           On December 18, 1998, PC Quote also issued to Holdings a Common Stock
Purchase Warrant covering 3,106,163 shares of PC Quote common stock (the
"December 1998 Warrant"). The terms of the December 1998 Warrant are more fully
described in Amendment No. 5.

           On May 2, 2000, at the request of Holdings, HyperFeed caused four
Common Stock Purchase Warrants covering an aggregate of 3,106,163 shares of PC
Quote common stock (now HyperFeed Shares) to be reissued in place of the
December 1998 Warrant: (a) one to Holdings covering 1,245,643 shares; (b) one to
Physicians covering 1,378,872 shares; (c) one to Citation covering 240,824
shares; and (d) one to Sequoia covering 240,824 shares. This reissuance
reflected more appropriately the conversion of outstanding indebtedness of PC
Quote held by Holdings, Physicians, Citation and Sequoia contemplated by the
1998 Purchase Agreement.

           Similarly, on August 17, 2000, at the request of Holdings, HyperFeed
reissued the 28,791 shares of Series B Preferred Stock which has been issued to
Holdings as follows: (a) to Holdings - 20,763 shares; (b) to Citation - 4,014
shares; and (c) to Sequoia - 4,014 shares. This reissuance also reflected more
appropriately the conversion of outstanding indebtedness of PC Quote held by
Physicians, Citation and Sequoia contemplated by the 1998 Purchase Agreement.

           Effective as of September 30, 2000, Holdings purchased from
Physicians the following securities: (a) 1,304,180 HyperFeed Shares, at a
purchase price of $3.74 per share; (b) Physicians' Common Stock Purchase Warrant
covering 1,378,872 HyperFeed Shares, at a purchase price of $3.74; and (c)
19,075 shares of Series A Preferred Stock, at a purchase price of $3.74 per
share. These purchases were subject to approval by the Ohio Department of
Insurance, which approval was given effective September 30, 2000. Holdings paid
Physicians cash in the aggregate amount of

                                       9

approximately $15 million in consideration for the HyperFeed Shares, the Common
Stock Purchase Warrant and the Series A Preferred Stock. Holdings used working
capital to fund the acquisition.

                  (g) "Exercise Date" shall mean the effective date of the
delivery of the Notice of Exercise pursuant to Section 4 below.

                  (h) "Holder" shall mean any person who shall at the time be
the registered holder of this Warrant.

                  (i) "Shares" shall mean shares of the Company's Common Stock,
as described in the Company's Certificate of Incorporation.

         2. ISSUANCE OF WARRANT AND CONSIDERATION THEREFOR. This Warrant is
issued in consideration for the renegotiation of the terms of a promissory note
issued by the Company and held by PICO HOLDINGS, INC. ("PICO") and the purchase
of preferred stock in the Company by PICO pursuant to that certain Securities
Purchase Agreement (the "Purchase Agreement") dated September 23, 1998 by and
among the Company, PICO and PHYSICIANS INSURANCE COMPANY OF OHIO ("PHYSICIANS").

         3. TERM. The purchase right represented by this Warrant is exercisable
only during the period commencing upon the Date of Grant and ending on April 30,
2005.

         4. METHOD OF EXERCISE AND PAYMENT.

                  (a) METHOD OF EXERCISE. Subject to Section 3 hereof and
compliance with all applicable Federal and state securities laws, the purchase
right represented by this Warrant may be exercised, in whole or in part and from
time to time, by the Holder by (i) surrender of this Warrant and delivery of the
Notice of Exercise (the form of which is attached hereto as EXHIBIT A), duly
executed, to the principal office of the Company and (ii) payment to the Company
of an amount equal to the product of the Warrant Price, as adjusted under
Section 5, multiplied by the number of Shares then being purchased pursuant to
one of the payment methods permitted under Section 4(b) below.

                  (b) METHOD OF PAYMENT. Payment shall be made either (1) by
check drawn on a United States bank and for United States funds made payable to
the Company, or (2) by wire transfer of United States funds for the account of
the Company.

                  (c) NET ISSUE EXERCISE. Notwithstanding any provisions herein
to the contrary, in lieu of payment of the exercise price in cash, the Holder
may elect to receive Shares equal to the value (as determined below) of this
Warrant (or the portion thereof being canceled) by surrender of this Warrant at
the principal office of the Company together with a properly endorsed notice of
exercise and notice of such election in which event the Company shall issue to
the Holder a number of Shares computed using the following formula:


<PAGE>   18

                                     Y(A-B)
                                 X= ----------
                                        A



Where             X =      The number of shares of Common Stock to be issued to
                           the Holder,

                  Y =      The number of shares of Common Stock purchasable
                           under the Warrant or, if only a portion of the
                           Warrant is being exercised, the portion of the
                           Warrant being canceled (at the date of such
                           calculation),

                  A =      The fair market value of one share of the Company's
                           Common Stock (at the date of such calculation), and

                  B =      The Warrant Price, as adjusted.

For purposes of the above calculation, fair market value of one Share shall be
determined by the Company's Board of Directors in good faith; provided, however,
that where there exists a public market for the Company's Common Stock at the
time of such exercise, fair market value shall mean the average over the
preceding twenty trading days (or such fewer number of days as such public
market has existed) of the mean of the closing bid and asked prices on the
over-the-counter market as reported by American Stock Exchange, or if the Common
Stock is then traded on a national securities exchange other than the American
Stock Exchange, the average over the preceding twenty trading days (or such
fewer number of days as the Common Stock has been so traded) of the closing sale
prices on the principal national securities exchange or the National Market on
which it is so traded.

                  (d) DELIVERY OF CERTIFICATE. In the event of any exercise of
the purchase right represented by this Warrant, certificates for the Shares so
purchased shall be delivered to the Holder within ten days of delivery of the
Notice of Exercise and, unless this Warrant has been fully exercised or has
expired, a new warrant representing the portion of the Shares with respect to
which this Warrant shall not then have been exercised shall also be issued to
the Holder within such ten day period.

                  (e) NO FRACTIONAL SHARES. No fractional Shares shall be issued
in connection with any exercise hereunder, but in lieu of such fractional Shares
the Company shall make a cash payment therefor upon the basis of the fair market
value per Share as of the date of exercise.

                  (f) COMPANY'S REPRESENTATIONS.

                          (i) All Shares which may be issued upon the exercise
of the purchase right represented by this Warrant shall, upon issuance, be duly
authorized, validly issued, fully paid and nonassessable, and free of any liens
and encumbrances except for restrictions on transfer under applicable federal
and state securities laws. During the period within which the purchase right
represented by this Warrant may be exercised, the Company shall at all times
have authorized, and reserved for the purpose of issuance upon exercise of the
purchase right represented by this Warrant, a sufficient number of Shares to
provide for the exercise of the purchase right represented by this Warrant;


<PAGE>   19


                         (ii) This Warrant has been duly authorized and executed
by the Company and is a valid and binding obligation of the Company enforceable
in accordance with its terms, subject to applicable bankruptcy, insolvency,
reorganization, moratorium or other laws of general application affecting the
enforcement of creditors' rights;

                         (iii) The execution and delivery of this Warrant are
not, and the issuance of the Shares upon exercise of this Warrant in accordance
with the terms hereof will not be inconsistent with the Company's Certificate of
Incorporation or Bylaws, do not and will not contravene any law, governmental
rule or regulation, judgment or order applicable to the Company, and do not and
will not conflict with or contravene any provision of, or constitute a default
under, any material indenture, mortgage, contract or other instrument of which
the Company is a party or by which it is bound, or require the registration or
filing with or the taking of any action in respect of or by, any federal, state
or local government authority or agency (other than such consents, approvals,
notices, actions, or filings as have already been obtained or made, as the case
may be).

         5. ADJUSTMENT OF WARRANT PRICE AND NUMBER OF SHARES. The number of
securities issuable upon the exercise of this Warrant and the Warrant Price
shall be subject to adjustment from time to time upon the occurrence of certain
events, as follows:

                  (a) ADJUSTMENT FOR DIVIDENDS IN STOCK. In case at any time or
from time to time on or after the date hereof the holders of the Common Stock of
the Company (or any shares of stock or other securities at the time receivable
upon the exercise of this Warrant) shall have received or, on or after the
record date fixed for the determination of eligible stockholders, shall have
become entitled to receive, without payment therefor, other or additional stock
of the Company by way of dividend then, and in each case, the Holder of this
Warrant shall, upon the exercise hereof, be entitled to receive, in addition to
the number of Shares receivable thereupon, and without payment of any additional
consideration therefor, the amount of such other or additional stock of the
Company which such Holder would hold on the date of such exercise had it been
the holder of record of such Common Stock on the date hereof and had thereafter,
during the period from the date hereof to and including the date of such
exercise, retained such Shares and/or all other additional stock receivable by
it as aforesaid during such period, giving effect to all adjustments called for
during such period by paragraphs (b) and (c) of this Section 5.

                  (b) ADJUSTMENT FOR RECLASSIFICATION OR REORGANIZATION. In case
of any reclassification or change of the outstanding securities of the Company
or of any consolidation, merger or reorganization of the Company on or after the
date hereof, then and in each such case the Holder of this Warrant, upon the
exercise hereof at any time after the consummation of such reclassification,
change, consolidation, merger or reorganization, shall be entitled to receive,
in lieu of or in addition to the stock or other securities and property
receivable upon the exercise hereof prior to such consummation, the stock or
other securities to which such Holder would have been entitled upon such
consummation if such Holder had exercised this Warrant immediately prior
thereto, all subject to further adjustment as provided in paragraphs (a) and
(c); in each such case, the terms of this Section 5 shall be applicable to the
shares of stock or other securities property receivable upon the exercise of
this Warrant after such consummation.


<PAGE>   20


                  (c) STOCK SPLITS AND REVERSE STOCK SPLITS. If, at any time on
or after the date hereof, the Company shall subdivide its outstanding Shares
into a greater number of Shares, the Warrant Price in effect immediately prior
to such subdivision shall thereby be proportionately reduced and the number of
Shares receivable upon exercise of this Warrant shall thereby be proportionately
increased; and, conversely, if at any time on or after the date hereof the
outstanding number of Shares shall be combined into a smaller number of Shares,
the Warrant Price in effect immediately prior to such combination shall thereby
be proportionately increased and the number of Shares receivable upon exercise
of the Warrant shall be proportionately decreased.

                  (d) RIGHTS, OPTIONS OR WARRANTS. If the Company issues rights,
options or warrants to all holders of its Shares, without any charge to such
holders, entitling them (for a period expiring within 45 days after the record
date mentioned below in this paragraph (d)) to subscribe for or to purchase
Shares at a price per share lower than the then current market price per Share
at the record date mentioned below (as defined in paragraph (f) below), the
number of Shares thereafter purchasable upon exercise of each Warrant shall be
determined by multiplying the number of Shares theretofore purchasable upon
exercise of each Warrant by a fraction, of which the numerator shall be the
number of Shares outstanding on such record date plus the number of additional
Shares offered for subscription or purchase, and of which the denominator shall
be the number of Shares outstanding on such record date plus the number of
Shares which the aggregate offering price of the total number of Shares so
offered would purchase at the then current market price per Share. Such
adjustment shall be made whenever such rights, options or warrants are issued,
and shall become effective retroactively to immediately after the record date
for the determination of stockholders entitled to receive such rights, options
or warrants.

                  (e) OTHER DISTRIBUTIONS. If the Company distributes to all
holders of its Shares shares of stock other than Common Stock or evidences of
its indebtedness or assets (excluding cash dividends payable out of consolidated
earnings or retained earnings and dividends or distributions referred to in
paragraph (a) above) or rights, options or warrants or convertible or
exchangeable securities containing the right to subscribe for or purchase Shares
(excluding those referenced in Section (2) above), then in each case the number
of Shares thereafter issuable upon the exercise of each warrant shall be
determined by multiplying the number of Shares theretofore issuable upon the
exercise of each Warrant, by a fraction, of which the numerator shall be the
current market price per Share (as defined in paragraph (f) below) on the record
date mentioned below in this paragraph (e), and of which the denominator shall
be the current market price per Share on such record date, less the then fair
value (as determined in good faith by the Board of Directors of the Company,
whose determination shall be conclusive) of the portion of the shares of stock
other than the Common Stock or assets or evidences of indebtedness so
distributed or of such subscription rights, options or warrants, or of such
convertible or exchangeable securities applicable to one Share. Such adjustment
shall be made whenever any such distribution is made, and shall become effective
on the date of distribution retroactive to immediately after the record date for
the determination of stockholders entitled to receive such distribution.

                  (f) CURRENT MARKET PRICE. For the purposes of any computation
under paragraphs (d) and (c) of this Section 5, the current market price per
Share at any date shall be the



<PAGE>   21


average of the daily closing prices for fifteen consecutive trading days
commencing twenty trading days before the date of such computation. The closing
price for each day shall be the closing sale price or in case no such reported
sale takes place on such day, the average of the closing bid and asked prices
for such day, in either case on the American Stock Exchange or such other
principal national securities exchange or National Market on which the Shares
are listed or admitted to trading, or if they are not listed or admitted to
trading on any national securities exchange or the National Association of
Securities Dealers Automated Quotation ("NASDAQ") National Market, but are
traded in the over-the-counter market, the average of the representative closing
bid and asked quotations for the Common Stock, on the NASDAQ system or any
comparable system, or, in case no sale is publicly reported, the average of the
closing bid and asked prices as furnished by two members of the National
Association of Securities Dealers selected by the Company for that purpose.

                  (g) ADJUSTMENTS TO WARRANT PRICE. Whenever the number of
Shares purchasable upon exercise of this Warrant is adjusted, as herein
provided, the Warrant Price shall be adjusted by multiplying the Warrant Price
in effect immediately prior to such adjustment by a fraction, of which the
numerator shall be the number of Shares purchasable upon the exercise of this
Warrant immediately prior to such adjustment, and of which the denominator shall
be the number of Shares so purchasable immediately thereafter.

                  (h) CERTIFICATE AS TO ADJUSTMENTS. Upon each adjustment of the
Warrant Price, the Company at its expense shall promptly compute such
adjustment, and furnish the Holder with a certificate of its Chief Financial
Officer setting forth such adjustment and the facts upon which such adjustment
is based. The Company shall, upon written request, furnish the Holder a
certificate setting forth the Warrant Price in effect upon the date thereof and
the series of adjustments leading to such Warrant Price.

         6. ACQUISITIONS

                  (a) ASSUMPTION OF WARRANT. If upon the closing of any
Acquisition the successor entity assumes the obligations of this Warrant, then
this Warrant shall be exercisable for the same securities, cash, and property as
would be payable for the Shares issuable upon exercise of the unexercised
portion of this Warrant as if such Shares were outstanding on the record date
for the Acquisition and subsequent closing.

                  (b) NONASSUMPTION. If upon the closing of any Acquisition the
successor entity does not assume the obligations of this Warrant and the Holder
has not otherwise exercised this Warrant in full, then the unexercised portion
of this Warrant shall be deemed to have been automatically converted pursuant to
Section 4(c) and thereafter the Holder shall participate in the acquisition on
the same terms as other holders of the same class of securities of the Company.

                  (c) PURCHASE RIGHT. Notwithstanding the foregoing, at the
election of the Holder, the Company shall purchase the unexercised portion of
this Warrant for cash upon the closing of any Acquisition for an amount equal to
(a) the fair market value of any consideration that would have been received by
the Holder in consideration of the Shares had the Holder exercised the



<PAGE>   22


unexercised portion of this Warrant immediately before the record date for
determining the stockholders entitled to participate in the proceeds of the
Acquisition, less (b) the aggregate Warrant Price of the Shares, but in no event
less than zero.

         7. NOTICES; INFORMATION; REGISTRATION.

                  (a) NOTICE OF CERTAIN EVENTS. If the Company proposes at any
time (a) to declare any dividend or distribution upon its Common Stock, whether
in cash, property, stock, or other securities and whether or not a regular cash
dividend; (b) to offer for subscription pro rata to the holders of any class or
series of its stock any additional shares of stock of any class or series or
other rights; (c) to effect any reclassification or recapitalization of Common
Stock; (d) to merge or consolidate with or into any other corporation, or sell,
lease, license, or convey all or substantially all of its assets, or to
liquidate, dissolve or wind up; or (e) offer holders of registration rights the
opportunity to participate in an underwritten public offering of the company's
securities for cash, then, in connection with each such event, the Company shall
give the Holder (1) at least 20 days prior written notice of the date on which a
record will be taken for such dividend, distribution, or subscription rights
(and specifying the date on which the holders of Common Stock will be entitled
thereto) or in respect of the matters referred to in (c) and (d) above for
determining rights to vote, if any; (2) in the case of the matters referred to
in (c) and (d) above at least 20 days prior written notice of the date when the
same will take place (and specifying the date on which the holders of Common
Stock will be entitled to exchange their Common Stock for securities or other
property deliverable upon the occurrence of such event); and (3) in the case of
the matter referred to in (e) above, the same notice as is given to the holders
of such registration rights.

                  (b) INFORMATION RIGHTS. So long as the Holder holds this
Warrant and/or any of the Shares acquired on exercise of this Warrant, the
Company shall deliver to the Holder (a) promptly after mailing, copies of all
notices or other written communications to the stockholders of the Company, (b)
within ninety days after the end of each fiscal year of the Company, the annual
audited financial statements of the Company audited by independent public
accountants of recognized standing and (c) within forty-five days after the end
of each of the first three quarters of each fiscal year, the Company's
quarterly, unaudited financial statements.

                  (c) REGISTRATION UNDER SECURITIES ACT OF 1933. The Company
agrees that the Shares underlying this Warrant shall be "Registrable Securities"
under that certain Registration Rights Agreement, dated December 18, 1998, among
the Company, PICO and PHYSICIANS.



<PAGE>   23


         8. COMPLIANCE WITH ACT; TRANSFERABILITY AND NEGOTIABILITY OF WARRANT;
DISPOSITION OF SHARES.


                  (a) COMPLIANCE WITH ACT. The Holder, by acceptance hereof,
agrees that this Warrant and the Shares to be issued upon the exercise hereof
are being acquired solely for its own account and not as a nominee for any other
party and not with a view toward the resale or distribution thereof and that it
will not offer, sell or otherwise dispose of this Warrant or any Shares to be
issued upon the exercise hereof except under circumstances which will not result
in a violation of the Act. This Warrant and the Shares to be issued upon the
exercise hereof (unless registered under the Act) shall be imprinted with a
legend in substantially the following form:

         THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
         SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED,
         ASSIGNED OR HYPOTHECATED UNLESS THERE IS AN EFFECTIVE REGISTRATION
         STATEMENT UNDER SUCH ACT COVERING SUCH SECURITIES, THE SALE IS MADE IN
         ACCORDANCE WITH RULE 144 UNDER THE ACT, OR THE COMPANY RECEIVES AN
         OPINION OF COUNSEL FOR THE HOLDER OF THESE SECURITIES REASONABLY
         SATISFACTORY TO THE COMPANY, STATING THAT SUCH SALE, TRANSFER,
         ASSIGNMENT OR HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND
         PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT.

In addition, this Warrant and the Shares to be issued upon the exercise hereof
shall bear any legends required by the securities laws of any applicable states.

                  (b) TRANSFERABILITY AND NEGOTIABILITY OF WARRANT. This Warrant
may not be transferred or assigned in whole or in part without compliance with
all applicable federal and state securities laws by the transferor and the
transferee (including the delivery of investment representation letters and
legal opinions reasonably satisfactory to the Company, if reasonably requested
by the Company and the transfer is to a person other than a general partner or
affiliate of the initial Holder). Subject to the provisions of this Warrant with
respect to compliance with the Act, title to this Warrant may be transferred by
endorsement and delivery in the same manner as a negotiable instrument
transferable by endorsement and delivery. The Company shall act promptly to
record transfers of this Warrant on its books, but the Company may treat the
registered holder of this Warrant as the absolute owner of this Warrant for all
purposes, notwithstanding any notice to the contrary.

                  (c) DISPOSITION OF SHARES. With respect to any offer, sale,
transfer or other disposition of any Shares acquired pursuant to the exercise of
this Warrant prior to registration of such Shares, except for any such offer,
sale, transfer or other disposition of Shares to an affiliate of the initial
Holder, the Holder and each subsequent holder of this Warrant agrees to give
written notice to the Company prior thereto, describing briefly the manner
thereof, and if such transfer is not pursuant to Rule 144, a written opinion of
legal counsel for such holder, if requested by the Company, to the effect that
such offer, sale or other disposition may be effected without registration



<PAGE>   24


or qualification of such Shares. Notwithstanding the foregoing, such Shares may
be offered, sold or otherwise disposed of in accordance with Rule 144, provided
that the Company shall have been furnished with such information as the Company
may reasonably request to provide a reasonable assurance that the provisions of
Rule 144 have been satisfied. Each certificate representing the Shares thus
transferred (except a transfer pursuant to Rule 144) shall bear a restrictive
legend as to the applicable restrictions on transferability in order to insure
compliance with the Act, unless in the aforesaid opinion of legal counsel for
the holder, such legend is not required in order to insure compliance with the
Act.

         9. RIGHTS OF STOCKHOLDERS. No Holder shall be entitled to vote or
receive dividends or be deemed the holder of Shares or any other securities of
the Company which may at any time be issuable on the exercise of this Warrant
for any purpose, nor shall anything contained herein be construed to confer upon
the Holder, as such, any of the rights of a stockholder of the Company or any
right to vote for the election of directors or upon any matter submitted to
stockholders at any meeting thereof, or to give or withhold consent to any
corporate action (whether upon any recapitalization, issuance of stock,
reclassification of stock, consolidation, merger, transfer of assets or
otherwise) or, except as expressly required herein, to receive notice of
meetings, or to receive dividends or subscription rights or otherwise until this
Warrant shall have been exercised and the Shares issuable upon exercise hereof
shall have become deliverable, as provided herein.

         10. REPLACEMENT OF WARRANTS. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of an
indemnity agreement reasonably satisfactory in form and amount to the Company
or, in the case of mutilation, on surrender and cancellation of this Warrant,
the Company at its expense shall execute and deliver, in lieu of this Warrant, a
new warrant of like tenor.

         11. EXCHANGE OF WARRANT. Subject to the other provisions of this
Warrant, on surrender of this Warrant for exchange, and subject to the
provisions of this Warrant with respect to compliance with the Act, the Company
at its expense shall issue to or on the order of the Holder a new warrant or
warrants of like tenor, in the name of the Holder or as the Holder (on payment
by the Holder of any applicable transfer taxes) may direct, for the number of
Shares issuable upon exercise thereof.

         12. NOTICES. All notices and other communications from the Company to
the Holder, or vice versa, shall be deemed delivered and effective when given
personally or mailed by first-class registered or certified mail, postage
prepaid, at such address as may have been furnished to the Company or the
Holder, as the case may be, in writing by the Company or such Holder from time
to time.

         13. WAIVER.  This Warrant and any term hereof may be changed,
waived, discharged or terminated only by an instrument in writing signed by the
party against which enforcement of such change, waiver, discharge or termination
is sought.


<PAGE>   25



         14. GOVERNING LAW. This Warrant shall be governed by and construed in
accordance with the laws of the State of California.

         15. TITLES AND SUBTITLES; FORMS OF PRONOUNS. The titles of the Sections

                                                       Void after April 30, 2005

<PAGE>   29



                  (f) "Date of Grant" shall mean December 18, 1998.

                  (g) "Exercise Date" shall mean the effective date of the
delivery of the Notice of Exercise pursuant to Section 4 below.

                  (h) "Holder" shall mean any person who shall at the time be
the registered holder of this Warrant.

                  (i) "Shares" shall mean shares of the Company's Common Stock,
as described in the Company's Certificate of Incorporation.

         2. ISSUANCE OF WARRANT AND CONSIDERATION THEREFOR. This Warrant is
issued in consideration for the renegotiation of the terms of a promissory note
issued by the Company and held by PICO HOLDINGS, INC. ("PICO") and the purchase
of preferred stock in the Company by PICO pursuant to that certain Securities
Purchase Agreement (the "Purchase Agreement") dated September 23, 1998 by and
among the Company, PICO and PHYSICIANS INSURANCE COMPANY OF OHIO ("PHYSICIANS").

         3. TERM. The purchase right represented by this Warrant is exercisable
only during the period commencing upon the Date of Grant and ending on April 30,
2005.

         4. METHOD OF EXERCISE AND PAYMENT.

                  (a) METHOD OF EXERCISE. Subject to Section 3 hereof and
compliance with all applicable Federal and state securities laws, the purchase
right represented by this Warrant may be exercised, in whole or in part and from
time to time, by the Holder by (i) surrender of this Warrant and delivery of the
Notice of Exercise (the form of which is attached hereto as EXHIBIT A), duly
executed, to the principal office of the Company and (ii) payment to the Company
of an amount equal to the product of the Warrant Price, as adjusted under
Section 5, multiplied by the number of Shares then being purchased pursuant to
one of the payment methods permitted under Section 4(b) below.

                  (b) METHOD OF PAYMENT. Payment shall be made either (1) by
check drawn on a United States bank and for United States funds made payable to
the Company, or (2) by wire transfer of United States funds for the account of
the Company.

                  (c) NET ISSUE EXERCISE. Notwithstanding any provisions herein
to the contrary, in lieu of payment of the exercise price in cash, the Holder
may elect to receive Shares equal to the value (as determined below) of this
Warrant (or the portion thereof being canceled) by surrender of this Warrant at
the principal office of the Company together with a properly endorsed notice of
exercise and notice of such election in which event the Company shall issue to
the Holder a number of Shares computed using the following formula:


<PAGE>   30

                                     Y(A-B)
                                 X= ----------
                                        A




Where  X =     The number of shares of Common Stock to be issued to the Holder,
       Y =     The number of shares of Common Stock purchasable under the
               Warrant or, if only a portion of the Warrant is being
               exercised, the portion of the Warrant being canceled (at the
               date of such calculation),
       A =     The fair market value of one share of the Company's Common
               Stock (at the date of such
               calculation), and
       B =     The Warrant Price, as adjusted.

For purposes of the above calculation, fair market value of one Share shall be
determined by the Company's Board of Directors in good faith; provided, however,
that where there exists a public market for the Company's Common Stock at the
time of such exercise, fair market value shall mean the average over the
preceding twenty trading days (or such fewer number of days as such public
market has existed) of the mean of the closing bid and asked prices on the
over-the-counter market as reported by American Stock Exchange, or if the Common
Stock is then traded on a national securities exchange other than the American
Stock Exchange, the average over the preceding twenty trading days (or such
fewer number of days as the Common Stock has been so traded) of the closing sale
prices on the principal national securities exchange or the National Market on
which it is so traded.

                  (d) DELIVERY OF CERTIFICATE. In the event of any exercise of
the purchase right represented by this Warrant, certificates for the Shares so
purchased shall be delivered to the Holder within ten days of delivery of the
Notice of Exercise and, unless this Warrant has been fully exercised or has
expired, a new warrant representing the portion of the Shares with respect to
which this Warrant shall not then have been exercised shall also be issued to
the Holder within such ten day period.

                  (e) NO FRACTIONAL SHARES. No fractional Shares shall be issued
in connection with any exercise hereunder, but in lieu of such fractional Shares
the Company shall make a cash payment therefor upon the basis of the fair market
value per Share as of the date of exercise.

                  (f) COMPANY'S REPRESENTATIONS.

                          (i) All Shares which may be issued upon the exercise
of the purchase right represented by this Warrant shall, upon issuance, be duly
authorized, validly issued, fully paid and nonassessable, and free of any liens
and encumbrances except for restrictions on transfer under applicable federal
and state securities laws. During the period within which the purchase right
represented by this Warrant may be exercised, the Company shall at all times
have authorized, and reserved for the purpose of issuance upon exercise of the
purchase right represented by this Warrant, a sufficient number of Shares to
provide for the exercise of the purchase right represented by this Warrant;


<PAGE>   31



                         (ii) This Warrant has been duly authorized and executed
by the Company and is a valid and binding obligation of the Company enforceable
in accordance with its terms, subject to applicable bankruptcy, insolvency,
reorganization, moratorium or other laws of general application affecting the
enforcement of creditors' rights;

                         (iii) The execution and delivery of this Warrant are
not, and the issuance of the Shares upon exercise of this Warrant in accordance
with the terms hereof will not be inconsistent with the Company's Certificate of
Incorporation or Bylaws, do not and will not contravene any law, governmental
rule or regulation, judgment or order applicable to the Company, and do not and
will not conflict with or contravene any provision of, or constitute a default
under, any material indenture, mortgage, contract or other instrument of which
the Company is a party or by which it is bound, or require the registration or
filing with or the taking of any action in respect of or by, any federal, state
or local government authority or agency (other than such consents, approvals,
notices, actions, or filings as have already been obtained or made, as the case
may be).

         5. ADJUSTMENT OF WARRANT PRICE AND NUMBER OF SHARES. The number of
securities issuable upon the exercise of this Warrant and the Warrant Price
shall be subject to adjustment from time to time upon the occurrence of certain
events, as follows:

                  (a) ADJUSTMENT FOR DIVIDENDS IN STOCK. In case at any time or
from time to time on or after the date hereof the holders of the Common Stock of
the Company (or any shares of stock or other securities at the time receivable
upon the exercise of this Warrant) shall have received or, on or after the
record date fixed for the determination of eligible stockholders, shall have
become entitled to receive, without payment therefor, other or additional stock
of the Company by way of dividend then, and in each case, the Holder of this
Warrant shall, upon the exercise hereof, be entitled to receive, in addition to
the number of Shares receivable thereupon, and without payment of any additional
consideration therefor, the amount of such other or additional stock of the
Company which such Holder would hold on the date of such exercise had it been
the holder of record of such Common Stock on the date hereof and had thereafter,
during the period from the date hereof to and including the date of such
exercise, retained such Shares and/or all other additional stock receivable by
it as aforesaid during such period, giving effect to all adjustments called for
during such period by paragraphs (b) and (c) of this Section 5.

                  (b) ADJUSTMENT FOR RECLASSIFICATION OR REORGANIZATION. In case
of any reclassification or change of the outstanding securities of the Company
or of any consolidation, merger or reorganization of the Company on or after the
date hereof, then and in each such case the Holder of this Warrant, upon the
exercise hereof at any time after the consummation of such reclassification,
change, consolidation, merger or reorganization, shall be entitled to receive,
in lieu of or in addition to the stock or other securities and property
receivable upon the exercise hereof prior to such consummation, the stock or
other securities to which such Holder would have been entitled upon such
consummation if such Holder had exercised this Warrant immediately prior
thereto, all subject to further adjustment as provided in paragraphs (a) and
(c); in each such case, the terms of this Section 5 shall be applicable to the
shares of stock or other securities property receivable upon the exercise of
this Warrant after such consummation.


<PAGE>   32



                  (c) STOCK SPLITS AND REVERSE STOCK SPLITS. If, at any time on
or after the date hereof, the Company shall subdivide its outstanding Shares
into a greater number of Shares, the Warrant Price in effect immediately prior
to such subdivision shall thereby be proportionately reduced and the number of
Shares receivable upon exercise of this Warrant shall thereby be proportionately
increased; and, conversely, if at any time on or after the date hereof the
outstanding number of Shares shall be combined into a smaller number of Shares,
the Warrant Price in effect immediately prior to such combination shall thereby
be proportionately increased and the number of Shares receivable upon exercise
of the Warrant shall be proportionately decreased.

                  (d) RIGHTS, OPTIONS OR WARRANTS. If the Company issues rights,
options or warrants to all holders of its Shares, without any charge to such
holders, entitling them (for a period expiring within 45 days after the record
date mentioned below in this paragraph (d)) to subscribe for or to purchase
Shares at a price per share lower than the then current market price per Share
at the record date mentioned below (as defined in paragraph (f) below), the
number of Shares thereafter purchasable upon exercise of each Warrant shall be
determined by multiplying the number of Shares theretofore purchasable upon
exercise of each Warrant by a fraction, of which the numerator shall be the
number of Shares outstanding on such record date plus the number of additional
Shares offered for subscription or purchase, and of which the denominator shall
be the number of Shares outstanding on such record date plus the number of
Shares which the aggregate offering price of the total number of Shares so
offered would purchase at the then current market price per Share. Such
adjustment shall be made whenever such rights, options or warrants are issued,
and shall become effective retroactively to immediately after the record date
for the determination of stockholders entitled to receive such rights, options
or warrants.

                  (e) OTHER DISTRIBUTIONS. If the Company distributes to all
holders of its Shares shares of stock other than Common Stock or evidences of
its indebtedness or assets (excluding cash dividends payable out of consolidated
earnings or retained earnings and dividends or distributions referred to in
paragraph (a) above) or rights, options or warrants or convertible or
exchangeable securities containing the right to subscribe for or purchase Shares
(excluding those referenced in Section (2) above), then in each case the number
of Shares thereafter issuable upon the exercise of each warrant shall be
determined by multiplying the number of Shares theretofore issuable upon the
exercise of each Warrant, by a fraction, of which the numerator shall be the
current market price per Share (as defined in paragraph (f) below) on the record
date mentioned below in this paragraph (e), and of which the denominator shall
be the current market price per Share on such record date, less the then fair
value (as determined in good faith by the Board of Directors of the Company,
whose determination shall be conclusive) of the portion of the shares of stock
other than the Common Stock or assets or evidences of indebtedness so
distributed or of such subscription rights, options or warrants, or of such
convertible or exchangeable securities applicable to one Share. Such adjustment
shall be made whenever any such distribution is made, and shall become effective
on the date of distribution retroactive to immediately after the record date for
the determination of stockholders entitled to receive such distribution.

         (f) CURRENT MARKET PRICE. For the purposes of any computation under
paragraphs (d) and (c) of this Section 5, the current market price per Share at
any date shall be the



<PAGE>   33


average of the daily closing prices for fifteen consecutive trading days
commencing twenty trading days before the date of such computation. The closing
price for each day shall be the closing sale price or in case no such reported
sale takes place on such day, the average of the closing bid and asked prices
for such day, in either case on the American Stock Exchange or such other
principal national securities exchange or National Market on which the Shares
are listed or admitted to trading, or if they are not listed or admitted to
trading on any national securities exchange or the National Association of
Securities Dealers Automated Quotation ("NASDAQ") National Market, but are
traded in the over-the-counter market, the average of the representative closing
bid and asked quotations for the Common Stock, on the NASDAQ system or any
comparable system, or, in case no sale is publicly reported, the average of the
closing bid and asked prices as furnished by two members of the National
Association of Securities Dealers selected by the Company for that purpose.

                  (g) ADJUSTMENTS TO WARRANT PRICE. Whenever the number of
Shares purchasable upon exercise of this Warrant is adjusted, as herein
provided, the Warrant Price shall be adjusted by multiplying the Warrant Price
in effect immediately prior to such adjustment by a fraction, of which the
numerator shall be the number of Shares purchasable upon the exercise of this
Warrant immediately prior to such adjustment, and of which the denominator shall
be the number of Shares so purchasable immediately thereafter.

                  (h) CERTIFICATE AS TO ADJUSTMENTS. Upon each adjustment of the
Warrant Price, the Company at its expense shall promptly compute such
adjustment, and furnish the Holder with a certificate of its Chief Financial
Officer setting forth such adjustment and the facts upon which such adjustment
is based. The Company shall, upon written request, furnish the Holder a
certificate setting forth the Warrant Price in effect upon the date thereof and
the series of adjustments leading to such Warrant Price.

         6.       ACQUISITIONS

                  (a) ASSUMPTION OF WARRANT. If upon the closing of any
Acquisition the successor entity assumes the obligations of this Warrant, then
this Warrant shall be exercisable for the same securities, cash, and property as
would be payable for the Shares issuable upon exercise of the unexercised
portion of this Warrant as if such Shares were outstanding on the record date
for the Acquisition and subsequent closing.

                  (b) NONASSUMPTION. If upon the closing of any Acquisition the
successor entity does not assume the obligations of this Warrant and the Holder
has not otherwise exercised this Warrant in full, then the unexercised portion
of this Warrant shall be deemed to have been automatically converted pursuant to
Section 4(c) and thereafter the Holder shall participate in the acquisition on
the same terms as other holders of the same class of securities of the Company.

                  (c) PURCHASE RIGHT. Notwithstanding the foregoing, at the
election of the Holder, the Company shall purchase the unexercised portion of
this Warrant for cash upon the closing of any Acquisition for an amount equal to
(a) the fair market value of any consideration that would have been received by
the Holder in consideration of the Shares had the Holder exercised the



<PAGE>   34


unexercised portion of this Warrant immediately before the record date for
determining the stockholders entitled to participate in the proceeds of the
Acquisition, less (b) the aggregate Warrant Price of the Shares, but in no event
less than zero.

         7.       NOTICES; INFORMATION; REGISTRATION.

                  (a) NOTICE OF CERTAIN EVENTS. If the Company proposes at any
time (a) to declare any dividend or distribution upon its Common Stock, whether
in cash, property, stock, or other securities and whether or not a regular cash
dividend; (b) to offer for subscription pro rata to the holders of any class or
series of its stock any additional shares of stock of any class or series or
other rights; (c) to effect any reclassification or recapitalization of Common
Stock; (d) to merge or consolidate with or into any other corporation, or sell,
lease, license, or convey all or substantially all of its assets, or to
liquidate, dissolve or wind up; or (e) offer holders of registration rights the
opportunity to participate in an underwritten public offering of the company's
securities for cash, then, in connection with each such event, the Company shall
give the Holder (1) at least 20 days prior written notice of the date on which a
record will be taken for such dividend, distribution, or subscription rights
(and specifying the date on which the holders of Common Stock will be entitled
thereto) or in respect of the matters referred to in (c) and (d) above for
determining rights to vote, if any; (2) in the case of the matters referred to
in (c) and (d) above at least 20 days prior written notice of the date when the
same will take place (and specifying the date on which the holders of Common
Stock will be entitled to exchange their Common Stock for securities or other
property deliverable upon the occurrence of such event); and (3) in the case of
the matter referred to in (e) above, the same notice as is given to the holders
of such registration rights.

                  (b) INFORMATION RIGHTS. So long as the Holder holds this
Warrant and/or any of the Shares acquired on exercise of this Warrant, the
Company shall deliver to the Holder (a) promptly after mailing, copies of all
notices or other written communications to the stockholders of the Company, (b)
within ninety days after the end of each fiscal year of the Company, the annual
audited financial statements of the Company audited by independent public
accountants of recognized standing and (c) within forty-five days after the end
of each of the first three quarters of each fiscal year, the Company's
quarterly, unaudited financial statements.

                  (c) REGISTRATION UNDER SECURITIES ACT OF 1933. The Company
agrees that the Shares underlying this Warrant shall be "Registrable Securities"
under that certain Registration Rights Agreement, dated December 18, 1998, among
the Company, PICO and PHYSICIANS.


<PAGE>   35


         8.       COMPLIANCE WITH ACT; TRANSFERABILITY AND NEGOTIABILITY OF
WARRANT; DISPOSITION OF SHARES.

                  (a) COMPLIANCE WITH ACT. The Holder, by acceptance hereof,
agrees that this Warrant and the Shares to be issued upon the exercise hereof
are being acquired solely for its own account and not as a nominee for any other
party and not with a view toward the resale or distribution thereof and that it
will not offer, sell or otherwise dispose of this Warrant or any Shares to be
issued upon the exercise hereof except under circumstances which will not result
in a violation of the Act. This Warrant and the Shares to be issued upon the
exercise hereof (unless registered under the Act) shall be imprinted with a
legend in substantially the following form:

         THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
         SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED,
         ASSIGNED OR HYPOTHECATED UNLESS THERE IS AN EFFECTIVE REGISTRATION
         STATEMENT UNDER SUCH ACT COVERING SUCH SECURITIES, THE SALE IS MADE IN
         ACCORDANCE WITH RULE 144 UNDER THE ACT, OR THE COMPANY RECEIVES AN
         OPINION OF COUNSEL FOR THE HOLDER OF THESE SECURITIES REASONABLY
         SATISFACTORY TO THE COMPANY, STATING THAT SUCH SALE, TRANSFER,
         ASSIGNMENT OR HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND
         PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT.

In addition, this Warrant and the Shares to be issued upon the exercise hereof
shall bear any legends required by the securities laws of any applicable states.

                  (b) TRANSFERABILITY AND NEGOTIABILITY OF WARRANT. This Warrant
may not be transferred or assigned in whole or in part without compliance with
all applicable federal and state securities laws by the transferor and the
transferee (including the delivery of investment representation letters and
legal opinions reasonably satisfactory to the Company, if reasonably requested
by the Company and the transfer is to a person other than a general partner or
affiliate of the initial Holder). Subject to the provisions of this Warrant with
respect to compliance with the Act, title to this Warrant may be transferred by
endorsement and delivery in the same manner as a negotiable instrument
transferable by endorsement and delivery. The Company shall act promptly to
record transfers of this Warrant on its books, but the Company may treat the
registered holder of this Warrant as the absolute owner of this Warrant for all
purposes, notwithstanding any notice to the contrary.

                  (c) DISPOSITION OF SHARES. With respect to any offer, sale,
transfer or other disposition of any Shares acquired pursuant to the exercise of
this Warrant prior to registration of such Shares, except for any such offer,
sale, transfer or other disposition of Shares to an affiliate of the initial
Holder, the Holder and each subsequent holder of this Warrant agrees to give
written notice to the Company prior thereto, describing briefly the manner
thereof, and if such transfer is not pursuant to Rule 144, a written opinion of
legal counsel for such holder, if requested by the Company, to the effect that
such offer, sale or other disposition may be effected without registration



<PAGE>   36


or qualification of such Shares. Notwithstanding the foregoing, such Shares may
be offered, sold or otherwise disposed of in accordance with Rule 144, provided
that the Company shall have been furnished with such information as the Company
may reasonably request to provide a reasonable assurance that the provisions of
Rule 144 have been satisfied. Each certificate representing the Shares thus
transferred (except a transfer pursuant to Rule 144) shall bear a restrictive
legend as to the applicable restrictions on transferability in order to insure
compliance with the Act, unless in the aforesaid opinion of legal counsel for
the holder, such legend is not required in order to insure compliance with the
Act.

         9. RIGHTS OF STOCKHOLDERS. No Holder shall be entitled to vote or
receive dividends or be deemed the holder of Shares or any other securities of
the Company which may at any time be issuable on the exercise of this Warrant
for any purpose, nor shall anything contained herein be construed to confer upon
the Holder, as such, any of the rights of a stockholder of the Company or any
right to vote for the election of directors or upon any matter submitted to
stockholders at any meeting thereof, or to give or withhold consent to any
corporate action (whether upon any recapitalization, issuance of stock,
reclassification of stock, consolidation, merger, transfer of assets or
otherwise) or, except as expressly required herein, to receive notice of
meetings, or to receive dividends or subscription rights or otherwise until this
Warrant shall have been exercised and the Shares issuable upon exercise hereof
shall have become deliverable, as provided herein.

         10. REPLACEMENT OF WARRANTS. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of an
indemnity agreement reasonably satisfactory in form and amount to the Company
or, in the case of mutilation, on surrender and cancellation of this Warrant,
the Company at its expense shall execute and deliver, in lieu of this Warrant, a
new warrant of like tenor.

         11. EXCHANGE OF WARRANT. Subject to the other provisions of this
Warrant, on surrender of this Warrant for exchange, and subject to the
provisions of this Warrant with respect to compliance with the Act, the Company
at its expense shall issue to or on the order of the Holder a new warrant or
warrants of like tenor, in the name of the Holder or as the Holder (on payment
by the Holder of any applicable transfer taxes) may direct, for the number of

                  (b) "Acquisition" shall mean any sale, license, or other
disposition of all or substantially all of the assets of the Company, or any

                  (c) "Commission" shall mean the Securities and Exchange

Common Stock may hereafter be exchanged.

                  (e) "Company" shall mean PC QUOTE, INC., a Delaware

<PAGE>   41



                  (f) "Date of Grant" shall mean December 18, 1998.

                  (g) "Exercise Date" shall mean the effective date of the
delivery of the Notice of Exercise pursuant to Section 4 below.

                  (h) "Holder" shall mean any person who shall at the time be
the registered holder of this Warrant.

                  (i) "Shares" shall mean shares of the Company's Common Stock,
as described in the Company's Certificate of Incorporation.

         2. ISSUANCE OF WARRANT AND CONSIDERATION THEREFOR. This Warrant is
issued in consideration for the renegotiation of the terms of a promissory note
issued by the Company and held by PICO HOLDINGS, INC. ("PICO") and the purchase
of preferred stock in the Company by PICO pursuant to that certain Securities
Purchase Agreement (the "Purchase Agreement") dated September 23, 1998 by and
among the Company, PICO and PHYSICIANS INSURANCE COMPANY OF OHIO ("PHYSICIANS").

         3. TERM. The purchase right represented by this Warrant is exercisable
only during the period commencing upon the Date of Grant and ending on April 30,
2005.

         4. METHOD OF EXERCISE AND PAYMENT.

                  (a) METHOD OF EXERCISE. Subject to Section 3 hereof and
compliance with all applicable Federal and state securities laws, the purchase
right represented by this Warrant may be exercised, in whole or in part and from
time to time, by the Holder by (i) surrender of this Warrant and delivery of the
Notice of Exercise (the form of which is attached hereto as EXHIBIT A), duly
executed, to the principal office of the Company and (ii) payment to the Company
of an amount equal to the product of the Warrant Price, as adjusted under
Section 5, multiplied by the number of Shares then being purchased pursuant to
one of the payment methods permitted under Section 4(b) below.

                  (b) METHOD OF PAYMENT. Payment shall be made either (1) by
check drawn on a United States bank and for United States funds made payable to
the Company, or (2) by wire transfer of United States funds for the account of
the Company.

                  (c) NET ISSUE EXERCISE. Notwithstanding any provisions herein
to the contrary, in lieu of payment of the exercise price in cash, the Holder
may elect to receive Shares equal to the value (as determined below) of this
Warrant (or the portion thereof being canceled) by surrender of this Warrant at
the principal office of the Company together with a properly endorsed notice of
exercise and notice of such election in which event the Company shall issue to
the Holder a number of Shares computed using the following formula:


<PAGE>   42
                                     Y(A-B)
                                 X= ----------
                                        A


Where   X =     The number of shares of Common Stock to be issued to the Holder,
        Y =     The number of shares of Common Stock purchasable under the
                Warrant or, if only a portion of the Warrant is being
                exercised, the portion of the Warrant being canceled (at the
                date of such calculation),
        A =     The fair market value of one share of the Company's Common
                Stock (at the date of such calculation), and
        B =     The Warrant Price, as adjusted.

For purposes of the above calculation, fair market value of one Share shall be
determined by the Company's Board of Directors in good faith; provided, however,
that where there exists a public market for the Company's Common Stock at the
time of such exercise, fair market value shall mean the average over the
preceding twenty trading days (or such fewer number of days as such public
market has existed) of the mean of the closing bid and asked prices on the
over-the-counter market as reported by American Stock Exchange, or if the Common
Stock is then traded on a national securities exchange other than the American
Stock Exchange, the average over the preceding twenty trading days (or such
fewer number of days as the Common Stock has been so traded) of the closing sale
prices on the principal national securities exchange or the National Market on
which it is so traded.

                  (d) DELIVERY OF CERTIFICATE. In the event of any exercise of
the purchase right represented by this Warrant, certificates for the Shares so
purchased shall be delivered to the Holder within ten days of delivery of the
Notice of Exercise and, unless this Warrant has been fully exercised or has
expired, a new warrant representing the portion of the Shares with respect to
which this Warrant shall not then have been exercised shall also be issued to
the Holder within such ten day period.

                  (e) NO FRACTIONAL SHARES. No fractional Shares shall be issued
in connection with any exercise hereunder, but in lieu of such fractional Shares
the Company shall make a cash payment therefor upon the basis of the fair market
value per Share as of the date of exercise.

                  (f) COMPANY'S REPRESENTATIONS.

                           (i) All Shares which may be issued upon the exercise
of the purchase right represented by this Warrant shall, upon issuance, be duly
authorized, validly issued, fully paid and nonassessable, and free of any liens
and encumbrances except for restrictions on transfer under applicable federal
and state securities laws. During the period within which the purchase right
represented by this Warrant may be exercised, the Company shall at all times
have authorized, and reserved for the purpose of issuance upon exercise of the
purchase right represented by this Warrant, a sufficient number of Shares to
provide for the exercise of the purchase right represented by this Warrant;


<PAGE>   43



                         (ii) This Warrant has been duly authorized and executed
by the Company and is a valid and binding obligation of the Company enforceable
in accordance with its terms, subject to applicable bankruptcy, insolvency,
reorganization, moratorium or other laws of general application affecting the
enforcement of creditors' rights;

                         (iii) The execution and delivery of this Warrant are
not, and the issuance of the Shares upon exercise of this Warrant in accordance
with the terms hereof will not be inconsistent with the Company's Certificate of
Incorporation or Bylaws, do not and will not contravene any law, governmental
rule or regulation, judgment or order applicable to the Company, and do not and
will not conflict with or contravene any provision of, or constitute a default
under, any material indenture, mortgage, contract or other instrument of which
the Company is a party or by which it is bound, or require the registration or
filing with or the taking of any action in respect of or by, any federal, state
or local government authority or agency (other than such consents, approvals,
notices, actions, or filings as have already been obtained or made, as the case
may be).

         5. ADJUSTMENT OF WARRANT PRICE AND NUMBER OF SHARES. The number of
securities issuable upon the exercise of this Warrant and the Warrant Price
shall be subject to adjustment from time to time upon the occurrence of certain
events, as follows:

                  (a) ADJUSTMENT FOR DIVIDENDS IN STOCK. In case at any time or
from time to time on or after the date hereof the holders of the Common Stock of
the Company (or any shares of stock or other securities at the time receivable
upon the exercise of this Warrant) shall have received or, on or after the
record date fixed for the determination of eligible stockholders, shall have
become entitled to receive, without payment therefor, other or additional stock
of the Company by way of dividend then, and in each case, the Holder of this
Warrant shall, upon the exercise hereof, be entitled to receive, in addition to
the number of Shares receivable thereupon, and without payment of any additional
consideration therefor, the amount of such other or additional stock of the
Company which such Holder would hold on the date of such exercise had it been
the holder of record of such Common Stock on the date hereof and had thereafter,
during the period from the date hereof to and including the date of such
exercise, retained such Shares and/or all other additional stock receivable by
it as aforesaid during such period, giving effect to all adjustments called for
during such period by paragraphs (b) and (c) of this Section 5.

                  (b) ADJUSTMENT FOR RECLASSIFICATION OR REORGANIZATION. In case
of any reclassification or change of the outstanding securities of the Company
or of any consolidation, merger or reorganization of the Company on or after the
date hereof, then and in each such case the Holder of this Warrant, upon the
exercise hereof at any time after the consummation of such reclassification,
change, consolidation, merger or reorganization, shall be entitled to receive,
in lieu of or in addition to the stock or other securities and property
receivable upon the exercise hereof prior to such consummation, the stock or
other securities to which such Holder would have been entitled upon such
consummation if such Holder had exercised this Warrant immediately prior
thereto, all subject to further adjustment as provided in paragraphs (a) and
(c); in each such case, the terms of this Section 5 shall be applicable to the
shares of stock or other securities property receivable upon the exercise of
this Warrant after such consummation.


<PAGE>   44



                  (c) STOCK SPLITS AND REVERSE STOCK SPLITS. If, at any time on
or after the date hereof, the Company shall subdivide its outstanding Shares
into a greater number of Shares, the Warrant Price in effect immediately prior
to such subdivision shall thereby be proportionately reduced and the number of
Shares receivable upon exercise of this Warrant shall thereby be proportionately
increased; and, conversely, if at any time on or after the date hereof the
outstanding number of Shares shall be combined into a smaller number of Shares,
the Warrant Price in effect immediately prior to such combination shall thereby
be proportionately increased and the number of Shares receivable upon exercise
of the Warrant shall be proportionately decreased.

                  (d) RIGHTS, OPTIONS OR WARRANTS. If the Company issues rights,
options or warrants to all holders of its Shares, without any charge to such
holders, entitling them (for a period expiring within 45 days after the record
date mentioned below in this paragraph (d)) to subscribe for or to purchase
Shares at a price per share lower than the then current market price per Share
at the record date mentioned below (as defined in paragraph (f) below), the
number of Shares thereafter purchasable upon exercise of each Warrant shall be
determined by multiplying the number of Shares theretofore purchasable upon
exercise of each Warrant by a fraction, of which the numerator shall be the
number of Shares outstanding on such record date plus the number of additional
Shares offered for subscription or purchase, and of which the denominator shall
be the number of Shares outstanding on such record date plus the number of
Shares which the aggregate offering price of the total number of Shares so
offered would purchase at the then current market price per Share. Such
adjustment shall be made whenever such rights, options or warrants are issued,
and shall become effective retroactively to immediately after the record date
for the determination of stockholders entitled to receive such rights, options
or warrants.

                  (e) OTHER DISTRIBUTIONS. If the Company distributes to all
holders of its Shares shares of stock other than Common Stock or evidences of
its indebtedness or assets (excluding cash dividends payable out of consolidated
earnings or retained earnings and dividends or distributions referred to in
paragraph (a) above) or rights, options or warrants or convertible or
exchangeable securities containing the right to subscribe for or purchase Shares
(excluding those referenced in Section (2) above), then in each case the number
of Shares thereafter issuable upon the exercise of each warrant shall be
determined by multiplying the number of Shares theretofore issuable upon the
exercise of each Warrant, by a fraction, of which the numerator shall be the
current market price per Share (as defined in paragraph (f) below) on the record
date mentioned below in this paragraph (e), and of which the denominator shall
be the current market price per Share on such record date, less the then fair
value (as determined in good faith by the Board of Directors of the Company,
whose determination shall be conclusive) of the portion of the shares of stock
other than the Common Stock or assets or evidences of indebtedness so
distributed or of such subscription rights, options or warrants, or of such
convertible or exchangeable securities applicable to one Share. Such adjustment
shall be made whenever any such distribution is made, and shall become effective
on the date of distribution retroactive to immediately after the record date for
the determination of stockholders entitled to receive such distribution.

                  (f) CURRENT MARKET PRICE. For the purposes of any computation
under paragraphs (d) and (c) of this Section 5, the current market price per
Share at any date shall be the



<PAGE>   45


average of the daily closing prices for fifteen consecutive trading days
commencing twenty trading days before the date of such computation. The closing
price for each day shall be the closing sale price or in case no such reported
sale takes place on such day, the average of the closing bid and asked prices
for such day, in either case on the American Stock Exchange or such other
principal national securities exchange or National Market on which the Shares
are listed or admitted to trading, or if they are not listed or admitted to
trading on any national securities exchange or the National Association of
Securities Dealers Automated Quotation ("NASDAQ") National Market, but are
traded in the over-the-counter market, the average of the representative closing
bid and asked quotations for the Common Stock, on the NASDAQ system or any
comparable system, or, in case no sale is publicly reported, the average of the
closing bid and asked prices as furnished by two members of the National
Association of Securities Dealers selected by the Company for that purpose.

                  (g) ADJUSTMENTS TO WARRANT PRICE. Whenever the number of
Shares purchasable upon exercise of this Warrant is adjusted, as herein
provided, the Warrant Price shall be adjusted by multiplying the Warrant Price
in effect immediately prior to such adjustment by a fraction, of which the
numerator shall be the number of Shares purchasable upon the exercise of this
Warrant immediately prior to such adjustment, and of which the denominator shall
be the number of Shares so purchasable immediately thereafter.

                  (h) CERTIFICATE AS TO ADJUSTMENTS. Upon each adjustment of the
Warrant Price, the Company at its expense shall promptly compute such
adjustment, and furnish the Holder with a certificate of its Chief Financial
Officer setting forth such adjustment and the facts upon which such adjustment
is based. The Company shall, upon written request, furnish the Holder a
certificate setting forth the Warrant Price in effect upon the date thereof and
the series of adjustments leading to such Warrant Price.

         6.       ACQUISITIONS

                  (a) ASSUMPTION OF WARRANT. If upon the closing of any
Acquisition the successor entity assumes the obligations of this Warrant, then
this Warrant shall be exercisable for the same securities, cash, and property as
would be payable for the Shares issuable upon exercise of the unexercised
portion of this Warrant as if such Shares were outstanding on the record date
for the Acquisition and subsequent closing.

                  (b) NONASSUMPTION. If upon the closing of any Acquisition the
successor entity does not assume the obligations of this Warrant and the Holder
has not otherwise exercised this Warrant in full, then the unexercised portion
of this Warrant shall be deemed to have been automatically converted pursuant to
Section 4(c) and thereafter the Holder shall participate in the acquisition on
the same terms as other holders of the same class of securities of the Company.

                  (c) PURCHASE RIGHT. Notwithstanding the foregoing, at the
election of the Holder, the Company shall purchase the unexercised portion of
this Warrant for cash upon the closing of any Acquisition for an amount equal to
(a) the fair market value of any consideration that would have been received by
the Holder in consideration of the Shares had the Holder exercised the



<PAGE>   46


unexercised portion of this Warrant immediately before the record date for
determining the stockholders entitled to participate in the proceeds of the
Acquisition, less (b) the aggregate Warrant Price of the Shares, but in no event
less than zero.

         7.       NOTICES; INFORMATION; REGISTRATION.

                  (a) NOTICE OF CERTAIN EVENTS. If the Company proposes at any
time (a) to declare any dividend or distribution upon its Common Stock, whether
in cash, property, stock, or other securities and whether or not a regular cash
dividend; (b) to offer for subscription pro rata to the holders of any class or
series of its stock any additional shares of stock of any class or series or
other rights; (c) to effect any reclassification or recapitalization of Common
Stock; (d) to merge or consolidate with or into any other corporation, or sell,
lease, license, or convey all or substantially all of its assets, or to
liquidate, dissolve or wind up; or (e) offer holders of registration rights the
opportunity to participate in an underwritten public offering of the company's
securities for cash, then, in connection with each such event, the Company shall
give the Holder (1) at least 20 days prior written notice of the date on which a
record will be taken for such dividend, distribution, or subscription rights
(and specifying the date on which the holders of Common Stock will be entitled
thereto) or in respect of the matters referred to in (c) and (d) above for
determining rights to vote, if any; (2) in the case of the matters referred to
in (c) and (d) above at least 20 days prior written notice of the date when the
same will take place (and specifying the date on which the holders of Common
Stock will be entitled to exchange their Common Stock for securities or other
property deliverable upon the occurrence of such event); and (3) in the case of
the matter referred to in (e) above, the same notice as is given to the holders
of such registration rights.

                  (b) INFORMATION RIGHTS. So long as the Holder holds this
Warrant and/or any of the Shares acquired on exercise of this Warrant, the
Company shall deliver to the Holder (a) promptly after mailing, copies of all
notices or other written communications to the stockholders of the Company, (b)
within ninety days after the end of each fiscal year of the Company, the annual
audited financial statements of the Company audited by independent public
accountants of recognized standing and (c) within forty-five days after the end
of each of the first three quarters of each fiscal year, the Company's
quarterly, unaudited financial statements.

                  (c) REGISTRATION UNDER SECURITIES ACT OF 1933. The Company
agrees that the Shares underlying this Warrant shall be "Registrable Securities"
under that certain Registration Rights Agreement, dated December 18, 1998, among
the Company, PICO and PHYSICIANS.

         8.       COMPLIANCE WITH ACT; TRANSFERABILITY AND NEGOTIABILITY OF
                  WARRANT; DISPOSITION OF SHARES.

                  (a) COMPLIANCE WITH ACT. The Holder, by acceptance hereof,
agrees that this Warrant and the Shares to be issued upon the exercise hereof
are being acquired solely for its own account and not as a nominee for any other
party and not with a view toward the resale or distribution thereof and that it
will not offer, sell or otherwise dispose of this Warrant or any Shares to be
issued upon the exercise hereof except under circumstances which will not result
in a violation of the Act. This Warrant and the Shares to be issued upon the
exercise hereof (unless registered under the Act) shall be imprinted with a
legend in substantially the following form:

         THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
         SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED,
         ASSIGNED OR HYPOTHECATED UNLESS THERE IS AN EFFECTIVE REGISTRATION
         STATEMENT UNDER SUCH ACT COVERING SUCH SECURITIES, THE SALE IS MADE IN
         ACCORDANCE WITH RULE 144 UNDER THE ACT, OR THE COMPANY RECEIVES AN
         OPINION OF COUNSEL FOR THE HOLDER OF THESE SECURITIES REASONABLY
         SATISFACTORY TO THE COMPANY, STATING THAT SUCH SALE, TRANSFER,
         ASSIGNMENT OR HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND
         PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT.

In addition, this Warrant and the Shares to be issued upon the exercise hereof
shall bear any legends required by the securities laws of any applicable states.

                  (b) TRANSFERABILITY AND NEGOTIABILITY OF WARRANT. This Warrant
may not be transferred or assigned in whole or in part without compliance with
all applicable federal and state securities laws by the transferor and the
transferee (including the delivery of investment representation letters and
legal opinions reasonably satisfactory to the Company, if reasonably requested
by the Company and the transfer is to a person other than a general partner or
affiliate of the initial Holder). Subject to the provisions of this Warrant with
respect to compliance with the Act, title to this Warrant may be transferred by
endorsement and delivery in the same manner as a negotiable instrument
transferable by endorsement and delivery. The Company shall act promptly to
record transfers of this Warrant on its books, but the Company may treat the
registered holder of this Warrant as the absolute owner of this Warrant for all
purposes, notwithstanding any notice to the contrary.

                  (c) DISPOSITION OF SHARES. With respect to any offer, sale,
transfer or other disposition of any Shares acquired pursuant to the exercise of
this Warrant prior to registration of such Shares, except for any such offer,
sale, transfer or other disposition of Shares to an affiliate of the initial
Holder, the Holder and each subsequent holder of this Warrant agrees to give
written notice to the Company prior thereto, describing briefly the manner
thereof, and if such transfer is not pursuant to Rule 144, a written opinion of
legal counsel for such holder, if requested by the Company, to the effect that
such offer, sale or other disposition may be effected without registration


<PAGE>   48


or qualification of such Shares. Notwithstanding the foregoing, such Shares may
be offered, sold or otherwise disposed of in accordance with Rule 144, provided
that the Company shall have been furnished with such information as the Company
may reasonably request to provide a reasonable assurance that the provisions of
Rule 144 have been satisfied. Each certificate representing the Shares thus
transferred (except a transfer pursuant to Rule 144) shall bear a restrictive
legend as to the applicable restrictions on transferability in order to insure
compliance with the Act, unless in the aforesaid opinion of legal counsel for
the holder, such legend is not required in order to insure compliance with the
Act.

         9. RIGHTS OF STOCKHOLDERS. No Holder shall be entitled to vote or
receive dividends or be deemed the holder of Shares or any other securities of
the Company which may at any time be issuable on the exercise of this Warrant
for any purpose, nor shall anything contained herein be construed to confer upon
the Holder, as such, any of the rights of a stockholder of the Company or any
right to vote for the election of directors or upon any matter submitted to
stockholders at any meeting thereof, or to give or withhold consent to any
corporate action (whether upon any recapitalization, issuance of stock,
reclassification of stock, consolidation, merger, transfer of assets or
otherwise) or, except as expressly required herein, to receive notice of
meetings, or to receive dividends or subscription rights or otherwise until this
Warrant shall have been exercised and the Shares issuable upon exercise hereof
shall have become deliverable, as provided herein.

         10. REPLACEMENT OF WARRANTS. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of an
indemnity agreement reasonably satisfactory in form and amount to the Company
or, in the case of mutilation, on surrender and cancellation of this Warrant,
the Company at its expense shall execute and deliver, in lieu of this Warrant, a
new warrant of like tenor.

         11. EXCHANGE OF WARRANT. Subject to the other provisions of this
Warrant, on surrender of this Warrant for exchange, and subject to the
provisions of this Warrant with respect to compliance with the Act, the Company
at its expense shall issue to or on the order of the Holder a new warrant or
warrants of like tenor, in the name of the Holder or as the Holder (on payment
by the Holder of any applicable transfer taxes) may direct, for the number of
Shares issuable upon exercise thereof.

         12. NOTICES. All notices and other communications from the Company to
the Holder, or vice versa, shall be deemed delivered and effective when given
personally or mailed by first-class registered or certified mail, postage
prepaid, at such address as may have been furnished to the Company or the
Holder, as the case may be, in writing by the Company or such Holder from time
to time.

         13. WAIVER. This Warrant and any term hereof may be changed, waived,

                  (b) "Acquisition" shall mean any sale, license, or other
disposition of all or substantially all of the assets of the Company, or any

                  (c) "Commission" shall mean the Securities and Exchange

<PAGE>   53

                  (g) "Exercise Date" shall mean the effective date of the

                  (h) "Holder" shall mean any person who shall at the time be
the registered holder of this Warrant.

                  (i) "Shares" shall mean shares of the Company's Common Stock,
as described in the Company's Certificate of Incorporation.

         2. ISSUANCE OF WARRANT AND CONSIDERATION THEREFOR. This Warrant is
issued in consideration for the renegotiation of the terms of a promissory note
issued by the Company and held by PICO HOLDINGS, INC. ("PICO") and the purchase
of preferred stock in the Company by PICO pursuant to that certain Securities
Purchase Agreement (the "Purchase Agreement") dated September 23, 1998 by and
among the Company, PICO and PHYSICIANS INSURANCE COMPANY OF OHIO ("PHYSICIANS").

         3. TERM. The purchase right represented by this Warrant is exercisable
only during the period commencing upon the Date of Grant and ending on April 30,
2005.

         4. METHOD OF EXERCISE AND PAYMENT.

                  (a) METHOD OF EXERCISE. Subject to Section 3 hereof and
compliance with all applicable Federal and state securities laws, the purchase
right represented by this Warrant may be exercised, in whole or in part and from
time to time, by the Holder by (i) surrender of this Warrant and delivery of the
Notice of Exercise (the form of which is attached hereto as EXHIBIT A), duly
executed, to the principal office of the Company and (ii) payment to the Company
of an amount equal to the product of the Warrant Price, as adjusted under
Section 5, multiplied by the number of Shares then being purchased pursuant to
one of the payment methods permitted under Section 4(b) below.

                  (b) METHOD OF PAYMENT. Payment shall be made either (1) by
check drawn on a United States bank and for United States funds made payable to
the Company, or (2) by wire transfer of United States funds for the account of
the Company.

                  (c) NET ISSUE EXERCISE. Notwithstanding any provisions herein
to the contrary, in lieu of payment of the exercise price in cash, the Holder
may elect to receive Shares equal to the value (as determined below) of this
Warrant (or the portion thereof being canceled) by surrender of this Warrant at
the principal office of the Company together with a properly endorsed notice of
exercise and notice of such election in which event the Company shall issue to
the Holder a number of Shares computed using the following formula:


<PAGE>   54
                                     Y(A-B)
                                X= ------------
                                        A



Where   X =     The number of shares of Common Stock to be issued to the Holder,
        Y =     The number of shares of Common Stock purchasable under the
                Warrant or, if only a portion of the Warrant is being
                exercised, the portion of the Warrant being canceled (at the
                date of such calculation),
        A =     The fair market value of one share of the Company's Common
                Stock (at the date of such calculation), and
        B =     The Warrant Price, as adjusted.

For purposes of the above calculation, fair market value of one Share shall be
determined by the Company's Board of Directors in good faith; provided, however,
that where there exists a public market for the Company's Common Stock at the
time of such exercise, fair market value shall mean the average over the
preceding twenty trading days (or such fewer number of days as such public
market has existed) of the mean of the closing bid and asked prices on the
over-the-counter market as reported by American Stock Exchange, or if the Common
Stock is then traded on a national securities exchange other than the American
Stock Exchange, the average over the preceding twenty trading days (or such
fewer number of days as the Common Stock has been so traded) of the closing sale
prices on the principal national securities exchange or the National Market on
which it is so traded.

                  (d) DELIVERY OF CERTIFICATE. In the event of any exercise of
the purchase right represented by this Warrant, certificates for the Shares so
purchased shall be delivered to the Holder within ten days of delivery of the
Notice of Exercise and, unless this Warrant has been fully exercised or has
expired, a new warrant representing the portion of the Shares with respect to
which this Warrant shall not then have been exercised shall also be issued to
the Holder within such ten day period.

                  (e) NO FRACTIONAL SHARES. No fractional Shares shall be issued
in connection with any exercise hereunder, but in lieu of such fractional Shares
the Company shall make a cash payment therefor upon the basis of the fair market
value per Share as of the date of exercise.

                  (f) COMPANY'S REPRESENTATIONS.

                          (i) All Shares which may be issued upon the exercise
of the purchase right represented by this Warrant shall, upon issuance, be duly
authorized, validly issued, fully paid and nonassessable, and free of any liens
and encumbrances except for restrictions on transfer under applicable federal
and state securities laws. During the period within which the purchase right
represented by this Warrant may be exercised, the Company shall at all times
have authorized, and reserved for the purpose of issuance upon exercise of the
purchase right represented by this Warrant, a sufficient number of Shares to
provide for the exercise of the purchase right represented by this Warrant;


<PAGE>   55



                         (ii) This Warrant has been duly authorized and executed
by the Company and is a valid and binding obligation of the Company enforceable
in accordance with its terms, subject to applicable bankruptcy, insolvency,
reorganization, moratorium or other laws of general application affecting the
enforcement of creditors' rights;

                         (iii) The execution and delivery of this Warrant are
not, and the issuance of the Shares upon exercise of this Warrant in accordance
with the terms hereof will not be inconsistent with the Company's Certificate of
Incorporation or Bylaws, do not and will not contravene any law, governmental
rule or regulation, judgment or order applicable to the Company, and do not and
will not conflict with or contravene any provision of, or constitute a default
under, any material indenture, mortgage, contract or other instrument of which
the Company is a party or by which it is bound, or require the registration or
filing with or the taking of any action in respect of or by, any federal, state
or local government authority or agency (other than such consents, approvals,
notices, actions, or filings as have already been obtained or made, as the case
may be).

         5. ADJUSTMENT OF WARRANT PRICE AND NUMBER OF SHARES. The number of
securities issuable upon the exercise of this Warrant and the Warrant Price
shall be subject to adjustment from time to time upon the occurrence of certain
events, as follows:

                  (a) ADJUSTMENT FOR DIVIDENDS IN STOCK. In case at any time or
from time to time on or after the date hereof the holders of the Common Stock of
the Company (or any shares of stock or other securities at the time receivable
upon the exercise of this Warrant) shall have received or, on or after the
record date fixed for the determination of eligible stockholders, shall have
become entitled to receive, without payment therefor, other or additional stock
of the Company by way of dividend then, and in each case, the Holder of this
Warrant shall, upon the exercise hereof, be entitled to receive, in addition to
the number of Shares receivable thereupon, and without payment of any additional
consideration therefor, the amount of such other or additional stock of the
Company which such Holder would hold on the date of such exercise had it been
the holder of record of such Common Stock on the date hereof and had thereafter,
during the period from the date hereof to and including the date of such
exercise, retained such Shares and/or all other additional stock receivable by
it as aforesaid during such period, giving effect to all adjustments called for
during such period by paragraphs (b) and (c) of this Section 5.

                  (b) ADJUSTMENT FOR RECLASSIFICATION OR REORGANIZATION. In case
of any reclassification or change of the outstanding securities of the Company
or of any consolidation, merger or reorganization of the Company on or after the
date hereof, then and in each such case the Holder of this Warrant, upon the
exercise hereof at any time after the consummation of such reclassification,
change, consolidation, merger or reorganization, shall be entitled to receive,
in lieu of or in addition to the stock or other securities and property
receivable upon the exercise hereof prior to such consummation, the stock or
other securities to which such Holder would have been entitled upon such
consummation if such Holder had exercised this Warrant immediately prior
thereto, all subject to further adjustment as provided in paragraphs (a) and
(c); in each such case, the terms of this Section 5 shall be applicable to the
shares of stock or other securities property receivable upon the exercise of
this Warrant after such consummation.


<PAGE>   56



                  (c) STOCK SPLITS AND REVERSE STOCK SPLITS. If, at any time on
or after the date hereof, the Company shall subdivide its outstanding Shares
into a greater number of Shares, the Warrant Price in effect immediately prior
to such subdivision shall thereby be proportionately reduced and the number of
Shares receivable upon exercise of this Warrant shall thereby be proportionately
increased; and, conversely, if at any time on or after the date hereof the
outstanding number of Shares shall be combined into a smaller number of Shares,
the Warrant Price in effect immediately prior to such combination shall thereby
be proportionately increased and the number of Shares receivable upon exercise
of the Warrant shall be proportionately decreased.

                  (d) RIGHTS, OPTIONS OR WARRANTS. If the Company issues rights,
options or warrants to all holders of its Shares, without any charge to such
holders, entitling them (for a period expiring within 45 days after the record
date mentioned below in this paragraph (d)) to subscribe for or to purchase
Shares at a price per share lower than the then current market price per Share
at the record date mentioned below (as defined in paragraph (f) below), the
number of Shares thereafter purchasable upon exercise of each Warrant shall be
determined by multiplying the number of Shares theretofore purchasable upon
exercise of each Warrant by a fraction, of which the numerator shall be the
number of Shares outstanding on such record date plus the number of additional
Shares offered for subscription or purchase, and of which the denominator shall
be the number of Shares outstanding on such record date plus the number of
Shares which the aggregate offering price of the total number of Shares so
offered would purchase at the then current market price per Share. Such
adjustment shall be made whenever such rights, options or warrants are issued,
and shall become effective retroactively to immediately after the record date
for the determination of stockholders entitled to receive such rights, options
or warrants.

                  (e) OTHER DISTRIBUTIONS. If the Company distributes to all
holders of its Shares shares of stock other than Common Stock or evidences of
its indebtedness or assets (excluding cash dividends payable out of consolidated
earnings or retained earnings and dividends or distributions referred to in
paragraph (a) above) or rights, options or warrants or convertible or
exchangeable securities containing the right to subscribe for or purchase Shares
(excluding those referenced in Section (2) above), then in each case the number
of Shares thereafter issuable upon the exercise of each warrant shall be
determined by multiplying the number of Shares theretofore issuable upon the
exercise of each Warrant, by a fraction, of which the numerator shall be the
current market price per Share (as defined in paragraph (f) below) on the record
date mentioned below in this paragraph (e), and of which the denominator shall
be the current market price per Share on such record date, less the then fair
value (as determined in good faith by the Board of Directors of the Company,
whose determination shall be conclusive) of the portion of the shares of stock
other than the Common Stock or assets or evidences of indebtedness so
distributed or of such subscription rights, options or warrants, or of such
convertible or exchangeable securities applicable to one Share. Such adjustment
shall be made whenever any such distribution is made, and shall become effective
on the date of distribution retroactive to immediately after the record date for
the determination of stockholders entitled to receive such distribution.

                   (f) CURRENT MARKET PRICE. For the purposes of any computation
under paragraphs (d) and (c) of this Section 5, the current market price per
Share at any date shall be the



<PAGE>   57


average of the daily closing prices for fifteen consecutive trading days
commencing twenty trading days before the date of such computation. The closing
price for each day shall be the closing sale price or in case no such reported
sale takes place on such day, the average of the closing bid and asked prices
for such day, in either case on the American Stock Exchange or such other
principal national securities exchange or National Market on which the Shares
are listed or admitted to trading, or if they are not listed or admitted to
trading on any national securities exchange or the National Association of
Securities Dealers Automated Quotation ("NASDAQ") National Market, but are
traded in the over-the-counter market, the average of the representative closing
bid and asked quotations for the Common Stock, on the NASDAQ system or any
comparable system, or, in case no sale is publicly reported, the average of the
closing bid and asked prices as furnished by two members of the National
Association of Securities Dealers selected by the Company for that purpose.

                  (g) ADJUSTMENTS TO WARRANT PRICE. Whenever the number of
Shares purchasable upon exercise of this Warrant is adjusted, as herein
provided, the Warrant Price shall be adjusted by multiplying the Warrant Price
in effect immediately prior to such adjustment by a fraction, of which the
numerator shall be the number of Shares purchasable upon the exercise of this
Warrant immediately prior to such adjustment, and of which the denominator shall
be the number of Shares so purchasable immediately thereafter.

                  (h) CERTIFICATE AS TO ADJUSTMENTS. Upon each adjustment of the
Warrant Price, the Company at its expense shall promptly compute such
adjustment, and furnish the Holder with a certificate of its Chief Financial
Officer setting forth such adjustment and the facts upon which such adjustment
is based. The Company shall, upon written request, furnish the Holder a
certificate setting forth the Warrant Price in effect upon the date thereof and
the series of adjustments leading to such Warrant Price.

         6. ACQUISITIONS

                  (a) ASSUMPTION OF WARRANT. If upon the closing of any
Acquisition the successor entity assumes the obligations of this Warrant, then
this Warrant shall be exercisable for the same securities, cash, and property as
would be payable for the Shares issuable upon exercise of the unexercised
portion of this Warrant as if such Shares were outstanding on the record date
for the Acquisition and subsequent closing.

                  (b) NONASSUMPTION. If upon the closing of any Acquisition the
successor entity does not assume the obligations of this Warrant and the Holder
has not otherwise exercised this Warrant in full, then the unexercised portion
of this Warrant shall be deemed to have been automatically converted pursuant to
Section 4(c) and thereafter the Holder shall participate in the acquisition on
the same terms as other holders of the same class of securities of the Company.

                  (c) PURCHASE RIGHT. Notwithstanding the foregoing, at the
election of the Holder, the Company shall purchase the unexercised portion of
this Warrant for cash upon the closing of any Acquisition for an amount equal to
(a) the fair market value of any consideration that would have been received by
the Holder in consideration of the Shares had the Holder exercised the



<PAGE>   58


unexercised portion of this Warrant immediately before the record date for
determining the stockholders entitled to participate in the proceeds of the
Acquisition, less (b) the aggregate Warrant Price of the Shares, but in no event
less than zero.

         7. NOTICES; INFORMATION; REGISTRATION.

                  (a) NOTICE OF CERTAIN EVENTS. If the Company proposes at any
time (a) to declare any dividend or distribution upon its Common Stock, whether
in cash, property, stock, or other securities and whether or not a regular cash
dividend; (b) to offer for subscription pro rata to the holders of any class or
series of its stock any additional shares of stock of any class or series or
other rights; (c) to effect any reclassification or recapitalization of Common
Stock; (d) to merge or consolidate with or into any other corporation, or sell,
lease, license, or convey all or substantially all of its assets, or to
liquidate, dissolve or wind up; or (e) offer holders of registration rights the
opportunity to participate in an underwritten public offering of the company's
securities for cash, then, in connection with each such event, the Company shall
give the Holder (1) at least 20 days prior written notice of the date on which a
record will be taken for such dividend, distribution, or subscription rights
(and specifying the date on which the holders of Common Stock will be entitled
thereto) or in respect of the matters referred to in (c) and (d) above for
determining rights to vote, if any; (2) in the case of the matters referred to
in (c) and (d) above at least 20 days prior written notice of the date when the
same will take place (and specifying the date on which the holders of Common
Stock will be entitled to exchange their Common Stock for securities or other
property deliverable upon the occurrence of such event); and (3) in the case of
the matter referred to in (e) above, the same notice as is given to the holders
of such registration rights.

                  (b) INFORMATION RIGHTS. So long as the Holder holds this
Warrant and/or any of the Shares acquired on exercise of this Warrant, the
Company shall deliver to the Holder (a) promptly after mailing, copies of all
notices or other written communications to the stockholders of the Company, (b)
within ninety days after the end of each fiscal year of the Company, the annual
audited financial statements of the Company audited by independent public
accountants of recognized standing and (c) within forty-five days after the end
of each of the first three quarters of each fiscal year, the Company's
quarterly, unaudited financial statements.

                  (c) REGISTRATION UNDER SECURITIES ACT OF 1933. The Company
agrees that the Shares underlying this Warrant shall be "Registrable Securities"
under that certain Registration Rights Agreement, dated December 18, 1998, among
the Company, PICO and PHYSICIANS.

         8.       COMPLIANCE WITH ACT; TRANSFERABILITY AND NEGOTIABILITY OF
                  WARRANT; DISPOSITION OF SHARES.

                  (a) COMPLIANCE WITH ACT. The Holder, by acceptance hereof,
agrees that this Warrant and the Shares to be issued upon the exercise hereof
are being acquired solely for its own account and not as a nominee for any other
party and not with a view toward the resale or distribution thereof and that it
will not offer, sell or otherwise dispose of this Warrant or any Shares to be
issued upon the exercise hereof except under circumstances which will not result
in a violation of the Act. This Warrant and the Shares to be issued upon the
exercise hereof (unless registered under the Act) shall be imprinted with a
legend in substantially the following form:

         THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
         SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED,
         ASSIGNED OR HYPOTHECATED UNLESS THERE IS AN EFFECTIVE REGISTRATION
         STATEMENT UNDER SUCH ACT COVERING SUCH SECURITIES, THE SALE IS MADE IN
         ACCORDANCE WITH RULE 144 UNDER THE ACT, OR THE COMPANY RECEIVES AN
         OPINION OF COUNSEL FOR THE HOLDER OF THESE SECURITIES REASONABLY
         SATISFACTORY TO THE COMPANY, STATING THAT SUCH SALE, TRANSFER,
         ASSIGNMENT OR HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND
         PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT.

In addition, this Warrant and the Shares to be issued upon the exercise hereof
shall bear any legends required by the securities laws of any applicable states.

                  (b) TRANSFERABILITY AND NEGOTIABILITY OF WARRANT. This Warrant
may not be transferred or assigned in whole or in part without compliance with
all applicable federal and state securities laws by the transferor and the
transferee (including the delivery of investment representation letters and
legal opinions reasonably satisfactory to the Company, if reasonably requested
by the Company and the transfer is to a person other than a general partner or
affiliate of the initial Holder). Subject to the provisions of this Warrant with
respect to compliance with the Act, title to this Warrant may be transferred by
endorsement and delivery in the same manner as a negotiable instrument
transferable by endorsement and delivery. The Company shall act promptly to
record transfers of this Warrant on its books, but the Company may treat the
registered holder of this Warrant as the absolute owner of this Warrant for all
purposes, notwithstanding any notice to the contrary.

                  (c) DISPOSITION OF SHARES. With respect to any offer, sale,
transfer or other disposition of any Shares acquired pursuant to the exercise of
this Warrant prior to registration of such Shares, except for any such offer,
sale, transfer or other disposition of Shares to an affiliate of the initial
Holder, the Holder and each subsequent holder of this Warrant agrees to give
written notice to the Company prior thereto, describing briefly the manner
thereof, and if such transfer is not pursuant to Rule 144, a written opinion of
legal counsel for such holder, if requested by the Company, to the effect that
such offer, sale or other disposition may be effected without registration



<PAGE>   60


or qualification of such Shares. Notwithstanding the foregoing, such Shares may
be offered, sold or otherwise disposed of in accordance with Rule 144, provided
that the Company shall have been furnished with such information as the Company
may reasonably request to provide a reasonable assurance that the provisions of
Rule 144 have been satisfied. Each certificate representing the Shares thus
transferred (except a transfer pursuant to Rule 144) shall bear a restrictive
legend as to the applicable restrictions on transferability in order to insure
compliance with the Act, unless in the aforesaid opinion of legal counsel for
the holder, such legend is not required in order to insure compliance with the
Act.

         9. RIGHTS OF STOCKHOLDERS. No Holder shall be entitled to vote or
receive dividends or be deemed the holder of Shares or any other securities of
the Company which may at any time be issuable on the exercise of this Warrant
for any purpose, nor shall anything contained herein be construed to confer upon
the Holder, as such, any of the rights of a stockholder of the Company or any
right to vote for the election of directors or upon any matter submitted to
stockholders at any meeting thereof, or to give or withhold consent to any
corporate action (whether upon any recapitalization, issuance of stock,
reclassification of stock, consolidation, merger, transfer of assets or
otherwise) or, except as expressly required herein, to receive notice of
meetings, or to receive dividends or subscription rights or otherwise until this
Warrant shall have been exercised and the Shares issuable upon exercise hereof
shall have become deliverable, as provided herein.

         10. REPLACEMENT OF WARRANTS. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of an
indemnity agreement reasonably satisfactory in form and amount to the Company
or, in the case of mutilation, on surrender and cancellation of this Warrant,
the Company at its expense shall execute and deliver, in lieu of this Warrant, a
new warrant of like tenor.

         11. EXCHANGE OF WARRANT. Subject to the other provisions of this
Warrant, on surrender of this Warrant for exchange, and subject to the
provisions of this Warrant with respect to compliance with the Act, the Company
at its expense shall issue to or on the order of the Holder a new warrant or
warrants of like tenor, in the name of the Holder or as the Holder (on payment
by the Holder of any applicable transfer taxes) may direct, for the number of
Shares issuable upon exercise thereof.

         12. NOTICES. All notices and other communications from the Company to
the Holder, or vice versa, shall be deemed delivered and effective when given
personally or mailed by first-class registered or certified mail, postage
prepaid, at such address as may have been furnished to the Company or the
Holder, as the case may be, in writing by the Company or such Holder from time
to time.

         13. WAIVER. This Warrant and any term hereof may be changed, waived,
discharged or terminated only by an instrument in writing signed by the party
against which enforcement of such change, waiver, discharge or termination is
sought.

         14. GOVERNING LAW. This Warrant shall be governed by and construed in
accordance with the laws of the State of California.

         15. TITLES AND SUBTITLES; FORMS OF PRONOUNS. The titles of the Sections
and Subsections of this Warrant are for convenience only and are not to be
