INTERIM OPERATIONS AGREEMENT

                                  SUMMARY

     1.  PacifiCare Holding would cause FHP to make a final contribution of 
$67 million to Talbert at the time of the closing of the FHP Merger.

     2.  FHP and Talbert would close the Stock Purchase Agreement (FHP has 
waived the condition that the Talbert S-1 be effective at such closing).

     3.  Talbert would on the next business day pay FHP the amount of the 
incorporate receivable at January 31, 1997 it owes FHP (currently estimated 
to be approximately $20 million).

     4.  Two PacifiCare Holding Nominees would immediately be placed on the 
Talbert Board, to remain there until the closing of the Talbert Rights 
offering.

     5.  If the Talbert Rights Offering has not commenced prior to the 
earlier of (i) May 15, 1997 or (ii) the date Talbert's cumulative operating 
losses since 1/1/97 exceed $14 million, the Talbert Board shall take such 
actions as are necessary to cause FHP nominees to represent a majority of the 
Talbert Board.

     6.  Until completion of the Rights Offering, Talbert will covenant not 
to take actions as set out on the attached Exhibit A.

     7.  Talbert and FHP will monthly pay any current or past amounts owed to 
the other.

     8.  Within two weeks after signing, Talbert will provide a reasonable 
explanation for the differences between the leased property FF&E schedule 
provided PacifiCare and the higher amount previously indicated as being the 
total for such schedule as well as the location of the assets shown on such 
schedule. The last sentence of Section 3.1 to the Stock Purchase Agreement 
(relating to the 338(h)(10) election) would be amended to read "The Parent's 
consent may not be withheld if Talbert pays FHP the amount mutually agreed as 
reflecting the negative economic impact of the election."

     9.  Should FHP nominees represent a majority of the Board pursuant to 
paragraph 5 above, PacifiCare Holding acknowledges the position of the 
holders who would receive Talbert Rights pursuant to the Reorganization 
Agreement and will consider their rights and expectations in any subsequent 
actions taken with respect to Talbert.
