            AMERICAN PHYSICIANS SERVICE GROUP, INC., AND SUBSIDIARIES

                           ANNUAL REPORT ON FORM 10-K

                   FOR THE FISCAL YEAR ENDED DECEMBER 31, 1999

                                     PART I

ITEM 1.  BUSINESS

GENERAL

      American  Physicians  Service  Group,  Inc. (the  "Company"),  through its
subsidiaries,  provides services that include management services to malpractice
insurance  companies,  and brokerage and investment  services to individuals and
institutions.  In 1999 the Company entered into the environmental consulting and
engineering  services  business.  The  Company  also  owns  space in the  office
building,  which serves as its headquarters.  Through its real estate subsidiary
it leases space that is surplus to its needs.

      The Company was  organized  in October 1974 under the laws of the State of
Texas. The Company  maintains its principal  executive office at 1301 Capital of
Texas Highway,  Suite C-300,  Austin,  Texas 78746,  and its telephone number is
(512) 328-0888.  Unless the context otherwise requires, all references herein to
the  "Company"  shall mean  American  Physicians  Service  Group,  Inc.  and its
subsidiaries.

      Financial information about the Company's industry segments is disclosed
in Note 14 to the accompanying Consolidated Financial Statements in Appendix A.

FINANCIAL SERVICES

      APS Investment Services, Inc. ("Investment  Services"),  is a wholly-owned
subsidiary of the Company.  Through its subsidiaries,  APS Financial Corporation
("APS  Financial"),   and  APS  Asset  Management,   Inc.  (Asset  Management"),
Investment  Services  provides  investment and investment  advisory  services to
institutions  and individuals  throughout the United States.  Revenues from this
segment  were  57%,  60% and 44% of  Company  revenues  in 1999,  1998 and 1997,
respectively.

      APS Financial,  a fully  licensed  broker/dealer,  provides  brokerage and
investment  services  primarily to  institutional  and high net worth individual
clients. APS Financial also provides portfolio accounting,  analysis,  and other
services, to insurance companies, banks, and public funds. APS Financial has its
main office in Austin, with a branch office in Houston.

      APS  Financial  is a member  of the  National  Association  of  Securities
Dealers, Inc. ("NASD"), the Securities Investor Protection Corporation ("SIPC"),
the Securities Industry Association, and, in addition, is licensed in 45 states.

      Commissions  are charged on both  exchange  and  over-the-counter  ("OTC")
transactions in accordance with industry  practice.  When OTC  transactions  are
executed  by APS  Financial  as a dealer,  APS  Financial  receives,  in lieu of
commissions, markups or markdowns.

                                        1

<PAGE>

      Every registered  broker/dealer  doing business with the public is subject
to stringent rules with respect to net capital  requirements  promulgated by the
SEC.  These rules,  which are designed to measure the  financial  soundness  and
liquidity of broker dealers, specify minimum net capital requirements. Since the
Company is not itself a  registered  broker  dealer,  it is not subject to these
rules.  However,  APS  Financial  is subject  to these  rules.  Compliance  with
applicable net capital requirements could limit operations of APS Financial such
as trading activities that require the use of significant amounts of capital and
limit  its  ability  to  pay  dividends.  A  significant  operating  loss  or an
extraordinary  charge against net capital could adversely  affect the ability of
APS  Financial  to expand or even  maintain its present  levels of business.  At
February  29,  2000,  APS  Financial  was in  compliance  with  all net  capital
requirements.

      APS Financial clears its transactions through Southwest  Securities,  Inc.
("Southwest")  on a fully disclosed  basis.  Southwest also processes orders and
floor reports,  matches trades, transmits execution reports to APS Financial and
records all data  pertinent to trades.  APS Financial pays Southwest a fee based
on the number and type of transactions performed by Southwest.

      Asset  Management,   a  Registered  Investment  Adviser,  was  formed  and
registered with the Securities and Exchange Commission in 1998. Asset Management
was  organized to manage fixed income and equity  assets for  institutional  and
individual  clients on a fee  basis.  Asset  Management's  mission is to provide
clients  with  investment   results  within  specific   client-determined   risk
parameters.

INSURANCE SERVICES

      APS  Insurance  Services,  Inc.,  ("Insurance  Services"),  an  80%  owned
subsidiary of the Company through its  wholly-owned  subsidiaries APS Facilities
Management,   Inc.  ("FMI")  and  American  Physicians  Insurance  Agency,  Inc.
("Agency"),  provides  management  and agency  services  to medical  malpractice
insurance companies.  Revenues from this segment contributed 24%, 34% and 48% of
Company revenues in 1999, 1998 and 1997, respectively.  Substantially all of the
revenue was attributable to American Physicians  Insurance Exchange ("APIE"),  a
reciprocal insurance exchange managed by FMI. A reciprocal insurance exchange is
an  organization  which sells  insurance  only to its  subscribers,  who pay, in
addition to their annual  insurance  premiums,  a contribution to the exchange's
surplus.  Such exchanges generally have no paid employees but instead enter into
a  contract  with  an  "attorney-in-fact",  that  provides  all  management  and
administrative  services for the exchange. As the attorney-in-fact for APIE, FMI
receives a percentage  of the earned  premiums of APIE,  as well as a portion of
APIE's  profits.  The amount of these  premiums  can be  adversely  affected  by
competition.  Substantial  underwriting losses or investment performance,  which
might result in a curtailment  or cessation of  operations  by APIE,  would also
adversely affect FMI's revenue. To limit possible underwriting losses or adverse
investment performance,  APIE currently reinsures its risk in excess of $250,000
per medical incident.  APIE offers medical professional  liability insurance for
physicians in Texas and Arkansas.  FMI's assets are not subject to any insurance
claims by policyholders of APIE.

                                        2

<PAGE>

      FMI organized APIE and has been its exclusive  manager since its inception
in 1975. The management  agreement  between FMI and APIE basically  provides for
full  management  by FMI of the  affairs of APIE under the  direction  of APIE's
physician Board of Directors.  Subject to the direction of this Board, FMI sells
and issues  policies,  investigates,  settles and defends claims,  and otherwise
manages APIE's  affairs.  In  consideration  for  performing  its services,  FMI
receives a percentage  fee based on APIE's earned  premiums  (before  payment of
reinsurance premiums), as well as a portion of APIE's profits. FMI pays salaries
and  personnel  related  expenses,   rent  and  office  operations  costs,  data
processing costs and many other operating  expenses of APIE. APIE is responsible
for the payment of all claims, claims expenses, peer review expenses, directors'
fees and expenses, legal, actuarial and auditing expenses, its taxes and certain
other specific expenses. Under the management agreement,  FMI's authority to act
as manager of APIE is  automatically  renewed each year unless a majority of the
subscribers to APIE elect to terminate the management  agreement by reason of an
adjudication that FMI has been grossly negligent, has acted in bad faith or with
fraudulent  intent  or has  committed  willful  misfeasance  in  its  management
activities.  Termination  of FMI's  management  agreement with APIE would have a
material adverse effect on the Company.

      During 1997, FPIC Insurance Group, Inc. ("FPIC"), purchased a 20% interest
in Insurance  Services  from the Company.  In  conjunction  with that  purchase,
FPIC's  subsidiary,   Florida  Physicians  Insurance  Company,   Inc.  ("Florida
Physicians"),  entered into  agreements with Agency and APIE granting Agency the
exclusive  right to market  Florida  Physician's  policies in Texas.  Agency has
sales,  marketing,  underwriting  and  claims  handling  authority  for  Florida
Physicians  in  Texas  and  receives  commissions  for  such  services.  Florida
Physicians  also entered into a  reinsurance  agreement  with APIE in which APIE
reinsures  substantially all of Florida  Physicians' risk in Texas under medical
professional  liability  policies  issued or renewed by  Florida  Physicians  on
behalf of Texas health care providers after March 27, 1997. The Company had also
granted  FPIC an option,  exercisable  at any time during  1999,  to purchase an
additional 35% interest in Insurance Services from the Company.  This option has
expired.

      APIE is  authorized  to do business  in the states of Texas and  Arkansas.
Florida Physicians is a stock company licensed in several states. Both companies
specialize in writing medical  professional  liability insurance for health care
providers. The insurance written in Texas is primarily through purchasing groups
and is not  subject to certain  rate and policy form  regulations  issued by the
Texas  Department of Insurance.  Applicants for insurance  coverage are reviewed
based  on the  nature  of  their  practices,  prior  claims  records  and  other
underwriting criteria. APIE is one of the largest medical professional liability
insurance  companies  in the  State  of  Texas.  APIE is the  only  professional
liability  insurance  company  based  in  Texas  that  is  wholly-owned  by  its
subscriber physicians.

      Florida  Physicians,  together  with its  affiliates,  insures  over 6,800
physicians nationwide. Florida Physicians is rated A- (Excellent) by AM Best.

                                        3

<PAGE>

      Generally, medical professional liability insurance is offered on either a
"claims made" basis or an  "occurrence"  basis.  "Claims made"  policies  insure
physicians  only against  claims that occur and are  reported  during the period
covered by the policy.  "Occurrence"  policies insure physicians  against claims
based on  occurrences  during the policy period  regardless of when the claim is
actually made. APIE and Florida  Physicians offer only a "claims made" policy in
Texas  and  Arkansas,   but  provide  for  an  extended  reporting  option  upon
termination of coverage.  APIE and Florida Physicians reinsure 100% of all Texas
and Arkansas coverage per medical incident between $250,000 and the policy limit
$1,000,000,  primarily  through  certain  domestic and  international  insurance
companies.

      The following table presents  selected  financial and other data for APIE.
The management  agreement with FMI obligates APIE to pay management  fees to FMI
based on APIE's earned premiums before payment of reinsurance premiums.  The fee
percentage is 13.5% with the  provision  that any profits of APIE will be shared
equally with FMI so long as the total reimbursement (fees and profit sharing) do
not exceed a cap based on premium levels.  In 1999,  1998, 1997, 1996, and 1995,
management  fees  attributable  to profit  sharing  were  $329,000,  $1,750,000,
$1,961,000,  $1,191,000,  and  $700,000,  respectively.  The decrease in 1999 is
primarily  due to an overall  increase in  competition  in medical  professional
liability  insurance  in Texas as well as a  continued  trend of  rising  claims
against the insureds.

CONSULTING

      On October 31, 1996,  the Company  invested  $3,300,000 in common stock of
Exsorbet Industries, Inc. ("Exsorbet") (NASDAQ:EXSO) with a put option. Exsorbet
was a diversified  environmental and technical services company. On November 26,
1996,  the Company  exercised  its put in exchange  for a note  receivable  from
Exsorbet. The note was secured by the shares that were subject to the put option
plus all the  stock  and  substantially  all of the  assets  of a  wholly  owned
subsidiary  of Exsorbet.  Subsequently,  Exsorbet  became known as  Consolidated
Eco-Systems, Inc. ("Con-Eco").

      On June 17, 1998 the Company filed suit against Con-Eco, and its directors
and  officers  alleging  breach of  contract,  negligent  misrepresentation  and
conspiracy.  In  February,  1999 the Company  settled this  litigation  with the
directors and officers of Con-Eco.  The Company recovered  $950,000 for the full
release of all claims against the directors of Con-Eco.

      In April,  1999,  the Company's  wholly owned  subsidiary,  APS Consulting
("APS Consulting"),  acquired the business of Eco-Systems, Inc. ("Eco-Systems"),
a subsidiary of Con-Eco, in connection with a debt restructuring  agreement with
Con-Eco. Under the terms of the restructuring  agreement,  Con-Eco had the right
to purchase  back the  business  of  Eco-Systems  for a nominal  amount upon the
occurrence  of certain  conditions.  Accordingly,  the Company did not initially
consolidate the operations of APS Consulting. In addition, the Company dismissed
its  lawsuit  against  Con-Eco,  but  retained  the  right  to  reinstitute  the
litigation at a later date.

      Subsequently,  the Company concluded that it was not probable that Con-Eco
would  exercise its option to reacquire  the stock and,  effective  September 1,
1999,  the Company began  consolidating  APS  Consulting.  The  acquisition  was
recorded using the purchase method of accounting. In addition, the Company wrote
off the remaining balance of the note due from Con-Eco. During the twelve months
ended  December  31, 1999 the Company  wrote off to bad debt  expense a total of
$1,293,000  related to this note  bringing the total written off related to this
note since inception to $1,685,000.

      APS Consulting is an environmental  consulting/engineering firm, comprised
of scientists and engineers specializing in remedial investigations, remediation
engineering,  air  quality,  waste  water,  regulatory  compliance,  solid waste
engineering,  litigation support/expert  testimony,  environmental resources and

Mississippi; Mobile, Alabama; and Houston, Texas.

      Because of the wide range of expertise of its consultants,  APS Consulting
serves  clients  in a  broad  base  of  industries,  including:  petrochemicals;
agricultural chemicals; oil exploration,  refining and marketing; gas pipelines;

state and local  government;  and law firms.  Its consultants and engineers have
expertise in  environmental  engineering,  chemical  engineering,  hydrogeology,
computer-aided  drafting and design,  civil  engineering,  geology,  biology and
micro biology.  Revenues from APS Consulting  contributed 4% of Company revenues
in 1999. As revenues and expenses of APS Consulting were not  consolidated  into
the totals of the Company until September,  1999, this percentage  reflects only
four months of revenues from APS Consulting.

REAL ESTATE

      APS  Realty,  Inc.,  ("APS  Realty"),  a  wholly-owned  subsidiary  of the
Company,  owns condominium space in an office project located in Austin,  Texas.
APS  Realty  leases  approximately  58%  of  this  space  to  the  Company,  its
subsidiaries  and affiliate.  The remainder is leased to  unaffiliated  parties.
Revenues from APS Realty  contributed 4%, 4% and 5% of Company revenues in 1999,
1998 and 1997, respectively.

      On January 1, 1998 the Company  invested  approximately  $2,000,000 in the
Convertible  Preferred  Stock of Uncommon  Care,  Inc.  ("Uncommon  Care").  The
Company  also made  available  to Uncommon  Care three lines of credit  totaling
$4,850,000.  The loans are at interest  rates varying from ten percent to twelve
percent,  payable  quarterly  until June 30, 2005, at which time the outstanding
principal and any accrued but unpaid interest are due and payable. Uncommon Care
is a developer  and  operator of  dedicated  Alzheimer's  care  facilities.  The
preferred shares owned by the Company are convertible  into  approximately a 34%
interest in the equity of Uncommon Care.  Two of Uncommon  Care's five directors
are  members of the  Company's  board of  directors.  The  Company  records  its
investment at cost.

      In 1997, the Company formed APS Practice  Management,  Inc., later renamed
Syntera  HealthCare  Corporation  ("Syntera") with an initial  ownership of 85%.
Syntera  specialized in the management of OB/GYN and related medical  practices.
In  a  typical  transaction,  Syntera  acquired  the  non-medical  assets  of  a
physician's  practice  and  signed  a  long-term  management  contract  with the
physician  to  provide  the  majority  of the  non-medical  requirements  of the
practice,  such  as  non-professional   personnel,  office  space,  billing  and
collection,  and other  day-to-day  non-medical  operating  functions.  In turn,
Syntera was paid a variable management fee that rewarded the efficient operation
and the expansion of the practice.  On June 30, 1999 the Company  merged Syntera
with  another  unaffiliated  practice  management  company,  FemPartners,  Inc.,
resulting  in the  Company  owning  approximately  12% of the  total  equity  of
FemPartners, Inc., the surviving company. Prior to June 30, 1999 the Company has
accounted for its ownership in Syntera on the equity  basis.  Beginning  July 1,
1999,  as a result of the merger  with  FemPartners,  Inc.,  the  Company  began
recording its interest on the cost basis.

DISCONTINUED OPERATIONS

      The Company, through its wholly owned subsidiary,  APS Systems, Inc. ("APS
Systems"),  had previously developed software and marketed it to medical clinics
and medical schools.  This business segment became unprofitable in 1996. A joint
venture with a software  developer was formed in 1996 with a plan to develop new
products, but was discontinued in 1997 when it was determined that the high cost
of developing  competitive  products precluded an adequate return on investment.
Subsequently, the Company ceased marketing the software and reduced the scope of
APS Systems'  operations to a level adequate to service existing clients through
the terms of their  contracts.  The Company  reflected  the  expected  financial
impact of discontinuing this segment in the 1997 financial statements.

COMPETITION

      APS  Financial  and  Asset   Management  are  both  engaged  in  a  highly
competitive  business.  Their competitors  include,  with respect to one or more
aspects  of  business,  all of the  member  organizations  of the New York Stock
Exchange and other  registered  securities  exchanges,  all members of the NASD,
registered  investment advisors,  members of the various commodity exchanges and
commercial  banks  and  thrift  institutions.  Many of these  organizations  are
national rather than regional firms and have substantially greater personnel and
financial resources than the Company's. Discount brokerage firms oriented to the
retail market,  including  firms  affiliated  with  commercial  banks and thrift
institutions,   are  devoting   substantial  funds  to  advertising  and  direct
solicitation  of customers in order to increase their share of  commissions  and
other  securities  related income.  In many instances APS Financial is competing
directly  with  such  organizations.  In  addition,  there  is  competition  for
investment funds from the real estate, insurance, banking and thrift industries.

      APIE  competes with  numerous  insurance  companies in Texas and Arkansas,
primarily  Medical  Protective  Insurance  Company,  St.  Paul  Fire and  Marine
Insurance  Company,  State Volunteer Mutual Company,  Frontier  Insurance Group,
Texas Medical  Liability  Trust,  Medical  Interinsurance  Exchange Group of New
Jersey  and PHICO  Insurance.  Many of these  firms have  substantially  greater
resources than APIE. The primary  competitive  factor in selling  insurance is a
combination of price,  terms of the policies  offered,  claims service and other
services, and claims settlement philosophy.

      APS Consulting  operates in the  environmental  services  industry that is
characterized by intense competition. Many companies of all sizes are engaged in
activities  similar to those of the APS Consulting and many of APS  Consulting's
competitors  have  substantially  greater  assets  and  capital  resources.  APS
Consulting  operates primarily in the Southeastern United States,  however,  the
Company has projects  throughout  the United  States.  APS  Consulting  seeks to
distinguish   its   services  by  (i)   providing   timely,   high  quality  and
cost-effective solutions to the various environmental issues facing its clients,
(ii) maintaining  long-term  relationships with its clients, and (iii) utilizing
technology to provide state of the art services in  accordance  with  applicable
regulatory  standards.  There can be no assurance,  however, that APS Consulting
can compete successfully against its competitors,  given the size, resources and
marketing capabilities of many of its competitors.

REGULATION

      APS Financial  and Asset  Management  are subject to extensive  regulation
under both federal and state laws.  The SEC is the federal  agency  charged with
administration  of the federal  securities and investment  advisor laws. Much of
the regulation of broker dealers, however, has been delegated to self-regulatory
organizations, principally the NASD and the national securities exchanges. These
self-regulatory organizations adopt rules (subject to approval by the SEC) which
govern the industry and conduct periodic examinations of member  broker/dealers.
APS  Financial is also subject to  regulation  by state and District of Columbia
securities commissions.

                                        8

<PAGE>

      The regulations to which APS Financial is subject cover all aspects of the
securities  business,  including  sales methods,  trade  practices  among broker
dealers,  uses and  safekeeping  of  customers'  funds and  securities,  capital
structure of  securities  firms,  record  keeping and the conduct of  directors,
officers and employees. Additional legislation,  changes in rules promulgated by
the SEC and by self regulatory  organizations,  or changes in the interpretation
or  enforcement  of existing laws and rules,  may directly  affect the method of
operation  and  profitability  of  APS  Financial.   The  SEC,  self  regulatory
organizations  and  state  securities  commissions  may  conduct  administrative
proceedings  which can result in censure,  fine,  suspension or expulsion of APS
Financial,  its officers or employees.  The principal  purpose of regulation and
discipline of  broker/dealers  is the protection of customers and the securities
markets, rather than protection of creditors and shareholders of broker/dealers.

      APS Financial, as a registered broker dealer and NASD member organization,
is required by federal law to belong to the SIPC. When the SIPC fund falls below
a certain  minimum  amount,  members are required to pay annual  assessments  in
varying  amounts not to exceed .5% of their  adjusted  gross revenues to restore
the  fund.  The last  assessment  of APS  Financial  by the SIPC was in 1995 and
amounted to approximately $7,300. The SIPC fund provides protection for customer
accounts up to $500,000 per  customer,  with a limitation  of $100,000 on claims
for cash balances.

      FMI has received  certificates  of  authority  from the Texas and Arkansas
insurance departments,  licensing it on behalf of the subscribers of APIE. APIE,
as an insurance company,  is subject to regulation by the insurance  departments
of the  States of Texas  and  Arkansas.  These  regulations  strictly  limit all
financial  dealings  of a  reciprocal  insurance  exchange  with  its  officers,
directors,   affiliates  and   subsidiaries,   including  FMI.   Premium  rates,
advertising,  solicitation of insurance,  types of insurance  issued and general
corporate activity are also subject to regulation by various state agencies.

      APS Consulting is subject to extensive laws and regulations promulgated by
the Federal, state and local governments and regulatory authorities dealing with
the discharge of materials  into the  environment  or otherwise  relating to the
protection of the  environment.  The Company believes it is in compliance in all
material respects with all such laws and regulations.

EMPLOYEES

      At  March  1,  2000,  the  Company   employed,   on  a  full  time  basis,
approximately  128  persons,  including  48 by  Insurance  Services,  50 by  APS
Investment  Services,  18 by APS Consulting and 12 directly by the Company.  The
Company  considers  its  employee  relations to be good.  None of the  Company's
employees is  represented  by a labor union and the Company has  experienced  no
work stoppages.

FORWARD-LOOKING STATEMENTS

      The  statements  contained in this Report on Form 10-K that are not purely
historical are  forward-looking  statements within the meaning of Section 27A of
the  Securities  Act of 1933 and Section 21E of the  Securities  Exchange Act of
1934,  including  statements  regarding  the  Company's   expectations,   hopes,
intentions or strategies  regarding the future.  Readers  should not place undue
reliance on forward-looking  statements. All forward-looking statements included
in this document are based on  information  available to the Company on the date
hereof, and the Company assumes no obligation to update any such forward-looking
statements.  It is important to note that the  Company's  actual  results  could
differ materially from those in such forward-looking  statements. In addition to
any risks and uncertainties specifically identified in the text surrounding such
forward-looking  statements,  the reader should consult the Company's reports on
Forms 10-Q and other filings under the Securities Act of 1933 and the Securities
Exchange  Act of 1934,  for factors  that could cause  actual  results to differ
materially from those presented.

      The  forward-looking  statements  included herein are necessarily based on
various  assumptions  and estimates and are inherently  subject to various risks
and  uncertainties,  including risks and uncertainties  relating to the possible
invalidity of the underlying  assumptions and estimates and possible  changes or
developments  in  social,  economic,   business,  industry,  market,  legal  and
regulatory circumstances and conditions and actions taken or omitted to be taken
by  third  parties,  including  customers,   suppliers,  business  partners  and
competitors and  legislative,  judicial and other  governmental  authorities and
officials. Assumptions relating to the foregoing involve judgements with respect
to, among other things,  future economic,  competitive and market conditions and
future business  decisions,  all of which are difficult or impossible to predict
accurately  and many of which are beyond the  control of the  Company.  Any such
assumptions could be inaccurate and,  therefore,  there can be no assurance that
the  forward-looking  statements included in this Report on Form 10-K will prove
to be accurate.

RESULTS OF OPERATIONS

1999 COMPARED TO 1998

      Revenues  from  continuing  operations  increased  17% in 1999 compared to
1998. Net income  decreased 9% and diluted earnings per share increased 45%. The
reasons for these changes are described below.

FINANCIAL SERVICES

      Financial  services  revenues  increased 9% in 1999 compared to 1998.  The
increase  resulted  from  greater  commissions  earned  at  APS  Financial,  the
broker/dealer division of Investment Services, resulting from greater volatility
in world bond markets which caused clients to realign portfolios.  This activity
created more  transactions and thus more  commissions.  Also contributing to the
increase was a greater  emphasis on  internally  generated  market  research and
continued success at recruiting experienced,  proven producers.  Internal market
research  contributes to higher commissions by providing  additional  investment
ideas to be marketed by the brokers to a greater  number of customers.  Finally,
inventory losses, which lower revenues, were greater in 1998 than in 1999.

      Financial  services  expenses  increased 8% in 1999 compared to 1998.  The
large   increase  in   transaction   activity  at  APS  Financial   resulted  in
proportionately  greater sales commission  expense,  support personnel  expense,
transaction charges and financial information services expense.  Greater profits
in 1999 also increased expenses under the incentive compensation plan. Personnel
costs also  increased in 1999  primarily as a result of incurring a full year of
personnel costs at APS Asset Management,  the portfolio  management  division of
Investment  Services.  Only six months of personnel costs were incurred in 1998,
as the subsidiary was formed in June, 1998.

      Results in this  segment  can vary from year to year.  The  broker/dealer,
primarily a provider of fixed income  securities,  is subject to general  market
conditions  as well as  interest  rates and is in an industry  characterized  by
competition  for top  producing  brokers.  In an effort to add to the  segment's
overall  profitability,  and to add  stability  from year to year,  the  Company
entered  the asset  management  business  in 1998.  As a  registered  investment
advisor,  Asset  Management,  seeks to manage the portfolios of institutions and
high net worth  individuals.  Asset Management is in a competitive  business and
was not  profitable in 1999,  incurring a loss of $169,000.  The Company  cannot
predict when or if it will achieve profitability.

                                       14

<PAGE>

INSURANCE SERVICES

      Insurance  Service's  revenues decreased 17% in 1999 compared to 1998. The
primary  reason for the  decrease in 1999 was due to lower profit  sharing.  The
insurance management fee contract between Insurance Services and APIE contains a
provision  to share  in the  profits  of APIE.  Due to an  overall  increase  in
competition in medical  professional  liability  insurance in Texas as well as a
continued   trend  of  rising  claims   against  the  insureds,   profits,   and
consequently, profit sharing, were lower in 1999.

      Insurance  Services'  expenses increased 10% in 1999 compared to 1998. The
increase was  primarily due to higher  commission  rates paid to sales agents as
well as to increased  business received through agents requiring  commissions to
be paid.  Personnel costs also increased in 1999, primarily due to normal annual
merit raises.

     Due to the profit sharing  provision in Insurance Services most significant
contract,  results can vary from year to year.  In the last five years under the
contract, profit sharing has ranged from 7% to 31% of the segment's revenues.

CONSULTING

      The  Company  began  consolidating  the  earnings  of  APS  Consulting  in
September, 1999. No comparison to prior year, therefore, is possible.  Unaudited
pro-forma  financials show that revenues  decreased 28% in 1999 due primarily to
the loss of a major client  resulting from the  uncertainty  that arose with the
breakup of Con-Eco.

      Expenses at Consulting decreased 4% in 1999 primarily as a result of fewer
personnel.  The  uncertainty  that arose with the breakup of Con-Eco caused some
personnel to seek other employment opportunities.

REAL ESTATE

      Revenue  decreased less than 1% compared to 1998. The decrease  reflects a
higher vacancy rate, partially offset by higher lease rates.

     The 4% increase in real estate  expenses  resulted from increased  property
taxes due to higher  real  estate  taxable  values and  increased  fees paid for
building maintenance and improvements.

INVESTMENT AND OTHER

      The  substantial  rise in investment and other income was primarily due to
gains from the exchanges of Prime Medical common stock for the Company's  common
stock. As part of a buy-back  strategy,  the Company exchanged 720,700 shares of
Prime Medical  common stock for 1,441,400  shares of the Company's  common stock
held by two mutual fund companies.  The Company's  common stock was then retired
and gains totaling $1,635,000 were recorded.  In addition,  interest of $349,000
was  earned  from line of credit  loans  granted  by the  Company  to its former
physician practice management affiliate, Syntera and to Uncommon Care.

      General and administrative expenses increased 98% over 1998. The increases
resulted  primarily from  recognizing  $1,293,000 of bad debt expense related to
the write-off of the Con-Eco note  receivable  and from expenses  related to the
merger of Syntera with FemPartners. Partially offsetting these expense increases
was lower legal fees in 1999.  Work  performed  in 1998  related to the Uncommon
Care preferred stock investment increased legal fees in 1998.

INTEREST

      Interest  expense  increased  330% over 1998 as a result of an increase in
notes  payable.  Draws  taken  from the  Company's  line of credit  with Bank of
America to fund the Company's  investments in Syntera and Uncommon Care resulted
in an ending  balance of  $3,275,000  at December  31, 1999  compared to zero at
December 31, 1998.

AFFILIATES

      The Company has one affiliate  accounted  for on the equity  basis,  Prime
Medical,  as of December 31, 1999. Prime Medical's operating income increased in
1999 but the  Company  recognized  a smaller  percentage (18% in 1998 vs. 14% in
1999) as a result of its exchange of Prime Medical  shares to acquire  shares of
the Company's common stock. Even with this drop in ownership percentage,  equity
earnings from Prime  Medical  increased  23% in 1999.  The Company,  through its
status as Prime Medical's largest  shareholder and through its representation on
PrimeMedical's  board,  continues to have significant influence at Prime Medical
and continues to account for its investment using the equity method.

      Also  included  in equity in  earnings of  unconsolidated  affiliates  are
losses  totaling  $119,000 which  represents the Company's  portion of losses of
Syntera.  from  January  1 to June  30,  1999.  Subsequent  to the  merger  with
FemPartner's,  the Company began  accounting  for it's resulting 12% interest in
FemPartners on the cost basis.

1998 COMPARED TO 1997

      Revenues  from  continuing  operations  increased  26% in 1998 compared to
1997. Net income decreased 39% and diluted earnings per share decreased 48%. The
reasons for these changes are described below.

                                       16

INVESTMENT SERVICES

      Investment  services' revenues increased 73% in 1998 compared to 1997. The
increase  resulted from volatility in world bond markets which caused clients to
realign  portfolios.  This  activity  created  more  transactions  and thus more
commissions.  Also  contributing  to the increase was the full  development of a
second office,  which opened in 1997.  Revenues at this office in 1998 increased
approximately 90% over 1997.

      Investment services' expenses increased 71% from 1997. 94% of the increase
was at APS Financial and was transaction  volume-related.  The large increase in
revenues resulted in proportionately  greater sales commission expense,  support
personnel  expense,  transaction  charges  and  financial  information  services
expense.  Lower legal fees partially offset these increases.  Greater profits in
1998  also  increased  expenses  under  the  incentive  compensation  plan.  The
remainder  of the  increase  in  expenses  was  the  result  of  starting  Asset
Management in 1998.

INSURANCE SERVICES

      Insurance  Services'  revenues decreased 10% in 1998 compared to 1997. The
loss of one significant  client by APIE caused most of the variance.  The client
purchased extended reporting period or "tail" coverage, which increased premiums
in 1997.  1998  revenues  were lower by both the standard  premium and the extra
tail premiums lost in 1997. The Company's premium-based  management fee was also
proportionately  lower.  The  remainder  of the  decrease  was related to profit
sharing.  The insurance management fee contract contains a provision to share in
the profits of the  managed  insurance  exchange.  Due to the loss of the client
mentioned above and an overall  increase in competition in medical  professional
liability insurance in Texas,  profits, and consequently,  profit sharing,  were
lower in 1998.

      Insurance  Services' expenses increased 8% over 1997. The increase was the
result of increased commission expense and was due to the greater utilization of
commissioned  outside sales agents,  compared to salaried internal  personnel in
prior years.  Lower salary expense,  primarily due to lower incentive  payments,
partially offset the increased commissions.

      Due to the profit  sharing  provision in this  segment's  major  contract,
results can vary from year to year.  In the last five years under the  contract,
profit sharing has ranged from 12% to 31% of the segment's revenues.

REAL ESTATE

      Revenue  increased 1% compared to 1997. The increase reflects higher lease
rates, partially offset by a higher vacancy rate.

      The 5% increase in real estate expenses  resulted from increased  property
taxes due to higher real estate values.

                                       17

INVESTMENT AND OTHER

      The decline in  investment  and other  income was  primarily  due to lower
interest income, a result of available cash being fully invested in new start-up
companies, which yielded no current return.

GENERAL AND ADMINISTRATIVE EXPENSES

      General and administrative expenses increased 37% over 1997. The increases
resulted  from  recognizing  bad debt expense  related to the  impairment of the
Con-Eco note receivable and from expenses  related to guaranteeing an individual
investor's investment return. The Company had agreed to the guaranteed return to
settle  a  dispute   on  the   customer's   account  in  1995.   The   portfolio
under-performed  in 1998 and additional  funds were  contributed by the Company.
Lower management incentive expenses partially offset these increases in 1998.

      Interest  expense  increased  from $21,000 in 1997 to $59,000 in 1998. The
increase  reflects funds borrowed under the line of credit to fund the Company's
investments Syntera and Uncommon Care.

AFFILIATES

      The Company had two  affiliates  accounted for on the equity basis,  Prime
Medical and Syntera.  Prime Medical's operating income increased in 1998 but net
earnings were reduced by  non-recurring  financing and development  costs.  This
resulted in a 23% decrease in equity earnings compared to 1997.  Syntera,  which
was started in 1997,  continued in the development  phase and reported a loss in
1998. The Company's share of Syntera's loss increased approximately 5% in 1998.

      Prime  had  issued  additional  shares  in  1996  reducing  the  Company's
ownership from 21% to 16%. In 1998 Prime established a stock repurchase plan and
reduced its shares outstanding, increasing the Company's ownership percentage to
approximately 18%.

LIQUIDITY AND CAPITAL RESOURCES

      Net working capital was $1,582,000 and $1,782,000 at December 31, 1999 and
1998,  respectively.  The  decrease  in the  current  year is due  primarily  to
payments for purchases of property and equipment.  Historically, the Company has
maintained a strong working capital position and, using that base, has been able
to satisfy  its  operational  and  capital  expenditure  requirements  with cash
generated  from its operating and  investing  activities.  These same sources of
funds  have  also  allowed  the  Company  to  pursue  investment  and  expansion
opportunities   consistent   with  its  growth  plans.   In  1999,  the  Company
supplemented these traditional sources of funds with short-term bank borrowings.
Although it is uncertain that operating  activities  will provide  positive cash
flow in the year 2000, the Company has sufficient  borrowing capacity as well as
ample  liquidity  in its  holdings of Prime  Medical  shares to meet its working
capital requirements for the foreseeable future.

                                       18

<PAGE>

      In 1998,  the  Company  entered  into a three year  $10,000,000  revolving
credit agreement with NationsBank of Texas, N.A.  (subsequently acquired by Bank
of America, N.A.). Funds advanced under the agreement bear interest at the prime
rate less 1/4 %, such interest to be payable quarterly.  The Company will pledge
shares of Prime Medical to the bank as funds are advanced under the line. In May
1999,  as a result of the exchange of Prime  Medical  shares for common stock of
the Company, the revolving credit agreement was amended to lower the total funds
available  to  the  Company  from  $10,000,000  to  $7,500,000.  Funds  totaling
$3,275,000  and  $2,625,000  had been advanced as of December 31, 1999 and March
15, 2000, respectively.

      Capital expenditures for equipment were $413,000,  $206,000, and $312,000,
in 1999, 1998, and 1997, respectively.  Capital expenditures were higher in 1999
due to purchases necessary to reach compliance with Year 2000 computer issues as
well as to higher  expenditures  for improved office space and leasing fees. The
Company expects capital expenditures in 2000 to be significantly less than 1999.

      The Company's  ability to make  scheduled  payments of principal of, or to
pay the  interest  on, or to  refinance,  its  indebtedness,  or to fund planned
capital expenditures will depend on its future performance,  which, to a certain
extent, is subject to general  economic,  financial,  competitive,  legislative,
regulatory and other factors that are beyond its control. Based upon the current
level of operations and  anticipated  revenue growth,  management  believes that
cash flow from operations and available cash, together with available borrowings
under its bank line of credit,  will be  adequate to meet the  Company's  future
liquidity  needs for at least the next several years.  However,  there can be no
assurance that the Company's  business will generate  sufficient  cash flow from
operations,  that anticipated revenue growth and operating  improvements will be
realized or that future borrowings will be available under the line of credit in
an amount  sufficient  to enable the Company to service its  indebtedness  or to
fund its other liquidity needs.

INFLATION

      The operations of the Company are not significantly  affected by inflation
because, having no manufacturing operations, the Company is not required to make
large  investments in fixed assets.  However,  the rate of inflation will affect
certain of the Company's expenses, such as employee compensation and benefits.

NEW ACCOUNTING PRONOUNCEMENTS

      In April  1998,  the  AICPA  issued  Statement  of  Position  (SOP)  98-5,
Reporting on the Costs of Start-Up Activities,  which is effective for financial
statements for fiscal years  beginning after December 15, 1998. The SOP requires
costs of start-up  activities and organization costs to be expensed as incurred.
No start-up costs were incurred by the Company or its affiliate during 1999. The
Company does not have any significant  capitalized  start-up costs that would be
required to be expensed in 2000.

ITEM 7 (a)    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

      The  Company  has some  exposure  to cash  flow and fair  value  risk from
changes in interest rates, which may affect its financial  position,  results of
operation  and cash flows.  The Company does not use financial  instruments  for
speculative  purposes,   but  does  maintain  a  trading  account  inventory  to
facilitate the business of its broker/dealer  subsidiary. At the end of 1999 the
inventory  balance  was  $635,000.  Historically,  the  Company  has turned this
inventory rapidly and has neither significant realized gains nor losses.

      The  Company  has  notes  receivable,  in the form of lines of  credit  to
related  companies,  which are at fixed rates ranging from 8% to 12%. Their fair
value will increase and decrease inversely with interest rates.

      The Company  has debt  totaling  $3,310,000,  most of which was drawn on a
$7,500,000  revolving line of credit with a floating  interest rate. For each $1
million that the Company  should  borrow in 2000, a 1% increase in interest rate
would result in a $10,000 annual increase in interest expense.

         The Board of Directors and Shareholders
         American Physicians Service Group, Inc.:


         We have audited the accompanying  consolidated  financial statements of
         American Physicians Service Group, Inc. and subsidiaries ("Company") as
         listed  in  the  accompanying   index.  These  consolidated   financial
         statements  are the  responsibility  of the Company's  management.  Our
         responsibility is to express an opinion on these consolidated financial
         statements based on our audits.

         We conducted our audits in accordance with generally  accepted auditing
         standards.  Those standards  require that we plan and perform the audit
         to obtain reasonable  assurance about whether the financial  statements
         are free of material  misstatement.  An audit includes examining,  on a
         test basis,  evidence  supporting  the amounts and  disclosures  in the
         financial  statements.  An audit also includes assessing the accounting
         principles used and significant  estimates made by management,  as well
         as evaluating the overall financial statement presentation.  We believe
         that our audits provide a reasonable basis for our opinion.

         American  Physicians  Service Group,  Inc. and subsidiaries at December
         31, 1999 and 1998,  and the results of their  operations and their cash
         flows for each of the years in the three-year period ended December 31,
         1999, in conformity with generally accepted accounting principles.

            AMERICAN PHYSICIANS SERVICE GROUP, INC., AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                        December 31, 1999, 1998 and 1997


(1)      Summary of Significant Accounting Policies

(a)      General

         American  Physicians  Service  Group,  Inc.  through its  subsidiaries,
         provides financial services that include brokerage and asset management
         services to individuals and institutions,  and insurance  services that
         consist of management services for malpractice insurance companies. The
         financial   services   business  has  clients   nationally.   Insurance
         management is a service  provided  primarily in Texas, but is available
         to clients  nationally.  American  Physicians  Service Group, Inc. also
         owns space in the office  building  which  serves as its  headquarters.
         Through its real estate  subsidiary  it leases space that is surplus to
         its  needs.   During  the  three  years   presented  in  the  financial
         statements,  financial  services  generated  57% of total  revenues and
         insurance services generated 24%.

         American Physicians Services Group, Inc. has one affiliate; Prime
         Medical  Services,  Inc., of which it owns  approximately  14%. Prime
         Medical is the country's largest provider of  lithotripsy (non-invasive
         kidney stone  fracturing)  services.  The Company also has a preferred
         stock investment in a company which develops and operates Alzheimer's
         care facilities.

(b)      Estimates

         The  preparation of financial  statements in conformity  with generally
         accepted  accounting  principles  requires management to make estimates
         and  assumptions  that  affect  the  reported  amounts  of  assets  and
         liabilities and disclosure of contingent  assets and liabilities at the
         date of the financial  statements and the reported  amounts of revenues
         and expenses during the reporting  period.  Actual results could differ
         from those estimates.

(c)      Principles of Consolidation

         The consolidated  financial statements include the accounts of American
         Physicians  Service Group,  Inc. and of subsidiary  companies more than
         50% owned  ("Company").  Investments in affiliated  companies and other
         entities  in which  the  Company's  investment  is less than 50% of the
         common  shares  outstanding  and where the Company  exerts  significant
         influence are accounted for by the equity method.  Investments in other
         entities  in  which  the  Company's  investment  is  less  than  20% is
         accounted for by the cost method.

         All  significant  intercompany  transactions  and  balances  have  been
         eliminated from the accompanying consolidated financial statements.

         Summary of Significant Accounting Policies, continued

         (d)      Revenue Recognition

         Investment  services  revenues  related to securities  transactions are
         recognized on a trade date basis.

         Insurance  services  revenues related to management fees are recognized
         monthly as a percentage of the earned premiums of the managed  company.
         The profit  sharing  component of these fees is  recognized  when it is
         reasonably certain that the managed company will have an annual profit,
         generally in the fourth quarter of each year.

         Consulting revenues related to environmental  engineering/consulting is
         recognized monthly based upon billable hours.

         Real estate rental  income is  recognized  monthly over the term of the
         lease.  Costs of leasehold  improvements  are capitalized and amortized
         monthly over the term of the lease.

         Investment   revenues  are   recognized  as  accrued  on  highly  rated
         investments and as received on lesser grades.

         (e)      Marketable Securities

         The Company's  investments in debt and equity securities are classified
         in three categories and accounted for as follows:

                  Classification                       Accounting

                  Held to maturity                     Amortized cost

                                                       gains and losses included
                                                       in earnings

                  Available                            for  sale   Fair   value,
                                                       unrealized    gains   and
                                                       losses    excluded   from
                                                       earnings  and reported as
                                                       a separate  component  of
                                                       stockholders' equity, net

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                        December 31, 1999, 1998 and 1997

(1)      Summary of Significant Accounting Policies, continued

         The Company has included its marketable  securities,  held as inventory
         at its broker/dealer, in the trading securities category.

         (f)      Property and Equipment

         Property and equipment  are stated at cost.  Property and equipment and
         rental property are depreciated using the straight-line method over the
         estimated useful lives of the respective assets (3 to 40 years).

         (g)      Long-Lived Assets

         Long-lived  assets  are  reviewed  for  impairment  whenever  events or
         changes in  circumstances  indicate that the carrying amount may not be
         recoverable.  If the sum of the expected future undiscounted cash flows
         is less than the carrying  amount of the asset, a loss is recognized if
         there is a difference  between the fair value and carrying value of the
         asset.

         (h)      Goodwill

         Goodwill  represents  the  excess  of  consideration  paid over the net
         assets  acquired in purchase  business  combinations.  It is  amortized
         using the straight-line method over a period of ten years.

         (i)      Income Taxes

         Deferred tax assets and  liabilities  are recognized for the future tax
         consequences   attributable   to  differences   between  the  financial
         statement carrying amounts of existing assets and liabilities and their
         respective tax bases and operating  loss and tax credit  carryforwards.
         Deferred  tax assets and  liabilities  are measured  using  enacted tax
         rates  expected to apply to taxable  income in the years in which those
         temporary  differences  are expected to be  recovered  or settled.  The
         effect on deferred tax assets and  liabilities of a change in tax rates
         is recognized in income in the period that includes the enactment date.

         (j)      Earnings Per Share

         Basic  earnings  per  share  is based on the  weighted  average  shares
         outstanding  without any diluted effects  considered.  Diluted earnings
         per share  reflect  dilution  from all  contingently  issuable  shares,
         including options.

(1)      Summary of Significant Accounting Policies, continued

         (k)      Cash and Cash Equivalents

         Cash and cash  equivalents  include cash and highly liquid  investments
         with an original maturity of 90 days or less.

         (l)      Notes Receivable

         Notes  receivable  are recorded at cost,  less  allowances for doubtful
         accounts  when  deemed  necessary.   Management,   considering  current
         information and events  regarding the borrowers  ability to repay their
         obligations,  considers a note to be impaired  when it is probable that
         the Company will be unable to collect all amounts due  according to the
         contractual  terms of the note agreement.  When a loan is considered to
         be  impaired,  the amount of the  impairment  is measured  based on the
         present  value of expected  future cash flows  discounted at the note's
         effective  interest  rate.   Impairment  losses  are  included  in  the
         allowance for doubtful  accounts  through a charge to bad debt expense.
         The present  value of the impaired loan will change with the passage of
         time and may  change  because  of  revised  estimates  of cash flows or
         timing of cash flows.  Such value changes shall be reported as bad debt
         expense in the same manner in which impairment initially was recognized
         or as a  reduction  in the  amount of bad debt  expense  that  would be
         reported.

         (m)      Stock-Based Compensation

         The Company has adopted the disclosure-only  provisions of Statement of
         Financial  Accounting  Standards No. 123,  Accounting  for  Stock-Based
         Compensation ("Statement 123"), but applies Accounting Principles Board
         Opinion No. 25, Accounting for Stock Issued to Employees, in accounting
         for its stock option plans.

         (n)      Reclassification

         Certain  reclassifications  have  been  made to  amounts  presented  in
         previous years to be consistent with the 1999 presentation.

         (o)      Other Comprehensive Income

         For the three years ended  December 31, 1999,  the Company did not have
         any significant other comprehensive income.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                        December 31, 1999, 1998 and 1997

(3)      Notes Receivable, continued

         Various  officers  and  directors  of the Company  participated  in the
         $2,400,000 line of credit to Uncommon Care. For financial purposes this
         participation has been treated as the sale of a financial asset. In the
         aggregate  these  officers  and  directors  contributed   approximately
         $259,000 to fund a 10.8% interest in the loan. They participated in the
         earnings from the loan on a pro-rata basis.

         On October 31, 1996, the Company invested $3,300,000 in common stock of
         Exsorbet Industries, Inc. ("Exsorbet") (NASDAQ:EXSO) with a put option.
         Exsorbet  was  a  diversified   environmental  and  technical  services
         company.  On  November  26,  1996,  the  Company  exercised  its put in
         exchange for a note receivable  from Exsorbet.  The note was secured by
         the shares  that were  subject to the put option plus all the stock and
         substantially  all  of the  assets  of a  wholly  owned  subsidiary  of
         Exsorbet.   Subsequently,   Exsorbet   became  known  as   Consolidated
         Eco-Systems, Inc. ("Con-Eco").

         On June 17,  1998 the  Company  filed  suit  against  Con-Eco,  and its
         directors  and  officers   alleging   breach  of  contract,   negligent
         misrepresentation and conspiracy. In February, 1999 the Company settled
         this litigation with the directors and officers of Con-Eco. The Company
         recovered  $950,000  for the full  release  of all claims  against  the
         directors of Con-Eco.

         In April,  1999, the Company's wholly owned subsidiary,  APS Consulting
         ("APS  Consulting"),   acquired  the  business  of  Eco-Systems,   Inc.
         ("Eco-Systems"),  a subsidiary of Con-Eco,  in  connection  with a debt
         restructuring   agreement   with  Con-Eco.   Under  the  terms  of  the
         restructuring  agreement,  Con-Eco had the right to  purchase  back the
         business of  Eco-Systems  for a nominal  amount upon the  occurrence of
         certain  conditions.   Accordingly,   the  Company  did  not  initially
         consolidate the operations of APS Consulting.  In addition, the Company
         dismissed  its  lawsuit  against  Con-Eco,  but  retained  the right to
         reinstitute the litigation at a later date.

         Subsequently,  the  Company  concluded  that it was not  probable  that
         Con-Eco would exercise its option to reacquire the stock and, effective
         September 1, 1999, the Company began consolidating APS Consulting.  The
         acquisition  was recorded using the purchase  method of accounting.  In
         addition,  the Company wrote off the remaining  balance of the note due
         from  Con-Eco.  During the year  ended  December 31, 1999 the Company
         wrote off to bad debt expense a total of $1,293,000 bringing the total
         written off since inception to $1,685,000.

(3)      Notes Receivable, continued

         At December 31, 1998, the Company's note receivable  from  Consolidated
         Eco-Systems,  Inc.  was in excess of 10% of  stockholder's  equity  and
         represented a concentration of credit risk. No interest income had been
         recognized by the Company as of December 31, 1998.

         Following  a  renegotiation  of the  debt  in  November  1997,  Con-Eco
         defaulted on the note.  Con-Eco's stock was delisted during 1998 as the
         Company  considered  the loan to be impaired. A portion of the note
         receivable was written off in 1999 prior to the acquisition of
         Eco-Systems (See Note 18) and has been recorded as follows:

                                                              December 31,

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                        December 31, 1999, 1998 and 1997

(4)      FAIR VALUE OF FINANCIAL INSTRUMENTS

         Statements  of Financial  Accounting  Standards  No. 107,  "Disclosures
         About Fair Value of Financial  Instruments"  (Statement 107),  requires
         that the  Company  disclose  estimated  fair  values for its  financial
         instruments as of December 31, 1999 and 1998.

         For financial  instruments  the fair value equals the carrying value as
         presented in the  consolidated  balance sheets.  Fair value  estimates,
         methods,  and  assumptions  are  set  forth  below  for  the  Company's
         financial instruments.

         CASH AND CASH EQUIVALENTS

         The carrying  amounts for cash and cash  equivalents  approximate  fair
         value  because  they  mature  in less  than 90 days and do not  present
         unanticipated credit concerns.

         TRADING ACCOUNT SECURITIES

         The fair value of  securities  owned is  estimated  based on bid prices
         published in  financial  newspapers  or bid  quotations  received  from
         securities  dealers.  Trading account  securities are carried at market
         value.

         MANAGEMENT FEES AND OTHER RECEIVABLES

         The fair value of these receivables approximates the carrying value due
         to their short-term nature and historical collectibility.

         NOTES RECEIVABLE

         The fair value of notes has been determined using discounted cash flows
         based on management's  estimate of current  interest rates for notes of
         similar credit quality.  On notes determined to be impaired,  the notes
         have been discounted based on the original interest rate of the note.

         RECEIVABLE FROM CLEARING BROKER

         The carrying  amounts  approximate  fair value because the funds can be
         withdrawn on demand and there is no unanticipated credit concern.

(4)      Fair Value of Financial Instruments, continued

         OTHER INVESTMENTS

         The fair value has been determined using discounted cash flows based on
         estimates of future earnings.

         Accounts Payable

         The fair value of the payable  approximates  carrying  value due to the
         short-term nature of the obligation.

         LIMITATIONS

         Fair value  estimates  are made at a specific  point in time,  based on
         relevant  market   information  and  information  about  the  financial
         instrument.  Fair  value  estimates  are based on  existing  on-and-off
         balance sheet financial  instruments without attempting to estimate the
         value of  anticipated  future  business  and the  value of  assets  and
         liabilities  that  are  not  considered  financial  instruments.  Other
         significant  assets and liabilities  that are not considered  financial
         assets or  liabilities  include the deferred  tax assets,  property and

         income tax payable. In addition,  the tax ramifications  related to the
         realization of the  unrealized  gains and losses can have a significant

(7)      Notes Payable

         The Company has a $7,500,000 line of credit with Bank of America, N. A.
         The Company has pledged  shares of Prime Medical to the bank as funds
         are advanced  under the line.  Funds  advanced  under the agreement
         were  $3,275,000 at December 31, 1999.  Funds advanced under
         the  agreement  will bear  interest  at the prime  rate less 1/4 %. The
         unused portion of the line carries a 1/4 % commitment fee. All interest
         is to be paid  quarterly.  Any  outstanding  principal is to be paid at
         maturity in February 2001.

         In order to receive  advances under the line, the Company must maintain
         certain  levels of liquidity  and net worth.  In  addition,  the market
         value of the  collateral  must  exceed a certain  multiple of the funds
         advanced  under the line and there must be no  occurrence  which  would
         have a material  adverse  effect on the  Company's  ability to meet its
         obligations to the bank. As of December 31, 1999, the Company is in
         Compliance with all covenants of its loan agreements.

                        December 31, 1999, 1998 and 1997

(8)      Commitments and Contingencies

         In connection with the development of Syntera  HealthCare  Corporation,
         the Company entered into Share Exchange Agreements  ("Agreements") with
         the physician  shareholders of Syntera. The Agreements provide that the
         Syntera shareholders  may, at their option,  exchange  their shares for
         a fixed dollar amount of the Company's common stock in the event that
         the Syntera shares are not publicly traded by certain dates.The Company
         has the option of  purchasing  any or all of the shares at the weighted
         average dollar amount of $5.26 per share rather than exchanging for its
         common stock. As a result of Syntera's merger with FemPartners, Inc. in
         1999, the Syntera shares were  converted to  FemPartners  shares,  with
         such shares  retaining  all of the  conversion  features.  These shares
         begin to become  eligible to exchange in the first  quarter of 2000 and
         continue to become eligible into the first quarter of 2002.  Should all
         eligible FemPartners shares (248,000) be presented for exchange and the
         Company  elected to purchase  the shares for cash,  the amount would be
         approximately  $3,900,000.  If the Company  elected to issue its common
         shares,  the quantity  would be  determined  by the market price of its
         shares at the time of the exchange.  For example,  at the closing price
         at December 31, 1999 ($3.688)  approximately  1,100,000 shares would be
         issued in the  exchange.  Since it is unknown how many,  if any, of the
         shares  will  be   presented   for   exchange  or  what  the  value  of
         privately-held  FemPartners  shares will be in the future,  the Company
         has made no provision  related to potential  exchanges in its financial
         statements.  The  Company  will  record the  effect,  if any,  of share
         exchanges  in the  quarter  in  which  it is  notified  by  FemPartners
         shareholders of their intent to exchange.

         The Company has extended three lines of credit to Uncommon  Care,  Inc.
         The first is to a maximum  amount of  $2,400,000.  The note is interest
         only at 10%,  payable  quarterly.  The note matures  June 30, 2005,  at
         which time all principal  and accrued but unpaid  interest are due. The
         second is to a maximum of  $1,250,000  with  interest  at 12%,  payable
         semi-annually.  The note matures  April 30,  2000,  but may be extended
         until  November 30, 2001.  The maturity may be  accelerated by Uncommon
         Care  securing  certain  equity  capital.  The third is to a maximum of
         $1,200,000  with  interest  at 10%,  payable  semi-annually.  The  note
         matures  the earlier of  September  30,  2001,  or upon  Uncommon  Care
         securing  certain equity capital.  Advances under the lines are subject
         to Uncommon  Care meeting  certain  qualifications  at the date of each
         advance request.

(8)      Commitments and Contingencies, continued

         The Company has guaranteed the future yield of a customer's  investment
         portfolio  beginning in January 1995 for up to a five and one-half year
         period.  Management  believes that the Company's  financial  statements
         adequately  provide for any loss that might occur under this agreement;
         however,  as  defined  in  AICPA  Statement  of  Position  94-6,  it is
         reasonably  possible that the  Company's  estimate of loss could change
         over the  remaining  term of the  agreement.  Management  is  unable to
         determine  the  range  of  potential  adjustment  since  it is based on
         securities markets, which are beyond its ability to control.

         The Company had  guaranteed  a loan in the amount of $85,000 for one of
         its directors at December 31, 1999. The guarantee was collateralized by
         securities  the  Company  believed  sufficient  to cover its  potential
         liability.  The loan was paid in full and the Company was released from
         its guarantee on March 5, 2000.

         Rent expense  under all operating  leases for the years ended  December
         31, 1999, 1998 and 1997 was $84,000,  $44,000 and $89,000 respectively.
         Future minimum  payments for leases which extend for more than one year
         were $334,000 at December 31, 1999.

         The Company is involved in various  claims and legal  actions that have
         arisen in the ordinary course of business. Management believes that any
         liabilities  arising  from these  actions  will not have a  significant
         adverse effect on the financial condition of the Company.

         Income tax expense (benefit) consists of the following:

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                        December 31, 1999, 1998 and 1997

(9)      Income Taxes, continued

         The net change in the total  valuation  allowance  for the years  ended
         December  31,  1999 and 1998 was a  decrease  of  $14,000  and  $2,000,
         respectively.  The Company  believes  that the  valuation  allowance at
         December 31, 1999 is necessary due to  uncertainties  regarding the use
         of the net operating loss carryforwards from separate return years of a
         subsidiary acquired in 1997.

         At December 31, 1999,  net operating  loss  carryforwards  available to
         reduce future taxable  income  amounted to  approximately  $505,000 and
         expire in 2011 and 2012.

         In assessing the realizability of deferred tax assets, management
         considers whether it is more likely than not that some portion or all
         of the deferred tax assets will not be realized. The ultimate realiza-
         tion of deferred tax assets is dependent upon the generation of future
         taxable income during the periods in which those temporary defferences
         become deductible. Management considers the scheduled reversal of
         deferred tax liabilities, projected future taxable income, and tax
         planning strategies in making this assessment. Based upin the level of
         historical taxable income and projections for future taxable income
         over the periods which the deferred tax assets are deductible, manage-
         ment believes it is more likely than not that the Company will realize
         the benefits of these deductible differences net of existing valuation
         allowances at December 31, 1999 and 1998.

(10)     Employee Benefit Plans

         The Company has an  employee  benefit  plan  qualifying  under  Section
         401(k)  of the  Internal  Revenue  Code  for  all  eligible  employees.
         Employees   become  eligible  upon  meeting  certain  service  and  age
         requirements.  Employees may defer up to 15% (not to exceed  $10,000 in
         1999) of their annual  compensation under the plan. The Company, at its
         discretion,  may  contribute  up to  200%  of the  employees'  deferred
         amount.  For  the  years  ended  December  31,  1999,  1998  and  1997,
         contributions  by  the  Company  aggregated,   $121,000,  $126,000  and
         $92,000, respectively.

(11)     Stock Options

         The  Company  has  adopted,  with  shareholder   approval,   the  "1995
         Non-Employee  Directors Stock Option Plan"  ("Directors  Plan") and the
         "1995  Incentive  and  Non-Qualified  Stock  Option  Plan"  ("Incentive
         Plan").  The Directors  Plan provides for the issuance of up to 200,000
         shares  of  common  stock to  non-employee  directors  who serve on the
         Compensation  Committee.  The  Directors  Plan  is  inactive  and it is
         assumed the remaining 50,000 shares will not be granted.  The Incentive
         Plan, as amended with  shareholder  approval in 1998,  provides for the
         issuance of up to 1,200,000  share of common stock to directors and key
         employees.

(11)     Stock Options, continued

         The exercise price for each non-qualified option share is determined by
         the Compensation Committee of the Board of Directors ("the Committee").
         The exercise price of a qualified  incentive  stock option has to be at
         least 100% of the fair market value of such shares on the date of grant
         of the option.  Under the Plans, option grants are limited to a maximum
         of ten-year  terms;  however,  the  Committee  has issued all currently
         outstanding  grants with five-year terms. The Committee also determines
         vesting for each option grant and all outstanding options vest in three
         approximately  equal annual  installments  beginning  one year from the
         date of grant.

         The Company has adopted the disclosure-only  provisions of Statement of
         Financial  Accounting  Standards No. 123,  Accounting  for  Stock-Based
         Compensation ("Statement 123"), but applies Accounting Principles Board
         Opinion No. 25, Accounting for Stock Issued to Employees, in accounting
         for its  stock  option  plans.  No cost from  stock-based  compensation
         awards was recognized in 1999, 1998 or 1997. If the Company had elected
         to recognize  compensation  cost of options  granted  based on the fair
         value at the grant dates, consistent with Statement 123, net income and
         earnings  per  share  would  have  changed  to the  pro  forma  amounts

         The Company,  through its wholly owned  subsidiary,  APS Systems,  Inc.
         ("APS Systems"),  had previously  developed software and marketed it to
         medical  clinics and medical  schools.  This  business  segment  became
         unprofitable  in 1996. A joint  venture with a software  developer  was
         formed  in  1996  with  a  plan  to  develop  new  products,   but  was
         discontinued  in 1997  when it was  determined  that the  high  cost of
         developing   competitive  products  precluded  an  adequate  return  on
         investment. Subsequently, the Company ceased marketing the software and
         reduced the scope of APS  Systems'  operations  to a level  adequate to
         service

         originally  assumed  that all  clients  would  have  migrated  to other
         software  products  by the  end of  1999  and  reflected  the  expected

         losses from the disposal was May 15, 1997.  Support for all clients was
         terminated as of December 31, 1999 including two clients whose original
         support contracts extended beyond 1999. These clients have successfully
         migrated  to  other  software   platforms  and  have  signed  documents

         At December 31, 1999 the Company had long-term contracts with company A
         and was  therefore  not  vulnerable  to the risk of a near-term  severe
         impact from a reasonably possible loss of the revenue.

         Operating profit is operating revenues less related expenses and is all
         derived from domestic operations.  Identifiable assets are those assets
         that  are  used in the  operations  of  each  business  segment  (after
         elimination of investments in other segments). Corporate assets consist
         primarily  of  cash  and  cash   investments,   notes   receivable  and
         investments in affiliates and preferred stock.

(15)     Earnings Per Share

         Basic  earnings  per  share are based on the  weighted  average  shares
         outstanding without any dilutive effects  considered.  Diluted earnings
         per share  reflects  dilution from all  contingently  issuable  shares,
         including  options and convertible debt. A reconciliation of income and
         average shares outstanding used in the calculation of basic and diluted
         earnings per share from continuing operations follows:

         APS Financial  acted as the placement  agent for a private  offering of
         500,000 shares of preferred stock for one of its customers during 1999.
         The customer acted as its own underwriter and APS Financial  placed the
         securities on a best effort basis. The private offering closed December
         15, 1999. In association with this transaction,  APS Financial acted in
         a trustee  capacity  and  established  an escrow  fund that was used to
         account for funds received from  participating  investors.  These funds
         were  subsequently  disbursed to the customer based on the satisfaction
         of  certain  criteria.  As of  December  31,  1999,  there  was  $3,494
         maintained  in the escrow fund  related to interest  earnings on escrow
         fund  balances  that  are  payable  to the  customer.  In  addition  to
         establishing  the escrow  fund,  the customer was required to deposit a
         specified  amount with APS  Financial  as part of the private  offering
         agreement.  As of December 31, 1999, APS Financial was holding $372,922
         as a deposit for the customer.

         On January 1, 1998 the Company invested approximately $2,078,000 in the
         Convertible  Preferred Stock of Uncommon Care, Inc.  ("Uncommon Care").
         Uncommon Care is a developer and operator of dedicated Alzheimer's care
         facilities.  The preferred  shares owned by the Company are convertible
         into approximately a 34% interest in the equity of Uncommon Care.

         On June 30, 1999 the Company merged  Syntera with another  unaffiliated
         practice  management  company,  FemPartners,  Inc.,  resulting  in  the
         Company owning  approximately  12% of the total equity of  FemPartners,
         Inc. Prior to June 30, 1999 the Company has accounted for its ownership
         in Syntera on the equity basis.  Beginning July 1, 1999, as a result of
         the merger with  FemPartners,  Inc.,  the Company  began  recording its
         interest on the cost basis.

         In addition to acting as the placing agent for the private  offering as
         described in Note 16, APS Financial  purchased  10,000 shares which has
         been  recorded as a  preferred  stock  investment  with a cost basis of
         $100,000 at December 31, 1999.

         In addition to receiving commission revenue for acting as the placement
         agent for the private  offering,  APS  Financial  received  warrants to
         purchase 251,325 shares of restricted  common capital stock exercisable
         at a price of $1.875 per share of common stock.  The warrants expire on
         December 15, 2004 and have been  recorded at a fair value of $45,000 at
         December  31,  1999.  None of the  warrants  have been  exercised as of
         December 31, 1999.

<PAGE>

                  (a)  Conversion of  Securities.  All of the  Company's  common
stock,  $0.001  par  value  per  share  ("Company  Common  Stock"),  issued  and
outstanding immediately prior to the Effective Time (excluding any shares of the
Company  Common  Stock to be  canceled  pursuant  to  Section  3.1(b))  shall be
converted into the right to receive at Closing, in the aggregate, 885,714 shares
(as such  number  may be  adjusted  pursuant  to  Section  3.2 and as  otherwise
provided  in  this  Agreement,   the  "Merger   Consideration")  of  issued  and
outstanding  common stock,  par value $.01 per share,  of Parent ("Parent Common
Stock").  The aggregate  consideration  payable to each Shareholder is set forth
opposite  each  Shareholder's  name on  Schedule  3.1(a),  and,  subject  to the
provisions  of the  Agreement,  shall  be paid in  full  at  Closing;  provided,
however,  that until  satisfaction  of the  obligations of the Company,  if any,
under  Sections  3.2 and 10.1  hereof,  the  Parent  shall  retain  in escrow an
aggregate of thirty percent (30%) of the Share Equivalent  Transaction Value (as
defined in Section 3.2) in shares of Parent  Common Stock (as such number may be
adjusted pursuant to Section 3.3 and as may be subject to forfeiture pursuant to
Article X, the  "Retained  Shares").  A number of the  Retained  Shares equal to
fifteen percent (15%) of the Share Equivalent Transaction Value are specifically
withheld solely for purposes of satisfying any indemnity  obligations  which may
be owed by the  Shareholders  pursuant to Section  10.1  hereof  (the  "Retained
Indemnity  Shares").  The Retained  Shares shall reduce the Parent  Common Stock
distributed to the  Shareholders at Closing on a pro-rata basis according to the
percentage of the total Merger Consideration being received by each Shareholder.
The Retained Shares shall be subsequently distributed among the Shareholders and
Parent in accordance with the terms of Sections 3.2 and 10.4 hereof.

                  (b)  Cancellation.  Each share of Company Common Stock held in
the  treasury of the Company and each share of Company  Common Stock held by any
direct or indirect wholly owned Subsidiary of the Company,  if any,  immediately
prior to the  Effective  Time  shall,  by virtue of the Merger and  without  any
action on the part of the holder thereof,  cease to be outstanding,  be canceled
and retired without payment of any consideration therefor and cease to exist.

                  (c) Capital  Stock of Merger Sub.  Each share of common stock,
par value $.01 per share,  of Merger Sub ("Merger Sub Common  Stock") issued and
outstanding  immediately  prior to the  Effective  Time shall remain  issued and
outstanding.

                  (d)  Adjustments to Parent Common Stock.  The number of shares
of  Parent  Common  Stock  constituting  the  Merger   Consideration   shall  be
appropriately  adjusted to reflect fully the effect of any stock split,  reverse
split,  stock dividend  (including any dividend of securities  convertible  into
Parent Common  Stock),  reorganization,  reclassification,  recapitalization  or
other similar  change with respect to Parent Common Stock  occurring  (including
the record date thereof) after the date hereof and prior to the Effective Time.

         Section 3.2.  Adjustments to Merger Consideration.

                  (a)      The capitalized terms used in this Section shall have
the following meanings:

                                        3

<PAGE>

                  "Adjustment  Amount,"  which  may be a  positive  or  negative
number,  equals (i) the Adjustment  Percentage  Ratio times the Share Equivalent
Transaction  Value. The Adjustment Amount,  however,  is limited to no more than
positive fifteen percent (15%) of the Share Equivalent Transaction Value, and to
no less than negative fifteen percent (15%) of the Share Equivalent  Transaction
Value.

                  "Adjustment  Percentage  Ratio,"  which may be a  positive  or
negative  number,  is equal to (i)  Management  Fee  Contribution  Margin  minus
$988,000, divided by (ii) $988,000.

                  "Company  Existing  Practices"  means  the  practices  of  all
individual  physicians  which the  Company  managed as of the  Closing  Date (as
defined in Section 3.9) and listed on Exhibit B attached hereto.

                  "Determination  Period"  means the eighteen  (18) month period
beginning on July 1, 1999 and ending on December 31, 2000.

                  "Existing   Management   Agreements"   means  all   Management
Agreements  relating  to  Company  Existing  Practices  and  listed on Exhibit C
attached hereto.

                  "Management Fee Contribution Margin" or "MFCM" means an amount
equal to the  aggregate  of all Service Fees (as such term is defined in each of
the Existing  Management  Agreements)  earned in  accordance  with GAAP from the
Company Existing Practices under the Existing  Management  Agreements during the
Determination  Period,  regardless  of the party to whom such  Service  Fees are
payable,  less the Regional  Expenses (as  hereinafter  defined).  MFCM shall be
calculated in accordance  with  methodology  set forth in the schedule  attached
hereto as Exhibit D, with the revenues and expenses  included in the calculation
to be calculated in accordance with GAAP. In addition,  MFCM shall be calculated
and stated on an  annualized  basis,  but only after  subtracting  the aggregate
Service  Fees  during the  Determination  Period  that are  directly  related to
ancillary  services added to the Company Existing  Practices by Parent or Merger
Sub (excluding those ancillary  services  identified on Schedule 3.2(a) hereto).
The  specific  Regional  Expenses  that are directly  related to such  ancillary
services  added to the  Company  Existing  Practices  by Parent  or  Merger  Sub
(excluding those ancillary services  identified on Schedule 3.2(a) hereto) shall
not be deducted in  calculating  MFCM.  Notwithstanding  any  provision  of this
Section 3.2 or any other  provision of this Agreement,  appropriate  adjustments
shall be made in  calculating  MFCM to ensure that MFCM is not  decreased by (i)
any  adjustments  to the Balance  Sheet (as  hereinafter  defined)  accounts for
events  occurring  prior to June 30, 1999 or after December 31, 2000 or (ii) any
adjustments  which affect the  calculation of Net Working Capital (as defined in
Section 7.12).

<PAGE>

                  "Regional  Expenses"  shall  include  all the actual  expenses
incurred to operate or manage the Company Existing Practices that are not Clinic
and  Provider  Expenses  (as such  terms  are  defined  in each of the  Existing
Management  Agreements).  However,  during  the  Determination  Period,  for the
purpose of calculating  the Adjustment  Percentage  Ratio and MFCM, the Regional
Expenses  shall only  include  salaries  and wages and  related  benefits of the
regional controller,  accountant,  and regional  administrator and the following
expenses related to the regional corporate office: rent,  utilities,  insurance,

Syntera, Parent or Merger Sub.

                  "Replacement  Promissory  Note" means that certain  promissory
note, as hereafter amended,  substituted or replaced,  executed by Merger Sub at
the  Closing,  payable to  American  Physicians  Service  Group,  Inc.,  a Texas
corporation  ("APS"),  attached  hereto as Exhibit E, replacing all  outstanding
amounts under that certain  original  promissory note (the "Original  Promissory
Note") in the maximum principal amount of $3,000,000, dated November 1, 1998.

                  "Share Equivalent  Transaction Value" is equal to (i) 885,714,
plus  (ii)  the  outstanding  amount  under  the  Replacement   Promissory  Note
immediately following the Closing divided by $7.00.

<PAGE>

                  (b) On December  31,  2000 (the  "Calculation  Date"),  Parent
shall  cause  the  Surviving  Corporation  to  calculate  MFCM,  the  Adjustment
Percentage  Ratio  and the  Adjustment  Amount  (collectively,  the  "Adjustment
Calculations").  Within ninety (90) days following the Calculation  Date, Parent
shall deliver to each of the Shareholders a copy of the Adjustment Calculations,
and a clear written  statement  setting forth with  reasonable  specificity  the
Adjustment  Calculations and the values,  procedures and any assumptions used in
obtaining the Adjustment  Calculations.  The Shareholders  shall have 15 days to
object in writing to the Adjustment Calculations,  setting forth with reasonable
specificity any objections.  If Shareholders holding, in the aggregate, at least
25% of the previously  distributed  portion of the Merger  Consideration  do not
object  prior to the  expiration  of such 15 day  period,  then  the  Adjustment
Calculations shall be binding on all parties.  If Shareholders  holding,  in the
aggregate,  at least 25% of the  previously  distributed  portion  of the Merger
Consideration  object  prior  to the  expiration  of  such  15 day  period  (the
"Objecting Shareholders"),  then all the Shareholders and Parent shall negotiate
in good faith and

                                        5

<PAGE>

attempt to resolve the  disagreement.  Should such  negotiations not result in a
unanimous   agreement  within  one  hundred  twenty  (120)  days  following  the
Calculation  Date, then the matter shall be submitted to a big five  independent
accounting firm (other than the auditors of Parent,  the Surviving  Corporation,
or APS at the  time  of  such  dispute)  mutually  acceptable  to the  Objecting
Shareholders and Parent (a "Neutral Auditor"); provided that both Parent and the
Objecting  Shareholders  place in escrow cash equal to one-half of the estimated
fees of the Neutral  Auditor  pending the  outcome of the  disagreement.  If the
Objecting  Shareholders  and Parent are unable to agree on the Neutral  Auditor,
then  the  Objecting   Shareholders   and  Parent  shall  request  the  American
Arbitration Association to appoint the Neutral Auditor. The Neutral Auditor will
deliver  to all of the  Shareholders  and Parent a written  determination  (such
determination  to include a worksheet  setting  forth all material  calculations
used in arriving at such  determination) of the disputed items within sixty (60)
days of receipt  of the  disputed  items,  which  determination  shall be final,
binding and conclusive. If the Neutral Auditor's determination of the Adjustment
Amount  multiplied by $7 (the "Dollar  Adjustment  Amount") is within $25,000 of
Parent's  calculation of the Dollar Adjustment Amount (whether the difference is
positive or  negative),  all fees and expenses  relating to  appointment  of the
Neutral  Auditor and the work,  if any, to be performed  by the Neutral  Auditor
will be borne by the Objecting  Shareholders (or, if APS is one of the Objecting
Shareholders,   by  APS).  If  the  difference  between  the  Neutral  Auditor's
determination of the Dollar  Adjustment  Amount and Parent's  calculation of the
Dollar  Adjustment  Amount is greater  than  $25,000,  but less than or equal to
$100,000 (whether the difference is positive or negative), all fees and expenses
relating  to  appointment  of the Neutral  Auditor  and the work,  if any, to be
performed  by  the  Neutral   Auditor  will  be  borne  half  by  the  Objecting
Shareholders (or, if APS is one of the Objecting Shareholders,  by APS) and half
by Parent. If the difference between the Neutral Auditor's  determination of the
Dollar  Adjustment  Amount and  Parent's  calculation  of the Dollar  Adjustment
Amount  is  greater  than  $100,000  (whether  the  difference  is  positive  or
negative),  all fees and expenses relating to appointment of the Neutral Auditor
and the work,  if any,  to be  performed  by the Neutral  Auditor  will be borne
exclusively by Parent. The Adjustment  Calculations in this Section 3.2 are made
independent of the ownership of the Surviving Corporation after Closing.

                  (c) Upon the  later to occur of (i) June 30,  2001 or (ii) ten
(10)  days  following  agreement  on or  delivery  of  the  final,  binding  and
conclusive  Adjustment  Calculations  (the  "Distribution  Date"),  Parent shall
promptly  distribute  to the  Shareholders  from  escrow that number of Retained
Shares equal to (i) the agreed upon or conclusively determined Adjustment Amount
(which  may be  positive  or  negative),  plus (ii) 30% of the Share  Equivalent
Transaction  Value  (collectively,  the  amounts  in  clauses  (i) and  (ii) are
referred to as the  "Earnout  Distribution"),  minus  (iii) all Final  Suspended
Indemnified  Amounts and Pending  Indemnified Amounts (as such terms are defined
in Section  10.4) that are or may become  payable by the  Shareholders,  in each
case divided by 7;  provided,  however,  that in no event may the sum of clauses
(i) through (iii) be negative and;  provided,  further,  that if any Shareholder
exchanges  shares of Parent Common Stock to APS prior to the  Distribution  Date
pursuant to the terms of the Share Exchange Agreements (as hereinafter defined),
APS shall be entitled to receive the  Shareholder's  proportionate  share of the
Retained Shares.  Any and all of the Retained Shares that are not distributed to
the Shareholders on the Distribution Date shall be distributed to Parent, except
for that number of Retained Shares which

                                        6

<PAGE>

may reasonably be necessary to satisfy Pending  Indemnified Amounts (such shares
to be distributed to the appropriate  party or parties upon final  determination
of the Pending Indemnified Amounts).

                  (d) All share amounts and related share values  referred to in
this Section shall be  appropriately  adjusted upon the occurrence of any of the
events described in Section 3.1(d).

         Section 3.3. Anti-Dilution. If, during the Determination Period, Parent
issues  any  one or more  voting  equity  securities,  or any  other  securities
convertible  into or  exchangeable  for any voting equity  securities  (the "New
Securities"),  at a price (the  "Dilution  Price") of less than $7.00 per share,
then promptly  thereafter  Parent shall issue to the  Shareholders the number of
additional  shares of Parent  Common Stock,  without  requiring or receiving any
consideration therefore (the "Anti-Dilution Shares"), equal to (a) the number of
shares of Merger  Consideration  multiplied  by 7 and  divided  by the  Dilution
Price,  minus (b) the number of shares of Merger  Consideration.  In determining
the price at which New  Securities  have been issued,  the per share cash amount
received by Parent in return for the New  Securities  shall be used,  or, if the
issuance was not wholly for cash, the per share value expressly  assigned in any
document or  agreement  governing  the  issuance  shall be used,  or, if no such
document or agreement  exists,  the per share value  determined in good faith by
the  Board  of  Directors  of  Parent  shall  be  used.  For  purposes  of  this
calculation,  if Parent issues New Securities for less than $5.00,  the Dilution
Price shall be deemed to equal  $5.00 per share.  Seventy  percent  (70%) of the
Anti-Dilution  Shares  shall be issued to the  Shareholders  on a pro rata basis
according to the amount of Merger  Consideration  received by each  Shareholder.
Thirty  percent (30%) of the  Anti-Dilution  Shares shall be retained as part of
the Retained  Shares and  distributed  in accordance  with Sections 3.2 and 10.1
hereof.  All share amounts and related share values  referred to in this Section
shall  be  appropriately  adjusted  upon  the  occurrence  of any of the  events
described in Section 3.1(d).

         Section 3.4. Exchange of Certificates.  Immediately after the Effective
Time,  Parent will deliver to each Shareholder the Merger  Consideration  due to
the  Shareholder,  upon  surrender  by  the  Shareholder  of  a  certificate  or
certificates   which   immediately  prior  to  the  Effective  Time  represented
outstanding shares of Company Common Stock (the "Certificates") for cancellation
together with such other customary documents as may be required.

         Section 3.5. Stock  Transfer  Books.  At the Effective  Time, the stock
transfer  books of the  Company  shall be closed,  and there shall be no further
registration of transfers of the Company Common Stock  thereafter on the records
of the Company.

         Section 3.6. No Further  Ownership  Rights in Company Common Stock. The
Merger  Consideration  delivered  upon the  surrender  for exchange of shares of
Company Common Stock in accordance with the terms hereof shall be deemed to have
been  issued in full  satisfaction  of all rights  pertaining  to such shares of
Company Common Stock, and there shall be no further registration of transfers on
the records of the Surviving Corporation of shares of Company Common Stock which
were  outstanding  immediately  prior  to the  Effective  Time.  If,  after  the
Effective Time,  Certificates are presented to the Surviving Corporation for any
reason, they shall be canceled.

<PAGE>

         Section 3.7.  Tax and  Accounting  Consequences.  It is intended by the
parties  hereto that the Merger  shall  constitute a  reorganization  within the
meaning  of  Section  368 of the Code.  The  parties  hereto  hereby  adopt this
Agreement  as  a  "plan  of  reorganization"  within  the  meaning  of  Sections
1.368-2(g) and 1.368-3(a) of the United States Treasury Regulations.

         Section  3.8.  Taking of  Necessary  Action;  Further  Action.  Each of
Parent,  Merger Sub and the  Company  will take all such  reasonable  and lawful
action as may be necessary or  appropriate  in order to effectuate the Merger in
accordance  with this  Agreement as promptly as possible.  If, at any time after
the Effective  Time,  any such further action is necessary or desirable to carry
out the purposes of this  Agreement and to vest the Surviving  Corporation  with
full right, title and possession to all assets,  property,  rights,  privileges,
powers and  franchises of the Company and Merger Sub, the officers and directors
of the Company and Merger Sub in office  immediately prior to the Effective Time
are fully authorized in the name of their  respective  corporations or otherwise
to take, and will take, all such lawful and necessary action.

         Section 3.9.  Closing.  The closing (the "Closing") of the transactions
contemplated by this Agreement shall take place at a location mutually agreeable
to Parent and the Company in Houston,  Texas, as promptly as practicable (but in
any event within five (5) business days) following the date on which the last of
the  conditions  set forth in Article VIII is  fulfilled  or waived,  or at such
other time and place as Parent and the Company shall agree in writing.  The date
on which the Closing  occurs is referred to in this  Agreement  as the  "Closing
Date."

                                   ARTICLE IV

                               REPRESENTATIONS AND

                       WARRANTIES OF PARENT AND MERGER SUB

         Parent and  Merger Sub each  represent  and  warrant to the  Company as
follows:

         Section 4.1. Organization and Qualification.  Each of Parent and Merger
Sub is a corporation duly organized, validly existing and in good standing under
the laws of the state of its incorporation and has the requisite corporate power
and authority to own,  lease and operate its assets and  properties and to carry
on its  business as it is now being  conducted.  Parent is duly  qualified to do
business as a foreign  corporation and is in good standing in each  jurisdiction
in which the properties  owned,  leased,  or operated by it or the nature of the
business  conducted by it makes such qualification  necessary,  except where the
failure to be so qualified  and in good  standing  would not have,  or could not
reasonably be anticipated to have,  individually or in the aggregate, a Material
Adverse Effect (as defined in Exhibit A). True,  accurate and complete copies of
each of Parent's and Merger Sub's Certificate of Incorporation and Bylaws,  each
as amended and in effect on the date hereof,  have  heretofore been delivered to
the Company.  Merger Sub has not  commenced  business  since its  incorporation.
Merger Sub is not a party to or subject to any  agreement  or other  instrument,
other than its  Certificate  of  Incorporation,  Bylaws,  this Agreement and any
other  agreements  related  to the  Merger.  Merger  Sub does not own any assets
(tangible or intangible) other than the assets set

                                        8

<PAGE>

forth  on  Schedule  4.1  attached  hereto  and  Merger  Sub  does  not have any
liabilities,  accrued,  contingent or otherwise  (known or unknown,  asserted or
unasserted).

         program.

whole or in part, a predecessor of Parent and all of its former Subsidiaries and
their predecessors.

         Section  4.16.  Non-Competition  Agreements.  Except  as set  forth  on
Schedule 4.16,  neither Parent nor Merger Sub is a party to any agreement  which
purports to restrict or prohibit  either of them from,  directly or  indirectly,
engaging in any business currently engaged in by Parent. To Parent's  knowledge,
none of Parent's  or Merger  Sub's  shareholders,  officers,  directors,  or key
employees  is a party  to any  agreement  which,  by  virtue  of  such  person's
relationship  with Parent,  restricts  Parent or any  Subsidiary of Parent from,
directly or indirectly, engaging in any of the businesses described above.

         Section 4.17. Title to Assets.  Parent has good and marketable title in
fee  simple  to all its  real  property  and  good  title  to all its  leasehold
interests and other  properties,  as reflected in the most recent  balance sheet
included in the Parent  Financial  Statements,  except for properties and assets
that have been disposed of in the ordinary  course of business since the date of
the latest  balance sheet  included  therein,  free and clear of all  mortgages,
liens,  pledges,  charges or encumbrances of any nature  whatsoever,  except (i)
liens for current  taxes,  payments of which are not yet  delinquent,  (ii) such
imperfections  in title  and  easements  and  encumbrances,  if any,  as are not
substantial in character, amount or extent and do not detract from the value, or
interfere with the present use or  marketability of the property subject thereto
or affected thereby,  or otherwise impair Parent's  business  operations (in the
manner presently  carried on by Parent),  or (iii) any lien securing any debt or
obligation  described on Schedule  4.17 which is expressly  referenced  as being
secured.  To the Parent's  knowledge,  all leases under which Parent  leases any
real property have been delivered to the Company and are in good standing, valid
and effective in accordance with their respective terms, and there is not, under
any of such leases,  any existing default or event which with notice or lapse of
time  or  both  would  become  a  default  by or on  behalf  of  Parent  or  its
Subsidiaries, or by or on behalf of any third party.

or  commitment to which it is a party,  including  timely paying all interest on
its debt as such  interest  has become due and  payable.  Except as set forth on
Schedule  4.18,  there  are no  counterclaims  or  offsets  under  any  of  such

commissions  or  other  like  payments  in  connection  with  the   transactions
contemplated  hereby.  There is no claim for payment by Parent of any investment
banking  fees,  finder's  fees,  brokerage  or agent  commissions  or other like
payments in connection  with the  negotiations  leading to this Agreement or the
consummation of the transactions contemplated hereby.

         Section 4.20. Intellectual Property.  Parent has rights to use, whether
through  ownership,  licensing or otherwise,  all patents,  trademarks,  service
marks, trade names,  copyrights,  software,  trade secrets and other proprietary
rights  and  processes  that  are  material  to its  business  as now  conducted
(collectively the "Parent Intellectual Property Rights"). Except as set forth on
Schedule 4.20,  Parent does not own any patents.  Parent has no knowledge of any
infringement by any other person of any of Parent Intellectual  Property Rights,
and Parent has not  entered  into any  agreement  to  indemnify  any other party
against  any  charge  of  infringement  of any of Parent  Intellectual  Property
Rights.  Parent  has not and does  not  violate  or  infringe  any  intellectual
property   right  of  any  other  person,   and  Parent  has  not  received  any
communication  alleging that it violates or infringes the intellectual  property
right  of any  other  person.  Parent  has not  been  sued  for  infringing  any
intellectual  property right of another  person.  There is no claim or demand of
any  person  pertaining  to,  or any  proceeding  which is  pending  or,  to the
knowledge of Parent, threatened, that challenges the rights of Parent in respect
of any Parent  Intellectual  Property  Rights,  or that  claims that any default
exists  under  any  Parent  Intellectual  Property  Rights.  None of the  Parent
Intellectual  Property  Rights is  subject  to any  outstanding  order,  ruling,
decree, judgment or stipulation by or with any court, tribunal,  arbitrator,  or
other Governmental Authority.

         Section  4.21.  Relationships.  Except as set forth on  Schedule  4.21,
since  January  1, 1998,  Parent  has not  received  notice  from any  customer,
supplier or any party to any Contract  involving more than $50,000 annually with
Parent (each a "Parent Contract  Party") that such customer,  supplier or Parent
Contract Party intends to discontinue doing business with Parent, and since such
date,  no  customer,  supplier  or Parent  Contract  Party,  has  indicated  any
intention (a) to terminate its existing business relationship with Parent or (b)
not to continue its business  relationship  with Parent,  whether as a result of
the transactions contemplated hereby or otherwise. Except for the reorganization
of Parent on October 31, 1997,  Parent has not entered into or  participated  in
any related party transaction during the past three years.

with the business of Parent (a) any bribe,  kickback or other similar payment to
or from any domestic or foreign government or agency thereof or any other person

reflected  in said books and records were duly and validly  taken in  compliance
with the laws of the  applicable  jurisdiction  and no  meeting  of the board of
directors  of Parent or any  committee  thereof has been held for which  minutes
have been prepared and are not contained in the minute books. To the extent that
they  exist,  all  personnel  files,  reports,   strategic  planning  documents,
financial  forecasts,  accounting and tax records and all other records of every
type and  description  that relate to the business of Parent have been  prepared
and maintained in accordance  with good business  practices and applicable  laws
and regulations. All such books and records are located in the offices of Parent
or Parent Existing Practices.

securities'  laws,  and neither  Parent nor any agent  acting on its behalf will
take any action hereafter that would cause the loss of such exemption.

         Section 4.26. Staff Privileges.  Each of the Parent Existing  Practices
has staff  privileges at one or more hospitals,  and such staff  privileges have
not been revoked,  surrendered,  suspended or terminated, and except for routine

proceedings pending or threatened that may result in any revocation,  surrender,
suspension or termination  of such staff  privileges.  In addition,  to Parent's
knowledge,  there are no, and have not been, any facts,  conditions or incidents
that may result in any revocation,  surrender, suspension or termination of such
staff privileges.

contendere to,  patient abuse or  negligence,  or any other Medicare or Medicaid
related  offense,  and none of the  foregoing  persons has committed any offense

from the Medicare and Medicaid programs.

properties  and to carry  on its  business  as it is now  being  conducted.  The
Company is duly qualified to do business as a foreign corporation and is in good
standing in each jurisdiction in which the properties owned, leased, or operated
by it or the nature of the  business  conducted  by it makes such  qualification
necessary,  except  where the failure to be so  qualified  and in good  standing

in the aggregate,  a Material Adverse Effect. True, accurate and complete copies
of the Company's  Articles of Incorporation  and Bylaws,  each as amended and in
effect on the date hereof, have heretofore been delivered to Parent.

Agreement,    subscriptions,    options,    calls,    contracts,    commitments,
understandings,  restrictions,  arrangements,  rights or warrants, including any
right of  conversion  or exchange  under any  outstanding  security,  debenture,
instrument or other  agreement,  obligating  the Company or (to the knowledge of
the Company) any  Shareholder to issue,  deliver or sell, or cause to be issued,

stock rights,  co-sale or take along rights, or registration rights with respect
to any  securities  referred to in clauses (A) through (D) above.  Except as set
forth  on  Schedule  5.2(b),  there  are no  voting  trusts,  proxies  or  other
agreements  or  understandings  to which the Company or (to the knowledge of the
Company)  any  Shareholder  is a party or is bound with respect to the voting of
any shares of capital stock of the Company.

         Section 5.3. Subsidiaries.  Company does not have any Subsidiaries, nor
does the Company hold any equity interest in or control (directly or indirectly,
through  the  ownership  of  securities,  by

transactions  contemplated hereby. This Agreement has been approved by the Board
of  Directors  of the  Company  and the  Shareholders,  and no  other  corporate
proceedings  on the part of the Company or the  Shareholders  are  necessary  to

the Company of the  transactions  contemplated  hereby.  This Agreement has been
duly executed and delivered by the Company, and, assuming the due authorization,

legally  binding  agreement of the Company,  enforceable  against the Company in
accordance  with its terms,  except that such  enforcement may be subject to (i)
bankruptcy,  insolvency,  reorganization,   moratorium  or  other  similar  laws
affecting or relating to  enforcement  of creditors'  rights  generally and (ii)
general equitable principles.

                  (b)  The  execution  and  delivery  of this  Agreement  by the
Company and the  consummation  by the Company of the  transactions  contemplated
hereby in accordance with the terms hereof do not and will not, to the Company's
knowledge,  violate or result in a breach of any  provision  of, or constitute a
default  (or an event  which,  with  notice  or  lapse  of time or  both,  would
constitute a default)  under, or result in the termination of, or accelerate the
performance  required by, or result in a right of  termination  or  acceleration
under,  or result in the  creation  of any lien,  security  interest,  charge or
encumbrance upon any of the properties or assets of the Company under any of the
terms,  conditions or provisions of (i) the Articles of  Incorporation or Bylaws
of the Company, (ii) any statute, law, ordinance,  rule,  regulation,  judgment,

permit, concession, contract, lease or other instrument, obligation or agreement
of any kind to which the  Company is now a party or by which the  Company or any
of its respective  properties or assets may be bound or affected except,  in the
case of clauses  (ii) and  (iii),  for  matters as would not have,  or could not
reasonably be anticipated to have,  individually or in the aggregate, a Material
Adverse Effect or materially impair the ability of the Company to consummate the
transactions contemplated by this Agreement.

                  (c)  Except  for the Merger  Filings  in  connection  with the
Merger (the "Company Required Statutory Approvals"),  no declaration,  filing or
registration  with, or notice to, or authorization,  consent or approval of, any
governmental or regulatory  body or authority  (including,  without  limitation,
federal and state securities'  regulatory bodies) is necessary for the execution
and  delivery  of this  Agreement  by the Company  and the  Shareholders  or the
consummation  by  the  Company  and  the   Shareholders   of  the   transactions
contemplated  hereby,  other  than such  declarations,  filings,  registrations,
notices, authorizations, consents or approvals which, if not made

                                       23

                                       25

<PAGE>

Company or the Company Existing Practices,  at law or in equity, in any court or
before or by any Governmental Authority, and, to the Company's knowledge,  there
are no,  and  have  not  been  any,  facts,  conditions  or  incidents  that are
reasonably likely to result in any such actions, suits, proceedings (arbitration
or otherwise) or investigations. To the Company's knowledge, the Company and the
Company Existing Practices are not in default in respect of any judgment, order,
writ, injunction or decree of any court or other Governmental Authority.  Except
as set forth on Schedule  5.8, to the  knowledge of Company,  there have been no
disciplinary,  revocation or suspension  proceedings or similar types of claims,
actions or proceedings,  hearings or investigations  against the Company and the
Company  Existing  Practices,  and the  Company  does  not  know  of any  facts,
conditions  or  incidents  that  may  result  in any such  proceedings,  claims,

         Section 5.9.  Accounts  Receivable.  The Company Balance Sheet reflects
the amount,  as of the Company  Balance Sheet Date and  determined in conformity
with GAAP and on a basis  consistent  with the past  practices  employed  by the
Company,  of the Company's and the Company Existing  Practices  current accounts
receivable,  net of contractual  adjustments  arising out of  third-party  payor
arrangements  and  allowances  for bad debts  ("Company  Accounts  Receivable").
Schedule 5.9 reflects the amount of Company  Accounts  Receivable as of June 30,
1999. For all Company Accounts Receivable reflected on the Company Balance Sheet
there is a  corresponding  accounts  receivable  owed to the Company.  As of the
Closing  Date,  (i) the Company  knows of no reason  that the  Company  Accounts
Receivable  shall not be owned  solely by the  Company or (ii) the Company has a
security  agreement with the Company  Existing  Practices  pursuant to which the
Company  Existing  Practices have granted a security  interest to the Company in
the Company Accounts  Receivable in the amounts indicated in the Company Balance
Sheet which  represent  amounts  owed from the Company  Existing  Practices  for
services previously  rendered.  Except as set forth on Schedule 5.9, the Company
Accounts Receivable (i) are valid,  binding and legally enforceable  obligations
and are, subject to the preceding  sentence,  owned by the Company (or, prior to
the Closing Date, the Company  Existing  Practices)  free and clear of all liens
and encumbrances,  (ii) will not, to the Company's knowledge,  be subject to any
offset,  counterclaim or other adverse claim or defense,  except for contractual
adjustments arising out of third party payor arrangements, and (iii) may, to the
extent  permitted  by law, be sold and  transferred  to the Parent.  The Company
Accounts  Receivable  arose in the ordinary  course of business  consistent with
past  practices.  The Company  maintains  its  accounting  records in sufficient
detail to substantiate the Company Accounts Receivable  reflected on the Company
Balance Sheet and has given and will give to Parent full and complete  access to
those records,  including the right to make copies therefrom. Since December 31,
1998,  the Company has not changed any principle or practice with respect to the
recordation  of accounts  receivable,  or any material  collection,  discount or
write-off  policy or procedure,  and the Company has not sold or transferred any
Company  Accounts  Receivable.  To the  Company's  knowledge,  the Company is in
substantial  compliance with the terms and conditions of such third-party  payor
arrangements.

         Section 5.10.  No Violation of Law; Compliance with Agreements.

regulatory body or authority is pending or threatened,  nor has any governmental

performance or observance of any term or provision of, and no event has occurred
which, with lapse of time or action by a third party,  could result in a default
under,  (a) the charter,  bylaws or similar  organizational  instruments  of the
Company or (b) any contract,  commitment,  agreement,  indenture, mortgage, loan
agreement, note, lease, bond, license, approval or other instrument to which the
Company  is a party or by which it is bound or to which any of its  property  is
subject.

                  (c) The Company and the Company  Existing  Practices  have all
permits  (including  without  limitation   Environmental   Permits),   licenses,
franchises, variances, exemptions, orders and other governmental authorizations,
consents  and  approvals  required  or  necessary  to conduct  its  business  as
presently  conducted  (collectively,  the "Company  Permits").  To the Company's
knowledge,  the Company and the Company Existing  Practices are not in violation
of the terms of any  Company  Permit.  All such  permits,  licenses,  orders and
approvals are in full force and effect, and no suspension or cancellation of any
of them is pending or, to the knowledge of the Company, threatened. None of such
permits,  licenses,  orders or  approvals,  and no  application  for any of such
permits,  licenses,  orders  or  approvals  will be  adversely  affected  by the
consummation of the transactions contemplated by this Agreement. The Company and
(to the knowledge of the Company) the Company  Existing  Practices have not been
disciplined,  sanctioned or excluded from the Medicare program and have not been
subject to any plan of correction imposed by any professional review body.

insurance  been limited by any insurance  carrier that has carried,  or received
any  application  for,  any such  insurance  during  the last  three  years.  No

(to the Company's  knowledge) any  Shareholder is a party to any agreement which
purports  to  restrict or  prohibit  any of them from,  directly or  indirectly,
engaging in any business  currently engaged in by the Company.  To the Company's

included in the Company Financial  Statements,  except for properties and assets
that have been disposed of in the ordinary  course of business since the date of
the latest  balance sheet  included  therein,  free and clear of all  mortgages,
liens,  pledges,  charges or encumbrances of any nature  whatsoever,  except (i)
liens for current  taxes,  payments of which are not yet  delinquent,  (ii) such
imperfections  in title  and  easements  and  encumbrances,  if any,  as are not
substantial in character, amount or extent and do not detract from the value, or
interfere with the present use or  marketability of the property subject thereto
or affected thereby,  or otherwise impair the Company's business  operations (in
the manner presently carried on by the Company),  or (iii) any lien securing any
debt or obligation  described on Schedule 5.17 which is expressly  referenced as
being secured. To the Company's knowledge, all leases under which the Company

                                       32

         Section  7.6.  Exclusivity.  The  Company  acknowledges  that  the  due
diligence   and  other   investigations   permitted   herein  will  involve  the
expenditures  of  substantial  time and  expense  by  Parent.  In  consideration
thereof, the Company, on its own behalf and on behalf of its Affiliates,  agrees
that for a period of up to and  including  August 15, 1999,  it will not make or
encourage any offer or obtain any offer or otherwise  provide any  assistance in
aid of any  offer  for the  sale,  lease or  transfer  of all or any part of the
business  of the  Company  or of the  stock or  assets  of the  business  of the
Company,  to any  Person  other than  Parent.  Immediately  upon  receipt of any
unsolicited  offer,  the  Company  will  communicate  to Parent the terms of any
proposal or request for information and the identity of the parties involved.

         Section 7.7.  Confidentiality.  Without the express  written consent of
all of the  parties  hereto,  each of the parties  hereto  agrees to maintain in
confidence  and not disclose to any other  Person the terms of the  transactions
contemplated herein or the information delivered in connection with the proposed
due  diligence  investigation,  other than  disclosures  required  to obtain the
approvals  for  the  transactions  contemplated  hereby,  disclosures  to  those
professionals  and advisors who have a need to know,  disclosures of information
already available to the public or any other disclosures  required by applicable
law. In the event that either Parent or Merger Sub are at any time  requested or
required  (by  oral  questions,  interrogatories,  request  for  information  or
documents,  subpoena  or other  similar  process) to  disclose  any  information
supplied to it in connection with this transaction, such party agrees to provide
the other parties  hereto  prompt notice of such request so that an  appropriate
protective  order  may be sought  and/or  such  other  party may waive the first
party's compliance with the terms of this Section 7.7.

         Section 7.8.      Registration Rights.  Parent covenants and agrees as
follows:

                  (a)      Definitions.  For purposes of this Section, the

         Act  subsequently   adopted  by  the  SEC  that  permits  inclusion  or
         incorporation   of  substantial   information  by  reference  to  other
         documents filed by Parent with the SEC.

                  "Holder"  means  any  person  owning  or  having  the right to
         acquire  Registrable  Securities or any assignee  thereof in accordance
         with subsection (i) of this Section.

                  "Initial   Offering"  means  Parent's  first  firm  commitment
         underwritten  public  offering  of its Parent  Common  Stock  under the
         Securities Act.

               "1934 Act" means the Securities Exchange Act of 1934, as amended.

                                       42

<PAGE>

                  "register,"   "registered,"  and  "registration"  refer  to  a
         registration effected by preparing and filing a registration  statement
         or similar  document in  compliance  with the  Securities  Act, and the
         declaration or ordering of effectiveness of such registration statement
         or document.

                  "Registrable  Securities" means the Parent Common Stock issued
         to the  Shareholders  pursuant  to this  Agreement  and any  additional
         shares of Parent Common Stock issued to the Shareholders  pursuant to a

         securities  convertible  into  Parent  Common  Stock),  reorganization,
         reclassification, recapitalization or other similar change with respect
         to  Registrable  Securities,  excluding  in  all  cases,  however,  any
         Registrable  Securities  sold by a person in a transaction in which his
         rights under this Section are not assigned.

                  "SEC" shall mean the Securities and Exchange Commission.

                  (b) Parent Registration.  Except as otherwise provided in this
Section (but without any  obligation  under this  Agreement to do so), if Parent
proposes to register  (including  for this  purpose a  registration  effected by
Parent for  stockholders  other than the Holders,  whether or not required under
another  agreement)  any of the Parent Common Stock under the  Securities Act in
connection  with  the  public   offering  of  such  securities   (other  than  a
registration  relating  solely to the sale of  securities to  participants  in a
Parent  stock plan, a  registration  relating to a corporate  reorganization  or
other  transaction  under Rule 145 of the Securities  Act, a registration on any
form  that  does not  include  substantially  the same  information  as would be
required to be included in a  registration  statement  covering  the sale of the
Registrable Securities,  or a registration in which the only Parent Common Stock
being  registered  is Parent  Common  Stock  issuable  upon  conversion  of debt
securities that are also being registered),  Parent shall,  within ten (10) days
thereafter,  give each  Holder  written  notice of such  registration.  Upon the
written  request of each Holder,  provided  said request is given within  twenty
(20) days after mailing of the notice required of Parent under this  subsection,
Parent shall,  subject to the limits set forth in this Section, use commercially
reasonable efforts to cause to be registered under the Securities Act all of the
Registrable  Securities  that each such Holder has  requested to be  registered;
provided that:

                           (i)  Parent  shall  have the  right to  terminate  or
         withdraw any  registration  initiated by it under this subsection prior
         to the effectiveness of such registration whether or not any Holder has
         elected to include  securities  in such  registration.  The expenses of
         such withdrawn registration shall be borne by Parent in accordance with
         subsection (e) of this Section; and

                           (ii) In  connection  with any  offering  involving an
         underwriting  of shares of Parent  Common  Stock,  Parent  shall not be
         required  under  this   subsection  to  include  any  of  the  Holders'
         securities  in such  underwriting  unless  they accept the terms of the
         underwriting  as  agreed  upon  between  Parent  and  the  underwriters
         selected   by  it  (or  by  other   persons   entitled  to  select  the
         underwriters)  and enter into an  underwriting  agreement  in customary
         form with an underwriter or underwriters selected by Parent, and then

                                       43

<PAGE>

         only in such  quantity  as the  underwriters  determine  in their  sole
         discretion  will not  jeopardize the success of the offering by Parent.
         If the total amount of securities,  including  Registrable  Securities,
         requested by stockholders  to be included in such offering  exceeds the
         amount of  securities  that the  underwriters  determine  in their sole
         discretion is compatible with the success of the offering,  then Parent
         shall be  required to include in the  offering  only the number of such
         securities,  including  Registrable  Securities,  that the underwriters
         determine in their sole  discretion  will not jeopardize the success of
         the offering  (the  securities so included to be  apportioned  pro rata
         among the selling  Holders  according to the total amount of securities
         entitled to be included therein owned by each selling Holder or in such
         other  proportions  as shall  mutually  be  agreed  to by such  selling
         Holders);  provided,  however, in no event shall Registrable Securities
         held by a Holder be included in such registration statement (i) if such
         offering is the initial  public  offering  of Parent's  securities,  in
         which case the  selling  Holders'  securities  may be  excluded  if the
         underwriters make the determination  described above or (ii) unless all
         of  the  following   securities  are  included  in  such   Registration
         Statement:  (x) all shares of capital stock of Parent which are subject
         to  registration  rights  as of the  Closing  Date;  (y) all  shares of
         capital  stock of Parent which are held by officers of Parent that hold
         an office on the Closing  Date;  and (z) all shares of capital stock of
         Parent that are issued with  registration  rights after the date hereof
         in connection  with a cash financing  transaction (or any other type of
         transaction approved in writing by a majority of the Shareholders) with
         Parent or any  Subsidiary  of Parent.  For purposes of the  immediately
         preceding  parenthetical  concerning  apportionment,  for  any  selling
         stockholder  that is a Holder of  Registrable  Securities and that is a
         partnership  or  corporation,   the  partners,   retired  partners  and
         stockholders  of such Holder,  or the estates and family members of any
         such  partners  and retired  partners and any trusts for the benefit of
         any of the foregoing  persons  shall be deemed to be a single  "selling
         Holder," and any pro rata reduction with respect to such selling Holder
         shall be based  upon the  aggregate  amount of  Registrable  Securities
         owned by all such related entities and individuals.

                           (iii)  With  respect to any  underwriting  of shares,
         Parent shall have the right to designate  the managing  underwriter  or
         underwriters.

                  (c)  Obligations  of  Parent.  Whenever  required  under  this
Section 7.8 to effect the  registration  of any Registrable  Securities,  Parent
shall, as expeditiously as reasonably possible:

                           (i)  prepare  and file  with  the SEC a  registration
         statement  with  respect  to such  Registrable  Securities  and use its
         commercially reasonably efforts to cause such registration statement to
         become  effective;  provided,  however,  that in  connection  with  any
         proposed  registration intended to permit an offering of any securities
         from time to time (i.e.,  a "Shelf  Registration"),  Parent shall in no
         event be obligated to cause any such  registration to remain  effective
         for more than one-hundred twenty (120) days;

                           (ii)  prepare  and file with the SEC such  amendments
         and supplements to such registration

                                       44

<PAGE>

         statement and the prospectus used
         in connection with such  registration  statement as may be necessary to
         comply with the  provisions of the  Securities  Act with respect to the
         disposition of all securities covered by such registration statement;

                           (iii)  furnish to the Holders  such numbers of copies
         of a prospectus, including a preliminary prospectus, in conformity with
         the  requirements  of the Securities  Act, and such other  documents as
         they may reasonably  request in order to facilitate the  disposition of
         Registrable Securities owned by them;

                           (iv) use commercially  reasonable efforts to register
         and qualify the securities covered by such registration statement under
         such other  securities or Blue Sky laws of such  jurisdictions as shall
         be necessary  for the  distribution  of the  securities  covered by the
         registration  statement,  provided that Parent shall not be required in
         connection  therewith  or  as a  condition  thereto  to  qualify  to do
         business or to file a general consent to service of process in any such
         states or  jurisdictions  and further  provided that  (anything in this
         Agreement to the contrary  notwithstanding  with respect to the bearing
         of  expenses)  if any  jurisdiction  in which the  securities  shall be
         qualified  shall require that expenses  incurred in connection with the
         qualification  of the  securities  in that  jurisdiction  be  borne  by
         selling  stockholders,  then such expenses  shall be payable by selling
         stockholders pro rata, to the extent required by such jurisdiction;

                           (v) in the event of any underwritten public offering,
         enter into and perform its obligations under an underwriting agreement,
         in usual and  customary  form,  with the managing  underwriter  of such
         offering;

                           (vi)  notify each  Holder of  Registrable  Securities
         covered by such  registration  statement  at any time when a prospectus
         relating  thereto is required to be delivered  under the Securities Act
         or the  happening  of any  event as a result  of which  the  prospectus
         included in such registration statement, as then in effect, includes an
         untrue  statement of a material  fact or omits to state a material fact
         required  to be stated  therein  or  necessary  to make the  statements
         therein not misleading in the light of the circumstances then existing;

                           (vii)  use  reasonable  efforts  to  cause  all  such
         Registrable  Securities  registered  pursuant hereunder to be listed on
         each securities  exchange on which similar  securities issued by Parent
         are then listed; and

                           (viii) provide a transfer agent and registrar for all
         Registrable  Securities registered hereunder and a CUSIP number for all
         such Registrable Securities,  in each case not later than the effective
         date of such registration.

                  (d) Information from Holder. It shall be a condition precedent
to the  obligations  of Parent to take any action  pursuant to this Section with
respect to the  Registrable  Securities  of any selling  Holder that such Holder
shall furnish to Parent such information regarding itself, the Registrable

                                       45

<PAGE>

Securities held by it, and the intended method of disposition of such securities
as shall be required to effect the  registration  of such  Holder's  Registrable
Securities.

                  (e)  Expenses  of   Registration.   All  reasonable   expenses
(excluding   underwriting  discounts  and  brokerage  commissions)  incurred  in
connection with registrations,  filings or qualifications pursuant to subsection
(b) of this Section, including without limitation, all registration,  filing and
qualification  fees,  printers' and accounting  fees, fees and  disbursements of
counsel for Parent and the reasonable fees and  disbursements of one counsel for
the selling Holders shall be borne by Parent.

                  (f) Delay of  Registration.  No Holder shall have any right to
obtain  or seek  an  injunction  restraining  or  otherwise  delaying  any  such
registration as the result of any  controversy  that might arise with respect to
the interpretation or implementation of this Section.

                  (g) Indemnification. In the event any  Registrable  Securities
are included in a registration  statement  under this Section:

                           (i) To the  extent  permitted  by  law,  Parent  will
         indemnify  and hold  harmless  each  Holder,  the partners or officers,
         directors  and   stockholders   of  each  Holder,   legal  counsel  and
         accountants  for  each  Holder,  any  underwriter  (as  defined  in the
         Securities  Act) for such Holder and each person,  if any, who controls
         such Holder or underwriter  within the meaning of the Securities Act or
         the 1934 Act, against any losses, claims, damages or liabilities (joint
         or several) to which they may become subject under the Securities  Act,
         the 1934 Act or any state  securities  laws,  insofar  as such  losses,
         claims,  damages,  or liabilities (or actions in respect thereof) arise
         out of or are based upon any of the following statements,  omissions or
         violations  (collectively a "Violation"):  (A) any untrue  statement or
         alleged  untrue   statement  of  a  material  fact  contained  in  such
         registration  statement,  including any preliminary prospectus or final
         prospectus  contained therein or any amendments or supplements thereto,
         (B) the omission or alleged  omission of a material fact required to be
         stated  therein,  or  necessary  to make  the  statements  therein  not
         misleading,  or (C) any violation or alleged violation by Parent of the
         Securities Act, the 1934 Act, any state  securities laws or any rule or
         regulation  promulgated  under the Securities  Act, the 1934 Act or any
         state  securities  laws;  and Parent will  reimburse  each such Holder,
         underwriter  or  controlling  person  for any  legal or other  expenses
         reasonably  incurred  by  them  in  connection  with  investigating  or
         defending any such loss, claim, damage,  liability or action; provided,
         however,  that the  indemnity  agreement  contained in this  subsection
         (g)(i) shall not apply to amounts paid in  settlement of any such loss,
         claim,  damage,  liability  or action if such  settlement  is  effected
         without the consent of Parent (which consent shall not be  unreasonably
         withheld),  nor  shall  Parent  be liable in any such case for any such
         loss, claim,  damage,  liability or action to the extent that it arises
         out of or is based upon a Violation that occurs in reliance upon and in
         conformity  with written  information  furnished  expressly  for use in
         connection with such  registration  by any such Holder,  underwriter or
         controlling  person;  provided  further,  however,  that the  foregoing
         indemnity agreement with respect to any

                                       46

<PAGE>

         preliminary  prospectus  shall
         not inure to the  benefit of any Holder or  underwriter,  or any person
         controlling such Holder or underwriter,  from whom the person asserting
         any such losses, claims, damages or liabilities purchased shares in the
         offering,  if a copy of the prospectus (as then amended or supplemented
         if Parent shall have furnished any  amendments or supplements  thereto)
         was not sent or given by or on behalf of such Holder or  underwriter to
         such person, if required by law so to have been delivered,  at or prior
         to the written  confirmation  of the sale of the shares to such person,
         and if the prospectus (as so amended or supplemented)  would have cured
         the defect giving rise to such loss, claim, damage or liability.

                           (ii) To the extent  permitted  by law,  each  selling
         Holder will indemnify and hold harmless Parent,  each of its directors,
         each of its officers who has signed the  registration  statement,  each
         person,  if  any,  who  controls  Parent  within  the  meaning  of  the
         Securities  Act,  legal  counsel  and   accountants  for  Parent,   any
         underwriter,  any other Holder selling  securities in such registration
         statement and any controlling  person of any such  underwriter or other
         Holder,  against any losses,  claims,  damages or liabilities (joint or
         several)  to which any of the  foregoing  persons  may become  subject,
         under the Securities  Act, the 1934 Act or any state  securities  laws,
         insofar as such losses,  claims,  damages or liabilities (or actions in
         respect thereto) arise out of or are based upon any Violation,  in each
         case to the extent (and only to the extent) that such Violation  occurs
         in reliance upon and in conformity with written  information  furnished
         by such Holder expressly for use in connection with such  registration;
         and  each  such  Holder  will  reimburse  any  person  intended  to  be
         indemnified pursuant to this subsection (g)(ii), for any legal or other
         expenses   reasonably  incurred  by  such  person  in  connection  with
         investigating or defending any such loss, claim,  damage,  liability or
         action;  provided,  however,  that the indemnity agreement contained in
         this  subsection  (g)(ii) shall not apply to amounts paid in settlement
         of any such loss, claim, damage, liability or action if such settlement
         is effected  without the consent of the Holder (which consent shall not
         be  unreasonably  withheld),  provided  that  in  no  event  shall  any
         indemnity  under this  subsection  (g)(ii) exceed the net proceeds from
         the offering received by such Holder.

                           (iii) Promptly after receipt by an indemnified  party
         under this  subsection (g) of notice of the  commencement of any action
         (including any governmental  action), such indemnified party will, if a
         claim in respect thereof is to be made against any  indemnifying  party
         under this subsection (g), deliver to the indemnifying  party a written
         notice of the  commencement  thereof and the  indemnifying  party shall
         have the right to participate  in, and, to the extent the  indemnifying
         party so desires,  jointly with any other  indemnifying party similarly
         noticed,   to  assume  the  defense   thereof  with  counsel   mutually
         satisfactory  to the parties;  provided,  however,  that an indemnified
         party  (together  with  all  other  indemnified  parties  that  may  be
         represented  without  conflict by one counsel)  shall have the right to
         retain one separate  counsel,  with the fees and expenses to be paid by
         the indemnifying  party, if representation of such indemnified party by
         the counsel retained by the  indemnifying  party would be inappropriate
         due to actual or potential differing interests between such indemnified

                                       47

<PAGE>

         party  and  any  other  party  represented  by  such  counsel  in  such
         proceeding.  The failure to deliver written notice to the  indemnifying
         party within a reasonable time of the  commencement of any such action,
         if prejudicial to its ability to defend such action, shall relieve such
         indemnifying party of any liability to the indemnified party under this
         subsection  (g), but the omission so to deliver  written  notice to the
         indemnifying  party will not  relieve it of any  liability  that it may
         have to any indemnified party otherwise than under this subsection (g).

                           (iv)  Notwithstanding  the  foregoing,  to the extent
         that the provisions on  indemnification  and contribution  contained in
         the  underwriting   agreement  entered  into  in  connection  with  the
         underwritten  public  offering  are  in  conflict  with  the  foregoing
         provisions, the provisions in the underwriting agreement shall control.

                           (v) The  obligations of Parent and Holders under this
         subsection  (g)  shall  survive  the  completion  of  any  offering  of
         Registrable  Securities in a registration  statement under this Section
         7.8, and otherwise.

                  (h) Reports Under Securities Exchange Act of 1934. With a view
to making  available to the Holders the benefits of Rule 144  promulgated  under
the  Securities  Act and any other rule or regulation of the SEC that may at any
time  permit a  Holder  to sell  securities  of  Parent  to the  public  without
registration or pursuant to a registration on Form S-3, Parent agrees that while
it has a class of equity  securities  registered under the 1934 Act, it will use
its commercially reasonable efforts to:

                           (i) make and keep public  information  available,  as
         those  terms are  understood  and defined in SEC Rule 144, at all times
         after the effective date of the Initial Offering;

                           (ii)     file with the SEC in a timely manner all
         reports and other documents required of Parent under the Securities Act
         and the 1934 Act; and

                           (iii)  furnish to any  Holder,  so long as the Holder
         owns any Registrable  Securities,  forthwith upon request (A) a written
         statement   by  Parent  that  it  has  complied   with  the   reporting
         requirements  of SEC Rule 144 (at any time after ninety (90) days after
         the  effective  date  of the  first  registration  statement  filed  by
         Parent),  the Securities Act and the 1934 Act (at any time after it has
         become subject to such reporting requirements), or that it qualifies as
         a registrant  whose  securities may be resold  pursuant to Form S-3 (at
         any time after it so  qualifies),  (B) a copy of the most recent annual
         or quarterly  report of Parent and such other  reports and documents so
         filed by Parent,  and (C) such other  information  as may be reasonably
         requested in availing any Holder of any rule or  regulation  of the SEC
         that permits the selling of any such securities without registration or
         pursuant to such form.

                  (i)  Assignment of  Registration  Rights.  The rights to cause
Parent to register  Registrable  Securities  pursuant to this Section 7.8 may be
assigned (but only with all related  obligations) by a Holder to a transferee or
assignee of such securities that (i) is a subsidiary,  parent, partner,  limited
partner,  retired partner or stockholder of a Holder,  (ii) is a Holder's family
member or trust for the  benefit of an  individual  Holder,  or (iii) after such
assignment or transfer,  holds at least 25,000 shares of Registrable  Securities
(subject  to  appropriate   adjustment  for  stock  splits,   stock   dividends,
combinations  and other  recapitalizations),  provided:  (x) Parent is, within a
reasonable  time after such transfer,  furnished with written notice of the name
and address of such  transferee or assignee and the  securities  with respect to
which  such  registration  rights are being  assigned;  (y) such  transferee  or
assignee  agrees  in  writing  to be  bound  by and  subject  to the  terms  and
conditions  of the  Investor  Rights  Agreement  and this  Agreement,  including
without  limitation,  the provisions of subsection (l) of this Section;  and (z)
such assignment  shall be effective only if immediately  following such transfer
the further  disposition  of such  securities  by the  transferee or assignee is
restricted under the Securities Act.

                  (j) Limitations on Subsequent  Registration Rights.  Except as
provided in the following  sentence,  from and after the date of this Agreement,
Parent shall not, without the prior written consent of the Holders of two-thirds
of the Registrable  Securities,  which will not be unreasonably withheld,  enter
into any agreement  with any holder or  prospective  holder of any securities of
Parent that would allow such holder or  prospective  holder (i) to include  such
securities  in any  registration  filed under  subsection  (b) of this  Section,
unless under the terms of such agreement,  such holder or prospective holder may
include such  securities  in any such  registration  only to the extent that the
inclusion  of such  securities  will not reduce  the  amount of the  Registrable
Securities  of the Holders that are included or (ii) to demand  registration  of
their  securities.   Notwithstanding  the  foregoing,   the  parties  agree  and
acknowledge  that  the   above-referenced   restriction  shall  not  affect  any
registration  rights  granted prior to the Closing Date,  and shall not prohibit
Parent from  granting  registration  rights  after the Closing  Date  (including
rights that may have priority  over those granted  pursuant to this Section 7.8)
with respect to the following securities:  (y) shares of capital stock of Parent
which are held by officers  of Parent  that hold an office on the Closing  Date;
and (z) shares of capital stock of Parent that are issued in  connection  with a
cash financing transaction with Parent or any Subsidiary of Parent.

                  (k) "Market  Stand-Off"  Agreement.  Each Holder hereby agrees
that it will not, without the prior written consent of the managing underwriter,
during the period  commencing  on the date of the final  prospectus  relating to
Parent's  initial public offering and ending on the date specified by Parent and
the managing  underwriter  (such  period not to exceed one hundred  eighty (180)
days) (i) lend,  offer,  pledge,  sell,  contract  to sell,  sell any  option or
contract to purchase, purchase any option or contract to sell, grant any option,
right or warrant to purchase,  or otherwise  transfer or dispose of, directly or
indirectly, any shares of Parent Common Stock or any securities convertible into
or exercisable or  exchangeable  for Parent Common Stock (whether such shares or
any such securities are then owned by the Holder or are thereafter acquired), or
(ii) enter into any swap or other  arrangement  that  transfers  to another,  in
whole or in part,  any of the economic  consequences  of ownership of the Parent
Common Stock, whether any such transaction described

                                       49

<PAGE>

in clause (i) or (ii) above
is to be settled by delivery of Common Stock or such other  securities,  in cash
or otherwise.  The foregoing  provisions of this subsection  shall apply only to
Parent's  initial public offering of equity  securities,  shall not apply to the
sale of any shares to an underwriter pursuant to an underwriting agreement,  and
shall only be  applicable  to the  Holders if all  officers  and  directors  and
greater  than five  percent  (5%)  stockholders  of Parent  enter  into  similar
agreements. The underwriters in connection with Parent's initial public offering
are intended  third party  beneficiaries  of this  subsection and shall have the
right,  power and authority to enforce the provisions hereof as though they were
a party hereto.  In order to enforce the foregoing  covenant,  Parent may impose
stop-transfer  instructions  with respect to the Registrable  Securities of each
Holder  (and the  shares or  securities  of every  other  person  subject to the
foregoing restriction) until the end of such period. _

                  (l)  Termination of  Registration  Rights.  No Holder shall be
entitled to exercise any right  provided for in this Section 7.8 after three (3)
years following the  consummation of the Initial  Offering or, as to any Holder,
such earlier time at which all  Registrable  Securities held by such Holder (and
any affiliate of the Holder with whom such Holder must aggregate its sales under
Rule 144) can be sold in any three  (3)-month  period  without  registration  in
compliance with Rule 144 of the Securities Act.

         Section  7.9.  Share  Exchange   Agreements.   Parent  and  Merger  Sub
acknowledge  the  existence  and  binding  and  enforceable  nature of the Share
Exchange  Agreements  and that  counsel to Parent  and Merger Sub has  carefully
reviewed  each Share  Exchange  Agreement.  Each of Parent and Merger Sub agrees
that (i) it has no rights to  enforce  any of the  provisions  of, and is not an
intended third party beneficiary under, any of the Share Exchange Agreements and
(ii) that it will take no action which  jeopardizes  the binding and enforceable
nature of the Share Exchange  Agreements and/or interfere with any of the rights
of any person or entity that is a party to any of the Share Exchange Agreements.

         Section  7.10.  Employee  Benefits.  Effective as of the  Closing,  all
welfare plans (as defined in ERISA Section 3(1)) provided, sponsored, or offered
by APS and made available to the Company and its employees  immediately prior to
the Closing ("APS Welfare  Plans") will continue to be made  available by APS to
the Surviving  Corporation  and its employees in the same manner and to the same
extent that such APS  Welfare  Plans were made  available  by APS to the Company
immediately prior to the Closing (except that the Surviving  Corporation may add
newly hired  employees  for coverage  under such APS Welfare  Plans).  For these
purposes, APS shall continue to make available all such APS Welfare Plans to the
Surviving  Corporation through December 31, 1999, or, if earlier, such date that
the Surviving  Corporation provides written notice to APS to modify or terminate
coverage  under  one or more  such APS  Welfare  Plans.  All  fees and  expenses
relating to the APS Welfare Plans shall be consistent with the fees and expenses
incurred by the Company prior to Closing on a per participant basis, and will be
paid by the Surviving  Corporation to APS.  Notwithstanding  the foregoing,  APS
shall not be liable  for any  liability  arising  under  COBRA  with  respect to
employees of the Surviving Corporation who are terminated by the Surviving

                                       50

<PAGE>

Corporation  after  the  Closing  Date,  and  the  Surviving  Corporation  shall
reimburse APS to the extent that APS incurs any such liability.

         Section 7.11.  Filings.  Parent or Merger Sub shall timely file all
forms,  notices,  or other filings  required by any state or federal securities'
regulator.

         Section 7.12.  Net Working Capital.

                  (a)  Initial  Principal  Amount.  Merger Sub hereby  agrees to
execute the Replacement  Promissory Note at the Closing.  Immediately  following
the Closing,  the principal amount outstanding under the Replacement  Promissory
Note shall equal all  outstanding  amounts  (including  principal  and interest)
under the Original Promissory Note at the time of Closing plus the First Advance
(as defined under  Section  7.13(a)),  if any;  provided,  however,  that if the
principal  amount of the  Replacement  Promissory  Note as of the  Closing  Date
exceeds  $2,000,000  (the  "Cap"),  there shall be either (i) a reduction in the
principal  amount of the  Replacement  Promissory Note by an amount equal to the
difference  between the  Replacement  Promissory  Note and the Cap (the "Closing
Credit  Amount"),  or (ii) an offset against  interest due under the Replacement
Promissory  Note in an amount equal to the Closing Credit  Amount,  which offset
shall be  taken  against  each  payment  of  accrued  and  unpaid  interest  due
thereunder until the Closing Credit Amount shall be paid in full and;  provided,
further, that any offset or reduction under subsection (a)(i) and (a)(ii) above,
plus any offset or reduction  under  Section  7.13(b)(ii)(y)  and (z),  shall be
deemed to have occurred prior to June 30, 1999 for purposes of  calculating  Net
Working  Capital under this Section 7.12. APS shall have the right to select one
of the  above-referenced  methodologies  with  respect  to such  Closing  Credit
Amount,  which  amount must be  disclosed  in writing to Parent on or before the
Closing Date. If APS does not make a selection  within thirty (30) days,  Parent
shall  then have the right to select one of the  above-referenced  methodologies
with respect to such Closing Credit  Amount,  which must be disclosed in writing
to APS on or before the date on which  first  interest  payment is due under the
Replacement  Promissory  Note. The payment terms of the  Replacement  Promissory
Note shall  include  interest  only  payments  for a period of twenty  four (24)
months immediately following the Closing Date, payable quarterly.

                  (b) Net Working  Capital.  For purposes of this Section  7.12,
"Net Working  Capital"  means an amount equal to the actual  current assets less
actual  current   liabilities  of  the  Company   existing  on  June  30,  1999,
(irrespective of when such amount is calculated),  determined in accordance with
GAAP (except as adjusted on Exhibit F hereto), and may be a positive or negative
number.

                  (c) First Actual Net Working  Capital  Calculation.  Within 90
days after the Closing  Date,  Parent shall cause the Surviving  Corporation  to
prepare a balance  sheet (the "First Net Working  Capital  Closing  Date Balance
Sheet") of the  Company as of June 30,  1999,  including  a  computation  of the
actual Net Working Capital (the "First Actual Net Working  Capital").  The First
Net Working  Capital  Closing Date Balance Sheet shall be prepared in accordance
with GAAP (except as adjusted on Exhibit F hereto) and agreed upon by APS and

                                       51

<PAGE>

Parent. Any disagreements involving the First Actual Net Working Capital Closing
Date Balance Sheet or the  calculation  of the First Actual Net Working  Capital
shall be resolved in accordance  with the procedure set forth in Section 7.12(e)
below.  If the First Actual Net Working  Capital is greater than  $700,000  (the
"Threshold"), then no adjustment shall be made or other action taken pursuant to
this  subsection  (c). If the First Actual Net Working  Capital is less than the
Threshold,  there shall be either (i) a reduction in the principal amount of the
Replacement  Promissory  Note by an amount equal to the  difference  between the
First Actual Net Working Capital and the Threshold (the "First Credit  Amount"),
or (ii) an offset against interest due under the Replacement  Promissory Note in
an amount equal to the First Credit Amount,  which offset shall be taken against
each  payment of accrued  and unpaid  interest  due  thereunder  until the First
Credit  Amount shall be paid in full.  APS shall have the right to select one of
the  above-referenced  methodologies  with respect to such First Credit  Amount,
which must be disclosed in writing to Parent within ten (10) business days after
such amount is agreed upon or finally  determined under subsection (e) below. If
APS does not make a selection  within such ten (10) business day period,  Parent
shall  then have the right to select one of the  above-referenced  methodologies
with respect to such First Credit Amount,  which must be disclosed in writing to
APS on or before  the date on which the next  interest  payment is due under the
Replacement Promissory Note. Any reduction or offset pursuant to this subsection
(c) shall be effective contemporaneously with such determination.

                  (d) Second  Actual Net  Working  Capital  Calculation.  On the
Calculation  Date,  Parent shall cause the  Surviving  Corporation  to prepare a
second  balance  sheet (the  "Second Net Working  Capital  Closing  Date Balance
Sheet") of the  Company as of June 30,  1999,  including  a  computation  of the
actual Net Working Capital (the "Second Actual Net Working Capital"). The Second
Net Working  Capital  Closing Date Balance Sheet shall be prepared in accordance
with GAAP  (except  as  adjusted  on Exhibit F hereto).  Any  objections  to the
calculation  of the Second  Actual Net  Working  Capital  shall be  resolved  in
accordance with the procedure set forth in Section 7.12(e) below.

                            (i) If the  Second  Net  Working  Capital is greater
         than  the  First  Net  Working  Capital  (such  difference  hereinafter
         referred to as the "Surplus"), there shall be either (A) an increase in
         the principal  amount of the  Replacement  Promissory Note by an amount
         equal to the lesser of the Surplus or the First Credit  Amount,  or (B)
         an increase in the interest due under the  Replacement  Promissory Note
         (but not in excess of the maximum  non-usurious  rate of interest  that
         may be charged under applicable law),  beginning with the next interest
         payment due thereunder and continuing until the First Credit Amount has
         been paid in full,  in an amount  equal to the lesser of the Surplus or
         the First Credit Amount; provided, however, that there shall be no such
         increase  if both the First Net  Working  Capital  and the  Second  Net
         Working Capital exceed the Threshold. The methodology used in effecting
         any increase  pursuant to this subsection  shall be consistent with the
         methodology actually applied by the parties pursuant to Section 7.12(a)
         (but only to the extent not  prohibited  by the  immediately  preceding
         parenthetical).  Any increase  pursuant to this subsection (d)(i) shall
         be effective contemporaneously with such determination.

                                       52

<PAGE>

                           (ii) If the Second Net  Working  Capital is less than
         the First Net Working Capital, there shall be either (A) a reduction in
         the principal  amount of the  Replacement  Promissory Note by an amount
         equal to the lesser of the  Threshold  and the First Actual Net Working
         Capital,  minus the Second Net  Working  Capital  (the  "Second  Credit
         Amount"),  or (B) an offset against  interest due under the Replacement
         Promissory  Note in an amount equal to the Second Credit Amount,  which
         offset  shall be taken  against  each  payment  of  accrued  and unpaid
         interest due thereunder until the Second Credit Amount shall be paid in
         full;  provided,  however,  that there  shall be no such  reduction  or
         offset if both the First Net Working Capital and the Second Net Working
         Capital exceed the threshold. APS shall have the right to select one of
         the  above-referenced  methodologies with respect to such Second Credit
         Amount,  which must be disclosed  in writing to Parent  within ten (10)
         business  days after such amount is agreed  upon or finally  determined
         under  subsection  (e) below.  If APS does not make a selection  within
         such ten (10) business day period,  Parent shall then have the right to
         select one of the  above-referenced  methodologies with respect to such
         Second Credit  Amount,  which must be disclosed in writing to APS on or
         before  the  date on which  next  interest  payment  is due  under  the
         Replacement  Promissory  Note. Any reduction or offset pursuant to this
         subsection  (d)(ii)  shall be  effective  contemporaneously  with  such
         determination.

                  (e) Net Working Capital Dispute Resolution. If, within 15 days
following  APS'  receipt of the First Net Working  Capital  Closing Date Balance
Sheet, APS shall not have objected in writing thereto, then the First Actual Net
Working  Capital shall be computed using such First Net Working  Capital Closing
Date Balance Sheet.  If, within 15 days following APS' receipt of the Second Net
Working  Capital  Closing Date  Balance  Sheet,  APS shall not have  objected in
writing  thereto,  then the Second Actual Net Working  Capital shall be computed
using such Second Net Working Capital Closing Date Balance Sheet. If APS objects
in writing to either  computation,  then APS and the Parent  shall  negotiate in
good faith and attempt to resolve their  disagreement.  Should such negotiations
not result in an agreement  within 20 days of Parent's receipt of the objection,
then the matter shall be submitted to a Neutral  Auditor.  If APS and Parent are
unable to agree on the Neutral  Auditor,  then APS and Parent shall  request the
American  Arbitration  Association to appoint the Neutral  Auditor.  The Neutral
Auditor  will  deliver  to  APS  and  Parent  a  written   determination   (such
determination  to include a worksheet  setting  forth all material  calculations
used in arriving at such  determination  and to be based  solely on  information
provided  to the  Neutral  Auditors  by APS  and  Parent,  or  their  respective
affiliates)  of the  disputed  items  within 30 days of receipt of the  disputed
items, which determination will be final, binding and conclusive on the parties.
If the Neutral Auditor's  determination of Net Working Capital is within $25,000
of Parent's  calculation of the Net Working  Capital  (whether the difference is
positive or  negative),  all fees and expenses  relating to  appointment  of the
Neutral  Auditor and the work,  if any, to be performed  by the Neutral  Auditor
will  be  borne  by  APS.  If  the  difference  between  the  Neutral  Auditor's
determination  of Net Working  Capital and Parent's  calculation  of Net Working
Capital is greater than $25,000, but less than or equal to $100,000 (whether the
difference  is  positive  or  negative),  all  fees  and  expenses  relating  to
appointment of the Neutral  Auditor and the work, if any, to be performed by the
Neutral Auditor will be borne half by APS and half by Parent.  If the difference
between the Neutral Auditor's  determination of Net Working Capital and Parent's
calculation  of the Net Working  Capital is greater than  $100,000  (whether the
difference  is  positive  or  negative),  all  fees  and  expenses  relating  to
appointment of the Neutral  Auditor and the work, if any, to be performed by the
Neutral Auditor will be borne exclusively by Parent.

                  (f)   Calculations Independent of Ownership. The  calculations
of Net Working  Capital in this Section 7.12 are made independent of the
ownership of the Surviving Corporation after Closing.

                  (g) No Other  Offsets.  Except as  expressly  provided in this
Section or in Section  7.13  below,  Parent and Merger Sub each agree that it is
not under any  circumstances  entitled to offset any amounts  owed under or with
respect to the Replacement Promissory Note.

         Section 7.13.  Advances under Promissory Note; Payables.

                  (a) First  Payables  Estimate.  Prior to the Closing Date, the
Company shall deliver to Parent a June 30, 1999 balance sheet of the Company, in
the form attached as Exhibit G hereto, setting forth an estimate of the accounts
payable and accrued  expenses of the Company in accordance  with GAAP (except as
adjusted on Exhibit F hereto) as of such date (the "First Payables Estimate").

                                       54

<PAGE>

If the  First  Payables  Estimate  is  greater  than  $200,000  (the  "Allowable
Amount"),  then APS shall, on the Closing Date, make an advance to the Surviving
Corporation  (the "First  Advance") under the Replacement  Promissory Note in an
amount equal to the  difference  between the First  Payables  Estimate minus the
Allowable  Amount.  The First Advance  shall have the effect on the  Replacement
Promissory Note as set forth in Section  7.12(a)  hereof.  APS shall deposit the
First Advance  directly  into a bank account  controlled by Parent (the "Deposit
Account"),  which shall be maintained  separately from other funds of the Parent
and shall be used  exclusively  for the payment of accounts  payable and accrued
expenses of the Surviving  Corporation  arising on or prior to June 30, 1999 and
determined  in  accordance  with GAAP  (except as adjusted on Exhibit F hereto).
Parent shall maintain such Deposit Account for a period of one (1) year from the
Closing Date, and shall provide APS copies of monthly  statements of the Deposit
Account and supporting invoices or other expense  documentation for all payments
over $5,000 during such period. If any balance remains outstanding at the end of
such one (1) year  period,  the amount in excess of accrued  vacation,  property
taxes, escheat liabilities and profit sharing amounts outstanding as of June 30,
1999 shall be returned to APS.

                  (b) Second Payables Estimate.  Immediately following agreement
upon or final  determination  of the  First Net  Working  Capital  Closing  Date
Balance Sheet pursuant to Section 7.12(c) and, if applicable,  Section  7.12(e),
Parent  and APS shall add the  accounts  payable  and  accrued  expenses  of the
Company set forth in the First Net Working  Capital  Closing Date Balance  Sheet
(the "Second Payables Estimate").

                           (i) If the Second Payables  Estimate is less than the
         First Payables  Estimate (such  difference  being referred to herein as
         the "Refund"),  Parent shall  distribute to APS cash in an amount equal
         to the  lesser of (A) the  Refund or (B) the First  Advance;  provided,
         however,  that there  shall be no such  payment  under  subsection  (i)
         hereof and subsection  (ii) below if both the First  Payables  Estimate
         and the Second  Payables  Estimate are less than the Allowable  Amount.
         The aggregate  distribution  pursuant to the preceding  sentence  shall
         decrease the principal  outstanding  under the  Replacement  Promissory
         Note, in an identical amount, as of the date the funds are paid to APS.

                           (ii) If the Second Payables  Estimate is greater than
         both the First  Payables  Estimate and the Allowable  Amount,  then APS
         shall  make an  advance  under  the  Replacement  Promissory  Note (the
         "Second Advance") to Surviving Corporation equal to the Second Payables
         Estimate  minus the  greater  of (A) the  Allowable  Amount and (B) the
         First Payables Estimate.  APS shall deposit the Second Advance directly
         into the  Deposit  Account.  The  Second  Advance  shall  increase  the
         principal  outstanding  under  the  Replacement  Promissory  Note in an
         identical  amount  as of the  date  the  funds  are  disbursed  by APS;
         provided,  however,  that if all or any portion of the Second  Advance,
         when  added  to  the   outstanding   principal  under  the  Replacement
         Promissory Note,  exceeds the Cap (such amount being referred to herein
         as the "Excess Advance"),  there shall be either (y) a reduction in the
         principal amount of the Replacement  Promissory Note by an amount equal
         to the Excess Advance, or (z) an offset against interest due under the

                                       55

<PAGE>

         Replacement  Promissory  Note in an amount equal to the Excess Advance,
         which offset shall be taken  against each payment of accrued and unpaid
         interest due thereunder until the Excess Advance shall be paid in full.
         APS  shall  have  the  right  to  select  one of  the  above-referenced
         methodologies  with  respect  to such  Excess  Advance,  which  must be
         disclosed in writing to Parent within ten (10) business days after such
         amount is agreed upon or finally determined as set forth herein. If APS
         does not make a  selection  within such ten (10)  business  day period,
         Parent shall then have the right to select one of the  above-referenced
         methodologies  with  respect  to such  Excess  Advance,  which  must be
         disclosed  in  writing  to APS on or  before  the  date on  which  next
         interest payment is due under the Replacement  Promissory Note.  Except
         for purposes of calculating Net Working Capital under Section 7.12, any
         reduction  or  offset  pursuant  to this  subsection  (b)(ii)  shall be
         effective contemporaneously with such determination.

         Section 7.14.  Advances under Promissory  Note;  Event of Default.  The
Company is guarantor of the following notes in connection with the merger of APA
Transition,  Inc.,  a Texas  corporation  ("APA"),  with and into the Company in
accordance with the terms of that certain Agreement and Plan of  Reorganization,
dated December 31, 1998, by and among the Company,  APA and David L. Berry, M.D.
(the "Berry Merger"): (i) Promissory Note, dated March 11, 1997, in the original
principal  amount of  $170,000,  by and between  Horizon  Bank & Trust,  SSB and
Austin  Perinatal  Associates,  P.A. (this Promissory Note was later acquired by
Compass  Bank);  (ii)  Promissory  Note,  dated March 20, 1998,  in the original
principal amount of $59,000,  by and between Norwest Bank Texas, N.A. and Austin
Perinatal  Associates,  P.A.; (iii) Fixed Rate Commercial Promissory Note, dated
February 27, 1998, in the original  principal amount of $20,000,  by and between
Compass Bank and Austin  Perinatal  Associates,  P.A.; and (iv) Promissory Note,
dated  November 6, 1998, in the original  principal  amount of $114,500,  by and
between  Norwest  Bank  Texas,  N.A.  and  Austin  Perinatal  Associates,   P.A.
(collectively,  the "Notes").  If, as a result of the Berry Merger,  an event of
default  occurs (or has already  occurred)  under the terms of any of the Notes,
and the  event of  default  results  in all or any  portion  of the  outstanding
principal plus unpaid interest and any other indebtedness under any of the Notes
(the "Default Amount") to be due and payable  immediately,  then APS shall, upon
the  earlier  of (i) the final  date  payment is  demanded  by the note  holder;
provided,  that the  Surviving  Corporation  shall use its good faith efforts to
extend the deadline for the demand for payment,  or (ii)  twenty-five  (25) days
after a  written  demand  for  payment  has been  made by the note  holder  (the
"Payment  Period"),  make an  advance  to the  Surviving  Corporation  under the
Replacement Promissory Note in an amount equal to the Default Amount;  provided,
however,  that the Surviving  Corporation shall use its commercially  reasonable
efforts  during the Payment Period to cure the event of default under any of the
Notes on equally favorable terms to the Surviving  Corporation.  For purposes of
this Section 7.14 only, the principal amount of the Replacement  Promissory Note
(including the Default Amount) may exceed the Cap; provided,  however,  that the
principal  amount of the Replacement  Promissory Note that exceeds the Cap shall
be excluded  from the Net Working  Capital  calculation  for purposes of Section
7.12 of this Agreement.

         Section 7.15.  Non-Interference.

                                       56

<PAGE>

                  (a) At all times during the Determination Period, Parent shall
use its commercially reasonable efforts to ensure that (i) Parent and Merger Sub
(or other FemPartners'  subsidiary) operate the Company Existing Practices under
the terms of the Existing Management Agreements,  (ii) neither Parent nor Merger
Sub (or other  FemPartners'  subsidiary)  take (or fail to take) any action,  if
such  action or  omission  is done with the  primary  intent  of  causing  (A) a
decrease in the amount of Retained Shares that would otherwise be distributed to
the  Shareholders on the  Distribution  Date or (B) a decrease in the balance of
the  Replacement  Promissory  Note  pursuant to the operation of Section 7.12 or
Section 7.13, and (iii) neither Parent nor Merger Sub (or any other FemPartners'
subsidiary) take (or fail to take) any action, if such action or omission causes
Parent  or  Merger  Sub to be in  material  breach  of the  Existing  Management
Agreements.  Notwithstanding  anything in this Section 7.15 to the contrary,  in
the event  Parent or Merger Sub take (or fail to take) any action  because  such
action or omission is (i) required pursuant to any statute,  rule, regulation or
other legal requirement or (ii) approved by the Joint Planning Board pursuant to
the  terms  of the  Existing  Management  Agreement  of any  Existing  Practice,
including, without limitation,  approval of the budget of any Existing Practice,
then neither  Parent nor Merger Sub will be in breach of any Existing  Agreement
or this  Agreement  (regardless  of whether  such  action or  inaction  causes a
decrease in the number of Retained Shares that would otherwise be distributed to
the  Shareholders on the  Distribution  Date or a decrease in the balance of the
Replacement Promissory Note pursuant to the operation of Section 7.12 or Section
7.13).

                  (b)  Parent  and  Merger Sub each agree that if either of them
materially  violates any provision of this  Agreement  during the  Determination
Period,  or changes the terms of the Existing  Management  Agreements during the
Determination  Period,  and such  violation  or change has the direct  effect of
reducing the number of Retained  Shares that would  otherwise be  distributed to
the Shareholders on the Distribution Date or decreasing the amount payable under
the  Replacement  Promissory  Note  pursuant to the operation of Section 7.12 or
Section 7.13, then the Adjustment  Calculations and the amounts calculated under
Section  7.12 and Section 7.13 shall be  calculated  as if such breach or change
had not occurred.

                  (c)  Parent and Merger  Sub  acknowledge  that  certain of the
physicians in the Company  Existing  Practices owe the Company money because the
Company has advanced sums under the respective Existing Management Agreements in
excess of the difference  between the monthly  Practice Accrual Earnings and the
Service Fee (as defined in the respective  Existing  Management  Agreements) (as
reflected on the  Company's  books as of June 30,  1999,  and in the Side Letter
Agreements relating to the excess payments executed by certain  physicians,  the
"Advances").  Parent,  Merger Sub and the  Company  each  acknowledge  that each
Advance may be increased,  after the Closing, in order to correct any inaccurate
estimates  of  Adjustments  (as defined in the  respective  Existing  Management
Agreement)  with respect to accounts  receivable  existing on June 30, 1999 (the
amount of such increase, if any, the "Excess Advances").  Solely for purposes of
construing  Parent's and Merger Sub's  obligations  under this Section  7.15, if
Parent or Merger Sub (or any other FemPartners'  subsidiary) fails or refuses to
collect  that  portion of the  Excess  Advances  which  exceed the lesser of (i)
$12,000 (per physician) or (ii) ten percent (10%) of the net book value of the

                                       57

<PAGE>

accounts  receivable of the respective  Company Existing Practice as of June 30,
1999, then, except for the practices of M.R. Jafarnia, M.D. & Associates, Donald
Columbus,  M.D., P.A. and Lawrence M. Slocki,  M.D., P.A. (which are governed by
the Side  Letter  Agreements  between the  Company  and such  physicians),  such
failure or refusal will not be  considered  a material  breach of, or change to,
the respective Existing Management  Agreements or this Agreement  (regardless of
whether  such  action or  inaction  causes a decrease  in the number of Retained
Shares  that  would  otherwise  be  distributed  to  the   Shareholders  on  the
Distribution  Date or a decrease  in the balance of the  Replacement  Promissory
Note pursuant to the operation of Section 7.12 or 7.13). Subject to the terms of
the Existing  Management  Agreements and the applicable  Side Letter  Agreements
entered  into with the  physicians  with  respect  to the  Advances  and  Excess
Advances,  Parent and  Merger  Sub agree that they shall use their  commercially
reasonable efforts (as though Parent and Merger Sub were not affiliated with the
physicians)  to collect  (y) the total  amount of each  Advance  (subject to any
decrease,  after  the  Closing,  based  solely on  higher-than-estimated  actual
collections of accounts receivable existing on June 30, 1999), and (z) the total
amount  of any  Excess  Advance  subject  to the  limitations  above;  provided,
however, that Parent and Merger Sub shall not be required to collect any amounts
that Lawrence M. Slocki,  M.D. would have received from Medicaid  billings,  but
that are no longer  collectible  solely  because of the delay by the  Company in
billing  such  Medicaid  amounts.  Any  failure to use  commercially  reasonable
efforts  (as  though  Parent  and  Merger  Sub  were  not  affiliated  with  the
physicians)  to collect  the  amounts  described  in the  immediately  preceding
sentence  will be  considered  a breach  solely for the  purposes of  construing
Parent's and Merger Sub's obligations under this Section 7.15.

         Section 7.16. Insurance. Parent and Merger Sub agree to maintain at all
times  after the  Closing  Date and until July 1, 2001,  a prior acts  insurance
policy providing  insurance  coverage of the same scope, in the same amounts and
subject to the same deductibles as the Company's insurance in effect immediately
prior to the Closing Date.

                              CONDITIONS TO CLOSING

                  (s) Parent shall have received a certificate, dated within ten
(10)  days  of  the  Closing  Date,  of the  Secretary  of the  State  of  Texas
establishing  that  the  Company  is in  existence  and is in good  standing  to
transact business in the state of incorporation;

                  (t)      Parent shall have received the resignations of the
directors and officers of the Company; and

                  (u) Parent  shall  have  received a  certificate  executed  on
behalf of the Company by the President or Chief Executive Officer of the Company
and each of the Shareholders with respect to (a) through (i) above.

                  (a)      The Company shall have the right to terminate this
Agreement:

                           (i) if the  representations  and warranties of Parent
         and  Merger  Sub  shall  fail to be true and  correct  in all  material

                                       62

         respects  (or in all  respects  in the  case of any  representation  or
         warranty  containing any  materiality  qualification)  on and as of the
         date  made  or,  except  in the case of any  such  representations  and
         warranties  made as of a specified  date,  on and as of any  subsequent
         date as if made at and as of subsequent date and such failure shall not
         have been cured in all  material  respects  (or in all  respects in the
         case of any  representation  or  warranty  containing  any  materiality
         qualification)  within 30 days after written  notice of such failure is
         given to Parent by the Company;

                           (ii) if the  Merger is not  completed  by August  31,
         1999 (provided  that the right to terminate  this Agreement  under this
         Section 9.1(a)(ii) shall not be available to the Company if the failure
         of the  Company  to  fulfill  any  obligation  to  Parent  under  or in
         connection with this Agreement has been the cause of or resulted in the
         failure of the Merger to occur on or before such date);

                           (iii)    if the Merger is enjoined by a final,
unappealable court order; or

                           (iv) if Parent or Merger  Sub (A) fails to perform in
         any material  respect any of its  covenants  (or in all respects in the
         case of any covenant containing any materiality  qualification) in this
         Agreement  and (B) does not cure such default in all material  respects
         (or in all  respects  in  the  case  of  any  covenant  containing  any
         materiality  qualification) within 30 days after notice of such default
         is given to Parent by the Company.

                  (b)   Parent shall have the right to terminate this Agreement;

                           (i)  if the  representations  and  warranties  of the
         Company shall fail to be true and correct in all material  respects (or
         in  all  respects  in  the  case  of  any  representation  or  warranty
         containing any  materiality  qualification)  on and as of the date made
         or, except in the case of any such  representations and warranties made
         as of a specified  date, on and as of any subsequent date as if made at
         and as of such  subsequent  date and such  failure  shall not have been
         cured in all  material  respects (or in all respects in the case of any
         representation  or warranty  containing any materiality  qualification)
         within 30 days  after  written  notice of such  failure is given to the
         Company by Parent;

                           (ii) if the  Merger is not  completed  by August  31,
         1999 (provided  that the right to terminate  this Agreement  under this
         Section  9.1(b)(ii)  shall not be available to Parent if the failure of
         Parent to fulfill any  obligation to the Company under or in connection
         with this Agreement has been the cause of or resulted in the failure of
         the Merger to occur on or before such date);

                           (iii)    if the Merger is enjoined by a final,
unappealable court order; or

                           (iv) if the  Company  (A)  fails  to  perform  in any
         material  respect  (or in all  respects  in the  case  of any  covenant
         containing any materiality  qualification) any of its covenants in this
         Agreement and (B) does not cure such default in all material respects

                                       63

<PAGE>

         (or in all  respects  in  the  case  of  any  covenant  containing  any
         materiality  qualification) within 30 days after notice of such default
         is given to the Company by Parent.

                  (c)      The Company and Parent mutually agree.

         Section 9.2. Effect of Termination. In the event of termination of this
Agreement by either Parent or the Company  pursuant to the provisions of Section
9.1, this Agreement  shall  forthwith  become void and there shall be no further
obligations on the part of the Company,  Parent,  Merger Sub or their respective
officers or directors  (except as set forth in Sections  11.5 and 11.6,  each of
which  shall  survive  termination);  provided,  however,  that  nothing in this
Section 9.2 shall  relieve  either party from  liability  for any breach of this
Agreement.

         Section 9.3.  Amendment.  This  Agreement may not be amended  except by
an  instrument  in writing  signed on behalf of all of the parties.

         Section 9.4.  Extensions;  Waiver.  At any time prior to the  Effective
Time, the parties  hereto may (a) extend the time for the  performance of any of
the  obligations  or other  acts of the  other  parties  hereto,  (b)  waive any
inaccuracies in the  representations  and warranties  contained herein or in any
document  delivered  pursuant  thereto and (c) waive  compliance with any of the
agreements or conditions  herein. Any agreement on the part of a party hereto to
any such  extension  or waiver shall be valid if set forth in an  instrument  in
writing signed on behalf of such party.

                                 INDEMNIFICATION

         Section 10.1. The Shareholders' Indemnity Obligations. The Shareholders
shall,  severally  and not  jointly,  indemnify  and hold  harmless the Company,
Parent  and  the  Company's  and  Parent's   respective   officers,   directors,
stockholders,  employees, agents, representatives and Affiliates (each a "Parent
Indemnified  Party")  from and  against  any and all claims  (including  without
limitation,  Environmental  Claims malpractice  claims,  escheat laws and claims
pursuant to Sections 5.28 and 5.29),  actions,  causes of action,  arbitrations,
proceedings,  losses, damages,  remediations,  liabilities,  strict liabilities,
judgments,  fines,  penalties  and  expenses  (including,   without  limitation,
reasonable  attorneys' fees)  (collectively,  the  "Indemnified  Amounts") paid,
imposed on or incurred by a Parent  Indemnified  Party,  directly or indirectly,
relating  to,  resulting  from or arising out of, or any  allegation  of a third
party of (a) any breach or  misrepresentation  in any of the representations and
warranties made by the Company in this Agreement,  including without  limitation
with  respect  to  environmental  matters,  or  any  certificate  or  instrument
delivered in connection with this Agreement,  (b) any violation or breach by the
Company of or default by the Company  under the terms of this  Agreement  or any
certificate or instrument  delivered in connection with this Agreement,  (c) any
act or omission by the Company or any shareholder,  officer, director, employee,
agent or  representative  of the  Company,  occurring on or prior to the Closing
Date (including any claim by a third party,  including  employees and customers,
arising  out  of or  related  to any  act or  omission  by  the  Company  or any
shareholder, officer, director, employee, agent or representative of the Company

                                       64

occurring on or prior to the Closing Date) or (d) any Environmental Claim and/or
any violation of any Environmental Law if such Environmental  Claim or violation
relates, directly or indirectly,  to events,  conditions,  operations,  facts or
circumstances  which  occurred or commenced on or prior to the Closing Date. The
obligation of Shareholders to provide  indemnification  to a Parent  Indemnified
Party  hereunder  based on a breach of  representation  or warranty  shall arise
without  regard to any  materiality  or  knowledge  qualifier  set forth in such
representation or warranty, except for any claim based on fraud. For purposes of
this Section 10.1,  Indemnified  Amounts shall include without  limitation those
Indemnified  Amounts  ARISING  OUT OF THE STRICT  LIABILITY  (INCLUDING  BUT NOT
LIMITED  TO  STRICT  LIABILITY  ARISING  PURSUANT  TO  ENVIRONMENTAL   LAWS)  OR
NEGLIGENCE OF ANY PARTY,  INCLUDING ANY PARENT INDEMNIFIED  PARTY,  WHETHER SUCH
NEGLIGENCE BE SOLE, JOINT OR CONCURRENT, ACTIVE OR PASSIVE.

         Section 10.2.  Parent's  Indemnity  Obligations.  Parent and Merger Sub
shall indemnify and hold harmless the Shareholders and the Shareholders' agents,
representatives  and Affiliates (each a "Shareholders'  Indemnified Party") from
and  against  any  and  all  Indemnified  Amounts  incurred  by a  Shareholders'
Indemnified Party as a result of (a) any breach or  misrepresentation  in any of
the  representations and warranties made by or on behalf of Parent or Merger Sub
in this Agreement or any certificate or instrument  delivered in connection with
this  Agreement,  (b) any  violation  or breach  by  Parent or Merger  Sub of or
default  by Parent  under  the terms of this  Agreement  or any  certificate  or
instrument delivered in connection with this Agreement,  (c) any act or omission
by the Parent or any Parent Indemnified Party,  occurring after the Closing Date
(including  any  claim by a third  party,  including  employees  and  customers,
arising  out of or  related to any act or  omission  by the Parent or any Parent
Indemnified  Party  occurring  after the Closing Date) or (d) any  Environmental
Claim and/or any violation of any Environmental Law if such Environmental  Claim
or violation relates, directly or indirectly, to events, conditions, operations,
facts or  circumstances  which occurred or commenced after the Closing Date. The
obligation of Parent to provide  indemnification to a Shareholders'  Indemnified
Party  hereunder  based on a breach of  representation  or warranty  shall arise
without  regard to any  materiality  or  knowledge  qualifier  set forth in such
representation or warranty, except for any claim based on fraud. For purposes of
this Section 10.2,  Indemnified  Amounts shall include without  limitation those
Indemnified  Amounts  ARISING  OUT OF THE STRICT  LIABILITY  (INCLUDING  BUT NOT
LIMITED  TO  STRICT  LIABILITY  ARISING  PURSUANT  TO  ENVIRONMENTAL   LAWS)  OR
NEGLIGENCE OF ANY PARTY, INCLUDING ANY SHAREHOLDERS'  INDEMNIFIED PARTY, WHETHER
SUCH NEGLIGENCE BE SOLE, JOINT OR CONCURRENT, ACTIVE OR PASSIVE. Notwithstanding
the foregoing, neither Parent nor Merger Sub shall indemnify the Shareholders or
Shareholders'  Indemnified  Parties under  subsections  (c) or (d) above for any
reduction in the value of the Parent Common Stock issued as Merger Consideration
pursuant to this Agreement based on an event or circumstance  which occurs after
the Closing Date.

         Section  10.3.  Indemnification  Procedures.  All claims  for
indemnification under this Agreement shall be asserted  and resolved as follows:

                                       65

<PAGE>

                  (a) A party claiming  indemnification under this Agreement (an
"Indemnified Party") shall with reasonable  promptness (i) notify the party from
whom  indemnification  is sought (the  "Indemnifying  Party") of any third-party
claim or claims asserted against the Indemnified Party ("Third Party Claim") for
which  indemnification  is sought and (ii) transmit to the Indemnifying  Party a
copy of all  papers  served  with  respect  to such claim (if any) and a written
notice ("Claim  Notice")  containing a description  in reasonable  detail of the
nature  of the  Third  Party  Claim,  an  estimate  of  the  amount  of  damages
attributable  to the Third Party Claim to the extent  feasible  (which  estimate
shall not be  conclusive of the final amount of such claim) and the basis of the
Indemnified Party's request for indemnification under this Agreement.

         Within  15 days  after  receipt  of any  Claim  Notice  (the  "Election
Period"),  the Indemnifying Party shall notify the Indemnified Party (i) whether
the Indemnifying Party disputes its potential liability to the Indemnified Party
with respect to such Third Party Claim and (ii) whether the  Indemnifying  Party
desires,  at the sole cost and expense of the Indemnifying  Party, to defend the
Indemnified Party against such Third Party Claim.

         If the  Indemnifying  Party notifies the  Indemnified  Party within the
Election Period that the Indemnifying  Party elects to assume the defense of the
Third Party Claim,  then the Indemnifying  Party shall have the right to defend,
at its  sole  cost and  expense,  such  Third  Party  Claim  by all  appropriate
proceedings,   which   proceedings   shall  be  prosecuted   diligently  by  the
Indemnifying  Party to a final  conclusion  or settled at the  discretion of the
Indemnifying  Party in accordance with this Section  10.3(a).  The  Indemnifying
Party shall have full control of such

                                       66

<PAGE>

defense and  proceedings.  The Indemnified

Party is hereby  authorized,  at the sole cost and  expense of the  Indemnifying
Party,  to file,  during  the  Election  Period,  any  motion,  answer  or other
pleadings  that  the  Indemnified  Party  shall  reasonably  deem  necessary  or
appropriate to protect its interests.  If requested by the  Indemnifying  Party,
the Indemnified Party reasonably agrees to cooperate with the Indemnifying Party
and its counsel in contesting any Third Party Claim that the Indemnifying  Party
elects to  contest,  including,  without  limitation,  the making of any related
counterclaim  against  the  person  asserting  the  Third  Party  Claim  or  any
cross-complaint  against any person.  Except as otherwise  provided herein,  the
Indemnified Party may participate in, but not control, any defense or settlement
of any Third Party claim controlled by the  Indemnifying  Party pursuant to this
Section  10.3 and shall  bear its own costs and  expenses  with  respect to such
participation.

         If the Indemnifying  Party fails to notify the Indemnified Party within
the Election Period that the Indemnifying Party elects to defend the Indemnified
Party pursuant to the preceding  paragraph,  or if the Indemnifying Party elects
to defend the Indemnified Party but fails to prosecute or settle the Third Party
Claim as herein provided or if the Indemnified Party reasonably  objects to such
election on the grounds that counsel for such Indemnified Party cannot represent
both  the  Indemnified   Party  and  the   Indemnifying   Parties  because  such
representation  would be reasonably  likely to result in a conflict of interest,
then the Indemnified  Party shall have the right to defend, at the sole cost and
expense of the  Indemnifying  Party,  the Third Party  Claim by all  appropriate
proceedings,  which proceedings  shall be promptly and vigorously  prosecuted by
the Indemnified Party to a final conclusion or settled. In such a situation, the
Indemnified  Party shall have full control of such defense and  proceedings  and
the  Indemnifying  Party may  participate  in, but not  control,  any defense or
settlement  controlled by the  Indemnified  Party pursuant to this Section 10.3,
and the Indemnifying Party shall bear its own costs and expenses with respect to
such participation.

         The  Indemnifying  Party shall not settle or compromise any Third Party
Claim unless (i) the terms of such compromise or settlement require no more than
the payment of money (i.e.,  such  compromise or settlement does not require the
Indemnified  Party to admit any  wrongdoing  or take or refrain  from taking any
action),  (ii) the full amount of such monetary compromise or settlement will be
paid by the Indemnifying Party, and (iii) the Indemnified Party receives as part
of such settlement a legal, binding and enforceable  unconditional  satisfaction
and/or release, in form and substance  reasonably  satisfactory to it, providing
that such Third Party Claim and any claimed  lability of the  Indemnified  Party
with respect  thereto is being fully  satisfied by reason of such  compromise or
settlement  and that the  Indemnified  Party is being  released from any and all
obligations  or liabilities it may have with respect  thereto.  The  Indemnified
Party shall not settle or admit  liability to any Third Party Claim  without the
prior  written  consent of the  Indemnifying  Party unless (x) the  Indemnifying
Party has disputed its potential  liability to the Indemnified  Party,  and such
dispute  either  has not  been  resolved  or has been  resolved  in favor of the
Indemnifying  Party or (y) the  Indemnifying  Party has failed to respond to the
Indemnified Party's Claim Notice.

                  (b) In the event any  Indemnified  Party  should  have a claim
against any  Indemnifying  Party  hereunder  that does not involve a Third Party
Claim, the Indemnified Party shall transmit to the Indemnifying  Party a written
notice (the "Indemnity  Notice")  describing in reasonable  detail the nature of
the claim,  an estimate of the amount of damages  attributable  to such claim to
the extent  feasible (which estimate shall not be conclusive of the final amount
of  such  claim)  and  the  basis  of  the   Indemnified   Party's  request  for
indemnification under this Agreement.

         Section 10.4.  Determination and Payment of Indemnified Amounts.

                  (a)  Determination  of  Indemnified  Amounts.  Subject  to the
limitations  on Indemnified  Amounts set forth in Section 10.7, the  Indemnified
Amounts  payable by an  Indemnifying  Party hereunder shall be determined (i) by
binding arbitration pursuant to Section 11.6 hereof or (ii) if no party requests
such  arbitration,  then  by (A)  the  written  agreement  of the  parties,  (B)
mediation,  (C) final judgment or decree of any court of competent jurisdiction,
or (D) by any other  means  agreed to in writing by the  parties.  A judgment or
decree of a court shall be deemed final when the time for appeal,  if any, shall
have expired and no appeal shall have been taken or when all appeals  taken have
been fully determined.

                  (b)  Payment  of  Indemnified  Amounts.  For  the  purpose  of
satisfying any Indemnified Amounts under this Article X, the Parent Common Stock
shall be conclusively valued at a per share price of $7.00 per share. Subject in
all cases to the  limitations  on liability set forth in Sections 10.5 and 10.6,
the Indemnifying Party shall pay to the Indemnified Party the Indemnified Amount
to which the Indemnified  Party may become entitled by reason of this Agreement,
payable in the following manner:

                                       67

<PAGE>

                           (i)  Indemnified  Amounts  Payable by Parent.  Parent
         may,  in its sole  discretion,  pay an  Indemnified  Amount by  issuing
         additional shares of Parent Common Stock or by making a cash payment to
         the Shareholders'  Indemnified Parties,  such payment to be made within
         fifteen (15) days after such Indemnified  Amount is finally  determined
         pursuant to this Section 10.4.

                           (ii) Indemnified  Amounts Payable by the Shareholders
         Prior to the  Distribution  Date.  With respect to the aggregate of all
         Indemnified  Amounts owed by the Shareholders that are determined prior
         to the  Distribution  Date,  Shareholders  shall (subject to subsection
         (iv) below)  fully  satisfy  such  Indemnified  Amounts by  immediately
         forfeiting their right to receive on the Distribution  Date that number
         of Retained  Indemnity  Shares which fully  satisfies such  Indemnified
         Amount; provided,  however, that the Shareholders shall not be required
         to  satisfy  or  pay  prior  to  the  Distribution  Date  such  finally
         determined  Indemnified  Amounts to the extent that such amounts exceed
         the value of the Retained Indemnity Shares;  provided further, that any
         portion of such finally  determined  Indemnified  Amounts which exceeds
         the  value of the  Retained  Indemnity  Shares  (the  "Final  Suspended
         Indemnified   Amounts")  shall  be  held  in  abeyance   pending  final
         calculation  of the  Earnout  Distribution  on the  Distribution  Date.
         Subject to subsection (iv), on the Distribution  Date, the Shareholders
         shall satisfy any Final Suspended Indemnified Amounts by forfeiting the
         right to receive  all or any portion of shares of Parent  Common  Stock
         constituting the Earnout Distribution as provided in Section 3.2.

                           (iii)   Indemnified   Amounts   Asserted   by  Parent
         Indemnified  Parties Prior to the  Distribution  Date,  but Not Finally
         Determined  Prior  to  the  Distribution  Date.  With  respect  to  the
         aggregate  of all  Indemnified  Amounts  first  asserted  prior  to the
         Distribution Date, but that are not finally determined on or before the
         Distribution  Date (the "Pending  Indemnified  Amounts"),  a sufficient
         number of shares of Parent Common Stock, otherwise distributable to the
         Shareholders on the Distribution  Date (including the Retained Shares),
         shall not be distributed to the  Shareholders but shall instead be held
         by Parent in escrow pending (and shall be distributed  only upon) final
         determination  of such  Pending  Indemnified  Amounts.  Shares  held by
         Parent  in  escrow  after  the  Distribution   Date  pursuant  to  this
         subsection  (iii) shall first be comprised  of any  Retained  Indemnity
         Shares not  forfeited  pursuant  to  subsection  (ii) above and next be
         comprised of any shares of Parent Common Stock constituting the Earnout
         Distribution,  if any, that were not  forfeited  pursuant to subsection
         (ii) above.

                           (iv)   Indemnified    Amounts   Payable   to   Parent
         Indemnified Parties Which Cannot be Satisfied by the Retained Indemnity
         Shares and the Shares of Parent Common Stock  Constituting  the Earnout
         Distribution.  With respect to the aggregate of all Indemnified Amounts
         payable to Parent  Indemnified  Parties  which (A) exceed the  Retained
         Indemnity Shares and the shares of Parent Common Stock constituting the
         Earnout  Distribution  and/or (B) are  asserted  after such shares have
         been distributed to the Shareholders, APS shall,

                                       68

<PAGE>

         subject  to APS'
         limitation  on  liability   set  forth  in  Section  10.5,   solely  be
         responsible  for paying 64% of such  Indemnified  Amounts  when finally
         determined (except for Indemnified Amounts exclusively arising directly
         out of a breach or misrepresentation under Sections 5.2 and 5.4 of this
         Agreement, which shall be 100% of such Indemnified Amounts when finally
         determined).  In the event that APS no longer owns a sufficient  number
         of  shares  of  Parent  Common  Stock  to  fully  satisfy  its  maximum
         obligation  under this subsection  (iv), then (and only then) shall APS
         be required to pay cash to satisfy such Indemnified  Amounts (up to its
         maximum  liability  provided in Section 10.5 and as further  limited in
         this subsection (iv)).

         Section 10.5.  Limitation of Shareholders' Liability.

                  (a)  Notwithstanding  anything to the  contrary  contained  in
Article X, the aggregate  liability of each Shareholder (other than APS) for any
event  or  occurrence  giving  rise to an  Indemnified  Amount  payable  by that
Shareholder   under  Section  10.1  shall  be  limited  to  that   Shareholders'
proportionate  share of the  Retained  Shares  plus any  other  shares of Parent
Common Stock constituting the Earnout Distribution, multiplied by $7, payable as
set forth in Section 10.4. The shares of Parent Common Stock  transferred to the
Parent  Indemnified  Parties  hereunder  shall be free and  clear of all  liens,
claims, options, pledges, encumbrances, restrictions and adverse interest of any
kind or nature  whatsoever.  The  Shareholders  shall  each  have the  option of
satisfying their respective  indemnification  obligations  under Section 10.1 by
using cash instead of Parent Common Stock.

                  (b)  Notwithstanding  anything to the  contrary  contained  in
Article X, the  aggregate  liability of APS for any event or  occurrence  giving
rise to an Indemnified Amount payable by APS under Section 10.1 shall be limited
to the  number of shares of  Parent  Common  Stock  issued to APS as part of the
Merger  Consideration,  multiplied by $7,  payable as set forth in Section 10.4.
The shares of Parent Common Stock transferred to the Parent Indemnified  Parties
hereunder  shall  be free and  clear of all  liens,  claims,  options,  pledges,
encumbrances,   restrictions   and  adverse  interest  of  any  kind  or  nature
whatsoever.  In accordance with Section 10.4(b)(iv) APS shall have the option of
satisfying  its  respective  indemnification  obligations  under Section 10.1 by
using cash  instead of Parent  Common  Stock.  Notwithstanding  anything  to the
contrary  contained  in  Article  X, APS  shall  never be  required  to pay cash
pursuant to this  Article X, except in instances  where,  and only to the extent
that (i) APS is  obligated  to pay an  Indemnified  Amount  under this Article X
after the  Distribution  Date, (ii) the aggregate  amount of APS' prior payments
under  this  Article  X is less  than the  maximum  aggregate  liability  of APS
determined  pursuant to the first sentence of this subsection (b), (iii) APS has
sold,  transferred or otherwise  disposed of any of its Parent Common Stock, and
(iv) as a result of such  disposition(s),  APS does not have a sufficient number
of shares of Parent Common Stock to satisfy such Indemnified Amount.

                  (c) Parent Indemnified Parties are entitled to indemnification
pursuant to Section  10.1 only to the extent that the amount of any  Indemnified
Amount, individually or in the aggregate, exceeds $100,000, and then to the full
amount of such Indemnified Amount, including the first $100,000.

         Section 10.6.  Limitation of Parent's Liability.

                  (a)  Notwithstanding  anything to the  contrary  contained  in
Article X, the aggregate  liability of Parent for any event or occurrence giving
rise to an  Indemnified  Amount  payable by Parent  under  Section 10.2 shall be
limited to the number of shares of parent  Common Stock issued to APS as part of
the  Merger  Consideration,  multiplied  by $7,  payable as set forth in Section
10.4.

                  (b)   Company    Indemnified    Parties   are    entitled   to
indemnification  pursuant to Section  10.2 only to the extent that the amount of
any Indemnified Amount,  individually or in the aggregate,  exceeds $100,000 and
then to the  full  amount  of  such  Indemnified  Amount,  including  the  first
$100,000.

         Section 10.7.  Limitation on Indemnified  Amounts.  Notwithstanding any
provision  of this  Article X to the  contrary,  Indemnified  Amounts owed by an
Indemnifying Party to an Indemnified Party shall be reduced by the amount of any
mitigating  recovery or benefit  (net of  reasonable  expenses and tax and other
costs incurred in obtaining such recovery or benefit) an Indemnified Party shall
have received or otherwise  enjoyed with respect thereto from any recovery under
any  insurance  policies,  without  regard to whether the  Indemnified  Party or
another  person paid the premiums  therefor.  If such a  mitigating  recovery is
received by an Indemnified  Party after it receives payment under this Agreement
with respect to Indemnified Amounts,  then a refund equal in aggregate amount to
the  mitigating  recovery,  net of  reasonable  expenses  and tax or other costs
incurred in  obtaining  recovery,  shall be made  promptly  to the  Indemnifying
Party.  Notwithstanding  the foregoing or any other provision of this Agreement,
no Parent Indemnified Person shall be entitled to indemnification hereunder with
respect to an indemnifiable claim to the extent such claim directly causes (i) a
reduction  to the  principal  amount of the  Replacement  Promissory  Note or an
offset against interest  otherwise due and payable thereunder as a result of the
operation of Section 7.12 of this Agreement,  or (ii) a reduction in the Earnout
Distribution pursuant to Section 3.2 of this Agreement.

         Section 10.8.  Right of  Subrogation.  Upon payment by an  Indemnifying
Party of an Indemnified  Amount,  the Indemnifying  Party shall, with respect to
the amount  paid,  be  subrogated  to all causes of action,  rights of  recovery
and/or  enforcement  rights  that  the  Indemnified  Party  may have  under  any
contract, agreement,  instrument or understanding (other than this Agreement and
the  other  agreements  entered  into  in  connection   herewith)  to  which  an
Indemnified Party is a party or otherwise receives benefits.

                                       72

<PAGE>

                  (a) General.  Notwithstanding  any provision of this Agreement
to the contrary,  upon the request of any party (defined for the purpose of this
provision to include  affiliates,  principles and agents of any such party), any
dispute,  controversy  or claim (under any theory of law,  equity or  otherwise,
except  only for claims  exclusively  for  injunctive  relief)  arising  out of,
relating to, or in connection with, this Agreement or any agreement  executed in
connection  herewith  or  contemplated  hereby,  or  the  breach,   termination,
interpretation,  or  validity  hereof or thereof  (hereinafter  referred to as a
"Dispute"),  shall be finally  resolved by mandatory and binding  arbitration in
accordance with the terms hereof;  provided,  however, that any dispute relating
to the  non-payment  of the  Replacement  Promissory  Note or the  provisions of
Section  3.2 or the  provisions  of  Section  7.12  shall not be  subject to the
provisions of this Section.  Any party to this  Agreement may bring an action in
court to compel  arbitration  of any Dispute.  Any party who fails or refuses to
submit any  Dispute  to binding  arbitration  following  a lawful  demand by the
opposing party shall bear all costs and expenses  incurred by the opposing party
in compelling arbitration of such Dispute.

                  (b) Governing  Rules.  The  arbitration  shall be conducted in
accordance  with the Commercial  Arbitration  Rules of the American  Arbitration
Association  in  effect  at the time of the  arbitration,  except as they may be
modified  herein  or by  mutual  agreement  of  the  parties.  The  seat  of the
arbitration  shall  be  Dallas,   Texas.   Notwithstanding   Section  11.5,  the
arbitration and this clause shall be governed by the Federal  Arbitration Act, 9
U.S.C.  ss.ss. 1 et seq. (the "Federal  Arbitration  Act"). The arbitrator shall
award all reasonable  and necessary  costs  (including  the reasonable  fees and
expenses of counsel)  incurred in conducting  the  arbitration to the prevailing
party in any such Dispute.  The parties expressly waive all rights whatsoever to
file an appeal  against or otherwise to challenge  any award by the  arbitrators
hereunder;  provided,  that the  foregoing  shall not limit the rights of either
party to bring a proceeding in any applicable  jurisdiction to confirm,  enforce
or enter  judgment  upon such award (and the rights of the other party,  if such
proceeding  is brought to contest  such  confirmation,  enforcement  or entry of
judgment, but only to the extent permitted by the Federal Arbitration Act).

                  (c) No Waiver;  Preservation of Remedies. No provision of, nor
the  exercise of any rights  under this  Agreement  shall limit the right of any
party to apply for injunctive relief or similar equitable relief with respect to
the  enforcement  of this  Agreement  or any  agreement  executed in  connection
herewith or  contemplated  hereby,  and any such  action  shall not be deemed an
election of  remedies.  Such rights can be  exercised  at any time except to the
extent such  action is contrary to a final award or decision in any  arbitration
proceeding.  The institution and maintenance of an action for injunctive  relief
or similar  equitable  relief shall not  constitute a waiver of the right of any
party,  including  without  limitation the  plaintiff,  to submit any Dispute to
arbitration nor render  inapplicable  the compulsory  arbitration  provisions of
this Agreement.

                  (d)  Arbitration  Proceeding.  In  addition  to the  authority
conferred  on  the  arbitration  tribunal  by the  rules  specified  above,  the
arbitration  tribunal  shall have the authority to order  reasonable  discovery,
including the  deposition of party  witnesses and  production of documents.  The
arbitral  award  shall be in writing,  state the  reasons for the award,  and be
final and  binding  on the  parties.  All  statutes  of  limitations  that would
otherwise be applicable shall apply to

                                       73

<PAGE>

any  arbitration  proceeding.   Any
attorney-client   privilege   and  other   protection   against   disclosure  of
confidential  information,  including without limitation any protection afforded
the  work-product of any attorney,  that could otherwise be claimed by any party
shall be  available  to and may be claimed by any such party in any  arbitration
proceeding.   No  party  waives  any  attorney-client  privilege  or  any  other
protection against disclosure of confidential  information by reason of anything
contained in or done  pursuant to or in  connection  with this  Agreement.  Each
party  agrees  to  keep  all  Disputes  and  arbitration   proceedings  strictly
confidential,  except for  disclosures  of  information  to the  parties'  legal
counsel or auditors or those required by applicable law. The  arbitrators  shall
determine  the  matters in dispute in  accordance  with the  substantive  law of
Texas, without regard to conflict of law rules.

                  (e)  Appointment  of  Arbitrators.  The  arbitration  shall be
conducted  by three (3)  arbitrators.  The  party  initiating  arbitration  (the
"Claimant")  shall appoint its  arbitrator in its request for  arbitration  (the
"Request").  The other party (the  "Respondent")  shall  appoint its  arbitrator
within  thirty  (30) days after  receipt  of the  Request  and shall  notify the
Claimant of such  appointment in writing.  If the Respondent fails to appoint an
arbitrator  within  such thirty (30) day  period,  the  arbitrator  named in the
Request shall decide the controversy or claim as sole arbitrator. Otherwise, the
two (2)  arbitrators  appointed  by the  parties  shall  appoint  a third  (3rd)
arbitrator within thirty (30) days after the Respondent has notified Claimant of
the appointment of the Respondent's arbitrator.  When the third (3rd) arbitrator
has accepted the  appointment,  the two (2)  party-appointed  arbitrators  shall
promptly  notify the  parties  of the  appointment.  If the two (2)  arbitrators
appointed  by the  parties  fail to appoint a third  (3rd)  arbitrator  or so to
notify the parties within the time period prescribed above, then the appointment
of the  third  (3rd)  arbitrator  shall  be  made  by the  American  Arbitration
Association,  which shall promptly  notify the parties of the  appointment.  The
third (3rd) arbitrator shall act as Chair of the panel.

                  (f) Other Matters.  This arbitration provision constitutes the
entire  agreement  of the  parties  with  respect  to  its  subject  matter  and
supersedes  all  prior   discussions,   arrangements,   negotiations  and  other
communications on dispute resolution.  This arbitration  provision shall survive
any termination,  amendment,  renewal, extension or expiration of this Agreement
or any agreement executed in connection  herewith or contemplated  hereby unless
the parties  otherwise  expressly agree in writing.  The obligation to arbitrate
any  dispute  shall be binding  upon the  successors  and assigns of each of the
parties.

         Section  11.7.  Counterparts. This  Agreement may be executed in two or
more  counterparts,  each of which shall be deemed to be an original, but all of
which shall constitute one and the same agreement.

         Section 11.8. Entire Agreement.  This Agreement  constitutes the entire
agreement  among the  parties  with  respect to the  subject  matter  hereof and
supersedes all other prior agreements and understandings, both written and oral,
among the parties or any of them with respect to the subject matter hereof.

<PAGE>

         Section 11.9. Parties in Interest. This Agreement shall be binding upon
and inure  solely to the  benefit  of each  party  hereto,  and  nothing in this
Agreement,  express or implied,  is intended to confer upon any other person any
rights  or  remedies  of any  nature  whatsoever  under  or by  reason  of  this
Agreement;   provided,   however,   that  the  parties  hereto  agree  that  the
Shareholders  (including,  without  limitation,  APS) are  intended  third-party
beneficiaries under this Agreement and,  accordingly,  Shareholders  holding, in
the  aggregate,  greater  than  twenty  five  percent  (25%)  of the  previously
distributed portion of the Merger Consideration shall be entitled to enforce the
rights conferred upon the Shareholders under this Agreement.

         Section 11.10.  Enforcement of the Agreement.  The parties hereto agree
that  irreparable  damage would occur in the event that any of the provisions of
this  Agreement  were not performed in accordance  with their  specific terms or
were  otherwise  breached.  It is  accordingly  agreed that the parties shall be
entitled to an injunction or injunctions  to prevent  breaches of this Agreement
and to enforce specifically the terms and provisions hereof.

         Section  11.11.  Validity.  The invalidity or  unenforceability  of any
provision of this Agreement shall not affect the validity or  enforceability  of
any other  provisions  of this  Agreement,  which shall remain in full force and
effect.

                            SHARE EXCHANGE AGREEMENT

         This Share Exchange  Agreement  (this  "Agreement") is made and entered
into as of the 31st day of August,  1999, by and between American Physicians
Service Group, Inc., a Texas corporation ("APS") and David L. Berry, M.D.
(the "Shareholder").

                                R E C I T A L S:

         WHEREAS,  pursuant to that certain Agreement and Plan of Reorganization
(the "Merger  Agreement")  dated December 31, 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 Merger  Agreement (the Merger  Agreement and all such other contracts and
agreements  are  hereinafter   referred  to  collectively  as  the  "Acquisition
Documents"),  Shareholder  acquired 64,642 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 Merger Agreement,  APS
and  Shareholder  entered  into that  certain  Share  Exchange  Agreement  dated
December 31, 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"),  shares of common stock,
par value $0.01, of Prime Medical  Services,  Inc., a Delaware  corporation (the
"Prime Stock"), 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
<PAGE>

purposes hereunder.  As used herein, "Subject Shares" shall refer exclusively to
the Syntera 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 $497,744, and such amount shall not be (a) 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 or (b) affected by
any  forfeiture  or loss of  FemPartners  Shares  withheld at the closing of the
Merger to be conditionally distributed to Shareholder pursuant to the Merger.

         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  December 1, 2001
(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

<PAGE>

contract or agreement to which Shareholder and Syntera,  FemPartners, APS and/or
any of their affiliates are parties; and

                  (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

<PAGE>

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.

         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,  54.8% of the  Subject  Shares  shall be  eligible  for  exchange  as
provided in this Agreement;  and the remaining 45.2% of the Subject Shares, or a
portion thereof,  will only be eligible for an exchange  hereunder in the event,
and only to the extent,  the Clinic (as hereinafter  defined)  achieves  certain
Practice Accrual  Earnings (as hereinafter  defined) levels prior to December 1,
2001 (the "Vesting  Cutoff  Date").  For purposes of this  Agreement,  the terms
"Clinic" and "Practice  Accrual  Earnings"  shall have the meanings set forth in
that certain Management Agreement which is one of the Acquisition Documents. The
Practice  Accrual  Earnings  of Clinic for any twelve (12)  consecutive  monthly
period ending on or prior to the Vesting Cutoff Date is hereinafter  referred to
as the "Clinic PAE." The parties  acknowledge and agree that in the event Clinic
PAE does not exceed $450,000 during any twelve (12) consecutive calendar monthly
period  ending on or prior to the Vesting  Cutoff  Date,  then no portion of the
45.2% of the  Subject  Shares  shall be subject  to  exchange  pursuant  to this
Agreement.  In the event  that,  during any  twelve  (12)  consecutive  calendar
monthly  period  ending on or prior to the Vesting  Cutoff Date,  the Clinic PAE
exceeds  $450,000,  then the percentage of the 45.2% 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 45.2% by a fraction, the numerator of which is the amount by which

<PAGE>

Clinic PAE exceeds  $400,000 (but not greater than  $100,000 in any event),  and
the denominator of which is $100,000.

         EXAMPLE:  The following is provided  purely by way of example only, and
illustrates  the  calculation  of the  number of  Subject  Shares  eligible  for
exchange under this Agreement,  assuming  satisfaction  of all other  conditions
allowing for an exchange pursuant to this Agreement.

                  Assume Clinic PAE is $475,000 for the 12 months ended December
                  31,  1999,  which is the  largest  twelve  (12) month level of
                  Clinic PAE  achieved  in any  period  ended on or prior to the
                  Vesting Cutoff Date.

                  Total Subject Shares eligible for exchange  hereunder would be
                  88.7% of the Subject Shares determined as follows:

                  $475,000 - $400,000        x     45.2%      =     33.9%
                  -------------------
                       $100,000

                                                              +     54.8%
                                                                    -----
                                                                           88.7%

                                                                    =====

         (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

<PAGE>

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

                  (ii) such shares of Prime Stock as is  determined  by dividing
the Gross  Exchange  Value by the average of the "bid" and "ask"  prices for the
Prime  Stock  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

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

                  (iv) 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 or Prime common stock,  APS shall have the right to delay the issuance of
such shares of APS Common or Prime common  stock for up to ninety (90)  calendar
days (the "Market Delay"), if, in APS' sole discretion, an <PAGE>

issuance  of  shares  of APS  Common  or Prime  common  stock  pursuant  to this
Agreement,  or in combination  with any similar  agreement or agreements,  would
depreciate  the  market  value of the APS  Common  or  Prime  common  stock,  as
applicable.

         (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.

         (e) Any shares of APS Common or Prime Stock that  Shareholder  receives
in the exchange  are  hereinafter  referred to as the "New  Shares." The parties
acknowledge and agree that Shareholder shall receive a whole number of shares of
New Shares  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 either
receive a share certificate or certificates for all its New Shares or, if APS is
unable to produce (or caused to be produced) such certificate or certificates by
the Closing  Date,  will receive a copy of a registered  letter sent from APS to
the transfer agent instructing the transfer agent to deliver such certificate or
certificates in the name of Shareholder directly to Shareholder or Shareholder's
designee.

<PAGE>

         6. NEW SHARES  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 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").  Any Prime
Stock  exchanged  hereunder  will be registered  with the Commission and will be
free  of any  and  all  liens,  encumbrances  and  security  interests,  so that
Shareholder  may immediately  sell or otherwise  convey such Prime Stock without
restriction.

                            SHARE EXCHANGE AGREEMENT

         This  Share  Exchange  Agreement  (this  "Agreement")  is made  and
entered  into as of the 31st day of August, 1999, by and between American
Physicians Service Group, Inc., a Texas corporation ("APS") and Michael T.
Breen, M.D. (the "Shareholder").

                                R E C I T A L S:
                                 - - - - - - - -

         WHEREAS,  pursuant to that certain Agreement and Plan of Reorganization
(the "Merger Agreement") dated December 2, 1997, 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
Merger  Agreement  (the  Merger  Agreement  and all  such  other  contracts  and
agreements  are  hereinafter   referred  to  collectively  as  the  "Acquisition
Documents"),  Shareholder  acquired 75,000 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 Merger Agreement,  APS
and  Shareholder  entered  into that  certain  Share  Exchange  Agreement  dated
February 16, 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"),  shares of common stock,
par value $0.01, of Prime Medical  Services,  Inc., a Delaware  corporation (the
"Prime Stock"), 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

<PAGE>

purposes hereunder.  As used herein, "Subject Shares" shall refer exclusively to
the Syntera 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 $375,000, and such amount shall not be (a) 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 or (b) affected by
any  forfeiture  or loss of  FemPartners  Shares  withheld at the closing of the
Merger to be conditionally distributed to Shareholder pursuant to the Merger.

         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  February 16, 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

<PAGE>

contract or agreement to which Shareholder and Syntera,  FemPartners, APS and/or
any of their affiliates are parties; and

                  (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

<PAGE>

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.

         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, all of the Subject Shares are eligible for exchange.

         (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:

<PAGE>

                  (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

                  (ii) such shares of Prime Stock as is  determined  by dividing
the Gross  Exchange  Value by the average of the "bid" and "ask"  prices for the
Prime  Stock  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

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

                  (iv) 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 or Prime common stock,  APS shall have the right to delay the issuance of
such shares of APS Common or Prime common  stock for up to ninety (90)  calendar
days (the "Market Delay"), if, in APS' sole discretion, an issuance of shares of
APS Common or Prime common stock pursuant to this  Agreement,  or in combination
with any similar  agreement or agreements,  would depreciate the market value of
the APS Common or Prime common stock, as applicable.

<PAGE>

         (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.

         (e) Any shares of APS Common or Prime Stock that  Shareholder  receives
in the exchange  are  hereinafter  referred to as the "New  Shares." The parties
acknowledge and agree that Shareholder shall receive a whole number of shares of
New Shares  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 either
receive a share certificate or certificates for all its New Shares or, if APS is
unable to produce (or caused to be produced) such certificate or certificates by
the Closing  Date,  will receive a copy of a registered  letter sent from APS to
the transfer agent instructing the transfer agent to deliver such certificate or
certificates in the name of Shareholder directly to Shareholder or Shareholder's
designee.

         6. New Shares  Transferability.  APS will have registered any shares of
APS Common exchanged  hereunder with the Securities and Exchange Commission (the


<PAGE>

"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 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").  Any Prime
Stock  exchanged  hereunder  will be registered  with the Commission and will be
free  of any  and  all  liens,  encumbrances  and  security  interests,  so that
Shareholder  may immediately  sell or otherwise  convey such Prime Stock without
restriction.

         7.   MISCELLANEOUS.

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

original,  and  all  of  which  together  shall  constitute  one  and  the  same

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:

<PAGE>

                  (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

                  (ii) such shares of Prime Stock as is  determined  by dividing
the Gross  Exchange  Value by the average of the "bid" and "ask"  prices for the
Prime  Stock  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

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

                  (iv) 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 or Prime common stock,  APS shall have the right to delay the issuance of
such shares of APS Common or Prime common  stock for up to ninety (90)  calendar
days (the "Market Delay"), if, in APS' sole discretion, an issuance of shares of
APS Common or Prime common stock pursuant to this  Agreement,  or in combination
with any similar  agreement or agreements,  would depreciate the market value of
the APS Common or Prime common stock, as applicable.

<PAGE>

         (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.

         (e) Any shares of APS Common or Prime Stock that  Shareholder  receives
in the exchange  are  hereinafter  referred to as the "New  Shares." The parties
acknowledge and agree that Shareholder shall receive a whole number of shares of
New Shares  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 either
receive a share certificate or certificates for all its New Shares or, if APS is
unable to produce (or caused to be produced) such certificate or certificates by
the Closing  Date,  will receive a copy of a registered  letter sent from APS to
the transfer agent instructing the transfer agent to deliver such certificate or
certificates in the name of Shareholder directly to Shareholder or Shareholder's
designee.

         6. NEW SHARES  TRANSFERABILITY.  APS will have registered any shares of
APS Common exchanged  hereunder with the Securities and Exchange Commission (the

<PAGE>

"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 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").  Any Prime
Stock  exchanged  hereunder  will be registered  with the Commission and will be
free  of any  and  all  liens,  encumbrances  and  security  interests,  so that
Shareholder  may immediately  sell or otherwise  convey such Prime Stock without
restriction.

         7.  MISCELLANEOUS.

                  (a) FEES AND  EXPENSES.  Each party hereto  agrees to bear all

                  (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

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

parties hereto and their respective heirs, legal representatives, successors and
permitted  assigns.  No party hereto may assign this Agreement,  or any of their

                            SHARE EXCHANGE AGREEMENT

         This Share Exchange  Agreement  (this  "Agreement") is made and entered
into as of the 31st day of August,  1999,  by and  between  American  Physicians
Service Group, Inc., a Texas corporation ("APS") and Robert Casanova,  M.D. (the
"Shareholder").

                                R E C I T A L S:
                                 - - - - - - - -

         WHEREAS,  pursuant to that certain Agreement and Plan of Reorganization
(the "Merger Agreement") dated October 31, 1997, 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
Merger  Agreement  (the  Merger  Agreement  and all  such  other  contracts  and
agreements  are  hereinafter   referred  to  collectively  as  the  "Acquisition
Documents"),  Shareholder  acquired 78,750 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 Merger Agreement,  APS
and Shareholder entered into that certain Share Exchange Agreement dated October
31, 1997 (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"),  shares of common stock,
par value $0.01, of Prime Medical  Services,  Inc., a Delaware  corporation (the
"Prime Stock"), 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

<PAGE>

purposes hereunder.  As used herein, "Subject Shares" shall refer exclusively to
the Syntera 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 $393,750, and such amount shall not be (a) 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 or (b) affected by
any  forfeiture  or loss of  FemPartners  Shares  withheld at the closing of the
Merger to be conditionally distributed to Shareholder pursuant to the Merger.

         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 May 1, 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

<PAGE>

contract or agreement to which Shareholder and Syntera,  FemPartners, APS and/or
any of their affiliates are parties; and

                  (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

<PAGE>

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.

         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, all of the Subject Shares are eligible for exchange.

         (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:

<PAGE>

                  (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

                  (ii) such shares of Prime Stock as is  determined  by dividing
the Gross  Exchange  Value by the average of the "bid" and "ask"  prices for the
Prime  Stock  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

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

                  (iv) 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 or Prime common stock,  APS shall have the right to delay the issuance of
such shares of APS Common or Prime common  stock for up to ninety (90)  calendar
days (the "Market Delay"), if, in APS' sole discretion, an issuance of shares of
APS Common or Prime common stock pursuant to this Agreement, or in combination

<PAGE>

with any similar  agreement or agreements,  would depreciate the market value of
the APS Common or Prime common stock, as applicable.

         (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.

         (e) Any shares of APS Common or Prime Stock that  Shareholder  receives
in the exchange  are  hereinafter  referred to as the "New  Shares." The parties
acknowledge and agree that Shareholder shall receive a whole number of shares of
New Shares  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 either
receive a share certificate or certificates for all its New Shares or, if APS is
unable to produce (or caused to be produced) such certificate or certificates by
the Closing  Date,  will receive a copy of a registered  letter sent from APS to
the transfer agent instructing the transfer agent to deliver such certificate or
certificates in the name of Shareholder directly to Shareholder or Shareholder's
designee.

<PAGE>

         6. NEW SHARES  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 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").  Any Prime
Stock  exchanged  hereunder  will be registered  with the Commission and will be
free  of any  and  all  liens,  encumbrances  and  security  interests,  so that
Shareholder  may immediately  sell or otherwise  convey such Prime Stock without
restriction.

                  (a) FEES AND  EXPENSES.  Each party hereto  agrees to bear all

                            SHARE EXCHANGE AGREEMENT

         This Share Exchange  Agreement  (this  "Agreement") is made and entered
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.

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

                  (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,

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.

                  (d)  INUREMENT.  This  Agreement  shall  be  binding  upon the
parties hereto and

                            SHARE EXCHANGE AGREEMENT

         This Share Exchange  Agreement  (this  "Agreement") is made and entered
into as of the 31st day of August,  1999,  by and  between  American  Physicians
Service Group, Inc., a Texas corporation ("APS") and Donald Columbus,  M.D. (the
"Shareholder").

                                R E C I T A L S:

         WHEREAS,  pursuant to that certain Agreement and Plan of Reorganization
(the "Merger  Agreement") dated September 14, 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 Merger  Agreement (the Merger  Agreement and all such other contracts and
agreements  are  hereinafter   referred  to  collectively  as  the  "Acquisition
Documents"),  Shareholder  acquired 74,448 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 Merger Agreement,  APS
and  Shareholder  entered  into that  certain  Share  Exchange  Agreement  dated
September 15, 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"),  shares of common stock,
par value $0.01, of Prime Medical  Services,  Inc., a Delaware  corporation (the
"Prime Stock"), 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

<PAGE>

purposes hereunder.  As used herein, "Subject Shares" shall refer exclusively to
the Syntera 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  $372,240,  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 1, 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 on 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 (i)  Syntera was not, or would not be, the
named surviving entity after such merger, consolidation or other transaction and
(ii) dissenting shareholders have a legal right of redemption or appraisal.

         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 ninety (90)  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, all of the Subject Shares are eligible for exchange.

         (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 (y) the  Expiration  Date or
(z) if a Lock-Up Period (as hereinafter  defined) is imposed pursuant to Section
6 hereof,  the day on which such  Lock-Up  Period  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) such shares of Prime Stock as is  determined  by dividing
the Gross  Exchange  Value by the average of the "bid" and "ask"  prices for the
Prime  Stock  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

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

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

         (c) 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.

         (d) Any shares of APS Common or Prime Stock that  Shareholder  receives
in the exchange  are  hereinafter  referred to as the "New  Shares." The parties
acknowledge and agree that

<PAGE>

Shareholder  shall receive a whole number of shares of New Shares 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 either receive a share certificate or
certificates  for all its New Shares or, if APS is unable to produce  (or caused
to be produced)  such  certificate  or  certificates  by the Closing Date,  will
receive  a copy of a  registered  letter  sent  from APS to the  transfer  agent
instructing  the transfer agent to deliver such  certificate or  certificates in
the name of Shareholder directly to Shareholder or Shareholder's designee.

         6. NEW SHARES  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

<PAGE>

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 delay the  Closing  Date 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").  Any Prime Stock exchanged  hereunder will be registered with
the Commission and will be free of any and all liens,  encumbrances and security
interests,  so that  Shareholder may immediately  sell or otherwise  convey such
Prime Stock without restriction.

         7.  MISCELLANEOUS.

                  (a) FEES AND  EXPENSES.  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.

<PAGE>

                  (d)  INUREMENT.  This  Agreement  shall  be  binding  upon the
parties hereto and their respective heirs, legal representatives, successors and
permitted  assigns.  No party hereto may assign this Agreement,  or any of their
rights or obligations  hereunder,  without the express prior written  consent of
all parties hereto in each instance.

                  (e)  NOTICES.  Any notices  required or  permitted to be given
under this Agreement  shall be given in writing and shall be deemed received (a)
when  personally  delivered  to the  relevant  party at its address as set forth

         2.  EFFECT  OF  MERGER.  In the event  the  Merger  occurs on or before

Merger,  in return for the Syntera shares (the "FemPartners  Shares"),  shall be
treated as Syntera Shares for all

<PAGE>

purposes hereunder.  As used herein, "Subject Shares" shall refer exclusively to
the Syntera 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 $393,750, and such amount shall not be (a) 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 or (b) affected by
any  forfeiture  or loss of  FemPartners  Shares  withheld at the closing of the
Merger to be conditionally distributed to Shareholder pursuant to the Merger.

         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 May 1, 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

<PAGE>

contract or agreement to which Shareholder  and Syntera,  FemPartners,  APS and/
or any of their  affiliates are parties; and

                  (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

<PAGE>

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.

         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, all of the Subject Shares are eligible for exchange.

         (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:

<PAGE>

                  (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

                  (ii) such shares of Prime Stock as is  determined  by dividing
the Gross  Exchange  Value by the average of the "bid" and "ask"  prices for the
Prime  Stock  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

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

                  (iv) 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 or Prime common stock,  APS shall have the right to delay the issuance of
such shares of APS Common or Prime common  stock for up to ninety (90)  calendar
days (the "Market Delay"), if, in APS' sole discretion, an issuance of shares of
APS Common or Prime common stock pursuant to this  Agreement,  or in combination
with any similar  agreement or agreements,  would depreciate the market value of
the APS Common or Prime common stock, as applicable.

<PAGE>

         (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.

         (e) Any shares of APS Common or Prime Stock that  Shareholder  receives
in the exchange  are  hereinafter  referred to as the "New  Shares." The parties
acknowledge and agree that Shareholder shall receive a whole number of shares of
New Shares  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 either
receive a share certificate or certificates for all its New Shares or, if APS is
unable to produce (or caused to be produced) such certificate or certificates by
the Closing  Date,  will receive a copy of a registered  letter sent from APS to
the transfer agent instructing the transfer agent to deliver such certificate or
certificates in the name of Shareholder directly to Shareholder or Shareholder's
designee.

         6. NEW SHARES  TRANSFERABILITY.  APS will have registered any shares of
APS Common exchanged  hereunder with the Securities and Exchange Commission (the

<PAGE>

"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 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").  Any Prime
Stock  exchanged  hereunder  will be registered  with the Commission and will be
free  of any  and  all  liens,  encumbrances  and  security  interests,  so that
Shareholder  may immediately  sell or otherwise  convey such Prime Stock without
restriction.

         7.   MISCELLANEOUS.

                  (a) FEES AND  EXPENSES.  Each party hereto  agrees to bear all

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

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

parties hereto and their respective heirs, legal representatives, successors and
permitted  assigns.  No party hereto may assign this Agreement,  or any of their

                            SHARE EXCHANGE AGREEMENT

         This  Share  Exchange  Agreement  (this  "Agreement")  is made  and
entered  into as of the 31st  day of August, 1999, by and between American
Physicians Service Group,  Inc., a Texas corporation  ("APS") and M. Reza
Jafarnia, M.D. (the "Shareholder").

                                R E C I T A L S:
                                 - - - - - - - -

         WHEREAS,  pursuant to that certain Asset Purchase Agreement (the "Asset
Purchase  Agreement")  dated  August 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
Asset  Purchase  Agreement  (the  Asset  Purchase  Agreement  and all such other
contracts  and  agreements  are  hereinafter  referred  to  collectively  as the
"Acquisition  Documents"),  Shareholder  acquired  92,557  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  Asset  Purchase
Agreement,  APS  and  Shareholder  entered  into  that  certain  Share  Exchange
Agreement dated August 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"),  shares of common stock,
par value $0.01, of Prime Medical  Services,  Inc., a Delaware  corporation (the
"Prime Stock"), 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

treated as Syntera Shares for all purposes

<PAGE>

hereunder.  As used herein,  "Subject  Shares"  shall refer  exclusively  to the
Syntera  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  $462,785,  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  December 31, 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 have remained,  at any time 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,
following delivery by APS of ten (10) days written notice of such breach or

<PAGE>

default,  and  Shareholder  shall not, on the Closing  Date,  be in breach of or
default under this Agreement, any of the Acquisition Documents or any such other
contract or agreement  (provided,  that in such event,  Shareholder shall have a
period of ten (10) days  following  delivery by APS of written notice thereof to
cure such breach or default and close the share exchange hereunder); and

                  (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

<PAGE>

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.

         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, all of the Subject Shares are eligible for exchange.

         (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 (y) the Expiration  Date, (z)
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

<PAGE>

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

                  (ii) such shares of Prime Stock as is  determined  by dividing
the Gross  Exchange  Value by the average of the "bid" and "ask"  prices for the
Prime  Stock  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

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

                  (iv) 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 or Prime common stock,  APS shall have the right to delay the Closing for
up to ninety (90) calendar days after the Expiration Date (the "Market  Delay"),
if, in APS' sole discretion, an issuance of shares of APS Common or Prime common

<PAGE>

stock pursuant to this Agreement,  or in combination with any similar  agreement
or  agreements,  would  depreciate  the market  value of the APS Common or Prime
common stock, as applicable.

         (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.

         (e) Any shares of APS Common or Prime Stock that  Shareholder  receives
in the exchange  are  hereinafter  referred to as the "New  Shares." The parties
acknowledge and agree that Shareholder shall receive a whole number of shares of
New Shares  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 either
receive a share certificate or certificates for all its New Shares or, if APS is
unable to produce (or caused to be produced) such certificate or certificates by
the Closing  Date,  will receive a copy of a registered  letter sent from APS to
the transfer agent instructing the transfer agent to deliver such certificate or
certificates in the name of Shareholder directly to Shareholder or Shareholder's

<PAGE>

designee  (and APS shall  ensure that  Shareholder  subsequently  receives  such
certificate or certificates).

         6. NEW SHARES  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
to be  received  hereunder,  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 right
to receive stock under this  Agreement that is registered  with the  Commission.
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

                            SHARE EXCHANGE AGREEMENT

         This Share Exchange  Agreement (this  "Agreement") is made  and entered
into as of the 31st day of August,  1999,  by and  between  American  Physicians
Service Group,  Inc., a Texas  corporation  ("APS") and Gary R. Jones, M.D. (the
"Shareholder").

                                R E C I T A L S:
                                 - - - - - - - -

         WHEREAS,  pursuant to that certain Agreement and Plan of Reorganization
(the "Merger  Agreement")  dated June 30, 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
Merger  Agreement  (the  Merger  Agreement  and all  such  other  contracts  and
agreements  are  hereinafter   referred  to  collectively  as  the  "Acquisition
Documents"),  Shareholder  acquired 33,934 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 Merger Agreement,  APS
and  Shareholder  entered into that certain Share Exchange  Agreement dated June
30, 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"),  shares of common stock,
par value $0.01, of Prime Medical  Services,  Inc., a Delaware  corporation (the
"Prime Stock"), 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

<PAGE>

purposes hereunder.  As used herein, "Subject Shares" shall refer exclusively to
the Syntera 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  $169,670,  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 July 1, 2001 (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

<PAGE>

under this Agreement shall automatically terminate and be of no further force or
effect whatsoever.

         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, all of the Subject Shares are eligible for exchange.

         (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:

<PAGE>

                  (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

                  (ii) such shares of Prime Stock as is  determined  by dividing
the Gross  Exchange  Value by the average of the "bid" and "ask"  prices for the
Prime  Stock  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

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

                  (iv) 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 or Prime common stock,  APS shall have the right to delay the issuance of
such shares of APS Common or Prime common  stock for up to ninety (90)  calendar
days after the Closing Date (the "Market  Delay"),  if, in APS' sole discretion,
an  issuance  of shares of APS Common or Prime  common  stock  pursuant  to this
Agreement,  or in combination  with any similar  agreement or agreements,  would
depreciate  the  market  value of the APS  Common  or  Prime  common  stock,  as
applicable.

<PAGE>

         (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.

         (e) Any shares of APS Common or Prime Stock that  Shareholder  receives
in the exchange  are  hereinafter  referred to as the "New  Shares." The parties
acknowledge and agree that Shareholder shall receive a whole number of shares of
New Shares  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 either
receive a share certificate or certificates for all its New Shares or, if APS is
unable to produce (or caused to be produced) such certificate or certificates by
the Closing  Date,  will receive a copy of a registered  letter sent from APS to
the transfer agent instructing the transfer agent to deliver such certificate or
certificates in the name of Shareholder directly to Shareholder or Shareholder's
designee.

         6. NEW SHARES  TRANSFERABILITY.  APS will have registered any shares of
APS Common exchanged  hereunder with the Securities and Exchange Commission (the

<PAGE>

"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 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").  Any Prime
Stock  exchanged  hereunder  will be registered  with the Commission and will be
free  of any  and  all  liens,  encumbrances  and  security  interests,  so that
Shareholder  may immediately  sell or otherwise  convey such Prime Stock without
restriction.

<PAGE>

         7.       MISCELLANEOUS.

                  (a) FEES AND  EXPENSES.  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.

                  (d)  INUREMENT.  This  Agreement  shall  be  binding  upon the
parties hereto and their respective heirs, legal representatives, successors and
permitted  assigns.  No party hereto may assign this Agreement,  or any of their
rights or obligations  hereunder,  without the express prior written  consent of
all parties hereto in each instance.

                  (e)  NOTICES.  Any notices  required or  permitted to be given
under this Agreement  shall be given in writing and shall be deemed received (a)
when  personally  delivered

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

<PAGE>

contract or agreement to which Shareholder and Syntera,  FemPartners, APS and/or
any of their affiliates are parties; and

                  (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

                  (d) If the Merger has not occurred on or prior to December 31,

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

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

<PAGE>

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.

         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, all of the Subject Shares are eligible for exchange.

         (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:

<PAGE>

                  (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

                  (ii) such shares of Prime Stock as is  determined  by dividing
the Gross  Exchange  Value by the average of the "bid" and "ask"  prices for the
Prime  Stock  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

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

                  (iv) 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 or Prime common stock,  APS shall have the right to delay the issuance of
such shares of APS Common or Prime common  stock for up to ninety (90)  calendar
days (the "Market Delay"), if, in APS' sole discretion, an issuance of shares of
APS Common or Prime common stock pursuant to this  Agreement,  or in combination
with any similar  agreement or agreements,  would depreciate the market value of
the APS Common or Prime common stock, as applicable.

<PAGE>

         (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.

         (e) Any shares of APS Common or Prime Stock that  Shareholder  receives
in the exchange  are  hereinafter  referred to as the "New  Shares." The parties
acknowledge and agree that Shareholder shall receive a whole number of shares of
New Shares  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 either
receive a share certificate or certificates for all its New Shares or, if APS is
unable to produce (or caused to be produced) such certificate or certificates by
the Closing  Date,  will receive a copy of a registered  letter sent from APS to
the transfer agent instructing the transfer agent to deliver such certificate or
certificates in the name of Shareholder directly to Shareholder or Shareholder's
designee.

         6. NEW SHARES  TRANSFERABILITY.  APS will have registered any shares of
APS Common exchanged  hereunder with the Securities and Exchange Commission (the

<PAGE>

"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 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").  Any Prime
Stock  exchanged  hereunder  will be registered  with the Commission and will be
free  of any  and  all  liens,  encumbrances  and  security  interests,  so that
Shareholder  may immediately  sell or otherwise  convey such Prime Stock without
restriction.

                            SHARE EXCHANGE AGREEMENT

         This  Share  Exchange  Agreement  (this  "Agreement")  is made  and
entered  into as of the 31st day of August, 1999, by and between  American
Physicians  Service Group,  Inc., a Texas  corporation  ("APS") and Lawrence M.
Slocki, M.D. (the "Shareholder").

                                R E C I T A L S:
                                 - - - - - - - -

         WHEREAS,  pursuant to that certain Asset Purchase Agreement (the "Asset
Purchase  Agreement")  dated January 25, 1999,  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
Asset  Purchase  Agreement  (the  Asset  Purchase  Agreement  and all such other
contracts  and  agreements  are  hereinafter  referred  to  collectively  as the
"Acquisition  Documents"),  Shareholder  acquired  18,771  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  Asset  Purchase
Agreement,  APS  and  Shareholder  entered  into  that  certain  Share  Exchange
Agreement dated January 25, 1999 (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"),  shares of common stock,
par value $0.01, of Prime Medical  Services,  Inc., a Delaware  corporation (the
"Prime Stock"), 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 Shares, unless the Merger occurs

<PAGE>

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 $131,397,  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  January 22, 2002
(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

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 ninety (90)  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

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:

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 or Prime common stock,  APS shall have the right to delay the issuance of
such shares of APS Common or Prime common  stock for up to ninety (90)  calendar
days (the "Market Delay"), if, in APS' sole discretion, an issuance of shares of
APS Common or Prime common stock pursuant to this  Agreement,  or in combination
with any similar  agreement or agreements,  would depreciate the market value of
the APS Common or Prime common stock, as applicable.

         (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

engage in the transactions contemplated hereby, and (ii) that Shareholder owns

<PAGE>

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.

         (e) Any shares of APS Common or Prime Stock that  Shareholder  receives

receive a share certificate or certificates for all its New Shares or, if APS is
unable to produce (or caused to be produced) such certificate or certificates by
the Closing  Date,  will receive a copy of a registered  letter sent from APS to
the transfer agent instructing the transfer agent to deliver such certificate or
certificates in the name of Shareholder directly to Shareholder or Shareholder's
designee.

         6. NEW SHARES  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

<PAGE>

the  Determination  Date or before or after  Shareholder  delivers  any Exchange

Notwithstanding anything contained herein to the contrary, in the event that APS

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").  Any Prime
Stock  exchanged  hereunder  will be registered  with the Commission and will be
free  of any  and  all  liens,  encumbrances  and  security  interests,  so that
Shareholder  may immediately  sell or otherwise  convey such Prime Stock without
restriction.

<PAGE>

                                    ARTICLE I

                                    THE LOANS

         1.1 THE LOANs.  Lender agrees to lend and Borrower  agrees to borrow an
amount not to exceed the Maximum Principal Amount (the "Loans") on the terms and
conditions set forth herein. The Loans will be evidenced by the Note.

         1.2  SECURITY.  Borrower  will  grant to  Lender  a lien  and  security
interest in the Collateral and agrees to do all things  necessary to perfect the
liens and security interests of Lender in such Collateral.

                                   ARTICLE II

                   DESCRIPTION OF CREDIT FACILITIES; ADVANCES

         2.1 MAXIMUM  PRINCIPAL AMOUNT.  The maximum aggregate  principal amount
(the  "Maximum  Principal  Amount")  of credit  extended  by Lender to  Borrower
hereunder that will be outstanding at any time is the lesser of (i) $500,000, or
(ii) the Borrowing Base (as defined herein).  The borrowing base (the "Borrowing
Base")  equals  ninety  percent  (90%)  of  the  value  of  Qualified  Accounts.
"Qualified  Account"  means any right of Borrower  to receive  payment for goods
sold or  leased or  services  rendered  in the  ordinary  course  of  Borrower's
business, but only if such right (i) is less than 90 days old, (ii) has not been
sold to any other  person or entity and Borrower has not agreed to any such sale
and (iii) has not previously  been deemed by Lender (in its sole  discretion) to
be ineligible for consideration as a Qualified Account.

         2.2  REVOLVING  LINE OF  CREDIT.  Subject to and in  reliance  upon the
terms, conditions,  representations and warranties hereinafter set forth, Lender
agrees to make advances (an  "Advance") to Borrower from time to time during the
period from the date hereof to and including July 1, 2000  ("Maturity  Date") in
an aggregate amount not to exceed the Maximum Principal Amount of the Note. Each
Advance must be either $10,000 or a higher integral  multiple of $10,000.  Funds
borrowed and repaid may be reborrowed,  so long as all  conditions  precedent to
Advances are met. In addition to providing funds to Borrower for working capital
and for other general business purposes of Borrower,  one of the purposes of the
Loans is to enable  Borrower  to fully pay,  and  obtain (in form and  substance
satisfactory  to  Lender)  a  release  and  discharge  of (the  "Access  Capital
Release"),  any  and all  liabilities,  obligations,  debts,  claims  and  liens
(collectively,  the "Access Capital Claims") owed by Borrower to Access Capital,
Inc., a New York corporation ("Access Capital"),  including, without limitation,
all obligations under that certain factoring agreement,  as amended, dated as of
February 11, 1998,  by and between  Access  Capital and Borrower  (formerly  Eco
Acquisition,  Inc. d/b/a Eco-Systems,  Inc.), and any replacements  thereof (the
"Factoring Agreement").  Accordingly, and notwithstanding anything herein to the
contrary,  Lender  may,  in its  sole  discretion,  refuse  to make  one or more
Advances hereunder unless and until all Access Capital Claims are fully paid and
Borrower has delivered to Lender the Access Capital Release.

         2.3 Interest and  Repayment.  Borrower  shall pay the aggregate  unpaid
principal amount of all Advances in accordance with the terms of the Note, which
shall evidence the  indebtedness  resulting from such Advances.  Interest on the
Advances  shall be due and  payable  in the manner and at the times set forth in
the Note, with final maturity of the Note being on or before July 1, 2000.

         2.4 MAKING  ADVANCES.  Each  Advance  shall be made within two business
days of written notice (or telephonic notice confirmed in writing) given by noon
(Austin,  Texas  time)  on a  business  day of  Lender  by  Borrower  to  Lender
specifying  the amount and date thereof (which may be the same business day) and
if sent by wired  funds,  at Lender's  option,  the wiring  instructions  of the
deposit account of Borrower to which such Advance is to be deposited. All or a

<PAGE>

portion of the legal and accounting costs and expenses incurred by Lender or its
affiliates in connection with the preparation,  negotiation and entering into of
the Loan Documents may, at the sole election of Lender, be considered an advance
by Lender under this Note.

         2.5  PAYMENTS  AND  COMPUTATIONS.  Borrower  shall  make  each  payment
hereunder  and under the Note on the day when due in lawful  money of the United
States of America to Lender at Lender's Address for payment in same day funds or
other payment  method  acceptable to Lender.  All repayments of principal on the
Note shall be in a minimum amount of $10,000,  or a higher integral  multiple of
$10,000.  All  computations  of interest shall be made by Lender on the basis of
the actual number of days  (including  the first day but excluding the last day)
in the year (365 or 366, as the case may be) elapsed,  but in no event shall any
such  computation  result in an amount of interest that would cause the interest
contracted for, charged or received by Lender to be in excess of the amount that
would be payable at the Highest Lawful Rate, as herein defined.

                                   ARTICLE III

                             CONDITIONS TO ADVANCES

         3.1 Condition Precedent to Initial Advance. The obligation of Lender to

amounts an Advance under this Agreement) and (h) Lender shall have received such
other approvals,  opinions,  documents,  certificates or evidences as Lender may
reasonably  request (in form and substance  reasonably  satisfactory to Lender).
Each request for an Advance  shall be deemed a  representation  by Borrower that

(except as  otherwise  required  by  statute),  may,  at  Lender's  option:  (i)
terminate  its  obligation  to  fund  Advances   hereunder;   (ii)  declare  the
Indebtedness,  in whole or in part,  immediately  due and payable;  and/or (iii)
exercise any other rights and remedies,  including foreclosure rights, available
to Lender under this  Agreement,  any other Loan Document,  or applicable  laws;
except that upon the  occurrence of an Event of Default  described in subsection
7.1(f), all the Indebtedness shall automatically be immediately due and payable,
and  Lender's   obligation  to  fund  Advances  hereunder  shall   automatically
terminate,  without notice of any kind (including  without  limitation notice of
intent  to  accelerate  and  notice  of  acceleration)  to  Borrower  or to  any
guarantor,  or to any surety or  endorser of the Note,  or to any other  person.
Borrower and each guarantor,  surety,  and endorser of the Note, and any and all
other parties  liable for the  Indebtedness  or any part thereof,  waive demand,
notice of intent to  demand,  presentment  for  payment,  notice of  nonpayment,
protest,  notice of  protest,  grace,  notice of  dishonor,  notice of intent to

         7.3 RIGHT OF SET-OFF. Borrower hereby authorizes Lender, to the maximum
extent permitted under and in accordance with applicable laws, at any time after
the  occurrence  of an  Event of  Default,  to  set-off  and  apply  any and all
deposits, funds or assets at any time held and any and all other indebtedness at
any time owing by Lender to or for the credit or the account of Borrower against
any and all  Indebtedness,  whether or not Lender  exercises  any other right or
remedy hereunder and whether or not such Indebtedness are then matured.

                                  ARTICLE VIII

                          GENERAL TERMS AND CONDITIONS

         8.1  NOTICES.  All  notices,  demands,  requests,  approvals  and other
communications  required or permitted hereunder shall be in writing and shall be
deemed to have been given when (a) presented  personally,  or (b) three (3) days
after  deposited in a regularly  maintained mail receptacle of the United States
Postal Service,  postage prepaid,  certified,  return receipt requested,  or (c)
upon receipt of confirmation after sending by facsimile transmission,  addressed
to  Borrower  or  Lender,  as the case may be, at the  respective  addresses  or
facsimile  number for notice set forth on the first page of this  Agreement,  or
such other  address or  facsimile  number as Borrower or Lender may from time to
time designate by written notice to the other.

         8.2 ENTIRE AGREEMENT AND MODIFICATIONS.  The Loan Documents  constitute
the entire  understanding  and agreement between the undersigned with respect to
the  transactions  arising in connection  with the Loans and supersede all prior
written  or oral  understandings  and  agreements  between  the  undersigned  in
connection therewith. No provision of this Agreement or the other Loan Documents
may be modified,  waived, or terminated except by instrument in writing executed
by the party against whom a modification, waiver, or termination is sought to be
enforced,  and, in the case of Lender,  executed by a Vice  President  or higher
level officer of Lender.

         8.3 SEVERABILITY. In case any of the provisions of this Agreement shall
for  any  reason  be  held  to  be  invalid,  illegal,  or  unenforceable,  such
invalidity, illegality, or unenforceability shall not affect any other provision
hereof,  and this Agreement shall be construed as if such invalid,  illegal,  or
unenforceable provision had never been contained herein.

         8.4  CUMULATIVE  RIGHTS  AND NO  WAIVER.  Lender  shall have all of the
rights and remedies  granted in the Loan  Documents  and  available at law or in
equity,  and these  same  rights and  remedies  shall be  cumulative  and may be
pursued  separately,  successively,  or concurrently  against  Borrower,  or the
Collateral or any part thereof, at the sole discretion of Lender. Lender's delay
in  exercising  any right shall not operate as a waiver  thereof,  nor shall any
single or partial  exercise by Lender of any right  preclude any other or future
exercise thereof or the exercise of any other right. Any of Borrower's covenants
and  agreements  may be  waived  by  Lender  but only in  writing  signed  by an
authorized officer of Vice President level or higher of Lender or any subsequent
owner or holder of the Note. Borrower expressly waives any presentment,  demand,
protest,  notice  of  default,  notice  of  intent  to  accelerate,   notice  of
acceleration,  notice of intent to demand payment,  or other notice of any kind.
No notice to or  demand  on  Borrower  in any case  shall,  of  itself,  entitle
Borrower  to any  other  or  further  notice  or  demand  in  similar  or  other
circumstances.  No delay or omission by Lender in exercising  any power or right
hereunder  shall  impair  any such  right or power or be  construed  as a waiver
thereof, or the exercise of any other right or power hereunder.

         8.5  FORM  AND  SUBSTANCE.  All  documents,   certificates,   insurance
policies,  and other items required  under this Agreement to be executed  and/or
delivered to Lender shall be in form and substance  reasonably  satisfactory  to
Lender.

<PAGE>

         8.6 LIMITATION ON INTEREST: Maximum Rate. Lender and Borrower intend to
contract in strict  compliance  with  applicable  usury law from time to time in
effect.  To effectuate this intention,  Lender and Borrower  stipulate and agree
that none of the terms and provisions of the Note and any other  agreement among
such parties, whether now existing or arising hereafter, shall ever be construed
as a contract to pay interest for the use,  forbearance or detention of money in
excess of the Maximum Rate. If, from any possible  construction of any document,
interest would otherwise be payable to Lender in excess of the Maximum Rate, any
such  construction  shall be subject to the  provisions of this Section and such
document  shall be  automatically  reformed and the  interest  payable to Lender
shall be  automatically  reduced to the Maximum Rate permitted under  applicable
law,  without the  necessity of the  execution of any amendment or new document.
Neither  Borrower,  endorsers or other persons now or hereafter  becoming liable
for payment of any portion of the  principal  or interest of the Note shall ever
be liable for any  unearned  interest on the  principal  amount or shall ever be
required  to pay  interest  thereon  in excess of the  Maximum  Rate that may be
lawfully  charged under  applicable law from time to time in effect.  Lender and
any subsequent holder of the Note expressly  disavows any intention to charge or
collect  unearned  or  excessive  interest  or finance  charges in the event the
maturity of the Note, is accelerated. If the maturity of the Note is accelerated
for any reason, whether as a result of a default under the Note, or by voluntary
prepayment,  or otherwise,  any amounts constituting interest, or adjudicated as
constituting  interest,  which  are  then  unearned  and  have  previously  been
collected  by Lender or any  subsequent  holder of the Note  shall be applied to
reduce the principal balance thereof then outstanding, or if such amounts exceed
the unpaid  balance of principal,  the excess shall be refunded to Borrower.  In
the event Lender or any subsequent holder of the Note ever receives, collects or
applies  as  interest  any  amounts  constituting  interest  or  adjudicated  as
constituting  interest which would otherwise  increase the interest to an amount
in excess of the amount  permitted under applicable law, such amount which would
be excessive  interest shall be applied to the reduction of the unpaid principal
balance of the Note, and, if the principal balances of the Note is paid in full,
any remaining  excess shall be paid to Borrower.  In determining  whether or not
the  interest  paid or payable  under the  specific  contingencies  exceeds  the
Maximum Rate  allowed by  applicable  law,  Borrower  and Lender  shall,  to the
maximum  extent   permitted   under   applicable  law,  (i)   characterize   any
non-principal  payment as an expense,  fee or premium,  rather than as interest;
(ii) exclude  voluntary  prepayments  and the effect  thereof;  (iii)  amortize,
prorate,  allocate  and spread,  in equal  parts,  the total  amount of interest
throughout the entire  contemplated  term of the  applicable  Note (as it may be
renewed and extended) so that the interest rate is uniform throughout the entire
term of the Note.  The terms and  provisions  of this section  shall control and
supersede  every other provision of all existing and future  agreements  between
Lender and Borrower. As used in this Agreement, "Maximum Rate" means the maximum
non-usurious  interest  rate  that  at any  time or  from  time  to time  may be
contracted for, taken, reserved,  charged or received on the unpaid principal or
accrued  past due  interest  under  applicable  law and may be greater  than the
applicable  rate,  the parties hereby  stipulating  and agreeing that Lender may
contract for, take,  reserve,  charge or receive interest up to the Maximum Rate
without penalty under any applicable law; and "applicable law" means the laws of
the State of Texas or the laws of the United States of America,  whichever  laws
allow the greater interest,  as such laws now exist or may be changed or amended
or come into effect in the future.  In the event  applicable law provides for an
interest  ceiling under  Chapter One of Title 79, Texas  Revised Civil  Statutes
Annotated, as amended, that ceiling shall be the indicated rate ceiling, subject
to any right  Lender may have in the future to change the method of  determining
the Maximum Rate.

         8.7      NO THIRD  PARTY  BENEFICIARY.  This Agreement  is for the sole
benefit  of Lender and  Borrower  and is not for the benefit of any third party.

         8.8  BORROWER  IN  CONTROL.  In no  event  shall  Lender's  rights  and
interests  under the Loan Documents be construed to give Lender the right to, or
be deemed to indicate that Lender is in control of the  business,  management or
properties  of Borrower  or has power over the daily  management  functions  and
operating decisions made by Borrower.

<PAGE>

         8.9 USE OF FINANCIAL AND OTHER INFORMATION. Borrower agrees that Lender
shall be  permitted  to  investigate  and  verify  the  accuracy  of any and all
information furnished to Lender in connection with the Loan Documents, including
without limitation financial  statements,  and to disclose such information,  or
provide  copies of such  information,  to  representatives  appointed by Lender,
including  independent  accountants,  agents,  attorneys,  asset  investigators,
appraisers   and  any  other  persons   deemed   necessary  by  Lender  to  such
investigation.

         8.10 PARTICIPATION OR SALE OF LOAN. Lender shall have the right to sell
the Note, or participation  interests in the Note to any other person or entity.
Borrower  shall  execute,  acknowledge  and  deliver  any  and  all  instruments
requested by Lender to satisfy such purchasers or  participants  that the unpaid
indebtedness  evidenced  by the  Note  is  outstanding  upon  the  terms  of the
provisions  set out in the  Loan  Documents.  Lender  shall  have  the  right to
disclose in confidence  such  financial  information  regarding  Borrower or the
Collateral  as may be necessary  to complete  any sale or attempted  sale of the
Note or  participations  or  attempted  participations  in the Loans,  including
without  limitation  all  Loan  Documents,  financial  statements,  projections,
internal memoranda, audits, reports, payment history, appraisals and any and all
other  information and  documentation in Lender's files relating to Borrower and
the Collateral.  This authorization shall be irrevocable in favor of Lender, and
Borrower  waives  any  claims  that  they may have  against  Lender or the party
receiving  information  from  Lender  regarding  disclosure  of  information  in
Lender's files, and further waive any alleged damages which they may suffer as a
result of such disclosure.

         8.11  FURTHER  ASSURANCES.  Borrower  agrees to execute  and deliver to
Lender,  promptly upon request from Lender,  such other and further documents as
may be  reasonably  necessary or  appropriate  to  consummate  the  transactions
contemplated  herein or to perfect the liens and security interests covering the
Collateral.

         8.12 NUMBER AND GENDER. Whenever used herein, the singular number shall
include the plural and the plural the singular,  and the use of any gender shall
be applicable to all genders. The duties, covenants, obligations, and warranties
of Borrower in this Agreement shall be joint and several obligations of Borrower
and of each Borrower if more than one.

         8.13 CAPTIONS.  The captions,  headings,  and arrangements used in this
Agreement are for convenience only and do not in any way affect, limit, amplify,
or modify the terms and provisions hereof.

         8.14  CONTINUING  AGREEMENT.  This is a  continuing  agreement  and all
rights,  powers,  and remedies of Lender under this Agreement and the other Loan
Documents shall continue in full force and effect until the Note is paid in full
as the same  becomes  due and  payable  and all other  Indebtedness  is paid and
discharged, until Lender has no further obligation to advance moneys to Borrower
under this Agreement, and until Lender, upon request of Borrower, has executed a
written termination statement.  Furthermore,  the parties contemplate that there
may be times when no Indebtedness is owing, but notwithstanding such occurrence,
this Agreement (and all other Loan Documents) shall remain valid and shall be in
full force and effect as to subsequent Indebtedness and Advances,  provided that
Lender has not executed a written termination statement.

         8.15  Applicable  Law. THIS AGREEMENT AND THE LOAN  DOCUMENTS  SHALL BE
GOVERNED BY AND CONSTRUED IN ACCORDANCE  WITH THE LAWS OF THE STATE OF TEXAS AND
THE LAWS OF THE UNITED STATES APPLICABLE TO TRANSACTIONS WITHIN SUCH STATE.

<PAGE>

         8.16     NO ORAL AGREEMENTS. THE WRITTEN LOAN AGREEMENT  REPRESENTS THE
FINAL AGREEMENT  BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED  BY EVIDENCE OF
PRIOR, CONTEMPORANEOUS,  OR  SUBSEQUENT ORAL AGREEMENTS  OF THE PARTIES.  THERE
ARE NO UNWRITTEN  ORAL AGREEMENTS BETWEEN THE PARTIES.

         (a)  RATE:  The  principal  balance  of  this  Note  from  time to time
remaining  unpaid prior to maturity shall bear interest at the Interest Rate per
annum stated above.  Interest  shall be calculated on the amount of each advance
of the Principal Amount of this Note from the date of each such advance.

         (b) MAXIMUM LAWFUL  INTEREST:  The term "Maximum Lawful Rate" means the
maximum rate of interest and the term "Maximum  Lawful Amount" means the maximum
amount of interest that is permissible under applicable state or federal law for
the type of loan  evidenced  by this Note and the other Loan  Documents.  If the
Maximum  Lawful  Rate is  increased  by  statute  or other  governmental  action
subsequent to the date of this Note,  then the new Maximum  Lawful Rate shall be
applicable  to this Note  from the  effective  date  thereof,  unless  otherwise
prohibited by applicable law.

         (c)  SPREADING OF  INTEREST:  Because of the  possibility  of irregular
periodic  balances of principal or premature  payment,  the total  interest that
will accrue  under this Note cannot be  determined  in advance.  Lender does not
intend to contract for, charge,  or receive more than the Maximum Lawful Rate or
Maximum  Lawful  Amount  permitted  by  applicable  state or federal law, and to
prevent  such an  occurrence  Lender  and  Borrower  agree  that all  amounts of
interest,  whenever contracted for, charged, or received by Lender, with respect
to the loan of money  evidenced  by this  Note,  shall be spread,  prorated,  or
allocated over the full period of time this Note is unpaid, including the period
of any renewal or extension of this Note.  If demand for payment of this Note is
made by Lender  prior to the full  stated  term,  the total  amount of  interest
contracted for, charged, or received to the time of such demand shall be spread,
prorated, or allocated along with any interest thereafter accruing over the full
period of time that this Note  thereafter  remains  unpaid  for the  purpose  of
determining if such interest exceeds the Maximum Lawful Amount.

         (d) EXCESS INTEREST: At maturity (whether by acceleration or otherwise)
or on earlier final payment of this Note,  Lender shall compute the total amount
of interest  that has been  contracted  for,  charged,  or received by Lender or
payable by  Borrower  under this Note and  compare  such  amount to the  Maximum
Lawful  Amount  that could have been  contracted  for,  charged,  or received by
Lender. If such computation  reflects that the total amount of interest that has
been  contracted  for,  charged,  or  received  by Lender or payable by Borrower
exceeds the Maximum  Lawful  Amount,  then Lender shall apply such excess to the
reduction of the  principal  balance and not to the payment of  interest;  or if
such excess interest exceeds the unpaid principal balance,  such excess shall be
refunded to  Borrower.  This  provision  concerning  the  crediting or refund of
excess  interest  shall control and take  precedence  over all other  agreements
between  Borrower  and  Lender so that  under no  circumstances  shall the total
interest  contracted  for,  charged,  or received  by Lender  exceed the Maximum
Lawful Amount.

         (e) INTEREST AFTER DEFAULT:  At Lender's  option,  the unpaid principal
balance  shall  bear  interest  after  maturity   (whether  by  acceleration  or
otherwise) at the "Default  Interest Rate." The Default  Interest Rate shall be,
at Lender's option,  (i) the Maximum Lawful Rate, if such Maximum Lawful Rate is
established  by  applicable  law; or (ii) the Interest  Rate stated on the first
page of this Note plus five (5) percentage  points, if no Maximum Lawful Rate is
established  by applicable  law; or (iii) eighteen  percent (18%) per annum;  or
(iv) such lesser rate of interest as Lender in its sole discretion may choose to
charge;  but never  more than the  Maximum  Lawful  Rate or at a rate that would
cause the total  interest  contracted  for,  charged,  or  received by Lender to
exceed the Maximum Lawful Amount.

         (f)  DAILY  COMPUTATION  OF  INTEREST:   To  the  extent  permitted  by
applicable  law,  Lender at its option will calculate the per diem interest rate
or amount  based on the  actual  number of days in the year (365 or 366,  as the


<PAGE>

case may be), and charge that per diem  interest  rate or amount each day. In no
event shall  Lender  compute the interest in a manner that would cause Lender to
contract for,  charge,  or receive interest that would exceed the Maximum Lawful
Rate or the Maximum Lawful Amount.

2.       DEFAULT PROVISIONS:

         (a) EVENTS OF DEFAULT AND ACCELERATION OF MATURITY: LENDER MAY, WITHOUT
NOTICE OR DEMAND  (EXCEPT AS  OTHERWISE  REQUIRED BY  STATUTE),  ACCELERATE  THE
MATURITY OF THIS NOTE AND DECLARE THE ENTIRE  UNPAID  PRINCIPAL  BALANCE AND ALL
ACCRUED INTEREST AT ONCE DUE AND PAYABLE IF:

                  (i)      There is default in the payment of any installment of
principal,  interest,  or any other sum required to be paid under the terms of
this Note or any of the Loan Documents; or

                  (ii)  There is  default in the  performance  of any  covenant,

AND AGREES TO ONE OR MORE  EXTENSIONS FOR ANY PERIOD OR PERIODS OF TIME, AND ANY
PARTIAL PAYMENTS,  BEFORE OR AFTER MATURITY,  WITHOUT PREJUDICE TO THE HOLDER OF

ALL RENEWALS, EXTENSIONS, REARRANGEMENTS, AND MODIFICATIONS OF THIS NOTE.

         (c) NON-WAIVER BY LENDER: Any previous extension of time,  forbearance,
failure to pursue some remedy,  acceptance  of late  payments,  or acceptance of
partial  payment by Lender,  before or after  maturity,  does not  constitute  a
waiver by Lender of its subsequent  right to strictly  enforce the collection of
this Note according to its terms.

         (d)      OTHER REMEDIES NOT REQUIRED:  Lender shall not be required to
first file suit, exhaust all remedies, or enforce its rights against any
security in order to enforce payment of this Note.

         (e) JOINT AND SEVERAL LIABILITY: Each Borrower who signs this Note, and
all of the  other  parties  liable  for  the  payment  of  this  Note,  such  as
guarantors,  endorsers,  and sureties,  are jointly and severally liable for the
payment of this Note.

         (f) ATTORNEY'S  FEES: If Lender requires the services of an attorney to
enforce the payment of this Note or the performance of the other Loan Documents,
or if this Note is collected through any lawsuit, probate,  bankruptcy, or other
judicial  proceeding,  Borrower  agrees to pay  Lender  an  amount  equal to its
reasonable  attorney's fees and other collection  costs. This provision shall be
limited by any applicable statutory  restrictions  relating to the collection of
attorney's fees.

                               DEBTOR'S WARRANTIES

         Debtor represents and warrants to Secured Party as follows:

         3.1  FINANCING   STATEMENTS.   No  financing   statement  covering  the
Collateral  is or will be on file in any public  office,  except  the  financing
statements  relating to this Security  Interest,  and those described in Exhibit
"B". In the past five (5) years,  Debtor has not used or done business under any
name other than  "Eco-Acquisition,  Inc.,"  "Eco-Systems"  or its legal name set
forth on the first page of this Agreement.

         3.2 OWNERSHIP.  Debtor owns the Collateral free from any setoff, claim,
restriction,  lien, security interest, or encumbrance except liens for taxes not
yet due, the Security Interest and those described in Exhibit "B".

         3.3 FIXTURES AND ACCESSIONS.  None of the Collateral is affixed to real
estate or is an accession to any goods,  or will become a fixture or  accession,
except as expressly set out herein.

         3.4 CLAIMS OF  DEBTORS ON  COLLATERAL.  No  account  debtors  and other
obligors whose debts or obligations are part of the Collateral have any right to
setoffs, counterclaims, or adjustments, or any defenses in connection therewith.

         3.5      ACCURACY  OF  FINANCIAL  STATEMENTS.  All representations  and
warranties  made by Debtor  with respect to its financial data are true in all
material respects.

         3.6      POWER AND AUTHORITY.  Debtor has full power and authority to
make this Agreement.

<PAGE>

         3.7 PRINCIPAL PLACE OF BUSINESS.  Debtor's  principal place of business

records.

         3.8 LOCATION OF COLLATERAL.  All of Debtor's inventory and equipment is
located at the real  properties  described  in Exhibit "C"  attached  hereto and
incorporated  herein by reference or at its principal place of business.  Debtor
has exclusive  possession  and control of its inventory and  equipment.  None of
Debtor's  inventory  or  equipment is evidenced by a document (as defined in the
Texas UCC). All  instruments,  chattel paper,  securities,  and  certificates of
title  comprising  any part of the  Collateral  have been  delivered  to Secured
Party. Before Debtor shall acquire additional inventory and equipment subject to
this  Agreement and store or use such property at a location other than the real
properties  described in Exhibit "C" or remove existing  inventory and equipment
to a location other than the real  properties  described in Exhibit "C",  Debtor
shall first notify Lender of such location and comply with Section 4.7 hereof.

Party's obtaining  possession of all Debtor's  documents,  instruments,  chattel
paper, securities, and certificates of title, and upon Secured Party's obtaining
control of Debtor's Investment Property, the Security Interest will constitute a
valid and perfected lien upon and security  interest in the  Collateral.  In the
event another  secured party has  possession of Debtor's  assets for  perfection
purposes,  such secured party's  possession shall be deemed possession on behalf
of Secured Party to the extent of Secured Party's subordinate security interest,
and when possession is no longer required for any other security interest,  then
possession shall be transferred to Secured Party.

         3.10 SOLVENCY.  As of the date hereof,  and after giving effect to this
Agreement and the completion of all other transactions contemplated by Debtor at

         Debtor covenants and agrees that:

         4.1      INDEBTEDNESS  AND THIS  AGREEMENT.  Debtor  shall pay the
Indebtedness  in  accordance  with its terms and shall promptly  perform all of
his (or its)  agreements  herein and in any other  agreements  between him
(or it) and Secured Party.

         4.2 OWNERSHIP OF COLLATERAL. At the time Debtor grants to Secured Party
a security  interest  in any  Collateral,  Debtor  shall be the  absolute  owner
thereof and shall have the right to grant such security  interest.  Debtor shall
defend the Collateral  against all claims and demands of all persons at any time
claiming any interest  therein  adverse to Secured Party.  Debtor shall keep the
Collateral free from all liens and security interests.

<PAGE>

         4.3  INSURANCE.  Debtor  shall  insure the  Collateral  with  companies
acceptable  to Secured  Party  against  such  casualties  and in such amounts as
Secured Party shall  require.  All insurance  policies  shall be written for the
benefit of Debtor and Secured Party as their  interests may appear,  or in other
form satisfactory to Secured Party, and such policies or certificates evidencing
the same shall be furnished to Secured  Party.  All policies of insurance  shall
provide  for  written  notice  to  Secured  Party  at  least  10 days  prior  to
cancellation. Risk of loss or damage is Debtor's to the extent of any deficiency
in any  effective  insurance  coverage.  Secured  Party  is  appointed  Debtor's
attorney-in-fact  to collect any return or unearned  premiums or the proceeds of
such insurance and to endorse any draft or check payable to Debtor therefor.

         4.4      MAINTENANCE.  Debtor shall keep and maintain the Collateral in
good  condition,  reasonable  wear and tear excepted.

obtain, preserve,  perfect, defend, and enforce this Security Interest,  collect
the Indebtedness,  and preserve,  defend,  enforce,  and collect the Collateral,
including but not limited to taxes,  assessments,  insurance premiums,  repairs,
reasonable  attorney's fees and legal expenses,  feed, rent,  storage costs, and
expenses  of  sales.  Whether  Collateral  is  or  is  not  in  Secured  Party's
possession,  and without any  obligation to do so and without  waiving  Debtor's
default for failure to make any such  payment,  Secured  Party at its option may
pay any such costs and expenses,  discharge encumbrances on the Collateral,  and
pay for  insurance  of  Collateral,  and  such  payment  shall  be a part of the
Indebtedness.  Debtor agrees to reimburse  Secured Party on demand for any costs
so incurred.

         4.6 INFORMATION AND INSPECTION.  Debtor shall (i) furnish Secured Party
any financial statements of Debtor or reports to Debtor by accountants or others
pertaining to Debtor's  business as soon as available,  and any information with
respect to the  Collateral  reasonably  requested by Secured  Party;  (ii) allow
Secured Party to inspect the  Collateral,  at any  reasonable  time and wherever
located,  and to inspect and copy, or furnish  Secured Party with copies of, all
records relating to the Collateral and the  Indebtedness;  (iii) furnish Secured
Party such  information  as Secured  Party may  reasonably  request to  identify
inventory,  accounts, and general intangibles in Collateral,  at the time and in
the form  requested by Secured  Party;  and (iv) deliver upon request to Secured
Party  shipping  and  delivery  receipts  evidencing  the  shipment of goods and
invoices   evidencing  the  receipt  of,  and  the  payment  for,  inventory  in
Collateral.

         4.7  ADDITIONAL  DOCUMENTS.  Debtor shall sign any papers  furnished by
Secured Party which are necessary in the reasonable judgment of Secured Party to
obtain,  maintain, and perfect the Security Interest and to enable Secured Party
to comply  with the  Federal  Assignment  of Claims Act or any other  federal or
state law in order to obtain or perfect Secured  Party's  interest in collateral
or to obtain proceeds of collateral.

         4.8 PARTIES LIABLE ON COLLATERAL. Debtor will preserve the liability of
all  obligors on any  Collateral,  will  preserve  the  priority of all security
therefor,  and will deliver to Secured Party the original  certificates of title
on all motor vehicles  included in the  Collateral.  Secured Party shall have no
duty to preserve  such  liability or  security,  but may do so at the expense of
Debtor, without waiving Debtor's default.

         4.9 MODIFICATION OF COLLATERAL.  Without the written consent of Secured
Party, which consent shall not be unreasonably withheld,  Debtor shall not agree
to any  modification  of any of the terms of any  accounts,  contracts,  chattel
paper, general intangibles, or instruments constituting part of the Collateral.

         4.10 RIGHT OF SECURED PARTY TO NOTIFY  DEBTORS.  During the continuance
of an Event of Default under this  Agreement,  Secured Party may notify  persons
obligated  on any  Collateral  to make  payments  directly to Secured  Party and
Secured Party may take control of all proceeds of any Collateral.  Until Secured
Party elects to exercise such rights,  Debtor, as agent of Secured Party,  shall
collect and enforce all payments owed on Collateral.

         4.11 DELIVERY OF RECEIPTS OF SECURED PARTY;  Rejected Goods. During the
continuance of an Event of Default under this  Agreement,  upon Secured  Party's
demand,  Debtor shall deposit,  upon receipt and in the form received,  with any
necessary  endorsement,  all payments  received as proceeds of Collateral,  in a
special  bank  account in a bank of Secured  Party's  choice over which  Secured
Party  alone shall have power of  withdrawal.  The funds in said  account  shall
secure the Indebtedness.  Secured Party is authorized to make any endorsement in
Debtor's name and behalf. Pending such deposit, Debtor shall not mingle any such
payments  with any of  Debtor's  other  funds or  property,  but will  hold them
separate and upon an express  trust for Secured  Party.  Secured  Party may from
time to time  apply the whole or any part of the  funds in the  special  account
against the  Indebtedness.  Unless Secured Party notifies Debtor in writing that
it dispenses with any one or more of the following requirements, Debtor shall:

                  (a)     inform  Secured  Party  immediately  of the  rejection
of goods,  delay in  delivery or performance, or claim made, in regard to any
Collateral;

                  (b)  keep  returned  goods   segregated  from  Debtor's  other
         property,  and hold the goods as trustee for Secured Party until it has
         paid Secured  Party the amount  loaned  against the related  account or
         chattel paper and deliver the goods on demand to Secured Party; and

                  (c) pay  Secured  Party the  unpaid  amount of any  account in
         Collateral  (i) if the account is not paid when due;  (ii) if purchaser
         rejects  the goods or  services  covered  by the  account;  or (iii) if
         Secured  Party shall at any time reject the account as  unsatisfactory.
         Secured Party may retain the account in  Collateral.  Secured Party may
         charge any deposit amount of Debtor with any such amounts.

         4.12 RECORDS OF COLLATERAL.  Debtor at all times will maintain accurate
books and records  covering the  Collateral.  Debtor  immediately  will mark all
books and records with an entry showing the absolute  assignment of all accounts
in  Collateral  to Secured  Party and Secured Party is hereby given the right to
audit the books and  records of Debtor  relating to  Collateral  at any time and
from time to time.  The amounts shown as owed to Debtor on Debtor's books and on
any assignment schedule will be the undisputed amounts owing and unpaid.  Debtor
shall  disclose  to  Secured  Party  all   agreements   modifying  any  account,
instrument, or chattel paper.

         4.13 DISPOSITION OF COLLATERAL.  If disposition of any Collateral gives
rise to an account,  chattel paper,  or  instrument,  Debtor  immediately  shall
notify Secured Party,  and upon request of Secured Party shall assign or endorse
the same to Secured  Party.  No Collateral  may be sold,  leased,  manufactured,
processed,  or otherwise  disposed of by Debtor in any manner  without the prior
written consent of Secured Party,  except inventory sold,  leased  manufactured,
processed, or consumed in the ordinary course of business.

         4.14  ACCOUNTS   RECEIVABLE.   Each  account  receivable   constituting
Collateral will represent the valid and legally enforceable  obligation of third
parties and shall not be evidenced by any  instrument or chattel  paper.  In the
event any account  shall give rise to any  instrument or chattel  paper,  Debtor
shall  immediately  endorse the same to Secured  Party and deliver all  original
such instruments and chattel paper to Secured Party.

<PAGE>

         4.15  LOCATION OF ACCOUNTS  AND  INVENTORY.  Debtor  shall give Secured
Party  written  notice  of each  office of  Debtor  in which  records  of Debtor
pertaining  to  accounts  in  Collateral  are kept,  and each  location at which
inventory  in  Collateral  is or will be  kept,  and of any  change  of any such
location.  If no such  notice is given,  all  records  of Debtor  pertaining  to
accounts  and all  inventory  are and shall be kept at  Debtor's  address  shown
above.

         4.16 NOTICE OF CHANGES. Debtor will notify Secured Party immediately of
any  material  change in the  Collateral,  of a change in Debtor's  residence or
location,  of a change in any matter  warranted or represented by Debtor in this
Agreement or furnished to Secured Party, and of any Event of Default.

         4.17 USE AND REMOVAL OF COLLATERAL.  Debtor will not use the Collateral
illegally.  Debtor will not permit any of the  Collateral to be removed from the
locations  specified herein or between  locations without the written consent of
Secured Party.

         4.18  POSSESSION OF  COLLATERAL.  If the  Collateral is chattel  paper,
documents,  instruments, or investment securities or other instruments,  Secured
Party may deliver a copy of this Agreement to the broker or seller  thereof,  or
any person in possession  thereof,  and such delivery shall constitute notice to
such person of Secured Party's  security  interest  therein and shall constitute
Debtor's  instruction to such person to deliver to Secured Party certificates or
other  evidence  of the  same as soon as  available.  Debtor  will  deliver  all
investment securities, other instruments, documents, and chattel paper which are
part  of the  Collateral  and  in  Debtor's  possession  to  the  Secured  Party
immediately,  or  if  hereafter  acquired,  immediately  following  acquisition,
appropriately  endorsed to Secured Party's order, or with appropriate,  executed
powers. Debtor waives presentment,  demand, notice of dishonor, protest, and all
other notices with respect thereto.

         4.19     CHATTEL  PAPER.  Debtor has perfected or will perfect a
security  interest by means  satisfactory to Secured Party in goods covered by
chattel paper in Collateral.

         4.20  CONSUMER   CREDIT.   If  any  Collateral  or  proceeds   includes
obligations  of third  parties to Debtor,  the  transactions  giving rise to the
Collateral  shall  conform in all  respects to the  applicable  state or federal
consumer  credit law.  DEBTOR SHALL HOLD  HARMLESS AND  INDEMNIFY  SECURED PARTY
AGAINST ANY COST,  LOSS,  OR EXPENSE  INCLUDING  ATTORNEY'S  FEES,  ARISING FROM
DEBTOR'S BREACH OF THIS COVENANT.

         4.21 CHANGE OF NAME.  Debtor  shall not change its name (or any assumed
name or other name under which Debtor does business) or its corporate  structure
unless at least  thirty (30) days prior to the  effective  date of any such name
change,  Debtor gives Secured Party written  notice of such intended name change
and the new name or any  change  in its  corporate  structure.  Debtor  will not
change its principal  place of business,  chief executive  office,  or the place
where it keeps its books and records  unless Debtor (i) shall have given Secured
Party thirty (30) days prior written notice  thereof,  and (ii) shall have taken
all action deemed  necessary or desirable by Secured Party to cause the Security
Interest  to be  and  remain  perfected  with  the  priority  required  by  this
Agreement.  Debtor shall execute all such  documents and  agreements  (including
without limitation security agreements,  financing statements, and amendments to
financing statements) as Secured Party may reasonably request in connection with
any such name change.

         4.22     NOTATION  ON TITLE  CERTIFICATES.  If  certificates  of title
are  issued  or  outstanding  with respect to any of the Collateral, Debtor will
cause the Security Interest to be properly noted therein.

         4.23 POWER OF  ATTORNEY.  Debtor  appoints  Secured  Party as  Debtor's
attorney-in-fact  with full  power in  Debtor's  name and behalf to do every act
which  Debtor is obligated  to do or may be required to

<PAGE>

do  hereunder;  however,  nothing in this section shall be construed to obligate
Secured Party to take any action hereunder.

         4.24 DEBTOR'S WAIVERS.  Except as otherwise  provided in this Agreement
or by law, Debtor waives notice of the creation,  advance, increase,  existence,
extension,   or  renewal  of,  and  of  any  indulgence  with  respect  to,  the
Indebtedness;  waives notice of intent to  accelerate,  notice of  acceleration,
notice  of intent to  demand,  presentment,  demand,  notice  of  dishonor,  and
protest;  waives  notice of the amount of the  Indebtedness  outstanding  at any
time,  notice of any change in financial  condition of any person liable for the
Indebtedness  or  any  part  thereof,  and  all  other  notices  respecting  the
Indebtedness;  and agrees that maturity of the Indebtedness and any part thereof
may be accelerated,  extended,  or renewed one or more times by Secured Party in
its discretion, without notice to Debtor.

         4.25 OTHER PARTIES AND OTHER COLLATERAL.  No renewal or extension of or
any other  indulgence with respect to the  Indebtedness or any part thereof,  no
release  of any  security,  no  release  of any  person  (including  any  maker,
endorser,  guarantor,  or  surety)  liable  on the  Indebtedness,  no  delay  in
enforcement  of payment,  and no delay or admission or lack of diligence or care
in  exercising  any  right or power  with  respect  to the  Indebtedness  or any
security  therefor or guaranty  thereof or under this  Agreement  shall in other
manner  impair or affect the rights of Secured  Party under the law,  under this
Agreement, or under any other agreement pertaining to the other security for the
Indebtedness,  before  foreclosing upon the Collateral for the purpose of paying
the  Indebtedness.  Debtor  waives any right to the  benefit of or to require or
control application of any other security or proceeds thereof, and Debtor agrees
that Secured  Party shall have no duty or  obligation  to Debtor to apply to the
Indebtedness any such other security or proceeds thereof.

         4.26  RELEASE OF FILINGS.  On or before  July 15,  1999,  Debtor  shall
ensure  that a release of all filings (in any public  office)  which  purport to
provide  notice of liens  and/or  obligations  of or against  Debtor or Debtor's
assets,  other than those  listed on Exhibit  "B",  is filed in the  appropriate
public office.

                                    ARTICLE V

                       RIGHTS AND POWERS OF SECURED PARTY

         5.1 GENERAL.  Secured Party before default without  liability to Debtor
may: obtain from any person  information  regarding Debtor or Debtor's business,
which  information any such person also may furnish without liability to Debtor;
endorse as  Debtor's  agent any  instruments,  documents,  or  chattel  paper in
Collateral or  representing  proceeds of  Collateral;  contact  account  debtors
directly to verify  information  furnished by Debtor;  release Collateral in its
possession to any Debtor temporarily or otherwise;  reject as unsatisfactory any
property  hereafter offered by Debtor as Collateral;  set standards from time to
time to govern what may be used as  after-acquired  collateral;  and at any time
transfer any of the Collateral or evidence  thereof into its own name or that of
its  nominee.  Secured  Party,  during  the  continuance  of an Event of Default
without liability to Debtor, may:

                  (a)      require Debtor to give possession or control of any
                          Collateral to Secured Party;

                  (b)      take control of proceeds;

                  (c)      require additional collateral;

                  (d) take control of funds generated by the Collateral, such as
         cash dividends,  interest, and proceeds or refunds from insurance,  and
         use same to reduce any part of the  Indebtedness and exercise all other
         rights which an owner of such Collateral may exercise, except the right
         to vote or dispose of Collateral before an Event of Default; and

<PAGE>

                  (e) demand,  collect,  convert,  redeem,  receipt for, settle,
         compromise,  adjust, sue for, foreclose, or realize upon Collateral, in
         its own name or in the name of Debtor,  as Secured  Party may determine
         in its sole and absolute discretion,

         Secured Party shall not be liable for failure to collect any account or
instrument,  or for any act or omission on the part of the  Secured  Party,  its
officers, agents, or employees,  except willful misconduct. The foregoing rights
and powers of Secured  Party will be in addition to, and not a limitation  upon,
any  rights  and  powers  of  Secured  Party  given  by law,  elsewhere  in this
Agreement,  or otherwise. If Debtor fails to maintain any required insurance, to
the extent  permitted by applicable  law Secured Party may (but is not obligated
to)  purchase  single  interest  insurance  coverage  for the  Collateral  which
insurance may at Secured  Party's  option (i) protect only Secured Party and not
provide any  remuneration  or protection for Debtor  directly,  and (ii) provide
coverage only after the  Indebtedness  has been declared due as herein provided.
The premiums for any such  insurance  purchased by Secured Party shall be a part
of the Indebtedness and shall bear interest as provided in Section 1.2(c) above.

                                   ARTICLE VI

                                     DEFAULT

         6.1      Events of  Default.  The  following  are events of  default
under this  Agreement  ("Events  of Default"):

                  (a)      default  in the timely  payment of any part of the
         Indebtedness  or in  performance  or observance of the terms and
         conditions herein or the Loan Agreement between Debtor and Secured
         Party;

                  (b)  any  warranty,   representation,  or  statement  made  or
         furnished to Secured  Party by Debtor  proves to have been false in any
         material respect when made or furnished;

                  (c)      acceleration of the maturity of debt of Debtor to any
         other person;

                  (d)      loss, theft,  destruction which is not covered by
         Debtor's insurance,  of any Collateral in violation hereof, or
         substantial damage to any Collateral;

                  (e) death, incapacity,  dissolution, merger, or consolidation,
         termination of existence,  insolvency or business  failure of Debtor or
         any person liable on the Indebtedness;  commencement of proceedings for
         the appointment of a receiver for any property of Debtor;  commencement
         of any proceeding  under any bankruptcy or insolvency law by or against
         Debtor (or any corporate  action shall be taken to effect same), or any
         partnership  of which Debtor is a partner,  or by or against any person
         liable  upon the  Indebtedness  or any part  thereof,  or  liable  upon
         Collateral; or

                  (f)      levy on,  seizure,  or  attachment  of any  property
         of Debtor, or a judgment against Debtor, in each case in excess of
         $10,000.

         6.2 REMEDIES OF SECURED  PARTY UPON  DEFAULT.  When an Event of Default
occurs, and at any time thereafter so long as the Event of Default is not cured,
Secured  Party  without  notice or  demand  (except  as  otherwise  required  by
statute),  may declare the Indebtedness in whole or part immediately due and may
enforce  payment of the same and exercise any rights under the Texas UCC, rights
and remedies of Secured Party under this Agreement, or otherwise.  Secured Party
may require  Debtor to assemble the  Collateral and make it available to Secured
Party at a place which is reasonably  convenient  to both  parties.  Expenses of
retaking, holding, preparing for sale, selling, leasing, or the like shall

<PAGE>

include Secured Party's reasonable  attorney's fees and legal expenses.  Secured
Party  shall be  entitled  to  immediate  possession  of all books  and  records
evidencing  any accounts or general  intangibles  or pertaining to chattel paper
covered  by this  Agreement  and  shall  have the  authority  to enter  upon any
premises  upon which any of the same,  or any  Collateral,  may be situated  and
remove the same  therefrom  without  liability.  Secured Party may surrender any
insurance  policies in  Collateral  and receive the  unearned  premium  thereon.
Debtor shall be entitled to any surplus  after payment of the  Indebtedness  and
shall be  liable  to  Secured  Party  for any  deficiency.  The  process  of any
disposition after default available to satisfy the Indebtedness shall be applied
to the  Indebtedness  in such order and in such  manner as Secured  Party in its
discretion  shall  decide.  If, in the  opinion of Secured  Party,  there is any
question that a public sale or  distribution  of any Collateral will violate any
state or federal securities law, Secured Party (i) may offer and sell securities
privately to purchasers who will agree to take them for investment  purposes and
not with a view to distribution  and who will agree to imposition of restrictive
legends on the  certificates  representing  the security,  or (ii) may sell such
securities in an intrastate  offering  under Section  3(a)(11) of the Securities
Act of 1933,  and no sale so made in good faith by Secured Party shall be deemed
to be not "commercially reasonable" because so made.

                                   ARTICLE VII

                                     GENERAL

         7.1 PARTIES BOUND.  Secured Party's rights under this Agreement and the
Security Interest shall inure to the benefits of its successors and assigns, and
in the event of any  assignment  or transfer of any of the  Indebtedness  or the
Collateral,  Secured  Party  thereafter  shall  be  fully  discharged  from  any
responsibility  with respect to the Collateral so assigned or  transferred,  but
Secured  Party shall  retain all rights and powers  hereby given with respect to
any of the  Indebtedness  or  Collateral  not so  assigned or  transferred.  All
representations, warranties, and agreements of Debtor if more than one are joint
and several, and all shall be binding upon the personal representatives,  heirs,
successors, and assigns of Debtor.

         7.2 WAIVER.  No delay of Secured Party in exercising any power or right
shall operate as a waiver thereof;  nor shall any single or partial  exercise of
any power or right preclude other or further exercise thereof or the exercise of
any other power or right.  No waiver by Secured Party of any right  hereunder of
any default by Debtor shall be binding upon Secured Party unless in writing, and
no failure by Secured  Party to exercise any power or right  hereunder or waiver
of any  default  by Debtor  shall  operate  as a waiver of any other or  further
exercise of such right or power of any further default.

         7.3 AGREEMENT CONTINUING.  This Agreement shall constitute a continuing
agreement,  applying to all future as well as existing transactions,  whether or
not of the  character  contemplated  at the date of this  Agreement,  and if all
transactions between Secured Party and Debtor shall be closed at any time, shall
be equally  applicable to any new  transactions  thereafter.  Provisions of this
Agreement,  unless  by their  terms  exclusive,  shall be in  addition  to other
agreements between the parties.

         7.4 DEFINITIONS. Unless the context indicates otherwise, definitions in
the  Texas  UCC  apply to words  and  phrases  in this  Agreement;  if Texas UCC
definitions conflict, Chapter 9 definitions apply.

         7.5 NOTICE.  Notices  required herein or under  applicable law shall be
deemed  reasonable if mailed postage  prepaid at least 5 days before the related
action (or if the Texas UCC  elsewhere  specifies a longer  period,  such longer
period) to the address shown above.

         7.6  INTEREST.  No  agreement  relating  to the  Indebtedness  shall be
construed to be a contract for or to authorize charging or receiving, or require
the  payment or permit the  collection  of,  interest  at a rate

<PAGE>

or in an  amount  above  that  authorized  by law.  Interest  payable  under any
agreement  above that  authorized by law shall be reduced  automatically  to the
highest amount permitted by law.

         7.7  MODIFICATIONS.  No  provision  hereof shall be modified or limited
except by a written agreement  expressly  referring hereto and to the provisions
so modified or limited and signed by Debtor and Secured Party,  nor by course of
conduct, usage of trade, or by the law merchant.

         7.8      SEVERABILITY.  The unenforceability  of any provision  of this
Agreement shall not affect the enforceability or validity of any other
provision.

         7.9 GENDER AND NUMBER.  Where appropriate,  the use of one gender shall
be construed to include the others or any of them; and the singular number shall
be construed to include the plural, and vice versa.

         7.10  Applicable  Law and  Venue.  THIS  AGREEMENT  SHALL BE  CONSTRUED
ACCORDING TO THE LAWS OF THE STATE OF TEXAS AND THE LAWS OF THE UNITED STATES OF
AMERICA  APPLICABLE TO TRANSACTIONS  IN THE STATE OF TEXAS.  Except at otherwise
stated,  this  Agreement  and  the  Security  Interest  shall  be  construed  in
accordance  with the Texas Uniform  Commercial Code [Texas Business and Commerce
Code Sec. 1.01, et seq. ("Texas UCC")].  This Agreement is performable by Debtor
in the county of Secured Party's address set out above.

         7.11     FINANCING  STATEMENT.  A carbon,  photographic,  or other
reproduction of this security agreement
or any financing statement covering the Collateral shall be sufficient as a
financing statement.

         7.12  LIMITATIONS  OF LAW. If any law prohibits or limits any charge or
expense  provided  for in this  Agreement  in  connection  with any loan secured
hereby,  such charge or expense will not be made or incurred in connection  with
such loan beyond the limits permitted by such law.

         EXECUTED this 16th day of June, 1999.

         THIS SUBORINATION  AGREEMENT is made as of the 16th day of June, 1999,

                              W I T N E S S E T H:

WHEREAS, the Creditor has extended certain loans and financial accommodations to
APS Consulting,  Inc., a Texas  corporation (the "Company")  pursuant to certain
refinancing  agreements,  loan agreements and instruments executed in connection
therewith (collectively, the "Creditor Agreements"); and

         WHEREAS, the Company is indebted to the Creditor, which indebtedness is
secured  by  certain  security  interests  in the  assets  of the  Company  (the
"Creditor Collateral") pursuant to the Creditor Agreements; and

         WHEREAS,  pursuant to the terms of that certain  Loan  Agreement by and
between the Company and APSC,  and that certain  Promissory  Note by and between
the Company and APSC, both dated as of June 16, 1999,  (collectively,  the "Loan
Agreement"), APSC may, from time to time, advance funds to the Company; and

         WHEREAS,  pursuant to the terms of that certain  Security  Agreement by
and  between the Company  and APSC,  of even date with the Loan  Agreement  (the
"APSC Security Agreement"), APSC desires to obtain a security interest in all of
the assets of the Company (the "APSC Collateral") that is senior to the security
interests held by Creditor; and

         WHEREAS,  the Creditor  and APSC wish to enter into certain  agreements
with respect to the administration of their respective security interests in the
Creditor Collateral and the APSC Collateral;

         NOW, THEREFORE, the parties hereto agree as follows:

         1.       The Creditor  consents to the  execution  and delivery by the
Company of the Loan  Agreement  and the APSC Security Agreement.

         2.  Notwithstanding  any  provisions  to the  contrary in the  Creditor
Agreements or the APSC Security  Agreement,  the respective orders or priorities
which would  ordinarily  result from the time of granting and the time and place
of  perfection  of the  respective  security  interests of the Creditor and APSC
under the Uniform Commercial Code as in effect in any jurisdiction or otherwise:

                  (a)      the  security  interest  of APSC in all the assets of
         the  Company  shall be superior to and have priority over the security
         interest of the Creditor in the APSC Collateral; and

<PAGE>

                  (b)      the  security  interest of the Creditor in the
         Creditor  Collateral  shall be junior to and be subordinate to the
         security interest of APSC.

         3. APSC agrees to give the Creditor notice of any default, acceleration
or  enforcement  of its  security  interest  under the Loan  Agreement,  and the
Creditor  agrees  to  give  to  APSC  notice  of any  default,  acceleration  or
enforcement of its security interest under the Creditor Agreements, in each case
prior to or concurrently with the giving of such notice to the Company.

         4. At such time as the Company's  obligations to the Creditor  pursuant
to the Creditor  Agreements  shall have been paid and  discharged  in full,  the
Creditor will assign its security interest in all of the Creditor  Collateral to
APSC and deliver to APSC all instruments and documents  included in the Creditor
Collateral  and in the  possession  of the  Creditor.  The Company  consents and
agrees to such transfer and agrees that any such instruments and documents shall
thereafter  be held by APSC  subject  to the  provisions  of the  APSC  Security
Agreement.  The cost and expense of effectuating  such assignment shall be borne
by the Company.

         5. The  Creditor  shall not  assign or  transfer  any claim  against or
interest  of any  kind in the  Creditor  Collateral  to any  person  while  this
Agreement  remains in effect  unless  such  person  shall  execute an  agreement
reasonably satisfactory to APSC to be bound by this Agreement.

         6. APSC shall not assign or transfer  any claim  against or interest of
any kind in the APSC  Collateral to any person while this  Agreement  remains in
effect unless such person shall execute an agreement reasonably  satisfactory to
the Creditor to be bound by this Agreement.

remedies under the Creditor Agreements and under the Loan Agreement and Security
Agreement,  the  Creditor  and APSC  will  cooperate  in the  exercise  of their

<PAGE>

MAXIMUM PRINCIPAL AMOUNT:  One Million Dollars and No/100 Dollars ($1,000,000)

INTEREST RATE:  Twelve Percent (12.0%)

PAYMENT  TERMS:  Interest  under  this  Note is due and  payable  semi-annually,
beginning October 1, 1999, and continuing regularly and semi-annually thereafter
on or before the first day of October and April of each year, until the Maturity
Date (as hereinafter  defined),  when the outstanding  principal balance and all
accrued  interest  shall be due and payable in full (or  converted  into capital
stock of Borrower pursuant to Section 3). The Maturity Date shall be the earlier
to occur of April  30,  2000 or the date of  closing  of any  Qualifying  Equity
Financing  (as  hereinafter  defined);  provided  that  if no  Qualified  Equity
Financing has previously occurred,  and if Borrower is not in default hereunder,

but  only  by  giving  Lender   written  notice  and  paying  Lender  a  $10,000
non-refundable  extension  fee  prior to  April 1,  2000.  Any  payment  will be
credited first to expense reimbursements due hereunder, then to accrued interest
and then to the reduction of principal.

REVOLVING  LINE OF  CREDIT:  This Note  evidences  a  revolving  line of credit.
Subject to the terms and conditions  contained herein, all or any portion of the
Maximum  Principal  Amount  of this  Note may be  borrowed,  paid,  repaid,  and
reborrowed,  from time to time prior to the Maturity  Date.  Each  borrowing and
repayment  hereunder will be (i) endorsed on an attachment to this Note, or (ii)
entered  in the books and  records of  Lender.  The books and  records of Lender
shall be prima facie evidence of all sums due Lender. If an Event of Default, or
breach or threatened breach by Borrower,  exists or has occurred under this Note
or any other contract, agreement, document, instrument or certificate executed,

<PAGE>

alone or together with third parties, by Borrower and Lender (or by Borrower for
the benefit of Lender),  then Lender  shall be under no  obligation  to make any
advance under this Note.

1.       INTEREST PROVISIONS:

         (a)  RATE:  The  principal  balance  of  this  Note  from  time to time
remaining  unpaid prior to maturity shall bear interest at the Interest Rate per
annum stated  above.  On each  interest  payment date and on the Maturity  Date,
interest  shall be  calculated  on the  amount of each  advance  of the  Maximum
Principal Amount of this Note, from the date of each such advance.

         (b) MAXIMUM LAWFUL  INTEREST:  The term "Maximum Lawful Rate" means the
maximum rate of interest and the term "Maximum  Lawful Amount" means the maximum
amount of interest that is permissible under applicable state or federal law for
the type of loan evidenced by this Note. If the Maximum Lawful Rate is increased
by statute or other  governmental  action  subsequent  to the date of this Note,
then the new  Maximum  Lawful  Rate  shall be  applicable  to this Note from the
effective date thereof, unless otherwise prohibited by applicable law.

         (c)  SPREADING OF  INTEREST:  Because of the  possibility  of irregular
periodic  balances of principal or premature  payment,  the total  interest that
will accrue  under this Note cannot be  determined  in advance.  Lender does not
intend to contract for, charge,  or receive more than the Maximum Lawful Rate or
Maximum  Lawful  Amount  permitted  by  applicable  state or federal law, and to
prevent  such an  occurrence  Lender  and  Borrower  agree  that all  amounts of
interest,  whenever contracted for, charged, or received by Lender, with respect
to the loan of money  evidenced  by this  Note,  shall be spread,  prorated,  or
allocated over the full period of time this Note is unpaid, including the period
of any renewal or extension of this Note.  If demand for payment of this Note is
made by Lender prior to the full stated term,

<PAGE>

the total amount of interest contracted for, charged, or received to the time of
such demand  shall be spread,  prorated,  or  allocated  along with any interest
thereafter  accruing  over the full  period of time  that  this Note  thereafter
remains  unpaid for the  purpose of  determining  if such  interest  exceeds the
Maximum Lawful Amount.

         (d) EXCESS INTEREST: At maturity (whether by acceleration or otherwise)
or on earlier final payment of this Note,  Lender shall compute the total amount
of interest  that has been  contracted  for,  charged,  or received by Lender or
payable by  Borrower  under this Note and  compare  such  amount to the  Maximum
Lawful  Amount  that could have been  contracted  for,  charged,  or received by
Lender. If such computation  reflects that the total amount of interest that has
been  contracted  for,  charged,  or  received  by Lender or payable by Borrower
exceeds the Maximum  Lawful  Amount,  then Lender shall apply such excess to the
reduction of the  principal  balance and not to the payment of  interest;  or if
such excess interest exceeds the unpaid principal balance,  such excess shall be
refunded to  Borrower.  This  provision  concerning  the  crediting or refund of
excess  interest  shall control and take  precedence  over all other  agreements
between  Borrower  and  Lender so that  under no  circumstances  shall the total
interest  contracted  for,  charged,  or received  by Lender  exceed the Maximum
Lawful Amount.

         (e) INTEREST AFTER DEFAULT:  At Lender's  option,  the unpaid principal
balance  shall  bear  interest  after  maturity   (whether  by  acceleration  or
otherwise) at the "Default  Interest Rate." The Default  Interest Rate shall be,
at Lender's option,  (i) the Maximum Lawful Rate, if such Maximum Lawful Rate is
established  by  applicable  law; or (ii) the Interest  Rate stated on the first
page of this Note plus three (3) percentage points, if no Maximum Lawful Rate is
established  by applicable  law; or (iii) eighteen  percent (18%) per annum;  or
(iv) such lesser rate of interest as Lender in its sole discretion may choose to
charge;  but never  more than the  Maximum  Lawful  Rate or at a rate that would
cause the total  interest  contracted  for,  charged,  or  received by Lender to
exceed the Maximum Lawful Amount.

<PAGE>

         (f)  Daily  Computation  of  Interest:   To  the  extent  permitted  by
applicable  law,  Lender at its option will calculate the per diem interest rate
or amount  based on the  actual  number of days in the year (365 or 366,  as the
case may be), and charge that per diem  interest  rate or amount each day. In no
event shall  Lender  compute the interest in a manner that would cause Lender to
contract for,  charge,  or receive interest that would exceed the Maximum Lawful
Rate or the Maximum Lawful Amount.

2.       ADVANCES:

         (a)  REVOLVING  LINE OF  CREDIT.  Subject to and in  reliance  upon the
terms, conditions,  representations and warranties hereinafter set forth, Lender
agrees to make advances (an  "Advance") to Borrower from time to time during the
period from the date hereof to and  including  the Maturity Date in an aggregate
amount not to exceed the Maximum Principal  Amount.  Each Advance must be in the
minimum  amount of $10,000 or in a higher  integral  multiple of $10,000.  Funds
borrowed and repaid may be reborrowed,  so long as all  conditions  precedent to
Advances are met.  The purpose of the  Advances is to provide  funds to Borrower
for working capital and for other general business purposes of Borrower.

         (b) MAKING  ADVANCES.  Each  Advance  shall be made within two business
days of written notice (or telephonic notice confirmed in writing) given by noon
(Austin,  Texas  time)  on a  business  day of  Lender  by  Borrower  to  Lender
specifying  the amount and date thereof (which may be the same business day) and
if sent by wired  funds,  at Lender's  option,  the wiring  instructions  of the
deposit account of Borrower to which such Advance is to be deposited.

         (c) PAYMENTS AND  COMPUTATIONS.  Borrower shall make each payment under
this Note on the day when due in lawful money of the United States of America to
Lender at Lender's Address for

<PAGE>

payment in same day funds or other payment method
acceptable  to Lender.  All  repayments  of  principal on the Note shall be in a
minimum amount of $10,000, or a higher integral multiple of $10,000.

         (d) CONDITION PRECEDENT TO INITIAL ADVANCE. The obligation of Lender to
make its initial Advance is subject to the condition precedent that Lender shall
have received on or before the day of such Advance the  following,  each in form
and substance  satisfactory to Lender and properly executed by Borrower or other
appropriate  parties:  (i) the Note duly  executed by Borrower;  (ii) such other
documents,  opinions,  certificates  and  evidences  as  Lender  may  reasonably
request;  and (iii) reimbursement in full for all costs and expenses (including,
without limitation, legal fees and expenses) incurred by Lender in entering into
this lending arrangement.

         (e) CONDITIONS PRECEDENT TO EACH ADVANCE. In addition to the conditions
precedent  stated  elsewhere  herein,  Lender shall not be obligated to make any
Advance unless: (i) the representations and warranties  contained in paragraph 3
are true and  correct  in all  material  respects  on and as of the date of such
Advance as though made on and as of such date;  (ii) on the date of the Advance,
no Event of  Default,  and no event  which,  with the lapse of time or notice or
both,  could become an Event of Default,  and no breach or threatened  breach by
Borrower,  has  occurred  under  this  Note or any  other  contract,  agreement,
document,  instrument  or  certificate  executed by  Borrower  and Lender (or by
Borrower  for the  benefit of  Lender);  (iii) there shall have been no material
adverse  change,  as determined  by Lender in its  reasonable  judgment,  in the
financial  condition  or  business of  Borrower;  (iv)  Borrower  shall not have
previously  provided notice to Lender of a Qualifying Equity Financing  pursuant
to subsection  3(c);  and (v) Lender shall have  received such other  approvals,
opinions, documents,  certificates or evidences as Lender may reasonably request
(in form and substance reasonably  satisfactory to Lender).  Each request for an
Advance shall be deemed a representation by Borrower that the conditions of this
subsection have been met.

3.       CONVERSION:

         (a) QUALIFYING EQUITY FINANCING.  A "Qualifying Equity Financing" shall
mean any equity financing or series of related equity  financings,  occurring on
or before the Maturity Date, in which  Borrower  sells equity  securities to any
one or more parties (including,  without limitation,  Lender and any of Lender's
affiliates) and obtains net proceeds  (excluding  conversion of this Note) in an
amount  not  less  than  One  Million  Two  Hundred   Fifty   Thousand   Dollars
($1,250,000).

         (b) CONVERSION.  At the closing of any Qualifying Equity Financing, the
entire outstanding balance of this Note (including  principal,  interest and any
other amounts due  hereunder,  the  "Outstanding  Balance")  shall,  at the sole
discretion  of  Borrower,  be  either  (i)  paid in full  by  wire  transfer  of
immediately  available  funds or (ii)  converted  into capital stock of Borrower
using a conversion price of $2.00 per share (the "Conversion Price"). If, at the
maturity date,  including  extensions  thereof,  the Outstanding Balance has not
been paid in full, the Borrower shall have 90 days in which to make payment. If,
at the end of the 90-day period, the Lender has not received full payment of the
Outstanding  Balance,   then  the  Lender  has  the  option  of  converting  the
Outstanding Balance into capital stock of Borrower at the Conversion Price.

         (c) NOTICE. Borrower shall provide the Bank and Lender with at least 30
days prior written  notice of the closing of any  Qualifying  Equity  Financing,
delivered to the address for such party last shown on the records of Borrower or
given by such party to Borrower for the purpose of notice.

         (d) ISSUANCE OF SHARES. If this Note is converted into capital stock of
Borrower  pursuant to this  subsection,  Borrower shall prior to or concurrently
with such  conversion,  deliver  to Lender a written

<PAGE>

statement  specifying the amount of the  Outstanding  Balance,  the number and a
description  of shares of capital stock  issuable upon such  conversion  and the
date of such  conversion.  As promptly  as  practicable  after such  conversion,
Borrower  will, at its expense,  issue and deliver to Lender,  upon surrender of
this Note,  a  certificate  or  certificates  for the  number of full  shares of
capital stock issuable upon such conversion.

         (e)      NO FURTHER ADVANCES.  After the occurrence of a Qualifying
Equity Financing,  Lender shall have no obligation to make any advance of any
kind to Borrower under this Note.

         (f) ADJUSTMENTS UPON DILUTION. The number of shares of capital stock of
Borrower to be received upon conversion of the Outstanding  Balance hereunder by
Lender (the "Stock") shall be subject to adjustment as follows: (i) in the event
there is a subdivision or combination of the outstanding  shares of Stock into a
larger or  smaller  number of shares,  the number of shares of Stock  receivable
upon conversion of the Outstanding  Balance shall be increased or reduced in the
same proportion as the increase or decrease in the outstanding  shares of Stock;
(ii) if the Company  declares a dividend on Stock payable in Stock or securities
convertible into Stock, the number of shares of Stock receivable upon conversion
of the  Outstanding  Balance  shall  be  increased,  as of the  record  date for
determining  which holders of Stock shall be entitled to receive such  dividend,
in proportion to the increase in the number of outstanding  shares of Stock as a
result of such dividend.  Whenever the number of shares of Stock receivable upon
conversion  is  adjusted  as herein  provided,  the  Conversion  Price  shall be
adjusted by multiplying the applicable  Conversion  Price  immediately  prior to
such  adjustment  by a fraction,  the  numerator of which shall be the number of
shares of Stock receivable upon conversion  immediately prior to such adjustment
and the  denominator of which shall be the number of shares of Stock  receivable
immediately after such adjustment.

         lapse  of any  cure  period  expressly  set  forth  in  such  contract,
         agreement, instrument or certificate; or

                  (iv)   Borrower or any guarantor files for bankruptcy, becomes

failure to pursue some remedy,  acceptance  of late  payments,  or acceptance of
partial  payment  by  Lender,  before  or  after  the  Maturity  Date,  does not
constitute a waiver by Lender of its  subsequent  right to strictly  enforce the
collection of this Note according to its terms.

         (d)      OTHER REMEDIES NOT REQUIRED:  Lender shall not be required to
first file suit,  exhaust all remedies,  or enforce its rights against any
security in order to enforce payment of this Note.

         (f) RIGHT OF SET-OFF. Borrower hereby authorizes Lender, to the maximum
extent permitted under and in accordance with applicable laws, at any time after

guarantor, or to any surety or endorser of this Note, or to any other person.

         Notwithstanding  any other provision of this Note,  Borrower and Lender
each agree that neither  this Note nor any amount owed under this Note  (whether

between Borrower and Lender,  dated January 1, 1998 (the "Security  Agreement").
Except as expressly stated in the foregoing sentence,  neither this Note nor any
of the  provisions  of this Note shall  modify,  amend,  supplement or limit the

beginning October 1, 1999, and continuing regularly and semi-annually thereafter
on or before the first day of October and April of each year, until the Maturity
Date (as hereinafter  defined),  when the outstanding  principal balance and all

stock of Borrower pursuant to Section 3). The Maturity Date shall be the earlier
to occur of April  30,  2000 or the date of  closing  of any  Qualifying  Equity
Financing  (as  hereinafter  defined);  provided  that  if no  Qualified  Equity
Financing has previously occurred,  and if Borrower is not in default hereunder,

<PAGE>

REVOLVING  LINE OF  CREDIT:  This Note  evidences  a  revolving  line of credit.
Subject to the terms and conditions  contained herein, all or any portion of the
Maximum  Principal  Amount  of this  Note may be  borrowed,  paid,  repaid,  and
reborrowed,  from time to time prior to the Maturity  Date.  Each  borrowing and
repayment  hereunder will be (i) endorsed on an attachment to this Note, or (ii)
entered  in the books and  records of  Lender.  The books and  records of Lender
shall be prima facie evidence of all sums due Lender. If an Event of Default, or
breach or threatened breach by Borrower,  exists or has occurred under this Note
or any other contract, agreement,  document, instrument or certificate executed,
alone or together with third parties, by Borrower and Lender (or by Borrower for
the benefit of Lender),  then Lender  shall be under no  obligation  to make any
advance under this Note.

1.       INTEREST PROVISIONS:

         (a)  Rate:  The  principal  balance  of  this  Note  from  time to time
remaining  unpaid prior to maturity shall bear interest at the Interest Rate per
annum stated  above.  On each  interest  payment date and on the Maturity  Date,
interest  shall be  calculated  on the  amount of each  advance  of the  Maximum
Principal Amount of this Note, from the date of each such advance.

         (b) Maximum Lawful  Interest:  The term "Maximum Lawful Rate" means the
maximum rate of interest and the term "Maximum  Lawful Amount" means the maximum
amount of interest that is permissible under applicable state or federal law for
the type of loan evidenced by this Note. If the Maximum Lawful Rate is increased
by statute or other  governmental  action  subsequent  to the date of this Note,
then the new  Maximum  Lawful  Rate  shall be  applicable  to this Note from the
effective date thereof, unless otherwise prohibited by applicable law.

<PAGE>

         (c)  Spreading of  Interest:  Because of the  possibility  of irregular
periodic  balances of principal or premature  payment,  the total  interest that
will accrue  under this Note cannot be  determined  in advance.  Lender does not
intend to contract for, charge,  or receive more than the Maximum Lawful Rate or
Maximum  Lawful  Amount  permitted  by  applicable  state or federal law, and to
prevent  such an  occurrence  Lender  and  Borrower  agree  that all  amounts of
interest,  whenever contracted for, charged, or received by Lender, with respect
to the loan of money  evidenced  by this  Note,  shall be spread,  prorated,  or
allocated over the full period of time this Note is unpaid, including the period
of any renewal or extension of this Note.  If demand for payment of this Note is
made by Lender  prior to the full  stated  term,  the total  amount of  interest
contracted for, charged, or received to the time of such demand shall be spread,
prorated, or allocated along with any interest thereafter accruing over the full
period of time that this Note  thereafter  remains  unpaid  for the  purpose  of
determining if such interest exceeds the Maximum Lawful Amount.

         (d) Excess Interest: At maturity (whether by acceleration or otherwise)
or on earlier final payment of this Note,  Lender shall compute the total amount
of interest  that has been  contracted  for,  charged,  or received by Lender or
payable by  Borrower  under this Note and  compare  such  amount to the  Maximum
Lawful  Amount  that could have been  contracted  for,  charged,  or received by
Lender. If such computation  reflects that the total amount of interest that has
been  contracted  for,  charged,  or  received  by Lender or payable by Borrower
exceeds the Maximum  Lawful  Amount,  then Lender shall apply such excess to the
reduction of the  principal  balance and not to the payment of  interest;  or if
such excess interest exceeds the unpaid principal balance,  such excess shall be
refunded to  Borrower.  This  provision  concerning  the  crediting or refund of
excess  interest  shall control and take  precedence  over all other  agreements
between  Borrower  and  Lender so that  under no  circumstances  shall the total
interest  contracted  for,  charged,  or received  by Lender  exceed the Maximum
Lawful Amount.

<PAGE>

         (e) Interest After Default:  At Lender's  option,  the unpaid principal
balance  shall  bear  interest  after  maturity   (whether  by  acceleration  or
otherwise) at the "Default  Interest Rate." The Default  Interest Rate shall be,
at Lender's option,  (i) the Maximum Lawful Rate, if such Maximum Lawful Rate is
established  by  applicable  law; or (ii) the Interest  Rate stated on the first
page of this Note plus three (3) percentage points, if no Maximum Lawful Rate is
established  by applicable  law; or (iii) eighteen  percent (18%) per annum;  or
(iv) such lesser rate of interest as Lender in its sole discretion may choose to
charge;  but never  more than the  Maximum  Lawful  Rate or at a rate that would
cause the total  interest  contracted  for,  charged,  or  received by Lender to
exceed the Maximum Lawful Amount.

         (f)  Daily  Computation  of  Interest:   To  the  extent  permitted  by
applicable  law,  Lender at its option will calculate the per diem interest rate
or amount  based on the  actual  number of days in the year (365 or 366,  as the
case may be), and charge that per diem  interest  rate or amount each day. In no
event shall  Lender  compute the interest in a manner that would cause Lender to
contract for,  charge,  or receive interest that would exceed the Maximum Lawful
Rate or the Maximum Lawful Amount.

2.       ADVANCES:

         (a)  Revolving  Line of  Credit.  Subject to and in  reliance  upon the
terms, conditions,  representations and warranties hereinafter set forth, Lender
agrees to make advances (an  "Advance") to Borrower from time to time during the
period from the date hereof to and  including  the Maturity Date in an aggregate
amount not to exceed the Maximum Principal  Amount.  Each Advance must be in the
minimum  amount of $10,000 or in a higher  integral  multiple of $10,000.  Funds
borrowed and repaid may be reborrowed,  so long as all  conditions  precedent to
Advances are met.  The purpose of the  Advances is to provide  funds to Borrower
for working capital and for other general business purposes of Borrower.

<PAGE>

         (b) Making  Advances.  Each  Advance  shall be made within two business
days of written notice (or telephonic notice confirmed in writing) given by noon
(Austin,  Texas  time)  on a  business  day of  Lender  by  Borrower  to  Lender
specifying  the amount and date thereof (which may be the same business day) and
if sent by wired  funds,  at Lender's  option,  the wiring  instructions  of the
deposit account of Borrower to which such Advance is to be deposited.

         (c) Payments and  Computations.  Borrower shall make each payment under
this Note on the day when due in lawful money of the United States of America to
Lender at Lender's Address for payment in same day funds or other payment method
acceptable  to Lender.  All  repayments  of  principal on the Note shall be in a
minimum amount of $10,000, or a higher integral multiple of $10,000.

         (d) Condition Precedent to Initial Advance. The obligation of Lender to
make its initial Advance is subject to the condition precedent that Lender shall
have received on or before the day of such Advance the  following,  each in form
and substance  satisfactory to Lender and properly executed by Borrower or other
appropriate  parties:  (i) the Note duly  executed by Borrower;  (ii) such other
documents,  opinions,  certificates  and  evidences  as  Lender  may  reasonably
request;  and (iii) reimbursement in full for all costs and expenses (including,
without limitation, legal fees and expenses) incurred by Lender in entering into
this lending arrangement.

         (e) Conditions Precedent to Each Advance. In addition to the conditions
precedent  stated  elsewhere  herein,  Lender shall not be obligated to make any
Advance unless: (i) the representations and warranties  contained in paragraph 4
are true and  correct  in all  material  respects  on and as of the date of such
Advance as though made on and as of such date;  (ii) on the date of the Advance,
no Event of  Default,  and no event  which,  with the lapse of time or notice or
both,  could become an Event of Default,  and no breach or threatened  breach by
Borrower, has occurred under this Note or any other contract, agreement,

<PAGE>

document,  instrument  or  certificate  executed by  Borrower  and Lender (or by
Borrower  for the  benefit of  Lender);  (iii) there shall have been no material
adverse  change,  as determined  by Lender in its  reasonable  judgment,  in the
financial  condition  or  business of  Borrower;  (iv)  Borrower  shall not have
previously  provided notice to Lender of a Qualifying Equity Financing  pursuant
to  subsection  3(c);  (v) Lender  shall  have  received  such other  approvals,
opinions, documents,  certificates or evidences as Lender may reasonably request
(in  form  and  substance   reasonably   satisfactory   to  Lender);   and  (vi)
reimbursement in full for all costs and expenses (including, without limitation,
legal  fees and  expenses)  incurred  by Lender in  entering  into this  lending
arrangement or making any  additional  advances  hereunder.  Each request for an
Advance shall be deemed a representation by Borrower that the conditions of this
subsection have been met.

         (f) Outstanding  Balance in Excess of One Million  Dollars.  If, at any
time, the Outstanding  Balance (as  hereinafter  defined) is equal to or exceeds
One Million Dollars  ($1,000,000),  the Borrower,  on the first such occurrence,
shall  pay to  Lender a  non-refundable  fee  equal to one  percent  (1%) of the
Maximum Principal Amount.

3.       CONVERSION:

         (a) Qualifying Equity Financing.  A "Qualifying Equity Financing" shall
mean any equity financing or series of related equity  financings,  occurring on
or before the Maturity Date, in which  Borrower  sells equity  securities to any
one or more parties (including,  without limitation,  Lender and any of Lender's
affiliates) and obtains net proceeds  (excluding  conversion of this Note) in an
amount not less than Two Million Five Hundred Thousand Dollars ($2,500,000).

         (b) Conversion.  At the closing of any Qualifying Equity Financing, the
entire outstanding balance of this Note (including  principal,  interest and any
other amounts due  hereunder,  the  "Outstanding  Balance")

<PAGE>

shall,  at the sole  discretion of Borrower,  be either (i) paid in full by wire
transfer of immediately  available  funds or (ii) converted into common stock of
Borrower using a conversion price of $2.00 per share (the  "Conversion  Price").
If, at the maturity date,  including extensions thereof, the Outstanding Balance
has not been  paid in full,  the  Borrower  shall  have 90 days in which to make
payment.  If, at the end of the 90-day period,  the Lender has not received full
payment of the Outstanding Balance, then the Lender has the option of converting
the Outstanding Balance into capital stock of Borrower at the Conversion Price.

         (c) Notice. Borrower shall provide the Bank and Lender with at least 30
days prior written  notice of the closing of any  Qualifying  Equity  Financing,
delivered to the address for such party last shown on the records of Borrower or
given by such party to Borrower for the purpose of notice.

         (d) Issuance of Shares. If this Note is converted into capital stock of
Borrower  pursuant to this  subsection,  Borrower shall prior to or concurrently
with such  conversion,  deliver  to Lender a written  statement  specifying  the
amount of the  Outstanding  Balance,  the number and a description  of shares of
capital stock issuable upon such conversion and the date of such conversion.  As
promptly as practicable  after such  conversion,  Borrower will, at its expense,
issue and deliver to Lender,  upon  surrender  of this Note,  a  certificate  or
certificates  for the number of full shares of capital stock  issuable upon such
conversion.

         (e)      No Further Advances.  After the occurrence of a Qualifying
Equity  Financing,  Lender shall have no obligation to make any advance of any
kind to Borrower under this Note.

         (f) Adjustments Upon Dilution. The number of shares of capital stock of
Borrower to be received upon conversion of the Outstanding  Balance hereunder by
Lender (the "Stock") shall be subject

<PAGE>

to adjustment as follows: (i) in the event there is a subdivision or combination
of the  outstanding  shares of Stock into a larger or smaller  number of shares,
the number of shares of Stock  receivable  upon  conversion  of the  Outstanding
Balance shall be increased or reduced in the same  proportion as the increase or
decrease in the  outstanding  shares of Stock;  (ii) if the  Company  declares a
dividend on Stock payable in Stock or  securities  convertible  into Stock,  the
number of shares of Stock receivable upon conversion of the Outstanding  Balance
shall be increased, as of the record date for determining which holders of Stock
shall be entitled to receive such dividend, in proportion to the increase in the
number of outstanding shares of Stock as a result of such dividend. Whenever the
number of shares of Stock  receivable  upon  conversion  is  adjusted  as herein
provided,  the Conversion  Price shall be adjusted by multiplying the applicable
Conversion  Price  immediately  prior  to such  adjustment  by a  fraction,  the
numerator  of which  shall be the  number  of shares  of Stock  receivable  upon
conversion  immediately  prior to such  adjustment and the  denominator of which
shall be the  number  of  shares  of Stock  receivable  immediately  after  such
adjustment.

failure to pursue some remedy,  acceptance  of late  payments,  or acceptance of

         (a)  Rate:  The  principal  balance  of  this  Note  from  time to time
remaining  unpaid prior to maturity shall bear interest at the Interest Rate per
annum stated above. On each interest payment date and on the Maturity Date,

<PAGE>

interest  shall be  calculated  on the  amount of each  advance  of the  Maximum
Principal Amount of this Note, from the date of each such advance.

         (b) Maximum Lawful  Interest:  The term "Maximum Lawful Rate" means the
maximum rate of interest and the term "Maximum  Lawful Amount" means the maximum
amount of interest that is permissible under applicable state or federal law for
the type of loan evidenced by this Note. If the Maximum Lawful Rate is increased
by statute or other  governmental  action  subsequent  to the date of this Note,
then the new  Maximum  Lawful  Rate  shall be  applicable  to this Note from the
effective date thereof, unless otherwise prohibited by applicable law.

         (c)  Spreading of  Interest:  Because of the  possibility  of irregular
periodic  balances of principal or premature  payment,  the total  interest that
will accrue  under this Note cannot be  determined  in advance.  Lender does not
intend to contract for, charge,  or receive more than the Maximum Lawful Rate or
Maximum  Lawful  Amount  permitted  by  applicable  state or federal law, and to
prevent  such an  occurrence  Lender  and  Borrower  agree  that all  amounts of
interest,  whenever contracted for, charged, or received by Lender, with respect
to the loan of money  evidenced  by this  Note,  shall be spread,  prorated,  or
allocated over the full period of time this Note is unpaid, including the period
of any renewal or extension of this Note.  If demand for payment of this Note is
made by Lender  prior to the full  stated  term,  the total  amount of  interest
contracted for, charged, or received to the time of such demand shall be spread,
prorated, or allocated along with any interest thereafter accruing over the full
period of time that this Note  thereafter  remains  unpaid  for the  purpose  of
determining if such interest exceeds the Maximum Lawful Amount.

         (d) Excess Interest: At maturity (whether by acceleration or otherwise)
or on earlier final payment of this Note,  Lender shall compute the total amount
of interest  that has been  contracted  for,

<PAGE>

charged,  or  received  by Lender or  payable  by  Borrower  under this Note and
compare such amount to the Maximum Lawful Amount that could have been contracted
for, charged, or received by Lender. If such computation reflects that the total
amount of interest that has been contracted for, charged,  or received by Lender
or payable by Borrower  exceeds the Maximum  Lawful  Amount,  then Lender  shall
apply such  excess to the  reduction  of the  principal  balance  and not to the
payment of interest;  or if such excess  interest  exceeds the unpaid  principal
balance,  such excess shall be refunded to Borrower.  This provision  concerning
the crediting or refund of excess  interest  shall  control and take  precedence
over  all  other  agreements  between  Borrower  and  Lender  so that  under  no
circumstances  shall the total interest  contracted for, charged, or received by
Lender exceed the Maximum Lawful Amount.

         (e) Interest After Default:  At Lender's  option,  the unpaid principal
balance  shall  bear  interest  after  maturity   (whether  by  acceleration  or
otherwise) at the "Default  Interest Rate." The Default  Interest Rate shall be,
at Lender's option,  (i) the Maximum Lawful Rate, if such Maximum Lawful Rate is
established  by  applicable  law; or (ii) the Interest  Rate stated on the first
page of this Note plus three (3) percentage points, if no Maximum Lawful Rate is
established  by applicable  law; or (iii) eighteen  percent (18%) per annum;  or
(iv) such lesser rate of interest as Lender in its sole discretion may choose to
charge;  but never  more than the  Maximum  Lawful  Rate or at a rate that would
cause the total  interest  contracted  for,  charged,  or  received by Lender to
exceed the Maximum Lawful Amount.

         (f)  Daily  Computation  of  Interest:   To  the  extent  permitted  by
applicable  law,  Lender at its option will calculate the per diem interest rate
or amount  based on the  actual  number of days in the year (365 or 366,  as the
case may be), and charge that per diem  interest  rate or amount each day. In no
event shall  Lender  compute the interest in a manner that would cause Lender to
contract for,  charge,  or receive interest that would exceed the Maximum Lawful
Rate or the Maximum Lawful Amount.

<PAGE>

2.       ADVANCES:

         (a)  Revolving  Line of  Credit.  Subject to and in  reliance  upon the
terms, conditions,  representations and warranties hereinafter set forth, Lender
agrees to make advances (an  "Advance") to Borrower from time to time during the
period from the date hereof to and  including  the Maturity Date in an aggregate
amount not to exceed the Maximum Principal  Amount.  Each Advance must be in the
minimum  amount of $10,000 or in a higher  integral  multiple of $10,000.  Funds
borrowed and repaid may be reborrowed,  so long as all  conditions  precedent to
Advances are met.  The purpose of the  Advances is to provide  funds to Borrower
for working capital and for other general business purposes of Borrower.

         (b) Making  Advances.  Each  Advance  shall be made within two business
days of written notice (or telephonic notice confirmed in writing) given by noon
(Austin,  Texas  time)  on a  business  day of  Lender  by  Borrower  to  Lender
specifying  the amount and date thereof (which may be the same business day) and
if sent by wired  funds,  at Lender's  option,  the wiring  instructions  of the
deposit account of Borrower to which such Advance is to be deposited.

         (c) Payments and  Computations.  Borrower shall make each payment under
this Note on the day when due in lawful money of the United States of America to
Lender at Lender's Address for payment in same day funds or other payment method
acceptable  to Lender.  All  repayments  of  principal on the Note shall be in a
minimum amount of $10,000, or a higher integral multiple of $10,000.

         (d) Condition Precedent to Initial Advance. The obligation of Lender to
make its initial Advance is subject to the condition precedent that Lender shall
have received on or before the day of such Advance the  following,  each in form
and substance  satisfactory to Lender and properly executed by Borrower or other
appropriate parties: (i) the Note duly executed by Borrower; (ii) an advance fee

<PAGE>

equal to three percent (3%) of the Maximum  Principal  Amount;  (iii) such other
documents,  opinions,  certificates  and  evidences  as  Lender  may  reasonably
request;  and (iv) reimbursement in full for all costs and expenses  (including,
without limitation, legal fees and expenses) incurred by Lender in entering into
this lending arrangement.

         (e) Conditions Precedent to Each Advance. In addition to the conditions
precedent  stated  elsewhere  herein,  Lender shall not be obligated to make any
Advance unless: (i) the representations and warranties  contained in paragraph 4
are true and  correct  in all  material  respects  on and as of the date of such
Advance as though made on and as of such date;  (ii) on the date of the Advance,
no Event of  Default,  and no event  which,  with the lapse of time or notice or
both,  could become an Event of Default,  and no breach or threatened  breach by
Borrower,  has  occurred  under  this  Note or any  other  contract,  agreement,
document,  instrument  or  certificate  executed by  Borrower  and Lender (or by
Borrower  for the  benefit of  Lender);  (iii) there shall have been no material
adverse  change,  as determined  by Lender in its  reasonable  judgment,  in the
financial  condition  or  business of  Borrower;  (iv)  Borrower  shall not have
previously  provided notice to Lender of a Qualifying Equity Financing  pursuant
to  subsection  3(c);  (v) Lender  shall  have  received  such other  approvals,
opinions, documents,  certificates or evidences as Lender may reasonably request
(in  form  and  substance   reasonably   satisfactory   to  Lender);   and  (vi)
reimbursement in full for all costs and expenses (including, without limitation,
legal  fees and  expenses)  incurred  by Lender in  entering  into this  lending
arrangement or making any  additional  advances  hereunder.  Each request for an
Advance shall be deemed a representation by Borrower that the conditions of this
subsection have been met.

<PAGE>

         3.       CONVERSION AND SALES OF COLLATERAL:

         (a) Qualifying Equity Financing.  A "Qualifying Equity Financing" shall
mean any equity financing or series of related equity  financings,  occurring on
or before the Maturity Date, in which  Borrower  sells equity  securities to any
one or more parties (including,  without limitation,  Lender and any of Lender's
affiliates) and obtains net proceeds  (excluding  conversion of this Note) in an
amount not less than Two Million Five Hundred Thousand Dollars ($2,500,000).

         (b) Conversion.  At the closing of any Qualifying Equity Financing, the
entire outstanding balance of this Note (including  principal,  interest and any
other amounts due  hereunder,  the  "Outstanding  Balance")  shall,  at the sole
discretion  of  Borrower,  be  either  (i)  paid in full  by  wire  transfer  of
immediately  available  funds or (ii)  converted  into common  stock of Borrower
using a conversion price of $2.00 per share (the "Conversion Price"). If, at the
maturity date,  including  extensions  thereof,  the Outstanding Balance has not
been paid in full, the Borrower shall have 90 days in which to make payment. If,
at the end of the 90-day period, the Lender has not received full payment of the
Outstanding  Balance,   then  the  Lender  has  the  option  of  converting  the
Outstanding Balance into capital stock of Borrower at the Conversion Price.

         (c) Notice. Borrower shall provide the Bank and Lender with at least 30
days prior written  notice of the closing of any  Qualifying  Equity  Financing,
delivered to the address for such party last shown on the records of Borrower or
given by such party to Borrower for the purpose of notice.

         (d) Issuance of Shares. If this Note is converted into capital stock of
Borrower  pursuant to this  subsection,  Borrower shall prior to or concurrently
with such  conversion,  deliver  to Lender a written  statement  specifying  the
amount of the Outstanding Balance, the number and a description of shares of

<PAGE>

capital stock issuable upon such conversion and the date of such conversion.  As
promptly as practicable  after such  conversion,  Borrower will, at its expense,
issue and deliver to Lender,  upon  surrender  of this Note,  a  certificate  or
certificates  for the number of full shares of capital stock  issuable upon such
conversion.

         (e)      No Further Advances.  After the occurrence of a Qualifying
Equity  Financing,  Lender shall have no obligation to make any advance of any
kind to Borrower under this Note.

         (f) Adjustments Upon Dilution. The number of shares of capital stock of
Borrower to be received upon conversion of the Outstanding  Balance hereunder by
Lender (the "Stock") shall be subject to adjustment as follows: (i) in the event
there is a subdivision or combination of the outstanding  shares of Stock into a
larger or  smaller  number of shares,  the number of shares of Stock  receivable
upon conversion of the Outstanding  Balance shall be increased or reduced in the
same proportion as the increase or decrease in the outstanding  shares of Stock;
(ii) if the Company  declares a dividend on Stock payable in Stock or securities
convertible into Stock, the number of shares of Stock receivable upon conversion
of the  Outstanding  Balance  shall  be  increased,  as of the  record  date for
determining  which holders of Stock shall be entitled to receive such  dividend,
in proportion to the increase in the number of outstanding  shares of Stock as a
result of such dividend.  Whenever the number of shares of Stock receivable upon
conversion  is  adjusted  as herein  provided,  the  Conversion  Price  shall be
adjusted by multiplying the applicable  Conversion  Price  immediately  prior to
such  adjustment  by a fraction,  the  numerator of which shall be the number of
shares of Stock receivable upon conversion  immediately prior to such adjustment
and the  denominator of which shall be the number of shares of Stock  receivable
immediately after such adjustment.

<PAGE>

         (g)  Sale  of  Collateral.   In  the  event  any  Collateral  is  sold,
quitclaimed,  transferred or otherwise  alienated,  Borrower  shall  immediately
apply one half of the proceeds  received at the closing of such  transaction  to
the outstanding principal balance and all accrued interest under this Note.

 4.      BORROWER'S REPRESENTATIONS AND WARRANTIES:  Borrower represents and
warrants to Lender as follows:

         (a)      Good  Standing.  Borrower is a duly formed  corporation,  duly

the date of this Note.

<PAGE>

         (e) No  Conflicting  Agreements.  There are no charter,  bylaw or stock

"EVENT OF DEFAULT"):

                  (i) There is default  in the  payment  of any  installment  of

                  (ii)  There is  default in the  performance  of any  covenant,

         such default after twenty (20) days' written notice to Borrower; or

                  (iii)  There is a  default,  breach  or  threatened  breach by
         Borrower  under  any  contract,

         lapse  of any  cure  period  expressly  set  forth  in  such  contract,
         agreement, instrument or certificate; or

                  (iv)     Borrower or any guarantor files for bankruptcy,
         becomes insolvent, or dissolves.

failure to pursue some remedy,  acceptance  of late  payments,  or acceptance of
partial  payment  by  Lender,  before  or  after  the  Maturity  Date,  does not
constitute a waiver by Lender of its  subsequent  right to strictly  enforce the
collection of this Note according to its terms.

         (d)      Other  Remedies  Not  Required: Lender  shall not be  required
to first file suit,  exhaust all remedies, or enforce its rights against any
security in order to enforce payment of this Note.

restrictions relating to the collection of attorney's fees.

         (f) Right of Set-Off. Borrower hereby authorizes Lender, to the maximum

Note are then matured.

6. LENDER'S  REMEDIES:  Upon the  occurrence of an Event of Default and while it
may  continue  uncured,  Lender,  without  notice of any kind,  may, at Lender's
option:  (i) by notice to Borrower,  terminate  its  obligation to fund Advances
hereunder;  (ii) declare the principal and accrued  interest  outstanding  under
this  Note,  in whole or in part,  immediately  due and  payable;  and/or  (iii)
exercise any other rights and remedies  available to Lender under this Note,  or
applicable  laws;  except  that  upon the  occurrence  of an  Event  of  Default
described  in  subsection  5(a)(iv),  all the  principal  and  accrued  interest
outstanding under this Note shall  automatically be immediately due and payable,

guarantor, or to any surety or endorser of this Note, or to any other person.

each agree that neither  this Note nor any amount owed under this Note  (whether
principal, interest or otherwise) is subject to that certain Security Agreement

<PAGE>

<PAGE>

REVOLVING  LINE OF  CREDIT:  This Note  evidences  a  revolving  line of credit.
Subject to the terms and conditions  contained herein, all or any portion of the
Maximum  Principal  Amount  of this  Note may be  borrowed,  paid,  repaid,  and
reborrowed,  from time to time prior to the Maturity  Date.  Each  borrowing and
repayment  hereunder will be (i) endorsed on an attachment to this Note, or (ii)
entered  in the books and  records of  Lender.  The books and  records of Lender
shall be prima facie evidence of all sums due Lender. If an Event of Default, or
breach or threatened breach by Borrower,  exists or has occurred under this Note
or any other contract, agreement,  document, instrument or certificate executed,
alone or together with third parties, by Borrower and Lender (or by Borrower for
the benefit of Lender),  then Lender  shall be under no  obligation  to make any
advance under this Note.

1.       INTEREST PROVISIONS:
         (a)  Rate:  The  principal  balance  of  this  Note  from  time to time
remaining  unpaid prior to maturity shall bear interest at the Interest Rate per
annum stated  above.  On each  interest  payment date and on the Maturity  Date,
interest  shall be  calculated  on the  amount of each  advance  of the  Maximum
Principal Amount of this Note, from the date of each such advance.

         (b) Maximum Lawful  Interest:  The term "Maximum Lawful Rate" means the
maximum rate of interest and the term "Maximum  Lawful Amount" means the maximum
amount of interest that is permissible under applicable state or federal law for
the type of loan evidenced by this Note. If the Maximum Lawful Rate is increased
by statute or other  governmental  action  subsequent  to the date of this Note,
then the new  Maximum  Lawful  Rate  shall be  applicable  to this Note from the
effective date thereof, unless otherwise prohibited by applicable law.

         (c)  Spreading of  Interest:  Because of the  possibility  of irregular
periodic  balances of principal or premature  payment,  the total  interest that
will accrue  under this Note cannot

<PAGE>

be determined in advance.  Lender does not intend to contract  for,  charge,  or
receive more than the Maximum Lawful Rate or Maximum Lawful Amount  permitted by
applicable  state or federal law, and to prevent such an  occurrence  Lender and
Borrower agree that all amounts of interest,  whenever  contracted for, charged,
or received by Lender, with respect to the loan of money evidenced by this Note,
shall be spread,  prorated,  or allocated over the full period of time this Note
is unpaid,  including  the period of any renewal or extension  of this Note.  If
demand for payment of this Note is made by Lender prior to the full stated term,
the total amount of interest contracted for, charged, or received to the time of
such demand  shall be spread,  prorated,  or  allocated  along with any interest
thereafter  accruing  over the full  period of time  that  this Note  thereafter
remains  unpaid for the  purpose of  determining  if such  interest  exceeds the
Maximum Lawful Amount.

         (d) Excess Interest: At maturity (whether by acceleration or otherwise)
or on earlier final payment of this Note,  Lender shall compute the total amount
of interest  that has been  contracted  for,  charged,  or received by Lender or
payable by  Borrower  under this Note and  compare  such  amount to the  Maximum
Lawful  Amount  that could have been  contracted  for,  charged,  or received by
Lender. If such computation  reflects that the total amount of interest that has
been  contracted  for,  charged,  or  received  by Lender or payable by Borrower
exceeds the Maximum  Lawful  Amount,  then Lender shall apply such excess to the
reduction of the  principal  balance and not to the payment of  interest;  or if
such excess interest exceeds the unpaid principal balance,  such excess shall be
refunded to  Borrower.  This  provision  concerning  the  crediting or refund of
excess  interest  shall control and take  precedence  over all other  agreements
between  Borrower  and  Lender so that  under no  circumstances  shall the total
interest  contracted  for,  charged,  or received  by Lender  exceed the Maximum
Lawful Amount.

         (e) Interest After Default:  At Lender's  option,  the unpaid principal
balance  shall  bear  interest  after  maturity   (whether  by  acceleration  or
otherwise) at the "Default  Interest Rate." The Default

<PAGE>

Interest Rate shall be, at Lender's option, (i) the Maximum Lawful Rate, if such
Maximum Lawful Rate is established by applicable  law; or (ii) the Interest Rate
stated on the first page of this Note plus three (3)  percentage  points,  if no
Maximum Lawful Rate is established by applicable law; or (iii) eighteen  percent
(18%) per annum;  or (iv) such  lesser  rate of  interest  as Lender in its sole
discretion may choose to charge;  but never more than the Maximum Lawful Rate or
at a rate that  would  cause the total  interest  contracted  for,  charged,  or
received by Lender to exceed the Maximum Lawful Amount.

         (f)  Daily  Computation  of  Interest:   To  the  extent  permitted  by
applicable  law,  Lender at its option will calculate the per diem interest rate
or amount  based on the  actual  number of days in the year (365 or 366,  as the
case may be), and charge that per diem  interest  rate or amount each day. In no
event shall  Lender  compute the interest in a manner that would cause Lender to
contract for,  charge,  or receive interest that would exceed the Maximum Lawful
Rate or the Maximum Lawful Amount.

2.       ADVANCES:

         (a)  Revolving  Line of  Credit.  Subject to and in  reliance  upon the
terms, conditions,  representations and warranties hereinafter set forth, Lender
agrees to make advances (an  "Advance") to Borrower from time to time during the
period from the date hereof to and  including  the Maturity Date in an aggregate
amount not to exceed the Maximum Principal  Amount.  Each Advance must be in the
minimum  amount of $10,000 or in a higher  integral  multiple of $10,000.  Funds
borrowed and repaid may be reborrowed,  so long as all  conditions  precedent to
Advances are met.  The purpose of the  Advances is to provide  funds to Borrower
for working capital and for other general business purposes of Borrower.

         (b) Making  Advances.  Each  Advance  shall be made within two business
days of written notice (or telephonic notice confirmed in writing) given by noon
(Austin,  Texas  time)  on a  business  day of  Lender  by  Borrower  to  Lender
specifying the amount and date thereof (which may be the same business day) and

<PAGE>

if sent by wired  funds,  at Lender's  option,  the wiring  instructions  of the
deposit account of Borrower to which such Advance is to be deposited.

         (c) Payments and  Computations.  Borrower shall make each payment under
this Note on the day when due in lawful money of the United States of America to
Lender at Lender's Address for payment in same day funds or other payment method
acceptable  to Lender.  All  repayments  of  principal on the Note shall be in a
minimum amount of $10,000, or a higher integral multiple of $10,000.

         (d) Condition Precedent to Initial Advance. The obligation of Lender to
make its initial Advance is subject to the condition precedent that Lender shall
have received on or before the day of such Advance the  following,  each in form
and substance  satisfactory to Lender and properly executed by Borrower or other
appropriate parties: (i) the Note duly executed by Borrower; (ii) an advance fee
equal to three percent (3%) of the Maximum  Principal  Amount;  (iii) such other
documents,  opinions,  certificates  and  evidences  as  Lender  may  reasonably
request;  and (iv) reimbursement in full for all costs and expenses  (including,
without limitation, legal fees and expenses) incurred by Lender in entering into
this lending arrangement.

         (e) Conditions Precedent to Each Advance. In addition to the conditions
precedent  stated  elsewhere  herein,  Lender shall not be obligated to make any
Advance unless: (i) the representations and warranties  contained in paragraph 4
are true and  correct  in all  material  respects  on and as of the date of such
Advance as though made on and as of such date;  (ii) on the date of the Advance,
no Event of  Default,  and no event  which,  with the lapse of time or notice or
both,  could become an Event of Default,  and no breach or threatened  breach by
Borrower,  has  occurred  under  this  Note or any  other  contract,  agreement,
document,  instrument  or  certificate  executed by  Borrower  and Lender (or by
Borrower for the benefit of Lender); (iii) there shall have been no material

<PAGE>

adverse  change,  as determined  by Lender in its  reasonable  judgment,  in the
financial  condition  or  business of  Borrower;  (iv)  Borrower  shall not have
previously  provided notice to Lender of a Qualifying Equity Financing  pursuant
to  subsection  3(c);  (v) Lender  shall  have  received  such other  approvals,
opinions, documents,  certificates or evidences as Lender may reasonably request
(in  form  and  substance   reasonably   satisfactory   to  Lender);   and  (vi)
reimbursement in full for all costs and expenses (including, without limitation,
legal  fees and  expenses)  incurred  by Lender in  entering  into this  lending
arrangement or making any  additional  advances  hereunder.  Each request for an
Advance shall be deemed a representation by Borrower that the conditions of this
subsection have been met.

3.       CONVERSION AND SALES OF COLLATERAL:

         (a) Qualifying Equity Financing.  A "Qualifying Equity Financing" shall
mean any (i) equity  financing or series of related equity  financings,  or (ii)
subordinated  debt  financing  or series of related debt  financings  treated or
characterized  by the Bank as equity  financing or (iii) any  combination of (i)
and (ii),  occurring on or before the Maturity  Date,  in which  Borrower  sells
equity  securities to any one or more parties  (including,  without  limitation,
Lender and any of Lender's affiliates), or issues debt, and obtains net proceeds
(excluding  conversion of this Note) in an amount not less than Two Million Five
Hundred Thousand Dollars ($2,500,000).

         (b) Conversion.  At the closing of any Qualifying Equity Financing, the
entire outstanding balance of this Note (including  principal,  interest and any
other amounts due  hereunder,  the  "Outstanding  Balance")  shall,  at the sole
discretion  of  Borrower,  be  either  (i)  paid in full  by  wire  transfer  of
immediately  available  funds or (ii)  converted  into common  stock of Borrower
using a conversion price of $2.00 per share (the "Conversion Price"). If, at the
maturity date,  including  extensions  thereof,  the Outstanding Balance has not
been paid in full, the Borrower shall have 90 days in which to make payment. If,
at the end of the 90-day period, the Lender has not received full payment of the

<PAGE>

Outstanding  Balance,   then  the  Lender  has  the  option  of  converting  the
Outstanding Balance into capital stock of Borrower at the Conversion Price.

         (c) Notice. Borrower shall provide the Bank and Lender with at least 30
days prior written  notice of the closing of any  Qualifying  Equity  Financing,
delivered to the address for such party last shown on the records of Borrower or
given by such party to Borrower for the purpose of notice.

         (d) Issuance of Shares. If this Note is converted into capital stock of
Borrower  pursuant to this  subsection,  Borrower shall prior to or concurrently
with such  conversion,  deliver  to Lender a written  statement  specifying  the
amount of the  Outstanding  Balance,  the number and a description  of shares of
capital stock issuable upon such conversion and the date of such conversion.  As
promptly as practicable  after such  conversion,  Borrower will, at its expense,
issue and deliver to Lender,  upon  surrender  of this Note,  a  certificate  or
certificates  for the number of full shares of capital stock  issuable upon such
conversion.

         (e)      No Further Advances.  After the occurrence of a Qualifying
Equity  Financing,  Lender shall have no obligation to make any advance of any
kind to Borrower under this Note.

         (f) Adjustments Upon Dilution. The number of shares of capital stock of
Borrower to be received upon conversion of the Outstanding  Balance hereunder by
Lender (the "Stock") shall be subject to adjustment as follows: (i) in the event
there is a subdivision or combination of the outstanding  shares of Stock into a
larger or  smaller  number of shares,  the number of shares of Stock  receivable
upon conversion of the Outstanding  Balance shall be increased or reduced in the
same proportion as the increase or decrease in the outstanding  shares of Stock;
(ii) if the Company  declares a dividend on Stock payable in Stock or securities
convertible into Stock, the number of shares of Stock receivable upon conversion

<PAGE>

of the  Outstanding  Balance  shall  be  increased,  as of the  record  date for
determining  which holders of Stock shall be entitled to receive such  dividend,
in proportion to the increase in the number of outstanding  shares of Stock as a
result of such dividend.  Whenever the number of shares of Stock receivable upon
conversion  is  adjusted  as herein  provided,  the  Conversion  Price  shall be
adjusted by multiplying the applicable  Conversion  Price  immediately  prior to
such  adjustment  by a fraction,  the  numerator of which shall be the number of
shares of Stock receivable upon conversion  immediately prior to such adjustment
and the  denominator of which shall be the number of shares of Stock  receivable
immediately after such adjustment.

failure to pursue some remedy,  acceptance  of late  payments,  or acceptance of
partial  payment  by  Lender,  before  or  after  the  Maturity  Date,  does not

         3.       Agreement Among the Preferred Holders and APS.
                  ---------------------------------------------

                  3.1  Transfer  Notice.  If at any time a  Preferred  Holder or
Preferred  Holders  propose to transfer  Equity  Securities to one or more third
parties (the "Selling Preferred Holders") pursuant to an understanding with such
third parties (a "Transfer"),  then the Selling Preferred Holders shall give the
Company and APS written notice of the Selling  Preferred  Holders'  intention to
make the Transfer (the "Transfer  Notice"),  which Transfer Notice shall include
(i) a description of the Equity Securities to be transferred ("Offered Shares"),
(ii) the identity of the prospective  transferee(s)  and (iii) the consideration
and the material terms and conditions upon which the proposed  Transfer is to be
made. The Transfer Notice shall certify that the Selling  Preferred Holders have
received a bona fide offer from the prospective  transferee(s) and in good faith
believes a binding  agreement  for the Transfer is  obtainable  on the terms set
forth in the Transfer  Notice.  The Transfer Notice shall also include a copy of
any written proposal, term sheet or letter of intent or other agreement relating
to the proposed  Transfer,  and shall state that APS has ten (10)  business days
following its receipt of the Transfer  Notice within which to notify the Selling
Preferred Holders of any exercise of APS's rights under this Agreement.

                  3.2      Right of Co-Sale.
                           ----------------

                           (a)      APS, upon notifying in writing the Selling
Preferred  Holders  identified  in the Transfer  Notice within ten (10) business
days after receipt of the Transfer  Notice,  shall have the right to participate
in such sale of Equity  Securities on the same terms and conditions as specified
in the Transfer  Notice.  APS's notice to the Selling  Preferred  Holders  shall
indicate  the  number of shares of  Equity  Securities  that APS  wishes to sell
(subject to subsection (b) below) under its right to participate.  To the extent
APS  exercises  its  right of  participation  in  accordance  with the terms and
conditions set forth below,  the number of shares of Equity  Securities that the
Selling  Preferred  Holders may sell in the  Transfer  shall be  correspondingly
reduced.

                           (b)      APS may sell all or any part of that  number
of shares of Equity  Securities equal to the product obtained by multiplying (i)
the  aggregate  number of shares of Equity  Securities  covered by the  Transfer
Notice by (ii) a  fraction,  the  numerator  of which is the number of shares of
Common Stock owned by APS on the date of the Transfer Notice and the denominator
of which is the total  number of shares  of Common  Stock  (including  shares of
Common Stock issuable upon  conversion of Preferred  Stock) owned by the Selling
Preferred Holders and APS on the date of the Transfer Notice.

<PAGE>

                           (c)      APS shall effect its  participation  in the
sale by promptly delivering to the Selling Preferred Holders for transfer to the
prospective purchaser one or more certificates,  properly endorsed for transfer,
which represent the Common Stock which APS elects to sell.

                           (d)      The  stock  certificate  or  certificates
that APS delivers to the Selling  Preferred  Holders  pursuant to Section 3.2(c)
shall be transferred to the prospective  purchaser upon the  consummation of the
sale of the Equity Securities pursuant to the terms and conditions  specified in
the  Transfer  Notice,  and the Selling  Preferred  Holders  shall  concurrently
therewith cause to be remitted to APS that portion of the sale proceeds to which
APS is entitled by reason of its  participation in such sale. To the extent that
any  prospective  purchaser  prohibits such  assignment or otherwise  refuses to
purchase  shares or other  securities  from APS, the Selling  Preferred  Holders
shall not sell to such prospective  purchaser any Equity  Securities  unless and
until,  simultaneously  with such sale,  the  Selling  Preferred  Holders  shall
purchase such shares or other securities from APS for the same consideration and
on the same terms and  conditions  as the  proposed  transfer  described  in the
Transfer Notice.

                  3.3  Non-Exercise  of Rights.  To the extent  that APS has not
exercised its rights to participate in the sale of the Offered Shares within the
time periods  specified in Section 3.2, the Selling Preferred Holders shall have
a period of thirty  (30)  business  days from the  expiration  of such rights in
which to sell the  Offered  Shares  upon  terms and  conditions  (including  the
purchase price) no more favorable than those specified in the Transfer Notice to
the third-party transferee(s) identified in the Transfer Notice. The third-party
transferee(s)  shall  acquire  the Offered  Shares free and clear of  subsequent
co-sale rights under this Agreement.  In the event the Selling Preferred Holders
do not  consummate  the sale or  disposition  of the Offered  Shares  within the
thirty (30) business day period from the expiration of these rights, the co-sale
rights shall  continue to be applicable  to any  subsequent  disposition  of the
Offered  Shares by the  Selling  Preferred  Holders  until such right  lapses in
accordance  with the  terms of this  Agreement.  Furthermore,  the  exercise  or
non-exercise  of APS's rights under this  Section 3 to  participate  in sales of
Equity  Securities by the Selling  Preferred  Holders shall not adversely affect
APS's rights to  subsequently  participate  in sales of Equity  Securities  by a
Preferred Holder.

                  3.4  Limitations  to  Co-Sale  Rights.   Notwithstanding   the
provisions  of Sections 3.1 and 3.2 of this  Agreement,  a Preferred  Holder may
sell or otherwise assign,  with or without  consideration,  Equity Securities to
(i) any person or entity controlling, controlled by or under common control with
the Preferred Holder or (ii) partners, members or stockholders of such Preferred
Holder (in each case,  except where such  person(s) were admitted as, or became,
partners,  members  or  stockholders  for the  primary  purpose of  effecting  a
transfer of Equity  Securities exempt under this Section 3.4), or in the case of
individuals,  to members of such Preferred  Holder's immediate family or a trust
for the  benefit  of such  immediate  family  members;  provided  that each such
transferee  or  assignee,  prior to the  completion  of the sale,  transfer,  or
assignment  shall  have  executed  documents  assuming  the  obligations  of the
Preferred   Holder  under  this  Agreement  with  respect  to  the   transferred
securities.  The Preferred Holders acknowledge and agree that the co-sale rights
granted in Sections  3.1 and 3.2 of this  Agreement  apply to any sale of Equity
Securities  by any  Preferred  Holder  pursuant to Section  2.6 of that  certain
Investors Rights Agreement, dated as of October 31, 1997, among the Company and

<PAGE>

the other parties thereto,  unless APS is the party that triggered the Preferred
Holders'  rights to sale Equity  Securities  under  Section 2.6 of the Investors
Rights Agreement.  This Agreement shall not apply,  however,  to any transaction
described in Section 8 hereof.

                  3.5      Prohibited Transfers.
                           --------------------

                           (a)      In  the  event  a  Preferred  Holder  should
sell any Equity  Securities in  contravention of the co-sale rights of APS under
Section 3.2 (a "Prohibited  Transfer"),  APS, in addition to such other remedies
as may be  available at law, in equity or  hereunder,  shall have the put option
provided  below,  and the  Preferred  Holder  shall be  bound by the  applicable
provisions of such option.

                           (b)      In the event of a Prohibited Transfer,  APS
shall  have the right to sell to the  Preferred  Holder  the number of shares of
Common  Stock  equal to the  number of shares APS would  have been  entitled  to
transfer  to the  third-party  transferee(s)  under  Section  3.2 hereof had the
Prohibited  Transfer been effected  pursuant to and in compliance with the terms
hereof. Such sale shall be made on the following terms and conditions:

                                    (i)  The price per share at which the shares
are to be sold to a Preferred Holder under this subsection (b) shall be equal to
the effective price per share of Common Stock (on an as converted basis) paid by
the  third-party  transferee(s)  to  the  Preferred  Holder  in  the  Prohibited
Transfer. The Preferred Holder shall also reimburse APS for any and all fees and
expense, including legal fees and expenses, incurred pursuant to the exercise or
the attempted exercise of APS's rights under Section 3.

                                    (ii)    Within  ninety  (90) days after the
later of the dates on which APS (A) received  notice of the Prohibited  Transfer
or (B)  otherwise  became  aware  of the  Prohibited  Transfer,  APS  shall,  if
exercising  the  option  created  hereby,  deliver to the  Preferred  Holder the
certificate or certificates  representing shares to be sold, each certificate to
be properly endorsed for transfer.

                                    (iii)   The  Preferred  Holder  shall,  upon

receipt of the  certificate  or  certificates  for the shares to be sold by APS,
pursuant to this subsection  (b), pay the aggregate  purchase price therefor and
the amount of reimbursable fees and expenses,  as specified in subsection (b)(i)
above, in cash or by other means acceptable to APS.

                                    (iv)  Unless and until the Preferred  Holder
has fully satisfied its payment and other obligations under this  Section3.5(b),
(A) any attempt by a Preferred Holder to transfer Equity Securities in violation
of Section 3 hereof shall be void, and (B) the Company agrees it will not effect
such a transfer  nor will it treat any  alleged  transferee(s)  as the holder of
such shares without the written consent of APS.

         4.       Assignments  and  Transfers;  No Third Party  Beneficiaries.
This  Agreement and the rights and  obligations of the parties  hereunder  shall
inure to the  benefit  of, and be binding  upon,  their  respective  successors,
assigns and legal representatives, but shall not otherwise be for the benefit of

the constant  interest  rate of eight  percent per annum.  The twelfth and final
combined  principal and interest  payment shall be due on the Quarterly  Payment
Date of September 1, 2004 and shall include the remaining outstanding balance on
this Note plus all accrued and unpaid interest  hereunder.  Notwithstanding  the
foregoing,  if FemPartners  conducts an initial public  offering or other public
sale of its  common  stock,  this Note  shall  mature  and shall  become due and
payable upon the latter of (i) September 1, 2002 or (ii) the fifth  business day
after the date of such initial public offering or other public sale.

1.       INTEREST PROVISIONS:

(a)      Rate:  The principal  balance of this Note form time to time  remaining
         unpaid prior to maturity  shall bear  interest at the Interest Rate per
         annum stated above.  Interest shall be calculated on the amount of each
         advance of the Principal Amount of this Note from the date of each such
         advance.

(b)      Maximum  Lawful  Interest:  The term  "Maximum  Lawful  Rate" means the
         maximum rate of interest and the term "Maximum Lawful Amount" means the
         maximum amount of interest that is permissible  under  applicable state
         or federal  law for the type of loan  evidenced  by this  Note.  If the
         Maximum  Lawful  Rate is  increased  by statute  or other  governmental
         action subsequent to the date of this Note, then the new Maximum Lawful
         Rate shall be applicable to this Note from the effective  date thereof,
         unless otherwise prohibited by applicable law.

(c)      Spreading  of  Interest:  Because of the  possibility  of  irregular
         periodic  balances of  principal  or premature  payment,  the total
         interest that will accrue under this Note cannot be determined in
         advance. Lender does not intend to contract  for,  charge or receive
         more than the Maximum Lawful Rate or Maximum Lawful Amount permitted by
         applicable  state or federal law, and to prevent such an occurrence
         Lender and Borrower agree that all amounts of interest,  whenever
         contracted  for,  charged,  or received by Lender, with respect to the
         loan of money  evidenced by this Note,  shall be spread,  prorated,  or
         allocated over the full  period of time this Note is unpaid,  including
         the period of any renewal or  extension  of this Note.  If demand  for
         payment of this Note is made by Lender  prior to the full stated  term,
         the total amount of interest  contracted  for,  charged,  or  received
         to the time of such demand  shall be spread, prorated,  or allocated
         along with any  interest  thereafter  accruing  over the full period of
         time that this Note  thereafter  remains unpaid for the purpose of
         determining if such interest  exceeds the Maximum Lawful Amount.



<PAGE>

(d) Excess  Interest:  At maturity  (whether by acceleration or otherwise) or on
earlier  final  payment of this Note,  Lender shall  compute the total amount of
interest that has been contracted for, charged, or received by Lender or payable
by Borrower under this Note and compare such amount to the Maximum Lawful Amount
that could have been contracted  for,  charged,  or received by Lender.  If such
computation  reflects that the total amount of interest that has been contracted
for,  charged,  or received by Lender or payable by Borrower exceeds the Maximum
Lawful  Amount,  then Lender  shall apply such  excess to the  reduction  of the
principal balance and not to the payment of interest; or if such excess interest
exceeds the unpaid principal balance, such excess shall be refunded to Borrower.
This  provision  concerning  the  crediting or refund of excess  interest  shall
control and take precedence over all other agreements

<PAGE>

between  Borrower  and  Lender so that  under no  circumstances  shall the total
interest  contracted  for,  charged,  or received  by Lender  exceed the Maximum
Lawful Amount.

(e) Interest After Default:  At Lender's option,  the unpaid  principal  balance
shall bear interest after maturity (whether by acceleration or otherwise) at the
"Default Interest Rate." The Default Interest Rate shall be, at Lender's option,
(i) the Maximum  Lawful Rate,  if such  Maximum  Lawful Rate is  established  by
applicable  law; or (ii) the Interest Rate stated on the first page of this Note
plus  five (5)  percentage  points  per  annum,  if no  Maximum  Lawful  Rate is
established  by applicable  law; or (iii) eighteen  percent (18%) per annum;  or
(iv) such lesser rate of interest as Lender in its sole discretion may choose to
charge;  but never  more than the  Maximum  Lawful  Rate or at a rate that would
cause the total  interest  contracted  for,  charged,  or  received by Lender to
exceed the Maximum Lawful Amount.

(f)      Daily  Computation of Interest:  To the extent  permitted by applicable
         law,  Lender at its option will calculate the per diem interest rate or
         amount  based on the actual  number of days in the year (365 or 366, as
         the case may be), and charge that per diem interest rate or amount each
         day. In no event  shall  Lender  compute the  interest in a manner that
         would cause Lender to contract for,  charge,  or receive  interest that
         would exceed the Maximum Lawful Rate or the Maximum Lawful Amount.

2.       DEFAULT PROVISIONS:

(a)      EVENTS OF DEFAULT AND  ACCELERATION  OF  MATURITY:  LENDER  MAY,  AFTER
         THIRTY (30) DAYS' WRITTEN NOTICE TO BORROWER AND BORROWER'S  FAILURE TO
         CURE WITHIN SUCH 30-DAY  PERIOD AND WITHOUT  FURTHER  NOTICE OR DEMAND,
         (except as otherwise  required by statute),  ACCELERATE THE MATURITY OF
         THIS NOTE AND  DECLARE  THE ENTIRE  UNPAID  PRINCIPAL  BALANCE  AND ALL
         ACCRUED INTEREST AT ONCE DUE AND PAYABLE IF:

         (i)      There is default in the  payment of any  installment  of
                  principal,  interest,  or any other sum required to be paid
                  under the terms of this Note; or

         (ii)     There  is  default  in  the   performance   of  any  covenant,
                  condition,  or agreement contained in this Note, including any
                  instrument securing the payment of this Note.

     (b)  WAIVER BY  BORROWER:  EXCEPT AS PROVIDED  IN  PARAGRAPH  2(a)  HEREOF,
          BORROWER  AND ALL OTHER  PARTIES  LIABLE FOR THIS NOTE WAIVE,  DEMAND,
          NOTICE  OF  INTENT  TO  DEMAND,  PRESENTMENT  FOR  PAYMENT,  NOTICE OF
          NONPAYMENT,  PROTEST,  NOTICE OF PROTEST,  GRACE,  NOTICE OF DISHONOR,
          NOTICE OF INTENT TO ACCELERATE  MATURITY,  NOTICE OF  ACCELERATION  OF
          MATURITY, AND DILIGENCE IN COLLECTION.  EACH MAKER, SURETY,  ENDORSER,
          AND GUARANTOR OF THIS NOTE WAIVES AND AGREES TO ONE OR MORE EXTENSIONS
          FOR ANY PERIOD OR PERIODS OF TIME, AND ANY PARTIAL PAYMENTS, BEFORE OR
          AFTER  MATURITY,  WITHOUT  PREJUDICE TO THE HOLDER OF THIS NOTE.  EACH
          MAKER,

<PAGE>

          SURETY, ENDORSER, AND GUARANTOR WAIVES NOTICE OF ANY AND ALL RENEWALS,
          EXTENSIONS, REARRANGEMENTS, AND MODIFICATIONS OF THIS NOTE.

(c)      Non-waiver  by Lender:  Any previous  extension  of time,  forbearance,
         failure  to  pursue  some  remedy,  acceptance  of  late  payments,  or
         acceptance of partial payment by Lender, before or after maturity, does
         not constitute a waiver by Lender of its  subsequent  right to strictly
         enforce the collection of this Note according to its terms.

(d)      Other  Remedies Not Required:  Lender shall not be required to first
file suit,  exhaust all remedies,  or enforce its rights against any security in
order to enforce payment of this Note.

(e)      Joint and Several Liability: Each Borrower who signs this Note, and all
         of the other  parties  liable for the  payment  of this  Note,  such as
         guarantors,  endorsers,  and sureties, are jointly and severally liable
         for the payment of this Note.

(f)      Attorney's  Fees:  If Lender  requires  the  services of an attorney to
         enforce the payment of this Note, or if this Note is collected  through
         any  lawsuit,  probate,   bankruptcy,  or  other  judicial  proceeding,
         Borrower  agrees  to pay  Lender  an  amount  equal  to its  reasonable
         attorney's  fees and other  collection  costs.  This provision shall be
         limited  by  any  applicable  statutory  restrictions  relating  to the
         collection of attorney's fees.

     3.   SUBORDINATION:  All  indebtedness,  obligations and liabilities of any
          kind of the  Borrower  from time to time  owing  with  respect to this
          Note,  including  without  limitation,  principal and interest thereon
          (such  indebtedness,  obligations  and  liabilities  are  collectively
          referred to as "Subordinated Debt") is subordinate and junior in right
          of payment  and  collection  in full of all amounts  owing  (including
          without  limitation,  interest accruing after the filing of a petition
          initiating any proceeding  pursuant to any bankruptcy law with respect
          to the Borrower as debtor) (i) under the primary senior loan agreement
          or credit agreement (as such loan agreement or credit agreement may be
          amended,  renewed,  extended,  increased,   substituted,   refinanced,
          restructured,  replaced,  supplemented or otherwise modified from time
          to time (the "Senior Credit Agreement"), of FemPartners, designated by
          FemPartners  in  accordance  with Section 3(j) upon written  notice to
          Borrower  and  Lender  with the  financial  institution  or  financial
          institutions party thereto (together with their respective  successors
          and assigns, collectively the "Senior Creditor"), and the other credit
          documents  or  loan  documents  referred  to  in  such  Senior  Credit
          Agreement   (the   "Loan   Documents"),   and  (ii)  under  any  other
          indebtedness  of FemPartners or Borrower now or hereafter  outstanding
          in  favor  of any  such  Senior  Creditor  unless,  in the case of any
          particular  indebtedness,  the  instrument  creating or evidencing the
          same or pursuant to which the same is outstanding  expressly  provides
          that such indebtedness  shall not be senior in right of payment to the
          Subordinated  Debt (foregoing  clauses (i) through (ii)  constituting,
          collectively,  the "Senior  Obligations")  on the following  terms and
          conditions:


<PAGE>

     (a)  No payment by the Borrower on the Subordinated  Debt (whether pursuant
          to  the  terms  of the  Subordinated  Debt  or  upon  acceleration  or
          otherwise)  shall be made if, at the time of any such  payment,  there
          exists a material default,  as determined by the holders of the Senior
          Obligations  in their sole  discretion,  in the  payment of any Senior
          Obligations  (a "Senior  Payment  Default"),  and such Senior  Payment
          Default  shall  not have  been  cured or waived by or on behalf of the
          holders  of  such  Senior   Obligations.   In  addition,   during  the
          continuance of

<PAGE>

     any  other material  event of default,  as determined by the holders of the
          Senior  Obligations  in their  sole  discretion,  with  respect to any
          Senior  Obligations  pursuant  to which the  maturity  thereof  may be
          accelerated,  upon the giving by any holder of the Senior  Obligations
          (or any agent,  trustee, or representative  thereof) of written notice
          to the Lender,  no such payment may be made by the  Borrower  upon the
          Subordinated  Debt  for  a  period  (the  "Payment  Blockage  Period")
          commencing  on the date of the giving of such notice and ending on the
          earlier of (x) 180 days  after the date of the  giving of such  notice
          and (y) if a Remedy  Blockage period referred to in Section 3(b)(X) is
          in effect,  on the date of expiration of such Remedy Blockage  Period.
          No event of default  which  existed or was  continuing  on the date of
          commencement of any Payment Blockage Period with respect to the Senior
          Obligations  shall be, or be made,  the  basis for  commencement  of a
          second Payment  Blockage  Period whether within or without a period of
          180  consecutive  days  unless  such event of default  shall have been
          cured for a period of not less than 30  consecutive  days.  During any
          period in which payments on the  Subordinated  Debt are not restricted
          pursuant to this Section 3(a),  the holders of the  Subordinated  Debt
          shall be entitled to receive all payments due and owing in  accordance
          with the terms of the Subordinated  Debt,  including any payments that
          were previously restricted in accordance with this Section 3(a).

     (b)  During  certain  periods  specified  below  (each a  "Remedy  Blockage
          Period"),  the holders of the  Subordinated  Debt will not have any of
          the following rights (a "Remedy Blockage"):  (i) to demand, sue for or
          take from or on behalf of the  Borrower,  by  set-off  or in any other
          manner,  any  moneys  which  may  then or  thereafter  be owing by the
          Borrower on the Subordinated  Debt, (ii) to commence,  or to join with
          any person or entity in  commencing,  any suit,  action or  proceeding
          against the  Borrower  (A) to enforce  payment of or to collect all or
          any  portion  of the  Subordinated  Debt or (B) to  commence  judicial
          enforcement  of any of the rights and remedies  under the documents or
          instruments  governing the Subordinated  Debt or applicable law, (iii)
          to  accelerate  the  principal  of or interest on or any other  amount
          under the Subordinated Debt, or (iv) to commence,  or to join with any
          person  or  entity  in  commencing,  against  Borrower  or  any of its
          property a bankruptcy,  reorganization,  insolvency,  receivership  or
          other similar  proceeding (except that the holders of the Subordinated
          Debt may (1) charge  interest at a default rate,  (2)  accelerate  the
          Subordinated  Debt after the Senior  Obligations  are  accelerated  or
          otherwise take such actions in respect of the Subordinated Debt as are
          taken by the  holders  of the  Senior  Obligations  in  respect of the
          Senior  Obligations after such actions are taken by the holders of the
          Senior  Obligations,  (3) sue for  specific  performance,  but not for
          damages or other sums of money, or obtain injunctive relief, in either
          case,  in respect of the covenants of the  Subordinated  Debt which do
          not require,  directly or  indirectly,  the payment by the Borrower of
          money,  and (4) give notices and file law suits to prevent the running
          of the relevant  statute of limitations,  pursue rights in bankruptcy,
          reorganization,    insolvency,    receivership,   or   other   similar
          proceedings, and otherwise protect legal rights).

                  The Remedy Blockage Periods shall be as follows:
                           (X) if there  shall exist a default in the payment of
                  any  amounts  owing  under the  Subordinated  Debt (a "Payment
                  Default";  provided  that the  failure of Borrower to make any
                  payment, prepayment,  reimbursement or deposit with respect to
                  an obligation accelerated as a result of the occurrence of any
                  default of this Note which was a Non-monetary Default (defined
                  below) shall not be a Payment Default), the Remedy Blockage

<PAGE>

                  shall remain in effect for a Remedy Blockage Period ending 365
                  days after agent for the Senior Indebtedness  receives written
                  notice  from  any  holder  of the  Subordinated  Debt  (or any
                  designed  representative  thereof)  of the  occurrence  of the
                  Payment  Default,  unless  extended  as provided in clause (Y)
                  below and

                           (Y) if there shall exist any default  with respect to
                  the Subordinated  Debt other than a Payment Default (such debt
                  being a  "Non-monetary  Default"),  the Remedy Blockage Period
                  shall  remain in effect  until such default is cured or waived
                  by the holders of the Subordinated  Debt or the first date the
                  Senior  Obligations  are  no  longer  outstanding;   provided,
                  however,  that all Remedy  Blockage  Periods  pursuant to this
                  Section  3(b)(Y)  shall  terminate  and no further such Remedy
                  Blockage  Periods shall  commence  upon the  expiration of any
                  Remedy Blockage  Period which has expired  pursuant to Section
                  3(b)(X) hereof.

     (c)  Upon any distribution to creditors of the Borrower in a liquidation or
          dissolution  of  the  Borrower  or  in a  bankruptcy,  reorganization,
          insolvency,  receivership, or other similar proceeding with respect to
          the  Borrower  or any of its  property,  (i) the holders of the Senior
          Obligations  will be entitled to receive  payment in full in cash,  of
          all  amounts  payable  under or in  respect  of the Senor  Obligations
          (including interest accrued after the commencement of such proceeding)
          before  the  holders  of the  Subordinated  Debt will be  entitled  to
          receive  from the  Borrower  or its  assets  any  payment  under or in
          respect of the  Subordinated  Debt and (ii)  until the  holders of the
          Senior  Obligations  have received  such payment in full in cash,  any
          distribution  from the  Borrower or its assets to which the holders of
          the Subordinated Debt would otherwise be entitled is to be made to the
          holders  of the  Senior  Obligations  (or  one  or  more  trustees  or
          representatives acting on their behalf).  Subject to the prior payment
          in full in cash of all  Senior  Obligations  (or  provision  made  for
          payment in full in cash of all Senior Obligations), the holders of the
          Subordinated  Debt shall be subrogated to the rights of the holders of
          the Senior  Obligations to receive  payments or distribution of assets
          of the Borrower applicable to the Senior Obligations until all amounts
          owing on the Subordinated Debt shall be paid in full.

     (d)  The  Lender  (or a  trustee,  representative,  or agent  acting on its
          behalf)  will be obligated to hold in trust for the benefit of, and to
          directly and  immediately  pay over or deliver to, with any  necessary
          endorsement,  the  holders of the Senior  Obligations  (or one or more
          trustees,  representatives,  or  agents  acting on their  behalf)  all
          payments and distributions received by the Lender (i) in contravention
          of the restrictions contained in the preceding clauses (a) through (c)
          or (ii) as a result  of any lien in  violation  of clause  (e)  below;
          provided, however, that notwithstanding such restrictions,  the Lender
          shall be entitled to receive  and to retain any and all  payments  (i)
          made in securities of the Borrower  provided the same are subordinated
          to  the  Senior  Obligations  at  least  to  the  same  extent  as the
          Subordinated  Debt or (ii) made in accordance  with any relevant court
          order respecting the subordination provided for herein.

     (e)  The  Lender  will not  create,  assume,  or  suffer to exist any lien,
          security interest,  or assignment of collateral securing the repayment
          of  the  Subordinated   Debt  unless  the  foregoing  shall  be  fully
          subordinate to any lien, security interest, or assignment in favor of

<PAGE>

          the Senior  Creditor  which secures any of the Senior Debt. The Lender
          hereby  subordinates any and all of its liens,  security interests and
          assignments  of collateral  to all such  security  rights from time to
          time existing in favor of the Senior Creditor.

(f)      The  Lender  and the  Borrower  agree  to  execute  any  and all  other
         instruments  reasonably  requested  by the Senior  Creditor  to further
         evidence the  subordination of the Subordinated Debt to the Senior Debt
         as herein provided.

(g)       This  provisions  of this  Section 3 are  irrevocable  and the  Senior
          Creditor may,  without notice to any of the parties hereto and without
          impairing or releasing the  obligations of the Borrower and the Lender
          hereunder, (i) create Senior Debt by extending credit under the Credit
          Agreement;  (ii)  change  the terms of or  increase  the amount of the
          Senior  Debt  by   increasing,   extending,   rearranging,   amending,
          supplementing,  or otherwise  modifying  any  instrument  or agreement
          creating Senior Debt; (iii) sell, exchange, release, or otherwise deal
          with any  collateral  securing any Senior Debt;  (iv) release  anyone,
          including the Borrower or any guarantor,  liable in any manner for the
          payment or collection of any Senior Debt; (v) exercise or refrain from
          exercising  any rights  against the  Borrower  or any other  person or
          entity; and (vi) apply any sums received by any Senior Creditor,  from
          whatever source, to the payment of the Senior Debt.

(h)               (i)  The  Lender  will  cause  all  Subordinated  Debt  to  be
                  evidenced by a note, debenture,  instrument,  or other writing
                  evidencing the Subordinated Debt and will inscribe a statement
                  or legend  thereon  to the effect  that such note,  debenture,
                  instrument,  or other  writing is  subordinated  to the Senior
                  Debt in favor of the Senior  Creditor in the manner and to the
                  extent set forth in this Note.

         (ii)     The Lender shall not assign or otherwise transfer to any other
                  Person or entity any interest in the Subordinated  Debt unless
                  the  Lender  causes  the  assignee  or  other   transferee  to
                  acknowledge  to the  reasonable  satisfaction  of  the  Senior
                  Creditor  the   subordination  of  the  Subordinated  Debt  in
                  accordance with this Note.

(i)      The foregoing  provisions  will be enforceable  against the Lender,

          Credit  Agreement  are binding on  FemPartners,  the  Borrower and the
          Lender  for the  benefit  of the  Senior  Creditor  until such time as
          FemPartners  and the Senior  Creditor  (or in the instance of multiple
          financial  institutions in the same credit facility,  the lead bank or
          agent  lender,  as the case may be of the Senior  Creditor)  furnishes
          Borrower  and  Lender  with  written  revocation  of the then  current

                                    EXHIBIT A

                        Supplemental Terms and Provisions

         S-1.1 Until  payment in full of the Note and  performance  of all other
obligations of Borrower hereunder, unless Lender provides its written consent to
the contrary:

                  (a)  Existence  and  Compliance.  Borrower  will  maintain its
         corporate  existence in good standing,  will substantially  comply with
         all material laws, regulations and governmental requirements applicable
         to it or to any of its property,  business operations and transactions,
         and will provide Lender with copies of all  instruments  filed with the
         Delaware Secretary of State amending and/or renewing its certificate of
         incorporation.

                  (b)  Adverse  Conditions  or Events.  Borrower  will  promptly
         advise Lender in writing of any condition,  event or act which comes to
         its  attention  that would  reasonably  be expected to  materially  and
         adversely  affect  Borrower's  financial  condition or Lender's  rights
         under the Note or the Guaranty.

                  (c)  Taxes.  Borrower  will pay all  federal  and state  taxes
         relating  to the  employees,  payroll,  income  or  gross  receipts  of
         Borrower prior to the date on which any fine, penalty, interest or late
         charge may be added  thereto for  nonpayment  thereof  excluding  taxes
         being contested in good faith by appropriate proceedings and for which,
         if required by generally  accepted  accounting  practices  consistently
         applied, adequate reserves have been established.

                  (d)      Transfer of Assets.  Except in the  normal  course of
         its  business,  Borrower  will not sell, lease, assign, or otherwise
         dispose of or transfer all or substantially all of its assets.

                  (e)  Change  in  Ownership  or  Structure.  Borrower  will not
         dissolve or  liquidate,  become a party to any merger or  consolidation
         other  than  with  an  affiliate  of  Borrower  or   reorganize   as  a
         professional corporation.

                  (f) Violate Other Covenants. Borrower will not violate or fail
         to comply with any covenants or agreements  regarding  other debt which
         would,  with the  passage  of time or upon  demand  or both,  cause the
         maturity of any debt arising  under the Senior  Credit  Agreement to be
         accelerated.

         S-1.2 Events of Default.  If one or more of the following  events shall
occur and continue  after thirty (30) days' written  notice to Borrower (each an
"Event of  Default"),  all  outstanding  principal  plus unpaid  interest of the
Advance and any other indebtedness of Borrower to Lender shall  automatically be
due and payable  immediately and Lender shall have no further obligation to fund
under the Note unless and until all events of default have been cured or waived:

                  (a) Default shall be made in the payment of any installment of
         principal or interest upon the Note,  when due and payable,  whether at
         maturity or otherwise; or

<PAGE>

                  (b)      Default shall be made in the  performance  of any
         material  term,  covenant or agreement contained herein; or

                  (c) Any  representation  or warranty herein  contained in this
         Note or the  Guaranty  shall prove to have been untrue or  incorrect in
         any material respect when made; or

                  (d) Any final  judgment or judgments  for the payment of money
         in excess of $500,000 in the aggregate at any time outstanding shall be
         rendered  against  Borrower and the same shall not,  within thirty (30)
         days after the entry thereof, have been discharged or execution thereof
         stayed  or bonded  pending  appeal,  or shall not have been  discharged
         prior to the expiration of any such stay.

                  (e) Any bankruptcy case or dissolution  proceeding  shall have
         been commenced  against  FemPartners and such case or proceeding  shall
         remain undismissed or unstayed for sixty (60) days or more; or

                  (f) Borrower makes an assignment for the benefit of creditors,
         admits in writing  its  inability  to pay its debts  generally  as they
         become due, files a petition in bankruptcy, is adjudicated insolvent or
         bankrupt,  petitions or applies to any tribunal for any receiver or any
         trustee of Borrower or any substantial part of its property,  commences
         any action relating to Borrower under any reorganization,  arrangement,
         readjustment of debt,  dissolution or liquidation law or statute of any
         jurisdiction,  whether now or  hereafter in effect,  or any  bankruptcy
         case or  dissolution  proceeding  shall  have  been  commenced  against
         Borrower  and such  case or  proceeding  shall  remain  undismissed  or
         unstayed for sixty (60) days or more.

         S-1.3 Lender's Remedies. Upon the occurrence and during the continuance
of an Event of  Default,  Lender,  without  notice of any kind,  except  for any
notice required under this Note or the Guaranty, may, at Lender's option: (i) by
notice to  Borrower,  terminate  its  obligation  to fund any  unfunded  Advance
hereunder;  (ii) declare the Indebtedness,  in whole or in part, immediately due
and payable;  and/or (iii)  exercise any other rights and remedies  available to
Lender under the Note or the Guaranty or  applicable  law;  except that upon the
occurrence  of an Event of Default  described in  subsection  S-1.2(f),  all the
Indebtedness  shall  automatically be immediately due and payable,  and Lender's
obligation to fund Advances  hereunder shall  automatically  terminate,  without
notice  of any kind to  Borrower  or to  FemPartners,  or to any  other  person.
Borrower,  FemPartners and each guarantor, surety, and endorser of the Note, and
any and all other parties liable for the Indebtedness or any part thereof, waive
demand,  notice  of  intent  to  demand,  presentment  for  payment,  notice  of
nonpayment,  protest,  notice of protest,  grace, notice of dishonor,  notice of
intent to accelerate maturity, notice of acceleration of maturity, and diligence
in  collection.  Notwithstanding  anything  to  the  contrary  herein  or in the
Guaranty,  in the event of any Event of Default that is  occasioned  solely by a
default or breach under the Merger Agreement, Lender's remedy hereunder shall be
limited  to the remedy  set forth in clause  (i) of the first  sentence  in this
Section S-1.3.

         S-1.4  Participation  or Sale of Loan.  Lender  shall have the right to
sell the Note, or participation  interests in the Note to any direct or indirect
wholly owned  subsidiary of Lender.  Borrower  shall  execute,  acknowledge  and
deliver all instruments reasonably necessary to document the unpaid indebtedness
evidenced by the Note.  Lender shall have the right to disclose in confidence to
such subsidiary purchaser such financial  information  regarding Borrower as may
be  necessary   to  complete  any  sale  or  attempted   sale  of  the  Note  or
participations or attempted participations in the Advance.

         Re:      Syntera HealthCare Corporation ("Syntera")

Ladies and Gentlemen:

may be  amended  or  otherwise  modified  from  time to  time,  the  "Note")  of
FemPartners of Central Texas, Inc., a Delaware corporation ("Borrower"), payable

is issued to amend,  restate and replace the  Promissory  Note dated November 1,

FemPartners, Inc., a Delaware corporation ("FemPartners"), agrees that it:

         A.       shall provide Lender with audited  financial  statements on an
                  annual  basis  within one hundred  twenty (120) to one hundred
                  fifty (150) days after the close of a fiscal  year;  but in no
                  event  beyond  five  (5) days  after  such  audited  financial
                  statements  have been  prepared and are to be delivered to any
                  other lender of FemPartners;

         B.       shall NOT declare any dividend  (i) without  the prior consent
                  of the Lender which consent shall

                  not be unreasonably  withheld,  or (ii) unless required by an
                  existing agreement with the holders of the preferred stock of
                  FemPartners;

         C. shall  NOT  redeem  its  stock  for cash in an  amount  in excess of
          $250,000 during any calendar year, except (i)upon the prior consent of
          Lender, which consent shall not be unreasonably withheld,  (ii) as may
          be  required by an existing  agreement  with the holders of  preferred
          stock of FemPartners,  (iii) as may be required to settle  contractual
          or other  disputes  with any  physician  or  physician  group  under a
          management agreement directly or indirectly  affecting  FemPartners or
          any of its  subsidiaries,  or (iv) in connection  with the purchase of
          FemPartners stock from any departing or retiring physician whose had a
          physician  practice  prior to such  departure  or  retirement  under a
          management agreement directly or indirectly  involving  FemPartners or
          any of its subsidiaries.

Lender shall be entitled to rely on the covenants made by FemPartners  hereunder
for all purposes in connection with the Note.



                                                                Exhibit 10.86

                               GUARANTY AGREEMENT


         This Guaranty  Agreement dated as of August 31,  1999 (as amended or
otherwise modified from time to time, this "Guaranty") is by FemPartners,  Inc.,
a Delaware  corporation  ("Guarantor") in favor of American  Physicians  Service
Group, Inc., a Texas corporation ("Lender").

         WHEREAS,   (i)  Lender,   Syntera  HealthCare   Corporation,   a  Texas
corporation  ("Syntera"),  Guarantor and  FemPartners of Central Texas,  Inc., a
Delaware corporation and wholly-owned  subsidiary of Guarantor  ("Obligor") have
entered  into an  Agreement  and Plan of Merger of even  date  herewith  whereby
Syntera  is merging  with and into  Obligor  with  Obligor  being the  surviving
corporation,  (ii) certain debt owing to Lender from Syntera is evidenced by the
Promissory Note dated November 1, 1998, and is being contemporaneously  amended,
restated and replaced in its entirety by the  Replacement  Promissory Note dated
of even date herewith (as may be amended and or otherwise  modified from time to
time, the "Note"), (iii) Guarantor will directly and indirectly benefit from the
Note,  and (iv) as a condition  precedent to the  consummation  of the merger of
Syntera into Obligor, Lender has required that Guarantor guarantee to Lender all
payment obligations of Obligor under the Note.

         NOW THEREFORE, Guarantor agrees with Lender as follows:

         1.   PAYMENT   GUARANTY.   Guarantor   absolutely,    irrevocably   and
unconditionally  guarantees  to  Lender,  and  to  its  successors,   endorsees,
transferees and assigns,  the prompt and complete  payment when due,  whether at
the stated maturity, by acceleration or otherwise, of the obligations of Obligor
set forth in the Note (collectively,  the "Obligations").  No termination of the
Note shall affect any  obligations  incurred by Guarantor under this Guaranty at
the time of termination.  No notice of the Obligations need be given in any form
to Guarantor at any time and  Guarantor  waives any such notice and the right to
consent to the Obligations. Guarantor waives any right to require as a condition
to its obligations hereunder that collateral be applied to the Obligations, that
presentment  or demand be made upon  Obligor or that  action be brought  against
Obligor or any other person or entity  except  Guarantor,  should Lender seek to
enforce  the  obligations  of  Guarantor.   Specifically,   without  limitation,
Guarantor  waives any right to require  that a judgment  previously  be rendered
against Obligor or any other person or entity except Guarantor,  that Obligor or
any other person or entity be joined in any action against  Guarantor or that an
action  separate from one against  Guarantor be brought  against  Obligor or any
other person or entity.  The  obligations of Guarantor are several from those of
Obligor  or any other  person or entity,  and are  primary  payment  obligations
concerning which Guarantor is the principal  obligor.  If all or any part of the
Obligations are not paid when due,  Guarantor hereby guarantees that it will pay
the same to Lender,  upon demand,  without set-off or  counterclaim  and without
reduction by reason of any taxes,  levies,  imposts,  charges and  withholdings,
restrictions  or  conditions  of any  nature  that are now or may  hereafter  be
imposed,  levied or assessed by any  country,  political  subdivision  or taxing
authority,  all of which will be for the account of and paid by  Guarantor,  and
Lender need not first proceed to preserve, utilize or exhaust any other right or
remedy  against  Obligor,  any  other  guarantor,  any  collateral  or any other
security  that  Lender  may have in  order  to  obtain  payment  hereunder.  The
obligations  of Guarantor  hereunder  shall in no way be affected or impaired by
reason  of the  happening  from  time  to  time  of any  of the  following:  (i)
extensions  (whether  or not  material)  of the time for  payment  of all or any

<PAGE>

portion of the  Obligations,  (ii) the  modification  or amendment in any manner
(whether  or not  material)  of the Note or the  Obligations,  (iii)  except for
applicable statutes of limitations,  any failure,  delay or lack of diligence on
the part of Lender, or any other person or entity to enforce, assert or exercise
any right, privilege, power or remedy conferred on Lender or any other person or
entity in the Note or at law,  or any action on the part of Lender or such other
person  or  entity  granting  indulgence  or  extension  of any  kind,  (iv) the
settlement  or compromise of any  Obligations  and (v) the status,  composition,
structure or name of Obligor change, including, without limitation, by reason of
merger,  dissolution,  consolidation  or  reorganization.   NOTWITHSTANDING  THE
FOREGOING,  THE  LIABILITY  OF GUARANTOR  HEREUNDER  SHALL BE LIMITED TO DIRECT,
ACTUAL  DAMAGES  AND  GUARANTOR  SHALL NOT BE LIABLE  UNDER  THIS  GUARANTY  FOR
CONSEQUENTIAL, INCIDENTAL, PUNITIVE, EXEMPLARY OR INDIRECT DAMAGES, LOST PROFITS
OR OTHER BUSINESS INTERRUPTION DAMAGES, IN TORT, CONTRACT OR OTHERWISE.  Upon 30
Days written notice and with the prior written consent of Lender,  which consent
shall not be  unreasonably  withheld,  this  Guaranty  may be  replaced by (x) a
guaranty in  substantially  similar  form made by a guarantor of equal or better
creditworthiness  or (y) a letter of credit in favor of Lender in the  amount of
the maximum Limit (below defined), issued by a bank and in a form, each of which
shall be reasonably satisfactory to Lender.

         2.       COSTS AND  EXPENSES. In addition to its guarantee of Obligor's
payment of the  Obligations,  Guarantor  shall pay all actual costs and expenses
(including  reasonable attorney's fees) paid or incurred by Lender in connection
with the enforcement of this Guaranty.

         3. CONTINUING  GUARANTY.  This is intended to be and shall be construed
as a continuing guarantee and shall remain in full force and effect and shall be
binding in accordance with and to the extent of its terms upon Guarantor and its
successors  and  assigns,  and shall  inure to the  benefit of  Lender,  and its
successors,  endorsees,  transferees  and assigns.  The obligations of Guarantor
under this Guaranty  shall continue in full force and effect and shall remain in
operation until all of the Obligations shall have been paid in full or otherwise
fully satisfied, and continue to be effective or be reinstated,  as the case may
be, if at any time payment or other  satisfaction  of any of the  Obligations is
rescinded  or must  otherwise  be  restored  or  returned  upon the  bankruptcy,
insolvency,  or reorganization of Obligor, or otherwise,  as though such payment
had not been made or other satisfaction occurred. No invalidity, irregularity or
unenforceability  by reason of applicable  bankruptcy  laws or any other similar
law, or any law or order of any  government or government  agency  purporting to
reduce, amend or otherwise affect, the Obligations,  shall impair,  affect, be a
defense to or claim against the obligations of Guarantor under this Guaranty.

         4.  SUBROGATION.  Notwithstanding  any  payment  or  payments  made  by
Guarantor under this Guaranty or any setoff or application of funds of Guarantor
by Lender, Guarantor shall not be entitled to be subrogated to any of the rights
of Lender  against  Obligor or any  collateral or other security or guarantee or
right  of  offset  held  by  Lender  for  the  payment  or  performance  of  the
Obligations,  nor shall Guarantor seek any reimbursement from Obligor in respect
of payments made by Guarantor under this Guaranty,  until all amounts then owing
and any other performance then due to Lender by Obligor for or on account of the

<PAGE>

Obligations are paid and satisfied in full.  Upon such payment and  satisfaction
in full,  Guarantor  shall be subrogated to all rights of Lender against Obligor
or any  collateral  or other  security or  guarantee  or right of offset held by
Lender for the payment and performance of the Obligations.

         5. SUBORDINATION.  Any and all indebtedness of Obligor now or hereafter
owed to or held by Guarantor is hereby  subordinated  to the Obligations and all
other  indebtedness  of Obligor to Lender;  and such  indebtedness of Obligor to
Guarantor, if Lender so requests,  shall be collected,  enforced and received by
Guarantor  as  trustee  for  Lender and be paid over to Lender on account of the
indebtedness  of Obligor to Lender but  without  reducing  or  affecting  in any
manner the liability of Guarantor under the other provisions of this Guaranty.

         6. DEFAULT.  If Obligor fails or refuses to timely pay any Obligations,
Lender may at its option exercise any or all of its rights,  powers and remedies
afforded  hereunder and may declare the unpaid amounts of all  Obligations  then
owing under the Note to be  immediately  due and  payable,  and  thereupon  such
amounts shall be immediately due and payable without presentation and demand for
payment,  protest,  notice of protest or dishonor,  notice of default, notice of
intent to accelerate or notice of  acceleration to Guarantor or any other person
or entity, all of which Guarantor waives.

         7. NO WAIVER. No failure to exercise and no delay in exercising, on the
part of Lender,  any right, power or privilege under this Guaranty shall operate
as a waiver of the right,  power or  privilege,  nor shall any single or partial
exercise of any right, power or privilege preclude any other or further exercise
of the right,  power or privilege,  or the exercise of any other power or right.
The rights  and  remedies  provided  in this  Guaranty  are  cumulative  and not
exclusive of any rights or remedies provided by law.

         8. NOTICE.  All notices and  communications  made pursuant to this
Guaranty  shall be in writing and  delivered  personally  or mailed by certified
