          SPINNAKER ROYALTY COMPANY, L.P. AND DORCHESTER MINERALS, L.P.
                      ANNOUNCE PROXY/PROSPECTUS SUPPLEMENT
                    AND ANTICIPATED COMBINATION CLOSING DATE


     DALLAS,  TEXAS - January  24, 2003 --  Dorchester  Hugoton,  Ltd.  (Nasdaq:
DHULZ), Republic Royalty Company, Spinnaker Royalty Company, L.P. and Dorchester
Minerals, L.P. announced today the filing of Dorchester Minerals' Supplement No.
2 to Proxy Statement/Prospectus Dated October 30, 2002 and the filing of related
Current Reports on Form 8-K by Dorchester Hugoton and Dorchester  Minerals.  The
Supplement and Current Reports relate to the proposed  combination of Dorchester
Hugoton,  Spinnaker  Royalty Company,  L.P. and Republic Royalty Company to form
Dorchester Minerals.

     Upon final  approval of the  combination by more than 50% of the depositary
receipt holders of Dorchester  Hugoton,  all of the limited partners of Republic
and  limited  partners  of  Spinnaker  holding at least  85.9883% of the sharing
percentages of Spinnaker,  and if all other  conditions to the combination  have
been satisfied,  it is anticipated  that the combination  will close January 31,
2003.

     As previously announced,  the adjourned special meeting of limited partners
of Dorchester  Hugoton to consider the  combination  will be reconvened at 10:00
a.m.,  January 29, 2003 at the Holiday Inn,  11350 LBJ Freeway at Jupiter  Road,
Dallas,  Texas  75238.  The  adjourned  special  meeting of limited  partners of
Spinnaker to consider the combination will be reconvened at the same location at
11:00 a.m., January 29, 2003.

     The  Supplement  contains  important  information  concerning  the proposed
combination  of Dorchester  Hugoton,  Republic,  and Spinnaker  into  Dorchester
Minerals,  L.P.,  a new  publicly  traded  limited  partnership.  As  previously
announced, the Supplement contains modifications with respect to enhanced rights
of Dorchester Minerals' common unit holders,  further restrictions on Dorchester
Minerals' general partner in the areas of partnership governance and acquisition
opportunities, registration rights for the Republic ORRI owners and avoidance of
unrelated  business  taxable  income.  The  Supplement  is being mailed today to
depositary  receipt  holders of  Dorchester  Hugoton,  the  limited  partners of
Spinnaker and the Republic ORRI owners as of the respective record dates for the
special meeting.

     The  modifications  are also  described in the Current  Reports on Form 8-K
filed by Dorchester Minerals and Dorchester Hugoton dated January 24,  2003. The
Supplement  and the Current  Reports  will be  available  on the Internet at the
Securities and Exchange Commission's worldwide website at http://www.sec.gov.

     The  respective  general  partners  of  Dorchester  Hugoton,  Republic  and
Spinnaker  believe  that  such  modifications  will  not  adversely  affect  the
fundamental  economic  terms of the  combination  for the  limited  partners  of
Dorchester  Hugoton or  Spinnaker  or for the  Republic  ORRI owners and will be
generally  favorable to common unit holders of  Dorchester  Minerals.  The total
number of Dorchester  Minerals  common units to be issued in the combination and
the number of common units allocated to each  partnership  will remain the same.
As a result of these changes,  the number of common units of Dorchester Minerals
allocated to Republic will be allocated  differently  among the general partners
of Republic and the Republic  ORRI owners as  described in the  Supplement,  but
such  reallocation  will  have no effect on the  partners  of either  Dorchester
Hugoton or Spinnaker.  Each unit of  Dorchester  Hugoton will still be exchanged
for one common unit of Dorchester  Minerals.  Each holder of Dorchester  Hugoton
units will still receive a liquidating  cash  distribution  upon the exchange of
its  Dorchester  Hugoton  units.  It is not  necessary  for  unitholders/limited
partners to vote on the  proposed  combination  again unless they wish to change
their vote.

     THE  SECURITIES TO BE OFFERED IN CONNECTION  WITH THE PROPOSED  TRANSACTION
WILL BE OFFERED  ONLY  PURSUANT TO A  PROSPECTUS/PROXY  STATEMENT  INCLUDED IN A
REGISTRATION STATEMENT FILED UNDER THE SECURITIES ACT OF 1933, AS AMENDED.
