         The C/R Purchasers entered into the Purchase Agreements in order to
acquire an interest in the Company for investment purposes. The Reporting
Persons intend to review continuously their position in the Company. Depending
upon further evaluations of the business prospects of the Company and other
developments, including but not limited to, general economic and business
conditions and stock market conditions, the Reporting Persons may retain or,
from time to time, increase their holdings or dispose of all or a portion of
their holdings subject to any applicable legal and contractual restrictions on
their ability to do so in privately negotiated transactions, open market
purchases or otherwise.

         The Reporting Persons also intend to actively participate in the
management of the Company through representation on the Board of Directors.
Pursuant to a Stockholders' Agreement (as defined in Item 6 below), to be
entered into by and among the Company, the C/R Purchasers, Nautilus and a
management shareholder, certain of the C/R Purchasers and Nautilus will agree to
vote their shares to ensure that the Board of Directors will consist of ten
directors and will include two directors designated by certain of the C/R
Purchasers and four directors designated by Nautilus.

         As part of the transactions contemplated by the Company Stock Purchase
Agreement, the Company will amend its certificate of incorporation to add, among
other things, certain protections for minority stockholders.

         In addition, the matters set forth in Item 6 below are incorporated in
this Item 4 by reference as if fully set forth herein.

         Except as set forth in this Item 4 (including the matters described in
Item 6 below which are incorporated in this Item 4 by reference), the Reporting
Persons have no present plans or proposals that relate to or that would result
in any of the actions specified in clauses (a) through (j) of Item 4 of Schedule
13D of the Securities Exchange Act of 1934, as amended (the "Exchange Act").


                                       8



Item 5.       Interest in Securities of the Issuer.

                  (a)-(b) As of July 16, 2002, neither the Reporting Persons nor
Nautilus was the holder of record of any shares of Common Stock or Warrants. On
July 9, 2002, the Company filed its preliminary proxy statement seeking
stockholder approval of the share issuance to the C/R Purchasers and Nautilus
pursuant to the Company Stock Purchase Agreement and of the amendment to its
certificate of incorporation with the Securities and Exchange Commission. Also
on July 9, 2002, early termination of the waiting periods under the
Hart-Scott-Rodino Antitrust Improvements Act of 1974, as amended ("HSR Act"),
was granted.

         If the transactions contemplated by the Purchase Agreements are
consummated, each of the Reporting Persons and Nautilus may be deemed to
beneficially own the following:

---------
(1)  These numbers may decrease to the extent that Loomis Sayles can no longer
     cause such shares or Warrants to be sold to a C/R Purchaser. See Item 6
     below for a description of the Loomis Securities Purchase Agreement. Each
     of the C/R Purchasers will have the shared power to dispose or direct the
     disposition of the shares of Common Stock and Warrants which it would hold
     directly or the shares of Common Stock issuable upon exercise of such
     Warrants. Each of the C/R Purchasers will have the shared power to vote or
     direct the vote of such shares of Common Stock, but will not have the power
     to vote or direct the vote of any of the shares of Common Stock which it
     would own upon exercise of such Warrants prior to the receipt of such
     shares of Common Stock upon exercise of such Warrants. The C/R Purchasers
     may be deemed to be acting as a group in relation to their respective
     holdings in the Company but do not affirm the existence of any such group.
     Each of the C/R Purchasers disclaims beneficial ownership of any shares of
     Common Stock owned by any other C/R Purchaser.

(2)  These numbers may decrease to the extent that Loomis Sayles can no longer
     cause such shares or Warrants to be sold to a C/R Purchaser. See Item 6
     below for a description of the Loomis Securities Purchase Agreement. C/R GP
     is the sole general partner of each of the C/R Purchasers and exercises
     investment discretion and control over the shares of Common Stock and
     Warrants held by each of the C/R Purchasers. Hence, in such capacity, C/R
     GP may be deemed to have the power to dispose or direct the disposition of
     the shares of Common Stock and Warrants that each of the C/R Purchasers
     would hold, and shares of Common Stock which each of the C/R Purchasers
     would hold upon exercise of such Warrants, and to vote or direct the vote
     of such shares of Common Stock. William E. Conway, Jr., Daniel A.
     D'Aniello, David M. Rubenstein, Pierre F. Lapeyre, Jr., David M. Leuschen
     and Jim H. Derryberry, as the sole stockholders of C/R GP, may be deemed to
     share beneficial ownership of the shares shown as beneficially owned by the
     Reporting Persons. Such persons disclaim any such beneficial ownership.

(3)  These numbers may decrease to the extent that Loomis Sayles can no longer
     cause such shares or Warrants to be sold to Nautilus. See Item 6 below for
     a description of the Loomis Securities Purchase Agreement. On July 16,
     2002, Nautilus filed a separate Schedule 13D with respect to the shares of
     Common Stock and Warrants to be purchased by it pursuant to the Securities
     Purchase Agreements, on behalf of itself and its other reporting persons
     (collectively, the "Nautilus Entities"). The Reporting Persons and the
     Nautilus Entities may be deemed to be acting as a group in relation to
     their respective holdings in the Company but do not affirm the existence of
     any such group. Each of the Reporting Persons disclaims beneficial
     ownership of any shares of Common Stock owned by the Nautilus Entities.

         All calculations made herein are made in accordance with Rule 13d-3(d)
under the Exchange Act and based on the 10,623,938 shares of Common Stock
outstanding as of July 3, 2002, as reported by the Company in its preliminary
proxy statement, filed as of July 9, 2002.

               (c) None of the Reporting Persons has effected any transactions
in shares of Common Stock during the past 60 days.


                                       9



         (d) The right to receive dividends on, and proceeds from the sale of,
the shares of Common Stock held of record by the C/R Purchasers and beneficially
owned by their general partner, as described in paragraphs (a) and (b) above, is
governed by the applicable limited partnership agreements of each of such
entities, and such dividends or proceeds may be distributed with respect to
numerous general and limited partnership interests. The limited partner of C/R
Coinvestment II has the right to cause the general partner to distribute all of
the portfolio investments, including the shares of Common Stock and Warrants,
held by C/R Coinvestment II to such limited partner on or after the two-year
anniversary of C/R Coinvestment II's initial acquisition of such shares and
Warrants, subject to any then-applicable legal, tax, regulatory or contractual
restrictions. See Item 6 below for a description of the C/R Coinvestment II
Agreement.

         (e) Not applicable.

Item 6.  Contracts, Arrangements, Understandings or Relationships with Respect
         to Securities of the Issuer.

         Upon the terms and conditions set forth in the Company Stock Purchase
Agreement, the Loomis Securities Purchase Agreement, the Term Sheet for the
Stockholders' Agreement (the "Stockholders' Agreement Term Sheet") and the Fee
Letter (the "Fee Letter") (attached hereto as Exhibit 1, Exhibit 2, Exhibit 3
and Exhibit 4 respectively, and incorporated herein by reference), the C/R
Purchasers and Nautilus will purchase the shares of Common Stock covered by this
statement.

         Company Stock Purchase Agreement

         The following description of the Company Stock Purchase Agreement is a
summary thereof and does not purport to be complete and is qualified in its
entirety by reference to the Company Stock Purchase Agreement.

         Pursuant to the Company Stock Purchase Agreement, the Company has
agreed to sell to the C/R Purchasers and Nautilus, and the C/R Purchasers and
Nautilus have agreed to purchase from the Company, a total of 12,500,000 shares
of Common Stock for a price of $8.00 per share and an aggregate purchase price
of $100,000,000.

         The sale and purchase of the Common Stock (the "Closing") will take
place upon the satisfaction of certain conditions set forth in the Company Stock
Purchase Agreement, including, without limitation, obtaining a ruling from the
United States Coast Guard that, following the transactions contemplated by the
Purchase Agreements, the Company will not fail to meet the requirements of
Section 2 of the Shipping Act, 1916, as amended, for ownership and operation of
vessels in the United States coastwide trade; obtaining the approval of the
stockholders of the Company; and the expiration of applicable waiting periods
under the HSR Act.

         Under the terms of the Company Stock Purchase Agreement, the Company is
obligated to seek and obtain the approval of the holders of the Common Stock at
a meeting of its stockholders (i) to issue the shares of Common Stock to be
purchased by the C/R Purchasers and Nautilus pursuant to the Company Stock
Purchase Agreement, and (ii) to adopt an amendment to the certificate of
incorporation, which amendment, among other things, would increase the number of
authorized shares of Common Stock from 20,000,000 to 40,000,000 and eliminate
the classification of the Company's Board of Directors. Pursuant to the Company
Stock Purchase Agreement, the Board of Directors of the Company is obligated to
recommend such approvals.

         The Company has also agreed to pay the expenses of the C/R Purchasers
and Nautilus incurred since January 1, 2002 in certain circumstances, including
the successful consummation of the transactions contemplated by the Company
Stock Purchase Agreement.

                                       10



         In the event that the transactions contemplated by the Company Stock
Purchase Agreement are not consummated as a result of a breach by the Company of
certain of its obligations thereunder or if the Board of Directors of the
Company accepts an unsolicited proposal by a third party and thereafter
terminates the Company Stock Purchase Agreement, then the Company is obligated
to pay to the C/R Purchasers and Nautilus a termination fee of $6,000,000
collectively. However, the Company will be obligated to pay their expenses only
up to $2,000,000 collectively.

         Upon the Closing, the Company, the C/R Purchasers and Nautilus will
enter into a Stockholders' Agreement on the terms set forth in the Stockholders'
Agreement Term Sheet, which is described below.

         Loomis Securities Purchase Agreement

         The following description of the Loomis Securities Purchase Agreement
is a summary thereof and does not purport to be complete and is qualified in its
entirety by reference to the Loomis Securities Purchase Agreement.

         Pursuant to the Loomis Securities Purchase Agreement, Loomis Sayles has
agreed to Cause (as defined therein) its managed accounts to sell to the C/R
Purchasers and Nautilus, and the C/R Purchasers and Nautilus have agreed to
purchase from such managed accounts, a total of up to 5,256,122 shares of Common
Stock for a price of $8.00 per share; up to 49,915 Class A Common Stock Purchase
Warrants for a price of $0.01 per warrant, with one Class A Common Stock
Purchase Warrant immediately exercisable for one share of Common Stock at an
exercise price of $38.49 and expiring on December 14, 2003; and up to 130,602
Common Stock Purchase Warrants for a price of $7.99 per warrant, with one Common
Stock Purchase Warrant immediately exercisable for one share of Common Stock at
an exercise price of $0.01 and expiring on June 30, 2007 (collectively, the
"Warrants"). It is possible that the deliverable number of shares of Common
Stock and Warrants may be less than the number of shares of Common Stock and
Warrants which the C/R Purchasers and Nautilus are obligated to purchase.

         The sale and purchase of the Common Stock and the Warrants will take
place upon the satisfaction of certain conditions set forth in the Loomis
Securities Purchase Agreement.

         Under the terms of the Loomis Securities Purchase Agreement, Loomis
Sayles is obligated to Cause the shares of Common Stock controlled by it to be
voted in favor of the (i) issuance of the shares of Common Stock to be purchased
by the C/R Purchasers and Nautilus pursuant to the Company Stock Purchase
Agreement, and (ii) the adoption of the amendment to the certificate of
incorporation.

         Stockholders' Agreement Term Sheet

         The following description of the Stockholders' Agreement Term Sheet is
a summary thereof and does not purport to be complete and is qualified in its
entirety by reference to the Stockholders' Agreement Term Sheet.

         The Company Stock Purchase Agreement requires as a condition to the
consummation of the transactions described herein that upon the Closing, the
Company, the C/R Purchasers, Nautilus and a management stockholder enter into a
Stockholders' Agreement (the "Stockholders' Agreement") based on the terms set
forth in the Stockholders' Agreement Term Sheet. Under the terms of the
Stockholders' Agreement Term Sheet, the Stockholders' Agreement will provide the
C/R Purchasers and Nautilus with the following rights, among others: (i)
representation on the Company's Board of Directors, specifically, two directors
to be designated by certain of the C/R Purchasers and four directors to be
designated by Nautilus; (ii) demand registration rights; (iii) piggyback
registration rights; (iv) rights of first refusal in connection with any
proposed transfer of Common Stock to a third party by the other parties to the
Stockholders' Agreement; (v) tag-along rights to participate in sales of common
stock by the other parties to the Stockholders' Agreement; and (vi) preemptive
rights to purchase their pro rata portion of new securities issued by the
Company. Transfers of shares of Common Stock held by the parties to the

                                       11



Stockholders' Agreement will be restricted. The Stockholders' Agreement
will provide that the Company may not grant additional registration rights to
any other person or entity and will cause all registration rights agreements to
which it is currently a party to be terminated.

         Fee Letter

         The following description of the Fee Letter is a summary thereof and
does not purport to be complete and is qualified in its entirety by reference to
the Fee Letter.

         Upon the Closing, the Company shall pay a fee to Carlyle/Riverstone
Energy Partners, L.P., an affiliate of the Reporting Entities, in an amount of
$1,000,000. Upon the Closing, the Company shall pay a fee to Credit Suisse First
Boston Corporation, Inc., an affiliate of Nautilus, in an amount of $2,000,000.

         Except for the agreements described above or in the response to Item 4,
to the best knowledge of the Reporting Persons, there are no contracts,
arrangements, understandings or relationships (legal or otherwise) among the
persons named in Item 2 and between such persons and any person with respect to
any securities of the Company, including, but not limited to, transfer or voting
of any of the securities, finder's fees, joint ventures, loan or option
arrangements, puts or calls, guarantees of profits, division of profits or loss,
or the giving or withholding of proxies.

         C/R Coinvestment II Agreement

         The following description of the letter agreement, dated as of July 16,
2002, by and between C/R GP and Midstream Holdings, LLC, with respect to C/R
Coinvestment II (the "C/R Coinvestment II Agreement," which is attached hereto
as Exhibit 5 and incorporated herein by reference), is a summary thereof and
does not purport to be complete and is qualified in its entirety by reference to
the C/R Coinvestment II Agreement.

         Pursuant to the C/R Coinvestment II Agreement, the limited partner of
C/R Coinvestment II will have the right to cause C/R Coinvestment II to
distribute all of the portfolio investments, including any shares of Common
Stock and Warrants, held by C/R Coinvestment II to such limited partner on or
after the two-year anniversary of C/R Coinvestment II's initial acquisition of
such shares and Warrants, subject to any then-applicable legal, tax, regulatory
or contractual restrictions. Subsequently, such shares of Common Stock and
Warrants will be subject to the terms and conditions of the Shareholders'
Agreement. Until such shares and Warrants are distributed to such limited
partner, it will have the right to participate, through C/R Coinvestment II, in
any further transactions engaged in by the C/R Purchasers in respect of the
Company on a pro rata basis with the other C/R Purchasers.

         Management and control over C/R Coinvestment II, including with respect
to its investments, will be vested solely in C/R GP, as the general partner.
