                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS






NOTE A  - BASIS OF PRESENTATION

   Effective April 3, 1998, Tatonka Energy, Inc. ("Tatonka") acquired 80% of the
   outstanding  capital stock of Phy Med Diagnostic Imaging Center Dallas,  Inc.
   ("Phy Med"),  pursuant to an agreement and plan of reorganization  and merger
   (the Agreement).  The Agreement provides that consideration  given by Tatonka
   consists of the  issuance  of  68,915,409  Tatonka  common  shares.  However,
   pending  shareholder  approval of an increase in the authorized common shares
   of Tatonka, only 39,583,513 shares have been issued. Shareholders' deficit in
   the  accompanying  balance  sheet  reflects  on the Tatonka  shares  actually
   issued. Pro forma shareholders'  deficit and pro forma loss per share reflect
   the  additional  29,331,896  shares  that  are  required  to be  issued  upon
   shareholder approval.

   At the date of the merger,  Tatonka had nominal  assets,  consisting  only of
   $116 in cash and no liabilities. The terms of the merger result in the former
   Phy Med  shareholders  owning  approximately  87% of the outstanding  Tatonka
   common   stock.   Therefore,   the  merger  has  been   accounted  for  as  a
   recapitalization of Phy Med. The accompanying financial statements which have
   been captioned "Tatonka Energy, Inc.", pending shareholder approval to change
   the name to Phy Med,  Inc.,  are those of Phy Med for all periods  presented.
   Phy Med is referred to herein as "the Company".

   The consolidated  financial statements contained herein have been prepared by
   the  Company  pursuant to the rules and  regulations  of the  Securities  and
   Exchange Commission. In the opinion of management,  all adjustments necessary
   for a fair presentation of the consolidated financial position as of June 30,
   1997 and 1998 have been made. In addition,  all such adjustments made, in the
   opinion of  management,  are of a normal  recurring  nature.  The  results of
   operations for the interim periods  presented are not necessarily  indicative
   of the results to be expected for the full fiscal year.

   Certain information and footnote  disclosures  normally included in financial
   statements   prepared  in  accordance  with  generally  accepted   accounting
   principles have been condensed or omitted for the interim periods pursuant to
   the interim  reporting rules of the Securities and Exchange  Commission.  The
   interim consolidated  financial statements should be read in conjunction with
   the audited consolidated financial statements and related notes of Phy. Med.,
   Inc. for the year ended  December 31, 1997,  included in the  Company's  Form
   8-K/A.

   sufficient to relate the cost of depreciable  assets to operations over their
   estimated  service  lives,  which  range  from  three to five  years,  by the
   straight-line   method.   Leasehold   improvements   are   amortized  by  the
   straight-line  method over the lives of the respective  leases or the service
   lives of the improvements, whichever is shorter.

   Deferred Rent

   The cost of the  Company's  lease for office  space is  accounted  for by the
   straight-line method. The difference between the net cash requirements of the
   lease and straight-line  method is reflected on the balance sheet as deferred
   rent.

   Use of Estimates

   In preparing  financial  statements in  conformity  with  generally  accepted
   accounting   principles,   management  is  required  to  make  estimates  and
   assumptions that effect the reported  amounts of assets and liabilities,  the
   disclosure of contingent  assets and liabilities at the date of the financial
   statements,  the  reported  amounts  of  revenues  and  expenses  during  the
   reporting period. Actual results could differ from those estimates.


NOTE C - LOSS PER SHARE

   Loss  per  share  has  been  calculated  based  upon  the  number  of  shares
   (39,583,513)  issued by Tatonka on April 3, 1998, for the  acquisition of Phy
   Med, with retroactive  application to all periods  presented.  For the period
   subsequent to April 3, 1998, weighted average shares outstanding include also
   the outstanding shares of Tatonka  (9,515,556) held by the pre-merger Tatonka
   shareholders.

   No effect has been given in the  calculation  of loss per share to the effect
   of the Series A convertible  preferred  stock,  because the result of assumed
   conversion is antidilutive.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED






NOTE D - FINANCING DEFAULTS

   At June 30, 1998, the Company was in arrears on payments due on a note to DVI
   Finance Company (DVI) (balance of $267,657 at June 30, 1998) and an equipment
   financing  lease (balance of $1,595,861 at June 30, 1998)  accounted for as a
   capital lease.

   In August  1998,  DVI filed a lawsuit  against the  Company  and  obtained an
   injunction  that  prohibits  the Company from  disbursing  funds  without the
   consent of DVI.  DVI has  indicated  it may apply to the court for a receiver
   for the  Company.  If DVI were to file  such an  application,  the  equipment
   lessor could be expected to join in the application.

   As a result of the lease default, the outstanding balance is subject to being
   called by the lender,  although no such demand has been made. The outstanding
   balances on the note and the equipment  lease have been classified as current
   liabilities in the balance sheet at June 30, 1998.

Six Months Ended June 30, 1998 Compared with Six Months Ended June 30, 1997

      Net patient  revenues  increased by 7.17% to $1,861,138 for the six months
ended June 30, 1998 from $1,736,632 for the six months ended June 30, 1997.

      Operating  expenses  increased  by 9.1% to  $1,794,975  for the six months
ended June 30, 1998 from  $1,644,883 for the six months ended June 30, 1997, due
primarily to the expenses resulting from the reorganization and merger effective
April 3, 1998 between  Tatonka  Energy,  Inc.  ("Tatonka")  and  Phy.Med.,  Inc.
("PhyMed")($100,000) ; the installation costs associated with a new

                                        9

<PAGE>



radiology   information  system  ($45,000);   and,  to  the  Company's  expanded
operations  through  its  capitated  services  contracts  ($168,000).  Operating
expenses, excluding the reorganization, systems installation costs and the costs
associated with the capitated  services contract decreased by 9.8% to $1,482,000
for the six  months  ended  June 30,  1998.  As a  percentage  of net  revenues,
operating expenses, excluding the reorganization, systems installation costs and
the costs associated with the capitated services contract,  decreased from 94.7%
for the six months  ended June 30,  1997 to 79.6% for the six months  ended June
30, 1998.

      Operating  profit  decreased  by 27.9% to $66,163 for the six months ended
June 30, 1998 from $91,749 for the six months ended June 30, 1997. This decrease
is due primarily to the reorganization and systems installation  expenses.  As a
percentage of net patient  revenues,  operating profit decreased to 3.6% for the
six months  ended June 30, 1998 from 5.3% in the  comparable  prior year period.
Operating profit, excluding the reorganization and systems installation expense,
increased by 229.9% to $211,000  for the six months  ended June 30,  1998.  As a
percentage   of  net  patient   revenues,   operating   profit,   excluding  the
reorganization and systems installation expense,  increased to 11.3% for the six
months ended June 30, 1998.

      Interest  expense  decreased by 38.9% to $128,844 for the six months ended
June 30,  1998 from  $211,047  for the six  months  ended  June 30,  1997.  This
decrease  was  attributable  primarily  to the notes  related to the purchase of
treasury  stock;  to the ESOP stock  acquisitions;  and,  to the  retirement  of
certain other equipment  related notes. As a percentage of net patient revenues,
interest  expense  decreased to 6.9% for the six months ended June 30, 1998 from
11.6% for the six months ended June 30, 1997.

      Other  expenses  include  factoring  fees  and  miscellaneous  income  and
expenses.  The Company is slowly reducing its use of the factoring firm and that
expense has  decreased  to $34,161  for the six months  ended June 30, 1998 from
$51,318 for the same period in 1997.  Factoring  fees,  as a  percentage  of net
patient revenues decreased from 3.0% in 1997 to 1.8% in 1998.

      Net loss  decreased  by 36.1% to a net loss of $65,220  for the six months
ended June 30,  1998 from net loss of  $102,054  for the  comparable  prior year
period.  This decrease is due  primarily to reduction of operating  expenses and
the decrease in interest expense.  Net income,  excluding the reorganization and
systems  installation  expense  of  $213,000  (less the  related  tax  effect of
$76,000) would have been approximately  $72,000,  compared to a net loss for the
six months ended June 30, 1997, of $102,054.

LIQUIDITY AND CAPITAL RESOURCES

      PhyMed was  started on an  original  investment  in 1990 of $1,000 and has
used factoring of account  receivables as a means of financing  internal  growth
and  operations.  Equipment has been acquired  through  capital  leases over the
years. The same factoring company has been used throughout  PhyMed's history. In
February 1998 the  factoring  company  demanded that PhyMed repay  approximately
$200,000 in uncollected old accounts. A compromise was reached reducing the

                                       10

<PAGE>



advance from the factor from 54% to 38%, approximately, of the face value of the
claims submitted until the old balance is retired.  PhyMed only submits worker's
compensation  claims for factoring.  These represent  approximately 25% of total
claims  filed.  The total  amount  outstanding  to the  factoring  firm has been
reduced from $758,755 at December 31, 1997 to $561,404 at June 30, 1998.

      The  reduction of  indebtedness  to the factoring  company  during the six
months  ended  June 30,  1998  resulted  in  $197,351  less cash  available  for
operations.   This   coupled  with  the   one-time   expenses   related  to  the
reorganization  and a systems  installation  resulted in an increase in accounts
payable and accrued  expenses at June 30, 1998.  PhyMed is in default on certain
equipment   financings  with  Siemens  Credit  Corporation   ("Siemens")  and  a
subsidiary of DVI Capital ("DVI"). These financings constitute $1,985,268 of the
$2,452,398 of long-term debt  (including  current  maturities)  reflected on the
Company's June 30,1998 Consolidated Balance Sheet.  Additionally the real estate
lease  related to the premises  occupied by PhyMed is in default and at November
30,  1998 was in  arrears  approximately  $49,269.44.  Although  PhyMed has made
payments as its cash flow  permitted,  at June 30, 1998,  these  financings  and
lease are over 90 days in arrears, and under the financing terms are in default.

      At June 30, 1998 PhyMed was  continuing to make partial  payments on these
obligations and was negotiating with DVI and Siemens about  restructuring  these
financings.  In August 1998, DVI filed suit seeking payment on its financing and
obtained an injunction  against PhyMed  disbursing  funds without the consent of
DVI. During the existence of the injunction, DVI has consented to the payment of
payroll and other  essential  expenses,  as well as payment to DVI.  During this
period,  payments  have not been paid to Siemens and are in arrears  $295,446 at
November 30, 1998. It has not threatened to initiate legal proceedings.

      At November 30, 1998 PhyMed still owes DVI approximately $264,338.  PhyMed
is currently  negotiating to refinance this  indebtedness.  DVI has indicated it
may apply to the court for the appointment of a receiver for PhyMed. If DVI were
to  file  such  an  application,  Siemens  could  be  expected  to  join  in the
application,  too. If the court granted the application,  the present management
of PhyMed and Tatonka  Energy,  Inc.  would lose control of PhyMed until Siemens
and DVI, their attorneys and the cost of the receivership had been paid in full.
If the Company,  through PhyMed,  were unable to continue to have the use of the
equipment,  the lack of availability would have a material adverse effect on the
Company.

      In addition,  PhyMed is working with other financing  sources to refinance
its accounts  receivable,  which would pay-off the present  factoring  company's
balance  as  of  November  30,  1998,  of  approximately  $365,883  and  provide
approximately  $435,000  in  working  capital.  There is no  assurance  that any
restructuring or refinancing will take place or that it will take place in terms
favorable to PhyMed.

      The  defaults  under the  equipment  financing  and real estate lease also
constitute a  non-monetary  event of default under  PhyMed's 1993 loan agreement
with Alan Luckett.  He is a founder and former 50% owner of PhyMed.  This credit
is for the installment payout portion of the price paid for the

                                       11

<PAGE>



1993  purchase of his stock by PhyMed and its Employee  Stock  Option  Plan.  On
October 24, 1998 Mr.  Luckett  signed a waiver of these  non-monetary  events of
default.

      Management is  developing a  refinancing  plan that it believes will allow
the Company to increase its financial strength;  and, grow through  acquisitions
and increase in same store  sales.  However,  there is no assurance  the Company
will be able to accomplish any of this, or do so profitably.

EFFECTS OF INFLATION

      Inflation  is not a material  factor  affecting  the  Company's  business.
General operating  expenses such as salaries and employee benefits are, however,
subject to normal inflationary pressures.


SEASONALITY

      The  Company's  results  of  operations,   have,  in  some  years,  varied
significantly  from quarter to quarter,  for reasons particular to each quarter.
For  instance,  hospital  admissions  and doctor  visits  (and,  therefore,  the
Company's imaging  revenues) are typically lower during holiday periods,  and at
other times when physicians traditionally take their own vacations.

GENERAL TRENDS AND UNCERTAINTIES

      The  Company's   future   revenues  and  results  of  operations   may  be
substantially affected by proposed reforms of the nation's healthcare system and
by potential  reductions in reimbursement  rates and policies imposed by federal
and state government and other  third-party  reimbursement  programs (from which
the Company derives a material portion of its receipts). Continuing pressures on
pricing structures  applicable to the Company's services,  or inability to renew
existing contracts, could have the effect of reducing the Company's revenues and
operating profit margins.  The Company is unable to predict the nature or extent
of any such changes and/or the effects thereof on the Company.

         Not applicable.

Item 2.  Changes in Securities and Use of Proceeds

      On April 3,  1998,  George  C.  Barker,  ("Barker"),  individually  and as
Trustee for the  Phy.Med.,  Inc.  Employee  Stock  Ownership  Plan (the "ESOP"),
acquired control of the Company.  Prior to such date, such parties owned all the
outstanding shares of Phy.Med., Inc., a Texas corporation

                                       12

<PAGE>



("PhyMed"),  and on such date they acquired from the Company,  in the aggregate,
immediate  ownership  of and the right to receive  an  aggregate  of  68,915,409
authorized but unissued shares of Common Stock, $.001 par value, of the Company,
as presently constituted,  which, if all such shares were presently outstanding,
would constitute 87.9% of the Company's then  outstanding  78,430,965  shares of
Common Stock (86.9% of the  79,331,896  shares which would be  outstanding  on a
fully diluted basis).

      The terms of the  acquisition  contemplate a 1-for-10  reverse stock split
which  will  become   effective   shortly  after  the  1998  Annual  Meeting  of
Shareholders.  Upon the effectiveness of such reverse split, Barker and the ESOP
will own  6,891,541  shares of  7,843,097  shares,  $.01 par value,  outstanding
(7,933,190  shares on a full diluted basis).  (The Company will continue to have
50,000,000 shares of Common Stock authorized.)

      On March 6, 1998,  certain  parties  entered into an Agreement and Plan of
Reorganization  and Merger (the  "Agreement").  The parties  were Barker and the
ESOP,  in their  capacity as the  shareholders  of PhyMed,  PhyMed  itself,  the
Company and Tatonka Subsidiary, Inc., a newly-formed and wholly-owned subsidiary
of the Company.  The Agreement was  consummated  on April 3, 1998, by means of a
statutory merger of Tatonka Subsidiary,  Inc. into PhyMed, with PhyMed being the
surviving  corporation.  As a result of the  merger,  PhyMed is now an 80% owned
subsidiary of the Company, and the ESOP owns the remaining 20% of PhyMed.

      Prior to the merger,  there were 800 common shares of PhyMed  outstanding,
of which 500 were owned by Barker, individually, and 300 were owned by the ESOP.

      In the merger, the 500 PhyMed common shares owned by Barker were converted
into immediate ownership of and the right to receive 53,840,163 shares of Common
Stock of the Company,  and 140 of the 300 PhyMed common shares owned by the ESOP
were  converted  in like manner into  15,075,246  shares of Common  Stock of the
Company.  The remaining 160 PhyMed common shares held by the ESOP now constitute
the 20% of PhyMed common shares not owned by the Company.

      The Company has 50,000,000  shares of Common Stock authorized for issuance
and, at the time of the merger,  had 9,916,487  shares issued and outstanding or
reserved  for  issuance.  To the extent that the terms of the merger  would have
resulted  in the  issuance  of more than  50,000,000  shares,  the  excess  over
50,000,000  shall  not be issued  until  such  time as the  stockholders  of the
Company have approved an appropriate  amendment to the Company's  Certificate of
Incorporation. Prior to such approval, Barker and the ESOP will continue to have
a contractual right,  pursuant to the Agreement and the Articles of Merger filed
with the Secretary of State of Texas at the time of the merger,  to receive such
excess shares, subject to such required stockholder approval.

      In summary, Barker and the ESOP received an aggregate of 39,583,513 shares
of the Company at the time of the merger, the same being 80.6% of the 49,099,069
shares  then  outstanding.  Of  such  number,  Barker,  individually,   received
30,924,620 shares  (approximately  63%) of the outstanding  shares, and the ESOP
received  8,658,893  shares   (approximately   17.6%),  both  percentages  on  a
fully-diluted basis.


                                       13

<PAGE>



      Barker and the ESOP  continue to have a contractual  right to receive,  in
the  aggregate,  an  additional  29,331,896  shares,  which will result in their
having, collectively,  86.9% of the then outstanding Common Stock of the Company
on a fully-diluted basis. Of such additional shares, 22,915,544 will be received
by Barker, individually, and 6,416,352 shares will be received by the ESOP.

      The parties to the Agreement  contemplate  that the Board of Directors and
stockholders  of  the  Company  will  approve  an  amendment  to  the  Company's
Certificate  of  Incorporation   approving  a  1-  for-10  reverse  stock  split
(including  an increase in the par value of the Common Stock from $.001 to $.01)
and a change of the Company's name to "PhyMed,  Inc.". Upon the effectiveness of
such reverse stock split, all outstanding shares of common stock of the Company,
including  the  shares  which  were  issued  to  Barker  and the  ESOP  upon the
effectiveness of the merger,  will represent  one-tenth (1/10th) as many shares.
In addition,  all shares  reserved for issuance,  including the shares which the
Company  will still  have a  contractual  obligation  to issue to Barker and the
ESOP,  will become  rights to receive  one-tenth  (1/10th) as many  shares.  The
unissued shares due Barker and the ESOP from the merger will then be immediately
issued because the Company will then have a sufficient  number of authorized but
unissued shares to issue for this purpose.

                                  AMENDMENT TO

                 AGREEMENT AND PLAN OF REORGANIZATION AND MERGER

      This  Amendment to Agreement and Plan of  Reorganization  and Merger (this
"Amendment"),  is dated as of March 6, 1998, by and among TATONKA ENERGY,  INC.,
an Oklahoma corporation  ("Tatonka"),  TATONKA ENERGY SUBSIDIARY,  INC., a Texas
corporation and a wholly-owned subsidiary of Tatonka ("Tatonka Sub"), PHY. MED.,
INC., a Texas corporation (the "Company") and GEORGE C. BARKER, a Texas resident
("Barker")  and the  EMPLOYEE  STOCK  OWNERSHIP  PLAN OF PHY.  MED.,  INC.  (the
"ESOP")(Barker and the ESOP are collectively the "Stockholders").

                                    Recitals


      A. The parties have entered into an Agreement  and Plan of  Reorganization
and  Merger  dated as of March 6,  1998  (the  "Agreement"),  pursuant  to which
Tatonka, Tatonka Sub, and the Company intend that Tatonka Sub be merged with and
into the  Company,  and  that the  Company  be the  sole  surviving  corporation
(sometimes  called  the  "Surviving  Corporation"),   and  Tatonka  Sub  be  the
disappearing corporation (sometimes called the "Disappearing Corporation").

      B. Tatonka,  Tatonka Sub and the Company have each determined to engage in
the  transactions  contemplated  hereby,  pursuant to which (i) Tatonka Sub will
merge with and into the Company upon the terms and  conditions set forth in this
Agreement and in accordance with the laws of the State of Texas, (ii) 80% of the
outstanding  shares of the Company  Common Stock shall be converted at such time
into shares of common stock, par value $.001 per share, of Tatonka (the "Tatonka
Common  Stock")  as set forth in this  Agreement,  and (iii) the  Company  shall
become an 80% owned subsidiary of Tatonka.

      C.  Recital  F of  the  Agreement  incorrectly  states  that  Tatonka  has
9,916,487  shares of  Common  Stock  issued  and  outstanding  or  reserved  for
issuance, when the correct number is 10,416,487 shares issued and outstanding or
reserved for issuance.

      D.  Section  2.11  contains  several   erroneous  numbers  of  shares  and
percentages.

      E.  "Exhibit A-Merger  Consideration" to  Exhibit "A" to  the  Articles of
Merger erroneously

                                       20

<PAGE>



states:

      "The  Stockholders  shall  receive the following  Tatonka  Common Stock as
      their Merger Consideration:

      George C. Barker.........................................54,230,788 shares
      The ESOP..................................................5,184,621 shares
      Total Merger Consideration..............................69,415,409 shares"

      NOW,  THEREFORE,  in  consideration  of the  preceding  recitals and their
mutual desire that the Agreement read correctly,  the parties  mutually agree to
correct said errors, as follows:

      1. Recital F correctly reads as follows:

         "F.  Tatonka  has  50,000,000  shares of Common  Stock  authorized  for
      issuance and  10,416,487  shares  issued and  outstanding  or reserved for
      issuance.  Issuance at the effective  Time of all the shares  representing
      the Merger  Consideration  would  result in the issuance of more than such
      50,000,000 authorized shares."

      2.  Section  2.11 of  Exhibit  "A"  attached  to the  Articles  of  Merger
      correctly reads as follows:

         "Section  2.11  Percentage  Protection  Provision.  The parties to this
      Agreement  agree  that  they are  entering  into this  Agreement  with the
      intention that Barker and the ESOP will have at least 86.87% of the shares
      of Tatonka Common Stock  outstanding  after (a) the Effective Time and (b)
      the conversion of all the Tatonka Preferred Stock, but before the exercise
      of any of the three  stock  options  contemplated  to be issued by Tatonka
      (after  the  Effective  Time)  and  referred  to in  Section  4.4 of  this
      Agreement.  The  numbers  of shares of Tatonka  Common  Stock set forth on
      Exhibit A as being issued to Barker and the ESOP at the Effective Time are
      based on the assumptions that (a) no more than 9,515,556 shares of Tatonka
      Common  Stock,  as  presently  constituted,  will  be  outstanding  at the
      Effective Time (exclusive of any shares that may be issued upon conversion
      of Tatonka  Preferred Stock prior to the Effective Time), (b) no more than
      900,931 shares will be issued upon conversion of all the Tatonka Preferred
      Stock,  (c) no other  shares of  Tatonka  Common  Stock  will be issued by
      virtue of any rights to receive  any  shares of  Tatonka  Common  Stock or
      other  securities  of Tatonka that exist at the date of this  Agreement or
      will exist at the  Effective  Time,  and (d) the  aggregate of  10,416,487
      shares enumerated in (a) and (b) above will constitute no more than 13.13%
      of the  shares of  Tatonka  Common  Stock  outstanding  after  the  events
      described above.

                                       21

<PAGE>



         The parties to this Agreement  covenant and agree that if more than the
      10,416,487  shares of Tatonka  Common Stock  referred to in the  foregoing
      paragraph are ultimately issued by Tatonka as a consequence of the matters
      referred to in such paragraph, Tatonka shall issue to Barker and the ESOP,
      pro rata,  such  additional  number of shares of Tatonka  Common  Stock as
      shall be necessary to increase their  collective  ownership  percentage of
      all shares of Tatonka Common Stock  outstanding after the events described
      above to 86.87%."

      3. (2) "Exhibit A-Merger  Consideration," which is attached to Exhibit "A"
to the Articles of Merger, correctly reads as set forth below:


                        "Exhibit A - Merger Consideration
                                 (As Corrected)

      The Stockholders shall receive the following Tatonka Common Stock as their
      Merger Consideration:

      George C. Barker.........................................53,840,164 shares

      The ESOP.................................................15,075,245 shares

      Total Merger Consideration..............................68,915,409 shares"


      IN WITNESS  WHEREOF,  the parties  have duly  executed  this  Amendment to
Agreement  and Plan of  Reorganization  and Merger as of the date first  written
above.

of this Agreement,  Lender agrees to make the Advance,  pursuant to this Article
2.

      Section 2.2.   Note.  The Loan made by  Lender pursuant to  this Article 2

      Section 2.3    Interest Rate.  The outstanding  principal  balance  of the

                                   ARTICLE 3.

                                    INTEREST

      Section 3.1. Computation of Interest. Subject to the provisions of Section
3.2, all interest  payable  hereunder shall be computed for the actual number of
days elapsed during any period for which  interest is calculated  (including the
first day and excluding the last day) on the basis of a year consisting of three
hundred  sixty (360) days.  The interest  payable on the  outstanding  principal
balance  of the Loan  shall be  calculated  by first  determining  the amount of
interest on the principal  balance of the Loan  outstanding from time to time at
the Base  Interest  Rate  hereunder  from the Closing  Date  through the date of
determination,  then deducting the aggregate amount of interest  previously paid
on such principal  balance from time to time to determine the amount of interest
then  payable.  The  principal  balance of the Loan for the purpose of computing
interest  shall be the principal  balance of the Loan at the end of any Business
Day on which interest shall be computed hereunder.

      If a rate of interest  applicable to the Loan at any time would exceed the
Highest  Lawful Rate but for the  limitation  contained in section 3.2, then the
actual  rate of interest  to accrue on the unpaid  principal  amount of the Loan
shall be limited to the Highest Lawful Rate,  but any  subsequent  reductions in
such  applicable rate shall not reduce the interest rate payable upon the unpaid
amount thereof below the Highest Lawful Rate until such time as the total amount
of interest accrued on the unpaid principal amount of the Loan equals the amount
of interest  that would have  accrued if such  applicable  rate had at all times
been in effect.

      Section 3.2. Maximum  Interest.  It is the intention of the parties hereto
to conform  strictly to the usury Laws in force that apply to this  transaction.
Accordingly,  all  agreements  among  the  parties  hereto  (including,  without
limitation,  the Loan Documents),  whether now existing or hereafter arising and
whether written or oral, are hereby limited so that in no  contingency,  whether
by reason of  acceleration  of the maturity of the Loan or otherwise,  shall the
interest  (and all other sums that are deemed to be  interest)  contracted  for,
charged or received by Lender with respect to the Loan and the Note,  exceed the
Highest Lawful Rate. If, from any  circumstance  whatsoever,  interest under the
Loan and/or the Note would  otherwise be payable in excess of the Highest Lawful
Rate, and if from any  circumstance  Lender shall ever receive anything of value
deemed  interest by applicable  Law in excess of the Highest  Lawful Rate,  then
Lender's  receipt of such excess interest shall be deemed a mistake and the same
shall,  so long as no Event of  Default  shall be  continuing,  at the option of
Borrower,  either be repaid to Borrower  or  credited  to the unpaid  principal;
provided,  however,  that if an Event of  Default  shall  have  occurred  and be
continuing,  and Lender shall receive excess interest  during such period,  then
Lender shall have the option of either crediting such excess amount to principal
or  refunding  such  excess  amount to  Borrower.  If the Loan is prepaid or the
maturity of the Loan is  accelerated  by reason of an  election of Lender,  then
unearned  interest,  if any, shall be canceled and, if theretofore  paid,  shall
either be refunded to  Borrower or credited on the Loan,  as the Lender  elects.
All interest paid or agreed to be paid to Lender shall, to the extent allowed by
applicable Law, be amortized,  prorated,  allocated,  and spread  throughout the
full period until payment in full of the principal  (including the period of any
renewal or extension) so that the interest for such full period shall not exceed
the Highest Lawful Rate. Notwithstanding that the

                                       34

<PAGE>



parties  hereto in good faith deem each and every fee provided by this Agreement
to be a bona fide fee for  services  rendered  and to be rendered  separate  and
apart from the lending of money or the  provision of credit,  if any such fee is
ever  determined  by a Tribunal or by Lender to  constitute  interest,  then the
treatment of such fee for usury  purposes  shall be controlled by the provisions
of this Section 3.2

      Section 3.3.  Interest after Default.  Subject to Section 3.2 above,  past
due principal,  interest, fees, expenses and other sums due Lender from Borrower
shall accrue interest at the Default Rate until paid.


                                   ARTICLE 4.

                                     PAYMENT

      Section 4.1. Payment. All payments and prepayments of principal,  interest
and other  charges or fees  hereunder  shall be made in lawful  currency  of the
United  States of  America  in  immediately  available  funds,  without  setoff,
counterclaim  or deduction  of any kind.  Funds  received  later than 10:00 a.m.
Dallas,  Texas  time  shall be  deemed to have  been  received  by Lender on the
following  Business Day.  Notwithstanding  the foregoing,  all items of payment,
solely for the purpose of  determination  of a Potential  Event of Default or an
Event of Default,  shall be deemed received upon actual receipt by Lender unless
the same is subsequently dishonored for any reason.

      Section 4.2 Place of Payment.  All payments and  prepayments of principal,
interest and other  charges  hereunder to Lender shall be made at the  principal
office of Lender in Dallas,  Texas or at such  other  location  as Lender  shall
direct or upon Lender's request in accordance with Section 2.10 hereof.

      Section 4.3 Payment Due on Non-Business  Days. If any payment of principal
or interest on the Note, or if any other payment or fee provided for in the Loan

document,  certificate or written statement  furnished to Lender by or on behalf
of  Borrower  or the  Guarantor  in  connection  herewith  contains  any  untrue
statement of a material  fact or omits to state any material  fact  necessary in
order to make the statements  contained herein or therein not misleading.  There
is no fact peculiar to Borrower or Guarantor which materially  adversely affects

agreement,  license,  mortgage,  deed of trust or any other material  agreement,

before  or by any  governmental  authority  or  instrumentality  or  before  any

there is no  valid  basis  for any such  action,  proceeding  or  investigation.
Neither  Borrower nor the  Guarantor is subject to any  judgment,  order,  writ,
injunction  or  decree  of any  court  or  governmental  agency.  There is not a
reasonable  likelihood  of an adverse  determination  of any pending  proceeding
which

                                       40

<PAGE>



would,  individually or in the aggregate,  have a material adverse effect on the
business operations or financial condition of Borrower.

         Section 6.11.  Liabilities.  Neither Borrower nor the Guarantor has any
contingent or direct liabilities or unrealized or unanticipated  losses which in

required by law to be filed have been filed and all taxes  imposed upon Borrower
and the  Guarantor or their  respective  properties,  which are due and payable,
have been paid;  and no  amounts  of taxes not  reflected  on such  returns  are
payable by Borrower or the  Guarantor  other than taxes as are being  diligently
contested  in good  faith  by  appropriate  legal  proceedings  and as to  which
adequate reserves (determined in accordance with GAAP) have been provided,  none
of which,  individually or collectively,  will have a material adverse effect on
the financial condition or business operation of Borrower or the Guarantor.

         Section 6.13.  ERISA.

                  (a)  Schedule  6.13  attached  hereto  lists each Plan that is
         maintained,  administered  or  contributed  to for the  benefit  of the
         employees of Borrower.

                  (b) Except as otherwise  identified  in Schedule 6.13 attached
         hereto,  no Plan  constitutes  a  "Multi-Employer  Plan" as  defined in
         Section 3(37) of ERISA (a "Multi- Employer Plan").

                  (c) Neither  Borrower has incurred any  withdrawal  liability,
         which has not been satisfied, to any Multi-Employer Plan.

                  (d) Each Plan has been  maintained in  substantial  compliance
         with its  terms  and with its  requirements  prescribed  by any and all
         statutes,  orders, rules and regulations,  including but not limited to
         ERISA and the Code, which are applicable to such Plan.

                  (e) The funding method used in connection with each Plan which
         is subject to the minimum  funding  requirements of ERISA is acceptable
         and the actuarial assumptions used in connection with funding each such
         Plan are  reasonable.  The assets of each such Plan are  sufficient  to
         discharge all liabilities under such Plan, on an ongoing basis and on a
         termination basis, and there is no "accumulated funding deficiency," as
         defined in Section 302(a)(2) of ERISA, with respect to any plan year of
         any such Plan.  There is no basis for the PBGC or a court to  terminate
         any Plan  which is  covered  by Title IV of ERISA  and no such Plan has
         ever obtained a minimum funding waiver.

                  (f) With respect to each Plan, no prohibited  transaction  (as
         defined  in  Section  406 of ERISA or  Section  4975 of the  Code)  has
         occurred which would, directly or indirectly,

                                       41

<PAGE>



         result in any liability of Borrower,  no Reportable  Event has occurred
         and no claims  exist  against  such a Plan or its  assets,  other  than
         claims benefits in the ordinary course.

         Section 6.14.  Compliance with Laws.  Neither Borrower or the Guarantor
is in violation of any laws, rules, regulations,  orders, and decrees applicable
to the Borrower or the Guarantor.

         Section 6.15.  Subsidiaries.  Borrower has no Subsidiaries.

         Section 6.16.  Capital  Structure.  Borrower's  authorized,  issued and
outstanding  capital stock is as described in Schedule 6.16 attached hereto. All
of such issued and outstanding  shares are duly  authorized,  validly issued and
fully paid and have not been issued in  violation of any  preemptive  or similar
rights.  Borrower does not have  outstanding any securities  convertible into or
exchangeable  for its  capital  stock,  nor any  rights to  subscribe  for or to
purchase,  any options for the purchase of, or any agreements  providing for the
issuance  (contingent or otherwise)  of, or any calls,  commitments or claims of
any character  relating to, its capital stock or securities  convertible into or
exchangeable for its capital stock.

         Section 6.17.  Judgments.  There are no material  outstanding or unpaid
judgments  that have been  outstanding  for more  than  five (5)  Business  Days
against Borrower or the Guarantor that have not been adequately bonded.  Neither
Borrower  or  the  Guarantor  is a  party  to any  reorganization,  arrangement,
composition, readjustment, dissolution, rehabilitation,  liquidation, or similar
proceeding under any provision of any Law, or has consented to the filing of any
petition against it under any such Law.

connection  with this Agreement  violate any provision of the securities laws of
the United States,  including the  Securities  Act of 1934, as amended,  and the
rules  and  regulations   promulgated  thereunder  by  the  Securities  Exchange
Commission,  or the  securities  and  "blue  sky"  laws of the  various  states.
Borrower has not, nor has any Person  acting or  purporting  to act on behalf of
Borrower,  directly or indirectly,  offered the Note for sale to,  solicited any
offer to buy the Note from,  otherwise  negotiated  in respect  thereof with any
Person,  or done (or omitted to do) any other act so as to bring the issuance or
sale  thereof  tot  he  Lender  within  the  registration  requirements  of  the
Securities  Act of 1933,  as amended.  Borrower has complied  with or are exempt

various states applicable to the issuance or sale of the Note to the Lender.

disputes (a) pending or (b) to the best knowledge of Borrower and the Guarantor,
threatened  or  anticipated  between  Borrower  and any group or groups of their

                         EVENTS OF DEFAULT AND REMEDIES

         Section 9.1.  Nature of Event.  An Event of Default shall exist if any 
of the following occurs and is continuing:

                  (a) Principal and Interest. Borrower fails to make any payment
         or  prepayment  of principal  and/or  interest on the Note when due and
         payable,  and such failure  continues  for five (5) days after  written
         notice thereof is given by Lender to Borrower;

                  (b)  Fees.  Borrower  fails to pay  when due any fee  required
         hereunder or any other payment (other than the payments  referred to in
         Sections  9.1(a) above  required by the Loan Documents and such failure
         continues  for ten (10) days after written  notice  thereof is given by
         Lender to Borrower;

                  (c) Loan  Documents.  Borrower or Guarantor fail to perform or
         to observe any covenant or agreement  contained herein or in any of the

         days after written notice thereof being given by Lender to Borrower;

         instrument  and such  failure is not remedied  within  thirty (30) days
         after written notice thereof given by Lender to Borrower;




                  (e)  Representations  and Warranties.  Any  representation  or
         warranty  previously,  presently or  hereafter  made by or on behalf of

                  (f) Debt. Borrower (i) fails to duly pay when the same becomes

         breach or default, with notice or the passage of time, or both,  allows
         the maturity of such Debt to be accelerated;

         thirty (30) days of its initiation;

                  (i)  Assignment  for  Benefit of  Creditors.  Borrower  or the
         Guarantor  (i)  makes  a  general  assignment  for the  benefit  of its
         creditors,  (ii)  admits  in  writing  its  inability  to pay its debts
         generally as they become due, (iii) generally fails to pay its debts as
         they  become  due,  (iv)  consents  to the  appointment  of a receiver,
         trustee  or  liquidator  of all  or any  part  of  its  assets,  or (v)
         otherwise commits any similar act;

                  (j) Judgments.  Any judgment, writ or warrant of attachment or
         any  similar  process  is  entered  or filed  against  Borrower  or the
         Guarantor  or  any of  their  assets  and  remains  unpaid,  unvacated,
         unbonded or unstayed for thirty (30) days or for at least ten (10) days
         prior to the date on which such assets may be lawfully  sold to satisfy
         such judgment, writ or warrant;

                  (k) ERISA.  Lender  determines that (i) any ERISA Affiliate of

         requirements  of Section 412 of ERISA,  with respect to any Plan,  (ii)
         any ERISA  Affiliate  of Borrower  has a material  liability to PBGC or

         to any ERISA Affiliate of Borrower; or

                  (l)  Enforceability  of  Loan  Documents.   Any  of  the  Loan
         Documents  shall,  in whole or in part,  (i) cease to be legal,  valid,
         binding agreements  enforceable  against any Person executing the same,
         (ii) in any way be terminated or become or be declared  ineffective  or

         provide the  respective  Liens,  rights,  titles,  interest,  remedies,
         powers or privileges intended to be created thereby.

         Notwithstanding   any  other   provision   relating   to  notices   and
         opportunities  to remedy  defaults  contained in this  Agreement,  if a
         Potential  Event of  Default  exists  because  of a  willful  breach by
         Borrower or the Guarantor of any  representation,  warranty or covenant
         contained in this  Agreement or in any of the other Loan  Documents and
         if such Potential Event of Default would adversely affect the rights of
         Lender in relation  to other  creditors  of  Borrower or the  Guarantor
         prior to  expiration  of the cure  period for such  Potential  Event of
         Default, then Lender may exercise the remedies set forth in Section 9.2
         without  giving  such  notice and  opportunity  to remedy such event or
         condition.

         is sought,  Lender  shall have,  in  addition  to all other  rights and
         remedies  provided for herein or otherwise  available to it, the rights
         and remedies of a secured party under the Uniform  Commercial  Code, as
         amended, in the applicable jurisdiction

                  (c) Lender may, at its option,  without notice or demand, take
         immediate  possession of the  Collateral,  and for that purpose  Lender
         may, so far as Borrower  can give  authority  therefor,  enter upon any
         premises on which any of the Collateral is situated and remove the same
         therefrom  or  remain  on  such  premises  and in  possession  of  such
         Collateral for purposes of conducting a sale or enforcing the rights of
         Lender under this  Agreement.  Borrower  will,  upon  demand,  make the
         Collateral available to Lender at a place and time designated by Lender
         which is  reasonably  convenient  to Lender  and  Borrower.  Lender may
         collect  and  receive  all  income  and  proceeds  in  respect  to  the
         Collateral  and may apply the  Collateral  and any and all  income  and
         proceeds in respect of the Collateral to the payment of all obligations
         of Borrower to Lender.

                  (d)  Lender  may  sell,  lease  or  otherwise  dispose  of the
         Collateral  at a public or private  sale or sales,  in lots or in bulk,
         for cash or on credit,  with or without  having the  Collateral  at the
         place  of  sale,  and upon  terms  and in such  manner  as  Lender  may
         determine in accordance  with  applicable  Law, and Lender may purchase
         any Collateral at any such sale. The  requirement of reasonable  notice
         to Borrower of the time and place of any public sale of the  Collateral
         or of the time after which any private  sale either by Lender or at its
         option,  through a broker, or any other intended disposition thereof is
         to be made, shall be met if such notice is mailed,  postage prepaid, to
         Borrower at the address of Borrower designated herein at least ten (10)
         days  before  the date of any  public  sale or at least  ten (10)  days
         before the time after which any private sale or other disposition is to
         be  made.  Lender  shall  not be  obligated  to  make  any  sale of the
         Collateral  regardless of notice of sale having been given.  Lender may
         adjourn any public or private sale without further  notice,  be made at
         the time and place to which it was so adjourned.  Upon any such sale or
         sales  the  Collateral  so  purchased  shall  be held by the  purchaser
         absolutely free from any claims or rights of whatsoever kind or nature,
         including any equity of  redemption  and any similar  rights,  all such
         equity of  redemption  and any similar  rights being  hereby  expressly
         waived and released by Borrower. In the event any consent,  approval or
         authorization  of  any   governmental   agency  will  be  necessary  to
         effectuate  any such sale or sales,  Borrower  shall  execute  all such
         applications or other instruments as may be required.

                  (e) Prior to any  disposition  of Collateral  pursuant to this
         Agreement, Lender may, at its option, cause any of the Collateral to be
         repaired or  reconditioned in such manner and to such extent as to make
         it saleable,  and any reasonable sums expended therefor by Lender shall
         be repaid by Borrower and become part of the Indebtedness.

                  (f) In  addition  to  the  remedies  provided  for  herein  or
         otherwise  available to Lender,  Lender is hereby  granted a license or
         other  right  to  use,  without  charge,  Borrower's  labels,  patents,
         copyrights,  rights of use in any name,  trade  secrets,  trade styles,
         trade names,  trademarks and advertising  matter,  or any property of a
         similar  nature,  as it  pertains  to  the  Collateral,  in  completing
         production  of  advertising  for sale and selling any  Collateral,  and
         Borrower's  rights under all licenses and  franchise  agreements  shall
         inure to Lender's  benefit.  Lender shall have the right to sell, lease
         or otherwise dispose of the Collateral,  or any part thereof, for cash,
         credit or any combination  thereof, and Lender may purchase all or part
         of the Collateral at public or, if permitted by law,  private sale and,
         in lieu of  actual  payment  of such  purchase  price,  may set off the
         amount of such price  against  the  Indebtedness  owing to Lender.  The
         proceeds  realized  from the sale of any  Collateral  shall be  applied
         first  to the  reasonable  costs,  expenses  and  attorney's  fees  and
         expenses incurred by Lender for collection and acquisition, completion,
         protection,  removal,  storage,  sale and  delivery of the  Collateral;
         second,  to interest due upon any of the  Indebtedness;  third,  to the
         principal balance owing on the Indebtedness; and the remainder, if any,
         to  Borrower.  If any  deficiency  shall arise,  Borrower  shall remain
         liable to Lender therefor.

                  (g) The right to  contact  Account  Debtors  of  Borrower  and
         demand that payment on any  Receivables be made directly to Lender,  if
         Lender holds a first and superior lien on such Receivables.

                  (h) The right to appoint or seek  appointment  of a  receiver,
         custodian or trustee of Borrower or any of its assets pursuant to court
         order.

                  (i) Exercise  any and all rights and remedies  afforded by the
         Laws of any applicable jurisdiction, the Loan Documents or as otherwise
         afforded by any Laws or equity.

                  (j)  Exercise  any rights of setoff that Lender may have under
         applicable  Law  against  each and every  account  and other  property,
         Collateral  or other asset of Borrower in the  possession  or under the
         control of Lender.

         Section 9.3.  Application of Proceeds.  All amounts  realized by Lender
with respect to the Indebtedness, including amounts realized with respect to the
Collateral  under or by virtue of the Loan  Documents,  including any sums which
may be held by Lender,  or the  proceeds  of any  thereof,  shall be applied (i)
first,  to the  payment of the costs and  expenses  owing under  Section  7.1(i)
hereof  or  under  any  of  the  other  Loan  Documents,   including  reasonable
compensation  to  Lender  and  its  agents  and  attorneys,   of  all  expenses,
liabilities and advances made or furnished or incurred by or on behalf of Lender
under this Agreement or any Loan Document or any amendment to,  restructuring or
"workout" of same; (ii) second,  to the payment of any other sums due to Lender,
or any  successors  or  assigns  thereof,  pursuant  to the  terms  of any  Loan
Document, except for principal of and accrued

                                       57

<PAGE>



and unpaid  interest  on the Note;  (iii)  third,  to the payment of accrued and
unpaid  interest on and the outstanding  principal of the Note; (iv) fourth,  to
the  payment  of the  outstanding  principal  of the Note;  and (v)  fifth,  the
surplus,  if any,  to  Borrower,  or to whomever  shall be lawfully  entitled to
receive the same, as a court of competent jurisdiction may direct.

         Section  9.4.  Performance  by  Lender.  Should any  covenant,  duty or
agreement of Borrower fail to be performed in  accordance  with the terms of the
Loan  Documents,  Lender may,  at its  option,  perform or attempt to perform or
enforce such  covenant,  duty or  agreement  on behalf of Borrower.  All amounts
expended in connection therewith, together with interest from the date incurred,
shall become a part of the Indebtedness.  Notwithstanding  the foregoing,  it is
expressly understood that Lender does not assume any liability or responsibility
for the  performance  of any duties of  Borrower  hereunder  or under any of the
other  Loan  Documents  or other  control  over the  management  and  affairs of
Borrower.

         Section 9.5.  Cumulative  Rights.  All rights and remedies available to
Lender  hereunder and under the other Loan Documents  shall be cumulative of and
in  addition  to all other  rights and  remedies  granted to Lender at Law or in
equity,  whether or not the  Indebtedness  (or any  portion  thereof) is due and
payable  and  whether  or not  Lender has  instituted  any suit for  collection,
foreclosure or any other action in connection with the Loan Documents.

         Section 9.6. General Indemnity.  Borrower promises to indemnify Lender,
upon  demand,  from and against any and all  liabilities,  obligations,  claims,
losses,  damages,  penalties,  actions,  judgments,  suits,  costs,  expenses or
disbursements of any kind or nature whatsoever which may be imposed on, incurred
by, or asserted against Lender or any of its directors, officers or employees or
agents  (including,  accountants,  attorneys  and other  professionals  hired by
Lender)  (whether or not caused by any  negligent act or omission of any kind by
Lender) growing out of or resulting from the Loan Documents and the transactions
and events at any time associated  therewith  (including  without limitation the
enforcement  of the Loan  Documents  and the  defense of  Lender's  actions  and
inactions in connection with the Loan).

         Section  9.7.  Environmental  Indemnity by  Borrower.  Borrower  hereby
indemnifies and agrees to hold Lender,  its directors,  officers,  and employees
(collectively  the   "Indemnitee")   harmless  from  and  against  any  and  all
Environmental Costs arising in any manner in connection with:

                  (a) Any  Environmental  Condition in existence at any property
         (the "Controlled  Property") now or formerly owned, leased, or operated
         by  Borrower;  the  occurrence,  at any  time  during  or  prior to the
         ownership,   tenancy,  or  operation  of  the  Controlled  Property  by
         Borrower, of any Environmental  Activity; or any failure of Borrower or
         any  third   party  to  comply   with  all   applicable   Environmental
         Requirements relating to the Controlled Property;

                  (b) Any failure of any representation or warranty set forth in
         Article  6 to be  correct  in all  respects  as of  the  date  of  this
         Agreement  or  any  subsequent  date  during  the  term  hereof  or any
         extensions  thereto and a breach of any of the  covenants  contained in
         this Agreement.

                  (c) The transportation  to, disposal at, or  migration onto or
         into adjacent property

                                       58

<PAGE>



         or any off-site location of any Hazardous Materials from any Controlled
         Property  as a result of  Environmental  Activity  or an  Environmental
         Condition  that  occurred or existed  during or prior to the use of the
         Controlled  Property by Borrower,  whether or not the transportation or
         disposal  was   conducted  in  full   compliance   with   Environmental
         Requirements;

                  (d) Any  claim,  demand or cause of  action,  or any action or
         other proceeding, including any investigation, inquiry, order, hearing,
         action by or before any Tribunal,  whether  meritorious or not, brought
         or  asserted  against  Indemnitee  which is alleged to or  directly  or
         indirectly  relates  to,  arises from or is based on any of the matters
         described in clauses (a) through (c) of this Section 9.7.

                  (e) The  obligations  of this  Section  9.7 shall  include the
         obligation  to  defend  Indemnitee  against  any  claim or  demand  for
         Environmental   Costs,   the   obligation  to  pay  and  discharge  any
         Environmental  Costs  imposed  on  Indemnitee,  and the  obligation  to
         reimburse  Indemnitee for any Environmental  Costs incurred or suffered
         by   Indemnitee,   provided  in  each   instance  that  the  claim  for
         Environmental  Costs  arises  in  connection  with a matter  for  which
         Indemnitee is entitled to  indemnification  under this  Agreement.  The
         scope  of  this  indemnification  shall  also  include  indemnification
         against  Environmental Costs whether or not they are caused in whole or
         in part  by the  negligence  of  Indemnitee.  This  Section  9.7  shall
         expressly  survive the full payment of the Note, any  foreclosure(s) on
         the Collateral, and/or the termination of this Agreement.

         Section 9.8. Borrower's Remedies.  No action, suit or proceeding may be
initiated or commended by Borrower or Guarantor  against  Lender under the terms
of this  Agreement or by reason of any conduct or omission in any way related to
this Agreement  unless Lender receives written notice from Borrower or Guarantor
specifically setting forth the claim of Borrower or Guarantor within one hundred
eighty (180) days after Borrower or Guarantor discover or should have discovered
the event or  occurrence  which  Borrower or Guarantor  assert gave rise to such
claim.  Moreover,  in any event,  Lender  shall  never be liable to  Borrower or
Guarantor for  consequential  or exemplary  damages,  whatever the nature of the
alleged breach by the Lender of the obligations of Lender hereunder.

                                   ARTICLE 10.

                                  MISCELLANEOUS

         Section 10.1.  Waiver and  Amendment.  No failure or delay by Lender in
exercising  any right,  power or remedy  under any of the Loan  Documents  shall
operate as a waiver  thereof or of any other right,  power or remedy,  nor shall
any  single or partial  exercise  by Lender of any such  right,  power or remedy
preclude any other or further exercise  thereof or of any other right,  power or
remedy.  No waiver of any  provision of any Loan  Document and no consent to any
departure  therefrom shall ever be effective  unless it is in writing and signed
by  Lender,  and then such  waiver or  consent  shall be  effective  only in the
specific  instances  and for the  purposes  for which  given  and to the  extent
specified  in such  writing.  No notice to or demand on Borrower  shall  entitle
Borrower  to any  other  or  further  notice  or  demand  in  similar  or  other
circumstances. No modification, amendment or supplement to this Agreement or the
other Loan Documents shall be valid or effective

                                       59

<PAGE>



unless the same is in writing and signed by the party  against whom it is sought
to be enforced.  The acceptance by Lender at any time and from time to time of a
partial  payment of the  Indebtedness  shall not be deemed to be a waiver of any
Event of  Default  then  existing.  No waiver by Lender of any Event of  Default
shall be deemed to be a waiver of any other then existing or subsequent Event of
Default.

         Section   10.2.   Survival   of   Agreements.   All  of   the   various
representations,  warranties,  covenants and  agreements  in the Loan  Documents
shall survive the  execution  and delivery of this  Agreement and the other Loan
Documents and performance  hereof and thereof,  including without limitation the
making or granting of the  security  interests  and the delivery of the Note and
the  other  Loan  Documents,   and  shall  further  survive  until  all  of  the
Indebtedness  is paid  in full to  Lender  and all of  Lender's  obligations  to
Borrower are terminated.

         Section 10.3. Release. By execution of this Agreement,  Borrower hereby
releases,   waives,   discharges  and  relinquishes   Lender,   his  Affiliates,
representatives,  attorneys,  agents, heirs and assigns from any and all claims,
demands,  charges  or causes of  action,  now  existing  or  hereafter  arising,
relating to or arising  from the  discussion,  negotiation  or execution of this
Agreement,  the Loan  Documents,  any  other  document  executed  in  connection
herewith or  therewith,  or from any of the  transactions  contemplated  hereby,
which claims, demands, charges or causes of action are hereby released,  waived,
discharged and relinquished by Borrower to the extent that such claims, demands,
charges and causes of action may be validly  released or waived under applicable
law,  it being  hereby  understood  by the  parties  hereto that the release and
waiver in favor of Lender set forth herein shall not extend to any claim, demand
or cause of action the waiver of which by Borrower is  expressly  prohibited  by
applicable  state or federal law.  Notwithstanding  the foregoing,  this Release
shall  not be  applicable  to  any  term,  representation,  covenants  or  other
provision of this Stock Purchase Agreement.

         Section 10.4.  Relief in  Bankruptcy.  Borrower  hereby agrees that, in
consideration of the recitals and mutual  covenants  contained  herein,  and for
other good and valuable consideration, in the event Borrower shall (i) file with
any bankruptcy court of competent jurisdiction or be the subject of any petition
under Title 11 of the U.S.  Code,  as amended,  (ii) be the subject of any order
for relief issued under such Title 11 of the U.S.  Code, as amended,  (iii) file
or be the  subject of any  petition  seeking any  reorganization  rearrangement,
composition,  adjustment, liquidation,  dissolution, or similar relief under any
present or future state act or law relating to  bankruptcy,  insolvency or other
relief for  debtors,  (iv) have  sought or  consented  to or  acquiesced  to any
appointment of any trustee,  receiver,  conservator,  or liquidator,  (v) be the
subject  of any order,  judgment  or decree  entered  by any court of  competent
jurisdiction   approving   a   petition   filed   against   such  part  for  any
reorganization,    rearrangement,    composition,    adjustment,    liquidation,
dissolution,  or similar relief under any present or future federal or state act
of law relating to  bankruptcy,  insolvency or relief for debtors,  Lender shall
thereupon be entitled to relief from the  automatic  stay imposed by Section 362
of Title 11 of the U.S.  Code,  as  amended,  or  otherwise,  on or against  the
exercise of the rights and  remedies  otherwise  available to Lender as provided
herein,  in the Loan  Documents,  any other  document or instrument  executed in
connection herewith or therewith,  and as otherwise provided by applicable state
and federal law.

         Section 10.5.  No  Obligation  Beyond  Maturity.  Borrower  agrees  and
acknowledges that upon

                                       60

modify or rearrange the Loan and shall have the right to require all amounts due
and owing under the Loan to be paid in full upon the maturity thereof.

         Section 10.6. Notices.  All notices,  requests,  consents,  demands and
other  communications  required or permitted under any Loan Document shall be in
writing and, unless otherwise specifically provided in such Loan Document, shall
be deemed sufficiently given or furnished if delivered by personal delivery,  by
telecopy or telex, by expedited  delivery service with proof of delivery,  or by

attempted  delivery at the address and in the manner provided herein,  or in the
case of delivery service or mail, as of the date of first attempted  delivery at

                  been executed and  delivered  pursuant to, and is governed by,

                  hereunder, may be declared due prior to the expressed maturity
                  date hereof as provided in the  Agreement,  reference to which
                  is hereby made for a complete statement of the terms thereof.

         2.       Principal and  Interest.  Principal  prepayments  and interest
                  payments   shall  be  due  and  payable  as  provided  in  the
                  Agreement;  provided, however, that the interest payable shall
                  not exceed the Highest Lawful Rate.

         3.       Waiver.  Borrower, and  each surety,  endorser, guarantor  and

                  other party now or  hereafter  liable for the  payment of  any
                  sums of money  payable  on this  Note,  hereby  severally  (a)
                  waive demand, presentment for  payment, notice  of nonpayment,
                  protest,  notice  of protest, notice of  intent to accelerate,
                  notice of acceleration and  all other notices, filing  of suit
                  and diligence  in collecting this Note  or enforcing any other
                  security   with   respect   to   same,   (b)   agree   to  any
                  substitution, subordination,  exchange or  release of any such
                  security  or    the  release  of  any  parties   primarily  or
                  secondarily  liable hereon,  (c) agree that  Lender shall  not
                  be required  first  to institute  suit or exhaust its remedies
                  hereon  against  Borrower,  or  others  liable  or  to  become
                  liable  hereon or to  enforce its rights  against them or  any
                  security  with  respect to  same,  (d) consent to any  and all
                  renewals,  extensions,   indulgences,  releases  or   changes,
                  regardless  of  the  number  of  such   renewals,  extensions,
                  indulgences, releases or

                                       67

<PAGE>



                  changes,   without  notice  hereof,   and  (e)  agree  to  the
                  application  of any deposit  balance with Lender as payment or
                  part  payment  hereon  or as an  offset  hereto.  No waiver by
                  Lender of any of its rights or remedies hereunder or under any
                  other  document  evidencing or securing this Note or otherwise
                  shall be considered a waiver of any other  subsequent right or
                  remedy of Lender;  no delay or  omission  in the  exercise  or
                  endorsement  by Lender of any rights or remedies shall ever by
                  construed as a waiver of the same or any other right or remedy
                  of Lender; and no exercise or enforcement of any such right or
                  remedy  shall ever be held to  exhaust  any right or remedy of
                  Lender.

         4.       Event of Default.  Failure to pay this Note or any installment
                  of  principal  or payment of interest  when due in  accordance
                  with the terms of this Note or the Agreement or the occurrence
                  of any Event of Default  shall,  as provided in the Agreement,
                  mature this Note and the principal then remaining unpaid, with
                  interest then accrued, shall at once become due and payable.

         5.       Attorney's  Fees and Cost of  Collection.  If this Note is not
                  paid at maturity and is placed in the hands of an attorney for
                  collection,  or if it is collected through a bankruptcy or any
                  other  court,  then Lender  shall be  entitled  to  reasonable
                  attorneys' fees and other costs of collection.

         6.       Limitation on Interest.  Borrower acknowledges and agrees that
                  it  is  the  intention  of  the  parties  hereto   to  conform
                  strictly  to the  usury  Laws in  force  that  apply  to  this
                  transaction.  Accordingly,  this  Note is  hereby  limited  so
                  that in no contingency, whether  by reason  of acceleration of
                  the  maturity  of  the Loan or  otherwise,  shall the interest
                  (and  all   other  sums  that  are  deemed  to   be  interest)
                  contracted  for,  charged  or received  by Lender with respect
                  to the Loan and the Note exceed the Highest  Lawful Rate.  If,
                  from  any  circumstance  whatsoever,  interest under the  Loan
                  and/or the Note  would  otherwise  be payable in excess of the
                  Highest  Lawful  Rate,  and  if from any  circumstance  Lender
                  shall ever  receive  anything  of  value  deemed  interest  by
                  applicable  Law in excess of the  Highest  Lawful  Rate,  then
                  Lender's  receipt of such excess  interest  shall  be deemed a
                  mistake and the same  shall,  so long as no  Event  of Default
                  shall be  continuing,  at the option of  Borrower,  either  be
                  repaid to  Borrower  or  credited  to the unpaid  principal;
                  provided,  however,  that if an Event of  Default  shall  have
                  occurred and be continuing,  and Lender shall  receive  excess
                  interest  during such  period,  then  Lender  shall  have  the
                  option of either  crediting  such  excess  amount to principal
                  or refunding such excess amount for Borrower.  If the Loan  is
                  prepaid or the maturity of the Loan is  accelerated by  reason
                  of an election of Lender,  then  unearned  interest,  if  any,
                  shall be canceled  and, if theretofore  paid, shall  either be
                  refunded to  Borrower  or  credited  on  the Loan,  as  Lender
                  elects.  All  interest  paid or  agreed to  be  paid to Lender
                  shall,   to  the   extent  allowed  by   applicable   Law,  be
                  amortized,  prorated,  allocated,  and  spread throughout  the
                  full period until  payment in  full  of  principal  (including
                  the period of any renewal or extension) so  that the  interest
                  for such full  period  shall  not  exceed the  Highest  Lawful
                  Rate.

                  AND INSTRUMENT MADE UNDER THE LAWS OF THE STATE OF TEXAS AND
                  SHALL BE  CONSTRUED  AND  ENFORCED  IN  ACCORDANCE  WITH AND

                  STATE AND  FEDERAL  COURTS OF THE STATE OF TEXAS AND  AGREES
                  AND CONSENTS  THAT SERVICE OF PROCESS MAY BE MADE UPON IT IN
                  ANY LEGAL  PROCEEDING  RELATING TO THE LOAN DOCUMENTS OR THE
                  OBLIGATIONS BY ANY MEANS ALLOWED UNDER TEXAS OR FEDERAL LAW.
                  VENUE FOR ANY LEGAL PROCEEDING MAY BE DALLAS COUNTY,  TEXAS;
                  PROVIDED,  THAT  LENDER  MAY  CHOOSE  ANY VENUE IN ANY STATE
                  WHICH  IT  DEEMS  APPROPRIATE  IN THE  EXERCISE  OF ITS SOLE
                  DISCRETION.

         8.       WAIVER OF JURY TRIAL.  BORROWER AND LENDER EACH HEREBY WAIVE
                  ANY  RIGHT TO TRIAL BY JURY OF ANY  CLAIM,  DEMAND,  ACTION,
                  CAUSE OF ACTION,  SUIT OR PROCEEDINGS (a) ARISING UNDER THIS

                  EXECUTED OR DELIVERED IN  CONNECTION  HEREWITH OR (b) IN ANY
                  WAY  CONNECTED  WITH  OR  RELATED  TO OR  INCIDENTAL  TO THE

                                      NOTE

         (1) FOR VALUE RECEIVED,  the undersigned PHY.MED.,  INC. EMPLOYEE STOCK
OWNERSHIP  PLAN  ("Maker"),  hereby  promises  to pay to the order of Patrick A.
Luckett  ("Payee"),  at c/o John Dee Evans,  Hoge,  Evans & Holmes,  L.C., 17772
Preston Road,  First Floor,  Dallas,  Texas 75252, in lawful money of the United
States of  America,  the  principal  sum of EIGHT  HUNDRED  THOUSAND  AND NO/100
DOLLARS  ($800,000.00),  together  with  interest on the  outstanding  principal
balance from day to day remaining as herein specified, as follows:

         (2) The  principal  and  interest of this Note shall be due and payable
pursuant to the  amortization  schedule set forth on Exhibit  "A",  beginning on
November 1, 1993, and monthly  installments shall be due and payable on the same
day of each  month  thereafter  with a final  payment  being due and  payable on
December 1, 2000,  at which time all remaining  principal and interest  shall be
paid.

         (3) The outstanding principal balance hereof shall bear interest at TEN
PERCENT (10%) per annum compounded monthly.  All past due principal and interest
shall bear  interest  at the rate of ten  percent  (10%) per  annum,  compounded
semi-annually.

         (4) Maker shall have the right to prepay,  at any time and from time to
time without  premium or penalty,  the entire unpaid  principal  balance of this
Note or any portion thereof, any such partial prepayments to be applied first to
accrued and unpaid  interest due as of the date of such partial  prepayment  and
any remaining amount to the outstanding principal hereof.

         (5) Notwithstanding anything herein to the contrary, this Note shall be
without recourse  against the Maker,  except as permitted by applicable law with
respect to a loan to a leveraged  employee  stock  ownership plan (as defined in
Section  4975(e)(7)  of the Internal  Revenue Code of 1986,  as amended).  Payee
shall not have any right to assets of Maker  other than (i) the  Collateral  [as
such term is defined in the  Security  (Pledge)  Agreement  executed  coincident
herewith (the "Security (Pledge)  Agreement")],  (ii) contributions  (other than
contributions of employer securities) that are made by or on behalf of PHY.MED.,
INC.  (the  "Employer")  to  enable  Maker  to meet  its  obligations  hereunder
("Contributions"),  and (iii)  earnings  attributable  to the Collateral and the
investment  of  such  Contributions.  Notwithstanding  anything  herein  to  the
contrary,  the amount of payments to be made hereunder  shall not exceed (a) the
sum of all cash Contributions theretofore received by Maker from the Employer to
meet the  obligations  hereunder and earnings  attributable to the investment of
such Contributions  less (b) all payments of principal and interest  theretofore
made by or on behalf of Maker hereon in prior years.

         (6) The  failure  of Maker to make a  payment  in  accordance  with the
provisions  of paragraphs  (2) or (3) of this Note shall  constitute an event of
default ("Event of Default") under this Note (notwithstanding the limitations of
the last  sentence  of  paragraph  (5) of this Note,  but will not result in the
acceleration of payments not yet due hereunder; provided, however, that an Event
of Default shall not occur hereunder until a payment required under this Note is
past-due by more than

                                       73

<PAGE>



fifteen (15) days after written notice of such default by Payee to Maker.  If an
Event of Default occurs, the rights and remedies of Payee or any other holder or
transferee  of this Note  shall be  limited to those  provided  in the  Security
(Pledge) Agreement, and

in no event can any  recovery  as a result  of an Event of  Default  exceed  the
dollar amount of such default.

         (7)  Notwithstanding  anything to the  contrary  contained  herein,  no
provisions  of this Note shall  require the payment or permit the  collection of
interest  in excess of the  Maximum  Rate.  If any  excess of  interest  in such
respect is herein  provided for, or shall be adjudicated  to be so provided,  in
this Note or otherwise in connection with this loan transaction,  the provisions
of this paragraph shall govern and prevail,  and neither Maker nor the sureties,
guarantors,  successors or assigns of Maker shall be obligated to pay the excess
amount of such interest,  or any other excess sum paid for the use, forbearances
or  detention  of sums loaned  pursuant  hereto.  If for any reason  interest in
excess  of the  Maximum  Rate  shall be  deemed  charged,  required,  permitted,
collected, or received by any court of competent  jurisdiction,  any such excess
shall be applied as a payment and  reduction of the  principal  of  indebtedness
evidenced by this Note;  and, if the  principal  amount hereof has been paid, in
full,  any remaining  excess shall  forthwith be paid to Maker.  Maximum Rate as
used herein shall mean the maximum rate permitted by applicable law.

         (8) This Note has been entered  into in Dallas  County,  Texas,  and it
shall be  performable  for all purposes in Dallas County,  Texas,  and Maker and
each surety, guarantor,  endorser and other party ever liable for payment of any
sums of money payable on this Note,  jointly or severally  waive the right to be
sued hereon elsewhere.  Courts within the State of Texas shall have jurisdiction
over any and all disputes arising under or pertaining to this Note; and venue in
any such  dispute  shall be laid in the county or  judicial  district of Payee's
principal  place of  business.  This Note shall be governed by and  construed in
accordance  with the laws of the State of Texas and the  applicable  laws of the
United States of America.

         (9) Maker and each  surety,  guarantor,  endorser  and other party ever
liable  for  payment  of any sums of money  payable  on this  Note  jointly  and
severally waive presentment and demand for payment,  protest,  notice of protest
and  non-payment or dishonor,  notice of  acceleration  or intent to accelerate,
diligence in collection, and grace, and consent to all extensions without notice
for any  period  or  periods  of time  and  partial  payments,  before  or after
maturity,  without prejudice to the holder.  The holder shall similarly have the
right to deal in any way, at any time, with one or more of the foregoing parties
without notice to any other party, and to grant any such party any extensions of
time for payment of any of said  indebtedness,  or to release part or all of the
collateral  securing this Note or to grant any other indulgences or forbearances

Lender in excess of the maximum  lawful amount,  the interest  payable to Lender
shall be reduced to the maximum amount  permitted under  applicable law; and, if
from any

                                       84

applicable law in excess of the maximum  lawful  amount,  an amount equal to any
excessive  interest  shall be applied to the  reduction of the  principal of the
indebtedness  guaranteed  hereby and not to the payment of interest,  or if such
excessive  interest  exceeds the unpaid balance of principal of the indebtedness
guaranteed   hereby  such  excess  shall  be  refunded  to  Guarantor  or  other
appropriate  party.  All interest paid or agreed to be paid to the Lender shall,
to the extent permitted by applicable law, be amortized, prorated, allocated and
spread  throughout the full period until payment in full of the principal of the
Indebtedness guaranteed hereby (including the period of any renewal or extension
thereof) so that  interest  thereon  for such full  period  shall not exceed the
maximum amount permitted by applicable law.

and nature  whatsoever.  Debtor  warrants and agrees that the Collateral will be

locations set forth in the  Schedule(s)  covering said  Collateral  and will not
make any change in the location of the  Collateral  within such state,  and will
not remove the Collateral  from such state without the prior written  consent of
Secured Party.

          after the due date until paid at the rate of  eighteen  percent  (18%)
          per annum.

         4. No  Warranties.  This  Agreement  is solely a  financing  agreement.
Debtor  acknowledges  that:  The  Collateral  has or will have been selected and
acquired  solely by  Debtor  for  Debtor's  purposes;  Secured  Party is not the
manufacturer, dealer, vendor or supplier of the Collateral; the Collateral is of
a size, design, capacity, description and manufacture selected by Debtor; Debtor
is  satisfied  that the  Collateral  is suitable and fit for its  purposes;  and
SECURED  PARTY  HAS NOT MADE AND DOES NOT MAKE ANY  WARRANTY  OR  REPRESENTATION
WHATSOEVER,   EITHER  EXPRESS  OR  IMPLIED,   AS  TO  THE  FITNESS,   CONDITION,
MERCHANTABILITY,  DESIGN OR  OPERATION  OF THE  COLLATERAL,  ITS FITNESS FOR ANY
PARTICULAR PURPOSE, THE VALUE OF THE COLLATERAL,  THE QUALITY OR CAPACITY OF THE
MATERIALS IN THE  COLLATERAL OR  WORKMANSHIP  IN THE  COLLATERAL,  NOR ANY OTHER
REPRESENTATION OR WARRANTY WHATSOEVER.

manufacturer,  Vendor, dealer or supplier, nor any salesman,  representative, or
other agent of the  manufacturer,  dealer,  vendor or  supplier,  is an agent of
Secured Party. No salesman, representative or agent of the manufacturer, dealer,
vendor or supplier is authorized to waive or alter any term or condition of this
Agreement, and no representation as to the Collateral or any other matter by any
manufacturer,  dealer,  vendor or supplier shall in any way affect Debtor's duty
to pay the Monthly Loan Repayment and perform his other obligations as set forth
in this Agreement.

         5.  Acceptance.  Execution by Debtor and Secured  Party of the Schedule
covering the Collateral  will  conclusively  establish that such  Collateral has
been  included  under and will be subject to all of the terms and  conditions of
this  Agreement.  If Debtor has not  furnished  Secured  Party with an  executed
Schedule  by the  earlier  of  fourteen  (14)  days  after  receipt  thereof  or
expiration of the  commitment set forth in any  applicable  Equipment  Financing
Commitment, Secured Party may terminate its obligation to make any Advances with
respect to any applicable Collateral.

         6.  Insurance  and Risk of Loss.  All risk of loss of,  damage  to,  or
destruction of the Collateral shall at all times be borne by Debtor. Debtor will
procure  forthwith and maintain  property and general  liability  insurance with
extended  or  combined  additional  coverage  on the  Collateral  for  the  full
insurable value thereof for the life of this Agreement and any Schedule(s)  plus
such other  insurance as Secured  Party may specify,  and promptly  deliver each
policy to Secured Party with a standard long form  endorsement  attached showing
Secured  Party or assigns as additional  insureds and loss payees.  Each insurer
shall  agree by  endorsement  upon such  policy  issued by it or by  independent
instrument furnished to Secured Party and Debtor that it will give Secured party
and Debtor thirty (30) days written  notice before the policy in question  shall
be materially  altered or canceled.  Secured  Party's  acceptance of policies in
lesser amounts or risks shall not be a waiver of Debtor's foregoing obligation.

warrants to Secured Party as follows:

               (a) Debtor is duly  organized and existing  under the laws of the

               (e) Secured Party may require  Debtor to assemble the  Collateral
          and return it to Secured  Party at a place to be designated by Secured
          Party which is reasonably convenient to both parties.

               (f)  Debtor  agrees  to pay the  Secured  Party all  expenses  or
          retaking,  holding,  preparing for sale, or selling the  Collateral in
          addition to attorneys' fees as set forth above.

         11. Acceleration Clause. In case of any sale of the Collateral,  or any
part  thereof,  pursuant to any  judgment or decree of any court or otherwise in
connection  with the  enforcement  of any of the  terms of this  Agreement,  the
outstanding  principal  due under  any  Schedule,  if not  previously  due,  the
interest  accrued  thereon  and all  other  sums  required  to be paid by Debtor
pursuant  to this  Agreement  shall at once  become and be  immediately  due and
payable.

         12.  Exercise of Rights.  No delay or omission of Secured  Party in the
exercise of any right or power arising from any default shall act as a waiver of
or impair any such right or power or prevent its exercise during the continuance
of such default.  No waiver by Secured  Party of any such default,  whether such
waiver be full or partial,  shall extend to or be taken to affect any subsequent
default,  nor shall it impair the rights  resulting  therefrom  except as may be
otherwise  provided therein.  The giving,  taking or enforcement of any other or
additional security, collateral, or

                                       94

guarantee  for the  payment  of the  Secured  Obligations  shall not  operate to
prejudice,  waive,  or affect the  security  of this  Agreement  or any  rights,
powers, or remedies  hereunder,  and Secured Party shall not be required to look
first to enforce  or exhaust  such other  additional  security,  collateral,  or
guarantees.  All rights, remedies, and options of Secured Party hereunder, or by
law shall be cumulative.

         13.  Assignment by Secured Party.  SECURED PARTY MAY ASSIGN OR TRANSFER
THIS AGREEMENT OR SECURED PARTY'S  INTEREST IN THE COLLATERAL  WITHOUT NOTICE TO
DEBTOR.  Any assignee of Secured  Party shall have all of the rights but none of
the obligations,  of Secured Party under this Agreement,  and Debtor agrees that
it  will  not  assert  against  any  assignee  of  Secured  Party  any  defense,
counterclaim or offset that Debtor may have against
Secured Party.

         14. Non-Terminable Agreement; Obligations Unconditional. This Agreement
cannot be canceled or terminated  except as expressly  provided  herein.  Debtor
hereby agrees that Debtor's  obligation to pay all Secured  Obligations shall be
absolute and  unconditional  and Debtor will not be entitled to any abatement of
Monthly  Loan  Repayments  or other  payments  due under this  Agreement  or any
reduction  thereof  under  circumstances  or for any reason  whatsoever.  Debtor
hereby waives any and all existing and future  claims,  as offsets,  against any
Monthly Loan  repayments and other payments due under this Agreement as and when
due  regardless of any offset or claim which may be asserted by Debtor or on its
behalf.  The obligations  and  liabilities of Debtor  hereunder will survive the
termination of this Agreement.

         15.  Additional  Documents.  In connection with and in order to provide
effective  evidence of the security  interest in the Collateral  granted Secured
Party under this  Agreement,  Debtor will  execute and deliver to Secured  Party
such  financing  statements  and similar  documents as Secured  Party  requests.
Debtor  authorizes  Secured Party where permitted by law to make filings of such
financing  statements  without  Debtor's  signature.  Debtor  further  agrees to

          including Debtor's most recent annual report, balance sheet and income

          principles,  which reports,  Debtor  warrants,  shall fully and fairly
          represent the true financial condition of Debtor;

               (b) any other financial  information  normally provided by Debtor
          to the public; and

               (c) Such other  financial  data or  information  relative to this
          Agreement and the Collateral, including, without limitation, copies of
          Suppliers'  proposals and purchase orders and agreements,  listings of

          information,  as  Secured  Party  may  from  time to  time  reasonably
          request.  Debtor will procure  and/or  execute,  have  executed,  have
          acknowledged,  and/or deliver to Secured  Party,  record and file such
          other  documents  and  notices as Secured  Party  deems  necessary  or
          desirable to protect its  interest in and rights under this  Agreement
          and  Collateral.  Debtor  will pay for all  filings,  searches,  title
          reports,  legal and other fees incurred by Secured Party in connection
          with any documents to be provided by Debtor pursuant to this Agreement

effect  through the last day of the lease term  specified  above (herein  "Lease
Term").  The Lease Term shall  commence  upon the earlier of (i)  completion  of
installation of the Equipment,  (ii) first  commercial use of the Equipment,  or
(iii)  sixty  (60) days from  shipment  of the of the bulk of the  equipment  if
completion of installation  has been delayed due to causes beyond the reasonable

Lessee  agrees to pay to Lessor the number of lease  payments  specified  above,
each in the amount  specified  above (herein  "Lease  Payments") for the payment
periods specified above (herein "Payment Periods"),  including any Advance Lease
Payments  specified  above,  with  the  first  Lease  Payment  being  due on the
Commencement Date, and the remaining Lease Payments being due on the same day of
each consecutive  Payment Period  thereafter for the duration of the Lease Term.
Lessee agrees to pay on demand, as a late charge,  1.5% per month limited by the
maximum rate permitted by law, on all overdue payments  hereunder,  whether such
payments  are due  prior to or after a Default  (as  hereinafter  defined).  All
payments  provided for herein shall be payable at the office of Lessor set forth
above, or at any other place designated by Lessor.  The Lease is a net lease and
Lessee  shall not be  entitled  to any  abatement  of,  reduction  of, or setoff
against  Lease  Payments  for  any  reason  whatsoever.  The  Lease  may  not be
terminated or canceled for any reason  whatsoever,  except as expressly provided
herein.  No amounts  hereunder  may be prepaid  without the  written  consent of
Lessor.

3.  DISCLAIMER OF WARRANTIES; LIMITATION OF REMEDY; LIMITATION OF
LIABILITY:  Lessee has selected both the Equipment and the supplier from whom at
Lessee's  request Lessor agrees to purchase the Equipment.  LESSEE  ACKNOWLEDGES
THAT  LESSOR  HAS NO  SPECIAL  FAMILIARITY  OR  EXPERTISE  WITH  RESPECT  TO THE
EQUIPMENT.  LESSEE AGREES THAT THE EQUIPMENT  LEASED HEREUNDER IS LEASED "AS IS"
AND IS OF A SIZE,  DESIGN AND  CAPACITY  SELECTED  BY LESSEE AND THAT  LESSEE IS
SATISFIED  THAT THE SAME IS SUITABLE FOR LESSEE'S  PURPOSES,  AND THAT EXCEPT AS

EQUIPMENT.  If the  Equipment  is not  properly  installed,  does not operate as
represented or warranted by the vendor,  manufacturer  and/or service company or
is unsatisfactory for any reason, Lessee shall make any claim on account thereof
solely  against  the  vendor,  manufacturer  and/or  service  company and shall,
nevertheless, pay Lessor all amounts

                                       98

<PAGE>



payable under the Lease and shall not set up against  Lessee's  obligations  any
such claims as a defense, counterclaim,  deduction, setoff or otherwise. For the
Lease Term,  Lessor  hereby  appoints  Lessee as Lessor's  agent,  so long as no
Default (as  hereinafter  defined) has occurred and is continuing,  to assert at
Lessee's  expense (if any) and to the extent  permitted by  applicable  law, any
right Lessor may have against any vendor, manufacturer and/or service company to
enforce any product warranties with respect to the Equipment,  provided however,
Lessee shall indemnify and defend Lessor from and against all claims,  expenses,
damages,  losses and  liabilities  incurred or suffered by Lessor in  connection
with any such action taken.

4. TITLE;  IDENTIFICATION;  PERSONAL PROPERTY: Lessee acknowledges that, subject
to the  provisions  of Section 10 hereof,  title to the  Equipment  shall at all
times be vested in Lessor,  and no right,  title or  interest  in the  Equipment
shall pass to Lessee other than  conditioned  upon Lessee's  compliance with and
fulfillment of the terms and  conditions of the Lease,  the right to possess and
use the  Equipment for the full Lease Term.  Lessee agrees not to sell,  assign,
sublet,  pledge or otherwise encumber any interest in the Lease or the Equipment
and agrees to keep the same free from any lien, encumbrance,  right of distraint
or any other  claim  which may be  asserted  by any third  party.  Lessee  shall
immediately  notify Lessor in writing of any tax or other liens attaching to the
Equipment.  Lessor may require  plates or markings to be affixed to or placed on
the Equipment  indicating  Lessor's  interest.  Lessor and Lessee hereby confirm
their intent that the Equipment  always remain and be deemed  personal  property
even though said Equipment may hereafter  become  attached or affixed to realty.
Lessee  shall  obtain  all such  waivers  as Lessor  may  reasonably  require to
acknowledge Lessor's title to and assure Lessor's right to remove the Equipment,
including any landlord and mortgagee waivers.

Lessor when due, all taxes, fees and assessments,  including but not limited to,

together with any fines, penalties or interest thereon, now or hereafter imposed
by any  governmental  body, upon or with respect to, any of the Equipment or the
use,  possession,  ownership,  leasing,  operation,  delivery or return  thereof
(excluding  however,  franchise  taxes and any taxes  based on the net income of
Lessor).  Any fees, taxes or other amounts paid by Lessor upon failure of Lessee
to make such  payments set forth in this Section 5 shall be payable by Lessee to
Lessor  upon  demand by  Lessor.  Lessee  agrees to  indemnify  and hold  Lessor
harmless  from and  against any and all claims,  losses,  liabilities,  damages,
penalties,  actions and suits (including  reasonable legal costs and expenses in
connection  therewith)  incurred by Lessor which result from,  or relate to, the
manufacture,   purchase,   ownership,   maintenance,   modification,   delivery,
installation,  possession,  condition, use, acceptance,  rejection, operation or
return of the Equipment.

6.  INSTALLATION  AND  DELIVERY:  Lessee shall  provide a suitable  installation
environment for the Equipment as specified in the applicable  manufacturer's  or
vendor's  manuals,  and except as  otherwise  specified by the  manufacturer  or
vendor,  furnish all labor  required  for  unpacking  and  placing  each item of
Equipment  in the desired  location.  Lessee shall also be  responsible  for any
delivery,   rigging,   destination  and  installation  charges  charged  by  the
manufacturer or vendor with respect to the Equipment.

Equipment in accordance with all applicable  manufacturer  and vendor manuals or
instructions by fully qualified

regulations. The equipment shall be used for business purposes only and only for
its  normally  intended  purpose.  For said Lease Term,  Lessee  shall  properly
maintain  the  Equipment  or  cause  it to be  properly  maintained,  by a fully
qualified service company, and shall immediately notify Lessor in writing of the
entity  maintaining  the  Equipment  and of any  change  of  such  entity.  Such
maintenance shall be performed in accordance with all requirements  necessary to
enforce all product  warranty rights.  All operating and maintenance  costs with

operate  or locate the  Equipment  in any area  excluded  from  coverage  by any
insurance  required under the Lease;  (b) abandon the  Equipment;  (c) alter the
Equipment;  (d) permit the Equipment to be removed from the  equipment  location
specified  above (herein  "Equipment  Location"),  or any  subsequent  location,
without  the  prior  written  consent  of  Lessor,  which  consent  shall not be
unreasonably  withheld;  (e) without the prior written consent of Lessor,  allow
the  Equipment  or any item of it, to be affixed to realty in such  manner as to
cause the  Equipment or such item to become a fixture;  or (f) without the prior
written consent of Lessor,  affix or install any accessory,  equipment or device
on any item of  Equipment  if such (i) is not  readily  removable,  or (ii) will
impair the originally intended function or use of such Equipment. All additions,
repairs,  parts,  accessories,  equipment and devices attached or affixed to any
item of Equipment which are not readily removable,  shall become the property of
Lessor and part of the Equipment for all purposes hereof.  Lessor shall have the
right from time to time during normal business hours to enter upon the Equipment
Location or elsewhere for the purpose of confirming the existence,  condition or
proper maintenance of the Equipment.

8. RISK OF LOSS;  INSURANCE:  (a) Lessee  agrees  that it shall bear all risk of
loss, damage to or destruction of the Equipment. Lessee shall give Lessor prompt
notice of any damage to or loss of the  Equipment or of any  occurrence  arising
from the  possession,  use or operation of the  equipment  resulting in death or
bodily  injury or damage to  property.  In the event of damage to any item(s) of
Equipment,  Lessee shall  immediately place such item(s) in good repair (with no
abatement  of Lease  Payments),  with the  proceeds  of any  insurance  recovery
applied to the cost of such repair. Should any item(s) of Equipment become lost,
stolen,  destroyed,  worn out,  damaged beyond repair,  condemned,  confiscated,
seized or requisitioned (herein "Event of Loss"), Lessee shall, at the option of
Lessor,  either (i) replace the same with like equipment in good repair (with no
abatement of Lease  Payments),  or (ii) pay to Lessor on the lease  payment date
immediately  following such Event of Loss (herein "Loss Payment Date"),  the pro
rata  portion  relating  to such  item(s) of the  greater of (A) the Fair Market
Value (as  hereinafter  defined)  of the  Equipment  calculated  as of the lease
payment date immediately prior to such Event of Loss, or (B) the stipulated loss
value of the Equipment as set forth in the schedule  hereto (herein  "Stipulated
Loss Value")  calculated for the Payment Period  immediately  preceding the Loss
Payment Date,  plus any and all Lease Payments and other payments due but unpaid
as of the day  immediately  preceding  the Loss  Payment  Date  relating to such
item(s)  whereupon the Lease shall terminate as to such item(s) and Lessor shall
adjust  the  remaining   Lease  Payments  and  stipulated  loss  value  schedule
accordingly.

         (b)  For  the  Lease  Term,  Lessee,  at its  expense,  shall  maintain
comprehensive general liability insurance, and "fire and allied perils" and "all
risks" property insurance with respect to the Equipment, both in such amounts as
Lessor shall require,  except that such property insurance shall be in an amount
at least equal to the greater of the full replacement  value of the Equipment or
the applicable Stipulated Loss Value thereof; and such insurance shall be placed
with carriers  acceptable to Lessor.  The liability  insurance policy shall name
Lessor as additional insured and the property

                                       100

insurance  policy shall name Lessor as loss payee to the extent its interest may
appear, and both policies shall provide that they may not be canceled or altered

furnish to Lessor  within  thirty  (30) days of  delivery  of the  Equipment,  a
certificate of insurance that such coverage is in effect,  however, Lessor shall
be under no duty  either  to  ascertain  the  existence  of or to  examine  such
insurance policies or to advise Lessee in the event that such insurance coverage
does not comply with the requirements hereof.

9. DEFAULT AND REMEDIES:  (a) Any of the following shall constitute a default by

hereunder  when due and such  remains  unremedied  for a period of ten (10) days
from the due date;  or (ii) failure by Lessee to comply with any  provisions  or

Equipment to levy or execution or other judicial  process which is not or cannot
be  removed  within  thirty  (30)  days  from  the  execution  thereof;  or  (v)
commencement of any insolvency,  bankruptcy or similar proceedings by or against
Lessee  or any  guarantor  of  any of  Lessee's  obligations  hereunder  (herein
"Guarantor"),  including any  assignment by Lessee for the benefit of creditors,
and in the  case of any  such  involuntary  proceedings,  such is not  dismissed
within thirty (30) days of institution; or (vi) any act of Lessee which imperils
the value of the  Equipment  or the  prospect  of full  performance  of Lessee's
obligations  hereunder,   including  but  not  limited  to  the  liquidation  or
dissolution  of Lessee or the  commencement  of any acts  relative  thereto,  or
without the prior written  consent of Lessor,  any sale or other  disposition of
all or substantially all of the assets of Lessee, or any merger or consolidation
of Lessee unless Lessee is the surviving entity, or the cessation of business by
Lessee;  or (vii) a default by Lessee under any other  agreement  with Lessor or
any assignee of the Lease;  or (viii) the death or  dissolution  of Lessee or of
any  Guarantor,  the  withdrawal  of  any  partner  of  Lessee  if  Lessee  is a
partnership, or the inability of Lessee or of any Guarantor hereunder to perform
any of the obligations contained herein or in any applicable guaranty.

         (b)  Upon  any  Default,  Lessor  may  exercise  any one or more of the
following  remedies  (which  remedies  shall be  cumulative):  (i) terminate the
Lease;  (ii) declare all remaining  Lease  Payments for the balance of the Lease
Term  discounted at a per annum rate of six percent (6%), plus all other amounts
due from Lessee hereunder,  immediately due and payable in full; (iii) by notice
to Lessee declare the Stipulated Loss Value of the Equipment  calculated for the
Payment Period  immediately  following such notice (herein  "Calculation  Date")
immediately due and payable, together with (A) all due but unpaid Lease Payments
through the day prior to the  Calculation  Date,  and (B) all other  amounts due
hereunder  (including  late charges);  (iv) secure  peaceable  repossession  and
removal of the Equipment by Lessor or its agent without  judicial  process;  (v)
demand that Lessee return the Equipment to Lessor in accordance  with Section 11
hereof;  (vi) sell,  lease or  otherwise  dispose of the  Equipment at public or
private sale without  advertisement  or notice except that required by law, upon

purchaser  at any such  sale;  (vii)  demand  that  Lessee pay all  expenses  in
connection with the Equipment relating to its retaking, refurbishing, selling or
the like; (viii) exercise any other right or remedy which may be available to it
under applicable law or proceed by appropriate court action to enforce the Lease
or recover damages for the breach hereof.  To the extent permitted by applicable
law,  Lessee  waives all  rights it may have to limit or modify any of  Lessor's
rights and remedies hereunder, including but

                                       101

<PAGE>



not  limited  to,  any right of  Lessee to  require  Lessor  to  dispose  of the
Equipment or otherwise mitigate its damages hereunder.

10.  PURCHASE  OPTION:  Provided no Default has occurred and is  continuing  and
provided the Lease shall not have previously  terminated,  Lessee shall have the
option,  exercisable  by written  notice to Lessor  received  by Lessor at least
ninety (90) but not more than one hundred eight (180) days before the expiration
of the Lease Term,  to purchase on the day  following  the last day of such term
(herein "Purchase Date"),  all but not less than all of the Equipment subject to
the Lease for its Fair  Market  Value.  Fair  Market  Value shall mean the value
which would be obtained in an arm's- length transaction  between an informed and
willing  buyer-user  (other  than a Lessee  currently  in  possession  or a used
equipment dealer) under no compulsion to buy, and an informed and willing seller
under compulsion to sell and, in such  determination,  costs of removal from the
location of current use shall not be a  deduction  from such value.  Fair Market
Value  shall be  determined  by the  mutual  agreement  of Lessor  and Lessee in
accordance with the preceding sentence.  If Lessee and Lessor cannot agree, Fair
Market Value shall be determined by a qualified  independent equipment appraiser
selected  by Lessor and  approved  by Lessee,  and Lessee  shall pay the cost of
apprisal.  Provided Lessee has exercised such option, Lessee shall pay to Lessor
on the Purchase Date the  aforementioned  purchase price in cash,  together with
all sales and other taxes  applicable  to the transfer of the  Equipment and any
other  amounts as may then be due and owing  hereunder,  whereupon  Lessor shall
transfer its interest in the Equipment to Lessee  without  recourse or warranty,
on an as-is,  where-is  basis.  In the event that Lessee fails to exercise  such
purchase  option,  Lessee  shall  (upon  termination  of the  Lease)  return the
Equipment to Lessor on demand,  in accordance  with the provisions of Section 11
hereof.

11.  RETURN OF  EQUIPMENT:  Upon  demand of Lessor  pursuant  to Section 9 or 10
hereof,  Lessee,  at its own risk and  expense,  shall  immediately  return  the
Equipment  to Lessor,  packed for  shipment in  accordance  with  Manufacturer's
specifications,   in  good  working   order  and  eligible  for   manufacturer's
maintenance.  If available freight prepaid and insured,  to such location within
the continental United States as Lessor shall designate.

12. LESSEE  REPRESENTATIONS AND ASSURANCES:  Lessee represents:  that it is duly
organized and validly  existing under the laws of its state of organization  and
by  consummation  of  this  transaction,  Lessee  is  not  in  violation  of any
governmental  statute or regulation,  nor will  consummation of this transaction
cause any breach,  default or violation of the certificate of  incorporation  or
by-laws (if Lessee is a corporation), the partnership certificate or partnership
agreement (if Lessee is a partnership) or any judgment, decree or agreement, all
as may apply to Lessee; that this transaction was duly authorized by appropriate
corporate or partnership action (as applicable); and the Lease is enforceable in
accordance with its terms.  Lessee shall promptly  execute and deliver to Lessor
such further  documents  and take such further  action as Lessor may  reasonably
request in order to more  effectively  carry out the  intent and  purpose of the
Lease.  Lessee shall provide Lessor with audited and other financial  statements
and such other information as Lessor shall reasonably request from time to time.

13.  NOTICES;  CHANGES;  FILINGS:  Notices,  requests  or  other  communications
required  hereunder  to be sent to either party shall be in writing and shall be
(a) by United  States first class mail,  postage  prepaid,  and addressed to the
other party at the  address  specified  above (or to such other  address as such
party shall have designated by proper notice) or (b) by personal delivery.

                                       102

Lessee consents to service of process by certified mail at its address above (or
to such other  address as Lessee  shall have  designated  ;by proper  notice) in
connection with any legal action brought by Lessor.  Lessee authorizes Lessor to
fill in descriptive  material herein  (including  serial numbers) and to correct
any patent errors hereunder.  Lessee shall execute and authorizes Lessor to file
with such  authorities  and at such  locations  as Lessor may deem  appropriate.
Uniform  Commercial Code financing  statements  relating to the Equipment and/or
the Lease,  and Lessee  agrees to  reimburse  Lessor  upon  demand for all costs
incurred  relative  thereto.  In addition,  Lessee  agrees that an original or a
photocopy  of the Lease  (including  any  addenda,  attachments  and  amendments
hereto) may be filed by Lessor as a Uniform Commercial Code financing statement.
Lessee agrees to immediately notify Lessor in writing, of any change in Lessee's
name or address, or discontinuance of its place or places of business.

14.  ASSIGNMENT  BY LESSOR:  The Lease or any  interest of Lessor  herein may be
assigned by Lessor. UPON NOTICE OF SUCH ASSIGNMENT LESSEE AGREES TO PAY DIRECTLY
TO ASSIGNEE WITHOUT ABATEMENT,  DEDUCTION OR SETOFF ALL AMOUNTS WHICH BECOME DUE
HEREUNDER  AND  FURTHER  AGREES  THAT IT WILL NOT ASSERT  AGAINST  ASSIGNEE  ANY
DEFENSE,  COUNTERCLAIM  OR SETOFF  FOR ANY REASON  WHATSOEVER  IN ANY ACTION FOR
PAYMENT  OR  POSSESSION  BROUGHT BY  ASSIGNEE.  Upon any such  assignment,  such
assignee  (herein  "Assignee")  shall have and be entitled to any and all rights
and remedies of Lessor  hereunder,  all  references in the Lease to Lessor shall
include  Assignee  except  that  Assignee  shall  not  be  chargeable  with  any
obligations or liabilities  of Lessor  hereunder.  Lessee shall (if requested by
Lessor) acknowledge in writing any assignments  (including any material terms of
the Lease) in a form supplied by Lessor.

15.  MISCELLANEOUS:  THE LEASE OR ANY PART HEREOF, MAY NOT BE ASSIGNED BY LESSEE
WITHOUT THE WRITTEN CONSENT OF LESSOR and shall be binding upon and inure to the
benefit of the parties hereto, their legal representatives, permitted successors
and assigns.  No amendment hereunder shall be effective unless in writing signed
by the  parties  hereto and no waiver  hereunder  shall be  effective  unless in
writing,  signed by the party to be charged. No failure to exercise, no delay in
exercising,  and no  single  or  partial  exercise  on the part of Lessor of any
right, remedy, or power hereunder, shall operate as a waiver thereof or preclude
Lessor from exercising any other right, remedy or power hereunder. Any provision
of the  Lease  which is  unenforceable  in any  jurisdiction  shall,  as to such
jurisdiction,   be   ineffective   to  the   extent  of  such   prohibition   or
unenforceability,  without  invalidating  the remaining  provisions  hereof.  No
action,  regardless  of form,  arising out of the Lease may be brought by Lessee
more  than  two  (2)  years   after  the  cause  of  action  has   arisen.   The
representations,  warranties,  obligations  and  indemnities of Lessee under the
Lease shall  survive the  termination  of the Lease to the extent  required  for
their full observance and performance. The obligations of each co-maker (if any)
of the Lease, shall be primary, joint and several, and each such co-maker hereby
irrevocably  consents to any extension of time for payments and/or the execution
of any  refinancing  agreement  relative to the Lease.  In the event that Lessee
fails to meet any of its obligations hereunder, Lessor may at its option satisfy
such obligation and Lessee shall  reimburse  Lessor on demand  therefor.  In the
event that legal or other  action is required to enforce  Lessor's  rights under
the Lease  (including the exercise of remedies  under Section 9 hereof).  Lessee
agrees to reimburse Lessor on demand for its reasonable  attorneys' fees and its
other related costs and expenses.  The captions in the Lease are for convenience
only and shall not define or limit any of the terms  hereof.  THE LEASE SHALL BE
GOVERNED  AND  CONSTRUED  IN  ACCORDANCE  WITH THE LAWS OF THE STATE OF  FLORIDA
WITHOUT GIVING

                                       103

                                                     made   no   agreements   or
                                                     representations  except  as
                                                     set forth  herein  and that
                                                     (s)he is duly authorized
ACCEPTED BY:                                         to execute the Lease on

"Building"), located at 9603 White Rock Trail, Dallas, Dallas County, Texas. The
area  hereby  leased in the  Building  (and  hereinafter  referred to as "Leased
Premises")  is shown  outlined  on the floor  plan  drawing  attached  hereto as
Exhibit "A."

TERM:  This  Lease is for a term  (the  "Term")  of  Eighty  four  (84)  months,
commencing on March 1, 1996 (the "Commencement  Date"), and expiring on February
28, 2003 (the "Expiration  Date"),  unless sooner  terminated in accordance with
other provisions of this Lease.

RENT:

As rental  for the Lease and use of the  Leased  Premises,  Lessee  shall pay to
Lessor the Base Rent and the Additional  Rent called for in this Paragraph 3. As
used herein,  the term "Rent"  includes both Base Rent and Additional  Rent. All
Rent shall be paid  without  demand and without  deduction,  abatement or setoff
except as otherwise provided in this Lease. All Rent, and other payments due and
becoming  due by Lessee to Lessor  under  this Lease  shall be made at  Lessor's
address  given  below or at such other  places as Lessor  may from  time-to-time
designate by written notice given to Lessee.

Lessee  agrees to pay to Lessor,  monthly in  advance,  on the first day of each
calendar  month during the Term  hereof,  monthly  base rental  payments  ("Base
Rent") in the amount of eleven  thousand  four hundred  forty seven  dollars and
twelve cents  ($11,610.29).  If Lessee  occupies  the Leased  Premises on a date
other tan the first day of a calendar  month,  the Base Rent of that month shall
be prorated.  The rent for the months of March 1996,  April 1996,  and June 1996
will be abated.

In addition to Base Rent,  Lessee shall pay to Lessor  monthly  during the dates
specified,  along with the Base Rent, an Additional Rent ("Additional  Rent") in
the amount of:

From March 1, 1997 to February 28, 1998,  Three  hundred forty eight dollars and
thirty  one cents  ($348.31)  From March 1, 1998 to  February  28,  1998,  Seven
hundred seven dollars and seven cents  ($707.07)  From March 1, 1999 to February
29, 2000, One thousand  seventy six dollars and fifty nine cents ($1076.59) From
March 1, 2000 to February  28,  2001,  One  thousand  four  hundred  fifty seven
dollars and twenty cents ($1457.20) From March 1, 2001 to February 28, 2002, One
thousand eight hundred forty nine dollars and

                                       112
<PAGE>



twenty two cents ($1849.22)
From March 1, 2002 to February  28, 2003,  Two thousand two hundred  fifty three
dollars and no cents ($2253.00)

Lessee shall retain deposit with Lessor (the "Security  Deposit")  $48,421.07 as
security for the full and faithful  performance of every provision of this Lease
to be performed by Lessee.  If Lessee  defaults with respect to any provision of
this  Lease,  including  (without  limitation)  the  provisions  relating to the
payment of Rent, Lessor may use, apply or retain all or any part of the Security
Deposit  for the  payment  of any Rent or any  other sum in  default  or for the
payment of any other amount which Lessor may spend or become  obligated to spend
by reason of Lessee's default,  or to compensate Lessor for any other loss, cost
or damage which Lessor may suffer by reason of Lessee's Default.  If any portion
of the Security  Deposit is so used or applied,  Lessee  shall,  within ten days
after written demand therefor,  deposit cash with Lessor in an amount sufficient
to restore the  Security  Deposit to its  original  amount.  Lessor shall not be
liable for payments of interest with respect to the Security Deposit.  If Lessee
shall fully and faithfully perform every provision of this Lease to be performed
by Lessee,  the Security  Deposit,  or any balance thereof  remaining,  shall be
returned to Lessee,  or, at Lessor's option,  to the last transferee of Lessee's
interest hereunder,  at the expiration of the Term and upon Lessee's vacation of
the Leased  Premises.  In the event the Building is sold,  the Security  Deposit
shall be transferred to the new owner.

If any increase in the fire and extended  coverage  insurance  premiums  paid by
Lessor for the Building in which Lessee occupies space is caused by Lessee's use
and occupancy of the Leased  Premises,  or if Lessee vacates the Leased Premises
and causes an increase in such  premiums,  then Lessee  shall pay as  Additional
Rent the amount of such increase to Lessor.

OPERATION EXPENSE REIMBURSEMENT:  Intentionally omitted.

OPERATING EXPENSES:  Intentionally omitted.

SIGNS:

Lessor shall furnish and install  Lessee's name and suite number on the building
directory.  Lessor  shall  also  furnish  and  install at the  entrance  door to
Lessee's  premises a uniform  suite number plate and a name plate.  Signs,  name
plates or graphics  which are wholly within the Leased  Premises and not visible
from the exterior of the Building or from public spaces within the Building will
be permitted without the consent of the Lessor. Lessor shall furnish and install
Lessee's name (PhyMed  Diagnostic  Imaging) on an outside sign  approximately 20
feet by 2 feet on the northwest side of the Building.

Lessee agrees that no other signs of any description shall be erected or painted
in or about the Leased Premises.  Lessee shall, at Lessor's  option,  remove all
signs at the termination of this Lease, and the installation of removal shall be
in such manner as to avoid any injury, defacement or overloading of the Building
or other improvements.

USAGE:

Lessee  warrants and represents to Lessor that the Leased Premises shall be used
and occupied  only for the purposes of general  office use,  medical  diagnostic
imaging and physician office use.

                                       113

<PAGE>



Lessee  shall occupy the Leased  Premises,  conduct its business and control its
agents,  employees,  invitees  and  visitors  in  such a  manner  as is  lawful,
reputable  and will not create any  nuisance or  otherwise  interfere  with any,
annoy or disturb any other tenant in its normal business operations or Lessor in
its management of the Building.

Lessee  shall not  commit,  or suffer to be  committed,  any waste on the Leased
Premises,  nor shall  Lessee  permit the Leased  Premises  to be used in any way
which would, in the opinion of Lessor, cause Lessor's fire and extended coverage
insurance to be canceled or the rate  therefor to be increased  (or, at Lessor's
option shall pay any such increase).

The sidewalks,  halls, exits, entrances,  elevators,  stairways and Common Areas
shall not be obstructed by Lessee or used for any purpose other than for ingress
to or egress from the Leased Premises. The hallways, exits, entrances, elevators
and stairways of the Building are for the use of the general public,  but Lessor
shall in all cases retain the right to control and prevent access thereto by any
persons whose presence,  in the judgment of Lessor,  shall be prejudicial to the
safety, character, reputation and interest of the Building and its tenants.

Certain areas  ("Common  Areas") of the Building as it exists from  time-to-time
may be  designated  by Lessor as Common Areas for the common use of all tenants,
including  (among  other  facilities),  corridors,  elevators,  halls,  lobbies,
deliver stairways, drinking fountains, public toilets and the like, all of which
will be subject to Lessor's sole management and control.

Lessee shall not use, nor shall Lessee permit its licensees, employees, invitees
or agents,  to use any  portion of the Leased  Premises  in any way that  causes
interference  with or  deterioration  of Metroplex  Telephone  Company's  signal
quality  in its  transmission  of  cellular  telephone  and radio  communication
signals or prohibit  Metroplex  Telephone  Company in any way from  operating in
compliance with rules and regulations  established by the Federal Communications
Commission or any other regulatory  body. In the event of any such  interference
and that  interference  does not cease promptly,  the parties  acknowledge  that
continuing interference may cause irreparable injury and, therefore, the injured
party shall have the right,  in addition to any other rights that it may have at
law or in equity, to bring action to enjoin such interference. In the event such
interference   is  in  violation  of  the  Federal   Communications   Commission
regulations, Metroplex Telephone Company shall also have the right to pursue any
remedies that may be available to it against such interfering party.

CERTIFICATE OF OCCUPANCY:  Lessee may, prior to the  commencement of the term of
this Lease,  apply for a Certificate of Occupancy from the municipality in which
the Demised Premises are located. If Lessee is unable to obtain a Certificate of
Occupancy  prior to the  Commencement  Date,  Lessee  shall  have  the  right to
terminate  this  Lease by  written  notice  to  Lessor  if  Lessor  or Lessee is
unwilling  or unable to cure the defects  which  prevented  the  issuance of the
Certificate  of Occupancy.  Lessor may, but has no obligation  to, cure any such
defects  preventing  the issuance of a Certificate  of Occupancy,  including any
repairs,  installations,  or  replacements  of any items which are not presently
existing on the Demised  Premises,  or which have not been expressly agreed upon
by Lessor in writing.

INSURANCE  AND  INDEMNITY:  Lessee's  Insurance.  Lessee,  at its sole  cost and
expense,  shall obtain and  maintain in effect as long as this Lease  remains in
effect and during such other time as Lessee  occupies  the  Premises or any part
thereof, insurance policies providing at least the following coverages:

                                       114

<PAGE>




General Liability Insurance, in occurrence form, insuring Lessee against any and
all liability  for injury to or death of a person or persons,  and for damage to
or  destruction  of property,  occasioned  by or arising out of or in connection
with the use or occupancy  of the  Premises or the  business  operated by Lessee
thereon,  and including  contractual  liability  coverage for Lessee's indemnity
obligations  under this  Lease  (other  than those  contained  in  Paragraph  18
hereof),  to afford protection with a minimum combined single limit of liability
of at least One Million Dollars ($1,000,000.00); and

Workers  Compensation  and similar  insurance  offering  statutory  coverage and
containing  statutory  limits and  employer's  liability  insurance  in form and
amount  deemed  reasonable  by Lessee in the  exercise of its  prudent  business
judgment.

Such policies will be  maintained in companies  having a "General  Policyholders
Rating"  of at least B plus as set forth in the most  current  issue of  "Best's
Insurance  Guide,"  and will be  written  as  primary  policy  coverage  and not
contributing  with,  or in excess of, any  coverage  which  Lessor  shall carry.
Lessee shall deposit  certificates of such required  insurance with Lessor prior
to the earlier to occur of (x) the Commencement Date of this Lease, or (y) shall
not be canceled or  materially  altered  except after thirty (30) days'  written
notice to Lessor.  Lessee shall have the right to provide the coverages required
herein under blanket policies  provided that the coverage  afforded shall not be
diminished by reason thereof.

         Lessee's Property. All furnishings,  fixtures,  equipment, and property
of every kind and  description  of Lessee  and  persons  claiming  by or through
Lessee  which may be on the  Premises  shall be at the sole  risk and  hazard of
Lessee and no part of loss or damage thereto for whatever cause is to be charged
to or borne by Lessor.

         Lessee's  Insurance.  Lessor shall at all times during the term of this
Lease  maintain a policy or  policies of  insurance  with the  premiums  paid in
advance, issued by and binding upon some solvent insurance company, such company
having a "General  Policyholder's Rating" of at least B plus as set forth in the
most recent issue of "Best's  Insurance  Guide,"  insuring the Building  against
lost or damage by fire,  explosion  or other  hazards and  contingencies  to the
extent of at least 80% of replacement cost;  provided,  that Lessor shall not be
obligated in any way or manner to insure any personal property  (including,  but
not limited to, any furniture,  machinery, goods or supplies) of Lessee or which
Lessee may have upon or within the Leased Premises or any fixtures  installed by
or paid for by Lessee  upon or within the Leased  Premises  or any  improvements
made by or for Lessee.

JANITORIAL SERVICE:  Lessor shall furnish janitorial services during the term of
this Lease. The janitorial  service shall be provided five times per week during
the term of this Lease.  Lessee shall pay for cost of cleaning services required
by non-standard improvements or special operations.

conditioning,  electrical  costs) for the Premises  described  in paragraph  (1)

shall furnish  Lessee hot and cold water at those points of supply  provided for

in the Building, and a temperatures and in

                                       115

<PAGE>



amounts  as are  considered  by Lessor  to be  standard),  routine  maintenance,
painting  and  electrical  lighting  service  for all public  areas and  special
service  areas of the Building in the manner and to the extent  deemed by Lessor
to be  standard.  Failure  by Lessor  to any  extent to  furnish  these  defined
services, or any cessation thereof,  resulting from causes beyond the control of
Lessor shall  neither  render Lessor liable in any respect for damages to either
person or property,  be construed as an eviction of Lessee,  create an abatement
of rent nor  relieve  Lessee  from  fulfillment  of any  covenant of this Lease.
Should any of the  equipment or machinery  break down, or for any cause cease to
function  properly,  Lessor  shall use  reasonable  diligence to repair the same
promptly,  but  Lessee  shall  have  no  claim  for  rebate  on  account  of any
interruption I service occasioned from the repairs.

REPAIRS AND MAINTENANCE:

Unless otherwise  expressly  provided,  Lessor shall not be required to make any
improvements,  replacements  or repairs of any kind or  character  to the Leased
Premises  during  the  term of this  Lease,  except  repairs  to  walls,  doors,
corridors,  windows and other  structures  and equipment  within and serving the
Leased  Premises,  and  additional  maintenance  as may be necessary  because of
damage by persons other than Lessee, its agents, employees,  invitees, licensees
or  visitors,  and as may be necessary  because of damage by persons  other than
Lessee, its agents,  employees,  invitees,  licensees or visitors, and as may be
necessary  solely  because of the  negligence of Lessor,  which repairs shall be
made by Lessor at its expense beginning not more than fifteen days after written
notice by  Lessee.  Lessor  shall not be liable to Lessee,  except as  expressly
provided in this Lease, for any damage or inconvenience, and Lessee shall not be
entitled  to any  abatement  or  reduction  of Rent,  b reason  of any  repairs,
alterations  or additions  made by Lessor  under this Lease.  Subject to 30 days
prior  written  notice  notifying  Lessor  of  specific  repairs  that  are  the
responsibility of Lessor as defined in this Paragraph 12(a), and allowing Lessor
reasonable time to make said repairs, Lessee shall be entitled to a prorated per
day and prorated  per square foot  abatement or reduction of rent for any of the
days following the notice period for that specific  effected area of this Lease,
b reason of any unreasonable failure by Lessor to make said repairs.

All requests for repairs or maintenance  that are the  responsibility  of Lessor
pursuant to any provision of this Lease must be made in writing to Lessor at the
address set forth below.

CARE OF LEASED PREMISES:

Lessee  shall,  at its own cost and  expense,  repair or replace  any damages or
injury to all or any part of the Leased  Premises  caused by Lessee or  Lessee's
agents, employees, invitees, licensees or visitors; provided, however, if Lessee
fails to make the repairs or replacements  promptly,  Lessor may, at its option,
make the repairs or  replacements  and Lessee shall reimburse the cost to Lessor
on demand.

Lessee  shall not allow any damage to be  committed on any portion of the Leased
Premises,  and upon expiration or termination of this Lease, by lapse of time or
otherwise,  Lessee  shall  deliver  the  Leased  Premises  to  Lessor in as good
condition as at the date of first  possession of Lessee,  ordinary wear and tear
excepted. The cost and expense of any repairs necessary to restore the condition
of the Leased  Premises  shall be borne by Lessee,  and if Lessor  undertakes to
restore  the  Leased  Premises,  Lessee  shall  reimburse  Lessor  for the costs
thereof.

All the rights and  remedies of Lessee  created in this Lease are in addition to
those otherwise created whether by law or agreement.  All rights and remedies of
Lessor are cumulative and may be exercised singly or  concurrently.  A waiver by
Lessor of any Event of Default or any right or remedy on any  occasion  will not
be a bar to the exercise of any remedy on any subsequent  occasion.  Exercise by
Lessor of any right or remedy  granted by this Lease or  otherwise  available to
Lessor  shall not be deemed  to be an  acceptance  of  surrender  of the  Leased
Premises  by Lessee,  whether by  agreement  or by  operation  of law,  any such

<PAGE>



Lessee's obligations under this Lease, and Lessor may enforce any such liability
notwithstanding any termination.

RECOVERY FROM LESSEE:

Lessee will be liable to Lessor for any  deficiency  remaining  should rents and
other payments  actually received by Lessor from any new tenant upon a reletting
pursuant  to  subparagraph  (a)(iv) of  Paragraph  28 be less than the Rents and
other payments for which lessee is obligated under the terms of this Lease.

All the rights and  remedies of Lessee  created in this Lease are in addition to
those otherwise created whether by law or agreement.  All rights and remedies of
Lessor are cumulative and may be exercised singly or  concurrently.  A waiver by
Lessor of any Event of Default or any right or remedy on any  occasion  will not
be a bar to the exercise of any remedy on any subsequent  occasion.  Exercise by
Lessor of any right or remedy  granted by this Lease or  otherwise  available to
Lessor  shall not be deemed  to be an  acceptance  of  surrender  of the  Leased
Premises  by Lessee,  whether by  agreement  or by  operation  of law,  any such
surrender to be affected only by the written agreement of Lessor and Lessee.

If it is necessary  for Lessor to bring suit in order to collect any  deficiency
from  Lessee,  Lessor may allow such  deficiencies  to  accumulate  and bring an
action on several or all of the accrued  deficiencies  at any one time. Any such
suit will be without  prejudice to the right of Lessor to bring a similar action
for any subsequent  deficiency or  deficiencies.  Any amount collected by Lessor
from subsequent tenants for any calendar month in excess of the monthly Rent and
other charges provided in this Lease shall be credited to Lessee in reduction of
Lessee's  liability  for any  calendar  month for which the amount  collected by
Lessor may be less than the  monthly  Rent and other  charges  provided  in this
Lease.

If  Lessee  fails  to keep or  perform  punctually  any of  Lessee's  covenants,
agreements or undertakings  contained in this Lease, Lessor may take such action
as,  in  the   judgment  of  Lessor,   necessary   to  cure  such   failure  ore
nonperformance,  and Lessee shall,  upon demand,  reimburse Lessor for all costs
and  expenses  incurred by Lessor in so doing.  No action  taken by Lessor under
this  subparagraph  (d) will be a waiver of any Event of Default  which may have
occurred  or exist or any  right  or  remedies  to  which  Lessor  is  otherwise
entitled.

ACTS OF GOD:  Lessor shall not be required to perform any covenant or obligation
in this  Lease,  or be  liable in  damages  to  Lessee,  if the  performance  or
nonperformance of the covenant or obligation is delayed,  caused by or prevented
by an act of God or force majeure.

ATTORNEY'S FEES: In the event Lessee defaults in the performance of any of their
terms,  covenants,  agreements or conditions  contained in this Lease and Lessor
places in the hands of an attorney  for  enforcement  of all or any part of this
Lease,  the  collection  of any Rent due or to  become  due or  recovery  of the
possession  of the  Leased  Premises,  Lessee  agrees to pay  Lessor  reasonable
attorney's fees for the services of the attorney, whether suit is actually filed
or not. In no event shall the attorney's fees be less than fifteen percent (15%)
of the outstanding balance owed by Lessee to Lessor.

an amount equal to one hundred fifty percent (150%) of the Rent which would have
been payable by Lessee had the holdover  period been a part of the original Term
of this Lease.  If holding over,  Lessee agrees to vacate and deliver the Leased
Premises to Lessor upon  Lessee's  receipt of notice from Lessor to vacate.  The

(sometimes called the "Purchaser") under the terms,  covenants and conditions of
this  Lease  for the  balance  of the  term  remaining,  and any  extensions  or
renewals,  with the same force and effect as if the Purchaser  were Lessor under
this  Lease,  and  Lessee  agrees  to  attorn to the  Purchaser,  including  the
mortgagee  under any such  mortgage  if it be the  Purchaser,  as its Lessor the
attornment  to be  effective  and  self-operating  without the  execution of any
further  instruments  upon the  Purchaser  succeeding  to the interest of Lessor
under  this  Lease.  The  respective  rights and  obligations  of Lessee and the
Purchaser upon the  attornment,  to the extent of the then remaining  balance of
the term of this Lease,  and any extensions  and renewals,  shall be and are the
same as set forth in this Lease.

interest in the Leased Premises cease to exist for any reason during the term of
the  Lease,  then  notwithstanding  the  happening  of  such  event  this  lease
