                     NOTES TO CONDENSED FINANCIAL STATEMENTS

            In the opinion of management, the accompanying unaudited condensed
financial statements of Kirby Corporation and consolidated subsidiaries (the
"Company") contain all adjustments (consisting of only normal recurring
accruals) necessary to present fairly the financial position as of September 30,
1997 and December 31, 1996, and the results of operations for the three months
and nine months ended September 30, 1997 and 1996.

(1)         BASIS FOR PREPARATION OF THE CONDENSED  FINANCIAL STATEMENTS

            The condensed financial statements included herein have been
prepared by the Company, without audit, pursuant to the rules and regulations of
the Securities and Exchange Commission. Although the Company believes that the
disclosures are adequate to make the information presented not misleading,
certain information and footnote disclosures, including significant accounting
policies, normally included in annual financial statements, have been condensed
or omitted pursuant to such rules and regulations. In addition, certain
reclassifications have been made to reflect current presentation of financial
information. It is suggested that these condensed financial statements be read
in conjunction with the Company's latest Annual Report on Form 10-K.

(2)         ADOPTION OF ACCOUNTING STANDARDS

            In February 1997, the Financial Accounting Standards Board ("FASB")
issued Statement of Financial Accounting Standards ("SFAS") No. 128, "Earnings
per Share" ("SFAS No. 128"), which establishes standards for computing and
presenting earnings per share and requires, among other things, dual
presentation of basic and diluted earnings per share on the face of the
statements of earnings. In June 1997, the FASB issued SFAS No. 130, "Reporting
Comprehensive Income" ("SFAS No. 130"), which establishes standards for
reporting and display of comprehensive income and its components in a full set
of financial statements. Comprehensive income includes all changes in a
company's equity, including, among other things, foreign currency transaction
adjustments, notes receivable from employee stock ownership plans and deferred
gains (losses) on hedging activities. Also, in June 1997, the FASB issued SFAS
No. 131, "Disclosures about Segments of an Enterprise and Related Information"
("SFAS No. 131"), which establishes standards for reporting information about
operating segments in annual financial statements and requires that enterprises
report selected information about operating segments in interim reports issued
to shareholders. SFAS No. 128 is effective for financial statements for periods
ending after December 15, 1997 and will be adopted by the Company by December
31, 1997. SFAS No. 130 and SFAS No. 131 are effective for financial statements
for periods beginning after December 15, 1997. The adoption of SFAS No. 128 is
not expected to have a material impact on the Company's calculation of earnings
per share, and the adoption of SFAS No. 130 and SFAS No. 131 is not expected to
have a material impact on the Company's financial condition or results of
operations.

(3)         TAXES ON INCOME

            Earnings  before taxes on income and details of the provision for 
taxes on income for the three months and nine months ended September 30, 1997

 (3)        LONG-TERM DEBT

            On September 19, 1997, the Company agreed to new terms under its
$100,000,000 revolving credit agreement ("Credit Agreement") with Texas Commerce
Bank National Association ("TCB"), as agent bank. Under the new terms, the
Credit Agreement was extended to September 2002, reduced the margin of interest
paid on its borrowings, provided adjusted interest rates based on the Company's
senior credit rating and eliminated certain financial covenants.

            The Company has on file a shelf registration on Form S-3 with the
Securities and Exchange Commission providing for the issue of up to $250,000,000
of medium term notes ("Medium Term Notes") at fixed or floating interest rates
with maturities of nine months or longer. In January 1997, the Company issued
$50,000,000 of the authorized Medium Term Notes at a fixed interest rate of
7.05%, due January 29, 2002. Proceeds from the issuance were used to retire
$34,000,000 of Medium Term Notes due March 10, 1997, with the balance used to
reduce the Company's revolving Credit Agreement. As of September 30, 1997,
$121,000,000 was available under the Medium Term Notes program and $52,000,000
was available for takedown under the Credit Agreement. Both issues are available
to provide financing for future business and equipment acquisitions and working
capital requirements.

 (4)        INSURANCE DISCLOSURE

            The Company's investment in Universal Insurance Company
("Universal"), a property and casualty insurance company operating exclusively
in the Commonwealth of Puerto Rico, is accounted for under the equity method of
accounting. Currently, the Company owns 45% of Universal's voting common stock
and 55% is owned by Eastern America Financial Group, Inc. In March 1997,
Universal redeemed $2,000,000 of Universal's voting common stock, reducing the
Company's voting common stock investment in Universal from 47% to 45%.

            Inland Division revenue for the 1997 third quarter reflected a 1%
increase when compared with the 1996 third quarter. During the 1997 third
quarter, spot market rates reflected a modest increase and term contracts were
generally being renewed at higher rates. Chemical and petrochemical volumes were
positive, however, refined product movements softened in September. The
movements of liquid fertilizer and anhydrous ammonia by the Inland Division are
normally seasonal, coinciding with the spring and fall fertilizer season. The
1997 fall fertilizer season, normally starting in late August or early
September, did not strengthen until early October, resulting in an estimated
$1,000,000 reduction in 1997 third quarter and nine months revenue.

            The Inland Division's revenue was derived from long-term contracts,
short-term contracts and spot movements of products for customers in the
chemical, petrochemical, agricultural chemical and refined products markets. As
of September 30, 1997 and 1996, approximately 80% of inland movements were under
term contracts and 20% were spot movements of products.

            The Company's harbor tug operation for the 1997 third quarter and
1997 first nine months were reported within the Offshore Division. For
comparative purposes, the 1996 third quarter and 1996 first nine months results
for the harbor tug operation have been reclassified from the Inland Division to
the Offshore Division. Revenue for the harbor tug operation for the 1997 third
quarter and 1997 first nine months were $2,600,000 and $7,300,000, respectively,
compared with revenue for the 1996 third quarter and 1996 first nine months of
$2,300,000 and $6,200,000, respectively.

                     Management's Discussion and Analysis of
                  Financial Condition and Results of Operations


            Revenue for the Inland Division for the 1997 first nine months
increased 2% compared with the first nine months of 1996. Since early 1997, the
Inland Division has experienced a modest hike in utilization and spot market
rates, and contracts have generally been renewed at higher rates. Within the
past year, the Company has removed from service 25 single skin barges and have
placed into service six new double skin barges, for a net 3% reduction in inland
fleet capacity. Older vessels have historically been removed from service when
it is not prudent to continue to maintain or overhaul the vessel. In addition,
the 1997 first nine months revenue was negatively impacted by the flooding on
the Mississippi River System during the months of February through April. During
the majority of the 1997 first quarter, the upper Mississippi River and Ohio
River experienced high water and flooding conditions, with river closures in
selected areas and mandated regulatory operating restrictions. During the month
of March, and extending into April, the lower Mississippi River, the Company's
principal area of operation, experienced high water not seen in such severity
since 1983. The loss of revenue, estimated at approximately $3,450,000 for the
months of February through April, was the result of delays, diversions and
limitations on night passages, horsepower requirements and size of tows. The
effects of the flooding throughout the Mississippi River System reduced the
Company's revenues and increased its expenses, resulting in a reduction in net
earnings by an estimated $.10 per share for the 1997 first nine months.

            The Offshore Division experienced a 7% reduction in revenue during
the 1997 third quarter compared with the 1996 third quarter, and a 2% reduction
for the 1997 first nine months compared with the first nine months of 1996.
Since early April, the Company's Jones Act product tanker fleet have experienced
a soft demand for their services, resulting in lower rates and the lay-up of
spot market tankers for extended periods of time. The Jones Act tanker market is
currently suffering from an overcapacity of vessels. Such additional capacity
competing for spot market movements, expanded production by Northeast and West
Coast refineries, and the movement of lower volumes of gasoline blending
components, have all contributed to the continued soft demand for offshore
refined product movements. In addition, two tankers were out of service for part
of the 1997 third quarter for scheduled overhauls.

            The Company is currently reviewing alternative strategies concerning
its Jones Act product tanker fleet. Such strategies range from a direct sale of
the fleet, to alternative marketing arrangements designed to better insulate the
Company from fluctuations in the market, to continuing to operate the fleet, but
at reduced levels.

            In October, the last of the Company's three preference food-aid
freighters was sold following a food-aid voyage to East Africa. In May and
September 1997, the first and second freighters were sold following food-aid
trips to North Korea. Each of the freighters were sold for scrap. Lack of
available movements and corresponding low rates have negatively impacted this
segment of the Offshore Division for several years.

            The Diesel Repair Division's revenue for the 1997 third quarter
decreased 2% compared with the 1996 third quarter, while the 1997 first nine
months revenue increased 23% compared with the first nine months of 1996. During
the 1997 third quarter, as well as the 1997 first and second quarters, the
Division's Midwest market was negatively impacted by deferred overhauls by
inland towing customers due to the spring flooding and by dry cargo customers
due to slow grain exports. The Division's Gulf Coast and East Coast markets have
remained positive. In addition to the impact on revenue noted above, the 23%
increase for the 1997 first nine months over the corresponding period of the
prior year was primarily due to the inclusion of MKW Power Systems, Inc.
("MKW"), whose operating assets were acquired on July 31, 1996.

            Costs of sales and operating expenses for the 1997 third quarter
remained constant compared with the third quarter of 1996, while costs of sales
and operating expenses for the 1997 first nine months increased 7% compared with
the first nine months of 1996. The 7% increase was largely due to the additional
expenses associated with the Diesel Repair Division's acquisition of MKW. In
addition, the Inland Division's operating expenses increased during February
through April 1997, reflecting the high costs and equipment utilization
associated with the flooding. During 1997, the Inland Division's labor costs
have also increased, requiring the use of external tankerman services. The
Company competes with the same labor pool as companies participating in the
increased drilling activities in the Gulf of Mexico.

            Selling, general and administrative expenses increased 1% for the
1997 third quarter and 6% for the first nine months when compared with the
corresponding periods of 1996. The 6% increase was primarily due to the
additional expenses associated with the Diesel Repair Division's acquisition of
MKW, which was partially offset by lower corporate general and administrative
expenses, the result of the 1996 reorganization, which reduced administrative
costs.

                  Financial Condition and Results of Operations

            Taxes, other than on income for the 1997 third quarter increased 19%
and for the 1997 first nine months increased 7% when compared with the
corresponding 1996 periods. The increases for both periods primarily reflect
higher property taxes on new inland tank barges placed into service within the
past two years.

            The Company currently has a 45% voting common stock investment in
Universal. The amount recorded by the Company as equity in earnings for the
Company's investment in Universal is influenced to the extent that anticipated
future redemptions by Universal of its common stock exceeds the Company's
investment in Universal's stock. The Company also has a 100% investment in
Universal's nonvoting preferred stock. Because the preferred stock controls a
separate portfolio of U.S. Treasury Securities, the Company accounts for this
preferred stock under SFAS 115. Therefore, the interest earned, as well as the
realized gains from the sale of U.S. Treasury Securities collateralizing the
preferred stock, were included as part of equity in earnings of the insurance
affiliate. For the 1997 and 1996 third quarters and first nine months, the
Company recorded $272,000 and $245,000, and $784,000 and $723,000, respectively,
of interest earned from its investment in U.S. Treasury Securities, and
recognized during the 1996 first quarter $582,000 of realized gains from the
sale of such U.S. Treasury Securities, which were included in equity in earnings
of insurance affiliate.

            The Company recognized in the 1997 second quarter as equity in
earnings of insurance affiliate, $2,500,000 of cash received from Universal as
the result of a resolution of a previously reserved Universal contingency for
outstanding litigation. The litigation was fully reserved on Universal's
financial records and was set aside as part of the merger in 1992 of Universal
with Eastern America.

            Equity in earnings of marine affiliates, representing the Company's
investment in two offshore marine partnerships, reflected a 32% decrease for the
1997 third quarter compared with the 1996 third quarter, and a 29% decrease for
the first nine months of 1997 compared with the first nine months of 1996.
Results for the 1997 third quarter and first nine months were negatively
impacted by additional scheduled maintenance on the partnerships' vessels and by
lower coal volume requirements than the 1996 comparable periods.

            Interest expense reflected a 4% decrease for the 1997 third quarter
compared with the third quarter of 1996 and a 2% increase for the 1997 first
nine months compared with the first nine months of 1996. Long-term debt was
increased to finance the purchase of treasury stock acquired primarily in the
1997 first quarter and to finance the tank barge construction project completed
during the 1997 first quarter. Both items are discussed in more detail below.
During the 1997 second quarter and third quarter, excess cash flows from
operating activities were used to pay-down the long-term debt, resulting in the
4% decrease in interest expense for the 1997 third quarter.

            As of September 30, 1997, working capital increased to $51,050,000,
a 27% improvement when compared to $40,194,000 at December 31, 1996. Cash
increased to $3,105,000 at September 30, 1997 from $1,544,000 at December 31,
1996, primarily due to positive cash flow from operating activities.
Available-for-sale securities increased to $21,006,000 at September 30, 1997
from $18,199,000 at December 31, 1996. The increase in securities was the result
of positive cash flow from the Company's captive insurance operation. Inventory
levels increased to $17,398,000 from $16,361,000 during the first nine months of
1997. The increase resulted from higher inventory levels carried at the
Company's Gulf Coast diesel repair facilities to service the strong offshore
drilling market. Prepaid expenses increased to $15,803,000 from $13,315,000 at
December

31, 1996, primarily due to the number of offshore vessels out of service during
1997 for scheduled maintenance. Such maintenance costs are charged to operating
expense over the period between such scheduled maintenance.

            Accounts payable at September 30, 1997 totaled $20,477,000, down
from $30,518,000 at December 31, 1996. The depressed Jones Act tanker market,
which has resulted in the lay-up of offshore tankers, and the decreased food-aid
freighter activity contributed significantly to the decline in accounts
payables. Accrued liabilities at September 30, 1997 totaled $54,430,000, up from
$44,511,000 at December 31, 1996. The majority of the increase was higher
accruals for scheduled repair and maintenance for inland vessels, which are
charged to operating expense based on estimated annual expenditures and higher
accrued interest.

            The 3% decrease in property and equipment reflected the depreciation
for the 1997 first nine months of approximately $24,400,000, partially offset by
approximately $18,500,000 of capital additions. Other assets decreased 19%
primarily for the amortization of excess costs of consolidated subsidiaries and
other intangibles of approximately $1,700,000.

            Long-term debt, more fully described below, decreased 7%, reflecting
significant pay-downs on debt from the operating cash flows generated during the
1997 first nine months. Offsetting the pay-downs were additional debt incurred
with the repurchase of the Company's common stock and the recently completed
barge construction project, both of which are more fully described below.
Stockholders' equity increased 5% during the 1997 first nine months, reflecting
net earnings of $18,793,000, which was offset by the purchase of treasury stock
of $10,887,000 during the year, and a minor increase in the unrealized value of
available-for-sale securities.

LONG-TERM DEBT

            On September 19, 1997, the Company agreed to new terms under its
$100,000,000 revolving credit agreement ("Credit Agreement") with Texas Commerce
Bank National Association ("TCB"), as agent bank. Under the new terms, the
Credit Agreement was extended to September 2002, reduced the margin of interest
paid on its borrowings, provided adjusted interest rates based on the Company's
senior credit rating and eliminated certain financial covenants. Proceeds from
the Credit Agreement may be used for general corporate purposes, including the
purchase of existing or new equipment or for possible business acquisitions.

            In January 1997, the Company issued $50,000,000 of Medium Term Notes
at a fixed interest rate of 7.05% due January 29, 2002. Proceeds from the
issuance were used to retire the $34,000,000 of Medium Term Notes due March 10,
1997, with the balance used to reduce the Company's $100,000,000 revolving
Credit Agreement. As of September 30, 1997, $95,000,000 was outstanding under
the Medium Term Notes program and $48,000,000 was outstanding under the Credit
Agreement.

CAPITAL EXPENDITURES

            The Company continued to enhance its existing operations through the
construction of new equipment. During the 1997 first quarter the final two new
inland tank barges were placed in service, completing the order of 24
double-skin 29,000 barrel capacity barges. The construction project cost
approximately $1,500,000 per barge. Funds for the construction project were
available through the Company's Credit Agreement and cash provided by operating
activities.

TREASURY STOCK PURCHASES

            During the 1997 first quarter, the Company purchased 564,450 shares
of its own common stock at a total purchase price of $10,608,000, for an average
price of $18.80 per share. In the 1997 second quarter, the Company purchased
16,200 shares of its common stock at a total purchase price of $279,000, for an
average price of $17.20 per share. As of October 30, 1997, the Company had
1,859,000 shares available under the 6,250,000 total repurchase authorization.
The treasury stock purchases were financed by borrowings under the Company's
Credit Agreement. The Company is authorized to purchase its common stock on the
New York Stock Exchange and in privately negotiated transactions. When
purchasing its common stock, the Company is subject to price, trading volume and
other market considerations. Shares purchased may be used for reissuances upon
the exercise of stock options, in future acquisitions for stock or for other
appropriate corporate purposes.

LIQUIDITY

            During the last three years, inflation has had a relatively minor
effect on the financial results of the Company. The marine transportation
segment has long-term contracts which generally contain cost escalation clauses
whereby certain costs, including fuel, can be passed through to its customers,
while the transportation assets acquired and accounted for using the purchase
method of accounting were adjusted to a fair market value and, therefore, the
cumulative long-term effect on inflation was reduced. The repair portion of the
diesel repair segment is based on prevailing current market rates or on
negotiated service contracts with its customers. The Company does not presently
use financial derivatives, but uses a mix of floating and fixed rate debt. The
Company has no foreign exchange risks.

            The Company has no present plan to pay dividends on its common
stock.

ACCOUNTING STANDARDS

            In February 1997, the FASB issued SFAS No. 128, "Earnings per Share"
which establishes standards for computing and presenting earnings per share and
requires, among other things, dual presentation of basic and diluted earnings
per share on the face of the statements of earnings. In June 1997, the FASB
issued SFAS No. 130, "Reporting Comprehensive Income," which establishes
standards for reporting and display of comprehensive income and its components
in a full set of financial statements. Comprehensive income includes all changes
in a company's equity, including, among other things, foreign currency
transaction adjustments, notes receivable from employee stock ownership plans
and deferred gains (losses) on hedging activities. Also in June 1997, the FASB
issued SFAS No. 131, "Disclosures about Segments of an Enterprise and Related
Information," which establishes standards for reporting information about
operating segments in annual financial statements and requires that enterprises
report selected information about operating segments in interim reports issued
to shareholders. SFAS No. 128 is effective for financial statements for periods
ending after December 15, 1997 and will be adopted by the Company by December
31, 1997. SFAS No. 130 and SFAS No. 131 are effective for financial statements
for periods beginning after December 15, 1997. The adoption of SFAS No. 128 is
not expected to have a material impact on the Company's calculation of earnings
per share, and the adoption of SFAS No. 130 and SFAS No. 131 is not expected to
have a material impact on the Company's financial condition or results of
operations.
