ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 .
         The Certificate of  Incorporation  of the Registrant  provides that the
Registrant shall, to the fullest extent permitted by law,  indemnify any and all
officers  and  directors  of the  Registrant,  and may,  to the  fullest  extent
permitted by law or to such lesser extent as is determined in the  discretion of
the Board of Directors of the Registrant,  indemnify and advance expenses to any
and all  other  persons  whom it shall  have the  power to  indemnify,  from and
against all expenses,  liabilities or other matters  arising out of their status
as such or their acts, omissions or services rendered in such capacities.

         The Registrant's  Certificate of Incorporation  limits the liability of
directors,  providing  that no director of the  Registrant  shall be  personally
liable to the Registrant or its  stockholders for monetary damages for breach of
fiduciary  duty as a director,  except for such  liability as is  expressly  not
subject to limitation under the Delaware General  Corporation  Laws, as the same
exists or may hereafter be amended to further limit or eliminate such liability.

         The  Certificate of  Incorporation  of the Registrant also provides the
Registrant the power to purchase and maintain  insurance on behalf of any person
who is or was a director, officer, employee or agent of the Registrant, or is or
was serving at the request of the Registrant as a director, officer, employee or
agent  of  another  corporation,  partnership,  joint  venture,  trust  or other
enterprise,  against any liability  asserted  against him and incurred by him in
any such  capacity,  or arising  out of his  status as such,  whether or not the
Registrant would have the power to indemnify him against such liability.

         The Registrant's  Certificate of  Incorporation  also provides that, in
addition to the other powers and authority conferred upon the Board of Directors
by statute or by its  Certificate  of  Incorporation,  the Board of Directors is
empowered to exercise all such powers and do all such things as may be exercised
or done by the  Registrant,  subject to the  provisions of the Delaware  General
Corporation  Laws, the Registrant's  Certificate of Incorporation and the Bylaws
adopted by the stockholders;  provided,  however,  that no Bylaws adopted by the
stockholders shall invalidate any prior act of the Board of Directors that would
have been valid if such Bylaws had not been adopted.

         The Registrant's Bylaws provide for indemnification as follows:

                                   "ARTICLE 7
                          INDEMNIFICATION OF DIRECTORS,
                         OFFICERS, EMPLOYEES AND AGENTS

         Section 7.1.  Third-Party  Actions. The corporation shall 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 such  person is or was a
director or officer of the  corporation,  or is or was serving at the request of
the  corporation as a director or officer of another  corporation,  partnership,
joint  venture,  trust or other  enterprise,  against  all  expenses  (including
attorney's fees),  judgments,  fines and amounts paid in settlement actually and
reasonably  incurred  by such person in  connection  with such  action,  suit or
proceeding  if such  person  acted in good  faith  and in a manner  such  person
reasonably  believed  to be in or not  opposed  to  the  best  interests  of the
corporation,  and,  with respect to any criminal  action or  proceeding,  had no
reasonable cause to believe his or her conduct was unlawful.  The termination of
any action, suit or proceeding by judgment,  order, settlement,  conviction,  or
upon a plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which such
person reasonably  believed to be in or not opposed to the best interests of the
corporation,  and, with respect to any criminal action or proceeding,  that such
person had reasonable cause to believe that his or her conduct was unlawful.

         The corporation may indemnify any employee or agent of the corporation,
or any  employee  or agent  serving  at the  request  of the  corporation  as an
employee or agent of another corporation,  partnership,  joint venture, trust or
other  enterprise,  in the manner and to the extent that it shall  indemnify any
director or officer under this Section 7.1.

         Section 7.2.  Derivative  Actions.  The corporation shall 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 such
person is or was a director,  officer, employee or agent of the corporation,  or
is or was serving at the  request of the  corporation  as a  director,  officer,
employee or agent of another corporation,  partnership,  joint venture, trust or
other enterprise,  against all expenses (including attorneys' fees) actually and
reasonably  incurred by such person in connection with the defense or settlement
of such action or suit if such  person  acted in good faith and in a manner such
person reasonably  believed to be in or not opposed to the best interests of the
corporation,  except that no  indemnification  shall be made with respect to any
claim,  issue or matter as to which such person  shall have been  adjudged to be
liable for negligence or misconduct in the  performance of such person's duty to
the  corporation  unless and only to the extent  that the Court of  Chancery  of
Delaware or the court in which such action or suit was brought  shall  determine
upon application that,  despite the adjudication of liability but in view of all
the circumstances of the case, such person is fairly and reasonably  entitled to
indemnity  for such  expenses  which the Court of  Chancery  of Delaware or such
other court shall deem proper.

         Section 7.3.  Determination  of  Indemnification.  Any  indemnification
under Section 7.1 or 7.2 of this Article 7 (unless  ordered by a court) shall be
made  by the  corporation  only  as  authorized  in  the  specific  case  upon a
determination that indemnification of the director,  officer,  employee or agent
is  proper in the  circumstances  because  such  person  has met the  applicable
standard  of  conduct  set forth in Section  7.1 or 7.2 of this  Article 7. Such
determination  shall be made (i) by a majority vote of the directors who are not
parties to such action,  suit or proceeding,  even though less than a quorum, or
(ii) if  there  are no  such  directors,  or if such  directors  so  direct,  by
independent legal counsel in a written opinion, or (iii) by the stockholders.

         Section  7.4.  Right  to  Indemnification.  Notwithstanding  the  other
provisions of this Article 7, to the extent that a director,  officer,  employee
or agent of the  Corporation  has been  successful on the merits or otherwise in
defense of any action,  suit or proceeding  referred to in Section 7.1 or 7.2 of
this Article 7, or in defense of any claim, issue or matter therein, such person
shall be indemnified against expenses  (including  attorneys' fees) actually and
reasonably incurred by such person in connection therewith.

         Section  7.5.  Advance of  Expenses.  Expenses  incurred in defending a
civil or criminal  action,  suit or proceeding may be paid by the corporation on
behalf  of a  director,  officer,  employee  or agent in  advance  of the  final
disposition  of such action,  suit or  proceeding  as authorized by the board of
directors in the specific case upon receipt of an undertaking by or on behalf of
the director, officer, employee or agent to repay such amount unless it shall


                                      II-3

<PAGE>



ultimately be determined  that such person is entitled to be  indemnified by the
corporation as authorized in this Article 7.

         Section  7.6.   Indemnification  Not  Exclusive.   The  indemnification
provided by this Article 7 shall not be deemed  exclusive of any other rights to
which  any  person  seeking  indemnification  may be  entitled  under  any  law,
agreement, vote of stockholders or disinterested directors or otherwise, both as
to action  in such  person's  official  capacity  and as to  action  in  another
capacity  while holding such office,  and shall  continue as to a person who has
ceased to be a  director,  officer,  employee  or agent  and shall  inure to the
benefit of the heirs, executors and administrators of such a person.

         Section  7.7.  Insurance.  The  corporation  may  purchase and maintain
insurance on behalf of any person who is or was a director, officer, employee or
agent of the corporation, or is or was serving at the request of the corporation
as a director,  officer, employee or agent of another corporation,  partnership,
joint venture,  trust or other enterprise against any liability asserted against
such person and incurred by such person in any such capacity,  or arising out of
such  person's  status as such,  whether or not the  corporation  would have the
power to indemnify  such person against  liability  under the provisions of this
Article 7.

         Section 7.8. Definitions of Certain Terms. For purposes of this Article
7, references to "the corporation"  shall include,  in addition to the resulting
corporation,  any  constituent  corporation  (including  any  constituent  of  a
constituent)  absorbed  in a  consolidation  or merger  which,  if its  separate
existence  had  continued,  would have had power and  authority to indemnify its
directors,  officers,  employees  or agents,  so that any person who is or was a
director,  officer, employee or agent of such constituent corporation,  or is or
was  serving  at the  request of such  constituent  corporation  as a  director,
officer, employee or agent of another corporation,  partnership,  joint venture,
trust or other enterprise, shall stand in the same position under the provisions
of this Article 7 with respect to the resulting or surviving corporation as such
person would have with respect to such  constituent  corporation if its separate
existence had continued.

         For purposes of this Article 7, references to "other enterprises" shall
include employee  benefit plans;  references to "fines" shall include any excise
taxes assessed on a person with respect to an employee benefit plan;  references
to "serving at the request of the  corporation"  shall  include any service as a
director, officer, employee or agent of the corporation which imposes duties on,
or involves services by such director,  officer,  employee or agent with respect
to an employee benefit plan, its participants,  or  beneficiaries;  and a person
who acted in good faith and in a manner such person reasonably believed to be in
the interest of the participants  and  beneficiaries of an employee benefit plan
shall be deemed to have acted in a manner "not opposed to the best  interests of
the corporation" as referred to in this Article 7.

         Section 7.9. Liability of Directors.  Notwithstanding  any provision of
the  Certificate of  Incorporation  or any other provision  herein,  no director
shall be personally  liable to the  Corporation or any  stockholder for monetary
damages for breach of  fiduciary  duty as a  director,  except for any matter in
respect of which such  director  shall be liable under Section 174 of Title 8 of
the Delaware  Code  (relating to the Delaware  General  Corporation  Law) or any
amendment  thereto or successor  provision  thereto or shall be liable by reason
that, in addition to any and all other  requirements for such liability,  he (i)
shall have breached his duty of loyalty to the Corporation or its  stockholders,
(ii)  shall not have  acted in good  faith,  (iii)  shall have acted in a manner
involving intentional misconduct or a knowing violation of law or, in failing to
act, shall have acted in a manner involving intentional  misconduct or a knowing
violation of law or (iv) shall have derived an improper personal benefit."

         Pursuant  to the  provisions  of Section  145 of the  Delaware  General
Corporation  Law,  every  Delaware  corporation  has 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  (other than an
action by or in the right of the  corporation)  by reason of the fact that he or
she is or  was a  director,  officer,  employee  or  agent  of any  corporation,
partnership,  joint  venture,  trust or other  enterprise,  against  any and all
expenses,  judgments,  fines  and  amounts  paid in  settlement  and  reasonably
incurred in  connection  with such  action,  suit or  proceedings.  The power to
indemnify  applies only if such person acted in good faith and in a manner he or
she reasonably  believed to be in the best interest,  or not opposed to the best
interest,  of the  corporation  and  with  respect  to any  criminal  action  or
proceeding, had no reasonable cause to believe his or her conduct was unlawful.


                                      II-4

<PAGE>



         The power to indemnify applies to actions brought by or in the right of
the  corporation  as well,  but only to the  extent of  defense  and  settlement
expenses and not to any  satisfaction  of a judgment or  settlement of the claim
itself,  and with the further limitation that in such actions no indemnification
shall  be made  in the  event  of any  adjudication  unless  the  court,  in its
discretion,  believes that in the light of all the circumstances indemnification
should apply.

         To the extent any of the  persons  referred  to in the two  immediately
preceding  paragraphs is  successful  in the defense of the actions  referred to
therein, such person is entitled, pursuant to Section 145, to indemnification as
described above.

         (a) 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 (a)(1)(i) and (a)(1)(ii)
do not apply if 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 1934 Act 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.

         (b) 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 Section 15(d) of the
1934 Act (and,  where  applicable,  each  filing of an employee  benefit  plan's
annual report pursuant to Section 15(d) of the 1934 Act) 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 be the  initial  bona fide  offering
thereof.

         (c)  Insofar  as  indemnification  for  liabilities  arising  under the
Securities Act of 1933 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 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 Act and will
be governed by the final adjudication of such issue.

Mr. L.C. Arnold

Dear Mr. Arnold

You  currently  have an option (the  "Option")  to purchase  50,000  shares (the
"Shares") in Authoriszor Inc. (the "Company") at a price of $1.00 at any time up
to 1st January 2001.

The Company is negotiating to place shares to raise $10 - $15 million,  but this
is likely to take some time to  complete.  It would be in the best  interests of
the  Company  to have  some  working  capital  now;  accordingly  the  Board has
authorized me to approach  certain  warrant and option holders to invite them to
subscribe for their  entitlement to shares of Company common stock at a discount
of one-third to the issue price provided that such options are exercised in full
no later than the later of 31st January 2000 or five (5) business days after the
filing of the  Registration  Statement (as hereinafter  defined).  In your case,
this would mean  subscribing  for 50,000  Shares at an  exercise  price of 66.66
cents per share instead of $1.00.

The  Company  contemplates  filing  a  Form  S-8  registration   statement  (the
"Registration  Statement")  covering,  inter alia,  the  issuance of the Shares.
Promptly after the filing of the Registration  Statement,  the Company will send
you an Executive  Summary  relating,  inter alia, to the Stock Option  Agreement
with respect to the Option.  The Executive  Summary serves as a Prospectus under
the Registration Statement. You are urged not to exercise the Option until after
you have received the Executive Summary and had an opportunity to carefully read
the Executive Summary.

If you desire to exercise your Option at the reduced  exercise price pursuant to
the terms set forth  herein,  please sign the  enclosed  copy of this letter and
effect a telegraphic  transfer for $33,334 to the Company's  account at Comerica
Bank, 1300 North Park Center,  Dallas,  Texas  75265-0282;  ABA No.:  111000753;
Account Name: Toucan Gold Corporation;  Account No: 1880416886;  in full payment
for the issue of 50,000 shares of Company common stock.

Yours sincerely,

                           (i) This Option may not be  exercised if the issuance

                  respect to such Shares.

         Section  3. Term of Option.  This  Option  may not be  exercised  after
January 1, 2001 and is subject to earlier  termination as provided in Section 4.

                  results   from  the   participation   of  the   Company  in  a
                  reorganization,  consolidation,  merger,  liquidation  or  any

                           (iii)  Neither  (i) nor  (ii) of  this  Section  4(b)
                  shall,    directly    or    indirectly,    include    (x)    a

         stock  split-up,  combination  or exchange of shares,  then and in such
         event appropriate  adjustment shall be made in the number of Shares and
         the exercise  price per Share  thereof then subject to this Option,  so
         that the same proportion of the Company's issued and outstanding shares
         shall remain subject to purchase at the same aggregate exercise price.

                  (c) Without  limiting the  generality  of the  foregoing,  the

         expediency.  The  Company  shall  have  full  discretion  to  make  all
         determinations  on the matters  referred to in this Section  8(b),  and
         such determinations shall be final, binding and conclusive.

         Section 9.  Government  Regulations.  The granting and exercise of this
Option and the  obligation of the Company to sell and deliver  Shares under this

this Option Agreement,  such notice must be in writing and personally  delivered
or sent by mail or delivery by a  nationally  recognized  courier  service.  Any
notice required or permitted to be delivered  under this Option  Agreement shall
be deemed to be delivered on the date on which it is personally  delivered,  or,

         position with or relationship to the Company or its subsidiaries.  This
         Option  shall not confer upon the  Optionee the right to continue as an
         employee,  consultant  or  advisor,  or  interfere  in any way with the
         rights  of  the  Company  to  terminate  the  Optionee's  status  as an
         employee, consultant or advisor.

                  (b) The  members of the Board shall not be liable for any act,

         this Option,  and members of the Board shall,  in addition to all other
         rights  of   indemnification   and   reimbursement,   be   entitled  to
         indemnification  and  reimbursement  by the  Company  in respect of any
         claim, loss, damage,  liability or expense (including  attorneys' fees,

         independent legal counsel selected by the Company,  and amounts paid in
         satisfaction of a judgment, except a judgment based on a finding of bad
         faith) arising from such claim, loss,  damage,  liability or expense to

         accordance  with the  provisions of this Option,  shall,  to the extent
         thereof,  be in full  satisfaction  of all claims of such persons under
         this  Option.  The  Company  may  require  the  Optionee,  or any legal
         representative,  heir, legatee or distributee as a condition  precedent
         to such payment or issuance or transfer of Shares, to execute a release
         and receipt for such  payment or issuance or transfer of Shares in such

         Company may  recover  any and all  damages,  fees,  expenses  and costs
         arising out of any  actions  taken by the Company to enforce its rights
         under this Option.

                  (h) If any  provision  of this Option is held to be illegal or
         invalid for any reason,  the illegality or invalidity  shall not affect
         the remaining  provisions of this Option,  but such provision  shall be
         fully severable,  and this Option shall be construed and enforced as if
         the  illegal  or invalid  provision  had never  been  included  in this
         Option.

Dear Mr. Jeffcock

You  currently  have an option (the  "Option") to purchase  200,000  shares (the
"Shares") in Authoriszor Inc. (the "Company") at a price of $1.00 at any time up
to 1st January 2001.

The Company is negotiating to place shares to raise $10 - $15 million,  but this
is likely to take some time to  complete.  It would be in the best  interests of
the  Company  to have  some  working  capital  now;  accordingly  the  Board has
authorized me to approach  certain  warrant and option holders to invite them to
subscribe for their  entitlement to shares of Company common stock at a discount
of one-third to the issue price provided that such options are exercised in full
no later than the later of 31st January 2000 or five (5) business days after the
filing of the  Registration  Statement (as hereinafter  defined).  In your case,
this would mean  subscribing  for 200,000  Shares at an exercise  price of 66.66
cents per share instead of $1.00.

The  Company  contemplates  filing  a  Form  S-8  registration   statement  (the
"Registration  Statement")  covering,  inter alia,  the  issuance of the Shares.
Promptly after the filing of the Registration  Statement,  the Company will send
you an Executive  Summary  relating,  inter alia, to the Stock Option  Agreement
with respect to the Option.  The Executive  Summary serves as a Prospectus under
the Registration Statement. You are urged not to exercise the Option until after
you have received the Executive Summary and had an opportunity to carefully read
the Executive Summary.

If you desire to exercise your Option at the reduced  exercise price pursuant to
the terms set forth  herein,  please sign the  enclosed  copy of this letter and
effect a telegraphic  transfer for $133,336 to the Company's account at Comerica
Bank, 1300 North Park Center,  Dallas,  Texas  75265-0282;  ABA No.:  111000753;
Account Name: Toucan Gold Corporation;  Account No: 1880416886;  in full payment
for the issue of 200,000 shares of Company common stock.

Yours sincerely,


/s/ R.P. Jeffcock

You  currently  have an option (the  "Option")  to purchase  50,000  shares (the
"Shares") in Authoriszor Inc. (the "Company") at a price of $1.00 at any time up
to 1st January 2001.

no later than the later of 31st January 2000 or five (5) business days after the
filing of the  Registration  Statement (as hereinafter  defined).  In your case,
this would mean  subscribing  for 50,000  Shares at an  exercise  price of 66.66
cents per share instead of $1.00.

The  Company  contemplates  filing  a  Form  S-8  registration   statement  (the

Promptly after the filing of the Registration  Statement,  the Company will send

                  (c)      Restrictions on Exercise.

                           (i) This Option may not be  exercised if the issuance
                  of the Shares upon such exercise would  constitute a violation
                  of any applicable  federal or state securities or other law or
                  valid  regulation.  As a  condition  to the  exercise  of this
                  Option,  the Company may require the exercising person to make
                  any  agreements and  undertakings  that may be required by any
                  applicable law or regulation.

                  of  1933,   as  amended  (the  "Act"),   shall  be  restricted
                  securities subject to the terms of Rule 144 under the Act. The
                  certificates  representing  any  such  Shares  shall  bear  an
                  appropriate legend restricting transfer and the transfer agent
                  of the Company shall be given stop transfer  instructions with
                  respect to such Shares.

         Section 3. Term of Option. This Option may not be exercised after April
1, 2002 and is subject  to  earlier  termination  as  provided  in Section 4. In
addition,  this  Option  is  subject  to  cancellation  by  the  Company  upon a
significant  corporate event as provided in Section 4 below.  This Option may be
exercised  during  such times only in  accordance  with the terms of this Option
Agreement.

                  (a) The Company in its sole  discretion may, by giving written

         the  transactions  described in Section  4(a)(i) or  4(a)(ii),  cancel,
         effective   upon  the  date  of  the   consummation   of  any  of  such
         transactions,   all  or  any  portion  of  this  Option  that   remains
         unexercised  on such date.  Such  Cancellation  Notice shall be given a
         reasonable  period  of time  (but not less  than 15 days)  prior to the
         effective date of such cancellation,  and may be given either before or
         after stockholder approval of such transaction.

                           (i) Any transaction  (which shall include a series of
                  transactions occurring within 60 days or occurring pursuant to
                  a plan) that has the result that  stockholders  of the Company
                  immediately  before such transaction cease to own at least 51%
                  of (x) the voting  stock of the Company or (y) any entity that
                  results   from  the   participation   of  the   Company  in  a
                  reorganization,  consolidation,  merger,  liquidation  or  any
                  other form of corporate transaction.

                  all or  substantially  all  the  property  and  assets  of the
                  Company to an unaffiliated third party.

                  (b) Section 4(a) shall not apply to the exercise by Minmet PLC
         of its  option  to  acquire  all of the  issued  share  capital  of the
         Brazilian mining subsidiary of the Company.

         Section 5.        Adjustment of Shares.

                  (a) If at any time while  unexercised  Options are outstanding
         hereunder,  there  shall be any  increase  or decrease in the number of
         issued and  outstanding  shares of Common Stock through the declaration
         of a stock  dividend or through  any  recapitalization  resulting  in a
         stock  split-up,  combination  or exchange of shares,  then and in such
         event appropriate  adjustment shall be made in the number of Shares and
         the exercise  price per Share  thereof then subject to this Option,  so
         that the same proportion of the Company's issued and outstanding shares
         shall remain subject to purchase at the same aggregate exercise price.

                  (b)  Except  as  otherwise   expressly  provided  herein,  the
         issuance by the Company of shares of its capital stock of any class, or
         securities  convertible  into  shares of  capital  stock of any  class,
         either in connection with direct sale or upon the exercise of rights or
         warrants  to  subscribe  therefor,  or upon  conversion  of  shares  or
         obligations  of the  Company  convertible  into  such  shares  or other
         securities, shall not affect, and no adjustment by reason thereof shall
         be made with respect to the number of or exercise  price of Shares then
         subject to this Option.

                  (c) Without  limiting the  generality  of the  foregoing,  the
         existence  of this  Option  shall not affect in any manner the right or
         power of the Company to make,  authorize or  consummate  (i) any or all
         adjustments, recapitalizations, reorganizations or other changes in the
         Company's  capital  structure  or its  business;  (ii)  any  merger  or
         consolidation  of the  Company;  (iii) any issue by the Company of debt
         securities,  or preferred or preference stock that would rank above the
         Shares subject to this Option;  (iv) the  dissolution or liquidation of
         the Company; (v) any sale, transfer or assignment of all or any part of
         the assets or business of the Company;  or (vi) any other corporate act
         or proceeding, whether of a similar character or otherwise.

         Section 6.  Non-Assignability of Option.  This Option may not be trans-
ferred or assigned by the Optionee  other than by will or by the laws of descent
and distribution.

         Section 7.  Issuance of Shares.  No person shall be, or have any rights
or privileges of, a stockholder of the Company with respect to any of the Shares
subject to this Option unless and until  certificates  representing  such Shares
have been issued and delivered to such person.  As a condition of an issuance of
a stock  certificate  for Shares,  the Company  may obtain  such  agreements  or
undertakings, if any, as it may deem necessary or advisable to assure compliance
with any provision of this Option Agreement or any law or regulation, including,
but not limited to, the following:

                  (a) The Optionee's representation and warranty to the Company,

         connection with, the distribution of any such Shares; and

                  (b) the Optionee's representation, warranty or agreement to be
         bound by any legends that are, in the opinion of the Company, necessary
         or  appropriate  to comply with the  provisions of any  securities  law
         deemed by the Company to be  applicable  to the  issuance of the Shares
         and to be endorsed upon the certificates representing the Shares.

         Section 8.        Administration of this Option.

                  (a) The determinations and the interpretation and construction

         Company shall have the authority,  in its sole and absolute  discretion

         and regulations  relating to this Option; (ii) to construe the terms of
         this  Option;  (iii) as provided in Section 5, upon  certain  events to

         perform all other acts  necessary or advisable for  administering  this
         Option,   including  the  delegation  of  such   ministerial  acts  and

         correct   any  defect  or  supply  any   omission  or   reconcile   any
         inconsistency  in this  Option 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 Company shall have full discretion
         to make all  determinations  on the matters referred to in this Section
         8(b), and such determinations shall be final, binding and conclusive.

         Section 9.  Government  Regulations.  The granting and exercise of this
Option and the  obligation of the Company to sell and deliver  Shares under this
Option,  shall be subject to all applicable laws, rules and regulations,  and to
such approvals by any governmental  agencies or national securities exchanges as
may be required.

this Option Agreement,  such notice must be in writing and personally  delivered
or sent by mail or delivery by a  nationally  recognized  courier  service.  Any
notice required or permitted to be delivered  under this Option  Agreement shall
be deemed to be delivered on the date on which it is personally  delivered,  or,

is  deposited  in the United  States  mail,  certified  or  registered,  postage
prepaid,  addressed  to the person who is to receive it at the address that such
person has previously  specified by written notice  delivered in accordance with
this  subsection.  The Company or the Optionee may change,  at any time and from
time to time, by written  notice to the other,  the address that was  previously
specified for receiving  notices.  Until changed in accordance  with this Option
Agreement,  the Company and the Optionee shall specify as its or his address for
receiving  notices the address set forth in this Option Agreement  pertaining to
the Shares to which such notice relates.

         position with or relationship to the Company or its subsidiaries.  This
         Option  shall not confer upon the  Optionee the right to continue as an
         employee,  consultant  or  advisor,  or  interfere  in any way with the
         rights  of  the  Company  to  terminate  the  Optionee's  status  as an
         employee, consultant or advisor.

                  (b) The  members of the Board shall not be liable for any act,

         this Option,  and members of the Board shall,  in addition to all other
         rights  of   indemnification   and   reimbursement,   be   entitled  to
         indemnification  and  reimbursement  by the  Company  in respect of any
         claim, loss, damage,  liability or expense (including  attorneys' fees,

         independent legal counsel selected by the Company,  and amounts paid in
         satisfaction of a judgment, except a judgment based on a finding of bad
         faith) arising from such claim, loss,  damage,  liability or expense to
         the full extent permitted by law and under any directors' and officers'
         liability or similar  insurance  coverage that may from time to time be

         this  Option.  The  Company  may  require  the  Optionee,  or any legal
         representative,  heir, legatee or distributee as a condition  precedent
         to such payment or issuance or transfer of Shares, to execute a release
         and receipt for such  payment or issuance or transfer of Shares in such
         form as it shall determine.

                  (d) Neither the Board nor the Company  guarantees  Shares from

                  (e) All expenses incident to the administration,  termination,
         or protection of this Option,  including, but not limited to, legal and
         accounting fees, shall be paid by the Company;  provided,  however, the
         Company may  recover  any and all  damages,  fees,  expenses  and costs
         arising out of any  actions  taken by the Company to enforce its rights
         under this Option.

                  (f)  Records  of the  Company  shall  be  conclusive  for  all
         purposes  under  this  Option,  unless  determined  by the  Board to be
         incorrect.

                  (h) If any  provision  of this Option is held to be illegal or
         invalid for any reason,  the illegality or invalidity  shall not affect
         the remaining  provisions of this Option,  but such provision  shall be
         fully severable,  and this Option shall be construed and enforced as if
         the  illegal  or invalid  provision  had never  been  included  in this
         Option.

         successors, and assigns, and upon the Board and its successors.

                  (k) The titles and  headings  of  Sections  are  included  for
         convenience  of  reference  only  and  are  not  to  be  considered  in

Dear Mr. Carmichael

You  currently  have an option (the  "Option")  to purchase  50,000  shares (the
"Shares") in Authoriszor Inc. (the "Company") at a price of $1.00 at any time up
to 1st April 2002.

The Company is negotiating to place shares to raise $10 - $15 million,  but this
is likely to take some time to  complete.  It would be in the best  interests of
the  Company  to have  some  working  capital  now;  accordingly  the  Board has
authorized me to approach  certain  warrant and option holders to invite them to
subscribe for their  entitlement to shares of Company common stock at a discount
of one-third to the issue price provided that such options are exercised in full
no later than the later of 31st January 2000 or five (5) business days after the
filing of the  Registration  Statement (as hereinafter  defined).  In your case,
this would mean  subscribing  for 50,000  Shares at an  exercise  price of 66.66
cents per share instead of $1.00.

The  Company  contemplates  filing  a  Form  S-8  registration   statement  (the
"Registration  Statement")  covering,  inter alia,  the  issuance of the Shares.
Promptly after the filing of the Registration  Statement,  the Company will send
you an Executive  Summary  relating,  inter alia, to the Stock Option  Agreement
with respect to the Option.  The Executive  Summary serves as a Prospectus under
the Registration Statement. You are urged not to exercise the Option until after
you have received the Executive Summary and had an opportunity to carefully read
the Executive Summary.

If you desire to exercise your Option at the reduced  exercise price pursuant to
the terms set forth  herein,  please sign the  enclosed  copy of this letter and
effect a telegraphic  transfer for $33,334 to the Company's  account at Comerica
Bank, 1300 North Park Center,  Dallas,  Texas  75265-0282;  ABA No.:  111000753;
Account Name: Toucan Gold Corporation;  Account No: 1880416886;  in full payment
for the issue of 50,000 shares of Company common stock.

Yours sincerely,



/s/ R.P. Jeffcock

Stock") of the Company  that have been or may be issued by the Company  pursuant
to certain Stock Option Agreements between the Company and David Carmichael,  L.
Clark  Arnold,  Robert P.  Jeffcock  and Robert A.  Pearce  (the  "Stock  Option
Agreements").

         You have  requested an opinion with respect to certain legal aspects of
the proposed offering. In connection therewith, we have examined and relied upon
the original,  or copies identified to our satisfaction,  of (1) the Certificate
of Incorporation of the Company,  as amended,  and the Bylaws of the Company, as
amended;  (2) minutes and records of the  corporate  proceedings  of the Company
with respect to the approval of the Stock Option Agreements,  the reservation of
350,000 Shares to be issued pursuant to the Stock Option Agreements and to which
the Registration  Statement relates,  the issuance of the shares of Common Stock
pursuant  to  the  Stock  Option   Agreements  and  related  matters;   (3)  the
Registration  Statement  and  exhibits  thereto,   including  the  Stock  Option
Agreements;  and (4) such other  documents  and  instruments  as we have  deemed
necessary  for the  expression  of  opinions  herein  contained.  In making  the
foregoing  examinations,  we have assumed the  genuineness of all signatures and
the  authenticity  of  all  documents  submitted  to us as  originals,  and  the
conformity to original  documents of all documents  submitted to us as certified
or photostatic copies. As to various questions of fact material to this opinion,

writings  of the  Company,  we have  relied,  to the  extent  deemed  reasonably

         Based  upon our  examination,  consideration  of, and  reliance  on the
documents and other matters described above, and assuming that:

         (1) the Shares to be sold and issued in the future  will be duly issued
and sold in accordance with the terms of the Stock Option Agreements;

         (2) the Company maintains an adequate number of authorized but unissued
shares  and/or  treasury  shares  available  for  issuance to those  persons who
purchase Shares pursuant to the Stock Option Agreements; and

         (3) the  consideration  for the  Shares  issued  pursuant  to the Stock
Option  Agreements is actually  received by the Company as provided in the Stock
Option Agreements and exceeds the par value of such shares;

then, we are of the opinion that,  the Shares issued or sold in accordance  with
the terms of the Stock Option Agreements will be duly and validly issued,  fully
paid and nonassessable.

         We hereby  consent to the  filing of this  opinion as an exhibit to the
Registration Statement and to references to us included in or made a part of the
