Item 6.  Indemnification of Directors and Officers.

         Section 145(a) of the General  Corporation Law of the State of Delaware
("Delaware Corporation Law") provides, in general, that a corporation shall have
the power to indemnify  any person who was or is a party or is  threatened to be
made a party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative(other than an action by
or in the right of the  corporation),  by reason of the fact that he is or was a
director or officer of the  corporation.  Such indemnity may be against expenses
(including  attorneys'  fees),  judgments,  fines and amounts paid in settlement
actually and reasonably  incurred by him in connection with such action, suit or
proceeding,  if the  indemnified  party  acted in good  faith and in a manner he
reasonably  believed  to be in or not  opposed  to  the  best  interests  of the
corporation  and if, with  respect to any  criminal  action or  proceeding,  the
indemnified  party did not have  reasonable  cause to believe  his  conduct  was
unlawful.

         Section 145(b) of the Delaware  Corporation  Law provides,  in general,
that a corporation  shall have the power to indemnify any person who was or is a
party  or is  threatened  to be  made a  party  to any  threatened,  pending  or
completed  action or suit by or in the  right of the  corporation  to  procure a
judgment  in its favor by reason  of the fact  that he is or was a  director  or
officer of the  corporation,  against any expenses  (including  attorneys' fees)
actually  and  reasonably  incurred  by him in  connection  with the  defense or
settlement  of such  action or suit if he acted in good faith and in a manner he
reasonably  believed  to be in or not  opposed  to  the  best  interests  of the
corporation.

         Section 145(g) of the Delaware  Corporation  Law provides,  in general,
that a  corporation  shall have the power to purchase and maintain  insurance on
behalf of any  person who is or was a  director  or  officer of the  corporation
against any liability asserted against him in any such capacity,  or arising out
of his status as such,  whether or not the  corporation  would have the power to
indemnify him against such liability under the provisions of the law.

         Our  Certificate  of  Incorporation  limits the  personal  liability of
directors and officers for monetary  damages to the maximum extent  permitted by
the Delaware  Corporation  Law. Our Certificate of  Incorporation  also provides
that we will  indemnify our directors and officers  against any damages  arising
from their actions as agents of ours,  and that we may  similarly  indemnify our
other  employees and agents.  We are also  empowered  under our  Certificate  of
Incorporation  to enter into  indemnification  agreements with our directors and
officers.

         Our  Bylaws  provide  that,  to the full  extent  permitted  by the our
Certificate of Incorporation and the Delaware Corporation Law, we will indemnify
(and advance  expenses to) our  officers,  directors and employees in connection
with any action,  suit or proceeding  (civil or criminal) to which those persons
are made party by reason of their being a director,  officer or  employee).  Any
such indemnification will be in addition to the advancement of expenses.

         The terms of our Stock  Incentive  Plan  provide  that,  to the fullest
extent  permitted  by our  Certificate  of  Incorporation  and Bylaws and by the
Delaware  Corporation Law, no member of the committee which administers the plan
will be liable for any action or omission  taken with respect to the plan or any
options issued thereunder. The Plans also provide that no member of our Board of
Directors will be liable for any action or determination made in good faith with
respect  to the Plans or any  option  granted  thereunder.  There is no  pending
litigation or proceeding involving any of our directors,  officers, employees or
other agents as to which  indemnification  is being sought,  nor are we aware of
any   pending  or   threatened   litigation   that  may  result  in  claims  for
indemnification by any director, officer, employee or other agent.

Item 7.  Exemption from Registration Claimed.

         Not applicable.

Item 8.  Exhibits.

         The Exhibit Index  immediately  preceding the exhibits is  incorporated
herein by reference.

Item 9.  Undertakings.

         The undersigned registrant hereby undertakes:

          (1)  To file,  during  any  period in which  offers or sales are being
               made, a post-effective amendment to this registration statement:

               (i)  To include any  prospectus  required by Section  10(a)(3) of
                    the Securities Act of 1933;

               (ii) To reflect  in the  prospectus  any facts or events  arising
                    after the effective date of the  registration  statement (or
                    the most recent  post-effective  amendment  thereof)  which,
                    individually  or in the  aggregate,  represent a fundamental
                    change  in the  information  set  forth in the  registration
                    statement;

               (iii)To include  any  material  information  with  respect to the
                    plan  of  distribution  not  previously   disclosed  in  the
                    registration  statement  or  any  material  change  to  such
                    information in the registration statement;

         provided,  however,  that paragraphs (1)(i) and (1)(ii) do not apply if
the  registration  statement  is on Form S-3 or Form  S-8,  and the  information
required to be included in a  post-effective  amendment by those  paragraphs  is
contained in periodic reports filed by the registrant  pursuant to section 13 or
section 15(d) of the Securities  Exchange Act of 1934 that are  incorporated  by
reference in the registration statement.

          (2)  That,  for the purpose of  determining  any  liability  under the
               Securities Act of 1933, each such post-effective  amendment shall
               be  deemed to be a new  registration  statement  relating  to the
               securities  offered therein,  and the offering of such securities
               at that time shall be deemed to be the initial bona fide offering
               thereof.

          (3)  To  remove  from   registration  by  means  of  a  post-effective
               amendment any of the  securities  being  registered  which remain
               unsold at the termination of the offering.

         The  undersigned  registrant  hereby  undertakes  that, for purposes of
determining  any liability  under the Securities Act of 1933, each filing of the
registrant's  annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of any employee benefit
plans annual report pursuant to Section 15(d) of the Securities  Exchange Act of
1934) that is incorporated by reference in the  registration  statement shall be
deemed to be a new  registration  statement  relating to the securities  offered
therein, and the offering of such securities at that time shall be deemed to the
initial bona fide offering thereof.

         Insofar as indemnification for liabilities arising under the Securities
Act may be  permitted to  directors,  officers  and  controlling  persons of the
registrant pursuant to the foregoing  provisions,  or otherwise,  the registrant
has been advised that in the opinion of the Securities  and Exchange  Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore,  unenforceable. In the event that a claim for indemnification
against such  liabilities  (other than the payment by the registrant of expenses
incurred or paid by a director,  officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director,  officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as  expressed  in the  Securities  Act and will be  governed by the final
adjudication of such issue.

Exhibit 4.1

                              STOCK INCENTIVE PLAN

         BSD MEDICAL CORPORATION, a Delaware corporation, (the "Company") adopts
this Stock Incentive Plan (the "Plan"), effective February 9, 1998.

1.  Purpose.  The  purpose of this Plan is to enable the  Company to attract and
retain the  services  of and  provide  performance  incentives  to (1)  selected
employees,  officers and  directors of the Company or of any  subsidiary  of the
Company "Employees") and (2) selected nonemployee agents, consultants,  advisors
and independent contractors of the Company or any subsidiary.

2. Shares  Subject to the Plan.  Subject to adjustment as provided  below and in
paragraph 13, the shares to be offered under the Plan shall consist of shares of
the common stock of the Company,  par value $.01 per share  ("Shares"),  and the
total  number of Shares  that may be issued  under the Plan shall not exceed two
million  (2,000,000) Shares, all of which may be issued pursuant to the exercise
of options granted pursuant to the Plan. The Shares issued under the Plan may be
authorized and unissued  Shares or reacquired  Shares or Shares  acquired in the
market. If any award granted under the Plan expires,  terminates or is canceled,
the unissued  Shares  subject to such award shall again be  available  under the
Plan and if Shares which are awarded under the Plan are forfeited to the Company
or  repurchased  by the Company,  that number of Shares shall again be available
under the Plan.

3.       Effective Date and Duration of Plan.

         (a) Effective  Date.  The Plan (as amended and  restated)  shall become
         effective on the date adopted by the Board of Directors.  Awards may be
         granted  and  Shares  may be awarded or sold under the Plan at any time
         after the effective date and before termination of the Plan.

         (b)  Duration.  The Plan  shall  continue  in effect for a period of 10
         years  from the date  adopted  by the Board of  Directors,  subject  to
         earlier  termination by the Board of Directors.  The Board of Directors
         may suspend or terminate  the Plan at any time,  except with respect to
         awards then outstanding  under the Plan.  Termination  shall not affect
         the terms of any outstanding awards.

4.       Administration.

         (a) Board of Directors.  The Plan shall be administered by the Board of
         Directors of the Company, which shall determine and designate from time
         to time the individuals to whom awards shall be made, the amount of the
         awards and the other terms and conditions of the awards. Subject to the
         provisions  of the Plan,  the Board of Directors  may from time to time
         adopt and amend rules and regulations relating to the administration of
         the Plan,  advance  the lapse of any  waiting  period,  accelerate  any
         exercise  date,  waive or modify any  restriction  applicable to Shares
         (except  those  restrictions   imposed  by  law)  and  make  all  other
         determinations  in the judgment of the Board of Directors  necessary or
         desirable for the  administration of the Plan. The  interpretation  and
         construction  of the  provisions of the Plan and related  agreements by
         the  Board of  Directors  shall be final and  conclusive.  The Board of
         Directors  may correct any defect or supply any  omission or  reconcile
         any inconsistency in the Plan or in any related agreement in the manner
         and to the  extent  it shall  deem  expedient  to carry  the Plan  into
         effect, and it shall be the sole and final judge of such expediency.

         (b)  Committee.  The Board of Directors  may delegate to a committee of
         the Board of  Directors  (the  "Committee")  any or all  authority  for
         administration  of the Plan.  If authority is delegated to a Committee,
         all  references  to the Board of  Directors  in the Plan shall mean and
         relate to the Committee  except (i) as otherwise  provided by the Board
         of  Directors  and (ii) that only the Board of  Directors  may amend or
         terminate the Plan as provided in paragraphs 3 and 14.

         (c) Officer.  The Board of Directors or the  Committee,  as applicable,
         may  delegate  to an  executive  officer of the  Company  authority  to
         administer   those  aspects  of  the  Plan  that  do  not  involve  the
         designation of  individuals  to receive awards or decisions  concerning
         the  timing,  amounts  or other  terms of  awards.  No  officer to whom
         administrative  authority has been delegated pursuant to this provision
         may  waive or modify  any  restriction  applicable  to an award to such
         officer under the Plan.

5. Types of Awards; Eligibility.  The Board of Directors may, from time to time,
take the following  actions,  separately or in combination,  under the Plan: (i)
grant  "Incentive  Stock  Options",  as defined in section  422 of the  Internal
Revenue Code of 1986, as amended (the "Code"),  as provided in paragraph 6; (ii)
grant options other than Incentive Stock Options ("Non-Statutory Stock Options")
as provided in  paragraph 6; (iii) award Shares as provided in paragraph 7; (iv)
sell Shares subject to  restrictions as provided in paragraph 8; (v) grant stock
appreciation  rights as provided in paragraph 9; (vi) grant cash bonus rights as
provided in paragraph  10; (vii) grant  Performance-based  Rights as provided in
paragraph 11 and (viii) grant foreign  qualified awards as provided in paragraph
12.  Any such  awards  may be made to  Employees,  including  Employees  who are
officers or directors,  and to other  individuals  described in paragraph 1 whom
the Board of Directors believes have made or will make an important contribution
to the Company or any subsidiary of the Company;  provided,  however,  that only
Employees  shall be eligible to receive  Incentive Stock Options under the Plan.
The Board of Directors shall select the individuals to whom awards shall be made
and shall  specify the action taken with respect to each  individual  to whom an
award is made.  Unless  otherwise  determined  by the  Board of  Directors  with
respect to an award, each option,  stock appreciation right, cash bonus right or
performance-based  right  granted  pursuant  to the Plan by its  terms  shall be
nonassignable and  nontransferable  by the recipient,  either  voluntarily or by
operation of law,  except by will or by the laws of descent and  distribution of
the state or  country  of the  recipient's  domicile  at the time of  death.  No
fractional  Shares shall be issued in connection  with any award. In lieu of any
fractional  Shares,  cash may be paid in an  amount  equal  to the  value of the
fraction or, if the Board of Directors shall determine, the number of Shares may
be rounded  downward to the next whole share. No Employee may be granted options
or stock  appreciation  rights  under  the Plan for more  than an  aggregate  of
400,000 Shares in any consecutive three-year period.

6. Option  Grants.  With  respect to each option  grant,  the Board of Directors
shall  determine the number of Shares  subject to the option,  the option price,
the period of the option, the time or times at which the option may be exercised
and whether the option is an  Incentive  Stock Option or a  Non-Statutory  Stock
Option and any other  terms of the grant,  all of which shall be set forth in an
option agreement between the Company and the optionee.  In the case of Incentive
Stock Options,  all terms shall be consistent with the  requirements of the Code
and applicable regulations. Upon the exercise of an option, the number of Shares
reserved  for  issuance  under the Plan shall be reduced by the number of Shares
issued  upon  exercise of the option  less the number of Shares  surrendered  or
withheld in connection  with the exercise of the option and the number of Shares
surrendered or withheld to satisfy  withholding  obligations in accordance  with
paragraph 17.

7. Award of Shares.  The Board of  Directors  may award Shares under the Plan as
bonuses or otherwise.  The aggregate number of Shares that may be awarded to any
single  participant  pursuant to this provision shall not exceed 100,000 Shares.
Shares  awarded  pursuant  to this  paragraph  shall be  subject  to the  terms,
conditions,  and restrictions determined by the Board of Directors. The Board of
Directors  may require the  recipient to sign an agreement as a condition of the
award, but may not require the recipient to pay any monetary consideration other
than amounts  necessary to satisfy tax withholding  requirements.  The agreement
may contain  any other  terms,  conditions,  restrictions,  representations  and
warranties required by the Board of Directors. The certificates representing the
Shares awarded shall bear any legends  required by the Board of Directors.  Upon
the  issuance  of a an award of  Shares,  the  number  of Shares  available  for
issuance under the Plan shall be reduced by the number of Shares issued less the
number  of  any  Shares  surrendered  to  satisfy  withholding   obligations  in
accordance with paragraph 17.

8. Purchased Shares.  The Board of Directors may issue Shares under the Plan for
such  consideration  (including  promissory notes and services) as determined by
the Board of  Directors.  Shares  issued  under the Plan shall be subject to the
terms,  conditions and  restrictions  determined by the Board of Directors.  All
Shares  issued  pursuant  to this  paragraph  8 shall be  subject  to a purchase
agreement,  which shall be executed by the Company and the prospective recipient
of the Shares prior to the delivery of certificates  representing such Shares to
the  recipient.  The  purchase  agreement  may  contain  any terms,  conditions,
restrictions, representations and warranties required by the Board of Directors.
The certificates  representing the Shares shall bear any legends required by the
Board of Directors.  Upon the issuance of purchased Shares, the number of Shares
available  for issuance  under the Plan shall be reduced by the number of Shares
issued  less  the  number  of any  Shares  surrendered  to  satisfy  withholding
obligations in accordance with paragraph 17.

9.       Stock Appreciation Rights.

         (a) Grant. Stock  appreciation  rights may be granted under the Plan by
         the Board of Directors, subject to such rules, terms, and conditions as
         the Board of Directors prescribes.

         (b) Exercise.  Each stock  appreciation right shall entitle the holder,
         upon  exercise,  to receive  from the Company in  exchange  therefor an
         amount  equal in value to the  excess of the fair  market  value on the
         date of grant (or, in the case of a stock appreciation right granted in
         connection  with an option,  the excess of the fair market value of one
         Share  over the  option  price per Share  under the option to which the
         stock appreciation  right relates),  multiplied by the number of Shares
         covered  by the stock  appreciation  right or the  option,  or  portion
         thereof, that is surrendered. Payment by the Company upon exercise of a
         stock  appreciation right may be in Shares valued at fair market value,
         in cash,  or partly in Shares and partly in cash,  all as determined by
         the Board of  Directors.  The Board of Directors may withdraw any stock
         appreciation  right  granted  under the Plan at any time and may impose
         any conditions upon the exercise of a stock appreciation right or adopt
         rules and regulations from time to time affecting the rights of holders
         of stock appreciation rights. Such rules and regulations may govern the
         right to exercise stock appreciation  rights granted  thereafter.  Upon
         the exercise of a stock  appreciation  right for Shares,  the number of
         Shares  available  for issuance  under the Plan shall be reduced by the
         number of Shares  issued less the number of any Shares  surrendered  or
         withheld  to  satisfy   withholding   obligations  in  accordance  with
         paragraph  17. Cash  payments for stock  appreciation  rights shall not
         reduce the number of Shares available for issuance under the Plan.

10. Cash Bonus Rights.  The Board of Directors may grant cash bonus rights under
the Plan in  connection  with (i) options  granted or previously  granted,  (ii)
stock appreciation rights granted or previously granted, (iii) Shares awarded or
previously  awarded and (iv) Shares sold or previously sold under the Plan. Cash
bonus  rights  will be subject to rules,  terms and  conditions  as the Board of
Directors may prescribe. The payment of a cash bonus shall not reduce the number
of Shares  available for issuance  under the Plan. A cash bonus right granted in
connection  with an option  will  entitle an  optionee  to a cash bonus when the
related option is exercised (or terminates in connection  with the exercise of a
stock  appreciation  right related to the option) in whole or in part if, in the
sole discretion of the Board of Directors,  the bonus right will result in a tax
deduction  that the Company has  sufficient  taxable income to use. A cash bonus
right granted in connection  with an award of Shares  pursuant to paragraph 7 or
purchase of Shares  pursuant to paragraph 8 will entitle the recipient to a cash
bonus  payable  when the award of Shares is made or the Shares are  purchased or
restrictions,  if any,  to which the Shares  are  subject  lapse.  If the Shares
awarded or purchased  are subject to  restrictions  and are  repurchased  by the
Company or forfeited by the holder,  the cash bonus right  granted in connection
with the Shares awarded or purchased shall terminate and may not be exercised.

11.  Performance-based  Awards. The Board of Directors may grant awards intended
to qualify as  performance-based  compensation  under section 162(m) of the Code
and the regulations thereunder  ("Performance-based Awards").  Performance-based
Awards  shall be  denominated  at the time of grant  either  in  Shares  ("Stock
Performance Awards") or in dollar amounts ("Dollar Performance Awards"). Payment
under a Stock Performance Award or a Dollar  Performance Award shall be made, at
the discretion of the Board of Directors,  subject to the  limitations set forth
in paragraph 2, in Shares ("Performance  Shares"), or in cash or any combination
thereof.  Performance-based  Awards shall be subject to the following  terms and
conditions:

         (a) Award Period.  The Board of Directors shall determine the period of
         time for which a Performance-based Award is made (the "Award Period").

         (b)  Performance  Goals  and  Payment.  The  Board of  Directors  shall
         establish in writing objectives  ("Performance Goals") that must be met
         by the Company or any subsidiary, division or other unit of the Company
         ("Business  Unit")  during the Award  Period as a condition  to payment
         being made under the Performance-based Award. The Performance Goals for
         each award shall be one or more  targeted  levels of  performance  with
         respect to one or more of the following objective measures with respect
         to the Company or any  Business  Unit:  earnings,  earnings  per Share,
         stock price increases,  total shareholder  return (stock price increase
         plus dividends), return on equity, return on assets, return on capital,
         economic value added, revenues,  operating income, cash flows or any of
         the  foregoing  (determined  according to criteria  established  by the
         Board of  Directors).  The Board of Directors  shall also establish the
         number of  Performance  Shares or the amount of cash payment to be made
         under a  Performance-based  Award if the  Performance  Goals are met or
         exceeded,  including  the  fixing  of a  maximum  payment  (subject  to
         paragraph   11(d)).   The  Board  of  Directors  may  establish   other
         restrictions  to payment  under a  Performance-based  Award,  such as a
         continued  employment  requirement,  in addition to satisfaction of the
         Performance  Goals. Some or all of the Performance Shares may be issued
         at the time of the award as restricted  Shares subject to forfeiture in
         whole  or  in  part  if  Performance  Goals,  or if  applicable,  other
         restrictions are not satisfied.

         (c)  Computation  of  Payment.  During  or after an Award  Period,  the
         performance of the Company or Business Unit, as applicable,  during the
         period  shall  be  measured  against  the  Performance  Goals.  If  the
         Performance  Goals  are not  met,  no  payment  shall  be made  under a
         Performance-based  Award. If the Performance Goals are met or exceeded,
         the Board of Directors  shall  certify that fact in writing and certify
         the number of  Performance  Shares earned or the amount of cash payment
         to be made under the terms of the Performance-based Award.

         (d) Maximum Awards. No participant may receive Stock Performance Awards
         in any fiscal year under which the  maximum  number of Shares  issuable
         under the award,  when  aggregated  with the Shares  issuable under any
         awards made in the  immediately  preceding  two fiscal  years,  exceeds
         150,000  Shares or Dollar  Performance  Awards in any fiscal year under
         which  the  maximum  amount  of cash  payable  under  the  award,  when
         aggregated  with the amount of cash  payable  under  awards made in the
         immediately  preceding  two  fiscal  years,  exceeds  an  aggregate  of
         $300,000.

         (e) Effect on Shares  Available.  The  payment  of a  Performance-based
         Award in cash  shall not  reduce  the  number of Shares  available  for
         issuance  under the Plan.  The number of Shares  available for issuance
         under the Plan shall be reduced  by the  number of Shares  issued  upon
         payment of an award, less the number of Shares  surrendered or withheld
         to satisfy withholding obligations.

12.  Foreign  Qualified  Grants.  Awards  under the Plan may be  granted to such
Employees  and such other  persons  described in paragraph 1 residing in foreign
jurisdictions  as the Board of Directors  may determine  from time to time.  The
Board of Directors may adopt such supplements to the Plan as may be necessary to
comply with the  applicable  laws of such  foreign  jurisdictions  and to afford
participants  favorable treatment under such laws;  provided,  however,  that no
award  shall be  granted  under any such  supplement  with  terms  that are more
beneficial to the participants than the terms permitted by the Plan.

13.      Changes in Capital Structure.

         (a) Share Splits and Dividends.  If the number of outstanding Shares of
         the Company is  hereafter  increased  or  decreased  or changed into or
         exchanged  for a different  number or kind of securities of the Company
         by  reason of any Share  split,  combination  or  dividend  payable  in
         Shares,  recapitalization or reclassification,  appropriate  adjustment
         shall  be made by the  Board of  Directors  in the  number  and kind of
         Shares  available for grants under the Plan. In addition,  the Board of
         Directors shall make  appropriate  adjustment in the number and kind of
         Shares  as to which  outstanding  options,  or  portions  thereof  then
         unexercised, shall be exercisable, so that the optionee's proportionate
         interest  before and after the  occurrence of the event is  maintained.
         Notwithstanding  the  foregoing,  the Board of Directors  shall have no
         obligation to effect any  adjustment  that would or might result in the
         issuance of fractional Shares, and any fractional Shares resulting from
         any  adjustment  may be  disregarded  or  provided  for  in any  manner
         determined  by the Board of  Directors.  Any such  adjustments  made by
         Board of Directors shall be conclusive.

         (b) Mergers,  Reorganizations,  Etc. The Board of Directors may include
         such terms and conditions,  including  without  limitation,  provisions
         relating to  acceleration  in the event of a change in  control,  as it
         deems  appropriate  in  connection  with any award  under the Plan with
         respect to a merger,  consolidation,  plan of exchange,  acquisition of
         property or stock,  separation,  reorganization or liquidation to which
         the  Company  or  a  subsidiary  is  a  party  or  a  sale  or  all  or
         substantially  all of the  Company's  assets (each,  a  "Transaction").
         Notwithstanding the foregoing, in the event of a Transaction, the Board
         of Directors  shall,  in its sole discretion and to the extent possible
         under the  structure of the  Transaction,  select one or the  following
         alternatives  for  treating  outstanding  Incentive  Stock  Options  or
         Non-Statutory Stock Options under the Plan:

                  (i)  Outstanding  options shall remain in effect in accordance
                  with their terms; or

                  (ii)  Outstanding  options shall be converted  into options to
                  purchase securities issued by the company that is surviving or
                  acquiring  company in the  Transaction.  The  amount,  type of
                  securities subject thereto and exercise price of the converted
                  options  shall be  determined by the Board of Directors of the
                  Company,  taking  into  account  the  relative  values  of the
                  companies  involved in the  Transaction and the exchange rate,
                  if  any,  used  in  determining  securities  of the  surviving
                  corporation  to be issued to holders of Shares of the Company.
                  Unless  otherwise  determined by the Board of  Directors,  the
                  converted  options shall be vested only to the extent that the
                  vesting  requirements  relating to options  granted  hereunder
                  have been satisfied; or

                  (iii) The Board of  Directors  shall  provide a 30-day  period
                  prior to the  consummation  of the  Transaction  during  which
                  outstanding  options  may  be  exercised  to the  extent  then
                  exercisable,  and upon the  expiration of such 30-day  period,
                  all unexercised options shall immediately terminate. The Board
                  of  Directors  may,  in its sole  discretion,  accelerate  the
                  exercisability of options so that they are exercisable in full
                  during such 30-day period.

         (c) Dissolution of the Company.  In the event of the dissolution of the
         Company,   options  shall  be  treated  in  accordance  with  paragraph
         13(b)(iii).

         (d) Rights  Issued by Another  Corporation.  The Board of Directors may
         also grant options, stock appreciation rights, performance units, stock
         bonuses  and cash  bonuses  and issue  restricted  stock under the Plan
         having terms,  conditions and provisions that vary from those specified
         in this Plan provided that any such awards are granted in  substitution
         for, or in connection with the assumption of, existing  options,  stock
         appreciation rights, stock bonuses, cash bonuses,  restricted stock and
         performance units granted, awarded or issued by another corporation and
         assumed or otherwise  agreed to be provided for by the Company pursuant
         to or by reason of a Transaction.

14.  Amendment of Plan. The Board of Directors may at any time, and from time to
time,  modify  or amend the Plan in such  respects  as it shall  deem  advisable
because  of  changes  in the law  while  the Plan is in  effect or for any other
reason.  Except as provided in paragraphs 9, 10 and 13, however, no change in an
award already granted shall be made without the written consent of the holder of
such award.

15. Approvals.  The obligations of the Company under the Plan are subject to the
approval of state and federal  authorities or agencies with  jurisdiction in the
matter. The Company will use its best efforts to take steps required by state or
federal law or applicable  regulations,  including  rules and regulations of the
Securities and Exchange Commission and any stock exchange on which the Company's
Shares may then be listed,  in  connection  with the grants under the Plan.  The
foregoing  notwithstanding,  the  Company  shall  not be  obligated  to issue or
deliver  Shares  under  the Plan if such  issuance  or  delivery  would  violate
applicable state or federal securities laws.

16. Employment and Service Rights.  Nothing in the Plan or any award pursuant to
the Plan shall (i) confer upon any  Employee  any right to be  continued  in the
employment  of the Company or any  subsidiary  or  interfere in any way with the
right of the  Company or any  subsidiary  by whom such  Employee  is employed to
terminate  such  Employee's  employment  at any time,  for any  reason,  with or
without cause, or to decrease such Employee's  compensation or benefits, or (ii)
confer  upon any  person  engaged by the  Company  any right to be  retained  or
employed  by  the  Company  or  to  the  continuation,  extension,  renewal,  or
modification  of any  compensation,  contract,  or  arrangement  with  or by the
Company.

17. Taxes. Each participant who has received an award under the Plan shall, upon
notification of the amount due, pay to the Company in cash amounts  necessary to
satisfy any applicable federal, state and local withholding requirements. If the
participant  fails to pay the amount  demanded,  the Company may  withhold  that
amount from other amounts  payable by the Company to the  participant  including
salary, subject to applicable law. With the consent of the Board of Directors, a
participant  may satisfy this  withholding  obligation,  in whole or in part, by
having the Company  withhold  from any Shares to be issued that number of Shares
that would  satisfy  the amount due or by  delivering  Shares to the  Company to
satisfy the withholding amount.

18.  Rights as a  Shareholder.  The  recipient of any award under the Plan shall
have no rights as a  shareholder  with  respect to any Shares  until the date of
issue to the  recipient  of a stock  certificate  for  such  Shares.  Except  as
otherwise  expressly  provided  in the  Plan,  no  adjustment  shall be made for
dividends  or other  rights for which the record date  occurs  prior to the date
such stock certificate is issued.

Approved by the Board of Directors: February 9, 1998.

Approved by the Stockholders: August 21, 1998.

subsequent thereto.

SECTION 3.        Administration of the Plan.
----------        --------------------------

         3.1 Stock Option Committee.  Except as is otherwise  expressly provided
herein,  the Plan shall be  administered  by the Committee.  The Committee shall
consist of not less than three (3) members of the Board of Directors  and may be
constituted  by all  members  of the Board of  Directors.  In the event that the
Stock is  registered  under  Section 12 of the Act, the Board of  Directors  may
require that all members of the Committee shall be  "disinterested  persons," as
defined in Rule 16b-3(d)(3) promulgated under the Act; and in such event members
of  the  Committee  shall  not be  eligible  to  receive  stock  options,  stock
appreciation rights, or an allocation of stock under any plan of the Corporation
or its  Affiliates  while they are serving as members of the  Committee and must
not have been eligible to receive  options,  stock  appreciation  rights,  or an
allocation of stock under any plan of the  Corporation or its Affiliates  within
one (1) year prior to their appointment to the Committee.

of the Board of Directors.

         3.3 Meetings and Actions of  Administration  Committee.  The  Committee
shall elect one of its members as its  Chairman  and shall hold its  meetings at
such times and places as it may determine.  All decisions and  determinations of
the  Committee  shall be made by the  majority  vote or  decision  of all of its
members  present  at  a  meeting;  provided,   however,  that  any  decision  or
determination  reduced  to  writing  and  signed  by all of the  members  of the
Committee  shall be as fully  effective as if it had been made at a meeting duly
called  and held.  The  Committee  may make any rules  and  regulations  for the
conduct of its business that are not inconsistent with the provisions hereof and
with the bylaws of the Corporation as it may deem advisable.

         3.4 Committee's  Powers.  Subject to the express provisions hereof, the
Committee shall have the authority, in its sole and absolute discretion,  (a) to
adopt, amend, and rescind  administrative and interpretive rules and regulations
relating  to  the  Plan;  (b) to  determine  the  terms  and  provisions  of the
respective  Agreements  (which  need  not be  identical),  including  provisions
defining or otherwise relating to (i) subject to Section 6 of the Plan, the term
and the period or periods and extent of exercisability of the Options,  (ii) the
extent to which the  transferability  of shares of Stock issued upon exercise of
Options is restricted,  (iii) the effect of  termination of employment  upon the
exercisability of the Options, and (iv) the effect of approved leaves of absence
(consistent with any applicable  regulations of the Internal  Revenue  Service);
(c) subject to Paragraph  6.5, to accelerate the time of  exercisability  of any
Option that has been granted;  (d) to construe the respective  Option Agreements
and the Plan;  and (e) to make all other  determinations  necessary or advisable
for  administering  the Plan. The Committee may correct any defect or supply any
omission or reconcile any  inconsistency  in the Plan or in any Agreement in the
manner and to the extent it shall deem expedient to carry it into effect, and it
shall be the sole and final judge of such expediency.  The determinations of the
Committee on the matters  referred to in this  Paragraph  3.4 shall be final and
conclusive.

SECTION 4.        Eligibility and Participation.
----------        -----------------------------

         4.1  Eligible  Individuals.  Options may be granted  hereunder  only to
persons  who  are  Eligible  Individuals  at  the  time  of the  grant  thereof.
Notwithstanding any provision  contained herein to the contrary,  a person shall
not be  eligible  to  receive  an  Incentive  Option  hereunder  unless he is an
employee of the Corporation or an Affiliates,  nor shall a person be eligible to
receive an Incentive Option hereunder if he, at the time such option is granted,
would own  (within  the  meaning  of  sections  422A and 425 of the Code)  stock
possessing  more than ten percent  (10%) of the total  combined  voting power or
value of all classes of stock of the  Corporation or an Affiliate  unless at the
time such  Incentive  Option is granted the exercise price per share of Stock is
at least one  hundred and ten  percent  (110%) of the Fair Market  Value of each
share of Stock to which the Incentive Option relates and the Incentive Option is
not  exercisable  after the  expiration  of five (5)  years  from the date it is
granted.

         4.2 No Right to Option.  The  adoption of the Plan shall not bee deemed
to give any person a right to be granted an Option.

SECTION 5.        Grant of Options and Certain Terms of the Agreements.
----------        ----------------------------------------------------

                  The Board of Directors  shall  authorize  the initial grant of
Options  under the Plan and with  respect to such  initial  grant shall have all
authority conferred hereunder on the Committee.  In addition,  at all times that
the Plan is in  effect  the  Board of  Directors  may  grant,  but  shall not be
required  to grant,  any  Options  that are  granted  to members of the Board of
Directors,  and with respect to any such grant the Board of Directors shall have
all authority conferred  hereunder on the Committee.  Subject to the immediately
preceding two sentences and the express  provisions  hereof, the Committee shall
determine which Eligible  Individuals  shall be granted  Options  hereunder from
time to time. The Committee shall also determine the number of shares subject to
each of such Options,  and shall  authorize and cause the  Corporation  to grant
Options in accordance with such determinations;  provided, however, that no more
than 20,000 shares of stock may be first made subject to Options in favor of any
member of the Board of  Directors  in any  calendar  year.  Each Option  granted
hereunder  shall be evidenced by an Agreement,  executed by the  Corporation and
the Eligible Individual to whom the Option is granted,  incorporating such terms
as the Committee shall deem necessary or desirable.  More than one Option may be
granted   hereunder  to  the  same  Eligible   Individual   and  be  outstanding
concurrently  hereunder. In the event an Eligible Individual is granted both one
or more  Incentive  Options and one or more  Nonqualified  Options,  such grants
shall be evidenced by separate Agreements,  one for each of the Incentive Option
grants and one for each of the Nonqualified Options grants.

                  Each Agreement may contain or otherwise provide for conditions
giving  rise to the  forfeiture  of the  stock  acquired  pursuant  to an Option
granted hereunder or otherwise and such restrictions on the  transferability  of
shares  of the  Stock  acquired  pursuant  to an  Option  granted  hereunder  or
otherwise as the Committee in its sole and absolute discretion shall deem proper
or advisable.  Such conditions  giving rise to forfeiture may include,  but need
not be limited to, the requirement that the Holder render  substantial  services
to the  Corporation  or its  Affiliates  for a  specified  period of time.  Such
restrictions on transferability may include, but need not be limited to, options
and rights of first refusal in favor of the Corporation and  shareholders of the
Corporation  other  than the Holder of such share of Stock who is a party to the
particular  Agreement or a subsequent holder of the shares of Stock who is bound
by such  Agreement.  Each Agreement  between the Corporation and a member of the
Board of  Directors  shall  provide that twenty  percent  (20%) of the shares of
stock subject to the Option evidenced by the Agreement,  and no more than twenty
percent (20%) of such shares,  shall first become subject to purchase on each of
first  five (5)  anniversaries  of the date of grant of the Option and that each
such twenty percent (20%) increment that becomes first purchasable as of a given
anniversary  date shall  thereafter  remain subject to purchase until the Option
terminates.

SECTION 6.        Terms and Conditions of Options.
----------        -------------------------------

                  All Options granted  hereunder shall comply with, be deemed to
include, and shall be subject to the following terms and conditions:

         6.1 Number of Shares.  Each Agreement  shall state the number of shares
of Stock to which it relates.

         6.2 Exercise  Price.  Each Agreement shall state the exercise price per
share of Stock. The exercise price per share of Stock subject to an Option shall
not be less than the greater of (a) the par value per share of said Stock on the
date of the grant of the Option; provided,  however, that in the case of Options
granted to members of the Board of Directors the exercise  price shall equal the
greater of such amounts  unless  Paragraph 4.1 requires an exercise  price of at
least one hundred and ten percent  (110%) of the Fair Market Value of the shares
of Stock  subject to the Option,  in which case the exercise  price shall be the
greater  of (a) the par value  per  share of said  Stock or (b) 110% of the Fair
Market Value per share of the Stock on the date of grant of the option.

         6.3 Medium, Time of Payment, and Method of Exercise. The exercise price
of an Option  shall be  payable  upon the  exercise  of the  Option in cash,  by
certified or cashier's check, or, with the consent of the Committee, with shares
of Stock of the Corporation owned by the Holder,  including a multiple series of
exchanges of such Stock;  provided,  however, that the exercise price of Options
granted to members of the Board of Directors shall not be payable with shares of
Stock.  Exercise of an Option shall not be effective  until the  Corporation has
received  written  notice of  exercise.  Such notice must  specify the number of
whole  shares to be  purchased  and be  accompanied  by  payment  in full of the
aggregate Option price of the number of shares purchased.  The Corporation shall
not in any case be required to sell,  issue, or deliver a fractional  share with
respect to any Option.

         6.4 Term, Time of Exercise, and Transferability of Options. In addition
to such other terms and conditions as may be included in a particular  Agreement
granting an Option,  an Option shall be exercisable  during a Holder's  lifetime
only by him or by his guardian or legal  representative.  An Option shall not be
transferrable  other than by will or the laws of descent and distribution.  Each
Option shall also be subject to the following terms and conditions:

                   (a)  Termination  of  Employment.   The  provisions  of  this
Paragraph  6.4(a)  shall  apply to the  extent  a  Holder's  Agreement  does not
expressly provide  otherwise.  If a Holder ceases to be employed by at least one
of the employers in the group of employers consistent of the Corporation and its
Affiliates because the Holder voluntarily  terminates employment with such group
of  employers,  the  portion,  if any,  of an Option that  remains  unexercised,
including  that  portion,  if any,  that  pursuant to the  Agreement  is not yet
exercisable,  on the  date  of the  Holder's  termination  of  employment  shall
terminate and cease to be  exercisable as of such date. If a Holder ceases to be
employed by at least one of the  employers in the group of employers  consisting
of the Corporation and its Affiliate because any of such entities terminates the
Holder's  employment for cause,  the portion,  if any, of an Option that remains
unexercised,  including that portion,  if any, that pursuant to the Agreement is
not yet  exercisable,  on the date of the Holder's  termination  of  employment,
shall  terminate  and  cease  to be  exercisable  as of such  date.  A  Holder's
employment shall be deemed  terminated "for cause" if terminated by the Board of
Directors of the  Corporation or the board of directors of an Affiliate  because
of  incompetence,  insubordination,  dishonesty,  other acts  detrimental to the
interest of the  Corporation or its  Affiliates,  or any material  breach by the
Holder of any employment, nondisclosure,  noncompetition, or other contract with
the  Corporation  or  one of its  Affiliates.  Whether  cause  exists  shall  be
determined by such board of directors in its sole  discretion and in good faith.
If a Holder  ceases to be employed by at least one of the employers in the group
of employers  consisting of the  Corporation  and its Affiliates  because one or
more of such entities terminates the employment of the Holder but not for cause,
the Holder shall have the right for ninety (90) days after such  termination  of
employment to exercise the Option with respect to that portion  thereof that has
become exercisable pursuant to Holder's Agreement as of the date of the Holder's
termination of employment.

                   (b) Disability. The provisions of this Paragraph 6.4(b) shall
apply to the extent a Holder's  Agreement does not expressly provide  otherwise.
If a Holder  ceases to be employed by at least one of the employers in the group
of employers  consisting  of the  Corporation  and its  Affiliates  by reason of
disability (as defined in Section  105(d)(4) of the Code), the Holder shall have
the right for six (6) months after the date of  termination  of employment  with
such group of  employers  by reason of  disability  to exercise an Option to the
extent such Option is exercisable on the date of his termination of employment.

                   (c) Death.  The  provisions  of this  Paragraph  6.4(c) shall
apply to the extent a Holder's  Agreement does not expressly provide  otherwise.
If a Holder  dies  while in the employ of the  Corporation  or an  Affiliate  an
Option shall be exercisable by the Holder's legal representatives,  legatees, or
distributees  for six (6) months following the date of the Holder's death to the
extent such Option is exercisable on the Holder's date of death.

              Notwithstanding  any other  provision of this Plan,  including the
provisions of items (a), (b), and (c) of this Paragraph 6.4, no Incentive Option
shall be exercisable  after the expiration of ten (10) years from the date it is
granted, or the period specified in Paragraph 4.01, if applicable. The Committee
shall have  authority to prescribe in any  Agreement  that the Option  evidenced
thereby may be exercised  in full or in part as to any number of shares  subject
thereto at any time or from time to time  during the term of the  Option,  or in
such installments at such times during said term as the Committee may prescribe.
Except as provided  above and unless  otherwise  provided in any  Agreement,  an
Option may be  exercised at any time or from time to time during the term of the
Option.  Such exercise may be as to any or all whole (but no fractional)  shares
which have become purchasable under the Option.

              Within a  reasonable  time or such time as may be permitted by law
after the  Corporation  receives a written notice that the Holder has elected to
exercise all or a portion of an Option, such notice to be accompanied by payment
in full of the  aggregate  Option price of the number of shares  purchased,  the
Corporation  shall  issue and  deliver a  certificate  representing  the  shares
acquired  in  consequence  of the  exercise  and any other  amounts  payable  in
consequence  of such  exercise.  In the event  that a Holder  exercises  both an
Incentive  Option,  or portion thereof,  and a Nonqualified  Stock Option,  or a
portion thereof,  separate Stock certificates shall be issued, one for the Stock
subject  to  the  Incentive  Option  and  one  for  the  Stock  subject  to  the
Nonqualified Stock Option.  The number of the shares of Stock  transferrable due
to an exercise of an Option  under this Plan shall not be  increased  due to the
passage of time, except as may be provided in an Agreement.

              Nothing  herein or in any Option granted  hereunder  shall require
the Corporation to issue any shares upon exercise of any Option if such issuance
would, in the opinion of counsel for the Corporation,  constitute a violation of
the Securities Act of 1933, as amended, or any similar or superseding statute or
statutes,  or any other applicable statute or regulation,  as then in effect. At
the time of any  exercise  of an Option,  the  Corporation  may,  as a condition
precedent to the exercise of such Option,  require from the Holder of the Option
(or  in  the  event  of his  death,  his  legal  representatives,  legatees,  or
distributees) such written  representations,  if any,  concerning his intentions
with regard to the  retention or  disposition  of the shares  being  acquired by
exercise of such Option and such written covenants and agreements, if any, as to
the  manner of  disposal  of such  shares  as, in the  opinion of counsel to the
Corporation,  may be necessary to ensure that any disposition by such Holder (or
in  the  event  of  his  death,   his  legal   representatives,   legatees,   or
distributees),  will not involve a violation of the  Securities  Act of 1933, as
amended,  or any  similar  or  superseding  statute  or  statutes,  or any other
applicable  state  or  federal  statute  or  regulation,   as  then  in  effect.
Certificates for shares of Stock, when issued, may have the following legend, or
statements of other applicable  restrictions,  endorsed thereon,  and may not be
immediately transferable:

                  The shares of Stock  evidenced by this  certificate  have been
                  issued  to the  registered  owner  in  reliance  upon  written
                  representations  that these  shares  have been  purchased  for
                  investment.  These  shares  may not be sold,  transferred,  or
                  assigned  unless,  in the opinion of the  Corporation  and its
                  legal counsel,  such sale, transfer, or assignment will not be
                  in  violation  of the  Securities  Act of  1933,  as  amended,
                  applicable   rules  and  regulations  of  the  Securities  and
                  Exchange Commission, and any applicable state securities law.

         6.5  Limitation  on  Aggregate  Value of Shares  That May Become  First
Exercisable During Any Calendar Year Under an Incentive Option.  With respect to
any Incentive Option granted under this Plan, the aggregate Fair Market Value of
shares of Stock subject to such  Incentive  Option and the aggregate Fair Market
Value of  shares of Stock or stock of any  Affiliate  (or a  predecessor  of the
Corporation or an Affiliate) subject to any other incentive stock option (within
the meaning of section 422A of the Code) of the  Corporation  or its  Affiliates
(or a  predecessor  corporation  of any such  corporation),  that  first  become
purchasable in any calendar year under such Option, may not (with respect to any
Holder) exceed $100,000,  with such Fair Market Value to be determined as of the
date the  Incentive  Option is  granted.  For  purposes of this  Paragraph  6.5,
"predecessor  corporation" means a corporation that was a party to a transaction
described  in section  425(a) of the Code (or which would be so  described  if a
substitution  or  assumption  under such  section  had been  effected)  with the
Corporation,  or a corporation which, at the time the new incentive stock option
(within the meaning of section 422A of the Code) is granted,  is an Affiliate of
the  Corporation  or a predecessor  corporation of any such  corporations,  or a
predecessor corporation of any such corporations.

         6.6 Adjustments  Upon Changes in  Capitalization.  Notwithstanding  any
other provisions hereof, in the event of any change in the number of outstanding
shares of Stock  effected  without  receipt  of  consideration  therefor  by the
Corporation,  by reason of a stock dividend, or split, combination,  exchange of
shares or other recapitalization, merger, or otherwise, in which the Corporation
is the surviving  corporation,  the  aggregate  number and class of the reserved
shares,  the number and class of shares subject to each  outstanding  Option and
the Option price of each outstanding  Option shall be automatically  adjusted to
accurately  and equitably  reflect the effect  thereon of such change,  provided
that any fractional  share resulting from such adjustment may be eliminated.  In
the event of a dispute concerning such adjustment, the decision of the Committee
shall be  conclusive.  The  number of  reserved  shares or the  number of shares
subject to any outstanding Option shall be automatically reduced by any fraction
included  therein  which  results  from any  adjustment  made  pursuant  to this
Paragraph 6.6. A dissolution or liquidation of the Corporation,  a merger (other
than a merger effecting a  reincorporation  of the Corporation in another state)
or consolidation in which the Corporation is not the surviving corporation, or a
transaction in which another corporation becomes the owner of 50% or more of the
total  combined  voting power of all classes of stock of the  Corporation  shall
cause every Option then  outstanding  to terminate,  but the Holder of each such
then outstanding  Options shall, in any event,  subject to the limitation on the
number of shares that may become first exercisable  during any calendar year set
forth in Paragraph 6.5, have the right,  immediately  prior to such dissolution,
liquidation, merger, consolidation, or transaction, to exercise such Options, to
the extent not theretofore exercised,  without regard to the determination as to
the periods and installments of  exercisability  made pursuant to Paragraph 6.12
if (and only if) such Options have not at that time expired or been  terminated.
Such  acceleration  of  exercisability  shall not apply to a given Option if any
surviving or acquiring  corporation  agrees to assume such Option in  connection
with the merger, consolidation, or transaction.

         6.7  Rights  as a  Shareholder.  A  Holder  shall  have no  right  as a
shareholder with respect to any shares covered by his Option until a certificate
representing  such  shares  is issued to him.  No  adjustment  shall be made for
dividends  (ordinary  or  extraordinary,  whether in cash or other  property) or
distributions  or other  rights for which the  record  date is prior to the date
such certificate is issued, except as provided in Paragraph 6.6 hereof.

         6.8 Modification,  Extension and Renewal of the Options. Subject to the
terms and  conditions of and within the  limitations  of the Plan, the Committee
may modify,  extend or renew  outstanding  Options  granted  under the Plan,  or
accept  the  surrender  of  Options  outstanding  hereunder  (to the  extent not
theretofore  exercised)  and  authorize  the  granting of new opts  hereunder in
substitution therefor (to the extent not theretofore  exercised).  The Committee
may not,  however,  without the consent of the  Holder,  modify any  outstanding
Options so as to  specify a lower  exercise  price or Base  Amount or accept the
surrender of  outstanding  Incentive  Options and  authorize the granting of new
Options in substitution  therefor  specifying a lower option price. In addition,
no modification of an Option granted hereunder shall, without the consent of the
Holder,  alter or impair any rights or obligations under any Option  theretofore
granted  hereunder  to such Holder under the Plan,  except as may be  necessary,
with respect to Incentive  Options,  to satisfy the requirements of section 422A
of the Code.

         6.9 Furnish  Information.  Each Holder shall furnish to the Corporation
all  information  requested by the  Corporation  to enable it to comply with any
reporting  or other  requirement  imposed upon the  Corporation  by or under any
applicable statute or regulation.

         6.10 Obligation to Exercise; Termination of Employment. The granting of
an Option  hereunder  shall impose no obligation upon the Holder to exercise the
same or any part thereof.  In the event of a Holder's  termination of employment
with the  Corporation  or an  Affiliate,  the  unexercised  portion of an Option
granted hereunder shall terminate in accordance with Paragraph 6.4 hereof.

         6.11  Redemption.  At such time that the Stock is not registered  under
section 12 of the  Securities  Exchange  Act, if a Holder or any other holder of
Stock received upon exercise of an Option granted  hereunder,  proposes to sell,
give,  pledge,  exchange  or  otherwise  transfer or dispose of any of the Stock
received  upon  the  exercise  of an  Option  granted  under  the Plan or of any
interests  therein owned by him,  whether for cash or other  consideration,  the
Holder or such other holder shall promptly give notice (the "Redemption Notice")
to the Committee  setting forth in detail the  circumstances  of such event. The
Redemption  Notice shall state the name and address of the  proposed  transferee
and the proposed  consideration  for and terms of the transfer.  The Corporation
shall have an option to purchase  such Stock within ten (10) days after  receipt
by the Committee of the Redemption  Notice,  on the terms  hereinafter set forth

gift, or

                   (b) the price per share for which the Holder  has  received a

discontinue the Plan or revise or amend it in any respect whatsoever;  provided,
however,  that,  without  the  approval  of the  holders  of a  majority  of the

-----------       -------

Corporation guarantees the Stock of the Corporation from loss or depreciation.

never been included herein.

Exhibit 5.1 / Opinion of Counsel

                               OPINION OF COUNSEL

BSD Medical Corp.
2188 South 2200 South
West Valley, Utah  84119

     Re:  BSD Medical Corp.  Registration  Statement on Form S-8, filed November
          22, 2000

Gentlemen:

         We have acted as counsel to BSD Medical Corp.,  a Delaware  corporation
(the  "Company"),  in connection  with the  preparation of the  above-referenced
Registration Statement on Form S-8 (the "Registration Statement"),  filed by the
Company  with the  Securities  and Exchange  Commission  (the  "Commission")  on
November 22, 2000. The Registration  Statement relates to the registration under
the Securities Act of 1933, as amended (the "Act"), of up to 1,800,000 shares of
common stock (the "Shares"),  par value $.01 per share, to be issued and sold by
the Company  pursuant to the 1987 Stock Option Plan and the 1998 Stock Incentive
Plan of the Company.

         This opinion is delivered in accordance  with the  requirements of Item
601(b)(5) of Regulation S-K promulgated under the Act.

         In connection with this opinion,  we have examined originals or copies,
certified or otherwise identified to our satisfaction, of (i) the Certificate of
Incorporation of the Company; (ii) the Bylaws of the Company as amended to date;
(iii) certain  resolutions and written consents of the Board of Directors of the
Company relating to the offering of the Shares; (iv) the Registration Statement,
and (v) such other  documents as we have deemed  necessary or appropriate as the
basis for the opinions set forth below. In such examination, we have assumed the
authenticity  of all  signatures,  the legal  capacity of natural  persons,  the
authenticity  of all documents  submitted to us as originals,  the conformity to
original documents of all documents  submitted to us as certified or photostatic
copies and the authenticity of the originals of such latter documents. As to any
facts  material to this  opinion  which we did not  independently  establish  or
verify, we have relied upon statements and representations of officers and other
representatives of the Company and others.

         Members of our firm are admitted to the practice of law in the State of
Utah, and we express no opinion as to the laws of any other jurisdiction.

         Based upon and subject to the  foregoing,  we are of the  opinion  that
when (i) the Registration  Statement  becomes  effective,  and (ii) certificates
representing  the  Shares  are  duly  executed,  countersigned,  registered  and
delivered  upon payment of the agreed upon  consideration  therefor,  the Shares
will be duly authorized, validly issued, fully paid and non-assessable.

         We hereby  consent to the  filing of this  opinion as an exhibit to the
Registration  Statement and to the use of our name in the  Prospectus  contained
therein.  In giving  such  consent  we do not  thereby  admit that we are in the
category of persons whose consent is required under Section 7 of the Act.

                                             Very truly yours,

                                             /s/ Parsons Behle & Latimer
