Item 1.  Description of Business

Business Development

         The  Registrant  was  organized  under  the laws of  British  Columbia,
Canada,   on  March  12,   1980,   under  the  name  of  Sooner   Energy   Corp.
("Sooner-British  Columbia").  On  June 1,  1994,  at an  extraordinary  general
meeting of members of Sooner-British  Columbia,  a special resolution was passed
for the  continuance  of the  company  as a Wyoming  corporation  in the  United
States. On such date,  Sooner-British Columbia was then"continued" as a Wyoming
corporation  with the same name  ("Sooner-Wyoming")  and was immediately  merged
into a wholly-owned  subsidiary of Sooner-Wyoming which had been incorporated in
Oklahoma under the name of Tatonka  Energy,  Inc.  ("Tatonka").  Tatonka was the
surviving  corporation  in the  merger  and is  referred  to in this  report  as
'Tatonka" or the 'Company.'

         On April 3, 1998, the Company  acquired 80% of the  outstanding  common
shares of Phy.Med., Inc., a Texas corporation ('PhyMed") in a reverse triangular
merger.

         In connection  with the Merger the Company issued and George C. Barker,
individually, and as Trustee of the Phy.Med., Inc. Employee Stock Ownership Plan
(the "ESOP"),  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 outstanding, would constitute 87.9%
of the Company's then outstanding 78,430,965 shares of Common Stock.

         The parties involved in the merger 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, Mr. Barker and the
ESOP  will own  6,941,540  shares  of the  7,843,097  shares,  $.01  par  value,
outstanding  (7,933,190  shares on a fully  diluted  basis).  The  Company  will
continue to have 50,000,000 shares of Common Stock authorized.

         The  Company's  registered  office for service in Oklahoma is 1601 N.W.
Expressway,  Suite 1910, Oklahoma City, Oklahoma 73118. The executive offices of
the Company are  located in Dallas,  Texas at 9603 White Rock Trail,  Suite 100,
Dallas,  Texas 75238. The main business  telephone number of the Company at such
address is (214) 340-9912.

Business of the Company

         The Registrant  formerly  engaged in the exploration and development of
oil and gas products.  Arum Petroleum  Corp.,  a wholly-owned  subsidiary of the
Registrant,  was  dissolved in 1993 with its  remaining  assets and  liabilities
distributed  to its parent  corporation.  Effective  May 1,  1994,  the stock of

                                       3

<PAGE>


Sooner Acquisition Corp.,  another  wholly-owned  subsidiary,  was sold with the
Registrant  incurring a loss of $27,076 on the sale. Gallatin  Resources,  Inc.,
yet another  wholly-owned  subsidiary  was dissolved in December,  1994 with the
remaining assets and liabilities being distributed to the Company.

         The Company  explored  for and  developed  oil and gas  reserves in the
Mid-Continent  region of the United States. The majority of the Company's proved
developed reserves were located in Caddo,  Custer, Ellis and Kingfisher Counties
in Northwestern Oklahoma. The Company's exploration and production was conducted
for its own account. In 1996, the Company participated in no new wells. 1996 was
the second consecutive year that the Company saw no new revenue from oil and gas
production.  As of December 31, 1996 the Company was no longer actively  engaged
in the oil and gas industry.

         In August 1996,  Richard A. Green,  Sr. acquired control of the Company
through Verde,  Inc., a corporation he controlled.  At the time of the change in
control,  the Company had  experienced  more than 12 months of inactivity in the
oil and gas industry. The new Management decided that there was little realistic
hope of  profitable  operation  in the oil and gas industry  and  determined  to
explore  new  business  opportunities  in an  attempt  to bring  revenue  to the
Company.

         On  September  11, 1996,  as part of the new  research and  development
efforts,  the Company invested in a new restaurant  concept modeled upon certain
aspects of successful franchises. As part of this research, the Company obtained
items of restaurant supplies and equipment for $30,000.00,  and contributed them
to be used in the operation of the first store.  That  equipment was returned to
the Company upon the closure of the store. The Company contributed an additional
$8,550.00  in  cash  to  assist  in  various  aspects  of the  operation  of the
restaurant  before  making the decision to reject the  opportunity  as not being
viable for the Company.  The Company decided that the new restaurant concept was
not appropriate for the Company and decided to liquidate the investment.

         In a further  attempt to find new revenue for the Company,  on November
6,  1996,  the  Company  invested  $1,000  dollars  in  the  establishment  of a
wholly-owned subsidiary, Crescent Contractors, Inc., in the State of Texas. This
subsidiary  was formed for the  purpose of seeking and  developing  new lines of
business,  particularly in the commercial construction industry. On November 27,
1996,  Crescent  Contractors,  Inc. entered into a Motel Construction  Agreement
with AmeriTel,  Inc., for the  construction  of a motel facility in Gainesville,
Texas.  Crescent  Contractors,  Inc.  simultaneously  entered  a  Joint  Venture
Agreement  with Rustown  Homes,  Inc. This  agreement  provided for only nominal
participation  by Rustown and a final  distribution  to Rustown of One  Thousand
Dollars ($1,000) upon completion of the project as its share of any profit.  The
Joint Venture  agreement was  considered  necessary and was designed to reassure
AmeriTel by including a company with an operating  history in the project  while
allowing Crescent Contractors, Inc. to build a history as an operating business.

         On or about July 21, 1997, Richard A. Green, Sr., ceased to control the
Company. Verde, Inc. sold its holdings to Richard Bowes and Joe R. Love, and Mr.
Green resigned all positions with the Company.

     In March 1997, the Company sold all remaining items of restaurant equipment
it owned to Food Franchises,  Inc. for an extension of credit of $37,448.00 Food
Franchises,  Inc. was an  affiliate  Richard A. Green,  Sr. On July 7, 1997,  in
connection with the sale of Mr. Green's control, the Company sold the $37,448.00
receivable to Verde,  Inc., in exchange for the assumption of liabilities of the


                                       4

<PAGE>

Company  in the  amount of  $25,636.00.  The  Company  recognized  a loss on the
transaction  of  $11,812.00.  See "Item  12. Certain  Relationships  and Related
Transactions."

         Also, in connection with the sale of Mr. Green's control,  the Company
sold its wholly owned subsidiary,  Crescent Contractors, Inc., to Rustown Homes,
Inc. on June 11,  1997,  for  $414.00.  At the same time,  the Company  sold its
wholly owned subsidiary Cresthaven,  Inc. to Crestmont  International,  Inc. for
$414.00.  In  each  case,  the  amount  of the  consideration  constituted  full
reimbursement  to  the  Company  of  all  expenditures  paid  on  behalf  of the
subsidiary.  In  addition,  in each case the buyer was owned or partly  owned by
Richard  A.  Green,  Sr. No gain or loss was  realized  by the  Company on these
sales.

         Therefore,  at December 31, 1997,  the Company had only nominal  assets
and no active business operations.

Canadian Regulation

         The Company  does not believe that it is subject to the  provisions  of
Investment  Canada Act ("ICA")  because as of December 31, 1996,  it has not had
any  employees  in Canada for at least two years and did not maintain a business
establishment  in  Canada  which  would  cause it to be  considered  a  Canadian
business  enterprise  subject  to ICA.  The  Company  does not plan to alter its
contacts with Canada and,  therefore,  believes that ICA will continue not to be
applicable to the common stock of the Company and the  acquisition  thereof by a
non-resident or non-citizen of Canada.  However, in the event that management of
the Company should, for whatever reason, decide that it is in the best interests
of the Company to hire  employees in Canada,  lease  office space in Canada,  or
acquire oil and gas  properties in Canada,  the Company would probably be deemed
to be a Canadian business enterprise and ICA would be applicable.

Employees

         As of December 31, 1997, the Company had no full-time employees.

Recent Acquisition

         As  discussed  above,  the Company  acquired  80% of PhyMed on April 3,
1998.  In  connection  with the  acquisition,  a change of control  occurred and
George C. Barker became the controlling  shareholder of the Company.  Mr. Barker
filed a Schedule  13D with the  Commission  on April 13,  1998,  and the Company
filed a Form 8-K on April 20, 1998, to report these events.

         PhyMed's  Present  Business  and  Contemplated  Growth.   PhyMed  is  a
seven-year-old  company  engaged  in the  operation  and  management  of medical
diagnostic  imaging  centers,  which provide a full scope of medical  diagnostic
imaging services  including  magnetic  resonance  imaging (MRI),  computer axial
tomography (CAT) scans,  x-rays and other  radiological  services to physicians.
Currently, PhyMed owns and operates a diagnostic imaging center (the "Center" or
the "Dallas Center") in Dallas,  Texas,  which provides  diagnostic  services to
physicians in the greater Dallas area. The Dallas Center occupies  approximately
13,000 square feet in leased premises.  PhyMed also manages an imaging center in
Plano, Texas for other owners.

                                       5

<PAGE>


          Prior to the acquisition,  PhyMed was a privately-held company and the
transaction  with PhyMed was undertaken as part of an overall plan for expanding
the business of PhyMed through, among other possible endeavors,  the development
of new centers,  acquisitions  of existing  centers and commencing and expanding
the  use  of  exclusive  capitated  services  contracts,  with  a  view  towards
increasing  the  per-share   value  of  the  Company  for  the  benefit  of  the
shareholders.  There is no assurance  any of these  expansion  efforts will take
place or that, if undertaken,  they will be undertaken on terms favorable to the
Company, will be continued, or will be profitable.

         PhyMed  also  has  plans  to  establish  a  radiological   professional
practices  division and a capitated services division to market its radiological
services  to  self-insured   corporations,   health  maintenance  organizations,
preferred  provider  organizations  and  insurance  companies;  and a  physician
practice management and services division. There is no assurance either of these
divisions will become actual  business  operations,  or that, if commenced,  any
such business  operations  will be conducted on terms  favorable to the Company,
will be continued, or will be profitable.

         This expansion will require additional capital,  and the managements of
the Company  and PhyMed  believe  that  raising  additional  capital can best be
achieved  through PhyMed having access to the public  shareholders and reporting
company  status under the  Securities  Exchange  Act of 1934,  which the Company
affords.

         In  furtherance  of  this  goal  of  raising   additional  capital  for
expansion,  the Company has recently  commenced a private offering of securities
to accredited  investors only. The offering seeks to raise a minimum of $200,000
and a  maximum  of  $3,000,000  from the  sale of  Units  of a new  Series B 12%
Convertible Preferred Stock and Warrants to purchase Common Stock.

Item 2.  Description Property

         At  December  31,  1997,  the  Company  did  not  own  or  operate  any
properties.

Item 3.  Legal Proceedings

         At December 31, 1997,  the Company was not a party to any pending legal
proceedings.

Item 4.  Submission of Matters to a Vote of Security Holders

          No matter  was  submitted  to a vote of  security  holders  during the
fourth (last) quarter of the fiscal year ended December 31, 1997.

         The  Company  has not  paid  any  dividends  on its  Common  Stock  and
anticipates  that future  earnings,  if any, will be retained to finance  future
growth.  In addition,  the 135,139 shares of Series "A" Preferred  Stock have an
annual  noncumulative  dividend  preference  of  $6,757  (5% of Can.  $135,139).
Accordingly,  the Company  does not  anticipate  paying any  dividends on Common
Stock for the foreseeable future.

         The Company is not aware of any limitations on the rights of foreigners
to hold or vote its securities, save and except the potential application of the
Foreign Investment Review Act of Canada (the "ICA").

         The Company  does not believe that it is subject to the  provisions  of
ICA,  because,  as of December 31, 1997, it did not have any employees in Canada
and did not maintain a business  establishment in Canada which would cause it to
be considered a Canadian  business  enterprise  subject to ICA. The Company does
not plan to alter its contacts  with Canada and,  therefore,  believes  that ICA
will  continue not to be  applicable  to the Common Stock of the Company and the


                                       7

acquisition thereof by a non-resident or non-citizen of Canada.  However, in the
event that Management of the Company should, for whatever reason, decide that it
is in the best  interests  of the  Company to hire  employees  in Canada,  lease
office  space in Canada,  or acquire  properties  in Canada,  the Company  would
probably  be  deemed  to be a  Canadian  business  enterprise  and ICA  would be
applicable.

         Within  the past  three  years,  the  Company  has  sold the  following
securities without registering under the Securities Act:

          (a)  During  1997,  Messrs.  Joe R.  Love,  Joe P. Foor and an outside
               consultant,  Richard Bowes,  rendered  services to the Company in
               connection  with  Board  meetings  and,  specifically,   for  due
               diligence efforts regarding merger  candidates.  In consideration
               of such  services,  on October 16,  1997,  the Board of Directors
               authorized, in general, the issuance of an aggregate of 3,000,000
               shares,  as presently  constituted,  to such  persons  (1,000,000
               shares to each of such persons). Effective December 31, 1997, the
               Board of Directors  authorized the Company to treat the shares as
               having  been earned in full and deemed to be issued on such date.
               The Common Stock was trading at approximately  $0.06 per share on
               such date.  The  shares  were  valued at $0.02 per share,  on the
               basis of the  market  value of the  stock,  discounted  for being
               "restricted  securities"  and lack of  liquidity,  as well as the
               Company's lack of earnings and book value.  See "Item 12. Certain
               Relationships and Related Transactions."

               The issuance of these shares was exempt under Section 4(2) of the
               Securities  Act.  These shares were issued to persons who were at
               the time a principal  shareholder of the Company (Mr.  Bowes) and
               two Directors (Messrs. Love and Foor), one of whom (Mr. Love) was
               also a principal  shareholder  of the Company.  Such persons have
               access to  information  concerning the Company and the ability to
               fend for  themselves.  In  addition,  they  took the  shares  for
               investment.

          (b)  On April 3, 1998,  the Company  issued by  operation  of law in a
               reverse  triangular  statutory  merger  certain  shares of Common
               Stock in a business  combination.  The Company acquired ownership
               of 80% of Phy.Med.,  Inc. in the merger.  In connection  with the
               merger, George C. Barker,  individually,  and the Phy.Med.,  Inc.
               Employee  Stock  Ownership  Plan (the "ESOP"),  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
               outstanding,  would constitute 87.9% of the 78,430,965  shares of
               Common Stock the Company would then have  outstanding.  See "Item
               11.  Security   Ownership  of  Certain   Beneficial   Owners  and
               Management."

               The issuance of these shares is exempt under  Section 4(2) of the
               Securities  Act.  The  Company  is  issuing  these  shares  to  a
               sophisticated  investor.  In addition,  Mr.  Barker has access to
               information  concerning  the  Company and the ability to fend for
               himself.  He and the ESOP, of which he is the sole  trustee,  are
               taking the shares for investment.

          (c)  Effective  December 31, 1997,  the Board of Directors  authorized
               the  Company to issue to Joe P. Foor  1,000,000  shares of Common
               Stock,  as presently  constituted  (which will be 100,000,  after
               giving effect to a proposed  1-for-10 reverse stock split),  as a
               finder's  fee for his  services  in  introducing  the Company and
               Phy.Med.,   Inc.,  and  assisting  in  the   consummation  of  an
               acquisition  of PhyMed,  such shares to be  issuable  only in the
               event of the consummation of a business  combination  transaction
               whereby the Company  acquires  Phy.Med.,  Inc. On such date,  the
               Common  Stock was trading at about $0.06 per share (or  $20,000).
               The 1,000,000 shares were valued at $0.02 per share, on the basis
               of  the  market  value  of  the  stock,   discounted   for  being
               "restricted  securities"  and lack of  liquidity,  as well as the
               Company's  lack of earnings  and book value.  The Company  became
               obligated to issue such  1,000,000  shares of Common Stock to Joe
               Foor for his services  when the merger  transaction  which became
               effective  on April 3,  1998,  and the  shares are deemed to have
               been issued on such date.

               The issuance of these shares will be exempt under Section 4(2) of
               the  Securities  Act. These shares are being issued to a Director
               of the Company. Such person has access to information  concerning
               the Company and the ability to fend for himself. In addition,  he
               will take the  shares  for  investment.  See  "Item 11.  Security
               Ownership of Certain Beneficial Owners and Management."

          (d)  Effective  May 4,  1998,  the Board of  Directors  granted  stock
               options to Messrs. Barker, Love and Foor, subject to the approval
               of the shareholders. Each of the options is subject to a separate
               stock  option  agreement  and is not  part of a plan.  The  three
               options are exercisable to purchase a total of 10,000,000  shares
               of the Company's  Common Stock at $0.075 per share,  as presently
               constituted  (1,000,000  shares  at $.75  per  share,  after  the
               effectiveness of the 1-for-10 reverse stock split).

               Mr. Barker's option is exercisable to purchase  5,000,000  shares
               of Common Stock, as presently  constituted (500,000 shares, after
               the  effectiveness  of the 1-for-10  reverse  stock  split).  The
               option  is not  immediately  exercisable.  It vests  and  becomes
               exercisable  in full at the end of any quarter  during any fiscal
               year  when the  cumulative  "Operating  Profit  Before  Corporate
               Overhead"  for  such  fiscal  year  to  date  equals  or  exceeds
               $1,065,483.

               Mr.  Barker's option has a term of 10 years and expires on May 4,
               2008.  The purpose of Mr.  Barker's stock option is to retain and
               incentivise  him as  Chairman of the Board,  President  and Chief
               Executive Officer of the Company.

               The options granted to Mr. Love and Mr. Foor are each exercisable
               to purchase 2,500,000 shares, as presently  constituted  (250,000
               shares,  after the  effectiveness  of the 1-for-10  reverse stock
               split).  Each option can be  exercised in whole or in part at any
               time after the effectiveness of the 1-for-10 reverse stock split,
               has a term of 10 years and expires on May 4, 2008. The purpose of


                                       9

<PAGE>


               the options  granted to Mr.  Love and Mr.  Foor is to  compensate
               them for serving as Directors of the Company.

               The grant of the options  was exempt  under  Section  4(2) of the
               Securities Act. These options were granted to the three Directors
               of the Company,  one of whom is also the Chief Executive  Officer
               of  the  Company.   The  optionees  have  access  to  information
               concerning the Company and the ability to fend for themselves. In
               addition,  the  optionees  took the options for  investment.  The
               issuance of the  underlying  shares of Common Stock upon exercise
               of the  options  will  likewise  be exempt  for the same  reason.
               However, the Company plans to register the shares of Common Stock
               underlying  the options on Form S-8 whenever  anyone of the three
               optionees advises the Company that he would like to exercise part
               or all of his option. See "Item 10. Executive Compensation."

Item 6.  Management's Discussion and Analysis or Plan of Operation.

         (a) Plan of Operation.

         The Company had no revenue from operations in 1997 or 1996. At December
31,  1997,  the Company has only  nominal  assets,  no  liabilities,  no current
business  operations and no employees.  The Company's  total assets  consists of
$116 cash.  The Company  will  continue to depend on present  management  as its
major  source of  liquidity,  as it has no unused  line of credit or any  formal
arrangements with any lending institution to borrow any funds.

         During 1996 and 1997,  former and present  management  has engaged in a
process of seeking out new business  opportunities  for the company.  As part of
this process,  they met with several investment bankers and broker-dealers in an
effort to generate  interest in  conducting a public  offering of the  Company's
securities.  However,  as of December 31, 1997 such discussions had not resulted
in an agreement for such offering.  July of 1997 brought a change in management,
but no public  offering was  successfully  undertaken.  As of December 31, 1997,
management  has been unable to secure  additional  financing  through the public
market.  Nonetheless,  the Company  will  continue  to seek out and  investigate
opportunities which are presented through the contacts of present management.

         As of  December  31,  1997,  the  Company's  future  efforts  to obtain
additional  capital may include efforts to conduct a public or private  offering
of the Company's  equity  securities,  as well as proposed  acquisitions of real
estate  properties  in exchange for Common Stock of the  Company.  However,  the
Company  will wait until more  details  are  available  for review and  analysis
before  making a final  decision in this matter.  In the opinion of the Company,
due to its lack of substantial  current assets,  it is possible that the Company
may have to issue additional equity or debt instruments,  including  substantial
blocks of  common  stock,  in order to  complete  a  transaction  involving  the
development of any new business operations.  In addition,  although there are no
formal  plans to  purchase  significant  properties  or  equipment,  the Company
considers  it likely  that an issuance  of equity or debt  instruments  would be
necessary to secure any new assets.  At December 31, 1997,  the Company does not
have enough details to form a formal plan.

<PAGE>


         During  1997,  Messrs.  Joe  R.  Love,  Joe  P.  Foor  and  an  outside
consultant, Richard Bowes, rendered services to the Company, partly for services
rendered in connection  with Board meetings and partly for  consulting  services
consisting  of  due  diligence   efforts   regarding   merger   candidates.   In
consideration  of such  services,  on October 16,  1997,  the Board of Directors
authorized  the  issuance of an  aggregate  of  3,000,000  shares,  as presently
constituted,  to such persons  (1,000,000  shares to each of such persons).  The
Company  treated  the shares as having been earned in full and issued at the end
of the year,  December 31, 1997. The Company valued such services at $60,000 and
recorded  that  amount as an expense for 1997.  The Common  Stock was trading at
approximately  $0.06 per share on December 31,  1997.  The shares were valued at
$0.02 per share,  on the basis of the market value of the stock,  discounted for
being  'restricted  securities" and lack of liquidity,  as well as the Company's
lack of earnings and book value.

         Effective  April  3,  1998,  pursuant  to  an  agreement  and  plan  or
reorganization and merger, between the Company and Phy.Med.,  Inc. (PhyMed), the
Company acquired 80% of the outstanding  capital stock of PhyMed in exchange for
68,915,409  shares of common  stock.  The  merger,  which  results in the former
PhyMed shareholders  owning  approximately 87.9% of the outstanding Common Stock
of the Company,  will be accounted for as a reverse  acquisition  whereby PhyMed
will be deemed to the acquiring company.

         Unaudited financial information for PhyMed as of December 31, 1997, and
for the year then ended is presented below:

                      Total assets                            $5,210,032
                      Stockholders' equity                    $  203,554
                      Net revenue                             $3,884,043
                      Net earnings                            $  183,348

         PhyMed has 30 full-time  employees,  none of whom is  represented  by a
labor union. PhyMed considers its employee relations to be good.

Directors

         The  shareholders  elected three  Directors at the  last Annual Meeting
of Shareholders on July 15, 1997. The three Directors were Messrs.  Joe R. Love,
Joe P. Foor and  Richard A. Green,  Sr. Mr.  Green  resigned  as a Director  and
officer  of the  Company  on July 21,  1997,  in  connection  with the sale of a
controlling  interest in the Company beneficially owned by him. George C. Barker
was elected as a director on April 3, 1998,  in connection  with the Merger,  to
fill  the  existing  vacancy.  The term of the  present  directors  will  expire
concurrently  with the  election of  directors  at the  forthcoming  1998 Annual
Meeting of Shareholders.

         Management  will  propose  that  Messrs.   Barker,  Love  and  Foor  be
re-elected  as  Directors  for the coming  year at the  forthcoming  1998 Annual
Meeting of Shareholders  and that two additional  Directors be elected;  namely,
Marilyn  Moss and Judith F.  Barker.  George C.  Barker and Judith F. Barker are
married.

         The Company's Certificate of Incorporation  provides that the number of
Directors  shall be as specified in the Bylaws,  and the Bylaws provide that the
number of Directors  shall be not less than one nor more than seven.  The Bylaws
further provide that the  shareholders  may at any annual meeting  determine the
number of  Directors,  and the number so  determined  shall  remain  fixed until
changed  at a  subsequent  annual  meeting.  The  present  number of  authorized
Directors is three, and management proposes to enlarge the Board of Directors to
five members.

         Each  Director  elected  at the  forthcoming  1998  Annual  Meeting  of
Shareholders  will serve until the next Annual Meeting of Shareholders and until
his or her successor has been duly elected and qualified.

         During the last three fiscal years, neither the Chief Executive Officer
of the  Company,  nor any  executive  officer,  received  any  cash  or  noncash
compensation  for serving in such capacity.  During fiscal 1997, no options were

         In 1993,  PhyMed and Mr.  Barker  entered  into a  ten-year  employment
Merger  pursuant  to which  PhyMed  pays  Mr.  Barker  $240,000  per  annum.  In
connection  with the Merger,  on April 3, 1998 Mr.  Barker became an employee of
the  Company  and the  Company  assumed  the  obligations  of  PhyMed  under the
employment Merger.

         During the fiscal year ended  December 31,  1997,  George C. Barker was
the Chief Executive  Officer of PhyMed and the only executive  officer of PhyMed
whose total compensation  exceeded $100,000.  PhyMed paid or accrued $240,000 of
salary to Mr. Barker during such period.

         On May 4, 1998,  the Board of  Directors  of the  Company  granted  Mr.
Barker an option to purchase  5,000,000  shares of Common  Stock,  as  presently
constituted  (500,000  shares after the  effectiveness  of the 1-for-10  reverse
stock split),  with vesting to be contingent  upon the attainment by the Company
of certain financial objectives.  For additional information,  see "Stock Option
Grants" below.

Compensation of Directors

         Messrs. Joe R. Love and Joe P. Foor were compensated for their services
as Directors  during 1997 in shares of Common Stock.  Such shares were issued as
part of a block  of stock  issued  to them and an  outside  consultant,  Richard
Bowes,  for services  rendered to the Company,  partly for services  rendered in
connection with Board meetings and partly for consulting  services consisting of
due diligence efforts regarding merger candidates. This transaction is described
in detail in "Item 12. Certain Relationships and Related Transactions."

         On May 4, 1998, the Board of Directors granted to each Mr. Love and Mr.
Foor an option to  purchase  2,500,000  shares of  Common  Stock,  as  presently
constituted  (250,000  shares after the  effectiveness  of the 1-for-10  reverse
stock split).  The purpose of the options granted to Mr. Love and Mr. Foor is to
compensate  them  for  serving  as  Directors  of the  Company.  For  additional
information, see "Stock Option Grants" below.

1998 Stock Option Grants

         Effective May 4, 1998, the Board of Directors  granted stock options to
Messrs. Barker, Love and Foor, subject to the approval of the shareholders. Each

                                       15

<PAGE>

of the options is subject to a separate  stock option  agreement and is not part
of a plan.  The three options are  exercisable to purchase a total of 10,000,000
shares  of the  Company's  Common  Stock  at  $0.075  per  share,  as  presently
constituted  (1,000,000 shares at $.75 per share, after the effectiveness of the
1-for-10 reverse stock split).

         Mr.  Barker's  option is  exercisable to purchase  5,000,000  shares of
Common Stock, as presently  constituted (500,000 shares, after the effectiveness
of the 1-for-10 reverse stock split). The option is not immediately exercisable.
It vests and becomes  exercisable  in full at the end of any quarter  during any
fiscal year when the cumulative "Operating Profit Before Corporate Overhead" for
such fiscal year to date equals or exceeds $1,065,483.

         Mr.  Barker's option has a term of 10 years and expires on May 4, 2008.
The purpose of Mr.  Barker's  stock option is to retain and  incentivise  him as
Chairman of the Board, President and Chief Executive Officer of the Company.

         The options  granted to Mr. Love and Mr. Foor are each  exercisable  to
purchase 2,500,000 shares, as presently  constituted  (250,000 shares, after the
effectiveness of the 1-for-10 reverse stock split). Each option can be exercised
in whole or in part at any time after the  effectiveness of the 1-for-10 reverse
stock split,  has a term of 10 years and expires on May 4, 2008.  The purpose of
the options  granted to Mr. Love and Mr. Foor is to compensate  them for serving
as Directors of the Company.

         The number of shares  subject  to an option is subject to  proportional
adjustment  for any  increase or decrease in the number of shares  issued by the
Company  without  receipt  of  consideration  by the  Company,  such  as a stock
dividend or a stock split.

         The options are non-qualified  stock options under the Internal Revenue
Code of 1986.  As a general  rule,  no tax is imposed on the  optionee  upon the
grant of an option,  nor will the  Company be  entitled  to a tax  deduction  by
reason of such grant.  Generally,  upon the  exercise of an option,  an optionee
will be treated as receiving compensation taxable as ordinary income in the year
of  exercise in an amount  equal to the excess of the fair  market  value of the
shares on the date of  exercise  over the  exercise  price.  Thereafter,  if the
holder holds the stock for a period of one year or less the sale will be treated
as subject to ordinary income tax rates.  Stock held for a period  exceeding one
year receives capital gain tax rate treatment. The Company will be entitled to a
tax deduction in an amount equal to the compensation recognized by the optionee.

         Set forth  below is certain  information  with  respect to the  options
granted  as of  May  4,  1998,  subject  to  approval  of  the  options  by  the
shareholders.

(1)      Mr. Barker's option vests and becomes exercisable in full at the end of
         any  quarter  during any  fiscal  year when the  cumulative  "Operating
         Profit Before  Corporate  Overhead" for such fiscal year to date equals
         or exceeds $1,065.483.

(2)      Vested  immediately  upon the date of grant,  May 4,  1998,  subject to
         approval of the stock options by the shareholders of the Company at the
         Annual Meeting.

(3)      The option price is $0.075 per share,  as the Common Stock is presently
         constituted  ($0.75 per share,  after the effectiveness of the 1-for-10
         reverse  split).  The  dollar  value of the  option is equal to (a) the
         value of one share of Common  Stock in  excess  of  $0.075  per  share,
         multiplied by (b) the number of shares covered by the option. On May 4,
         1998,  the date the options were  granted,  the bid and asked prices on
         the Common Stock were approximately $0.15 and $0.30. However,  there is
         no established  trading  market in the Common Stock,  and trades of the
         Common  Stock  take place only  sporadically.  Therefore,  the Board of
         Directors has determined that the fair market value of the Common Stock
         on such date was $0.075,  as the Common Stock is presently  constituted
         ($0.75 per  share,  after the  effectiveness  of the  1-for-10  reverse
         split). Accordingly, the dollar value of the option is zero.

Vote Required for Ratification and Approval of the Stock Options

         The stock  option  agreements  must be  ratified  and  approved  by the
affirmative  vote of the holders of a majority of the shares of Common  Stock of
the Company  present in person or represented by proxy at the  forthcoming  1998
Annual Meeting of Shareholders. As of June 1, 1998, Mr. Barker owns of record or
beneficially  39,583,513 (80.17%) of the 49,099,069 outstanding Common Shares of
the  Company  and has  informed  the  Company  that he  intends  to vote all the
39,583,513 shares beneficially owned by him in favor of such proposal.

PhyMed Employee Stock Ownership Plan

         In 1993,  PhyMed  established an employee stock ownership plan ("ESOP")
for its employees.  Such plan is qualified  under the provisions of the Internal
Revenue  Code of 1986 as a defined  contribution  retirement  plan  designed  to
invest primarily in qualifying  employer  securities.  This provides a means for
employees to have an ownership interest in their employer.  Upon  establishment,
the ESOP purchased  certain shares of PhyMed from a shareholder  for a cash down
payment  and  a   promissory   note  payable  in   installments.   PhyMed  makes
contributions  to the ESOP which enable it to make timely  payments of principal
and interest on its note to the former  shareholder.  Mr. and Mrs. Barker own in
the aggregate  approximately  70% of the vested interests of participants in the
ESOP.  See "Item  11.  Security  Ownership  of  Certain  Beneficial  Owners  and
Management-Possible Change of Control."

Section 16(a) Beneficial Ownership Reporting Compliance

         Section  16(a) of the  Securities  Exchange  Act of 1934 and the  rules
promulgated  thereunder  require that  directors and  executive  officers of the
Company and beneficial  owners of greater than 10% of the Company's Common Stock
file various  reports with the Securities and Exchange  Commission  (the "SEC").
The  Company has  reviewed  its files and does not find that any Forms 3, 4 or 5
were furnished to the Company during or with respect to 1997. Based on inquiries
made by or on behalf of the  Company,  Management  believes  that for the fiscal
year ended December 31, 1997, reports were not timely filed by Richard A. Green,
Sr./Verde, Inc. or by Messrs. Bowes and Love with respect to the sale of control
of the Company in July 1997, nor by Messrs. Bowes, Love and Foor with respect to
the  3,000,000  shares of Common  Stock the Board of  Directors  authorized  the
Company to issue to them on December 31, 1997,  for  services  during 1997.  See
"Item 12. Certain  Relationships and Related  Transactions" for a description of
these transactions.


Item 11. Security Ownership of Certain Beneficial Owners and Management

         The following table sets forth certain information, as of June 1, 1998,
concerning  the  beneficial  ownership  of  Common  Stock by all  Directors  and
nominees,  certain executive  officers,  all Directors and executive officers of
the Company,  as a group, and each person who beneficially  owns more than 5% of
the  49,099,069  outstanding  shares of Common  Stock,  $.001 par value.  Unless
otherwise indicated, each person named has sole voting and investment power over
the shares indicated.

</TABLE>

(1)      In  April  1998,  the  Board  of  Directors   authorized,   subject  to
         shareholder  approval,  a 1-for-10 reverse stock split,  which includes
         increasing the par value of the Common Stock from $.001 to $.01.

(2)      Includes 30,924,620 outstanding shares owned directly by Mr. Barker and
         8,658,893 outstanding shares owned by the Phy.Med., Inc. Employee Stock
         Option  Plan,  as to which Mr.  Barker is the sole trustee and has sole
         voting power.  Also includes  shares the Company is still  obligated to
         issue to Mr. Barker (22,915,544 shares) and the ESOP (6,416,352 shares)
         in  connection  with the Merger.  Such shares would have been issued at
         the time of the  Merger  but the  Company  did not  have the  necessary
         authorized but unissued  shares.  See "Proposed  1-for-10 Reverse Stock
         Split" below.  Mr. and Mrs.  Barker own in the aggregate  approximately
         70% of the vested interests of participants in the ESOP.

(3)      Does not include  shares which can be purchased  upon the exercise of a
         recently  granted stock option.  On May 4, 1998, the Board of Directors
         granted  Mr.  Barker an option to purchase  5,000,000  shares of Common
         Stock, as presently constituted (500,000 shares after the effectiveness
         of the 1-for-10  reverse  stock  split),  with vesting to be contingent
         upon the  attainment  by the Company of certain  financial  objectives.
         Therefore,  it is not presently exercisable and will not be exercisable
         within  the next 60 days.  For  additional  information,  see "Item 10.
         Executive Compensation-1998 Stock Option Grants."

(4)      George C. Barker and Judith F. Barker are  married.  Mr.  Barker is the
         owner of  record or has the  power to vote all the  outstanding  shares
         beneficially  owned  by  him.  Mrs.  Barker  is also  deemed  to be the
         beneficial  owner  of  the  same  shares.  Mrs.  Barker  disclaims  any
         beneficial  ownership  of shares held by Mr.  Barker as sole trustee of
         the ESOP but allocated to the accounts of ESOP participants  other than
         Mr. or Mrs. Barker.

         issuable  upon  conversion  of  Series  A  Preferred  Stock  held  by a
         corporation  controlled by Mr. Love, and (c) 2,500,000 shares which can
         be purchased upon the exercise of a recently granted stock option.  See

(6)      Includes  (a)  26,667  shares  issuable  upon  conversion  of  Series A
         Preferred  Stock held by Mr. Foor's wife,  Anne Foor, and (b) 2,500,000
         shares which can be purchased  upon the exercise of a recently  granted
         stock option.  See "Item 10. Executive  Compensation-1998  Stock Option
         Grants.'

(7)      Less than 1%.

         By virtue of his beneficial  ownership of Common Stock,  Mr. Barker may
be deemed to be a "parent"  of the  Company as such term is defined in the rules
and regulations of the Securities and Exchange Commission.

Contemplated 1-for-10 Reverse Stock Split

         In  connection  with the  Merger on April 3,  1998,  George C.  Barker,
individually,  the Phy.Med.,  Inc.  Employee Stock  Ownership Plan (the "ESOP"),
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  outstanding,  would  constitute 87.9% of the 78,430,965
shares of Common Stock the Company would then have outstanding.

         The  parties to the Merger  Agreement  contemplate  a 1-for-10  reverse
stock split  which will become  effective  shortly  after the annual  meeting of
shareholders.  Upon the  effectiveness of such reverse split, Mr. Barker and the
ESOP  will own  6,941,540  shares  of the  7,843,097  shares,  $.01  par  value,
outstanding  (7,933,190  shares on a fully  diluted  basis).  The  Company  will
continue to have 50,000,000 shares of Common Stock authorized.

         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  shareholders 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 Merger 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 shareholder approval.

         In summary, Mr. 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  outstanding  on the record  date.  Of such  number,  Barker,
individually,   received   30,924,620  shares   (approximately   63.8%)  of  the
outstanding  shares,  and the  ESOP  received  8,658,893  shares  (approximately
17.9%).


                                       20
<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,  87.9%  of the  Common  Stock  of the  Company.  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 Merger  Agreement  contemplate that the shareholders
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). 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.

Possible Change of Control

         Prior to the Merger on April 3, 1998,  there were 800 common  shares of
PhyMed outstanding, of which 500 were owned by Mr. 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 54,230,788 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 15,184,621 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 800  shares of PhyMed  owned by Barker  and the ESOP at the time of
the Merger  were  pledged  to Patrick  Alan  Luckett  ("Luckett")  to secure the
payment of (a) two promissory notes payable to the order of Luckett,  which were
issued to him as partial  payment for shares of PhyMed  purchased  from him, and
(b) a guaranty of such notes.

         On  September  21,  1993,   Barker  and  Luckett  owned  all  the  then
outstanding  common  shares of PhyMed,  Inc.,  each of them owning of 500 common
shares.  On such date Luckett sold 200 of his shares to PhyMed and 300 shares to
the ESOP. The sales were for cash and promissory  notes.  One note was issued by
PhyMed in the original  principal amount of $800,000  pursuant to the terms of a
Loan and Security  Merger dated  September 21, 1993,  and the second  promissory
note was issued by the ESOP in the original  principal amount of $800,000.  Both
notes were  guaranteed by Barker.  The PhyMed note was secured by the 200 shares
repurchased from Luckett by PhyMed;  the ESOP note was secured by the 300 shares
the ESOP purchased from Luckett; and the 500 shares already owned by Barker were
pledged to secure his guaranty of the two notes.

         The  aggregate  of  68,915,409  shares of Common  Stock of the  Company
received  and to be  received  by Barker  and the ESOP as a result of the Merger
have been and will be  substituted in the pledge for the 640 PhyMed shares which
were released from the pledge and converted  into such shares of Common Stock of
the Company.  The 20% of PhyMed still owned by the ESOP remains pledged for such
purpose.

         As of June 1, 1998, the unpaid principal balance on the PhyMed note was
$115,070, and the ESOP note was $363,601.

Item 12.  Certain Relationships and Related Transactions

         On or about  July 21,  1997,  Richard A.  Green,  Sr.,  controlled  the
Company through Verde,  Inc. It owned 2,051,136  shares of Common Stock, and Mr.
Green was a Director and  President  of the Company.  On or about July 21, 1997,
Verde, Inc. sold its holdings to Richard Bowes and Joe R. Love for $50,000 cash,
and Mr. Green resigned all positions with the Company.

         In connection with the  sale  of  control, the  Company sold its wholly
owned subsidiary, Crescent Contractors, Inc., to Rustown Homes, Inc. on June 11,
1997,  for $414.00.  Also,  on the same date,  the Company sold its wholly owned
subsidiary  Cresthaven,  Inc. to Crestmont  International,  Inc. for $414.00. In
each case, the amount of the consideration constituted full reimbursement to the
Company of all expenditures  paid on behalf of the subsidiary.  In addition,  in
each case the buyer was owned or partly  owned by Richard A. Green,  Sr. No gain
or loss was realized by the Company on these sales.

         In  March 1997, the Company  sold all  remaining  items  of  restaurant
equipment  it owned to Food  Franchises,  Inc.  for an  extension  of  credit of
$37,448.00.  Food Franchises,  Inc. was an affiliate Mr. Green. On July 7, 1997,
in  connection  with the  sale of Mr.  Green's  control,  the  Company  sold the
$37,448.00  receivable  to  Verde,  Inc.,  in  exchange  for the  assumption  of
liabilities of the Company in the amount of $25,636.00. The Company recognized a
loss on the transaction of $11,812.00.

         During  the first six  months of the year  ending  December  31,  1997,
International  Green Team, Inc.  ("IGT") managed the Company under a monthly fee
arrangement.  IGT was an  affiliate  of Mr.  Green and provided the Company with
office space and managerial,  accounting and clerical services. The Company paid
IGT total fees of $15,600 and $24,000 for the years ended  December 31, 1997 and
1996.

         During  1997,  Messrs.  Joe  R.  Love,  Joe  P.  Foor  and  an  outside
consultant, Richard Bowes, rendered services to the Company, partly for services
rendered in connection  with Board meetings and partly for  consulting  services
consisting  of  due  diligence   efforts   regarding   merger   candidates.   In
consideration  of such  services,  on October 16,  1997,  the Board of Directors
authorized  the  issuance of an  aggregate  of  3,000,000  shares,  as presently
constituted,  to such persons  (1,000,000  shares to each of such persons).  The
Company  treated  the shares as having been earned in full and issued at the end
of the year,  December 31, 1997. The Company valued such services at $60,000 and
recorded  that  amount as an expense for 1997.  The Common  Stock was trading at
approximately  $0.06 per share on December 31,  1997.  The shares were valued at
$0.02 per share,  on the basis of the market value of the stock,  discounted for
being  "restricted  securities" and lack of liquidity,  as well as the Company's
lack of earnings and book value.

         On March 31, 1998, the Company entered into a letter agreement with Joe
P. Foor and CCDC, Inc., a company  controlled by Joe R. Love. Mr. Foor and CCDC,
Inc. (the "consultants") have agreed to provide certain specified consulting and
advisory  services  of a corporate  development  nature as the Company may need.
These include the  identification,  evaluation and negotiation of  acquisitions,
strategic  planning,  optimization  of  capital  structure,  access  to  capital
markets, and similar services.  The agreement is for a term of one year and will
continue after one year until terminated by either party upon 30 days' notice.

         The Company will pay the  consultants a $36,000 annual  retainer,  plus
out-of-pocket  expenses.  The  consultants  will also earn a transaction fee for
each  acquisition  or capital  placement  completed the Company  completes.  The
amount of the retainer will be credited  against any transaction  fees earned by
the  consultants.  The transaction fee will be based on the total amount paid by
the acquiring  party or the total capital  raised and will be a minimum of 3% of
such  transaction  amount.  If  greater  than 3%,  the  transaction  fee will be
determined by what is generally referred to as the "Lehman Formula," which is an
amount equal to the sum of:

         5% of the first  $1,000,000  of  transaction  amount;  
         4% of the second $1,000,000; 
         3% of the third $1,000,000;  
         2% of the fourth  $1,000,000; and 
         1% of the remainder of the transaction amount.

         The Company is currently  seeking to raise  additional  capital for the
expansion  of the  business  of  PhyMed  and has  recently  commenced  a private
offering  of  securities.   See  "Item  1.   Description  of  Business-   Recent
Acquisition." The offering is being made to accredited  investors only and seeks
to raise a minimum of $200,000 and a maximum of $3,000,000  from the sale of new
securities  that are  convertible  into or exercisable to purchase Common Stock.
The consultants will earn a transaction fee on any capital the Company raises in
this securities offering.

         George C. Barker owns a 50%  interest in and is  President  of American
Medical Imaging Corporation ("AMIC"), which operates a mobile magnetic resonance
imaging  ("AMRI") machine  in west  Dallas.  PhyMed  and  AMIC  have a  business
relationship  which is  embodied in a Radiology  Services  Provider  Agreement -
Contracted  Services dated February 1, 1996.  This agreement has a one year term
which renews  automatically  each year for one additional year unless terminated
by one of the parties. AMIC refers patients to PhyMed for MRI procedures AMIC is
unable to perform on its own MRI machine. PhyMed invoices AMIC directly for such
procedures  at a  discounted  fee of $300.00  per  procedure,  and AMIC pays the
invoices directly to PhyMed upon receipt. PhyMed received revenues of $40,191.25
from AMIC in 1997 and no revenues in 1996.

         Through PhyMed, the Company owns and operates PhyMed Diagnostic Imaging
Center in Dallas,  Texas.  PhyMed  entered  into a 10-year  Management/Licensing
Agreement with Medical Imaging of Plano,  Inc.  ("MIPI")  effective  January 14,
1998 with respect to the  operation of a new full  service  radiology  center in
Plano,  Texas, a suburb of Dallas,  under the name of "PhyMed Diagnostic Imaging
Center Plano." The Company manages the new center,  and licenses MIPI to use the
"PhyMed  Diagnostic  Imaging Center" name, in exchange for a monthly  management


                                       23


<PAGE>

fee of 3% of net sales.  Mr.  Barker owns 12.5% and is  President  of MIPI.  Mr.
Barker has personally  guaranteed for three years $200,000 of MIPI's obligations
under  equipment  leases  for  equipment  used at the new  center.  The  Company
contemplates  negotiating to acquire MIPI or the center.  However,  negotiations
have not yet begun,  and there is no assurance that such  acquisition  will take
place or, if it does, on terms that will be favorable to the Company.

         George  C.  Barker  d/b/a  "A/G  Partners"  manages  several  physician
practices for a monthly fee. PhyMed does not have a direct relationship with A/G
Partners.  One of the managed  practices is The PRS Group,  P.A.,  and Philip R.
Shalen, M.D. is the sole radiologist employed by it.

         On January 1, 1996,  PhyMed  and The PRS  Group,  P.A.  entered  into a
10-year  Radiology  Services  Agreement which provided that The PRS Group,  P.A.
would provide the  professional  service  component and PhyMed would provide the
technical component of the diagnostic  radiological  services rendered by PhyMed
at its Center.  PHYMed and The PRS Group, P.A. each bill patients separately for
their components of the diagnostic services.

         The 1996 Radiology Services Agreement also provided that The PRS Group,
P.A.  would provide  PhyMed with a Medical  Director who would  perform  certain
enumerated  services  for a fee of $6,500 per month.  Dr.  Shalen  served as the
Medical  Director from January 1, 1996,  until August 31, 1996, when the parties
terminated the position by mutual agreement.

         On September 1, 1997, the parties entered into a new 10-year  Radiology
Services Agreement which contains  substantially the same provisions as the 1996
agreement  except that it omits the provisions  providing for a Medical Director
and the remuneration associated with it.

         PhyMed paid the PRS Group, P.A. $58,500 in 1997 and $78,000 in 1996 for
the services of the Medical Director. The parties do not pay each other anything
under any of the provisions of the new 1997 agreement.

               Report of Independent Certified Public Accountants




Board of Directors
Tatonka Energy, Inc.


We have audited the  accompanying  balance sheet of Tatonka Energy,  Inc., as of
December 31,  1997,  and the related  statements  of  operations,  stockholders'
equity and cash flows for each of the two years in the period then ended.  These
financial  statements are the  responsibility of the Company's  management.  Our
responsibility  is to express an opinion on these financial  statements based on
our audits.

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

In our opinion,  the financial  statements  referred to above present fairly, in
all material  respects,  the financial  position of Tatonka Energy,  Inc., as of
December 31, 1997, and the results of its operations and its cash flows for each
of the two years in the period then ended in conformity with generally  accepted
accounting principles.

                          NOTES TO FINANCIAL STATEMENTS

                           December 31, 1997 and 1996




NOTE A - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    Nature of Operations
    --------------------

    The Company conducted oil and gas operations in the mid-continent  region of
    the United States until 1994 when it disposed of its oil and gas properties.
    The lack of oil and gas  related  operations  or revenue  since 1994 and the
    lack of any apparent  prospects for future income producing activity in that
    field  warranted  investigation  and  research  efforts  into new fields and
    industries. In November 1996, the Company entered into a contract to perform
    construction  services for a motel to be built in  Gainesville,  Texas,  but
    discontinued  this activity  (Note E). At December 31, 1997, the Company had
    no operations.

    Use of Estimates
    ----------------

    In preparing the company's financial  statements,  management is required to
    make estimates and  assumptions  that affect the reported  amounts of assets
    and liabilities,  the disclosure of contingent assets and liabilities at the
    date of the financial  statements,  and the reported amounts of revenues and
    expenses during the reporting period. Actual results could differ from those
    estimates.


NOTE B - LIQUIDITY MATTERS

    The Company has had losses in recent years,  and had only nominal  assets at
    December 31, 1997.  As discussed in Note H, the Company  acquired a business
    in exchange for common stock in April 1998.


NOTE C - INCOME TAXES

    Deferred income tax assets arose from the following temporary differences at
    December 31:

                                                            1997        1996
                                                           ------      -----

       Net operating loss carryforwards                 $ 121,300    $ 75,200
       Property and equipment                                  -        4,500
                                                              ---      ------
                                                          121,300      79,700
       Less valuation allowance                          (121,300)    (79,700)
                                                         --------     -------

       Net deferred tax asset                           $      -     $     -
                                                        =========    ========

    The Company has net operating loss  carryforwards of approximately  $310,000
    which will expire beginning in 2009.  However,  as a result of the Company's
    ownership change (Note H), use of these carryforwards will be limited.

NOTE C - INCOME TAXES - Continued

    A reconciliation  of income taxes computed at the federal  statutory rate to
income tax expense is as follows:

                                                                        1997              1996

                                                                     ========           =======

</TABLE>

NOTE D - PREFERRED STOCK

    The Company's  Series A convertible  preferred  stock is nonvoting and has a
    par value of $1. It has a 5% per annum noncumulative  dividend which is only
    payable if  declared  by the Board of  Directors.  Each  preferred  share is
    convertible into 6.6667 common shares.


NOTE E - RELATED PARTY TRANSACTIONS

    The Company sold its two  wholly-owned  subsidiaries  to a former officer of
    the Company for nominal  consideration in 1997. No gain or loss was realized
    by the Company on the sales.

    Entities  controlled  by  stockholders  with  controlling  interests  in the
    Company have provided office space and  managerial,  accounting and clerical
    services  to the  Company.  The  Company  incurred  fees for  such  services
    totaling $15,600 and $24,000 for the years ended December 31, 1997 and 1996,
    respectively.

    The Company is  obligated  to issue  3,000,000  restricted  shares of common
    stock,  valued at  $60,000,  to two  officers  of the Company and an outside
    consultant  for  consulting  services  provided to the Company in 1997.  The
    shares are  reflected as  outstanding  in the balance  sheet at December 31,
    1997.

    In 1997, the Company sold a $37,448  receivable to a corporation  controlled
    by the former  President of the Company for assumption of liabilities in the
    amount of  $25,636.  The Company  recognized  a loss on the  transaction  of
    $11,812.

                    NOTES TO FINANCIAL STATEMENTS - CONTINUED

                           December 31, 1997 and 1996




NOTE F - LOSS PER COMMON SHARE

    Loss per  common  share is based on the  weighted  average  number of common
    shares  outstanding  of 6,148,432  for 1997 and  5,515,556 for 1996 for both
    basic and diluted per share computations. Series A nonvoting preferred stock
    and common  stock  options are not  included  in the per share  computations
    because they are antidilutive.

    In the fourth quarter of 1997, the  Company  adopted  Statement of Financial
    Accounting  Standards   No.  128,  "Earnings  per  Share"  (SFAS  No.  128).
    Retroactive application,  which  is required by SFAS No. 128, did not result
    in a restatement of 1996 per share data.


NOTE G - STOCK OPTIONS

    The Company  granted  stock  options in July 1994 to certain  directors  and
    employees  to  purchase  550,000  shares of the  Company's  common  stock at
    approximately $.11 per share. The options were exercisable on or before July
    13,  1999,  subject  to  termination  clauses  in the  event  employment  or
    directorship ceases. No options have been exercised,  and all were cancelled
    and revoked in 1996.


NOTE H - MERGER AND PLAN OF REORGANIZATION

    Pursuant to an agreement and plan of  reorganization  and merger between the
    Company and Phy. Med., Inc. (Phy.  Med.),  the Company  acquired  80% of the
    outstanding capital stock of Phy. Med. in exchange for 69,415,409 shares  of
    common stock on April 3, 1998. The merger, which results in the former  Phy.
    Med.,  stockholders  owning  approximately  87.5% of the outstanding  common
    stock  of the  Company,  will be  accounted  for as  a  reverse  acquisition
    whereby Phy. Med. will be deemed to the acquiring company.

    Unaudited financial information for Ply Med. as of December 31, 1997, and 
    for the year then ended is presented below:

                  Total assets                        $5,210,032
                  Stockholders' equity                $  203,554
                  Net revenue                         $3,884,043
                  Net earnings                        $  183,348

                                GEORGE C. BARKER


This employment agreement ("Agreement") is made and entered into as of this date
by and between PHYMED, Inc., a Texas corporation ("Corporation"),  and GEORGE C.
BARKER, ("Executive").

WHEREAS,  the  Corporation  and  the  Executive  desire  that  the  term of this
Agreement begin on October 1, 1993; and

WHEREAS,  the Corporation desires to employ the Executive,  currently serving as
Chairman  of the  Board,  (which  position  he will  continue  to  hold)  as its
President  and Chief  Executive  Officer and Executive is willing to accept such
employment by the  Corporation,  on the terms and subject to the  conditions set
forth in this Agreement.

NOW THEREFORE, IT IS AGREED AS FOLLOWS:

Section 1. Duties. During the term of this Agreement, the Executive agrees to be
employed by and to serve the  Corporation  as its President and Chief  Executive
Officer,  and the Corporation  agrees to employ and retain the Executive in such
capacities.  In such  capacity,  the  Executive  shall  render such  managerial,
administrative and other services as are customarily associated with or incident
to such  position and shall perform such other duties and  responsibilities  for
the Corporation as the Corporation may reasonably require,  consistent with such
position. The Executive shall devote a substantial portion of his business time,
energy,  and skill to the  affairs of the  Corporation  as the  Executive  shall
report to the Corporation's board of directors.

The  Corporation  shall not appoint any  individual to whom the Executive  shall
report,  or who  shall  have the right to  supervise  the  Executive,  provided,
however,  that the  Corporation's  board of  directors  may  appoint one or more
members of the board of directors to coordinate the reporting from the Executive
to the  board of  directors.  In the  event  that the  Corporation  changes  the
Executive's   title,   working  conditions  or  specifies  duties  so  that  the
Executive's  powers and duties are  diminished  or reduced,  or include  powers,
duties or working  conditions which are not generally  consistent with the title
of  Chief  Executive  Officer,  or if  the  Corporation  changes  the  reporting
relationship so that the Executive reports to another officer or employee, other
than  the  Corporation's  board  of  directors  as a  whole,  then  at any  time
thereafter,  at the Executive's option and upon thirty days notice, and provided
that such changes shall not have been  rescinded or corrected to the  reasonable
satisfaction of the Executive within said thirty day period, the Executive shall
have the right to terminate the employment relationship,  and in such event, the
employment  shall be deemed to have been terminated by the  Corporation  without
cause.

                             STOCK OPTION AGREEMENT

                                George C. Barker

         Stock Option Agreement made this 4th day of May, 1998,  between Tatonka
Energy,  Inc.,  an  Oklahoma  corporation  ("Company")  and  George  C.  Barker,
("Optionee").

         WHEREAS,   The  Company   desires  to  provide  the  Optionee  with  an
opportunity  to acquire a  proprietary  interest in the  business of the Company
and, through stock ownership,  an increased  personal  interest in its continued
success and progress:

         NOW, THEREFORE,  in consideration of the premises, the mutual covenants
hereinafter set forth,  and other good and valuable  consideration,  the Company
and Optionee agree as follows:

         1. The Company  hereby grants to the Optionee the option to purchase an
aggregate of 5,000,000  shares of Company's  Common Stock,  par value of $0.0001
(as presently  constituted),  on the terms and conditions hereinafter set forth,
at the  purchase  price of $0.075 per share as  presently  constituted  (500,000
shares at $0.75 per share,  after the  effectiveness  of the  proposed  1-for-10
reverse stock split).

         2. The Option shall be  exercisable in whole or in part at any time, or
from  time to  time,  after  the  end of any  quarter  in  which  the  Company's
cumulative  operating  profits  (before  corporate  overhead)  exceed the sum of
$1,065,483  .  Notice  shall be given to the  Company  by the  Employee  of such
exercise of the Option as provided below.

         3. (a) The  Option  shall be  exercisable  as to not less  than  10,000
shares, as presently  constituted (1,000 shares,  after the effectiveness of the
proposed 1-for-10 reverse stock split), or a multiple thereof,  or the remaining
shares covered by the Option if less than such minimum. Notice shall be given to
the Company by the Optionee of such exercise of the Option as provided below.

                  (b) The  purchase  price of any  shares as to which the Option
shall be exercised shall be paid in full at the time of such exercise or, except
as  hereinafter  provided,  may,  at the  election of the  Optionee,  be paid in
installments,  in which case the first  installment shall be paid at the time of
such exercise. In the event that the purchase price of such shares shall be paid
in full at the time of such exercise,  such shares shall be issued as fully paid
and nonassessable  shares. In the event,  however, that the Optionee shall elect
to pay the purchase price of such shares in installments:

                  (i)  such shares shall be issued as partly paid and assessable
shares,

                  (ii) the first  installment  shall be amount equal to not less
than 20% of such purchase price,

                                       44



<PAGE>


                  (iii) the unpaid  balance of such purchase price shall be paid
(without interest) in equal installments, the first installment at the end of 12
months commencing with the date of such exercise and subsequent  installments at
the end of each successive  12-month  interval until the balance is paid in full
(the  Optionee  to have the  right of  prepaying  at any  such  time the  latest
maturing  installment  or  installments  of such purchase  price then  remaining
unpaid),  or may be prepaid in whole at any time,  provided,  however,  that any
unpaid balance of the purchase price shall be due and payable forthwith upon any
termination of the Option as hereinafter provided,

                  (iv) each installment paid in respect of such shares after the
first  installment  shall be applied to the  partial  payment of such  shares as
nearly as possible in an equal amount,

                  (v) such shares shall not be assigned or  transferred  (except
by will or operation of law) and the  certificates  issued therefor shall bear a
legend indicating that such share are not assignable or transferrable,

                  (vi) any  dividend  on the Common  Stock shall be paid on such
shares in direct  proportion to the  percentage of the purchase  price  therefor
which shall have been paid by the record date for such dividend,

                  (vii) each certificate for such shares shall, immediately upon
issue,  be  delivered  to the  Company,  endorsed  in blank by the  Optionee  or
accompanied by a separate stock power so endorsed, in pledge as security for the
unpaid  balance  of  the  purchase  price  of the  shares  represented  by  such
certificate,

                  (viii) such shares shall be subject to assessment  and call in
accordance  with the laws of the State of Texas;  further the Company shall have
the right,  by notice to that effect,  without the necessity of any such call or
assessment, to require the prepayment, in whole at any time or in part from time
to time of the unpaid  balance of the  purchase  price of such  shares or any of
them,  whether or not  prepayment  shall be required of any other person holding
partly paid shares, and

                  (ix) when the  balance of the  purchase  price of such  shares
which shall be represented by any certificate shall have been paid in full, such
certificate  shall  be  promptly  released  from  pledge,   stamped  full  paid,
nonassessable,  and transferable,  and delivered to the Optionee in person or my
certified mail, of if the Company so desires, such certificate shall be promptly
released from pledge and  surrendered to the Company,  and a new certificate for
full paid and nonassessable  shares shall be promptly  delivered to the Optionee
by certified mail in lieu thereof.

                  (c) In the event that there  shall be a default in the payment
when due hereunder of any installment, or of any call, assessment, or prepayment
required  by the  Company,  with  respect to any partly  paid  shares,  and such
default shall not be cured within thirty days after  written  notice  thereof by
the  Company,  the  Company  shall have the right to take such of the  following
actions as it shall deem desirable in its sole discretion:

                  (i) To cancel the Option and all other options  granted to the
Optionee under the Company's "Stock Option Agreement";


                                       45



<PAGE>


                  (ii) To take by  forfeiture  all right,  title,  and  interest
of the Optionee in and to such partly paid shares;

                  (iii) To (A) determine that the unpaid balance of the purchase
price of all partly paid shares issued hereunder is immediately due and payable,
without  further  demand or notice of any kind, in which case such balance shall
thereupon  be due and  payable;  (B)  sell,  as full  paid,  nonassessable,  and
transferable  shares,  all shares then  pledged  hereunder,  either at the Stock
Exchange or any public or private sale, without further notice or advertising of
any  kind,  and buy all or any part of such  shares  at such  sale free from any
right or equity of  redemption;  (C) charge the Optionee with the entire expense
of such sale; and (D) apply the proceeds of such sale against the balance of the
purchase price owed for all partly paid shares issued  hereunder and the expense
of such  sale,  with the  remainder,  if any,  to be paid over to the  Optionee;
provided,  however,  that if such proceeds  shall not be sufficient to liquidate
such balance and  expenses in full,  the  Optionee  shall  remain  liable to the
Company for any unliquidated portion of such balance and expense; and

                  (iv) To take such other action  (including  extending the time
for payment of such installment,  call,  assessment,  or prepayment) as shall be
permitted  by law.  The rights  granted  to the  Company  hereunder  shall be in
addition to and not in lieu of any other rights or remedies the Company may have
as a result of such default.

                  (d) Anything herein contained to the contrary notwithstanding,
the purchase price of any shares as to which the Option shall be exercised after
the  termination  of  the  Optionee's  employment  (by  retirement,   death,  or
otherwise)  shall be paid in full at the time of  exercise  of the  Option  with
respect to such shares.

         4. The Option may not be assigned,  transferred  (except as aforesaid),
pledged,  or hypothecated in any way (whether by operation of law or otherwise),
and shall not be subject to  execution,  attachment,  or  similar  process.  Any
attempted assignment,  transfer, pledge, hypothecation,  or other disposition of
the Option contrary to the provision  hereof,  and the levy of any attachment or
similar process upon the Option,  shall be null and void and without effect. The
Company shall have the right to terminate  the Option,  in the event of any such
assignment, transfer, pledge, hypothecation, other disposition of the Option, or
levy of  attachment or similar  process,  by notice to that effect to the person
then entitled to exercise the Option, provide,  however, that termination of the
Option  thereunder  shall not prejudice any rights or remedies which the Company
or a subsidiary corporation may have under this Agreement or otherwise.

         5. (a)  Subject  to the terms and  conditions  of this  Agreement,  the
Option shall be  exercisable  by notice to the  Company.  Each such notice shall
state the election to exercise the Option and the number of shares in respect of
which it is being exercised,

                  (ii) state  whether  the shares in respect of which the Option
is  being  exercised  are  being  paid  for in  full  or  will  be  paid  for in
installments,

                  (iii) be signed by the person or persons exercising the Option
and,  in the event that the Option is being  exercised  by any person or persons
other than the Optionee,  be accompanied by proof,  satisfactory  to counsel for
the Company, of the right of such person or persons to exercise the Option, and

                  (iv) be  accompanied  by a check  payable  to the order of the
Company  in an amount  equal to the  purchase  price of the shares in respect of
which the Option is being  exercised or the first  installment  of such purchase
price,  depending upon whether such shares are being paid for in full or will be
paid for in installments.

         The Option  shall not be deemed to have been  exercised  unless all the
preceding  provisions of this  paragraph  shall have been complied with, and for
all  purposes  of this  Agreement  the date of the  exercise  of the Option with
respect to any particular  shares shall be the date on which such notice,  proof
(if  required),  and  check  shall  have all been  mailed by  certified  mail or
delivered to the Company.  The certificate or certificates  for the shares as to
which the Option shall have ben so exercised  shall be registered in the name of
the persons or persons so  exercising  the Option and shall be  delivered  to or
upon the written  order of the person or persons  exercising  the Option  within
fifteen days after receipt by the Company of such notice,  proof (if  required),
and check. Such delivery shall be made at the office of the Company,  or at such
other place as the Company shall thereof have designated by notice.

                  (b) In the event that the  purchase  price of any shares as to
which the Option  shall be  exercised  shall be payable  in  installments,  each
installment  shall be  accompanied  by a notice to the Company of the payment of
such installment.

         6. Each  notice  relating  to this  Agreement  shall be in writing  and
delivered in person or by certified mail to the Company at its office, attention
of the Secretary. All notices to the Optionee or other person shall be delivered
to the Optionee or such other person or persons at the Optionee's  address below
specified.

                             STOCK OPTION AGREEMENT

                                   Joe R. Love

         Stock Option Agreement made this 4th day of May, 1998,  between Tatonka
Energy, Inc., an Oklahoma corporation ("Company") and Joe R. Love, ("Optionee").

         WHEREAS,   The  Company   desires  to  provide  the  Optionee  with  an
opportunity  to acquire a  proprietary  interest in the  business of the Company
and, through stock ownership,  an increased  personal  interest in its continued
success and progress:

         NOW, THEREFORE,  in consideration of the premises, the mutual covenants
hereinafter set forth,  and other good and valuable  consideration,  the Company
and Optionee agree as follows:

         1. The Company  hereby grants to the Optionee the option to purchase an
aggregate of 2,500,000  shares of Company's  Common Stock,  par value of $0.0001
(as presently  constituted),  on the terms and conditions hereinafter set forth,
at the  purchase  price of $0.075 per share as  presently  constituted  (250,000
shares at $0.75 per share,  after the  effectiveness  of the  proposed  1-for-10
reverse stock split).

         2. The Option shall be  exercisable in whole or in part at any time, or
from time to time,  upon  notice  given to the  Company by the  Optionee of such
exercise of the Option as provided below.

         3. (a) The  Option  shall be  exercisable  as to not less  than  10,000
shares, as presently  constituted (1,000 shares,  after the effectiveness of the
proposed 1-for-10 reverse stock split), or a multiple thereof,  or the remaining
shares covered by the Option if less than such minimum. Notice shall be given to
the Company by the Optionee of such exercise of the Option as provided below.

                  (b) The  purchase  price of any  shares as to which the Option
shall be exercised shall be paid in full at the time of such exercise or, except
as  hereinafter  provided,  may,  at the  election of the  Optionee,  be paid in
installments,  in which case the first  installment shall be paid at the time of
such exercise. In the event that the purchase price of such shares shall be paid
in full at the time of such exercise,  such shares shall be issued as fully paid
and nonassessable  shares. In the event,  however, that the Optionee shall elect
to pay the purchase price of such shares in installments:

                  (i)  such shares shall be issued as partly paid and assessable
shares,

                  (ii) the first  installment  shall be amount equal to not less
than 20% of such purchase price,






                                       50


<PAGE>


                  (iii) the unpaid  balance of such purchase price shall be paid
(without interest) in equal installments, the first installment at the end of 12
months commencing with the date of such exercise and subsequent  installments at
the end of each successive  12-month  interval until the balance is paid in full
(the  Optionee  to have the  right of  prepaying  at any  such  time the  latest
maturing  installment  or  installments  of such purchase  price then  remaining
unpaid),  or may be prepaid in whole at any time,  provided,  however,  that any
unpaid balance of the purchase price shall be due and payable forthwith upon any
termination of the Option as hereinafter provided,

                  (iv) each installment paid in respect of such shares after the
first  installment  shall be applied to the  partial  payment of such  shares as
nearly as possible in an equal amount,

                  (v) such shares shall not be assigned or  transferred  (except
by will or operation of law) and the  certificates  issued therefor shall bear a
legend indicating that such share are not assignable or transferrable,

                  (vi) any  dividend  on the Common  Stock shall be paid on such
shares in direct  proportion to the  percentage of the purchase  price  therefor
which shall have been paid by the record date for such dividend,

                  (vii) each certificate for such shares shall, immediately upon
issue,  be  delivered  to the  Company,  endorsed  in blank by the  Optionee  or
accompanied by a separate stock power so endorsed, in pledge as security for the
unpaid  balance  of  the  purchase  price  of the  shares  represented  by  such
certificate,

                  (viii) such shares shall be subject to assessment  and call in
accordance  with the laws of the State of Texas;  further the Company shall have
the right,  by notice to that effect,  without the necessity of any such call or
assessment, to require the prepayment, in whole at any time or in part from time
to time of the unpaid  balance of the  purchase  price of such  shares or any of
them,  whether or not  prepayment  shall be required of any other person holding
partly paid shares, and

                  (ix) when the  balance of the  purchase  price of such  shares
which shall be represented by any certificate shall have been paid in full, such
certificate  shall  be  promptly  released  from  pledge,   stamped  full  paid,
nonassessable,  and transferable,  and delivered to the Optionee in person or my
certified mail, of if the Company so desires, such certificate shall be promptly
released from pledge and  surrendered to the Company,  and a new certificate for
full paid and nonassessable  shares shall be promptly  delivered to the Optionee
by certified mail in lieu thereof.

                  (c) In the event that there  shall be a default in the payment
when due hereunder of any installment, or of any call, assessment, or prepayment
required  by the  Company,  with  respect to any partly  paid  shares,  and such
default shall not be cured within thirty days after  written  notice  thereof by
the  Company,  the  Company  shall have the right to take such of the  following
actions as it shall deem desirable in its sole discretion:

                  (i) To cancel the Option and all other options  granted to the
Optionee under the Company's "Stock Option Agreement";

                  (ii) To take by  forfeiture  all right,  title,  and  interest
of the Optionee in and to such partly paid shares;



                                       51


<PAGE>


                  (iii) To (A) determine that the unpaid balance of the purchase
price of all partly paid shares issued hereunder is immediately due and payable,
without  further  demand or notice of any kind, in which case such balance shall
thereupon  be due and  payable;  (B)  sell,  as full  paid,  nonassessable,  and
transferable  shares,  all shares then  pledged  hereunder,  either at the Stock
Exchange or any public or private sale, without further notice or advertising of
any  kind,  and buy all or any part of such  shares  at such  sale free from any
right or equity of  redemption;  (C) charge the Optionee with the entire expense
of such sale; and (D) apply the proceeds of such sale against the balance of the
purchase price owed for all partly paid shares issued  hereunder and the expense
of such  sale,  with the  remainder,  if any,  to be paid over to the  Optionee;
provided,  however,  that if such proceeds  shall not be sufficient to liquidate
such balance and  expenses in full,  the  Optionee  shall  remain  liable to the
Company for any unliquidated portion of such balance and expense; and

                  (iv) To take such other action  (including  extending the time
for payment of such installment,  call,  assessment,  or prepayment) as shall be
permitted  by law.  The rights  granted  to the  Company  hereunder  shall be in
addition to and not in lieu of any other rights or remedies the Company may have
as a result of such default.

                  (d) Anything herein contained to the contrary notwithstanding,
the purchase price of any shares as to which the Option shall be exercised after
the  termination  of  the  Optionee's  employment  (by  retirement,   death,  or
otherwise)  shall be paid in full at the time of  exercise  of the  Option  with
respect to such shares.

         4. The Option may not be assigned,  transferred  (except as aforesaid),
pledged,  or hypothecated in any way (whether by operation of law or otherwise),
and shall not be subject to  execution,  attachment,  or  similar  process.  Any
attempted assignment,  transfer, pledge, hypothecation,  or other disposition of
the Option contrary to the provision  hereof,  and the levy of any attachment or
similar process upon the Option,  shall be null and void and without effect. The
Company shall have the right to terminate  the Option,  in the event of any such
assignment, transfer, pledge, hypothecation, other disposition of the Option, or
levy of  attachment or similar  process,  by notice to that effect to the person
then entitled to exercise the Option, provide,  however, that termination of the
Option  thereunder  shall not prejudice any rights or remedies which the Company
or a subsidiary corporation may have under this Agreement or otherwise.

         5. (a)  Subject  to the terms and  conditions  of this  Agreement,  the
Option shall be  exercisable  by notice to the  Company.  Each such notice shall
state the election to exercise the Option and the number of shares in respect of
which it is being exercised,

                  (ii) state  whether  the shares in respect of which the Option
is  being  exercised  are  being  paid  for in  full  or  will  be  paid  for in
installments,

                  (iii) be signed by the person or persons exercising the Option
and,  in the event that the Option is being  exercised  by any person or persons
other than the Optionee,  be accompanied by proof,  satisfactory  to counsel for
the Company, of the right of such person or persons to exercise the Option, and



                                       52



<PAGE>


                  (iv) be  accompanied  by a check  payable  to the order of the
Company  in an amount  equal to the  purchase  price of the shares in respect of
which the Option is being  exercised or the first  installment  of such purchase
price,  depending upon whether such shares are being paid for in full or will be
paid for in installments.

         The Option  shall not be deemed to have been  exercised  unless all the
preceding  provisions of this  paragraph  shall have been complied with, and for
all  purposes  of this  Agreement  the date of the  exercise  of the Option with
respect to any particular  shares shall be the date on which such notice,  proof
(if  required),  and  check  shall  have all been  mailed by  certified  mail or
delivered to the Company.  The certificate or certificates  for the shares as to
which the Option shall have ben so exercised  shall be registered in the name of
the persons or persons so  exercising  the Option and shall be  delivered  to or
upon the written  order of the person or persons  exercising  the Option  within

and check. Such delivery shall be made at the office of the Company,  or at such
other place as the Company shall thereof have designated by notice.

                  (b) In the event that the  purchase  price of any shares as to
which the Option  shall be  exercised  shall be payable  in  installments,  each
installment  shall be  accompanied  by a notice to the Company of the payment of
such installment.

         6. Each  notice  relating  to this  Agreement  shall be in writing  and
delivered in person or by certified mail to the Company at its office, attention
of the Secretary. All notices to the Optionee or other person shall be delivered
to the Optionee or such other person or persons at the Optionee's  address below
specified.

         7.  Neither this Option nor the shares of Common  Stock  issuable  upon
exercise  hereof,  have been  registered  under the  Securities  Act of 1933, as
amended,  or any state securities laws. The Optionee,  by accepting this Option,
represents and warrants that he is acquiring this Option for his own account for
investment  and  not  with  a  view  to or  for  sale  in  connection  with  any
distribution  thereof except in conformity with the provisions of the Securities

and applicable  state  securities  laws, and further agrees that this Option may
not be sold or transferred in the absence of an effective registration statement

Company to the effect  that there is an  exemption  from such  registration.  In

any shares of Common Stock  purchased  upon the  exercise of this Option  unless
such shares have at the time of issuance been  registered  under the  Securities
Act of 1933, as amended,  and applicable  state securities laws, or the Optionee
can  demonstrate  the   availability  of  federal  and  state   exemptions  from
registration and qualification not requiring same.

Company for any unliquidated portion of such balance and expense; and

                  (iv) To take such other action  (including  extending the time

otherwise)  shall be paid in full at the time of  exercise  of the  Option  with
respect to such shares.

         4. The Option may not be assigned,  transferred  (except as aforesaid),
pledged,  or hypothecated in any way (whether by operation of law or otherwise),

attempted assignment,  transfer, pledge, hypothecation,  or other disposition of
the Option contrary to the provision  hereof,  and the levy of any attachment or
similar process upon the Option,  shall be null and void and without effect. The
Company shall have the right to terminate  the Option,  in the event of any such
assignment, transfer, pledge, hypothecation, other disposition of the Option, or
levy of  attachment or similar  process,  by notice to that effect to the person
then entitled to exercise the Option, provide,  however, that termination of the
Option  thereunder  shall not prejudice any rights or remedies which the Company
or a subsidiary corporation may have under this Agreement or otherwise.

Option shall be  exercisable  by notice to the  Company.  Each such notice shall

Company  in an amount  equal to the  purchase  price of the shares in respect of
which the Option is being  exercised or the first  installment  of such purchase
price,  depending upon whether such shares are being paid for in full or will be
paid for in installments.

         The Option  shall not be deemed to have been  exercised  unless all the
preceding  provisions of this  paragraph  shall have been complied with, and for
all  purposes  of this  Agreement  the date of the  exercise  of the Option with
respect to any particular  shares shall be the date on which such notice,  proof
(if  required),  and  check  shall  have all been  mailed by  certified  mail or

and check. Such delivery shall be made at the office of the Company,  or at such
other place as the Company shall thereof have designated by notice.

                  (b) In the event that the  purchase  price of any shares as to
which the Option  shall be  exercised  shall be payable  in  installments,  each
installment  shall be  accompanied  by a notice to the Company of the payment of
such installment.

         6. Each  notice  relating  to this  Agreement  shall be in writing  and
delivered in person or by certified mail to the Company at its office, attention
of the Secretary. All notices to the Optionee or other person shall be delivered
to the Optionee or such other person or persons at the Optionee's  address below

         7. Neither this Option nor the shares of  Common  Stock  issuable  upon
exercise  hereof,  have been  registered  under the  Securities  Act of 1933, as
amended,  or any state securities laws. The Optionee,  by accepting this Option,

Act of 1933, as amended,  and applicable  state securities laws, or the Optionee

This MANAGEMENT/LICENSING  AGREEMENT (this "AGREEMENT") is made and entered into

Manager deems appropriate in the operation of the Center.

their wages, fringe benefits or other compensation.  Center shall be responsible
for payment of the total  aggregate  compensation,  including  fringe  benefits,
payable  with  respect to such  employees.  The term  "fringe  benefits" as used
herein shall mean and include Center's contribution of FICA, FUTA,  unemployment
compensation and other employment taxes, worker's  compensation,  group life and

before the tenth (10th) day of the month following,  every month during the term
of this  AGREEMENT.  The  formula  for  determining  the  Management  Fee is not
intended and shall not be  interpreted  or applied as permitting  the Manager to
share in the  Center's  fees.  It is  acknowledged  as the  parties'  negotiated
AGREEMENT as to the  reasonable  fair market value of the services  furnished by
Manager  pursuant to this  AGREEMENT,  considering  the nature and volume of the
services required and the risks assumed by the Manager.

5. Payment of Expenses.  Center shall be  responsible  for making payment of all
operating  expenses  attributable  to the operation of Center unless  payment is
specifically assumed by Manager as an obligation pursuant to this AGREEMENT.

6. Performance of Duties of Manager.  (a) Manager is an independent  contractor,

Manager  shall not act or attempt to act, or in any manner  assume or create any
obligation  on behalf of or in the name of the Center or any of its  affiliates,
or otherwise bind the Center or any of its affiliates in any manner,  other than
as specifically  authorized in this AGREEMENT or otherwise authorized in writing
by the Center.

(b) Manager  shall devote its best  efforts to the  operation of the Center in a
reasonable  manner and shall  perform its  services  and  obligations  hereunder
diligently and according to the local  standards.  It is expressly  acknowledged

         4.03     Termination For Cause.

          (a)     Notwithstanding  any  other provision  of this Agreement,  the
                  AMIC  shall  have  the  right  to  terminate   this  Agreement
                  immediately  upon  the  occurrence  of any  of  the  following
                  events: (1) PHYMED ceases to have an unrestricted  license  to
                  practice,  an unrestricted DEA  authorization number, and  DPS
                  Registration;  (2) PHYMED  fails  to  maintain  the  insurance
                  coverage required under  this Agreement; (3) PHYMED's  quality
                  assurance or  utilization  record falls  below  the  standards
                  required under any quality  assurance  or  utilization  review
                  program established by the AMIC or by  any  Health Plan; (4) a
                  bankruptcy  or  insolvency   proceeding  is  initiated  by  or
                  against  PHYMED;  (5) PHYMED  commits a  material breach under

                  under any Managed Care Contract and  the AMIC  determines,  in
                  its sole  judgment,  that such breach impairs  the  ability of

                  Agreement in order to comply with changes required by the duly
                  constituted  regulatory  authorities  of the State of Texas or

this 1st day of September, 1997 by and among Phy.Med., Inc., a Texas corporation
("PHYMED") and The PRS Group, PA., a Texas professional association (PRS), to be
effective as of the 1st day of September, 1997 (the "Effective Date").

                                     RECITAL

         A. PHYMED owns and operates an imaging  center for the  performance  of
radiology  services  located on White  Rock Trail in the City of Dallas,  Dallas
County,  Texas and  anticipates  owning and  operating in the future one or more
additional imaging centers in Dallas and/or Tarrant County, Texas (the Center on
White Rock  Trail and any new,  other or  additional  imaging  centers  owned by
PHYMED and  located in Dallas or Tarrant  County,  Texas  shall be  referred  to
herein collectively as the "Center");

         B. PA is engaged in the  delivery  of  radiology  services  through its
member and  physician  employees  (each a  ARadiologist"  and  collectively  the
"Radiologists"),  each of whom  is a  physician  specializing  in the  field  of
radiology,  qualified  and duly  licensed to  practice  medicine in the State of
Texas;

         C.  PHYMED  desires to enter  into an  agreement  with PA  whereby  PA,
through its member and contracted or employed physicians,  will be the exclusive
provider of radiology services at the Center; and

         D. The  parties  desire to enter  into this  Agreement  in order to set
forth a full statement of their respective duties and responsibilities.

         AGREEMENT

         NOW,  THEREFORE,  for and in  consideration of the mutual covenants and
agreements  contained  herein,  the parties,  each intending to be legally bound
hereby, agree as follows:

1.       ENGAGEMENT OF PA

         1.1  Scope of  Engagement.  PHYMED  hereby  engages  PA,  and PA hereby
agrees, to provide  professional  Radiology Services in the Center in accordance
with the terms of this Agreement. As used in this Agreement, the term "Radiology
Services"  shall include,  but not  necessarily be limited to, the  performance,
reading,  and  interpretation  of x-rays  and  other  radiographic  and  imaging
procedures,  diagnostic  ultrasound,  CT  scanning,  fluoroscopic  examinations,
mammography,  magnetic  resonance  imaging  ("MRI"),  inpatient  and  outpatient
interventional procedures, and nuclear radiologic services.

         1.2 Term of  Agreement.  This  Agreement  shall be  effective as of the
Effective Date, and continue for a term of ten (10) years (the "Primary  Term"),
unless earlier terminated pursuant to the provisions of this Agreement. The term
of this Agreement  shall be extended for additional  five (5) year periods (each
an "Extended  Term"),  whether one or more,  commencing on the expiration of the



                                       79


<PAGE>


Primary Term and on the expiration of each succeeding  Extended Term, unless (i)
at least  six (6)  months  before  the  expiration  of the  Primary  Term or any
Extended Term, as applicable,  either party delivers to the other written notice
of its election not to renew this Agreement, or (ii) either party is in material
default of its  obligations  hereunder.  For the  purposes  of this  Section,  a
material  default by PA or PHYMED  shall not be deemed to exist unless and until
the notice  requirements  set forth in Section 9.1 are satisfied and the time to
cure the default has elapsed  without  PHYMED or PA, as  applicable,  taking the
action  necessary to cure such default.  The provisions of this Section relating
to extension of the term of this Agreement shall not in any way negate the right
of either party to terminate this Agreement in accordance with the provisions of
Section 9 hereof.


2.       RELATIONSHIP OF PARTIES

         2.1 Independent  Contractor Status. In performing its  responsibilities
pursuant  to  this  Agreement,   it  is  understood  and  agreed  that  PA,  any
Radiologists,   and  any  non-physician  employees  of  PA  performing  services
hereunder are at all times acting as independent  contractors of PHYMED. Neither
party is a partner,  joint-venturer,  or  employee  of the other.  PHYMED  shall
neither have nor exercise any control or direction over the medical  judgment of

relate to the diagnosis or treatment of any disease, disorder, defect or injury.

         2.2  Compensation  and Benefits.  Neither PA, its employees  performing

this Agreement is subject to, and agree to comply with, applicable local, state,
and federal  statutes,  rules and  regulations.  Any  provisions  of  applicable
statutes, rules or regulations that invalidate any term of this Agreement,  that
are  inconsistent  with any term of this  Agreement,  or that would cause one or
both of the  parties  hereto to be in  violation  of law shall be deemed to have
superseded  the terms of this  Agreement;  provided,  however,  that the parties
shall  use their  best  efforts  to  accommodate  the  terms and  intent of this
Agreement to the greatest  extent possible  consistent with the  requirements of
applicable  statutes,  rules and  regulations and negotiate in good faith toward

aggregate for the policy year.  Such  insurance  shall not be cancelable  except

notice to be delivered contemporaneously to PHYMED. PA shall furnish or cause to
be furnished to PHYMED  certificates  of insurance  evidencing  the existence of
such  coverage or before the Effective  Date,  and shall during the term hereof,
upon demand, furnish evidence of continuing coverage.

         3.6  Reimbursement.   PA,  as  appropriate,  shall  be  reimbursed  for
reasonable out-of-pocket marketing and other business-related  expenses incurred
on behalf of PHYMED.  The PA agrees to maintain  records and submit  reports for
reimbursement of said expenses following the established  policies of PHYMED for
payment of such  expenses for its own  employees.  PHYMED  reserves the right to
change   and/or   modify  the   reimbursement   policies   for   marketing   and
business-related  expenses from time to time as it deems  appropriate and in the
best interest of the Center.
