The C/R Purchasers, Nautilus Acquisition, L.P., a Delaware limited partnership ("Nautilus") and the Company have entered into a Stock Purchase Agreement, dated as of June 13, 2002 (the "Company Stock Purchase Agreement"), which provides that the C/R Purchasers and Nautilus, subject to certain closing conditions contained therein, will purchase 4,166,667 and 8,333,333 shares, respectively, of Common Stock for a purchase price of $33,333,336 and $66,666,664, respectively. Additionally, the C/R Purchasers, Nautilus and Loomis, Sayles & Company, L.P., a Delaware limited partnership ("Loomis Sayles") have entered into a Securities Purchase Agreement, dated as of June 13, 2002 (the "Loomis Securities Purchase Agreement" and, together with the Company Stock Purchase Agreement, the "Purchase Agreements"), which provides that the C/R Purchasers and Nautilus, subject to certain closing conditions contained therein, will purchase (i) up to 1,752,041 and 3,504,081 shares, respectively, of Common Stock for a purchase price of $14,016,328 and $28,032,648, respectively, and (ii) Warrants to purchase up to 60,172 and 120,345 shares, respectively, of Common Stock, for a purchase price of $348,003.04 and $696,006.09, respectively. 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: Number of Shares of Total Number of % of Equity Common Stock Shares of Common Ownership Number of Issuable Stock (Assuming (Assuming Shares of Upon Exercise of Exercise of Exercise of Name Common Stock Warrants Warrants) Warrants) C/R U.S.(1) ................. 1,204,051 12,241 1,216,292 5.2% C/R Int'l(1) ................ 3,711,670 37,735 3,749,405 16.1% C/R Coinvestment(1) ......... 506,635 5,150 511,785 2.2% C/R Coinvestment II(1) ...... 496,352 5,046 501,398 2.2% C/R GP(2) ................... 5,918,708 60,172 5,978,880 25.7% Nautilus(3) ................. 11,837,414 120,345 11,957,759 51.3% --------- (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.

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. Item 7. Material to be Filed as Exhibits.
