NOW, THEREFORE, the parties to this Agreement, intending to be legally bound, hereby covenant and agree as follows: 1. No Transfer or Disposition of Shares. Unless the Company's Board of Directors ("Board") has terminated the Common Stock transfer restrictions set forth in Article XIII of the Company's Amended and Restated Certificate of Incorporation ("Certificate"), each of AL-CH, the UAW Trust and the Non-UAW Trust covenant and agree that, during the period commencing on the date hereof and continuing until the third (3rd) anniversary of the Release Event Date, it will not, directly or indirectly, sell, transfer, assign or otherwise dispose any shares of Common Stock now beneficially owned. Nothing provided in this Agreement shall restrict AL-CH, the UAW Trust or the Non-UAW Trust from distributing to any partner or beneficiary, respectively, shares of Common Stock as long as such partner or beneficiary, as the case may be, executes and delivers a lock-up agreement containing provisions substantially similar to the provisions of this Section. 2. Prior Opportunity to Sell. (a) Each of AL-CH, the UAW Trust and the Non-UAW Trust covenant and agree that, during the period (the "Window Period") commencing with the third (3rd) anniversary of the Release Event Date and continuing until the fifth (5th) anniversary of the Release Event Date, it will not, directly or indirectly, sell, transfer, assign or otherwise dispose of any shares of Common Stock without first giving the PBGC an opportunity to sell all or any portion of the shares of Common Stock it now beneficially owns pursuant to (b) or (c) below. (b) If AL-CH, the UAW Trust or the Non-UAW Trust desire to sell shares of Common Stock during the Window Period in a public offering pursuant to an effective registration statement under the Securities Act of 1933, as amended, it shall first give written notice to the PBGC of such intention not less than twenty (20) business days prior to effecting any sale. If the PBGC, by written notice to all of the other parties to this Agreement given within twenty (20) business days after the receipt of such notice of intention to sell, elects to sell shares of Common Stock, then AL-CH, the UAW Trust and the Non-UAW Trust shall refrain from effecting any sale until the earlier of (i) forty-five (45) days after receipt of written notice from the PBGC indicating its desire to sell its shares or (ii) the fifth (5th) anniversary of the Release Event Date. The PBGC covenants and agrees that, if it elects to sell shares of Common Stock during the Window Period prior to sales by AL-CH, the UAW Trust and the Non-UAW Trust, that it will diligently pursue the sale of such shares, subject in all cases to market conditions, and that it will notify all of the other parties to this Agreement in writing at any time that the PBGC has completed or discontinued its proposed sale of shares of Common Stock. (c) If any time AL-CH, the UAW Trust or the Non-UAW Trust is presented with an opportunity to sell shares of Common Stock during the Window Period other than in a public offering, AL-CH, the UAW Trust or the Non-UAW Trust, as the case may be, shall first give written notice to the PBGC and all of the other parties to this Agreement of such opportunity (including the proposed sale price and other material terms and conditions) not less than twenty (20) business days prior to effecting any sale. If the PBGC, by written notice to all of the parties to this Agreement given within twenty (20) business days after the receipt of such notice of intention to sell, elects to sell shares of Common Stock in such transaction, then the PBGC shall have the right, until the earlier of (i) forty-five (45) days after delivery of the written notice from the PBGC indicating its desire to sell shares or (ii) the fifth (5th) anniversary of the Release Event Date, to sell shares of Common Stock pursuant to such opportunity. If the PBGC has not consummated a sale of shares of Common Stock during such time period, then AL-CH, the UAW Trust or the Non-UAW Trust, as the case may be, shall be entitled to sell shares of Common Stock upon terms no less favorable than those offered to the PBGC. (d) Nothing provided in this Agreement shall limit or restrict in any way the Company's right of refusal set forth in Section 4.6 of the Master Agreement. -2- 3. Voting. During the term of this Agreement, each party covenants and agrees to vote, at any annual or special meeting of the Company stockholders and in a written consent, all shares of Common Stock beneficially owned in favor of the election as director the persons nominated for director of the Company by the Nominating Committee of the Company's Board of Directors, and to refrain from taking any action contrary to or inconsistent with such obligation. During the term of this Agreement, each party further covenants and agrees not to vote its shares of Common Stock or to take any other action to amend the Company's Certificate or By-laws in a manner that is inconsistent with, or in breach of, the Master Agreement. Without limiting the generality of the foregoing, each party hereto agrees that it will (i) vote all of its Common Stock in favor of the amendments to the Company's Certificate identified on the attached Exhibit A, (ii) vote all of its Common Stock for the election of the persons designated by the PBGC (each, a "PBGC Director") to serve on the Board of Directors of the Company and (iii) vote all of its Common Stock in favor of the election of Company directors who are committed to cause, and who do cause, one (1) PBGC Director to be appointed to the Nominating Committee of the Company's Board of Directors ("Board"), and one (1) PBGC Director to be appointed as the Chairman of the Compensation Committee of the Board. 4. Representations and Warranties. Each of AL-CH, the UAW Trust and the Non-UAW Trust hereby severally represents and warrants to the PBGC as follows (it being understood and agreed that no such party, including but not limited to AL-CH, is making any representations or warranties on behalf of any other party): (a) Each is duly organized and validly existing, and has all requisite power and authority to conduct its business as it is now being conducted.

The captions used in this Agreement are for purposes of convenience only and shall not be deemed to modify, or provide any basis for interpretation of, any of the provisions of this Agreement. 5.9 Governing Law. The Agreement shall be construed in accordance with, and shall be governed by, the internal laws of the State of Delaware. 5.10 Jurisdiction. The courts of the State of New York in New York County and the United States District Court for the Southern District of New York shall have jurisdiction over the parties with respect to any dispute or controversy between them arising under or in connection with this agreement and, by execution and delivery of this agreement, each of the parties to this Agreement submits to the jurisdiction of those courts, including but not limited to the in personam and subject matter jurisdiction of those courts, waived any objections to such jurisdiction on the grounds of venue or forum non conveniens, the absence of in personam or subject matter jurisdiction and any similar grounds, consents to service of process by mail (in accordance with Section 5.2) or any other manner permitted by law, and -6- irrevocably agrees to be bound by any judgment rendered thereby in connection with this Agreement. 5.11 Mutual Waiver of Jury Trial. Because disputes arising in connection with complex financial transactions are most quickly and economically resolved by an experiences and expert person and the parties wish applicable state and federal laws to apply (rather than arbitration rules), the parties desire that their disputes be resolved by a judge applying such applicable laws. Therefore, to achieve the best combination of the benefits of the judicial system and of arbitration, the parties hereto waive all right to trial by jury in any action, suit or proceeding brought to enforce or defend any rights of remedies under this Agreement. 5.12 Term. This Agreement shall continue in effect until the earlier of (i) the fifth (5th) anniversary of the Release Event Date or (ii) such time as the PBGC ceases to beneficially own not less than 117,020 shares of Common Stock (subject to adjustment as provided in Section 5.13 hereof). 5.13 Equitable Adjustment. In the event of a stock split, reverse stock split, recapitalization, reorganization or comparable change in the Company's capital structure (other than an issuance of Common Stock for fair value), any reference to a specific number of shares of Common Stock herein shall be equitably adjusted to reflect such change. IN WITNESS WHEREOF, the parties have executed this Agreement as of the date first above written. ALLIS-CHALMERS CORPORATION By: /s/John T. Grigsby, Jr. Name: John T.
