Exhibit Number		Description of Exhibit
99.1		Press Release dated June 15, 2007.

~~The~~SIGNATURES ~~Agreement:~~

The Agreement contemplates transactions by which the Company and Esmark will become wholly owned subsidiaries of the new holding company, New Esmark. Subject to the terms and conditions of the Agreement WPC Merger Sub will merge with and into the Company (the “WPC Merger”). Simultaneous with the WPC Merger, Esmark Merger Sub will merge with and into Esmark (the “Esmark Merger”). Upon or prior to consummation of the combination, New Esmark will be renamed “Esmark Incorporated” and Esmark will be renamed “Esmark Steel Service Group, Inc.”

The WPC Merger will result in each issued and outstanding share of common stock of the Company being converted into a right to receive one share of common stock of New Esmark. In addition to that share for share exchange option, the Company’s stockholders may elect to receive a share of common stock of New Esmark plus (1) a put right allowing the stockholder to put back to New Esmark within a ten day period each of the shares of New Esmark that were issued to such stockholder in the exchange for $20.00 per share, subject to a maximum of $150.0 million being paid for all exercised put elections, or (2) a right to purchase, within a ten day period, one additional share of New Esmark common stock at $19.00

per share for each share of the Company’s stock that was exchanged by such stockholder, subject to a maximum of $200.0 million worth of New Esmark common stock (at such $19.00 price) being purchased under the purchase rights. Both the put and rights elections are subject to proration if the elections exceed the specified amounts.

As a condition to the closing of the Agreement, those funds managed by Franklin Mutual Advisers, LLC that are stockholders of Esmark (collectively, “Franklin”) and the Company are required to enter into a standby purchase agreement (the “Standby Agreement”) that will require Franklin to purchase any of the foregoing unexercised purchase rights (up to a maximum of $200.0 million) and that, in any event, will obligate the Company to provide Franklin a minimum of $50.0 million in purchase rights. In each case, Franklin’s purchase rights would be exercisable at a $19.00 per share price.

As a result of the Esmark Merger and in exchange for all of the issued and outstanding shares of Esmark stock, Esmark stockholders would receive 17.5 million shares of New Esmark common stock in the aggregate, plus additional shares of New Esmark common stock for any new equity raised by Esmark prior to May 15, 2007 (the “Additional Esmark Equity”).

Upon the effective time of the combination, the directors of New Esmark shall be comprised of thirteen directors, consisting of all eleven directors of the Company as of the date of the Agreement and two designees of Esmark. James P. Bouchard will be the Chairman of the Board and Chief Executive Officer of New Esmark and Craig T. Bouchard will be the Vice Chairman of the Board and President of New Esmark.

The Company has made customary representations and warranties and covenants in the Agreement, including, among others, covenants:

• governing the conduct of business by the Company pending the closing of the transactions contemplated by the Agreement; • not to solicit takeover proposals or, subject to certain exceptions, furnish information to or enter into discussions or negotiations with third parties regarding takeover proposals; • subject to certain exceptions, for the Company’s Board of Directors to recommend that the Company stockholders adopt the Agreement; and • to cause a meeting of the Company’s stockholders to be held to consider the approval of the Agreement.

Esmark has made customary representations and warranties and covenants in the Agreement, including, among others, covenants:

• governing the conduct of business by Esmark pending the closing of the transactions contemplated by the Agreement; • that the Additional Esmark Equity shall not exceed $100 million without the consent of the Company acting though the Special Committee; • for Esmark’s Board of Directors to recommend that Esmark’s stockholders approve and adopt the Agreement; and • to submit the Agreement to the Esmark’s stockholders for approval.

Closing on the transactions called for in the Agreement is conditioned on, among other customary conditions:

• the accuracy of the representations and warranties (subject generally to a material adverse effect standard); • the adoption of the Agreement by the stockholders of the Company and the stockholders of Esmark; • expiration or early termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended; • shares of New Esmark common stock being approved for listing on The New York Stock Exchange or The NASDAQ Stock Market;

• the agreement by the Company and Esmark on the amount of any Additional Esmark Equity; • the net working capital of Esmark must equal or exceed $100 million plus the amount of any Additional Esmark Equity; and • the execution of the Standby Agreement as well as a registration rights agreement with Franklin regarding any shares of New Esmark purchased pursuant to the Standby Agreement.

The Agreement also contains provisions that provide for its termination in certain circumstances. In the event the Company terminates the Agreement pursuant to a superior proposal received from a third party, the Company has agreed to pay Esmark’s expenses (up to $2 million in the aggregate), and upon termination of the Agreement for any reason, the Company has agreed to reimburse, to the extent that it has not already done so, Esmark for all of Esmark’s fees and expenses in connection with the proxy solicitation for the Company’s 2006 annual meeting (as long as such reimbursement is permitted under Delaware law and the reimbursement amount will not exceed the amount of such fees and expenses which were presented to the Special Committee or which are otherwise agreed to in writing by the Special Committee).

A copy of the Agreement is attached hereto as Exhibit 2.1 and is incorporated herein by reference. The foregoing description does not purport to be complete and is qualified in its entirety by reference to the full text of the Agreement.

In connection with the Agreement, the Company and New Esmark expect to file with the Securities and Exchange Commission (the “SEC”) a registration statement containing a preliminary proxy statement and prospectus. The Company urges its stockholders to read the proxy statement and prospectus in its entirety when it becomes available because it will contain important information regarding the transactions called for in the Agreement.

When filed, the proxy statement and prospectus will be available at no charge at the SEC’s website at http://www.sec.gov.
