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, 1994. These coal shipments were destined for coal-fired electric generating
stations located 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
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.
 
INTERMODAL
 
  Intermodal transportation consists of hauling freight containers or truck
trailers by a combination of water, rail and motor carriers. The intermodal
business has become highly service-driven, and in some cases motor carriers and
railroads have begun to jointly market intermodal service. Railroad's
intermodal transportation system integrates the movement of approximately 36
daily trains operating between 32 rail hubs and 27 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 over 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.
 
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 and aerospace products. Through the
development and implementation of 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.

<PAGE>
 
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 steel coils to wire and nails.
 
ALUMINUM, NONFERROUS METALS & ORES
 
  The Aluminum, Nonferrous 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.

  In 1994, 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, 1994, approximately 19,140 miles of Railroad's track consisted of
112-lb. per yard or heavier rail, including approximately 10,738 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
197 freight locomotives under power purchase agreements.
 
  The average age of locomotives and freight cars was 15.0 years and 18.6
years, respectively, at December 31, 1994, compared with 14.5 years and 18.6
years, respectively, at December 31, 1993.
 
  The average percentage of BN's locomotives and freight cars awaiting repairs
during 1994 was 7.7 and 3.1, respectively, compared with 7.7 and 3.3,
respectively, in 1993. The average time between locomotive failures was 71.1
days in 1994 compared with 67.9 days in 1993.
 
  In 1993, BN entered into an agreement to acquire 350 alternating current
traction motor locomotives. In December 1994, the number of locomotives to be
acquired under this agreement was increased to 404. 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.
As of January 31, 1995, BN had accepted delivery of 147 locomotives and
anticipates deliveries under this agreement of between approximately 60 and 140
each year from 1995 (including January 1995 deliveries) through 1997.
 
EMPLOYEES
 
  BN employed an average of 30,711 employees in 1994 compared with 30,502 in
1993 and 31,204 in 1992. BN's payroll and employee benefits costs, including
capitalized labor costs, were approximately $2.0 billion for the year ended
December 31, 1994 and $1.9 billion for each of the years ended December 31,
1993 and 1992. Almost 90 percent of BN's employees are covered by collective
bargaining agreements with 14 different labor organizations.
 
  In December 1994, BN reached an agreement with the Railroad Yardmasters
Division (Yardmasters) of the United Transportation Union which is effective
through 1999 with respect to wages, work rules and all
 
                                       5
<PAGE>
 
other matters except health and welfare benefits. Any changes negotiated with
the other unions regarding health and welfare benefits on a national basis will
also apply to the BN Yardmasters. Approximately 250 Yardmasters were affected
by this agreement. Also during 1994, agreements were signed with all of the
unions establishing non-contributory 401(k) plans for union employees.
 
  Labor agreements currently in effect for unions other than Yardmasters
include provisions which prohibited the parties from serving notices to change
wages, benefits, rules and working conditions prior to November 1, 1994. The
next wage adjustment stipulated by the existing agreements is scheduled for
July 1995 unless new agreements are reached by the parties prior to that time.
The adjustment called for by the contract is a base wage increase dependent
upon changes in the Consumer Price Index not to exceed three percent. These
cost of living increases may be offset by increases in the cost of BN's payment
rate for health and welfare benefits costs. BN joined with the other railroads
to negotiate with the unions on a multi-employer basis on November 1, 1994. At
that time, all unions were served proposals for productivity improvements as
well as other changes. The unions also served notices on the railroads which
proposed not only increasing wages and benefits but also restoring many of the
restrictive work rules and practices that were modified or eliminated under the
current agreements. A number of the unions are also challenging the railroads'
right to negotiate nationally on a multi-employer basis and the issue is
currently pending in Federal District Court in Washington, D.C. At this time,
negotiations on the proposals by both the railroads and the unions are in
preliminary stages and the ultimate outcome of these negotiations cannot be
predicted.
 
  In July 1993, the American Train Dispatchers Association ratified an April
1993 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 The Atchison, Topeka & Santa
Fe Railway Company; Chicago & Northwestern Transportation Company (C&NW); CP
Rail System; Southern Pacific Transportation Company; and Union Pacific
Railroad Company (UP Rail).
 
  Coal, one of BN's primary commodities, has experienced significant pressure
on rates due to competition from the joint effort of C&NW/UP Rail 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
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. Circuit's
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 Railroad's 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. On October 28, 1994, plaintiffs
filed their opening evidence arguing that the revenue received by Railroad
exceeded the stand alone costs of transporting that traffic and that Railroad's
rates were unreasonably high. The ICC has issued a procedural schedule calling
for the receipt of Railroad's evidence on February 27, 1995. Railroad sought
reconsideration of that schedule and the ICC granted Railroad's request to
extend the filing date until March 29, 1995 in a decision served February 13,
1995. On January 19, 1995, Railroad moved to dismiss the case on the basis that
complainants had failed to state a prima facie case. The ICC denied the motion
on February 13, 1995.
 
COAL TRANSPORTATION CONTRACT LITIGATION
 
  On April 26, 1991, an action was filed against Railroad in the 102nd Judicial
District Court for Bowie County, Texas seeking a reduction of the
transportation rates required to be paid under two contracts (Southwestern
Electric Power Company v. Burlington Northern Railroad Company, No. D-102-CV-
91-0720). The plaintiff, Southwestern Electric Power Company (SWEPCO), was
challenging the contract rates for transportation of coal to its electric
generating facilities at Cason, Texas and Flint Creek, Arkansas. SWEPCO
contended that productivity gains achieved by Railroad constituted unusual
economic conditions giving rise to a "gross inequity" because Railroad's costs
of providing service have been reduced over the contracts' terms. On August 2,
1994, plaintiff filed an amendment to its complaint to further allege that
Railroad had been unjustly enriched by retaining differences between the rates
actually charged and those that should have been charged. SWEPCO sought both
prospective rate relief and recovery of alleged past overcharges.
 
                                       7
<PAGE>
 
  Railroad's primary contention was that both parties anticipated productivity
gains in the rail industry when negotiating the contracts and agreed that
Railroad would retain most of its productivity gains. Railroad further
contended that there was no agreement that transportation rates paid by SWEPCO
would be based on Railroad's costs of providing service.
 
  On November 18, 1994, the jury rendered a verdict denying plaintiff's request
for prospective rate relief and that plaintiff take nothing on its principal
claims of "gross inequity." However, Railroad was assessed damages
approximating $56 million relating to plaintiff's alternative claim of unjust
enrichment. On January 20, 1995, the trial court rendered a judgment on the
verdict in an amount approximating $74 million, which included attorneys' fees
and interest. The judgment further awarded post judgment interest at 10 percent
per annum and issued declaratory orders pertaining to the two contracts.
Railroad intends to appeal the judgment. In the opinion of outside counsel,
Railroad has a substantial likelihood of prevailing on appeal, although no
assurances can be given due to the uncertainties inherent in litigation.
Railroad plans to file its Notice of Appeal in the case on February 17, 1995
and will post a bond to stay enforcement of the judgment pending prosecution of
all appeals. In the event SWEPCO fails to file a motion for new trial on or
before February 21, 1995, Railroad's appeal will be effective. If such a motion
for new trial were timely filed, the trial court's jurisdiction would extend 75
days from the date of judgment to rule on SWEPCO's motion, and Railroad would
refile its appeal at the appropriate time.
 
ENVIRONMENTAL PROCEEDING
 
  On May 25, 1994, the United States Department of Justice (Department) filed
suit on behalf of the United States Environmental Protection Agency (EPA)
against Railroad in United States District Court for the Eastern District of
Wisconsin for the release of oil and hazardous substances into navigable waters
of the United States in the course of three derailments. Specifically
referenced are (1) the alleged release of hazardous substances into the Nemadji
River and its shoreline near Superior, Wisconsin, on June 30, 1992, (2) the
alleged release of oil into the North Platte River and its shoreline near
Guernsey, Wyoming, on January 9, 1993, and (3) the alleged release of oil into
a tributary of the Bighorn River near Worland, Wyoming, on May 6, 1993. The
suit claims that pursuant to 33 U.S.C. Section 1321(b)(7), Railroad is liable
to the United States for civil penalties of up to $25,000 per day of violation
or $1,000 per barrel of oil or per reportable quantity of each hazardous
substance discharged. The EPA initially calculated the statutory maximum
penalty associated with these three spills to be $10,137,000. Railroad has
answered the complaint and opposed the penalties sought by the EPA.
 
  On February 13, 1995, Railroad attended a settlement conference with the
Department. The settlement conference was called and conducted by the United
States Judge Magistrate for the Western District of Wisconsin. At the
conference, a settlement in principle was achieved. Pursuant to the compromise,
Railroad will pay $1,500,000 to satisfy all claims by the United States for
fines, penalties, response costs and natural resource damages. Railroad will
also make a $100,000 contribution to a study (jointly approved by Railroad and
the Department) regarding methods or procedures to improve rail safety and
prevent derailments. In return for these payments, the United States will
release Railroad from all claims arising out of the three derailments and
provide Railroad contribution protection against claims by other responsible
parties who may later be pursued by the government for their liability arising
from the derailments.
 
  The settlement is subject to documentation, formal sign-off by various
government officials and court approval. Railroad anticipates that the
settlement will be executed, approved and implemented by March 30, 1995. There
is no reason to believe that formal government and court approval will not be
forthcoming.
 
MERGER-RELATED LITIGATION
 
  Several complaints have been filed arising out of BNI's proposed merger (the
Merger) with Santa Fe Pacific Corporation (Santa Fe) pursuant to which Santa Fe
would merge with and into BNI, and BNI would be the surviving corporation.
Between June 30, 1994, shortly after announcement of the Merger, and October
14, 1994, twelve purported stockholder class action suits were filed on behalf
of Santa Fe stockholders in the Court of Chancery of the State of Delaware. On
October 14, 1994, plaintiffs filed a class action complaint which consolidated
and superseded all of the pending stockholder complaints (In re Santa Fe
Pacific
 
                                       8
<PAGE>
 
Corporation Shareholder Litigation, Consol. C.A. No. 13587). The Consolidated
and Amended Complaint names as defendants Santa Fe, the individual members of
the Board of Directors of Santa Fe, and BNI. Plaintiffs seek certification of a
class action on behalf of stockholders of Santa Fe as of June 30, 1994.
 
  The Consolidated and Amended Complaint, in addition to making allegations
against Santa Fe and Santa Fe's directors, alleges that BNI aided and abetted
Santa Fe's directors in breaches of their fiduciary duties, including their
fiduciary duties of good faith, loyalty, care and disclosure. The Consolidated
and Amended Complaint alleges that BNI aided and abetted various acts or
omissions by Santa Fe's directors in respect of the proposed merger with BNI,
including their allegedly material misrepresentations in and failure to
completely disclose all material information in the joint proxy
statement/prospectus dated October 12, 1994 (the Joint Proxy
Statement/Prospectus).
 
  In the Consolidated and Amended Complaint, plaintiffs ask the court to order
Santa Fe's directors to carry out their fiduciary duties to plaintiffs; enjoin
consummation of the Merger; order the Santa Fe directors to explore alternative
transactions and to negotiate in good faith with all interested persons,
including Union Pacific Corporation (UP); order the Santa Fe directors to
provide access to information concerning Santa Fe or the Merger to any bona
fide bidder, including UP; in the event the Merger is consummated, rescind the
Merger and award rescissory damages; decree that the original merger agreement
between BNI and Santa Fe (the Original Agreement) has an implied right of
termination in response to a superior offer for Santa Fe or, in the
alternative, invalidate the Original Agreement as unlawful for failing to
include such a termination provision; award damages; order an accounting by
defendants of all profits realized by them as a result of these wrongful
actions and to hold these profits in a constructive trust pending the
accounting; and award costs and disbursements including reasonable attorneys'
and experts' fees.
 
  On October 26, 1994, BNI filed a Motion to Dismiss the Consolidated and
Amended Complaint.
 
  On October 6, 1994, UP filed in the Court of Chancery of the State of
Delaware a lawsuit against Santa Fe, Santa Fe's directors and BNI (Union
Pacific Corporation v. Santa Fe Pacific Corporation, C.A. No. 13778). This
complaint alleged that Santa Fe's directors have breached their fiduciary
duties by rejecting UP's merger proposal "out of hand", by refusing to
negotiate with UP, and by threatening to bring suit against UP and its Chief
Executive Officer.
 
  In the October 6, 1994 complaint, UP seeks a declaration that the Original
Agreement permits Santa Fe to terminate the Original Agreement in order to
accept UP's merger proposal or, in the alternative, that the Original Agreement
is invalid and unenforceable for failing to include such a provision;
injunctive relief mandating Santa Fe to negotiate with UP regarding UP's merger
proposal; a declaration that UP has not tortiously interfered with the
contractual or other legal rights of BNI or Santa Fe; an injunction preventing
BNI and Santa Fe from bringing or maintaining any action against UP alleging
that UP has tortiously interfered with defendants' contractual or other legal
rights; and an award of UP's costs in bringing its lawsuit, including
reasonable legal fees.
 
  On October 7, 1994, both UP and the stockholder plaintiffs moved the court
for expedited discovery and an expedited hearing on their motions for a
preliminary injunction on a schedule that would enable the motion to be heard
and decided before Santa Fe's stockholders voted at a stockholders' meeting on
November 18, 1994. On October 18, 1994, after receiving submissions from the
parties, Vice Chancellor Jacobs denied plaintiffs' motion for expedited
proceedings because plaintiffs had "failed to demonstrate a need for this Court
to involve itself in this dispute before Santa Fe's stockholders decide whether
or not to approve the Santa Fe-BNI merger."
 
  On October 19, 1994, UP filed a First Amended and Supplemental Complaint. In
addition to repeating the allegations and requested relief of UP's earlier
Complaint, the First Amended and Supplemental Complaint adds James A. Shattuck
as an additional plaintiff, alleges that Santa Fe has made purportedly false
and misleading statements in the Joint Proxy Statement/Prospectus and elsewhere
regarding the UP
 
                                       9
<PAGE>
 
proposal and the Merger, including statements denying that Santa Fe's directors
have the purported right to terminate the Original Agreement in order to enter
into a merger agreement with UP based upon the UP proposal and denying that the
Original Agreement is allegedly void for failing to include such a right,
statements failing to disclose the purportedly preclusive effect to the
Original Agreement on the Santa Fe directors' consideration of other
combination proposals, including the UP proposal, statements allegedly
suggesting that the UP proposal does not represent a fair price, and statements
allegedly misrepresenting UP's objectives in proposing a UP-Santa Fe merger and
the likelihood of obtaining ICC approval of such a merger. The First Amended
and Supplemental Complaint seeks, in addition to the relief requested in UP's
original Complaint, further declaratory and injunctive relief consisting of a
declaration that the Joint Proxy Statement/Prospectus is false and misleading,
an injunction preventing Santa Fe from making any further allegedly materially
false and misleading statements regarding the UP Proposal or the merger and an
injunction against the November 18, 1994 Santa Fe stockholder meeting.
 
  On November 2, 1994, BNI moved pursuant to Chancery Court Rule 12(b)(6) to
dismiss the First Amended and Supplemental Complaint filed by UP and James
Shattuck on the grounds that the First Amended and Supplemental Complaint fails
to state a claim against BNI upon which relief can be granted.
 
  On January 18, 1995, UP filed a Motion for Leave to File a Second Amended and
Supplemental Complaint (the Proposed Complaint). The Proposed Complaint alleges
many of the facts asserted in the First Amended and Supplemental Complaint of
October 19, 1994. In addition, the Proposed Complaint alleges that the last
transaction proposed by UP is superior to that proposed by BNI and that the
Santa Fe Board of Directors has allegedly refused, in breach of its fiduciary
duties, to fairly and equally consider UP's superior bid. The Santa Fe Board of
Directors is instead alleged to have favored BNI through the purported
establishment of an unfair and coercive process that includes 1) the Santa Fe
Board of Director's implementation of a poison pill rights plan; 2) its
approval of a break up fee (including expense reimbursement) that allegedly
favors BNI's proposal; and 3) its alleged public expression of the view that
Santa Fe is not "for sale" despite the protracted bidding contest that is under
way. The Proposed Complaint also alleges that the first step of the BNI-Santa
Fe merger, which involves the purchase of 33 percent of the outstanding stock
of Santa Fe and BNI in exchange for cash, would "irreparably harm Santa Fe's
shareholders by an irreversible restructuring." The Proposed Complaint alleges
1) that the Santa Fe Board of Director defendants breached their fiduciary
duties of loyalty and care; and 2) that BNI aided and abetted the Santa Fe
Board of Directors' breaches of fiduciary duty. In addition to the relief that
UP sought in its October 19, 1994 complaint, the Proposed Complaint seeks,
among other things, 1) an injunction requiring Santa Fe to adopt fair and
equitable procedures for the acceptance and consideration of competing bids for
Santa Fe; 2) an injunction against the operation of the Santa Fe poison pill,
or an injunction requiring the Santa Fe Board of Directors to redeem the poison
pill rights or to otherwise render them inapplicable or unenforceable to the UP
tender offer and merger proposal; and 3) a declaration that the termination fee
and expense reimbursement payments contained in the BNI proposal are invalid
and unenforceable.
 
  On January 26, 1995, the plaintiffs in the Santa Fe stockholder litigation
filed a motion for a preliminary injunction seeking to enjoin Santa Fe's Board
of Directors from taking certain allegedly improper actions, including actions
intended to render Santa Fe's rights plan inapplicable to any proposal to
acquire Santa Fe. The stockholder plaintiffs also filed a motion requesting
expedited proceedings.
 
  On January 26, 1995, UP filed a motion for a preliminary injunction seeking
to require Santa Fe's Board of Directors to render Santa Fe's rights plan
inapplicable to UP's offer to acquire Santa Fe. UP also filed a motion
requesting expedited proceedings.
 
  On January 30, 1995, the Court of Chancery of the State of Delaware issued a
written opinion denying the motions of the plaintiff stockholders and UP for
expedited proceedings and refusing to schedule a hearing on their motions for
preliminary injunctions.
 
  On January 31, 1995, UP withdrew its acquisition proposal for Santa Fe.
 
  The stockholder plaintiffs have indicated that they intend to pursue their
claims. A trial has tentatively been scheduled to commence on June 12, 1995.
 
  BNI believes that these lawsuits are without merit and intends to oppose them
vigorously.

- --------
 (1) The 1991 pre-tax special charge related 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.
 (2) 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 note exchange
     agreements and the purchase of certain debentures. The net income for the
     year ended December 31, 1990 included a resulting extraordinary gain, net
     of income taxes, of $14 million, or $.18 per common share.
 (3) Results for 1994 reflected the cumulative effect of the implementation of
     the accounting standard for postemployment benefits (Statement of
     Financial Accounting Standards (SFAS) No. 112). The cumulative effect of
     the adoption of SFAS No. 112 decreased 1994 net income by $10 million, or
     $.11 per common share.
 (4) Results for 1992 reflected 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
     (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.
 (5) Results for 1993 included the effects of the Omnibus Budget Reconciliation
     Act of 1993 (the Act) which was signed into law in 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.
 (6) Beginning in November 1991, shares used in the computation of earnings
     (loss) per common share reflect a November 1991 public offering of
     10,350,000 shares.
 (7) Fully diluted earnings (loss) per common share are computed by dividing
     net income (loss) by the weighted average number of common shares and
     common share equivalents outstanding. The higher of the average or end-of-
     period market price is used to determine common share equivalents for
     fully diluted earnings per share under the treasury stock method. In
     addition, the if-converted method is used for convertible preferred stock
     when computing fully diluted earnings per common share.
 (8) 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.
 (9) The 1991 operating ratio excluded the special charge discussed in note (1)
     above.
(10) 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 $789 million in 1994, compared with $578 million in 1993 and
$680 million in 1992. The increase in cash from operations in 1994 over 1993
was primarily attributable to a $120 million increase in net income and a $68
million decrease in labor-related payments. The decrease in cash from
operations in 1993 compared with 1992 was primarily attributable to an $81
million increase in labor-related payments, a larger decline in the level of
accounts receivables sold
 
                                       16
<PAGE>
 
and a one-time settlement agreement payment received in 1992. These items were
partially offset by a decrease in interest paid during 1993. While operating
cash flows for 1994 and 1993 were sufficient to fund dividends, such cash flows
were not sufficient to also completely fund capital expenditures; therefore,
some capital expenditures were financed with debt and capital leases. In 1992,
operating cash flows were sufficient to fund both dividends and capital
expenditures.
 
  In 1993, BN entered into an agreement to acquire 350 alternating current
traction motor locomotives. In December 1994, the number of locomotives to be
acquired under this agreement was increased to 404. As of January 31, 1995, BN
had accepted delivery of 147 locomotives and anticipates deliveries under this
agreement of between approximately 60 and 140 each year from 1995 (including
January 1995 deliveries) 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 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.
 
  Railroad maintains an effective program for the issuance, from time to time,
of commercial paper. These borrowings are supported by Railroad's bank
revolving credit agreements. Outstanding commercial paper balances are
considered as reducing available borrowings under these agreements. The bank
revolving credit agreements allow borrowings of up to $300 million on a short-
term basis and $500 million on a long-term basis. Annual facility fees are
currently 0.125 and 0.1875 percent, respectively, and are subject to change
based upon changes in Railroad's senior secured debt ratings. At Railroad's
option, borrowings can be obtained through either a competitive bid or a
standby procedure. Rates for borrowings under the standby procedure are, at
Railroad's option, based upon the London Interbank Offered Rate (LIBOR) or
certificate of deposit rate, plus in either case, a spread based upon
Railroad's senior secured debt ratings, or an alternate base rate. The
agreements are currently scheduled to expire on May 5, 1995 and May 6, 1999,
respectively. The maturity value of commercial paper outstanding at December
31, 1994 was $91 million, leaving a total of $209 million of the short-term
revolving credit agreement available and $500 million of the long-term
revolving credit agreement available. The maturity value of commercial paper
outstanding at December 31, 1993 was $27 million. BN contemplates renewing the
short-term credit agreement, or alternatively using the long-term agreement to
support commercial paper issuances.
 
  Railroad's agreement to sell, on a revolving basis, an undivided percentage
ownership interest in a designated pool of accounts receivable with limited
recourse expired in December 1994. At December 31, 1993 and 1992, accounts
receivable were net of $100 million and $189 million, respectively,
representing receivables sold.
 
  In November 1994, Railroad entered into a $150 million three year term loan
facility agreement with a group of commercial banks and used the proceeds to
redeem $150 million aggregate principal amount of Railroad Consolidated
Mortgage Bonds, 10 percent, Series J, due November 1, 1997. The three year term
loans bear interest at rates equal to the selected LIBOR, which may vary during
the term of the loans, plus each lenders' interest rate margin.
 
  In May 1994, BNI issued $150 million of 7.4 percent notes due May 15, 1999
and used the proceeds to retire $150 million aggregate principal amount of
Railroad Consolidated Mortgage Bonds, 8 7/8 percent, Series I, due May 30,
1994. The 7.4 percent notes were the initial offering under an effective
registration statement on Form S-3 covering the issuance, from time to time, of
up to $500 million aggregate principal amount of debt securities. This issuance
reduced the amount available for future issuance to $350 million.
 
  In April 1994, Railroad completed a $50 million cross-border leveraged lease
of equipment which is recorded as a capital lease obligation. The transaction
included the issuance of $40 million of equipment secured debt at a weighted
average yield of 7.27 percent and the receipt of an up front cash benefit. The
up front benefit reduces the effective interest rate on the debt to 6.64
percent.
 
                                       17
<PAGE>
 
  In December 1993, BNI financed equipment through the issuance of $78 million
of 6.32 percent notes due serially 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.
 
  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.
 
 Capital expenditures and resources
 
  A breakdown of capital expenditures is set forth in the following table (in
millions):

  The above capital expenditures for 1994 include $50 million of equipment
acquired under a cross-border capital lease arrangement. Capital roadway
expenditures for 1994 increased compared with 1993 primarily due to spending
related to strategic initiatives for transportation network management and
extensive road improvements. Capital equipment expenditures declined when
compared to 1993 primarily as a result of acquiring more equipment through
operating leases rather than through purchases. The average age of locomotives
and freight cars at year-end 1994 was 15.0 years and 18.6 years, respectively,
compared to 14.5 years and 18.6 years, respectively, at year-end 1993.
 
  Equipment expenditures for 1993 increased compared with 1992 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.
 
  BN projects 1995 capital spending to remain at a level comparable to 1994. As
discussed in "Cash from operations and other resources," BN has a commitment to
acquire 404 alternating current traction motor locomotives through 1997, of
which 147 have been accepted as of January 31, 1995. Also, BN will continue its
implementation of several strategic initiatives for transportation network
management using information systems technology. These commitments will likely
be financed using a 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.
 
                                       18

  In addition to capital expenditures, BN continues to utilize operating leases
to fulfill certain equipment requirements. The method used to finance equipment
will depend upon current market conditions and other factors. In 1994, BN
financed new equipment through long-term operating leases. The majority of
these leases were for the alternating current traction motor locomotives.
During 1993, the long-term operating leases were primarily for intermodal
doublestack cars.
 
 Dividends
 
  Common stock dividends declared were $1.20 per common share annually for
1994, 1993 and 1992. Dividends paid on common and preferred stock during these
periods were $129 million, $125 million and $106 million, respectively. The
increase in 1993 over 1992 dividends was primarily attributable to the issuance
of 6,900,000 shares of 6 1/4 percent cumulative convertible preferred stock in
November 1992. 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 45 percent at the end of 1994 compared with 48 percent at the end of
both 1993 and 1992.
 
RESULTS OF OPERATIONS
 
 Year ended December 31, 1994 compared with year ended December 31, 1993
 
  BN had net income of $416 million ($4.37 per common share, primary, on 90.2
million shares and $4.27 per common share, fully diluted, on 97.5 million
shares) for the year ended December 31, 1994 compared with net income of $296
million ($3.06 per common share, primary, on 89.7 million shares and $3.04 per
common share, fully diluted, on 97.2 million shares) for 1993. Results for 1994
included the cumulative effect of the implementation of Statement of Financial
Accounting Standards (SFAS) No. 112 "Employers' Accounting for Postemployment
Benefits" which decreased 1994 net income by $10 million, or $.11 per common
share. 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 also 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 BN's net income by $29 million, or $.32 per common share, through the
date of enactment. This included the recognition of 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.

</TABLE>
 
  Total revenues for 1994 were $4,995 million compared with revenues of $4,699
million for 1993. The $296 million improvement was primarily attributable to
improvements in Coal ($137 million), Agricultural Commodities ($46 million) and
Intermodal ($42 million) revenues.
 
  Coal revenues improved $137 million during 1994 as a result of increased
traffic. This increase was primarily caused by a rise in the demand for
electricity as well as the need for utilities to replenish coal stockpiles
during the first half of 1994, which were partially depleted during the 1993
summer flooding. BN estimated lost coal revenues of approximately $35 million
during 1993 as a result of this flooding. Partially offsetting the increase in
1994 traffic was a decline in revenues per revenue ton mile. These lower yields
were largely due to the transportation in 1994 of greater volumes above
contractual minimum tonnage requirements on which customers received lower
rates. Continuing competitive pricing pressures in contract renegotiations also
contributed to lower yields.
 
  Revenues from the transportation of Agricultural Commodities during 1994 were
$46 million higher than 1993. This increase was principally caused by a $31
million improvement in barley revenues, higher wheat revenues and improved
feeds and minor oilseeds revenues. Barley revenues benefited from strong
domestic and export demand caused by favorable market conditions during 1994.
Higher wheat revenues resulted from an increase in yield, which is a product of
commodity mix, price and length of haul. Feeds and minor oilseeds revenues were
favorably impacted by increased domestic feed demand. Partially offsetting
these increases was an early 1994 decrease in corn revenues largely
attributable to reduced crop production and lower export demand.
 
  Intermodal revenues increased $42 million during 1994 when compared with
1993. Intermodal-international revenues accounted for the majority of the
increase with a $37 million improvement over 1993 caused by both new business
and growth in existing business. Additionally, BN AMERICA (BNA) revenues
increased due to BN's focus on traffic in its key intermodal lanes which
resulted in improved yields. The traffic increases in BN's key intermodal lanes
more than offset BN's withdrawal from the Texas market in April 1994.
 
  Forest Products, Consumer Products and Minerals Processors revenues for 1994
increased $15 million, $10 million and $13 million, respectively compared with
1993. The improvement in Forest Products revenues
 
                                       20
<PAGE>
 
was largely due to increased housing starts during the year, while Consumer
Products revenues were higher as a result of increased export demand. Minerals
Processors revenues rose as a result of stronger clays and aggregates traffic
caused by increases in both domestic and export demands.
 
  Revenues for Chemicals and Vehicles & Machinery increased $6 million and $5
million, respectively. Increased volumes for environmental logistics, chemicals
and fertilizers contributed to higher Chemicals revenues, offset partially by a
decline in petroleum products revenues. The increase in Vehicles & Machinery
revenues resulted from increased volume in automotive-international traffic.
 
  Current year revenues for Iron & Steel and Aluminum, Nonferrous Metals & Ores
were relatively flat compared with 1993.
 
  Shortlines and other, which are a net reduction of revenue, dropped $21
million compared with 1993 primarily due to additional haulage agreement
revenues and increased miscellaneous revenues.
 
  Expenses
 
  Total operating expenses for 1994 were $4,142 million compared with $4,038
million for 1993. However, the operating ratio improved three percentage points
to 83 percent from 86 percent, as increased revenues more than offset increased
operating expenses.
 
  Compensation and benefits expenses for 1994 were $70 million greater than for
the prior year. Higher traffic volumes during 1994 as well as basic wage
increases for union represented employees, three percent effective July 1993
and four percent effective July 1994, caused an increase in excess of $50
million to wages and related payroll taxes. Increased salaries and a higher
pension expense, due to a reduction in the discount rate used in determining
the net pension cost, also contributed to additional compensation and benefits
expenses.
 
  Fuel expenses were $7 million higher during 1994 as compared with 1993. The
average price paid for diesel fuel decreased 3.1 cents per gallon in 1994 to
58.4 cents despite the 4.3 cents per gallon increase in the federal fuel tax,
effective October 1, 1993, enacted as part of the Omnibus Budget Reconciliation
Act of 1993. These price savings were more than offset by a $30 million
increase in consumption due to higher traffic volumes.
 
  Materials expenses were $5 million higher during 1994 as compared with 1993.
Track and locomotive repair materials costs increased due to higher maintenance
levels and a larger fleet size in 1994. Partially offsetting these increases
were greater scrap sales due to the higher maintenance levels and a reduction
in expenditures for safety and protective equipment deployed in 1993.
 
  Equipment rents expenses were $34 million higher than 1993. This increase was
primarily attributable to higher lease expenses due to a larger fleet of leased
rail cars as well as leasing locomotives to meet power requirements. Also
contributing to the increase were payments for failure to achieve service
commitments in the first half of 1994 under various transportation agreements.
These increases were partially offset by decreased car hire expenses in 1994
compared with 1993, due to the adverse effects of the Midwest flooding in 1993.
 
  Purchased services expenses increased $15 million compared with 1993. Higher
intermodal-related costs, due to increased volumes, and higher third party
locomotive maintenance and repair costs were the most significant contributing
factors to this increase. These increases were partially offset by haulage
agreement-related reimbursements from The Atchison, Topeka and Santa Fe Railway
Company and Southern Pacific Transportation Company (SPTC) for operating
services provided by BN.
 
  Depreciation expense for 1994 was $10 million higher than 1993, due to an
increase in the asset base and higher traffic levels.
 
                                       21
<PAGE>
 
  Other operating expenses were $37 million less when compared with 1993. A $43
million decrease in costs associated with personal injury claims, excluding
wage continuation payments, and the absence in 1994 of costs associated with
the 1993 third quarter floods were partially offset by increases in derailment-
related expenses and property taxes.
 
  Interest expense for the year increased $10 million compared with 1993,
primarily due to a higher average outstanding debt balance in 1994.
 
  Other income (expense), net was $8 million lower in 1994 compared with 1993.
This resulted primarily from losses related to international ventures.
 
  The effective tax rate was 38.7 percent for 1994 compared with 43.2 percent
for 1993. The higher effective tax rate for 1993 resulted from the retroactive
increase, effective January 1, 1993, in tax rates pursuant to the provisions of
the Omnibus Budget Reconciliation Act of 1993 and the related impact on the
deferred tax liability at January 1, 1993.
 
 Year ended December 31, 1993 compared with year ended December 31, 1992
 
  BN had net income of $296 million ($3.06 per common share, primary, on 89.7
million shares and $3.04 per common share, fully diluted, on 97.2 million
shares) for 1993 compared with net income of $278 million ($3.11 per common
share, primary, on 88.6 million shares and $3.10 per common share, fully
diluted, on 89.5 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 also 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 BN's net income by $29 million, or
$.32 per common share, through the date of enactment. This included the
recognition of 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).

</TABLE>
 
  Total revenues for 1993 were $4,699 million compared with revenues of $4,630
million for 1992. The $69 million improvement was primarily attributable to
improvements in Vehicles & Machinery ($20 million), Intermodal ($19 million),
Chemicals ($17 million) and Minerals Processors ($15 million) revenues.
 
  Coal revenues for 1993 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 in 1993 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. 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 in 1993 by $15 million compared
with 1992. As drilling activity increased, export traffic for clays and
aggregates expanded, contributing to greater revenues in 1993
 
                                       23
<PAGE>
 
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 $20 million greater in 1993 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, Nonferrous Metals & Ores had
lower revenues in 1993 compared with 1992. Forest Products revenues for 1993
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 $5
million compared with 1992, primarily due to lower taconite traffic caused by
labor strikes at two large customers. Aluminum, Nonferrous Metals & Ores
revenues decreased by $5 million as aluminum production declined. Revenues for
Consumer Products during 1993 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 1993 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 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 of 1993.
 
  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 the continued emphasis of BN's safety programs.
Offsetting these increases were lower car materials expenses.
 
  Equipment rents expenses were $6 million higher in 1993 than in 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 greater 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 SPTC as the floods reduced
SPTC volumes over BN track. These increases were partially offset by decreases
in contracted locomotive repairs and consultant fees.

<PAGE>
 
  Depreciation expense for 1993 was $14 million greater than in 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, excluding wage continuation payments. 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.
 
OTHER MATTERS
 
 Casualty and environmental
 
  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, resulted in significant
increases in expense. For several years prior to 1992, the trend of significant
increases in BN's personal injury expense reflected the combined effects of
increasing frequency of claims, rising medical expenses, legal judgments and
settlements. To improve worker safety and counter increasing costs, BN
implemented a number of programs to reduce the number of personal injury claims
and the dollar amount of claim settlements, and reverse the trend of rising
expense. If these efforts continue to be successful, future expenses could be
further reduced. The total amount of personal injury costs (including wage
continuation payments) were $170 million, $216 million and $253 million in
1994, 1993 and 1992, 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 United States 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 approximately 75 sites (the PRP sites) and, in
many instances, is one of several PRPs. BN generally
 
                                       25
<PAGE>
 
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 analyses.
 
  BN is involved in a number of administrative and judicial proceedings and
other mandatory clean-up efforts at approximately 160 sites, including the PRP
sites, for which it is being asked to participate in the clean-up of sites
contaminated by material discharged into the environment. BN paid approximately
$21 million, $27 million and $20 million during 1994, 1993 and 1992,
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 $110 million in future years to remediate and
restore all known sites, including $105 million pertaining to mandated sites,
of which approximately $70 million relates to the PRP sites. Of the $110
million, BN expects to spend $33 million during 1995. Also, BN anticipates that
the majority of the $110 million will be paid out over a period of less than
seven years; however, some costs will be paid out over a longer period, in some
cases up to 40 years. At December 31, 1994, 23 sites accounted for
approximately $75 million of the accrual and no individual site was considered
to be material.
 
  Liabilities for environmental costs represent BN's best estimates for
remediation and restoration of these sites and include asserted and unasserted
claims. At December 31, 1994, BN had accrued approximately $110 million for
estimated future environmental costs and believes it is reasonably possible,
although not probable, that actual environmental costs could be lower than the
recorded reserve or as much as 50 percent higher. BN's best estimate of
unasserted claims was approximately $5 million as of December 31, 1994.
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.
 
 Hedging activities
 
  BN has a program to hedge against fluctuations in the price of its diesel
fuel purchases. This program includes forward purchases for delivery at fueling
facilities and exchange-traded petroleum futures contracts. The futures
contracts are accounted for as hedges which are marked to market with any gains
or losses associated with changes in market value being deferred and recognized
as a component of fuel expense in the period in which the designated fuel is
purchased and used. At December 31, 1994, BN had entered into agreements with
fuel suppliers setting the price of fuel to be obtained by taking physical
delivery directly
 
                                       26
<PAGE>
 
from such suppliers at a future date. The average price of the approximately 79
million gallons which BN had committed to purchase was approximately 52 cents
per gallon, exclusive of taxes, certain transportation costs and other charges.
In addition, BN held petroleum futures contracts representing approximately 53
million gallons at an average price of approximately 49 cents per gallon. These
contracts have expiration dates ranging from January to October 1995.
 
  BN's current fuel hedging program is designed to cover no more than 50
percent of projected fuel requirements for the subsequent 12-month period;
therefore, hedge positions will not exceed actual fuel requirements. The
current and future fuel delivery prices are monitored continuously and hedge
positions are adjusted accordingly. In order to reduce risk associated with
market movements, fuel hedging transactions do not extend beyond a 12-month
period. BN purchases petroleum futures contracts only through regulated
exchanges (e.g. New York Mercantile Exchange). In order to effectively monitor
the fuel hedging activities, results of the program are summarized and reported
to senior management on a regular basis.
 
  In the second quarter of 1994, BN entered into a three year interest rate
swap on a notional amount of $50 million to hedge against interest rate
exposure on one of its debt issuances. BN's position in this swap was
subsequently closed during the fourth quarter of the year. Under the terms of
this swap, BN received semiannual fixed-rate payments of 6.33 percent from a
AA-rated counterparty and made semiannual floating rate payments tied to the
six-month LIBOR. The swap was accounted for as a hedge with realized gains or
losses being recognized as a component of interest expense. During 1994, the
resulting decrease in interest expense was not significant.
 
 Proposed merger
 
  As of June 29, 1994, BNI and Santa Fe entered into an Agreement and Plan of
Merger (the Original Agreement) pursuant to which, on the terms and conditions
set forth in the Original Agreement, Santa Fe would merge (the Merger) with and
into BNI, and BNI would be the surviving corporation and each share of Santa Fe
common stock would be converted into 0.27 of a share of BNI common stock. The
Original Agreement was subsequently amended as of October 26, 1994, December
18, 1994 and January 24, 1995. The Original Agreement, as so amended, is
referred to as the Merger Agreement. Pursuant to the Merger Agreement, Santa Fe
is to merge with and into BNI with each share of Santa Fe common stock to be
exchanged for not less than 0.40 and not more than 0.4347 shares of BNI common
stock. The exchange ratio will vary based on the number of shares of Santa Fe
common stock repurchased by Santa Fe in the repurchase program referred to
below (the Repurchase Program). Stockholders of BNI and Santa Fe approved the
Merger Agreement at special stockholders' meetings held on February 7, 1995.
 
  Also pursuant to the Merger Agreement, on December 23, 1994, BNI and Santa Fe
commenced tender offers (together, the Tender Offer) to acquire up to 63
million shares of Santa Fe common stock in the aggregate at $20 per share in
cash (with Santa Fe severally obligated to purchase up to 38 million shares of
Santa Fe common stock in the Tender Offer and BNI severally obligated to
purchase up to 25 million shares of Santa Fe common stock in the Tender Offer).
The Tender Offer expired at midnight, Eastern Standard Time, on February 8,
1995, with approximately 112.6 million shares of Santa Fe common stock tendered
(based on a preliminary count). As 63 million shares of Santa Fe common stock
have been accepted for payment by BNI and Santa Fe, tenders by Santa Fe
stockholders are subject to proration. Payment for tendered shares will be made
promptly after the final proration factor is determined, which determination is
expected to be made on or about February 17, 1995. Santa Fe will purchase 38
million shares of Santa Fe common stock in the Tender Offer, and BNI will
purchase the remaining 25 million shares accepted for payment.
 
  On February 6, 1995, BNI entered into a five-year $500 million unsecured bank
credit facility (the Tender Offer Facility), whereby a group of banks will
finance BNI's obligations to purchase shares of Santa Fe common stock in the
Tender Offer. At BNI's option, borrowings can be obtained either through a
competitive bid or a standby procedure. Rates for borrowing under the standby
procedure are, at BNI's
 
                                       27
<PAGE>
 
option, based upon the selected term of LIBOR or certificate of deposit rate,
plus in either case, a spread based upon BNI's senior unsecured debt ratings
and the amount borrowed under the Tender Offer Facility, or an alternative base
rate. Santa Fe anticipates borrowing up to $1,110 million (of which
approximately $200 million will be used to replace existing Santa Fe debt) in
connection with the Santa Fe tender offer and related matters from a syndicate
of financial institutions under a new Santa Fe credit agreement. Santa Fe may
also borrow an additional $200 million under its new credit agreement to retire
$200 million of existing Santa Fe debt.
 
  Under the Repurchase Program as set forth in the Merger Agreement, Santa Fe
is permitted, at its discretion and subject to certain financial and
performance criteria of Santa Fe set forth in its credit agreements and the
Merger Agreement (including minimum cash flows, cash capital expenditures and
maximum total debt), to repurchase up to 10 million shares of Santa Fe common
stock prior to consummation of the Merger. The number of shares of BNI common
stock to be issued in the Merger will not be affected by the number of shares
of Santa Fe common stock repurchased by Santa Fe under the Repurchase Program.
Accordingly, the exchange ratio of BNI common shares to be offered for each
share of outstanding Santa Fe common stock upon consummation of the Merger
would be set at not less than 0.40 and not more than 0.4347 shares.
 
  Pursuant to the Merger Agreement, two possible structures are available to
complete the Merger. Using the current structure, each issued and outstanding
share of Santa Fe common stock (other than shares of Santa Fe common stock held
by Santa Fe as treasury stock or shares held by BNI, all of which will be
cancelled) will be exchanged for not less than 0.40 and not more than 0.4347
shares of BNI common stock depending upon the number of additional shares of
Santa Fe common stock repurchased by Santa Fe under the Repurchase Program. BNI
will be the surviving corporation. The Merger Agreement provides that either
BNI or Santa Fe may elect to effect the Merger through the use of a holding
company (the Alternative Transaction Structure) as described below. BNI and
Santa Fe have established BNSF Corporation (BNSF), a Delaware corporation, for
such purpose. Under the Alternative Transaction Structure, BNSF would create
two subsidiaries and one subsidiary would merge into BNI and one into Santa Fe.
Each holder of BNI common stock would receive one share of BNSF common stock
and each holder of Santa Fe common stock, excluding the Santa Fe common stock
acquired by BNI in the Tender Offer and the Santa Fe common stock held by Santa
Fe as treasury stock, would receive not less than 0.40 and not more than 0.4347
shares of BNSF common stock depending upon the number of shares of Santa Fe
common stock repurchased by Santa Fe under the Repurchase Program. The Santa Fe
common stock acquired by BNI in the Tender Offer would remain outstanding and
the Santa Fe common stock held by Santa Fe as treasury stock would be
cancelled. The rights of each stockholder of BNSF would be substantially
identical to the rights of a stockholder of BNI, and the Alternative
Transaction Structure would have the same economic effect with respect to the
stockholders of BNI and Santa Fe as the Merger in its current structure. The
Merger will be accounted for under the purchase method of accounting upon
consummation, and BNI's $500 million investment will be included in the
purchase price.
 
  As is typical in the context of a merger, certain benefits of officers and
employees vested upon approval of the Merger by the stockholders of BNI and
Santa Fe. In particular, on February 7, 1995, restrictions previously placed
upon certain BNI stock grants lapsed and the previously unearned compensation
relating to such restricted stock, included in BNI stockholders' equity, was
charged to compensation and benefits expense. As of December 31, 1994, such
unearned compensation relating to restricted stock was approximately $23
million. BNI expects to incur other costs related to the Merger some of which
will be included in the determination of the total purchase price.
 
  Consummation of the Merger is subject to approval by the Interstate Commerce
Commission (ICC), approval under the Hart-Scott-Rodino Antitrust Improvements
Act of 1976, and other customary conditions. In connection with the ICC
proceedings, on January 27, 1995, BNI and Santa Fe requested the ICC to adopt
an expedited procedural schedule for reviewing the merger, based on a timetable
the ICC has recently
 
                                       28
<PAGE>
 
proposed to adopt for all major railroad mergers, and on February 3, 1995, the
ICC issued a notice requesting comments on the proposed schedule by February
21, 1995. That schedule calls for the ICC to issue its decision on the merger
within 165 days from the date on which the ICC publishes a notice formally
advising parties that the BNI and Santa Fe stockholders have voted to approve
the transaction. The ICC has not yet issued a notice regarding stockholder
approval nor taken any further action on the proposed schedule.
 
  On October 5, 1994, Union Pacific Corporation (UP) submitted a proposal to
Santa Fe pursuant to which UP would acquire Santa Fe. UP modified its proposal
on several occasions and, on January 31, 1995, withdrew its acquisition
proposal for Santa Fe.
 
 Other
 
  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.
 
  In December 1994, BN reached an agreement with the Railroad Yardmasters
Division (Yardmasters) of the United Transportation Union which is effective
through 1999 with respect to wages, work rules and all other matters except
health and welfare benefits. Any changes negotiated with the other unions
regarding health and welfare benefits on a national basis will also apply to
the BN Yardmasters. Approximately 250 Yardmasters were affected by this
agreement. Also during 1994, agreements were signed with all of the unions
establishing non-contributory 401(k) plans for union employees.
 
  Labor agreements currently in effect for unions other than Yardmasters
include provisions which prohibited the parties from serving notices to change
wages, benefits, rules and working conditions prior to
November 1, 1994. The next wage adjustment stipulated by the existing
agreements is scheduled for July 1995 unless new agreements are reached by the
parties prior to that time. The adjustment called for by the contract is a base
wage increase dependent upon changes in the Consumer Price Index not to exceed
three percent. These cost of living increases may be offset by increases in the
cost of BN's payment rate for health and welfare benefits costs. BN joined with
the other railroads to negotiate with the unions on a multi-employer basis on
November 1, 1994. At that time, all unions were served proposals for
productivity improvements as well as other changes. The unions also served
notices on the railroads which proposed not only increasing wages and benefits
but also restoring many of the restrictive work rules and practices that were
modified or eliminated under the current agreements. A number of the unions are
also challenging the railroads' right to negotiate nationally on a multi-
employer basis and the issue is currently pending in Federal District Court in
Washington, D.C. At this time, negotiations on the proposals by both the
railroads and the unions are in preliminary stages and the ultimate outcome of
these negotiations cannot be predicted.
 
  In July 1993, the American Train Dispatchers Association ratified an April
1993 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.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
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.
 
 Cash and cash equivalents
 
  All short-term investments with original maturities of less than 90 days 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.
 
 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 their 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, which would include major casualty losses, abandonments, sales and
obsolescence of assets; are recorded as gains or losses at the time of their
occurrence. 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 tax expense determined by the change in the net
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. Investment tax credits were accounted for
under the "flow-through" method.
 
 Earnings per common share
 
  Primary earnings per common share are computed by dividing net income, after
deduction of preferred stock dividends, by the weighted average number of
common shares and common share equivalents outstanding. Fully diluted earnings
per common share are computed by dividing net income by the weighted average
number of common shares and common share equivalents outstanding. Common share
equivalents are computed using 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 per common share.

2. ACCOUNTS RECEIVABLE, NET
 
  Railroad's agreement to sell, on a revolving basis, an undivided percentage
ownership interest in a designated pool of accounts receivable with limited
recourse expired in December 1994. At December 31, 1993, accounts receivable
were net of $100 million, representing receivables sold. Average monthly
proceeds from the sale of accounts receivable were $162 million, $182 million
and $190 million in 1994, 1993 and 1992, respectively. Included in other income
(expense), net were expenses of $9 million in 1994 and 1993 and $11 million in
1992, relating to the sale. BN maintains an allowance for doubtful accounts
based upon the expected collectibility of all accounts receivable, which at
December 31, 1993 included receivables sold with recourse. Allowances for
doubtful accounts of $20 million and $17 million have been recorded at December
31, 1994 and 1993, respectively.

</TABLE>
 
  The consolidated balance sheets at December 31, 1994 and 1993 included $77
million and $36 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
$34 million and $31 million at December 31, 1994 and 1993, 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. 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. 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 a periodic basis. Results of service life
studies are recorded over the remaining life of the asset group studied. No
service life studies were scheduled for 1994. In future periods, service life
studies will be conducted as required. However, the impact of such studies is
not determinable at this time.
 
  Capitalization of certain software development costs has increased as a
result of new strategic initiatives. Capitalization of software development
costs begins upon establishment of technological feasibility. 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. Amortization expense was
$2 million for the year ended December 31, 1994 and no amortization was
recorded for the year ended December 31, 1993. Unamortized capitalized software
costs were $20 million and $6 million as of December 31, 1994 and 1993,
respectively.

  Railroad maintains an effective program for the issuance, from time to time,
of commercial paper. These borrowings are supported by Railroad's bank
revolving credit agreements. Outstanding commercial paper balances are
considered as reducing available borrowings under these agreements. The bank
revolving credit agreements allow borrowings of up to $300 million on a short-
term basis and $500 million on a long-term basis. Annual facility fees are
currently 0.125 and 0.1875 percent, respectively, and are subject to change
based upon changes in Railroad's senior secured debt ratings. At Railroad's
option, borrowings can be obtained through either a competitive bid or a
standby procedure. Rates for borrowings under the standby

procedure are, at Railroad's option, based upon the London Interbank Offered
Rate (LIBOR) or certificate of deposit rate, plus in either case, a spread
based upon Railroad's senior secured debt ratings, or an alternate base rate.
The agreements are currently scheduled to expire on May 5, 1995 and May 6,
1999, respectively. The maturity value of commercial paper outstanding at
December 31, 1994 was $91 million, leaving a total of $209 million of the
short-term revolving credit agreement available and $500 million of the long-
term revolving credit agreement available. The maturity value of commercial
paper outstanding at December 31, 1993 was $27 million.
 
  In November 1994, Railroad entered into a $150 million three year term loan
facility agreement with a group of commercial banks and used the proceeds to
redeem $150 million aggregate principal amount of Railroad Consolidated
Mortgage Bonds, 10 percent, Series J, due November 1, 1997. Under the terms of
the indenture, the 10 percent mortgage bonds were redeemable at par, commencing
November 1, 1994. The difference between Railroad's redemption price and the
net carrying value resulted in an insignificant loss. The three year term loans
bear interest at rates equal to the selected LIBOR, which may vary during the
term of the loans, plus each lender's interest rate margin.
 
  The financial covenants of the two bank revolving credit agreements and the
three year term loan facility agreement require that Railroad's consolidated
tangible net worth, as defined in the agreements, be at least $1.7 billion, and
that its debt, as defined in the agreements, cannot exceed the lesser of 140
percent of its consolidated tangible net worth and $3 billion. Each of the
agreements contain 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 the BNI Board of
Directors nor appointed by directors so nominated. The proposed merger between
BNI and Santa Fe Pacific Corporation (Santa Fe) will not constitute a "Change
in Control" under such agreements.
 
  In December 1994, BNI entered into an agreement whereby Chemical Bank
(Chemical) and Texas Commerce Bank National Association (TCB) agreed to provide
a five-year $500 million unsecured bank credit facility (the Tender Offer
Facility) for the purpose of funding BNI's tender offer to purchase 25 million
shares of Santa Fe common stock at $20 per share. At BNI's option, borrowings
can be obtained either through a competitive bid or a standby procedure. Rates
for borrowing under the standby procedure are, at BNI's option, based upon the
selected term of LIBOR or certificate of deposit rate, plus in either case, a
spread based upon BNI's senior unsecured debt ratings and the amount borrowed
under the Tender Offer Facility, or an alternative base rate. In February 1995,
a group of banks executed a definitive agreement for the Tender Offer Facility.
 
  In May 1994, BNI issued $150 million of 7.4 percent notes due May 15, 1999
and used the proceeds to retire $150 million aggregate principal amount of
Railroad Consolidated Mortgage Bonds, 8 7/8 percent, Series I, due May 30,
1994. The 7.4 percent notes were the initial offering under an effective
registration statement on Form S-3 covering the issuance, from time to time, of
up to $500 million aggregate principal amount of debt securities. This issuance
reduced the amount available for future issuance to $350 million.
 
  In April 1994, Railroad completed a $50 million cross-border leveraged lease
of equipment which is recorded as a capital lease obligation. The transaction
included the issuance of $40 million of equipment secured debt at a weighted
average yield of 7.27 percent and the receipt of an up front cash benefit. The
up front benefit reduces the effective interest rate on the debt to 6.64
percent.
 
  In December 1993, BNI financed equipment through the issuance of $78 million
of 6.32 percent notes due serially 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.

  Aggregate long-term debt scheduled maturities for 1995 through 1999 and
thereafter are $32 million, $27 million, $253 million, $27 million, $174
million and $1,279 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. Equipment obligations are secured by the underlying equipment.
 
5. DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS
 
  The estimated fair values of BN's financial instruments at December 31, 1994
and 1993 and the methods and assumptions used to estimate the fair value of
each class of financial instruments held by BN, were as follows:
 
 Cash and cash equivalents
 
  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 10.0 percent to 10.8 percent at
December 31, 1994 and 8.7 percent at December 31, 1993, were determined to be
appropriate when considering current United States Treasury rates and the
credit risk associated with these notes.
 
 Marketable securities
 
  Marketable securities, which are pledged to fund liabilities of certain
employee benefit plans, consist of corporate bonds (57 percent of carrying
amount) and United States government or agency issues (43 percent of carrying
amount) and are classified as available for sale. The carrying value of
available for sale securities is adjusted for changes in fair value and any
unrealized gains or losses are recorded as a component of stockholders' equity.
At December 31, 1994, the unrealized gains and losses were immaterial. The fair
value for these securities was based on secondary market indicators. Realized
gains or losses from the sales of marketable securities are based on the
specific identification method and were also immaterial for 1994.

</TABLE>
 
 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 United States 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.
 
 Recourse liability from sale of receivables
 
  Railroad's agreement to sell, on a revolving basis, an undivided percentage
interest in a designated pool of accounts receivable with limited recourse
expired in December 1994. At December 31, 1993, 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):

original cost of $16 million and $19 million in the December 31, 1994 and 1993
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
principal payments which are based on traffic volume over a segment of line.
The carrying value of the note was $5 million at December 31, 1994 and 1993. 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.
 
6. HEDGING ACTIVITIES
 
  BN has a program to hedge against fluctuations in the price of its diesel
fuel purchases. This program includes forward purchases for delivery at fueling
facilities and exchange-traded petroleum futures contracts. The futures
contracts are accounted for as hedges which are marked to market with any gains
or losses associated with changes in market value being deferred and recognized
as a component of fuel expense in the period in which the designated fuel is
purchased and used. At December 31, 1994, BN had entered into agreements with
fuel suppliers setting the price of fuel to be obtained by taking physical
delivery directly from such suppliers at a future date. The average price of
the approximately 79 million gallons which BN had committed to purchase was
approximately 52 cents per gallon, exclusive of taxes, certain transportation
costs and other charges. In addition, BN held petroleum futures contracts
representing approximately 53 million gallons at an average price of
approximately 49 cents per gallon. These contracts have expiration dates
ranging from January to October 1995.
 
  BN's current fuel hedging program is designed to cover no more than 50
percent of projected fuel requirements for the subsequent 12-month period;
therefore, hedge positions will not exceed actual fuel requirements. The
current and future fuel delivery prices are monitored continuously and hedge
positions are adjusted accordingly. In order to reduce risk associated with
market movements, fuel hedging transactions do not extend beyond a 12-month
period. BN purchases petroleum futures contracts only through regulated
exchanges (e.g. New York Mercantile Exchange). In order to effectively monitor
the fuel hedging activities, results of the program are summarized and reported
to senior management on a regular basis.
 
  In the second quarter of 1994, BN entered into a three year interest rate
swap on a notional amount of $50 million to hedge against interest rate
exposure on one of its debt issuances. BN's position in this swap was
subsequently closed during the fourth quarter of the year. Under the terms of
this swap, BN received semiannual fixed-rate payments of 6.33 percent from a
AA-rated counterparty and made semiannual floating rate payments tied to the
six-month LIBOR. The swap was accounted for as a hedge with realized gains or
losses being recognized as a component of interest expense. During 1994, the
resulting decrease in interest expense was not significant.
 
7. INCOME TAXES
 
  Effective January 1, 1993, BN adopted Statement of Financial Accounting
Standards (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 upon adoption.

  In 1994, tax expense of $6 million related to the adjustment to reduce the
minimum pension liability was allocated directly to stockholders' equity.
 
  In August 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 1993 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

9. PREFERRED CAPITAL STOCK
 
 No Par Value Preferred Stock, authorized 25,000,000 shares--6,900,000 shares

  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, 1994, there had been no such defaults.
 
 Class A Preferred Stock Without Par Value, authorized 50,000,000 shares--
unissued
 
  At December 31, 1994, 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.
 
10. 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, 1994, there were 89,223,821 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.
 
11. 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 SAR's exercise price would be recognized at
such time as an adjustment to compensation expense.

  Shares issued upon exercise of options may be issued from treasury shares or
from authorized but unissued shares.
 
  All outstanding stock options became exercisable upon the February 7, 1995
approval by the stockholders of both BNI and Santa Fe of the proposed merger
with Santa Fe.
 
 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 177,670, 232,354 and
214,475 shares in 1994, 1993 and 1992, respectively. A total of 780,694,
870,525 and 824,877 restricted common shares were outstanding at December 31,
1994, 1993 and 1992, respectively. Compensation expense was not significantly
affected for all periods presented. Upon the February 7, 1995 approval by the
stockholders of both BNI and Santa Fe of the proposed merger with Santa Fe,
the restrictions on the BNI stock grants lapsed and the previously unearned
compensation relating to such restricted stock, included in BNI's
stockholders' equity, was recognized as

a non-cash charge to compensation and benefits expense. As of December 31,
1994, such unearned compensation relating to restricted stock was approximately
$23 million.
 
  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 stockholder 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, 1994, 1993 and 1992, 3,900,
5,540, and 11,720 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 years
ended December 31, 1994 and 1993, 31,832 and 34,629 shares were purchased under
this plan. The related compensation expense was not significant.
 
12. 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 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 funded status of BN plans and the net accrued pension cost reflected in
the consolidated balance sheets were as follows (in millions):

  Net pension cost, which is based upon a discount rate as of January 1, was
higher for 1994 than 1993 primarily due to a decrease in the discount rate from
8.5 percent at January 1, 1993 to 7 percent at January 1, 1994. The decrease in
net pension cost for 1993 as compared with 1992 was primarily due to a decrease
in the rate of future compensation growth from 6 percent at January 1, 1993 to
5.5 percent at January 1, 1994.
 
  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 $8 million, $6 million and $4
million in 1994, 1993 and 1992, 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.
 
13. OTHER BENEFIT PLANS
 
  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 were at least 55 years of age and who retired on or before
March 1986.
 
  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.
 
  The following table presents the status of the plans and the accrued
postretirement benefit cost reflected in the consolidated balance sheets (in
millions):

  The discount rate used in determining the benefit obligation was 9 percent at
December 31, 1994 and 7 percent at December 31, 1993. The health care cost
trend rate is assumed to decrease gradually from 14 percent in 1995 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, 1994 and 1993
as well as the aggregate of the service and interest cost components for the
three years ended December 31, 1994.
 
  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
both 1994 and 1993 and $11 million in 1992.
 
14. COMMITMENTS AND CONTINGENCIES
 
 Agreement to merge and tender offers
 
  As of June 29, 1994, BNI and Santa Fe entered into an Agreement and Plan of
Merger (the Original Agreement) pursuant to which, on the terms and conditions
set forth in the Original Agreement, Santa Fe would merge (the Merger) with and
into BNI, and BNI would be the surviving corporation and each share of Santa Fe
common stock would be converted into 0.27 of a share of BNI common stock. The
Original Agreement was subsequently amended as of October 26, 1994, December
18, 1994 and January 24, 1995. The Original Agreement, as so amended, is
referred to as the Merger Agreement. Pursuant to the Merger Agreement, Santa Fe
is to merge with and into BNI with each share of Santa Fe common stock to be
exchanged for not less than 0.40 and not more than 0.4347 shares of BNI common
stock. The exchange ratio will vary based on the number of shares of Santa Fe
common stock repurchased by Santa Fe in the repurchase program referred to
below (the Repurchase Program). Stockholders of BNI and Santa Fe approved the
Merger Agreement at special stockholders' meetings held on February 7, 1995.
 
  Also pursuant to the Merger Agreement, on December 23, 1994, BNI and Santa Fe
commenced tender offers (together, the Tender Offer) to acquire up to 63
million shares of Santa Fe common stock in the aggregate at $20 per share in
cash (with Santa Fe severally obligated to purchase up to 38 million shares of
Santa Fe common stock in the Tender Offer and BNI severally obligated to
purchase up to 25 million shares of Santa Fe common stock in the Tender Offer
or 20 percent and 13 percent, respectively, of the then outstanding Santa Fe
common stock). Prior to expiration of the Tender Offer on February 8, 1995,
Santa Fe stockholders tendered sufficient shares to complete the Tender Offer.
On February 6, 1995, BNI entered into a five-year $500 million unsecured bank
credit facility (the Tender Offer Facility), whereby a group of banks will
finance BNI's obligations to purchase shares of Santa Fe common stock in the
Tender Offer. At BNI's option, borrowings can be obtained either through a
competitive bid or a standby procedure. Rates for borrowing under the standby
procedure are, at BNI's option, based upon the selected term of LIBOR or
certificate of deposit rate, plus in either case, a spread based upon BNI's
senior unsecured debt ratings and
 
                                       47

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
the amount borrowed under the Tender Offer Facility, or an alternative base
rate. BNI's investment in Santa Fe, which represents approximately 17 percent
of Santa Fe stock outstanding following completion of the Tender Offer, will be
accounted for under the cost method until consummation of the Merger. Santa Fe
anticipates borrowing up to $1,110 million (of which approximately $200 million
will be used to replace existing Santa Fe debt) in connection with the Sante Fe
tender offer and related matters from a syndicate of financial institutions
under a new credit agreement. Santa Fe may also borrow an additional $200
million under its new credit agreement to retire $200 million of existing Santa
Fe debt. Funding of the Tender Offer is expected to be completed on or about
February 21, 1995.
 
  Under the Repurchase Program as set forth in the Merger Agreement, Santa Fe
is permitted, at its discretion and subject to certain financial and
performance criteria of Santa Fe set forth in its credit agreements and the
Merger Agreement (including minimum cash flows, cash capital expenditures and
maximum total debt), to repurchase up to 10 million shares of Santa Fe common
stock prior to consummation of the Merger. The number of shares of BNI common
stock to be issued in the Merger will not be affected by the number of shares
of Santa Fe common stock repurchased by Santa Fe under the Repurchase Program.
Accordingly, the exchange ratio of BNI common shares to be offered for each
share of outstanding Santa Fe common stock upon consummation of the Merger
would be set at not less than 0.40 and not more than 0.4347 shares.
 
  Pursuant to the Merger Agreement, two possible structures are available to
complete the Merger. Using the current structure, each issued and outstanding
share of Santa Fe common stock (other than shares of Santa Fe common stock held
by Santa Fe as treasury stock or shares held by BNI, all of which will be
cancelled) will be exchanged for not less than 0.40 and not more than 0.4347
shares of BNI common stock depending upon the number of shares of Santa Fe
common stock repurchased by Santa Fe under the Repurchase Program. BNI will be
the surviving corporation. The Merger Agreement provides that either BNI or
Santa Fe may elect to effect the Merger through the use of a holding company
(the Alternative Transaction Structure) as described below. BNI and Santa Fe
have established BNSF Corporation (BNSF), a Delaware corporation, for such
purpose. Under the Alternative Transaction Structure, BNSF would create two
subsidiaries and one subsidiary would merge into BNI and one into Santa Fe.
Each holder of one share of BNI common stock would receive one share of BNSF
common stock and each holder of one share of Santa Fe common stock, excluding
the Santa Fe common stock acquired by BNI in the Tender Offer and the Santa Fe
common stock held by Santa Fe as treasury stock, would receive not less than
0.40 and not more than 0.4347 shares of BNSF common stock depending upon the
number of shares of Santa Fe common stock repurchased by Santa Fe as permitted
under the Repurchase Program. The Santa Fe common stock acquired by BNI in the
Tender Offer would remain outstanding and the Santa Fe common stock held by
Santa Fe as treasury stock would be cancelled. The rights of each stockholder
of BNSF would be substantially identical to the rights of a stockholder of BNI,
and the Alternative Transaction Structure would have the same economic effect
with respect to the stockholders of BNI and Santa Fe as the Merger in its
current structure. The Merger will be accounted for under the purchase method
of accounting upon consummation, and BNI's $500 million investment will be
included in the purchase price.
 
  As is typical in the context of a merger, certain benefits of officers and
employees vested upon approval of the Merger by the stockholders of BNI and
Santa Fe. In particular, on February 7, 1995, restrictions previously placed
upon certain BNI stock grants lapsed and the previously unearned compensation
relating to such restricted stock, included in BNI's stockholders' equity, was
charged to compensation and benefits expense. As of December 31, 1994, such
unearned compensation relating to restricted stock was approximately $23
million. BNI expects to incur other costs related to the Merger some of which
will be included in the determination of the total purchase price.
 
  Consummation of the Merger is subject to approval by the ICC, approval under
the Hart-Scott-Rodino Antitrust Improvements Act of 1976, and other customary
conditions. In connection with the ICC

proceedings, on January 27, 1995, BNI and Santa Fe requested the ICC to adopt
an expedited procedural schedule for reviewing the merger, based on a timetable
the ICC has recently proposed to adopt for all major railroad mergers, and on
February 3, 1995, the ICC issued a notice requesting comments on the proposed
schedule by February 21, 1995. That schedule calls for the ICC to issue its
decision on the merger within 165 days from the date on which the ICC publishes
a notice formally advising parties that the BNI and Santa Fe stockholders have
voted to approve the transaction. The ICC has not yet issued a notice regarding
stockholder approval nor taken any further action on the proposed schedule.
 
 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 may exceed recorded accruals, they
are not anticipated to materially affect BN's financial condition, results of
operations or liquidity.
 
  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 United States 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 approximately 75 sites (the PRP 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 analyses.
 
  BN is involved in a number of administrative and judicial proceedings and
other mandatory clean-up efforts at approximately 160 sites, including the PRP
sites, for which it is being asked to participate in the clean-up of sites
contaminated by material discharged into the environment. BN paid approximately
$21 million, $27 million and $20 million during 1994, 1993 and 1992,
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 $110 million in future years to remediate and
restore all known sites,

<PAGE>
 
                   BURLINGTON NORTHERN INC. AND SUBSIDIARIES
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
including $105 million pertaining to mandated sites, of which approximately $70
million relates to the PRP sites. Of the $110 million, BN expects to spend $33
million during 1995. Also, BN anticipates that the majority of the $110 million
will be paid out over a period of less than seven years; however, some costs
will be paid out over a longer period, in some cases up to 40 years. At
December 31, 1994, 23 sites accounted for approximately $75 million of the
accrual and no individual site was considered to be material.
 
  Liabilities for environmental costs represent BN's best estimates for
remediation and restoration of these sites and include asserted and unasserted
claims. At December 31, 1994, BN had accrued approximately $110 million for
estimated future environmental costs and believes it is reasonably possible,
although not probable, that actual environmental costs could be lower than the
recorded reserve or as much as 50 percent higher. BN's best estimate of
unasserted claims was approximately $5 million as of December 31, 1994.
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.
 
 Lease commitments
 
  BN has substantial lease commitments for railroad, highway 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 price purchase options.
 
  Lease rental expense for operating leases was $229 million, $194 million and
$189 million for the years ended December 31, 1994, 1993 and 1992,
respectively.
 
  Minimum annual rental commitments were as follows (in millions):

 Other commitments and contingencies
 
  In 1993, BN entered into an agreement to acquire 350 alternating current
traction motor locomotives. In December 1994, the number of locomotives to be
acquired under this agreement was increased to 404. As of January 31, 1995, BN
had accepted delivery of 147 locomotives and anticipates deliveries under this
agreement of between approximately 60 and 140 each year from 1995 (including
January 1995 deliveries) through 1997.
 
  BN has two locomotive electrical power purchase agreements, expiring in 1998
and 2001, that currently involve 197 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 1995 minimum commitment
obligation is $53 million. Based on projected locomotive power requirements,
BN's payments in 1995 are expected to be in excess of the minimum. Payments
under the agreements totaled $47 million, $53 million and $56 million in 1994,
1993 and 1992, respectively. 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 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.
 
  BN is party to various claims and lawsuits, some of which are for substantial
amounts. While these claims and actions are being contested, the outcome of
individual matters is not certain. Although actual liability on an aggregate
basis is similarly not determinable with certainty, as of December 31, 1994, BN
believes that any liability resulting from these matters, after taking into
consideration BN's insurance coverages and amounts already provided for, should
not have a material adverse effect on BN's financial position.
 
  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.

  Miscellaneous, net includes losses related to international ventures of $15
million and $4 million in 1994 and 1993, respectively.
 
  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, 1994, BN adopted SFAS No. 112, "Employers' Accounting
for Postemployment Benefits." The cumulative effect, net of $7 million income
tax benefit, of this change in accounting attributable to years prior to 1994,
at the time of adoption, was to decrease 1994 net income by $10 million, or
$.11 per common share.
 
  In 1994, BN adopted SFAS No. 115, "Accounting for Certain Investments in Debt
and Equity Securities." The adoption of this standard had no effect on net
income and no material effect on stockholders' equity.
 
  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 Financial Accounting
Standards Board reached a consensus that origination of service revenue
recognition was not an acceptable accounting 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.

                              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
schedule of Burlington Northern Inc. and Subsidiaries listed in Item 14 of this
Form 10-K. These consolidated financial statements and financial statement
schedule are the responsibility of the Company's management. Our responsibility
is to express an opinion on these consolidated financial statements and
financial statement schedule based on our audits.
 
  We conducted our audits in accordance with 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, 1994 and 1993,
and the consolidated results of their operations and their cash flows for each
of the three years in the period ended December 31, 1994 in conformity with
generally accepted accounting principles. In addition, in our opinion, the
financial statement schedule referred to above, when considered in relation to
the basic financial statements taken as a whole, presents 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 postemployment benefits and investments in
debt and equity securities in 1994, for income taxes in 1993 and for revenue
recognition and postretirement benefits other than pensions in 1992.

(1) Effective January 1, 1994, BN adopted Statement of Financial Accounting
    Standards No. 112, "Employers' Accounting for Postemployment Benefits." The
    cumulative effect, net of $7 million income tax benefit, of this change in
    accounting attributable to years prior to 1994, at the time of adoption,
    was to decrease 1994 net income by $10 million, or $.11 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) Results for the third quarter of 1993 included the effects of the Omnibus
    Budget Reconciliation Act of 1993 (the Act) which was signed into law in
    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, primary, through the date of enactment.
    Results for the third quarter of 1993 also included the effects of the
    severe flooding in the Midwest. BN estimated that 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.

3:00 p.m., New York City time, credit the amounts so received in immediately
available funds to an account designated by the Borrower with the Administrative
Agent or, if a Borrowing shall not occur on such date because any condition
precedent herein specified shall not have been met, return the amounts so
received to the respective Lenders. Competitive Loans shall be made by the
Lender or Lenders whose Competitive Bids therefor are accepted pursuant to
Section 2.03 in the amounts so accepted and Standby Loans shall be made by the
Lenders pro rata in accordance with Section 2.17. Unless the Administrative
Agent shall have received notice from a Lender prior to the date of any
Borrowing (or prior to 12:00 noon on the date of such borrowing, in the case of
an ABR Borrowing) that such

Lender will not make available to the Administrative Agent such Lender's portion
of such Borrowing, the Administrative Agent may assume that such Lender has made
such portion available to the Administrative Agent on the date of such Borrowing
in accordance with this paragraph (c) and the Administrative Agent may, in
reliance upon such assumption, make available to the Borrower on such date a
corresponding amount. If and to the extent that such Lender shall not have made
such portion available to the Administrative Agent, such Lender and the Borrower
severally agree to repay to the Administrative Agent forthwith on demand such
corresponding amount together with interest thereon, for each day from the date
such amount is made available to the Borrower until the date such amount is
repaid to the Administrative Agent at (i) in the case of the Borrower, the
interest rate applicable at the time to the Loans comprising such Borrowing and
(ii) in the case of such Lender, the Federal Funds Effective Rate. If such
Lender shall repay to the Administrative Agent such corresponding amount, such
amount shall constitute such Lender's Loan as part of such Borrowing for
purposes of this Agreement.

          (d)  Notwithstanding any other provision of this Agreement, the 
Borrower shall not be entitled to request any Borrowing if the Interest Period 
requested with respect thereto would end after the Termination Date.

          SECTION 2.03.  Competitive Bid Procedure.  (a)  In order to request
                         --------------------------                          
Competitive Bids, the Borrower shall hand deliver or telecopy (or communicate by
telephone with prompt confirmation by telecopy or in writing) to the CAF Agent
(with a copy to the Administrative Agent) a duly completed Competitive Bid
Request in the form of Exhibit A-1 hereto, to be received by the CAF Agent (and
the Administrative Agent) (i) in the case of a Eurodollar Competitive Borrowing,
not later than 10:30 a.m., New York City time, four Business Days before a
proposed Competitive Borrowing and (ii) in the case of a Fixed Rate Borrowing,
not later than 10:30 a.m., New York City time, one Business Day before a
proposed Competitive Borrowing.  No CD Loan or ABR Loan shall be requested in,
or made pursuant to, a Competitive Bid Request.  A Competitive Bid Request that
does not conform substantially to the format of Exhibit A-1 may be rejected in
the CAF Agent's sole discretion, and the CAF Agent shall promptly notify the
Borrower of such rejection by telecopier (or by telephone with prompt
confirmation by telecopier or in writing).  Such request shall in each case
refer to this Agreement and specify (x) whether the

                                                                              21

Borrowing then being requested is to be a Eurodollar Borrowing or a Fixed Rate
Borrowing, (y) the date of such Borrowing (which shall be a Business Day) and
the aggregate principal amount thereof which shall be in a minimum principal
amount of $5,000,000 and in an integral multiple of $1,000,000, and (z) the
Interest Period with respect thereto (which may not end after the Termination
Date). Promptly after its receipt of a Competitive Bid Request that is not
rejected as aforesaid, the CAF Agent shall invite by telecopier (in the form set
forth in Exhibit A-2 hereto) the Lenders to bid, on the terms and conditions of
this Agreement, to make Competitive Loans pursuant to the Competitive Bid
Request.

          (b)  Each Lender may, in its sole discretion, make one or more 
Competitive Bids to the Borrower responsive to a Competitive Bid Request. Each
Competitive Bid by a Lender must be received by the CAF Agent via telecopier, in
the form of Exhibit A-3 hereto, (i) in the case of a Eurodollar Competitive
Borrowing, not later than 9:30 a.m., New York City time, three Business Days
before a proposed Competitive Borrowing and (ii) in the case of a Fixed Rate
Borrowing, not later than 9:30 a.m., New York City time, on the day of a
proposed Competitive Borrowing. Multiple bids will be accepted by the CAF Agent.
Competitive Bids that do not conform substantially to the format of Exhibit A-3
may be rejected by the CAF Agent, and the CAF Agent shall notify the Lender
making such nonconforming bid of such rejection as soon as practicable. Each
Competitive Bid shall refer to this Agreement and specify (x) the principal
amount (which shall be in a minimum principal amount of $5,000,000 and in an
integral multiple of $1,000,000 and which may equal the entire principal amount
of the Competitive Borrowing requested by the Borrower) of the Competitive Loan
or Loans that the Lender is willing to make to the Borrower, (y) the Competitive
Bid Rate or Rates at which the Lender is prepared to make the Competitive Loan
or Loans and (z) the Interest Period and the last day thereof. If any Lender
shall elect not to make a Competitive Bid, such Lender shall so notify the CAF
Agent by telecopier (I) in the case of Eurodollar Competitive Loans, not later
than 9:30 a.m., New York City time, three Business Days before a proposed
Competitive Borrowing, and (II) in the case of Fixed Rate Loans, not later than
9:30 a.m., New York City time, on the day of a proposed Competitive Borrowing;
provided, however, that failure by any Lender to give such notice shall not

Competitive Borrowing. A Competitive

Bid submitted by a Lender pursuant to this paragraph (b) shall be irrevocable.

          (c)  The CAF Agent shall promptly notify the Borrower by telecopier
(or by telephone promptly confirmed by telecopier) of all the Competitive Bids
made, the Competitive Bid Rate and the principal amount of each Competitive Loan
in respect of which a Competitive Bid was made and the identity of the Lender
that made each bid. The CAF Agent shall send a copy of all Competitive Bids to
the Borrower for its records as soon as practicable after completion of the
bidding process set forth in this Section 2.03.

          (d)  The Borrower may in its sole and absolute discretion, subject 
only to the provisions of this paragraph (d), accept or reject any Competitive
Bid referred to in paragraph (c) above.  The Borrower shall notify the CAF 
Agent by telephone, confirmed by telecopier in the form of a Competitive Bid
Accept/Reject Letter, whether and to what extent it has decided to accept or
reject any of or all the bids referred to in paragraph (c) above, (x) in the
case of a Eurodollar Competitive Borrowing, not later than 10:30 a.m., New York
City time, three Business Days before a proposed Competitive Borrowing, and (y)
in the case of a Fixed Rate Borrowing, not later than 10:30 a.m., New York City
time, on the day of a proposed Competitive Borrowing; provided, however, that
                                                      --------  -------      
          (i) the failure by the Borrower to give such notice shall be deemed 
to be a rejection of all the bids referred to in paragraph (c) above, (ii) the
Borrower shall not accept a bid made at a particular Competitive Bid Rate if the
Borrower has decided to reject a bid made at a lower Competitive Bid Rate, (iii)
the aggregate amount of the Competitive Bids accepted by the Borrower shall not
exceed the principal amount specified in the Competitive Bid Request, (iv) if
the Borrower shall accept a bid or bids made at a particular Competitive Bid
Rate but the amount of such bid or bids shall cause the total amount of bids to
be accepted by the Borrower to exceed the amount specified in the Competitive
Bid Request, then the Borrower shall accept a portion of such bid or bids in an
amount equal to the amount specified in the Competitive Bid Request less the
amount of all other Competitive Bids accepted with respect to such Competitive
Bid Request, which acceptance, in the case of multiple bids at such Competitive
Bid Rate, shall be made pro rata in accordance with the amount of each such bid
at such Competitive Bid Rate, and (v) except pursuant to clause (iv)

                                                                              23

above, no bid shall be accepted for a Competitive Loan unless such Competitive
Loan is in a minimum principal amount of $5,000,000 and an integral multiple of
$1,000,000; provided further, however, that if a Competitive Loan must be in an
            -------- -------  -------
amount less than $5,000,000 because of the provisions of clause (iv) above, such
Competitive Loan may be for a minimum of $1,000,000 or any integral multiple
thereof, and in calculating the pro rata allocation of acceptances of portions
of multiple bids at a particular Competitive Bid Rate pursuant to clause (iv)
above the amounts shall be rounded to integral multiples of $1,000,000 in a
manner which shall be in the discretion of the Borrower. A notice given by the
Borrower pursuant to this paragraph (d) shall be irrevocable.

          (e)  The CAF Agent shall promptly notify each bidding Lender whether 
or not its Competitive Bid has been accepted (and if so, in what amount and at 
what Competitive Bid Rate) by telecopy sent by the CAF Agent, and each 
successful bidder will thereupon become bound, subject to the other applicable 
conditions hereof, to make the Competitive Loan in respect of which its bid has 
been accepted.  The CAF Agent shall also promptly notify the Administrative 
Agent of the Competitive Bids that have been accepted, the amounts thereof and
the Competitive Bid Rates applicable thereto.

          (f)  If the CAF Agent shall become a Lender and shall elect to 
submit a Competitive Bid in its capacity as a Lender, it shall submit such bid 
directly to the Borrower one quarter of an hour earlier than the earliest time 
at which the other Lenders are required to submit their bids to the CAF Agent 
pursuant to paragraph (b) above.  The CAF Agent will in no event disclose the 
terms of any Lender's Competitive Bid to any other Lender; provided that 
                                                           --------
following the acceptance or rejection of Competitive Bids submitted in 
response to any Competitive Bid Request, the CAF Agent may at the request of any
Lender disclose information as to the range of the Competitive Bid Rates at
which Competitive Bids were submitted or accepted.

          (g)  All notices required by this Section 2.03 shall be given in 
accordance with Section 9.01.  Notwithstanding any other provision contained in 
this Section 2.03, the Borrower shall not request any Competitive Bids after the
Termination Date.

          SECTION 2.04.  Standby Borrowing Procedure.  In order to request a 
                         ---------------------------
Standby Borrowing, the Borrower shall hand deliver or telecopy (or communicate 
by telephone with prompt confirmation by telecopy or in writing) to the
Administrative Agent a duly completed Standby Borrowing Request in the form of
Exhibit A-5 (a) in the case of a Eurodollar Standby Borrowing, not later than
11:00 a.m., New York City time, three Business Days before a proposed borrowing,
(b) in the case of a CD Borrowing, not later than 11:00 a.m., New York City
time, two Business Days before a proposed borrowing and (c) in the case of an
ABR Borrowing, not later than 11:00 a.m., New York City time, on the day of a
proposed borrowing. No Fixed Rate Loan shall be requested or made pursuant to a
Standby Borrowing Request. Such notice shall be irrevocable and shall in each
case specify (i) whether the Borrowing then being requested is to be a
Eurodollar Borrowing, a CD Borrowing or an ABR Borrowing; (ii) the date of such
Borrowing (which shall be a Business Day) and the amount thereof which shall be
in a minimum principal amount of $20,000,000 and in an integral multiple of
$1,000,000; and (iii) if such Borrowing is to be a Eurodollar Borrowing or CD
Borrowing, the Interest Period with respect thereto. If no election as to the
Type of Borrowing is specified in any such notice, then the requested Borrowing
shall be an ABR Borrowing. If no Interest Period with respect to any Eurodollar
Borrowing or CD Borrowing is specified in any such notice, then the Borrower
shall be deemed to have selected an Interest Period of one month's duration, in
the case of a Eurodollar Borrowing, or 30 days' duration, in the case of a CD
Borrowing. If the Borrower shall not have given notice in accordance with this
Section 2.04 of its election to refinance a Standby Borrowing prior to the end
of the Interest Period in effect for such Borrowing, then the Borrower shall
(unless such Borrowing is repaid at the end of such Interest Period) be deemed
to have given notice of an election to refinance such Borrowing with an ABR
Borrowing. The Administrative Agent shall promptly advise the Lenders of any
notice given pursuant to this Section 2.04 and of each Lender's portion of the
requested Borrowing.

          SECTION 2.05.  Refinancings.  The Borrower may refinance all or any 
                         ------------
part of any Competitive Borrowing or Standby Borrowing with a Borrowing of the
same or a different Type made pursuant to Section 2.03 or Section 2.04, subject
to the conditions and limitations set forth herein and elsewhere in this
Agreement, including

refinancings of Competitive Borrowings with Standby Borrowings and Standby
Borrowings with Competitive Borrowings. Any Borrowing or part thereof so
refinanced shall be deemed to be repaid in accordance with Section 2.08 with the
proceeds of a new Borrowing hereunder and the proceeds of the new Borrowing, to
the extent they do not exceed the principal amount of the Borrowing being
refinanced, shall not be paid by the Lenders to the Administrative Agent or by
the Administrative Agent to the Borrower pursuant to Section 2.02(c); provided,
                                                                      --------
however, that (i) if the principal amount extended by a Lender in a refinancing
- -------
is greater than the principal amount extended by such Lender in the Borrowing
being refinanced, then such Lender shall pay such difference to the
Administrative Agent for distribution to the Lenders described in (ii) below,
(ii) if the principal amount extended by a Lender in the Borrowing being
refinanced is greater than the principal amount being extended by such Lender in
the refinancing, the Administrative Agent shall return the difference to such
Lender out of amounts received pursuant to (i) above, and (iii) to the extent
any Lender fails to pay the Administrative Agent amounts due from it pursuant to
(i) above, any Loan or portion thereof being refinanced with such amounts shall
not be deemed repaid in accordance with Section 2.08 and shall be payable by the
Borrower.

          SECTION 2.06.  Conversion and Continuation of Standby Borrowings.  The
                         --------------------------------------------------     
Borrower shall have the right at any time upon prior irrevocable notice to the
Administrative Agent (i) not later than 11:00 a.m., New York City time, one
Business Day prior to conversion, to convert any Eurodollar Standby Borrowing or
CD Borrowing into an ABR Borrowing, (ii) not later than 11:00 a.m., New York
City time, two Business Days prior to conversion or continuation, to convert any
Eurodollar Standby Borrowing or ABR Borrowing into a CD Borrowing or to continue
any CD Borrowing as a CD Borrowing for an additional Interest Period, (iii) not
later than 11:00 a.m., New York City time, three Business Days prior to
conversion or continuation, to convert any ABR Borrowing or CD Borrowing into a
Eurodollar Standby Borrowing or to continue any Eurodollar Standby Borrowing as
a Eurodollar Standby Borrowing for an additional Interest Period, (iv) not later
than 11:00 a.m., New York City time, three Business Days prior to conversion, to
convert the Interest Period with respect to any Eurodollar Standby Borrowing to
another permissible Interest Period and (v) not later than 11:00 a.m., New York
City time, two Business Days prior to conversion, to convert the Interest Period

respect to any CD Borrowing to another permissible Interest Period, subject in
each case to the following:

          (a) each conversion or continuation shall be made pro rata among the
     Lenders in accordance with the respective principal amounts of the Loans
     comprising the converted or continued Standby Borrowing;

          (b) if less than all the outstanding principal amount of any Standby
     Borrowing shall be converted or continued, the aggregate principal amount
     of such Standby Borrowing converted or continued shall be an integral
     multiple of $1,000,000 and not less than $20,000,000;

          (c) if any Eurodollar Standby Borrowing or CD Borrowing is converted
     at a time other than the end of the Interest Period applicable thereto, the
     Borrower shall pay, upon demand, any amounts due to the Lenders pursuant to
     Section 2.16;

          (d) any portion of a Standby Borrowing maturing or required to be
     repaid in less than one month may not be converted into or continued as a
     Eurodollar Standby Borrowing;

          (e) any portion of a Standby Borrowing maturing or required to be
     repaid in less than 30 days may not be converted into or continued as a CD
     Borrowing;

          (f) any portion of a Eurodollar Standby Borrowing or CD Borrowing
     which cannot be converted into or continued as a Eurodollar Standby
     Borrowing or a CD Borrowing by reason of clauses (d) and (e) above shall be
     automatically converted at the end of the Interest Period in effect for
     such Borrowing into an ABR Borrowing; and

          (g) no Interest Period may be selected for any Eurodollar Standby
     Borrowing or CD Borrowing that would end later than the Maturity Date.

          Each notice pursuant to this Section 2.06 shall  be by hand delivery
or telecopier (or by telephone with  prompt confirmation by telecopier or in
writing) and irrevocable and shall refer to this Agreement and specify (i) the
identity and amount of the Standby Borrowing that the Borrower requests be
converted or continued,

                                                                              27

(ii) whether such Standby Borrowing is to be converted to or continued as a
Eurodollar Standby Borrowing, a CD Borrowing or an ABR Borrowing, (iii) if such
notice requests a conversion, the date of such conversion (which shall be a
Business Day) and (iv) if such Standby Borrowing is to be converted to or
continued as a Eurodollar Standby Borrowing or CD Borrowing, the Interest Period
with respect thereto.   If no Interest Period is specified in any such notice
with respect to any conversion to or continuation as a Eurodollar Standby
Borrowing or CD Borrowing, the Borrower shall be deemed to have selected an
Interest Period of one month's duration, in the case of a Eurodollar Standby
Borrowing, or 30 days' duration, in the case of a CD Borrowing.  The
Administrative Agent shall advise the other Lenders of any notice given pursuant
to this Section 2.06 and of each Lender's portion of any converted or continued
Standby Borrowing.  If the Borrower shall not have given notice in accordance
with this Section 2.06 to continue any Standby Borrowing into a subsequent
Interest Period (and shall not otherwise have given notice in accordance with
this Section 2.06 to convert such Standby Borrowing), such Standby Borrowing
shall, at the end of the Interest Period applicable thereto (unless repaid
pursuant to the terms hereof), automatically be continued into a new Interest
Period as an ABR Borrowing.

          SECTION 2.07.  Fees.  (a)  The Borrower agrees to pay to each Lender,
                         -----                                                 
through the Administrative Agent, on each March 31, June 30, September 30 and
December 31 and on the Termination Date or, in the event that Standby Loans are
outstanding on the Termination Date, on the Maturity Date, a facility fee (a
"Facility Fee") equal to the Applicable Fee Percentage on the daily average
amount of the Commitment of such Lender, whether used or unused (and whether or
not the conditions set forth in Section 4.01 shall have been satisfied) and,
after the Termination Date, on the daily average amount of the outstanding Loans
of such Lender, during the preceding quarter (or shorter period commencing with
the date hereof, or ending with the Maturity Date or any date on which the
Commitment of such Lender shall be terminated and all outstanding Loans of such
Lender repaid).  All Facility Fees shall be computed on the basis of the actual
number of days elapsed in a year of 365 or 366 days, as appropriate.  The
Facility Fee due to each Lender shall commence to accrue on the date of this
Agreement, and shall cease to accrue on the earlier of the Maturity Date and the
date on which the Commitment of such Lender shall have been terminated and all
outstanding Loans of such Lender repaid.

          (b)  The Borrower agrees to pay the Agents, through the Administrative
Agent, for the Agents' own accounts, the fees set forth in the Engagement Letter
and in the Fee Letter dated April 7, 1994 among the Administrative Agent,
Chemical Securities Inc. and the Borrower (the "Agent Fees") at the times and in
the amounts set forth therein.

          (c)  All Fees shall be paid on the dates due, in immediately available
funds, to the Administrative Agent for distribution, if and as appropriate,
among the Lenders.   Once paid, none of the Fees (other than fees paid in error
and not required to have been paid under the terms of this Agreement) shall be
refundable under any circumstances.

          SECTION 2.08.  Repayment of Loans.  (a)  The Borrower agrees to pay
                         -------------------                                 
the outstanding principal balance of each Competitive Loan on the last day of
the Interest Period applicable to such Competitive Loan and on the Termination
Date.  The Borrower agrees to pay the outstanding principal balance of each
Standby Loan on the last day of the Interest Period applicable to such Standby
Loan, except that each Standby Loan outstanding on the Termination Date shall
become due and payable, and the Borrower agrees to pay the outstanding principal
balance of each such Loan, on the Maturity Date.  Each Loan shall bear interest
from the date of the Borrowing of which such Loan is a part on the outstanding
principal balance thereof as set forth in Section 2.09.

          (b)  Each Lender shall, and is hereby authorized by the Borrower to,
maintain, in accordance with its usual practice, records evidencing the
indebtedness of the Borrower to such Lender hereunder from time to time,
including the amounts and Types of and the Interest Periods applicable to the
Loans made by such Lender from time to time and the amounts of principal and
interest paid to such Lender from time to time in respect of such Loans.

          (c)  The entries made in the records maintained pursuant to paragraph
(b) of this Section 2.08 and in the Register maintained by the Administrative
Agent pursuant to Section 9.04(d) shall be prima facie evidence of the existence
and amounts of the obligations of the Borrower to which such entries relate;

Section 2.10, the Loans comprising each Eurodollar Borrowing shall bear interest
(computed on the basis of the actual number of days elapsed over a year of 360
days) at a rate per annum equal to (i) in the case of each Eurodollar Standby
Loan, the LIBO Rate for the Interest Period in effect for such Borrowing plus
the Applicable Margin from time to time in effect and (ii) in the case of each
Eurodollar Competitive Loan, the LIBO Rate for the Interest Period in effect for
such Borrowing plus the Margin offered by the Lender making such Loan and
accepted by the Borrower pursuant to Section 2.03.

          (b)  Subject to the provisions of Section 2.10, the Loans comprising
each CD Borrowing shall bear interest (computed on the basis of the actual
number of days elapsed over a year of 360 days) at a rate per annum equal to the
Adjusted CD Rate for the Interest Period in effect for such Borrowing plus the
Applicable Margin from time to time in effect.

          (c)  Subject to the provisions of Section 2.10, the Loans comprising
each ABR Borrowing shall bear interest (computed on the basis of the actual
number of days elapsed over a year of 365 or 366 days, as appropriate, when
determined by reference to the Prime Rate and over a year of 360 days at all
other times) at a rate per annum equal to the Alternate Base Rate.

          (d)  Subject to the provisions of Section 2.10, each Fixed Rate Loan
shall bear interest at a rate per annum (computed on the basis of the actual
number of days elapsed over a year of 360 days) equal to the fixed rate of
interest offered by the Lender making such Loan and accepted by the Borrower
pursuant to Section 2.03.

          (e)  Interest on each Loan shall be payable in arrears on each
Interest Payment Date applicable to such Loan except as otherwise provided in
this Agreement.  The applicable LIBO Rate, Adjusted CD Rate or Alternate Base
Rate for each Interest Period or day within an Interest Period, as the case may
be, shall be determined by the Administrative Agent, and such determination
shall be conclusive absent manifest error.  The Administrative Agent

                                                                              30

shall promptly advise the Borrower and each Lender, as appropriate, of such
determination.

          SECTION 2.10.  Default Interest.  If the Borrower shall default in the
                         -----------------                                      
payment of the principal of or interest on any Loan or any other amount becoming
due hereunder, whether by scheduled maturity, notice of prepayment, acceleration
or otherwise, the Borrower shall on demand from time to time from the
Administrative Agent pay interest, to the extent permitted by law, on such
defaulted amount up to (but not including) the date of actual payment (after as
well as before judgment) at a rate per annum (computed on the basis of the
actual number of days elapsed over a year of 365 or 366 days, as appropriate,
when determined by reference to the Prime Rate and over a year of 360 days at
all other times) equal to the Alternate Base Rate plus 1%.

          SECTION 2.11.  Alternate Rate of Interest.  (a)  In the event, and on
                         ---------------------------                           
each occasion, that on the day two Business Days prior to the commencement of
any Interest Period for a Eurodollar Borrowing the Administrative Agent shall
have determined (i) that dollar deposits in the principal amounts of the
Eurodollar Loans comprising such Borrowing are not generally available in the
London interbank market, or (ii) that the rates at which such dollar deposits
are being offered will not adequately and fairly reflect the cost to any Lender
of making or maintaining its Eurodollar Loan during such Interest Period, or
(iii) that reasonable means do not exist for ascertaining the LIBO Rate, the
Administrative Agent shall, as soon as practicable thereafter, give written or
telecopy notice of such determination to the Borrower and the Lenders.  In the
event of any such determination, until the Administrative Agent shall have
advised the Borrower and the Lenders that the circumstances giving rise to such
notice no longer exist, (A) in the event the circumstances referred to in (i) or
(iii) above are applicable, any request by the Borrower for a Eurodollar
Competitive Borrowing pursuant to Section 2.03 shall be of no force and effect
and shall be denied by the CAF Agent and (B) any request by the Borrower for a
Eurodollar Standby Borrowing shall be deemed to be a request for an ABR
Borrowing (x) as to all Lenders, in the event the circumstances referred to in
(i) or (iii) above are applicable, or (y) as to each affected Lender, in the
event only the circumstances referred to in (ii) above are applicable.  In the
event the circumstances referred to in (ii) above are applicable, all payments
and prepayments of principal which would otherwise have been made on account of

                                                                              31

Eurodollar Loans of the affected Lender shall instead be applied to repay the
ABR Loans made by such Lender in lieu of such Eurodollar Loans.  Each
determination by the Administrative Agent hereunder shall be conclusive absent
demonstrable error.

          (b)  In the event, and on each occasion, that on or before the day on
which the Adjusted CD Rate for a CD Borrowing is to be determined the
Administrative Agent shall have determined (i) that such Adjusted CD Rate cannot
be determined for any reason, including the inability of the Administrative
Agent to obtain sufficient bids in accordance with the terms of the definition
of Fixed CD Rate, or (ii) that the Adjusted CD Rate for such CD Borrowing will
not adequately and fairly reflect the cost to any Lender of making or
maintaining its CD Loan during such Interest Period, the Administrative Agent
shall, as soon as practicable thereafter, give written or telecopy notice of
such determination to the Borrower and the Lenders.  In the event of any such
determination, until the Administrative Agent shall have advised the Borrower
and the Lenders that the circumstances giving rise to such notice no longer
exist, any request by the Borrower for a CD Borrowing shall be deemed to be a
request for an ABR Borrowing (i) as to all Lenders, in the event the
circumstances referred to in (i) above are applicable, or (ii) as to each
affected Lender, in the event only the circumstances referred to in (ii) above
are applicable.  In the event the circumstances referred to under (ii) above are
applicable, all payments and prepayments of principal which would otherwise have
been made on account of CD Loans of the affected Lender shall instead be applied
to repay the ABR Loans made by such Lender in lieu of such Loans.  Each
determination by the Administrative Agent hereunder shall be conclusive absent
demonstrable error.

          SECTION 2.12.  Termination and Reduction of Commitments.  (a)  The
                         -----------------------------------------          
Commitments shall be automatically terminated on the Termination Date.

          (b)  Upon at least three Business Days' prior irrevocable written or
telecopy notice to the Administrative Agent, the Borrower may at any time in
whole permanently terminate, or from time to time in part permanently reduce,
the Total Commitment; provided, however, that (i) each partial reduction of the
                      --------  -------                                        
Total Commitment shall be in an integral multiple of $1,000,000 and in a minimum
principal amount of $10,000,000 and (ii) no such termination or

                                                                              32

reduction shall be made which would reduce the Total Commitment to an amount
less than the aggregate outstanding principal amount of the Competitive Loans.

          (c)  Each reduction in the Total Commitment hereunder shall be made
ratably among the Lenders in accordance with their respective Commitments.  The
Borrower shall pay to the Administrative Agent for the account of the Lenders,
on the date of each termination or reduction, the Facility Fees on the amount of
the Commitments so terminated or reduced accrued to but not including the date
of such termination or reduction.

          SECTION 2.13.  Prepayment.  (a)  The Borrower shall have the right at
                         -----------                                           
any time and from time to time to prepay any Standby Borrowing, in whole or in
part, upon giving written or telecopy notice (or telephone notice promptly
confirmed by written or telecopy notice) to the Administrative Agent:  (i)
before 12:00 noon, New York City time, three Business Days prior to prepayment,
in the case of Eurodollar Loans, (ii) before 12:00 noon, New York City time, two
Business Days prior to prepayment, in the case of CD Loans, and (iii) before
12:00 noon, New York City time, one Business Day prior to prepayment, in the
case of ABR Loans; provided, however, that each partial prepayment shall be in
                   --------  -------                                          
an amount which is an integral multiple of $1,000,000 and not less than
$10,000,000.  The Borrower shall not have the right to prepay any Competitive
Borrowing.

          (b)  On the date of any termination or reduction of the Commitments
pursuant to Section 2.12, the Borrower shall pay or prepay so much of the
Standby Borrowings as shall be necessary in order that the aggregate principal
amount of the Competitive Loans and Standby Loans outstanding will not exceed
the Total Commitment after giving effect to such termination or reduction.

          (c)  Each notice of prepayment shall specify the prepayment date and
the principal amount of each Borrowing (or portion thereof) to be prepaid, shall
be irrevocable and shall commit the Borrower to prepay such Borrowing (or
portion thereof) by the amount stated therein on the date stated therein.  All
prepayments under this Section 2.13 shall be subject to Section 2.16 but
otherwise without premium or penalty.  All prepayments under this Section 2.13
shall be accompanied by accrued interest on the principal amount being prepaid
to the date of payment.

          SECTION 2.14.  Reserve Requirements; Change in Circumstances.  (a)
                         ----------------------------------------------      
Notwithstanding any other provision herein, if after the date of this Agreement
any change in applicable law or regulation or in the interpretation or
administration thereof by any Governmental Authority charged with the
interpretation or administration thereof (whether or not having the force of
law) shall change the basis of taxation of payments to any Lender of the
principal of or interest on any Eurodollar Loan, CD Loan or Fixed Rate Loan made
by such Lender or any Fees or other amounts payable hereunder (other than
changes in respect of taxes imposed on the overall net income of such Lender by
the jurisdiction in which such Lender has its principal office or by any
political subdivision or taxing authority therein), or shall impose, modify or
deem applicable any reserve, special deposit or similar requirement against
assets of, deposits with or for the account of or credit extended by such Lender
(except any such reserve requirement which is reflected in the Adjusted CD
Rate), or shall impose on such Lender or the London interbank market any other
condition affecting this Agreement or any Eurodollar Loan, CD Loan or Fixed Rate
Loan made by such Lender, and the result of any of the foregoing shall be to
increase the cost to such Lender of making or maintaining any Eurodollar Loan,
CD Loan or Fixed Rate Loan or to reduce the amount of any sum received or
receivable by such Lender hereunder (whether of principal, interest or
otherwise) by an amount deemed by such Lender to be material, then the Borrower
will pay to such Lender upon demand such additional amount or amounts as will
compensate such Lender for such additional costs incurred or reduction suffered.
Notwithstanding the foregoing, no Lender shall be entitled to request
compensation under this paragraph with respect to any Competitive Loan if it
shall have been aware of the change giving rise to such request at the time of
submission of the Competitive Bid pursuant to which such Competitive Loan shall
have been made.

          (b)  If any Lender shall have determined that the applicability of any
law, rule, regulation or guideline adopted pursuant to or arising out of the
July 1988 report of the Basle Committee on Banking Regulations and Supervisory
Practices entitled "International Convergence of Capital Measurement and Capital
Standards", or the adoption after the date hereof of any other law, rule,
regulation or guideline regarding capital adequacy, or any change in any of the
foregoing or in the interpretation or administration of any of the foregoing by
any Governmental Authority, central bank or comparable agency charged with the

[6700-070(A)RAF/A08A.WPF/30D/4674W]

                                                                              34

interpretation or administration thereof, or compliance by any Lender (or any
lending office of such Lender) or any Lender's holding company with any request
or directive regarding capital adequacy (whether or not having the force of law)
of any such authority, central bank or comparable agency, has or would have the
effect of reducing the rate of return on such Lender's capital or on the capital
of such Lender's holding company, if any, as a consequence of this Agreement or
the Loans made by such Lender pursuant hereto to a level below that which such
Lender or such Lender's holding company could have achieved but for such
applicability, adoption, change or compliance (taking into consideration such
Lender's policies and the policies of such Lender's holding company with respect
to capital adequacy) by an amount deemed by such Lender to be material, then
from time to time the Borrower shall pay to such Lender such additional amount
or amounts as will compensate such Lender or such Lender's holding company for
any such reduction suffered.  It is acknowledged that the Facility Fee provided
for in this Agreement has been determined on the understanding that the Lenders
will not be required to maintain capital against their Commitments under
currently applicable laws, regulations and regulatory guidelines.  In the event
the Lenders shall be advised by regulatory authorities or shall otherwise
determine on the basis of pronouncements of regulatory authorities that such
understanding is incorrect, it is agreed that the Lenders will be entitled to
make claims under this paragraph based upon prevailing market requirements for
commitments under comparable credit facilities against which capital is required
to be maintained.

          (c)  A certificate of a Lender setting forth such amount or amounts as
shall be necessary to compensate such Lender as specified in paragraph (a) or
(b) above, as the case may be, shall be delivered to the Borrower and shall be
conclusive absent demonstrable error.  The Borrower shall pay each Lender the
amount shown as due on any such certificate delivered by it within 10 days after
the receipt of the same.

          (d)  Except as provided in this paragraph, failure on the part of any
Lender to demand compensation for any increased costs or reduction in amounts
received or receivable or reduction in return on capital with respect to any
period shall not constitute a waiver of such Lender's right to demand
compensation with respect to such period or any other period.  The protection of
this Section shall be

                                                                              35

available to each Lender regardless of any possible contention of the invalidity
or inapplicability of the law, rule, regulation, guideline or other change or
condition which shall have occurred or been imposed.  No Lender shall be
entitled to compensation under this Section 2.14 for any costs incurred or
reductions suffered with respect to any date unless it shall have notified the
Borrower that it will demand compensation for such costs or reductions under
paragraph (c) above not more than 60 days after the later of (i) such date and
(ii) the date on which it shall have become aware of such costs or reductions.

          SECTION 2.15.  Change in Legality.  (a)  Notwithstanding any other
                         -------------------                                 
provision herein, if any change in any law or regulation or in the
interpretation thereof by any governmental authority charged with the
administration or interpretation thereof shall make it unlawful for any Lender
to make or maintain any Eurodollar Loan or to give effect to its obligations as
contemplated hereby with respect to any Eurodollar Loan, then, by written notice
to the Borrower and to the Administrative Agent, such Lender may:

          (i) declare that Eurodollar Loans will not thereafter be made by such
     Lender hereunder, whereupon such Lender shall not submit a Competitive Bid
     in response to a request for Eurodollar Competitive Loans and any request
     by the Borrower for a Eurodollar Standby Borrowing shall, as to such Lender
     only, be deemed a request for an ABR Borrowing unless such declaration
     shall be subsequently withdrawn (and such Lender agrees to withdraw any
     such declaration if legally permissible); and

          (ii) require that all outstanding Eurodollar Loans made by it be
     converted to ABR Loans (or in the case of a Eurodollar Competitive Loan, a
     Loan bearing interest at a rate equal to the Alternate Base Rate), as of
     the effective date of such notice as provided in paragraph (b) below.

In the event any Lender shall exercise its rights under (i) or (ii) above, all
payments and prepayments of principal which would otherwise have been applied to
repay the Eurodollar Loans that would have been made by such Lender or the
converted Eurodollar Loans of such Lender shall instead be applied to repay the
ABR Loans made by such Lender in lieu of, or resulting from the conversion of,
such Eurodollar Loans.

          (b)  For purposes of this Section 2.15, a notice to the Borrower by
any Lender shall be effective as to each Eurodollar Loan, if lawful, on the last
day of the Interest Period currently applicable to such Eurodollar Loan; in all
other cases such notice shall be effective on the date of receipt by the
Borrower.

          SECTION 2.16.  Indemnity.  The Borrower shall indemnify each Lender
                         ----------                                          
against any actual loss or expense which such Lender may sustain or incur as a
consequence of (a) any failure by the Borrower to fulfill on the date of any
borrowing hereunder the applicable conditions set forth in Article IV, (b) any
failure by the Borrower to borrow or to refinance, convert or continue any Loan
hereunder after irrevocable notice of such borrowing, refinancing or
continuation has been given pursuant to Section 2.03, 2.04 or 2.06, (c) any
payment, prepayment or conversion of a Eurodollar Loan, CD Loan or Fixed Rate
Loan required by any other provision of this Agreement or otherwise made or
deemed made, and any assignment of a Loan pursuant to  Section 2.21, on a date
other than the last day of the Interest Period applicable thereto, (d) any
default in payment or prepayment of the principal amount of any Loan or any part
thereof or interest accrued thereon, as and when due and payable (at the due
date thereof, whether by scheduled maturity, acceleration, irrevocable notice of
prepayment or otherwise) or (e) the occurrence of any Event of Default,
including, in each such case, any actual loss or reasonable expense sustained or
incurred or to be sustained or incurred in liquidating or employing deposits
from third parties acquired to effect or maintain such Loan or any part thereof
as a Eurodollar Loan, CD Loan or Fixed Rate Loan.   Such loss or reasonable
expense shall include an amount equal to the excess, if any, as reasonably
determined by such Lender, of (i) its cost of obtaining the funds for the Loan
being paid, prepaid, converted, not borrowed, not refinanced, not converted, not
continued or assigned (assumed to be the LIBO Rate or Adjusted CD Rate or, in
the case of a Fixed Rate Loan, the fixed rate of interest applicable thereto)
for the period from the date of such payment, prepayment, failure to borrow,
failure to refinance, failure to convert, failure to continue or assignment to
the last day of the Interest Period for such Loan (or, in the case of a failure
to borrow, refinance, convert or continue, the Interest Period for such Loan
which would have commenced on the date of such failure) over (ii) the amount of
interest (as reasonably determined by such Lender) that would be realized by
such Lender in

                                                                              37

reemploying the funds so paid, prepaid, not borrowed, not refinanced, not
converted, not continued or assigned for such period or Interest Period, as the
case may be.  A certificate of any Lender setting forth any amount or amounts
which such Lender is entitled to receive pursuant to this Section shall be
delivered to the Borrower and shall be conclusive absent demonstrable error.

          SECTION 2.17.  Pro Rata Treatment.  Except as required under Section
                         -------------------                                  
2.15, each Standby Borrowing, each payment or prepayment of principal of any
Standby Borrowing, each payment of interest on the Standby Loans, each payment
of the Facility Fees, each reduction of the Commitments and each refinancing of
any Borrowing with a Standby Borrowing of any Type, shall be allocated pro rata
among the Lenders in accordance with their respective Commitments (or, if such
Commitments shall have expired or been terminated, in accordance with the
respective principal amounts of their outstanding Standby Loans).  Each payment
of principal of any Competitive Borrowing shall be allocated pro rata among the
Lenders participating in such Borrowing in accordance with the respective
principal amounts of their outstanding Competitive Loans comprising such
Borrowing.  Each payment of interest on any Competitive Borrowing shall be
allocated pro rata among the Lenders participating in such Borrowing in
accordance with the respective amounts of accrued and unpaid interest on their
outstanding Competitive Loans comprising such Borrowing.  For purposes of
determining (i) the aggregate available Commitments of the Lenders at any time
and (ii) the available Commitment of each Lender, each outstanding Competitive
Borrowing shall be deemed to have utilized the Commitments of the Lenders
(including those Lenders which shall not have made Loans as part of such
Competitive Borrowing) pro rata in accordance with such respective Commitments.
Each Lender agrees that in computing such Lender's portion of any Borrowing to
be made hereunder, the Administrative Agent may, in its discretion, round each
Lender's percentage of such Borrowing to the next higher or lower whole dollar
amount.

          SECTION 2.18.  Sharing of Setoffs.  Each Lender agrees that if it
                         -------------------                               
shall, through the exercise of a right of banker's lien, setoff or counterclaim
against the Borrower, or pursuant to a secured claim under Section 506 of Title
11 of the United States Code or other security or interest arising from, or in
lieu of, such secured claim, received by such Lender under any applicable
bankruptcy, insolvency or other similar law or otherwise, or by any other means,

obtain payment (voluntary or involuntary) from the Borrower or its assets in
respect of any Standby Loan or Loans as a result of which the unpaid principal
portion of its Standby Loans shall be proportionately less than the unpaid
principal portion of the Standby Loans of any other Lender, it shall be deemed
simultaneously to have purchased from such other Lender at face value, and shall
promptly pay to such other Lender the purchase price for, a participation in the
Standby Loans of such other Lender, so that the aggregate unpaid principal
amount of the Standby Loans and participations in the Standby Loans held by each
Lender shall be in the same proportion to the aggregate unpaid principal amount
of all Standby Loans then outstanding as the principal amount of its Standby
Loans prior to such exercise of banker's lien, setoff or counterclaim or other
event was to the principal amount of all Standby Loans outstanding prior to such
exercise of banker's lien, setoff or counterclaim or other event; provided,
                                                                  -------- 
however, that, if any such purchase or purchases or adjustments shall be made
- -------                                                                      
pursuant to this Section 2.18 and the payment giving rise thereto shall
thereafter be recovered, such purchase or purchases or adjustments shall be
rescinded to the extent of such recovery and the purchase price or prices or
adjustment restored without interest.  The Borrower expressly consents to the
foregoing arrangements and agrees that any Lender holding a participation in a
Standby Loan deemed to have been so purchased may exercise any and all rights of
banker's lien, setoff or counterclaim with respect to any and all moneys owing
by the Borrower to such Lender by reason thereof as fully as if such Lender had
made a Standby Loan directly to the Borrower in the amount of such
participation.

          SECTION 2.19.  Payments.  (a)  The Borrower shall make each payment
                         ---------

amounts) hereunder and under each other Loan Document not later than 12:00 noon,
New York City time, on the date when due in dollars to the Administrative Agent
at its offices at 712 Main Street, Houston, Texas, in immediately available
funds.

          (b)  Whenever any payment (including principal of or interest on any
Borrowing or any Fees or other amounts) hereunder or under any other Loan
Document shall become due, or otherwise would occur, on a day that is not a
Business Day, such payment may be made on the next succeeding Business Day, and
such extension of time shall in such case

be included in the computation of interest or Fees, if applicable.

          SECTION 2.20.  Taxes.  (a)  Any and all payments by the Borrower
                         ------                                           
hereunder shall be made, in accordance with Section 2.19, free and clear of and
without deduction for any and all present or future taxes, levies, imposts,
deductions, charges or withholdings, and all liabilities with respect thereto,
                                                                              
excluding taxes, levies, imposts, deductions, charges and withholdings imposed
- ---------                                                                     
on the Administrative Agent's or any Lender's (or any transferee's or
assignee's, including a participation holder's (any such entity a "Transferee"))
net income and franchise, capital or license taxes imposed on the Administrative
Agent or any Lender (or Transferee) by the United States or any jurisdiction
under the laws of which it is organized, domiciled, resident or doing business
(other than doing business as a result of its participation in the transactions
contemplated by the Loan Documents) or any political subdivision thereof (all
such nonexcluded taxes, levies, imposts, deductions, charges, withholdings and
liabilities being hereinafter referred to as "Taxes").  If the Borrower shall be
required by law to deduct any Taxes from or in respect of any sum payable
hereunder to the Lenders (or any Transferee) or the Administrative Agent, (i)
the sum payable shall be increased by the amount necessary so that after making
all required deductions (including deductions applicable to additional sums
payable under this Section 2.20) such Lender (or Transferee) or the
Administrative Agent (as the case may be) shall receive an amount equal to the
sum it would have received had no such deductions been made, (ii) the Borrower
(or the Administrative Agent, as applicable) shall make such deductions at the
applicable rate and (iii) the Borrower (or the Administrative Agent, as
applicable) shall pay the full amount deducted to the relevant taxing authority
or other Governmental Authority in accordance with applicable law.

          (b)  In addition, the Borrower agrees to pay any present or future
stamp or documentary taxes or any other excise or property taxes, charges or
similar levies which arise from any payment made hereunder or from the
execution, delivery or registration of, or otherwise with respect to, this
Agreement or any other Loan Document (hereinafter referred to as "Other Taxes").

          (c)  The Borrower will indemnify each Lender (or Transferee) and the
Administrative Agent for the full amount

                                                                              40

of Taxes and Other Taxes (including any Taxes or Other Taxes imposed by any
jurisdiction on amounts payable under this Section 2.20) paid by such Lender (or
Transferee) or the Administrative Agent, as the case may be, and any liability
(including penalties, interest and expenses) arising therefrom or with respect
thereto, whether or not such Taxes or Other Taxes were correctly or legally
asserted by the relevant taxing authority or other Governmental Authority.  Such
indemnification shall be made within 30 days after the date any Lender (or
Transferee) or the Administrative Agent, as the case may be, makes written
demand therefor; provided, however, that the Borrower shall not have any
                 --------  -------                                      
obligation to indemnify the Administrative Agent or any Lender (or Transferee)
for interest and penalties that are imposed on the Administrative Agent or such
Lender (or Transferee) with respect to the period after the expiration of the
Notice Period with respect to any Tax if such Administrative Agent or such
Lender fails to give written notice to the Borrower within 45 days of its
receipt of any written assertion by the relevant taxing authority or other
Governmental Authority that such Tax is due with respect to the transactions
contemplated by the Loan Documents (such 45 day period being the "Notice Period"
referred to above).  If a Lender (or Transferee) or the Administrative Agent
shall become aware that it is entitled to receive a refund (or a credit against
taxes not indemnifiable hereunder) in respect of Taxes or Other Taxes, it shall
promptly notify the Borrower of the availability of such refund (or credit) and
shall, within 30 days after receipt of a request by the Borrower, apply for such
refund at the Borrower's expense.  If any Lender (or Transferee) or the
Administrative Agent receives a refund (or a credit against taxes not
indemnifiable hereunder) in respect of any Taxes or Other Taxes for which such
Lender (or Transferee) or the Administrative Agent has received payment from the
Borrower hereunder it shall promptly notify the Borrower of such refund (or
credit) and shall, within 30 days after receipt of a request by the Borrower (or
promptly upon receipt, if the Borrower has requested application for such refund
(or credit) pursuant hereto), repay such refund (or credit) to the Borrower, net
of all out-of-pocket expenses (including taxes not indemnifiable hereunder, to
the extent that no deduction or credit has previously been claimed and utilized
in connection therewith by such Lender) of such Lender but including interest
received from a taxing authority or other Governmental Authority and fairly
attributable to such refund; provided that the Borrower, upon the request of
                             --------                                       
such Lender (or Transferee) or the Administrative Agent, agrees

                                                                              41

to return such refund (plus penalties, interest or other charges) to such Lender
(or Transferee) or the Administrative Agent in the event such Lender (or
Transferee) or the Administrative Agent is required to repay such refund.  Each
of the Administrative Agent, each Lender and each Transferee, with respect to
itself, agrees to indemnify and hold harmless the Borrower (and, in the case of
each Lender and each Transferee, to indemnify and hold harmless the
Administrative Agent) from any taxes, penalties, interest and other expenses,
costs and losses incurred or payable by the Borrower (or the Administrative
Agent, as applicable) as a result of the failure of the Borrower to comply with
clauses (ii) and (iii) of Section 2.20(a) in reliance on any form or certificate
provided to it by such person pursuant to Section 2.20(f).

          (d)  Within 30 days after the date of any payment of Taxes or Other
Taxes withheld by the Borrower in respect of any payment to any Lender (or
Transferee) or the Administrative Agent, the Borrower will furnish to the
Administrative Agent, at its address referred to in Section 9.01, the original
or a certified copy of a receipt evidencing payment thereof or other customary
evidence of such payment.

          (e)  Without prejudice to the survival of any other agreement
contained herein, the agreements and obligations contained in this Section 2.20
shall survive the payment in full of the principal of and interest on all Loans
made hereunder.

          (f)  On or prior to the Closing Date (in the case of any Lender and
the Administrative Agent) and on or prior to the date any Transferee becomes a
Transferee hereunder (in the case of any Transferee), and, upon written request
of the Borrower or the Administrative Agent, on or prior to the immediately
following due date of any payment by the Borrower hereunder, each Lender (or
Transferee) which is organized outside the United States shall deliver to the
Borrower such certificates, documents or other evidence, as required by the Code
or Treasury Regulations issued pursuant thereto, including Internal Revenue
Service Form 1001 or Form 4224 and any other certificate or statement of
exemption required by Treasury Regulation Section 1.1441-1(a) or Section 1.1441-
6(c) or any subsequent version thereof, properly completed and duly executed by
such Lender (or Transferee) establishing that such payment is (i) not subject to
withholding under the Code because such payment

                                                                              42

is effectively connected with the conduct by such Lender (or Transferee) of a
trade or business in the United States or (ii) totally exempt from United States
tax under a provision of an applicable tax treaty.  Unless the Borrower and the
Administrative Agent have received forms or other documents satisfactory to them
indicating that payments hereunder and in respect of the Loans are not subject
to United States withholding tax the Borrower or the Administrative Agent shall
withhold taxes from such payments at the applicable statutory rate in the case
of payments to or for any Lender (or Transferee) organized under the laws of a
jurisdiction outside the United States.

          (g)  The Borrower shall not be required to pay any additional amounts
to any Lender (or Transferee) in respect of United States withholding tax
pursuant to paragraph (a) above except to the extent such United States
withholding tax (a) results from (i) a change in applicable law, regulation or
official interpretation thereof or (ii) an amendment, modification or revocation
of any applicable tax treaty or a change in official position regarding the
application or interpretation thereof, in each case after the Closing Date (and,
in the case of a Transferee, after the date of assignment or transfer) or (b) in
the case of a Transferee, is imposed at a rate that does not exceed the rate
(determined at the time of transfer or assignment) of United States withholding
tax with respect to which the Borrower was required to pay to such Transferee's
transferor or assignor.

          SECTION 2.21.  Termination or Assignment of Commitments Under Certain
                         ---------------------------- -------------------------
Circumstances.  (a)  Any Lender (or Transferee) claiming any additional amounts
- --------------                                                                 
payable pursuant to Section 2.14 or Section 2.20 shall use reasonable efforts
(consistent with legal and regulatory restrictions) to file any certificate or
document requested by the Borrower or to change the jurisdiction of its
applicable lending office if the making of such a filing or change would avoid
the need for or reduce the amount of any such additional amounts which may
thereafter accrue and would not, in the sole determination of such Lender, be
otherwise disadvantageous to such Lender (or Transferee).

          (b)  In the event that any Lender shall have delivered a notice or
certificate pursuant to Section 2.14 or 2.15, or the Borrower shall be required
to make additional payments to any Lender under Section 2.20, the Borrower shall
have the right, at its own expense, upon

notice to such Lender and the Administrative Agent, (a) to terminate the
Commitment of such Lender or (b) to require such Lender to transfer and assign
without recourse (in accordance with and subject to the restrictions contained
in Section 9.04) all its interests, rights and obligations under this Agreement
to another financial institution acceptable to the Administrative Agent which
shall assume such obligations; provided that (i) no such termination or
                               --------                                
assignment shall conflict with any law, rule or regulation or order of any
Governmental Authority and (ii) the Borrower or the assignee, as the case may
be, shall pay to the affected Lender in immediately available funds on the date
of such termination or assignment the principal of and interest accrued to the
date of payment on the Loans made by it hereunder and all other amounts accrued
for its account or owed to it hereunder.


ARTICLE III.  REPRESENTATIONS AND WARRANTIES

          The Borrower represents and warrants to each of the Lenders that:

          (a)  The Borrower is a corporation duly incorporated, validly existing
     and in good standing under the laws of the State of Delaware.  The Borrower
     possesses all corporate powers and all other authorizations and licenses
     necessary to engage in its business and operations as now conducted, the
     failure to obtain or maintain which would result in a Material Adverse
     Effect.

          (b)  The execution, delivery and performance by the Borrower of this
     Agreement are within the Borrower's corporate powers, have been duly
     authorized by all necessary corporate action, and do not contravene (i) the
     Borrower's certificate of incorporation or by-laws or (ii) any law or
     contractual restriction binding on or affecting the Borrower.

          (c)  There is no authorization or approval or other action by, and no
     notice to or filing with, any Governmental Authority (including, without
     limitation, the ICC) required for the due execution, delivery and
     performance by the Borrower of this Agreement which has not been obtained
     or made, as the case may be.

[6700-070(A)RAF/A08A.WPF/30D/4674W]
<PAGE>
 
                                                                              44

          (d)  This Agreement is the legal, valid and binding obligation of the
     Borrower enforceable against the Borrower in accordance with its terms
     except as enforceability may be limited by applicable bankruptcy,
     insolvency, moratorium or other similar laws affecting the enforcement of
     creditors' rights generally or by the applicability of equitable
     principles.

          (e)   The consolidated balance sheet of the Borrower and its
     consolidated Subsidiaries as at December 31, 1993, and the related
     consolidated statements of income and cash flows for the fiscal year then
     ended, copies of which have been furnished to each Lender, fairly present
     the consolidated financial condition of the Borrower and such Subsidiaries
     as at such date and the results of their operations for the period ended on
     such date, all in accordance with GAAP consistently applied, and since
     December 31, 1993, there has been no material adverse change in such
     condition or operations.

          (f)  There is no pending or threatened action or proceeding against or
     involving the Borrower before any Governmental Authority or arbitrator
     which has a reasonable probability (taking into account the exhaustion of
     all appeals) of resulting in a Material Adverse Effect.

          (g)  The Borrower has duly paid and discharged all taxes, assessments
     and governmental charges upon it or against its properties now due and
     payable, the failure to pay which would result in a Material Adverse Effect
     unless and to the extent only that the same are being contested in good
     faith and by appropriate proceedings by the Borrower.

          (h)  The Borrower has good title to its properties and assets except
     for (i) existing or future liens, security interests, mortgages,
     conditional sales arrangements and other encumbrances (including, without
     limitation, reversionary title interests) either securing Debt or other
     liabilities of the Borrower or any of its Subsidiaries or which the
     Borrower in its reasonable business judgment determines would not be
     reasonably expected to materially interfere with the railroad business or
     railroad operations of the Borrower and its Subsidiaries as conducted from
     time to time and (ii) irregularities therein which do not

<PAGE>
 
                                                                              45

     materially interfere with the business or operations of the Borrower and
     its Subsidiaries as conducted from time to time.

          (i)  No Termination Event has occurred or is reasonably expected to
     occur with respect to any Plan which, with the giving of notice or lapse of
     time, or both, would constitute an Event of Default under paragraph (g) of
     Article VII.

          (j)  The statement of assets and liabilities of each Plan covered by
     the report of Coopers & Lybrand referred to below as of December 31, 1993,
     and the statements of changes in fund balance and in financial position, or
     the statement of changes in net assets available for plan benefits, for the
     plan year then ended, reported on by Coopers & Lybrand, copies of which
     have been furnished to the Administrative Agent, fairly present the
     financial condition of such Plan as at such date and the results of
     operations of such Plan for the plan year ended on such date.

          (k)  Neither the Borrower nor any ERISA Affiliate has incurred, or is
     reasonably expected to incur, any Withdrawal Liability to any Multiemployer
     Plan which, when aggregated with all other amounts required to be paid to
     Multiemployer Plans in connection with Withdrawal Liability (as of the date
     of determination), exceeds $50,000,000.

          (l)  Neither the Borrower nor any ERISA Affiliate has received any
     notification that any Multiemployer Plan is in reorganization or has been
     terminated, within the meaning of Title IV of ERISA, and no Multiemployer
     Plan is reasonably expected to be in reorganization or to be terminated
     within the meaning of Title IV of ERISA, the effect of which reorganization
     or termination would be the occurrence of an Event of Default under
     paragraph (i) of Article VII.

          (m)  Neither the Borrower nor any of its Subsidiaries is engaged
     principally, or as one of its important activities, in the business of
     extending credit for the purpose of purchasing or carrying Margin Stock.
     No part of the proceeds of any Loan will be used, whether directly or
     indirectly, and whether immediately, incidentally or ultimately, for any

                                                                              46

     purpose which entails a violation of, or which is inconsistent with, the
     provisions of the Regulations of the Board, including Regulation G, U or X.

          (n)  Neither the Borrower nor any Subsidiary is (i) an "investment
     company" as defined in, or subject to regulation under, the Investment
     Company Act of 1940 or (ii) a "holding company" as defined in, or subject
     to regulation under, the Public Utility Holding Company Act of 1935.

          (o)  The Borrower will use the proceeds of the Loans only for the
     purposes specified in the preamble to this Agreement.

          (p)  Neither the Borrower nor any of its Subsidiaries is, to the best
     of its knowledge, in violation of any law or statute, or in default with
     respect to any judgment, writ, injunction, decree, rule or regulation of
     any court or governmental agency or instrumentality, where such violation
     or default would result in a Material Adverse Effect.

          (q)  On the Closing Date, there has been no material adverse change in
     or affecting the business, assets, liabilities or operations of the
     Borrower or in the condition (financial or otherwise) or prospects of the
     Borrower from those shown in the information furnished to the Lenders prior
     to the date hereof.

          (r) To the best knowledge of the Borrower, on the Closing Date all
     insurable properties of the Borrower and each Subsidiary are adequately
     insured as part of an insurance program including risk retention and self
     insurance by financially sound and reputable insurers to such extent and
     against such risks and liabilities (including liability under Federal,
     state, local and other statutes and regulations relating to the environment
     or to employee health and safety) as is customary with companies similarly
     situated and in the same or similar businesses.

Texas Commerce Bank National Association and Chemical Bank Agency Services
Corporation are hereby appointed to act as Administrative Agent and CAF Agent,
respectively, on behalf of the Lenders.  Each of the Lenders hereby irrevocably
authorizes the Agents to take such actions on behalf of such Lender and to
exercise such powers as are specifically delegated to the Agents by the terms
and provisions hereof and of the other Loan Documents, together with such
actions and powers as are reasonably incidental thereto.  The Administrative
Agent is hereby expressly authorized by the Lenders, without hereby limiting any
implied authority, (a) to receive on behalf of the Lenders all payments of
principal of and interest on the Loans and all other amounts due to the Lenders
hereunder, and promptly to distribute to each Lender its proper share of each
payment so received; (b) to give notice on behalf of each of the Lenders to the
Borrower of any Event of Default specified in this Agreement of which the
Administrative Agent has actual knowledge acquired in connection with its agency
hereunder; and (c) to distribute to each Lender copies of all notices, financial
statements and other materials delivered by the Borrower pursuant to this

any action taken or omitted by any of them except for its, his or her own gross
negligence or wilful misconduct, or be responsible for any warranty or
representation herein or the contents of any document delivered in connection
herewith, or be required to ascertain or to make any inquiry concerning the
performance or observance by the Borrower of any of the terms, conditions,
covenants or agreements contained in any Loan Document other than those
expressly provided for herein.  The Agents shall not be responsible to the
Lenders for the due execution, genuineness, validity, enforceability or
effectiveness (other than against the Agents) of this Agreement or any other
Loan Documents or other instruments or agreements.  The Agents shall in all
cases be fully protected in acting, or refraining from acting, in accordance
with written instructions signed by the Required Lenders and, except as
otherwise specifically provided herein, such instructions and any action or
inaction pursuant thereto shall be binding on all the Lenders.   Each Agent
shall, in the absence of knowledge to the contrary, be entitled to rely on any
instrument or document believed by it in good faith to be genuine and correct
and to have been signed or sent by the proper person or persons.  Neither the
Agents nor any of their directors, officers, employees or agents shall have any
responsibility to the Borrower on account of the failure of or delay in
performance or breach by any Lender of any of its obligations hereunder or to
any Lender on account of the failure of or delay in performance or breach by any
other Lender or the Borrower of any of their respective obligations hereunder or
under any other Loan Document or in connection herewith or therewith.  The
Agents may execute any and all duties hereunder by or through agents or
employees and shall be entitled to rely upon the advice of legal counsel
reasonably selected by them with respect to all matters arising hereunder and
shall not be liable for any action taken or suffered in good faith by it in
accordance with the advice of such counsel.

          The Lenders hereby acknowledge that the Agents shall be under no duty
to take any discretionary action permitted to be taken by it pursuant to the
provisions of this Agreement unless it shall be requested in writing to do so by
the Required Lenders.

          Subject to the appointment and acceptance of a successor Agent as
provided below, any Agent may resign at any time by notifying the Lenders and
the Borrower.  Upon any such resignation, the Required Lenders shall have the

right to appoint a successor.  If no successor shall have been so appointed by
the Required Lenders and shall have accepted such appointment within 30 days
after the retiring Agent gives notice of its resignation, then the retiring
Agent may, on behalf of the Lenders, appoint a successor Agent which shall be a
bank with an office in the United States, having a combined capital and surplus
of at least $50,000,000 or an Affiliate of any such bank.  Upon the acceptance
of any appointment as Agent hereunder by a successor bank, such successor shall
succeed to and become vested with all the rights, powers, privileges and duties
of the retiring Agent and the retiring Agent shall be discharged from its
duties and obligations hereunder.  After any Agent's resignation hereunder, the
provisions of this Article and Section 9.05 shall continue in effect for its
benefit in respect of any actions taken or omitted to be taken by it while it
was acting as Agent.

          With respect to the Loans made by them hereunder, the Agents in their
individual capacity and not as Agents shall have the same rights and powers as
any other Lender and may exercise the same as though they were not the Agents,
and the Agents and their Affiliates may accept deposits from, lend money to and
generally engage in any kind of business with the Borrower or any Subsidiary or
other Affiliate thereof as if they were not the Agents.

          Each Lender agrees (i) to reimburse the Agents, on demand, in the
amount of its pro rata share (based on its Commitment hereunder) of any
reasonable expenses incurred for the benefit of the Lenders by the Agents,
including counsel fees and compensation of agents and employees paid for
services rendered on behalf of the Lenders, which shall not have been reimbursed
by the Borrower and (ii) to indemnify and hold harmless the Agents and any of
its directors, officers, employees or agents, on demand, in the amount of such
pro rata share, from and against any and all liabilities, taxes, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind or nature whatsoever which may be imposed on, incurred
by or asserted against them in their capacity as the Agents or any of them in
any way relating to or arising out of this Agreement or any other Loan Document
or any action taken or omitted by it or any of them under this Agreement or any
other Loan Document, to the extent the same shall not have been reimbursed by
the Borrower; provided that no Lender shall be liable to the Agents for any

penalties, actions, judgments, suits, costs, expenses or disbursements resulting
from the gross negligence or wilful misconduct of the Agents or any of their
directors, officers, employees or agents.  Each Lender agrees that any
reasonable allocation of expenses or other amounts referred to in this paragraph
between this Agreement and the Facility B Credit Agreement shall be conclusive
and binding for all purposes.

          Each Lender acknowledges that it has, independently and without
reliance upon the Agents or any other Lender and based on such documents and
information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement.  Each Lender also acknowledges that it
will, independently and without reliance upon the Agents or any other Lender and
based on such documents and information as it shall from time to time deem
appropriate, continue to make its own decisions in taking or not taking action
under or based upon this Agreement or any other Loan Document, any related
agreement or any document furnished hereunder or thereunder.

Borrower, the Agents and the Lenders may treat each person whose name is
recorded in the Register pursuant to the terms hereof as a Lender hereunder for

not ordinarily be provided in connection with assignments or participations of
Competitive Loans.

          (h)  Any Lender may at any time assign all or any portion of its
rights under this Agreement to a Federal Reserve Bank; provided that no such
                                                       --------             
assignment shall release a Lender from any of its obligations hereunder.  In
order to facilitate such an assignment to a Federal Reserve Bank, the Borrower
shall, to the extent permissible without registration under applicable
regulations of the ICC, at the request of the assigning Lender, duly execute and
deliver to the assigning Lender a promissory note or notes evidencing the Loans
made to the Borrower by the assigning Lender hereunder.

          (i)  The Borrower shall not assign or delegate any of its rights or
duties hereunder without the prior written consent of the Lenders.

          SECTION 9.05.  Expenses; Indemnity.  (a)  The Borrower agrees to pay
                         --------------------                                 
all out-of-pocket expenses incurred by the Agents in connection with the
preparation of this Agreement and the other Loan Documents or in connection with
any amendments, modifications or waivers of the provisions hereof or thereof
(whether or not the transactions hereby contemplated shall be consummated) or
incurred by the Agents or any Lender in connection with the enforcement or

                                                                              69

protection of their rights in connection with this Agreement and the other Loan
Documents or in connection with the Loans made hereunder, including the
reasonable fees, charges and disbursements of Cravath, Swaine & Moore, counsel
for the Agents, and, in connection with any such amendment, modification or
waiver or any such enforcement or protection, the reasonable fees, charges and
disbursements of any other counsel for the Agents or any Lender.  The Borrower
further agrees that it shall indemnify the Lenders from and hold them harmless
against any documentary taxes, assessments or charges made by any Governmental
Authority by reason of the execution and delivery of this Agreement or any of
the other Loan Documents.

          (b)  The Borrower agrees to indemnify the Agents, each Lender and each
of their respective directors, officers, employees and agents (each such person
being called an "Indemnitee") against, and to hold each Indemnitee harmless
from, any and all losses, claims, damages, liabilities and related expenses,
including reasonable counsel fees, charges and disbursements, incurred by or
asserted against any Indemnitee arising out of, in any way connected with, or as
a result of (i) the execution or delivery of this Agreement or any other Loan
Document or any agreement or instrument contemplated thereby, the performance by
the parties thereto of their respective obligations thereunder or the
consummation of the transactions contemplated thereby, (ii) the use of the
proceeds of the Loans or (iii) any claim, litigation, investigation or
proceeding relating to any of the foregoing to which such Indemnitee reasonably
believes that it may become a party, whether or not any Indemnitee is a party
thereto; provided that such indemnity shall not, as to any Indemnitee, be
         --------                                                        
available to the extent that such losses, claims, damages, liabilities or
related expenses are determined by a court of competent jurisdiction by final
and nonappealable judgment to have resulted from the gross negligence or wilful
misconduct of such Indemnitee.

          (c)  The provisions of this Section 9.05 shall remain operative and in
full force and effect regardless of the expiration of the term of this
Agreement, the consummation of the transactions contemplated hereby, the
repayment of any of the Loans, the invalidity or unenforceability of any term or
provision of this Agreement or any other Loan Document, or any investigation
made by or on behalf of the Agents or any Lender.  All amounts due under this
Section 9.05 shall be payable on written demand therefor.

          SECTION 9.06.  Right of Setoff.  If an Event of Default shall have

occurred and be continuing, each Lender is hereby authorized at any time and
from time to time, to the fullest extent permitted by law, to set off and apply
any and all deposits (general or special, time or demand, provisional or final)
at any time held and other indebtedness at any time owing by such Lender to or
for the credit or the account of the Borrower against any of and all the
obligations of the Borrower now or hereafter existing under this Agreement and
other Loan Documents held by such Lender, irrespective of whether or not such
Lender shall have made any demand under this Agreement or such other Loan
Document and although such obligations may be unmatured.  Each Lender agrees
promptly to notify the Borrower after any such setoff and application made by
such Lender, provided that the failure to give such notice shall not affect the
             --------                                                          
validity of such setoff and application.  The rights of each Lender under this
Section are in addition to other rights and remedies (including other rights of
setoff) which such Lender may have.

          SECTION 9.07.  Applicable Law.  THIS AGREEMENT AND THE OTHER LOAN
                         ---------------                                   
DOCUMENTS SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE
STATE OF NEW YORK.

          SECTION 9.08.  Waivers; Amendment.  (a)  No failure or delay of the
                         -------------------                                 
Agents or any Lender in exercising any power or right hereunder shall operate as
a waiver thereof, nor shall any single or partial exercise of any such right or
power, or any abandonment or discontinuance of steps to enforce such a right or
power, preclude any other or further exercise thereof or the exercise of any
other right or power.  The rights and remedies of the Agents and the Lenders
hereunder and under the other Loan Documents are cumulative and are not
exclusive of any rights or remedies which they would otherwise have.  No waiver
of any provision of this Agreement or any other Loan Document or consent to any
departure by the Borrower therefrom shall in any event be effective unless the
same shall be permitted by paragraph (b) below, and then such waiver or consent
shall be effective only in the specific instance and for the purpose for which
given.  No notice or demand on the Borrower in any case shall entitle the
Borrower to any other or further notice or demand in similar or other
circumstances.

          (b)  Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to an agreement or agreements in writing
entered into by the

Borrower and the Required Lenders; provided, however, that no such agreement
                                   --------  -------                        
shall (i) decrease the principal amount of, or extend the maturity of or any
scheduled principal payment date or date for the payment of any interest on, any
Loan, or waive or excuse any such payment or any part thereof, or decrease the
rate of interest on any Loan, without the prior written consent of each Lender
affected thereby, (ii) change or extend the Commitment or decrease the Facility
Fees of any Lender without the prior written consent of such Lender, or (iii)
amend or modify the provisions of Section 2.17, the provisions of this Section,
any provision of this agreement which by its terms requires the consent or
approval of all Lenders or the definition of "Required Lenders", without the
prior written consent of each Lender; provided further that no such agreement
                                      ----------------                       
shall amend, modify or otherwise affect the rights or duties of the Agents
hereunder without the prior written consent of the Agents.

          SECTION 9.09.  Interest Rate Limitation.  Notwithstanding anything
                         -------------------------                          
herein to the contrary, if at any time the applicable interest rate, together
with all fees and charges which are treated as interest under applicable law
(collectively the "Charges"), as provided for herein or in any other document
executed in connection herewith, or otherwise contracted for, charged, received,
taken or reserved by any Lender, shall exceed the maximum lawful rate (the
"Maximum Rate") which may be contracted for, charged, taken, received or
reserved by such Lender in accordance with applicable law, the rate of interest
payable on the Loans of such Lender, together with all Charges payable to such
Lender, shall be limited to the Maximum Rate.

          SECTION 9.10.  Entire Agreement.  This Agreement and the other Loan
                         -----------------                                   
Documents constitute the entire contract between the parties relative to the
subject matter hereof.  Any previous agreement among the parties with respect to
the subject matter hereof is superseded by this Agreement and the other Loan
Documents.  Nothing in this Agreement or in the other Loan Documents, expressed
or implied, is intended to confer upon any party other than the parties hereto
and thereto any rights, remedies, obligations or liabilities under or by reason
of this Agreement or the other Loan Documents.

          SECTION 9.11.  Severability.  In the event any one or more of the
                         -------------                                     
provisions contained in this Agreement or in any other Loan Document should be

unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained herein and therein shall not in any way be
affected or impaired thereby.  The parties shall endeavor in good-faith
negotiations to replace the invalid, illegal or unenforceable provisions with
valid provisions the economic effect of which comes as close as possible to that
of the invalid, illegal or unenforceable provisions.

          SECTION 9.12.  Counterparts.  This Agreement may be executed in two or
                         -------------                                          
more counterparts, each of which shall constitute an original but all of which
when taken together shall constitute but one contract, and shall become
effective as provided in Section 9.03.

          SECTION 9.13.  Headings.  Article and Section headings and the Table
                         ---------                                            
of Contents used herein are for convenience of reference only, are not part of
this Agreement and are not to affect the construction of, or to be taken into
consideration in interpreting, this Agreement.

          SECTION 9.14.  Jurisdiction; Consent to Service of Process.  (a)  The
                         ----------------------------------- --------          
Borrower hereby irrevocably and unconditionally submits, for itself and its
property, to the nonexclusive jurisdiction of any New York State court or
Federal court of the United States of America sitting in New York City, and any
appellate court from any thereof, in any action or proceeding arising out of or
relating to this Agreement or the other Loan Documents, or for recognition or
enforcement of any judgment, and each of the parties hereto hereby irrevocably
and unconditionally agrees that all claims in respect of any such action or
proceeding may be heard and determined in such New York State or, to the extent
permitted by law, in such Federal court.  Each of the parties hereto agrees that
a final judgment in any such action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any other manner
provided by law.  Nothing in this Agreement shall affect any right that any
Lender may otherwise have to bring any action or proceeding relating to this
Agreement or the other Loan Documents against the Borrower or its properties in
the courts of any jurisdiction.

          (b)  The Borrower hereby irrevocably and unconditionally waives, to
the fullest extent it may legally and effectively do so, any objection which it
may now or hereafter have to the laying of venue of any suit, action or
proceeding arising out of or relating to this agreement or

the other Loan Documents in any New York State or Federal court sitting in New
York City.  Each of the parties hereto hereby irrevocably waives, to the fullest
extent permitted by law, the defense of an inconvenient forum to the maintenance
of such action or proceeding in any such court.

          (c)  Each party to this Agreement irrevocably consents to service of
process in the manner provided for notices in Section 9.01.  Nothing in this
Agreement will

affect the right of any party to this Agreement to serve process in any other
manner permitted by law.


          IN WITNESS WHEREOF, the Borrower, the Lenders, the Administrative
Agent and the CAF Agent have caused this Agreement to be duly executed by their
respective authorized officers as of the day and year first above written.

The proceeds of such borrowings are to be used for general corporate purposes,
including providing backup liquidity for the Borrower's commercial paper program
and for acquisitions of any person approved by the board of directors or other
comparable body of such person.  The Lenders are willing to extend such credit
to the Borrower on the terms and subject to the conditions herein set forth.

          Accordingly, the Borrower, the Lenders, the Administrative Agent and
the CAF Agent agree as follows:

ARTICLE II.  THE CREDITS

          SECTION 2.01.  Commitments.  Subject to the terms and conditions and
                         -----------
relying upon the representations and warranties herein set forth, each Lender
agrees, severally and not jointly, to make Standby Loans to the Borrower, at any
time and from time to time on and after the date hereof and until the earlier of
the Maturity Date and the termination of the Commitment of such Lender, in an
aggregate principal amount at any time outstanding not to exceed such Lender's
Commitment minus the amount by which the Competitive Loans outstanding at such
time shall be deemed to have used such Commitment pursuant to Section 2.17,
subject, however, to the conditions that (a) at no time shall (i) the sum of (x)
the outstanding aggregate principal amount of all Standby Loans made by all
Lenders plus (y) the outstanding aggregate principal amount of all Competitive
Loans made by all Lenders exceed (ii) the Total Commitment and (b) at all times
the outstanding aggregate principal amount of all Standby Loans made by each
Lender shall equal the product of (i) the percentage which its Commitment
represents of the Total Commitment times (ii) the outstanding aggregate
principal amount of all Standby Loans made pursuant to Section 2.04. Each
Lender's Commitment is set forth opposite its respective name in Schedule 2.01.
Such Commitments may be terminated or reduced from time to time pursuant to
Section 2.12. Within the foregoing limits, the Borrower may borrow, pay or
prepay and reborrow hereunder, on and after the Closing Date and prior to the
Maturity Date, subject to the terms, conditions and limitations set forth
herein.

          SECTION 2.02.  Loans.  (a)  Each Standby Loan shall be made as part 
                         -----
of a Borrowing consisting of Loans made by the Lenders ratably in accordance
with their Commitments; provided, however, that the failure of any Lender to
                        --------  -------
make any Standby Loan shall not in itself relieve any other Lender of its
obligation to lend hereunder (it being understood, however, that no Lender shall
be responsible for the failure of any other Lender to make any Loan required to
be made by such other Lender). Each Competitive Loan shall be made in accordance
with the procedures set forth in Section 2.03. The Loans comprising any
Borrowing shall be (i) in the case of Competitive Loans, in an aggregate
principal amount which is an integral multiple of $1,000,000 and not less than
$5,000,000 and (ii) in the case of Standby Loans, in an aggregate principal
amount which is an integral multiple of $1,000,000 and not

                                                                              20

less than $20,000,000 (or an aggregate principal amount equal to the remaining
balance of the available Commitments).

          (b)  Each Competitive Borrowing shall be comprised entirely of 
Eurodollar Competitive Loans or Fixed Rate Loans and each Standby Borrowing
shall be comprised entirely of Eurodollar Standby Loans, CD Loans or ABR Loans,
as the Borrower may request pursuant to Section 2.03 or 2.04, as applicable.
Each Lender may at its option make any Eurodollar Loan by causing any domestic
or foreign branch or Affiliate of such Lender to make such Loan; provided that
                                                                 --------
any exercise of such option shall not affect the obligation of the Borrower to
repay such Loan in accordance with the terms of this Agreement. Borrowings of
more than one Type may be outstanding at the same time; provided, however, that
                                                        --------  -------
the Borrower shall not be entitled to request any Borrowing which, if made,
would result in an aggregate of more than twelve separate Standby Loans of any
Lender being outstanding hereunder at any one time. For purposes of the
foregoing, Loans having different Interest Periods, regardless of whether they
commence or end on the same date, shall be considered separate Loans.

          (c)  Subject to Section 2.05, each Lender shall make each Loan to be 
made by it hereunder on the proposed date thereof by wire transfer of
immediately available funds to the Administrative Agent in Houston, Texas, not
later than 1:00 p.m., New York City time, and the Administrative Agent shall by
3:00 p.m., New York City time, credit the amounts so received in immediately
available funds to an account designated by the Borrower with the Administrative
Agent or, if a Borrowing shall not occur on such date because any condition
precedent herein specified shall not have been met, return the amounts so
received to the respective Lenders. Competitive Loans shall be made by the
Lender or Lenders whose Competitive Bids therefor are accepted pursuant to
Section 2.03 in the amounts so accepted and Standby Loans shall be made by the
Lenders pro rata in accordance with Section 2.17. Unless the Administrative
Agent shall have received notice from a Lender prior to the date of any
Borrowing (or prior to 12:00 noon on the date of such borrowing, in the case of
an ABR Borrowing) that such Lender will not make available to the Administrative
Agent such Lender's portion of such Borrowing, the Administrative Agent may
assume that such Lender has made such portion available to the Administrative
Agent on the date of such Borrowing in accordance with this paragraph (c) and
the

                                                                              21

Administrative Agent may, in reliance upon such assumption, make available to
the Borrower on such date a corresponding amount.  If and to the extent that
such Lender shall not have made such portion available to the Administrative
Agent, such Lender and the Borrower severally agree to repay to the
Administrative Agent forthwith on demand such corresponding amount together with
interest thereon, for each day from the date such amount is made available to
the Borrower until the date such amount is repaid to the Administrative Agent at
(i) in the case of the Borrower, the interest rate applicable at the time to the
Loans comprising such Borrowing and (ii) in the case of such Lender, the Federal
Funds Effective Rate.  If such Lender shall repay to the Administrative Agent
such corresponding amount, such amount shall constitute such Lender's Loan as
part of such Borrowing for purposes of this Agreement.

          (d)  Notwithstanding any other provision of this Agreement, the 
Borrower shall not be entitled to request any Borrowing if the Interest Period
requested with respect thereto would end after the Maturity Date.

          SECTION 2.03.  Competitive Bid Procedure.  (a)  In order to request
                         --------------------------                          
Competitive Bids, the Borrower shall hand deliver or telecopy (or communicate by
telephone with prompt confirmation by telecopy or in writing) to the CAF Agent
(with a copy to the Administrative Agent) a duly completed Competitive Bid
Request in the form of Exhibit A-1 hereto, to be received by the CAF Agent (and
the Administrative Agent) (i) in the case of a Eurodollar Competitive Borrowing,
not later than 10:30 a.m., New York City time, four Business Days before a
proposed Competitive Borrowing and (ii) in the case of a Fixed Rate Borrowing,
not later than 10:30 a.m., New York City time, one Business Day before a
proposed Competitive Borrowing.  No CD Loan or ABR Loan shall be requested in,
or made pursuant to, a Competitive Bid Request.  A Competitive Bid Request that
does not conform substantially to the format of Exhibit A-1 may be rejected in
the CAF Agent's sole discretion, and the CAF Agent shall promptly notify the
Borrower of such rejection by telecopier (or by telephone with prompt
confirmation by telecopier or in writing).  Such request shall in each case
refer to this Agreement and specify (x) whether the Borrowing then being
requested is to be a Eurodollar Borrowing or a Fixed Rate Borrowing, (y) the
date of such Borrowing (which shall be a Business Day) and the aggregate
principal amount thereof which shall be in a minimum principal amount of
$5,000,000 and in an integral multiple

of $1,000,000, and (z) the Interest Period with respect thereto (which may not
end after the Maturity Date).  Promptly after its receipt of a Competitive Bid
Request that is not rejected as aforesaid, the CAF Agent shall invite by
telecopier (in the form set forth in Exhibit A-2 hereto) the Lenders to bid, on
the terms and conditions of this Agreement, to make Competitive Loans pursuant
to the Competitive Bid Request.

          (b)  Each Lender may, in its sole discretion, make one or more 
Competitive Bids to the Borrower responsive to a Competitive Bid Request. Each
Competitive Bid by a Lender must be received by the CAF Agent via telecopier, in
the form of Exhibit A-3 hereto, (i) in the case of a Eurodollar Competitive
Borrowing, not later than 9:30 a.m., New York City time, three Business Days
before a proposed Competitive Borrowing and (ii) in the case of a Fixed Rate
Borrowing, not later than 9:30 a.m., New York City time, on the day of a
proposed Competitive Borrowing. Multiple bids will be accepted by the CAF Agent.
Competitive Bids that do not conform substantially to the format of Exhibit A-3
may be rejected by the CAF Agent, and the CAF Agent shall notify the Lender
making such nonconforming bid of such rejection as soon as practicable. Each
Competitive Bid shall refer to this Agreement and specify (x) the principal
amount (which shall be in a minimum principal amount of $5,000,000 and in an
integral multiple of $1,000,000 and which may equal the entire principal amount
of the Competitive Borrowing requested by the Borrower) of the Competitive Loan
or Loans that the Lender is willing to make to the Borrower, (y) the Competitive
Bid Rate or Rates at which the Lender is prepared to make the Competitive Loan
or Loans and (z) the Interest Period and the last day thereof. If any Lender
shall elect not to make a Competitive Bid, such Lender shall so notify the CAF
Agent by telecopier (I) in the case of Eurodollar Competitive Loans, not later
than 9:30 a.m., New York City time, three Business Days before a proposed
Competitive Borrowing, and (II) in the case of Fixed Rate Loans, not later than
9:30 a.m., New York City time, on the day of a proposed Competitive Borrowing;
provided, however, that failure by any Lender to give such notice shall not
- --------  -------
cause such Lender to be obligated to make any Competitive Loan as part of such
Competitive Borrowing. A Competitive Bid submitted by a Lender pursuant to this
paragraph (b) shall be irrevocable.

          (c)  The CAF Agent shall promptly notify the Borrower by telecopier 
(or by telephone promptly confirmed

by telecopier) of all the Competitive Bids made, the Competitive Bid Rate and
the principal amount of each Competitive Loan in respect of which a Competitive
Bid was made and the identity of the Lender that made each bid.  The CAF Agent
shall send a copy of all Competitive Bids to the Borrower for its records as
soon as practicable after completion of the bidding process set forth in this
Section 2.03.

          (d)  The Borrower may in its sole and absolute discretion, subject 
only to the provisions of this paragraph (d), accept or reject any Competitive
Bid referred to in paragraph (c) above. The Borrower shall notify the CAF Agent
by telephone, confirmed by telecopier in the form of a Competitive Bid
Accept/Reject Letter, whether and to what extent it has decided to accept or
reject any of or all the bids referred to in paragraph (c) above, (x) in the
case of a Eurodollar Competitive Borrowing, not later than 10:30 a.m., New York
City time, three Business Days before a proposed Competitive Borrowing, and (y)
in the case of a Fixed Rate Borrowing, not later than 10:30 a.m., New York City
time, on the day of a proposed Competitive Borrowing; provided, however, that
                                                      --------  -------
(i) the failure by the Borrower to give such notice shall be deemed to be a
rejection of all the bids referred to in paragraph (c) above, (ii) the Borrower
shall not accept a bid made at a particular Competitive Bid Rate if the Borrower
has decided to reject a bid made at a lower Competitive Bid Rate, (iii) the
aggregate amount of the Competitive Bids accepted by the Borrower shall not
exceed the principal amount specified in the Competitive Bid Request, (iv) if
the Borrower shall accept a bid or bids made at a particular Competitive Bid
Rate but the amount of such bid or bids shall cause the total amount of bids to
be accepted by the Borrower to exceed the amount specified in the Competitive
Bid Request, then the Borrower shall accept a portion of such bid or bids in an
amount equal to the amount specified in the Competitive Bid Request less the
amount of all other Competitive Bids accepted with respect to such Competitive
Bid Request, which acceptance, in the case of multiple bids at such Competitive
Bid Rate, shall be made pro rata in accordance with the amount of each such bid
at such Competitive Bid Rate, and (v) except pursuant to clause (iv) above, no
bid shall be accepted for a Competitive Loan unless such Competitive Loan is in
a minimum principal amount of $5,000,000 and an integral multiple of $1,000,000;
provided further, however, that if a Competitive Loan must be in an amount less
- -------- -------  ------
than $5,000,000 because of the

provisions of clause (iv) above, such Competitive Loan may be for a minimum of
$1,000,000 or any integral multiple thereof, and in calculating the pro rata
allocation of acceptances of portions of multiple bids at a particular
Competitive Bid Rate pursuant to clause (iv) above the amounts shall be rounded
to integral multiples of $1,000,000 in a manner which shall be in the discretion
of the Borrower.  A notice given by the Borrower pursuant to this paragraph (d)
shall be irrevocable.

          (e)  The CAF Agent shall promptly notify each bidding Lender whether 
or not its Competitive Bid has been accepted (and if so, in what amount and at
what Competitive Bid Rate) by telecopy sent by the CAF Agent, and each
successful bidder will thereupon become bound, subject to the other applicable
conditions hereof, to make the Competitive Loan in respect of which its bid has
been accepted. The CAF Agent shall also promptly notify the Administrative Agent
of the Competitive Bids that have been accepted, the amounts thereof and the
Competitive Bid Rates applicable thereto.

          (f)  If the CAF Agent shall become a Lender and shall elect to submit
a Competitive Bid in its capacity as a Lender, it shall submit such bid directly
to the Borrower one quarter of an hour earlier than the earliest time at which
the other Lenders are required to submit their bids to the CAF Agent pursuant to
paragraph (b) above.  The CAF Agent will in no event disclose the terms of any
Lender's Competitive Bid to any other Lender; provided that following the
                                              --------                   
acceptance or rejection of Competitive Bids submitted in response to any
Competitive Bid Request, the CAF Agent may at the request of any Lender disclose
information as to the range of the Competitive Bid Rates at which Competitive
Bids were submitted or accepted.

          (g)  All notices required by this Section 2.03 shall be given in 
accordance with Section 9.01.

          SECTION 2.04.  Standby Borrowing Procedure.  In order to request a 
                         ---------------------------
Standby Borrowing, the Borrower shall hand deliver or telecopy (or communicate
by telephone with prompt confirmation by telecopy or in writing) to the
Administrative Agent a duly completed Standby Borrowing Request in the form of
Exhibit A-5 (a) in the case of a Eurodollar Standby Borrowing, not later than
11:00 a.m., New York City time, three Business Days before a proposed borrowing,
(b) in the case of a CD Borrowing, not later than

11:00 a.m., New York City time, two Business Days before a proposed borrowing
and (c) in the case of an ABR Borrowing, not later than 11:00 a.m., New York
City time, on the day of a proposed borrowing.  No Fixed Rate Loan shall be
requested or made pursuant to a Standby Borrowing Request.  Such notice shall be
irrevocable and shall in each case specify (i) whether the Borrowing then being
requested is to be a Eurodollar Borrowing, a CD Borrowing or an ABR Borrowing;
(ii) the date of such Borrowing (which shall be a Business Day) and the amount
thereof which shall be in a minimum principal amount of $20,000,000 and in an
integral multiple of $1,000,000; and (iii) if such Borrowing is to be a
Eurodollar Borrowing or CD Borrowing, the Interest Period with respect thereto.
If no election as to the Type of Borrowing is specified in any such notice, then
the requested Borrowing shall be an ABR Borrowing.  If no Interest Period with
respect to any Eurodollar Borrowing or CD Borrowing is specified in any such
notice, then the Borrower shall be deemed to have selected an Interest Period of
one month's duration, in the case of a Eurodollar Borrowing, or 30 days'
duration, in the case of a CD Borrowing.  If the Borrower shall not have given
notice in accordance with this Section 2.04 of its election to refinance a
Standby Borrowing prior to the end of the Interest Period in effect for such
Borrowing, then the Borrower shall (unless such Borrowing is repaid at the end
of such Interest Period) be deemed to have given notice of an election to
refinance such Borrowing with an ABR Borrowing.  The Administrative Agent shall
promptly advise the Lenders of any notice given pursuant to this Section 2.04
and of each Lender's portion of the requested Borrowing.

          SECTION 2.05.  Refinancings.  The Borrower may refinance all or any 
                         ------------
part of any Competitive Borrowing or Standby Borrowing with a Borrowing of the
same or a different Type made pursuant to Section 2.03 or Section 2.04, subject
to the conditions and limitations set forth herein and elsewhere in this
Agreement, including refinancings of Competitive Borrowings with Standby
Borrowings and Standby Borrowings with Competitive Borrowings. Any Borrowing or
part thereof so refinanced shall be deemed to be repaid in accordance with
Section 2.08 with the proceeds of a new Borrowing hereunder and the proceeds of
the new Borrowing, to the extent they do not exceed the principal amount of the
Borrowing being refinanced, shall not be paid by the Lenders to the
Administrative Agent or by the Administrative Agent to the

Borrower pursuant to Section 2.02(c); provided, however, that (i) if the
                                      --------  -------                 
principal amount extended by a Lender in a refinancing is greater than the
principal amount extended by such Lender in the Borrowing being refinanced, then
such Lender shall pay such difference to the Administrative Agent for
distribution to the Lenders described in (ii) below, (ii) if the principal
amount extended by a Lender in the Borrowing being refinanced is greater than
the principal amount being extended by such Lender in the refinancing, the
Administrative Agent shall return the difference to such Lender out of amounts
received pursuant to (i) above, and (iii) to the extent any Lender fails to pay
the Administrative Agent amounts due from it pursuant to (i) above, any Loan or
portion thereof being refinanced with such amounts shall not be deemed repaid in
accordance with Section 2.08 and shall be payable by the Borrower.

          SECTION 2.06.  Conversion and Continuation of Standby Borrowings.  The
                         --------------------------------------------------     
Borrower shall have the right at any time upon prior irrevocable notice to the
Administrative Agent (i) not later than 11:00 a.m., New York City time, one
Business Day prior to conversion, to convert any Eurodollar Standby Borrowing or
CD Borrowing into an ABR Borrowing, (ii) not later than 11:00 a.m., New York
City time, two Business Days prior to conversion or continuation, to convert any
Eurodollar Standby Borrowing or ABR Borrowing into a CD Borrowing or to continue
any CD Borrowing as a CD Borrowing for an additional Interest Period, (iii) not
later than 11:00 a.m., New York City time, three Business Days prior to
conversion or continuation, to convert any ABR Borrowing or CD Borrowing into a
Eurodollar Standby Borrowing or to continue any Eurodollar Standby Borrowing as
a Eurodollar Standby Borrowing for an additional Interest Period, (iv) not later
than 11:00 a.m., New York City time, three Business Days prior to conversion, to
convert the Interest Period with respect to any Eurodollar Standby Borrowing to
another permissible Interest Period and (v) not later than 11:00 a.m., New York
City time, two Business Days prior to conversion, to convert the Interest Period
with respect to any CD Borrowing to another permissible Interest Period, subject
in each case to the following:

          (a) each conversion or continuation shall be made pro rata among the
     Lenders in accordance with the respective principal amounts of the Loans
     comprising the converted or continued Standby Borrowing;

          (b) if less than all the outstanding principal amount of any Standby
     Borrowing shall be converted or continued, the aggregate principal amount
     of such Standby Borrowing converted or continued shall be an integral
     multiple of $1,000,000 and not less than $20,000,000;

          (c) if any Eurodollar Standby Borrowing or CD Borrowing is converted
     at a time other than the end of the Interest Period applicable thereto, the
     Borrower shall pay, upon demand, any amounts due to the Lenders pursuant to
     Section 2.16;

          (d) any portion of a Standby Borrowing maturing or required to be
     repaid in less than one month may not be converted into or continued as a
     Eurodollar Standby Borrowing;

          (e) any portion of a Standby Borrowing maturing or required to be
     repaid in less than 30 days may not be converted into or continued as a CD
     Borrowing;

          (f) any portion of a Eurodollar Standby Borrowing or CD Borrowing
     which cannot be converted into or continued as a Eurodollar Standby
     Borrowing or a CD Borrowing by reason of clauses (d) and (e) above shall be
     automatically converted at the end of the Interest Period in effect for
     such Borrowing into an ABR Borrowing; and

          (g) no Interest Period may be selected for any Eurodollar Standby
     Borrowing or CD Borrowing that would end later than the Maturity Date.

          Each notice pursuant to this Section 2.06 shall be by hand delivery
or telecopier (or by telephone with  prompt confirmation by telecopier or in
writing) and irrevocable and shall refer to this Agreement and specify (i) the
identity and amount of the Standby Borrowing that the Borrower requests be
converted or continued, (ii) whether such Standby Borrowing is to be converted
to or continued as a Eurodollar Standby Borrowing, a CD Borrowing or an ABR
Borrowing, (iii) if such notice requests a conversion, the date of such
conversion (which shall be a Business Day) and (iv) if such Standby Borrowing is
to be converted to or continued as a Eurodollar Standby Borrowing or CD
Borrowing, the Interest Period with respect thereto.   If no Interest Period is
specified in any such notice with

                                                                              28

respect to any conversion to or continuation as a Eurodollar Standby Borrowing
or CD Borrowing, the Borrower shall be deemed to have selected an Interest
Period of one month's duration, in the case of a Eurodollar Standby Borrowing,
or 30 days' duration, in the case of a CD Borrowing.  The Administrative Agent
shall advise the other Lenders of any notice given pursuant to this Section 2.06
and of each Lender's portion of any converted or continued Standby Borrowing.
If the Borrower shall not have given notice in accordance with this Section 2.06
to continue any Standby Borrowing into a subsequent Interest Period (and shall
not otherwise have given notice in accordance with this Section 2.06 to convert
such Standby Borrowing), such Standby Borrowing shall, at the end of the
Interest Period applicable thereto (unless repaid pursuant to the terms hereof),
automatically be continued into a new Interest Period as an ABR Borrowing.

through the Administrative Agent, on each March 31, June 30, September 30 and
December 31 and on the Maturity Date, a facility fee (a "Facility Fee") equal to
the Applicable Fee Percentage on the daily average amount of the Commitment of
such Lender, whether used or unused (and whether or not the conditions set forth
in Section 4.01 shall have been satisfied), during the preceding quarter (or
shorter period commencing with the date hereof, or ending with the Maturity Date
or any date on which the Commitment of such Lender shall be terminated and all
outstanding Loans of such Lender repaid).  All Facility Fees shall be computed
on the basis of the actual number of days elapsed in a year of 365 or 366 days,
as appropriate.  The Facility Fee due to each Lender shall commence to accrue on
the date of this Agreement, and shall cease to accrue on the earlier of the
Maturity Date and the date on which the Commitment of such Lender shall have
been terminated and all outstanding Loans of such Lender repaid.

          (b)  The Borrower agrees to pay the Agents, through the Administrative
Agent, for the Agents' own accounts, the fees set forth in the Engagement Letter
and in the Fee Letter dated April 7, 1994 among the Administrative Agent,
Chemical Securities Inc. and the Borrower (the "Agent Fees") at the times and in
the amounts set forth therein.

          (c)  All Fees shall be paid on the dates due, in immediately available
funds, to the Administrative Agent for distribution, if and as appropriate,
among the Lenders.

Once paid, none of the Fees (other than fees paid in error and not required to
have been paid under the terms of this Agreement) shall be refundable under any
circumstances.

          SECTION 2.08.  Repayment of Loans.  (a)  The Borrower agrees to pay
                         -------------------                                 
the outstanding principal balance of each Loan on the last day of the Interest
Period applicable to such Loan and on the Maturity Date.  Each Loan shall bear
interest from the date of the Borrowing of which such Loan is a part on the
outstanding principal balance thereof as set forth in Section 2.09.

          (b)  Each Lender shall, and is hereby authorized by the Borrower to,
maintain, in accordance with its usual practice, records evidencing the
indebtedness of the Borrower to such Lender hereunder from time to time,
including the amounts and Types of and the Interest Periods applicable to the
Loans made by such Lender from time to time and the amounts of principal and
interest paid to such Lender from time to time in respect of such Loans.

          (c)  The entries made in the records maintained pursuant to paragraph
(b) of this Section 2.08 and in the Register maintained by the Administrative
Agent pursuant to Section 9.04(d) shall be prima facie evidence of the existence
and amounts of the obligations of the Borrower to which such entries relate;
                                                                            
provided, however, that the failure of any Lender or the Administrative Agent to

maintain or to make any entry in such records or the Register, as applicable, or
any error therein shall not in any manner affect the obligation of the Borrower
to repay the Loans in accordance with the terms of this Agreement.

          SECTION 2.09.  Interest on Loans.  (a)  Subject to the provisions of
                         ------------------                                   
Section 2.10, the Loans comprising each Eurodollar Borrowing shall bear interest
(computed on the basis of the actual number of days elapsed over a year of 360
days) at a rate per annum equal to (i) in the case of each Eurodollar Standby
Loan, the LIBO Rate for the Interest Period in effect for such Borrowing plus
the Applicable Margin from time to time in effect and (ii) in the case of each
Eurodollar Competitive Loan, the LIBO Rate for the Interest Period in effect for
such Borrowing plus the Margin offered by the Lender making such Loan and
accepted by the Borrower pursuant to Section 2.03.

          (b)  Subject to the provisions of Section 2.10, the Loans comprising
each CD Borrowing shall bear interest

(computed on the basis of the actual number of days elapsed over a year of 360
days) at a rate per annum equal to the Adjusted CD Rate for the Interest Period
in effect for such Borrowing plus the Applicable Margin from time to time in
effect.

          (c)  Subject to the provisions of Section 2.10, the Loans comprising
each ABR Borrowing shall bear interest (computed on the basis of the actual
number of days elapsed over a year of 365 or 366 days, as appropriate, when
determined by reference to the Prime Rate and over a year of 360 days at all
other times) at a rate per annum equal to the Alternate Base Rate.

          (d)  Subject to the provisions of Section 2.10, each Fixed Rate Loan
shall bear interest at a rate per annum (computed on the basis of the actual
number of days elapsed over a year of 360 days) equal to the fixed rate of
interest offered by the Lender making such Loan and accepted by the Borrower
pursuant to Section 2.03.

          (e)  Interest on each Loan shall be payable in arrears on each
Interest Payment Date applicable to such Loan except as otherwise provided in
this Agreement.  The applicable LIBO Rate, Adjusted CD Rate or Alternate Base
Rate for each Interest Period or day within an Interest Period, as the case may
be, shall be determined by the Administrative Agent, and such determination
shall be conclusive absent manifest error.  The Administrative Agent shall
promptly advise the Borrower and each Lender, as appropriate, of such
determination.

          SECTION 2.10.  Default Interest.  If the Borrower shall default in the
                         -----------------                                      
payment of the principal of or interest on any Loan or any other amount becoming
due hereunder, whether by scheduled maturity, notice of prepayment, acceleration
or otherwise, the Borrower shall on demand from time to time from the
Administrative Agent pay interest, to the extent permitted by law, on such
defaulted amount up to (but not including) the date of actual payment (after as
well as before judgment) at a rate per annum (computed on the basis of the
actual number of days elapsed over a year of 365 or 366 days, as appropriate,
when determined by reference to the Prime Rate and over a year of 360 days at
all other times) equal to the Alternate Base Rate plus 1%.

          SECTION 2.11.  Alternate Rate of Interest.  (a)  In the event, and on
                         ---------------------------

Business Days prior to the commencement of any Interest Period for a Eurodollar
Borrowing the Administrative Agent shall have determined (i) that dollar
deposits in the principal amounts of the Eurodollar Loans comprising such
Borrowing are not generally available in the London interbank market, or (ii)
that the rates at which such dollar deposits are being offered will not
adequately and fairly reflect the cost to any Lender of making or maintaining
its Eurodollar Loan during such Interest Period, or (iii) that reasonable means
do not exist for ascertaining the LIBO Rate, the Administrative Agent shall, as
soon as practicable thereafter, give written or telecopy notice of such
determination to the Borrower and the Lenders.  In the event of any such
determination, until the Administrative Agent shall have advised the Borrower
and the Lenders that the circumstances giving rise to such notice no longer
exist, (A) in the event the circumstances referred to in (i) or (iii) above are
applicable, any request by the Borrower for a Eurodollar Competitive Borrowing
pursuant to Section 2.03 shall be of no force and effect and shall be denied by
the CAF Agent and (B) any request by the Borrower for a Eurodollar Standby
Borrowing shall be deemed to be a request for an ABR Borrowing (x) as to all
Lenders, in the event the circumstances referred to in (i) or (iii) above are
applicable, or (y) as to each affected Lender, in the event only the
circumstances referred to in (ii) above are applicable.  In the event the
circumstances referred to in (ii) above are applicable, all payments and
prepayments of principal which would otherwise have been made on account of
Eurodollar Loans of the affected Lender shall instead be applied to repay the
ABR Loans made by such Lender in lieu of such Eurodollar Loans.  Each
determination by the Administrative Agent hereunder shall be conclusive absent
demonstrable error.

          (b)  In the event, and on each occasion, that on or before the day on
which the Adjusted CD Rate for a CD Borrowing is to be determined the
Administrative Agent shall have determined (i) that such Adjusted CD Rate cannot
be determined for any reason, including the inability of the Administrative
Agent to obtain sufficient bids in accordance with the terms of the definition
of Fixed CD Rate, or (ii) that the Adjusted CD Rate for such CD Borrowing will
not adequately and fairly reflect the cost to any Lender of making or
maintaining its CD Loan during such Interest Period, the Administrative Agent
shall, as soon as practicable thereafter, give written or telecopy notice of
such determination to the Borrower and the Lenders.  In the

event of any such determination, until the Administrative Agent shall have
advised the Borrower and the Lenders that the circumstances giving rise to such
notice no longer exist, any request by the Borrower for a CD Borrowing shall be
deemed to be a request for an ABR Borrowing (i) as to all Lenders, in the event
the circumstances referred to in (i) above are applicable, or (ii) as to each
affected Lender, in the event only the circumstances referred to in (ii) above
are applicable.  In the event the circumstances referred to under (ii) above are
applicable, all payments and prepayments of principal which would otherwise have
been made on account of CD Loans of the affected Lender shall instead be applied
to repay the ABR Loans made by such Lender in lieu of such Loans.  Each
determination by the Administrative Agent hereunder shall be conclusive absent
demonstrable error.

          SECTION 2.12.  Termination and Reduction of Commitments.  (a)  The
                         -----------------------------------------          
Commitments shall be automatically terminated on the Maturity Date.

          (b)  Upon at least three Business Days' prior irrevocable written or
telecopy notice to the Administrative Agent, the Borrower may at any time in
whole permanently terminate, or from time to time in part permanently reduce,
the Total Commitment; provided, however, that (i) each partial reduction of the
                      --------  -------                                        
Total Commitment shall be in an integral multiple of $1,000,000 and in a minimum
principal amount of $10,000,000 and (ii) no such termination or reduction shall
be made which would reduce the Total Commitment to an amount less than the
aggregate outstanding principal amount of the Competitive Loans.

          (c)  Each reduction in the Total Commitment hereunder shall be made
ratably among the Lenders in accordance with their respective Commitments.  The
Borrower shall pay to the Administrative Agent for the account of the Lenders,
on the date of each termination or reduction, the Facility Fees on the amount of
the Commitments so terminated or reduced accrued to but not including the date
of such termination or reduction.

          SECTION 2.13.  Prepayment.  (a)  The Borrower shall have the right at
                         -----------                                           
any time and from time to time to prepay any Standby Borrowing, in whole or in
part, upon giving written or telecopy notice (or telephone notice promptly
confirmed by written or telecopy notice) to the Administrative Agent:  (i)

time, three Business Days prior to prepayment, in the case of Eurodollar Loans,
(ii) before 12:00 noon, New York City time, two Business Days prior to
prepayment, in the case of CD Loans, and (iii) before 12:00 noon, New York City
time, one Business Day prior to prepayment, in the case of ABR Loans; provided,

multiple of $1,000,000 and not less than $10,000,000.  The Borrower shall not
have the right to prepay any Competitive Borrowing.

          (b)  On the date of any termination or reduction of the Commitments
pursuant to Section 2.12, the Borrower shall pay or prepay so much of the
Standby Borrowings as shall be necessary in order that the aggregate principal
amount of the Competitive Loans and Standby Loans outstanding will not exceed
the Total Commitment after giving effect to such termination or reduction.

          (c)  Each notice of prepayment shall specify the prepayment date and
the principal amount of each Borrowing (or portion thereof) to be prepaid, shall
be irrevocable and shall commit the Borrower to prepay such Borrowing (or
portion thereof) by the amount stated therein on the date stated therein.  All
prepayments under this Section 2.13 shall be subject to Section 2.16 but
otherwise without premium or penalty.  All prepayments under this Section 2.13
shall be accompanied by accrued interest on the principal amount being prepaid
to the date of payment.

          SECTION 2.14.  Reserve Requirements; Change in Circumstances.  (a)
                         ----------------------------------------------      
Notwithstanding any other provision herein, if after the date of this Agreement
any change in applicable law or regulation or in the interpretation or
administration thereof by any Governmental Authority charged with the
interpretation or administration thereof (whether or not having the force of
law) shall change the basis of taxation of payments to any Lender of the
principal of or interest on any Eurodollar Loan, CD Loan or Fixed Rate Loan made
by such Lender or any Fees or other amounts payable hereunder (other than
changes in respect of taxes imposed on the overall net income of such Lender by
the jurisdiction in which such Lender has its principal office or by any
political subdivision or taxing authority therein), or shall impose, modify or
deem applicable any reserve, special deposit or similar requirement against
assets of, deposits with or for the account of or credit extended by such Lender
(except any such reserve requirement which is reflected in the Adjusted CD
Rate), or shall impose on such Lender or the

London interbank market any other condition affecting this Agreement or any
Eurodollar Loan, CD Loan or Fixed Rate Loan made by such Lender, and the result
of any of the foregoing shall be to increase the cost to such Lender of making
or maintaining any Eurodollar Loan, CD Loan or Fixed Rate Loan or to reduce the
amount of any sum received or receivable by such Lender hereunder (whether of
principal, interest or otherwise) by an amount deemed by such Lender to be
material, then the Borrower will pay to such Lender upon demand such additional
amount or amounts as will compensate such Lender for such additional costs
incurred or reduction suffered.  Notwithstanding the foregoing, no Lender shall
be entitled to request compensation under this paragraph with respect to any
Competitive Loan if it shall have been aware of the change giving rise to such
request at the time of submission of the Competitive Bid pursuant to which such
Competitive Loan shall have been made.

          (b)  If any Lender shall have determined that the applicability of any
law, rule, regulation or guideline adopted pursuant to or arising out of the
July 1988 report of the Basle Committee on Banking Regulations and Supervisory
Practices entitled "International Convergence of Capital Measurement and Capital
Standards", or the adoption after the date hereof of any other law, rule,
regulation or guideline regarding capital adequacy, or any change in any of the
foregoing or in the interpretation or administration of any of the foregoing by
any Governmental Authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by any Lender (or any
lending office of such Lender) or any Lender's holding company with any request
or directive regarding capital adequacy (whether or not having the force of law)
of any such authority, central bank or comparable agency, has or would have the
effect of reducing the rate of return on such Lender's capital or on the capital
of such Lender's holding company, if any, as a consequence of this Agreement or
the Loans made by such Lender pursuant hereto to a level below that which such
Lender or such Lender's holding company could have achieved but for such
applicability, adoption, change or compliance (taking into consideration such
Lender's policies and the policies of such Lender's holding company with respect
to capital adequacy) by an amount deemed by such Lender to be material, then
from time to time the Borrower shall pay to such Lender such additional amount
or amounts as will compensate such Lender or such Lender's holding company for
any such reduction suffered.

          (c)  A certificate of a Lender setting forth such amount or amounts as
shall be necessary to compensate such Lender as specified in paragraph (a) or
(b) above, as the case may be, shall be delivered to the Borrower and shall be
conclusive absent demonstrable error.  The Borrower shall pay each Lender the
amount shown as due on any such certificate delivered by it within 10 days after
the receipt of the same.

          (d)  Except as provided in this paragraph, failure on the part of any
Lender to demand compensation for any increased costs or reduction in amounts
received or receivable or reduction in return on capital with respect to any
period shall not constitute a waiver of such Lender's right to demand
compensation with respect to such period or any other period.  The protection of
this Section shall be available to each Lender regardless of any possible
contention of the invalidity or inapplicability of the law, rule, regulation,
guideline or other change or condition which shall have occurred or been
imposed.  No Lender shall be entitled to compensation under this Section 2.14
for any costs incurred or reductions suffered with respect to any date unless it
shall have notified the Borrower that it will demand compensation for such costs
or reductions under paragraph (c) above not more than 60 days after the later of
(i) such date and (ii) the date on which it shall have become aware of such
costs or reductions.

          SECTION 2.15.  Change in Legality.  (a)  Notwithstanding any other
                         -------------------                                 
provision herein, if any change in any law or regulation or in the
interpretation thereof by any governmental authority charged with the
administration or interpretation thereof shall make it unlawful for any Lender
to make or maintain any Eurodollar Loan or to give effect to its obligations as
contemplated hereby with respect to any Eurodollar Loan, then, by written notice
to the Borrower and to the Administrative Agent, such Lender may:

          (i) declare that Eurodollar Loans will not thereafter be made by such
     Lender hereunder, whereupon such Lender shall not submit a Competitive Bid
     in response to a request for Eurodollar Competitive Loans and any request
     by the Borrower for a Eurodollar Standby Borrowing shall, as to such Lender
     only, be deemed a request for an ABR Borrowing unless such declaration
     shall be subsequently withdrawn (and such Lender agrees to withdraw any
     such declaration if legally permissible); and

                                                                              36

          (ii) require that all outstanding Eurodollar Loans made by it be 
     converted to ABR Loans (or in the case of a Eurodollar Competitive Loan, a
     Loan bearing interest at a rate equal to the Alternate Base Rate), as of
     the effective date of such notice as provided in paragraph (b) below.

In the event any Lender shall exercise its rights under (i) or (ii) above, all
payments and prepayments of principal which would otherwise have been applied to
repay the Eurodollar Loans that would have been made by such Lender or the
converted Eurodollar Loans of such Lender shall instead be applied to repay the
ABR Loans made by such Lender in lieu of, or resulting from the conversion of,
such Eurodollar Loans.

          (b)  For purposes of this Section 2.15, a notice to the Borrower by
any Lender shall be effective as to each Eurodollar Loan, if lawful, on the last
day of the Interest Period currently applicable to such Eurodollar Loan; in all
other cases such notice shall be effective on the date of receipt by the
Borrower.

          SECTION 2.16.  Indemnity.  The Borrower shall indemnify each Lender
                         ----------                                          
against any actual loss or expense which such Lender may sustain or incur as a
consequence of (a) any failure by the Borrower to fulfill on the date of any
borrowing hereunder the applicable conditions set forth in Article IV, (b) any
failure by the Borrower to borrow or to refinance, convert or continue any Loan
hereunder after irrevocable notice of such borrowing, refinancing or
continuation has been given pursuant to Section 2.03, 2.04 or 2.06, (c) any
payment, prepayment or conversion of a Eurodollar Loan, CD Loan or Fixed Rate
Loan required by any other provision of this Agreement or otherwise made or
deemed made, and any assignment of a Loan pursuant to  Section 2.21, on a date
other than the last day of the Interest Period applicable thereto, (d) any
default in payment or prepayment of the principal amount of any Loan or any part
thereof or interest accrued thereon, as and when due and payable (at the due
date thereof, whether by scheduled maturity, acceleration, irrevocable notice of
prepayment or otherwise) or (e) the occurrence of any Event of Default,
including, in each such case, any actual loss or reasonable expense sustained or
incurred or to be sustained or incurred in liquidating or employing deposits
from third parties acquired to effect or maintain such Loan or any part thereof
as a Eurodollar Loan, CD Loan or Fixed Rate Loan.

Such loss or reasonable expense shall include an amount equal to the excess, if
any, as reasonably determined by such Lender, of (i) its cost of obtaining the
funds for the Loan being paid, prepaid, converted, not borrowed, not refinanced,
not converted, not continued or assigned (assumed to be the LIBO Rate or
Adjusted CD Rate or, in the case of a Fixed Rate Loan, the fixed rate of
interest applicable thereto) for the period from the date of such payment,
prepayment, failure to borrow, failure to refinance, failure to convert, failure
to continue or assignment to the last day of the Interest Period for such Loan
(or, in the case of a failure to borrow, refinance, convert or continue, the
Interest Period for such Loan which would have commenced on the date of such
failure) over (ii) the amount of interest (as reasonably determined by such
Lender) that would be realized by such Lender in reemploying the funds so paid,
prepaid, not borrowed, not refinanced, not converted, not continued or assigned
for such period or Interest Period, as the case may be.  A certificate of any
Lender setting forth any amount or amounts which such Lender is entitled to
receive pursuant to this Section shall be delivered to the Borrower and shall be
conclusive absent demonstrable error.

2.15, each Standby Borrowing, each payment or prepayment of principal of any
Standby Borrowing, each payment of interest on the Standby Loans, each payment
of the Facility Fees, each reduction of the Commitments and each refinancing of
any Borrowing with a Standby Borrowing of any Type, shall be allocated pro rata
among the Lenders in accordance with their respective Commitments (or, if such
Commitments shall have expired or been terminated, in accordance with the
respective principal amounts of their outstanding Standby Loans).  Each payment
of principal of any Competitive Borrowing shall be allocated pro rata among the
Lenders participating in such Borrowing in accordance with the respective
principal amounts of their outstanding Competitive Loans comprising such
Borrowing.  Each payment of interest on any Competitive Borrowing shall be
allocated pro rata among the Lenders participating in such Borrowing in
accordance with the respective amounts of accrued and unpaid interest on their
outstanding Competitive Loans comprising such Borrowing.  For purposes of
determining (i) the aggregate available Commitments of the Lenders at any time
and (ii) the available Commitment of each Lender, each outstanding Competitive
Borrowing shall be deemed to have utilized the Commitments of the Lenders
(including those

Lenders which shall not have made Loans as part of such Competitive Borrowing)
pro rata in accordance with such respective Commitments.  Each Lender agrees
that in computing such Lender's portion of any Borrowing to be made hereunder,
the Administrative Agent may, in its discretion, round each Lender's percentage
of such Borrowing to the next higher or lower whole dollar amount.

          SECTION 2.18.  Sharing of Setoffs.  Each Lender agrees that if it
                         -------------------                               
shall, through the exercise of a right of banker's lien, setoff or counterclaim
against the Borrower, or pursuant to a secured claim under Section 506 of Title
11 of the United States Code or other security or interest arising from, or in
lieu of, such secured claim, received by such Lender under any applicable
bankruptcy, insolvency or other similar law or otherwise, or by any other means,
obtain payment (voluntary or involuntary) from the Borrower or its assets in
respect of any Standby Loan or Loans as a result of which the unpaid principal
portion of its Standby Loans shall be proportionately less than the unpaid
principal portion of the Standby Loans of any other Lender, it shall be deemed
simultaneously to have purchased from such other Lender at face value, and shall
promptly pay to such other Lender the purchase price for, a participation in the
Standby Loans of such other Lender, so that the aggregate unpaid principal
amount of the Standby Loans and participations in the Standby Loans held by each
Lender shall be in the same proportion to the aggregate unpaid principal amount
of all Standby Loans then outstanding as the principal amount of its Standby
Loans prior to such exercise of banker's lien, setoff or counterclaim or other
event was to the principal amount of all Standby Loans outstanding prior to such
exercise of banker's lien, setoff or counterclaim or other event; provided,
                                                                  -------- 
however, that, if any such purchase or purchases or adjustments shall be made
- -------                                                                      
pursuant to this Section 2.18 and the payment giving rise thereto shall
thereafter be recovered, such purchase or purchases or adjustments shall be
rescinded to the extent of such recovery and the purchase price or prices or
adjustment restored without interest.  The Borrower expressly consents to the
foregoing arrangements and agrees that any Lender holding a participation in a
Standby Loan deemed to have been so purchased may exercise any and all rights of
banker's lien, setoff or counterclaim with respect to any and all moneys owing
by the Borrower to such Lender by reason thereof as fully as if such Lender had
made a Standby Loan directly to the Borrower in the amount of such
participation.

          SECTION 2.19.  Payments.  (a)  The Borrower shall make each payment

amounts) hereunder and under each other Loan Document not later than 12:00 noon,
New York City time, on the date when due in dollars to the Administrative Agent
at its offices at 712 Main Street, Houston, Texas, in immediately available
funds.

          (b)  Whenever any payment (including principal of or interest on any
Borrowing or any Fees or other amounts) hereunder or under any other Loan
Document shall become due, or otherwise would occur, on a day that is not a
Business Day, such payment may be made on the next succeeding Business Day, and
such extension of time shall in such case be included in the computation of
interest or Fees, if applicable.

          SECTION 2.20.  Taxes.  (a)  Any and all payments by the Borrower
                         ------                                           
hereunder shall be made, in accordance with Section 2.19, free and clear of and
without deduction for any and all present or future taxes, levies, imposts,
deductions, charges or withholdings, and all liabilities with respect thereto,
                                                                              
excluding taxes, levies, imposts, deductions, charges and withholdings imposed
- ---------                                                                     
on the Administrative Agent's or any Lender's (or any transferee's or
assignee's, including a participation holder's (any such entity a "Transferee"))
net income and franchise, capital or license taxes imposed on the Administrative
Agent or any Lender (or Transferee) by the United States or any jurisdiction
under the laws of which it is organized, domiciled, resident or doing business
(other than doing business as a result of its participation in the transactions
contemplated by the Loan Documents) or any political subdivision thereof (all
such nonexcluded taxes, levies, imposts, deductions, charges, withholdings and
liabilities being hereinafter referred to as "Taxes").  If the Borrower shall be
required by law to deduct any Taxes from or in respect of any sum payable
hereunder to the Lenders (or any Transferee) or the Administrative Agent, (i)
the sum payable shall be increased by the amount necessary so that after making
all required deductions (including deductions applicable to additional sums
payable under this Section 2.20) such Lender (or Transferee) or the
Administrative Agent (as the case may be) shall receive an amount equal to the
sum it would have received had no such deductions been made, (ii) the Borrower
(or the Administrative Agent, as applicable) shall make such deductions at the
applicable rate and (iii) the Borrower (or

the Administrative Agent, as applicable) shall pay the full amount deducted to
the relevant taxing authority or other Governmental Authority in accordance with
applicable law.

          (b)  In addition, the Borrower agrees to pay any present or future
stamp or documentary taxes or any other excise or property taxes, charges or
similar levies which arise from any payment made hereunder or from the
execution, delivery or registration of, or otherwise with respect to, this
Agreement or any other Loan Document (hereinafter referred to as "Other Taxes").

          (c)  The Borrower will indemnify each Lender (or Transferee) and the
Administrative Agent for the full amount of Taxes and Other Taxes (including any
Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this
Section 2.20) paid by such Lender (or Transferee) or the Administrative Agent,
as the case may be, and any liability (including penalties, interest and
expenses) arising therefrom or with respect thereto, whether or not such Taxes
or Other Taxes were correctly or legally asserted by the relevant taxing
authority or other Governmental Authority.  Such indemnification shall be made
within 30 days after the date any Lender (or Transferee) or the Administrative
Agent, as the case may be, makes written demand therefor; provided, however,
                                                          --------  ------- 
that the Borrower shall not have any obligation to indemnify the Administrative
Agent or any Lender (or Transferee) for interest and penalties that are imposed
on the Administrative Agent or such Lender (or Transferee) with respect to the
period after the expiration of the Notice Period with respect to any Tax if such
Administrative Agent or such Lender fails to give written notice to the Borrower
within 45 days of its receipt of any written assertion by the relevant taxing
authority or other Governmental Authority that such Tax is due with respect to
the transactions contemplated by the Loan Documents (such 45 day period being
the "Notice Period" referred to above).  If a Lender (or Transferee) or the
Administrative Agent shall become aware that it is entitled to receive a refund
(or a credit against taxes not indemnifiable hereunder) in respect of Taxes or
Other Taxes, it shall promptly notify the Borrower of the availability of such
refund (or credit) and shall, within 30 days after receipt of a request by the
Borrower, apply for such refund at the Borrower's expense.  If any Lender (or
Transferee) or the Administrative Agent receives a refund (or a credit against
taxes not indemnifiable hereunder) in respect of any Taxes or Other Taxes for
which such Lender (or Transferee) or the

Administrative Agent has received payment from the Borrower hereunder it shall
promptly notify the Borrower of such refund (or credit) and shall, within 30
days after receipt of a request by the Borrower (or promptly upon receipt, if
the Borrower has requested application for such refund (or credit) pursuant
hereto), repay such refund (or credit) to the Borrower, net of all out-of-pocket
expenses (including taxes not indemnifiable hereunder, to the extent that no
deduction or credit has previously been claimed and utilized in connection
therewith by such Lender) of such Lender but including interest received from a
taxing authority or other Governmental Authority and fairly attributable to such
refund; provided that the Borrower, upon the request of such Lender (or
        --------                                                       
Transferee) or the Administrative Agent, agrees to return such refund (plus
penalties, interest or other charges) to such Lender (or Transferee) or the
Administrative Agent in the event such Lender (or Transferee) or the
Administrative Agent is required to repay such refund.  Each of the
Administrative Agent, each Lender and each Transferee, with respect to itself,
agrees to indemnify and hold harmless the Borrower (and, in the case of each
Lender and each Transferee, to indemnify and hold harmless the Administrative
Agent) from any taxes, penalties, interest and other expenses, costs and losses
incurred or payable by the Borrower (or the Administrative Agent, as applicable)
as a result of the failure of the Borrower to comply with clauses (ii) and (iii)
of Section 2.20(a) in reliance on any form or certificate provided to it by such
person pursuant to Section 2.20(f).

          (d)  Within 30 days after the date of any payment of Taxes or Other
Taxes withheld by the Borrower in respect of any payment to any Lender (or
Transferee) or the Administrative Agent, the Borrower will furnish to the
Administrative Agent, at its address referred to in Section 9.01, the original
or a certified copy of a receipt evidencing payment thereof or other customary
evidence of such payment.

          (e)  Without prejudice to the survival of any other agreement
contained herein, the agreements and obligations contained in this Section 2.20
shall survive the payment in full of the principal of and interest on all Loans
made hereunder.

          (f)  On or prior to the Closing Date (in the case of any Lender and
the Administrative Agent) and on or prior to the date any Transferee becomes a
Transferee hereunder

(in the case of any Transferee), and, upon written request of the Borrower or
the Administrative Agent, on or prior to the immediately following due date of
any payment by the Borrower hereunder, each Lender (or Transferee) which is
organized outside the United States shall deliver to the Borrower such
certificates, documents or other evidence, as required by the Code or Treasury
Regulations issued pursuant thereto, including Internal Revenue Service Form
1001 or Form 4224 and any other certificate or statement of exemption required
by Treasury Regulation Section 1.1441-1(a) or Section 1.1441-6(c) or any
subsequent version thereof, properly completed and duly executed by such Lender
(or Transferee) establishing that such payment is (i) not subject to withholding
under the Code because such payment is effectively connected with the conduct by
such Lender (or Transferee) of a trade or business in the United States or (ii)
totally exempt from United States tax under a provision of an applicable tax
treaty.  Unless the Borrower and the Administrative Agent have received forms or
other documents satisfactory to them indicating that payments hereunder and in
respect of the Loans are not subject to United States withholding tax the
Borrower or the Administrative Agent shall withhold taxes from such payments at
the applicable statutory rate in the case of payments to or for any Lender (or
Transferee) organized under the laws of a jurisdiction outside the United
States.

          (g)  The Borrower shall not be required to pay any additional amounts
to any Lender (or Transferee) in respect of United States withholding tax
pursuant to paragraph (a) above except to the extent such United States
withholding tax (a) results from (i) a change in applicable law, regulation or
official interpretation thereof or (ii) an amendment, modification or revocation
of any applicable tax treaty or a change in official position regarding the
application or interpretation thereof, in each case after the Closing Date (and,
in the case of a Transferee, after the date of assignment or transfer) or (b) in
the case of a Transferee, is imposed at a rate that does not exceed the rate
(determined at the time of transfer or assignment) of United States withholding
tax with respect to which the Borrower was required to pay to such Transferee's
transferor or assignor.

reasonable efforts (consistent with legal and regulatory restrictions) to file
any certificate or document requested by the Borrower or to change the
jurisdiction of its applicable lending office if the making of such a filing or
change would avoid the need for or reduce the amount of any such additional
amounts which may thereafter accrue and would not, in the sole determination of
such Lender, be otherwise disadvantageous to such Lender (or Transferee).

          (b)  In the event that any Lender shall have delivered a notice or
certificate pursuant to Section 2.14 or 2.15, or the Borrower shall be required
to make additional payments to any Lender under Section 2.20, the Borrower shall
have the right, at its own expense, upon notice to such Lender and the
Administrative Agent, (a) to terminate the Commitment of such Lender or (b) to
require such Lender to transfer and assign without recourse (in accordance with
and subject to the restrictions contained in Section 9.04) all its interests,
rights and obligations under this Agreement to another financial institution
acceptable to the Administrative Agent which shall assume such obligations;

rule or regulation or order of any Governmental Authority and (ii) the Borrower
or the assignee, as the case may be, shall pay to the affected Lender in
immediately available funds on the date of such termination or assignment the
principal of and interest accrued to the date of payment on the Loans made by it
hereunder and all other amounts accrued for its account or owed to it hereunder.


ARTICLE III.  REPRESENTATIONS AND WARRANTIES

          The Borrower represents and warrants to each of the Lenders that:

          (a)  The Borrower is a corporation duly incorporated, validly existing
     and in good standing under the laws of the State of Delaware.  The Borrower
     possesses all corporate powers and all other authorizations and licenses
     necessary to engage in its business and operations as now conducted, the
     failure to obtain or maintain which would result in a Material Adverse
     Effect.

          (b)  The execution, delivery and performance by the Borrower of this
     Agreement are within the

[6700-070(X)RAF/A08B.WPF/30D/4674W]
<PAGE>
 
                                                                              44

     Borrower's corporate powers, have been duly authorized by all necessary
     corporate action, and do not contravene (i) the Borrower's certificate of
     incorporation or by-laws or (ii) any law or contractual restriction binding
     on or affecting the Borrower.

          (c)  There is no authorization or approval or other action by, and no
     notice to or filing with, any Governmental Authority (including, without
     limitation, the ICC) required for the due execution, delivery and
     performance by the Borrower of this Agreement which has not been obtained
     or made, as the case may be.

          (d)  This Agreement is the legal, valid and binding obligation of the
     Borrower enforceable against the Borrower in accordance with its terms
     except as enforceability may be limited by applicable bankruptcy,
     insolvency, moratorium or other similar laws affecting the enforcement of
     creditors' rights generally or by the applicability of equitable
     principles.

          (e)   The consolidated balance sheet of the Borrower and its
     consolidated Subsidiaries as at December 31, 1993, and the related
     consolidated statements of income and cash flows for the fiscal year then
     ended, copies of which have been furnished to each Lender, fairly present
     the consolidated financial condition of the Borrower and such Subsidiaries
     as at such date and the results of their operations for the period ended on
     such date, all in accordance with GAAP consistently applied, and since
     December 31, 1993, there has been no material adverse change in such
     condition or operations.

          (f)  There is no pending or threatened action or proceeding against or
     involving the Borrower before any Governmental Authority or arbitrator
     which has a reasonable probability (taking into account the exhaustion of
     all appeals) of resulting in a Material Adverse Effect.

          (g)  The Borrower has duly paid and discharged all taxes, assessments
     and governmental charges upon it or against its properties now due and
     payable, the failure to pay which would result in a Material Adverse Effect
     unless and to the extent only that the same are being contested in good
     faith and by appropriate proceedings by the Borrower.

                                                                              45

     (h)  The Borrower has good title to its properties and assets except for
     (i) existing or future liens, security interests, mortgages, conditional
     sales arrangements and other encumbrances (including, without limitation,
     reversionary title interests) either securing Debt or other liabilities of
     the Borrower or any of its Subsidiaries or which the Borrower in its
     reasonable business judgment determines would not be reasonably expected to
     materially interfere with the railroad business or railroad operations of
     the Borrower and its Subsidiaries as conducted from time to time and (ii)
     irregularities therein which do not materially interfere with the business
     or operations of the Borrower and its Subsidiaries as conducted from time
     to time.

          (i)  No Termination Event has occurred or is reasonably expected to
     occur with respect to any Plan which, with the giving of notice or lapse of
     time, or both, would constitute an Event of Default under paragraph (g) of
     Article VII.

          (j)  The statement of assets and liabilities of each Plan covered by
     the report of Coopers & Lybrand referred to below as of December 31, 1993,
     and the statements of changes in fund balance and in financial position, or
     the statement of changes in net assets available for plan benefits, for the
     plan year then ended, reported on by Coopers & Lybrand, copies of which
     have been furnished to the Administrative Agent, fairly present the
     financial condition of such Plan as at such date and the results of
     operations of such Plan for the plan year ended on such date.

          (k)  Neither the Borrower nor any ERISA Affiliate has incurred, or is
     reasonably expected to incur, any Withdrawal Liability to any Multiemployer
     Plan which, when aggregated with all other amounts required to be paid to
     Multiemployer Plans in connection with Withdrawal Liability (as of the date
     of determination), exceeds $50,000,000.

          (l)  Neither the Borrower nor any ERISA Affiliate has received any
     notification that any Multiemployer Plan is in reorganization or has been
     terminated, within the meaning of Title IV of ERISA, and no Multiemployer
     Plan is reasonably expected to be in reorganization or to be terminated
     within the meaning

     of Title IV of ERISA, the effect of which reorganization or termination
     would be the occurrence of an Event of Default under paragraph (i) of
     Article VII.

          (m)  Neither the Borrower nor any of its Subsidiaries is engaged
     principally, or as one of its important activities, in the business of
     extending credit for the purpose of purchasing or carrying Margin Stock.
     No part of the proceeds of any Loan will be used, whether directly or
     indirectly, and whether immediately, incidentally or ultimately, for any
     purpose which entails a violation of, or which is inconsistent with, the
     provisions of the Regulations of the Board, including Regulation G, U or X.

          (n)  Neither the Borrower nor any Subsidiary is (i) an "investment
     company" as defined in, or subject to regulation under, the Investment
     Company Act of 1940 or (ii) a "holding company" as defined in, or subject
     to regulation under, the Public Utility Holding Company Act of 1935.

          (o)  The Borrower will use the proceeds of the Loans only for the
     purposes specified in the preamble to this Agreement.

          (p)  Neither the Borrower nor any of its Subsidiaries is, to the best
     of its knowledge, in violation of any law or statute, or in default with
     respect to any judgment, writ, injunction, decree, rule or regulation of
     any court or governmental agency or instrumentality, where such violation
     or default would result in a Material Adverse Effect.

          (q)  On the Closing Date, there has been no material adverse change in
     or affecting the business, assets, liabilities or operations of the
     Borrower or in the condition (financial or otherwise) or prospects of the
     Borrower from those shown in the information furnished to the Lenders prior
     to the date hereof.

          (r) To the best knowledge of the Borrower, on the Closing Date all
     insurable properties of the Borrower and each Subsidiary are adequately
     insured as part of an insurance program including risk retention and self
     insurance by financially sound and reputable insurers to such extent and
     against such risks and liabilities

     (including liability under Federal, state, local and other statutes and
     regulations relating to the environment or to employee health and safety)

          Subject to the appointment and acceptance of a successor Agent as
provided below, any Agent may resign at any time by notifying the Lenders and
the Borrower.  Upon any such resignation, the Required Lenders shall have the
right to appoint a successor.  If no successor shall have been so appointed by

reasonable allocation of expenses or other amounts referred to in this paragraph
between this Agreement and the Facility A Credit Agreement shall be conclusive
and binding for all purposes.

information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement.  Each Lender also acknowledges that it
will, independently and without reliance upon the Agents or any other Lender and
based on such documents and information as it shall from time to time deem
appropriate, continue to make its own decisions in taking or not taking action

and warrants that it is legally authorized to enter into such Assignment and
Acceptance; (iv) such assignee confirms that it has received a copy of this
Agreement, together with copies of the most recent financial statements
delivered pursuant to Section 5.03 and such other documents and information as
it has deemed appropriate to make its own credit analysis and decision to enter
into such Assignment and Acceptance;  (v) such assignee will independently and
without reliance upon the Administrative Agent, such assigning Lender or any
other Lender and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under this Agreement; (vi) such assignee appoints and
authorizes the Administrative Agent to take such action as agent on its behalf
and to exercise such powers under this Agreement as are delegated to the
Administrative Agent by the terms hereof, together with such powers as are
reasonably incidental thereto; and (vii) such assignee agrees that it will
perform in accordance with their terms all the obligations which by the terms of
this Agreement are required to be performed by it as a Lender.

          (d)  The Administrative Agent shall maintain at one of its offices in
The City of Houston a copy of each Assignment and Acceptance delivered to it and
a register for the recordation of the names and addresses of the Lenders, and
the Commitment of, and principal amount of the Loans owing to, each Lender
pursuant to the terms hereof from time to time (the "Register").  The entries in
the Register shall be conclusive in the absence of demonstrable error and the
Borrower, the Agents and the Lenders may treat each person whose name is
recorded in the Register pursuant to the terms hereof as a Lender hereunder for
all purposes of this Agreement.  The Register shall be available for inspection
by the Borrower and any Lender, at any reasonable time and from time to time
upon reasonable prior notice.

          (e)  Upon its receipt of a duly completed Assignment and Acceptance
executed by an assigning Lender and an assignee, an Administrative Questionnaire

(b) above and, if required, the written consent of the Borrower and the
Administrative Agent to such assignment, the Administrative Agent shall (i)

          (f)  Each Lender may without the consent of the Borrower or the Agents
sell participations to one or more banks or other entities in all or a portion
of its rights and obligations under this Agreement (including all or a portion
of its Commitment and the Loans owing to it); provided, however, that (i) such
                                              --------  -------               
Lender's obligations under this Agreement shall remain unchanged, (ii) such
Lender shall remain solely responsible to the other parties hereto for the
performance of such obligations, (iii) the participating banks or other entities
shall be entitled to the benefit of the cost protection provisions contained in
Sections 2.14, 2.16 and 2.20 to the same extent as if they were Lenders and (iv)
the Borrower, the Agents and the other Lenders shall continue to deal solely and
directly with such Lender in connection with such Lender's rights and
obligations under this Agreement, and such Lender shall retain the sole right to
enforce the obligations of the Borrower relating to the Loans and to approve any
amendment, modification or waiver of any provision of this Agreement (other than
amendments, modifications or waivers decreasing any fees payable hereunder or
the amount of principal of or the rate at which interest is payable on the
Loans, extending any scheduled principal payment date or date fixed for the
payment of interest on the Loans or changing or extending the Commitments).

          (g)  Any Lender or participant may, in connection with any assignment
or participation or proposed assignment or participation pursuant to this
Section 9.04, disclose to the assignee or participant or proposed assignee or
participant any information relating to the Borrower furnished to such Lender by
or on behalf of the Borrower; provided that, prior to any such disclosure of
                              --------                                      
information designated by the Borrower as confidential, each such assignee or
participant or proposed assignee or participant shall execute an agreement
whereby such assignee or participant shall agree (subject to customary
exceptions) to preserve the confidentiality of such confidential information.
It is understood that confidential information relating to the Borrower would
not ordinarily be provided in connection with assignments or participations of
Competitive Loans.

          (h)  Any Lender may at any time assign all or any portion of its
rights under this Agreement to a Federal Reserve Bank; provided that no such
                                                       --------             
assignment shall release a Lender from any of its obligations hereunder.  In
order to facilitate such an assignment to a Federal Reserve Bank, the Borrower
shall, to the extent permissible without

                                                                              69

registration under applicable regulations of the ICC, at the request of the
assigning Lender, duly execute and deliver to the assigning Lender a promissory
note or notes evidencing the Loans made to the Borrower by the assigning Lender
hereunder.

          (i)  The Borrower shall not assign or delegate any of its rights or
duties hereunder without the prior written consent of the Lenders.

          SECTION 9.05.  Expenses; Indemnity.  (a)  The Borrower agrees to pay
                         --------------------                                 
all out-of-pocket expenses incurred by the Agents in connection with the
preparation of this Agreement and the other Loan Documents or in connection with
any amendments, modifications or waivers of the provisions hereof or thereof
(whether or not the transactions hereby contemplated shall be consummated) or
incurred by the Agents or any Lender in connection with the enforcement or
protection of their rights in connection with this Agreement and the other Loan
Documents or in connection with the Loans made hereunder, including the
reasonable fees, charges and disbursements of Cravath, Swaine & Moore, counsel
for the Agents, and, in connection with any such amendment, modification or
waiver or any such enforcement or protection, the reasonable fees, charges and
disbursements of any other counsel for the Agents or any Lender.  The Borrower
further agrees that it shall indemnify the Lenders from and hold them harmless
against any documentary taxes, assessments or charges made by any Governmental
Authority by reason of the execution and delivery of this Agreement or any of
the other Loan Documents.

          (b)  The Borrower agrees to indemnify the Agents, each Lender and each
of their respective directors, officers, employees and agents (each such person
being called an "Indemnitee") against, and to hold each Indemnitee harmless
from, any and all losses, claims, damages, liabilities and related expenses,
including reasonable counsel fees, charges and disbursements, incurred by or
asserted against any Indemnitee arising out of, in any way connected with, or as
a result of (i) the execution or delivery of this Agreement or any other Loan
Document or any agreement or instrument contemplated thereby, the performance by
the parties thereto of their respective obligations thereunder or the
consummation of the transactions contemplated thereby, (ii) the use of the
proceeds of the Loans or (iii) any claim, litigation, investigation or
proceeding relating to any of the foregoing to which such Indemnitee reasonably
believes that it may

become a party, whether or not any Indemnitee is a party thereto; provided that
                                                                  --------     
such indemnity shall not, as to any Indemnitee, be available to the extent that
such losses, claims, damages, liabilities or related expenses are determined by
a court of competent jurisdiction by final and nonappealable judgment to have
resulted from the gross negligence or wilful misconduct of such Indemnitee.

          (c)  The provisions of this Section 9.05 shall remain operative and in
full force and effect regardless of the expiration of the term of this
Agreement, the consummation of the transactions contemplated hereby, the
repayment of any of the Loans, the invalidity or unenforceability of any term or
provision of this Agreement or any other Loan Document, or any investigation
made by or on behalf of the Agents or any Lender.  All amounts due under this
Section 9.05 shall be payable on written demand therefor.

          SECTION 9.06.  Right of Setoff.  If an Event of Default shall have
                         ----------------                                   
occurred and be continuing, each Lender is hereby authorized at any time and
from time to time, to the fullest extent permitted by law, to set off and apply
any and all deposits (general or special, time or demand, provisional or final)
at any time held and other indebtedness at any time owing by such Lender to or
for the credit or the account of the Borrower against any of and all the
obligations of the Borrower now or hereafter existing under this Agreement and
other Loan Documents held by such Lender, irrespective of whether or not such
Lender shall have made any demand under this Agreement or such other Loan
Document and although such obligations may be unmatured.  Each Lender agrees
promptly to notify the Borrower after any such setoff and application made by
such Lender, provided that the failure to give such notice shall not affect the
             --------                                                          
validity of such setoff and application.  The rights of each Lender under this
Section are in addition to other rights and remedies (including other rights of
setoff) which such Lender may have.

          SECTION 9.07.  Applicable Law.  THIS AGREEMENT AND THE OTHER LOAN
                         ---------------                                   
DOCUMENTS SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE
STATE OF NEW YORK.

          SECTION 9.08.  Waivers; Amendment.  (a)  No failure or delay of the
                         -------------------                                 
Agents or any Lender in exercising any power or right hereunder shall operate as
a waiver thereof, nor shall any single or partial exercise of any such right or
power, or any abandonment or discontinuance of

steps to enforce such a right or power, preclude any other or further exercise
thereof or the exercise of any other right or power.  The rights and remedies of
the Agents and the Lenders hereunder and under the other Loan Documents are
cumulative and are not exclusive of any rights or remedies which they would
otherwise have.  No waiver of any provision of this Agreement or any other Loan
Document or consent to any departure by the Borrower therefrom shall in any
event be effective unless the same shall be permitted by paragraph (b) below,
and then such waiver or consent shall be effective only in the specific instance
and for the purpose for which given.  No notice or demand on the Borrower in any
case shall entitle the Borrower to any other or further notice or demand in
similar or other circumstances.

          (b)  Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to an agreement or agreements in writing
entered into by the Borrower and the Required Lenders; provided, however, that
                                                       --------  -------      
no such agreement shall (i) decrease the principal amount of, or extend the
maturity of or any scheduled principal payment date or date for the payment of
any interest on, any Loan, or waive or excuse any such payment or any part
thereof, or decrease the rate of interest on any Loan, without the prior written
consent of each Lender affected thereby, (ii) change or extend the Commitment or
decrease the Facility Fees of any Lender without the prior written consent of
such Lender, or (iii) amend or modify the provisions of Section 2.17, the
provisions of this Section, any provision of this agreement which by its terms
requires the consent or approval of all Lenders or the definition of "Required
Lenders", without the prior written consent of each Lender; provided further
                                                            ----------------
that no such agreement shall amend, modify or otherwise affect the rights or
duties of the Agents hereunder without the prior written consent of the Agents.

          SECTION 9.09.  Interest Rate Limitation.  Notwithstanding anything
                         -------------------------                          
herein to the contrary, if at any time the applicable interest rate, together
with all fees and charges which are treated as interest under applicable law
(collectively the "Charges"), as provided for herein or in any other document
executed in connection herewith, or otherwise contracted for, charged, received,
taken or reserved by any Lender, shall exceed the maximum lawful rate (the
"Maximum Rate") which may be contracted for, charged, taken, received or
reserved by such Lender in accordance with applicable law, the rate of interest
payable on the Loans of such

                                                                              72

Lender, together with all Charges payable to such Lender, shall be limited to
the Maximum Rate.

          SECTION 9.10.  Entire Agreement.  This Agreement and the other Loan
                         -----------------                                   
Documents constitute the entire contract between the parties relative to the
subject matter hereof.  Any previous agreement among the parties with respect to
the subject matter hereof is superseded by this Agreement and the other Loan
Documents.  Nothing in this Agreement or in the other Loan Documents, expressed
or implied, is intended to confer upon any party other than the parties hereto
and thereto any rights, remedies, obligations or liabilities under or by reason
of this Agreement or the other Loan Documents.

          SECTION 9.11.  Severability.  In the event any one or more of the
                         -------------                                     
provisions contained in this Agreement or in any other Loan Document should be
held invalid, illegal or unenforceable in any respect, the validity, legality
and enforceability of the remaining provisions contained herein and therein
shall not in any way be affected or impaired thereby.  The parties shall
endeavor in good-faith negotiations to replace the invalid, illegal or
unenforceable provisions with valid provisions the economic effect of which
comes as close as possible to that of the invalid, illegal or unenforceable
provisions.

          SECTION 9.12.  Counterparts.  This Agreement may be executed in two or
                         -------------                                          
more counterparts, each of which shall constitute an original but all of which
when taken together shall constitute but one contract, and shall become
effective as provided in Section 9.03.

          SECTION 9.13.  Headings.  Article and Section headings and the Table
                         ---------                                            
of Contents used herein are for convenience of reference only, are not part of
this Agreement and are not to affect the construction of, or to be taken into
consideration in interpreting, this Agreement.

          SECTION 9.14.  Jurisdiction; Consent to Service of Process.  (a)  The
                         ----------------------------------- --------          
Borrower hereby irrevocably and unconditionally submits, for itself and its
property, to the nonexclusive jurisdiction of any New York State court or
Federal court of the United States of America sitting in New York City, and any
appellate court from any thereof, in any action or proceeding arising out of or
relating to this Agreement or the other Loan Documents, or for recognition or
enforcement of any judgment, and each of the parties hereto

                                                                              73

hereby irrevocably and unconditionally agrees that all claims in respect of any
such action or proceeding may be heard and determined in such New York State or,
to the extent permitted by law, in such Federal court.  Each of the parties
hereto agrees that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law.  Nothing in this Agreement shall affect any
right that any Lender may otherwise have to bring any action or proceeding
relating to this Agreement or the other Loan Documents against the Borrower or
its properties in the courts of any jurisdiction.

          (b)  The Borrower hereby irrevocably and unconditionally waives, to
the fullest extent it may legally and effectively do so, any objection which it
may now or hereafter have to the laying of venue of any suit, action or
proceeding arising out of or relating to this agreement or the other Loan
Documents in any New York State or Federal court sitting in New York City.  Each
of the parties hereto hereby irrevocably waives, to the fullest extent permitted
by law, the defense of an inconvenient forum to the maintenance of such action
or proceeding in any such court.

          (c)  Each party to this Agreement irrevocably consents to service of
process in the manner provided for notices in Section 9.01.  Nothing in this
Agreement will

[6700-070(X)RAF/A08B.WPF/30D/4674W]

affect the right of any party to this Agreement to serve process in any other
manner permitted by law.


          IN WITNESS WHEREOF, the Borrower, the Lenders, the Administrative
Agent and the CAF Agent have caused this Agreement to be duly executed by their
respective authorized officers as of the day and year first above written.

                                                                              13

        (b)  Each Lender shall make one or more Term Loans in an aggregate 
principal amount equal to its Commitment hereunder on the Funding Date by wire 
transfer of immediately available funds to the Administrative Agent in Houston, 
Texas, not later than 11:00 a.m., Houston time, and the Administrative Agent 
shall by 2:00 p.m., Houston time, credit the amounts so received to the general 
deposit account of the Borrower with the Administrative Agent or, if a Borrowing
shall not occur on such date because any condition precedent herein specified 
shall not have been met, return the amounts so received to the respective 
Lenders.  Unless the Administrative Agent shall have received notice from a 
Lender prior to the Funding Date that such Lender will not make available to the
Administrative Agent such Lender's portion of the Borrowing, the Administrative 
Agent may assume that such Lender has made such portion available to the 
Administrative Agent on the date of such Borrowing in accordance with this 
paragraph (b) and the Administrative Agent may, in reliance upon such 
assumption, make available to the Borrower on such date a corresponding amount. 
If and to the extent that such Lender shall not have made such portion available

repay to the Administrative Agent forthwith on demand such corresponding amount

(b) of this Section 2.04 and in the Register maintained by the Administrative 
Agent pursuant to Section 9.04(d) shall be prima facie evidence of the existence
and amounts of the obligations of the Borrower to which such entries relate; 
provided, however, that the failure of any Lender or the Administrative Agent to
- --------  -------
maintain or to make any entry in such records or the Register, as applicable, or
any error therein shall not in any manner affect the obligation of the Borrower 
to repay the Term Loans in accordance with the terms of this Agreement.

        SECTION 2.05.  Interest on Term Loans.  (a)  Subject to the provisions 
                       -----------------------
of Section 2.06, each Term Loan of each Lender shall bear interest (computed on 
the basis of the actual number of days elapsed over a year of 360 days) during 
any Eurodollar Period at a rate per annum equal to the LIBO Rate for the 
Interest Period in effect for such Borrowing plus the Interest Rate Margin 
applicable to such Term Loan by such Lender.

        (b)  Subject to the provisions of Section 2.06, each Term Loan of each 
Lender shall bear interest (computed on the basis of the actual number of days 
elapsed over a year of 365 or 366 days, as appropriate, when determined by 
reference to the Prime Rate and over a year of 360 days at all other times) 
during any ABR Period at a rate per annum equal to the Alternate Base Rate.

Interest Period or day within an Interest Period, as the case may be, shall be 
determined by the Administrative Agent, and such determination shall be 
conclusive absent manifest error.  The Administrative Agent shall promptly 
advise the Borrower and each Lender, as appropriate, of such determination.

        SECTION 2.06.  Default Interest.  If the Borrower shall default in the 
                       -----------------
payment of the principal of or interest on any Term Loan or any other amount 
becoming due hereunder, whether by scheduled maturity, notice of prepayment, 
acceleration or otherwise, the Borrower shall on demand from time to time from 
the Administrative Agent pay interest, to the extent permitted by law, on such 
defaulted amount up to (but not including) the date of actual payment (after as 
well as before judgment) at a rate per annum (computed on the basis of the 
actual number of days elapsed over a year of 365 or 366 days, as appropriate, 
when determined by reference to the Prime Rate and over a year of 360 days at 
all other times) equal to the Alternate Base Rate plus 1%.

        SECTION 2.07. Alternate Rate of Interest. In the event, and on each
                      ---------------------------
occasion, that on the day two Business Days prior to the commencement of any
Interest Period for a Eurodollar Borrowing the Administrative Agent shall have
determined (i) that dollar deposits in the principal amounts of the Eurodollar
Term loans comprising such Borrowing are not generally available in the London
interbank market, or (ii) that the rates at which such dollar deposits are being
offered will not adequately and fairly reflect the cost to any Lender of making
or maintaining its Eurodollar Term Loan or Loans during such Interest Period, or
(iii) that reasonable means do not exist for ascertaining the LIBO Rate, the
Administrative Agent shall, as soon as practicable thereafter, give written or
telecopy notice of such determination to the Borrower and the Lenders. In the
event of any such determination, until the Administrative Agent shall have
advised the Borrower and the Lenders that the circumstances giving rise to such
notice no longer exist, any request by the Borrower pursuant to Section 2.08 to
convert the Term Loans into Eurodollar Term Loans or to continue the Term Loans
as Eurodollar Term Loans shall be deemed to be a request for ABR Term Loans (x)
as to all Lenders, in the event the circumstances referred to in (i) or (iii)
above are applicable, or (y) as to each affected Lender, in the event only the
circumstances referred to in (ii) above are applicable. In the event the
circumstances referred to in (ii) above are applicable, all payments and

prepayments of principal which would otherwise have been made on account of the 
Eurodollar Term Loan or Loans of the affected Lender shall instead be applied to
repay the ABR Term Loan or Loans made by such Lender in lieu of such Eurodollar 
Term Loan or Loans.  Each determination by the Administrative Agent hereunder 
shall be conclusive absent demonstrable error.

        SECTION 2.08.  Conversion and Continuation of Borrowings.  The Borrower 
                       ------------------------------------------
shall have the right at any time (subject to Section 2.07) upon prior 
irrevocable notice to the Agent (i) not later than 11:00 a.m., Houston time, one
Business Day prior to conversion, to convert the Term Loans, in whole but not in

                (a) accrued interest on the Term Loans shall be paid by the
        Borrower at the time of any conversion;

                (b)  if any Eurodollar Borrowing is converted at a time other
        than the end of the Interest Period applicable thereto, the Borrower
        shall pay, upon demand, any amounts due to the Lenders pursuant to
        Section 2.12;

                (c)  the Term Loans may not be converted into or continued as
        Eurodollar Term Loans if the Interest Period with respect thereto would
        extend beyond the Maturity Date; and

                (d) if the Term Loans cannot be converted into or continued as
        Eurodollar Term Loans by reason of subparagraph (c) above they shall be
        automatically converted at the end of the Interest Period in effect into
        ABR Term Loans.

        Each notice pursuant to this Section 2.08 shall be irrevocable and shall
refer to this Agreement and specify (i) whether the Term Loans are to be

requests a conversion, the date of such conversion (which shall be a Business 
Day) and (iii) if the Term Loans are to be converted to or continued as 
Eurodollar Term Loans, the Interest Period with respect thereto.  If no Interest
Period is specified in any such notice with respect to any conversion to or 
continuation as Eurodollar Term Loans, the Borrower shall be deemed to have 
selected an Interest Period of three months' duration.  The Agent shall advise 
the other Lenders of any notice given pursuant to this Section 2.08.  If the 
Borrower shall not have given notice in accordance with this Section 2.08 to 
continue the Term Loans into a subsequent Interest Period (and shall not 
otherwise have given notice in accordance with this Section 2.08 to convert the 
Term Loans), the Term Loans shall, at the end of the Interest Period applicable 
thereto (unless repaid pursuant to the terms hereof), automatically be 
continued into a new Interest Period as ABR Term Loans.

        SECTION 2.09.  Prepayment.  (a)  The Borrower shall have the right at 
                       -----------
any time and from time to time to prepay any Borrowing, in whole or in part, 
upon giving written or telecopy notice (or telephone notice promptly confirmed 
by written or telecopy notice) to the Administrative Agent:  (i) before 11:00 
a.m., Houston time, three Business Days prior to prepayment, in the case of a 
Eurodollar Borrowing, and (ii) before 11:00 a.m., Houston time, one Business Day
prior to prepayment, in the case of an ABR Borrowing; provided, however, that 
                                                      --------  -------
each partial prepayment shall be in an amount which is an integral multiple of 
$1,000,000 and not less than $10,000,000.

        (b)  Each notice of prepayment shall specify the prepayment date and the
principal amount of the Borrowing to be prepaid, shall be irrevocable and shall 
commit the Borrower to prepay such Borrowing by the amount stated therein on the
date stated therein.  All prepayments under this Section 2.09 shall be subject 
to Section 2.12 but otherwise without premium or penalty.  All prepayments under
this Section 2.09 shall be accompanied by accrued interest on the principal 
amount being prepaid to the date of payment.

        SECTION 2.10.  Reserve Requirements; Change in Circumstances.  
                       ----------------------------------------------
        (a)  Notwithstanding any other provision herein, if after the date of
this Agreement any change in applicable law or regulation or in the
interpretation or administration thereof by any Governmental Authority charged

<PAGE>
 
                                                                              18

with the interpretation or administration thereof (whether or not having the
force of law) shall change the basis of taxation of payments to any Lender of
the principal of or interest on any Eurodollar Term Loan or Loans made by such
Lender or other amounts payable hereunder (other than changes in respect of
taxes imposed on the overall net income of such Lender by the jurisdiction in
which such Lender has its principal office or by any political subdivision or
taxing authority therein), or shall impose, modify or deem applicable any
reserve, special deposit or similar requirement against assets of, deposits with
or for the account of or credit extended by such lender, or shall impose on such
Lender or the London interbank market any other condition affecting this
Agreement or any Eurodollar Term Loan or Loans made by such Lender, and the
result of any of the foregoing shall be to increase the cost to such Lender of
making or maintaining any Eurodollar Term Loan or Loans or to reduce the amount
of any sum received or receivable by such Lender hereunder (whether of
principal, interest or otherwise) by an amount deemed by such Lender to be
material, then the Borrower will pay to such Lender upon demand such additional
amount or amounts as will compensate such Lender for such additional costs
incurred or reduction suffered. Notwithstanding the foregoing, no Lender shall
be entitled to request compensation under this paragraph with respect to its
Term Loan if such Lender shall have been aware of the change giving rise to such
request at the time it initially submitted its Commitment to make such Term Loan
or Loans pursuant to this Agreement to the Borrower.

        (b)  If any Lender shall have determined that the applicability of any
law, rule, regulation or guideline adopted pursuant to or arising out of the
July 1988 report of the Basle Committee on Banking Regulations and Supervisory
Practices entitled "International Convergence of Capital Measurement and Capital
Standards", or the adoption after the date hereof of any other law, rule,
regulation or guideline regarding capital adequacy, or any change in any of the
foregoing or in the interpretation or administration of any of the foregoing by
any Governmental Authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by any Lender (or any
lending office of such Lender) or any Lender's holding company with any request
or directive regarding capital adequacy (whether or not having the force of law)
of any such authority, central bank or comparable agency, has or would have the
effect of reducing the rate of return on such Lender's capital or on the capital
of such

<PAGE>
 
                                                                              19

Lender's holding company, if any, as a consequence of this Agreement or the Term
Loan or Loans made by such Lender pursuant hereto to a level below that which
such Lender or such Lender's holding company could have achieved but for such
applicability, adoption, change or compliance (taking into consideration such
Lender's policies and the policies of such Lender's holding company with respect
to capital adequacy) by an amount deemed by such Lender to be material, then
from time to time the Borrower shall pay to such Lender such additional amount
or amounts as will compensate such Lender or such Lender's holding company for
any such reduction suffered.

        (c)  A certificate of a Lender setting forth such amount or amounts as 
shall be necessary to compensate such Lender as specified in paragraph (a) or 
(b) above, as the case may be, shall be delivered to the Borrower and shall be 
conclusive absent demonstrable error.  The Borrower shall pay each Lender the 
amount shown as due on any such certificate delivered by it within 10 days after
the receipt of the same.

        (d) Except as provided in this paragraph, failure on the part of any
Lender to demand compensation for any increased costs or reduction in amounts
received or receivable or reduction in return on capital with respect to any
period shall not constitute a waiver of such Lender's right to demand
compensation with respect to such period or any other period. The protection of
this Section shall be available to each Lender regardless of any possible
contention of the invalidity or inapplicability of the law, rule, regulation,
guideline or other change or condition which shall have occurred or been
imposed. No Lender shall be entitled to compensation under this Section 2.10 for
any costs incurred or reductions suffered with respect to any date unless it
shall have notified the Borrower that it will demand compensation for such costs
or reductions under paragraph (c) above not more than 60 days after the later of
(i) such date and (ii) the date on which it shall have become aware of such
costs or reductions.

        SECTION 2.11.  Change in Legality.  (a)  Notwithstanding any other 
                       -------------------
provision herein, if any change in any law or regulation or in the 
interpretation thereof by any Governmental Authority charged with the 
administration or interpretation thereof shall make it unlawful for any Lender 
to make or maintain any Eurodollar Term Loan or Loans or to give effect to its 
obligations as contemplated hereby with

<PAGE>
 
                                                                              20

respect to any Eurodollar Term Loan or Loans, then, by written notice to the 
Borrower and to the Administrative Agent, such Lender may:

                (i) declare that Eurodollar Term Loans will not thereafter be
        made by such Lender hereunder, whereupon any request by the Borrower for
        a Eurodollar Borrowing shall, as to such Lender only, be deemed a
        request for an ABR Borrowing unless such declaration shall be
        subsequently withdrawn (and such Lender agrees to withdraw any such
        declaration if legally permissible); and

                (ii) require that all outstanding Eurodollar Term Loans made by
        it be converted to ABR Term Loans, as of the effective date of such
        notice as provided in paragraph (b) below.

In the event any Lender shall exercise its rights under (i) or (ii) above, all 
payments and prepayments of principal which would otherwise have been applied to
repay the Eurodollar Term Loan or Loans that would have been made by such Lender
or the converted Eurodollar Term Loan or Loans of such Lender shall instead be 
applied to repay the ABR Term Loan or Loans made by such Lender in lieu of, or 
resulting from the conversion of, such Eurodollar Term Loan or Loans.

        (b)  For purposes of this Section 2.11, a notice to the Borrower by any 
Lender shall be effective as to such Lender's Eurodollar Term Loan or Loans, if 
lawful, on the last day of the Interest Period currently applicable to such 
Eurodollar Term Loan or Loans; in all other cases such notice shall be effective
on the date of receipt by the Borrower.

        SECTION 2.12.  Indemnity.  The Borrower shall indemnify each Lender 
                       ----------
against any actual loss or expense which such Lender may sustain or incur as a 
consequence of (a) any failure by the Borrower to fulfill on the Funding Date 
hereunder the applicable conditions set forth in Article IV, (b) any failure by 
the Borrower to borrow on the Funding Date or to convert or continue any Term 
Loan hereunder after irrevocable notice of such conversion or continuation has 
been given pursuant to Section 2.08, (c) any payment, prepayment or conversion 
of a Eurodollar Term Loan required by any other provision of this Agreement or 
otherwise made or deemed made, and any assignment of a

                                                                              21

Term Loan pursuant to Section 2.17, on a date other than the last day of the
Interest Period applicable thereto, (d) any default in payment or prepayment of
the principal amount of any Term Loan or any part thereof or interest accrued
thereon, as and when due and payable (at the due date thereof, whether by
scheduled maturity, acceleration, irrevocable notice of prepayment or otherwise)
or (e) the occurrence of any Event of Default, including, in each such case, any
actual loss or reasonable expense sustained or incurred or to be sustained or
incurred in liquidating or employing deposits from third parties acquired to
effect or maintain such Term Loan or any part thereof as a Eurodollar Term Loan.
Such loss or reasonable expense shall include an amount equal to the excess, if
any, as reasonably determined by such Lender, of (i) its cost of obtaining the
funds for the Term Loan being paid, prepaid, converted, not borrowed, not
refinanced, not converted, not continued or assigned (assumed to be the LIBO
Rate) for the period from the date of such payment, prepayment, failure to
borrow, failure to convert, failure to continue or assignment to the last day of
the Interest Period for such Term Loan (or, in the case of a failure to borrow,
convert or continue, the Interest Period for such Term Loan which would have
commenced on the date of such failure) over (ii) the amount of interest (as
reasonably determined by such Lender) that would be realized by such Lender in
reemploying the funds so paid, prepaid, not borrowed, not refinanced, not
converted, not continued or assigned for such period or Interest Period, as the
case may be. A certificate of any Lender setting forth any amount or amounts
which such Lender is entitled to receive pursuant to this Section shall be
delivered to the Borrower and shall be conclusive absent demonstrable error.

        SECTION 2.13.  Pro Rata Treatment.  Except as required under Section 
                       -------------------
2.11, (a) each Borrowing and each payment or prepayment of principal of any 
Borrowing shall be allocated pro rata among the Lenders in accordance with their
respective Commitments (or, if such Commitments shall have expired or been 
terminated, in accordance with the respective principal amounts of their 
outstanding Term Loans), and (b) each payment of interest on the Term Loans 
shall be allocated pro-rata among the Lenders in accordance with the respective 
amounts of interest accrued on their Term Loans and not yet paid.

        SECTION 2.14.  Sharing of Setoffs.  Each Lender agrees that if it shall,
                       ------------------- 
through the exercise of a right of banker's lien, setoff or counterclaim against
the Borrower,

                                                                              22

or pursuant to a secured claim under Section 506 of Title 11 of the United 
States Code or other security or interest arising from, or in lieu of, such 
secured claim, received by such Lender under any applicable bankruptcy, 
insolvency or other similar law or otherwise, or by any other means, obtain 
payment (voluntary or involuntary) from the Borrower or its assets in respect of
its Term Loan or Loans as a  result of which the unpaid principal portion of its
Term Loan or Loans shall be proportionately less than the unpaid principal 
portion of the Term Loans of any other Lender, it shall be deemed simultaneously
to have purchased from such other Lender at face value, and shall promptly pay 
to such other Lender the purchase price for, a participation in the Term Loan or
Loans of such other Lender, so that the aggregate unpaid principal amount of the
Term Loan or Loans and participations in the Term Loan or Loans held by each 
Lender shall be in the same proportion to the aggregate unpaid principal 
amount of all Term Loans then outstanding at the principal amount of its Term 
Loan or Loans prior to such exercise of banker's lien, setoff or counterclaim 
or other event was to the principal amount of all Term Loans outstanding prior 
to such exercise of banker's lien, setoff or counterclaim or other event; 
provided, however, that, if any such purchase or purchases or adjustments shall 
- --------  -------
be made pursuant to this Section 2.14 and the payment giving rise thereto shall
thereafter be recovered, such purchase or purchases or adjustments shall be
rescinded to the extent of such recovery and the purchase price or prices or
adjustment restored without interest. The Borrower expressly consents to the
foregoing arrangements and agrees that any Lender holding a participation in any
Term Loan or Loans deemed to have been so purchased may exercise any and all
rights of banker's lien, setoff or counterclaim with respect to any and all
moneys owing by the Borrower to such Lender by reason thereof as fully as if
such Lender had made a Term Loan or Loans directly to the Borrower in the amount
of such participation.

        SECTION 2.15.  Payments.  (a) The Borrower shall make each payment 
                       ---------
(including principal of or interest on any Borrowing or any Fees or other 
amounts) hereunder and under each other Loan Document not later than 11:00 a.m.,
Houston time, on the date when due in dollars to the Administrative Agent at its
offices at 712 Main Street, Houston, Texas, in immediately available funds.

        (b)  Whenever any payment (including principal of or interest on any 
Borrowing or any Fees or other amounts)

<PAGE>
 
                                                                              23

hereunder or under any other Loan Document shall become due, or otherwise would
occur, on a day that is not a Business Day, such payment may be made on the next
succeeding Business Day, and such extension of time shall in such case be
included in the computation of interest or Fees, if applicable.

        SECTION 2.16. Taxes. (a) Any and all payments by the Borrower hereunder
                      ------ 
shall be made, in accordance with Section 2.15, free and clear of and without
deduction for any and all present or future taxes, levies, imposts, deductions,
charges or withholdings, and all liabilities with respect thereto, excluding
                                                                   ---------
taxes, levies, imposts, deductions, charges and withholdings imposed on the
Administrative Agent's or any Lender's (or any transferee's or assignee's,
including a participation holder's (any such entity a "Transferee")) net income
and franchise, capital or license taxes imposed on the Administrative Agent or
any Lender (or Transferee) by the United States or any jurisdiction under the
laws of which it is organized, domiciled, resident or doing business (other than
doing business as a result of its participation in the transactions contemplated
by the Loan Documents) or any political subdivision thereof (all such
nonexcluded taxes, levies, imposts, deductions, charges, withholdings and
liabilities being hereinafter referred to as "Taxes"). If the Borrower shall be
required by law to deduct any Taxes from or in respect of any sum payable
hereunder to the Lenders (or any Transferee) or the Administrative Agent, (i)
the sum payable shall be increased by the amount necessary so that after making
all required deductions (including deductions applicable to additional sums
payable under this Section 2.16) such Lender (or Transferee) or the
Administrative Agent (as the case may be) shall receive an amount equal to the
sum it would have received had no such deductions been made, (ii) the Borrower
(or the Administrative Agent, as applicable) shall make such deductions at the
applicable rate and (iii) the Borrower (or the Administrative Agent, as
applicable) shall pay the full amount deducted to the relevant taxing authority
or other Governmental Authority in accordance with applicable law.

        (b)  In addition, the Borrower agrees to pay any present or future stamp
or documentary taxes or any other excise or property taxes, charges or similar 
levies which arise from any payment made hereunder or from the execution, 
delivery or registration of, or otherwise with respect to,

<PAGE>
 
                                                                              24

this Agreement or any other Loan Document (hereinafter referred to as "Other 
Taxes").

        (c)  The Borrower will indemnify each Lender (or Transferee) and the 
Administrative Agent for the full amount of Taxes and Other Taxes (including any
Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this
Section 2.16) paid by such Lender (or Transferee) or the Administrative Agent,
as the case may be, and any liability (including penalties, interest and
expenses) arising therefrom or with respect thereto, whether or not such Taxes
or Other Taxes were correctly or legally asserted by the relevant taxing
authority or other Governmental Authority. Such indemnification shall be made
within 30 days after the date any Lender (or Transferee) or the Administrative
Agent, as the case may be, makes written demand therefor; provided, however,
                                                          --------  -------
that the Borrower shall not have any obligation to indemnify the Administrative
Agent or any Lender (or Transferee) for interest and penalties that are imposed
on the Administrative Agent or such Lender (or Transferee) with respect to the
period after the expiration of the Notice Period with respect to any Tax if such
Administrative Agent or such Lender fails to give written notice to the Borrower
within 45 days of its receipt of any written assertion by the relevant taxing
authority or other Governmental Authority that such Tax is due with respect to
the transactions contemplated by the Loan Documents (such 45 day period being
the "Notice Period" referred to above). If a Lender (or Transferee) or the
Administrative Agent shall become aware that it is entitled to receive a refund
(or a credit against taxes not indemnifiable hereunder) in respect of Taxes or
Other Taxes, it shall promptly notify the Borrower of the availability of such
refund (or credit) and shall, within 30 days after receipt of a request by the
Borrower, apply for such refund at the Borrower's expense. If any Lender (or
Transferee) or the Administrative Agent receives a refund (or a credit against
taxes not indemnifiable hereunder) in respect of any Taxes or Other Taxes for
which such Lender (or Transferee) or the Administrative Agent has received
payment from the Borrower hereunder it shall promptly notify the Borrower of
such refund (or credit) and shall, within 30 days after receipt or a request by
the Borrower (or promptly upon receipt, if the Borrower has requested
application for such refund (or credit) pursuant thereto), repay such refund (or
credit) to the Borrower, net of all out-of-pocket expenses (including taxes not
indemnifiable hereunder, to the extent that no deduction or credit has
previously been claimed and utilized

<PAGE>
 
                                                                              25

in connection therewith by such Lender) of such Lender but including interest 
received from a taxing authority or other Governmental Authority and fairly 
attributable to such refund; provided that the Borrower, upon the request of 
                             --------
such Lender (or Transferee) or the Administrative Agent, agrees to return such 
refund (plus penalties, interest or other charges) to such Lender (or 
Transferee) or the Administrative Agent in the event such Lender (or Transferee)
or the Administrative Agent is required to repay such refund.  Each of the 
Administrative Agent, each Lender and each Transferee, with respect to itself, 
agrees to indemnify and hold harmless the Borrower (and, in the case of each 
Lender and each Transferee, to indemnify and hold harmless the Administrative 
Agent) from any taxes, penalties, interest and other expenses, costs and losses 
incurred or payable by the Borrower (or the Administrative Agent, as applicable)
as a result of the failure of the Borrower to comply with clauses (ii) and (iii)
of Section 2.16(a) in reliance on any form or certificate provided to it by such
person pursuant to Section 2.16(f).

        (d)  Within 30 days after the date of any payment of Taxes or Other 
Taxes withheld by the Borrower in respect of any payment to any Lender (or 
Transferee) or the Administrative Agent, the Borrower will furnish to the  
Administrative Agent, at its address referred to in Section 9.01, the original 
of a certified copy of a receipt evidencing payment thereof or other customary 
evidence of such payment.

        (e)  Without prejudice to the survival of any other agreement contained 
herein, the agreements and obligations contained in this Section 2.16 shall 
survive the payment in full of the principal of and interest on all Term Loans 
made hereunder.

        (f)  On or prior to the Closing Date (in the case of any Lender and the 
Administrative Agent) and on or prior to the date any Transferee becomes a 
Transferee hereunder (in the case of any Transferee), and, upon written request 
of the Borrower or the Administrative Agent, on or prior to the immediately 
following due date of any payment by the Borrower hereunder, each Lender (or 
Transferee) which is organized outside the United States shall deliver to the 
Borrower such certificates, documents or other evidence, as required by the Code
or Treasury Regulations issued pursuant thereto, including Internal Revenue 
Service Form 1001 or Form 4224 and any other certificate or statement of

<PAGE>
 
                                                                              26

exemption required by Treasury Regulation Section 1.1441-1(a) or Section 
1.1441-6(c) or any subsequent version thereof, properly completed and duly 
executed by such Lender (or Transferee) establishing that such payment is (i) 
not subject to withholding under the Code because such payment is effectively 
connected with the conduct by such Lender (or Transferee) of a trade or business
in the United States or (ii) totally exempt from United States tax under a 
provision of an applicable tax treaty.  Unless the Borrower and the 
Administrative Agent have received forms or other documents satisfactory to them
indicating that payments hereunder and in respect of the Term Loans are not 
subject to United States withholding tax the Borrower or the Administrative 
Agent shall withhold taxes from such payments at the applicable statutory rate 
in the case of payments to or for any Lender (or Transferee) organized under the
laws of a jurisdiction outside the United States.

        (g)  The Borrower shall not be required to pay any additional amounts to
any Lender (or Transferee) in respect of United States withholding tax pursuant 
to paragraph (a) above except to the extent such United States withholding tax 
(a) results from (i) a change in applicable law, regulation or official 
interpretation thereof or (ii) an amendment, modification or revocation of any 
applicable tax treaty or a change in official position regarding the application
or interpretation thereof, in each case after the Closing Date (and, in the case
of a Transferee, after the date of assignment or transfer) or (b) in the case of
a Transferee, is imposed at a rate that does not exceed the rate (determined at 
the time of transfer or assignment) of United States withholding tax with 
respect to which the Borrower was required to pay to such Transferee's 
transferor or assignor.

        SECTION 2.17.  Assignment or Prepayment of Term Loans Under Certain 
                       ----------------------------------------------------
Circumstances.  (a)  Any Lender (or Transferee) claiming any additional amounts 
- --------------
payable pursuant to Section 2.10 or Section 2.16 shall use reasonable efforts 
(consistent with legal and regulatory restrictions) to file any certificate or 
document requested by the Borrower or to change the jurisdiction of its 
applicable lending office if the making of such a filing or change would avoid 
the need for or reduce the amount of any such additional amounts which may 
thereafter accrue and would not, in the sole determination of such Lender, be 
otherwise disadvantageous to such Lender (or Transferee).

        (b)  In the event that any Lender shall have delivered a notice or 
certificate pursuant to Section 2.10 or 2.11, or the Borrower shall be required 
to make additional payments to any Lender under Section 2.16, the Borrower shall
have the right, at its own expense, upon notice to such Lender and the 
Administrative Agent, (a) to prepay the Term Loan or Loans of such Lender or (b)
to require such  Lender to transfer and assign without recourse (in accordance 
with and subject to the restrictions contained in Section 9.04) all its 
interests, rights and obligations under this Agreement to another financial 
institution acceptable to the Administrative Agent which shall assume such 
obligations; provided that (i) no such prepayment or assignment shall conflict 
             --------
with any law, rule or regulation or order of any Governmental Authority and (ii)
the Borrower or the assignee, as the case may be, shall pay to the affected 
Lender in immediately available funds on the date of such prepayment or 
assignment the principal of and interest accrued to the date of payment on the 
Term Loan or Loans made by it hereunder and all other amounts accrued for its 
account or owed to it hereunder.


ARTICLE III.  REPRESENTATIONS AND WARRANTIES

        The Borrower represents and warrants to each of the Lenders that:

               (a) The Borrower is a corporation duly incorporated, validly
        existing and in good standing under the laws of the State of Delaware.
        The Borrower possesses all corporate powers and all other authorizations
        and licenses necessary to engage in its business and operations as now
        conducted, the failure to obtain or maintain which would result in a
        Material Adverse Effect.

               (b) The execution, delivery and performance by the Borrower of
        this Agreement are within the Borrower's corporate powers, have been
        duly authorized by all necessary corporate action, and do not contravene
        (i) the Borrower's certificate of incorporation or by-laws of (ii) any
        law or contractual restriction binding on or affecting the Borrower.

               (c) There is no authorization or approval or other action by,
        and no notice to or filing with, any Governmental Authority (including,
        without limitation,

<PAGE>
 
                                                                              28

the ICC) required for the due execution, delivery and performance by the 
Borrower of this Agreement which has not been obtained or made, as the case may 
be.

        (d)  This Agreement is the legal, valid and binding obligation of the 
Borrower enforceable against the Borrower in accordance with its terms except as
enforceability may be limited by applicable bankruptcy, insolvency, moratorium 
or other similar laws affecting the enforcement of creditors' rights generally 
or by the applicability of equitable principles.

        (e)  The consolidated balance sheet of the Borrower and its consolidated
Subsidiaries as at December 31, 1993, and as at June 30, 1994, and the related 
consolidated statements of income and cash flows for the fiscal year then ended,
copies of which have been furnished to each Lender, fairly present the 
consolidated financial condition of the Borrower and such Subsidiaries as at 
such date and the results of their operations for the period ended on such date,
all in accordance with GAAP consistently applied, and since December 31, 1993, 
there has been no material adverse change in such condition or operations.

        (f)  There is no pending or threatened action or proceeding against or 
involving the Borrower before any Governmental Authority or arbitrator which has
a reasonable probability (taking into account the exhaustion of all appeals) of 
resulting in a Material Adverse Effect.

        (g)  The Borrower has duly paid and discharged all taxes, assessments 
and governmental charges upon it or against its properties now due and payable, 
the failure to pay which would result in a Material Adverse Effect unless and to
the extent only that the same are being contested in good faith and by 
appropriate proceedings by the Borrower.

        (h)  The Borrower has good title to its properties and assets except for
(i) existing or future liens, security interests, mortgages, conditional sales 
arrangements and other encumbrances (including, without limitation, reversionary
title interests) either securing Debt or other liabilities of the Borrower or 
any of its Subsidiaries or which the Borrower in its reasonable business 
judgment determines would not be

                                                                              29

reasonably expected to materially interfere with the railroad business or 
railroad operations of the Borrower and its Subsidiaries as conducted from time 
to time and (ii) irregularities therein which do not materially interfere with 
the business or operations of the Borrower and its Subsidiaries as conducted 
from time to time.

        (i)  No Termination Event has occurred or is reasonably expected to 
occur with respect to any Plan which, with the giving of notice or lapse of 
time, or both, would constitute an Event of Default under paragraph (g) of 
Article VII.

        (j)  The statement of assets and liabilities of each Plan covered by the
report of Coopers & Lybrand referred to below as of December 31, 1993, and the 
statements of changes in fund balance and in financial position, or the 
statement of changes in net assets available for plan benefits, for the plan 
year then ended, reported on by Coopers & Lybrand, copies of which have been 
furnished to the Administrative Agent, fairly present the financial condition of
such Plan as at such date and the results of operations of such Plan for the 
plan year ended on such date.

        (k) Neither the Borrower nor any ERISA Affiliate has incurred, or is
reasonably expected to incur, any Withdrawal Liability to any Multiemployer Plan
which, when aggregated with all other amounts required to be paid to
Multiemployer Plans in connection with Withdrawal Liability (as of the date of
determination), exceeds $50,000,000.

        (l) Neither the Borrower nor any ERISA Affiliate has received any
notification that any Multiemployer Plan is in reorganization or has been
terminated, within the meaning of Title IV of ERISA, and no Multiemployer Plan
is reasonably expected to be in reorganization or to be terminated within the
meaning of Title IV of ERISA, the effect of which reorganization or termination
would be the occurrence of an Event of Default under paragraph (i) of
Article VII.

        (m)  Neither the Borrower nor any of its Subsidiaries is engaged 
principally, or as one of its important activities, in the business of extending


<PAGE>
 
                                                                              30
 
     credit for the purpose of purchasing or carrying Margin Stock. No part of
     the proceeds of any Term Loan will be used, whether directly or indirectly,
     and whether immediately, incidentally or ultimately, for any purpose which
     entails a violation of, or which is inconsistent with, the provisions of
     the Regulations of the Board, including Regulation G, U or X.

        (n) Neither the Borrower nor any Subsidiary is (i) an "investment
     company" as defined in, or subject to regulation under, the Investment
     Company Act of 1940 or (ii) a "holding company" as defined in, or subject
     to regulation under, the Public Utility Holding Company Act of 1935.

        (o)  The Borrower will use the proceeds of the Term Loans only for the 
     purpose specified in the preamble to this Agreement.

        (p)  Neither the Borrower nor any of its Subsidiaries is, to the best of
     its knowledge, in violation of any law or statute, or in default with
     respect to any judgment, writ, injunction, decree, rule or regulation of
     any court or governmental agency or instrumentality, where such violation
     or default would result in a Material Adverse Effect.

        (q)  On the Closing Date, there has been no material adverse change in 
     or affecting the business, assets, liabilities or operations of the
     Borrower or in the condition (financial or otherwise) or prospects of the
     Borrower from those shown in the information furnished to the Lenders prior
     to the date hereof.

        (r)  To the best knowledge of the Borrower, on the Closing Date all 
     insurable properties of the Borrower and each Subsidiary are adequately
     insured as part of an insurance program including risk retention and self
     insurance by financially sound and reputable insurers to such extent and
     against such risks and liabilities (including liability under Federal,
     state, local and other statutes and regulations relating to the environment
     or to employee health and safety) as is customary with companies similarly
     situated and in the same or similar businesses.

Lenders, without hereby limiting any implied authority, (a) to receive on behalf

all other amounts due to the Lenders hereunder, and promptly to distribute to
each Lender its proper share of each payment so received; (b) to give notice on

in this Agreement of which the Administrative Agent has actual knowledge
acquired in connection with its agency hereunder; and (c) to distribute to each

by the Borrower pursuant to this Agreement as received by the Administrative
Agent.

         Neither the Agent nor any of its directors, officers, employees or
agents shall be liable as such for any action taken or omitted by any of them
except for its, his or her own gross negligence or wilful misconduct, or be
responsible for any warranty or representation herein or the contents of any
document delivered in connection herewith, or be required to ascertain or to
make any inquiry concerning the performance or observance by the Borrower of any
of the terms, conditions, covenants or agreements contained in any Loan
Document other than those expressly provided for herein. The Agent shall not be
responsible to the Lenders for the due execution, genuineness, validity,
enforceability or effectiveness (other than against the Agent) of this Agreement
or any other Loan Documents or other instruments or agreements. The Agent shall
in all cases be fully protected in acting, or refraining from acting, in
accordance with written instructions signed by the Required Lenders and, except
as otherwise specifically provided herein, such instructions and any action or
inaction pursuant thereto shall be binding on all the Lenders. The Agent shall,
in the absence of knowledge to the contrary, be entitled to rely on any
instrument or document believed by it in good faith to be genuine and correct
and to have been signed or sent by the proper person or persons. Neither the
Agent nor any of its directors, officers, employees or agents shall have any
responsibility to the Borrower on account of the failure of or delay in
performance or breach by any Lender of any of its obligations hereunder or to
any Lender on account of the failure of or delay in performance or breach by any

                                                                              45

and shall be entitled to rely upon the advice of legal counsel reasonably 
selected by them with respect to all matters arising hereunder and shall not be 
liable for any action taken or suffered in good faith by it in accordance with 
the advice of such counsel.

        The Lenders hereby acknowledge that the Agent shall be under no duty to 
take any discretionary action permitted to be taken by it pursuant to the 
provisions of this Agreement unless it shall be requested in writing to do so by
the Required Lenders.

        Subject to the appointment and acceptance of a successor Agent as
provided below, the Agent may resign at any time by notifying the Lenders and
the Borrower. Upon any such resignation, the Required Lenders shall have the
right to appoint a successor. If no successor shall have been so appointed by

after the retiring Agent may, on behalf of the Lenders, appoint a successor
Agent which shall be a bank with an office in the United States, having a
combined capital and surplus of at least $50,000,000 or an Affiliate of any such
bank. Upon the acceptance of any appointment as Agent hereunder by a successor
bank, such successor shall succeed to and become vested with all the rights,
powers, privileges and duties of the retiring Agent and the retiring Agent shall
be discharged from its duties and obligations hereunder. After the Agent's
resignation hereunder, the provisions of this Article and Section 9.05 shall
continue in effect for its benefit in respect of any actions taken or omitted to
be taken by it while it was acting as Agent.

        With respect to the Term Loans made by it hereunder, the Agent in its 
individual capacity and not as Agent shall have the same rights and powers as 
any other Lender and may exercise the same as though it were not the Agent, and
the Agent and its Affiliates may accept deposits from, lend money to and 
generally engage in any kind of business with the Borrower or any Subsidiary or 
other Affiliate thereof as if it were not the Agent.

for services rendered on behalf of the Lenders, which shall not have been 
reimbursed by the Borrower and (ii) to indemnify and hold harmless the Agent and
any of its directors, officers, employees or agents, on demand, in the amount of
such pro rata share, from and against any and all liabilities, taxes, 
obligations, losses, damages, penalties, actions, judgments, suits, costs, 
expenses or disbursements of any kind or nature whatsoever which may be imposed 
on, incurred by or asserted against it in its capacity as the Agent or any of 
them in any way relating to or arising out of this Agreement or any other Loan 
Document or any action taken or omitted by it or any of them under this 
Agreement or any other Loan Document, to the extent the same shall not have been
reimbursed by the Borrower; provided that no Lender shall be liable to the Agent
                            --------
for any portion of such liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements resulting from the
gross negligence or wilful misconduct of the Agent or any of its directors,
officers, employees or agents.

upon the Agent or any other Lender and based on such documents and information
as it has deemed appropriate, made its own credit analysis and decision to enter
into this Agreement. Each Lender also acknowledges that it will, independently
and without reliance upon the Agent or any other Lender and based on such
documents, and information as it shall from time to time deem appropriate,
continue to make its own decisions in taking or not taking action under or based

Agreement, the consummation of the transactions contemplated hereby, the 
repayment of any of the Term Loans, the invalidity or unenforceability of any

the fullest extent permitted by law, to set off and apply any and all deposits 
(general or special, time or demand, provisional or final) at any time held and 
other indebtedness at any time owing by such Lender to or for the credit or the 
account of the Borrower against any of and all the obligations of the Borrower 
now or hereafter existing under this Agreement and other Loan Documents held by 
such lender, irrespective of whether or not such Lender shall have made any 
demand under this Agreement or such other Loan Document and although such 
obligations may be unmatured. Each Lender agrees promptly to notify the Borrower
after any such setoff and application made by such lender, provided that the 
                                                           --------
failure to give such notice shall not affect the validity of such setoff and 
application. The rights of each lender under this Section are in addition to 
other rights and remedies (including other rights of setoff) which such Lender 
may have.

        SECTION 9.07. APPLICABLE LAW. THIS AGREEMENT AND THE OTHER LOAN 
                      ---------------
DOCUMENTS SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE 
STATE OF NEW YORK.

        SECTION 9.08.  Waivers; Amendment. (a) No failure or delay of the Agent 
                       -------------------
or any lender in exercising any power or right hereunder shall operate as a
waiver thereof, nor shall any single or partial exercise of any such right or
power, or any abandonment or discontinuance of steps to enforce such a right or
power, preclude any other or further exercise thereof or the exercise of any
other right or power. The rights and remedies of the Agent and the Lenders
hereunder and under the other Loan Documents are cumulative and are not
exclusive of any rights or remedies which they would otherwise have. No waiver
of any provision of this Agreement or any other Loan Document or consent to any
departure by the Borrower therefrom shall in any event be effective unless the
same shall be permitted by paragraph (b) below, and then such waiver or consent
shall be effective only in the specific instance and for the purpose for which
given. No notice or demand on the Borrower in any case shall entitle the
Borrower to any other or further notice or demand in similar or other
circumstances.

        (b)  Neither this Agreement nor any provision hereof may be waived, 
amended or modified except pursuant to an agreement or agreements in writing 
entered into by the Borrower and the Required Lenders; provided, however, that 
                                                       --------  -------
no such agreement shall (i) decrease the principal amount of, or extend the 
maturity of or any scheduled principal

                                                                              54

payment date or date for the payment of any interest on, any Term Loan, or waive
or excuse any such payment or any part thereof, or decrease the rate of interest
on any Term Loan, without the prior written consent of each Lender affected 
thereby, or (ii) amend or modify the provisions of Section 2.13, the provisions 
of this Section, any provision of this agreement which by its terms requires the
consent or approval of all Lenders or the definition of "Required Lenders", 
without the prior written consent of each Lender; provided further that no such
                                                  ----------------
agreement shall amend, modify or otherwise affect the rights or duties of the 
Agent hereunder without the prior written consent of the Agent.

        SECTION 9.09. Interest Rate Limitation. Notwithstanding anything herein
                      -------------------------
to the contrary, if at any time the applicable interest rate, together with all 
fees and charges which are treated as interest under applicable law 
(collectively the "Charges"), as provided for herein or in any other document 
executed in connection herewith, or otherwise contracted for, charged, received,
taken or reserved by any Lender, shall exceed the maximum lawful rate (the
"Maximum Rate") which may be contracted for, charged, taken, received or
reserved by such Lender in accordance with applicable law, the rate of interest
payable on the Term Loan or Loans of such Lender, together with all Charges
payable to such Lender, shall be limited to the Maximum Rate.

        SECTION 9.10. Entire Agreement. This Agreement and the other Loan 
                      -----------------
Documents constitute the entire contract between the parties relative to the
subject matter hereof. Any previous agreement among the parties with respect to 
the subject matter hereof is superseded by this Agreement and the other Loan 
Documents. Nothing in this Agreement or in the other Loan Documents, expressed 
or implied, is intended to confer upon any party other than the parties hereto 
and thereto any rights, remedies, obligations or liabilities under or by reason 
of this Agreement or the other Loan Documents.

        SECTION 9.11. Severability. In the event any one or more of the 
                      -------------
provisions contained in this Agreement or in any other Loan Document should be 
held invalid, illegal or unenforceable in any respect, the validity, legality 
and enforceability of the remaining provisions contained herein and therein 
shall not in any way be affected or impaired thereby. The parties shall endeavor
in good-faith negotiations to replace the invalid, illegal or unenforceable 
provisions with valid provisions the economic effect of

                                                                              55

which comes as close as possible to that of the invalid, illegal or 
unenforceable provisions.

        SECTION 9.12. Counterparts. This Agreement may be executed in two or 
                      -------------
more counterparts, each of which shall constitute an original but all of which 
when taken together shall constitute but one contract, and shall become 
effective as provided in Section 9.03.

        SECTION 9.13. Headings. Article and Section headings and the Table of 
                      ---------
Contents used herein are for convenience of reference only, are not part of this
Agreement and are not to affect the construction of, or to be taken into 
consideration in interpreting, this Agreement.

        SECTION 9.14. Jurisdiction; Consent to Service of Process. (a) The 
                      --------------------------------------------
Borrower hereby irrevocably and unconditionally submits, for itself and its 
property, to the nonexclusive jurisdiction of any New York State court or 
Federal court of the United States of America sitting in New York City, and any 
appellate court from any thereof, in any action or proceeding arising out of or 
relating to this Agreement or the other Loan Documents, or for recognition or 
enforcement of any judgment, and each of the parties hereto hereby irrevocably 
and unconditionally agrees that all claims in respect of any such action or 
proceeding may be heard and determined in such New York State or, to the extent 
permitted by law, in such Federal court. Each of the parties hereto agrees that 
a final judgment in any such action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any other manner 
provided by law. Nothing in this Agreement shall affect any right that any 
Lender may otherwise have to bring any action or proceeding relating to this 
Agreement or the other Loan Documents against the Borrower or its properties in 
the courts of any jurisdiction.

        (b)  The Borrower hereby irrevocably and unconditionally waives, to the 
fullest extent it may legally and effectively do so, any objection which it may 
now or hereafter have to the laying of venue of any suit, action or proceeding 
arising out of or relating to this agreement or the other Loan Documents in any 
New York State or Federal court sitting in New York City. Each of the parties 
hereto hereby irrevocably waives, to the fullest extent permitted

by law, the defense of an inconvenient forum to the maintenance of such action 
or proceeding in any such court.

        (c)  Each party to this Agreement irrevocably consents to service of 
process in the manner provided for notices in Section 9.01. Nothing in this 
Agreement will affect the right of any party to this Agreement to serve process 
in any other manner permitted by law.

        IN WITNESS WHEREOF, the Borrower, the Lenders, and the Administrative 
Agent have caused this Agreement to be duly executed by their respective 
authorized officers as of the day and year first above written.

    Company for your breach of this Agreement, the salary provided for in this
    Agreement will be paid to and including the end of the month in which such
    termination of employment occurs. If the Agreement is terminated by the
    Company for any other reason, the Company will pay you on the date of
    termination a sum of money equal to your then current monthly salary times
    the number of months remaining until May 29, 1996, (the second anniversary

    Plan in accordance with the terms of the plan in effect at that time.

    in the preceding paragraph, the payment of such retirement benefits to your
    surviving spouse or you will be made from the regular Pension Plan and a
    Supplemental Pension Plan as appropriate. Payments will be subject to offset

  Primary earnings per common share are computed by dividing net income, after
  deduction of preferred stock dividends, by the weighted average number of
  common shares and common share equivalents outstanding.  Fully diluted
  earnings per common share are computed by dividing net income by the
  weighted average number of common shares and common share equivalents
  outstanding.  Common share equivalents are computed using 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 per common share.  Redeemable preferred stock
  dividends were not significant to any period presented.

  Earnings per common share may not compute due to the level of rounding in
  this exhibit.

(1) Conversion of the preferred stock was based on a November 1992 issuance
    date.
