                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)
                                MARCH 31, 1996

NOTE 1 BASIS OF PRESENTATION:

The accompanying unaudited consolidated financial statements have been prepared
in accordance with generally accepted accounting principles for interim
financial information and with the instructions to Form 10-QSB.  Accordingly,
they do not include all of the information and footnotes required by generally
accepted accounting principles for complete financial statements.  In the
opinion of management, all adjustments (consisting only of those of a normal
recurring nature) considered necessary for a fair presentation have been
included.  Operating results for the three month period ended March 31, 1996 are
not necessarily indicative of the results that may be expected for the year
ending December 31, 1996.  For further information, refer to the consolidated
financial statements and footnotes thereto included in the Company's annual
report on Form 10-KSB for the year ended December 31, 1995.

The preparation of consolidated financial statements in accordance with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets, liabilities,
revenues and expenses, as well as the disclosures of contingent assets and
liabilities. Because of the inherent uncertainties in this process, actual
future results could differ from those expected at the reporting date.

Certain amounts in the March 31, 1995 consolidated statements of operations have
been reclassified to conform to the March 31, 1996 presentation, the most
significant of which is an allocation of a portion of the provision for doubtful
accounts to contractual allowances to more properly reflect revenue from
services rendered to personal injury claimants at the net amounts expected to be
collected upon claim adjudication.  The reclassification was based on improved
historical information and currently expected recovery rates.  In addition,
selected natural expense classifications have been presented to enhance industry
comparability.  None of these changes affected net income or loss.


NOTE 2 EARNINGS PER COMMON SHARE:

Primary and fully diluted earnings per common share is based upon the weighted
average number of shares of common stock outstanding and common stock
equivalents of dilutive stock options and warrants during the three month
periods, as follows:

Note 3  Subsequent Events:

In April, 1996, the Company issued a $2.5 million convertible subordinated note
to provide acquisition and working capital in support of the Company's planned
expansion.  At the Company's annual shareholders' meeting on May 9, 1996, over
two-thirds of the Company's shareholders approved the creation of 10,000,000
shares of preferred stock.  Immediately thereafter, the Company's board of
directors approved the issuance of 25,191 shares of the Company's Series A
Cumulative Convertible Preferred Stock in exchange for the $2.5 million
convertible subordinated note plus $19,178 in accrued interest thereon.  (The
Series A Cumulative Convertible Preferred Stock is described in the Company's
definitive proxy statement dated April 12, 1996.)

                             FINANCIAL INFORMATION

Item 2  Management's Discussion and Analysis of Financial Condition and Results
        of Operations.

RESULTS OF OPERATIONS:

Three months ended March 31, 1996 compared with three months ended March 31,
1995.

Revenues.

Revenues for the first quarter of 1996 increased by $472,289 or about 13%.  The
increase is mainly due to orthopedic practices added to an affiliated medical
group in 1995.  Revenues were also higher at the other Houston medical clinics,
the work hardening facilities, and mobile testing.  Revenues from the other
business units were flat or lower.  Changes in these revenues are generally due
to changes in the number of patient visits.

Compensation Costs and Medical Services.

Compensation costs and medical services increased $383,761 or 27.4%.  This
increase is due mainly to the addition of the orthopedic practices to an
affiliated medical group in 1995.

Other Direct Costs

Other direct costs in 1996 increased $87,218 or 10.8% over 1995, due primarily
to the addition of the orthopedic practices to an affiliated medical group in
1995.

Selling, General and Administrative Expenses.

Costs increased by $14,305 or less than 3%.  The difference is within the normal
range of cost fluctuations.  No single type of expense increased or decreased by
more than 4%.

Depreciation and Amortization.

The decrease in 1996 of $111,776 is due to the full depreciation and
amortization of certain assets in 1995.

Provision for Doubtful Accounts.

Expenses increased by $250,542, mainly because the allowance percentage for
orthopedic surgery cases billed to third-party payors is higher than the Company
has experienced in the past for third-party claims.  Generally, mandated
orthopedic reimbursement rates decline per individual patient as more surgical
procedures are performed.

                                       7

Loss on Sale of Subsidiary.

The Company recorded a loss on the sale of a wholly-owned subsidiary in March,
1996.  Proceeds from the sale were sufficient to retire the Company's
liabilities related to the subsidiary (see Liquidity and Capital Resources).

Minority Interest.

Minority interest in income decreased by $33,654, due to the Company's winding
down of all partnership interests.

Interest Expense.

Interest expense decreased by $9,919 or about 13%, due to the reduction of the
principal balances on various notes and capital lease obligations.


LIQUIDITY AND CAPITAL RESOURCES

The Company's working capital at March 31, 1996 was $3,016,516 as compared to
$2,654,842 at December 31, 1995, an improvement of $361,674.  This is mainly due
to (1) an increase in net accounts receivable of $246,590 due principally to
increased revenues from the orthopedic practices added to an affiliated medical
group in 1995, and (2) the paying down of the current portion of notes and
capital leases payable in the amount of $160,131.

Personal injury accounts receivable have decreased in 1996, decreasing their
percentage of net accounts receivable from 42% at December 31, 1995 to 40% at
March 31, 1996.  Although currently due, personal injury claims usually take
significantly longer to collect than claims billed to insurance carriers and
employers.  Net reimbursement for personal injury claims is generally equal to
or greater than the net reimbursement on other claims.

In March, 1996, the Company made the final scheduled payment on the Houston MRI.
Monthly obligations relating to the purchase of this MRI are expected to fall
from approximately $36,000 per month to less than $9,000 per month.  The Company
also disposed of a subsidiary in March, 1996.  In conjunction with this
disposition, the Company retired approximately $692,000 in notes payable, of
which, $243,586 was classified as a current liability at December 31, 1995.

On January 30, 1996, the Company amended its loan agreement and increased its
revolving line of credit from $1,000,000 to $2,000,000 with its primary
commercial bank.  The line of credit is secured by substantially all the assets
of the Company and its affiliated medical groups.  The revolving line of credit
requires the payment of a 1% annual fee.  Borrowings under the line bear
interest at prime + 1.25% and the line expires January 30, 1997.  Advances under
the line of credit are subject to a borrowing base formula under which the
Company presently has sufficient collateral to support the entire line
availability.   The Company also received a commitment to fund up to $500,000 in
equipment purchases through January 30, 1997, at 

                                       8

which time all amounts outstanding under the commitment will convert to either 
3- or 4- year term notes. The line of credit as well as other borrowings from
the Company's major lender are subject to the terms of a loan agreement which
include typical financial ratio covenants and various other provisions.

In April, 1996, the Company issued a $2.5 million convertible subordinated note
to provide acquisition and working capital in support of the Company's planned
expansion.  At the Company's annual shareholders' meeting on May 9, 1996, over
two-thirds of the Company's shareholders approved the creation of 10,000,000
shares of preferred stock.  Immediately thereafter, the Company's board of
directors approved the issuance of 25,191 shares of the Company's Series A
Cumulative Convertible Preferred Stock in exchange for the $2.5 million
convertible subordinated note plus $19,178 in accrued interest thereon.  (The
Series A Cumulative Convertible Preferred Stock is described in the Company's
definitive proxy statement dated April 12, 1996.)  The Company believes its 
existing credit facilities and cash provided by operations will be sufficient to
provide for the Company's existing operations for at least the next twelve
months. The Company has plans to expand its physician practice management
services through the acquisition of orthopedic and orthopedics-related medical
practice assets and through the acquisition or development of musculoskeletal
injury- and illness-related ancillary services required by these medical
practices. Depending upon the Company's experience in this expansion program,
additional sources of acquisition capital may be required.

Borrower: DRCA MEDICAL CORPORATION (TIN: 76-0203483)
          Three Riverway, Suite 1430
          Houston, TX 77056

Lender:   First Interstate Bank of Texas, N.A.

===============================================================================
Principal Amount: $2,000,000.00                         Initial Rate: 9.750%
Date of Note: January 30, 1996

PROMISE TO PAY. DRCA MEDICAL CORPORATION ("Borrower") promises to pay to First 
Interstate Bank of Texas, N.A. ("Lender"), or order, in lawful money of the 
United States of America, the principal amount of Two Million & 00/100 Dollars 
($2,000,000.00) or so much as may be outstanding, together with interest on the 
unpaid outstanding principal balance of each advance. Interest shall be 
calculated from the date of each advance until repayment of each advance or 
maturity, whichever occurs first.

CHOICE OF USURY CEILING AND INTEREST RATE. The interest rate on this Note has 
been implemented under the "Indicated Rate Ceiling" as referred to in Article 
5069-1.04(a)(1) V.T.C.S. The terms, including the rate, or index, formula, or
provision of law used to compute the rate on the Note, will be subject to
revision as to current and future balances, from time to time by notice from
Lender in compliance with Article 5069-1.04(i) V.T.C.S.

PAYMENT: Borrower will pay this loan in one payment of all outstanding 
principal plus all accrued unpaid interest on January 30, 1997. In addition, 
Borrower will pay regular quarterly payments of accrued unpaid interest 
beginning April 30, 1996, and all subsequent interest payments are due on the 
same day of each quarter after that. Interest on this Note is computed on a 
365/360 simple interest basis; that is, by applying the ratio of the annual 
interest rate over a year of 360 days, multiplied by the outstanding principal 
balance, multiplied by the actual number of days the principal balance is 
outstanding, unless such calculation would result in a usurious rate, in which 
case interest shall be calculated on a per diem basis of a year of 365 or 366 
days, as the case may be. Borrower will pay Lender at Lender's address shown 
above or at such other place as Lender may designate in writing. Unless 
otherwise agreed or required by applicable law, payments will be applied in any 
order at Lender's sole discretion. Notwithstanding any other provision of this 
Note, Lender will not charge interest on any undisbursed loan proceeds. No 
scheduled installment, whether of principal or interest or both, will be due 
unless sufficient loan funds have been disbursed by the scheduled installment 
date to justify the payment.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change from
time to time based on changes in an index which is the First Interstate Bank of 
Texas, N.A. Prime Rate, which is an index rate announced by Lender from time to 
time for pricing certain loans (the "Index"). The Index is not necessarily the 
lowest rate charged by Lender on its loans and is set by Lender in its sole 
discretion. If the Index becomes unavailable during the term of this loan, 
Lender may designate a substitute index after notifying Borrower. Lender will 
tell Borrower the current index rate upon Borrower's request. Borrower 
understands that Lender may make loans based on other rates as well. The 
interest rate change will not occur more often than each day. The Index
currently is 8.500% per annum. The interest rate to be applied prior to maturity
to the unpaid principal balance of this Note will be at a rate of 1.250
percentage points over the Index, resulting in an initial rate of 9.750% per
annum. NOTICE: Under no circumstances will the interest rate on this Note be
more than the maximum rate allowed by applicable law. For purposes of this Note,
the "maximum rate allowed by applicable law" means the greater of (a) the
maximum rate of interest permitted under federal or other law applicable to the
indebtedness evidenced by this Note, or (b) the "Indicated Rate Calling" as
referred to in Article 5069-1.04(a)(1) V.T.C.S.

PREPAYMENT. Borrower agrees that all loan fees and other prepaid finance charges
are earned fully as of the date of the loan and will not be subject to refund 
upon early payment (whether voluntary or as a result of default), except as 
otherwise required by law. Except for the foregoing, Borrower may pay without 
penalty all or a portion of the amount owed earlier than it is due. Early 
payments will not, unless agreed to by Lender in writing, relieve Borrower of 
Borrower's obligation to continue to make payments of accrued unpaid interest.

POST MATURITY RATE. the Post Maturity Rate on this Note is the lesser of the 
maximum rate allowed by applicable law or 9.250 percentage points over the 
Index. Borrower will pay interest on all sums due after final maturity, whether 
by acceleration or otherwise, at that rate, with the exception of any amounts 
added to the principal balance of this Note based on Lender's payment of 
insurance premiums, which will continue to accrue interest at the pre-maturity 
rate.

DEFAULT. Borrower will be in default if any of the following happens: (a) 
Borrower fails to make any payment when due, (b) Borrower breaks any promise 
Borrower has made to Lender, or Borrower fails to comply with or to perform when
due any other term, obligation, covenant, or condition contained in this Note or
any agreement related to this Note, or in any other agreement or loan Borrower 
has with Lender, (c) Any representation or statement made or furnished to Lender
by Borrower or on Borrower's behalf is false or misleading in any material 
respect either now or at the time made or furnished, (d) Borrower becomes 
insolvent, a receiver is appointed for any part of Borrower's property, Borrower
makes an assignment for the benefit of creditors, or any proceeding is commenced
either by Borrower or against Borrower under any bankruptcy or insolvency laws, 
(e) Any creditor tries to take any of Borrower's property on or in which Lender 
has a lien or security interest. This includes a garnishment of any of 
Borrower's accounts with Lender. (f) Any of the events described in this default
section occurs with respect to any guarantor of this Note, (g) A material 
adverse change occurs in Borrower's financial condition, or Lender believes the 
prospect of payment or performance of the Indebtedness is impaired.

LENDER'S RIGHTS. Upon default, Lender may declare the entire indebtedness, 
including the unpaid principal balance on this Note, all accrued unpaid 
interest, and all other amounts, costs and expenses for which Borrower is 
responsible under this Note or any other agreement with Lender pertaining to 
this loan, immediately due, without notice, and then Borrower will pay that 
amount. Lender may hire an attorney to help collect this Note if Borrower does 
not pay, and Borrower will pay Lender's reasonable attorneys' fees. Borrower 
also will pay Lender all other amounts actually incurred by Lender as court 
costs, lawful fees for filing, recording, or releasing to any public office any 
instrument securing this loan; the reasonable cost actually expended for 
repossessing, storing, preparing for sale, and selling any security; and fees 
for noting a lien on or transferring a certificate of title to any motor vehicle
offered as security for this loan, or premiums or identifiable charges 
received in connection with the sale of authorized insurance. This Note has been
delivered to Lender and accepted by Lender in the State of Texas. If there is a 
lawsuit, and if the transaction evidenced by this Note occurred in Harris 
County, Borrower agrees upon Lender's request to submit to the jurisdiction of 
the courts of Harris County, the State of Texas. Subject to the provisions on 
arbitration, this Note shall be governed by and construed in accordance with the
laws of the State of Texas and applicable Federal laws.

DISHONORED CHECK CHARGE. Borrower will pay a processing fee of $25.00 if any 
check given by Borrower to Lender as a payment on this loan is dishonored.

Loan No 42                       (Continued)
===============================================================================
RIGHT OF SETOFF. Borrower grants to Lender a contractual possessory security 
interest in, and hereby assigns, conveys, delivers, pledges, and transfers to 
Lender all Borrower's right, title and interest in and to, Borrower's accounts 
with Lender (whether checking, savings, or some other account), including 
without limitation all accounts held jointly with someone else and all accounts 
Borrower may open in the future, excluding however all IRA, Keogh, and trust 
accounts. Borrower authorizes Lender, to the extent permitted by applicable law,
to charge or setoff all sums owing on this Note against any and all such 
accounts.

LINE OF CREDIT. This Note evidences a revolving line of credit. Advances under 
this Note, as well as directions for payment from Borrower's accounts, may be 
requested orally or in writing by Borrower or by an authorized person. Lender 
may, but need not, require that all oral requests be confirmed in writing. 
Borrower agrees to be liable for all sums either: (a) advanced in accordance 
with the instructions of an authorized person or (b) credited to any of 
Borrower's accounts with Lender. The unpaid principal balance owing on this Note
at any time may be evidenced by endorsements on this Note or by Lender's 
internal records, including daily computer print-outs. Lender will have no 
obligation to advance funds under this Note if: (a) Borrower or any guarantor is
in default under the terms of this Note or any agreement that Borrower or any 
guarantor has with Lender, including any agreement made in connection with the 
signing of this Note; (b) Borrower or any guarantor ceases doing business or is 
insolvent; (c) any guarantor seeks, claims or otherwise attempts to limit, 
modify or revoke such guarantor's guarantee of this Note or any other loan with 
Lender; or (d) Borrower has applied funds provided pursuant to this Note for 
purposes other than those authorized by Lender. This revolving line of credit 
shall not be subject to Chapter 15, Article 5069 V.T.C.S. (the Texas Credit 
Code).

ARBITRATION.

     Binding Arbitration. Upon the demand of any party, whether made before or
     after the institution of any judicial proceeding, any Dispute (as defined
     below) shall be resolved by binding arbitration in accordance with the
     terms of this Arbitration Program. A "Dispute" shall include any action,
     dispute, claim, or controversy of any kind, whether in contract or in tort,
     statutory or common law, legal or equitable, or otherwise, now existing or
     hereafter arising between the parties in any way arising out of, pertaining
     to or in connection with (a) any agreement, document or instrument to which
     this Arbitration Program is attached or in which it is referred to or any
     related agreements, documents, or instruments (the "Documents"), (b) all
     past, present, or future loans, notes, instruments, drafts, credits,
     accounts, deposit accounts, safe deposit boxes, safekeeping agreements,
     guarantees, letters of credit, goods or services, or other transactions,
     contracts or agreements of any kind whatsoever, (c) any past, present or
     future incidents, omissions, acts, errors, practices, or occurrences
     causing injury to either party whereby the other party or its agents,
     employees or representatives may be liable, in whole or in part, or (d) any
     other aspect of the past, present, or future relationships of the parties
     including any agency, independent contractor or employment relationship but
     excluding claims for workers' compensation and unemployment benefits
     ("Relationship"). Any party to this Arbitration Program may by summary
     proceedings bring any action in court to compel arbitration of any Dispute.
     Any party who fails or refuses to submit to binding arbitration following a
     lawful demand by the opposing party shall bear all costs and expenses
     incurred by the opposing party in compelling arbitration of any Dispute.
     The parties agree that by the engaging in activities with or involving each
     other as described above, they are participating in transactions involving
     interstate commerce. THE PARTIES UNDERSTAND THAT PURSUANT TO THIS
     ARBITRATION PROGRAM, DISPUTES SUBMITTED TO ARBITRATION WILL NOT BE DECIDED
     THROUGH LITIGATION IN FEDERAL OR STATE COURTS BEFORE A JUDGE OR JURY.

     Governing Rules. All Disputes between the parties submitted to arbitration
     shall be resolved by binding arbitration administered by the American
     Arbitration Association (the "AAA") in accordance with the Commercial
     Arbitration Rules of the AAA, the Federal Arbitration Act (Title 9 of the
     United States Code) and to the extent the foregoing are inapplicable,
     unenforceable or invalid, the laws of the State of Texas. In the event of
     any inconsistency between this Arbitration Program and such rules and
     statutes, this Arbitration Program shall control. Judgment upon any award
     rendered hereunder may be entered in any court having jurisdiction;
     provided, however, that nothing contained herein shall be deemed to be a
     waiver by any party that is a bank of the protections afforded to it under
     12 U.S.C. Section 91 or Texas Banking Code art. 342-609.

     No Waiver; Preservation of Remedies; Multiple Parties. No provision of, nor
     the exercise of any rights under, this Arbitration Program shall limit the
     right of any party, during any Dispute, to seek, use, and employ ancillary
     or preliminary remedies, judicial or otherwise, for the purposes of
     realizing upon, preserving, protecting, foreclosing or proceeding under
     forcible entry and detainer for possession of any real or personal
     property, and any such action shall not be deemed an election of remedies.
     Such rights shall include, without limitation, rights and remedies relating
     to (a) foreclosing against any real or personal property collateral or
     other security, (b) exercising self-help remedies including setoff rights
     or (c) obtaining provisional or ancillary remedies such as injunctive
     relief, sequestration, attachment, garnishment, or the appointment of a
     receiver from a court having jurisdiction. Such rights can be exercised at
     any time except to the extent such action is contrary to a final award or
     decision in any arbitration proceeding. The institution and maintenance of
     an action for judicial relief or pursuit of provisional or ancillary
     remedies or exercise of self-help remedies shall not constitute a waiver of
     the right of any party, including the plaintiff, to submit the Dispute to
     arbitration, nor render inapplicable the compulsory arbitration provisions
     hereof. In Disputes involving indebtedness or other monetary obligations,
     each party agrees that the other party may proceed against all liable
     persons, jointly or severally, or against one or more of them, less than
     all, without impairing rights against other liable persons. Nor shall a
     party be required to join the principal obligator or any other liable
     persons, such as sureties or guarantors, in any proceeding against a
     particular person. A party may release or settle with one or more liable
     persons without releasing or impairing rights to proceed against any
     persons not so released.

     Arbitrator Powers and Qualifications; Awards. Arbitrators are empowered to
     resolve Disputes by summary rulings. Arbitrators shall resolve all Disputes
     in accordance with the applicable substantive law. Any arbitrator selected
     shall be required to be a practicing attorney licensed to practice law in
     the State of Texas and shall be required to be experienced and
     knowledgeable in the substantive laws applicable to the subject matter of
     the Dispute. All statutes of limitation applicable to any Dispute shall
     apply to any proceeding in accordance with this Arbitration Program. With
     respect to a Dispute in which the claims or amounts in controversy do not
     exceed $1,000,000, a single arbitrator shall be chosen and shall resolve
     the Dispute by rendering an award not to exceed $1,000,000, including all
     damages of any kind whatsoever, including costs, fees and expenses. A
     Dispute involving claims or amounts in controversy exceeding $1,000,000,
     shall be decided by a majority vote of a panel of three arbitrators (an
     "Arbitration Panel"), the determination of any two of the three arbitrators
     constituting the determination of the Arbitration Panel, provided, however,
     that all three Arbitrators on the Arbitration Panel must actively
     participate in all hearings and deliberations. Arbitrators, including any
     Arbitration Panel, may grant any remedy or relief deemed just and equitable
     and within the scope of this Arbitration Program and may also grant such
     ancillary relief as is necessary to make effective any award. Arbitrators
     shall be empowered to impose sanctions and to take such other actions as
     they deem necessary to the same extent a judge could pursuant to the
     Federal Rules of Civil Procedure, the Texas Rules of Civil Procedure and
     applicable law. Arbitrators and Arbitration Panels shall be required to
     make specific, written findings of fact and conclusions of law. The
     determination of an Arbitrator or Arbitration Panel shall be binding on all
     parties and shall not be subject to further review or appeal except as
     otherwise allowed by applicable law.

     Miscellaneous. To the maximum extent practicable, the AAA, the Arbitrator
     (or the Arbitration Panel, as appropriate) and the parties shall take any
     action necessary to require that an arbitration proceeding hereunder shall
     be concluded within 180 days of the filing of the Dispute with the AAA.
     Arbitration proceedings hereunder shall be conducted in the State of Texas
     at a location selected by the Administrator. With respect to any Dispute,
     each party agrees that all discovery activities shall be expressly limited
     to matters directly relevant to the Dispute and any Arbitrator, Arbitration
     Panel and the AAA shall be required to fully enforce this requirement. This
     Arbitration Program constitutes the entire agreement of the parties with
     respect to its subject matter and supersedes all prior discussions,
     arrangements, negotiations, and other communications on dispute resolution.
     The provisions of this Arbitration Program shall survive any termination,
     amendment, or expiration of the Documents or the Relationship, unless the
     parties otherwise expressly agree in writing. To the extent permitted by
     applicable law, Arbitrators, including any

     Arbitration Panel, shall have the power to award recovery of all costs and
     fees (including attorneys' fees, administrative fees, and arbitrators'
     fees) to the prevailing party. This Arbitration Program may be amended,
     changed, or modified only by the express provisions of a writing which
     specifically refers to this Arbitration Program and which is signed by all
     the parties hereto. If any term, covenant, condition or provision of this
     Arbitration Program is found to be unlawful, invalid or unenforceable, such
     defect shall not affect the legality, validity or enforceability of the
     remaining parts of this Arbitration Program, and all such remaining parts
     hereof shall be valid and enforceable and have full force and effect as if
     the illegal, invalid or unenforceable part had not been included. Each
     party agrees to keep all Disputes subject to arbitration proceedings
     strictly confidential, except for disclosures of information required in
     the ordinary course of business of the parties or by applicable law or
     regulation.

ADVANCES. This Note evidences a line of credit and all advances made hereunder. 
Lender is not obligated to advance funds requested under this line of credit if 
the resulting principal balance of the indebtedness would exceed the above 
stated "Principal Amount" of this Note. However, in the event Lender advances 
funds in excess of such amount, such sums shall be deemed validly advanced under
the terms of this Note as if the principal amount of this Note had been amended 
and increased to accommodate such advances, and such sums shall be considered to
be a part of the indebtedness evidenced by this Note for all purposes and shall 
be secured by all applicable security instruments and guaranties as if such 
instruments had been amended to accommodate and include such advances. Lender 
reserves the right to require immediate repayment of amounts advanced in excess 
of the above stated "Principal Amount" of this Note plus unpaid accrued interest
on such amounts, and such actions shall not constitute a waiver of any rights of
Lender under this Note or any related loan documents or security agreements.

DEFAULT RATE OF INTEREST. Lender may, at its option and without notice, charge 
interest at a rate (the "Default Rate") equivalent to the Post Maturity Rate 
(not to exceed the maximum lawful rate) on any past due amounts of the 
Indebtedness for the number of days said amounts are past due. Amounts shall be 
considered past due when not paid on the date due, whether said amounts become 
due pursuant to the payment schedule or as a result of acceleration, or 
otherwise. Further, if Lender gives written notice to Borrower of any one or 
more defaults under the Note or any related Loan Documents and such defaults are
not cured completely and strictly in accordance with the terms of the notice of 
default within the period of time allowed by Lender for cure of same, Lender may
charge interest at the Default Rate on the entire amount of the Indebtedness 
until two business days after such defaults are cured and that fact is 
communicated to and confirmed by Lender. Lender's use of the remedies available 
to Lender upon the occurrence of an event of default shall not constitute an 
election of remedies or otherwise limit Lender's rights concerning other 
remedies available to Lender upon the occurrence of an event of default.

RENEWAL AND EXTENSION. This Note is given in renewal and extension and not in 
novation of the following described indebtedness. That certain Promissory Note 
dated January 30, 1995 in the amount of $1,000,000.00 executed by Borrower 
payable to Lender. It is further agreed that all liens and security interests 
securing said indebtedness are hereby renewed and extended to secure the Note 
and all renewals, extensions and modifications thereof. This note is also given 
in evidence of additional advances which may be made hereunder.

GENERAL PROVISIONS. If any part of this Note cannot be enforced, this fact will 
not affect the rest of the Note. In particular, this section means (among other 
things) that Borrower does not agree or intend to pay, and Lender does not agree
or intend to contract for, charge, collect, take, reserve or receive 
(collectively referred to herein as "charge or collect"), any amount in the 
nature of interest or in the nature of a fee for this loan, which would in any 
way or event (including demand, prepayment, or acceleration) cause Lender to 
charge or collect more for this loan than the maximum Lender would be permitted 
to charge or collect by federal law or the law of the State of Texas (as 
applicable). Any such excess interest or unauthorized fee shall, instead of 
anything stated to the contrary, be applied first to reduce the principal 
balance of this loan, and when the principal has been paid in full, be refunded 
to Borrower. The right to accelerate maturity of sums due under this Note does 
not include the right to accelerate any interest which has not otherwise accrued
on the date of such acceleration, and Lender does not intend to charge or 
collect any unearned interest in the event of acceleration. All sums paid or 
agreed to be paid to Lender for the use, forbearance or detention of sums due 
hereunder shall, to the extent permitted by applicable law, be amortized, 
prorated, allocated and spread throughout the full term of the loan evidenced by
this Note until payment in full so that the rate or amount of interest on 
account of the loan evidenced hereby does not exceed the applicable usury 
ceiling. Lender may delay or forgo enforcing any of its rights or remedies under
this Note without losing them. Borrower and any other person who signs, 
guarantees or endorses this Note, to the extent allowed by law, waive 
presentment, demand for payment, protest, notice of dishonor, notice of intent 
to accelerate the maturity of this Note, and notice of acceleration of the 
maturity of this Note. Upon any change in the terms of this Note, and unless 
otherwise expressly stated in writing, no party who signs this Note, whether as 
maker, guarantor, accommodation maker or endorser, shall be released from 
liability. All such parties agree that Lender may renew or extend (repeatedly 
and for any length of time) this loan, or release any party or guarantor or 
collateral; or impair, fail to realize upon or perfect Lender's security 
interest in the collateral without the consent of or notice to anyone. All such 
parties also agree that Lender may modify this loan without the consent of or 
notice to anyone other than the party with whom the modification is made.

PRIOR TO SIGNING THIS NOTE, BORROWER READ AND UNDERSTOOD ALL THE PROVISIONS OF 
THIS NOTE, INCLUDING THE VARIABLE INTEREST RATE PROVISIONS. BORROWER AGREES TO 
THE TERMS OF THE NOTE AND ACKNOWLEDGES RECEIPT OF A COMPLETED COPY OF THE NOTE.

Borrower: DRCA MEDICAL CORPORATION (TIN: 76-0203483)
          Three Riverway, Suite 1430
          Houston, TX 77056

Lender:   First Interstate Bank of Texas, N.A.
          Houston Central Private Client Services
          1000 Louisiana
          Houston, TX 77002

===============================================================================
Principal Amount: $500,000.00                           Initial Rate: 9.250%
Date of Note: February 15, 1996 

PROMISE TO PAY. DRCA MEDICAL CORPORATION ("Borrower") promises to pay to First 
Interstate Bank of Texas, N.A. ("Lender"), or order, in lawful money of the 
United States of America, the principal amount of Five Hundred Thousand & 00/100
Dollars ($500,000.00) or so much as may be outstanding, together with interest
on the unpaid outstanding principal balance of each advance. Interest shall be
calculated from the date of each advance until repayment of each advance or
maturity, whichever occurs first.

PAYMENT. Borrower will pay this loan in one payment of all outstanding 
principal plus all accrued unpaid interest on February 15, 1997. In addition, 
Borrower will pay regular monthly payments of accrued unpaid interest 
beginning March 15, 1996, and all subsequent interest payments are due on the 
same day of each month after that. Interest on this Note is computed on a 
365/360 simple interest basis; that is, by applying the ratio of the annual 
interest rate over a year of 360 days, multiplied by the outstanding principal 
balance, multiplied by the actual number of days the principal balance is 
outstanding, unless such calculation would result in a usurious rate, in which 
case interest shall be calculated on a per diem basis of a year of 365 or 366 
days, as the case may be. Borrower will pay Lender at Lender's address shown 
above or at such other place as Lender may designate in writing. Unless 
otherwise agreed or required by applicable law, payments will be applied in any 
order at Lender's sole discretion. Notwithstanding any other provision of this 
Note, Lender will not charge interest on any undisbursed loan proceeds. No 
scheduled installment, whether of principal or interest or both, will be due 
unless sufficient loan funds have been disbursed by the scheduled installment 
date to justify the payment.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change from
time to time based on changes in an index which is the First Interstate Bank of 
Texas, N.A. Prime Rate, which is an index rate Lender announces from time to 
time for pricing certain loans (the "Index"). The Index is not necessarily the 
lowest rate charged by Lender on its loans and is set by Lender in its sole 
discretion. If the Index becomes unavailable during the term of this loan, 
Lender may designate a substitute index after notifying Borrower. Lender will 
tell Borrower the current index rate upon Borrower's request. Borrower 
understands that Lender may make loans based on other rates as well. The 
interest rate change will not occur more often than each day. The Index
currently is 8.250% per annum. The interest rate to be applied prior to maturity
to the unpaid principal balance of this Note will be at a rate of 1.000
percentage points over the Index, resulting in an initial rate of 9.250% per
annum. NOTICE: Under no circumstances will the interest rate on this Note be
more than the maximum rate allowed by applicable law. For purposes of this Note,
the "maximum rate allowed by applicable law" means the greater of (a) the
maximum rate of interest permitted under federal or other law applicable to the
indebtedness evidenced by this Note, or (b) the "Indicated Rate Calling" as
referred to in Article 5069-1.04(a)(1) V.T.C.S.

PREPAYMENT. Borrower may pay without penalty all or a portion of the amount owed
earlier than it is due. Early payments will not, unless agreed to by Lender in
writing, relieve Borrower of Borrower's obligation to continue to make payments
of accrued unpaid interest.

POST MATURITY RATE. The Post Maturity Rate on this Note is the lesser of the 
maximum rate allowed by applicable law or 9.000 percentage points over the 
index. Borrower will pay interest on all sums due after final maturity, whether 
by acceleration or otherwise, at that rate, with the exception of any amounts 
added to the principal balance of this Note based on Lender's payment of 
insurance premiums, which will continue to accrue interest at the pre-maturity 
rate.

DEFAULT. Borrower will be in default if any of the following happens: (a) 
Borrower fails to make any payment when due; (b) Borrower breaks any promise 
Borrower has made to Lender, or Borrower fails to comply with or to perform when
due any other term, obligation, covenant, or condition contained in this Note or
any agreement related to this Note, or in any other agreement or loan Borrower 
has with Lender; (c) Any representation or statement made or furnished to Lender
by Borrower or on Borrower's behalf is false or misleading in any material 
respect either now or at the time made or furnished; (d) Borrower becomes 
insolvent, a receiver is appointed for any part of Borrower's property, Borrower
makes an assignment for the benefit of creditors, or any proceeding is commenced
either by Borrower or against Borrower under any bankruptcy or insolvency laws.
(e) Any creditor tries to take any of Borrower's property on or in which Lender 
has a lien or security interest. This includes a garnishment of any of 
Borrower's accounts with Lender. (f) Any of the events described in this default
section occurs with respect to any guarantor of this Note. (g) A material 
adverse change occurs in Borrower's financial condition, or Lender believes the 
prospect of payment or performance of the Indebtedness is impaired.

LENDER'S RIGHTS. Upon default, Lender may declare the entire indebtedness, 
including the unpaid principal balance on this Note, all accrued unpaid 
interest, and all other amounts, costs and expenses for which Borrower is 
responsible under this Note or any other agreement with Lender pertaining to 
this loan, immediately due, without notice, and then Borrower will pay that 
amount. Lender may hire an attorney to help collect this Note if Borrower does 
not pay, and Borrower will pay Lender's reasonable attorneys' fees. Borrower 
also will pay Lender all other amounts actually incurred by Lender as court 
costs, lawful fees for filing, recording, or releasing to any public office any 
instrument securing this loan; the reasonable cost actually expended for 
repossessing, storing, preparing for sale, and selling any security; and fees 
for noting a lien on or transferring a certificate of title to any motor vehicle
offered as security for this loan, or premiums or identifiable charges 
received in connection with the sale of authorized insurance. This Note has been
delivered to Lender and accepted by Lender in the State of Texas. If there is a 
lawsuit, and if the transaction evidenced by this Note occurred in Harris 
County, Borrower agrees upon Lender's request to submit to the jurisdiction of 
the courts of Harris County, the State of Texas. Subject to the provisions on 
arbitration, this Note shall be governed by and construed in accordance with the
laws of the State of Texas and applicable Federal laws.

DISHONORED CHECK CHARGE. Borrower will pay a processing fee of $25.00 if any 
check given by Borrower to Lender as a payment on this loan is dishonored.

RIGHT OF SETOFF. Borrower grants to Lender a contractual possessory security 
interest in, and hereby assigns, conveys, delivers, pledges, and transfers to 
Lender all Borrower's rights, title and interest in and to, Borrower's accounts 
with Lender (whether checking, savings, or some other account), including 
without limitation all accounts held jointly with someone else and all accounts 
Borrower may open in the future, excluding however, all IRA, Keogh, and trust 
accounts. Borrower authorizes Lender, to the extent permitted by applicable law,
to charge or setoff all sums owing on this Note against any and all such 
accounts.

LINE OF CREDIT. This Note evidences a straight line of credit. Once the total 
amount of principal has been advanced, Borrower is not entitled to further loan 
advances. Advances under this Note may be requested orally by Borrower or by an 
authorized person. All oral requests shall be confirmed in writing on the day of
the request. All communications, instructions, or directions by telephone or 
otherwise to Lender are to be directed to Lender's office shown above. The 
following party or parties are authorized to request advances under the line of 
credit until Lender receives from Borrower at Lender's address shown above 
written notice of revocation of their authority: Jose Kauachi and Jeff Casey. 
Borrower agrees to be liable for all sums either: (a) advanced in accordance 
with the instructions of an authorized person or (b) credited to any of 
Borrower's accounts with Lender. The unpaid principal balance owing on this Note
at any time may be evidenced by endorsements on this Note or by Lender's 
internal records, including daily computer print-outs. Lender will have no 
obligation to advance funds under this Note if: (a) Borrower or any guarantor is
in default under the terms of this Note or any agreement that Borrower or any 
guarantor has with Lender, including any agreement made in connection with the
signing of this Note; (b) Borrower or any guarantor ceases doing business or is 
insolvent; (c) any guarantor seeks, claims or otherwise attempts to limit, 
modify or revoke such guarantor's guarantee of this Note or any other loan with 
Lender; or (d) Borrower has applied funds provided pursuant to this Note for 
purposes other than those authorized by Lender. 

ARBITRATION.

     Binding Arbitration. Upon the demand of any party, whether made before or
     after the institution of any judicial proceeding, any Dispute (as defined
     below) shall be resolved by binding arbitration in accordance with the
     terms of this Arbitration Program. A "Dispute" shall include any action,
     dispute, claim, or controversy of any kind, whether in contract or in tort,
     statutory or common law, legal or equitable, or otherwise, now existing or
     hereafter arising between the parties in any way arising out of, pertaining
     to or in connection with (a) any agreement, document or instrument to which
     this Arbitration Program is attached or in which it is referred to or any
     related agreements, documents, or instruments (the "Documents"), (b) all
     past, present, or future loans, notes, instruments, drafts, credits,
     accounts, deposit accounts, safe deposit boxes, safekeeping agreements,
     guarantees, letters of credit, goods or services, or other transactions,
     contracts or agreements of any kind whatsoever, (c) any past, present or
     future incidents, omissions, acts, errors, practices, or occurrences
     causing injury to either party whereby the other party or its agents,
     employees or representatives may be liable, in whole or in part, or (d) any
     other aspect of the past, present, or future relationships of the parties
     including any agency, independent contractor or employment relationship but
     excluding claims for workers' compensation and unemployment benefits
     ("Relationship"). Any party to this Arbitration Program may by summary
     proceedings bring any action in court to compel arbitration of any Dispute.
     Any party who fails or refuses to submit to binding arbitration following a
     lawful demand by the opposing party shall bear all costs and expenses
     incurred by the opposing party in compelling arbitration of any Dispute.
     The parties agree that by the engaging in activities with or involving each
     other as described above, they are participating in transactions involving
     interstate commerce. THE PARTIES UNDERSTAND THAT PURSUANT TO THIS
     ARBITRATION PROGRAM, DISPUTES SUBMITTED TO ARBITRATION WILL NOT BE DECIDED
     THROUGH LITIGATION IN FEDERAL OR STATE COURTS BEFORE A JUDGE OR JURY.

     Governing Rules. All Disputes between the parties submitted to arbitration
     shall be resolved by binding arbitration administered by the American
     Arbitration Association (the "AAA") in accordance with the Commercial
     Arbitration Rules of the AAA, the Federal Arbitration Act (Title 9 of the
     United States Code) and to the extent the foregoing are inapplicable,
     unenforceable or invalid, the laws of the State of Texas. In the event of
     any inconsistency between this Arbitration Program and such rules and
     statutes, this Arbitration Program shall control. Judgment upon any award
     rendered hereunder may be entered in any court having jurisdiction;
     provided, however, that nothing contained herein shall be deemed to be a
     waiver by any party that is a bank of the protections afforded to it under
     12 U.S.C. Section 91 or Texas Banking Code art. 342-609.

     No Waiver; Preservation of Remedies; Multiple Parties. No provision of, nor
     the exercise of any rights under, this Arbitration Program shall limit the
     right of any party, during any Dispute, to seek, use, and employ ancillary
     or preliminary remedies, judicial or otherwise, for the purposes of
     realizing upon, preserving, protecting, foreclosing or proceeding under
     forcible entry and detainer for possession of any real or personal
     property, and any such action shall not be deemed an election of remedies.
     Such rights shall include, without limitation, rights and remedies relating
     to (a) foreclosing against any real or personal property collateral or
     other security, (b) exercising self-help remedies including setoff rights
     or (c) obtaining provisional or ancillary remedies such as injunctive
     relief, sequestration, attachment, garnishment, or the appointment of a
     receiver from a court having jurisdiction. Such rights can be exercised at
     any time except to the extent such action is contrary to a final award or
     decision in any arbitration proceeding. The institution and maintenance of
     an action for judicial relief or pursuit of provisional or ancillary
     remedies or exercise of self-help remedies shall not constitute a waiver of
     the right of any party, including the plaintiff, to submit the Dispute to
     arbitration, nor render inapplicable the compulsory arbitration provisions
     hereof. In Disputes involving indebtedness or other monetary obligations,
     each party agrees that the other party may proceed against all liable
     persons, jointly or severally, or against one or more of them, less than
     all, without impairing rights against other liable persons. Nor shall a
     party be required to join the principal obligator or any other liable
     persons, such as sureties or guarantors, in any proceeding against a
     particular person. A party may release or settle with one or more liable
     persons without releasing or impairing rights to proceed against any
     persons not so released.

     Arbitrator Powers and Qualifications; Awards. Arbitrators are empowered to
     resolve Disputes by summary rulings. Arbitrators shall resolve all Disputes
     in accordance with the applicable substantive law. Any arbitrator selected
     shall be required to be a practicing attorney licensed to practice law in
     the State of Texas and shall be required to be experienced and
     knowledgeable in the substantive laws applicable to the subject matter of
     the Dispute. All statutes of limitation applicable to any Dispute shall
     apply to any proceeding in accordance with this Arbitration Program. With
     respect to a Dispute in which the claims or amounts in controversy do not
     exceed $1,000,000, a single arbitrator shall be chosen and shall resolve
     the Dispute by rendering an award not to exceed $1,000,000, including all
     damages of any kind whatsoever, including costs, fees and expenses. A
     Dispute involving claims or amounts in controversy exceeding $1,000,000,
     shall be decided by a majority vote of a panel of three arbitrators (an
     "Arbitration Panel"), the determination of any two of the three arbitrators
     constituting the determination of the Arbitration Panel, provided, however,
     that all three Arbitrators on the Arbitration Panel must actively
     participate in all hearings and deliberations. Arbitrators, including any
     Arbitration Panel, may grant any remedy or relief deemed just and equitable
     and within the scope of this Arbitration Program and may also grant such
     ancillary relief as is necessary to make effective any award. Arbitrators
     shall be empowered to impose sanctions and to take such other actions as
     they deem necessary to the same extent a judge could pursuant to the
     Federal Rules of Civil Procedure. the Texas Rules of Civil Procedure and
     applicable law. Arbitrators and Arbitration Panels shall be required to
     make specific, written findings of fact and conclusions of law. The
     determination of an Arbitrator or Arbitration Panel shall be binding on all
     parties and shall not be subject to further review or appeal except as
     otherwise allowed by applicable law.

     Miscellaneous. To the maximum extent practicable, the AAA, the Arbitrator
     (or the Arbitration Panel, as appropriate) and the parties shall take any
     action necessary to require that an arbitration proceeding hereunder shall
     be concluded within 180 days of the filing of the Dispute with the AAA.
     Arbitration proceedings hereunder shall be conducted in the State of Texas
     at a location selected by the Administrator. With respect to any Dispute,
     each party agrees that all discovery activities shall be expressly limited
     to matters directly relevant to the Dispute and any Arbitrator, Arbitration
     Panel and the AAA shall be required to fully enforce this requirement. This
     Arbitration Program constitutes the entire agreement of the parties with
     respect to its subject matter and supersedes all prior discussions,
     arrangements, negotiations, and other communications on dispute resolution.
     The provisions of this Arbitration Program shall survive any termination,
     amendment, or expiration of the Documents or the Relationship, unless the
     parties otherwise expressly agree in writing. To the extent permitted by
     applicable law, Arbitrators, including any Arbitration Panel, shall have
     the power to award recovery of all costs and fees (including attorneys'
     fees, administrative fees, and arbitrators' fees) to the prevailing party.
     This Arbitration Program may be amended, changed, or modified only by the
     express provisions of a writing which specifically refers to this
     Arbitration Program and which is signed by all the parties hereto. If any
     term, covenant, condition or provision of this Arbitration Program is found
     to be unlawful, invalid or unenforceable, such defect shall not affect the
     legality, validity or enforceability of the

Loan No                          (Continued)
===============================================================================

     remaining parts of this Arbitration Program, and all such remaining parts
     hereof shall be valid and enforceable and have full force and effect as if
     the illegal, invalid or unenforceable part had not been included. Each
     party agrees to keep all Disputes subject to arbitration proceedings
     strictly confidential, except for disclosures of information required in
     the ordinary course of business of the parties or by applicable law or
     regulation.

ADVANCES. This Note evidences a line of credit and all advances made hereunder. 
Lender is not obligated to advance funds requested under this line of credit if 
the resulting principal balance of the indebtedness would exceed the above 
stated "Principal Amount" of this Note. However, in the event Lender advances 
funds in excess of such amount, such sums shall be deemed validly advanced under
the terms of this Note as if the principal amount of this Note had been amended 
and increased to accommodate such advances, and such sums shall be considered to
be a part of the indebtedness evidenced by this Note for all purposes and shall 
be secured by all applicable security instruments and guaranties as if such 
instruments had been amended to accommodate and include such advances. Lender 
reserves the right to require immediate repayment of amounts advanced in excess 
of the above stated "Principal Amount" of this Note plus unpaid accrued interest
on such amounts, and such actions shall not constitute a waiver of any rights of
Lender under this Note or any related loan documents or security agreements.

DEFAULT RATE OF INTEREST. Lender may, at its option and without notice, charge 
interest at a rate (the "Default Rate") equivalent to the Post Maturity Rate 
(not to exceed the maximum lawful rate) on any past due amounts of the 
Indebtedness for the number of days said amounts are past due. Amounts shall be 
considered past due when not paid on the date due, whether said amounts become 
due pursuant to the payment schedule or as a result of acceleration, or 
otherwise. Further, if Lender gives written notice to Borrower of any one or 
more defaults under the Note or any related Loan Documents and such defaults are
not cured completely and strictly in accordance with the terms of the notice of 
default within the period of time allowed by Lender for cure of same, Lender may
charge interest at the Default Rate on the entire amount of the Indebtedness 
until two business days after such defaults are cured and that fact is 
communicated to and confirmed by Lender. Lender's use of the remedies available 
to Lender upon the occurrence of an event of default shall not constitute an 
election of remedies or otherwise limit Lender's rights concerning other 
remedies available to Lender upon the occurrence of an event of default.

GENERAL PROVISIONS. If any part of this Note cannot be enforced, this fact will 
not affect the rest of the Note. In particular, this section means (among other 
things) that Borrower does not agree or intend to pay, and Lender does not agree
or intend to contract for, charge, collect, take, reserve or receive 
(collectively referred to herein as "charge or collect"), any amount in the 
nature of interest or in the nature of a fee for this loan, which would in any 
way or event (including demand, prepayment, or acceleration) cause Lender to 
charge or collect more for this loan than the maximum Lender would be permitted 
to charge or collect by federal law or the law of the State of Texas (as 
applicable). Any such excess interest or unauthorized fee shall, instead of 
anything stated to the contrary, be applied first to reduce the principal 
balance of this loan, and when the principal has been paid in full, be refunded 
to Borrower. The right to accelerate maturity of sums due under this Note does 
not include the right to accelerate any interest which has not otherwise accrued
on the date of such acceleration, and Lender does not intend to charge or 
collect any unearned interest in the event of acceleration. All sums paid or 
agreed to be paid to Lender for the use, forbearance or detention of sums due 
hereunder shall, to the extent permitted by applicable law, be amortized, 
prorated, allocated and spread throughout the full term of the loan evidenced by
this Note until payment in full so that the rate or amount of interest on 
account of the loan evidenced hereby does not exceed the applicable usury 
ceiling. Lender may delay or forgo enforcing any of its rights or remedies under
this Note without losing them. Borrower and any other person who signs, 
guarantees or endorses this Note, to the extent allowed by law, waive 
presentment, demand for payment, protest, notice of dishonor, notice of intent 
to accelerate the maturity of this Note, and notice of acceleration of the 
maturity of this Note. Upon any change in the terms of this Note, and unless 
otherwise expressly stated in writing, no party who signs this Note, whether as 
maker, guarantor, accommodation maker or endorser, shall be released from 
liability. All such parties agree that Lender may renew or extend (repeatedly 
and for any length of time) this loan, or release any party or guarantor or 
collateral; or impair, fail to realize upon or perfect Lender's security 
interest in the collateral without the consent of or notice to anyone. All such 
parties also agree that Lender may modify this loan without the consent of or 
notice to anyone other than the party with whom the modification is made.

PRIOR TO SIGNING THIS NOTE, BORROWER READ AND UNDERSTOOD ALL THE PROVISIONS OF 
THIS NOTE, INCLUDING THE VARIABLE INTEREST RATE PROVISIONS. BORROWER AGREES TO 
THE TERMS OF THE NOTE AND ACKNOWLEDGES RECEIPT OF A COMPLETED COPY OF THE NOTE.
