Item 2.  ACQUISITION OR DISPOSITION OF ASSETS

Between March 10 and March 13, 1998, Kirby Corporation ("Kirby") consummated an
Asset Purchase Agreement dated as of January 28, 1998 by and between Kirby,
Kirby's wholly-owned subsidiaries, Sabine Transportation Company (a Delaware
corporation) and Kirby Tankships, Inc. (collectively the "Kirby Subsidiaries")

The purchase price was determined through arms-length negotiation between

Colorado and one additional Vessel owned by Sabine to STCI at the port of Port
Arthur, Texas on March 9, 1998, conditioned upon the delivery by STCI to Sellers
of the documents and certificates described in Section 6.3 and payment of the
portions of the Purchase Price allocated to such Vessels on Schedule 1.3. The
remaining tank vessels shall be delivered by the respective Sellers to the
respective Buyers during the Closing Period; provided, however, that Sellers'
delivery of a Notice of Readiness for Delivery in accordance with this Section
9.2 during the Closing Period shall constitute delivery of the related tank
vessel within the Closing Period. Delivery of tank vessels by Sellers to Buyers
and payment by Buyers to Sellers shall be performed in the manner and on the
terms and conditions more fully set forth below.

         Sellers shall deliver each tank vessel to its respective Buyer at a
berth mutually agreed upon between such Buyer and Sellers (the "Nominated
Berth") at a U.S. Gulf Port nominated by the Buyer (the "Delivery Port"), unless
otherwise mutually agreed between Seller and Buyer. Buyer shall nominate the
Delivery Port no later then 10 days prior to the commencement of the Closing
Period. Sellers shall give Buyers 7/6/5/4/3/2/1 days notice of the arrival of
each tank vessel at the Delivery Port. Upon the safe arrival of the tank vessel
at its Nominated Berth, Seller shall deliver to Buyer its Notice of Readiness
for Delivery, which shall state that the Vessel is in all respects ready for
delivery to Buyer.

         Within two banking days of the Buyer's receipt of the Notice of
Readiness for Delivery, the Buyer shall transfer to Seller by wire transfer the
purchase price of the Vessel as set forth in Schedule 1.3 (the "Funds").
Immediately upon confirmation of the wire transfer of Funds by Buyer, Seller
shall deliver to Buyer the Vessel and the documents listed in Section 7.5 with
respect to the Vessel. It is recognized and agreed, however, that STCI will not
take delivery of any Vessel during pendency of a voyage.

         Sellers shall deliver each tank vessel to its respective Buyer at the
Nominated Berth safely afloat, virtually intact, free of fire damage, free of
arms, and ammunitions. Except for the tank vessels being purchased by Hvide,
which may be delivered prior to completion of a voyage, such Vessel shall be
free of cargo and charter and, provided that the Delivery Port is Port Arthur,
Texas, also free of slops.

                                       18

   19



         Upon berthing of a Vessel at the Nominated Berth, its respective Buyer
shall have immediate access to the Vessel for purposes of familiarization of
Buyers' crew with the operation of the Vessel and the transition of crews; tank
cleaning and construction of rose boxes; inspections in preparation for cargo
loading; and such other purposes as may be reasonably necessary for Buyer to
prepare to take control of and operate the vessel. The Buyer shall provide such
standard indemnities as may be required by the Sellers.

         9.3 Voyages in Progress.

         (a) For purposes of this Section 9.3, the following terms shall have
the meanings indicated:

                  (i) "Gross Revenues" means all payments received from the
         customer for a voyage in progress, whether received by Hvide or the
         Seller and whether received before or after the Closing.

                  (ii) "Reimbursements" means the portion of Gross Revenues for
         a voyage in progress that represents reimbursement for direct expenses
         of the voyage.

                  (iii) "Net Revenues" for a voyage in progress means Gross
         Revenues minus Reimbursements.

         (b) With respect to the Closing of the purchase by Hvide of any tank
vessel engaged in a voyage in progress on the date of the Closing of such
purchase:

                  (i) Net Revenues for that voyage shall be shared by Hvide and
         the Seller in proportion to the number of days of the voyage during
         which each party was the owner of the Vessel;

                  (ii) fuel expense shall be shared by Hvide and the Seller in
         proportion to the number of days of the voyage during which each party
         was the owner of the Vessel;

                  (iii) except as provided in Section 9.3(b)(ii), Hvide and the
         Seller shall each bear the direct expenses of the voyage attributable
         to the period during which such party was the owner of the Vessel; and

                  (iv) Hvide and the Seller each shall be entitled to the
         Reimbursements for the expenses borne by it.

For purposes of this Section 9.3(b), the Seller will be considered the owner of
the Vessel prior to the date of the Closing and Hvide will be considered the
owner of the Vessel on and after such date.


                                       19

   20



         (c) Net payments due from Sellers to Hvide or from Hvide to Sellers, as
the case may be, for all voyages in progress on the date of the Closing shall be
made within 30 days after the Closing. Each party shall have reasonable access
to the books and records of the other in order to verify the revenues and
expenses for voyages in progress.

         9.4 Loss or Damage. Should any Vessel become an actual, constructive,
or compromised total loss (the "Damaged Vessel") before delivery to the Buyer,
the Buyer shall have the option exercisable at its sole discretion, to either
purchase the Damaged Vessel at the assigned price subject to P&I Club's and
Underwriters' consent to assignment of payments on claims or, in the
alternative, may declare this Agreement null and void with respect to the
Damaged Vessel alone and take delivery of the remainder of the Vessels upon
payment of the respective purchase prices set forth in Schedule 1.3.

SECTION 10.  INDEMNIFICATION.

         10.1 By the Sellers. The Sellers shall jointly and severally indemnify
Buyers in respect of, and hold them harmless against, any and all debts,
obligations, and other liabilities (whether absolute, accrued, contingent, fixed
or otherwise, or whether known or unknown, or due or to become due or
otherwise), monetary damages, forfeitures, fines, fees, penalties, interest
obligations, deficiencies, losses and expenses (including amounts paid in
settlement, interest, court costs, costs of investigators, reasonable fees and
expenses of attorneys, accountants, financial advisors and other experts, and
other expenses of litigation, investigations, inquiries by governmental bodies
or related proceedings ("Losses")) incurred or suffered by Buyers or any
affiliate of Buyers resulting from (i) the material breach of any
representation, warranty, covenant, guarantee, or agreement of the Sellers
contained in this Agreement and (ii) Sellers' use of the Assets prior to
Closing..

         10.2 By the Buyers. Each Buyer shall severally, but not jointly,
indemnify the Sellers in respect of, and hold the Sellers harmless against, any
and all Losses incurred or suffered by the Sellers or their affiliates resulting
from (i) the breach of any material representation, warranty, covenant, or
agreement of such Buyer contained in this Agreement and (ii) such Buyer's use of
the Assets after the Closing.

         10.3 Notification; Third Party Claims. Each party shall notify the
other in writing as promptly as practicable whenever it shall determine that
there are facts or circumstances that render the other liable to such party
under this Section 10. In addition, in the event that any suit, action, or
proceeding shall be brought by any third party which, if successful, would
render any party liable to the other party under this Section 10, then the party
seeking indemnification hereunder (the "Indemnitee") shall, as promptly as
practicable after the service of process commencing such suit, action or
proceeding, give notice thereof to the party from whom indemnification is sought
(the "Indemnitor"). Upon receipt of such notice, the Indemnitor may elect to
assume the control of the defense of such suit, action, or proceeding with
counsel of its choice, and

                                       20

   21



after written notice from the Indemnitor to the Indemnitee of its election so to
assume the control of such defense, the Indemnitee shall not be liable to the
Indemnitor for any costs or expenses incurred by the Indemnitor in connection
with such defense, nor for any judgment, damages, claims, or penalties rendered
or assessed in connection with any such suit, action, or proceeding, nor for any
losses or damages resulting from the settlement of any such suit, action, or
proceeding if settled by the Indemnitor without the written consent of the
Indemnitee.

         10.4 Limitation on Losses. For purposes of any indemnification pursuant
to this Section 10, Losses shall be determined after giving effect to insurance
proceeds and recoveries from third parties and shall in no event include lost
profits or consequential or similar damages.

         10.5 Sole Recourse. The indemnification provided in this Section 10
shall be the sole recourse of any party hereto for any breach by any other party
of any representation, warranty, covenant, guarantee, or agreement contained in
this Agreement.

SECTION 11.  TERMINATION.

         11.1  Termination. This Agreement may be terminated at any time prior

         Buyers; or

                  (ii)  by the Sellers or the Buyers if

                       (A) any court or governmental body of competent
                  jurisdiction shall have issued an order, decree, or ruling, or
                  taken any other action, permanently restraining, enjoining, or
                  otherwise prohibiting the transactions contemplated by this
                  Agreement, provided that no termination shall be permitted
                  under this paragraph unless the party seeking such termination
                  shall have used its reasonable best efforts to oppose such
                  issuance or action; or

                       (B) the other party commits any material breach of its
                  representations, warranties, or covenants set forth herein and
                  such breach has not been cured within seven days after notice
                  is given to terminate this Agreement as a result of such
                  breach; or

                  (iii) by the Sellers if the conditions set forth in Section 6
         have not been satisfied, other than through failure of Sellers to
         comply with their obligations hereunder, or waived by April 30, 1998
         (the "Termination Date"), and by the Buyers if the conditions set forth
         in Section 7 have not been satisfied, other than through failure of
         Buyer to comply with its obligations hereunder, or waived by the
         Termination Date.


                                       21

   22



         11.2 Effect of Termination. In the event this Agreement is terminated
pursuant to Section 11.1, all further obligations of the parties hereunder shall
terminate. No termination of this Agreement shall act to terminate or otherwise
impair the obligations set forth in Sections 5.13 and 13.2.

         11.3 Termination Concerning Real Property. Hvide may terminate its
obligation to purchase the Real Property and Sellers' obligation to deliver the

of its due diligence investigation of environmental risks relating to the Real
Property, it has determined not to purchase the Real Property.

SECTION 12.  GUARANTEE

         12.1 Hvide's Guarantee. Hvide unconditionally guarantees the full and
timely payment by STCI of its portion of the Purchase Price under this
Agreement.

SECTION 13.  MISCELLANEOUS.

         13.1 Survival of Representations and Warranties. Every representation
and warranty of each of the parties set forth in this Agreement and all of the
rights and remedies of the other parties related to misrepresentations and
inaccuracies related thereto shall survive, and not be deemed waived by, the
Closing, and shall be effective regardless of any investigation that may have
been made at any time by or on behalf of any party or its directors, officers,
employees, or agents.

         13.2 Expenses. Except as otherwise provided in Section 11.2 hereof, the
parties shall pay their respective expenses (including the fees, disbursements,
and expenses of their respective attorneys and accountants) in connection with
the negotiation and preparation of this Agreement and the consummation of the
transactions contemplated hereby.

         13.3 Notices. Each party hereto shall promptly give written notice to
the other parties upon becoming aware of the occurrence of, or any impending or
threatened occurrence of, any event that would cause or constitute a breach of
any of its representations, warranties, or covenants contained in this
Agreement, and such party shall use its best efforts to prevent or promptly
remedy the same. Any notice or other communication required or which may be

Any party may change its address to which notices or other communications are to
be sent by giving written notice of any such change in the manner provided
herein for giving notice.

         13.4 Modification or Waiver. This Agreement may be amended, modified,
or superseded at any time by a written instrument executed by the Sellers and
the Buyers, and any of the terms, covenants, representations, warranties, or
conditions hereof may be waived by written instrument executed by the party
intended to be benefited thereby. No waiver of any nature, in any one or more
instances, shall be deemed to be or construed as a further or continued waiver
of any condition or any breach of any other term, representation, or warranty in
this Agreement.

         13.5 Binding Effect and Assignment. This Agreement shall be binding
upon and inure to the benefit of the parties hereto and their respective
successors and assigns; provided, however, that prior to the Closing Date, no
assignment of any rights provided for herein may be made by any party without
the written consent of the other parties which consent shall not be unreasonably
withheld.

         13.6 Governing Law.  This Agreement shall be governed by and construed
in accordance with the laws of the state of Florida.

         13.7 Section Headings. The Section headings contained in this Agreement
are inserted for convenience of reference only and shall not affect the meaning
or interpretation of this Agreement.

         13.8 Further Assurances. Subject to the terms and conditions herein
provided, each of the parties agrees to use all reasonable efforts to take, or
cause to be taken, all action and to do, or cause to be done, all things
necessary, proper, or advisable under applicable laws and regulations to
consummate the purchase and sale of the Assets in accordance with the terms of
this Agreement. In case at any time any further action is necessary or desirable
to carry out the purposes of this Agreement, the appropriate officers of each
party to this Agreement are hereby directed and authorized to use their good
faith efforts to effectuate all such action.

         13.9 Entire Agreement. This agreement embodies the entire agreement and

         13.10 No Third Party Beneficiaries. Nothing expressed or referred to in

   25



         13.11 Counterparts. Separate copies of this Agreement may be signed by

provision and, to this end, the provisions hereof are severable.

         13.14 Interpretation of Agreement. The parties hereto acknowledge and
agree that this Agreement has been negotiated at arm's length and between
parties equally sophisticated and knowledgeable in the matters dealt with in
this Agreement. Accordingly, any rule of law, court decision, or other legal
precedent that would require interpretation of any ambiguities in this Agreement
against the party that has drafted it is not applicable and is waived. The
parties hereto also acknowledge and agree that this Agreement pertains to the
purchase and sale of certain defined assets and, notwithstanding anything to the
contrary herein, shall be interpreted as such and not as pertaining to the
purchase and sale of any of the Sellers or their businesses as going concerns.
Sellers recognize that Buyers have relied upon information regarding the
Business in conducting their due diligence with respect to the Assets.

         13.15 Arbitration. Should any dispute arise out of this Agreement with
respect to the purchase and sale of the Vessels, the matter in dispute shall be
referred to arbitration in New York City. The arbitrators shall be commercial
persons conversant with shipping matters. Unless the parties agree upon a sole
arbitrator, one arbitrator shall be appointed by the Buyer and one arbitrator
shall be appointed by the Seller, and a third arbitrator shall be appointed by
the two so chosen. If either of the appointed arbitrators refuses to act or is
incapable of acting, the party who appointed the arbitrator shall appoint a new
arbitrator in his or her place. If one party fails to appoint an arbitrator,
whether originally or by way of substitution, for two weeks after the other
party, having appointed its arbitrator, has (by telefax or letter) called upon
the defaulting party to make the appointment, the Society of Maritime
Arbitrators, Inc. shall, upon application of the other party, appoint an
arbitrator on behalf of the defaulting party and that arbitrator shall have the
like powers to act in the reference and make an award (and, if the case so
requires, the like duty in relation to the appointment of a third arbitrator) as
if he had been appointed by a party to this Agreement in accordance with the
terms of this Clause. The proceedings under this Section 13.16 shall be
conducted in accordance with the Rules of the Society of Maritime Arbitrators,
Inc. as in effect at the time the arbitration proceedings commence.

         The arbitration award may grant any remedy or relief deemed by the
arbitrators to be just and equitable, including specific performance of this
Agreement; provided,

                                       25

   26



however, that the arbitrators shall not be empowered to award consequential or
punitive damages nor any other damages in excess of actual damages. Judgment on
any award rendered by the arbitrators may be entered in any court having
jurisdiction thereof.

         3.16 General Disclaimer. Except as set forth in Section 2 of this
Agreement, neither Sellers nor anyone acting on their behalf has made any
further representation or warranty, either express or implied, concerning the
subject matter of this Agreement and the transactions contemplated hereby,
including any such further representation or warranty concerning the physical
nature or condition of the Real Property, the existence or nonexistence of
Materials of Environmental Concern on, at, or under the Real Property, or use of
the Real Property, and Buyers have not relied on any such further representation
or warranty. This Agreement shall not be governed by the warranties provided by
the Uniform Commercial Code as adopted in any jurisdiction. Except for
representations and warranties expressly set forth in this Agreement, the
Schedules hereto, and the documents delivered as the Closing, no other
representations or warranties, either express or implied, have been made by or
on behalf of Sellers or relied upon by Buyers. OTHER THAN REPRESENTATIONS,
WARRANTIES, COVENANTS AND AGREEMENTS CONTAINED IN THIS AGREEMENT, ANY INSTRUMENT
OF CONVEYANCE OR OTHER DOCUMENT EXECUTED AND DELIVERED PURSUANT TO THIS
AGREEMENT, BUYERS (a) UNDERSTAND AND AGREE THAT NEITHER SELLERS NOR ANYONE
ACTING ON THEIR BEHALF MAKE ANY EXPRESS OR IMPLIED REPRESENTATIONS OR WARRANTIES
WITH RESPECT TO THE BUSINESS, ASSETS OR ASSUMED OBLIGATIONS REFERRED TO HEREIN,
THE SEAWORTHINESS, CONDITION OR WORKMANSHIP OF ANY ASSET, OR THE ABSENCE OF ANY
DEFECTS THEREIN, WHETHER LATENT OR PATENT, OR THE CAPACITY, STABILITY, UTILITY,
SALABILITY, OPERATION, CONDITION, MERCHANTABILITY OR FITNESS FOR ANY PURPOSE OR
A PARTICULAR PURPOSE THEREOF AND (b) ACCEPT SUCH ASSETS AND VESSELS ON AN "AS
IS, WHERE IS, WITH ALL FAULTS" BASIS. BUYERS ASSUME THE FULL RISK OF FUTURE
PROSPECTS, CONTINUATION OF RELATIONSHIPS WITH CUSTOMERS AND SUPPLIERS, AS WELL
AS THE BUSINESS AND FINANCIAL RISK, INCLUDING THE NEED FOR SUBSTANTIAL WORKING
CAPITAL, IN CONNECTION WITH THE OPERATION OF THE BUSINESS AFTER THE CLOSING.

         3.17 Oil Pollution Act. Buyers are familiar with the provisions of the
Oil Pollution Act of 1990, which will have a material impact with respect to the
tank vessels included in the Vessels, all of which are of single-hull
construction. Buyers understand that the Oil Pollution Act of 1990 imposes
limitations on the useful lives of all such tank vessels for purposes of their
operation in U.S. waters.

         13.18 Books and Records; Personnel. For a period of seven years from
the Closing Date (or such longer period as may be required by any governmental
agency or requested by Sellers in connection with disputes or litigation):

         (a) Buyers shall neither dispose of nor destroy any of the books and
records delivered to Buyers in connection with the Closing without first
offering to turn over

                                       26

   27



possession thereof to Sellers by written notice to Sellers at least 30 days
prior to the proposed date of such disposition or destruction;

         (b) Buyers shall allow Sellers and their agents reasonable access to
such books and records during normal working hours at the offices of Buyers at
which such books and records are located; and

         (c) Buyers shall make available to Sellers upon written request
therefor (i) copies of any such books and records, (ii) Buyers' personnel to
assist Sellers in locating and obtaining any such books and records, and (iii)
any of Buyers' personnel who were employed by Sellers prior to the Closing Date
and whose assistance or participation is reasonably required by Sellers in
connection with existing or future litigation, tax returns or other matters in
which Sellers are involved. Sellers shall reimburse Buyers for the reasonable
out-of-pocket expenses incurred by Buyers in performing the covenants contained
in this Section 13.18.

                                       27
