ITEM 9. REGULATION FD DISCLOSURE.

         On August 14, 2002, Lee Ann Anderson, Vice President of Bank One, N.A.
(the "Trustee") of the San Juan Basin Royalty Trust (the "Trust"), submitted a
certification to the Securities and Exchange Commission, relating to the Trust's
Quarterly Report on Form 10-Q for the quarter ended June 30, 2002, pursuant to
18 U.S.C. Section 1350, adopted pursuant to the Sarbanes-Oxley Act of 2002. The
certification was submitted by a Vice President of the Trustee of the Trust as
the Trust has no executive officers.

         The text of the Certification was as follows:

              "In connection with the accompanying report on Form 10-Q for the
              period ending June 30, 2002, and filed with the Securities and
              Exchange Commission on the date hereof (the "Report"), I, Lee Ann
              Anderson, Vice President of Bank One, N.A., the Trustee of the San
              Juan Basin Royalty Trust (the "Trust"), hereby certify that:

                  1.  The Report fully complies with the requirements of Section
                      13(a) or 15(d) of the Securities Exchange Act of 1934 (as
                      explained in Note 1 to the Trust's financial statements
                      contained in the Report, the Trust continues to prepare
                      its financial statements in a manner that differs from
                      generally accepted accounting principals; such
                      presentation is customary to other royalty trusts); and

                  2.  The information contained in the Report fairly presents,
                      in all material respects, the financial condition and
                      results of operations of the Trust."

in this report is furnished pursuant to Item 9 and shall not be deemed to be
"filed" for the purposes of Section 18 of the Securities Exchange Act of 1934,
