution or resolutions of
the Board of Directors creating a series of No Par Value Preferred Stock,
dividends on all shares of Preferred Stock shall be cumulative:

                 (a) in the case of shares of Preferred Stock issued upon the
         merger of a wholly-owned subsidiary of the corporation into Burlington
         Northern Inc., a Delaware corporation which changed its name to
         Burlington Northern Railroad Company (hereinafter referred to as the
         "Railroad Company") coincident with such merger, from the last
         dividend payment date to which dividends have been paid in full, or
         declared and set apart for payment, on the shares of preferred stock
         of the Railroad Company in respect of which such shares of Preferred
         Stock have been issued or from the last dividend payment date to which
         dividends have been paid in full, or




                                     -13-
<PAGE>   14
         declared and set apart for payment, on such shares of Preferred
         Stock, whichever is later; provided, however, that if any shares of
         preferred stock of the Railroad Company are issued after the record
         date for the determination of holders entitled to receive dividends on
         such last dividend payment date, dividends on shares of Preferred
         Stock issued in respect thereof shall be cumulative from the date of
         issue of such preferred stock of the Railroad Company or from the last
         dividend payment date to which dividends have been paid in full, or
         declared and set apart for payment, on such shares of Preferred Stock,
         whichever is later; and

                  (b) in the case of all other shares of Preferred Stock, from
         the date on which such shares are first issued and sold or from the
         last dividend payment date to which dividends have been paid in full,
         or declared and set apart for payment, whichever is later.

         5. For the purposes of this Article:

                  (a) The term "subsidiary" shall mean any corporation of which
         the corporation, directly or indirectly, owns or controls such number
         of shares of outstanding stock as have ordinary voting power to elect
         a majority of the board of directors of such corporation;

                  (b) The term "outstanding", when used in reference to shares
         of stock, shall mean issued shares, excluding shares held by the
         corporation or a subsidiary and shares called for redemption funds for
         the redemption of which shall have been set aside in accordance with
         paragraph 2 of this Section III;

                  (c) The amount of dividends "accrued" on any share of 
         Preferred Stock at any quarterly dividend payment date shall be the 
         amount of any unpaid dividends accumulated thereon to and including 
         such quarterly dividend payment date, whether or not earned or 
         declared and whether or not there shall be funds legally available 
         for the payment of dividends thereon, and the amount of dividends 
         "accrued" on any share of Preferred Stock as at any date other than a 
         quarterly dividend payment date shall be the amount of dividends 
         accrued thereon at the last preceding quarterly dividend payment date 
         plus a pro rata portion of the annual dividend for the period after 
         such last preceding quarterly dividend payment date to and including 
         the date as of which the calculation is made, calculated on the 
         basis of a 360-day year of twelve 30-day months.

                  (d) Any class, classes or series of stock of the corporation
         shall be deemed to rank

                           (i) prior to any other class, classes or series of
                   stock of the corporation either as to dividends or upon
                   liquidation if the holders of such class, classes or series
                   shall be entitled to the receipt of dividends or of amounts
                   distributable upon liquidation, dissolution or winding up,
                   as the case may be, in preference or priority to the holders
                   of the class, classes or series as to which such
                   determination is being made;

                           (ii) junior to any class, classes or series of
                   stock of the corporation either as to dividends or upon
                   liquidation if the rights of the holders of such class,
                   classes or series shall be subject or subordinate to the
                   rights of the holders of the class, classes or series as to
                   which such determination is being made in respect of the
                   receipt of dividends or of amounts distributable upon

Board of Directors:

         RESOLVED, that, pursuant to the authority expressly granted by the
Certificate of Incorporation, as amended, of the Company, there is hereby
created a series of the No Par Value Preferred Stock consisting of 7,436,354
shares, the issuance of which is hereby authorized, which shall be designated

as the "Adjustable Rate Preferred Stock") and which shall have a stated value
of $48 per share and the following powers, preferences and relative,
participating, optional or other special rights and qualifications, limitations
and restrictions in addition to those set forth in the Certificate of
Incorporation, as amended, of the Company

         1.  (a) The holders of the Adjustable Rate Preferred Stock shall be
entitled to receive fully cumulative dividends, when and as declared by the
Board of Directors of the Company out of funds legally available therefor, at
the following rates per share (i) for the period (the "Initial Dividend 
Period") from the date of their original issue to and including February 29,
1984, at a rate per annum of 11.20% on the stated value thereof, and (ii) for
each quarterly dividend period (hereinafter referred to as a "Quarterly
Dividend Period", the Initial Dividend Period or any Quarterly Dividend Period
being hereinafter individually referred to as a "Dividend Period", thereafter,
which Quarterly Dividend Periods shall commence on March 1, June 1, September 1
and December 1 in each year and shall end on and include the day next preceding
the first day of the next Quarterly Dividend Period, at a rate per annun on the
stated value thereof equal to the Applicable Rate (as defined in paragraph (b)
of the Section 1) in respect of such Quarterly Dividend Period. Such dividends
shall be payable quarterly on the first day of each March, June, September and
December commencing on the first of such dates to occur after shares of the
Adjustable Rate Preferred Stock are first quarterly dividend payment date,
shall not be earlier than the date on which shares of such series are first
issued and, with respect to subsequent quarterly dividend payment dates, shall
not exceed 50 days preceding such quarterly dividend payment dates, as may be
determined by the Board of Directors in advance of the payment of the particular
dividend. Dividends shall commence to accrue from the date of original issuance
of the Adjustable Rate Preferred Stock

         (b) Except as provided below in the paragraph, the "Applicable Rate"
for any Quarterly Dividend Period shall be (i) 75% less than (ii) the highest
of the Treasury Bill Rate, the Ten Year Constant Maturity Rate or the Twenty
Year Constant Maturity Rate (each as hereinafter defined) for such Quarterly
Dividend Period. In the event that the Company determines, after compliance
with the procedures set forth below for determination of the Treasury Bill
Rate, Ten Year Constant Maturity Rate and Twenty Year Constant Maturity Rate,
in good faith that for any reason

             (A) any one of the Treasury Bill Rate, the Ten Year Constant
Maturity Rate and the Twenty Year Constant Maturity Rate cannot be determined
for any Quarterly Dividend Period then the applicable
<PAGE>   24
Rate for such Quarterly Dividend Period shall be .79% less then the higher of
whichever two of such Rates can be so determined:

                  (B) only one of the Treausry Bill Rate, the Ten Year Constant
         Maturity Rate and the Twenty Year Constant Maturity Rate can be 
         determined for any Quarterly Dividend Period, then the Applicable Rate
         for such Quarterly Dividend Period shall be .75% less than whichever 
         such Rate can be so determined; or      

                  (C) some of the Treasury Bill Rate, the Ten Year Constant 
         Maturity Rate and the Twenty Year Constant Maturity Rate can be 
         determined for any Quarterly Dividend Period, then the Applicable Rate
         in effect for the preceding Quarterly Dividend Period shall be 
         continued for such Quarterly Dividend Period.

Anything herein to the contrary notwithstanding, the Applicable Rate for any
Quarterly Dividend Period shall in no event be less than 8.75% per annum or
greater than 12.5% per annum.

         (c) Except as provided blow in this paragraph, the "Treasury BIll
Rate" for each Quarterly Dividend Period shall be the arithmetic average of
the two most recent weekly per annum market discount rates, (or the one weekly
per annum market discount rate, if only one such rate shall be published during
the relevant Calendar Period (as defined below)) for three-month U.S. Treasury
bills as published weekly by the Federal Reserve Board during the Calendar
Period immediately prior to the last ten calendar days of February, May, August
or November, as the case may be, prior to the Quarterly Dividend Period for
which the dividend rate on the Adjustable Rate Preferred Stock is being
determined. In the event that the Federal Reserve Board does not publish such a
weekly per annum market discount rate during such Calendar Period, then the
Treausry Bill Rate for such Quarterly Dividend Period shall be the arithmetic
average of the two most recent weekly per annum market discount rates (or the
one weekly per annum market discount rate, if only one such rate shall be
published during the relevant Calendar Period for three-month U.S. Treasury
bills, as published weekly during such Calendar Period by any Federal Reserve
Bank or by any U.S. Government Department or agency selected by the Company. In
the event that a per annum market discount rate for three-month U.S. Treasury
bills shall not be published by the Federal Reserve Board or by any Federal
Reserve Bank or by any U.S. Government department or agency during such
Calendar Period, then the Treasury Bill Rate for such Quarterly Dividend Period
shall be the arithmetic average of the two most recent weekly per annum market
discount rates (or the one weekly per annum market discount rate, if only one
such rate shall be published during the relevant Calendar Period as provided 
below) for all of the U.S. Treasury bills then having maturities of not less
than 90 nor more than 100 days, as published during such Calendar Period by the
Federal Reserve Board or, if the Federal Reserve Board shall not publish such
rates, by any Federal Reserve Bank or by any U.S. Government department or
agency selected by the Company. In the event that the Company determines in
good faith that for any reason no such U.S. Treasury bill rates are published
as provided above during such Calendar Period, then the Treasury Bill Rate for
such Quarterly Dividend Period shall be the arithmetic average of the per annum
market discount rates based upon the closing bids during such Calendar Period
for each of the issues of marketable noninterest bearing U.S. Treasury
securities with a maturity of not less than 80 nor more than 100 days from the
date of each such quotation, as chosen and quoted daily for each business day
in New York City or less frequently if daily quotations shall not be generally
available) to the Company by at least three recognized dealers in U.S.
Government securities selected by the Company. In the event that the Company
determines in good faith that for any reason the Company cannot determine the
Treasury Bill Rate for any Quarterly Dividend Period as provided above in this
paragraph, the Treasury BIll Rate for such Quarterly Dividend Period shall be
the arithmetic average of the per annum market discount rates based upon the
closing bids during such Calendar Period for each of the issues of marketable

the case may be, prior to the Quarterly Dividend Period for which the dividend
rate on the Adjustable Rate Preferred Stock is being determined. In the event
that the Federal Reserve Board does not publish such a weekly per annum Ten
Year Average Yield during such Calendar Period, then the Ten Year Constant

weekly per annum Ten Year Average Yield, if only one such Yield shall be
published during the relevant Calendar Period as provided below), as published
weekly during such Calendar Period by any Federal Reserve Bank or by any U.S.
Government department or agency selected by the Company. In the event that a
per annum Ten Year Average Yield shall not be published by the Federal Reserve
Board or by any Federal Reserve Bank or by any U.S. Government department or
agency during such Calendar Period, then the Ten Year Constant Maturity Rate
for such Quarterly Dividend Period shall be the arithmetic average of the two
most recent weekly per annum average yields to maturity (or the one weekly

years, as published during such Calendar Period by the Federal Reserve Board
or, if the Federal Reserve Board shall not publish such yields, by any Federal
Reserve Bank or by any U.S. Government department or agency selected by the

reason the Company cannot determine the Ten Year Constant Maturity Rate for any
Quarterly Dividend Period as provided above in this paragraph, then the Ten
Year Constant Maturity Rate for such Quarterly Dividend Period shall be the
arithmetic average of the per annum average yields to maturity based upon the
closing bids during such Calendar Period for each of the issues of actively

or November, as the case may be, prior to the Quarterly Dividend Period for
which the dividend rate on the Adjustable Rate Preferred Stock is being
determined. In the event that the Federal Reserve Board does not publish such a
weekly per annum Twenty Year Average Yield during such Calendar Period, then
the Twenty Year Constant Maturity Rate for such Dividend Period shall be the
arithmetic average of the two most recent weekly per annum Twenty Year Average
Yields (or the one weekly per annum Twenty Year Average Yield, if only one such
Yield shall be published during the relevant Calendar Period as provided
below), as published weekly during such Calendar Period by any Federal Reserve

the event that a per annum Twenty Year Average Yield shall not be published by

arithmetic average of the two most recent weekly per annum average yields to
maturity (or the one weekly average yield to maturity, if only one such yield

         any kind, together with any Affiliate of such person or entity, or any
         person or entity with whom such person, entity or an Affiliate has any

                 (d)      A "Disinterested Director" is a member of the Board
         of Directors of the corporation (other than the Interested
         Stockholder) who was a director prior to the
<PAGE>   41
         time the Interested Stockholder became an Interested Stockholder, or
         any director who was recommended for election by the Disinterested
         Directors.  Any action to be taken by the Disinterested Directors
         shall require the affirmative vote of at least two-thirds of the

         pursuant to a stock split, stock dividend or distribution of warrants
         or rights; (iv) the adoption of any plan or proposal for the
         liquidation or dissolution of the corporation proposed by or on behalf
         of an Interested Stockholder; (v) any reclassification of securities,
         recapitalization, merger or consolidation or other transaction which
         has the effect, directly or indirectly, of increasing the
         proportionate share of any Voting Stock beneficially owned by an
         Interested Stockholder; or (vi) any agreement, contract or other
         arrangement providing for any of the foregoing transactions.

                 (f)      A "Substantial Part of the corporation's Assets"
         shall mean assets of the corporation or any of its subsidiaries in an

         determination is made.

Section II--Vote Required for Business Combinations

         The affirmative vote of not less than fifty-one percent of the Voting
Stock, excluding the Voting Stock of an Interested Stockholder who is a party
to the Business Combination, shall be required for the adoption or
authorization of a Business Combination, unless the Disinterested Directors
determine that:

                 (a)      The Interested Stockholder is the beneficial owner of
         not less than eighty percent of the Voting Stock





                                     -2-
<PAGE>   42
         and has declared its intention to vote in favor of or approve such
         Business Combination; or

                 (b) (i) The fair market value of the consideration per
         share to be received or retained by the holders of each class or
         series of stock of the corporation in a Business Combination is equal
         to or greater than the consideration per share (including brokerage
         commissions and soliciting dealer's fees) paid by such Interested
         Stockholder in acquiring the largest number of shares of such class of
         stock previously acquired in any one transaction or series of related
         transactions, whether before or after the Interested Stockholder
         became an Interested Stockholder and (ii) the Interested Stockholder
         shall not have received the benefit, directly or indirectly (except
         proportionately as a stockholder), of any loans, advances, guarantees,

         whether in anticipation of or in connection with such Business
         Combination or otherwise.

Section III--Information Requirements

         In the event any vote of holders of Voting Stock is required for the
adoption or approval of any Business Combination, a proxy or information
statement describing the Business Combination and complying with the
requirements of the 1934 Act shall be mailed at a date determined by the
Disinterested Directors to all stockholders of the corporation whether or not
such statement is required under the 1934 Act.  The statement shall contain any
recommendations as to the advisability of the Business Combination which the
Disinterested Directors, or any of them, may choose to state and, if deemed
advisable by the Disinterested Directors, an opinion of an investment banking
firm as to the fairness of the terms of such Business Combination. Such firm
shall be selected by the Disinterested Directors and paid a fee for its
services by the corporation as approved by the Disinterested Directors.

         2.      a new Article SEVENTH is added to read as follows:

         SEVENTH.         Any action by stockholders of the corporation shall
be taken at a meeting of stockholders and no action may be taken by written
consent of stockholders entitled to vote upon such action.  No amendment to the
Certificate of Incorporation shall amend, alter, change or repeal any of the
provisions of Article SIXTH hereof or of this Article SEVENTH





                                     -3-
<PAGE>   43
unless such amendment shall receive the affirmative vote of not less than
fifty-one percent of the Voting Stock, excluding the Voting Stock of any
Interested Stockholder as defined in Article SIXTH.

         3.      the present Articles SIXTH, SEVENTH, EIGHTH and NINTH are
                 renumbered EIGHTH, NINTH, TENTH and ELEVENTH, respectively.

              CERTIFICATE OF DESIGNATION,  PREFERENCES AND RIGHTS
            OF SERIES A JUNIOR PARTICIPATING CLASS A PREFERRED STOCK

                                       Of

                            BURLINGTON NORTHERN INC.

             Pursuant to Section 151 of the General Corporation Law
                            of the State of Delaware

         We, James W. Becker, Vice President, Law and Leslie S. Gibbs,
Corporate Secretary, of Burlington Northern Inc., a corporation organized and
existing under the General Corporation Law of the State of Delaware,  in
accordance with the provisions of Section 103 thereof, DO HEREBY CERTIFY:

         That pursuant to the authority conferred upon the Board of Directors
by the Certificate of Incorporation of the said Corporation, the said Board of
Directors on July 10,  1986, adopted the following resolution creating a series
of 800,000 shares of Class A Preferred Stock Without Par Value designated as
Series A Junior Participating Class A Preferred Stock:

         RESOLVED,  that pursuant to the authority vested in the Board of
Directors of this Corporation in accordance with the provisions of its
Certificate of Incorporation, a series of Preferred Stock of the Corporation be
and it hereby is created, and that the designation and amount thereof and the
voting powers, preferences and relative, participating, optional and other
special rights of the shares of such series, and the qualifications,
limitations or restrictions thereof are as follows:

         Section 1.   Designation and Amount.   There shall be a series of the
Class A Preferred Stock Without Par Value of the Company which shall be
designated as the "Series A Junior Participating Class A Preferred Stock," no
par value,  and the number of shares constituting such series shall be 800,000.
Such number of shares may be increased or decreased by resolution of the Board
of Directors; provided,  that no decrease shall reduce the number of shares of
Series A Junior Participating Class A Preferred Stock to a number less than
that of the shares then outstanding plus the number of shares issuable upon
exercise of outstanding rights, options of
<PAGE>   45
warrants or upon conversion of outstanding securities issued by the Company.

         Section 2.   Dividends and Distributions.

         (A)   Subject to the prior and superior rights of the holders of any
shares of any series of Class A Preferred Stock Without Par Value (the
"Preferred Stock") or any other preferred stock of the Company ranking prior
and superior to the shares of Series A Junior Participating Class A Preferred
Stock with respect to dividends, the holders of shares of Series A Junior
Participating Class A Preferred Stock, in preference to the holders of shares
of Common Stock, without par value (the "Common Stock"), of the Company and any
other junior stock, shall be entitled to receive, when, as and if declared by
the Board of Directors out of funds legally available for the purpose,
quarterly dividends payable in cash on the first day of March, June, September
and December in each year (or,  in each case,  if not a date on which the
Company is open for business, the next date on which the Company is so open)
(each such date being referred to herein as a "Quarterly Dividend Payment
Date"), commencing on the first Quarterly Dividend Payment Date after the first
issuance of a share or fraction of a share of Series A Junior Participating
Class A Preferred Stock,  in an amount per share (rounded to the nearest cent)
equal to the greater of (a) $10.00 or (b) subject to the provision for
adjustment hereinafter set forth, 100 times the aggregate per share amount of
all cash dividends, and 100 times the aggregate per share amount (payable in
kind) of all non-cash dividends or other distributions other than a dividend
payable in shares of Common Stock or a subdivision of the outstanding shares of
Common Stock (by reclassification or otherwise), declared on the Common Stock,
since the immediately preceding Quarterly Dividend Payment Date, or, with
respect to the first Quarterly Dividend Payment Date, since the first issuance
of any share or fraction of a share of Series A Junior Participating Preferred
Stock.   In the event the Company shall at any time after July 24,  1986 (the
"Rights Declaration Date") (i) declare any dividend on Common Stock payable in
shares of Common Stock,  (ii) subdivide the outstanding Common Stock, or (iii)
combine the outstanding Common Stock into a smaller number of shares,  then in
each such case the amount to which holders of shares of Series A Junior
Participating Class A Preferred Stock were entitled immediately prior to such
event under clause (b) of the preceding sentence shall be adjusted by
multiplying such amount by a fraction the numerator of which is the number of
shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of





                                       2
<PAGE>   46
shares of Common Stock that were outstanding immediately prior to such event.

         (B)   The Company shall declare a dividend or distribution on the
Series A Junior Participating Class A Preferred Stock as provided in paragraph
(A)  above immediately after it declares a dividend or distribution on the
Common Stock (other than a dividend payable in shares of Common Stock);
provided that, in the event no dividend or distribution shall have been
declared on the Common Stock during the period between any Quarterly Dividend
Payment Date and the next subsequent Quarterly Dividend Payment Date, a
dividend of $10.00 per share on the Series A Junior Participating Class A
Preferred Stock shall nevertheless be payable on such subsequent Quarterly
Dividend Payment Date.

         (C)   Dividends shall begin to accrue and be cumulative on outstanding
shares of Series A Junior Participating Class A Preferred Stock from the
Quarterly Dividend Payment Date next preceding the date of issue of such shares
of Series A Junior Participating Class A Preferred Stock, unless the date of
issue of such shares is prior to the record date for the first Quarterly
Dividend Payment Date,  in which case dividends on such shares shall begin to
accrue from the date of issue of such shares, or unless the date of issue is a
Quarterly Dividend Payment Date or is a date after the record date for the
determination of holders of shares of Series A Junior Participating Class A
Preferred Stock entitled to receive a quarterly dividend and before such
Quarterly Dividend Payment Date in either of which events such dividends shall
begin to accrue and be cumulative from such Quarterly Dividend Payment Date.
Accrued but unpaid dividends shall not bear interest. Dividends paid on the
shares of Series A Junior Participating Class A Preferred Stock in an amount
less than the total amount of such dividends at the time accrued and payable on
such shares shall be allocated pro rata on a share-by-share basis among all
such shares at the time outstanding. The Board of Directors may fix a record
date for the determination of holders of shares of Series A Junior
Participating Class A Preferred Stock entitled to receive payment of a dividend
or distribution declared thereon, which record date shall be no more than 30
days prior to the date fixed for the payment thereof.

         Section 3.   Voting Rights.   The holders of shares of Series A Junior
Participating Class A Preferred Stock shall have the following voting rights:

         (A)   Subject to the provision for adjustment hereinafter set forth,
each share of Series A Junior





                                       3
<PAGE>   47
Participating Class A Preferred Stock shall entitle the holder thereof to 100
votes on all matters submitted to a vote of the stockholders of the Company.
In the event the Company shall at any time after the Rights Declaration Date
(i) declare any dividend on Common Stock payable in shares of Common Stock,
(ii) subdivide the outstanding Common Stock, or (iii) combine the outstanding
Common Stock into a smaller number of shares, then in each such case the number
of votes per share to which holders of shares of Series A Junior Participating
Class A Preferred Stock were entitled immediately prior to such event shall be
adjusted by multiplying such number by a fraction the numerator of which is the
number of shares of Common Stock outstanding immediately after such event and
the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

         (B)   Except as otherwise provided herein or by law, the holders of
shares of Series A Junior Participating Class A Preferred Stock and the holders
of shares of Common Stock shall vote together as one class on all matters
submitted to a vote of stockholders of the Company.

         (C)  (i)  If at any time dividends on any Series A Junior
Participating Class A Preferred Stock shall be in arrears in an amount equal to
six (6) quarterly dividends thereon, the occurrence of such contingency shall
mark the beginning of a period (herein called a "default period") which shall
extend until such time when all accrued and unpaid dividends for all previous
quarterly dividend periods and for the current quarterly dividend period on all
shares of Series A Junior Participating Class A Preferred Stock then
outstanding shall have been declared and paid or set apart for payment. During
each default period, all holders of Preferred Stock (including holders of the
Series A Junior Participating Class A Preferred Stock) with dividends in
arrears in an amount equal to six (6) quarterly dividends thereon, voting as a
class, irrespective of series, shall have the right to elect two (2) Directors.

         (ii)     During any default period, such voting right of the holders
of Series A Junior Participating Class A Preferred Stock may be exercised
initially at a special meeting called pursuant to subparagraph (iii) of this
Section 3(C) or at any annual meeting of stockholders,  and thereafter at
annual meetings of stockholders, provided that neither such voting right nor
the right of the holders of any other series of Preferred Stock,  if any,  to
increase,  in certain cases,  the authorized number of Directors shall be
exercised unless the holders of ten percent (10%)  in number of shares of
Preferred Stock outstanding shall be present in person or by proxy.   The





                                       4
<PAGE>   48
absence of a quorum of the holders of Common Stock shall not affect the
exercise by the holders of Preferred Stock of such voting right.  At any
meeting at which the holders of Preferred Stock shall exercise such voting
right initially during an existing default period, they shall have the right,
voting as a class,  to elect Directors to fill such vacancies,  if any,  in the
Board of Directors as may then exist up to two (2) Directors or,  if such right
is exercised at an annual meeting, to elect two (2) Directors.   If the number
which may be so elected at any special meeting does not amount to the required
number, the holders of the Preferred Stock shall have the right to make such
increase in the number of Directors as shall be necessary to permit the
election by them of the required number.  After the holders of the Preferred
Stock shall have exercised their right to elect Directors in any default period
and during the continuance of such period,  the number of Directors shall not
be increased or decreased except by vote of the holders of Preferred Stock as
herein provided or pursuant to the rights of any equity securities ranking
senior to or pari passu with the Series A Junior Participating Class A
Preferred Stock.

         (iii)     Unless the holders of Preferred Stock shall, during an
existing default period, have previously exercised their right to elect
Directors, the Board of Directors may order, or any stockholder or stockholders
owning in the aggregate not less than ten percent (10%) of the total number of
shares of Preferred Stock outstanding,  irrespective of series, may request,
the calling of special meeting of the holders of Preferred Stock, which meeting
shall thereupon be called by the President, a Vice-President or the Secretary
of the Company.   Notice of such meeting and of any annual meeting at which
holders of Preferred Stock are entitled to vote pursuant to this paragraph
(C)(iii) shall be given to each holder of record of Preferred Stock by mailing
a copy of such notice to him at his last address as the same appears on the
books of the Company.  Such meeting shall be called for a time not earlier than
20 days and not later than 60 days after such order or request or in default of
the calling of such meeting within 60 days after such order or request,  such
meeting may be called on similar notice by any stockholder or stockholders
owning in the aggregate not less than ten percent (10%) of the total number of
shares of Preferred Stock outstanding. Notwithstanding the provisions of this
paragraph (C)(iii), no such special meeting shall be called during the period
within 60 days immediately preceding the date fixed for the next annual meeting
of the stockholders.

         (iv)     In any default period,  the holders of Common Stock, and
other classes of stock of the Company if applicable,





                                       5
<PAGE>   49
shall continue to be entitled to elect the whole number of Directors until the
holders of Preferred Stock shall have exercised their right to elect two (2)
Directors voting as a class, after the exercise of which right (x) the
Directors so elected by the holders of Preferred Stock shall continue in office
until their successors shall have been elected by such holders or until the
expiration of the default period,  and (y) any vacancy in the Board of
Directors may (except as provided in paragraph (C)(ii) of this Section 3) be
filled by vote of a majority of the remaining Directors theretofore elected by
the holders of the class of stock which elected the Director whose office shall
have become vacant.   References in this paragraph (C) to Directors elected by
the holders of a particular class of stock shall include Directors elected by
such Directors to fill vacancies as provided in clause (y) of the foregoing
sentence.

         (v)     Immediately upon the expiration of a default period,  (x) the
right of the holders of Preferred Stock as a class to elect Directors shall
cease,  (y) the term of any Directors elected by the holders of Preferred Stock
as a class shall terminate, and (z) the number of Directors shall be such
number as may be provided for in the Certificate of Incorporation or By-laws
irrespective of any increase made pursuant to the provisions of paragraph
(C)(ii) of this Section 3 (such number being subject, however to change
thereafter in any manner provided by law or in the Certificate of Incorporation
or By-laws).   Any vacancies in the Board of Directors effected by the
provisions of clauses (y) and (z)  in the preceding sentence may be filled by a
majority of the remaining Directors.

         (D)   Except as set forth herein, holders of Series A Junior
Participating Class A Preferred Stock shall have no special voting rights and
their consent shall not be required (except to the extent they are entitled to
vote with holders of Common Stock as set forth herein) for taking any corporate
action.

         Section 4. Certain Restrictions.

         (A)  Whenever quarterly dividends or other dividends or distributions
payable on the Series A Junior Participating Class A Preferred Stock as
provided in Section 2 are in arrears,  thereafter and until all accrued and
unpaid dividends and distributions, whether or not declared, on shares of
Series A Junior Participating Class A Preferred Stock outstanding shall have
keen paid in full,  the Company shall not





                                       6
<PAGE>   50
                 (i)   declare or pay dividends on, make any other
         distributions on, or redeem or purchase or otherwise acquire for
         consideration any shares of stock ranking junior (either as to
         dividends or upon liquidation, dissolution or winding up) to the
         Series A Junior Participating Class A Preferred Stock;

                 (ii)   declare or pay dividends on or make any other
         distributions on any shares of stock ranking on a parity (either as to
         dividends or upon liquidation, dissolution or winding up) with the
         Series A Junior Participating Class A Preferred Stock, except
         dividends paid ratably on the Series A Junior Participating Class A
         Preferred Stock and all such parity stock on which dividends are
         payable or in arrears in proportion to the total amounts to which the
         holders of all such shares are then entitled;

                 (iii)   redeem or purchase or otherwise acquire for
         consideration shares of any stock ranking on a parity (either as to
         dividends or upon liquidation, dissolution or winding up) with the
         Series A Junior Participating Class A Preferred Stock, provided that
         the Company may at any time redeem, purchase or otherwise acquire
         shares of any such parity stock in exchange for shares of any stock of
         the Company ranking junior (either as to dividends or upon
         dissolution,  liquidation or winding up) to the Series A Junior
         Participating Class A Preferred Stock;

                 (iv)   purchase or otherwise acquire for consideration any
         shares of Series A Junior Participating Class A Preferred Stock, or
         any shares of stock ranking on a parity with the Series A Junior
         Participating Class A Preferred Stock, except in accordance with a
         purchase offer made in writing or by publication (as determined by the
         Board of Directors) to all holders of such shares upon such terms as
         the Board of Directors, after consideration of the respective annual
         dividend rates and other relative rights and preferences of the
         respective series and classes, shall determine in good faith will
         result in fair and equitable treatment among the respective series or
         classes.

         (B)   The Company shall not permit any subsidiary of the Company to
purchase or otherwise acquire for consideration any shares of stock of the
Company unless the Company could, under paragraph (A) of this Section 4,
purchase or otherwise acquire such shares at such time and in such manner.





                                       7
<PAGE>   51
         Section 5.   Reacquired Shares.   Any shares of Series A Junior
Participating Class A Preferred Stock purchased or otherwise acquired by the
Company in any manner whatsoever shall be retired and cancelled promptly after
the acquisition thereof.  All such shares shall upon their cancellation become
authorized but unissued shares of Class A Preferred Stock and may be reissued
as part of a new series of Class A Preferred Stock to be created by resolution
or resolutions of the Board of Directors, subject to the conditions and
restrictions on issuance set forth herein.

         Section 6.   Liquidation, Dissolution or Winding Up. (A) Upon any
liquidation (voluntary or otherwise), dissolution or winding up of the Company,
no distribution shall be made to the holders of shares of stock ranking junior
(either as to dividends or upon liquidation, dissolution or winding up) to the
Series A Junior Participating Class A Preferred Stock unless, prior thereto,
the holders of shares of Series A Junior Participating Class A Preferred Stock
shall have received $19,000 per share, plus an amount equal to accrued and
unpaid dividends and distributions thereon, whether or not declared, to the
date of such payment (the "Series A Liquidation Preference"). Following the
payment of the full amount of the Series A Liquidation Preference, no
additional distributions shall be made to the holders of shares of Series A
Junior Participating Class A Preferred Stock unless, prior thereto, the holders
of shares of Common Stock shall have received an amount per share (the "Common
Adjustment") equal to the quotient obtained by dividing (i) the Series A
Liquidation Preference by (ii) 100 (as appropriately adjusted as set forth in
subparagraph C below to reflect such events as stock splits, stock dividends
and recapitalizations with respect to the Common Stock)  (such number in clause
(ii),  the "Adjustment Number"). Following the payment of the full amount of
the Series A Liquidation Preference and the Common Adjustment in respect of all
outstanding shares of Series A Junior Participating Class A Preferred Stock and
Common Stock, respectively, holders of Series A Junior Participating Class A
Preferred Stock and holders of shares of Common Stock shall receive their
ratable and proportionate share of the remaining assets to be distributed in
the ratio of the Adjustment Number to 1 with respect to such Preferred Stock
and Common Stock, on a per share basis, respectively.

         (B)   In the event there are not sufficient assets available to permit
payment in full of the Series A Liquidation Preference and the liquidation
preferences of all other series of preferred stock, if any, which rank on a
parity with the Series A Junior Participating Class A Preferred Stock, then
such remaining assets shall be distributed ratably to the





                                       8
<PAGE>   52
holders of such parity shares in proportion to their respective liquidation
preferences. In the event there are not sufficient assets available to permit
payment in full of the Common Adjustment, then such remaining assets shall be
distributed ratably to the holders of Common Stock.

         (C)   In the event the Company shall at any time after the Rights
Declaration Date (i) declare any dividend on Common Stock payable in shares of
Common Stock,  (ii) subdivide the outstanding Common Stock, or (iii) combine
the outstanding Common Stock into a smaller number of shares, then in each such
case the Adjustment Number in effect immediately prior to such event shall be
adjusted by multiplying such Adjustment Number by a fraction the numerator of
which is the number of shares of Common Stock outstanding immediately after
such event and the denominator of which is the number of shares of Common Stock
that were outstanding immediately prior to such event.

         Section 7.   Consolidation, Merger, etc. In case the Company shall
enter into any consolidation, merger, combination or other transaction in which
the shares of Common Stock are exchanged for or changed into other stock or
securities, cash and/or any other property, then in any such case the shares of
Series A Junior Participating Class A Preferred Stock shall at the same time be
similarly exchanged or changed in an amount per share (subject to the provision
for adjustment hereinafter set forth) equal to 100 times the aggregate amount
of stock, securities, cash and/or any other property (payable in kind), as the
case may be, into which or for which each share of Common Stock is changed or
exchanged. In the event the Company shall at any time after the Rights
Declaration Date (i) declare any dividend on Common Stock payable in shares of
Common Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, then in each such
case the amount set forth in the preceding sentence with respect to the
exchange or change of shares of Series A Junior Participating Class A Preferred
Stock shall be adjusted by multiplying such amount by a fraction the numerator
of which is the number of shares of Common Stock outstanding immediately after
such event and the denominator of which is the number of shares of Common Stock

                        (PURSUANT TO SECTION 151 OF THE
               GENERAL CORPORATION LAW OF THE STATE OF DELAWARE)

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

BURLINGTON NORTHERN INC., a corporation organized and existing under the
General Corporation Law of the State of Delaware (the "Corporation"), hereby
certifies that the following resolution was adopted by the Finance Committee of
the Board of Directors of the Corporation:

RESOLVED, that pursuant to the authority expressly granted to and vested in the
Board of Directors of the Corporation (the "Board of Directors") by the
provisions of the Certificate of Incorporation of the Corporation (the
"Certificate of Incorporation"), and duly delegated to this Committee of the
Board of Directors pursuant to Section 141(c) of the General Corporation Law of

Directors on July 16, 1992, there hereby is created, out of the 25,000,000
shares of preferred Stock, no par value, of the Corporation authorized in
Article Fourth of the Certificate of Incorporation (the "Preferred Stock"), a
series of the Preferred Stock consisting of 6,900,000 shares, which series

qualifications, limitations, and restrictions, set forth in the Certificate of
Incorporation which are applicable to preferred stock and/or to the Preferred
Stock):

SECTION 1. DESIGNATION OF AMOUNT. The shares of such series shall be designated
as "6 1/4% Cumulative Convertible Preferred Stock, Series A, No Par Value," (the
"6 1/4% Preferred Stock") and the authorized number of shares constituting such
series shall be 6,900,000. The 6 1/4% Preferred Stock shall be no par value
stock.
<PAGE>   67
SECTION 2. DIVIDENDS.

         (a)     The holders of shares of the 6 1/4% Preferred Stock will be
                 entitled to receive when, as, and if declared by the Board of
                 Directors out of funds of the Corporation legally available
                 therefor, cumulative cash dividends on the shares of the 6 1/4%
                 Preferred Stock at the rate of $3.125 per annum per share of
                 6 1/4% Preferred Stock, AND NO MORE, payable in arrears in
                 equal quarterly installments on January 1, April 1, July 1,
                 and October 1 of each year, commencing on January 1, 1993.
                 Such dividends shall be cumulative from the date of original
                 issuance of any shares of the 6 1/4% Preferred Stock. Each such
                 dividend shall be paid to the holders of record of the shares
                 of the 6 1/4% Preferred Stock as they appear on the stock
                 register of the Corporation on such record date, which shall
                 be not more than 30 days nor less than 10 days preceding the
                 dividend payment date thereof, as shall be fixed by the Board
                 of Directors or a duly authorized committee thereof. If a
                 holder converts a share or shares of the 6 1/4% Preferred Stock
                 after the close of business on the record date for a dividend
                 and before the opening of business on the payment date for
                 such dividend (except for a share or shares called for
                 redemption on a Redemption Date (as defined in Section 3(c)
                 hereof) during the period from the close of business on any
                 dividend payment record date to the close of business on the
                 corresponding dividend payment date), then, pursuant to
                 Section 6 hereof, the holder will be required to pay to the
                 Corporation at the time of such conversion the amount of such
                 dividend.

         (b)     If dividends are not paid in full, or declared in full, and
                 sums set apart for the payment thereof, upon the shares of the
                 6 1/4% Preferred Stock and shares of any other preferred stock
                 ranking on a parity as dividends with the 6 1/4% Preferred
                 Stock, all dividends declared upon shares of the 6 1/4%
                 Preferred Stock, and of any other preferred stock ranking on a
                 parity as to dividends, shall be paid or declared pro rata so
                 that in all cases the amount of dividends paid or declared per
                 share on the 6 1/4% Preferred Stock, and such other preferred
                 stock, shall bear to each other the same ratio that
                 accumulated dividends per share, including dividends accrued
                 or in arrears, if any, on the shares of the 6 1/4% Preferred
                 Stock, and such other preferred stock, bear to each other.
                 Except as provided in the preceding sentence, unless full
                 cumulative dividends on the shares of the 6 1/4% Preferred
                 Stock have been paid or declared in full and sums set aside
                 for the payment thereof, no dividends (other than dividends
                 in shares of, or options, warrants, or rights to subscribe for
                 or purchase shares

                 of the Common Stock (as hereinafter defined) or in shares of
                 any other capital stock of the Corporation ranking junior to
                 the 6 1/4% Preferred Stock as to dividends) shall be paid or
                 declared and set aside for payment or other distribution made
                 upon the Corporation's Common Stock, without par value (the
                 "Common Stock"), or, except as provided above, on any other
                 capital stock of the Corporation ranking junior to or on a
                 parity with the 6 1/4% Preferred Stock as to dividends, nor
                 shall any shares of the Common Stock or shares of any other
                 capital stock of the Corporation ranking junior to or on a
                 parity with the 6 1/4% Preferred Stock as to dividends be
                 redeemed, purchased, or otherwise acquired for any
                 consideration (or any payment made to or available for a
                 sinking fund for the redemption of any such shares) by the
                 Corporation or any subsidiary of the Corporation (except by
                 conversion into or exchange for shares of capital stock of the
                 Corporation ranking junior to the 6 1/4% Preferred Stock as to
                 dividends). Holders of shares of the 6 1/4% Preferred Stock
                 shall not be entitled to any dividends, whether payable in
                 cash, property, or shares of capital stock, in excess of full
                 accrued and cumulative dividends as herein provided. No
                 interest or sum of money in lieu of interest shall be payable
                 in respect of any dividend payment or payments on the shares
                 of the 6 1/4% Preferred Stock that may be in arrears.

                 The terms "accrued dividends," "dividends accrued," and
                 "dividends in arrears," whenever used herein with reference to
                 shares of preferred stock shall be deemed to mean an amount
                 which shall be equal to dividends thereon at the annual
                 dividend rates per share for the respective series from the
                 date or dates on which such dividends commence to accrue to
                 the end of the then current quarterly dividend period for such
                 preferred stock (or, in the case of redemption, to the date of
                 redemption), less the amount of all dividends paid, or
                 declared in full and sums set aside for the payment thereof,
                 upon such shares of preferred stock.

         (c)     Dividends payable on the shares of the 6 1/4% Preferred Stock
                 for any period less than a full quarterly dividend period
                 shall be computed on the basis of a 360-day year of twelve
                 30-day months and the actual number of days elapsed in the
                 period for which payable. Any dividend otherwise payable on a
                 date which is not a business day will be paid on the next day
                 which is a business day, but without interest.

                 Corporation to redeem such shares, stating the date fixed for
                 redemption thereof (the "Redemption Date"), and calling upon
                 such holder to surrender to the Corporation, on the Redemption

                 than all the shares represented by any such certificate are
                 redeemed, a new certificate shall be issued representing the

                 From and after the Redemption Date (unless default shall be
                 made by the Corporation in payment of the redemption price),

                 certificates representing the same, shall cease and terminate

                 with the consent of the Corporation) on the books of the
                 Corporation, and such shares shall not be deemed to be
                 outstanding for any purpose whatsoever. At its election, the

                 redemption price (including all accrued and unpaid dividends
                 up to the Redemption Date) of shares of the 6 1/4% Preferred
                 Stock so called for redemption in trust for the holders
                 thereof with a bank or trust company (having a capital surplus
                 and undivided profits aggregating not less than $50,000,000)
                 in the Borough of Manhattan, City and State of New York, or in
                 any other city in which the Corporation at the time shall
                 maintain a transfer agency with respect to such shares, in
                 which case the aforesaid notice to holders of shares of the
                 6 1/4% Preferred Stock to be redeemed shall state the date of
                 such deposit, shall specify the office of such bank or trust
                 company as the place of payment of the redemption price, and
                 shall call upon such holders to surrender the certificates
                 representing such shares at such place on or after the date
                 fixed in such redemption notice (which shall not be later than
                 the Redemption Date) against payment of the redemption price
                 (including all accrued and unpaid dividends up to the
                 Redemption Date). Any interest accrued on such funds shall be
                 paid to the Corporation from time to time. Any moneys so
                 deposited which shall remain unclaimed by the holders of such
                 shares of the 6 1/4% Preferred Stock at the end of two years
                 after the Redemption Date shall be returned by such bank or
                 trust company to the Corporation.

                 If a notice of redemption has been given pursuant to this
                 Section 3 and any holder of shares of the 6 1/4% Preferred
                 Stock shall, prior to the close of business on the last
                 business day preceding the Redemption Date, give written
                 notice to the Corporation pursuant to Section 6 below of the
                 conversion of any or all of the

<PAGE>   71
                 shares to be redeemed held by such holder (accompanied by a
                 certificate or certificates for such shares, duly endorsed or
                 assigned to the Corporation, and any necessary transfer tax
                 payment, as required by Section 6 below), then such redemption
                 shall not become effective as to such shares to be converted,
                 such conversion shall become effective as provided in Section
                 6 below, and any moneys set aside by the Corporation for the
                 redemption of such shares of converted 6 1/4% Preferred Stock
                 shall revert to the general funds of the Corporation.

         (d)     Shares of the 6 1/4% Preferred Stock redeemed, repurchased,
                 retired, or otherwise acquired by the Corporation (whether
                 pursuant to the provisions of Section 3 or otherwise), or
                 surrendered to the Corporation upon conversion, or which were
                 not originally issued as part of a contemplated public
                 offering of such 6 1/4% Preferred Stock, shall cease to be
                 shares of the 6 1/4% Preferred Stock and shall thereupon be
                 retired and may not be reissued as shares of the 6 1/4%
                 Preferred Stock, but shall thereafter have the status of
                 authorized but unissued shares of the Preferred Stock, without
                 designation as to series, until such shares are once more
                 designated as part of a particular series of the Preferred
                 Stock by the Board of Directors.

SECTION 4. VOTING RIGHTS.

         (a)     Except as otherwise set forth hereafter, or by the laws of
                 the State of Delaware specifically provided, the holders of
                 shares of the 6 1/4% Preferred Stock shall not be entitled to
                 vote on any question or matter, or in any proceedings, or to
                 be represented at or to receive notice of any meeting of
                 stockholders of the Corporation; provided, however, that the
                 holders of the 6 1/4% Preferred Stock will have voting rights
                 as provided in this Section 4 and in Section 8 hereof. When
                 the holders of the 6 1/4% Preferred Stock vote on any matter as
                 members of a class which does not include the holders of
                 Common Stock, the holders of 6 1/4% Preferred Stock shall be
                 entitled to an aggregate number of votes which is in the same
                 proportion to the total number of class votes as the aggregate
                 liquidation preference of the outstanding shares of 6 1/4%
                 Preferred Stock bears to the aggregate liquidation preference
                 of all shares of capital stock in the class; and each holder
                 of 6 1/4% Preferred Stock shall be entitled to his or her
                 proportionate share of the aggregate number of votes to which
                 the holders of 6 1/4% Preferred Stock are entitled.

         (b)     In the event that the Corporation shall have failed to declare
                 and pay or set apart for payment in full the dividends
                 accumulated on the outstanding shares of the 6 1/4% Preferred 
                 Stock for any six quarterly dividend payment periods, whether 
                 or not consecutive (a "Preferential Dividend Non-Payment"), the
                 number of directors of the Corporation shall be increased by
                 two and the holders of outstanding shares of the 6 1/4% 
                 Preferred Stock, voting together as a class with all other 
                 series of Preferred Stock of the Corporation ranking on a 
                 parity with the 6 1/4% Preferred Stock with respect to 
                 dividends or distribution of assets upon liquidation and then 
                 entitled to vote on the election of such additional directors,
                 shall be entitled to elect, as a single class separately from 
                 the holders of any other class of capital stock of the
                 Corporation, two additional directors until the full dividends
                 accumulated on all outstanding shares of the 6 1/4% Preferred
                 Stock have been declared and paid or set apart for payment.
                 Upon the occurrence of a Preferential Dividend Non-Payment,
                 the Board of Directors shall, within a reasonable period, call
                 a special meeting of the holders of shares of the 6 1/4%
                 Preferred Stock and all holders of other classes or series of
                 preferred stock of the Corporation ranking on a parity with
                 the 6 1/4% Preferred Stock with respect to the payment of
                 dividends or distribution of assets upon liquidation who are
                 then entitled to vote on the election of such additional
                 directors for the purpose of electing the additional directors
                 provided by the foregoing provisions. If and when all
                 accumulated dividends on the shares of the 6 1/4% Preferred
                 Stock have been declared and paid or set aside for payment in
                 full, the holders of shares of the 6 1/4% Preferred Stock shall
                 be divested of the special voting rights provided by this
                 Section 4(b), subject to revesting in the event of each and
                 every subsequent Preferential Dividend Non-Payment. Upon
                 termination of such special voting rights attributable to all
                 holders of shares of the 6 1/4% Preferred Stock and shares of
                 any other class or series of preferred stock of the
                 Corporation ranking on a parity with the 6 1/4% Preferred Stock
                 with respect to payment of dividends or distribution of assets
                 upon liquidation, the term of office of each Director elected
                 by the holders of shares of the 6 1/4% Preferred Stock and such
                 parity Preferred Stock (a "Preferred Stock Director") pursuant
                 to such special voting rights shall forthwith terminate and
                 the number of directors constituting the entire Board of
                 Directors shall be reduced by the number of Preferred Stock
                 Directors. Any Preferred Stock Director may be removed by, and
                 shall not be removed otherwise than by, the vote of the
                 holders of record of a majority of the outstanding shares of
                 the 6 1/4% Preferred Stock and





                                      -7-
<PAGE>   73
                 all other series of Preferred Stock ranking on a parity with
                 the 6 1/4% Preferred Stock with respect to the payment of
                 dividends or distribution of assets upon liquidation who were
                 entitled to vote in such Preferred Stock Director's election,
                 voting as a separate class, at a meeting called for such
                 purpose.

         (c)     So long as any shares of this Series are outstanding, the
                 bylaws of the Corporation shall contain provisions ensuring
                 that the number of Directors constituting the entire Board of
                 Directors of the Corporation shall at all times be such that
                 the exercise, by the holders of shares of the 6 1/4% Preferred
                 Stock and the holders of parity Preferred Stock, of the right
                 to elect Directors under the circumstances provided for in
                 subclause (a) of this Section 4 will not contravene any
                 provision of this Certificate of Incorporation restricting the
                 number of Directors which may constitute the entire Board of
                 Directors of the Corporation.

         (d)     Directors elected pursuant to subclause (b) of this Section 4
                 shall serve until the earlier of (1) the next annual meeting
                 of the stockholders of the Corporation and the election (by
                 the holders of shares of the 6 1/4% Preferred Stock and the
                 holders of parity Preferred Stock) and qualification of their
                 respective successors, or (2) the date upon which all
                 dividends in default on the shares of the 6 1/4% Preferred
                 Stock and such other parity Preferred Stock shall have been
                 paid in full.

         (e)     So long as a Preferential Dividend Non-Payment shall continue,
                 any vacancy in the office of a Preferred Stock Director may be
                 filled by written consent of the Preferred Stock Director
                 remaining in office or, if none remain in office, by vote of
                 the holders of record of a majority of the outstanding shares
                 of the 6 1/4% Preferred Stock and all other series of Preferred
                 Stock ranking on a parity with the 6 1/4% Preferred Stock with
                 respect to the payment of dividends or distribution of assets
                 upon liquidation who are then entitled to vote in the election
                 of such Preferred Stock Directors as provided above. As long
                 as the preferential Dividend Non-Payment shall continue,
                 holders of shares of the 6 1/4% Preferred Stock shall not, as
                 such stockholders, be entitled to vote on the election or
                 removal of directors other than Preferred Stock Directors, but
                 shall not be divested of any other voting rights provided to
                 such stockholders by law with respect to any other matter to
                 be acted upon by the stockholders of the Corporation.

SECTION 5. LIQUIDATION RIGHTS

         (a)     In the event of any liquidation, dissolution, or winding up of
                 the affairs of the Corporation, whether voluntary or
                 otherwise, after payment or provision for payment of the
                 debts and other liabilities of the Corporation, the holders of
                 shares of the 6 1/4% Preferred Stock shall be entitled to
                 receive, in cash, out of the remaining net assets of the
                 Corporation, the amount of Fifty Dollars ($50.00) for each
                 share of the 6 1/4% Preferred Stock, plus an amount equal to
                 all dividends accrued and unpaid on each such share up the
                 date fixed for distribution, AND NO MORE, before any
                 distribution shall be made to the holders of shares of the
                 Common Stock or any other capital stock of the Corporation
                 ranking (as to any such distribution) junior to the 6 1/4%
                 Preferred Stock. If, upon any liquidation, dissolution, or
                 winding up of the Corporation, the assets distributable among
                 the holders of shares of the 6 1/4% Preferred Stock and all
                 other classes and series of preferred stock ranking (as to any
                 such distribution) on a parity with the 6 1/4% Preferred Stock
                 are insufficient to permit the payment in full to the holders
                 of all such shares of all preferential amounts payable to all
                 such holders, then the entire assets of the Corporation thus
                 distributable shall be distributed ratably among the holders
                 of the shares of the 6 1/4% Preferred Stock and any such other
                 classes and series of preferred stock ranking (as to any such
                 distribution) on a parity with the 6 1/4% Preferred Stock in
                 proportion to the respective amounts that would be payable per
                 share if such assets were sufficient to permit payment in
                 full.


         (b)     For purposes of this Section 5, a distribution of assets in
                 any dissolution, winding up, or liquidation shall not include
                 (i) any consolidation or merger of the Corporation with or
                 into any other corporation or (ii) a sale or other disposition
                 of all or substantially all of the Corporation's assets to
                 another corporation.

         (c)     After the payment of the full preferential amounts provided
                 for herein to the holders of shares of the 6 1/4% Preferred
                 Stock or funds necessary for such payment have been set aside
                 in trust for the holders thereof, such holders shall be
                 entitled to no other or further participation in the
                 distribution of the assets of the Corporation.

SECTION 6. CONVERSION

         (a)     Holders of shares of the 61/4% Preferred Stock shall have the
                 right, exercisable at any time and from time





                                      -9-
<PAGE>   75
                 to time, except in the case of shares of the 6 1/4% Preferred
                 Stock called for redemption, to convert all or any such shares
                 of the 6 1/4% Preferred Stock into such number of whole shares
                 of the Common Stock as is equal to the aggregate liquidation
                 preference amount of the shares of 6 1/4% Preferred Stock
                 surrendered for conversion divided by the conversion price of
                 $47 per share of such Common Stock (equivalent to a conversion
                 rate of 1.0638298 shares of the Common Stock for each share of
                 the 6 1/4% Preferred Stock so converted), subject to adjustment
                 as described below. In the case of shares of the 6 1/4%
                 Preferred Stock called for redemption, conversion rights will
                 expire at the close of business on the day preceding the date
                 fixed for redemption. Notice of an optional redemption must be
                 mailed not less than 30 days and not more than 60 days prior
                 to the Redemption Date. Upon conversion, no adjustment or
                 payment will be made on account of accrued or unpaid
                 dividends, but if any holder surrenders a share of the 6 1/4%
                 Preferred Stock for conversion after the close of business on
                 the record date for the payment of a dividend and prior to the
                 opening of business on the next dividend payment date, then,
                 notwithstanding such conversion, the dividend payable on such
                 dividend payment date will be paid to the registered holder of
                 such share of the 6 1/4% Preferred Stock on such record date.
                 In such event, such share of the 6 1/4% Preferred Stock, when
                 surrendered for conversion during the period between the close
                 of business on any dividend payment record date and the
                 opening of business on the corresponding dividend payment date
                 (except for a share or shares of the 6 1/4% Preferred Stock
                 called for redemption on a Redemption Date (as defined in
                 Section 3(c) hereof) during the period from the close of
                 business on any dividend payment record date to the close of
                 business on the corresponding dividend payment date), must be
                 accompanied by payment of an amount equal to the dividend
                 payable on such dividend payment date on the share so
                 converted. A holder of shares of the 6 1/4% Preferred Stock on
                 a dividend payment record date who (or whose transferee)
                 converts such shares of 6 1/4% Preferred Stock on a dividend
                 payment date will receive the dividend payable on such shares
                 of 6 1/4% Preferred Stock by the Corporation on such dividend
                 payment date, and the converting holder need not include
                 payment in the amount of such dividend upon surrender of
                 shares of the 6 1/4% Preferred Stock for conversion on such
                 dividend payment date.

         (b)     Any holder of a share or shares of the 6 1/4% Preferred Stock
                 electing to convert such share or shares thereof shall deliver
                 the certificate or certificates therefor to the principal
                 office of any transfer agent for the





                                      -10-
<PAGE>   76
                 Common Stock, with the form of notice of election to convert
                 as the Corporation shall prescribe fully completed and duly
                 executed and (if so required by the Corporation or any
                 conversion agent) accompanied by instruments of transfer in
                 form satisfactory to the Corporation and to any conversion
                 agent, duly executed by the registered holder or his duly
                 authorized attorney, and transfer taxes, stamps or funds
                 therefor or evidence of payment thereof if required pursuant
                 to Section 6(a) or 6(d) hereof. The conversion right with
                 respect to any such shares shall be deemed to have been
                 exercised at the date upon which the certificates therefor
                 accompanied by such duly executed notice of election and
                 instruments of transfer and such taxes, stamps, funds or
                 evidence of payment shall have been so delivered, and the
                 person or persons entitled to receive the shares of the Common
                 Stock issuable upon such conversion shall be treated for all
                 purposes as the record holder or holders of such shares of the
                 Common Stock upon said date.

         (c)     No fractional shares of the Common Stock or scrip representing
                 fractional shares shall be issued upon conversion of shares of
                 the 6 1/4% Preferred Stock. If more than one share of the 
                 6 1/4% Preferred Stock shall be surrendered for conversion at
                 one time by the same holder, the number of full shares of the
                 Common Stock which shall be issuable upon conversion thereof
                 shall be computed on the basis of the aggregate number of
                 shares of the 6 1/4% Preferred Stock so surrendered. Instead of
                 any fractional shares of the Common Stock which would
                 otherwise be issuable upon conversion of any shares of the
                 6 1/4% Preferred Stock, the Corporation shall pay a cash
                 adjustment in respect of such fraction in an amount equal to
                 the same fraction of the closing price for the Common Stock on
                 the last trading day preceding the date of conversion. The
                 closing price for such day shall be the last reported sales
                 price regular way or, in case no such reported sale takes
                 place on such date, the average of the reported closing bid
                 and asked prices regular way, in either case on the New York
                 Stock Exchange, or if the Common Stock is not listed or
                 admitted to trading on such Exchange, on the principal
                 national securities exchange on which the Common Stock is
                 listed or admitted to trading or, if not listed or admitted to
                 trading on any national securities exchange, the closing sale
                 price of the Common Stock or in case no reported sale takes
                 place, the average of the closing bid and asked prices, on
                 NASDAQ or any comparable system. If the Common Stock is not
                 quoted on NASDAQ or any comparable system, the Board of
                 Directors shall in good faith determine the current market
                 price on the basis of such quotation as it considers
                 appropriate.

         (d)     If a holder converts a share or shares of the 6 1/4% Preferred
                 Stock, the Corporation shall pay any documentary, stamp or
                 similar issue or transfer tax due on the issue of Common Stock
                 upon the conversion. The holder, however, shall pay to the
                 Corporation the amount of any tax which is due (or shall
                 establish to the satisfaction of the Corporation payment
                 thereof) if the shares are to be issued in a name other than
                 the name of such holder and shall pay to the Corporation any
                 amount required by the last sentence of Section 6(a) hereof.

         (e)     The Corporation shall reserve and shall at all times have
                 reserved out of its authorized but unissued shares of the
                 Common Stock enough shares of the Common Stock to permit the
                 conversion of the then outstanding shares of the 6 1/4%
                 Preferred Stock.  All shares of Common Stock which may be
                 issued upon conversion of shares of the 6 1/4% Preferred Stock
                 shall be validly issued, fully paid and nonassessable. In
                 order that the Corporation may issue shares of the Common
                 Stock upon conversion of shares of the 6 1/4% Preferred Stock,
                 the Corporation will endeavor to comply with all applicable
                 Federal and State securities laws and will endeavor to list
                 such shares of the Common Stock to be issued upon conversion
                 on each securities exchange on which the Common Stock is
                 listed.

         (f)     The conversion price in effect at any time shall be subject to
                 adjustment from time to time as follows:

                 (i)      In case the Corporation shall (1) pay a dividend or
                          make a distribution in shares of the Common Stock to
                          holders of any class of capital stock of the
                          Corporation, (2) subdivide or reclassify the
                          outstanding shares of the Common Stock into a greater
                          number of shares of the Common Stock or (3) combine
                          the outstanding shares of the Common Stock into a
                          smaller number of shares of the Common Stock, the
                          conversion price immediately prior to such action
                          shall be adjusted so that the holder of any shares of
                          the 6 1/4% Preferred Stock thereafter surrendered for
                          conversion shall be entitled to receive the number of
                          shares of the Common Stock which he would have owned
                          immediately following such action had such shares of
                          the 6 1/4% Preferred Stock been converted immediately
                          prior thereto. An adjustment made pursuant to this
                          Section 6(f)(i) shall become effective immediately
                          after the record date in the case of a dividend or
                          distribution and shall become effective immediately
                          after the effective date in the case of a subdivision
                          or combination.

                 (ii)     In case the Corporation shall issue rights or
                          warrants to all holders of the Common Stock (other
                          than those rights to purchase shares of Series A
                          Junior Participating Class A Preferred Stock,
                          declared and distributed on July 10, 1986, to holders
                          of the Common Stock, which became exercisable if a
                          person or group acquires securities representing 20
                          percent or more of the Corporation's voting
                          securities or announces a tender offer which would
                          result in such ownership without the prior consent of
                          the Corporation or any similar rights issued under
                          any successor shareholder rights plan) entitling them
                          to subscribe for or purchase shares of the Common
                          Stock (or securities convertible into shares of the
                          Common Stock) at a price per share less than the
                          current market price (as determined pursuant to
                          Section 6(f)(iv)) of the Common Stock on such record
                          date, the number of shares of the Common Stock into
                          which each share of the 6 1/4% Preferred Stock shall
                          be convertible shall be adjusted so that the same
                          shall be equal to the number determined by
                          multiplying the number of shares of the Common Stock
                          into which such share of the 6 1/4% Preferred Stock
                          was convertible immediately prior to such record date
                          by a fraction of which the numerator shall be the
                          number of shares of the Common Stock outstanding on
                          such record date plus the number of additional shares
                          of the Common Stock offered (or into which the
                          convertible securities so offered are convertible),
                          and of which the denominator shall be the number of
                          shares of the Common Stock outstanding on such record
                          date, plus the number of shares of the Common Stock
                          which the aggregate offering price of the offered
                          shares of the Common Stock (or the aggregate
                          conversion price of the convertible securities so
                          offered) would purchase at such current market price.
                          Such adjustments shall become effective immediately
                          after such record date.

                 (iii)    In case the Corporation shall distribute to all
                          holders of the Common Stock evidences of indebtedness
                          or other assets, including securities, but excluding
                          those dividends, rights, warrants, and distributions
                          referred to in Section 6(f)(i) and (ii), and
                          dividends and distributions paid in cash out of
                          profits or surplus, or shall distribute to all
                          holders of the Common Stock rights or warrants to
                          subscribe for securities (other than those referred
                          to in Section 6(f)(ii), then, in each such case, the
                          number of shares of the Common Stock into which each
                          share of the 6 1/4%

                          Preferred Stock shall be convertible shall be
                          adjusted so that the same shall equal the number
                          determined by multiplying the number of shares of the
                          Common Stock into which such share of the 6 1/4%
                          Preferred Stock was convertible immediately prior to
                          the date of such distribution by a fraction of which
                          the numerator shall be the current market price
                          (determined as provided in Section 6(f)(iv) of the
                          Common Stock on the record date mentioned below, and
                          of which the denominator shall be such current market
                          price of the Common Stock, less the then fair market
                          value (as determined by the Board of Directors, whose
                          determination shall be conclusive evidence of such
                          fair market value) of the portion of the assets so
                          distributed or of such subscription rights or
                          warrants applicable to one share of the Common 
                          Stock. Such adjustment shall become effective 
                          immediately after the record date  for the 
                          determination of the holders of the Common Stock 
                          entitled to receive such distribution.
                           Notwithstanding the foregoing, in the event that the
                          Corporation shall distribute rights or warrants
                          (other than those referred to in Section 6(f)(ii))
                          ("Rights") pro rata to holders of the Common Stock,
                          the Corporation may, in lieu of making any adjustment
                          pursuant to this Section 6(f)(iii), make proper
                          provision so that each holder of a share of the 6 1/4%
                          Preferred Stock who converts such share after the
                          record date for such distribution and prior to the
                          expiration or redemption of the Rights shall be
                          entitled to receive upon such conversion, in addition
                          to the shares of the Common Stock issuable upon such
                          conversion (the "Conversion Shares"), a number of
                          Rights to be determined as follows: (i) if such
                          conversion occurs on or prior to the date for the
                          distribution to the holders of Rights of separate
                          certificates evidencing such Rights (the
                          "Distribution Date"), the same number of Rights to
                          which a holder of a number of shares of the Common
                          Stock equal to the number of Conversion Shares is
                          entitled at the time of such conversion in accordance
                          with the terms and provisions of and applicable to
                          the Rights; and (ii) if such conversion occurs after
                          the Distribution Date, the same number of Rights to
                          which a holder of the number of the Common Stock into
                          which a share of the 6 1/4% Preferred Stock so
                          converted was convertible immediately prior to the
                          Distribution Date would have been entitled on the
                          Distribution Date in accordance with the terms and
                          provisions of and applicable to the Rights.

                 (iv)     The current market price per share of the Common
                          Stock on any date shall be deemed to be the average
                          of the daily closing prices for thirty consecutive
                          trading days commencing forty-five trading days
                          before the day in question. The closing price for
                          each day shall be the last reported sales price
                          regular way or, in case no such reported sale takes
                          place on such date, the average of the reported
                          closing bid and asked prices regular way, in either
                          case on the New York Stock Exchange, or if the Common
                          Stock is not listed or admitted to trading on such
                          Exchange, on the principal national securities
                          exchange on which the Common Stock is listed or
                          admitted to trading or, if not listed or admitted to
                          trading on any national securities exchange, the
                          closing sale price of the Common Stock, or in case no
                          reported sale takes place the average of the closing
                          bid and asked prices, on NASDAQ or any comparable
                          system, or if the Common Stock is not quoted on
                          NASDAQ or any comparable system, the closing sale
                          price or, in case no reported sale takes place, the
                          average of the closing bid and asked prices, as
                          furnished by any two members of the National
                          Association of Securities Dealers, Inc. selected from
                          time to time by the Corporation for that purpose.

                 (v)      In any case in which this Section 6 shall require
                          that an adjustment be made immediately following a
                          record date, the Corporation may elect to defer (but
                          only until five business days following the mailing
                          of the notice described in Section 6(j)) issuing to
                          the holder of any share of the 6 1/4% Preferred Stock
                          converted after such record date the shares of the
                          Common Stock and other capital stock of the
                          Corporation issuable upon such conversion over and
                          above the shares of the Common Stock and other
                          capital stock of the Corporation issuable upon such
                          conversion only on the basis of the conversion price
                          prior to adjustment; and, in lieu of the shares the
                          issuance of which is so deferred, the Corporation
                          shall issue or cause its transfer agents to issue due
                          bills or other appropriate evidence of the right to
                          receive such shares.

         (g)     No adjustment in the conversion price shall be required until
                 cumulative adjustments result in a concomitant change of 1% or
                 more of the conversion price as existed prior to the last
                 adjustment of the conversion price; provided, however, that
                 any adjustments which by reason of this Section 6(g) are not
                 required to be made shall be carried forward and taken into
                 account in any subse-

                 quent adjustment. All calculations under this Section 6 shall
                 be made to the nearest cent or to the nearest one-hundredth of
                 a share, as the case may be. No adjustment to the conversion
                 price shall be made for cash dividends.

         (h)     In the event that, as a result of an adjustment made pursuant
                 to Section 6(f), the holder of any share of the 6 1/4%
                 Preferred Stock thereafter surrendered for conversion shall
                 become entitled to receive any shares of capital stock of the
                 Corporation other than shares of the Common Stock, thereafter
                 the number of such other shares so receivable upon conversion
                 of any shares of the 6 1/4% Preferred Stock shall be subject to
                 adjustment from time to time in a manner and on terms as
                 nearly equivalent as practicable to the provisions with
                 respect to the Common Stock contained in this Section 6.

         (i)     The Corporation may make such decreases in the conversion
                 price, in addition to those required by Sections 6(f)(i), (ii)
                 and (iii), as it considers to be advisable in order that any
                 event treated for Federal income tax purposes as a dividend of
                 stock or stock rights shall not be taxable to the holders of
                 the Common Stock.

         (j)     Whenever the conversion price is adjusted, the Corporation
                 shall promptly mail to all holders of record of shares of the
                 6 1/4% Preferred Stock a notice of the adjustment and shall
                 cause to be prepared a certificate signed by a principal
                 financial officer of the corporation setting forth the
                 adjusted conversion price and a brief statement of the facts
                 requiring such adjustment and the computation thereof; such
                 certificate shall forthwith be filed with each transfer agent
                 for the shares of the 6 1/4% Preferred Stock.

         (k)     In the event that:

                 (1)      the Corporation takes any action which would require
                          an adjustment in the conversion price,

                 (2)      the Corporation consolidates or merges with, or
                          transfers all or substantially all of its assets to,
                          another corporation and stockholders of the
                          Corporation must approve the transaction, or

                 (3)      there is a dissolution or liquidation of the
                          Corporation,

                 a holder of shares of the 6 1/4% Preferred Stock may wish to
                 convert some or all of such shares into shares of the Common
                 Stock prior to the record date for, or





                                      -16-

                 the effective date of, the transaction so that he may receive
                 the rights, warrants, securities or assets which a holder of
                 shares of the Common Stock on that date may receive.
                 Therefore, the Corporation shall mail to holders of shares of
                 the 6 1/4% Preferred Stock a notice stating the proposed record
                 or effective date of the transaction, as the case may be. The
                 Corporation shall mail the notice at least 10 days before such
                 date; however, failure to mail such notice or any defect
                 therein shall not affect the validity of any transaction
                 referred to in clause (1), (2) or (3) of this Section 6(k).

         (1)     If any of the following shall occur, namely: (i) any
                 reclassification or change of outstanding shares of the Common
                 Stock issuable upon conversion of shares of the 6 1/4%
                 Preferred Stock (other than a change in par value, or as a
                 result of a subdivision or combination), (ii) any
                 consolidation or merger to which the Corporation is a party
                 other than a merger in which the Corporation is the continuing
                 corporation and which does not result in any reclassification
                 of, or change (other than a change in name, or par value, or
                 from par value to no par value, or from no par value to par
                 value, or as a result of a subdivision or combination) in,
                 outstanding shares of the Common Stock or (iii) any sale or
                 conveyance of all or substantially all of the property or
                 business of the Corporation as an entirety, then the
                 Corporation, or such successor or purchasing corporation, as
                 the case may be, shall, as a condition precedent to such
                 reclassification, change, consolidation, merger, sale or
                 conveyance, provide in its certificate of incorporation or
                 other charter document that each share of the 6 1/4% Preferred
                 Stock shall be convertible into the kind and amount of shares
                 of capital stock and other securities and property (including
                 cash) receivable upon such reclassification, change,
                 consolidation, merger, sale or conveyance by a holder of the
                 number of shares of the Common Stock deliverable upon
                 conversion of such share of the 6 1/4% Preferred Stock
                 immediately prior to such reclassification, change,
                 consolidation, merger, sale or conveyance. Such certificate of
                 incorporation or other charter document shall provide for
                 adjustments which shall be as nearly equivalent as may be
                 practicable to the adjustments provided for in this Section 6.
                 The foregoing, however, shall not in any way affect the right
                 a holder of a share of the 6 1/4% Preferred Stock may otherwise
                 have, pursuant to clause (ii) of the last sentence of Section
                 6(f)(iii), to receive Rights upon conversion of a share of the
                 6 1/4% Preferred Stock. If, in the case of any such
                 consolidation, merger, sale or conveyance, the stock or other
                 securities and property (including cash) receivable thereupon
                 by a

<PAGE>   83
                 holder of the Common Stock includes shares of capital stock or
                 other securities and property of a corporation other than the
                 successor or purchasing corporation, as the case may be, in
                 such consolidation, merger, sale or conveyance, then the
                 certificate of incorporation or other charter document of such
                 other corporation shall contain such additional provisions to
                 protect the interests of the holders of shares of the 6 1/4%
                 Preferred Stock as the Board of Directors shall reasonably
                 consider necessary by reason of the foregoing. The provision
                 of this Section 6(1) shall similarly apply to successive
                 consolidations, mergers, sales or conveyances.

SECTION 7. RANKING.  With regard to rights to receive dividends or
distributions upon liquidation of the Corporation, the 6 1/4% Preferred Stock
shall rank prior to the Common Stock and on a parity with any other Preferred
Stock or the $10 par value Preferred Stock issued by the Corporation, unless
the terms of such other Preferred Stock provide otherwise and, if applicable,
the requirements of Section 8 hereof have been complied with.

SECTION 8. LIMITATIONS. In addition to any other rights provided by applicable
law, so long as any shares of the 6 1/4% Preferred Stock are outstanding, the
Corporation shall not, without the affirmative vote, or the written consent as
provided by law, of the holders of at least two-thirds (2/3) of the outstanding
shares of the 6 1/4% Preferred Stock, voting as a single class:

         (a)     create, authorize, or issue any class or series of, or rights
                 to subscribe to or any security convertible into, capital
                 stock ranking senior to the 6 1/4% Preferred Stock as to
                 payment of dividends, in distribution of assets upon
                 liquidation or in voting rights; or

         (b)     amend, alter or appeal, whether by merger, consolidation or
                 otherwise, any of the provisions of the Certificate of
                 Incorporation (including this Certificate of Designation) that
                 would change the preferences, rights or powers with respect to
                 the 6 1/4% Preferred Stock so as to affect the 6 1/4% Preferred
                 Stock adversely;

but (except as otherwise required by applicable law) nothing herein contained
shall require such a vote or consent (i) in connection with any increase in the
total number of authorized shares of the Common Stock, or (ii) in connection
with the authorization or increase of any class or series of shares ranking, as
to dividends and distribution of assets upon liquidation, pari passu with or
junior to the 6 1/4% Preferred Stock; provided, however, that no such vote or
written consent of the holders of the shares of the 6 1/4% Preferred Stock shall
be required if, at or prior to the time when the issuance of any such shares
ranking

convertible into or carrying a right to subscribe to or acquire shares of
capital stock of the Corporation.

IN WITNESS WHEREOF, the Corporation has caused this Certificate of Designation
to be signed by David C. Anderson, its Executive Vice President - Chief
Financial Officer, and attested by Edmund W. Burke, Esq., its Executive Vice
President, Law and Secretary, this 24th day of November 1992.

                                INDEMNIFICATION
 
    SECTION 1. Right to Indemnification.
 
     Each person who was or is made a party or is threatened to be made a party
to or is involved (including, without limitation, as a witness) in any actual or
threatened action, suit or proceeding, whether civil, criminal, administrative
or investigative (hereinafter a "proceeding"), by reason of the fact that he or
she is or was a director or officer of the Corporation or is or was serving at
the request of the Corporation as a director, officer, employee or agent of
another corporation or of a partnership, joint venture, trust or other
enterprise, including service with respect to an employee benefit plan
(hereinafter an "indemnitee"), whether the basis of such proceeding is alleged
action in an official capacity as a director, officer, employee or agent or in
any other capacity while serving as a director, officer, employee or agent,
shall be indemnified and held harmless by the Corporation to the full extent
authorized by the Delaware General Corporation Law, as the same exists or may
hereafter be amended (but, in the case of any such amendment, only to the extent
that such amendment permits the Corporation to provide broader indemnification
rights than said law permitted the Corporation to provide prior to such
amendment), or by other applicable law as then in effect, against all expense,
liability and loss (including attorney's fees, judgments, fines, ERISA excise
taxes or penalties and amounts to be paid in settlement) actually and reasonably
incurred or suffered by such indemnitee in connection therewith and such
indemnification shall continue as to an indemnitee who has ceased to be a
director, officer, employee or agent and shall inure to the benefit of the
indemnitee's heirs, executors and administrators, provided, however, that except
as provided in Section 2 of this Article with respect to proceedings seeking to
enforce rights to indemnification, the Corporation shall indemnify any such
indemnitee seeking indemnification in connection with a proceeding (or part
thereof) initiated by such indemnitee only if such proceeding (or part thereof)
was authorized by the Board of Directors of the Corporation. The right to
indemnification conferred in this Section shall be a contract right and shall
include the right to be paid by the Corporation the expenses incurred in
defending any such proceeding in advance of its final disposition (hereinafter
an "advancement of expenses"); provided, however, that, if the Delaware General
Corporation Law requires, an advancement of expenses incurred by an indemnitee
in his or her capacity as a director or officer (and not in any other capacity
in which service was or is rendered by such indemnitee while a director or
officer, including, without limitation, service to an employee benefit plan)
shall be made only upon delivery to the Corporation of an undertaking, by or on
behalf of such indemnitee, to repay all amounts so advanced if it shall
ultimately be determined that such indemnitee is not entitled to be indemnified
under this Section 1, or otherwise.
 
    SECTION 2. Right of Indemnitee to Bring Suit.
 
     If a claim under Section 1 of this Article is not paid in full by the
Corporation within sixty days after a written claim has been received by the
Corporation, except in the case of a claim for an advancement of expenses, in
which case the applicable period shall be twenty days, the indemnitee may at any
time thereafter bring suit against the Corporation to recover the unpaid amount
of the claim and, to the extent successful in whole or in part, the indemnitee
shall be entitled to be paid also the expense of prosecuting such suit. The
indemnitee shall be presumed to be entitled to indemnification under this
Article upon submission of a written claim (and, in an action brought to enforce
a claim for an advancement of expenses where the required undertaking, if any is
required, has been tendered to the Corporation), and thereafter the Corporation
shall have the burden of proof to overcome the presumption that the indemnitee
is not so entitled. Neither the failure of the Corporation (including its Board
of Directors, independent legal counsel or its stockholders) to have made a
determination prior to the commencement of such suit that indemnification of the
indemnitee is proper in the circumstances not an actual determination by the
Corporation (including its Board of Directors, independent legal counsel or its
stockholders) that the indemnitee is not entitled to indemnification shall be a
defense to the suit or create a presumption that the indemnitee is not so
entitled.

<PAGE>   16
 
    SECTION 3. Nonexclusivity of Rights.
 
     The rights to indemnification and to the advancement of expenses conferred
in this Article shall not be exclusive of any other right which any person may
have or hereafter acquire under any statute, provision of the Certificate of
Incorporation, By-Laws, agreement, vote of stockholders or disinterested
directors or otherwise.
 
    SECTION 4. Insurance, Contracts and Funding.
 
     The Corporation may maintain insurance, at its expense, to protect itself
and any director, officer, employee or agent of the Corporation or another
corporation, partnership, joint venture, trust or other enterprise against any
expense, liability or loss, whether or not the Corporation would have the power
to indemnify such person against such expense, liability or loss under the
Delaware General Corporation Law. The Corporation may enter into contracts with
any indemnitee in furtherance of the provisions of this Article and may create a
trust fund, grant a security interest or use other means (including, without
limitation, a letter of credit) to ensure the payment of such amounts as may be
necessary to effect indemnification as provided in this Article.
 
    SECTION 5. Definition of Director and Officer.
 
     Any person who is or was serving as a director of a wholly owned subsidiary
of the Corporation shall be deemed, for purposes of this Article only, to be a
director or officer of the Corporation entitled to indemnification under this
Article.
 
    SECTION 6. Indemnification of Employees and Agents of the Corporation.
 
     The Corporation may, by action of its Board of Directors from time to time,
grant rights to indemnification and advancement of expenses to employees and
agents of the Corporation with the same scope and effects as the provisions of
this Article with respect to the indemnification and advancement of expenses of
directors and officers of the Corporation.
 
                                   ARTICLE XI
 
                      CHECKS, DRAFTS, BANK ACCOUNTS, ETC.
 
     SECTION 1. Checks, Drafts, Etc.; Loans.
 
     All checks, drafts or other orders for the payment of money, notes or other
evidences of indebtedness issued in the name of the Corporation shall be signed
by such officer or officers, agent or agents of the corporation and in such
manner as shall, from time to time, be determined by resolution of the Board of
Directors. No loans shall be contracted on behalf of the corporation unless
authorized by the Board of Directors. Such authority may be general or confined
to specific circumstances.
 
     SECTION 2. Deposits.
 
     All funds of the Corporation shall be deposited, from time to time, to the
Credit of the Corporation in such banks, trust companies or other depositories
as the Board of Directors may select, or as may be selected by any officer or
officers, agent or agents of the corporation to whom such power may, from time
to time, be delegated by the Board of Directors; and for the purpose of such
deposit, the Chairman, the President, any Vice President, the Treasurer or any
Assistant Treasurer, the Secretary or any Assistant Secretary or any other
officer or agent to whom such power may be delegated by the Board of Directors,
may endorse, assign and deliver checks, drafts and other order for the payment
of money which are payable to the order of the corporation.

                                   AMENDMENTS
 
     These By-Laws may be altered or repealed and new By-Laws may be made by the
affirmative vote, at any meeting of the Board, of a majority of the whole Board
of Directors, subject to the rights of the stockholders of the Corporation to
amend or repeal By-Laws made or amended by the Board of Directors by the
affirmative vote of the holders of record of a majority in number of shares of
the outstanding stock of the Corporation present or represented at any meeting
of the stockholders and entitled to vote thereon, provided that notice of the
proposed action be included in the notice of such meeting.

</TABLE>
 
Primary earnings (loss) per common share are computed by dividing net income
(loss), after deduction of preferred stock dividends, by the weighted average
number of common shares and common share equivalents outstanding. Common share
equivalents are computed using the treasury stock method. Under the treasury
stock method, an average market price is used to determine the number of common
share equivalents for primary earnings per common share. The higher of the
average or end of period market price is used to determine common share
equivalents for fully diluted earnings per common share. In addition, the if-
converted method is used for convertible preferred stock when computing fully
diluted earnings (loss) per common share. Redeemable preferred stock dividends
were not significant to any period presented.
 
Earnings (loss) per common share may not compute due to the level of rounding in
this exhibit.
 
(1)  Including the effect of stock options in the computation of loss per common
     share for 1991 would be antidilutive and therefore, no common stock
     equivalents are included in the 1991 computation.
 
(2)  Conversion of the preferred stock was based on a November 1992 issuance
     date.
