RE:         Election to extend term of Partnerships for additional
            two years


      On November  21,  2003,  we mailed you a letter  stating  that the limited
partnership  agreements,  as amended (the "Agreements") for the above referenced
Geodyne Energy Income Limited Partnerships (the "Partnerships") provide that the
Partnerships will automatically terminate and dissolve on December 31, 2003, and
that the  Agreements  give  Geodyne  Resources  as General  Partner an option to
extend the terms of the Partnerships for up to five additional two year terms.

      The letter further  stated that Geodyne had exercised two such  extentions
and  notified  you that it had elected to extend the  Partnerships'  terms for a
third,  additional two year period. This information was not correct.  Two years
ago Geodyne exercised the first such extensions. Geodyne is hereby notifying you
that it has elected to extend the Partnerships'  terms for a second,  additional
two year period. Accordingly,  Geodyne will file amendments to the Partnerships'
Certificates  of Limited  Partnership  extending the  Partnerships'  terms until
December 31, 2005.

If you  have any  questions  concerning  the  Partnerships'  extensions,  please
contact Geodyne Investor Services at 918-583-1791 or 888-436-3963.

                                    Very truly yours,
