UNITED SERVICES ADVISORS, INC.

                        1985 INCENTIVE STOCK OPTION PLAN
   
                           AS AMENDED NOVEMBER 7, 1989
                           AS AMENDED DECEMBER 9, 1991
    

1. PURPOSE OF THE PLAN. The United Services Advisors,  Inc. 1985 Incentive Stock
Option Plan (the "Plan") is designed to increase the interest of the  directors,
executive and other key salaried employees of United Services Advisors,  Inc., a
Texas  corporation  (the  "Company"),  and  its  subsidiaries  in the  Company's
business  through the added incentive  created by the  opportunity  afforded for
stock ownership under the Plan.

   
2. COMMITTEE. The Plan will be administered by a committee consisting of all the
independent, outside, non-employee directors of the Company. Any action taken by
a majority of the committee  shall be the action of the committee.  The decision
of the committee on any questions  concerning or involved in the  interpretation
or  administration  of the Plan  shall,  as between  the  Company and the option
holders,  be final and conclusive.  The committee may consult with counsel,  who
may be counsel for the Company, and shall not incur any liability for any action
taken in good faith in reliance upon the advice of counsel. Grants of options to
individuals  selected by the committee  will be subject to approval by the Board
of Directors and will become effective only upon such approval.  For purposes of
the  Plan,  the date of such  approval  shall be the date that  options  will be
granted  from  time to time  and the  periods  for  which  the  options  will be
outstanding will be determined by the committee.
    

3.  PARTICIPANTS.  Participants will be selected by the committee from among the
directors,  executive  and  key  salaried  employees  of the  Company  or of any
subsidiary of the Company,  including officers.  An employee on leave of absence
within the meaning of Section  1.421-7(h) of the Regulations  promulgated  under
the Internal Revenue Code of 1986, as amended (the "Code"), may be considered as
still in the employ of the Company for purposes of eligibility for participation
in the Plan.

4.  NUMBER OF  SHARES.  The total  number of shares of the  Company's  Preferred
Stock,  par value $0.05 per share,  which may be issued  under  options  granted
pursuant to the Plan shall not exceed 200,000. Shares subject to the Plan may be
either  authorized  but  unissued  shares or shares  that were once  issued  and
subsequently reacquired by the Company. If any stock option granted hereunder is
surrendered  before exercise or lapses without  exercise or for any other reason
ceases to be  exercisable,  the shares  reserved  therefor  shall continue to be
available  for the grant of options under the Plan.  The Plan will  terminate on
December 31, 1994, and no option will be granted thereunder after such date.

5. STOCK ADJUSTMENTS.  In the event that the outstanding shares of the Company's
Preferred  Stock are  increased or decreased or changed into or exchanged  for a
different  number or kind of shares or other  securities  of the  Company  or of
another corporation, through reorganization, merger, consolidation, liquidation,
recapitalization,  reclassification,  stock  split-up,  combination of shares or
dividends  payable  in  stock  of the  class  which  is  subject  to this  Plan,
appropriate  adjustment in the number and kind of shares as to which options may
be granted and as to which options or portions thereof then unexercised shall be
exercisable shall be made to the end that the proportionate  number of shares or
other  securities  as to which  options may be granted  and the option  holder's
proportionate  interest under outstanding  options shall be maintained as before
the  occurrence  of such  event.  Any such  adjustment  in the  shares  or other
securities  subject to  outstanding  options  (including  any  adjustment in the
option price),  shall be made in such manner as not to constitute a modification
as defined by subsection (h) (3) of Section 425 of the Code.

6. OPTION PRICE.  Subject to the  provisions of Section 10 concerning the option
price for ten  percent  shareholders,  the option  price will be the fair market
value of the shares at the date on which the respective options are granted. For
purposes of the Plan, the fair market value per share of the Company's Preferred
Stock on any date  shall be  deemed  to be the  closing  price of the  Company's
Preferred  Stock on the  principal  national  securities  exchange  on which the
Company's Preferred Stock is then listed or admitted to trading, if the





Company's  Preferred Stock is then listed or admitted to trading on any national
securities  exchange.  The closing  price shall be the last reported sale price,
regular  way,  or, in case no such sale takes place on such day,  the average of
the closing bid and asked prices regular way, as reported by said  exchange.  If
the  Company's  Preferred  Stock is not then so listed on a national  securities
exchange,  the fair market value per share of the Company's  Preferred  Stock on
any date shall be deemed to be the mean between the  representative  closing bid
and asked prices of the Company's Preferred Stock in the over-the-counter market
as  reported  by  the  National  Association  of  Securities  Dealers  Automated
Quotation  System  ("NASDAQ") or, if the Company's  Preferred  Stock is not then
quoted by NASDAQ,  as  furnished by any member of the  National  Association  of
Securities  Dealers,  Inc.  selected  from time to time by the  Company for that
purpose. If no member of the National  Association of Securities  Dealers,  Inc.
furnishes  quotes with respect to the Preferred Stock of the Company,  such fair
market  value  shall be  determined  by  resolution  of the  Company's  Board of
Directors.  Notwithstanding  the foregoing  provisions of this Section 6, if the
Board of Directors shall at any time determine that it is impracticable to apply
the foregoing  methods of determining  fair market value, the Board of Directors
is empowered to adopt other reasonable methods for such purpose.

7.  TERMS OF  OPTIONS.  Each  option  will  provide  by its terms that it is not
exercisable  after  the  expiration  of ten years  from the date such  option is
granted.  Within this  limitation  the committee  will  determine the expiration
dates of the options. Options may be exercised at any time or from time to time,
within their terms,  in whole or in part, or otherwise as shall be determined by
the  committee,  except  that  any  option  may not be  exercised  prior  to the
expiration  of six months  from the date of grant.  Upon  exercise,  the options
price  shall be  payable  in cash or the  equivalent  fair  market  value of the
Company's  Preferred  Stock or any combination of both as shall be determined by
the committee at the time the option is granted.

8. LISTING AND REGISTRATION.  The Company,  in its discretion,  may postpone the
issuance and delivery of shares upon any exercise of an option until  completion
of such stock exchange listing,  or registration or other  qualification of such
shares under any state or federal  law,  rule or  regulation  as the Company may
consider  appropriate;  and may require any person  exercising an option to make
such representations and furnish such information as it considers appropriate in
connection with the issuance of the shares in compliance with applicable law. In
addition,  the Company's  obligation to sell and deliver shares of the Preferred
Stock under this Plan is subject to the approval of any  governmental  authority
required in connection with the authorization, issuance or sale of such shares.

9. CONSIDERATION FOR GRANT OF OPTIONS. The grantee of an option will be required
to agree to remain in the employ of the Company or a  subsidiary  of the Company
for a period  of not less  than one year  from the date on which  the  option is
granted on such terms as shall be approved by the Board of Directors.

10. TEN PERCENT SHAREHOLDERS. No employee shall be eligible to receive an option
under  this Plan if, at the time the  option is  granted,  he owns more than ten
percent  of the  total  combined  voting  power of all  classes  of stock of the
Company or of its parent or  subsidiary  corporations  determined  in accordance
with Section 425(d) of the Code. This limitation shall not apply if, at the time
an option is granted, the option price is one hundred ten percent (I 10%) of the
fair  market  value of the  Company's  Preferred  Stock  and the  option  is not
exercisable after the expiration of five years from the date it is granted.

11.  LIMITATION ON VALUE OF SHARES.  The aggregate fair market value (determined
as of the time the option is  granted) of the stock for which any  employee  may
exercise  options for the first time in any calendar  year (under all  incentive
stock  option plans of the Company and its parent and  subsidiary  corporations)
shall not exceed $ 100,000.  For the purpose of this Plan, the terms  "incentive
stock options" and  "incentive  stock option plans" shall mean options and plans
which conform with the provisions of Section 422A of the Code.

12. FORM OF OPTIONS AND  CONDITIONS TO THEIR  EXERCISE.  It is intended that the
options  shall conform to the  requirements  of Section 422A and 425 of the Code
and to the  provisions of this Plan and shall  otherwise be as determined by the
committee and approved by the Board of Directors. The terms "parent corporation"
and





"subsidiary  corporation"  shall have the meanings  given them by Section 425 of
the Code.

         The  options  by  their  terms  will  provide  that  they  will  not be
transferable  by the grantee  otherwise  than by will or the laws of descent and
distribution  and that each is exercisable,  during the lifetime of the grantee,
only by him.

   
         An option may only be exercised after the expiration of six months from
the date of grant,  and may be exercised  only if at all times during the period
beginning  with the date of the granting of the option and ending on the date of
such exercise,  the grantee was an employee of either the Company or of a parent
or subsidiary  corporation of the Company or of another corporation  referred to
in  Section  422A(a)(2)  of the  Code,  unless  such  continuous  employment  is
terminated by such employer, or otherwise terminated with the written consent of
the employer.  If such  continuous  employment is so terminated,  the option may
also be  exercised  within  three  months  (one year if the  grantee is disabled
within the meaning of Section  22(e)(3) of the Code) after such  termination  to
the extent  exercisable  immediately prior to such termination,  but in no event
later than the termination date of the option.  If the grantee should die at any
time when any portion of the option shall be exercisable by him, the option will
be exercisable in whole or in part during the next year  succeeding his death by
the person or persons to whom his rights  under the option  will have  passed by
will or by the laws of descent and distribution, but in no event at a date later
than the termination of the option.
    

13.  AMENDMENT  OF PLAN.  The Plan may be  amended  at any time by the  board of
Directors provided that (except pursuant to Section 5) no amendment made without
approval of the  shareholders  of the Company shall increase the total number of
shares which may be issued under the options  granted  pursuant to the Plan,  or
reduce the minimum  option  price,  or extend the latest date upon which options
may be  granted  or shall be  exercisable,  or  change  the  class of  employees
eligible to receive options.

14.  CODE  REFERENCES.  References  to  sections  of the Code shall  include any
amendment of the Code section or any section  that may be  substituted  for such
section.

15. RIGHT OF COMPANY TO TERMINATE  EMPLOYMENT.  Nothing contained in the Plan or
in any option granted under the Plan shall confer upon any optionee any right to
continue in the employ of the Company or any parent or subsidiary of the Company
or  interfere  in any way  with  the  right  of the  Company  or any  parent  or
subsidiary  of the Company to terminate  the  employment  of the optionee at any
time,  with  or  without  cause,  except  as may be  otherwise  provided  in any
employment  agreement  between  the  optionee  and the  Company or any parent or
subsidiary of the Company.

16. GOVERNING LAW:  CONSTRUCTION.  The validity and construction of the Plan and
the instruments evidencing options shall be governed by the laws of the State of
Texas.  In construing  this Plan,  the singular shall include the plural and the
masculine  gender  shall  include the  feminine  and neuter,  unless the context
otherwise requires.

   
17.  SAVINGS  PROVISIONS.  With respect to persons  subject to Section 16 of the
Securities  Exchange  Act of 1934;  transactions  under the Plan are intended to
comply  with all  applicable  conditions  of Rule  16b-3 or any  successor  rule
promulgated  under the Act. To the extent any provision of the Plan or action by
the Board or the Committee fails to so comply, it shall be deemed null and void,
and the  remaining  portion  shall be valid to the extent  permitted  by law and
deemed advisable by the Board or the Committee.
