corporation  ("SHCR"),   KENNETH  TRIMMER,  M.D.,  P.A.,  a  Texas  professional
association (the "Company"),  KENNETH TRIMMER, M.D., the sole shareholder of the
Company (the "Shareholder"), and GILBERT DROZDOW, M.D. ("Trustee").

R E C I T A L S

     1. Simultaneously with the execution and delivery of this Agreement,  SHCR,
the Shareholder  and the Company have entered into a Purchase Option  Agreement,
dated March 4, 1998.

     2. In accordance with Section 4 of that certain Purchase Option  Agreement,
the parties have agreed to execute this  Agreement for the purposes of obtaining
stable and  experienced  management  for the Company,  preserving  the Company's
value and  continuing  the  Company's  operations  prior to the  exercise of the
option under the Purchase Option Agreement.

     NOW, THEREFORE, for and in consideration of the mutual agreements set forth
below, the parties agree as follows:

I.     TRUSTEE.

     A.     Appointment.  Gilbert Drozdow, M.D. is hereby appointed the
trustee under this Agreement ("Trustee").  The Trustee acknowledges that he is
an individual who is licensed to practice medicine in the State of Texas (an
"Eligible Person").

     B, Successor Trustee. SHCR may, in its sole discretion, replace the Trustee
with another Eligible Person at any time upon ten (10) days prior written notice
to the  Shareholder.  If the  Trustee  shall  resign,  die,  become  permanently
disabled,  or be unable or refuse for any  reason to act as  Trustee  hereunder,
SHCR  shall  have the  right to  select,  in its sole  discretion,  a  successor
Trustee,  provided,  however,  that such successor  Trustee shall be an Eligible
Person.  Upon SHCR's  designation  of a replacement  or successor  Trustee,  the
Trustee or his  personal  representative  shall  deliver to the  replacement  or
successor  Trustee all share  certificates  representing  shares  deposited with
Trustee under this Agreement, with such share certificates endorsed in blank and
accompanied  by  instruments  of transfer  that will enable the  replacement  or
successor  Trustee  to cause  the  shares to be  transferred  to the name of the
replacement or successor Trustee.

II.     VOTING TRUST.

     A. Exchange of Shares for Voting Trust  Certificates.  Simultaneously  with
the execution of this Agreement,  but subject to the restrictions on transfer of
the common stock, par value $.10 per share,  (the "Common Stock") of the Company
by  law,  rule,   regulations,   judicial   interpretation   or  other  official
governmental  interpretation,  the  Shareholder  shall assign and  deliver,  for
deposit with the  Trustee,  share  certificates  for all of the shares of Common
Stock held or owned by the  Shareholder  (which  number is One  Thousand  Shares
(1000),  and immediately upon receipt by Shareholder,  Shareholder  shall assign
and deliver,  for deposit with  Trustee,  share  certificates  for all shares of
Common Stock that are  subsequently  held or owned by Shareholder.  All of these
share  certificates  shall be  endorsed  in blank  and shall be  accompanied  by
instruments  of  transfer  that will  enable  Trustee  to cause the shares to be
transferred in the name of Trustee.


     Trustee  will cause such shares of Common  Stock to be  transferred  to the
Trustee,  on the  books  of the  Company,  and will  issue  and  deliver  to the
Shareholder  Voting Trust  Certificates for the number of shares of Common Stock
transferred to the Trustee.

     B.     Form of Voting Trust Certificates. The Voting Trust Certificates
shall be in the form attached hereto as Exhibit "A."

     C.  Transfers  and Record  Owner.  The Voting Trust  Certificates  shall be
transferable, subject to applicable laws and this Agreement, on the books of the
Trustee by the Shareholder,  either in person or by attorney duly authorized and
upon  surrender  thereof.  Until  so  transferred  the  Trustee  may  treat  the
registered holder as owner thereof for all purposes whatsoever. Every transferee
of a Voting Trust Certificate shall by the acceptance  thereof become a party to
this  Agreement  with the same force and effect as if he or she had signed  this
Agreement,  and shall be embraced  within the  meaning of the term Voting  Trust
Certificate  Holder  whenever  used  herein.  Share  certificates  shall  not be
deliverable  hereunder  without  the  surrender  of  Voting  Trust  Certificates
representing an equivalent  number of shares.  The transfer books of the Trustee
may, in his  discretion,  be closed and  transfers of Voting Trust  Certificates
thereon may be  suspended  from time to time for such  reasonable  period as the
Trustee may determine. The Trustee may, at any time, appoint a registrar for the
Voting Trust Certificates,  and may provide that Voting Trust Certificates shall
not be valid unless registered and countersigned by such registrar.

     D. Voting by Trustee.  During the period of this Voting Trust,  the Trustee
shall possess the exclusive right, in his unrestricted  discretion,  to vote the
shares and to exercise the rights set forth in Section II.H. of this  Agreement.
If more than one person is serving as the  Trustee,  all  actions to be taken on
any  questions  shall be  determined  by the vote or  agreement of a majority of
those serving as the Trustee.

     E.  Subscriptions  to New Shares or  Securities.  In case the Company shall
offer  any  of  its  shares  or  other   securities  to  its   shareholders  for
subscription,  then in such case upon receiving from the  Shareholder,  prior to
the time  limited by the  Company for  subscription  and  payment,  a request to
subscribe in his behalf,  and the money  required to pay for a stated  amount of
such shares or other  securities  the Trustee  will make such  subscription  and
payment,  and upon  receiving from the Company the share  certificates  or other
securities so subscribed  for, will issue one or more Voting Trust  Certificates
in respect thereof to the Shareholder. The Trustee shall not, in any event, with
respect to any  dividend  in shares or shares  subscribed  for,  be  required to
deliver certificates  representing  fractional parts of a share, but may in lieu
thereof  deliver,   in  respect  of  fractional   interest,   fractional  script
certificates  in such form and upon such terms and conditions as the Trustee may
in his discretion determine.

     F.  Termination  of Trust.  This Voting  Trust shall  terminate on March 4,
2097,  or if a court of  competent  jurisdiction  would  render  this  Agreement
unenforceable or invalid due to the termination  date, then the termination date
shall  automatically  be reduced to a date which  would cure the  invalidity  or
unenforceability.  The  trust  created  by this  Agreement  is  coupled  with an
interest and is expressly  declared to be irrevocable to the extent permitted by
law, except as it may be terminated pursuant to this Section.



                                       2



     Upon  termination of this Agreement,  the  Shareholder  shall surrender his
Voting Trust  Certificates to the Trustee,  and the Trustee shall deliver to the
Shareholder  certificates  representing  shares of the Company properly endorsed
for transfer, equivalent to the amount of shares represented by the Voting Trust
Certificates surrendered; provided, however, that the Trustee shall be obligated
to deliver  such  shares only if any and all liens  against  same have been duly
released.

     G. Trustee as Shareholder or Employee.  The Trustee,  and his successor(s),
may be a party to this Agreement as a Voting Trust  Certificate  Holder,  and to
the  extent of the shares  deposited  by him and he is  qualified  by law to own
shares in the  Company,  he shall be entitled in all respects to the same rights
and benefits as other Voting Trust  Certificate  Holders.  The Trustee may serve
the  Company or any of its  subsidiaries  as a director  or an officer or in any
other  capacity,   and  may  receive  compensation  from  the  Company  or  such
subsidiaries for such services.

     H. Rights and Powers of Trustee. The Trustee shall possess and be entitled,
subject to the provisions hereof and law, in his discretion, to exercise all the
rights and powers of the beneficial  owners of all shares  deposited  hereunder,
including, but without limitation, the right to receive dividends on such shares
(for  the  benefit  of SHCR)  and the  right to vote,  consent  in  writing,  or
otherwise act with respect to any corporate or shareholders' action, to increase
or reduce the stated  capital of the Company,  to classify or reclassify  any of
the shares as now or hereafter  authorized  into  preferred or common  shares or
other  classes of shares,  to amend the Articles of  Association  or Bylaws,  to
merge or consolidate the Company with other  Companies,  to sell all or any part
of the assets,  or for any other  lawful  corporate  act or purpose  that may be
undertaken by shareholders of the Company, it being expressly stipulated that no
voting right shall pass to others by or under the Voting Trust  Certificates  or
by or under this Agreement (with the exception of any successor Trustee named in
accordance  with  Article I  hereof),  or by or under any  agreement  express or
implied;  provided,  however,  that Trustee shall have no rights to transfer the
shares except pursuant to a consolidation or merger.

     In case the Trustee  shall vote or  otherwise  act in respect of the shares
deposited  hereunder  so as to effect a  consolidation  or merger of the Company
with and into  another  professional  association  or other  legal  entity,  the
Trustee may in  connection  with such  consolidation  or merger  surrender  such
shares and receive in lieu thereof and in exchange  therefor the shares issuable
therefore in such merger or  consolidation,  and may hold the shares so received
in  place  of  the  shares  deposited  hereunder.  Thereafter,  the  rights  and
obligations  of the  Trustee  and of the  Shareholder  with  respect  to  shares
deposited  hereunder shall for all purposes be treated as applying to the shares
so  received.  Upon demand of the Trustee to the  Shareholder,  the  Shareholder
shall surrender his Voting Trust  Certificates to the Trustee,  and shall accept
in lieu thereof one or more new Voting Trust  Certificates  in a form similar to
that set forth in Exhibit "A" of this Agreement,  but modified so as to describe
expressly the interest then  represented  by the Voting Trust  Certificate.  Any
transfer tax or other charges  payable in respect of any such exchange  shall be
paid by the Trustee.

     The Trustee is also  authorized to become a party to or prosecute or defend
or intervene in any suits or legal proceedings  involving the shares held in the
Voting Trust.

     I. Compensation and Expenses of Trustee.  The Trustee is not to receive any
compensation  for its services  hereunder.  The Trustee may employ counsel,  and
such other assistance as may be convenient, in the performance of his functions.
The Trustee  shall be  responsible  for any and all  expenses  incurred by it in
connection  with or arising out of this Agreement or the discharge of its duties
hereunder.

     J.  Meetings of Voting  Trust  Certificate  Holders.  In the event that the
Trustee  shall desire to  ascertain  the views of SHCR or the  Shareholder  with
respect  to any  action  or thing  done or  proposed  to be done by it or by the
Company,  the Trustee may for such  purpose call a meeting of such holders to be
held in Dallas,  Texas. Such notice shall set forth the time, place, and purpose
of the  meeting and notice  thereof  shall be  delivered  at least five (5) days
before  the date of such  meeting  to the  Shareholder.  No  action  at any such
meeting shall operate to modify the express  provisions of this  Agreement or in
any way limit the  powers  and  discretion  of the  Trustee  as  defined by this
Agreement.

                                       3


     K. Notices from Company. Copies of notices, reports,  statements, and other
communications  directed to the  Trustee  from the  Company  shall be  forwarded
immediately to the Shareholder, with the postmarked date and the date of receipt
endorsed on the communication.

     L. Liability of Trustee No Trustee shall be liable for the acts or defaults
of any other  Trustee or for the acts or defaults of an agent or  representative
of any other  Trustee.  Each Trustee shall be free from liability in acting upon
any paper, document, or signature believed by him to be genuine and to have been
signed by the proper party.  No Trustee shall be liable under this  Agreement or
otherwise for any action of any kind taken or omitted by him  hereunder,  or for
any error of judgment,  mistake of law, or other mistake or  negligence,  except
for Trustee's own gross negligence or willful misconduct.

III.     MISCELLANEOUS.

forth above and terminate as set forth in Section II.F. above.

     B.     Amendment.  This Agreement may be amended by the written agreement

any such written agreement by and among SHCR, the Company and the Shareholder.

     C. Addition of Other Parties.  The execution by additional  parties to this
Agreement,  after the effective date of this Agreement, is permissible only with
the prior approval of Trustee and the Shareholder;  provided,  however, that the
Shareholder  shall not withhold such approval of any designee of SHCR designated
under that certain Purchase Option Agreement. No such approval shall be required
for parties added as a result of any transfers of shares already subject to this
Agreement.
