Item 3.

Source and Amount of Funds or Other Consideration

In connection with entering into the Agreement and Plan of Merger, dated as of April 6, 2004, among Kerr-McGee, Kerr-McGee (Nevada) LLC (“Merger Sub”) and Westport (the “Merger Agreement”), Kerr-McGee entered into Voting Agreements, dated as of April 6, 2004 (the “Voting Agreements”), with certain stockholders of Westport named therein (the “Westport Principal Stockholders”), pursuant to which, among other things, each Westport Principal Stockholder, severally and not jointly, has agreed to vote the shares of Westport Common Stock held by such stockholder in favor of the Merger Agreement and has granted Kerr-McGee an irrevocable proxy coupled with an interest to vote such shares of Westport Common Stock in favor of the Merger Agreement.  As a result, Kerr-McGee may be deemed to be the beneficial owner of 28,670,633 shares of Westport Common Stock.  See the response to Item 5.

The descriptions of the Merger Agreement and the Voting Agreements contained herein are qualified in their entirety by reference to such agreements, which are attached hereto as Exhibits 1-6.

Item 4.

Purpose of Transaction

The Voting Agreements were entered into as a condition to the willingness of Kerr-McGee to enter into the Merger Agreement and to facilitate the approval of Westport's stockholders required in connection with the merger of Westport with and into Merger Sub (the “Merger”).  In the Merger, Merger Sub will continue as the surviving enitity and will become a wholly owned subsidiary of Kerr-McGee.

In addition to providing for the Merger, the Merger Agreement restricts Westport from, among other things, engaging in certain transactions, including extraordinary corporate transactions (other than the Merger), selling certain assets, changing its capitalization (including by purchasing any of its capital stock or by issuing any capital stock or other voting securities), amending its articles of incorporation or by-laws, paying dividends, incurring indebtedness, making loans or advances to other persons, making certain acquisitions and making certain capital expenditures, and otherwise requires Westport to operate in the ordinary course of business.  The restrictions described in this paragraph are subject to certain exceptions.

Pursuant to the Merger Agreement, the managers of Merger Sub immediately prior to the effective time of the Merger will be the managers of the surviving entity following the Merger.

In connection with the Merger, it is expected that Westport Common Stock will be delisted from the New York Stock Exchange and will become eligible for termination of registration under the Securities Exchange Act of 1934, as amended.

The descriptions of the Merger Agreement and the Voting Agreements contained herein are qualified in their entirety by reference to such agreements, which are attached hereto as Exhibits 1-6.

Item 5.

Interest in Securities of the Issuer

As a result of the Voting Agreements, Kerr-McGee may be deemed to be the beneficial owner of 28,670,633 shares of Westport Common Stock, which would represent approximately 42.2% of Westport Common Stock (based on the number of shares outstanding as of April 6, 2004, as set forth in the Merger Agreement).

Under the terms of the Voting Agreements, each Westport Principal Stockholder has agreed, among other things, to vote (i) in favor of the Merger and the adoption of the Merger Agreement and the approval of the other transactions contemplated thereby, and any actions required in furtherance thereof; (ii) against any action or agreement that such stockholder would reasonably expect to result in a breach in any material respect of any covenant, representation or warranty or any other obligation of Westport under the Merger Agreement; and (iii) against (A) any extraordinary corporate transaction, such as a merger, rights offering, reorganization, recapitalization or liquidation involving Westport or any of its subsidiaries (other than the Merger), (B) a sale or transfer of a material amount of assets or capital stock of Westport or any of its subsidiaries or (C) any action that is intended, or would reasonably be expected, to prevent or materially delay or otherwise interfere with the Merger and the other transactions contemplated by the Merger Agreement.  Accordingly, pursuant to the Voting Agreements, Kerr-McGee may be deemed to have acquired shared voting power with respect to the Westport Common Stock subject to the Voting Agreements.

To the best of Kerr-McGee’s knowledge, no shares of Westport Common Stock are beneficially owned by any of the persons named in Attachment A. Neither Kerr McGee nor, to the best knowledge of Kerr-McGee, any person named in Attachment A, has effected any transaction in the Westport Common Stock during the past 60 days.

The descriptions of the Merger Agreement and the Voting Agreements contained herein are qualified in their entirety by reference to such agreements, which are attached hereto as Exhibits 1-6.
