            AMERICAN PHYSICIANS SERVICE GROUP, INC. AND SUBSIDIARIES

                           ANNUAL REPORT ON FORM 10-K

                   FOR THE FISCAL YEAR ENDED DECEMBER 31, 1998

                                     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.  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 (other than Prime Medical, Syntera and Uncommon Care).

INVESTMENT 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  60%,  44% and 32% of  Company  revenues  in 1998,  1997 and 1996,
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. 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 28, 1999, 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 34%, 48% and 57% of
Company revenues in 1998, 1997 and 1996, respectively.  Substantially all of the
revenue was attributable to American  Physicians  Insurance  Exchange ("APIE") a
reciprocal   insurance   exchange.   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  profit.  The  amount of these  premiums  can be  adversely  affected  by
competition.   Substantial   underwriting   losses,  which  might  result  in  a
curtailment  or cessation of operations  by APIE,  would also  adversely  affect
FMI's revenue. To limit possible  underwriting  losses, APIE currently reinsures
its risk in excess  of  $250,000  per  medical  incident.  APIE  offers  medical
professional liability insurance for doctors in Texas and Arkansas. FMI's assets
are not subject to any insurance claims by policyholders of APIE. Termination of
the agreement with APIE would have a material adverse effect on the Company.


                                       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  profit.  FMI pays all
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.

     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 has also
granted  FPIC an option,  exercisable  at any time during  1999,  to purchase an
additional 35% interest in Insurance Services from the Company for $4,146,000.

     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 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. APIE and Florida Physicians reinsure 100% of all Texas and Arkansas
coverage per medical incident between $250,000 and $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 1998,  1997, 1996, 1995, and 1994,
management  fees  attributable  to profit sharing were  $1,750,000,  $1,961,000,
$1,191,000, $700,000, and $1,107,000, respectively.

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
affiliates. The remainder is leased to unaffiliated parties.

OTHER INVESTMENTS

     The  Company  owns  3,064,000  shares  of  common  stock of  Prime  Medical
Services,  Inc. ("Prime Medical"),  representing at March 15, 1999 approximately
18% of the  outstanding  shares of common stock of Prime  Medical.  Two of Prime
Medical's  seven  directors  are members of the  Company's  four member board of
directors.  The Company records its pro-rata share of Prime Medical's results on
the equity basis. Prime Medical is the largest provider of lithotripsy  services
in the United States, currently servicing over 450 hospitals and surgery centers
in 34 states.  Lithotripsy  is a non-invasive  method of treating  kidney stones
through the use of shock waves.  The common stock of Prime  Medical is traded on
the NASDAQ National Market under the symbol "PMSI".  Prime Medical is a Delaware
corporation  which is required to file annual,  quarterly  and other reports and
documents with the Securities and Exchange Commission (the "SEC"), which reports
and documents contain  financial and other information  regarding Prime Medical.
The summary information regarding Prime Medical contained herein is qualified in
its  entirety by  reference  to such  reports and  documents.  Such  reports and
documents  may be examined  and copies may be  obtained  from the offices of the
SEC.

     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 a $2,400,000  line of credit.  The
loan is at ten percent  interest,  payable  quarterly  until January 1, 2003, 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.

     On October 1, 1997, the Company formed APS Practice Management, Inc., later
renamed Syntera HealthCare Corporation  ("Syntera") with an initial ownership of
85%.  Syntera  specializes  in the  management  of OB/GYN  and  related  medical
practices. In a typical transaction,  Syntera acquires the non-medical assets of
a physician's practice, signs 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 is paid a variable
management  fee that rewards the  efficient  operation  and the expansion of the
practice.  Medical  services  are not  provided  by  Syntera.  All of  Syntera's
directors  are  officers  of the  Company.  The Company  expects  its  ownership
interest in 


                                       5
<PAGE>

Syntera (62% as of March 15, 1999) to be reduced to a minority  level as Syntera
exchanges its stock for assets of  additional  physician  practices.  Due to the
short time frame  anticipated for this change in ownership to occur, the Company
has accounted for its ownership in Syntera on the equity basis.

     On October 31, 1996, the Company invested $3,300,000 in the common stock of
Consolidated Eco-Systems,  Inc. (formerly Exsorbet Industries, Inc.) ("Con-Eco")
(NASDAQ:EXSO)  with a put option.  Con-Eco is a  diversified  environmental  and
technical services company.  On November 26, 1996, the Company exercised its put
in exchange for a promissory note from Con-Eco.  The promissory note was secured
by the  shares  which  were  subject  to the  put  plus  all  of the  stock  and
substantially all of the assets of a wholly-owned  subsidiary of Con-Eco and the
guarantees of all operating  subsidiaries of Con-Eco.  The Company  renegotiated
the debt with Con-Eco in November 1997. In connection  with the  renegotiations,
the  Company  extended  the debt for two years  and  refinanced  unpaid  accrued
interest,  resulting in a new promissory note for $3,788,000. No interest income
has been recognized by the Company.  Con-Eco provided  additional  collateral to
the Company in the form of stock of two  additional  subsidiaries,  and a second
lien on all  assets  of one of  these  subsidiaries.  The  Company  subsequently
declared  Con-Eco in default under the new promissory note and related  security
agreements.   In  March,   1999  the  Company   entered  into  a   comprehensive
Restructuring  Agreement  pursuant to which the Company retained its interest in
all of its existing  collateral,  obtained additional  collateral in the form of
stock of two more of Con-Eco's  subsidiaries  and obtained the highest  priority
security  interest  available in the assets of such  subsidiaries as well as the
assets of a third  subsidiary.  Under the Restructuring  Agreement,  the Company
agreed to refinance the existing  obligations of Con-Eco on more favorable terms
in the future,  provided the Company  receives  certain  minimum  payments  from
Con-Eco or from the  operations  of a subsidiary of Con-Eco that may be acquired
by the Company  through the enforcement of its security  interest.  Con-Eco also
agreed to make  specified  minimum  payments to the Company  upon the  favorable
resolution by Con-Eco of certain existing litigation or upon the sale of Con-Eco
or of Con-Eco's  or its  subsidiaries'  assets.  The Company has  established  a
reserve of $392,000  related to the principal  amount of the Con-Eco  receivable
and has  reserved  all  accrued  but unpaid  interest  related to the note.  The
Company may be required to establish additional reserves in the future depending
on the Company's ongoing evaluation of its collateral position and its estimates
of Con-Eco's future cash flows.

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 has 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 commission dollars
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 and other service
and claims settlement philosophy.

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.

     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.


                                       7

     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 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.

EMPLOYEES

     At March 1, 1999, the Company employed, on a full time basis, approximately
112 persons,  including 49 by Insurance Services, 46 by APS Financial,  4 by APS
Systems and 13 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.

ITEM 2.  PROPERTIES

     APS Realty owns approximately 53,000 square feet of condominium space in an
office project in Austin,  Texas.  The Company,  its subsidiaries and affiliates
use approximately  31,000 square feet of this space as their principal executive
offices,  and APS  Realty  leases  the  remainder  to  third  parties.  The area
available for lease to third parties is  approximately  90% occupied as of March
24, 1999.  The lease of the largest  third party tenant,  (11,000  square feet),
expires in April 1999 and it is unknown  how long will be required to re-let the
space.

ITEM 3.  LEGAL PROCEEDINGS

     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.

    ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
                      RESULTS OF OPERATIONS OF THE COMPANY

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

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.

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


                                       11
<PAGE>

second  office,  which  opened  in  1997.  Revenues  at  this  office  increased
approximately 90% over 1997.

     Investment  services' expenses increased 71% from 1997. 94% of the increase
was at the broker/dealer and was 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.

     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 a competitive  business and the
Company cannot say with certainty when or if it will achieve profitability.

Insurance Services

     Insurance  Service's  revenues  decreased 10% in 1998 compared to 1997. The
loss of a large  client by the  managed  insurance  company  caused  most of the
variance.  The client  purchased  extended  reporting period or "tail" coverage,
which increased  premiums in 1997.  1998 was lower by both the standard  premium
and the extra tail  premium.  The  Company's  premium-based  management  fee was
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 in
the  area  of  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.


                                       12
<PAGE>

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 has two  affiliates  accounted for on the equity  basis,  Prime
Medical Services,  Inc. and Syntera  HealthCare  Corporation.  Prime'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%.  The  Company,   through  its  status  as  Prime's  largest
shareholder and through its  representation on Prime's board,  continues to have
significant  influence at Prime and accounts for its investment using the equity
method.

1997 Compared to 1996

     Revenues from continuing operations increased 25% in 1997 compared to 1996.
Net income  increased  32% and diluted  earnings  per share  increased  28%. The
reasons for these changes are described below.

INVESTMENT SERVICES

     Investment  Services'  revenues  increased  73% in 1997  compared  to 1996.
Approximately   71%  of  the  increase  was   attributable   to  expanding   the
broker/dealer sales force with the opening of an additional office location. The
balance of the increase was primarily a result of lower  interest rates creating
more activity in the bond market.


                                       13
<PAGE>

     Investment  Services'  expenses  increased  38%  from  1996.  The  increase
reflects  increased  sales and expanded office  operations at the  broker/dealer
with the resultant  higher  commissions and payroll  expense.  Better control of
legal costs and a lower  allocation of corporate  overhead  partially offset the
increases.

INSURANCE SERVICES

     Revenues increased  6% as a result of a higher  contingent  fee,  which was
based on improved  profits at the  managed  insurance company.

     Expenses decreased 11% from 1996.  Decreases in legal and professional fees
and lower allocated  corporate  overhead were the  significant  areas of expense
reduction.

REAL ESTATE

     Revenue  decreased 2% compared to 1996. The small decrease reflects greater
utilization of the office building by the Company and affiliates at lower rental
rates than outside tenants.

     The 3% decrease in real estate  expenses in 1997 reflects  lower  corporate
overhead allocations.

INVESTMENT AND OTHER

     The  decline in  investment  and other  income was  primarily  due to lower
interest income,  the result of the Con-Eco note receivable being on non-accrual
during all of 1997.

GENERAL AND ADMINISTRATIVE EXPENSES

     The 800%  increase  in  expenses  was a result  of  changes  in  accounting
estimates  rather  than  fundamental  changes  in  operations.  1996's  expenses
reflected  favorable  adjustments  to  a  contingency  provision  related  to  a
guarantee, as well as favorable adjustments to allowances for doubtful accounts,
a result of collecting the accounts. No such adjustments were required in 1997.

     Interest  expense  declined 61%  primarily  due to paying off the Company's
real estate loan early in 1997.

AFFILIATES

     Earnings  from  affiliates  increased  43% compared to 1996.  Prime Medical
continued  to grow and did not have the  substantial  offering  and  acquisition
expenses it incurred in 1996. As a result, the Company's equity in earnings grew
67% in 1997. Partially offsetting this increase was a loss in equity earnings of
Syntera.  Syntera was  established  in 1997 and the loss  reflects  start-up and
development costs incurred in this early phase.

LIQUIDITY AND CAPITAL RESOURCES

     Net working  capital was $503,000 and  $3,360,000  at December 31, 1998 and
1997, respectively.  The decrease in working capital reflects the Company's cash
investment  of  approximately  $2,000,000 in new business  opportunities  during
1998. Also reducing working capital was the reclassification of short-term notes
receivable to long-term upon the maker's default on the notes. 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 1998, the Company entered into a three year $10,000,000 revolving credit
agreement  with  NationsBank  of Texas,  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. No funds had been advanced as of December 31, 1998.
At March 25, 1999 $1,600,000 had been advanced.

     Capital expenditures for equipment were $148,000,  $312,000,  and $123,000,
in 1998, 1997, and 1996, respectively.  In addition, the Company improved office
space in 1998 and  1996 for  $58,000  and  $21,000,  respectively.  The  Company
expects  capital  expenditures in 1999 to be within the range of the prior three
years.

     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.

YEAR 2000 PROJECT

The Company  formed a Year 2000 Committee in mid 1998. The Committee was charged
with  examining  (1)  internal  hardware  and  software  systems;  (2)  physical
facilities;  and (3)  outside  suppliers,  as these  items  relate to  potential
problems that could be caused by the inability to process dates beyond  December
31, 1999.

The  Committee  divided  its task  into  four  parts -  assessment,  remediation
planning,  implementation and testing and contingency  planning.  Assessment and
remediation  planning  have been  completed for all three phases of the project.
Implementation and testing and contingency planning are discussed below.

Internal hardware and software systems: The Company has completed  substantially
all of the needed  upgrades  to its  hardware  and  software  systems.  Software
testing is expected to be  complete  by April 30,  1999 and  remaining  hardware
purchases are expected to be complete by June 30, 1999.

 Physical facilities: The Committee has evaluated its non-computer equipment and
has determined that, except for its telephone system, there are no devices whose
failure  would  materially  affect the ability to carry out the  business of the
Company.  A compliant  telephone  system is expected to be installed by June 30,
1999. The outside  managers of the Company's office buildings have reported that
all aspects of the physical  facilities - elevators,  fire and security systems,
etc. are compliant.  Their further inquiry of those supplying  public  utilities
have produced assurances of best efforts but no guarantee of performance.

Outside  suppliers:  The  Company  has  inquired  about  the  state of Year 2000
readiness of those outside  suppliers who were  determined to be critical to the
Company's  ability to carry out its  business.  One  services  supplier has been
identified  as  being  behind  in its  readiness.  The  services  are  not of an
exclusive nature and alternative  suppliers are being evaluated.  A switch to an
alternative  would be made on September 1, 1999 if the current  supplier remains
non-compliant.

Contingency  planning:  The Company cannot be certain that it has identified and
will be successful in bringing into  compliance  all Year 2000 issues within its
control.  It can be even less  certain of critical  services  being  supplied by
third parties  beyond its control.  Upon  completion of the testing phase of the
plan, the Company will formalize plans for carrying on its business in the event
of unanticipated  Year 2000-related  failures.  Presently,  the Company believes
that the most  reasonably  likely  worst  case  scenario  would be a failure  of
relatively  short duration of basic third party services such as the power grid.
With such a failure the Company's  planning will be directed  toward a temporary
suspension  of  operations  followed  by  plans  for  resumption  and  catch  up
operations.  Due to the  magnitude  of the  uncertainties  related  to Year 2000
issues,  the  Company is unable to fully  assess the  consequences  of Year 2000
failures  and,  consequently,  there could be a material  adverse  effect on the
Company's results of operations, financial position and cash flows.

Year 2000 costs: The Company  estimates that total  expenditures to address Year
2000 issues will be $350,000, of which approximately 60% will be for capitalized
hardware  purchases.   The  remainder  of  the  expenditures  are  labor  costs.
Approximately  40% of the expenditures have been 


                                       16
<PAGE>

made to  date.  Since  the  Company  is in a  constant  state of  upgrading  its
technology  and since all labor costs involve  existing in- house staff,  few of
the costs incurred are incremental.  Extensive use of in-house MIS personnel for
Year 2000 issues has delayed  implementation  of other work  designed to improve
user  productivity and the value of information  provided.  The Company does not
believe  such  delays  will have a  material  adverse  effect on the  results of
operations, financial position, or cash flows.

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 1998  the  inventory
balance was  $535,000.  Historically,  the  Company  has turned  this  inventory
rapidly and has neither significant realized gains nor losses.

     The Company has notes receivable, the largest of which is described in Item
1 and is  currently  in  default.  The  fair  value  of this  defaulted  note is
determined by collateral  and cash flows of the maker and is influenced  little,
if any, by interest rate changes.  The other notes receivable are in the form of
lines of credit to  related  companies  and are at fixed 10%  rates.  Their fair
value will increase and decrease inversely with interest rates.

     The Company had no debt at December 31, 1998, but has a $10 million line of
credit  with a floating  interest  rate.  For each $1 million  that the  Company
should  borrow in 1999,  a 1 1/2 % increase in interest  rate would  result in a
$15,000 annual increase in interest expense.

                          Independent Auditors' Report





         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.

         In our opinion, the consolidated financial statements referred to above
         present fairly,  in all material  respects,  the financial  position of
         American  Physicians  Service Group,  Inc. and subsidiaries at December
         31, 1998 and 1997,  and the results of their  operations and their cash
         flows for each of the years in the three-year period ended December 31,
         1998, in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                        December 31, 1998, 1997 and 1996


(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  47% of total  revenues and
         insurance services generated 45%.

         American  Physicians  Services Group,  Inc. has two  affiliates;  Prime
         Medical Services, Inc., of which it owns approximately 18%, and Syntera
         HealthCare  Corporation,  of which  it owns  approximately  62%.  Prime
         Medical is the country's largest provider of lithotripsy  (non-invasive
         kidney stone fracturing)  services and Syntera is a physician  practice
         management  company.  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"), except for its investment in Syntera. Syntera is
         accounted  for using  the  equity  method,  as the  operating  plan for
         Syntera  will result in the Company  diluting  its  ownership  to a non
         controlling  position as additional  physician  practices are acquired.
         Investments  in affiliated  companies  and other  entities in which the
         Company's investment is less than 50% of the common

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                        December 31, 1998, 1997 and 1996


(1)      Summary of Significant Accounting Policies, continued

         shares outstanding and where the Company exerts  significant  influence
         are accounted for by the equity method.

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

(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.

         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

                  Trading securities                Fair value, unrealized 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
                                                    of   applicable    income

                        December 31, 1998, 1997 and 1996



(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)      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.

(i)      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.

(j)      Cash and Cash Equivalents

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

(1)      Summary of Significant Accounting Policies, continued

(k)      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.

(l)      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.

(m)      Reclassification

         Certain  reclassifications  have  been  made to  amounts  presented  in
         previous years to be consistent with the 1998 presentation.

(n)      Other Comprehensive Income

          For the three years ended December 31, 1998, the Company has not had
          any significant other comprehensive income

the prime rate. The borrower  defaulted in 1998 and the Company is in litigation
to
collect amounts owed.                                                                       $156,000          176,000

(3)      Notes Receivable, continued

         The Company's  note  receivable  from  Consolidated  Eco-Systems,  Inc.
         (formerly  Exsorbet  Industries,  Inc.)  ("Con-Eco")  (NASDAQ:EXSO),  a
         diversified  environmental and technical services company, is in excess
         of 10% of  stockholder's  equity at December 31, 1998 and  represents a
         concentration of credit risk. No interest income has been recognized by
         the Company.

         Following  a  renegotiation  of the  debt  in  November  1997,  Con-Eco
         defaulted on the note. Con-Eco's stock was delisted during 1998 and has
         negligible value. The Company considers the loan to be impaired and has
         recorded the loan as follows:

(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, 1998 and 1997.

         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.

(4)      Fair Value of Financial Instruments, continued

         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.

         Preferred Stock Investment

         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.

(4)      Fair Value of Financial Instruments, continued

         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
         equipment, investment in affiliates, other assets, accrued expenses and
         income tax payable. In addition,  the tax ramifications  related to the
         realization of the  unrealized  gains and losses can have a significant
         effect on fair  value  estimates  and have not been  considered  in the
         aforementioned estimates.

(5)      Property and Equipment

         Property and equipment consists of the following:

(7)      Notes Payable

         The  Company  has  established  a  $10,000,000   line  of  credit  with
         NationsBank  of Texas,  N. A. The Company  will pledge  shares of Prime
         Medical to the bank as funds are advanced  under the line. No funds had
         been advanced at December 31, 1998.  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.

(8)      Commitments and Contingencies

         The  Company  has  extended  a line of  credit  to  Syntera  HealthCare
         Corporation  to a maximum  amount of  $3,000,000.  The note is interest
         only at 10%, payable  quarterly.  The note matures November 1, 2001, at
         which time all  principal  and  accrued  but unpaid  interest  are due.
         Advances  under  the  line  are  subject  to  Syntera  meeting  certain
         qualifications at the date of each advance request.

         The Company has extended a line of credit to Uncommon  Care,  Inc. 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.  Advances  under the line are
         subject to Uncommon Care meeting certain  qualifications at the date of
         each advance request.

         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 has  guaranteed  a loan in the amount of $85,000 for one of
         its  directors.  The  guarantee is  collateralized  by  securities  the
         Company believes sufficient to cover its potential liability.

         Rent expense  under all operating  leases for the years ended  December
         31, 1998, 1997 and 1996 was $44,000,  $89,000 and $51,000 respectively.
         Future minimum  payments for leases which extend for more than one year
         were $96,000 at December 31, 1998.

         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.

         The  valuation  allowance for deferred tax assets as of January 1, 1997
         was $0. The net change in the total  valuation  allowance for the years
         ended December 31, 1998 and 1997 was a (decrease)/increase  of ($2,000)
         and  $188,000,  respectively.  The Company  believes that the valuation
         allowance  at  December  31,  1998 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, 1998,  net operating  loss  carryforwards  available to
         reduce future taxable  income  amounted to  approximately  $548,000 and
         expire from years 2011 to 2012.

         Based upon the level of historical  taxable income and  projections for
         future  taxable  income over the periods  which the deferred tax assets
         are  deductible,  management  believes  it is more  likely than not the
         Company will realize the benefits of these deductible differences,  net
         of the existing valuation allowances at December 31, 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
         1998) 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,  1998,  1997  and  1996,
         contributions  by  the  Company  aggregated,   $126,000,   $92,000  and
         $104,000, 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 issued.  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.

         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 1998, 1997 or 1996. 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
         indicated below:

        Expected dividend yield         -0-            -0-             -0-


    Statement  123  calls for a  prospective  application  of  compensation
    relating  to the grant of stock  options  and,  consequently  pro-forma
    financial information may not be indicative of future amounts until the
    new rules are applied to all outstanding non-vested awards.

    Presented below is a summary of the stock options held by the Company's
    employees  and  directors  and the related  transactions  for the years
    ended December 31, 1998, 1997 and 1996.  Remaining options  outstanding

(12)     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  originally  assumed  that all clients  would have  migrated to
         other  software  products by the end of 1999 and reflected the expected
         financial impact of discontinuing this segment on that date in the 1997
         financial  statements.  The measurement  date for determining  expected
         losses from the disposal was May 15, 1997.  Termination  of support for
         one  client,  whose  contract  runs until  2002,  may now  extend  past
         December  31,  1999.  Consequently,  the Company has  adjusted its loss
         allowance  and  believes  that  such  allowance  is  adequate  to cover
         potential future obligations.

(13)     Investments in Affiliates

         On October 12, 1989, the Company  purchased for cash  3,540,000  shares
         (42%) of the  common  stock of Prime  Medical  Services,  Inc.  ("Prime
         Medical"). Members of the Company's Board currently serve as two of the
         seven directors of Prime Medical.  Prime Medical  provides  non-medical
         management  services to lithotripsy  centers.  In conjunction  with the
         acquisition of additional  lithotripsy operations in June 1992, October
         1993, and May 1996, the outstanding  shares of Prime Medical increased.
         These increases,  the sale of Prime Medical shares owned by the Company
         under an option  agreement,  and the repurchase by Prime Medical of its
         own shares, in the aggregate,  have reduced the Company's  ownership to
         18% of the  outstanding  common stock of Prime  Medical.  The Company's
         investment in Prime  Medical is accounted for using the equity  method.
         The 3,064,000  shares of Prime Medical common stock held by the Company
         had an  approximate  market value of  $22,409,000  (carrying  amount of
         $13,089,000)  at December 31, 1998 based on the market closing price of
         $7.3125 per share.

         On October 1, 1997, the Company formed Syntera  HealthCare  Corporation
         ("Syntera") with an initial  ownership of 85%.  Syntera  specializes in
         the management of OB/GYN and related  medical  practices.  In a typical
         transaction,  Syntera acquires the non-medical  assets of a physician's
         practice,  signs a long-term  management contract with the physician to
         provide all of the non-medical requirements of the practice,  including
         personnel,  office space, billing and collection,  and other day-to-day
         operating functions. In turn, Syntera is paid a variable management fee
         that rewards the efficient operation and the expansion of the practice.
         The  Company  expects  to reduce  its  ownership  (currently  62%) to a
         minority level as it exchanges  stock for practice  assets.  Due to the
         short time frame anticipated for this change in ownership to occur, the
         Company has accounted for its ownership on the equity basis in 1998 and
         1997.

                  STATEMENTS December 31, 1998, 1997 and 1996


(14)     Segment Information, continued

         At December 31, 1998 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)     Earning 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:

         At  December  31, 1998 the  Company's  affiliate,  Syntera,  had issued
         620,000  shares which are  convertible  into  724,000 of the  Company's
         common  shares in the event that the  Syntera  shares are not  publicly
         tradable  after a future date.  Such  conversion  rights are in varying
         amounts beginning in October 1999 and extending through January 2002.

Unexercised  employee  stock  options to purchase  295,000,  295,000 and 244,000
shares of the  Company's  common stock as of December  31, 1998,  1997 and 1996,
respectively,  were not included in the  computations of diluted EPS because the
options'  exercise  prices were  greater  than the average  market  price of the
Company's common stock.

acknowledged, the parties hereto agree as follows:

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

                  (a) There  shall  not have  been,  on or before  two (2) years
following the date hereof (the  "Determination  Date"),  any  registered  public
offering of the common stock of Practice Management, or any other transaction or
event  pursuant to which shares of Practice  Management of the same class as the
PM Shares shall have become publicly traded.; 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 Practice  Management  and/or APS are parties,  and  Shareholder
shall not have threatened to breach or default under this Agreement,  any of the
Acquisition Documents or any such other contract or agreement; 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 

                                       2
<PAGE>

PM Shares, and the PM Shares are free of any
and all liens, claims or encumbrances of any kind whatsoever; and

                  (d) At or before the Closing Date,  Practice  Management shall
not  be,  or  have  been,  a  party  to any  merger,  consolidation  or  similar
transaction,  or agreement  with  respect  thereto,  pursuant to which  Practice
Management  was not or would  not be,  the named  surviving  entity  after  such
merger, consolidation or other transaction.

         2. 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 PM  Shares  for  shares  of APS  Common,
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.

         3.       SHARE CONVERSION.

                  (a)  Shareholder's  right to exchange its PM Shares  hereunder
shall  apply as to all,  but not less  than  all,  of the PM  Shares  which  are
eligible for exchange as described in this  paragraph (a) of Section 3. Assuming
Shareholder  has complied  with all of the  conditions  allowing for an exchange
pursuant  to this  Agreement,  55,000 of the PM  Shares  shall be  eligible  for
conversion as provided in this Agreement; and the remaining 20,000 PM 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  the
Determination  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 Determination 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  Determination  Date, then no portion of the 20,000 PM
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  Determination  Date,  the Clinic PAE  exceeds  $450,000,  then the
percentage of the 20,000 PM 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  20,000 by a fraction,  the
numerator of which is the amount by which Clinic PAE exceeds  $400,000  (but not
greater than $100,000 in any event), and the denominator of which is $100,000.

                                       4
<PAGE>


         EXAMPLE:  The following is provided  purely by way of example only, and
illustrates  the  calculation  of the number of PM 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 $450,000 for the 12 months ended December
                  31,  1998,  which is the  largest  twelve  (12) month level of
                  Clinic PAE  achieved  in any  period  ended on or prior to the
                  Determination Date.

                  Total PM  Shares  eligible  for  exchange  hereunder  would be
                  65,000 determined as follows:

                  $450,000 - $400,000    x     20,000         =        10,000
                  -------------------
                       $100,000                                        55,000
                                                                       ------
                                                                       65,000

         (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 Expiration Date. The maximum number of
PM Shares which  Shareholder has the right to exchange pursuant to paragraph (a)
of this Section are hereinafter referred to as the "Exchangeable PM Shares"; and
the "Gross  Exchange  Value" for purposes of this  Agreement is the gross dollar
amount  determined by  multiplying  the  Exchangeable  PM Shares by the Exchange
Value.  For purposes of determining the number of shares of APS Common which may
be  received  upon  any  exchange,  no  consideration  will be  given  to  stock
dividends,  stock  splits,  reverse stock splits or  recapitalizations  to which
Practice  

                                       5
<PAGE>

Management or the PM Shares are subject after the date this  Agreement
was originally entered into as first above written. At the Closing,  Shareholder
shall be  entitled  to receive  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.

         (c) At the Closing,  Shareholder shall tender its share  certificate(s)
for all of the Exchangeable PM 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 PM Shares and that the Exchangeable PM
Shares  are  being  transferred  to APS free and clear of all  liens,  claims or
encumbrances of any kind  whatsoever.  The shares of APS Common that Shareholder
receives in the  exchange are  hereinafter  referred to as the "New APS Shares."
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  conversion  calculation  shall be rounded up or down, as the
case  may be,  to the  next  whole  number  of  shares.  APS  shall  be under no
obligation to pay any cash or other amounts with respect to any fractional share
amounts,  or to issue  any  fractional  share  amounts  to  Shareholder.  At the
Closing,  Shareholder  shall either receive a share  certificate for all its New
APS Shares or, if APS' transfer  agent is unable to produce such  certificate by
the Closing  Date,  will receive a copy of a registered  letter sent from 

                                       6
<PAGE>

APS to the transfer agent instructing the transfer agent to deliver such 
certificate in the name of Shareholder directly to Shareholder or Shareholder's
designee.

         4. NEW APS SHARES TRANSFERABILITY. APS will have registered the New APS
Shares with the Securities and Exchange Commission,  and made such other filings
and taken such other steps as necessary,  so that  Shareholder  may  immediately
sell, or otherwise  convey,  the New APS Shares 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 the
New APS Shares for such period of time (not to exceed one hundred  eighty  (180)
days) as may be requested by such lead underwriter.

         5.       Miscellaneous.

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

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

                            SHARE EXCHANGE AGREEMENT


         This Share Exchange  Agreement  (this  "Agreement") is made and entered
into  as of the 1st day of  April,  1998,  by and  between  American  Physicians
Service Group, Inc., a Texas corporation ("APS") and Antonio Cavazos,  Jr., 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")  entered into by Shareholder of even date herewith and
the other  contracts and  agreements to which  Shareholder  was, or was to be, 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 has acquired or will acquire 30,276 shares
(the "PM Shares") of the $0.001 par value per share common stock of APS Practice
Management, Inc., a Texas corporation ("Practice Management"); and

         WHEREAS,  APS has agreed,  on the terms and  subject to the  conditions
hereof, to exchange certain shares of its $0.10 par value per share common stock
("APS Common") for the PM Shares.

         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:
<PAGE>

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

                  (a) There  shall not have been,  on or before  March 31,  2000
(the  "Determination  Date"), any registered public offering of the common stock
of Practice  Management,  or any other  transaction  or event  pursuant to which
shares of  Practice  Management  of the same  class as the PM Shares  shall have
become publicly traded; 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 Practice  Management  and/or APS are parties,  and  Shareholder
shall not have threatened to breach or default under this Agreement,  any of the
Acquisition Documents or any such other contract or agreement; 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 PM Shares, and the PM Shares are free of any
and all liens, claims or encumbrances of any kind whatsoever; and

                                       2
<PAGE>

                  (d) At or before the Closing Date,  Practice  Management shall
not  be,  or  have  been,  a  party  to any  merger,  consolidation  or  similar
transaction,  or agreement  with  respect  thereto,  pursuant to which  Practice
Management  was not or would  not be,  the named  surviving  entity  after  such
merger, consolidation or other transaction.

         2. 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 PM  Shares  for  shares  of APS  Common,
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.

         3. SHARE  CONVERSION.  Shareholder's  right to  exchange  its PM Shares
hereunder shall apply as to all, but not less than all, of the PM Shares. 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 

                                       3
<PAGE>

Expiration Date. For purposes hereof,  any additional
shares of  Practice  Management  stock of any class  which  Shareholder  obtains
pursuant  to  stock   dividends,   stock   splits,   reverse   stock  splits  or
recapitalizations  to which  Practice  Management  or the PM Shares are  subject
after the date this Agreement was originally entered into as first written above
shall also be considered to be included in the PM Shares; however, no adjustment
or  modification  will be made to the per  share  price  hereunder  of  Practice
Management  stock  as  a  result  of  any  such  transaction.  At  the  Closing,
Shareholder  shall be  entitled  to  receive  such  shares  of APS  Common as is
determined by dividing $5.00 per share (the "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.

         At the Closing,  Shareholder shall tender its share  certificate(s) for
all of the PM 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 PM Shares and that the PM Shares are being transferred to APS free
and clear of all liens, claims or encumbrances of any kind whatsoever.

         The shares of APS Common that Shareholder  receives in the exchange are
hereinafter  referred to as the "New APS  Shares." The parties  acknowledge  and
agree  that  Shareholder  shall  receive a whole  number of shares of APS Common
only,  and  that any  fractional  share  amounts  

                                       4
<PAGE>

resulting  from the  foregoing
conversion  calculation  shall be rounded up or down, as the case may be, to the
next whole number of shares. APS shall be under no obligation to pay any cash or
other  amounts with respect to any  fractional  share  amounts,  or to issue any
fractional  share  amounts to  Shareholder.  At the Closing,  Shareholder  shall
either  receive  a share  certificate  for all its New APS  Shares  or,  if APS'
transfer agent is unable to produce such  certificate 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  in the name of
Shareholder directly to Shareholder or Shareholder's designee.

         4. NEW APS SHARES  TRANSFERABILITY.  APS will have  registered,  at its
expense,  the New APS Shares with the  Securities and Exchange  Commission,  and
made such  other  filings  and taken  such  other  steps as  necessary,  so that
Shareholder  may  immediately  sell,  or  otherwise  convey,  the New APS Shares
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

                                       5
<PAGE>

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 the New APS
Shares for such period of time (not to exceed one hundred  eighty (180) days) as
may be requested by such lead underwriter.

         5.       MISCELLANEOUS.

                  (a) FEES AND EXPENSES.  Except as otherwise  herein  provided,
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

                            SHARE EXCHANGE AGREEMENT


         This Share Exchange  Agreement  (this  "Agreement") is made and entered
into  as of the 1st day of  April,  1998,  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") entered into by Shareholder of even date herewith and the
other contracts and agreements to which  Shareholder  was, or was to be, 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 has acquired or will acquire 70,000 shares
(the "PM Shares") of the $0.001 par value per share common stock of APS Practice
Management, Inc., a Texas corporation ("Practice Management"); and

         WHEREAS,  APS has agreed,  on the terms and  subject to the  conditions
hereof, to exchange certain shares of its $0.10 par value per share common stock
("APS Common") for the PM Shares.


<PAGE>



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

                  (a) There  shall not have been,  on or before  March 31,  2000
(the  "Determination  Date"), any registered public offering of the common stock
of Practice  Management,  or any other  transaction  or event  pursuant to which
shares of  Practice  Management  of the same  class as the PM Shares  shall have
become publicly traded.; 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 Practice  Management  and/or APS are parties,  and  Shareholder
shall not have threatened to breach or default under this Agreement,  any of the
Acquisition Documents or any such other contract or agreement; 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 

                                       2
<PAGE>

PM Shares, and the PM Shares are free of any
and all liens, claims or encumbrances of any kind whatsoever; and

                  (d) At or before the Closing Date,  Practice  Management shall
not  be,  or  have  been,  a  party  to any  merger,  consolidation  or  similar
transaction,  or agreement  with  respect  thereto,  pursuant to which  Practice
Management  was not or would  not be,  the named  surviving  entity  after  such
merger, consolidation or other transaction.

         2. 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 PM  Shares  for  shares  of APS  Common,
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.

                                       3
<PAGE>

         3.       SHARE CONVERSION.

                  (a)  Shareholder's  right to exchange its PM Shares  hereunder
shall  apply as to all,  but not less  than  all,  of the PM  Shares  which  are
eligible for exchange as described in this  paragraph (a) of Section 3. Assuming
Shareholder  has complied  with all of the  conditions  allowing for an exchange
pursuant  to this  Agreement,  30,000 of the PM  Shares  shall be  eligible  for
conversion as provided in this Agreement; and the remaining 40,000 PM Shares, or
a portion thereof,  will only be eligible for an exchange hereunder in the event
there is consummation of a transaction  between  Practice  Management 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  enters into
binding and  enforceable  agreements  with  Practice  Management of the type and
nature  ordinarily  relied  upon by Practice  Management  in its  dealings  with
physicians  on or before the  Determination  Date.  In the event that there is a
consummation of any such transaction on or before the  Determination  Date, then
the portion of the 40,000 PM 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  5,000 by the  number  of
physicians  in Bexar County,  Texas,  save and except for those  physicians  set
forth on Exhibit A attached  hereto and  incorporated  herein for all  purposes,
consummating such transactions.

                  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 

                                       4
<PAGE>

transaction  between Practice Management and any of
the  physicians  set forth on Exhibit A attached  hereto and (ii) any portion of
the  40,000 PM Shares  which  have not,  as of the  Determination  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  Expiration  Date. The
maximum number of PM Shares which Shareholder has the right to exchange pursuant
to  paragraph  (a)  of  this  Section  are   hereinafter   referred  to  as  the
"Exchangeable  PM Shares";  and the "Gross  Exchange Value" for purposes of this
Agreement is the gross dollar amount  determined by multiplying the Exchangeable
PM Shares by $5.00 per share (the "Exchange Value"). For purposes of determining
the number of shares of APS Common which may be received upon any  exchange,  no
consideration  will be given to stock  dividends,  stock  splits,  reverse stock
splits or  recapitalizations  to which Practice  Management or the PM Shares are
subject after the date this Agreement was originally entered into as first above
written. At the Closing, Shareholder shall be entitled to receive 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.

                                       5
<PAGE>

         (c) At the Closing,  Shareholder shall tender its share  certificate(s)
for all of the Exchangeable PM 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 PM Shares and that the Exchangeable PM
Shares  are  being  transferred  to APS free and clear of all  liens,  claims or
encumbrances of any kind  whatsoever.  The shares of APS Common that Shareholder
receives in the  exchange are  hereinafter  referred to as the "New APS Shares."
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  conversion  calculation  shall be rounded up or down, as the
case  may be,  to the  next  whole  number  of  shares.  APS  shall  be under no
obligation to pay any cash or other amounts with respect to any fractional share
amounts,  or to issue  any  fractional  share  amounts  to  Shareholder.  At the
Closing,  Shareholder  shall either receive a share  certificate for all its New
APS Shares or, if APS' transfer  agent is unable to produce such  certificate 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 in
the name of Shareholder directly to Shareholder or Shareholder's designee.

         4. NEW APS  SHARES  TRANSFERABILITY.  APS will have  registered  at its
expense the New APS Shares with the Securities and Exchange Commission, and made
such other filings and taken such other steps as necessary,  so that Shareholder
may  immediately  sell,  or  otherwise  convey,   the  New  APS  Shares  without
restriction  (except  as  otherwise  provided  below).  

                                       6
<PAGE>

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 the New APS
Shares for such period of time (not to exceed one hundred  eighty (180) days) as
may be requested by such lead underwriter.

         5.       MISCELLANEOUS.

                  (a) Fees and Expenses.  Except as otherwise  herein  provided,
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  

                                       7
<PAGE>

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  to the  relevant  party at its address as set forth

         3.       SHARE CONVERSION.

                  (a)  Shareholder's  right to exchange its PM Shares  hereunder
shall  apply as to all,  but not less  than  all,  of the PM  Shares  which  are
eligible for exchange as described in this  paragraph (a) of Section 3. Assuming
Shareholder  has complied  with all of the  conditions  allowing for an exchange
pursuant  to this  Agreement,  47,250 of the PM  Shares  shall be  eligible  for
conversion as provided in this Agreement; and the remaining 21,000 PM 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  the
Determination  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 Determination Date is hereinafter  referred to as the "Clinic
PAE." The parties  acknowledge  and agree that in the event  Clinic PAE does not
exceed  $315,000  during any twelve (12)  consecutive  calendar  monthly  period
ending on or prior to the  Determination  Date, then no portion of the 21,000 PM
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  Determination  Date,  the Clinic PAE  exceeds  $315,000,  then the
percentage of the 21,000 PM 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  21,000 by a fraction,  the
numerator of which is the amount by which Clinic PAE exceeds  $280,000  (but not
greater than $70,000 in any event), and the denominator of which is $70,000.

                                       4

         EXAMPLE:  The following is provided  purely by way of example only, and
illustrates  the  calculation  of the number of PM 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 $315,000 for the 12 months ended December
                  31,  1998,  which is the  largest  twelve  (12) month level of
                  Clinic PAE  achieved  in any  period  ended on or prior to the
                  Determination Date.

                  Total PM  Shares  eligible  for  exchange  hereunder  would be
                  57,750 determined as follows:

                  $315,000- $280,000      x      21,000          =      10,500
                  ------------------
                       $70,000
                                                                 +      47,250  
                                                                       -------
                                                                        57,750  
                                                                       =======

         (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 Expiration Date. The maximum number of
PM Shares which  Shareholder has the right to exchange pursuant to paragraph (a)
of this Section are hereinafter referred to as the "Exchangeable PM Shares"; and
the "Gross  Exchange  Value" for purposes of this  Agreement is the gross dollar
amount  determined by  multiplying  the  Exchangeable  PM Shares by the Exchange
Value.  For purposes of determining the number of shares of APS Common which may
be  received  upon  any  exchange,  no  consideration  will be  


                                       5
<PAGE>

given  to  stock
dividends,  stock  splits,  reverse stock splits or  recapitalizations  to which
Practice  Management or the PM Shares are subject after the date this  Agreement
was originally entered into as first above written. At the Closing,  Shareholder
shall be  entitled  to receive  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.

         (c) At the Closing,  Shareholder shall tender its share  certificate(s)
for all of the Exchangeable PM 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 PM Shares and that the Exchangeable PM
Shares  are  being  transferred  to APS free and clear of all  liens,  claims or
encumbrances of any kind  whatsoever.  The shares of APS Common that Shareholder
receives in the  exchange are  hereinafter  referred to as the "New APS Shares."
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  conversion  calculation  shall be rounded up or down, as the
case  may be,  to the  next  whole  number  of  shares.  APS  shall  be under no
obligation to pay any cash or other amounts with respect to any fractional share
amounts,  or to issue  any  fractional  share  amounts  to  Shareholder.  At the
Closing,  Shareholder  shall either receive a share  certificate for all its New
APS Shares or, if APS' transfer  agent is unable to 

                                       6
<PAGE>

produce such  certificate 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 in
the name of Shareholder directly to Shareholder or Shareholder's designee.

         4. NEW APS SHARES TRANSFERABILITY. APS will have registered the New APS
Shares with the Securities and Exchange Commission,  and made such other filings
and taken such other steps as necessary,  so that  Shareholder  may  immediately
sell, or otherwise  convey,  the New APS Shares 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 the
New APS Shares for such period of time (not to exceed one hundred  eighty  (180)
days) as may be requested by such lead underwriter.

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

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

                            SHARE EXCHANGE AGREEMENT


         This Share Exchange  Agreement  (this  "Agreement") is made and entered
into as of the  30th day of  June,  1998,  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")  entered into by Shareholder of even date herewith and
the other  contracts and  agreements to which  Shareholder  was, or was to be, 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 has acquired or will acquire 33,934 shares
(the "PM  Shares")  of the  $0.001 par value per share  common  stock of Syntera
HealthCare  Corporation,  a Texas corporation ("Syntera") for a consideration of
$5 per PM Share (in aggregate, the "Exchange Value"); and

         WHEREAS,  APS has agreed,  on the terms and  subject to the  conditions
hereof, to exchange certain shares of its $0.10 par value per share common stock
("APS Common") for the PM Shares.

         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:
<PAGE>


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

                  (a) There shall not have been,  on or before July 1, 2000 (the
"Determination  Date"),  any registered  public  offering of the common stock of
Syntera,  or any other  transaction or event pursuant to which shares of Syntera
of the same class as the PM Shares  shall have become  publicly  traded at a per
share price of greater than $5; 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"),  materially in breach of, or default under, this
Agreement,  any of the Acquisition  Documents or any other contract or agreement
to which  Shareholder and Syntera and/or APS are parties,  and Shareholder shall
not have threatened to materially breach or default under this Agreement, any of
the Acquisition Documents or any such other contract or agreement; 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 PM Shares, and the PM Shares are free of any
and all liens, claims or encumbrances of any kind whatsoever; and

                                       2
<PAGE>


                  (d) At 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

                                       3
<PAGE>


which  Syntera was not or would not be, the named  surviving  entity  after such
merger, consolidation or other transaction.

         2. 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  his  right  to  exchange  his PM  Shares  for  shares  of APS  Common,
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.

         3. SHARE  CONVERSION.  Shareholder's  right to  exchange  his PM Shares
hereunder shall apply as to all, but not less than all, of the PM Shares. 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 (i) the  Expiration  Date,  or (ii) in the
event a Lock-Up Period (as hereinafter defined) is imposed pursuant to Section 4
hereof,  the day on which such Lock-Up Period ends..  For purposes  hereof,  any
additional  shares of  Syntera  stock of any  class  which  Shareholder  obtains


                                       4
<PAGE>

pursuant  to  stock   dividends,   stock   splits,   reverse   stock  splits  or
recapitalizations  to which  Syntera or the PM Shares are subject after the date
this Agreement was

                                       5
<PAGE>


originally  entered into as first  written  above shall also be considered to be
included in the PM Shares;  however,  no adjustment or modification will be made
to the  Exchange  Value as a result  of any such  transaction.  At the  Closing,
Shareholder  shall be  entitled  to  receive  such  shares  of APS  Common as is
determined by dividing the 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.

         At the Closing,  Shareholder shall tender his share  certificate(s) for
all of the PM 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 PM Shares and that the PM Shares are being transferred to APS free
and clear of all liens, claims or encumbrances of any kind whatsoever.

         The shares of APS Common that Shareholder  receives in the exchange are
hereinafter  referred to as the "New APS  Shares." 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
conversion  calculation  shall be rounded up or down, as the case may be, to the
next whole number of shares. APS shall be under no obligation to pay any cash or
other  amounts with respect to any  fractional  share  amounts,  or to issue any
fractional  share  amounts to  Shareholder.  At the Closing,  Shareholder  shall
either  receive  a share  certificate  for all 

                                       6
<PAGE>

its New APS  Shares  or,  if APS'
transfer agent is unable to produce such  certificate 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  in the name of
Shareholder directly to Shareholder or Shareholder's designee.

         4. NEW APS SHARES TRANSFERABILITY. APS will have registered the New APS
Shares with the Securities and Exchange Commission,  and made such other filings
and taken such other steps as necessary,  so that  Shareholder  may  immediately
sell, or otherwise  convey,  the New APS Shares 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 the
New APS Shares 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").

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 Travis County, 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.

(the "Merger  Agreement")  entered into by Shareholder of even date herewith and

<PAGE>

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

of  Syntera,  or any other  transaction  or event  pursuant  to which  shares of
Syntera of the same class as the PM Shares  shall have become  publicly  traded;
provided  that Syntera shall not go public at a per share price of less than $5;
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 and/or APS are parties,  and Shareholder  shall not have
threatened to breach or default  under this  Agreement,  any of the  Acquisition
Documents or any such other contract or agreement; 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 

                                       2
<PAGE>

PM Shares, and the PM Shares are free of any
and all liens, claims or encumbrances of any kind whatsoever; and

                  (d) At 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.

         2. 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 PM  Shares  for  shares  of APS  Common,
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.

         3. SHARE  CONVERSION.  Shareholder's  right to  exchange  its PM Shares
hereunder shall apply as to all, but not less than all, of the PM Shares. In the
event  Shareholder  has  complied  with all of the  conditions  allowing  for an
exchange  pursuant  to this  Agreement,  the closing of 

                                       3
<PAGE>

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 (i) the  Expiration  Date,  or (ii) in the
event a Lock-Up Period (as hereinafter defined) is imposed pursuant to Section 4
hereof,  the day on which such Lock-Up  Period ends.  For purposes  hereof,  any
additional  shares of  Syntera  stock of any  class  which  Shareholder  obtains
pursuant  to  stock   dividends,   stock   splits,   reverse   stock  splits  or
recapitalizations  to which  Syntera or the PM Shares are subject after the date
this Agreement was originally  entered into as first written above shall also be
considered  to  be  included  in  the  PM  Shares;  however,  no  adjustment  or
modification will be made to the per share price hereunder of Syntera stock as a
result of any such transaction. At the Closing, Shareholder shall be entitled to
receive such shares of APS Common as is determined by multiplying  the number of
PM Shares referred to in the Recitals to this Agreement by $5, and dividing such
amount (the  "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.

         At the Closing,  Shareholder shall tender its share  certificate(s) for
all of the PM 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


                                       4
<PAGE>

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

         The shares of APS Common that Shareholder  receives in the exchange are
hereinafter  referred to as the "New APS  Shares." 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
conversion  calculation  shall be rounded up or down, as the case may be, to the
next whole number of shares. APS shall be under no obligation to pay any cash or
other  amounts with respect to any  fractional  share  amounts,  or to issue any
fractional  share  amounts to  Shareholder.  At the Closing,  Shareholder  shall
either  receive  a share  certificate  for all its New APS  Shares  or,  if APS'
transfer agent is unable to produce such  certificate 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  in the name of
Shareholder directly to Shareholder or Shareholder's designee.

         4. NEW APS SHARES  TRANSFERABILITY.  APS will have  registered,  at its
expense,  the New APS Shares with the  Securities and Exchange  Commission,  and
made such  other  filings  and taken  such  other  steps as  necessary,  so that
Shareholder  may  immediately  sell,  or  otherwise  convey,  the New APS Shares
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  

                                       5
<PAGE>

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 the New APS
Shares 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").

         5.       MISCELLANEOUS.

                  (a) FEES AND EXPENSES.  Except as otherwise  herein  provided,
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.

         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:

transaction.

         2. EXCHANGE  NOTICE.  In the event all of the  conditions  described in
Section 1 are satisfied as of the Determination  Date and Shareholder  elects to

thirty  (30) days  after the later 

                                       3
<PAGE>

of (i) the  Expiration  Date,  or (ii) in the
event a Lock-Up Period (as hereinafter defined) is imposed pursuant to Section 4

additional  shares of  Syntera  stock of any  class  which  Shareholder  obtains
pursuant  to  stock   dividends,   stock   splits,   reverse   stock  splits  or
recapitalizations  to which  Syntera or the PM Shares are subject after the date
this Agreement was originally  entered into as first written above shall also be
considered  to  be  included  in  the  PM  Shares;  however,  no  adjustment  or
modification  will  be  made to the  Exchange  Value  as a  result  of any  such
transaction.  At the  Closing,  Shareholder  shall be entitled  to receive  such
shares of APS Common as is  determined  by dividing  the  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.

         At the Closing,  Shareholder shall tender its share  certificate(s) for
all of the PM 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 PM Shares and that the PM Shares are being transferred to APS free
and clear of all liens, claims or encumbrances of any kind whatsoever.

         The shares of APS Common that Shareholder  receives in the exchange are
hereinafter  referred to as the "New APS  Shares." The parties  acknowledge  and
agree  that  Shareholder  shall  

                                       4
<PAGE>

receive a whole  number of shares of APS Common
only,  and  that any  fractional  share  amounts  resulting  from the  foregoing
conversion  calculation  shall be rounded up or down, as the case may be, to the
next whole number of shares. APS shall be under no obligation to pay any cash or
other  amounts with respect to any  fractional  share  amounts,  or to issue any
fractional  share  amounts to  Shareholder.  At the Closing,  Shareholder  shall
either  receive  a share  certificate  for all its New APS  Shares  or,  if APS'
transfer agent is unable to produce such  certificate 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  in the name of
Shareholder directly to Shareholder or Shareholder's designee.

         4. NEW APS SHARES TRANSFERABILITY. APS will have registered the New APS
Shares with the Securities and Exchange Commission,  and made such other filings
and taken such other steps as necessary,  so that  Shareholder  may  immediately
sell, or otherwise  convey,  the New APS Shares 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

                            SHARE EXCHANGE AGREEMENT


         This Share Exchange  Agreement  (this  "Agreement") is made and entered
into as of the 15th day of September,  1998, 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")  entered into by Shareholder of even date herewith and
the other  contracts and  agreements to which  Shareholder  was, or was to be, 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 has acquired or will acquire Seventy Four
Thousand  Four  Hundred  Forty Eight  (74,448)  shares (the "PM  Shares") of the
$0.001 par value per share common  stock of Syntera  HealthCare  Corporation,  a
Texas  corporation  ("Syntera")  for a  consideration  of $5  per PM  Share  (in
aggregate, the "Exchange Value"); and

         WHEREAS,  APS has agreed,  on the terms and  subject to the  conditions
hereof, to exchange certain shares of its $0.10 par value per share common stock
("APS Common") for the PM Shares.

<PAGE>


         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.  CONDITIONS  TO EXCHANGE  RIGHT.  In addition to the other terms and
conditions  contained in this Agreement,  Shareholder  shall only be entitled to
exchange  the PM  Shares  for  shares  of APS  Common  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 the common stock
of  Syntera,  or any other  transaction  or event  pursuant  to which  shares of
Syntera of the same class as the PM Shares shall have become publicly traded, at
a per share price of greater than $5; 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  and/or APS 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 PM Shares, and the PM Shares are free of any
and all liens, claims or encumbrances of any kind whatsoever; and

                                       2
<PAGE>

                  (d) At 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.

         2.  EXCHANGE  NOTICE.   In  the  event  the  conditions   described  in
subsections (a) and (d) of Section 1 are satisfied as of the Determination  Date
and  Shareholder  elects to  exercise  its right to  exchange  its PM Shares for
shares of APS Common,  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 subsections  (a) and (d) of
Section 1 above, fail to be satisfied on or prior to the Determination  Date, or
(ii) any of the conditions specified in subsections (b) or (c) of Section 1 fail
to be satisfied on 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.

         3. SHARE  CONVERSION.  Shareholder's  right to  exchange  its PM Shares
hereunder shall apply as to all, but not less than all, of the PM Shares. 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

                                       3
<PAGE>

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 (i) the  Expiration  Date,  or (ii) in the
event a Lock-Up Period (as hereinafter defined) is imposed pursuant to Section 4
hereof,  the day on which such Lock-Up  Period ends.  For purposes  hereof,  any
additional  shares of  Syntera  stock of any  class  which  Shareholder  obtains
pursuant  to  stock   dividends,   stock   splits,   reverse   stock  splits  or
recapitalizations  to which  Syntera or the PM Shares are subject after the date
this Agreement was originally  entered into as first written above shall also be
considered  to  be  included  in  the  PM  Shares;  however,  no  adjustment  or
modification  will  be  made to the  Exchange  Value  as a  result  of any  such
transaction.  At the  Closing,  Shareholder  shall be entitled  to receive  such
shares of APS Common as is  determined  by dividing  Three  Hundred  Seventy Two
Thousand Two Hundred  Forty  Dollars  ($372,240) 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.

         At the Closing,  Shareholder shall tender its share  certificate(s) for
all of the PM 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 PM Shares and that the PM Shares are being transferred to APS free
and clear of all liens, claims or encumbrances of any kind whatsoever.

                                       4
<PAGE>

         The shares of APS Common that Shareholder  receives in the exchange are
hereinafter  referred to as the "New APS  Shares." 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
conversion  calculation  shall be rounded up or down, as the case may be, to the
next whole number of shares. APS shall be under no obligation to pay any cash or
other  amounts with respect to any  fractional  share  amounts,  or to issue any
fractional  share  amounts to  Shareholder.  At the Closing,  Shareholder  shall
either  receive  a share  certificate  for all its New APS  Shares  or,  if APS'
transfer agent is unable to produce such  certificate 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  in the name of
Shareholder directly to Shareholder or Shareholder's designee.

         4. NEW APS SHARES TRANSFERABILITY. APS will have registered the New APS
Shares with the Securities and Exchange Commission,  and made such other filings
and taken such other steps as necessary,  so that  Shareholder  may  immediately
sell, or otherwise  convey,  the New APS Shares 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

                                       5
<PAGE>

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 the
New APS Shares 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").

         5.       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.

rights or obligations  hereunder,  without the express prior written  consent of

                            SHARE EXCHANGE AGREEMENT

         This Share Exchange  Agreement  (this  "Agreement") is made and entered
into as of the 31st day of December,  1998, by and between  American  Physicians

                                R E C I T A L S:

         WHEREAS,  pursuant to that certain Agreement and Plan of Reorganization
(the "Merger  Agreement")  entered into by Shareholder of even date herewith and
the other  contracts and  agreements to which  Shareholder  was, or was to be, 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 has acquired or will acquire 64,642 shares

         WHEREAS,  APS has agreed,  on the terms and  subject to the  conditions
hereof, to exchange certain shares of its $0.10 par value per share common stock
("APS Common") for the PM Shares.

         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.  CONDITIONS  TO EXCHANGE  RIGHT.  In addition to the other terms and
conditions  contained in this Agreement,  Shareholder  shall only be entitled to
exchange  the PM  Shares  for  shares  of APS  Common  if each of the  following

(the  "Determination  Date"), any registered public offering of the common stock
of  Syntera,  or any other  transaction  or event  pursuant  to which  shares of
Syntera of the same class as the PM Shares shall have become  publicly traded at
a per share price of greater  than $7.70 (as adjusted  for stock  splits,  stock
dividends, combinations and other recapitalizations); 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 and/or APS are parties,  and Shareholder  shall not have
threatened to breach or default  under this  Agreement,  any of the  Acquisition
Documents or any such other contract or agreement; and

                  (c) At the Closing Date,  Shareholder  has all requisite legal

                  (d) At 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.

         2. 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 PM  Shares  for  shares  of APS  Common,
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

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

Shareholder  has complied  with all of the  conditions  allowing for an exchange
pursuant  to this  Agreement,  35,422 of the PM  Shares  shall be  eligible  for
conversion as provided in this Agreement; and the remaining 29,220 PM 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  the
Determination  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 Determination 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  Determination  Date, then no portion of the 29,220 PM
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  Determination  Date,  the Clinic PAE  exceeds  $450,000,  then the
percentage of the 29,220 PM 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  29,220 by a fraction,  the
numerator of which is the amount by which 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 PM 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
                  Determination Date.

                  Total PM  Shares  eligible  for  exchange  hereunder  would be
                  determined as follows:

                  $475,000 - $400,000       x     29,220       =      21,915
                  -------------------
                            $100,000
                                                               +      35,422
                                                                      ------
                                                                      57,337
                                                                      ======

         (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 (i) the  Expiration  Date, or
(ii) if a Lock-Up Period (as hereinafter defined) is imposed pursuant to Section
4 hereof,  the day on which such Lock-Up  Period ends.  The maximum number of PM
Shares which  Shareholder has the right to exchange pursuant to paragraph (a) of
this Section are hereinafter  referred to as the  "Exchangeable PM Shares";  and
the "Gross  Exchange  Value" for purposes of this  Agreement is the gross dollar
amount  determined by  multiplying  the  Exchangeable  PM Shares by the Exchange
Value.  For purposes of determining the number of shares of APS Common which may
be  received  upon  any  exchange,  no  consideration  will be  given  to  stock
dividends,  stock  splits,  reverse stock splits or  recapitalizations  to which
Syntera  or the PM  Shares  are  subject  after  the  date  this  Agreement  was
originally  entered into as first above  written.  At the  Closing,  Shareholder
shall be  entitled  to receive  such  shares of APS Common as is  determined  by


                                       4
<PAGE>

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.

         (c) At the Closing,  Shareholder shall tender its share  certificate(s)
for all of the Exchangeable PM 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 PM Shares and that the Exchangeable PM
Shares  are  being  transferred  to APS free and clear of all  liens,  claims or
encumbrances of any kind  whatsoever.  The shares of APS Common that Shareholder
receives in the  exchange are  hereinafter  referred to as the "New APS Shares."
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  conversion  calculation  shall be rounded up or down, as the
case  may be,  to the  next  whole  number  of  shares.  APS  shall  be under no
obligation to pay any cash or other amounts with respect to any fractional share
amounts,  or to issue  any  fractional  share  amounts  to  Shareholder.  At the
Closing,  Shareholder  shall either receive a share  certificate for all its New
APS Shares or, if APS' transfer  agent is unable to produce such  certificate 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 in
the name of Shareholder directly to Shareholder or Shareholder's designee.

         4. NEW APS SHARES TRANSFERABILITY. APS will have registered the New APS
Shares with the Securities and Exchange Commission,  and made such other filings
and taken such other steps as necessary,  so that  Shareholder  may  immediately
sell, or otherwise  convey,  the New APS Shares 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


                                       5
<PAGE>

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 the
New APS Shares 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").

         5.       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 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.

this  Agreement,  the Previous Owner shall execute,  acknowledge  and deliver or
cause to be delivered to Newco such documents of title and  conveyance  relating
to the Real  Property as APS may request;  provided that those liens on the Real

         The combined  indemnity  obligation of Trevey or Bouchard  arising from
the  provisions of this Section for any one or more claimed  losses or events of
damage,  whether  directly  or by reason of their  ownership  of or  receipt  of
distributions from the General Partner or either  Partnership,  shall not exceed
an  amount  equal to the  value,  as of the time for  payment  of the  indemnity
obligation  in question and before  taking into  account the effect,  if any, on
such value of the loss, claim or damage giving rise to the indemnity  obligation
in  question  and any other  alleged  or  asserted  indemnity  obligations  then
outstanding,  of an interest in Newco  corresponding  to an aggregate  ownership
interest in Newco of 1,100,000 shares of Common Stock,  reduced by the number of
shares of Common Stock previously transferred by Bouchard or Trevey to any party
hereto pursuant to the indemnity  provisions hereof (as the same may be adjusted
for stock  splits and stock  dividends  occurring  after the date  hereof).  The
indemnity  obligation of each of Trevey and Bouchard  taken  separately  arising
from the provisions of this Section for any one or more claimed losses or events
of  damage,  whether  directly  or by reason of his  ownership  of or receipt of
distributions from the General Partner or either  Partnership,  shall not exceed
an amount  equal to one-half  the amount  calculated  pursuant to the  preceding
sentence.  Neither  Trevey nor  Bouchard  shall be  obligated to pay any cash or
property  other than Newco Common Stock on account of any  indemnity  obligation
accruing  hereunder  unless,  in  violation  of any  term  or  provision  of the
Shareholders  Agreement, he has previously transferred (other than in connection
with the payment of an indemnity  obligation)  any of the shares of Common Stock
issued to him at the Closing  (including  shares of Common Stock  transferred to
him by the  General  Partner  or the  Partnerships  from  the  shares  initially
received  by the  General  

                                       37
<PAGE>

Partner or the  Partnerships  at the  Closing) or any
shares of Common  Stock  issued  without  consideration  in  respect of any such
shares;  if either  Trevey or  Bouchard  has made such a  transfer,  he shall be
liable to pay cash in respect of any indemnity obligation arising hereunder only
to the  amount  of the  value of such  shares  of  Common  Stock so  transferred
(calculated in accordance with the first sentence of this paragraph), subject to
the limits on aggregate  liability  set forth in this  paragraph.  Any indemnity
obligation  owed by either Trevey or Bouchard  hereunder shall be payable first,
and to the  extent  possible,  by  transfer  by Trevey  and/or  Bouchard  to the
appropriate APS Indemnified  Parties of that number of shares of Common Stock of
Newco equal in value  (with  value  determined  before  taking into  account the
effect,  if any, on such value of the loss,  claim or damage  giving rise to the
indemnity  obligation  in question and any other  alleged or asserted  indemnity
obligations  then  outstanding) to the indemnified  loss. Any actual recovery by
the APS Indemnified Parties from any other Control Party shall first be deducted
in arriving  at the  remaining  aggregate  indemnity  obligations  of Trevey and
Bouchard.  Any shares of Newco  Common Stock  transferred  by Trevey or Bouchard
under the  provisions of this Section shall be  distributed  pro rata to each of
the APS Indemnified  Parties based upon the  proportionate  share of Indemnified
Costs incurred by each such party. In the event that Newco shall receive,  as an
APS  Indemnified  Party,  shares  of  stock  forfeited  by  Trevey  or  Bouchard
hereunder,  such stock shall be  recorded on Newco's  books and held by Newco as
treasury  stock.  In determining  the value of Common Stock for purposes of this
Section, the methodology  specified for determining  "Appraised Value" under the
provisions of Section 5.2 of the Shareholders Agreement shall be utilized.

         The APS  Indemnified  Parties  and all parties  claiming  under the APS
Indemnified  Parties waive any right of  subrogation  with respect to any matter
indemnified  hereunder  to the  extent  of  insurance  actually  in force  which
provides coverage with respect to such indemnified event.  Furthermore,  the APS


                                       38
<PAGE>

Indemnified  Parties and all parties claiming under the APS Indemnified  Parties
agree not to assign or transfer (by  subrogation  or otherwise) to any insurance
carrier or any third-party  claiming under any insurance  carrier,  any right of
recovery under this Agreement.

         Notwithstanding the foregoing or any other provision of this Agreement,
any obligations  arising in connection with a breach,  or threatened  breach, by
Trevey and/or Bouchard, as the case may be, of the provisions of Section 10.3 or
Article 9 hereof shall not be subject to the foregoing  limitations or manner of
payment provisions, or any other limitations or qualifications, and in the event
of any such breach, or threatened  breach,  of any such provisions,  the parties
seeking relief related thereto shall have all remedies available to them at law,
in equity, or otherwise.

         Section 7.2 DEFENSE OF THIRD-PARTY  CLAIMS.  An APS  Indemnified  Party
shall  give  prompt  written  notice  to  each  of the  Control  Parties  of the
commencement or assertion of any third party action in respect of which such APS
Indemnified Party shall seek indemnification hereunder. Any failure so to notify
the Control  Parties  shall not relieve the Control  Parties from any  liability
that they may have to such APS  Indemnified  Party under this Article unless the
failure to give such notice  materially  and  adversely  prejudices  the Control
Parties.  The  Control  Parties  shall  have the right to assume  control of the
defense of, settle or otherwise dispose of such third-party action on such terms
as it deems appropriate; provided, however, that:

         (a) The APS  Indemnified  Party shall be entitled,  at his, her, or its
own expense, to participate in the defense of such third-party action;

         (b) The Control Parties shall obtain the prior written  approval of the
APS Indemnified Party, which approval shall not be unreasonably withheld, before
entering into or making any settlement,  

                                       39
<PAGE>

compromise, admission or acknowledgment
of the validity of such  third-party  action or any liability in respect thereof
if,  pursuant to or as a result of such  settlement,  compromise,  admission  or
acknowledgment,  injunctive or other  equitable  relief would be imposed against
the APS Indemnified Party;

         (c) None of the  Control  Parties  shall  consent  to the  entry of any
judgment or enter into any settlement that does not include as an  unconditional
term  thereof the  execution  and  delivery of a release  from all  liability in
respect of such  third-party  action by each  claimant or  plaintiff  to, and in
favor of, each APS Indemnified Party; and

         (d) None of the Control Parties shall be entitled to control (but shall
be entitled to  participate at their own expense in the defense of), and the APS
Indemnified  Party shall be entitled to have sole control  over,  the defense or
settlement, compromise, admission or acknowledgment of any third-party action as
to which the Control Parties fail to assume the defense within thirty (30) days;
provided,  however,  that the APS  Indemnified  Party shall make no  settlement,
compromise,  admission or  acknowledgment  which would give rise to liability on
the part of the  Control  Parties,  without  the prior  written  consent  of the
Control Parties.

         (e) The Control Parties shall make payments of all amounts  required to
be made  pursuant  to the  foregoing  provisions  of this  Article to or for the
account of the APS Indemnified  Party from time to time promptly upon receipt of
bills or invoices  relating thereto or when otherwise due and payable,  provided
that the APS  Indemnified  Party has agreed in writing to reimburse  the Control
Parties for the full amount of such  payments  if the APS  Indemnified  Party is
ultimately determined not to be entitled to such indemnification. If the Control
Parties fail to timely remit  payments of amounts owed  hereunder,  such amounts


                                       40
<PAGE>

shall  accrue  interest  at the  maximum  rate  of  interest  permissible  under
applicable state or federal law.

         (f)  The  parties  hereto  shall  extend   reasonable   cooperation  in
connection with the defense of any  third-party  action pursuant to this Article
and, in  connection  therewith,  shall  furnish such  records,  information  and
testimony and attend such conferences,  discovery proceedings,  hearings, trials
and appeals as may be reasonably requested.

                                  ARTICLE VIII
                     INDEMNIFICATION OF THE CONTROL PARTIES

         Section 8.1  Indemnification  by APS. APS agrees to indemnify  and hold
harmless  the  Control  Parties  and  the  Limited  Partner  (collectively,  the
"Indemnified Control Parties") from and against any and all Indemnified Costs in
connection  with the  commencement  or assertion of any third party action which
any of the Indemnified Control Parties may sustain, arising out of any breach or
default  by  APS  of  any  of  its  representations,  warranties,  covenants  or
agreements  contained in this Agreement or any agreement or document executed in
connection  herewith   (including,   without   limitation,   the  Organizational
Documents).  Notwithstanding  the  foregoing  or any  other  provision  of  this
Agreement,  an  obligation  of APS shall arise under this Section only if and to
the extent  that  Indemnified  Costs  owed to all  Indemnified  Control  Parties
hereunder, in the aggregate, exceed $100,000.

         The  Indemnified  Control  Parties and all parties  claiming  under the
Indemnified  Control Parties waive any right of subrogation  with respect to any
matter indemnified  hereunder to the extent of insurance actually in force which
provides  coverage  with respect to such  indemnified  event.  Furthermore,  the
Indemnified  Control  

                                       41
<PAGE>

Parties and all  parties  claiming  under the  Indemnified
Control Parties agree not to assign or transfer (by subrogation or otherwise) to
any insurance carrier or any third-party  claiming under any insurance  carrier,
any right of recovery under this Agreement.

         Section 8.2 INDEMNIFICATION BY THE LIMITED PARTNER. The Limited Partner
agrees to  indemnify  and hold  harmless  the  Control  Parties and APS from and
against any and all  Indemnified  Costs in connection  with the  commencement or
assertion of any third party action which any Control  Party or APS may sustain,
arising  out of any  breach or  default  by the  Limited  Partner  of any of its
representations, warranties, covenants or agreements contained in this Agreement
or any agreement or document  executed in connection  herewith.  Notwithstanding
the  foregoing or any other  provision of this  Agreement,  an obligation of the
Limited  Partner  shall arise under this  Section only if and to the extent that
Indemnified  Costs owed to all the  Control  Parties and APS  hereunder,  in the
aggregate, exceed $100,000.

         Section 8.3  INDEMNIFICATION  BY NEWCO.  Newco agrees to indemnify  and
hold harmless APS, the Control  Parties and the Limited Partner from and against
any and all  Indemnified  Costs arising from, or in connection  with, (a) any of
the liabilities specifically assumed by Newco at Closing pursuant to Section 1.6
hereof,  (b) any demands made against Trevey and Bouchard under the terms of the
personal  guaranty  and/or  maker  obligations  described in Section 1.8 hereof,
and/or (c) any  obligations or liabilities  with respect to any claims  asserted
based on the business of Newco conducted after the Closing.  Notwithstanding the
foregoing or any other provision of this Agreement, an obligation of Newco shall
arise under this Section only if and to the extent that  Indemnified  Costs owed
to all the  Control  Parties  and the  Limited  Partner  hereunder  (other  than
obligations arising pursuant to subsection (b) above), in the aggregate,  exceed
$100,000.

         Section 8.4 DEFENSE OF THIRD-PARTY  CLAIMS.  The  indemnified  party or
parties (both individually and collectively,  the "indemnified party") under the
foregoing  provisions  of this Article shall give prompt  written  notice to the
indemnifying  party  or  parties  (both   individually  and  collectively,   the
"indemnified  party")  under the  foregoing  provisions  of this  Article of the
commencement  or  assertion  of any third party  action in respect of which such
indemnified party shall seek indemnification hereunder. Any failure to so notify
the  indemnifying  party  shall not  relieve  such  indemnifying  party from any
liability that it may have to such  indemnified  party under this Article unless
the  failure  to give  such  notice  materially  and  adversely  prejudices  the
indemnifying  party.  The  indemnifying  party  shall  have the  right to assume
control of the  defense  of,  settle or  otherwise  dispose of such  third-party
action on such terms as it deems appropriate; provided, however, that:

         (a)      The indemnified  party shall be entitled,  at his, her or its 
own expense,  to participate in the defense of such third-party action;

         (b) The  indemnifying  party shall obtain the prior written approval of
the indemnified party, which approval shall not be unreasonably withheld, before
entering into or making any settlement,  compromise, admission or acknowledgment
of the validity of such  third-party  action or any liability in respect thereof
if,  pursuant to or as a result of such  settlement,  compromise,  admission  or
acknowledgment,  injunctive or other  equitable  relief would be imposed against
the indemnified party;

         (c) The  indemnifying  party  shall  not  consent  to the  entry of any
judgment or enter into any settlement that does not include as an  unconditional
term  thereof the  execution  and  delivery of a release  from all  liability in
respect of such  third-party  action by each  claimant or  plaintiff  to, and in
favor of, each indemnified party; and

                                       43
<PAGE>

         (d) The indemnifying  party shall not be entitled to control (but shall
be  entitled to  participate  at its own  expense in the  defense  of),  and the
indemnified  party shall be entitled to have sole control  over,  the defense or
settlement, compromise, admission or acknowledgment of any third-party action as
to which the  indemnifying  party fails to assume the defense within thirty (30)
days;  provided,  however,  that the indemnified party shall make no settlement,
compromise,  admission  or  acknowledgment  which  would give rise to  liability
(other than liability to the indemnified party under this Agreement) on the part
of the indemnifying party without the prior written consent of such indemnifying
party.

         (e) The indemnifying  party shall make payments of all amounts required
to be made  pursuant to the  foregoing  provisions of this Article to or for the
account of the  indemnified  party from time to time  promptly  upon  receipt of
bills or invoices  relating thereto or when otherwise due and payable,  provided
that the indemnified  party has agreed in writing to reimburse the  indemnifying
party  for the  full  amount  of  such  payments  if the  indemnified  party  is
ultimately  determined  not  to be  entitled  to  such  indemnification.  If the
indemnifying  party fails to timely remit  payments of amounts  owed  hereunder,
such amounts shall accrue  interest at the maximum rate of interest  permissible
under applicable state or federal law.



         (f)  The  parties  hereto  shall  extend   reasonable   cooperation  in
connection with the defense of any  third-party  action pursuant to this Article
and, in  connection  therewith,  shall  furnish such  records,  information  and
testimony and attend such conferences,  discovery proceedings,  hearings, trials
and appeals as may be reasonably requested.

                                   ARTICLE IX
                              RESTRICTIVE COVENANTS

         Section   9.1   RELEASE  OF   PARTNERSHIP   PROVISIONS.   Each  of  the
Partnerships,  the General  Partner,  the Limited  Partner,  Trevey and Bouchard
hereby  covenant  and agree that the General  Partner,  Trevey and  Bouchard are
hereby  released  from any  restrictive  agreements,  covenants,  provisions  or
conditions  contained in the  Articles of Limited  Partnership,  Certificate  of
Limited Partnership or other organizational  documents entered into with respect
to  the  Partnerships.  Without  limiting  the  foregoing,  it  is  specifically
acknowledged  and agreed  that the  provisions  of ARTICLE  XIII (Right of First
Refusal) of the Amended and Restated  Articles of Limited  Partnership of Barton
House,  and the  provisions  of ARTICLE  XIII  (Right of First  Refusal)  of the
Articles of Limited  Partnership  of Oakwell,  are hereby waived and released in
all respects and shall  hereafter be null and void.  It is expressly  agreed and
understood  that the  provisions  of this  Section  in no way  modify,  limit or
otherwise affect any obligations of the parties contained in

this  Article,  or  elsewhere  in this  Agreement,  or in any other  contract or
agreement  entered  into  pursuant  to the  transactions  contemplated  by  this
Agreement.

         Section  9.2  NON-DISCLOSURE  OF  PROPRIETARY  INFORMATION.  Each party
hereto agrees that through its  relationship and dealings with Newco, it will be
exposed   to   confidential   information   and  trade   secrets   ("Proprietary
Information")  pertaining  to, or arising from, the business of Newco or Newco's
affiliates,  that such  Proprietary  Information is unique and valuable and that
Newco or Newco's  affiliates would suffer irreparable injury if this information
were  divulged  to those  in 

                                       45
<PAGE>

competition  with  Newco  or  Newco's  affiliates.
Therefore,  each party  agrees to keep in strict  secrecy and  confidence,  both
during and after the period of its relationship or business dealings with Newco,
any and all information which it acquires, or to which it has access during such
relationship or through such dealings,  that has not been publicly  disclosed by
Newco or Newco's affiliates or that is not a matter of common knowledge by their
respective  competitors.  The Proprietary  Information covered by this Agreement
shall  include,  but  shall  not be  limited  to,  information  relating  to any
inventions,  processes,  software,  formulae,  plans,  devices,  compilations of
information,  technical data,  mailing lists,  management  strategies,  business
distribution  methods,  names of  suppliers  (of both  goods and  services)  and
customers, names of employees and terms of employment, arrangements entered into
with suppliers and customers,  including, but not limited to, proposed expansion
plans of Newco,  marketing and other  business and pricing  strategies and trade
secrets of Newco and Newco's  affiliates;  provided,  however,  that Proprietary
Information  shall not include any such  information  which has become generally
known to the public or in the relevant  trade or industry by means other than as
a result of unauthorized  disclosure by or at the direction of the party relying
on this exception.

         At all times after the Closing,  except with prior written  approval by
the Board of Directors of Newco (pursuant to Article VIII, subsection (t) of the
Shareholders  Agreement and Article 3, Section 8(t) of Newco's Bylaws),  in each
instance,  no party shall: (a) directly or indirectly,  disclose any Proprietary
Information  to any person  except  authorized  personnel  of Newco,  or (b) use
Proprietary  Information in any way not related solely to the business of Newco.
If such party is an employee of Newco or Newco's affiliates, upon termination of
employment,  whether voluntary or involuntary,  within forty-eight (48) hours of
termination,  such  employee  will deliver to Newco  

                                       46
<PAGE>

(without  retaining  copies
thereof) all documents,  records or other  memorializations  including copies of
documents  and  any  notes  which  such  employee  has  prepared,  that  contain
Proprietary  Information or relate to Newco's or Newco's  affiliates'  business,
all other tangible Proprietary Information in such party's possession or control
and all of Newco's  and  Newco's  affiliate's  credit  cards,  keys,  equipment,
vehicles,  supplies and other  materials  that are in  possession  or under such
employee's control.

         Notwithstanding the foregoing or any other provision of this Agreement,
any party shall be entitled to divulge or disclose  Proprietary  Information (x)
to  its   accountants,   attorneys,   bankers   or   financial   advisors   (its
"Representatives")  for the sole purpose of  representing  it in connection with
the  business  of Newco,  (y) in the event  that it or its  Representatives  are
requested or required  during or through legal  proceedings  by oral  questions,
interrogatories,  requests for  information  or documents,  subpoenas,  or other
similar legal process to disclose any of the Proprietary  Information,  but only
after such party  provides  the other  parties  hereto ten (10) days,  following
written notice of any such request or requirement, to seek a protective order or
other  appropriate  remedy,  or waive  compliance  with the  provisions  of this
subsection,  (z) it or  its  Representatives  are,  in the  written  opinion  of
qualified legal counsel  addressed and delivered to the other parties hereto not
less than ten (10) days prior to any disclosure,  legally  compelled to disclose
Proprietary Information to any tribunal,  agency or governmental regulatory body
or else stand liable for contempt or suffer other  censure or penalty,  but only
to the extent required under the circumstances.

         Section 9.3  NON-COMPETITION.  Each party to this Agreement (other than
Newco) hereby agrees that,  such party will not directly or  indirectly,  either
through any kind of ownership  

                                       47
<PAGE>

(other than ownership of securities of a publicly
held corporation,  or other entity, of which it owns less than five percent (5%)
of any class of outstanding securities), or as a principal,  shareholder, agent,
employer, advisor, consultant, co-partner or in any individual or representative
capacity  whatever,  either for its own  benefit or for the benefit of any other
person,  corporation or other entity,  without the prior written  consent of all
other  parties  hereto,  commit any of the following  acts,  which acts shall be
considered violations of this covenant not to compete:

          (a) Directly or indirectly (other than through Newco), anywhere within
any state of the United  States in which,  at the time such  party's  employment
relationship with Newco, if applicable, terminates, Newco owns, operates, or has
specific plans to acquire, develop or operate, a business location providing, or
to provide, any Covered Services (as herein defined),  engage in, or provide any
services related to the provision of assisted living services to senior citizens
with dementia, or any related services. For purposes of this Agreement, "Covered
Services"  means any  services  related  to the  provision  of  assisted  living
services to senior citizens with dementia or any related services.

         Notwithstanding the foregoing or any other provision of this Agreement,
(A) the  restrictions  contained in this subsection (a) shall lapse with respect
to Trevey on the later of (x) the fifth  anniversary of the Closing Date and (y)
the  second  anniversary  of the date that  Trevey  voluntarily  terminates  his
employment  with Newco,  (B) the  restrictions  contained in this subsection (a)
shall lapse with  respect to Bouchard on the later of (x) the fifth  anniversary
of the Closing  Date and (y) the second  anniversary  of the date that  Bouchard
voluntarily  terminates his employment with Newco,  and (C) if Newco  terminates
the employment of either Bouchard or

<PAGE>

Trevey, the restrictions  contained in this
subsection  (a) shall lapse with  respect to the  terminated  party on the first
anniversary of such termination.  The restrictions  contained in this subsection
(a) shall cease to be effective  with respect to all parties  hereto at any time
that  both  Bouchard  and  Trevey  are not  longer  bound by such  restrictions.
Furthermore,  in no event  shall  any party be bound by the  provisions  of this
subsection  (a) after the earlier to occur of (i) the  expiration  of five years
from the date the common stock of Newco becomes  publicly  traded pursuant to an
underwritten  registered  public  offering,  or (ii) the expiration of ten years
after the Closing Date.

         (b) Directly or indirectly,  for such party's own account or otherwise,
solicit  business  from,  divert  business  from or  attempt to convert to other
methods of using the same or similar  products  or services as provided by Newco
or Newco's  affiliates,  any  client,  account or  location  of Newco or Newco's
affiliates  with  which  such  party  has had any  contact  as a  result  of its
relationship and business dealings with Newco hereunder.

         (c)  Directly  or  indirectly  request  or  advise  any  person,  firm,
physician, corporation or other entity having a business relationship with Newco
or any  affiliate  of Newco,  to withdraw,  curtail or cancel its business  with
Newco or such affiliate.

         (d) Directly or indirectly  hire any employee of Newco or any affiliate
of Newco,  or  induce or  attempt  to  influence  any  employee  or  independent
contractor  of Newco or any such  affiliate  to  terminate  or modify his or her
employment or contractual arrangement with Newco or any such affiliate.

         Section 9.4  AGREEMENT OF THE  PARTIES.  Each party hereto has reviewed
and carefully  considered  the  provisions of this Article and,  having done so,
agrees that the restrictions applicable to them as set forth herein (a) are fair
and  reasonable  with respect to time,  geographic  area and scope,  (b) are not
unduly burdensome to them and (c) are reasonably  required for the protection of
the  interests of the other parties  hereto for whose benefit such  restrictions
were agreed upon.

         Section 9.5 REMEDIES.  Each party hereto understands,  acknowledges and
agrees that a violation on its part of any applicable covenant contained in this
Article will cause the other parties hereto for whose benefit such  restrictions
were  agreed  upon  irreparable  damage for which  remedies at law alone will be
insufficient,  and for that  reason,  each party  hereto  agrees  that the other
parties shall be entitled as a matter of right,  upon  application to a court of
competent  jurisdiction,  to  equitable  remedies  in  the  event  of  any  such
violation,  including specific performance and injunctive relief,  therefor. The
right to specific  performance and injunctive  relief shall be cumulative and in
addition to whatever other remedies, at law or in equity, that the other parties
may have, including, specifically, recovery of additional damages.

to  cooperate  fully with Newco in  transitioning  the business  conducted,  and
business  relationships  maintained  

                                       50

by  each  of the  Partnerships  (and by the
General  Partner as to the Assets  contributed to Newco by the General  Partner)
prior to the Closing, to Newco after the Closing (including, without limitation,
the re-registration in all applicable jurisdictions, under the name of Newco, of
all registered  trademarks or servicemarks included in the Assets); APS and each
Control  Party  agree not to take any action or make any  disclosure,  including
disclosures  related to the transactions  contemplated by this Agreement,  which
might  alter or impair any  relationship  with any  customer,  or other  service
recipient,  person or entity which did business with either of the  Partnerships
prior to the Closing.  Each Control Party agrees to promptly  remit to Newco any
payments  received by any Control  Party for services  provided by either of the
Partnerships after the Effective Time and before the Closing,  or by Newco after
the Closing. Furthermore, each of the Control Parties agrees to deposit any such
payments  received  directly to a deposit  account  designated and controlled by
Newco or to take such other action as may be  requested by APS to implement  and
maintain  a  system  for  remitting  payments  due  Newco  which  come  into the
possession or control of any Control Party. The provisions of this Section shall
not require any party hereto to incur out-of-pocket costs unless Newco pays for,
or agrees to reimburse, such costs.

         Section  10.2  RATIFICATION  BY  NEWCO.  Each and  every  party to this
Agreement  hereby  expressly  agrees that it will not  challenge or contest,  on
legal  grounds or  otherwise,  Newco's  execution of, and power and authority to
perform its obligations under, this Agreement, notwithstanding the official date
of Newco's creation.

         Section 10.3 EMPLOYMENT  WITH NEWCO.  Trevey and Bouchard each agree to
enter into an  Employment  Agreement  in the form  attached  hereto as Exhibit E
(collectively,  the "Employment Agreements") at the Closing. Trevey and Bouchard
each agree (a) to comply with the terms of his respective  Employment  Agreement
and (b) not to terminate his employment with Newco for so long as Newco complies
with the terms of the Employment Agreement.

         Section 10.4  DISPOSITION OF SUGARLAND  PROPERTY.  After Closing,  upon
maturity of that certain  promissory note dated December 2, 1997 in the original
principal  amount  of  $300,000,  arising  out of a loan  by APS to the  General
Partner,  (the  "Sugarland  Note"),  and secured by that certain  real  property
located  at 3050 and 3060  Edgewater  Boulevard,  Sugarland,  Texas  77479  (the
"Sugarland Property"),  Newco agrees to purchase, and the General Partner agrees
to sell,  the  Sugarland  Property  to  Newco  (free of all  liens,  claims  and
encumbrances)  in  exchange  for  Newco's  paying  to the  General  Partner,  in
immediately  available  funds, an amount of money equal to all amounts due under
the Sugarland Note. The General  Partner shall execute,  acknowledge and deliver
or cause to be delivered to Newco and APS such documents of title and conveyance
relating to the Sugarland  Property as Newco,  APS or their counsel may request.
All such documents  must be reasonably  acceptable in both form and substance to
Newco and APS and their  counsel,  and Newco  agrees to  reimburse  the  General
Partner for reasonable and necessary  out-of-pocket  costs incurred in obtaining
or providing such documents.

         Section 10.5 FORM D FILING. Following the Closing, Newco shall properly
and timely file with the  Securities  and Exchange  Commission a Form D, and all
parties agree to cooperate, as necessary, to facilitate such filing.

                                  MISCELLANEOUS

         Section  11.1  COLLATERAL  AGREEMENTS,  AMENDMENTS  AND  WAIVERS.  This
Agreement  (together with all documents  delivered pursuant hereto,  executed in
connection  herewith,  or contemplated  herein)  supersedes all other documents,
understandings  and  agreements,  oral or  written  and  constitutes  the entire
understanding  among the parties with respect to the subject matter hereof.  Any
modification  or amendment to, or waiver of, any provision of this Agreement (or
any document delivered pursuant to this Agreement or contemplated herein, unless
otherwise  expressly  provided  therein)  may be made only by an  instrument  in
writing executed by each party thereto.

         Section 11.2  SUCCESSORS AND ASSIGNS.  No party's rights or obligations
under  this  Agreement  may be  assigned,  transferred,  conveyed  or  otherwise
disposed of except pursuant to that certain  Shareholders  Agreement executed in
connection with this Agreement. Upon any such permitted assignment, the assignee
shall execute the  Shareholders  Agreement,  or a counterpart  thereof,  and the
assignor and the assignee shall thereafter be jointly and severally  responsible
for the obligations of assignor hereunder.  Furthermore,  no assignment,  of any
type,  of rights or  obligations  under this  Agreement  shall in any way limit,
modify or otherwise  affect the  obligations  of the  remaining  parties to this
Agreement.  Any assignment in violation of the foregoing shall be null and void.
Subject to the  preceding  sentences of this  Section,  the  provisions  of this
Agreement (and, unless otherwise  expressly  provided  therein,  of any document

                                       53
<PAGE>

delivered  pursuant to this Agreement or  contemplated  herein) shall be binding
upon and inure to the benefit of the parties hereto and their respective  heirs,
legal representatives, successors and assigns.

         Notwithstanding the foregoing or any other provision of this Agreement,
the  parties  hereto  acknowledge  and agree  that APS shall  have  unrestricted
rights,  upon written notice to the other parties  hereto,  to freely assign its
rights under this Agreement and the other  contracts or agreements  entered into
by APS pursuant  hereto,  to any entity,  the  majority of whose  voting  equity
securities is then owned directly or indirectly by APS; provided,  however, that
APS shall remain fully  liable for all its  obligations  hereunder or under such
other contracts or agreements after any such assignment.

         Section 11.3 EXPENSES.  Except as set forth in the following  sentence,
regardless of whether the transactions contemplated hereby are consummated, each
party  hereto  shall  pay  all of  the  costs  and  expenses  incurred  by it in
connection  with this  Agreement,  including the fees and  disbursements  of its
legal counsel and accountants. In the event the transactions contemplated herein
are consummated,  Newco will pay, or promptly reimburse,  all parties hereto for
the  reasonable  fees  and  disbursements  of  its  legal  counsel  incurred  in
connection  with the  negotiation  and entering  into of this  Agreement and the
other  contracts and  agreements  entered into in  connection  with the Closing.
Furthermore,  Newco agrees to reimburse the General Partner for the ordinary and
necessary  out-of-pocket  costs  incurred in preparing the 1997 and 1998 federal
income tax return of the Partnerships and the General Partner.

         Section 11.4 INVALID PROVISIONS.  If any provision of this Agreement is
held to be illegal,  invalid or unenforceable under present or future laws, such
provision  shall be fully  severable,  this  Agreement  shall be  construed  and
enforced  as if such  illegal,  invalid  or  unenforceable  provision  had never
comprised  a part of this  Agreement  and as if there was  substituted  in place
thereof a  provision  which  parallels  as closely as allowed by law the severed
provision,  and the remaining  provisions of this Agreement shall remain in full
force  and  effect  and  shall  not be  affected  by  the  illegal,  invalid  or
unenforceable provision or by its severance from this Agreement.

         Section  11.5  WAIVER.  No failure or delay on the part of any party in
exercising any right, power or privilege hereunder or under any of the documents
delivered in connection  with this  Agreement  shall operate as a waiver of such
right, power or privilege;  nor shall any single or partial exercise of any such
right,  power or privilege  preclude any other or future exercise thereof or the
exercise of any other right, power or privilege.

         Section  11.6  NOTICES.  Any notices  required or permitted to be given
under this Agreement (and, unless otherwise  expressly  provided therein,  under
any document delivered pursuant to this Agreement) shall be given in writing and
shall be deemed received (a) when delivered  personally or by courier service to
the relevant  party at its address as set forth below or (b) if sent by mail, on

the  additional  parties  listed  on  Appendix  I hereto  (each  an  "Additional
Purchaser"  and  collectively  the  "Additional  Purchasers").  Barton House and
Oakwell are sometimes collectively referred to herein as the "Partnerships."

                              PRELIMINARY STATEMENT

                             STATEMENT OF AGREEMENT

         NOW,  THEREFORE,  in consideration of the premises and mutual covenants
contained  herein and for other good,  valuable and binding  consideration,  the
receipt and  sufficiency of which are hereby  acknowledged,  the parties hereto,
intending to be legally bound hereby, agree as follows:

                                    ARTICLE I
                       DEFINITIONS; PERMISSIBLE TRANSFERS

         For  purposes  of this  Agreement,  each party  hereto,  other than the
Corporation,  is  hereinafter  sometimes  referred  to  as a  "Shareholder"  and
collectively  as the  "Shareholders."  For purposes of this Agreement all issued
and outstanding  capital stock of the  Corporation,  together with any hereafter
acquired,  whether common, preferred or otherwise, is hereinafter referred to as
the "Shares."

         The parties  hereto  acknowledge  and agree  that,  as of the date this
Agreement is initially entered into, the General Partner,  Bouchard,  Trevey and
the  Limited  Partner do not own any  Shares of the  Corporation.  However,  all
parties  hereto agree that any and all Shares  which either of the  Partnerships
obtains, either directly or indirectly, pursuant to the transactions consummated
in connection  with the execution of this Agreement,  that certain  Contribution
and Stock Purchase  Agreement dated effective January 1, 1998 (the "Contribution
Agreement")  or  any  other  document,   agreement  or  instrument  executed  in
connection with or contemplated 

                                       2
<PAGE>

by the Contribution Agreement, shall be promptly
transferred to the General Partner, Bouchard, Trevey and/or the Limited Partner,
as the case may be, and that neither of the  Partnerships  shall continue to own
any Shares as a result of this  Agreement,  the  Contribution  Agreement or such
other  agreements.  All  parties  hereto  agree that such  transfer of Shares by
either of the Partnerships to the General Partner,  Bouchard,  Trevey and/or the
Limited Partner,  in a single transaction,  shall be a permissible  transfer for
purposes of this Agreement. However, except for the transfer of Shares by Trevey
or  Bouchard  to  any  of  the  APS  Indemnified  Parties  (as  defined  in  the
Contribution  Agreement)  in  payment  of  an  indemnity  obligation  under  the
Contribution  Agreement (which shall also be a permissible transfer for purposes
hereof),  any other or further transfer,  assignment,  pledge,  hypothecation or
other alienation of any Shares or any interest  therein,  shall in every respect
be subject to the terms and  conditions of this  Agreement.  The parties  hereto
further  acknowledge  and agree that if,  upon the  permissible  transfer of all
Shares owned by the Partnerships to the other parties hereto as described above,
so that neither of the Partnerships own any Shares or any interest therein, each
of the Partnerships  shall no longer be bound by the terms of this Agreement and
shall no longer have any rights hereunder.

         The parties  hereto further  acknowledge  and agree that APS shall have
unrestricted  rights  to  freely  assign or  transfer  any of its  Shares to any
entity, the majority of whose voting equity securities is then owned directly or
indirectly by APS (an "APS Entity");  provided,  however,  that such entity must
sign a  counterpart  of this  Agreement,  and provided  further such entity must
transfer  any Shares  transferred  to it (and may do so without  any  consent or
option arising  hereunder) back to APS or another APS Entity (who must then sign
a  counterpart  hereof) in the event,  but prior to, such entity no longer being
majority owned, directly or indirectly, by APS.

                          RESTRICTIONS AGAINST TRANSFER

         Except as otherwise provided in this Agreement, a Shareholder shall not
transfer,  assign, pledge, hypothecate or in any way alienate any Shares, or any
interest  therein,  whether  voluntarily  or by  operation of law, or by gift or
otherwise,  without (a) the prior unanimous written consent of APS, Bouchard and
Trevey  or  (b)  in  the  case  of  a  pledge  or  hypothecation,   the  written
acknowledgment  of the lender,  in form and substance  reasonably  acceptable to
APS,  Bouchard  and Trevey,  that the lender will hold such Shares (or  interest
therein) subject to all of the terms and provisions of this Agreement,  and will
not foreclose upon or otherwise  transfer any such Shares,  or interest therein,
without  complying  with the  provisions  hereof,  including  those  relating to
options  to  purchase  the Shares by the other  parties  hereto.  Any  purported
transfer in  violation  of any  provision  of this  Agreement  shall be void and
ineffectual,  shall  not  operate  to  transfer  any  interest  or  title to the
purported  transferee and shall give the Corporation and the other  Shareholders
options to purchase such Shares in the manner and on the conditions  hereinafter
provided.

                                   ARTICLE III
                                     OPTIONS

         Section 3.1  Option Upon Voluntary Transfer.

         (a) Notice of Intention  to  Transfer.  Subject to (e) below and except
for a  transfer  of Shares by APS  pursuant  to Article I hereof,  no  voluntary
transfer  of any  Shares  or any  interest  therein,  shall,  without  the prior
unanimous  written  consent of APS,  Trevey and  Bouchard in each  instance,  be
allowed  for a  period  of two (2)  years  after  the  date  of this  Agreement.
Thereafter,  if a Shareholder intends to voluntarily  transfer any of its Shares
to any  person  other  than the  Corporation  and does not  obtain  the  written
consents  required  in Article II hereof,  the  Shareholder  shall give  written
notice to the Corporation and the other  Shareholders  stating (i) the intention
to transfer Shares, (ii) the number of Shares to be transferred, (iii) the name,
business and residence address of the proposed  transferee,  (iv) the nature and
amount of the consideration and (v) the other terms of the proposed sale.

         (b) Option to Purchase.  The  Corporation  shall have, and may exercise
within 60 days after  receipt of the notice of intent to transfer,  an option to
purchase all or any portion of the Shares owned by the transferring  Shareholder
for the  price  and upon the  other  terms  stated  in the  notice  of intent to
transfer.  If the Corporation  elects not to purchase all or any portion of such
Shares,  it shall,  prior to the  expiration of said 60-day  period,  notify the
other Shareholders in writing of its election,  and the other Shareholders shall
have, and may exercise within 30 days of 

                                       5
<PAGE>

receipt of the Corporation's  notice of
election,  an option to purchase such unpurchased Shares upon the same terms and
conditions.

         (c) Death Before  Closing.  If a  Shareholder  who proposed to transfer
Shares dies prior to the closing of the sale and purchase  contemplated  by this
Section,  the Shares of such deceased  Shareholder  shall be the subject of sale
and purchase under Section 3.3 hereof.

         (d) Allowable  Consideration.  All parties hereto acknowledge and agree
that it would be impractical to exercise an option to purchase  arising pursuant
to this  Section  whenever  the  proposed  consideration  to be  received by the
transferring  Shareholder is other than cash, cash  equivalents or an obligation
to pay cash by a person whose credit  worthiness  and  financial  status is such
that  performance  of  the  payment  obligation  would  be  reasonably  assured.
Therefore,  the parties agree that no transfer  shall be permitted and no option
shall arise pursuant to this Section  whenever the  consideration to be received
from the  proposed  transferee  is  other  than  cash,  cash  equivalents  or an
obligation to pay cash by a person whose credit  worthiness and financial status
is such that performance of the payment obligation would be reasonably assured.

         (e) Certain Exempted Voluntary Transfers. Notwithstanding the foregoing
or any other  provision of this  Agreement,  upon providing  written notice (and
without any requirement of consent),  as provided for herein, to the Corporation
and all other Shareholders: (i) any Shareholder may transfer Shares to any other
Shareholder,  at any time,  without  obtaining the written consent hereunder and
without giving rise to any Options provided for hereunder; (ii) Bouchard, Trevey
and the Limited Partner Permitted Assigns (as hereinafter  defined) may transfer


                                       6
<PAGE>

their Shares to their spouse,  children,  siblings,  parents or trust(s) created
exclusively for the benefit of their spouse, children,  siblings or parents, but
only to the extent of, and subject to, the provisions described below; and (iii)
the Limited  Partner may transfer its Shares to the following  parties (but only
to the extent of, and subject to, the provisions  described  below):  LTZ, Inc.,
Lebermann Investment,  J.V., Roger Minard, William Greehey, Stan McLelland,  and
Matt Mathias (the "Limited  Partner  Permitted  Assigns").  For purposes of this
subsection (e), "trust" shall be deemed to include a family limited partnership,
joint  venture or other entity,  as long as all of the equity  interests of such
family  limited  partnership,  joint  venture  or other  entity are owned by the
transferring Shareholder's spouse, children, siblings or parents.

         The  transfer  rights of Trevey and  Bouchard  described in clause (ii)
above  may only be made as  follows:  (A)  prior to  January  1,  2000,  no such
transfer shall be allowed and (B) during each calendar year beginning January 1,
2000,  Trevey and  Bouchard  shall each be entitled  to  transfer  the number of
Shares, whether received directly or indirectly,  representing up to twenty five
percent (25%) of his initial proportionate ownership interest in the Corporation
as  determined  immediately  following  the  consummation  of  all  transactions
contemplated  in  connection  with this  Agreement  (including  the  permissible
transfers  from the  Partnerships  under Article I hereof) and the  Contribution
Agreement, on a cumulative basis.

         Furthermore,  the  transferee  receiving  such Shares as  described  in
clause (ii) of the first  sentence of this  Section,  whether an  individual  or
trust, (X) shall grant (and maintain in place  thereafter) an irrevocable  proxy
to the transferring  Shareholder in form and substance reasonably  acceptable to
APS, (Y) shall  execute and deliver a  counterpart  of this  Agreement,  and (Z)
shall not receive by reason of such  transfer  any rights to benefits  from,  or
under,  the provisions for  registration  rights  contained in Article X of this
Agreement; provided, however, that the original transferring Shareholder (either
Trevey,  Bouchard or any of the Limited Partner Permitted  

                                       7
<PAGE>

Assigns,  as the case
may be), in their sole  discretion,  may elect (by notifying the  Corporation to
that effect in writing  during the 10-day  period for giving notice of intent to
include  Covered Shares in a registration  as  contemplated  in Section 10.1) to
allow the transferee hereunder to assume such registration rights, but only with
respect to such  Shares  described  in clause (ii) above and only as, and to the
extent, otherwise provided in Article X.

         Each of the Limited Partner  Permitted Assigns which may receive Shares
described in clause (iii) above,  whether an individual  or other entity,  shall
execute and deliver a counterpart of this Agreement and shall receive, by reason
of such transfer, registration rights pursuant to Article X of this Agreement.

         Section 3.2  Option Upon Certain Involuntary Transfers.

         (a) Exercise Event and Notice. The filing of a voluntary or involuntary
petition of  bankruptcy  by or on behalf of a  Shareholder,  an  assignment by a
Shareholder of any of its Shares, or of any right or interest  therein,  for the
benefit of creditors,  or the voluntary  transfer,  transfer by law or any other
transfer,  of any  Shares,  or of any  right or  interest  therein  (other  than
transfers governed by Article I, Article II, Section 3.1, Section 3.3 or Section
3.4 hereof), shall give the Corporation and the other Shareholders the option to
purchase the Shares of such bankrupt  Shareholder or such transferred  Shares as
provided  herein.  Upon the filing of a  voluntary  or  involuntary  petition of
bankruptcy by or on behalf of a Shareholder  or an assignment by  Shareholder of
any of its  Shares,  or of any right or  interest  therein,  for the  benefit of
creditors,  the Shareholder or its personal  representative  shall promptly give
written  notice  of  

                                       8
<PAGE>

such  occurrence  to  the  Corporation  and  to  the  other
Shareholders.  In the event of a transfer of Shares,  as  described  above,  the
Shareholder  transferring such Shares shall promptly give written notice of such
transfer to the Corporation and to the other Shareholders.

         (b) Option to Purchase.  The  Corporation  shall have, and may exercise
within 60 days after receipt of the notice of the applicable  exercise event, an
option to  purchase  all or any portion of the Shares  owned by the  bankrupt or
transferring  Shareholder  for the price and upon the  other  terms  hereinafter
provided.  If the Corporation  elects not to purchase all or any portion of such
Shares,  it shall,  prior to the  expiration of said 60-day  period,  notify the
other  Shareholders  in writing of its election.  The other  Shareholders  shall
have,  and may  exercise  within  thirty  (30) days of  receipt of the notice of
election,  an option to purchase such unpurchased  Shares for the price and upon
the other terms hereinafter provided.

         Section  3.3  Transfer  of  Shares  Upon  Death.  Upon  the  death of a
Shareholder,  any transfer of Shares of the deceased Shareholder pursuant to the
Shareholder's  last  will or the laws of  descent  and  distribution  shall be a
permitted transfer for purposes of this Agreement and shall not give rise to any
option to  purchase or require the  acquiror  to execute a  counterpart  of this
Agreement.

         Section 3.4 Option Upon Death of a Shareholder's Spouse, Termination of
Marital Relationship or Partition of Community Property.

         (a)  Death  of   Shareholder's   Spouse.   Each  Shareholder  and  each


                                       9
<PAGE>

Shareholder's  spouse  agree  that in the  event  the  spouse  of a  Shareholder
predeceases  such  Shareholder  and such  Shareholder  does not  succeed  by the
spouse's  last  will  and  testament  or by  operation  of law  to any  interest
(including,  without limitation, a community property interest) of the spouse in
the Shares,  such Shareholder  shall have, and may exercise within 60 days after
the death of the  spouse,  an  option  to  purchase  all or any  portion  of the
spouse's interest for the price and upon the other terms  hereinafter  provided.
If the  Shareholder  spouse  elects not to  purchase  all or any  portion of the
deceased spouse's interest, it shall, prior to expiration of said 60-day period,
notify the  Corporation  and the other  Shareholders in writing of its election.
The  Corporation  shall then have, and may exercise within 30 days of receipt of
the election, an option to purchase the unpurchased,  deceased spouse's interest
for the price and upon the other terms hereinafter  provided. If the Corporation
elects not to purchase all or any portion of the deceased spouse's interest,  it
shall, prior to expiration of said 30-day period,  notify the other Shareholders
in  writing of its  election  and the other  Shareholders  shall  have,  and may
exercise  within 30 days of  receipt  of  election,  an option to  purchase  the
unpurchased,  deceased  spouse's interest for the price and upon the other terms
hereinafter provided.

         (b)  Termination  of Marital  Relationship  or  Partition  of Community
Property. In the event a divorce,  annulment or other proceeding for termination
of the marital  relationship  is filed by or against a Shareholder,  or upon the
initiation  of any voluntary or  involuntary  attempt to partition the community
property  estate  between a Shareholder  and such  Shareholder's  spouse for any
reason,  the  Shareholder  shall promptly give written notice to the Corporation
and the other  Shareholders of such event.  The Shareholder  shall have, and may
exercise within sixty (60) days of giving of such notice,  an option to purchase
all or  any  portion  of the  spouse's  right  to or  

                                       10
<PAGE>

interest  in  such  Shares
(including without limitation any community  property  interest),  for the price
and upon the other terms hereinafter  provided. If the Shareholder elects not to
purchase  all or any  portion  of the  spouse's  interest,  it  shall,  prior to
expiration  of said  60-day  period,  notify the  Corporation  in writing of its
election and the  Corporation  shall have,  and may exercise  within thirty (30)
days of receipt of such election, an option to purchase the unpurchased spouse's
interest  for the price and upon the other terms  hereinafter  provided.  If the
Corporation  elects not to purchase all or any portion of the spouse's interest,
it  shall,  prior  to  expiration  of  said  30-day  period,  notify  the  other
Shareholders in writing of its election and the other  Shareholders  shall have,
and may exercise within thirty (30) days of receipt of such election,  an option
to purchase the unpurchased  spouse's  interest for the price and upon the other
terms hereinafter provided.

         Section 3.5  Alternate  Notices.  The failure of any person,  whether a
party to this  Agreement or  otherwise,  to give notice of the  occurrence of an
Exercise Event (as defined in Section 5.3 hereof) as  contemplated  herein shall
not operate to prevent the  creation of any option which would  otherwise  arise
pursuant to this Article.  Any party to this Agreement who has actual  knowledge
of the occurrence of an Exercise  Event may give the required  written notice of
the occurrence of an Exercise Event,  and upon the giving of such written notice
the  options  shall be created and become  exercisable  to the same extent as if
such notice was given by the party initially contemplated above.

                                   ARTICLE IV
                  EXERCISE OF OPTIONS; EFFECT OF NON-EXERCISE;
                                 CO-SALE RIGHTS

         Section 4.1 Manner of Exercise of Options.  All options  granted in, or
arising  pursuant to,  Article III hereof shall be exercised by a written notice
to that  effect  delivered  within the time  provided  for the  exercise  of the
option.

         Section  4.2  Complete  Exercise  of  Options.  The  holders of options
granted in, or arising pursuant to, Article III hereof must,  either alone or in
the  aggregate,  exercise the options in such a manner as to purchase all of the
Shares (or interest therein) subject to such options, and failure to do so shall
cause a forfeiture of the options.  Where one or more Shareholders  elect not to
exercise such options,  the other  Shareholders  shall be entitled to assume the
options not exercised on a pro rata basis pursuant to Section 4.3.

         Section 4.3 Multiple Option  Holders.  In cases where an option is held
by more than one Shareholder,  each purchasing  Shareholder shall be entitled to
purchase his or her  proportionate  share of the Shares subject to the option. A
Shareholder's proportionate share shall equal the total number of Shares subject
to the option  multiplied  by a fraction the numerator of which is the number of
Shares held by such Shareholder and the denominator of which shall be the number
of Shares held by all Shareholders electing to exercise the option.

         Section  4.4  Effect of  Non-Exercise  of  Options.  If the  holders of
options  granted or arising  pursuant to this  Agreement do not  exercise  their
options,  or such  options  are  forfeited,  as provided  herein,  the person or
persons  acquiring the Shares (or interest therein) that were the subject of the
options shall execute a counterpart  of this Agreement and become a party hereto
and shall  hold such  Shares  subject to all the terms and  conditions  provided
herein, and any transfer of such Shares (or interest therein) shall only be made
in accordance with the terms and conditions  provided  herein.  In the event the
person or persons  acquiring the Shares (or interest  therein) fail to execute a
counterpart of this Agreement and become a party hereto,  such transfer shall be
void and  ineffectual and shall not operate to transfer any interest or title to
the  purported  transferee,  and such  Shares  shall  thereafter  be  subject to
cancellation  and  extinguishment  by  the  Corporation,  without  consideration
therefor.  In addition,  in the event of a transfer subject to the provisions of
Article  III hereof,  upon the lapse or  forfeiture  of all the options  arising
pursuant to that Article,  the transferor shall have the right to effectuate the
transfer of Shares in  accordance  with the terms stated in the notice of intent
to transfer or notice of Exercise Event (as  applicable),  and the transferee of
such Shares shall  execute and become a party to this  Agreement  and shall hold
such  Shares  subject  to all of its terms  and  conditions.  Provided  further,
however, any such transfer of Shares shall be void and ineffectual and shall not
operate to transfer any interest or title to the  purported  transferee,  if (a)
for voluntary  transfers under Section 3.1 hereof,  the transfer is not upon the
terms or is not to the transferee  stated in the notice of intent to transfer or
(b) for all transfers giving rise to options  pursuant  hereto,  the transfer is
not closed within thirty (30) days of receipt of written  notice of the election
not to exercise,  or the  forfeiture of, all  applicable  options;  and upon the
occurrence  of  events  or  conditions  described  in (a) or (b) the  transferor


                                       13
<PAGE>

desiring to effect such transfer  must again comply with the notice,  option and
other  requirements  of this  Agreement  prior to any  transfer of any Shares or
interest therein.

         Section  4.5  Co-Sale  Rights.  In the  event of a  voluntary  transfer
pursuant to the  provisions  of Section 3.1  (except for  transfers  pursuant to
subsection (e) of Section 3.1) by Bouchard,  Trevey, APS or the Limited Partner,
the holders not exercising  their options granted  pursuant to Section 3.1 shall
be entitled to include,  upon the same terms and  conditions  as provided in the
notice required by Section 3.1(a), their Shares in such voluntary transfer, on a
pro rata basis based on the ratio of total  Shares  owned by those  having these
co-sale rights and the Shareholder receiving the voluntary transfer offer.

                                    ARTICLE V
                                 PURCHASE PRICE

         Section  5.1  Purchase  Price.  The  purchase  price  of  Shares  to be
purchased pursuant to options granted, held or exercised pursuant to Section 3.2
and  Section 3.4  hereof,  shall be the amount  calculated  in  accordance  with
Section 5.2 hereof.

         Section  5.2  Calculation  of  Purchase   Price.   When  determined  in
accordance  with this  Section,  the  purchase  price for Shares or any  portion
thereof or spouse's  interest therein shall be equal to an amount agreed upon by
the seller and the buyer or buyers  electing to purchase such Shares  hereunder.
In the event that no such  agreement is reached within thirty (30) days prior to
the closing of such purchase and sale,  the purchase price per Share shall equal
the  Book  Value  

                                       14
<PAGE>

(as  hereinafter  defined)  of the  Shares  to be  transferred
determined as of the Valuation Date (as hereinafter  defined).  However,  at the
written  request  of either the seller or any of the  proposed  purchasers,  the
purchase price shall equal the Appraised Value (as  hereinafter  defined) of the
Shares as of the Valuation Date,  reduced when necessary to reflect the purchase
of less than a one hundred  percent (100%)  interest in each of the Shares to be
transferred (for example:  reduced by one-half when a spouse's  interest is only
an undivided  one-half  community  property  interest in each of the Shares of a
Shareholder spouse). For purposes of this Agreement,  the "Book Value" per Share
shall be determined by subtracting  the total  liabilities of the Corporation as
of the  Valuation  Date  from the  total  assets  of the  Corporation  as of the
Valuation  Date,  and  dividing  such amount by the  aggregate  number of Shares
issued and  outstanding as of the Valuation  Date. Book Value per Share shall be
determined using the Corporation's  unaudited,  internally  generated  financial
statements  prepared on the accrual  basis of  accounting  consistent  with past
practices.  The Book Value per Share so computed shall be reduced when necessary
to reflect the purchase of less than a one hundred  percent  (100%)  interest in
each of the  Shares to be  transferred.  For  purposes  of this  Agreement,  the
"Appraised  Value" per Share  shall be the fair  market  value per Share which a
willing buyer would pay a willing seller for all issued and  outstanding  shares
of capital stock of the  Corporation  where neither is under any  compunction to
act (without any premium or discount for controlling interests, or lack thereof,
or lack of established market for such capital stock). The Appraised Value shall
be determined by a certified  business  appraiser,  selected by the Corporation,
that is a member of either the American  Society of  Appraisers or the Institute
of Business Appraisers;  but if a Shareholder  disagrees with such determination
that Shareholder may, at its expense,  have another certified business appraiser
that is a member of one or both of the above  named  professional  organizations


                                       15
<PAGE>

determine the value, and if the two appraisers  cannot agree upon a value,  they
shall mutually select a third certified business appraiser (that meets the above
described  membership  requirements)  who  shall,  together  with the  first two
appraisers,  determine  the value of the Shares by majority  vote.  The combined
expenses  of all  appraisals  shall  be paid  solely  by the  party  or  parties
requesting to utilize such method of determining the purchase price.

         Section 5.3 Certain  Definitions.  As used herein,  the term "Valuation
Date"  shall mean and refer to the end of the  calendar  quarter  preceding  the
Exercise Event. As used herein,  the term "Exercise  Event" shall mean and refer
to the event or  circumstance  described  in Article III hereof,  as a result of
which  the  Corporation  or a  Shareholder,  as the  case  may  be in the  first
instance, become entitled to exercise a purchase option hereunder.

                                   ARTICLE VI
                          PAYMENT OF THE PURCHASE PRICE

         Section 6.1 Payment.  Except as otherwise  provided in this  Agreement,
including Section 3.1 hereof, the purchase price for Shares to be purchased from
a selling party shall either: (a) be paid in cash at the closing;  or (b) at the
option of the  purchasing  party,  up to seventy  percent  (70%) of the purchase
price may be deferred with the remainder  paid in cash at the closing.  However,
option (b) of the  foregoing  sentence  shall not be  available  if the  selling
Shareholder  is the  Limited  Partner or any of the  Limited  Partner  Permitted
Assigns.

                                       16
<PAGE>

         Section 6.2 Promissory  Note. If the  purchasing  party elects to defer
part of the purchase  price by the execution and delivery of a promissory  note,
the deferred  portion of the price shall be evidenced by the promissory  note of
the  purchasing  party to the order of the selling  party  payable in sixty (60)
equal monthly  installments of principal and interest on or before the first day
of each  month  beginning  the month next  following  the date of  closing.  The
interest rate for such  installment  promissory note shall be equal to the prime
or base rate on corporate loans at large U.S. money center  commercial  banks as
published in the "Money Rates" column of the Wall Street  Journal on the date of
exercise of the option to purchase  (or,  if such option is not  exercised  on a
date on which such rate is published, the next following date on which such rate
is  published).  In no event shall the  interest  rate exceed the maximum  legal
interest rate then  prevailing for such  obligations in the state of Texas.  The
note  shall  be  secured  by a  first  lien  security  interest  in  the  Shares
transferred and the purchasing party shall deliver  certificates  evidencing the
Shares  to the  selling  party  and take such  further  action as is  reasonably
necessary to perfect the security interest.

                                   ARTICLE VII
                                   THE CLOSING

         Unless  otherwise  agreed by the  parties,  the closing of the sale and
purchase of Shares shall take place at the principal  offices of the Corporation
within  sixty  (60) days  after the  exercise  of any  option  provided  by this
Agreement.  Each party hereto (including the spouses of the Shareholders)  shall
bear its own transaction  costs,  including  legal and accounting  fees, if any,
attributable  to any transfer of Shares,  or any interest  therein,  pursuant to
this Agreement.  Upon 

                                       17
<PAGE>

the closing, the selling party shall deliver its Shares to
the purchaser free and clear of all liens and encumbrances, and shall deliver to
the  Corporation  its  resignation  and that of all of its nominees,  if any, as
officers  and  directors  of  the  Corporation  and  any  of  the  Corporation's
subsidiaries.  The  selling  party  shall  deliver  to the  purchasing  party at
closing,  all appropriate  documents of transfer,  including without  limitation
bills of sale, assignments or other instruments of conveyance. As a condition to
any  closing  of the sale and  purchase  of  Shares  (or any  interest  therein)
pursuant to this  Agreement:  (a) the selling party shall be  indemnified by the
purchasing  party (in a form  reasonably  satisfactory to the selling party) for
all the Corporation's  liabilities,  whether fixed or contingent, to lenders and
others,  incurred  prior to the closing of the  transaction,  (b) the purchasing
party and/or the Corporation shall cause the release of any personal guaranties,
either  directly  incurred  or assumed,  (i) which may have been  granted by the
selling party to the Corporation's  lenders or other creditors or the lenders or
other creditors of the  Partnerships  or the General  Partner whose  obligations
where assumed by the  Corporation or (ii) which may have otherwise been provided
by the selling party for the benefit of the Corporation,  and (c) if the selling
party  is  a  creditor  of  the   Corporation,   the   purchasing   party  shall
unconditionally  guarantee the debt of the  Corporation to the selling party and
execute  such  documents  and  instruments  of  guarantee as may be necessary in
connection therewith.  Furthermore,  and as a condition to closing, in the event
the selling  party owes any amounts to the  Corporation  at the time of closing,
such indebtedness  shall be paid in full by the selling party at or prior to the
closing,  or may be deducted from and offset  against the purchase  price by the
purchasing party, in the purchasing  party's sole discretion.  In the event of a
failure  to close as a  result  of the  non-satisfaction  of the  conditions  to
closing set forth herein,  this Agreement  shall remain in full force and effect
and all Shares shall remain subject to the restrictions contained herein and, in
addition,  the parties hereto 


                                       18
<PAGE>

shall be entitled to such other remedies as may be
available in the event the failure to close constitutes a breach hereof.

                                  ARTICLE VIII
                STRUCTURE OF BOARD OF DIRECTORS; MAJOR DECISIONS

         Each of the parties  hereto agrees to vote their Shares as necessary to
provide for the following.  The number of directors of the corporation  shall be
no fewer  than four (4) and no more than  seven  (7),  two (2) of which (the "BT
Designees")  shall be designated by George R. Bouchard  ("Bouchard") and John H.
Trevey  ("Trevey"),  and  two  (2) of  which  (the  "APS  Designees")  shall  be
designated,  subject to the  provisions  contained in the  Corporation's  Bylaws
regarding  the rights of the holders of  Preferred  Stock,  by APS.  The initial
directors  shall be four (4),  comprised  of the  initial BT  Designees  and the
initial APS Designees. Any increase in the number of directors shall require the
unanimous  consent of all  directors,  and shall be effected only be means of an
increase in the number of directors  from four to seven.  The  additional  three
directors (the "Group  Designees") shall initially be unanimously agreed upon by
Bouchard,  Trevey and APS.  Upon  written  notice from both  Bouchard and Trevey
(acting jointly) to the Corporation and other Shareholders,  Bouchard and Trevey
shall be entitled to replace  any two (2)  members of the Group  Designees  with
persons  mutually  acceptable to both  Bouchard and Trevey,  as indicated in the
written  notice (but who may not be officers or employees  of the  Corporation),
and the Shareholders  agree to vote their Shares to accomplish such replacement.
The parties all agree to vote their  Shares,  and to take such other and further
action  (including,  without  limitation,  the removal of Board members they may
designate  pursuant  hereto and  replacement  thereof) as 

                                       19
<PAGE>

necessary to amend the
Bylaws to increase  the size of the Board of  Directors to allow the addition of
the Group  Designees,  and to elect (or remove) the Group  Designees as provided
herein.  Until  February  1,  2001,  and  upon  written  notice  from APS to the
Corporation  and other  Shareholders,  APS shall be  entitled to  designate  any
member of the Board of Directors as Chairman of the Board,  and the Shareholders
agree  to vote  their  Shares  and to  take  such  other  actions  as  necessary
(including,  without  limitation,  the  removal  and  replacement  of any  other
existing  Chairman of the Board and any directors  they may  designate  pursuant
hereto) to cause the election and  retention in office of such  designee of APS.
The following acts or transactions by the Corporation will require,  in addition

                                   ARTICLE IX
                                PREFERRED RETURN

         For purposes hereof, the parties acknowledge and agree that APS and the
Additional  Purchasers,  in the aggregate,  initially  acquired their Shares for
$2,200,000  (the  "Initial  Capital  Contribution"),  allocated  amongst them as
provided in the Contribution Agreement. All parties hereto acknowledge and agree
that  upon  any  dissolution  or  liquidation  of the  Corporation,  APS and the
Additional  Purchasers (or their  successors in interest or assigns  pursuant to
any transfers  permitted  pursuant to this  Agreement),  in the aggregate,  will
receive from the Corporation in respect of the 760,000 shares of Preferred Stock
and Common  Stock  issued to them at the Closing and any shares of Common  Stock
issued without  consideration  in respect of any such shares,  to the extent the
Corporation has funds legally available therefor, an amount equal to the greater
of (a) that percentage (the "Applicable Percentage") of the cash and fair market
value of  property  and  other  assets  owned by the  Corporation  at that  time
determined  by  dividing  the sum of (i)  760,000  plus the  number of shares of
Preferred Stock and Common Stock issued without  consideration in respect of any
of the 760,000 shares of Preferred  Stock and Common Stock issued to APS and the
Additional  Purchasers  at the  Closing  by (ii) the  total  number of shares of
Preferred  Stock and  Common  Stock  outstanding,  with the amount of assets and
property so determined  reduced by the amount of all  liquidated  liabilities of
the Corporation and all reasonable  amounts (the "Contingency  Funds") held back
to make  provision for  unliquidated  liabilities  (excluding  the amount of any
indebtedness  assumed by, or assigned to, APS and the  Additional  Purchasers in
connection  with such  dissolution or liquidation) or (b) an amount equal to the

                                       25
<PAGE>

Initial Capital  Contribution  plus interest on the weighted average  unreturned
balance of their  Initial  Capital  Contribution  at the rate of twelve  percent
(12%) per annum, compounded annually, from the Closing Date; provided,  however,
that  all  distributions  made to  APS,  the  Additional  Purchasers  and  their
successors  in  interest,  with  respect  to their  ownership  interests  in the
Corporation,  shall be deducted in  calculating  the amount of  dissolution  and
liquidation  proceeds due such parties  under the  preferred  return  provisions
described  above and shall be considered  in  calculating  the weighted  average
unreturned balance of their Initial Capital  Contribution.  Upon satisfaction of
all liabilities for which the Contingency Funds were reserved, or upon any other
release  of  the  Contingency   Funds  no  longer   reserved  for   unliquidated
liabilities,  APS and the  Additional  Purchasers  shall receive the  Applicable
Percentage of the  Contingency  Funds not expended,  if any, in  satisfaction of
liabilities that were  unliquidated  when the Contingency  Funds were originally
reserved,  but only if all such payments from the Contingency  Funds would cause
the aggregate  amount due under clause (a) above to exceed the aggregate  amount
due under clause (b) above.

         All proceeds payable under this Article shall be allocated  amongst APS
and Additional Purchasers,  and their successors and assigns, pro rata, based on
their respective  percentage  ownership of Shares originally  acquired under the
Contribution  Agreement.  All  parties  hereto  agree to vote  their  Shares and
execute  and  deliver  such  additional  documents  and  instruments  as  may be
necessary to cause the foregoing  preferred return to be paid by the Corporation
to APS and the Additional  Purchasers as contemplated above.  Provided,  nothing
contained in this Section  shall  require that any party make any payment to the
Corporation, or execute any note, to enable the Corporation to make any payments
required under this Section.

                                       26
<PAGE>

         All parties hereto acknowledge and agree that the Corporation shall not
make any distributions, whether in cash or property, including dividends, to any
of the directors,  shareholders or parties hereto unless such  distributions are
made in strict  compliance with the terms of this Agreement,  the Bylaws and the
Contribution Agreement.

                                    ARTICLE X
                               REGISTRATION RIGHTS

         Section 10.1 Incidental  Registration Rights. Only the original parties
to this  Agreement  (other  than the  Corporation)  shall have the  registration
rights  granted  pursuant to this Article,  and it is expressly  understood  and
agreed that no Shareholder  who  subsequently  executes this  Agreement,  and no
permitted transferee of any Shareholder (other than (i) transferees of transfers
expressly provided for pursuant to Article I hereof, (ii) transferees  permitted
pursuant to the prior written consent  contemplated in Article II hereof wherein
such written consent also extends expressly to the registration  rights included
in this Article X hereof, (iii) transferees of Trevey,  Bouchard and the Limited
Partner  Permitted  Assigns  permitted  pursuant  to  clause  (ii) of the  first
sentence of Section 3.1(e) hereof,  if Trevey,  Bouchard or the Limited  Partner
Permitted  Assigns,  as  applicable,  give the written  authorization  to extend
registration  rights as  contemplated  in Section  3.1(e),  and (iv) the Limited
Partner  Permitted  Assigns expressly named in Section 3.1(e) hereof) shall have
any of the registration  rights provided by this Article,  regardless of whether
they execute and become bound by a counterpart of this  Agreement.  For purposes
of this Article X hereof,  the above  described  

                                       27
<PAGE>

persons and entities having the
registration  rights  described  herein  are  collectively  referred  to as  the
"Covered  Parties" and  individually  as a "Covered  Party." Each of the Covered
Parties shall have the incidental  registration rights and other rights provided
under this Article. The incidental registration rights described in this Article
shall  apply  with  respect to any and all  shares  owned by any of the  Covered
Parties;  and any reference in this Article to "Shares" shall be deemed to refer
to the Shares of the Covered  Parties only  (including  any Shares  subsequently
acquired by any Covered Parties).

         If the  Corporation  at any time proposes to register any of its common
stock under the Act for sale to the  public,  whether for its own account or for
the  account  of  other  security  holders  or  both  (except  with  respect  to
registration  statements  on Forms S-4 or S-8 or another form not  available for
registering  the Shares for sale to the public or in  connection  with  mergers,
acquisitions,  exchange offers,  dividend  reinvestment plans or stock option or
other employee benefit plans of the Corporation), it will give written notice to
the Covered Parties of its intention so to do, which notice shall include a list
of the jurisdictions in which the Corporation  intends to attempt to qualify the
common  stock  under the  applicable  state  securities  laws.  Upon the written
request of one or more Covered  Parties,  given within 10 days after  receipt of
any such notice, to register any of their Shares,  the Corporation will, subject
to the  limitations  and conditions  contained  herein,  use its best efforts to
cause the Shares as to which registration shall have been so requested ("Covered
Shares"),  pro  rata  between  the  Covered  Parties  in a  ratio  equal  to the
respective  number of Shares then owned and  requested to be registered by them,
or such other ratio as may have been agreed upon among the Covered  Parties,  to
be  included  in the  securities  to be  covered by the  registration  statement
proposed to be filed by the  Corporation,  all to the 

                                       28
<PAGE>

extent requisite to permit
the sale or other disposition by the Covered Parties; provided, however, that:

         (a) Each Covered  Party shall each have the right to request  inclusion
of its Shares (and have such Shares included) in two (2) registration statements
that are declared  effective by the  Securities  and  Exchange  Commission  (the
"Commission").

         (b) If, at any time after giving such written  notice of its  intention
to register any securities  and prior to the effective date of the  registration
statement filed in connection  with such  registration,  the  Corporation  shall
determine for any reason not to register any securities at all (and in fact does
not do so), the  Corporation  may, at its election,  give written notice of such
determination to the Covered Parties who made a request as hereinabove  provided
and thereupon the  Corporation  shall be relieved of its  obligation to register
any Shares in connection  with that proposed  registration;  provided,  however,
that any election by the  Corporation and the exercise of its rights pursuant to
this  subsection  shall not  otherwise  affect the rights  granted  herein as to
future registrations.

         (c) If such registration involves an underwritten offering, the Covered
Parties  requesting to be included in the  Corporation's  registration must sell
their Covered Shares to the underwriters selected by the Corporation on the same
terms and conditions as apply to the Corporation and other selling parties under
the registration statement (except as otherwise set forth herein).

         The number of Covered  Shares to be included in such an offering may be
reduced if and to the extent that the managing underwriter,  if any, shall be of
the opinion that such  inclusion  would  adversely  affect the  marketing of the
securities to be sold by the  Corporation  therein (pro rata between the Covered
Parties in a ratio  equal to the  respective  amounts of Covered  Shares held by
each).  Notwithstanding  anything to the contrary contained in this Section,  in
the event that there is an  underwritten  public  offering of  securities of the
Corporation pursuant to a registration covering Shares, and a Covered Party does
not elect to sell its Covered Shares to the  underwriters  of the  Corporation's
securities in connection  with such  offering,  such Covered Party shall refrain
from  selling  such  Covered  Shares  during the period of  distribution  of the
Corporation's  securities  by  such  underwriters,   the  period  in  which  the
underwriting  syndicate  participates in the after market and during any lock-up
period  requested  by such  underwriters;  provided,  however,  that the Covered
Parties shall, in any event, be entitled to sell their Shares  commencing on the
180th day after the effective date of such registration statement.

         Section 10.2 Registration  Procedures.  If and whenever the Corporation
is required by the provisions of this Article to effect the  registration of any
of the Covered Shares under the Act, the Corporation  will, as  expeditiously as
possible:

         (a)  prepare  and file with the  Commission  a  registration  statement
(which, in the case of an underwritten  public offering shall be on such form of
general  applicability as may be satisfactory to the managing  underwriter) with
respect to such  securities and use its best efforts to cause such  registration
statement  to become and  remain  effective  for the period of the  distribution
contemplated thereby (determined as hereinafter provided);

                                       30
<PAGE>

         (b)  prepare  and  file  with  the  Commission   such   amendments  and
supplements  to  such  registration   statement  and  the  prospectus  filed  in
connection  therewith as may be necessary  to keep such  registration  statement
effective for the period of distribution  and as may be necessary to comply with
the  provisions  of the Act with respect to the  disposition  of all  securities
covered by such  registration  statement in  accordance  with the  Corporation's
intended method of disposition set forth in such registration statement for such
period;

         (c) furnish to the Covered Parties, as applicable, and each underwriter
such number of copies of the registration  statement and the prospectus included
therein  (including each preliminary  prospectus) as they may reasonably request
in order to  facilitate  the public  sale or other  disposition  of the  Covered
Shares covered by such registration statement;

         (d) use its best  efforts to register  or qualify  the  Covered  Shares
covered by such registration  statement under the securities or blue sky laws of
such jurisdictions as the Covered Parties, as applicable,  or, in the case of an
underwritten public offering, the managing underwriter, shall reasonably request
(provided that the Corporation will not be required to (i) qualify  generally to
do  business in any  jurisdiction  where it would not  otherwise  be required to
qualify but for this  subsection,  (ii)  subject  itself to taxation in any such
jurisdiction  or  (iii)  consent  to  general  service  of  process  in any such
jurisdiction);

         (e) promptly  notify the Covered  Parties,  as  applicable,  under such
registration  statement  and each  underwriter,  at any time  when a  prospectus
relating thereto is required to be 

                                       31
<PAGE>

delivered under the Act when it becomes aware
of the happening of any event as a result of which the  prospectus  contained in
such registration  statement, as then in effect, includes an untrue statement of
a  material  fact or omits to state  any  material  fact  required  to be stated
therein or necessary to make the statements  contained therein not misleading in
light of the circumstances then existing;

         (f) use its best efforts (if the offering is  underwritten) to furnish,
at the  request of the  Covered  Parties,  as  applicable,  on the date that the
Covered  Shares are  delivered  to the  underwriters  for sale  pursuant to such
registration:  (i) an  opinion  dated  such  date of  counsel  representing  the
Corporation for the purposes of such registration, addressed to the underwriters
and in customary  form and covering such matters as are  customarily  covered by
opinions  of counsel  in similar  registrations  and as may be  required  in the
underwriting  agreement relating thereto,  as may reasonably be requested by the
underwriters or by the Covered Parties, as applicable; and (ii) a comfort letter
dated  such  date  from  the  independent  public  accountants  retained  by the
Corporation,  addressed to the underwriters, in customary form and covering such
matters  as  are  customarily   covered  by  such  comfort  letters  in  similar
registrations  and as may be required  in the  underwriting  agreement  relating
thereto,  as such  underwriters  or the  Covered  Parties,  as  applicable,  may
reasonably request; and

         (g)  make  available  for  inspection  by  the  Covered  Parties,   any
underwriter  participating  in any  distribution  pursuant to such  registration
statement,  and any attorney,  accountant or other agent retained by the Covered
Parties or  underwriter,  all financial and other records,  pertinent  corporate
documents  and  properties  of the  Corporation,  and  cause  the  Corporation's


                                       32
<PAGE>

officers, directors and employees to supply all information reasonably requested
by any  such  Covered  Party,  underwriter,  attorney,  accountant  or  agent in
connection with such registration statement.

         For  purposes  of  paragraphs   (a)  and  (b)  above,   the  period  of
distribution  of Covered  Shares in an  underwritten  public  offering  shall be
deemed to extend until each  underwriter  has completed the  distribution of all
securities  purchased by it, and the period of distribution of Covered Shares in
any other  registration  shall be deemed to extend until the earlier of the sale
of all Covered Shares or 180 days after the effective date thereof.

         In connection with each registration hereunder, the Covered Parties, as
applicable,  will furnish to the  Corporation in writing such  information  with
respect  to  themselves  and the  proposed  distribution  by them  as  shall  be
requested  by the  Corporation  in order to assure  compliance  with federal and
applicable state securities laws.

         In connection with each  registration  covering an underwritten  public
offering,  the  Corporation  agrees to enter into a written  agreement  with the
managing  underwriter  selected in the manner  herein  provided in such form and
containing such provisions as are customary in the securities  business for such
an arrangement  between major  underwriters  and companies of the  Corporation's
size and investment stature;  provided that such agreement shall not contain any
such  provision  applicable to the  Corporation  that is  inconsistent  with the
provisions hereof and, further,  provided that the time and place of the closing
under such agreement  shall be as mutually  agreed upon between the  Corporation
and such managing underwriter.

                                       33

         The  Corporation  will not be  obligated to include any Shares owned by
the Covered Parties requesting that a proposed  registration include such Shares
if the Corporation delivers to the requesting Covered Parties the opinion of the
Corporation's  counsel  (such  counsel and the form of such opinion  having been
approved by the Covered  Parties in their  reasonable  discretion) to the effect
that  the  requested  registration  is  not  required  to  permit  the  proposed
disposition  or any resale of such Shares,  without  restrictions  on subsequent
transfer,  under the Act,  which  opinion may be furnished to and relied upon by
any broker through which the Covered Parties may elect to sell any Shares.

         Section  10.3  Conditions  to  Obligation  to  Register   Shares.   The
Corporation's  obligations  under this Article shall be subject to the following
limitations and conditions:

         (a) The Corporation  shall have received from the Covered  Parties,  as
applicable,  all such information as the Corporation may reasonably request from
the  Covered  Parties  concerning  each of them  and each of  their  methods  of
distribution  of the Covered Shares to enable the  Corporation to include in the
registration statement all material facts required to be disclosed therein.

         (b) Any request by the Covered  Parties  pursuant to this Agreement for
registration  of the  offering,  sale and delivery of Shares shall  provide that
each Covered  Party,  as  applicable,  (i) has a present  intention to sell such
Shares;  (ii)  agrees to execute all  consents,  powers of  attorneys  and other
documents  required  in order to cause  such  registration  statement  to become


                                       34
<PAGE>

effective;  (iii)  agrees,  if  the  offering  is at the  market,  to  give  the
Corporation written notice of the first bona fide offering of such Shares and to
use the  prospectus  forming a part of such  registration  statement  only for a
period of 180 days after the effective date of the registration statement unless
the  offering  is  pursuant to a  continuous  registration  pursuant to Rule 415
promulgated  under the Act; (iv) subject to adverse events regarding the selling
price of the Shares,  agrees to utilize its proposed  method of  distribution of
the registered securities; and (v) agrees to promptly notify the Corporation and
each underwriter, if any, with regard to any registration statement, at any time
when it  becomes  aware of the  happening  of any event as a result of which any
prospectus  contained in such  registration  statement that has been provided to
the Covered Party includes an untrue  statement of a material fact regarding the
Covered  Party or omits to state a material  fact  regarding  the Covered  Party
required to be stated  therein or  necessary  to make the  statements  contained
therein   regarding   such  Covered  Party  not   misleading  in  light  of  the
circumstances then existing.

         Section  10.4  Distribution   Arrangements.   Each  Covered  Party,  as
applicable,  agrees that,  in disposing of its Shares in the  registered  public
offering,  such Covered Party will comply with applicable  rules  promulgated by
the Commission.

         Section 10.5  Expenses.  All expenses  incurred by the  Corporation  in
preparing  and complying  with a  registration  covering any Shares,  including,
without  limitation,  all registration,  qualification and filing fees, blue sky
fees and expenses,  printing  expenses,  fees and disbursements of legal counsel
and independent public accountants for the Corporation,  the reasonable fees and
expenses of one law firm serving as legal counsel for the participating  Covered


                                       36
<PAGE>

Parties, fees of the National Association of Securities Dealers,  Inc., transfer
taxes,  escrow  fees,  fees of  transfer  agents  and  registrars  and  costs of
insurance,  but excluding any Selling Expenses,  are herein called "Registration
Expenses." All underwriting  discounts and selling commissions applicable to the
sale of Covered Shares are herein called "Selling Expenses."

         The Corporation shall pay all Registration  Expenses in connection with
any  registration  statement.  All  Selling  Expenses  in  connection  with  any
registration  statement  shall be borne by each  participating  Covered Party in
proportion to the number of Covered Shares sold by each.

         Section 10.6 Indemnification.  In the event of a registration of any of
the Covered Shares under the Securities Act, the Corporation shall indemnify and
hold harmless the Covered Party, as applicable,  thereunder and each underwriter
and each associate, if any, of the Covered Parties, or underwriter,  against any
losses, claims,  damages or liabilities,  joint or several, to which the Covered
Parties, or underwriter or associate thereof may become subject under the Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect  thereof) arise out of or are based upon any untrue statement or alleged
untrue  statement of any material fact contained in any  registration  statement
under which such Covered Shares were  registered  under the Act, any preliminary
prospectus or final prospectus contained therein, or any amendment or supplement
thereof,  or arise out of or are based upon the omission or alleged  omission to
state therein a material fact required to be stated therein or necessary to make
the statements  therein not  misleading,  or any violation by the Corporation of
any rule or regulation  promulgated  under the Act applicable to the Corporation
and relating to action or inaction by 

                                       36
<PAGE>

the  Corporation  in  connection  with any
such  registration,  and shall reimburse the Covered  Parties,  each underwriter
and/or associate thereof 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 Corporation will not be liable
in any such  case if and to the  extent  that any such  loss,  claim,  damage or
liability  arises out of or is based upon an untrue  statement or alleged untrue
statement or omission or alleged  omission made in conformity  with  information
furnished by the Covered Parties,  each underwriter  and/or associate thereof in
writing specifically for use in such registration statement or prospectus.

         In the event of a  registration  of any of the Covered Shares under the
Act, each of the Covered Parties, as applicable, severally and not jointly, will
indemnify and hold harmless the Corporation and its affiliates, if any, and each
underwriter  and each associate of any underwriter  against all losses,  claims,
damages or  liabilities,  joint or  several,  to which the  Corporation  or such
underwriter or associate may become subject under the Act or otherwise,  insofar
as such losses,  claims,  damages or liabilities (or actions in respect thereof)
arise out of or are based upon any untrue  statement or alleged untrue statement
of any material fact contained in the  registration  statement  under which such
Covered  Shares were  registered  under the Act, any  preliminary  prospectus or
final prospectus  contained therein,  or any amendment or supplement thereof, or
arise out of or are based upon the omission or alleged omission to state therein
a  material  fact  required  to be  stated  therein  or  necessary  to make  the
statements  therein not  misleading,  and will reimburse the  Corporation,  each
underwriter and/or associate thereof 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 a Covered Party will


                                       37
<PAGE>

be liable  hereunder  in any such case if and only to the  extent  that any such
loss,  claim,  damage  or  liability  arises  out of or is based  upon an untrue
statement or alleged  untrue  statement or omission or alleged  omission made in
reliance  upon and in  conformity  with  information  pertaining to such Covered
Party,   furnished  in  writing  to  the   Corporation  by  that  Covered  Party
specifically for use in such registration statement or prospectus;  and provided
further,  however,  that the liability of any Covered Party  hereunder  shall be
limited to the proportion of any such loss, claim, damage,  liability or expense
that is equal to the proportion that the public offering price of Covered Shares
sold by such Covered Party, under such registration statement bears to the total
public offering price of all securities sold  thereunder,  but not to exceed the
proceeds  received by such Covered Party from the sale of Covered Shares covered
by such registration statement.

         Promptly after receipt by an indemnified  party  hereunder of notice of
the  commencement  of any action,  such  indemnified  party shall, if a claim in
respect thereof is to be made against the indemnifying  party hereunder,  notify
the  indemnifying  party in writing  thereof,  but the omission so to notify the
indemnifying  party shall not relieve it from any  liability  it may have to any
indemnified  party other than under this Section.  In case any such action shall
be brought  against any indemnified  party and it shall notify the  indemnifying
party of the commencement  thereof,  the indemnifying party shall be entitled to
participate  in and, to the extent it shall wish,  to assume and  undertake  the
defense thereof with counsel reasonably  satisfactory to such indemnified party,
and, after notice from the indemnifying  party to such indemnified  party of its
election so to assume and undertake the defense thereof,  the indemnifying party
shall not be liable to such  indemnified  party under this Section for any legal
expenses  subsequently incurred by such indemnified party in connection with the
defense thereof other than reasonable costs of 

                                       38
<PAGE>

investigation and of liaison with
counsel so elected; provided, however that, if the defendants in any such action
include  both  the  indemnified  party  and the  indemnifying  party  and if the
interests of the indemnified party reasonably may be deemed to conflict with the
interests of the indemnifying  party, the indemnified party shall have the right
to  select  separate  counsel  and  to  assume  its  defense  and  otherwise  to
participate  in the defense of such  action,  with the expenses and fees of such
separate  counsel  and  other  expenses  related  to  such  participation  to be
reimbursed by the indemnifying  party as incurred.  The indemnifying  party will
not be subject to any settlement  made without its consent,  which consent shall
not be unreasonably withheld. The indemnifying party will pay to the indemnified
party all sums due hereunder within 10 days of a final  non-appealable  judgment
or pursuant to the terms of a settlement agreement.

         Section 10.7  Limitation on Subsequent  Registration  Rights.  From and
after  the date of this  Agreement,  the  Corporation  shall  not,  without  the
unanimous  written consent of APS,  Trevey and Bouchard in each instance,  enter
into any agreement  with any holder or  prospective  holder of any securities of
the  Corporation  (nor shall the  Corporation,  in the absence of any such prior
agreement,  permit  any such  holder or  prospective  holder)  to  include  such
securities  in any  registration  contemplated  by  this  Agreement  other  than
incidental  (non-demand)  registration rights that are expressly  subordinate to
those granted the Covered Parties in this Agreement.

                            FUTURE EQUITY FINANCINGS

         Section 13.1 Right of First Refusal. Each party to this Agreement shall
be  entitled  to a right of first  refusal  in the  event  that  APS,  Trevey or
Bouchard  participate  in  any  future  equity  financing  by  the  Corporation,
including  any  instrument or security  convertible  into,  or  exchangeable  or
exercisable  for,  any  equity  ownership  interest  of  the  Corporation.   The
Corporation  shall,  not less  than 30 days  prior to the  consummation  of such
equity  financing,  notify  the  Shareholders  in  writing  of the  contemplated
transaction, including the terms and conditions of the issuance of capital stock
contemplated thereunder. Each Shareholder shall have, and may exercise within 15
days of receipt of such  notice,  a right to  purchase,  upon the same terms and
conditions,  that  proportion of such capital  stock equal to its  proportionate
ownership of the  Corporation as determined on the date of dispatch of notice of
such  transaction.  Each  Shareholder  choosing  to  participate  in such equity
financing  must exercise to the fullest  extent the rights  granted  pursuant to
this Section.  The exercise or  non-exercise  of any rights arising  pursuant to
this  Section  shall be  governed  by (and  treated in a like  manner to options
under) the  provisions  of Article IV hereof.  Payment for any shares of capital
stock purchased pursuant to this Section shall be in cash at the closing.

         Section 13.2  Limitations on Right of First Refusal.  The provisions of
this Article shall not apply to (a) any issuance of stock or options pursuant to
any stock option or stock purchase plan properly adopted and administered by the
Corporation  pursuant to this Agreement and the  Corporation's  Bylaws,  (b) any
issuance of stock,  stock purchase  rights,  options,  stock warrants or similar


                                       42

rights validly issued by the Corporation to any party hereto as compensation for
services, for providing guarantees of Corporation obligations,  or otherwise not
in connection with the Corporation  raising  additional cash through the sale of
equity  interests,  or (c) any  transaction  by the  Corporation  entirely  with
unrelated third parties.

                         BOARD MEETING ATTENDANCE RIGHTS

         Section  14.1  Observer.  According  to the terms of and subject to the
conditions  contained in this Article,  the Limited Partner shall be entitled to
designate not more than one individual (the  "Observer") who shall be allowed to
attend  meetings of the Board of Directors of the  Corporation (or listen in the
case of telephonic meetings).  The Limited Partner must select the Observer from
the following individuals: Lowell Lebermann, Roger Minard, William Greehey, Stan
McLelland or Matt Mathias.

         Section 14.2 Conditions,  Terms and Limitations.  The Limited Partner's
and the  Observer's  rights  under  this  Article  shall  be  conditional  upon,
qualified by, or subject to the following:

         (a) the  Observer  shall  not,  on  account  of being the  Observer  or
attending  any meeting of the Board of Directors,  be entitled to  compensation,
reimbursement, or indemnification of any kind from the Corporation or any party;

                                       43
<PAGE>

         (b) the  Observer  shall  use his  best  efforts  to  comply  with  any
reasonable demand or directive of the Chairman of the Board or other officer who
shall preside at and govern meetings of the Board of Directors;

         (c) the  Observer  shall not be  entitled to any vote on any matter and
shall comply with the rules of order and decorum as established by the presiding
officer,  which  may be  Robert's  Rules  of  Order,  and  which  are  generally
applicable to all parties at such meeting;

         (d) the Observer shall not be entitled to delay any meeting  regardless
of  circumstances,  and  the  presiding  officer  shall  have no  obligation  to
accommodate or consider any such request; and

         (e)  in  the  event  the  Observer  fails  to  comply  with  all of the
conditions,  terms and qualifications  hereunder,  the Observer may be required,
upon request from the presiding officer, to leave or not attend the meeting.

         Section 14.3  Confidentiality.  Prior to  attending  any meeting of the
Board  of  Directors,  the  Observer  must  execute,  in his  or her  individual
capacity,   a  confidentiality   agreement  in  form  and  substance  reasonably
acceptable  to  Corporation  and its counsel.  Pursuant to such  agreement,  the
Observer shall be prohibited from disclosing,  divulging, revealing or using any
Proprietary  Information (as defined in the Contribution  Agreement)  except for
the sole  purpose of  informing  the Limited  Partner  and the  Limited  Partner
Permitted Assigns of the Corporation's  affairs and of the activities  occurring
during the meetings  observed or pursuant to one of the  exceptions set forth in


                                       44
<PAGE>

the Contribution  Agreement.  All of the rights granted pursuant to this Article
XIV shall be forever  forfeited in the event that (a) any Observer  breaches any
of the  conditions  of this  Article  XIV,  or (b)  any  Observer  breaches  any
provision  of the  confidentiality  agreement  entered  into  pursuant  to  this
Section.  Any breach by any Observer of the  confidentiality  agreement required
under this Section shall also  constitute a breach by the Limited Partner of its
obligations  with  respect to  confidentiality  arising  under the  Contribution
Agreement.

         Section  14.4  Notice.  On  or  before  January  1 of  each  year,  the
Corporation  will, in writing,  provide the Limited Partner with the anticipated
dates  (subject  to change) of the  regular  meetings,  if any,  of the Board of
Directors for the following year (the "Annual  Meeting  Notice").  Within thirty
(30) days after receipt of the Annual Meeting  Notice,  the Limited Partner must
notify the Corporation of the name,  address,  facsimile number and phone number

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 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.  Except as  otherwise  expressly  provided  in this
Agreement  and in the  Note,  Deed of Trust  and  Security  Agreement,  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.

         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

                                       8
<PAGE>

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.

         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

appraisers   and  any  other  persons   deemed   necessary  by  Lender  to  such
investigation.

or by Lender and any of the  parties  listed on  Appendix I to the  Shareholders
Agreement ("Lender  Parties") or to any Lender Parties.  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.

         8.16 REQUIRED CONSENTS AND APPROVALS. Any consent or approval of Lender
required  hereunder  or under any other Loan  Document  executed  in  connection
herewith shall not be required,  or shall be deemed satisfied,  in the event (a)
approval  is required  of at least one of the APS  Designees  (as defined in the
Shareholders  Agreement)  under the Shareholders  Agreement,  and such approval,
together  with the overall  approval of the Board of Directors of Borrower,  has
been so  obtained,  or (b) such  action,  inaction  or  request by  Borrower  is
expressly  permitted,  without any  requirement of approval of Lender or any APS
Designee, under the Shareholders Agreement.

BORROWER:  Barton Acquisition, Inc., a Texas corporation

BORROWER'S  ADDRESS FOR NOTICE:  1301 Capital of Texas  Highway,  Suite  C-300, 
                                 Austin,  Texas  78746,  Attention:
John H. Trevey

LENDER:  American Physicians Service Group, Inc., a Texas corporation

LENDER'S ADDRESS FOR PAYMENT:   1301 Capital of Texas Highway, Suite C-300, 
                                Austin, Texas  78746

PRINCIPAL AMOUNT:  Two Million Four Hundred Thousand Dollars and No/100 Dollars 
                   ($2,400,000.00)

INTEREST RATE:  Ten Percent (10.0%)

PAYMENT  TERMS:  Interest  only on the  unpaid  balance  of this Note is due and
payable  quarterly,  beginning  June  1,  1998,  and  continuing  regularly  and
quarterly  thereafter on or before the first day of March,  June,  September and
December of each year,  until January 1, 2003 (the  "Maturity  Date"),  when the
outstanding  principal balance and all accrued interest shall be due and payable
in full.  Interest  will be  calculated on the unpaid  principal  balance.  Each
payment will be credited first to the 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 of the Loan Agreement  between  Borrower and Lender of even
date  herewith,  all or any portion of the Principal  Amount of this Note may be
borrowed, paid, prepaid, repaid, and reborrowed,  from time to time prior to the
Maturity  Date and in accordance  with the Loan  Documents.  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
exists  under  this Note or any Loan  Document,  then  Lender  shall be under no
obligation to make any advance under this Note.

LOAN AGREEMENT:  This Note is executed  pursuant to and is governed by the terms
of the Loan Agreement of even date herewith, executed by Borrower and Lender, as
amended (collectively, the "Loan Agreement").

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.  Interest  shall be calculated on the amount of each advance
of the Principal Amount of this Note from the date of each such advance.
<PAGE>

         (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
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

         (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

all of the  other  parties  liable  for  the  payment  of  this  Note,  such  as

         (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 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

fixtures.

incorporated  herein by reference or at its principal place of business.  Debtor

         3.9  Perfection.  Upon the filing of the UCC financing  statements with
the  Office of the Texas  Secretary  of State and in the  offices  of the County
Clerks of Bexar, Fort Bend and Travis Counties,  Texas, and upon Secured 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,  subject
only to those  liens  and  security  interests  expressly  permitted  under  the
Shareholders   Agreement  or   Contribution   Agreement   ("Permitted   Security
Interests").  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
Permitted  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
the time of the execution of this Agreement,  (i) Debtor is and will be solvent,
(ii) the fair  saleable  value of Debtor's  assets  exceeds and will continue to
exceed Debtor's liabilities (both fixed and contingent),  (iii) Debtor is paying
and will continue to be able to pay its debts as they mature, and (iv) if Debtor
is not an individual,  Debtor has and will have  sufficient  capital to carry on
Debtor's businesses and all businesses in which Debtor is about to engage.

                                   ARTICLE IV
                               DEBTOR'S COVENANTS

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,  other than
persons holding a Permitted Security Interest, at any time claiming any interest
therein adverse to Secured Party. Debtor shall keep the Collateral free from all
liens and  security  interests  except  those  for  taxes not yet due,  Security
Interest and the Permitted Security Interests.

         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 

                                       3
<PAGE>

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.
                  

         4.5 Secured  Party's  Costs.  Debtor  shall pay all costs  necessary to
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.  Secured  Party's rights  hereunder  shall be subordinate to and not
interfere with persons holding a Permitted Security Interest.

         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

                                       4
<PAGE>

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.

         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.

                                       5
<PAGE>

         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 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

                                       6
<PAGE>

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.

                                    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 of 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

                  (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(d) above.

                                   ARTICLE VI
                                     DEFAULT

         6.1 Events of Default.  The  following are events of default under this
Agreement  after  thirty  (30)  days'  written  notice  to  Debtor  ("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;

                                       7
<PAGE>

                  (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) sale,  encumbrance,  or transfer which is not permitted by
the  Contribution  Agreement or the  Shareholders  Agreeement;  or 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;

                  (f)      levy on, seizure, or attachment of any property of 
                           Debtor in excess of $50,000; or

                  (g)      a judgment against Debtor in excess of $250,000 
                           becomes final and is not covered by Debtor's 
                           insurance.

         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 provided herein, 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. Unless the Collateral
is  perishable  or  threatens  to  decline  speedily  in  value  or is of a type
customarily  sold  on a  recognized  market,  Secured  Party  will  give  Debtor
reasonable  notice of the time and place of any  public  sale  thereof or of the
time after which any private sale or other intended disposition thereof is to be
made. Expenses of retaking,  holding,  preparing for sale, selling,  leasing, or
the like shall 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  

                                       8
<PAGE>

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. Notice shall be deemed reasonable if mailed postage prepaid

                            PARTICIPATION AGREEMENT


         This PARTICIPATION  AGREEMENT (this "Agreement") is made as of this 
16th day of March, 1998, by and between American  Physicians Service Group, Inc.
, a Texas corporation  ("Seller"),  and the  undersigned  under the  heading,  
"Purchaser" ("Purchaser"), (Seller and each Purchaser are referred to herein 
separately as a "Participant" and collectively, as "Participants").

                              W I T N E S S E T H :

         WHEREAS,  Seller  has made or will  make a line of  credit  loan in the
maximum principal amount of Two Million Four Hundred Thousand and No/100 DOLLARS
($2,400,000) to Barton Acquisition,  Inc., a Texas corporation (the "Borrower"),
which loan shall be secured by a lien on all Borrower's assets including certain
real property located in Bexar,  Fort Bend and Travis  Counties,  Texas, as more
fully set forth on Exhibit "A" attached  hereto,  together  with all  equipment,
fixtures and personal property located thereon (the "Property"); and

         WHEREAS,  in  connection  with the  making of the line of credit  loan,
Borrower has executed or will execute and deliver the loan  documents  set forth
in the  schedule  attached  hereto,  marked  Exhibit "B", and hereby made a part
hereof (the "Loan Documents"); and

         WHEREAS,  Seller is duly  authorized  to sell  participation  shares in
loans originated by it and the participation created hereby is eligible for such
sale; and

         WHEREAS,  Purchaser  further  desires  to  participate  in  owning  the
evidences of the Loan and the security  therefor,  with Seller  serving as agent
and trustee for Purchaser in certain respects as hereinafter set forth.

         NOW,  THEREFORE,  in consideration of the mutual covenants  hereinafter
set forth and other good and valuable consideration,  receipt of which is hereby
acknowledged, the parties hereto agree as follows:

         1.       AGREEMENT FOR PURCHASE OF THE PARTICIPATION.

                  a. By its execution of this Agreement and in  consideration of
the mutual  covenants  herein set  forth,  Purchaser  does  hereby  purchase  an
undivided  interest  (the   "Participation"),   the  percentage  of  which  (the
"Percentage  Interest") shall be calculated as set forth in Section 2 hereof, in
(i) all of Seller's  loans and other  extensions of credit to or for the benefit
of Borrower under the Loan  Documents (all loans and other  extensions of credit
are  hereinafter  referred to as the "Loan"),  (ii) all existing and future real
and personal  property and interests  therein  securing the Loan,  including the
Property  ("Collateral"),  (iii) all existing and future claims against  persons
liable for the Loan ("Guaranty Claims"). The Participation includes a Percentage
Interest  in all  amounts,  other than those  amounts,  if any,  which are to be
retained by Seller or otherwise  allocated  to  Purchaser or Seller  pursuant to
Sections 4, 5 and 13 hereof, which are received by Seller on account of the Loan
("Payments"),  whether from (i) Borrower, (ii) the Collateral,  (iii) guarantors
or others  obligated to Seller with respect to the Loan (an "Obligor"),  or (iv)
any other  source,  including,  without  limitation,  recovery  from  litigation
without  limitation,  recovery from any setoff of Borrower's  accounts deposited
with  Seller,  proceeds  of title  insurance  claims,  other  insurance  claims,
condemnation  awards or recovery from  litigation.  Purchaser  acknowledges  and
understands  the  liens  and  security  interests  against  the  Collateral  are
secondary and inferior to other substantial loans to third party lenders.
<PAGE>

                  b.  PARTICIPATION.   Purchaser  has  advanced  to  Seller  its
respective  Contribution  Percentage,  as defined in Section 2 hereof,  of funds
advanced,  or to be advanced, by Seller to Borrower pursuant to the Loan. Seller
shall deposit all Contribution Percentages, to the extent not initially advanced
under the Loan,  into an escrow account with Seller ("Escrow  Account").  Seller
shall invest the funds in the Escrow  Account at its discretion and any interest
earned  thereon  shall be held on each  Purchaser's  behalf in their  respective
Contribution  Interest.  Seller shall,  from time to time,  pay to Purchaser all
amounts in which Purchaser has an interest in the manner herein provided.

                  c. NATURE OF RELATIONSHIP.  The relationship between Purchaser
and  Seller  is and  shall  be that of a  purchaser  and  seller  of a  property
interest, respectively,  (i.e., an outright purchase and sale of assets being an
assignment of a partial  interest in the Loan,  the  Collateral and the Guaranty
Claims)  and not a  creditor-debtor,  partner,  or  joint  venture  relationship
provided that any documents, monies or other property received, retained or held
by Seller for Purchaser shall be held by Seller in trust for Purchaser.

                  d.   SERVICING   COMPENSATION.   Seller   shall   receive   no
compensation for servicing the Loan.

         2.  PERCENTAGE  INTEREST;  CONTRIBUTION  PERCENTAGE;  MAXIMUM AMOUNT OF
PURCHASER'S  COMMITMENT.  As used herein, the term "Percentage  Interest",  when
used  with  respect  to  any  Purchaser,  shall  mean  the  percentage  by  each
Purchaser's  name as set forth and  described  in Exhibit  "D"  attached  hereto
multiplied by the aggregate amount of principal  advanced and outstanding at any
particular time. As used herein, the term "Percentage Interest",  when used with
respect to Seller, shall mean the remaining percentage of eighty-nine and 20/100
percent (89.20%) of the aggregate amount of outstanding  principal  advanced and
outstanding,  and from time to time as each such respective  Percentage Interest
bears  at  such  time  to the  aggregate  principal  balance  of the  Loan  then
outstanding.  As used herein,  the term  "Contribution  Percentage" of Purchaser
shall mean the same as the Percentage Interest.

         3.       FUNDING CRITERIA.

                  a. ESTABLISHMENT OF PARTICIPATION.  Upon execution of the Loan
Documents,  Seller  shall  deliver  to  Purchaser  a  Participation  Certificate
executed by Seller evidencing Purchaser's  contribution to the Loan, in the form
attached hereto as Exhibit "C" and hereby made a part hereof.

                  b. DEFAULT BY PURCHASER.  Any failure by Purchaser to make any
required advance when requested by Seller,  shall constitute a default hereunder
as of the day on which the payment was to be made by Purchaser.

         4. ALLOCATION OF PAYMENTS.  Distributions  of principal and interest to
Purchaser or to the Escrow  Account on behalf of  Purchaser  with respect to its
Participation Interest shall be made and payable only out of Payments.  Payments
shall be applied by Seller to the indebtedness owing by Borrower and distributed
to the Participants in the following order: (i) to all  Extraordinary  Expenses,
as hereinafter  defined,  to the extent thereof;  (ii) to liquidated damages and
late fees or charges  (other than  interest  and loan fees) owing under the Loan
Documents,  to the  extent  thereof;  (iii) to loan  fees  owing  under the Loan
Documents,  to the  extent  thereof;  (iv) to  accrued  interest,  to the extent
thereof;  and (v) to  unpaid  principal  of the  Loan.  Such  Payments  shall be
allocated among the Participants on the basis of Sections 5 and 13 hereof.

         5.       PAYMENTS TO PARTICIPANTS.

                  a.       ALLOCATIONS.  Subject to Sections 5(b), 5(c) and 13 
hereof,  each Participant  shall be entitled to share in the following payments 
to the extent and in the manner hereinafter set forth:

                                       2
<PAGE>


                           (i)  Extraordinary  Expenses, to the extent  advanced
by the  Participants, shall be reimbursed to the Participants on the basis which
the amount of Extraordinary Expenses advanced by each  Participant  bears to the
total  Extraordinary  Expenses  advanced  by all Participants.

                           (ii) All liquidated damages, late fees or charges and
other ancillary income (other than as provided
herein) shall be paid solely to Seller;

                           (iii) All loan,  extension,  prepayment  charges  and
reconveyance fees received from Borrower shall be
distributed to the Participants in accordance with their respective Percentage 
Interests;

                           (iv) All interest  payments  received from  Borrower,
excluding interest paid at the "Default Interest
Rate," as defined in the Note, shall be paid first to each  Participant,  or the
Escrow  Account  at  Seller's  election,  on the  basis  of  such  Participant's
respective  Percentage Interest,  to the extent the interest accrued at the rate
set forth in the Note on amounts advanced by such Participant from the date that
such amounts  were  disbursed to  Borrower;  and interest  payments  received by
Seller  from  Borrower  at the  Default  Interest  Rate  shall  be  paid  to the
Participants,  or the Escrow Account at Seller's election, on the basis of their
Percentage Interests, net of a 25 basis point servicing override to be allocated
to  Seller  and paid to  Seller  after  the  Participants  have  received  their
respective allocations of Default Interest Rate interest payment due and payable
under  the  Note  in  accordance  with  the  foregoing   Default  Interest  Rate
distribution; and

                           (v)  All  Payments  in  respect  of  and  applied  to
principal of the Loan received by Seller from Borrower
shall be paid to the Escrow Account on behalf of each  Participant in accordance
with their respective Percentage Interests.

                  b.  RIGHTS  TO FUNDS IN THE  EVENT OF  DEFAULT  BY  PURCHASER.
Notwithstanding the provisions of Section 5(a) hereof,  following any default by
Purchaser and in the event Payments are  insufficient  to pay the  Participant's
their respective  Percentage Interests under both Sections 5(a)(iv) and 5(a)(v),
each  Participant,  or the Escrow Account on behalf of each  Participant,  shall
receive its prorata share,  and only to the extent Seller  accepts,  in its sole
discretion, partial Payments.

                  c.  EFFECTIVE  DATE;  RETURNED  FUNDS.  For  purposes  of  the
calculations  of  amounts  due  to or  from  Purchaser,  Payments  allocated  to
principal and interest of the Loan shall be apportioned between the Participants
as of the time such Payments are received by Seller.  If any Payment received by
Seller and  distributed  or credited to Purchaser is later returned or repaid by
Seller to Borrower or its representative or successor in interest because of the
legal  obligation of Seller to do so,  Purchaser  shall,  upon notice by Seller,
immediately pay to Seller Purchaser's pro rata share of such Payment so returned
or repaid.  All funds held in the Escrow  Account shall be distributed in a time
and manner as reasonably  determined by Seller, but in no event will Payments in
respect of interest or principal payments be held in the Escrow Account for more
than sixty (60) days after the  Termination  Date.  All  interest  or  dividends
earned on the Escrow  Account  shall be  distributed  sixty (60) days after each
quarterly Payment under the Loan by Seller to Purchaser in accordance with their
respective Percentage Interest.

                  d. FORM OF PAYMENTS TO PURCHASER. Amounts payable to Purchaser
hereunder  shall be made by Seller to the  account  of  Purchaser.  Payments  or
credits in accordance  with Sections  5(a),  5(b) and 13 hereof shall be made by
check,  and, made on or before the 60th calendar day after Seller  receives such
amounts.

         6. ACCESS TO INFORMATION;  INDEPENDENT INVESTIGATION. Seller shall make
its files  relating to Borrower  available  for review by  Purchaser.  Purchaser
acknowledges that prior to its execution hereof it will have independently,  and
without  reliance  upon any  representations  of  Seller,  and  based on (i) the
financial  information  referred  to or set  forth in the Loan  Documents,  (ii)
various  information  provided  to  Purchaser  by  Borrower,   (iii)  its  prior

of any Loan  Document,  or of any other  matter  which  materially  affects  the
interest of Purchaser in the Loan.

         7. DOCUMENTS AND OTHER AGREEMENTS REGARDING ADMINISTRATION OF THE LOAN.
To facilitate  Seller's  administration  and  enforcement of the Loan on its own
behalf,  and as agent and as applicable,  trustee for  Purchaser,  and to induce
Seller to enter into this Agreement,  Purchaser  acknowledges and agrees that it
is in Purchaser's best interest that (i) Seller hold for itself,  and as trustee
for Purchaser, all executed original copies of the Loan Documents, at its office
at 1301 Capital of Texas Highway,  Suite C-300,  Austin,  Texas 78746;  and (ii)
Seller shall not be required to segregate from its own funds Payments  allocable
to Purchaser hereunder.  Upon written notice from Purchaser,  Seller will permit
Purchaser's agents, at any reasonable time during business hours, to examine the
originals  and/or copies of the Loan Documents which are in Seller's  possession
and  Seller's  books  and  records  relating  to the  Loan;  Seller  will,  upon
Purchaser's request, and at Purchaser's expense,  furnish to Purchaser copies of
such  documents  and  agreements  relating to the Loan as Seller may have in its
possession;  and Seller will use its best efforts,  at no expense to Seller,  to
obtain such other  documents  and  information  from or  concerning  Borrower as
Purchaser may reasonably request.

         8.  SELLER'S  REPRESENTATIONS,  DUTY  OF  CARE  AND  RESPONSIBILITY  TO
PURCHASER.

                  a.  LIMITED  WARRANTIES  AND  REPRESENTATIONS.  Seller  hereby
represents and warrants to Purchaser  that, at the time of closing the Loan, (i)
to the best of Seller's knowledge,  information and belief, no condition or fact
exists which would permit Seller to accelerate the Loan under the Loan Documents
and (ii) the Loan  conforms  in all  respects  to the  requirements  of the Loan
Documents.  Notwithstanding  the  foregoing,  to the extent of its  Contribution
Interest,  each  party  accepts  the  full  risk of  non-payment  of the Loan by
Borrower.  Seller shall not be responsible  for the performance or observance by
Borrower or any Obligor of any of the terms, covenants or conditions of the Loan
Documents  or for  the  inspection  or  policing  of the  Collateral.  Purchaser
specifically  acknowledges that Seller has made no warranty or representation to
Purchaser with respect to the  collectibility of the Loan or with respect to the
solvency,  financial  condition or future financial condition of Borrower or any
Obligor or the genuineness, existence or value of the Collateral.

                  b. DUTY OF CARE.  Seller shall manage and service the Loan and
Escrow Account in accordance with prudent practices,  modified from time to time
as it deems appropriate under the circumstances on its behalf and as independent
contractor  and trustee on behalf of  Purchaser,  and,  except as expressly  set
forth in Section 10 hereof,  Seller  shall be entitled to take all actions  with
respect to the Loan as if there were no other  Participant and as if Seller were
solely  involved in making the Loan.  Seller may act upon any  notice,  consent,
certificate,  cable,  telex or other instrument or writing believed by Seller to
be genuine, and Seller may consult with legal counsel,  independent accountants,
appraisers  and other experts  selected by Seller,  and provided that Seller has
not breached any duty of care as set forth in this  Section  8(b),  Seller shall
not be liable  for any  action  taken or  omitted  to be taken in good  faith by
Seller in accordance with the advice of such counsel, accountants, appraisers or
experts.  Seller shall not be liable to Purchaser under any circumstances except
for actual losses, if any, suffered by Purchaser hereunder which are proximately
caused either by Seller's  negligence,  gross negligence,  willful misconduct or
bad faith or by Seller's violation of the provisions of Section 10 hereof.

         9. WAIVERS AND RELEASE OF RIGHTS UNDER LOAN  DOCUMENTS.  Subject to the
affirmative  obligations imposed on Seller in Section 10 hereof, Seller reserves
the  right,  in its  sole  discretion,  at any  time or  times  hereafter,  upon
reasonable prior notice to Purchaser,  (i) to release any of the Collateral in a
manner which would not  materially  and adversely  impair the value of the Loan,
(ii) to modify,  waive or release  any of the terms of the Loan  Documents,  but
only if such  modification,  waiver or release does not materially and adversely
increase  risks  relating  to the  Loan,  (iii)  to  exercise  or  refrain  from
exercising  any powers or rights  which  Seller may have as a matter of law,  or
under, or in respect of the Loan Documents,  including,  without limitation, the
right to enforce the obligations of Borrower or any Obligor, and (v) to take any
other action  allowed  under the Loan  Documents or  applicable  law;  provided,
however,  that Seller shall not have the power or authority  hereunder,  without
the prior written  consent of Purchaser,  to waive any rights against or release
the Obligors. Seller shall not settle any judicial proceeding between it and any
Borrower without  obtaining the prior consent of Purchaser,  which consent shall
not be unreasonably withheld or delayed.

         10.  RESTRICTIONS  ON CHANGES IN FUNDAMENTAL  TERMS OF LOAN  DOCUMENTS.
Unless previously accomplished,  Seller shall at closing on the Loan execute and
deliver and cause  Borrower and each  Obligor to execute and deliver  those Loan
Documents required to be filed,  recorded or otherwise  perfected in such manner
as shall be  necessary  and  appropriate  to fully  secure the real and personal
property  securing the Loan, the rights,  privileges,  powers and benefits which
such Loan  Documents  are  intended  to confer  upon  Seller and  Purchaser.  In
addition,  Seller shall not,  without the written  consent of  Purchaser,  which
consent shall not be unreasonably withheld or delayed, take any of the following
actions:  (i) waive any  default by Borrower  involving  the payment of money to
Seller pursuant to the Loan Documents; (ii) extend the time of payment of any of
Borrower's  obligations with respect to the Loan for more than 60 days after any
due date;  (iii) agree to any change in the rate of interest payable by Borrower
with respect to the Loan (except for reductions  which are  contemplated  by the
Loan Documents);  (iv) release any liens or security  interests which secure the
Loan and relate to equipment,  fixtures or real estate if such release will have
a materially  adverse impact on the  Collateral;  or (v) terminate any financing
statements filed with respect to any of the Collateral.

         11. EXPENSES. Except as set forth herein, all normal costs and expenses
of monitoring and  collecting the Loan shall be borne by Seller.  Upon demand by
Seller,  Purchaser  shall  pay  its  share  of all  Extraordinary  Expenses,  as
hereinafter defined, incurred by Seller in connection with the Loan based on its
Percentage Interest. The term "Extraordinary Expenses" means all costs, expenses
(including,  without  limitation,  attorneys' fees and legal  expenses),  taxes,
costs and  expenses  of  appeals,  and  out-of-pocket  advances  (not  including
ordinary   overhead  expenses  or  salary  expenses  for  Seller's  clerical  or
supervisory  personnel)  which  are  incurred  by  Seller  at any  time or times
hereafter,  in connection  with (i) the  collection or  enforcement of the Loan;
(ii) the acquisition and preservation of the Collateral; (iii) the collection or
enforcement  of Borrower's  liabilities  to Seller,  or the  liabilities  of any
Obligor liable with respect to the Loan; (iv) the operation,  sale,  disposition
or other  realization  upon or the  recovery  of  possession  of the  Collateral
(including  the  collection  of  loss  proceeds  for  destruction   thereof  and
collection  of  awards  for  the  condemnation  thereof);  (v)  the  filing  and
prosecution of a complaint with respect to any of the above matters; or (vi) the
defense of any claim, actual or threatened by Borrower, a receiver or trustee in
bankruptcy for Borrower,  any Obligor or third party,  for, or on account of, or
with respect to the Loan, or the Loan Documents,  whether to recover damages for
business interference, for liabilities for debts of Borrower, including, but not
limited  to,  taxes,  for  alleged  preferences  or  fraudulent  conveyances  or
transfers  received or alleged to have been  received  from Borrower or any such
Obligor as a result of the Loan or in connection  with any Payments,  otherwise,
and shall include the amount of any recovery  from Seller in such  litigation or
proceeding, whether by settlement or pursuant to a judgment (except for any such
recovery  resulting  from the gross  negligence or willful  misconduct of Seller
about which Purchaser had no actual  knowledge or, if known by Purchaser,  about
which Purchaser objected by giving written notice to Seller).

                                       5
<PAGE>

         12. SELLER'S BOOKS AND RECORDS CORRECT.  Seller's books and records and
all  entries  thereon,  and  statement  received by  Purchaser  from Seller with
respect to the Loan,  will at all times (i) evidence both  Purchaser's  interest
and Seller's interest in the Loan; and, (ii) identify the same as such.

         13.      DEFAULT BY BORROWER.

                  a. In the event  default  occurs in the  payment  to Seller of
principal or interest on the Loan, Seller at its option,  but without obligation
to do so, may re-purchase any or all Purchasers' interests in the Loan.

                  b. In the event  Seller is unable to collect any sums when due
on the Loan,  after  exercising  reasonable  efforts to do so, Seller shall give
notice thereof to Purchaser, and, Seller may, if it determines it is in the best
interest of the Participants,  proceed to foreclose upon the Collateral securing
the Loan by  appropriate  proceedings,  or sale in lieu of  foreclosure.  Seller
shall in no way be required to take title to the  Collateral in its own name. If
Seller  determines  necessary,  Seller  may  create  a  separate  entity  as  an
Extraordinary Expense to take title to the Collateral.

                  c. If Seller or another  designated entity shall acquire title
to any of the Property or Collateral  covered by the Loan Documents after, or in
lieu of, foreclosure, all monies received or collected by it (including, but not
limited to, proceeds of title insurance claims) from the operation of or sale of
such property shall be applied in the following order of priority:

                           (i)   First, to the  reimbursement of  Extraordinary 
Expenses to the extent advanced by the Participants on the basis of their 
respective Percentage Interests;

                           (ii) Second, to the payment of any reconveyance fees,
prepayment penalties on the basis set forth in
clause (iii) of Section 5(a) hereof;

                           (iii) Third, to the payment of the entire amount then
due and payable under the Loan Documents for
accrued  interest in accordance with the terms thereof,  on the basis and in the
manner required by clause (iv) of Section 5(a) hereof (subject to the provisions
of Section 5(b) hereof);

                           (iv)  Fourth,  to  the  payment  of  the  outstanding
principal balance of the Loan in the manner required by
clause (v) of Section 5(a) hereof (subject to the provisions of Section 5(b) 
hereof);

                           (v) Fifth,  to the  payment of all accrued but unpaid
liquidated damages and late fees or charges (other
than interest and loan fees) which shall be paid solely to Seller; and

                           (vi) Sixth,  any surplus  shall be paid to Seller and
Purchaser in accordance with their respective
Percentage  Interests  provided that no Participant  which is then in default of
its  obligations  hereunder  shall in any event  receive  more  than the  unpaid
principal balance it has advanced in respect of the Loan.

                  d. In the event any or all of the Collateral encumbered by the
Loan Documents,  including the Property, are acquired by foreclosure, or by deed
in lieu of  foreclosure,  at a time  when  both  Seller  and  Purchaser  have an
interest in the Loan,  they shall have an undivided  interest in such Collateral
equal to the amount of their then respective  Percentage Interests as tenants in
common.

                                       6
<PAGE>

                  e.  In  the  event  Seller  shall  purchase  the  interest  of
Purchaser  pursuant to the  provisions  of this Section 13, the  purchase  price
shall be equal to the sum of: (i) all accrued but unpaid  interest in respect of
principal advanced by the selling party to which such party is entitled and such
other  amounts  accrued  but unpaid to the selling  party  pursuant to Section 5
hereof  through the date of such purchase,  and, (ii) all principal  advanced by
the  selling  party  and  subtracting   from  the  foregoing  sum   unreimbursed
Extraordinary Expenses advanced by the purchasing party.

         14.  SHARING OF SETOFFS AND  COLLATERAL.  Neither  Seller nor Purchaser
shall  set-off  against the amount of its  Percentage  Interest or other  claims
against Borrower, any of Borrower's accounts or funds now or hereafter received.
If Purchaser  shall receive  possession of any of the  Collateral for any reason
whatsoever,  such  Collateral  shall be held by Purchaser as Seller's  agent and
shall,  on demand,  be delivered to Seller.  Any  security  interest  granted by
Borrower to  Purchaser,  or Seller at any time or times  hereafter in all or any
part of the Collateral  described in the Loan Documents  shall be subordinate in
all respects to the interest of Purchaser and Seller  created by this  Agreement
or the Loan  Documents,  regardless of the actual date or order of filing of any
financing  statements or other means of perfection  under applicable law, or the
date of any loan or advance by Seller under the Loan Documents, and if Seller or
Purchaser  shall at any time hereafter hold any lien or security  interest other
than the  Collateral,  then  neither  shall not  commence  or take any action to
enforce that lien or security interest without giving the other thirty (30) days
prior written  notice.  Seller and Purchaser  each hereby  appoints the other as
their  agent for the  purpose of  perfecting  a security  interest in any of the
Collateral  which  may at any  time  come  into  the  possession  of  Seller  or
Purchaser.

         15.   PURCHASER'S   COMPLIANCE   WITH  LAW;  RESALE  OR  ASSIGNMENT  OF
PARTICIPATION; SALE OF ADDITIONAL PARTICIPATIONS.  Purchaser hereby warrants and
represents  to  Seller  that (i)  Purchaser's  execution  and  delivery  of this
Agreement and purchase of the  Participation  does not constitute a violation by
Purchaser of any agreement,  law,  statute,  decree or decisions  (including any
legal  lending  limits)  which is binding on  Purchaser;  and (ii)  Purchaser is
acquiring  the  Participation  for its own  account  and will not sell,  pledge,
encumber or assign its Participation, or any part thereof, to any person without
Seller's  prior written  consent.  Purchaser  may,  without  further  consent of
Seller,  and without releasing  Purchaser from liability  hereunder,  assign its
Participation  to a parent  or a  wholly  owned  subsidiary  of  Purchaser.  Any
prohibited  transfer  of an  interest  in the  Participation  shall  be  void if
attempted without Seller's written consent.  Purchaser may at any time, and from
time  to  time,   enter  into  one  or  more  agreements  with  other  financial
institutions to reparticipate its Participation; provided, however, that (i) any
such  reparticipation  shall not be deemed to be an  assignment  or  transfer of
Purchaser's Participation to such financial institution, (ii) any such financial
institution shall not be and shall not be deemed to be a party hereto or a third
party  beneficiary  hereof and Seller  shall have no duty or  liability  to such
financial institution whatsoever,  (iii) neither Seller's nor Purchaser's duties
hereunder may be assigned or transferred  hereunder,  (iv) such  reparticipation
shall not in any manner whatsoever relieve Purchaser from any of its obligations
or liabilities hereunder,  (v) such reparticipation shall not involved more than
one financial  institution,  which shall have previously engaged in the purchase
or  sale  of  participations  and  to all  of  which  full,  true  and  complete
information  concerning the Loan and Borrower shall have been provided, and (vi)
Purchaser  and each of its  participants  shall each have equal  shares with one
another.  Seller  may  participate,  reparticipate,  sell,  pledge or assign its
interest  in  the  Loan  or  its  Participation  to  any  other  person  without
Purchaser's consent. A Participation shall not be, and shall not be construed to
be, a "security" under any federal or state securities law.

Loan to  fund  potential  acquisitions  and  investments,  to  repurchase  up to
$1,000,000  market value of its stock, for general  corporate  purposes,  and to
guarantee  a loan from  Lender to  William  A.  Searles,  not to exceed  $85,000
outstanding  principal amount.  Borrower shall not use proceeds of any Borrowing
(i) to  purchase or carry any  "margin  securities"  (as such term is defined in
Regulation U of the Board of Governors of the Federal Reserve System),  (ii) for
any  unlawful  purpose,  or (iii) for the purpose of making any  hostile  tender
offer to acquire shares of stock or other equity interests in another Person.

         2.02.  MANNER OF BORROWING . Borrower  shall give Lender prior  written
notice on or before  10:00 a.m.  (Austin,  Texas time) on any day a Borrowing is
requested  (a "Notice of  Borrowing")  of each  requested  Borrowing in the form
attached as Exhibit C and shall specify the aggregate  amount and requested date
of such  Borrowing.  Each  Borrowing  shall be in an amount of $100,000.00 or an
integral  multiple  thereof.  Not later  than 2:00 p.m.  on the date  specified,
subject  to the  terms and  conditions  of this  Agreement,  Lender  shall  make

requested Borrowing in immediately available funds.

         2.03. FEES . In connection  with Lender's  agreement to enter into this
Agreement and fund the Loan  hereunder,  Borrower has committed to pay to Lender
an  up-front  commitment  fee in the  amount of $37,500  which  would be due and
payable upon the execution of this  Agreement.  In addition,  from and after the

equal to the following,  determined for the calendar  quarter (or portion of the
calendar  quarters  commencing  on the date of this  Agreement  or ending on the
Termination Date) preceding and including the date it is due: the product of (i)
1/4 of 1% per annum,  times (ii) the amount by which the average daily Revolving
Credit  Commitment  exceeds the sum of the average daily Principal  Debt,  times
(iii) a fraction with the number of days in the applicable quarter or portion of
it as the numerator and 360, as the denominator.  Borrower acknowledges that the
commitment fee payable  hereunder is a bona fide  commitment fee and is intended
as reasonable  compensation  to Lender for committing to make funds available to
Borrower as described herein and for no other purposes.

         2.04.    NOTES AND NOTE PAYMENTS .

                  (a) NOTE.  The  Borrowings  made under  Section 2.01 by Lender

<PAGE>

                           (2)  OPTIONAL  PREPAYMENTS.  Borrower  shall have the
         right,  from time to time upon three (3) Business  Days' written notice
         to Lender, and without penalty, to prepay the Note, in whole or in part
         upon the  payment of  accrued  interest  on the  amount  prepaid to and
         including the date of payment.

                           (3) MANNER AND APPLICATION OF PAYMENTS.  All payments
         and prepayments by Borrower on account of principal, interest, and fees
         hereunder  shall  be made in  immediately  available  funds.  All  such
         payments  shall be made to Lender at its office in Austin,  Texas,  not
         later than 12:00 noon,  Austin,  Texas time,  on the date due and funds
         received  after  that hour  shall be deemed  to have been  received  by
         Lender on the next following  Business Day. If any payment is scheduled
         to become due and  payable on a day which is not a Business  Day,  such
         payment  shall  instead  become  due  and  payable  on the  immediately
         following  Business Day and interest on the  principal  portion of such
         payment  shall be  payable  at the then  applicable  rate  during  such
         extension.  All  payments  made on the Note shall be  credited,  to the
         extent of the  amount  thereof,  in the  following  manner:  (i) first,
         against the amount of interest accrued and unpaid on the Note as of the
         date of such  payment;  and (ii) second,  against all principal due and
         owing on the Note as of the date of such payment.

         2.05.    INTEREST .

         (a) INTEREST RATE. Subject to Section 2.05(b),  the unpaid principal of
each Borrowing shall bear interest from the date of advance until paid at a rate
per annum that from day-to-day  equals the lesser of (a) the Base Rate in effect
from day-to-day minus 1/4 of 1% (the "Contract Rate"), or (b) the Maximum Rate.

         (b)  DEFAULT  RATE.  All  past  due  principal  of,  and to the  extent
permitted by applicable  law,  interest on, the Note shall bear  interest  until
paid at the lesser of (i) the Base Rate from  time-to-time  in effect plus three
percent (3%), or (ii) the Maximum Rate.

         (c)  COMPUTATION OF INTEREST RATES.  Subject to applicable  usury laws,
interest shall be computed at a daily rate equal to 1/360 of the applicable rate
of interest per annum for all  Borrowings,  unless the Maximum Rate or Base Rate
shall be in effect,  in which case  interest  shall be  computed at a daily rate
equal to 1/365 or 1/366, as appropriate,  of the applicable rate of interest per
annum.

         (d) RECAPTURE RATE. If, on any interest  payment date,  Lender does not
receive  interest on the Note computed (as if no Maximum Rate  limitations  were
applicable)  at the  Contract  Rate  pursuant  to Section  2.05(a)  because  the
Contract  Rate exceeds or has exceeded the Maximum Rate,  then  Borrower  shall,
upon the  written  demand of Lender,  pay to Lender,  in  addition  to  interest
otherwise  required  hereunder,  on each interest payment date  thereafter,  the
Excess  Interest  Amount  (hereinafter  defined)  calculated  as of  such  later
interest  payment date;  provided,  however,  that in no event shall Borrower be
required to pay,  for any  appropriate  computation  period,  interest at a rate
exceeding  the Maximum  Rate  effective  during such  period.  The term  "Excess
Interest  Amount" means,  on any date, the amount by which (a) the amount of all
interest  that would have accrued  before that date on the principal of the Note
(had  the  applicable  Contract  Rate  at all  times  been  in  effect,  without
limitation by the Maximum  Rate)  exceeds (b) the  aggregate  amount of interest
actually paid to Lender on the Note on or before that date.

<PAGE>

         2.06.  TAXES . Any and all payments by Borrower  hereunder or under the
Note  shall be made  free and  clear of and  without  deduction  for any and all
present or future taxes, levies, imposts,  deductions,  charges or withholdings,
and all liabilities with respect thereto  (hereinafter  referred to as "Taxes"),
excluding  taxes  imposed on Lender's  income,  and  franchise  taxes imposed on
Lender, by the jurisdiction under the laws of which Lender is organized or is or
should be qualified  to do business or any  political  subdivision  thereof and,
taxes imposed on Lender's  income,  and franchise taxes imposed on Lender by the
jurisdiction of Lender's lending office or any political subdivision thereof. If
Borrower  shall be required by law to deduct any Taxes from or in respect of any
sum payable hereunder or under the Note to Lender,  (i) the sum payable shall be
increased  as may be  necessary  so that after  making all  required  deductions
(including  deductions  applicable to additional sums payable under this Section
2.06) Lender  receives an amount equal to the sum it would have  received had no
such  deductions  been made,  (ii) Borrower shall make such deductions and (iii)
Borrower shall pay the full amount deducted to the relevant  taxation  authority
or other authority in accordance  with  applicable law.  Borrower will indemnify
Lender for the full amount of Taxes (including,  without  limitation,  any Taxes
imposed by any  jurisdiction on amounts payable under this Section 2.06) paid by
Lender or any liability  (including penalties and interest) arising therefrom or
with  respect  thereto,  whether  or not such Taxes  were  correctly  or legally
asserted.  This  indemnification  shall be payable  upon Lender  making  written
demand therefor.

         2.07.  CAPITAL ADEQUACY . If, after the date hereof,  Lender shall have
reasonably  determined  that either (i) the adoption  (after the date hereof) of
any applicable law, rule, regulation or guideline regarding capital adequacy, or
any  change  therein,  or any  change in the  interpretation  or  administration
thereof by any Governmental Authority, central bank or comparable agency charged
with the interpretation or administration  thereof, or (ii) compliance by Lender
(or any lending  office of Lender) with any request or directive  (issued  after
the date hereof)  regarding capital adequacy (whether or not having the force of
law) of any such  authority,  central  bank or  comparable  agency,  and  having
general  application to lenders such as Lender,  has or would have the effect of
reducing  the rate of return on  Lender's  capital  as a  consequence  of its or
Borrower's  obligations  hereunder to a level below that which Lender could have
achieved but for such  adoption,  change or compliance  by an amount  reasonably
deemed by Lender to be  material,  then from time to time,  within five (5) days
after demand by Lender,  Borrower shall pay to Lender such additional  amount as
will adequately  compensate  Lender for such  reduction,  provided that Borrower
will not be  required  to pay any more  than  similarly  situated  customers  of
Lender.  Lender  will  notify  Borrower  of any  event of  which  it has  actual
knowledge,  occurring  after the date  thereof,  which  will  entitle  Lender to
compensation  pursuant to this Section 2.07. No failure by Lender to immediately
demand payment of any additional  amounts payable  hereunder shall  constitute a
waiver of Lender's  right to demand  payment of such  amounts at any  subsequent
time.


                                    SECTION 3

deemed to, give Lender the right
or power to exercise control over the management and affairs of Borrower.

                                 MISCELLANEOUS

         8.01.  ACCOUNTING  REPORTS  . All  financial  reports  or  projections,
furnished by any Person to Lender  pursuant to this Agreement  shall be prepared
in such  form and such  detail  as shall be  satisfactory  to  Lender,  shall be
prepared on the same basis as those prepared by such Person in prior years.

         8.02. WAIVER . No failure to exercise,  and no delay in exercising,  on
the part of Lender,  any right hereunder shall operate as a waiver thereof,  nor
shall any  single or  partial  exercise  thereof  preclude  any other or further
exercise  thereof or the exercise of any other right. The rights of Lender under
the Loan Documents  shall be in addition to all other rights provided by law. No
modification  or waiver of any  provision of any Loan  Document,  nor consent to
departure therefrom, shall be effective unless in writing and no such consent or
waiver shall extend beyond the particular case and purpose  involved.  No notice
or demand given in any case shall constitute a waiver of the right to take other
action in the same, similar or other instances without such notice or demand.

         8.03. NOTICES . Any communications required or permitted to be given by
any of the Loan  Documents  must be (i) in writing and  personally  delivered or
mailed by  prepaid  certified  or  registered  mail,  or (ii) made by  facsimile
transmission  delivered  or  transmitted,  to the party to whom  such  notice of
communication is directed,  to the address of such party shown opposite its name
on the signature pages hereof.  Any such  communication  shall be deemed to have
been  given  (whether  actually  received  or not)  on the day it is  personally
delivered or, if  transmitted  by facsimile  transmission,  on the day that such
communication is transmitted as aforesaid  subject to telephone  confirmation of
receipt; provided,  however, that any notice received by Lender after 10:00 a.m.
Austin,  Texas time on any day from  Borrower  pursuant  to  Section  2.02 (with
respect  to a Notice of  Borrowing)  shall be deemed  for the  purposes  of such
Section to have been given by Borrower on the next succeeding day, or if mailed,
on the  third day after it is marked  as  aforesaid.  Any party may  change  its
address for purposes of this  Agreement  by giving  notice of such change to the
other parties pursuant to this Section 8.03.

         8.04.  GOVERNING  LAW . This  Agreement  has  been  prepared,  is being
executed  and  delivered,  and is intended to be performed in the State of Texas
and the  substantive  laws of such state and the applicable  federal laws of the
United States of America shall govern the  validity,  construction,  enforcement
and interpretation of this Agreement and all of the other Loan Documents.

         8.05. INVALID PROVISIONS . Any provision of any Loan Document held by a
court of competent  jurisdiction to be illegal,  invalid or unenforceable  shall
not invalidate the remaining provisions of such Loan Document which shall remain
in full force and effect the effect  thereof  shall be confined to the provision
held invalid or illegal.

         8.06. MAXIMUM INTEREST RATE . Regardless of any provision  contained in
any of the Loan Documents, Lender shall never be entitled to receive, collect or
apply as interest on the Note any amount in excess of interest calculated at the
Maximum  Rate,  and,  in the event that any Lender  ever  receives,  collects or
applies as  interest  any such  excess,  the  amount  which  would be  excessive
interest  shall be deemed to be a partial  prepayment  of principal  and treated
hereunder as such;  and, if the  principal  amount of the  Obligation is paid in
full, any remaining  excess shall forthwith be paid to Borrower.  In determining
whether or not the  interest  paid or  payable  under any  specific  contingency


                                       22
<PAGE>

exceeds interest  calculated at the Maximum Rate,  Borrower and Lender shall, to
the  maximum  extent  permitted  under  applicable  law,  (i)  characterize  any
nonprincipal payment as an expense, fee or premium rather than as interest; (ii)
exclude  voluntary  prepayments  and the effects  thereof;  and (iii)  amortize,
prorate,  allocate  and spread,  in equal  parts,  the total  amount of interest
throughout the entire  contemplated term of the Note; provided that, if the Note
is paid and  performed  in full prior to the end of the full  contemplated  term
thereof, and if the interest received for the actual period of existence thereof
exceeds interest calculated at the Maximum Rate, Lender shall refund to Borrower
the  amount of such  excess or credit  the  amount of such  excess  against  the
principal amount of the Note and, in such event,  Lender shall not be subject to
any  penalties  provided  by any laws for  contracting  for,  charging,  taking,
reserving or receiving interest in excess of interest  calculated at the Maximum
Rate.

         8.07.  NONLIABILITY OF LENDER . The  relationship  between Borrower and
Lender is, and shall at all times remain, solely that of Borrower and Lender and
Lender has no fiduciary or other special relationship with Borrower.

         8.08. OFFSET . Borrower hereby grants to Lender the right of offset, to
secure repayment of the Obligation, upon any and all moneys, securities or other
property  of Borrower  and the  proceeds  therefrom,  now or  hereafter  held or
received  by or in transit to Lender or its  agents,  from or for the account of
Borrower, whether for safe keeping, custody, pledge, transmission, collection or
otherwise,  and also upon any and all deposits  (general or special) and credits
of  Borrower,  and any and all  claims of  Borrower  against  Lender at any time
existing.

         8.09. SUCCESSORS AND ASSIGNS . The Loan Documents shall be binding upon
and inure to the benefit of Borrower and Lender and their respective successors,
assigns and legal  representatives;  provided,  however,  that Borrower may not,
without the prior written consent of Lender,  assign any rights,  powers, duties
or obligations thereunder.

         8.10.  CHAPTER  346.  The  Borrower  and Lender  hereby  agree that the
provisions of Chapter 346 of the Finance Code of the State of Texas  (regulating
certain revolving credit loans and revolving  triparty accounts) shall not apply
to the Loan Documents.

         8.11. HEADINGS . Section headings are for convenience of reference only
and shall in no way affect the interpretation of this Agreement.

         8.12.  SURVIVAL . All  representations  and warranties made by Borrower
herein shall survive delivery of the Note and the making of the Loan.

         8.13.  PARTICIPATIONS  .  Lender  shall  have the  right to enter  into
participation  agreements  with other banks with respect to the Note,  and grant
participations  in Loan  Documents but such  participation  shall not affect the
rights and duties of such Lender hereunder  vis-a-vis  Borrower.  Each actual or
proposed  participant  shall be entitled to receive from Lender all  information
received  by Lender  regarding  the  creditworthiness  of  Borrower,  including,
without  limitation,  information  required  to be  disclosed  to a  participant
pursuant  to  Banking  Circular  181  (Rev.,  August  2,  1984),  issued  by the
Comptroller  of the  Currency  (whether  the actual or proposed  participant  is
subject to the circular or not).

         8.14.  NO THIRD  PARTY  BENEFICIARY  . The  parties  do not  intend the
benefits  of this  Agreement  to inure to any  third  party,  nor shall any Loan
Document or any course of conduct by any party  hereto be  construed  to make or
render Lender or any of its officers,  directors, agents or employees liable (i)
to any materialman, supplier, contractor, subcontractor,  purchaser or lessee of
any property owned by Borrower, or (ii) for debts or claims accruing to any such
Persons against Borrower.

         8.15.  Waiver  of  Jury  Trial . TO THE  FULLEST  EXTENT  PERMITTED  BY
APPLICABLE LAW, BORROWER HEREBY  IRREVOCABLY AND EXPRESSLY WAIVES ALL RIGHT TO A
TRIAL BY JURY IN ANY ACTION,  PROCEEDING,  OR  COUNTERCLAIM  (WHETHER BASED UPON

THE NEGOTIATION, ADMINISTRATION, OR ENFORCEMENT THEREOF.

excess of the maximum  rate of interest  permitted  to be charged by  applicable
law,  and, if Payee ever  receives,  collects  or applies as  interest  any such

reduce the unpaid principal  balance of this Note, and, if the principal balance
of this  Note is paid in full by that  application,  then any  remaining  excess

that the interest rate is uniform throughout that term.

         5. This Note has been  executed and  delivered  pursuant to a Revolving
Credit Loan Agreement (as modified,  amended, or supplemented from time to time,
the "Loan Agreement"),  dated the date hereof, executed by and between Maker and

entitled to the  benefits  provided in the Loan  Agreement.  Reference is hereby
made to the Loan  Agreement  for a statement of (i) the  obligation  of Payee to
advance funds hereunder, (ii) the prepayment rights and obligations of Maker and
(iii) the events on which the maturity of this Note may be accelerated.

         6. If the  principal of, or any  installment  of interest on, this Note
becomes due and payable on a day other than a Business  Day,  then the  maturity
thereof shall be extended to the next succeeding  Business Day. If this Note, or
any  installment  or payment  due  hereunder,  is not paid when due,  whether at
maturity or by acceleration, or if it is collected through a bankruptcy, probate
or other court, whether before or after maturity, then Maker shall pay all costs
of collection,  including,  but not limited to,

other act of any trustee or any holder hereof, whether before or after maturity.

thereof (if  applicable),  and all  repayments of the  principal  thereof may be
recorded  by Payee and,  before any  transfer  hereof,  endorsed by Payee on the
schedule attached hereto, or on a continuation of the schedule attached to and a
part hereof,  provided that the failure of Payee to record any endorsement shall
not affect the obligation of Maker hereunder or under the Loan Agreement.

performed  in the State of  Texas.  Except  to the  extent  that the laws of the

shall be deemed a power  coupled with an interest and shall not be terminable as
long as the Obligation is outstanding  and shall not terminate on the disability
or  incompetence  of Pledgor.  Without  limiting the ability to perform any acts
authorized  by the  foregoing,  Bank shall have the right and power to  receive,
endorse and  collect  all checks and other  orders for the payment of money made
payable to Pledgor but only to the extent that such checks or payments represent
any dividend,  interest payment or other distribution  payable in respect of the
Collateral  or any  part  thereof.  Bank  will  notify  Pledgor  after  Bank has
exercised the power,  and Bank shall deliver to Pledgor  copies of any documents
executed by Bank pursuant to the power.  Upon payment of the entire  Obligation,
the power  described in this  Section  shall be deemed to be  terminated.  
P. 
Q. OTHER PARTIES AND OTHER COLLATERAL. No renewal or  extensions of or any other
indulgence  with respect to the Obligation or any part thereof,  no modification
of the  document(s)  evidencing the Obligation,  no release of any security,  no
release  of any person  (including  any maker,  indorser,  guarantor  or surety)
liable on the  Obligation,  no delay in enforcement of payment,  and no delay or
omission  or lack of  diligence  or care in  exercising  any right or power with
respect to the Obligation or any security  therefor or guaranty thereof or under
this Agreement shall in any manner impair or affect the rights of Bank under any
law, hereunder, or under any other agreement pertaining to the Collateral.  Bank
need not file suit or assert a claim for  personal  judgment  against any person
for any part of the  Obligation  or seek to realize upon any other  security for
the Obligation,  before foreclosing or otherwise  realizing upon the Collateral.
Pledgor  waives any right that can be waived to the  benefit of or to require or
control  application of any other security or proceeds thereof,  and agrees that
Bank shall have no duty or obligation to Pledgor to apply to the  Obligation any
such other  security  or proceeds  thereof.  
R. 
S.  WAIVERS BY PLEDGOR.  Pledgor
waives  notice of the  creation,  advance,  increase,  existence,  extension  or
renewal  of, and of any  indulgence  with  respect  to, the  Obligation;  waives
presentment,  demand,  notice of  dishonor,  and protest;  waives  notice of the
amount  of the  Obligation  outstanding  at any time,  notice  of any  change in
financial condition of any person liable for the Obligation or any part thereof,
notice of any Event of Default, and all other notices respecting the Obligation;
and  agrees  that  maturity  of the  Obligation  and  any  part  thereof  may be
accelerated,  extended or renewed  one or more times by Bank in its  discretion,
without  notice to Pledgor.  Pledgor waives any right to require that any action
be brought  against  any other  person or to require  that  resort be had to any
other security or to any balance of any deposit account.  Pledgor further waives
any right of  subrogation  or to enforce  any right of action  against any other
pledgor  until the  Obligation  is paid in full.  
T. 
U. RULE 144 RIDER.  Pledgor
acknowledges that the Collateral is, or may be in the future, comprised in whole
or in part of control or  restricted  securities,  which shall be subject to the
additional terms and provisions  described on the Rule 144 Rider attached hereto
and made a part hereof for all purposes.

6. 


                                       5
<PAGE>

A.
MAINTENANCE  OF  COLLATERAL.  At all times  during  the term of this  Agreement,
Pledgor agrees to maintain as security for the Obligation,  Prime Pledged Shares
with an Adjusted  Collateral  Value (as determined  herein) in excess of 182% of
the unpaid principal balance of the Obligation (the "Maintenance  Margin").  The
Adjusted Collateral Value shall be determined by multiplying the number of Prime
Pledged Shares (including any Additional  Shares) by the per share price of such
Prime stock at the most recent  close of trading on a trading  exchange  for the
Prime  stock.  In the event  that  Prime  Pledged  Shares  are not  traded on an
exchange,  the Adjusted  Collateral  Value of the Prime Pledged  Shares shall be
determined  by obtaining  the quoted value of such Prime  Pledged  Shares from a
reputable  brokerage  firm selected by Bank. If no such quote is available,  the
value will be determined by Bank in its sole discretion.  
B. 
C. No Borrowing (as
defined in the Loan Agreement)  requested by Pledgor shall be made to Pledgor if
the sum of (i) the outstanding principal balance of the Obligation plus (ii) the
amount  of the  Borrowing  requested,  equals  or  exceeds  50% of the  Adjusted
Collateral Value (the "Original Advance Percentage").
D. 
E. BREACH OF COLLATERAL MAINTENANCE. Pledgor agrees that the failure to maintain
Collateral with an Adjusted Collateral Value as set forth above shall constitute
an Event of Default under this Agreement.  In such event, the Pledgor shall have
five Business Days (as defined in the Loan  Agreement)  from the date Pledgor is
notified by Bank (in writing or orally) of such noncompliance,  to either pledge
additional  shares of Prime stock  satisfactory to Bank, in its sole discretion,
or reduce the unpaid  principal  balance of the Obligation  such that, in either
case,  the  Adjusted  Collateral  Value  shall be not less than the  Maintenance
Margin.  In the event Pledgor  fails to comply with the terms hereof,  Bank may,
without any further notice of any kind, exercise any of the following rights and
remedies, at Bank's option: 
F.
         (a)      The rights and remedies set out in Section 8.B. of this 
                  Agreement, including without limitation the right to
                  accelerate the Obligation and liquidate the Collateral.

         (b)      Sell all or any part of the  Collateral and apply the proceeds
                  of such sale to the  Obligation to bring the  Obligation  back
                  into  compliance  (that is, to reduce the unpaid  principal of
                  the  Obligation   such  that  the  unpaid   principal  of  the
                  Obligation  is less than  Original  Advance  Percentage of the
                  Prime Pledged Shares.

If an Event of Default exists hereunder and the Collateral is declining in value
or  threatens to decline  speedily in value,  Bank shall have no  obligation  to
notify  Pledgor of the failure to maintain Prime Pledged Shares with an Adjusted
Collateral Value as set forth in subparagraph A above or to provide Pledgor with
an opportunity to cure such noncompliance,  and in such case Pledgor agrees that
Bank may  immediately  at Bank's sole  option (i) declare  amounts due under the
Obligation to be immediately  due and payable,  and/or (ii) sell all or any part
of the Collateral and apply the proceeds of such Collateral to the Obligation.

A. ADDITIONAL PLEDGE PROVISION.  Notwithstanding the provisions of 6A and 6B, in
the  event the per share  price of the Prime  Pledged  Shares on any day is less
than $8.25, than all shares of Prime owned by Pledgor (other than 500,000 shares
of common  stock of Prime which shall be  excluded)  (the "Prime  Stock")  shall
become Additional Collateral  hereunder,  and Pledgor shall,  immediately,  upon
demand of Bank,  execute and deliver a Pledge  Certificate  covering  such Prime
Stock shares to Bank,  together with the original stock  certificates  and blank
stock  powers.  
B. 
C. RELEASE OF PRIME  PLEDGED  SHARES.  
D. 
i. In the event the
price per share of the  Prime  Pledged  Shares  increases  so that the  Adjusted
Collateral  Value is in excess of 250% of the  Obligation,  then upon receipt of
Pledgor's  written 


                                       6
<PAGE>

request to Bank  requesting  release of certain Prime Pledged
Shares,  and  provided  no  Default  or Event of  Default  has  occurred  and is
continuing under the Loan Agreement,  Bank shall as soon as reasonably  possible
(but in any event no earlier than ten  Business  Days  following  receipt of the
request)  release  certain  Prime  Pledged  Shares,  so  long  as  the  Adjusted
Collateral  Value of the remaining Prime Pledged Shares is not less than 200% of
the Obligation. 
ii. 
iii. In the event Pledgor has pledged all of its Prime Stock
shares to Bank as required  pursuant to Section 6C above,  then if the per share
price  of the  Prime  Pledged  Shares  exceeds  $8.50  during  any  ninety  (90)
consecutive  days,  and Pledgor  delivers a written  request to Bank  requesting
release of certain Prime Pledged Shares, provided no Default or Event of Default
has occurred and is continuing under the Loan Agreement, then Bank shall as soon
as  reasonably  possible  (but in any event no earlier  than ten  Business  Days
following  receipt of the request) release certain Prime Pledged Shares, so long
as the Adjusted  Collateral  Value of the remaining  Prime Pledged Shares is not
less than 200% of the  Obligation.  
iv. 
v.  Nothing in this  Section  6D.  shall
relieve Pledgor of its continuing  obligations under Sections 6A, 6B and 6D. vi.
E. RELEASE OF OTHER  COLLATERAL.  
F. 
i. In the event that FPIC Insurance  Group,
Inc. ("FPIC") exercises its option to purchase additional shares of common stock
of APS Insurance Services, Inc., a Delaware corporation ("APS Insurance") as set
forth in the Stock Purchase and Stock Option Agreement  entered into as of April
6, 1997 and in the  Shareholders  Agreement  entered into on June 30, 1997 among
APS  Insurance,  Pledgor  and FPIC,  Bank shall  release  its lien and  security
interest in the  Collateral  consisting  of the pledged  shares of APS Insurance
upon  receipt by Bank of the  purchase  price  therefor. 
ii. 
iii. The Bank also
agrees that provided no Event of Default (hereinafter  defined) has occurred and
is  continuing,  shares  of  common  stock  of  APS  Practice  Management,  Inc.
("Practice  Management") will be released from the lien and security interest of
this  Agreement  upon not less than ten (10) Business Days written notice to the
Bank,  setting  forth  the  number of  shares  to be  released,  the name of the
purchaser to whom the shares are to be transferred and the reason therefor.  
iv.
2. RIGHTS AND POWERS OF BANK.  
3. 
A.  GENERAL.  Bank,  before or after  default,
without  liability to Pledgor may:  take  control of proceeds,  including  stock
received as dividends or by reason of stock  splits;  release the  Collateral in
its  possession to any Pledgor,  temporarily  or otherwise;  require  additional
Collateral;  reject as unsatisfactory  any property hereafter offered by Pledgor
as Collateral;  take control of funds generated by the Collateral,  such as cash
dividends,  interest  and  proceeds,  and use  same to  reduce  any  part of the
Obligation  and exercise all other rights which an owner of such  Collateral may
exercise,  except the right to vote or dispose of the Collateral before an Event
of Default;  and at any time transfer any of the Collateral or evidence  thereof
into its own name or that of its nominee.  Other than the exercise of reasonable
care to ensure the safe custody of the  Collateral  in Bank's  possession,  Bank
shall  have  no  obligation,  duty or  responsibility  for  the  Collateral  and
specifically,  without limiting the foregoing, shall have no obligation, duty or
responsibility to collect any amounts payable,  or exercise any right or option,
in respect of the  Collateral or to sell all or any portion of the Collateral to
avoid market  loss.  Bank shall not be liable for failure to collect any account
or  instruments,  or for any act or omission on the part of Bank,  its officers,
agents or  employees,  except for its or their own willful  misconduct  or gross
negligence.  The foregoing rights and powers of Bank will be in addition to, and
not a limitation upon, any rights and powers of Bank given by law,  elsewhere in
this Agreement, or otherwise. 


                                       7
<PAGE>

B.
C. CONVERTIBLE COLLATERAL. Bank may present for
conversion any  Collateral  which is  convertible  into any other  instrument or
investment  security or a combination thereof with cash, but Bank shall not have
any duty to present for conversion any Collateral  unless it shall have received
from Pledgor detailed  written  instructions to that effect at a time reasonably
far in advance of the final conversion date to make such conversion possible.
D.
E. VOTING  RIGHTS.  Subject to the  following  sentence,  the  Pledgor  shall be
entitled  to exercise  any and all voting  and/or  consensual  rights and powers
relating or pertaining to the Collateral or any part thereof for any purpose not
inconsistent with the terms of this Agreement. Upon (i) the occurrence after the
date hereof of an Event of Default and (ii) the giving of written notice by Bank
to Pledgor of its  intention to (A) foreclose  upon or otherwise  dispose of the
Collateral or (B) exercise its voting rights  pertaining to the Collateral,  all
rights of the Pledgor to exercise the voting and/or consensual rights and powers
which it is entitled to exercise  hereunder  shall cease, at the option of Bank,
and all such rights  shall  thereupon  become  vested in Bank who shall have the
sole and exclusive right and authority to exercise such voting and/or consensual
rights and powers.  
F. 
4. DEFAULT.  
5. 
A. EVENT OF DEFAULT.  An event of default
("Event of Default")  shall occur (a) if Pledgor or any other  obligor on all or
part of the Obligation shall fail to timely and properly pay or observe, keep or
perform any term,  covenant,  agreement or condition in this Agreement or in any
other  agreement  between Pledgor and Bank or between Bank and any other obligor
on the  Obligation,  including but not limited to any other note or  instrument,
loan agreement,  security agreement,  deed of trust, mortgage,  promissory note,
assignment or other agreement or instrument concerning the Obligation; or (b) an
Event of  Default  shall  occur  under  the Loan  Agreement  or any  other  Loan
Document.

A. RIGHTS AND REMEDIES.  If any Event of Default shall occur,  then, in each and
every such case, Bank may,  without (a)  presentment,  demand,  or protest,  (b)
notice of default,  dishonor,  demand,  non-payment,  or protest,  (c) notice of
intent  to  accelerate  all or  any  part  of  the  Obligation,  (d)  notice  of
acceleration  of all or any part of the  Obligation,  or (e) notice of any other
kind,  all of which  Pledgor  hereby  expressly  waives  (except  for any notice
required  under  this  Agreement,  any other Loan  Document  or which may not be
waived under applicable law), at any time thereafter exercise and/or enforce any
of the following rights and remedies, at Bank's option: 
B. 
i. ACCELERATION.  The
Obligation shall, at Bank's option,  become immediately due and payable, and the
obligation,  if any, of Bank to permit further  borrowings  under the Obligation
shall at Bank's option immediately cease and terminate. 
ii. 
iii. LIQUIDATION OF
COLLATERAL.  Sell,  or instruct any agent or broker to sell,  all or any part of
the  Collateral  in a public  or  private  sale,  direct  any agent or broker to
liquidate  all or any part of any account and  deliver all  proceeds  thereof to
Bank,  and apply all proceeds to the payment of any or all of the  Obligation in
such  order  and  manner  as Bank  shall,  in its  discretion,  choose.  Bank is
authorized, at any sale of the Collateral, if it deems it advisable, to restrict
the  prospective  bidders of Purchasers to those persons who will  represent and
agree that they are purchasing for their own account,  for  investment,  and not
with a view to  distribution  or sale of any of the  Collateral.  Pledgor agrees
that,  because of the Securities  Act of 1933, as amended,  or any other laws or
regulations,  and  for  other  reasons,  there  may be  legal  and/or  practical
restrictions or limitations affecting Bank in any attempts to dispose of certain
portions of the  Collateral and for the  enforcement of their rights.  For these
reasons,  Bank is hereby  authorized  by Pledgor,  but not  obligated,  upon the
occurrence and during the  continuation  of an Event of Default,  to sell all or
any part of the Collateral at private sale,  subject to investment  letter or in


                                       8
<PAGE>

any other manner which will not require the Collateral,  or any part thereof, to
be registered in accordance with the Securities Act of 1933, as amended,  or the
rules and regulations promulgated thereunder,  or any other laws or regulations,
at a reasonable  price at such private sale or other  distribution in the manner
mentioned above.  Pledgor understands that Bank may in its discretion approach a
limited number of potential  purchasers and that a sale under such circumstances
may yield a lower price for the Collateral,  or any part or party thereof,  than
would  otherwise be  obtainable  if such  collateral  were either  afforded to a
larger number or potential purchasers, or registered or sold in the open market.
Pledgor  agrees  that such  private  sale shall be deemed to have been made in a
commercially reasonable manner, and that Bank has no obligation to delay sale of
any Collateral to permit the issuer thereof to register it for public sale under
any  applicable  federal  or  state  securities  laws.  Bank is  authorized,  in
connection  with any such sale (i) to  restrict  the  prospective  bidders on or
purchasers  of  any of the  Collateral  to a  limited  number  of  sophisticated
investors who will  represent and agree that they are  purchasing  for their own
account for investment and not with a view to the distribution or sale of any of
such  Collateral  and (ii) to impose such other  limitations  or  conditions  in
connection  with any such sale as Bank  reasonably  deems  necessary in order to
comply with  applicable law.  Pledgor  covenants and agrees that he will execute
and deliver such documents and take such other action as Bank  reasonably  deems
necessary in order that any such sale may be made in compliance  with applicable
law.  Upon any such  sale,  Bank  shall  have the right to  deliver,  assign and
transfer to the purchaser  thereof the Collateral so sold. Each purchaser at any
such sale shall hold the Collateral so sold  absolutely,  free from any claim or
right of Pledgor of whatsoever kind, including any equity or right of redemption
of  Pledgor.  Pledgor,  to  the  extent  permitted  by  applicable  law,  hereby
specifically waives all rights of redemption,  stay or appraisal which he has or
may have under any law now  existing or hereafter  enacted.  
iv. 
v. In addition,
and  without  limiting  the  foregoing,  Pledgor  agrees  that Bank may,  in its
discretion,  advertise,  prepare  for,  and  conduct a  foreclosure  sale of the
Collateral pursuant to newspaper  advertisements or other public advertisements,
in accordance  with (and subject to conditions set forth in) no action  letters,
pronouncements  and requirements of the Securities and Exchange  Commission,  in
order to comply with the Securities  Act of 1933, as amended,  or any other laws
or regulations.  
vi. 
vii. UNIFORM COMMERCIAL CODE. All of the rights, powers and
remedies of a secured  creditor  under the Uniform  Commercial  Code  ("UCC") as
adopted in the jurisdiction to which Bank is subject under this Agreement. 
viii.
ix.  RIGHT OF SET OFF.  Without  notice or demand to Pledgor,  set off and apply
against any and all of the Obligation any and all deposits  (general or special,
time or demand,  provisional or final) and any other  indebtedness,  at any time
held or owing by Bank or by any of Bank's affiliates or correspondents to or for
the credit of the account of Pledgor or any  guarantor  or indorser of Pledgor's
Obligation.  
x. 
xi. Pledgor specifically understands and agrees that any sale by
Bank of all or part of the  Collateral  pursuant to the terms of this  Agreement
may be  effected  by Bank at times  and in  manners  which  could  result in the
proceeds of such sale as being significantly and materially less than might have
been  received if such sale had  occurred  at  different  times or in  different
manners,  and Pledgor hereby releases Bank and its officers and  representatives
from and  against  any and all  obligations  and  liabilities  arising out of or
related to the timing or manner of any such sale.  
xii. 
xiii. If, in the opinion
of  Bank,  there  is any  question  that a public  sale or  distribution  of any
Collateral will violate any state or federal  securities law, Bank may offer and
sell such  Collateral in a transaction  exempt from  registration  under federal
securities  law,  and any such sale made in good  faith by Bank  shall be deemed
"commercially reasonable."

1.       GENERAL.
2.
A. PARTIES  BOUND.  Bank's  rights  hereunder  shall inure to the benefit of its
successors and assigns, and in the event of any assignment or transfer of any of
the Obligation or the Collateral, Bank thereafter shall be fully discharged from
any  responsibility  with respect to the Collateral so assigned or  transferred,
but Bank shall retain all rights and powers  hereby given with respect to any of
the  Obligation  or  the  Collateral  not  so  assigned  or   transferred.   All
representations, warranties and agreements of Pledgor if more than one are joint
and several and all shall be binding upon the personal  representatives,  heirs,
successors and assigns of Pledgor.

A. WAIVER.  No delay of Bank 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 Bank of any right  hereunder  or of any  default by Pledgor
shall be binding upon Bank unless in writing, and no failure by Bank to exercise
any power or right  hereunder or waiver of any default by Pledgor  shall operate
as a waiver of any other or  further  exercise  of such right or power or of any
further default.  Each right, power and remedy of Bank as provided for herein or
in any of the loan documents  related to the  Obligation,  or which shall now or
hereafter  exist  at law or in  equity  or by  statute  or  otherwise,  shall be
cumulative  and  concurrent  and shall be in addition to every other such right,
power or remedy. The exercise or beginning of the exercise by Bank of any one or
more of such rights,  powers or remedies shall not preclude the  simultaneous or
later exercise by Bank of any or all other such rights, powers or remedies.
B.
C. 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  Bank and  Pledgor  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. Time is of the essence of this Agreement.

Bank.  The  provisions  of this  Agreement  shall not be  modified or limited by
course  of  conduct  or  usage  of  trade.

unenforceability  or  invalidity of any  provision of this  Agreement  shall not
affect the  enforceability  or validity of any other provision  herein,  and the
invalidity  or  unenforceability  of any  provision of any Loan  Document to any
person or circumstance  shall not affect the  enforceability or validity of such
provision as it may apply to other persons or  circumstances.

expressly  waives  any  objection  as to venue in any  such  location.  Wherever
possible each provision of this Agreement shall be interpreted in such manner as

this Agreement.

         This Rule 144 Rider is made this  10th day of  February,  1998,  and is

the Agreement have the meanings given them in the Agreement.

         1. The securities  listed on Exhibit A hereto,  which Exhibit is made a

         2. Pledgor  represents  and warrants that Pledgor has held the Rule 144
         Securities free and clear of all liens (except for liens,  encumbrances
         and debt  held by Bank)  encumbrances  and  debt,  and  borne  the full
         economic risk thereof since October 12, 1989.

         3. Pledgor covenants and agrees that:

                  a. After an Event of Default,  Pledgor  will  cooperate  fully

                  144  Securities,  including full and complete  compliance with
                  all  requirements  of Rule  144,  and  will  give to Bank  all
                  information  and will do all things  necessary,  including the
                  execution  of all  documents,  forms,  instruments  and  other
                  items,   to  comply  with  Rule  144  for  the   complete  and
                  unrestricted  sale and/or  transfer of the Rule 144 Securities
                  and will  exercise its best efforts to have the issuer of such
                  securities,  upon the request of Bank, take all such action as
                  may be required to satisfy the public information requirements
                  of Rule 144(c).

                  b. Pledgor will not approve or consent to any amendment of the
                  articles of incorporation or charter of any issuer of the Rule
                  144 Securities that may materially  adversely affect the value
                  of the Rule 144  Securities,  or that permit any issuer of the
                  Rule 144 Securities to merge or  consolidate  with or into any
                  corporation or other person, without the prior written consent
                  of Bank.

                  c.  Pledgor  will  use all  reasonable  efforts,  upon  Bank's
                  written  request,  to  have  issuer  publish  all  information
                  necessary  to satisfy  Rule 144 in the event any issuer of the
                  Rule 144  Securities  is not current in its filings  under the
                  Securities  Exchange Act of 1934 at the time of a  foreclosure
                  sale by Bank.

by law),  without  incurring  responsibility  to Guarantor,  without  impairing,
releasing,  or otherwise affecting the obligations of Guarantor,  in whole or in
part,  and without the  endorsement  or execution by Guarantor of any additional
consent,  waiver or guaranty:  (a) change the manner, place or terms of payment;
(b) change or extend the time of or renew or alter,  any Liability or Obligation
or installment thereof, or any security therefor;  (c) loan additional monies or
extend additional credit to Borrower, with or without security, thereby creating
new  Liabilities  or  Obligations  the payment or  performance of which shall be
guaranteed  hereunder,   and  the  Guaranty  herein  made  shall  apply  to  the
Liabilities and Obligations as so changed, extended, surrendered,  realized upon
or otherwise altered; (d) sell, exchange,  release,  surrender,  realize upon or
otherwise  deal with in any  manner  and in any order any  property  at any time

payment  of any  Liability  or  Obligation  of any other  parties  primarily  or
secondarily  liable on any of the  Liabilities  or  Obligations;  (g) release or
compromise  any liability of Guarantor  hereunder or any Liability or Obligation
of any other parties  primarily or secondarily  liable on any of the Liabilities
or Obligations;  or (h) apply any sums from any sources to any Liability without
regard to any Liabilities remaining unpaid.

1. SUBORDINATION. Upon demand of Bank, Guarantor agrees that it will not demand,
take or receive from the Borrower, by set-off or in any other manner, payment of
any liabilities and/or obligations, now and at any time or times hereafter owing
by the Borrower to  Guarantor  unless and until all the  Liabilities  shall have
been  fully  paid,  and any  security  interest,  liens  or  encumbrances  which
Guarantor  now has and from  time to time  hereafter  may  have  upon any of the
assets of the  Borrower  shall be made  subordinate,  junior  and  inferior  and
postponed in priority,  operation and effect to any security interest of Bank in
such assets.
2.
3.  WAIVERS  BY BANK.  No delay  on the  part of Bank in  exercising  any of its
options,  powers or rights,  or any partial or single  exercise  thereof,  shall
constitute a waiver thereof.  No waiver of any of its rights  hereunder,  and no
modification  or amendment of this Guaranty,  shall be deemed to be made by Bank
unless the same shall be in  writing,  duly  signed on behalf of Bank;  and each
such waiver,  if any,  shall apply only with  respect to the  specific  instance
involved,  and shall in no way impair the rights of Bank or the  obligations  of
Guarantor  to Bank in any other  respect at any other time.

5.  TERMINATION.
This Guaranty shall  continue until written notice of revocation  signed by each
respective  Guarantor  or until  written  notice of the death of such  Guarantor
shall  actually  have been  received  by Bank,  notwithstanding  change in name,
location,  composition  or  structure  of, or the  dissolution,  termination  or
increase,  decrease or change in personnel,  owners or partners of Borrower,  or
any one or more of Guarantors,  provided,  however, that no notice of revocation
or  termination  hereof shall  affect in any manner  rights  arising  under this
Guaranty  with  respect  to  Liabilities  or  Obligations  that  shall have been
created, contracted, assumed or incurred prior to receipt of such written notice
pursuant to any agreement  entered into by Bank prior to receipt of such notice,
and the sole effect of such notice of revocation or termination  hereof shall be
to exclude from this Guaranty,  Liabilities or  Obligations  thereafter  arising
that are  unconnected  with  Liabilities or Obligations  theretofore  arising or
transactions   entered  into  theretofore.   
6.  
7. PARTIAL INVALIDITY AND/OR ENFORCEABILITY OF GUARANTY. The unenforceability or
invalidity of any provision of this Guaranty shall not affect the enforceability
or validity of any other provision herein and the invalidity or unenforceability
of  any  provision  of any  Loan  Document  as it may  apply  to any  person  or
circumstance  shall not affect the  enforceability or validity of such provision
as it may apply to other persons or circumstances.
8. 
9. In the event Bank is required to  relinquish or return the
payments, the Collateral or the proceeds thereof, in whole or in part, which had
been previously applied to or retained for application against any Liability, by
reason of a  proceeding  arising  under the  Bankruptcy  Code,  or for any other
reason,   this   Guaranty   shall   automatically   continue  to  be   effective
notwithstanding  any previous  cancellation or release effected by the Bank.

entity.

the  Guarantor  has not  relied  upon any  representation  of the Bank as to the
financial  condition,   operation  or  creditworthiness  of  the  Borrower.  The
Guarantor further agrees that the Bank shall have no duty or responsibility  now

REMEDIES. Upon the occurrence of any event of default hereunder, Bank shall have

party,  under all  applicable  law, and without  limiting the  generality of the
foregoing, Bank may, at its option and without notice of demand: (a) declare any

all or any part of said  Collateral  of Borrower or  Guarantor  at any public or
private sale or otherwise  dispose of any or all of the  Collateral  in its then

therewith Bank may impose reasonable conditions upon any such sale. Bank, unless
prohibited by law the provisions of which cannot be waived,  may purchase all or
any part of said  Collateral to be sold, free from and discharged of all trusts,
claims,  rights  or  redemption  and  equities  of  the  Borrower  or  Guarantor
whatsoever;  Guarantor  acknowledges  and agrees that the sale of any Collateral
through any nationally recognized broker-dealer,  investment banker or any other
method  common  in the  securities  industry  shall  be  deemed  a  commercially
reasonable  sale  under the  Uniform  Commercial  Code or any  other  equivalent
statute or federal law, and expressly  waives notice  thereof except as provided
herein;  and (c) set-off  against any or all  liabilities of Guarantor all money
owed by Bank in any capacity to  Guarantor  whether or not due, and also set-off
against all other Liabilities of Borrower or Guarantor to Bank all money owed by
Bank in any  capacity to any  Borrower or  Guarantor,  and if exercised by Bank,
Bank shall be deemed to have  exercised such right of set-off and to have made a
charge  against any such money  immediately  upon the occurrence of such default
although made or entered on the books subsequent thereto. 
22. 
23. ATTORNEY FEES,
Cost and Expenses.  Guarantor  shall pay all costs of collection  and reasonable
attorney's  fees,  including  reasonable  attorney's fees in connection with any
suit,  mediation or  arbitration  proceeding,  out of court  payment  agreement,
trial, appeal, bankruptcy proceedings or otherwise,  incurred or paid by Bank in
enforcing the payment of any  Liability or enforcing or preserving  any right or
interest of Bank  hereunder,  including the  collection,  preservation,  sale or
delivery  of any  Collateral  from  time to time  pledged  to  Bank,  and  after
deducting such fees, costs and expenses from the proceeds of sale or collection,
Bank may apply any residue to pay any of the  Liabilities  and  Guarantor  shall
continue to be liable for any deficiency  with interest at the rate specified in
any instrument  evidencing the Liability or, at the Bank's option,  equal to the
highest lawful rate,  which shall remain a liability.  
24.
25.  PRESERVATION  OF  PROPERTY.  Bank  shall  not be bound  to take  any  steps
necessary to preserve any rights in any of the property of Guarantor  pledged to
Bank to secure Guarantor's  obligations  against prior parties who may be liable
in connection  therewith,  and  Guarantor  hereby agrees to take any such steps.
Bank,  nevertheless,  at any time, may (a) take any action it deems  appropriate
for the care or  preservation  of such property or of any rights of Guarantor or
Bank therein,  (b) demand,  sue for, collect or receive any money or property at
any time due,  payable  or  receivable  on  account  of or in  exchange  for any
property of Guarantor,  (c) compromise and settle with any person liable on such
property, or (d) extend the time of payment or otherwise change the terms of the
Loan Documents as to any party liable on the Loan Documents,  all without notice
to,  without  incurring  responsibility  to, and  without  affecting  any of the
obligations or liabilities of Guarantor.
26. 
27. Collateral.  Bank shall have a properly perfected security
interest in all of Guarantor's  funds on deposit with Bank to secure the balance
of any liabilities  and/or  obligations  that Guarantor may now or in the future
owe the Bank.  Bank is granted a  contractual  right of set-off  and will not be
liable  for  dishonoring  checks or  withdrawals  where the  exercise  of Bank's
contractual right of set-off or security interest results in insufficient  funds
in  Guarantor's  account.  As authorized by law,  Guarantor  grants to Bank this
contractual  right of set-off and security interest in all property of Guarantor
now or at anytime hereafter in the possession of Bank, including but not limited
to any joint account,  special  account,  account by the entireties,  tenancy in
common,  and all dividends and  distributions now or hereafter in the possession
or control of Bank. 
28. 
29. LIMITATION. It is the intention of Guarantor and the
Bank that the amount of the Liabilities and Obligations  guaranteed by Guarantor
by this Guaranty shall be in, but not in excess of, the maximum amount permitted
by fraudulent  conveyance,  fraudulent transfer or similar laws applicable as to
Guarantor.  Accordingly,  notwithstanding  anything to the contrary contained in
this Guaranty or any other  agreement or instrument  executed in connection with
the payment of any of the  Limitations  and the  Obligations,  the amount of the
Liabilities and the  Obligations  guaranteed by Guarantor by this Guaranty shall
be limited to that amount which after giving effect thereto would not (i) render
Guarantor  insolvent,  (ii) result in the fair  saleable  value of the assets of
Guarantor  being  less  than the  amount  required  to pay its  debts  and other
liabilities  (including  contingent  liabilities) as they mature, or (iii) leave
Guarantor  with  unreasonably  small  capital to carry out its  business  as now
conducted and as proposed to be conducted,  including its capital needs, as such
concepts described in (i), (ii) and (iii) herein are determined under applicable
law, if the  obligations of Guarantor  hereunder  would  otherwise be set aside,
terminated,  annulled  or  avoided  for  such  reason  by a court  of  competent
jurisdiction in a proceeding actually pending before such court. For purposes of
this  Guaranty,  the term  "applicable  law" means as to Guarantor each statute,
law, ordinance,  regulation, order, judgment, injunction or decree of the United
States or any state or commonwealth,  any municipality,  any foreign country, or
any  territory,   possession  or  tribunal  applicable  to  Guarantor.

                            RESTRUCTURING AGREEMENT

                                R E C I T A L S:

guarantees   executed  and  granted  by   Consolidated   and  the   Subsidiaries
(collectively,   the  "Original   Security   Documents"),   including,   without
limitation, those listed on Schedule II attached hereto; and

         WHEREAS,   APS,  Consolidated  and  the  Subsidiaries  of  Consolidated

<PAGE>

the Original Security Documents as security for, among other things,  payment of
the  Existing  Note and  (iii)  Consolidated  and  certain  of the  Subsidiaries
executed and delivered new security  agreements and guarantees  securing,  among
other things, payment of the Existing Note, including, without limitation, those
listed on Schedule II attached  hereto  (all such new  security  agreements  and
guarantees,  together  with the  Refinancing  Agreement,  the Original  Security
Documents,  and all other contracts,  or agreements entered into by Consolidated
and/or its current or former  subsidiaries  and/or  affiliates,  with or for the
benefit  of APS and/or  APS  subsidiaries  and/or  affiliates,  are  hereinafter
collectively referred to as the "Existing Security Documents");

         WHEREAS, Consolidated is in default under the Existing Note and some or
all of the  Subsidiaries  are in  default  under the terms of one or more of the
Existing  Security  Documents,  and, in connection  therewith,  Consolidated and
certain of the  Subsidiaries  have  agreed to  execute  and  deliver  additional
security documents (the "Additional Security Documents")  securing,  among other
things,  full  satisfaction of all amounts owing APS under the Existing Note and
Existing Security Documents; and

         WHEREAS,  Consolidated  has agreed to execute and deliver,  and APS has
conditionally  agreed  to  accept,  but  only  upon  the  terms  and  the  prior
satisfaction of certain  conditions set forth herein, a new note in the original
principal  amount of $2,500,000,  substantially  in the form attached  hereto as
Exhibit A (the  "New  Note"),  in  renewal,  replacement  and  extension  of the
Existing  Note,  which New Note is also to be secured  pursuant to the  Existing
Security Documents and the Additional Security Documents; and

                                       2
<PAGE>

         WHEREAS,  in addition to the covenants and agreements  contained in the
New Note, the Existing Security Documents and the Additional  Security Documents
(together,  the "Security  Documents"),  Consolidated,  the Subsidiaries and APS
desire to  memorialize  certain  other  understandings  and  binding  agreements
between them as provided herein.

         NOW,  THEREFORE,  in  consideration of the foregoing and other good and
valuable  consideration,  the  receipt  and  sufficiency  of  which  are  hereby
acknowledged,  the  parties,  intending  to be legally  bound  hereby,  agree as
follows:

         Section 1.  Acknowledgement of Existing Debt.  Consolidated and each of
the  Subsidiaries  hereby  acknowledge the existence and  enforceability  of the
Existing Note, that all the original principal amount remains due thereunder and
has been accelerated and is now fully due and owing, and that accrued and unpaid
interest  owed  thereunder  to APS through  February 1, 1999,  is  approximately
$731,800.  The principal and interest due APS under the Existing Note,  together
with  any  and  all  expenses,   fees  (including  attorneys'  fees),  costs  of
collection,  and other amounts owed under the Existing Note and any  Transaction
Document,  as defined in Section 7 hereof is collectively  referred to herein as
the "Existing Debt." Consolidated and each of the Subsidiaries  acknowledges and
agrees that Consolidated is currently in default under the Existing Note and one
or more of the Transaction  Documents,  that such default is material,  and that
APS has not previously waived, and does not hereby waive, any breach or default,
or any of its rights, under any of the Transaction Documents.

                                       3
<PAGE>

         Section 2. Acceptance of New Note and Deficiency Obligation. APS agrees
to, upon the expiration of at least eighteen (18) months  immediately  following
the Effective Date, accept in full satisfaction of the Existing Debt (i) the New
Note and (ii) the obligation of Consolidated  and the  Subsidiaries to pay, upon
the terms and conditions hereinafter provided, the deficiency,  (the "Deficiency
Obligation")  between the amount of the New Note and the amount of the  Existing
Debt (as increased by any additional indebtedness arising hereafter under any of
the  Transaction  Documents).  Once APS  accepts the New Note under the terms of
this Agreement, APS agrees that its sole remedy and recourse with respect to the
Deficiency  Obligation will be payment by Consolidated  and the  Subsidiaries of
the  Contingent  Payments  (as  defined in Section 4 hereof)  upon the terms and
conditions provided in Section 4 hereof.  APS's obligation under this Section to
accept the New Note and the Deficiency Obligation in replacement of the Existing
Debt is further qualified by each of the following conditions (subject to waiver
by APS in its sole discretion):

                  (a) Compliance with Existing Agreements.  At the time of APS's
acceptance of the New Note and the Deficiency  Obligation (the "Exchange Date"),
neither  Consolidated  nor any of the Subsidiaries  shall be in default,  and no
event of default shall have previously  occurred since the Effective Date, under
any of the  Transaction  Documents,  except only for:  (i) default in making the
scheduled  payments  described in the  Existing  Note,  (ii)  default  under the
provisions  of the  Refinancing  Agreement  (but not this  Agreement)  requiring
submission of financial information and (iii) the provisions of Section 1 of the
Refinancing Agreement requiring registration of securities of Consolidated; and

                                       4
<PAGE>

                  (b)  Bankruptcy/Insolvency.  At no time prior to and including
the Exchange Date has Consolidated or any Subsidiary:  (i) taken any action that
could impair any collateral  securing the obligations of Consolidated and/or the
Subsidiaries under any of the Transaction Documents (the "Collateral"); (ii) had
a receiver,  trustee or custodian  appointed for, or take  possession of, all or
substantially  all of the assets of such party or any of the Collateral,  either
in a proceeding  brought by such party or in a proceeding  brought  against such
party; (iii) filed a petition for relief under the United States Bankruptcy Code
or any other  present  or future  federal  or state  insolvency,  bankruptcy  or
similar laws (all of the foregoing  hereinafter  collectively called "Applicable
Bankruptcy  Law") or had an  involuntary  petition for relief  filed  against it
under  any  Applicable  Bankruptcy  Law,  or had an order for  relief  naming it
entered  under  any  Applicable   Bankruptcy   Law,  or  had  any   composition,
rearrangement,  extension,  reorganization  or other  relief of  debtors  now or
hereafter  existing  requested  or  consented  to by it; or (iv)  failed to have
discharged  within a period of ten (10) days any  attachment,  sequestration  or
similar writ levied upon,  or any claim  against or  affecting,  any property of
such party; and

                  (c) Minimum Receipts. APS must have been paid a minimum of (i)
all Additional Reimbursable Costs (as defined in Section 11), plus (ii) $375,000
from Consolidated and the Subsidiaries, which $375,000 shall be applied first to
any penalties and interest  accrued and unpaid under the Existing Debt, with any
balance to be applied to  principal;  provided,  that  amounts  retained  by APS
pursuant to Section 3(g) shall count toward the minimum receipts requirement set
forth in this subsection; and

                                       5
<PAGE>

                  (d) Acquisition of Eco-Systems. APS and/or its affiliates must
have  acquired,  through the  Foreclosure  or  otherwise,  all of the issued and
outstanding capital stock or other equity ownership interests of Eco-Systems (as
hereinafter  defined),  and there shall not be outstanding any right on the part
of any person or entity to acquire  any  interest  in the  capital  stock of, or
other equity ownership interest in, Eco-Systems.

         Section 3.        Acquisition of Eco-Systems.

                  (a)  Foreclosure.  Consolidated  and  each  Subsidiary  hereby
agrees that APS is entitled to foreclose (the  "Foreclosure")  on the issued and
outstanding   capital  stock  of  Eco   Acquisition,   Inc.  d/b/a   Eco-Systems
("Eco-Systems"),  an Arkansas  corporation,  pursuant to that certain Assignment
and  Security  Agreement  dated  November  6,  1997,  by  and  between  APS  and
Consolidated  (the  "Eco-Systems  Security  Agreement").  Consolidated  and each
Subsidiary (including, without limitation,  Eco-Systems) acknowledges and agrees
that there exists under the Eco-Systems  Security  Agreement an Event of Default
(as  defined  therein),  and as of the  date of this  Agreement,  such  Event of
Default has not been cured. Consolidated and each Subsidiary, including, without
limitation,  Eco-Systems,  further  agrees to  cooperate  fully  with APS in the
Foreclosure,  and to not take any action which could adversely  impact the value
of Eco-Systems up to, and/or after, the Foreclosure.  Accordingly,  Consolidated
and each  Subsidiary  acknowledges  and agrees that any sale conducted by APS or
one  of its  affiliates  under  the  Eco-Systems  Security  Agreement  and  this
Agreement  is  hereby  accepted  by  Consolidated   and  each  Subsidiary  as  a
commercially  reasonable  sale.  APS or one of  its  affiliates  may  bid on the
collateral under the Eco-Systems  Security Agreement at the sale, whether public

                                       6
<PAGE>

or private,  and in the event it is the  successful  bidder,  all parties hereby
agree  that  such  purchase  shall  not  be  a  discharge  or   satisfaction  of
Consolidated's or any Subsidiary's  obligations under Section 9.505 of the Texas
UCC (Texas  Business  and Commerce  Code).  Furthermore,  Consolidated  and each
Subsidiary  hereby renounces any right to notification of the  Foreclosure.  Any
amount of value or credit  arising from the  Foreclosure  will be applied to the
Existing  Debt  pursuant  to the  terms  of  the  applicable  Existing  Security
Documents and will, in no event,  reduce the original  amount of, or any amounts
due under, the New Note.

                  (b) Limitation on Foreclosure.  Notwithstanding  the foregoing
provisions  of  subsection  (a),  APS  agrees  that it will not  consummate  the
Foreclosure prior to April 1, 1999 as long as the following conditions are met:

                           (i)Compliance with Existing  Agreements. Consolidated
and each of the  Subsidiaries  complies  in all  respects  with  its  respective
obligations  under  each of the  Transaction  Documents  to  which it is a party
(except  for  obligations  to make  the  scheduled  payments  called  for in the
Existing Note); and
                           (ii)   Distributions.   Without  the  prior   written
approval of APS in each instance, Eco-Systems does not
distribute  any cash or other  assets to  Consolidated,  another  Subsidiary  or
(except to pay the  obligations  and  expenses  of  Eco-Systems  incurred in the
ordinary course of business) any third party.

                                       7
<PAGE>

                           (iii) Access. APS and its  representatives is allowed
free and complete access to books, records,
employees,  officers,  directors  and  assets of  Eco-Systems  for  purposes  of
evaluating the business, prospects, financial condition, continued viability and
value of Eco-Systems.

                  (c) Indemnification. Consolidated and each Subsidiary, jointly
and severally,  hereby agrees to indemnify and hold harmless (i) APS, and all of
APS's affiliates, subsidiaries, employees, officers, directors, shareholders and
representatives (collectively,  the "APS Indemnified Parties"), from and against
any and all damages,  losses,  claims,  liabilities,  demands,  charges,  suits,
penalties, costs and expenses (including, without limitation, any and all taxes,

with the  commencement or assertion of any action,  proceeding,  demand or claim
arising out of the  Foreclosure  or the ownership of any interest in Eco-Systems
upon and after the  Foreclosure  and that is related to or arises,  directly  or
indirectly,  in whole or in part,  out of  matters  occurring  or  circumstances
existing  on or prior  to the date of the  Foreclosure  and (ii)  APS,  each APS
Indemnified Party and Eco-Systems from and against any and all Indemnified Costs
that are (A) incurred by, or asserted against,  Eco-Systems,  (B) related to any
act or omission by or on behalf of  Eco-Systems,  Consolidated or any Subsidiary
occurring on or prior to the date of Foreclosure, and (C) that are not reflected
by amount,  or included  within an amount,  shown as a liability  on the balance
sheet of Eco-Systems dated January 31, 1999 and provided to APS by Consolidated,
a copy of which is attached  hereto as Exhibit B.  Furthermore,  any Indemnified
Cost incurred by APS or  Eco-Systems  that is not 

                                       8
<PAGE>

promptly paid or reimbursed by
Consolidated  pursuant to this Section  shall bear interest at an annual rate of
ten percent (10%).

                  (d) Issuance of Employee  Stock  Options.  All parties  hereto
acknowledge  and  agree  that,  after the  Foreclosure,  Eco-Systems  may,  from
time-to-time,  issue employee stock options to its  directors,  officers  and/or
employees  on such  terms  and  conditions  as may be  approved  by the Board of
Directors  of  Eco-Systems.  APS  agrees  that  it  will,  during  the  six  (6)
consecutive month period beginning on the Effective Date, and only to the extent
allowed under applicable law, take all actions necessary to prevent the grant of
any and all employee stock options by Eco-Systems  without the prior approval of
Jim Connors in each instance.

                  (e)   Allocation   of   Expenses   and   Corporate   Overhead.
Consolidated and each of the Subsidiaries  acknowledges and agrees that, for any
period  during  which APS owns a  controlling  interest in  Eco-Systems,  APS is
entitled  to  allocate  to  and  charge   Eco-Systems   for,   and  receive  the
corresponding  payment  for (i)  direct  and  indirect  costs for  services  and
products provided to Eco-Systems by APS or one of its affiliates, (ii) corporate
overhead associated with accounting costs, employee benefit administration costs
and  executive  or  manager  salaries,  incurred  by  APS  and  attributable  to
Eco-Systems,  together  with such  other  corporate  overhead  allocation  as is
consistent  with the past  practices of APS and its  subsidiaries  and (iii) the
amount  of any and  all  other  costs,  expenses,  fees,  liabilities  or  other
obligations  that are  incurred by APS or one of its  affiliates,  to the extent
that such amounts benefit Eco-Systems, directly or indirectly. The parties agree
that no  allocation to or payment by  Eco-Systems  pursuant to this Section will
constitute  payment  of any of their  obligations  under any of the  Transaction

                                       9
<PAGE>

Documents (including, without limitation, obligations under the Existing Debt or
the New Note, as the case may be).

                  (f) Restricted  Payments.  Consolidated,  Eco-Systems  and APS
each  agree  that any  payments  made by  Eco-Systems  to Sam  Sexton  after the
Foreclosure,  regardless  of whether such payments are  compensatory  in nature,
shall be  restricted  for all  purposes to no greater than $10,000 per month and
shall  count  toward  the  payment  obligations  of APS set forth in the  second
paragraph of Section 3(g). Consolidated,  Eco-Systems and APS each further agree
that after October 15, 1999,  Eco-Systems will not be obligated in any manner to
pay any amounts to Sam Sexton,  as  compensation  or otherwise,  except for such
salary  and  benefits  as have been  approved  in  writing  by the then  current
officers of Eco-Systems.

                  (g) Application of Post-Foreclosure Proceeds. APS agrees that,
after the  Foreclosure,  APS will  apply  any cash  dividends  distributed  from
Eco-Systems to APS, or such subsidiaries of APS who then own equity interests in
Eco-Systems, first to satisfaction of all Additional Reimbursable Costs and then
to  satisfaction of interest and principal under the Existing Debt, or, once the
New Note has been  accepted by APS pursuant  hereto,  to interest and  principal
owed under the New Note. But in the event that, prior to APS's acceptance of the
New  Note,  APS  receives  cash  dividends  paid  pursuant  to this  Section  by
Eco-Systems  (excluding  any portion of such amounts  paid over to  Consolidated
pursuant  to  this  Section)  in  excess  of  the  sum  of  (i)  all  Additional
Reimbursable Costs, plus (ii) $375,000,  then any such excess amount will not be
applied to the Existing  Debt, but will rather be applied by APS as a contingent
prepayment  of the New Note  (contingent  only upon APS's  acceptance of the New

                                       10
<PAGE>

Note);  provided,  however,  that such  excess  amount  will be  applied  to the
Existing Debt in the event that APS does not accept the New Note.

                  APS further  agrees that it will pay to  Consolidated  (or its
designee)  one-half of all cash dividends received on or before October 14, 1999
in  respect  of  APS's  or  APS's   subsidiaries'   ownership  of   Eco-Systems.
Notwithstanding  the  foregoing  or  any  other  provision  of  this  Agreement,
Consolidated  acknowledges  and agrees that amounts paid to Consolidated (or its
designee)  pursuant to the  immediately  preceding  sentence will not be applied
against the Existing  Debt or the New Note, as the case may be. In the event APS
acquires, directly or indirectly, all ownership interests in Eco-Systems through
the  Foreclosure,  APS  agrees  that it will  use  reasonable  efforts  to cause
Eco-Systems  to  distribute  as  dividends  all excess  cash that is  reasonably
available for distribution (using commercially  prudent business judgment) after
payment of Eco-Systems' obligations and expenses and establishment of reasonable
reserves.

                  (h) Repurchase Option.  Consolidated is hereby granted a right
to purchase from APS or its  affiliates  all (but only all) of the capital stock
of Eco-Systems that may have been acquired by APS or its affiliates  through the
Foreclosure (the "Repurchase  Option").  But the Repurchase Option is subject to
the following terms and conditions: (i) APS must have accepted the New Note upon
satisfaction of the terms and conditions set forth in this  Agreement,  (ii) all
amounts  outstanding  under the New Note,  including all interest  thereon shall
have been paid, (iii)  Consolidated and each of the Subsidiaries must have fully
complied  with all of the terms of this  Agreement and the  Additional  Security
Documents,  including, without limitation, the payment of all amounts due to any
APS Indemnified  Parties and Eco-Systems  pursuant to the indemnity  obligations


                                       11
<PAGE>

under  Section 3(c)  (including  any interest  provided for  therein),  (iv) the
Repurchase  Option,  if available,  must be exercised prior to the expiration of
six (6) months  immediately  following the full satisfaction of all amounts owed
under the New Note, (v) the purchase  price of $1,000 in  immediately  available
funds must be  tendered  at the  closing  of the  conveyance  allowed  under the
Repurchase  Option,  and (vi)  Consolidated and each Subsidiary must execute and
deliver  at the  closing  a general  release  of  liability  in favor of all APS
Indemnified  Parties,  and  such  other  documents  and  instruments  as APS may
request.

         Section 4. Contingent Payments.  Consolidated and the Subsidiaries each
agree that the payments set forth in this Section (each a "Contingent  Payment")
will be made upon the occurrence of the events triggering such payments,  all as
more fully  described  in  subsections  (a)  through (c) below.  Any  Contingent
Payment  received by APS or one of its  affiliates is to be applied as set forth
in the applicable subsection which describes the Contingent Payment obligation.

                  (a) Payment Upon  Disposition  of  Interests in  Subsidiaries.
Consolidated  agrees that it must have APS's prior written approval for any sale
or  disposition  of either the stock or the assets (or any  portion  thereof) of
Exsorbet  Technical  Services,  Inc., an Arkansas  corporation doing business as
SpilTech Services, Inc. ("SpilTech"), KR Industrial Service of Alabama, Inc., an
Alabama  corporation  ("KR") or any other Subsidiary.  Assuming any such sale is
negotiated on arms-length  terms, APS will agree to give such approval  provided
Consolidated   first  notifies  APS  in  writing  of  the  possibility  of  such
disposition  and provides APS (prior to execution)  with copies of the documents
governing  such   disposition.   Consolidated   

                                       12
<PAGE>

acknowledges  and  agrees  that,
notwithstanding the foregoing or any other provision of this Agreement, any such
disposition  is, and remains  after the  Effective  Date,  prohibited  under the
Transaction  Documents,  absent the express prior written consent of APS in each
instance.

                  Consolidated  further agrees that, with respect to any sale of
the stock or assets of either  SpilTech or KR, such  documents must provide that
seventy-five  percent  (75%) of the net proceeds  from such  disposition  (after
payment of only perfected secured  indebtedness  which is senior to the liens of
APS) will be paid directly to APS at the closing of the disposition,  limited in
amount,  however,  to  the  aggregate  of  all  amounts  then  owing  to  APS by
Consolidated and the Subsidiaries.  APS agrees that it will apply any Contingent
Payment  received  pursuant  to this  subsection  first to  satisfaction  of all
Additional Reimbursable Costs and then to satisfaction of interest and principal
under the Existing Debt, or, once the New Note has been accepted by APS pursuant
hereto,  to interest  and  principal  owed under the New Note.  But in the event
that,  prior  to  APS's  acceptance  of the  New  Note,  APS  receives  combined
Contingent  Payments  pursuant to this subsection and dividends from Eco-Systems
that it may retain  pursuant  to Section  3(g),  in excess of the sum of (i) all
Additional  Reimbursable Costs, plus (ii) $375,000,  then any such excess amount
will not be applied to the Existing Debt, but will rather be applied by APS as a
contingent  prepayment of the New Note (contingent only upon APS's acceptance of
the New Note); provided, however, that such excess amount will be applied to the
Existing Debt in the event that APS does not accept the New Note.

                  (b) Payment Upon  Disposition  of  Interests in  Consolidated.
Consolidated  agrees that prior to any sale, change of control  transaction,  or
other disposition (by merger, 

                                       13
<PAGE>

consolidation or otherwise) of either its stock or
its assets (or any portion thereof),  Consolidated will notify APS in writing of
the  possibility of such  disposition  and provide APS (prior to execution) with
copies of the documents  governing such disposition.  Consolidated  acknowledges
and agrees that,  notwithstanding  the foregoing or any other  provision of this
Agreement,  any such  disposition  is, and  remains  after the  Effective  Date,
prohibited  under the  Transaction  Documents,  absent the express prior written
consent of APS in each instance.

                  Consolidated   agrees  that  the  documents   governing   such
disposition  must provide that  seventy-five  percent  (75%) of the net proceeds
from  such  disposition  (prior  to any  payment  or other  consideration  being
received  by any  direct or  indirect  shareholders  or  controlling  persons of
Consolidated) will be paid to APS at the closing of the disposition,  limited in
amount,  however,  to  $600,000.  APS agrees  that it will apply any  Contingent
Payment  received  pursuant to this  subsection to  satisfaction of interest and
principal  under the Existing  Debt,  or, once the New Note has been accepted by
APS pursuant hereto, to the Deficiency Obligation. In no event will amounts paid
under this subsection be applied to the New Note.

                  Notwithstanding  the foregoing or any other  provision of this
Agreement to the contrary,  this  subsection  (b) shall not apply to any sale of
stock of either KR or SpilTech as long as the Contingent Payment  obligations in
Section 4(a) have been fully satisfied with respect to such sale of stock.

                  (c) Payment  Upon  Settlement  of Everen  Securities  Lawsuit.
Consolidated and the Subsidiaries agree to pay to APS seventy-five percent (75%)
of the total cash proceeds 

                                       14
<PAGE>

payable to them (after  deduction of only legal fees
and up to $75,000  payable to American  Dynasty  Insurance  Company),  by way of
settlement,  judgment or otherwise,  out of or in relation to any litigation and
claims (whether or not asserted as of the Effective Date, but including, without
limitation,  the  litigation  pending  on the  Effective  Date)  between  Everen
Securities  and/or  any of its  affiliates  or  insurers  on the  one  hand  and
Consolidated  and/or any of its affiliates on the other hand, limited in amount,
however,  to $600,000.  Consolidated and the  Subsidiaries  agree that they will
promptly pay such amounts to APS upon receipt and will not dispose of, settle or
agree to the entry of any  judgment  without the prior  written  consent of APS;
provided,  however,  that such consent may not be withheld if such  disposition,
settlement or judgment  explicitly provides for immediate payment of $600,000 to
APS  pursuant  to this  Section.  APS agrees  that it will apply any  Contingent
Payment  received  pursuant to this  subsection to  satisfaction of interest and
principal  under the Existing  Debt,  or, once the New Note has been accepted by
APS pursuant hereto, to the Deficiency Obligation. In no event will amounts paid
under this subsection be applied to the New Note.

         Consolidated  agrees  that it must  provide  APS with at least ten (10)
days  opportunity,  prior to the  closing of any  disposition  described  in the
foregoing  subsections  (a) or (b), or prior to  finalizing  any  settlement  or
judgment described in subsection (c), and after receipt by APS of all documents,
instruments and agreements related to such disposition,  settlement or judgment,
to review the terms and  conditions  of such and to ensure  compliance  with the
conditions  imposed under this Agreement and under any of the other  Transaction
Documents. Furthermore, Consolidated agrees to cooperate with APS and to provide
APS access  to,  and  participation  in,  the  closing of any such  disposition,
settlement  or judgment all as  requested  by APS in order to ensure  compliance


                                       15
<PAGE>

with the terms and conditions of the Transaction  Documents.  Upon any breach by
Consolidated of the terms and provisions of this Section,  the entire Deficiency
Obligation shall  automatically  become  immediately due and payable without any
limitation on the source of repayment as otherwise provided herein.

         Section 5.        Additional Covenants.

                  (a)  Future  Subsidiaries.  Consolidated  and each  Subsidiary
agrees that it will take any and all actions  that may be necessary to cause any
future corporations or other entities that become owned or controlled, wholly or
partially,  directly or indirectly, by Consolidated or that Subsidiary after the
Effective  Date  to  execute  and  deliver  to APS  (i) a  counterpart  to  this
Agreement,  and (ii) a payment and  performance  guaranty  agreement and a first
lien  security  agreement  on all of its  assets,  each for the  benefit  of APS
covering  all  payment  and   performance   obligations  of   Consolidated,   in
substantially the same form of the guaranty  agreements and security  agreements
executed  by the  Subsidiaries  that are  included  in the  Security  Documents.
Consolidated and each Subsidiary  further agrees that, with respect to each such
newly owned or controlled corporation or entity, it will (i) execute and deliver
to APS a first lien,  perfected  security  interest in and to all of the capital
stock or other equity  interests held by  Consolidated or the Subsidiary in that
entity  and (ii) take any and all other  actions as may be  necessary  to ensure
that such entity is considered a Subsidiary hereunder for all purposes.

                  (b)  Dismissal  of Lawsuit.  APS agrees to dismiss,  within 10
business  days of the  Effective  Date,  the  existing  lawsuit  by APS  against
Consolidated. Such dismissal, however, 

                                       16
<PAGE>

will be without prejudice and without any
limitation  on  the  refiling  of  the  same  or  other  lawsuits  by APS or its
affiliates  against  Consolidated,  any  Subsidiary  or any of their  respective
affiliates.

                  (c)   Existing   Covenants   Under   Transaction    Documents.
Consolidated  and each of the  Subsidiaries  covenants  and agrees  that it will
continue  to  comply  with all of the  covenants  set  forth in the  Transaction
Documents to which it is a party.

                  (d)  Other  Agreements.  Consolidated  agrees to  execute  and
deliver,  concurrently  with its execution and delivery of this  Agreement,  the
Assignment and Security  Agreement attached hereto as Exhibit C and the Security
Agreement  attached hereto as Exhibit D, both of which, for all purposes hereof,
shall be  deemed  to be  included  within  the  Additional  Security  Documents.
Furthermore, each of Eco-Systems, SpilTech and KR agrees to execute and deliver,
concurrently  with its  execution  and  delivery of this  Agreement,  a Security
Agreement in a form attached hereto as Exhibit E, which shall,  for all purposes
of this Agreement, be considered included in the Additional Security Documents.

                  (e)  Financial  Reporting  Requirements.  In  addition to such
financial and other reporting  requirements  as may be provided  pursuant to the
Transaction Documents, Consolidated covenants and agrees that it will, after the
date of this Agreement,  provide to APS true and correct copies of all financial
statements, reports or summaries concerning the business, financial condition or
operations of Consolidated or any of the  Subsidiaries  (or Consolidated and the
Subsidiaries  on  a  consolidated  basis),  within  ten  (10)  days  after  such
statements, reports or summaries become available to Consolidated.  Furthermore,
any such  statements,  reports or 

                                       17
<PAGE>

summaries  shall  contain a written  statement
signed by the Chief  Financial  Officer of  Consolidated  to the effect that the
financial  information  contained  therein has been prepared in accordance  with
generally accepted accounting  principles,  consistently  applied, and is fairly
and accurately presented.

                  (f) Consolidated and Eco-Systems each agree that they will (i)
vigorously   contest  any  lawsuit,   claim  or  action  filed  against   either
Consolidated or Eco-Systems by former accountants of Consolidated and (ii) allow
APS full participation in the defense of any such lawsuit, claim or action.

         Section 6. No Additional Financings.  The parties acknowledge and agree
that  certain of the  Transaction  Documents  provide  that,  without  the prior
consent of APS, neither  Consolidated  nor any of the Subsidiaries  will create,
incur,  assume or become liable in any manner for any indebtedness (for borrowed
money, deferred payment for the purchase of assets, lease payments, as surety or
guaranty of the debt of another,  or otherwise)  other than to APS, except trade
debts incurred in the ordinary  course of business.  The parties hereto covenant
and agree that such provisions of the Transaction  Documents  remaining  binding
and enforceable in all respects,  are to be broadly construed for the benefit of
APS,  and that the  prohibitions  on creating,  incurring,  assuming or becoming
liable  for,  any  indebtedness,  etc.,  shall be  deemed to  preclude,  without
limitation,  not only traditional  methods of financing,  but also financings in
the form of factoring, assets securitizations,  sale and lease backs, financings
through the  issuance  of equity  securities,  debt  securities  or  convertible
securities,  debenture or bond  financings  and all other forms of financing and
borrowing,  except for open  account  trade  payables  incurred in the  ordinary

                                       18
<PAGE>

course of business;  provided,  however that the following will not be deemed to
constitute a violation of the foregoing prohibition:  (i) factoring transactions
that occurred  prior to October 15, 1997, so long as there has not since October
15, 1997 been, and there is not after the date of this  Agreement,  any increase
in the  amounts  due or  involved  in  such  factoring  relationships  and  (ii)
refinancing of existing  obligations (but only those existing  obligations which
are themselves not in violation of any of the Transaction Documents), so long as
there is not any increase in amounts due under such existing obligations.

         Section 7.   Representations  and Warranties.  Consolidated and each of
the Subsidiaries  hereby,  jointly and severally, represents and warrants to APS
(as of the Effective Date), and covenants with APS, as follows:

                  (a) Consolidated and each of the Subsidiaries is a corporation
duly  organized,  validly  existing,  and in good standing under the laws of the
state of their  incorporation,  and has full  corporate  power and  authority to
carry  on its  business  as now  conducted,  to  enter  into  and  perform  this
Agreement,  and to perform  all of its  obligations  under and  pursuant to this
Agreement, the Existing Note, the Refinancing Agreement, each Security Document,
and  each  other  document,  agreement,   contract,  instrument  or  certificate
contemplated  by or  executed  and  delivered  in  connection  with  any  of the
foregoing,  including, without limitation, the New Note (if issued and accepted)
and those  certain  agreements  referred to in Section 5(d) above and in Section
7(g)  below   (collectively,   including  this   Agreement,   the   "Transaction
Documents"), to which it is a party.

                                       19
<PAGE>

                  (b) This  Agreement  has been  duly  and  validly  authorized,
executed  and  delivered  by  Consolidated  and  each of the  Subsidiaries,  and
constitutes  the valid and binding  obligation of  Consolidated  and each of the
Subsidiaries,   enforceable   against  them  in   accordance   with  its  terms.
Furthermore,  each of the Transaction Documents is, or will be when executed and
delivered,  the valid and binding  obligation of the parties thereto (other than
APS),  enforceable  against the parties  thereto  (other than APS) in accordance
with its respective terms.

                  (c) There is only one class of capital stock of  Consolidated,
Eco-Systems, SpilTech and KR outstanding.

                  (d)    Consolidated's    and   each   of   the   Subsidiaries'
representations and warranties under each of the Transaction  Documents to which
they are parties was true and correct when made, and remains true and correct as
of the Effective Date of this Agreement.

                  (e) The entering into,  and delivery and  performance of their
obligations  under,  the  Transaction  Documents  does not,  and will  not,  (i)
conflict with or constitute a breach of, or default  under,  any  organizational
document, bylaw, contract, agreement or obligation applicable to Consolidated or
any of the  Subsidiaries or (ii) require any notice to,  declaration,  filing or
registration   with,  or  permit  or  consent  from,  any  domestic  or  foreign
governmental  or regulatory  body or  authority,  or any other person or entity,
including,  without limitation,  any party to any contract or agreement by which
Consolidated  or any Subsidiary is bound or any approval by the  shareholders of
Consolidated or any Subsidiary.

                                       20
<PAGE>

                  (f)  Following  the  Foreclosure  described  in  Section  3(a)
hereof, APS will,  directly or indirectly,  enjoy sole and exclusive  ownership,
free and  clear  of any  liens or  encumbrances,  of any and all of the  capital
stock, of all classes,  of Eco-Systems.  Furthermore,  APS will enjoy all of the
rights and  benefits of stock  ownership  with  respect to any shares of capital
stock of  Eco-Systems  acquired  through  the  Foreclosure,  including,  without
limitation,  the sole and exclusive right to elect new directors and to amend or
replace existing (or adopt new) stock option plans.

                  (g)  Consolidated  and  Eco-Systems,  jointly  and  severally,
represent  and  warrant  that Jim  Connors  has been  fully and  unconditionally
released  from  his  employment  with  Consolidated  and  that he is free of any
contract, agreement, understanding or other restraint that could be construed as
prohibiting  his full time employment  with  Eco-Systems  after the date of this
Agreement.  Consolidated and Eco-Systems,  jointly and severally,  represent and
warrant  that,  except as set forth and  described in detail on (or attached to)
Schedule III,  there are no contracts or agreements  relating to the  employment
(as  an  employee,  independent  contractor,  consultant  or  otherwise)  of any
individual by  Eco-Systems,  and each of them  covenants and agrees not to allow
any such contract or agreement to be entered into hereafter  without APS's prior
written consent.

                  (h) Consolidated  and each Subsidiary  acknowledges and agrees
that execution and delivery of each of the Transaction  Documents required to be
executed by it under this  Agreement  (or any other  Transaction  Document) is a
condition to each and every obligation of APS under this Agreement.

                                       21
<PAGE>

                  (i) Consolidated and each Subsidiary has supplied APS with all
information  necessary for APS to conduct appropriate lien searches with respect
to any and all property owned by Consolidated and each Subsidiary,  and Schedule
IV attached hereto contains the location of both the principal place of business
(by city) and all  property  (by  county  and  state) of  Consolidated  and each
Subsidiary.

         Section 8. Release. The parties being released by Consolidated and each
of the  Subsidiaries  by virtue of this  Section,  all of whom are  collectively
referred to herein as the "Released Parties", are APS, Eco-Systems, Jim Connors,
their principals,  shareholders, partners, members, directors, officers, agents,
employees,  spouses,  children,  servants,  insurers,  employee  welfare benefit
plans,  pension and/or deferred  compensation  plans,  administrators  and other
fiduciaries, parent companies, affiliated entities, subsidiaries, successors and
assigns,  and  each  of  them,  individually  and  collectively  (in  each  case
excluding, however, Consolidated and the Subsidiaries other than Eco-Systems).

                  (a)  Release by  Consolidated  and the  Subsidiaries.  Each of
Consolidated  and the  Subsidiaries  hereby releases and discharges the Released
Parties (the "Release"),  individually and collectively, of and from any and all
claims, causes of action, suits, debts, contracts,  agreements (including,  with
respect  to  Jim  Connors,  and  without  limitation,  any  existing  employment
agreement between Jim Connors and Consolidated),  promises,  liability, demands,
damages, and other expenses of any nature whatsoever, at law or in equity, known
or  unknown,  fixed  or  contingent,  contemplated  or  uncontemplated,  whether
asserted or assertable,  arising out 

                                       22
<PAGE>

of any matter whatsoever which has occurred
from the  beginning of time up through and  including  the date hereof.  Without
limiting  the  generality  of  the  foregoing,  each  of  Consolidated  and  the
Subsidiaries  hereby  acknowledges  and agrees  that the  Release is intended to
waive and  discharge any and all actions,  claims,  demands and causes of action
arising out of or in any way related to its prior relationship with the Released
Parties.  But the foregoing provisions do not, and should not be construed so as
to, alter,  amend or negate the  enforceability  of this  Agreement or any other
Transaction Document.

                  (b) Construction.  The Release is intended to be and should be
construed as a general, complete and final waiver and release of all claims. The
Release is being made and executed by each of Consolidated  and the Subsidiaries
individually  and on behalf of its  successors,  assigns,  agents,  all  persons
subrogated to its rights or to whom its rights are secondary or derivative,  and
all other persons on behalf of whom it is authorized to act.

                  (c) No Admissions.  It is expressly understood and agreed that
neither this Agreement,  the Release,  nor the furnishing of  consideration  for
this Agreement or the Release,  shall be deemed or construed at any time for any
purpose as an admission by anyone of  wrongdoing  or liability of any kind,  all
such wrongdoing and liability being expressly denied.

                  (d)  Knowledge  of  Claims.   Each  of  Consolidated  and  the
Subsidiaries  expressly  warrants and stipulates that it intends for the Release
to release any and all claims that it may now have against the Released Parties,
regardless of whether such claims have been 

                                       23
<PAGE>

asserted and  regardless of whether
such claims  arise out of or are related in any way to any facts in existence on
or before the date of this Agreement.

         Section 9. Further Assurances.  Consolidated and each Subsidiary agrees
to cooperate fully with APS, and to take such steps and execute and deliver such
documents,  instruments  or  certificates  as may be  necessary to carry out, or
further evidence, its obligations under this Agreement.

         Section 10. Effect of Agreement.  The parties  hereto  acknowledge  and
agree  that this  Agreement  does not  constitute  an  amendment,  modification,
replacement or limitation on any of APS' rights under and pursuant to any of the
Transaction Documents,  and all of the Transaction Documents are intended to be,
and  remain,  binding  and  enforceable  in  accordance  with their  terms.  The
Transaction  Documents  are  intended  to be  construed  consistently  with this
Agreement.  However,  in the event of a direct conflict between the terms of any
of the  Transaction  Documents and this  Agreement,  the terms of this Agreement
shall control.  Consolidated and each of the Subsidiaries represents,  warrants,
covenants  and  agrees  that (i) APS has not  breached  or  defaulted  under any
contractual obligations to any of them, and (ii) there are no defenses available
to Consolidated or any of the Subsidiaries  against the  enforceability  of each
and every of their obligations under the Transaction Documents.

         Without limiting the foregoing, and except as expressly provided in any
release  arising out of that certain action filed in the United States  District
Court for the Western District of Texas, Austin Division,  Case No. A98CA375-SS,
Consolidated and each of the Subsidiaries 

                                       24
<PAGE>

expressly acknowledges and agrees that
APS is not  relinquishing,  waiving or otherwise  modifying any right,  claim or
cause  of  action  it  has  or  may  have,  against  Consolidated  or any of the
Subsidiaries or any of their affiliates,  directors,  officers,  shareholders or
employees,  including,  without limitation, any such claims, rights or causes of
action related to the negotiation  and entering into the various  agreements and
transactions  which  gave  rise  to  any of the  Transaction  Documents,  or any
misrepresentation  made  in  connection  therewith,  or any  breach  or  default
thereunder.

         Consolidated and the  Subsidiaries  agree to an extension or tolling of
all defenses based on the passage of time, including but not limited to statutes
of limitation and  principles of laches,  applicable or relating to any possible
claims,  demand, and/or cause of action which APS may have that arises out of or
in connection  with any of the  Transaction  Documents  any of the  transactions
giving  rise to the  Original  Note or any other  transaction,  act or  omission
involving  APS  or  any  of  the  APS  Indemnified  Parties,  or  the  promises,
warranties,  inducements,  or  representations  in  connection  therewith.  Such
tolling and extension of the time in which APS may bring any such claim, demand,
and/or cause of action shall extend until the Existing  Debt, or all amounts due
under the New Note and  Deficiency  Obligation  (if the New Note is issued) have
been paid in full.

         Section 11.  Reimbursement of Expenses.  Without in any way reducing or
otherwise limiting any of Consolidated's or the Subsidiaries'  other obligations
to reimburse expenses pursuant to any of the Transaction Documents or otherwise,
Consolidated  agrees to reimburse APS for (i) $45,000 previously advanced by APS
or its  affiliates on behalf of  Consolidated,  

                                       25
<PAGE>

(ii) all legal,  accounting  and
other costs,  fees and expenses  incurred by APS in  negotiating,  preparing and
entering into this Agreement and the other Transaction Documents, and perfecting
the various  security  interests  granted  pursuant thereto and (iii) all legal,
accounting  and other  costs,  fees and  expenses  incurred by APS or one of its
affiliates  at any time after March 1, 1999 and arising out of or related to the
transactions contemplated in this Agreement. All amounts for which reimbursement
is due under this Section are collectively referred to herein as the "Additional
Reimbursable Costs."

         Section  12.  Remedies.  This  Agreement  may be  enforced at law or in
equity,  including,  but not limited to,  injunctive  relief. In case any one or
more of the provisions of this Agreement  shall,  for any reason,  be held to be
invalid,  illegal or unenforceable in any respect, any other provision hereof in
this Agreement shall be construed as if such invalid,  illegal, or unenforceable
provision  had  never  been   contained   herein.   Such  invalid,   illegal  or
unenforceable  provisions  shall be given  effect  to the  maximum  extent  then
permitted by law.  Consolidated  and the  Subsidiaries  shall be deemed to be in
joint and several default under this Agreement if there is any default under any
of the Transaction Documents.

         Section 13.  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.

                                       26
<PAGE>

         Section 14.       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.

         Section 15. Inurement. This Agreement shall be binding upon the parties
hereto  and  their  respective  heirs,  legal  representatives,  successors  and
permitted  assigns.  This Agreement  shall not be assignable by any party hereto
(other  than APS)  without  the  express  prior  written  consent of APS in each
instance.  Upon written  notice to  Consolidated,  APS may assign its rights and
obligations under this Agreement.

         Section 16.  Limitation on Interest:  Maximum  Rate.  The parties agree
that,  with  respect to any and all lending  provisions  contained in any of the
Transaction  Documents,  they  intend  to  contract  in strict  compliance  with
applicable usury law from time to time in effect.  To effectuate this intention,
the parties  acknowledge  and agree that none of the terms and provisions of any
of the Transaction Documents,  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 (as hereinafter  defined).  If,
from any possible  construction  of any  Transaction  Document,  interest  would
otherwise be payable to the lender thereunder 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 the lender
thereunder  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 the borrower, endorsers or other persons that now or hereafter
become  liable for payment of any  obligation  referred to 

                                       27
<PAGE>

herein  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.  Any party that
is a lender  under any  Transaction  Document and any  subsequent  holder of the
related loan expressly  disavows any intention to charge or collect  unearned or
excessive interest or finance charges in the event the maturity of such loan, is
accelerated. If the maturity of such loan is accelerated for any reason, whether
as a result  of a  default  under  the  loan,  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 such
lender or any  subsequent  holder of the loan  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 the borrower  thereunder.
In the event such  lender or any  subsequent  holder of the loan 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 loan,  and, if the  principal  balances of the loan is
paid in full, any remaining excess shall be paid to the borrower thereunder.  In
determining  whether  or not the  interest  paid or payable  under the  specific
contingencies  exceeds the Maximum Rate allowed by applicable  law, the borrower
and  the  lender  thereunder  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 loan (as it may be renewed and extended) so that the interest rate is
uniform throughout the entire term of the loan. The terms and provisions of this

                                       28
<PAGE>

section shall control and  supersede  every other  provision of all existing and
future  agreements  between each such lender and each such 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 the 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 the lender may have in
the future to change the method of determining the Maximum Rate.

         Section 17. Treatment of 7-7. The parties hereby  acknowledge and agree
that 7-7, Inc., an Arkansas corporation ("7-7"), is a subsidiary of Consolidated
and is a party to various of the Security Documents. Although not a signatory to
this Agreement,  references in this Agreement to "Subsidiary" shall include 7-7,
and  nothing  in  this  Section  17  may  be  construed  as a  waiver  or  other
relinquishment  of rights by APS under any  Security  Document to which 7-7 is a
party.

         Section 18.  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 

                                       29

      7.2  Secured Party's Remedies. Upon the occurrence of an Event of Default:

immediately due and may enforce payment and performance of the same and exercise
any rights under the Texas UCC,  rights and remedies of Secured Party under this
Agreement, or otherwise.

                  (b) Secured  Party may, at Secured  Party's  option and at the
expense of Debtor,  either in Secured Party's own right or in the name of Debtor
and in the same manner and to the same extent that Debtor  might  reasonably  so
act  if  this  Agreement  had  not  been  made:  (i) do  all  things  requisite,
convenient,  or  necessary  to enforce the  performance  and  observance  of all


                                       25
<PAGE>

rights,  remedies and privileges of Debtor arising from the  Collateral,  or any
part thereof,  including without limitation compromising,  waiving, excusing, or
in any manner releasing or discharging any obligation of any party to or arising
from the Collateral;  (ii) take possession of the books, papers,  chattel paper,
documents of title, and accounts of Debtor,  wherever  located,  relating to the
Collateral; (iii) sue or otherwise collect and receive money attributable to the
Collateral;  and (iv) exercise any other lawfully  available powers or remedies,
and do all other things  which  Secured  Party deems  requisite,  convenient  or
necessary  or which the  Secured  Party  deems  proper to protect  the  Security
Interest.

                  (b) Secured Party may foreclose  this  Agreement in the manner
now or  hereafter  provided  or  permitted  by law and may upon such  reasonable
notification  prior thereto as may be required by applicable  law (Debtor hereby
agreeing  that ten  days'  notice is  commercially  reasonable),  sell,  assign,
transfer,  or otherwise  dispose of the Collateral at public or private sale, in
whole  or in  part,  and  Secured  Party  may,  in its own  name or as  Debtor's
attorney-in-fact  effectively  assign and transfer the  Collateral,  or any part
thereof,   absolutely,  and  execute  and  deliver  all  necessary  assignments,
conveyances,  bills of sale, and other  instruments with power to substitute one
or more persons or  corporations  with like power.  Any such  foreclosure  sale,
assignment,  transfer,  or other  disposition  shall, to the extent permitted by
law,  be a  perpetual  bar,  both at law and in equity,  against  Debtor and all
persons and corporations  lawfully  claiming by or through or under Debtor.  Any
such foreclosure sale may be adjourned from time to time. Upon any sale, Secured
Party may bid for and purchase the  Collateral,  or any part  thereof,  and upon
compliance with the terms of sale may hold,  retain,  possess and dispose of the
Collateral, in its absolute right 

                                       26
<PAGE>

without further accountability.  Secured Party
shall have the right to be  credited  on the  amount of its bid a  corresponding
amount of the Obligations as of the date of such sale.

                  (c) 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.

                  (d)  Not  in  limitation  of  any  other   provision  of  this
Agreement,  Secured  Party shall have all rights and remedies of a secured party
under the Texas UCC.

         7.3  Application  of Proceeds.  Secured Party may apply the proceeds of
any foreclosure  sale hereunder or from any other  permitted  disposition of the
Collateral  or any part  thereof as  follows:  (a) first,  to the payment of all
reasonable  costs and expenses of any foreclosure  and collection  hereunder and
all proceedings in connection  therewith,  including reasonable attorneys' fees;
(b) then, to the  reimbursement of Secured Party for all  disbursements  made by
Secured Party for taxes,  assessments or liens superior to the Security Interest
and  which  Secured  Party  shall  deem  expedient  to  pay;  (c)  then,  to the
reimbursement of Secured Party of any other  disbursements made by Secured Party
in accordance with the terms hereof or any of the Original Security Documents or
New Security Documents;  (d) then, to or among the amounts of fees, interest and


                                       27
<PAGE>

principal then owing and unpaid in respect of the Obligations,  in such priority
as Secured Party may determine in its discretion;  and (e) the remainder of such
proceeds,  if  any,  shall  be  paid  to  Debtor.  If  such  proceeds  shall  be
insufficient to discharge the entire  Obligations,  Secured Party shall have any
other  available legal recourse  against Debtor and all other persons  obligated
under, or for the performance of, the Note, the Original Security Documents, the
New Security Documents, this Agreement, and any other documents,  agreements, or
instruments executed in connection therewith, for the deficiency,  together with
interest thereon at the maximum non-usurious rate per annum.

         7.4  Enforcement  of  Obligations.  Nothing in this Agreement or in any
other agreement shall affect or impair the  unconditional  and absolute right of
the Secured Party to enforce the  Obligations  as and when the same shall become
due in  accordance  with the  terms of the  Note or  other  governing  document,
agreement, or instrument.

         7.5 Voting Rights.  Upon the occurrence of an Event of Default,  Debtor
will not  exercise  any voting  rights  with  respect to  securities  pledged as
Collateral.  Debtor  hereby  irrevocably  appoints  Secured  Party  as  Debtor's
attorney-in-fact  (such power of attorney  being  coupled with an interest)  and
proxy to exercise any voting rights with respect to Debtor's  securities pledged
as Collateral upon the occurrence of an Event of Default.

pertaining thereto.

and stead of Debtor and in the name of Debtor, Secured Party or otherwise,  from
time to time on Secured  Party's  discretion and upon the occurrence of an Event
of Default, to take any action and to execute any instrument which Secured Party

including without  limitation:  (a) to ask, demand,  collect,  sue for, recover,
compound, receive and give acquittance and receipts for moneys due and to become

any action or institute any proceeding which Secured Party may deem necessary or

         8.3  Performance  by Secured  Party.  If Debtor  fails to  perform  any
agreement  contained  herein,  Secured  Party may itself  perform,  or cause the
performance  of, such  agreement,  and the reasonable  expenses of Secured Party
incurred in connection  therewith  shall be payable by Debtor under Section 8.8.
In no  event,  however,  shall  Secured  Party  have any  obligation  or  duties
whatsoever to perform any covenant or agreement of Debtor contained herein,  and
any such performance by Secured Party shall be wholly discretionary with Secured
Party.

         8.4 Duties of Secured  Party.  The powers  conferred upon Secured Party
hereunder  are solely to protect its  interest in the  Collateral  and shall not
impose any duty upon it to exercise any such powers. Except for the safe custody
of any  Collateral  in its  possession  and the  accounting  for money  actually
received by it hereunder,  Secured Party shall have no duty as to any Collateral
or as to the taking of any  necessary  steps to preserve  rights  against  prior
parties or any other rights  pertaining to any Collateral.  Without limiting the
generality of the foregoing,  Secured Party shall not have any obligation,  duty
or  responsibility  to do any of the  following:  (a) ascertain any  maturities,
calls,  conversions,  exchanges,  offers, tenders or similar matters relating to
the  Collateral or informing  Debtor with respect to any such matters;  (b) fix,
preserve  or  exercise  any  right,  privilege  or option  (whether  conversion,
redemption or otherwise) with respect to the Collateral; (c) collect any amounts
payable  in  respect  of the  Collateral;  (d)  sell all or any  portion  of the
Collateral to avoid market loss; (e) sell all or any portion of the  Collateral;
or (f) hold the Collateral for or on behalf of any party other than Debtor.

         8.5 No  Liability  of Secured  Party.  Neither the  acceptance  of this
Agreement by Secured Party,  nor the exercise of any rights hereunder by Secured
Party,  shall be construed in any way 

                                       30
<PAGE>

as an  assumption  by Secured Party of any
obligations,  responsibilities,  or duties of Debtor arising in connection  with
the  Collateral  assigned  hereunder  or  otherwise  bind  Secured  Party to the
performance of any  obligations  respecting the  Collateral,  it being expressly
understood  that Secured  Party shall not be obligated to perform,  observe,  or
discharge  any  obligation,  responsibility,  duty,  or  liability  of Debtor in
respect of any of the Collateral,  including without limitation  appearing in or
defending any action, expending any money or incurring any expense in connection
therewith.

         8.6 Right of Secured Party to Defend Action Affecting Security. Secured
Party  may,  at the  expense  of  Debtor,  appear in and  defend  any  action or
proceeding at law or in equity  purporting to affect  Secured  Party's  Security
Interest under this Agreement.

         8.7 Right of  Secured  Party to Prevent  or Remedy  Default.  If Debtor
shall fail to perform any of the covenants,  conditions and agreements  required
to be performed and observed by Debtor under the Note, or any other  instruments
secured  hereby,  or in respect of the  Collateral  (subject  to any  applicable
default cure  period),  Secured Party (a) may but shall not be obligated to take
any action  Secured Party deems  necessary or desirable to prevent or remedy any
such default by Debtor or otherwise  to protect the Security  Interest,  and (b)
shall have the absolute and immediate right to take possession of the Collateral
or any part  thereof  (to the  extent  Secured  Party has not  previously  taken
possession)  to such  extent  and as often  as the  Secured  Party,  in its sole
discretion, deems necessary or desirable in order to prevent or to cure any such
default by Debtor,  or  otherwise  to protect the  security  of this  Agreement.
Secured Party may advance or expend such sums of money for the account of Debtor
as Secured Party in its sole discretion deems necessary for any such purpose.

                                       31

         8.8 Secured Party's Expenses. All reasonable advances, costs, expenses,
charges and attorneys' fees which Secured Party may make, pay or incur under any
provision  of this  Agreement  for the  protection  of its  security  or for the
enforcement  of any of  its  rights  hereunder,  or in  foreclosure  proceedings
commenced and subsequently  abandoned,  or in any dispute or litigation in which
Secured  Party or the holder of any of the  Obligations  may become  involved by
reason of or arising out of the Note, or the  Collateral  shall be a part of the
Obligations and shall be paid by Debtor to Secured Party, upon demand, and shall
bear interest until paid at the rate  otherwise  chargeable on the Note, but not
to exceed the maximum rate of interest  permitted by  applicable  law,  from the
date of such payment until repaid by Debtor.

         8.9. Convertible  Collateral.  Secured Party may present for conversion
any  Collateral  which is  convertible  into any other  instrument or investment
security or a  combination  thereof with cash,  but Secured Party shall not have
any duty to present for conversion any Collateral  unless it shall have received
from Debtor  detailed  written  instructions to that effect at a time reasonably
far in advance of the final conversion date to make such conversion possible.

         8.10 Secured Party's Right of Set-Off.  Upon the happening of any event
entitling  Secured  Party to pursue any remedy  provided  herein,  or if Secured
Party shall be served with garnishment process in which Debtor shall be named as
defendant,  whether or not Debtor  shall be in  default  hereunder  at the time,
Secured Party may, but shall not be required to, set-off any indebtedness  owing
by  Secured  Party  to  Debtor  against  any of the  Obligations  without  first


                                       32
<PAGE>

resorting to the security hereunder and without prejudice to any other rights or
remedies of Secured Party or its Security Interest.

         8.11 Remedies.  No right or remedy herein  reserved to Secured Party is
intended to be exclusive  of any other right or remedy,  but each and every such
remedy shall be cumulative,  not in lieu of, but in addition to any other rights
or remedies given under this Agreement and all other security documents. Any and
all of Secured  Party's  rights and remedies may be exercised  from time to time
and as often as such exercise as deemed necessary or desirable by Secured Party.

         8.12 Debtor's Waivers.  Debtor waives notice of the creation,  advance,
increase,  existence,  extension,  or  renewal  of, and of any  indulgence  with
respect to, the  Obligations;  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  Obligations
outstanding  at any time,  notice of any change in  financial  condition  of any
person liable for the  Obligations  or any part thereof,  notice of any Event of
Default,  and all other  notices  respecting  the  Obligations;  and agrees that
maturity of the Obligations  and any part thereof may be accelerated,  extended,
or renewed one or more times by Secured Party in its discretion,  without notice
to Debtor.

         8.13 Other Parties and Other Collateral.  No renewal or extension of or
any other  indulgence  with respect to the  Obligations or any part thereof,  no
release  of any  security,  no  release  of any  person  (including  any  maker,
endorser,  guarantor,  or  surety)  liable  on  the  Obligations,  no  delay  in
enforcement  of payment,  and no delay or admission or lack of diligence or care


                                       33
<PAGE>

in exercising any right or power with respect to the Obligations 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
Obligations,  before  foreclosing  upon the Collateral for the purpose of paying
the  Obligations.  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
Obligations any such other security or proceeds thereof.

                               DEBTOR'S COVENANTS

         Debtor covenants and agrees that:

         4.1  Indebtedness  and This  Agreement.  Debtor shall pay, or cause the
payment of, the  Indebtedness,  and any  indebtedness  secured by the  Permitted
Liens,  in  accordance  with its  terms and shall  promptly  perform  all of its
agreements  herein and in any other  agreements  between it and Secured Party or
between it and the holder of any Permitted Liens.

         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 except those for taxes not
yet due, the Security  Interest and the Permitted Liens.  Debtor shall not allow
any of the Permitted Liens to secure any indebtedness or obligations  other than
the specific  indebtedness  or obligations  outstanding,  and only to the extent
outstanding,  on the date this  Agreement  is  entered  into that are  expressly
secured by the applicable Permitted Liens as of such date. Debtor will not incur
or permit any increase in any  indebtedness or obligation  secured by any of the
Permitted Liens and will not enter into,  consent to, grant,  agree to or permit
any amendment  modification  or waiver of any right of Debtor or of any security
agreement contract,  understanding or other agreement of any kind which creates,
grants or otherwise gives risk to any of the Permitted Liens.


                                       11
<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  simultaneously  with any notice of
cancellation  or other  termination  being given to Debtor,  and in any event at
least 10 days prior to cancellation or other termination. 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.

         4.5 Secured  Party's  Costs.  Debtor  shall pay all costs  necessary to
obtain, preserve,  perfect,  defend, and enforce the 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


                                       12
<PAGE>

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  requested by Secured Party;  (ii) allow Secured Party
to inspect the Collateral,  at any 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  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

or instruments  (including without limitation any financing  statements or deeds
of trust) furnished by Secured Party, and take such further action,  at Debtor's
sole cost and expense,  which are  necessary in the 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.


                                       13
<PAGE>

         4.8 Parties Liable on Collateral. Debtor will preserve the liability of
all obligors on any  Collateral  and will  preserve the priority of all security
therefor.  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.  At any time,  whether
Debtor is or is not in 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.  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 


                                       14
<PAGE>

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


                                       15
<PAGE>

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 pater.

         4.13  Disposition  of  Collateral.  Debtor  will  not  sell,  transfer,
mortgage,  or otherwise  encumber any  Collateral or impair the value thereof in
any manner without Secured Party's prior written consent, which Secured Party is
under  no  obligation  whatsoever  to  give,  including  without  limitation  by
purchase, lease, barter, trade, payment deferral, or the creation, assumption or
guarantee of indebtedness  or other lending of credit;  provided,  however,  the
foregoing  shall not be applicable to Debtor with respect to (i) inventory sold,
leased, manufactured, processed, or consumed in the ordinary course of business,
and (ii)  unsecured  open account trade debts to unrelated  parties  incurred by
Debtor in the ordinary  course of business.  Secured  Party's written consent to
any sale,  mortgage,  transfer,  or  encumbrance  shall not be construed to be a
waiver of this provision with respect to any subsequent proposed sale, mortgage,
transfer,  or  encumbrance.  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.

         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.


                                       16

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 (as defined
in Section 6.1 hereof).

         4.17 Use and Removal of Collateral.  Debtor will not use the Collateral
illegally nor, except for Collateral of nominal value,  permit the Collateral to
be affixed to real or personal  property  without the prior  written  consent of
Secured  Party.  Debtor will not permit any of the Collateral to be removed from
the locations specified herein 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


                                       17
<PAGE>

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
without Secured Party's prior written  consent,  which shall not be unreasonably
withheld.  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 

                                       18
<PAGE>

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 and deliver such certificates
to Secured Party.

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

         4.24 Debtor's Waivers.  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

Default,  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.

                                    ARTICLE V
                       RIGHTS AND POWERS OF SECURED PARTY

         Secured Party, after 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;
require Debtor to give possession or control of any Collateral to Secured Party;
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;  take control of proceeds;
release  Collateral in its  possession to any Debtor  temporarily  or otherwise;
require additional  collateral;  reject as unsatisfactory any property hereafter


                                       20
<PAGE>

offered by Debtor as Collateral;  set standards from time to time to govern what
may be used as  after-acquired  collateral;  designate,  from  time to  time,  a
certain  percent  of the  Collateral  as the loan  value and  require  Debtor to
maintain  the  Indebtedness  at or below  such  figure;  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;  at any
time  transfer any of the  Collateral  or evidence  thereof into its own name of
that of its nominee; and 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(d) above.

                  (f) belief by Secured  Party that the  prospect  of payment of
         the Indebtedness or performance of this Agreement is impaired;

                  (g)  dissolution,  merger,  or  consolidation,  termination of

         partnership  of which Debtor is a partner,  or by or against any person

                  (h)      levy  on,  seizure,  or  attachment  of any  property
         of  Debtor  or  any  of  Debtor's subsidiaries;

                  (i) a  judgment  against  Debtor in  excess of $1,000  becomes

                  (j) any  liability or  agreement  of third  parties to or with

<PAGE>

                  (k) any breach or default by Debtor under any agreement giving
         rise  to any of the  Permitted  Liens  or  under  any  indebtedness  or
         obligation  secured thereby,  or any action by any holder of any of the
         Permitted  Liens is taken or  instituted  to enforce the rights of such
         holder with respect to any such Permitted Liens.

         6.2 Remedies of Secured  Party Upon  Default.  When an Event of Default
occurs,  and at any time thereafter,  Secured Party without notice or demand 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. Unless the Collateral
is  perishable  or  threatens  to  decline  speedily  in  value  or is of a type
customarily  sold  on a  recognized  market,  Secured  Party  will  give  Debtor
reasonable  notice of the time and place of any  public  sale  thereof or of the
time after which any private sale or other intended disposition thereof is to be
made. Expenses of retaking,  holding,  preparing for sale, selling,  leasing, or
the like shall 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 

                                       24
<PAGE>

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;  No Liability  of Secured  Party.  Secured  Party's
rights  under  this  Agreement  and the  Security  Interest  shall  inure to the
benefits of its successors and assigns.  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. Debtor may not assign this Agreement or any of its rights or obligations
hereunder  without the express  prior  written  consent of Secured Party in each
instance.  Neither the acceptance of this  Agreement by Secured  Party,  nor the
exercise of any rights hereunder by Secured Party, shall be construed in any way
as an  assumption  by Secured  Party of any  obligations,  responsibilities,  or
duties of Debtor arising in connection with the Collateral assigned hereunder or


                                       25
<PAGE>

otherwise bind Secured Party to the  performance of any  obligations  respecting
the Collateral,  it being  expressly  understood that Secured Party shall not be
obligated to perform,  observe,  or discharge  any  obligation,  responsibility,
duty,  or  liability  of Debtor in respect of any of the  Collateral,  including
without limitation appearing in or defending any action,  expending any money or
incurring any expense in connection therewith.

         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.

the  Texas  UCC  apply to words  and  phrases  in this  Agreement;  if Texas UCC
definitions conflict, Chapter 9 definitions apply.

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
Debtor's  address  shown  above.  The  terms of this  Agreement  shall be deemed
commercially reasonable within the meaning of the Texas UCC.

         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 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.

("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

                               DEBTOR'S COVENANTS

         Debtor covenants and agrees that:

         4.1  Indebtedness  and This  Agreement.  Debtor shall pay, or cause the
payment of, the  Indebtedness,  and any  indebtedness  secured by the  Permitted
Liens,  in  accordance  with its  terms and shall  promptly  perform  all of its
agreements  herein and in any other  agreements  between it and Secured Party or
between it and the holder of any Permitted Liens.

         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 except those for taxes not
yet due, the Security  Interest and the Permitted Liens.  Debtor shall not allow
any of the Permitted Liens to secure any indebtedness or obligations  other than
the specific  indebtedness  or obligations  outstanding,  and only to the extent
outstanding,  on the date this  Agreement  is  entered  into that are  expressly
secured by the applicable Permitted Liens as of such date. Debtor will not incur
or permit any increase in any  indebtedness or obligation  secured by any of the
Permitted Liens and will not enter into,  consent to, grant,  agree to or permit
any amendment  modification  or waiver of any right of Debtor or of any security
agreement contract,  understanding or other agreement of any kind which creates,
grants or otherwise gives risk to any of the Permitted Liens.


                                       11
<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  simultaneously  with any notice of
cancellation  or other  termination  being given to Debtor,  and in any event at
least 10 days prior to cancellation or other termination. 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.

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


                                       12
<PAGE>

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  requested by Secured Party;  (ii) allow Secured Party
to inspect the Collateral,  at any time and wherever located, and to inspect and
copy,  or furnish  Secured  Party with  copies of, all  records  relating to the

or instruments  (including without limitation any financing  statements or deeds
of trust) furnished by Secured Party, and take such further action,  at Debtor's
sole cost and expense,  which are  necessary in the 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.


                                       13
<PAGE>

         4.8 Parties Liable on Collateral. Debtor will preserve the liability of
all obligors on any  Collateral  and will  preserve the priority of all security
therefor.  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.  At any time,  whether
Debtor is or is not in 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.  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

                                       14
<PAGE>

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 

                                       15
<PAGE>

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 pater.

         4.13  Disposition  of  Collateral.  Debtor  will  not  sell,  transfer,
mortgage,  or otherwise  encumber any  Collateral or impair the value thereof in
any manner without Secured Party's prior written consent, which Secured Party is
under  no  obligation  whatsoever  to  give,  including  without  limitation  by
purchase, lease, barter, trade, payment deferral, or the creation, assumption or
guarantee of indebtedness  or other lending of credit;  provided,  however,  the
foregoing  shall not be applicable to Debtor with respect to (i) inventory sold,
leased, manufactured, processed, or consumed in the ordinary course of business,
and (ii)  unsecured  open account trade debts to unrelated  parties  incurred by
Debtor in the ordinary  course of business.  Secured  Party's written consent to
any sale,  mortgage,  transfer,  or  encumbrance  shall not be construed to be a
waiver of this provision with respect to any subsequent proposed sale, mortgage,
transfer,  or  encumbrance.  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.

         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.

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 (as defined
in Section 6.1 hereof).

         4.17 Use and Removal of Collateral.  Debtor will not use the Collateral
illegally nor, except for Collateral of nominal value,  permit the Collateral to
be affixed to real or personal  property  without the prior  written  consent of
Secured  Party.  Debtor will not permit any of the Collateral to be removed from
the locations specified herein 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


                                       17
<PAGE>

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
without Secured Party's prior written  consent,  which shall not be unreasonably
withheld.  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 

                                       18
<PAGE>

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 and deliver such certificates
to Secured Party.

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

         4.24 Debtor's Waivers.  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

or renewed one or more times by Secured Party in its discretion,  without notice
to Debtor.

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.

                       RIGHTS AND POWERS OF SECURED PARTY

         Secured Party, after 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;
require Debtor to give possession or control of any Collateral to Secured Party;
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;  take control of proceeds;
release  Collateral in its  possession to any Debtor  temporarily  or otherwise;
require additional  collateral;  reject as unsatisfactory any property hereafter


                                       20

offered by Debtor as Collateral;  set standards from time to time to govern what
may be used as  after-acquired  collateral;  designate,  from  time to  time,  a
certain  percent  of the  Collateral  as the loan  value and  require  Debtor to
maintain  the  Indebtedness  at or below  such  figure;  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;  at any
time  transfer any of the  Collateral  or evidence  thereof into its own name of
that of its nominee; and 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(d) above.

                  (f) belief by Secured  Party that the  prospect  of payment of
         the Indebtedness or performance of this Agreement is impaired;

                  (g)  dissolution,  merger,  or  consolidation,  termination of

                  (i) a  judgment  against  Debtor in  excess of $1,000  becomes

         days;

                  (j) any  liability or  agreement  of third  parties to or with

<PAGE>

                  (k) any breach or default by Debtor under any agreement giving
         rise  to any of the  Permitted  Liens  or  under  any  indebtedness  or
         obligation  secured thereby,  or any action by any holder of any of the
         Permitted  Liens is taken or  instituted  to enforce the rights of such
         holder with respect to any such Permitted Liens.

         6.2 Remedies of Secured  Party Upon  Default.  When an Event of Default
occurs,  and at any time thereafter,  Secured Party without notice or demand 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. Unless the Collateral
is  perishable  or  threatens  to  decline  speedily  in  value  or is of a type
customarily  sold  on a  recognized  market,  Secured  Party  will  give  Debtor
reasonable  notice of the time and place of any  public  sale  thereof or of the
time after which any private sale or other intended disposition thereof is to be
made. Expenses of retaking,  holding,  preparing for sale, selling,  leasing, or
the like shall 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 

                                       24
<PAGE>

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;  No Liability  of Secured  Party.  Secured  Party's
rights  under  this  Agreement  and the  Security  Interest  shall  inure to the
benefits of its successors and assigns.  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. Debtor may not assign this Agreement or any of its rights or obligations
hereunder  without the express  prior  written  consent of Secured Party in each
instance.  Neither the acceptance of this  Agreement by Secured  Party,  nor the
exercise of any rights hereunder by Secured Party, shall be construed in any way
as an  assumption  by Secured  Party of any  obligations,  responsibilities,  or
duties of Debtor arising in connection with the Collateral assigned hereunder or


                                       25
<PAGE>

otherwise bind Secured Party to the  performance of any  obligations  respecting
the Collateral,  it being  expressly  understood that Secured Party shall not be
obligated to perform,  observe,  or discharge  any  obligation,  responsibility,
duty,  or  liability  of Debtor in respect of any of the  Collateral,  including
without limitation appearing in or defending any action,  expending any money or
incurring any expense in connection therewith.

         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.

the  Texas  UCC  apply to words  and  phrases  in this  Agreement;  if Texas UCC
definitions conflict, Chapter 9 definitions apply.

         7.5  Notice;  Terms  Commercially  Reasonable.  Notice  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
Debtor's  address  shown  above.  The  terms of this  Agreement  shall be deemed
commercially reasonable within the meaning of the Texas UCC.

         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 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.

("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.

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

                               DEBTOR'S COVENANTS

         Debtor covenants and agrees that:

         4.1  Indebtedness  and This  Agreement.  Debtor shall pay, or cause the
payment of, the  Indebtedness,  and any  indebtedness  secured by the  Permitted
Liens,  in  accordance  with its  terms and shall  promptly  perform  all of its
agreements  herein and in any other  agreements  between it and Secured Party or
between it and the holder of any Permitted Liens.

         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 except those for taxes not
yet due, the Security  Interest and the Permitted Liens.  Debtor shall not allow
any of the Permitted Liens to secure any indebtedness or obligations  other than
the specific  indebtedness  or obligations  outstanding,  and only to the extent
outstanding,  on the date this  Agreement  is  entered  into that are  expressly
secured by the applicable Permitted Liens as of such date. Debtor will not incur
or permit any increase in any  indebtedness or obligation  secured by any of the
Permitted Liens and will not enter into,  consent to, grant,  agree to or permit
any amendment  modification  or waiver of any right of Debtor or of any security
agreement contract,  understanding or other agreement of any kind which creates,
grants or otherwise gives risk to any of the Permitted Liens.


                                       11
<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  simultaneously  with any notice of
cancellation  or other  termination  being given to Debtor,  and in any event at
least 10 days prior to cancellation or other termination. 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.

         4.5 Secured  Party's  Costs.  Debtor  shall pay all costs  necessary to

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


                                       12
<PAGE>

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  requested by Secured Party;  (ii) allow Secured Party
to inspect the Collateral,  at any 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  request  to  identify  inventory,   accounts,  and  general

or instruments  (including without limitation any financing  statements or deeds
of trust) furnished by Secured Party, and take such further action,  at Debtor's
sole cost and expense,  which are  necessary in the 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.


                                       13
<PAGE>

         4.8 Parties Liable on Collateral. Debtor will preserve the liability of
all obligors on any  Collateral  and will  preserve the priority of all security
therefor.  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.  At any time,  whether
Debtor is or is not in 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.  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

                                       14
<PAGE>

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 

                                       15
<PAGE>

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 pater.

         4.13  Disposition  of  Collateral.  Debtor  will  not  sell,  transfer,
mortgage,  or otherwise  encumber any  Collateral or impair the value thereof in
any manner without Secured Party's prior written consent, which Secured Party is
under  no  obligation  whatsoever  to  give,  including  without  limitation  by
purchase, lease, barter, trade, payment deferral, or the creation, assumption or
guarantee of indebtedness  or other lending of credit;  provided,  however,  the
foregoing  shall not be applicable to Debtor with respect to (i) inventory sold,
leased, manufactured, processed, or consumed in the ordinary course of business,
and (ii)  unsecured  open account trade debts to unrelated  parties  incurred by
Debtor in the ordinary  course of business.  Secured  Party's written consent to
any sale,  mortgage,  transfer,  or  encumbrance  shall not be construed to be a
waiver of this provision with respect to any subsequent proposed sale, mortgage,
transfer,  or  encumbrance.  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.

         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.

                                       16

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 (as defined
in Section 6.1 hereof).

         4.17 Use and Removal of Collateral.  Debtor will not use the Collateral
illegally nor, except for Collateral of nominal value,  permit the Collateral to
be affixed to real or personal  property  without the prior  written  consent of
Secured  Party.  Debtor will not permit any of the Collateral to be removed from
the locations specified herein 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


                                       17
<PAGE>

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
without Secured Party's prior written  consent,  which shall not be unreasonably
withheld.  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 

                                       18
<PAGE>

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 and deliver such certificates
to Secured Party.

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

         4.24 Debtor's Waivers.  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

Default,  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.

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.

                       RIGHTS AND POWERS OF SECURED PARTY

         Secured Party, after 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;
require Debtor to give possession or control of any Collateral to Secured Party;
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;  take control of proceeds;
release  Collateral in its  possession to any Debtor  temporarily  or otherwise;
require additional  collateral;  reject as unsatisfactory any property hereafter


                                       20

offered by Debtor as Collateral;  set standards from time to time to govern what
may be used as  after-acquired  collateral;  designate,  from  time to  time,  a
certain  percent  of the  Collateral  as the loan  value and  require  Debtor to
maintain  the  Indebtedness  at or below  such  figure;  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;  at any
time  transfer any of the  Collateral  or evidence  thereof into its own name of
that of its nominee; and 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(d) above.

                  (f) belief by Secured  Party that the  prospect  of payment of
         the Indebtedness or performance of this Agreement is impaired;

                  (g)  dissolution,  merger,  or  consolidation,  termination of

         Collateral;

                  (h)      levy on,  seizure,  or  attachment of any property of
         Debtor,  Consolidated,  or any of Consolidated's subsidiaries;

                  (i) a  judgment  against  Debtor in  excess of $1,000  becomes

         days;

                  (j) any  liability or  agreement  of third  parties to or with

<PAGE>

                  (k) any breach or default by Debtor under any agreement giving
         rise  to any of the  Permitted  Liens  or  under  any  indebtedness  or
         obligation  secured thereby,  or any action by any holder of any of the
         Permitted  Liens is taken or  instituted  to enforce the rights of such
         holder with respect to any such Permitted Liens.

         6.2 Remedies of Secured  Party Upon  Default.  When an Event of Default
occurs,  and at any time thereafter,  Secured Party without notice or demand 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. Unless the Collateral
is  perishable  or  threatens  to  decline  speedily  in  value  or is of a type
customarily  sold  on a  recognized  market,  Secured  Party  will  give  Debtor
reasonable  notice of the time and place of any  public  sale  thereof or of the
time after which any private sale or other intended disposition thereof is to be
made. Expenses of retaking,  holding,  preparing for sale, selling,  leasing, or
the like shall 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 

                                       24
<PAGE>

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;  No Liability  of Secured  Party.  Secured  Party's
rights  under  this  Agreement  and the  Security  Interest  shall  inure to the
benefits of its successors and assigns.  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. Debtor may not assign this Agreement or any of its rights or obligations
hereunder  without the express  prior  written  consent of Secured Party in each
instance.  Neither the acceptance of this  Agreement by Secured  Party,  nor the
exercise of any rights hereunder by Secured Party, shall be construed in any way
as an  assumption  by Secured  Party of any  obligations,  responsibilities,  or
duties of Debtor arising in connection with the Collateral assigned hereunder or


                                       25
<PAGE>

otherwise bind Secured Party to the  performance of any  obligations  respecting
the Collateral,  it being  expressly  understood that Secured Party shall not be
obligated to perform,  observe,  or discharge  any  obligation,  responsibility,
duty,  or  liability  of Debtor in respect of any of the  Collateral,  including
without limitation appearing in or defending any action,  expending any money or
incurring any expense in connection therewith.

         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.

the  Texas  UCC  apply to words  and  phrases  in this  Agreement;  if Texas UCC
definitions conflict, Chapter 9 definitions apply.

         7.5  Notice;  Terms  Commercially  Reasonable.  Notice  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
Debtor's  address  shown  above.  The  terms of this  Agreement  shall be deemed
commercially reasonable within the meaning of the Texas UCC.

         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 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.

("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.

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

                               DEBTOR'S COVENANTS

         Debtor covenants and agrees that:

         4.1  Indebtedness  and This  Agreement.  Debtor shall pay, or cause the
payment of, the  Indebtedness,  and any  indebtedness  secured by the  Permitted
Liens,  in  accordance  with its  terms and shall  promptly  perform  all of its
agreements  herein and in any other  agreements  between it and Secured Party or

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

yet due, the Security  Interest and the Permitted Liens.  Debtor shall not allow
any of the Permitted Liens to secure any indebtedness or obligations  other than
the specific  indebtedness  or obligations  outstanding,  and only to the extent
outstanding,  on the date this  Agreement  is  entered  into that are  expressly
secured by the applicable Permitted Liens as of such date. Debtor will not incur
or permit any increase in any  indebtedness or obligation  secured by any of the
Permitted Liens and will not enter into,  consent to, grant,  agree to or permit
any amendment  modification  or waiver of any right of Debtor or of any security
agreement contract,  understanding or other agreement of any kind which creates,
grants or otherwise gives risk to any of the Permitted Liens.


                                       11
<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  simultaneously  with any notice of
cancellation  or other  termination  being given to Debtor,  and in any event at
least 10 days prior to cancellation or other termination. 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.

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


                                       12
<PAGE>

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  requested by Secured Party;  (ii) allow Secured Party
to inspect the Collateral,  at any time and wherever located, and to inspect and

or instruments  (including without limitation any financing  statements or deeds
of trust) furnished by Secured Party, and take such further action,  at Debtor's
sole cost and expense,  which are  necessary in the 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.

<PAGE>

         4.8 Parties Liable on Collateral. Debtor will preserve the liability of
all obligors on any  Collateral  and will  preserve the priority of all security
therefor.  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.  At any time,  whether
Debtor is or is not in 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.  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

                                       14
<PAGE>

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 

                                       15
<PAGE>

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 pater.

         4.13  Disposition  of  Collateral.  Debtor  will  not  sell,  transfer,
mortgage,  or otherwise  encumber any  Collateral or impair the value thereof in
any manner without Secured Party's prior written consent, which Secured Party is
under  no  obligation  whatsoever  to  give,  including  without  limitation  by
purchase, lease, barter, trade, payment deferral, or the creation, assumption or
guarantee of indebtedness  or other lending of credit;  provided,  however,  the
foregoing  shall not be applicable to Debtor with respect to (i) inventory sold,
leased, manufactured, processed, or consumed in the ordinary course of business,
and (ii)  unsecured  open account trade debts to unrelated  parties  incurred by
Debtor in the ordinary  course of business.  Secured  Party's written consent to
any sale,  mortgage,  transfer,  or  encumbrance  shall not be construed to be a
waiver of this provision with respect to any subsequent proposed sale, mortgage,
transfer,  or  encumbrance.  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.

         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.

                                       16

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 (as defined
in Section 6.1 hereof).

         4.17 Use and Removal of Collateral.  Debtor will not use the Collateral
illegally nor, except for Collateral of nominal value,  permit the Collateral to
be affixed to real or personal  property  without the prior  written  consent of
Secured  Party.  Debtor will not permit any of the Collateral to be removed from
the locations specified herein 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


                                       17
<PAGE>

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
without Secured Party's prior written  consent,  which shall not be unreasonably
withheld.  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 

                                       18
<PAGE>

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 and deliver such certificates
to Secured Party.

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

         4.24 Debtor's Waivers.  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

or renewed one or more times by Secured Party in its discretion,  without notice
to Debtor.

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.

                       RIGHTS AND POWERS OF SECURED PARTY

         Secured Party, after 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;
require Debtor to give possession or control of any Collateral to Secured Party;
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;  take control of proceeds;
release  Collateral in its  possession to any Debtor  temporarily  or otherwise;
require additional  collateral;  reject as unsatisfactory any property hereafter


                                       20

offered by Debtor as Collateral;  set standards from time to time to govern what
may be used as  after-acquired  collateral;  designate,  from  time to  time,  a
certain  percent  of the  Collateral  as the loan  value and  require  Debtor to
maintain  the  Indebtedness  at or below  such  figure;  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;  at any
time  transfer any of the  Collateral  or evidence  thereof into its own name of
that of its nominee; and 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(d) above.

                                     DEFAULT

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

                  (a) default,  by Consolidated,  Debtor or any other subsidiary
         of Consolidated, in the timely payment of any part of the Note or other

         the  terms  and  conditions  herein,  in any of the  Original  Security
         Documents,  in any of  the  New  Security  Documents,  or in any  other

         respect when made or furnished;

                  (c)   acceleration   of  the   maturity  of  debt  of  Debtor,
         Consolidated,  or  any of  Consolidated's  subsidiaries  to  any  other
         person;

                  (d) substantial change in any fact warranted or represented in
         this  Agreement or in any other  agreement  between  Debtor and Secured
         Party or in any  statement,  schedule,  or other  writing  furnished in
         connection therewith;

                                       22
<PAGE>

                  (e)  sale,  loss,   theft,   destruction,   incurrence  of  an
         encumbrance upon, or transfer of any Collateral in violation hereof, or
         substantial damage to any Collateral;

                  (f) belief by Secured  Party that the  prospect  of payment of
         the Indebtedness or performance of this Agreement is impaired;

                  (g)  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  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;

                  (h)      levy on,  seizure,  or  attachment of any property of
         Debtor,  Consolidated,  or any of Consolidated's subsidiaries;

                  (i) a  judgment  against  Debtor in  excess of $1,000  becomes
         final and remains  unsatisfied  and unappealed for thirty (30) calendar
         days;

                  (j) any  liability or  agreement  of third  parties to or with
         Debtor on or relating to the Collateral  shall not be paid or performed
         in accordance with the terms thereof; or

                                       23
<PAGE>

                  (k) any breach or default by Debtor under any agreement giving
         rise  to any of the  Permitted  Liens  or  under  any  indebtedness  or
         obligation  secured thereby,  or any action by any holder of any of the
         Permitted  Liens is taken or  instituted  to enforce the rights of such
         holder with respect to any such Permitted Liens.

         6.2 Remedies of Secured  Party Upon  Default.  When an Event of Default
occurs,  and at any time thereafter,  Secured Party without notice or demand 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. Unless the Collateral
is  perishable  or  threatens  to  decline  speedily  in  value  or is of a type
customarily  sold  on a  recognized  market,  Secured  Party  will  give  Debtor
reasonable  notice of the time and place of any  public  sale  thereof or of the
time after which any private sale or other intended disposition thereof is to be
made. Expenses of retaking,  holding,  preparing for sale, selling,  leasing, or
the like shall 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 

                                       24
<PAGE>

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;  No Liability  of Secured  Party.  Secured  Party's
rights  under  this  Agreement  and the  Security  Interest  shall  inure to the
benefits of its successors and assigns.  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. Debtor may not assign this Agreement or any of its rights or obligations
hereunder  without the express  prior  written  consent of Secured Party in each
instance.  Neither the acceptance of this  Agreement by Secured  Party,  nor the
exercise of any rights hereunder by Secured Party, shall be construed in any way
as an  assumption  by Secured  Party of any  obligations,  responsibilities,  or
duties of Debtor arising in connection with the Collateral assigned hereunder or


                                       25
<PAGE>

otherwise bind Secured Party to the  performance of any  obligations  respecting
the Collateral,  it being  expressly  understood that Secured Party shall not be
obligated to perform,  observe,  or discharge  any  obligation,  responsibility,
duty,  or  liability  of Debtor in respect of any of the  Collateral,  including
without limitation appearing in or defending any action,  expending any money or
incurring any expense in connection therewith.

         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.


                                       26

         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;  Terms  Commercially  Reasonable.  Notice  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
Debtor's  address  shown  above.  The  terms of this  Agreement  shall be deemed
commercially reasonable within the meaning of the Texas UCC.

         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 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.


                                       27

         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 Uniform  Commercial Code as in effect in the State of Texas
("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.
