NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

JUNE 30, 1998
________________________________________________________________________________

(1)  BASIS OF PRESENTATION

     The TransMontaigne Inc. ("TransMontaigne"), formerly TransMontaigne Oil
     Company, consolidated balance sheets at June 30, 1998 and April 30, 1998,
     the consolidated statements of operations for the two months ended June 30,
     1998 and three months ended July 31, 1997, the consolidated statements of
     stockholders' equity for the two months ended June 30, 1998 and year ended
     April 30, 1998 and the consolidated statements of cash flows for the two
     months ended June 30, 1998 and three months ended July 31, 1997 are
     unaudited and reflect all adjustments (consisting only of normal recurring
     adjustments) which are, in the opinion of management, necessary for a fair
     presentation of the financial position and operating results for the
     interim periods presented. These consolidated financial statements should
     be read in conjunction with the consolidated financial statements and
     related notes, together with management's discussion and analysis of
     financial condition and results of operations, contained in
     TransMontaigne's Annual Report on Form 10-K for the fiscal year ended April
     30, 1998.

     Management makes various estimates and assumptions in determining the
     reported amounts of assets, liabilities, revenues and expenses for each
     period presented. Changes in these estimates and assumptions will occur as
     a result of the passage of time and the occurrence of future events, and
     actual results will differ from the estimates.

     On August 14, 1998, the Board of Directors of TransMontaigne voted to
     change TransMontaigne's fiscal year end from April 30 to June 30, to be
     effective June 30, 1998. Accordingly, TransMontaigne is filing this
     transition report on Form 10-Q for the two months ended June 30, 1998. This
     new fiscal year end will allow TransMontaigne to conform to the predominant
     calendar quarterly reporting periods used in its industry.

(2)  ACQUISITIONS

     On November 25, 1997, TransMontaigne, through a wholly-owned subsidiary,
     TransMontaigne Terminaling Inc., acquired the common stock of 17
     corporations, known as the "ITAPCO Terminal Corporations", and certain
     related property and property interests. The acquisition included 17
     storage and distribution terminals located in 8 states having total tankage
     capacity in excess of 3.3 million barrels, handling primarily refined
     petroleum products, chemicals and other bulk liquids together with the
     related operations of the terminals and certain other assets.

     The ITAPCO Terminal Corporations purchase price was $32,000,000
     ($31,458,000 cash plus assumption of outstanding bank debt of approximately
     $542,000) and was funded by an advance of $22,000,000 from the
     TransMontaigne bank credit facility with the balance from TransMontaigne
     cash reserves. The 17 ITAPCO Terminal Corporations were merged into a
     wholly-owned subsidiary of TransMontaigne effective December 1, 1997. The
     cost of the ITAPCO Terminal Corporations has been allocated to the terminal
     facilities acquired and to the other related assets acquired and
     liabilities assumed based on their estimated fair market value as
     determined by TransMontaigne. The transaction was accounted for as a
     purchase.

     On December 20, 1996, TransMontaigne, through a wholly-owned subsidiary,
     Bear Paw Energy Inc., acquired for approximately $71,000,000 cash the
     Grasslands natural gas gathering, treating, processing and fractionating
     system located in western North Dakota and northeastern Montana (the
     "Grasslands Facilities"). The cost of the Grasslands Facilities has been
     allocated to the assets acquired based on their estimated fair market value
     as determined by TransMontaigne. The transaction was accounted for as a
     purchase.

     The following summarized unaudited pro forma results of operations assumes
     that the acquisition of the ITAPCO Terminal Corporations occurred as of May
     1, 1997 and combines the historical results of operations of TransMontaigne
     for the three months ended July 31, 1997 with the historical results of
     operations of the ITAPCO Terminal Corporations for the three months ended
     July 31, 1997.

     The unaudited pro forma results of operations are not necessarily
     indicative of the results of operations which would actually have occurred
     if the ITAPCO Terminal Corporations had been acquired as of May 1, 1997 or
     which will be attained in the future.

</TABLE>

(3)  Public Offering

     In February 1997, TransMontaigne closed a public offering of 4,357,000
     shares of its common stock of which 4,035,000 shares were issued and sold
     by TransMontaigne and 322,000 shares were sold by certain selling
     stockholders. The net proceeds to TransMontaigne, based on the public
     offering price of $14.25 per share, were approximately $53,506,000, after
     deducting underwriting discounts and commissions and offering costs, of
     which $45,000,000 was used to repay a portion of the debt incurred under
     its bank credit facility. In March 1997 the underwriters' overallotment to
     purchase an additional 557,543 shares and the Merrill Lynch Growth Fund
     antidilution right to purchase an additional 98,390 shares were both
     exercised and TransMontaigne received additional net proceeds of
     $8,809,000.

(4)  INVENTORY MANAGEMENT

     TransMontaigne manages the risk associated with fluctuations in the price
     of refined petroleum products inventory and purchase and sales commitments,
     and may selectively enter into futures contracts which are designated as
     hedges of the products purchased or sold. Hedging gains and

                                       10
<PAGE>
 
     losses are recognized and recorded in inventory when the related inventory
     is sold. At June 30, 1998, TransMontaigne had no open futures contracts
     designated as hedges.

     In connection with its trading activities, TransMontaigne recognizes gains
     and losses when incurred. Net trading losses on futures contracts of
     approximately $1,235,000 were recognized during the two months ended June
     30, 1998 and gains of approximately $591,000 were recognized during the
     quarter ended July 31, 1997. TransMontaigne had outstanding contracts to
     sell 14,856,000 barrels of product and outstanding contracts to purchase
     14,856,000 barrels of product at June 30, 1998 and outstanding contracts to
     sell 2,200,000 barrels of product and outstanding contracts to purchase
     2,200,000 barrels of product at July 31, 1997. Unrealized gains relating to
     such outstanding contracts of approximately $4,926,000 at June 30, 1998 and
     approximately $515,000 at July 31, 1997 have been included in product sales
     and product costs and direct operating expenses in the accompanying
     consolidated statements of operations.

     TransMontaigne's refined petroleum products inventory consists primarily of
     gasoline and distillates.  A portion of TransMontaigne's refined petroleum
     products inventory represents line fill and tank bottoms; is required for
     operating balances in the conduct of TransMontaigne's daily supply and
     distribution activities; and is maintained both in tanks and pipelines
     owned by TransMontaigne and pipelines owned by third parties. Natural gas
     liquids and residue natural gas inventory are not significant. Inventories
     of refined petroleum products are stated at the lower of last-in, first-out
     (LIFO) cost or market.

     As of June 30, 1998 TransMontaigne recorded an additional adjustment of
     approximately $1,880,000 to reduce inventories to the lower of cost (LIFO)
     or market which increased the net loss (after providing for the income tax
     benefit) for the two months ended June 30, 1998 by approximately
     $1,220,000.

(5)  INCOME TAXES
 
     TransMontaigne utilizes the asset and liability method of accounting for
     income taxes, as prescribed by Statement of Financial Accounting Standards
     No. 109.  Under this method, 

                                       11
<PAGE>
 
     deferred tax assets and liabilities are recognized for the future tax
     consequences attributable to differences between the financial statement
     carrying amounts of existing assets and liabilities and their respective
     tax bases. Deferred tax assets and liabilities are measured using enacted
     tax rates expected to apply in the years in which these temporary
     differences are expected to be recovered or settled. Changes in tax rates
     are recognized in income in the period that includes the enactment date.

(6)  BANK CREDIT FACILITY

     TransMontaigne's bank credit facility at June 30, 1998 is a $175,000,000
     working capital revolving credit facility with a money center bank due
     December 31, 2002. Borrowings under the bank credit facility generally bear
     interest at an annual rate equal to the lender's announced Base Rate,
     subject to a Eurodollar pricing option at TransMontaigne's election. The
     interest rate at June 30, 1998 was 6.375%.

     As of June 30, 1998, TransMontaigne had advances of $50,000,000 outstanding
     under the bank credit facility. In addition, $2,600,000 of the facility was
     used to support a standby letter of credit to a bank to assist Lion Oil
     Company, a corporation in which TransMontaigne owns a net 18.04% interest,
     in obtaining financing.

(7)  Master Shelf Agreement

     In April 1997, TransMontaigne entered into a Master Shelf Agreement with an
     institutional lender which provides that the lender will agree to quote,
     from time to time, an interest rate at which the lender would be willing to
     purchase, on an uncommitted basis, up to $100,000,000 of TransMontaigne's
     senior promissory notes which will mature in no more than 12 years, with an
     average life not in excess of 10 years.

     TransMontaigne sold to the lender, under the Master Shelf Agreement,
     $50,000,000 of 7.85% Senior Notes due April 17, 2003 in April 1997 and
     $25,000,000 of 7.22% Senior Notes due October 17, 2004 in December 1997,
     all of which was outstanding at June 30, 1998.

(8)  SENIOR SUBORDINATED DEBENTURES

     In March 1991, TransMontaigne issued $4,000,000 of 12 3/4% senior
     subordinated debentures which are guaranteed by certain subsidiaries; are
     due December 15, 2000; are subject to a required redemption of $2,000,000
     on December 15, 1999 and December 15, 2000, respectively; and may be
     prepaid prior to maturity at a premium. In connection with the issuance of
     these debentures, TransMontaigne issued warrants to purchase 248,686 shares
     of common stock at $3.60 per share, through December 15, 2000.

(9)  Restricted Stock

     TransMontaigne has a restricted stock plan that provides for awards of
     common stock to certain key employees, subject to forfeiture if employment
     terminates prior to the vesting dates. The market value of shares awarded
     under the plan is recorded in stockholders' equity as unearned
     compensation. During the fiscal year ended April 30, 1998, the
     TransMontaigne Board of Directors approved the issuance of 56,000 shares to
     certain key employees. As of June 30, 1998, 4,400 shares had vested.
     Unearned compensation is amortized over the four year vesting period of the
     awards. Amortization of unearned compensation of $62,183 is included in
     general and administrative expense for the two months ended June 30, 1998.
     Accumulated amortization was $320,652 at June 30, 1998.

(10) Business Segments

     TransMontaigne's operating business segments include the logistical
     petroleum services related to pipelining, terminaling and storing,
     marketing and supply and distribution of refined petroleum products;
     natural gas services related to gathering, processing, treating and
     marketing of natural gas liquids and residue gas; and corporate services
     related to all of TransMontaigne's activities and assets which are not
     specifically identified with logistical petroleum and natural gas services,
     which include cash and cash equivalents, investments and other assets. In
     November 1997, TransMontaigne acquired the ITAPCO Terminal Corporations,
     the refined

                                       13
<PAGE>
 
     petroleum products, chemicals and other bulk liquids operations of which
     are included in the logistical petroleum services business segment.

(11) EARNINGS PER SHARE

     Earnings per share ("EPS") has been calculated based on the weighted
     average number of common shares outstanding for the period in accordance
     with the Statement of Financial Accounting Standards No. 128 issued in
     February 1997. The following tables reconcile the computation of basic EPS
     and diluted EPS for the two months ended June 30, 1998 and three months
     ended July 31, 1997.

            computation of diluted EPS because the options' exercise price was
            greater than the average market price of the common shares during
            the two months ended June 30, 1998 and the effect was anti-dilutive.

(12) NEW ACCOUNTING STANDARD

     Effective May 1, 1998, TransMontaigne adopted the Statement of Financial
     Accounting Standards No. 130, "Reporting Comprehensive Income" ("SFAS
     130"), which was issued in June 1997, by the Financial Accounting Standards
     Board. SFAS 130 established new standards which require that changes in
     comprehensive income be shown in a financial statement that is displayed
     with the same prominence as other financial statements. Comprehensive
     income is net

                                       15
<PAGE>
 
     earnings (loss), plus certain other items that are recorded directly to
     stockholders' equity. The adoption of this statement had no impact on the
     financial statements of TransMontaigne.

(13) SUBSEQUENT EVENTS

     On July 29, 1998, TransMontaigne acquired Statia Terminals Southwest, Inc.
     for $6,500,000 cash. The acquisition included terminaling, storage and
     loading facilities for petroleum products, chemicals and other bulk liquids
     at the Port of Brownsville, Texas with over 1.6 million barrels of tank
     storage, 12 truck rack loading bays, connections to barge and tanker
     loading facilities and the exclusive use of 5 railroad spur lines with a
     total of 32 railroad car loading spots. 

     On September 14, 1998, TransMontaigne announced a definitive agreement to
     acquire Louis Dreyfus Energy Corp. for approximately $161,000,000, plus
     working capital. The consideration will consist of approximately
     $100,000,000 cash and 4.5 million shares of TransMontaigne common stock.
     The transaction is expected to close prior to December 31, 1998, subject to
     the completion of due diligence by TransMontaigne and the receipt of
     regulatory approvals.

     On September 18, 1998, TransMontaigne acquired for $29,219,000 cash the
     15.38% common stock interest in West Shore Pipe Line Company owned by
     Atlantic Richfield Company.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF
         FINANCIAL CONDITION AND RESULTS OF OPERATIONS

GENERAL

     TransMontaigne provides a broad range of integrated transportation,
terminaling, supply, distribution, gathering, processing and marketing services
to producers, refiners, distributors, marketers and end-users of petroleum
products, chemicals, other bulk liquids, natural gas and crude oil in the
downstream sector of the petroleum and chemical industry. TransMontaigne is a
holding company which conducts its operations through subsidiaries primarily in
the Mid-Continent and Rocky Mountain regions of the United States.
TransMontaigne does not explore for, or produce, crude oil or natural gas; does
not own crude oil or natural gas reserves; and does not own chemicals or other
bulk liquids inventory.

     TransMontaigne owns and operates refined petroleum products, chemicals,
other bulk liquids, crude oil and natural gas assets.  TransMontaigne's refined
petroleum products, chemicals, other bulk liquids and crude oil assets consist
primarily of approximately 790 miles of pipeline and 31 terminal, storage and
delivery facilities located in 10 states with a combined tank storage capacity
of approximately 8,500,000 barrels.  TransMontaigne's natural gas gathering and
processing assets consist of 5 gathering and processing systems in 3 states with
combined throughput capacity of approximately 94 million cubic feet per day and
over 2,800 miles of pipelines.  TransMontaigne also extensively utilizes refined
petroleum products common carrier pipelines and terminals owned by third parties
in order to increase product volumes shipped, marketed and sold to and exchanged
with customers in other locations.  Management believes that the use of all
these facilities should allow TransMontaigne to significantly expand its
geographic service area and the integrated logistical services it provides.

     The principal predecessor of TransMontaigne was formed in 1977. In April
1995, present management and certain institutional stockholders of
TransMontaigne acquired control of the predecessor through a merger in which the
name was changed to TransMontaigne Oil Company. In June 1996, TransMontaigne and
a publicly held corporation merged, with the stockholders of

                                       17
<PAGE>
 
TransMontaigne receiving approximately 93% of the stock of the merged
corporation. In August 1998, upon receiving shareholders' approval, the name
TransMontaigne Oil Company was changed to TransMontaigne Inc.

     Since TransMontaigne's present management assumed control in April 1995,
TransMontaigne has raised approximately $117,000,000 in equity capital
($30,000,000 private placement in May 1995; $25,000,000 private placement in
March 1996; and $62,000,000 public offering in February 1997); established an
initial $130,000,000 working capital and acquisition revolving bank credit
facility in December 1996 which converted to an $85,000,000 bank credit facility
in February 1997, and which in April 1998 was increased to a $175,000,000 bank
credit facility due December 31, 2002; and issued $50,000,000 of 7.85% Senior
Notes due April 17, 2003 in April 1997 and $25,000,000 of 7.22% Senior Notes due
October 17, 2004 in December 1997 to an institutional lender under a
$100,000,000 Master Shelf Agreement.

     In December 1996, TransMontaigne acquired the Grasslands natural gas
gathering, processing, treating and fractionation system (the "Grasslands
Facilities") for approximately $71,000,000 in cash and through June 30, 1998 has
additionally invested approximately $22,500,000 in improvements and expansion of
the Grasslands Facilities and other assets in its natural gas services business
segment. The Grasslands Facilities are strategically located between
TransMontaigne's Marmarth facility in southwestern North Dakota, its Baker
facility in eastern Montana and its Lignite facility in northern North Dakota.
TransMontaigne has natural gas gathering facilities covering the eastern
corridor of Montana and the western quarter of North Dakota, from the Canadian
border to the South Dakota border, which should significantly enhance
TransMontaigne's ability to provide a complete service package to North Dakota
and Montana producers as well as to end-users of natural gas liquids ("NGL") and
natural gas.  The Grasslands Facilities contributed approximately 86% and 92% of
the total net operating margins of TransMontaigne's natural gas gathering and
processing operations during the two months ended June 30, 1998 and the three
months ended July 31, 1997, respectively.

     In November 1997, TransMontaigne acquired the common stock of 17
corporations, known as the "ITAPCO Terminal Corporations", and certain related
property and property interests.  The acquisition included 17 bulk liquid
storage and distribution terminals located in 8 states having total 

                                       18
<PAGE>
 
tankage capacity in excess of 3.3 million barrels, handling primarily refined
petroleum products, chemicals and other bulk liquids together with the related
operations of the terminals; and certain other assets. The ITAPCO Terminal
Corporations purchase price was $32,000,000 ($31,458,000 cash, plus assumption
of outstanding bank debt of approximately $542,000) and was funded by an advance
of $22,000,000 from the TransMontaigne bank credit facility with the balance
from TransMontaigne cash reserves. The ITAPCO Terminal Corporations contributed
approximately 53% of the total net operating margins of the TransMontaigne
terminal operations during the two months ended June 30, 1998.

     Subsequent to the acquisition of the ITAPCO Terminal Corporations,
TransMontaigne acquired for an aggregate cash sum of $4,686,000 the remaining
50% interest in a 153,000 barrel terminal located in Owensboro, Kentucky, which
it did not previously own; a 259,000 barrel terminal located in Greenville,
Mississippi; and the remaining 50% interest in a partnership which owned and
operated a natural gas gathering and processing facility located in Lignite,
North Dakota, which it did not previously own.

     On July 29, 1998, TransMontaigne acquired Statia Terminals Southwest, Inc.
for $6,500,000 cash. The acquisition included terminaling, storage and loading
facilities for petroleum products, chemicals and other bulk liquids at the Port
of Brownsville, Texas with over 1.6 million barrels of tank storage, 12 truck
rack loading bays, connections to barge and tanker loading facilities and the
exclusive use of 5 railroad spur lines with a total of 32 railroad car loading
spots.

     On September 18, 1998, TransMontaigne acquired for $29,219,000 cash the
15.38% common stock interest in West Shore Pipe Line Company ("West Shore")
owned by Atlantic Richfield Company.  West Shore owns a 600-mile common carrier
petroleum products pipeline system which operates in the Chicago, Illinois area
north along the western edge of Lake Michigan into the Green Bay and Madison,
Wisconsin area.  The pipeline serves approximately 55 locations, including 4
refineries, the Chicago-O'Hare and Milwaukee airports, and 49 refined petroleum
products terminals in the Chicago, Illinois area and the upper Mid-West region
of the United States.  TransMontaigne will be the second largest owner of West
Shore, whose ownership also includes Citgo, Marathon, Equilon, Texaco, Amoco,
Midwest (Union Oil), Mobil and Exxon.

                                       19

     On September 14, 1998, TransMontaigne announced a definitive agreement to
acquire Louis Dreyfus Energy Corp. ("LDEC") for approximately $161,000,000, plus
working capital. The consideration will consist of approximately $100,000,000
cash and 4.5 million shares of TransMontaigne common stock. The transaction is
expected to close prior to December 31, 1998, subject to the completion of due
diligence by TransMontaigne and the receipt of regulatory approvals. LDEC
operates 24 refined petroleum products terminal and storage facilities of which
7 are wholly-owned and 17 of which are owned jointly with BP Oil Company. These
facilities are located in 9 states in the southern and eastern regions of the
United States; are supplied primarily by the Colonial and/or Plantation pipeline
systems; include over 350 service supply/exchange points nationwide; and
annually handle in excess of 85 million barrels of refined petroleum products.

     TransMontaigne intends to continue to make strategic additions to and
expansions of its existing facilities as necessary in order to maintain quality
service levels, increase operating efficiencies, achieve incremental net

(1)  Pipeline volumes are expressed in thousands of barrels (42 gallons per
     barrel).  Terminal and storage and products supply and distribution volumes
     are expressed in thousands of gallons.

(2)  Revenues, net operating margins (losses), and net earnings (loss) are
     expressed in thousands of dollars.  Net operating margin (loss) represents
     (a)  revenues less direct operating expenses for pipeline and terminal and
     storage operations; (b) revenues less cost of refined petroleum products
     purchased for products supply and distribution operations, and (c) revenues
     less cost of natural gas gathered, processed and sold and direct operating
     expenses for natural gas services operations.

(3)  Natural gas inlet volumes are expressed in million cubic feet; NGL
     production is expressed in thousands of gallons; and residue natural gas
     production is expressed in million British Thermal Units.

     Prior to the acquisition of the ITAPCO Terminal Corporations facilities in
November 1997 and the Grasslands Facilities in December 1996, TransMontaigne's
revenues were derived from the logistical petroleum services business segment
consisting primarily of transporting refined petroleum products (and to a lesser
extent crude oil) in pipelines; the storage and terminaling of refined petroleum
products; and the supply, distribution and marketing of refined petroleum
products.  The storage and terminaling of chemicals and other bulk liquids
became a component of the logistical petroleum business segment following the
ITAPCO Terminal Corporations acquisition.  Natural gas services became a
separate business segment with the acquisition of the Grasslands Facilities.

     Pipeline revenues are based on the volume of refined petroleum products or
crude oil transported and the distance from the origin point to the delivery
point. TransMontaigne's interstate pipeline systems transport refined petroleum
products and their tariffs are regulated by the Federal Energy Regulatory
Commission (the "FERC"). TransMontaigne's intrastate pipeline transports crude
oil and its tariffs are not regulated by the FERC, but are regulated by the
Texas Railroad Commission.

     Terminal revenues are based on the volume of refined petroleum products
handled, generally at a standard per gallon rate.  Terminal fees are not
regulated.  Storage fees are generally based on a per barrel rate or tankage
capacity committed and will vary with the duration of the arrangement, the

                                       23
<PAGE>
 
product stored and special handling requirements, particularly when certain
types of chemicals and other bulk liquids are involved.  Storage fees are not
regulated.

     Direct operating expenses of pipeline and terminal and storage operations
include wages and employee benefits, utilities, communications, maintenance and
repairs, property taxes, rent, insurance, vehicle expenses, environmental
compliance costs, materials and supplies.

     Products supply and distribution revenues are based on the volume of bulk
sales of refined petroleum products and the wholesale distribution of refined
petroleum products from terminals. Bulk purchase and sale transactions in
quantities of 25,000 barrels to 50,000 barrels are common and are generally made
at small margins. Wholesale distribution of refined petroleum products is
conducted from 8 proprietary and 71 nonproprietary terminal truck loading rack
locations primarily by truckload sales of 8,000 gallons.

     Direct operating expenses of products supply and distribution operations
are primarily the cost of products sold and also include transportation,
terminaling and sales commission expenses.

     Natural gas gathering and processing revenues are based on the inlet volume
of natural gas purchased from producers under both percentage of proceeds and
fee based arrangements.  Natural gas is gathered and processed into NGL
products, principally propane, butane and natural gasoline.  These products are
transported by truck or pipeline to storage facilities from which they are
further transported and marketed by TransMontaigne to wholesalers and end-users.
Residue natural gas is delivered to and marketed through connections with third-
party interstate natural gas pipelines.

     Direct operating expenses of natural gas gathering and processing
operations include wages and employee benefits, utilities, maintenance and
repairs, property taxes, rent, insurance, vehicle expenses, environmental
compliance costs, material and supplies.

TWO MONTHS ENDED JUNE 30, 1998 COMPARED TO
     THREE MONTHS ENDED JULY 31, 1997

     On August 14, 1998, TransMontaigne elected to change the date of its fiscal
year end to June 30.  The management discussion that follows compares the two
months ended June 30, 1998 and the three months ended July 31, 1997.
TransMontaigne did not recast historical financial information to present the
two months ended June 30, 1997 because the financial reporting systems in place
at that time included certain procedures which were completed only on a
quarterly basis.  Consequently, it is impractical to recast this financial
information.

     The net operating margin from pipeline operations for the two months ended
June 30, 1998 was $1,742,000 compared to $1,730,000 for the three months ended
July 31, 1997.  The margin per gallon for the two months ended June 30, 1998 of
$.0096 increased 17% or $.0014.  The increase resulted primarily from a 30%
increase in barrels per day thruput volume of approximately 16,500 barrels per
day, primarily due to an increase in volumes of both higher tariff long haul
pipeline shipments and crude oil pipeline shipments.  The revenue increase was
partially offset by an increase in operating costs which was due to incremental
power costs attributable to additional long haul shipments and crude oil
pipeline shipments volumes and increased field personnel costs, maintenance and
vehicle expense.

     The net operating margin from terminal and storage operations for the two
months ended June 30, 1998 was $2,413,000 compared to $1,450,000 for the three
months ended July 31, 1997.  The margin per gallon for the two months ended June
30, 1998 of $.0060 increased 18% or $.0009.  The increase resulted from an
increase in refined petroleum products volumes handled and volumes of chemicals
and other bulk liquids not previously handled, primarily due to the operations
of the ITAPCO Terminal Corporations terminal facilities acquired in November
1997; a 91% increase in barrels per day volumes handled at the East Chicago
terminal facility; and a 91% increase in barrels per day volumes handled at the
Indianapolis, Indiana terminal. The revenue increases were partially offset by
increases in terminal operating costs largely attributable to the ITAPCO
Terminal Corporations terminals operations; expanded East Chicago terminal
operations; additional freight charges on products; and increased field
personnel costs and maintenance expenses.

                                       25

     The net operating loss from product sales for the two months ended June 30,
1998 was $3,951,000 compared to a net operating margin of $3,580,000 for the
three months ended July 31, 1997. Revenues were $299,351,000 for the two months
ended June 30, 1998 compared to $442,583,000 for the three months ended July 31,
1997. A $.0061 net operating loss per gallon was realized in the two months
ended June 30, 1998 compared to $.0047 net operating margin per gallon realized
for the three months ended July 31, 1997. Volatile refined petroleum product
market conditions influenced by the lack of product demand, instability in the
international political climate and atypical and erratic weather patterns drove
product prices to unanticipated historical lows which had a direct and adverse
affect on products supply and distribution performance for the two months ended
June 30, 1998. In addition, a lower of cost or market write down adjustment to
inventory of $1,880,000 as of June 30, 1998 was charged to product costs
resulting in a $.0029 net operating loss per gallon sold during the two months
ended June 30, 1998. An inventory adjustment of this nature was not recorded for
the three months ended July 31, 1997.

     The net operating margin from natural gas services operations for the two
months ended June 30, 1998 was $2,209,000 compared to $3,435,000 for the three
months ended July 31, 1997.  Revenues for the two months ended June 30, 1998 was
$9,400,000 compared to $14,218,000 for the three months ended July 31, 1997.
The net operating margin and revenues were attributable primarily to the
business activities of the Grasslands Facilities, and also included net
operating margin contributions and revenues from the Marmarth, Baker, Lignite
and Wiggins natural gas gathering and processing facilities, as well as
management fees from fifteen small natural gas gathering systems.  Net operating
margin and revenues during the two months ended June 30, 1998 were impacted by a
steep decline in NGL prices, primarily propane, notwithstanding an approximate
20% increase in natural gas inlet volumes per day.

     General and administrative expenses for the two months ended June 30, 1998
were $3,225,000 compared to $2,783,000 for the three months ended July 31, 1997.
The increase was due primarily to additional personnel related costs and to
increased office lease, regulatory reporting, travel, insurance, information
systems and communication expenses. These increases were directly attributable
to the acquisition and operations of the ITAPCO Terminal Corporations and to
TransMontaigne's overall expansions of its expanded integrated logistical
petroleum services.

                                       26

     Other income for the two months ended June 30, 1998 included interest
income of $290,000 compared to $565,000 for the three months ended July 31,
1997. The decrease in interest income was due primarily to the decrease in
interest bearing cash balances held for future investments.

     Interest expense represents interest on the TransMontaigne bank credit
facility and senior promissory notes which were used primarily to finance the
acquisitions of the ITAPCO Terminal Corporations in November, 1997 and
Grasslands Facilities in December, 1996, other continuing capital expenditures
and working capital to carry inventory and accounts receivable.  Also included
is interest on the TransMontaigne senior subordinated debentures.  Other
financing costs principally include commitment fees and amortization of debt
acquisition costs paid in connection with the credit facility.  Interest expense
and other financing costs during the two months ended June 30, 1998 amounted to
$1,769,000 compared to $1,643,000 during the three months ended July 31, 1997.
The increased interest expense was due primarily to an increase in average
outstanding debt to fund the ITAPCO Terminal Corporations acquisition.

     Loss before income taxes for the two months ended June 30, 1998 was
$4,066,000, compared to earnings before income taxes of $4,610,000 for the three
months ended July 31, 1997.  The loss was primarily a result of severely
depressed product prices which caused negative product sales operating margins;
increased general and administrative expenses; additional depreciation
attributable to the expansion of natural gas services assets and the acquisition
of the ITAPCO Terminal Corporations; and interest expense, primarily
attributable to the financing of the Grassland Facilities and ITAPCO Terminal
Corporation acquisitions.  Partially offsetting these factors were the operating
margin contribution from the ITAPCO Terminal Corporations acquisition; the net
operating margin contribution from the natural gas services business segment
attributable essentially to the Grasslands Facilities; and the increased net
operating margin contribution from the pipeline operations business segment.
 
     Income tax benefit for the two months ended June 30, 1998 of $1,403,000 and
the income tax expense of $1,600,000 for the three months ended July 31, 1997 is
based upon an effective combined federal and state income tax rate of 35%.

                                       27
<PAGE>
 
     Net loss for the two months ended June 30, 1998, after providing for the
income tax benefit, was $2,663,000 compared to net earnings of $3,010,000 for
the three months ended July 31, 1997.  Loss per share for the two months ended
June 30, 1998 was $ .10 basic and $.10 diluted based on 25,948,709 weighted
average basic shares outstanding and weighted average diluted shares
outstanding.  This compares to earnings per share of $ .12 basic and $ .11
diluted for the three months ended July 31, 1997.


LIQUIDITY AND CAPITAL RESOURCES

     Net cash provided by financing activities             $      12,000        14,188,000
</TABLE>

     TransMontaigne's net cash provided by operating activities in the two
months ended June 30, 1998 was $3,672,000 an improvement of $8,082,000 compared
to the three months ended July 31, 1997. This improvement was attributable
primarily to the net change in operating assets and liabilities of $16,646,000
reduced by the decrease in earnings before income taxes of $8,675,000. The lower
of cost or market adjustment to inventory did not affect TransMontaigne's net
cash provided by operating activities. TransMontaigne's current ratio (current
assets divided by current liabilities) was 3.0 to 1.0 at June 30, 1998 compared
to 2.5 to 1.0 at July 31, 1997.

     Net cash used by investing activities was $6,276,000 during the two months
ended June 30, 1998 as TransMontaigne continued its growth through construction
and improvements to existing operating facilities. Capital expenditures included
enhancements to the East Chicago, South Bend, and North Little Rock facilities
and several of the purchased ITAPCO terminals; improvements to the NORCO
Pipeline facilities; expansion to assets in the natural gas services business
segment; and

                                       28
<PAGE>
 
additions to TransMontaigne's corporate communications and data processing
infrastructure. Net cash used by investing activities was $4,896,000 during the
three months ended July 31, 1997 which included approximately $2,900,000
improvements to the Grasslands Facilities and other assets in the natural gas
services business segment; and improvements to the pipeline and terminal
facilities.

     Net cash provided by financing activities for the two months ended June 30,
1998 amounted to $12,000. Net cash provided by financing activities for the
three months ended July 31, 1997 amounted to $14,188,000 was used to finance
operations and capital expenditures primarily through an increase in cash
borrowings. At June 30, 1998, TransMontaigne had $279,000,000 of borrowing
capacity with availability of $147,400,000 under its credit agreements.

     EBITDA represents earnings before income taxes plus interest expense and
other financing costs and depreciation and amortization. Management uses EBITDA
as part of its overall assessment of TransMontaigne's performance by analyzing
and comparing EBITDA between reporting periods.  Management believes that, in
addition to cash flow from operations and net earnings as indicators of
operating performance, EBITDA is used increasingly by the financial community to
measure operating effectiveness and as a method to evaluate the market value of
companies like TransMontaigne.  EBITDA is also used to evaluate TransMontaigne's
ability to incur and service debt and to fund capital expenditures, although it
is not considered in isolation or a substitute for the other measurements of
performance and liquidity.  EBITDA for the two months ended June 30, 1998 was a
negative $523,000 compared to EBITDA of $7,976,000 for the three months ended
July 31, 1997.  EBITDA for the two months ended June 30, 1998 was adversely
impacted by severely depressed products prices, increased general and
administrative expenses, and reduced interest income.  In addition, EBITDA also
reflects a charge to product costs for the lower of cost or market write down
adjustment to inventory as of June 30, 1998.  An inventory adjustment of this
nature was not recorded for the three months ended July 31, 1997.  The decreases
in EBITDA were partially offset by EBITDA contributions by the ITAPCO Terminal
Corporations and increased EBITDA of the pipeline operations business segment.
Achieving continued EBITDA growth through acquisitions and internal expansion of
existing facilities is a primary objective of TransMontaigne.

                                       29
<PAGE>
 
     Capital expenditures anticipated in the year ending June 30, 1999 are
estimated to be approximately $250,000,000 for pipeline, terminal, storage and
natural gas gathering and processing facilities, including assets to support
these facilities, and including the West Shore Pipe Line Company and Statia
Terminals Southwest, Inc. acquisitions and the contemplated Louis Dreyfus Energy
Corp. acquisition. This amount could be exceeded if additional facilities
enhancement projects and possible acquisitions being considered by
TransMontaigne materialize. Future capital expenditures will depend on numerous
factors, including the availability, economics and cost of appropriate
acquisitions which TransMontaigne continuously identifies and evaluates; the
economics, cost and required regulatory approvals with respect to the expansion
and enhancement of existing systems and facilities; the demand for the services
TransMontaigne provides; local, state and federal governmental regulations;
environmental compliance requirements; fuel conservation efforts; and the
availability, to the extent required, of financing on acceptable terms.

     In February 1997, TransMontaigne closed a public offering of 4,357,000
shares of its common stock of which 4,035,000 shares were issued and sold by
TransMontaigne and 322,000 shares were sold by certain selling stockholders.
The net proceeds to TransMontaigne, based on the public offering price of $14.25
per share, were $53,506,000 after deducting underwriting discounts and
commissions and offering costs, of which $45,000,000 was used to repay a portion
of the long-term debt incurred under its bank credit facility and the balance
was added to working capital. In March 1997 the underwriters' overallotment
option to purchase an additional 557,543 shares and the Merrill Lynch Growth
Fund antidilution right to purchase an additional 98,390 shares were both
exercised and TransMontaigne received additional net proceeds of $8,809,000
which was added to working capital.  The total net proceeds from the offering
was $62,315,000.

     The TransMontaigne bank credit facility at June 30, 1998 is a $175,000,000
revolving credit facility with a money center bank due December 31, 2002.
Borrowings under the bank credit facility generally bear interest paid in
arrears at an annual rate equal to the lenders' announced rate on Alternate Base
Rate loans, subject to a Eurodollar Rate loan pricing election.  In addition, a
$10,000,000 same day swing line of credit is available to TransMontaigne under
which advances may be drawn at an interest rate comparable to the Eurodollar
Rate.

     As of June 30, 1998, TransMontaigne had advances of $50,000,000 outstanding
under the bank credit facility utilizing the Eurodollar Rate loan pricing
election and $2,600,000 of the facility was used to support a standby letter of
credit to a bank to assist Lion Oil Company in obtaining financing. The interest
rate at June 30, 1998 was 6.375%.

     In April 1997 TransMontaigne entered into a Master Shelf Agreement with an
institutional lender which provides that the lender will agree to quote, from
time to time, an interest rate at which the lender would be willing to purchase,
on an uncommitted basis, up to $100,000,000 of TransMontaigne's senior
promissory notes which will mature in no more than 12 years, with an average
life not in excess of 10 years.

     At June 30, 1998, TransMontaigne had outstanding under the Master Shelf
Agreement, $50,000,000 of 7.85% Senior Notes due April 17, 2003 and $25,000,000
of 7.22% Senior Notes due October 17, 2004.

     The bank credit facility agreement and the Master Shelf Agreement contain a
negative pledge covenant by TransMontaigne and its subsidiaries and are secured
by the stock of the subsidiaries.  These agreements also include financial tests
relating to fixed charges coverage, leverage ratio, consolidated tangible net
worth, distributions and inventory positions.  As of June 30, 1998,
TransMontaigne was in compliance with all such tests.

     As of June 30, 1998, TransMontaigne had approximately $22,000,000 of net
operating loss carryforwards for federal income tax purposes which are available
to offset taxable income through 2017. As a result of the merger in June 1996,
TransMontaigne acquired net operating loss carryforwards of approximately
$7,892,000 as of June 4, 1996, which are included in the aggregate net operating
loss carryforwards, and are limited to approximately $1,200,000 annually.  A
portion of the tax benefit of such carryforwards has been recognized as a net
reduction of goodwill recorded in the merger.  Due to changes in ownership which
occurred through April 30, 1996, the use of the remaining net operating loss
carryforwards to offset taxable income is limited to approximately $4,300,000
annually.

     At June 30, 1998, TransMontaigne had working capital of $86,467,000;
availability under its bank credit facility of $122,400,000; and additional
borrowing capacity of $25,000,000 under the Master Shelf Agreement.

     Management believes that TransMontaigne's current working capital position;
future cash provided by operating activities; proceeds from the private
placement or public offering of debt and common stock; available borrowing
capacity under the bank credit facility agreement and the Master Shelf
Agreement; additional borrowing allowed under those agreements; and its
relationship with institutional lenders and equity investors should enable
TransMontaigne to meet its future capital requirements.


YEAR 2000 MATTERS

     Historically, certain computer programs, as well as certain hardware, were
designed to utilize a two-digit date field and consequently, they may not be
able to properly recognize dates in the Year 2000.  This could result in
significant system failures.  TransMontaigne relies on its computer-based
management information systems, as well as computer chip embedded instruments
and equipment in conducting its normal business activities.  Certain of these
computer-based programs and embedded computer chips may not have been designed
to function properly with respect to the application of dating systems relating
to the Year 2000.

     In response, TransMontaigne has developed a "Year 2000" Plan and
established an internal group to identify and assess potential areas of risk and
to make any required modifications relating to its computer systems; pipeline,
terminaling, storage and natural gas gathering and processing operations; and
product supply and distribution activities.  After these assessments are
completed and evaluated, plans for modification or replacement, testing, and
certification will be developed and implemented to ensure that the material
facilities and business activities will continue to operate safely and reliably,
and without interruption after 1999.  TransMontaigne is also monitoring the
compliance efforts of suppliers, contractors and other third parties with whom
it does business to ensure that operations will not be adversely affected by the
Year 2000 compliance problems of others.

                                       32

     While TransMontaigne is not yet able to estimate the total costs of
conducting Year 2000 remedial activities, based upon information developed to
date, it believes that the total cost of Year 2000 remediation will not be
material to TransMontaigne's cash flow, results of operations, or financial
condition.  TransMontaigne expects to complete its Year 2000 Plan within a time
frame that will enable its computer-based and embedded chip systems to function
without significant disruption in the Year 2000.

     The discussion of TransMontaigne's efforts, and management's expectations,
relating to Year 2000 compliance contains forward-looking statements.
Presently, TransMontaigne does not anticipate that the Year 2000 will have a
material adverse effect on its operations or financial performance.  However,
there can be no assurance that the Year 2000 will not adversely affect
TransMontaigne and its business.


NEW ACCOUNTING STANDARDS

     Statement of Financial Accounting Standards No. 131, "Disclosures about
Segments of an Enterprise and Related Information" ("SFAS 131"), which was
issued June 1997, by the Financial Accounting Standards Board.  SFAS 131
established new standards which change the way public companies report
information about segments.  This statement is based on the management approach
to segment reporting and requires companies to report selected quarterly segment
information and entity-wide disclosures about products and services, major
customers and geographic areas in which the entity holds assets and reports
revenues.  SFAS 131 is effective for financial statements for fiscal years
beginning after December 31, 1997.  TransMontaigne does not expect the adoption
of SFAS 131 to have a material effect on the presentation of its financial
statements.

     Statement of Financial Accounting Standards No. 133, "Accounting for
Derivative Instruments and Hedging Activities" ("SFAS 133"), was issued in June
1998, by the Financial Accounting Standards Board. SFAS 133 establishes new
accounting and reporting standards for derivative instruments and for hedging
activities. This statement requires an entity to establish at the inception of a
hedge, the method it will use for assessing the effectiveness of the hedging
derivative and the

                                       33
<PAGE>
 
measurement approach for determining the ineffective aspect of the hedge. Those
methods must be consistent with the entity's approach to managing risk. SFAS 133
is effective for all fiscal quarters of fiscal years beginning after June 15,
1999. TransMontaigne has not assessed the impact, if any, that SFAS 133 will
have on its consolidated financial statements.

common stock to a consultant to TransMontaigne pursuant to the terms of a
consulting agreement for services rendered in connection with an asset
acquisition.  Because the issuance occurred in a privately negotiated
transaction that did not involve a public offering, the shares of
