into as of the 31st day of August,  1999,  by and  between  American  Physicians
Service Group, Inc., a Texas corporation ("APS") and Antonio Cavazos,  III, M.D.
(the "Shareholder").

                                R E C I T A L S:

         WHEREAS,  pursuant  to  that  certain  Asset  Purchase  Agreement  (the
"Purchase  Agreement")  dated April 1, 1998,  entered  into by  Shareholder  and
Syntera HealthCare Corporation,  a Texas corporation ("Syntera"),  and the other
contracts and agreements to which  Shareholder is a party as contemplated in the
Purchase  Agreement  (the Purchase  Agreement  and all such other  contracts and
agreements  are  hereinafter   referred  to  collectively  as  the  "Acquisition
Documents"),  Shareholder  acquired 70,000 shares (the "Syntera  Shares") of the
$0.001 par value per share common stock of Syntera; and

         WHEREAS,  in connection  with the execution of the Purchase  Agreement,
APS and  Shareholder  entered into that certain Share Exchange  Agreement  dated
April 1, 1998 (the "Original Agreement"); and

         WHEREAS,  APS and  Shareholder  have agreed to  terminate  the Original
Agreement upon the execution of this Agreement; and

<PAGE>

         WHEREAS,  at the  time of  execution  of this  Agreement,  Syntera  and
Shareholder  (in his capacity as a shareholder of Syntera) are  contemplating  a
proposed merger (the "Merger")  between Syntera and a subsidiary of FemPartners,
Inc., a Delaware corporation  ("FemPartners"),  pursuant to which Syntera may or
may not be the surviving corporation; and

         WHEREAS,  notwithstanding  the  Merger  and any effect it might have on
Shareholder's rights under the Original Agreement,  APS has agreed, on the terms
and subject to the conditions  hereof,  to exchange cash,  certain shares of its
$0.10 par value per share common stock ("APS Common"), or a combination thereof,
as determined by APS, for the Subject Shares (as hereinafter defined).

         NOW,  THEREFORE,  in  consideration of the foregoing and other good and
valuable  consideration,  the  receipt  and  sufficiency  of  which  are  hereby
acknowledged, the parties hereto agree as follows:

         1.  TERMINATION  OF SHARE  EXCHANGE  AGREEMENT.  Contemporaneous  with
and  contingent  only upon the execution  of this  Agreement,  the  Original
Agreement  is hereby  terminated  and  revoked,  and all  rights and privileges
of the parties thereto are nullified.

         2.  EFFECT  OF  MERGER.  In the event  the  Merger  occurs on or before
December 31, 1999,  the shares of  FemPartners  received by  Shareholder  in the
Merger,  in return for the Syntera shares (the "FemPartners  Shares"),  shall be
treated as Syntera Shares for all purposes hereunder.  As used herein,  "Subject
Shares" shall refer exclusively to the Syntera

<PAGE>

Shares,  unless the Merger occurs on or before December 31, 1999, in which event
"Subject Shares" shall,  after the Merger,  refer exclusively to the FemPartners
Shares.  As used  herein,  "Gross  Exchange  Value"  shall  mean the  amount  of
$350,000,  and such  amount  shall  not be  adjusted  in the  event of any stock
dividends,  stock splits, reverse stock splits or recapitalizations to which the
Subject Shares are subject after the date of this Agreement.

         3.   CONDITIONS TO EXCHANGE  RIGHT.  In addition to the other terms and
conditions  contained in this Agreement,  Shareholder  shall only be entitled to
exchange the Subject Shares if each of the following  conditions has been
satisfied:

                  (a) There shall not have been, on or before September 30, 2000
(the "Determination Date"), any registered public offering of shares of the same
class as the Subject Shares, or any other transaction or event pursuant to which
shares of the same class as the Subject Shares shall have become publicly traded
at a per share price (existing  immediately  after such public offering or other
transaction  or event)  which would yield an amount equal to or greater than the
Gross Exchange Value upon a sale of all of the Subject Shares at such price; and

                  (b) Shareholder  shall not be, or have been, at any time on or
prior to the date of the  closing  of any  exchange  of stock  pursuant  to this
Agreement (the "Closing Date"),  in breach of, or default under, this Agreement,
any of the  Acquisition  Documents  or any other  contract or agreement to which
Shareholder  and Syntera,  FemPartners,  APS and/or any of their  affiliates are
parties; and

<PAGE>

                  (c) At the Closing Date,  Shareholder  has all requisite legal
capacity  and  authority  to engage  in the  transactions  contemplated  by this
Agreement,  is the owner of all the Subject  Shares,  and the Subject Shares are
free of any and all liens, claims or encumbrances of any kind whatsoever; and

                  (d) If the Merger has not occurred on or prior to December 31,
1999, then on or before the Closing Date,  Syntera shall not be, or have been, a
party to any merger,  consolidation  or similar  transaction,  or agreement with
respect  thereto,  pursuant to which  Syntera was not or would not be, the named
surviving entity after such merger, consolidation or other transaction.

         4. EXCHANGE  NOTICE.  In the event all of the  conditions  described in
Section 1 are satisfied as of the Determination  Date and Shareholder  elects to
exercise its right to exchange its  Exchangeable  Subject Shares (as hereinafter
defined),  Shareholder  shall  provide  written  notice  thereof (the  "Exchange
Notice") to APS,  which  Exchange  Notice must be received by APS not later than
the date (the "Expiration Date") which is one hundred eighty (180) calendar days
after the  Determination  Date. In the event (i) any of the conditions  required
for an exchange to be permissible,  as described in Section 1 above,  fail to be
satisfied on or prior to the  Determination  Date, or (ii) any of the conditions
specified in  subsections  (b), (c) and (d) of Section 1 fail to be satisfied on
or prior to the Closing Date,  or (iii) APS fails to receive an Exchange  Notice
from Shareholder on or prior to the Expiration Date; then, in any such case, all
of Shareholder's  rights under this Agreement shall automatically  terminate and
be of no further force or effect whatsoever.

<PAGE>

         5.  SHARE EXCHANGE.

         (a) Shareholder's  right to exchange its Subject Shares hereunder shall
apply as to all, but not less than all, of the Subject Shares which are eligible
for exchange as described in this  subparagraph  (a).  Assuming  Shareholder has
complied with all of the  conditions  allowing for an exchange  pursuant to this
Agreement,  42.9% of the  Subject  Shares  shall be  eligible  for  exchange  as
provided in this Agreement;  and the remaining 57.1% of the Subject Shares, or a
portion  thereof,  will only be eligible for an exchange  hereunder in the event
there is  consummation  of a  transaction  between  Syntera or its  successor in
interest and one or more  physicians  (or their  professional  associations)  in
Bexar County, Texas, save and except for those physicians set forth on Exhibit A
attached  hereto and  incorporated  herein for all  purposes,  whereby each such
physician  not set forth on Exhibit A enters  into,  on or before March 31, 2000
(the "Vesting Cutoff Date"),  a binding and  enforceable  agreement with Syntera
(or its successor in interest) of the type and nature  ordinarily relied upon by
Syntera (or its successor in interest) in its dealings with  physicians.  In the
event  that there is a  consummation  of any such  transaction  on or before the
Vesting  Cutoff Date,  then the portion of the 57.1% of the Subject Shares which
will be eligible for exchange  pursuant to this Agreement  (assuming  compliance
with all other conditions  provided for in this Agreement) will be determined by
multiplying   7.14%  by  the  number  of  physicians  in  Bexar  County,   Texas
consummating such  transactions,  save and except for those physicians set forth
on Exhibit A.

<PAGE>

                  Notwithstanding  the  above  or any  other  provision  in this
Agreement,  (i) the Shareholder shall not benefit from, and the above provisions
shall not apply to, any such  transaction  between  Syntera or its  successor in
interest and any of the  physicians  set forth on Exhibit A and (ii) any portion
of the 51.7% of the Subject Shares which has not, as of the Vesting Cutoff Date,
become eligible for exchange hereunder  (pursuant to the above provisions) shall
no longer be eligible for exchange under any circumstances.

         (b) In the event  Shareholder  has complied with all of the  conditions
allowing  for an exchange  pursuant to this  Agreement,  the closing of any such
exchange (the "Closing") shall occur at the offices of APS in Austin,  Texas, on
such day and at such time as the parties  hereto may mutually  agree upon, or in
the failure to so agree, at 10:00 a.m. Austin,  Texas time on the first business
day that falls thirty (30) days after the later of (x) the Expiration  Date, (y)
if a Lock-Up Period (as  hereinafter  defined) is imposed  pursuant to Section 6
hereof,  the day on which such Lock-Up Period ends, or (z) if a Market Delay (as
hereinafter  defined) is imposed  pursuant to Section  5(c)  hereof,  the day on
which such  Market  Delay  ends.  The  maximum  number of Subject  Shares  which
Shareholder  has the right to  exchange  pursuant  to  subparagraph  (a) of this
Section are hereinafter referred to as the "Exchangeable Subject Shares." At the
Closing, Shareholder shall be entitled to receive either:

                  (i) such shares of APS Common as is determined by dividing the
Gross Exchange Value by the average of the "bid" and "ask" prices for APS Common
as quoted by the National  Association of Securities Dealers Automated Quotation
System  at the  close of  trading  on each of the last  five (5)  business  days
immediately preceding the Closing Date; or

<PAGE>

                  (ii)     cash or immediately available funds in the amount of
the Gross Exchange Value; or

                  (iii) any  combination  thereof (as  determined  by APS in its
sole discretion), equal in aggregate value to the Gross Exchange Value.

         (c) In the event APS  elects to  satisfy  its  obligations  under  this
Section 5 in whole or in part with the issuance to  Shareholder of shares of APS
Common,  APS shall  have the  right,  as long as a Lock-Up  Period  has not been
imposed  pursuant to Section 6 hereof,  to delay the  issuance of such shares of
APS Common for up to ninety (90) calendar days (the "Market Delay"), if, in APS'
sole discretion, an issuance of shares of APS Common pursuant to this Agreement,
or in combination with any similar agreement or agreements, would depreciate the
market value of the APS Common.

         (d) At the Closing,  Shareholder shall tender its share  certificate(s)
for all of the Exchangeable  Subject Shares, duly endorsed in blank, to APS, and
shall also provide APS with an executed blank stock power, in form and substance
reasonably acceptable to APS, wherein Shareholder represents and warrants to APS
(i) that  Shareholder has all necessary  legal capacity,  power and authority to
engage in the transactions  contemplated  hereby, and (ii) that Shareholder owns
all  interests  in  and  to  the  Exchangeable   Subject  Shares  and  that  the
Exchangeable  Subject Shares are being  transferred to APS free and clear of all
liens, claims or encumbrances of any kind whatsoever.

<PAGE>

         (e) The parties  acknowledge and agree that Shareholder shall receive a
whole number of shares of APS Common only, and that any fractional share amounts
resulting from the foregoing  exchange  calculation shall be rounded up or down,
as the  case  may be,  to the next  whole  number  of  shares.  At the  Closing,
Shareholder shall receive a share certificate or certificates for all its shares
of APS Common.

         6.  TRANSFERABILITY.  APS will have registered any shares of APS Common
exchanged   hereunder  with  the  Securities   and  Exchange   Commission   (the
"Commission"),  and made such  other  filings  and  taken  such  other  steps as
necessary,  so that Shareholder may immediately sell, or otherwise convey,  such
shares of APS Common without  restriction  (except as otherwise provided below).
Shareholder agrees to cooperate fully and in all respects with APS in connection
with any such  registration,  whether such  cooperation  is requested  before or
after the  Determination  Date.  Failure  of  Shareholder  to  cooperate  fully,
including  without   limitation,   promptly   providing  complete  and  accurate
information  to APS,  in  connection  with the  registration  of any APS  Common
shares, whether such cooperation and/or information is requested before or after
the  Determination  Date or before or after  Shareholder  delivers  any Exchange
Notice, shall automatically terminate Shareholder's rights under this Agreement.
Notwithstanding anything contained herein to the contrary, in the event that APS
is in the process,  either at the Closing Date or at the Determination  Date, of
registering  and/or  selling  any of its  capital  stock in or  pursuant  to any
underwritten  public offering,  upon the written request of the lead underwriter
involved therein,  Shareholder  agrees,  and shall then agree in writing in form
and substance  reasonably  acceptable  to APS, to not sell,  attempt to sell, or
solicit or accept any

<PAGE>

offers to sell or  otherwise  convey,  any of its  shares of APS Common for such
period of time (not to exceed one hundred eighty (180) days) as may be requested
by such lead underwriter (the "Lock-Up Period").

         7.  MISCELLANEOUS.

                  (a) FEES AND EXPENSES.  Except as otherwise  provided  herein,
each  party  hereto  agrees  to bear all fees and  expenses  (including  without
limitation  all fees and expenses for its legal counsel and any  accountants  or
other  professional  advisors)  incurred  in  connection  with the  transactions
contemplated hereby.

                  (b) GOVERNING LAW AND VENUE.  This Agreement shall be governed

ineffective).  Venue for any action  relating to this Agreement  shall be proper

                  (c)    COUNTERPARTS.    This   Agreement   may   be   executed
simultaneously  in one or more  counterparts,  each of which  shall be deemed an
original,  and  all  of  which  together  shall  constitute  one  and  the  same
instrument.

         5.   SHARE EXCHANGE.

         (a) Shareholder's  right to exchange its Subject Shares hereunder shall

allowing  for an exchange  pursuant to this  Agreement,  the closing of any such
exchange (the "Closing") shall occur at the offices of APS in Austin,  Texas, on
such day and at such time as the parties  hereto may mutually  agree upon, or in
the failure to so agree, at 10:00 a.m. Austin,  Texas time on the first business
day that falls thirty (30) days after the later of (x) the Expiration  Date, (y)
if a Lock-Up Period (as  hereinafter  defined) is imposed  pursuant to Section 6
hereof,  the day on which such Lock-Up Period ends, or (z) if a Market Delay (as
hereinafter  defined) is imposed  pursuant to Section  5(c)  hereof,  the day on
which such  Market  Delay  ends.  The  maximum  number of Subject  Shares  which
Shareholder  has the right to  exchange  pursuant  to  subparagraph  (a) of this

the Gross Exchange Value; or

                  (iii) any  combination  thereof (as  determined  by APS in its
sole discretion), equal in aggregate value to the Gross Exchange Value.

         (c) In the event APS  elects to  satisfy  its  obligations  under  this
Section 5 in whole or in part with the issuance to  Shareholder of shares of APS
Common,  APS shall  have the  right,  as long as a Lock-Up  Period  has not been
imposed  pursuant to Section 6 hereof,  to delay the  issuance of such shares of
APS Common for up to ninety (90) calendar days (the "Market Delay"), if, in APS'
sole discretion, an issuance of shares of APS Common pursuant to this Agreement,
or in combination with any similar agreement or agreements, would depreciate the
market value of the APS Common.

         (d) At the Closing,  Shareholder shall tender its share  certificate(s)
for all of the Exchangeable  Subject Shares, duly endorsed in blank, to APS, and
shall also provide APS with an executed blank stock power, in form and substance
reasonably acceptable to APS, wherein Shareholder represents and warrants to APS
(i) that  Shareholder has all necessary  legal capacity,  power and authority to
engage in the transactions  contemplated  hereby, and (ii) that Shareholder owns
all  interests  in  and  to  the  Exchangeable   Subject  Shares  and  that  the
Exchangeable Subject

<PAGE>

Shares  are  being  transferred  to APS free and clear of all  liens,  claims or
encumbrances of any kind whatsoever.

         (e) The parties  acknowledge and agree that Shareholder shall receive a
whole number of shares of APS Common only, and that any fractional share amounts
resulting from the foregoing  exchange  calculation shall be rounded up or down,
as the  case  may be,  to the next  whole  number  of  shares.  At the  Closing,
Shareholder shall receive a share certificate or certificates for all its shares
of APS Common.

         6.  TRANSFERABILITY.  APS will have registered any shares of APS Common
exchanged   hereunder  with  the  Securities   and  Exchange   Commission   (the
"Commission"),  and made such  other  filings  and  taken  such  other  steps as
necessary,  so that Shareholder may immediately sell, or otherwise convey,  such
shares of APS Common without  restriction  (except as otherwise provided below).
Shareholder agrees to cooperate fully and in all respects with APS in connection
with any such  registration,  whether such  cooperation  is requested  before or
after the  Determination  Date.  Failure  of  Shareholder  to  cooperate  fully,
including  without   limitation,   promptly   providing  complete  and  accurate
information  to APS,  in  connection  with the  registration  of any APS  Common
shares, whether such cooperation and/or information is requested before or after
the  Determination  Date or before or after  Shareholder  delivers  any Exchange
Notice, shall automatically terminate Shareholder's rights under this Agreement.
Notwithstanding anything contained herein to the contrary, in the event that APS
is in the process,  either at the Closing Date or at the Determination  Date, of
registering  and/or  selling  any of its  capital  stock in or  pursuant  to any
underwritten public offering, upon the written request of the

<PAGE>

lead underwriter  involved therein,  Shareholder agrees, and shall then agree in
writing in form and substance reasonably acceptable to APS, to not sell, attempt
to sell, or solicit or accept any offers to sell or otherwise convey, any of its
shares of APS Common for such period of time (not to exceed one  hundred  eighty
(180) days) as may be requested by such lead underwriter (the "Lock-Up Period").

         7.   MISCELLANEOUS.

                  (a) FEES AND EXPENSES.  Except as otherwise  provided  herein,
each  party  hereto  agrees  to bear all fees and  expenses  (including  without
limitation  all fees and expenses for its legal counsel and any  accountants  or
other  professional  advisors)  incurred  in  connection  with the  transactions
contemplated hereby.

                  (b) GOVERNING LAW AND VENUE.  This Agreement shall be governed
by, and  construed  and enforced in  accordance  with,  the laws of the State of
Texas  (except  the  laws  of  Texas  that  would  render  such  choice  of  law
ineffective).  Venue for any action  relating to this Agreement  shall be proper
only in Texas.

                  (c)    COUNTERPARTS.    This   Agreement   may   be   executed
simultaneously  in one or more  counterparts,  each of which  shall be deemed an
original,  and  all  of  which  together  shall  constitute  one  and  the  same
instrument.

parties hereto and

hereunder,  without the express prior written  consent of all parties  hereto in
