Kaiser Aluminum Reports on Results of Court Hearing.

Business Editors

HOUSTON--(BUSINESS WIRE)--Feb. 4, 2004

Kaiser Aluminum announced that, in a special hearing on February 2, the U.S. Bankruptcy Court for the District of Delaware conditionally approved the company's previously announced agreement in principle with the United Steelworkers of America (USWA), and the recently concluded agreements in principle with the 1114 Committee, which represents salaried retirees, and the International Association of Machinists (IAM), which represents hourly employees at two Kaiser locations, regarding certain pension and post-retirement benefits. The USWA and the IAM represent the vast majority of the company's U.S. hourly employees.

The agreements in principle are subject to various approvals, including ratification by union members, approval by the company's Board of Directors, and final approval by the Bankruptcy Court. The agreements are also conditioned upon the satisfactory resolution of certain intercompany claims.

Separately, the company continues to have discussions with four additional unions concerning pension and post-retirement benefits.

The agreements in principle conditionally approved by the Court provide for:

-- The termination of existing post-retirement benefit programs

-- such as retiree medical -- for current and future retirees

who are or were salaried employees, members of the USWA, and

members of the IAM (as well as surviving spouses and

dependents). Under the agreements in principle, these

participants would be provided an opportunity for continued

retiree medical coverage through COBRA or a proposed Voluntary

Employee Beneficiary Association (VEBA). As previously

disclosed, Kaiser would fund the VEBA with a combination of

cash, profit-sharing, and other consideration, subject to

certain caps and limits.

-- The termination of existing pension plans for current and

future retirees represented by the USWA and IAM. Under the

agreements in principle, active employees who are represented

by the USWA and the IAM would be provided with an opportunity

to participate in one or more replacement pension plans and/or

defined contribution plans. The Court's conditional approval

of this agreement in principle came in conjunction with a

ruling that Kaiser has satisfied the criteria for distress

termination of its U.S. hourly pension plans. Vested benefits 

under defined benefit pension plans are guaranteed by the

PBGC, up to certain limits.

After all required approvals -- including final Court approval -- are obtained in connection with the agreements in principle, the company will advise participants of the termination dates for the post-retirement and pension benefit programs.

On a related matter, as previously reported, the pension plan for salaried employees was terminated by the Pension Benefit Guaranty Corporation on December 17, 2003. Kaiser expects that current salaried employees will be provided with an opportunity to participate in a replacement plan.

"These agreements in principle represent the best efforts of Kaiser and the other stakeholders to address this unfortunate situation and to provide employees and retirees with some level of ongoing coverage while at the same time helping Kaiser to advance toward a planned emergence from Chapter 11 at mid year," said Jack A. Hockema, president and chief executive officer.
