Exhibit 99.1

Statement Under Oath of Principal Executive Officer and Principal Financial
Officer Regarding Facts and Circumstances Relating to Exchange Act Filings

I, John T. Dillon, state and attest that:

     (1) To the best of my knowledge, based upon a review of the covered reports
of International Paper Company, and, except as corrected or supplemented in a
subsequent covered report:

     o   no covered report contained an untrue statement of a material fact as
         of the end of the period covered by such report (or in the case of a
         report on Form 8-K or definitive proxy materials, as of the date on
         which it was filed); and

     o   no covered report omitted to state a material fact necessary to make
         the statements in the covered report, in light of the circumstances
         under which they were made, not misleading as of the end of the period
         covered by such report (or in the case of a report on Form 8-K or
         definitive proxy materials, as of the date on which it was filed).

     (2) I have reviewed the contents of this statement with the Company's Audit
         and Finance Committee.

     (3) In this statement under oath, each of the following, if filed on or
         before the date of this statement, is a "covered report":

     o   International Paper Company's Annual Report on Form 10-K for the fiscal
         year ended December 31, 2001;

     o   all reports on Form 10-Q, all reports on Form 8-K and all definitive
         proxy materials of International Paper Company filed with the
         Commission subsequent to the filing of the Form 10-K identified above;
         and

     o   any amendments to any of the foregoing.

                                          /s/ John T. Dillon
                                          ------------------
