Exhibit 10(o)(A)

                          UNITED STATES DISTRICT COURT
                      FOR THE EASTERN DISTRICT OF WISCONSIN

UNITED STATES OF AMERICA
and the STATE OF WISCONSIN
                                               CIVIL ACTION NO. 03-C-0949

             Plaintiffs,

                  v.

                                               The Honorable Lynn Adelman

P. H. GLATFELTER COMPANY
and
WTM I COMPANY
(f/k/a Wisconsin Tissue Mills Inc.),

             Defendants.

                       AGREED SUPPLEMENT TO CONSENT DECREE

     The Plaintiffs and Defendants in this action have entered into this Agreed
Supplement to Consent Decree (the "Agreed Supplement") in order to memorialize
an agreement reached in accordance with Subparagraph 98.d of the existing
Consent Decree. As explained below, this Agreed Supplement sets forth the
Defendants' agreement to commit additional funds for performance of their
obligations under the Consent Decree, as envisioned by Decree Subparagraph 98.d.
The United States is filing this Agreed Supplement with the Court to make it
part of the public record concerning the Consent Decree, but the Court need not
take any action on this filing.

     1. The Plaintiffs filed this action on October 1, 2003, alleging that the
Defendants are among the parties liable for environmental contamination at the
Lower Fox River and Green Bay Site (the "Site") pursuant to the Comprehensive
Environmental Response, Compensation, and Liability Act, 42 U.S.C. Sections
9601-9675. At the same time, the United States lodged with the



Court a proposed Consent Decree between the Plaintiffs and Defendants. After a
public comment period, the Court approved and entered the Consent Decree in a
Decision and Order dated April 12, 2004.

     2. The Consent Decree requires the Defendants to perform sediment
remediation work at the portion of the Site that has been designated as Operable
Unit 1 ("OU1"). The Defendants began remedial work, including removing sediment
from OU1, in 2004, and the active remediation phase of that response work has
not yet been completed. The work is being overseen by the U.S. Environmental
Protection Agency ("EPA") and the Wisconsin Department of Natural Resources
("WDNR").

     3. The Defendants are paying for the response work that they are performing
in OU1 using funds deposited in a dedicated escrow account established under the
Consent Decree (the "Escrow Account"). If EPA, in consultation with WDNR,
determines at any time that the funds remaining in that Escrow Account are not
sufficient to finance the completion of the response work, EPA has certain
rights that can lead to termination of the Consent Decree. As an alternative to
that course of action, Consent Decree Subparagraph 98.d affords the Defendants
an opportunity to "deposit additional funds in the Escrow Account, in order to
avoid an Insufficiency Determination."

     4. The Plaintiffs recently notified the Defendants that EPA was considering
making a formal finding that the fund balance remaining in Escrow Account was
likely to be insufficient to fund the completion of the response work. The
parties have agreed to address that potential shortfall in the Escrow Account as
set forth in the following Paragraph.


                                        2



     5. In accordance with Consent Decree Subparagraph 98.d, the parties hereby
agree that the Defendants shall deposit additional funds in the Escrow Account
established under the Consent Decree, as follows:

          a. Defendant WTM I Company ("WTM I") shall deposit an additional $6
     million in the Escrow Account. That total amount shall be paid in three
     equal installments: (i) $2 million shall be payable on or before April 10,
     2007; (ii) an additional $2 million shall be payable on or before July 10,
     2007; and (iii) the final $2 million shall be payable on or before January
     10, 2008. All three payments shall be deposited in a separate sub-account
     within the Escrow Account (the "WTM I Sub-account"), so that those funds
     can be distinguished from the other funds in the Escrow Account (the
     "Existing Funds").

          b. By no later than April 10, 2007, Defendant P.H. Glatfelter Company
     ("Glatfelter") shall obtain a $6 million irrevocable letter of credit
     payable to the Escrow Account. The irrevocable letter of credit shall be
     issued by a financial institution that has the authority to issue letters
     of credit and whose letter of credit operations are regulated and examined
     by an agency of the United States Government. The financial institution
     shall have surplus and reserves in excess of $500 million. The irrevocable
     letter of credit shall identify EPA as the beneficiary and the full $6
     million shall immediately be payable to the Escrow Account: (i) at any time
     before April 10, 2008, upon EPA's written certification that the Existing
     Funds balance in the Escrow Account is below $2 million (by a letter in the
     form attached hereto as Exhibit A); or (ii) on April 10, 2008, if payment
     has not already been made by that date. The payment under the irrevocable
     letter of credit shall be deposited in a separate sub-account within the
     Escrow Account (the


                                        3



     "Glatfelter Sub-account"), so that those funds can be distinguished from
     the Existing Funds. At least five business days before finalizing the
     letter of credit, Glatfelter shall afford the Plaintiffs and WTM I an
     opportunity to review the proposed letter of credit to assess whether it
     conforms to the requirements of this Subparagraph. Notwithstanding the
     requirement that the letter of credit be irrevocable, at any time prior to
     payment under the irrevocable letter of credit, Glatfelter may deposit $6
     million into the Glatfelter Sub-account," at which time, Glatfelter may
     cancel the letter of credit.

          c. The Defendants shall direct the Escrow Account manager as follows:
     All Existing Funds shall be exhausted before disbursement of any amounts
     from the separate sub-accounts established and funded under the preceding
     Subparagraphs of this Agreed Supplement. After the Existing Funds are
     exhausted, the WTM I and Glatfelter Sub-accounts shall each be drawn upon
     in equal amounts, on a 50/50 basis, to pay for response work.

          d. The parties hereby agree that the additional funds to be paid into
     the Escrow Account under the preceding Subparagraphs of this Agreed
     Supplement fall within the definition of the "OU1 Response Activities and
     Costs" specified by Consent Decree Subparagraph 83.b.

     6. Pursuant to Consent Decree Section XXX (Retention of Jurisdiction), the
Court has jurisdiction to enforce compliance with the terms of this Agreed
Supplement because the Court retained jurisdiction over both the subject matter
of the Consent Decree and the Settling Defendants for the duration of the
performance of the terms and provisions of the Consent Decree for the purpose of
enabling any of the parties to apply to the Court at any time for such further
order, direction, and relief as may be necessary or appropriate for the
construction or


                                        4



modification of the Consent Decree, or to effectuate or enforce compliance with
its terms, or to resolve disputes in accordance with Consent Decree Section XX
(Dispute Resolution).

     IT IS SO STIPULATED AND AGREED.
