                               PROSPECTUS SUMMARY

         This  summary  highlights   information   contained  elsewhere  in,  or
incorporated by reference into, this  prospectus.  This summary does not contain
all the  information  you should  consider before buying shares in the offering.
You should read the entire prospectus carefully.

AUTHORISZOR INC.

         We provide a patent-pending  security  solution which secures corporate
information  while  enabling  businesses  to  provide  secure  access  to  their
corporate  Website and  applications and to conduct secure  communications  over
computer  networks and the Internet.  Our product  suite and processes  enable a
corporation to provide secure access to the information on its Web server to its
customers, suppliers, employees and public visitors from the Internet, according
to their pre-determined security profile.

         We  believe  our  solution  to be  innovatively  different  from  other
security solutions available today. Our solution provides security by securing a
customer's Website,  corporate  information assets and contents offline,  making
this  information  completely  inaccessible,  except  through the customer's Web
server. This process eliminates any direct contact between the person requesting
information and the corporate information assets.

         Each  request for  corporate  information  is  submitted to the server.
Then,  by using  silent  security  verification  not  apparent to the user,  the
Authoriszor  product  suite  identifies,  authenticates  and, if  authenticated,
authorizes the request to proceed. To be authenticated by a server which has our
product suite  installed,  the end user and the user's computer or terminal must
be  validated.   Our  profile  selector  ensures  that  the  person   requesting
information  is  only  provided  with   information  to  which  such  person  is
authorized.  Validated  requests for  information  are handled by the  protected
server,  which creates pseudo uniform resource locators that disconnect the name
of the data source and the location of the data on the corporate Web server.

         Our virtual  publisher then creates a response in the form of a virtual
Web page and, after ensuring that no changes have occurred in the environment or
device of the person  requesting  information  since the request was  submitted,
which  ensures  that  requestor  transmissions  have  not been  intercepted  nor
impersonated,  and that the requestor  identity is still the original  requestor
that  commenced the session,  sends the  requestor  the Web page of  information
off-line,  publishing it through a virtual page publishing  system.  Our product
suite then  immediately  destroys the virtual Web page response that was sent to
the person requesting information.

         The  benefit  of our  product  suite  is that it has been  designed  to
provide an added dimension of security to existing security products, such as:

         o        firewalls;
         o        virtual private networks;
         o        encryption;
         o        security tokens;
         o        smart cards; and
         o        biometrics.

         We  have  five  patent  applications   pending  in  the  U.S.  for  our
Authoriszor  product  suite.  We have  attempted to extend any  successful  U.S.
applications  into the UK and other  countries  pursuant  to the  processes  and
procedures  provided by the Paris  Convention  and are currently  evaluating the
necessity of extending any such successful U.S.  patents  pursuant to the Patent
Cooperation  treaties.  We have  copyrights  on all  aspects of the  Authoriszor
product suite and are in the process of applying for UK trademarks in respect of
the key  Authoriszor  logos  used for  branding.  We are also in the  process of
implementing  confidentiality  procedures and contractual  provisions to further
protect  our  proprietary  rights.   Additional  protection  for  the  software,
documentation  and other  written  materials is afforded by trade secret and, in
the U.S. only,  unfair  competition laws.  "AUTHORISZOR",  SZ Logo, "A Logo" and
"SECURES THE WEB" are trademarks or registered  trademarks of Authoriszor or its
subsidiaries in the United States and other countries.

         In addition,  the Company provides a range of consulting services which
enable organizations to assess their respective internet security infrastructure
needs  in the  light  of an  increasing  internet  security  risk  and  to  help
understand  how the Company's  software suite is designed to reduce the inherent
risks associated with internet.  In the event that a customer decides to install
the Company's  software  technology,  the consulting  services group are able to
provide  implementation and knowledge transfer  engagements that helps to ensure
the successful installation and configuration of the software solution.

         Our predecessor was  incorporated as a Colorado  corporation on January
20, 1989 under the name Starlight Acquisitions,  Inc. On May 10, 1996, Starlight
Acquisitions,  Inc.  acquired Toucan Mining Plc (then named Toucan Mining Ltd.),
incorporated in the Isle of Man, the holding company of a mining group operating
in South America.

         On July 29, 1996, Starlight Acquisitions,  Inc. was reincorporated as a
Delaware  corporation on under the name Toucan Gold Corporation.  Effective July
15, 1999, Toucan Mining Plc sold its sole operating  subsidiary to Minmet Plc, a
company  listed on the Irish Stock  Exchange and the London Stock  Exchange,  in
consideration for the issue of Minmet Plc ordinary shares, the grant of warrants
and other  consideration.  On July 22,  1999,  we acquired  all the issued share
capital of Authoriszor Limited,  which was then named ITIS Technologies Limited,
whose business comprised the basis of our current business.  On August 25, 1999,
our name was changed to  Authoriszor  Inc.  and the name of our  subsidiary  was
changed to Authoriszor Ltd.

         On  January  12,  2000,  Authoriszor  Holdings  Ltd.,  a newly  created
wholly-owned  subsidiary of Authoriszor  Inc.,  acquired the whole of the issued
share capital of Authoriszor Ltd. as part of an intra-group re-organization.

         On January 27, 2000, we sold our wholly-owned subsidiary, Toucan Mining
Plc, to Golden Ridge Group  Limited for an aggregate  consideration  of $809,750
((pound)500,000) in cash. On the same date, Toucan Mining Plc agreed to transfer
to Authoriszor  Inc. the beneficial  interest in 2,000,000  shares in Minmet Plc
and  warrants  to  subscribe  for  ordinary  shares of Minmet  Plc at a price of
(pound)0.08  per  share  for a further  7,700,000  shares  in  Minmet  Plc for a
consideration of (pound)1.

          Our principal  offices are located at One Van de Graaff  Drive,  Suite
502,  Burlington,  Massachusetts  01803-5188,  and our telephone number is (781)
359-9650.  Our  website is located  at  http://www.authoriszor.com.  Information

                                  RISK FACTORS

         You should  consider  carefully  the  following  risks before  making a
decision to buy our common stock.  If any of the following risks actually occur,
our business,  financial condition or results of operations would likely suffer.
In such case, the trading price of our common stock could  decline,  and you may
lose all or part of the money you paid to buy our common stock. The risk factors
below  do  not  necessarily  appear  in  order  of  importance.  The  risks  and
uncertainties  described below are not the only ones we face.  Additional  risks
and  uncertainties  not  presently  known to us may  also  impair  our  business
operations.  We have a history of losses and negative  cash flow and  anticipate
continued  losses.  Since our formation,  we have incurred  operating losses and
negative cash flow. As of December 31, 2000,  we had an  accumulated  deficit of
approximately $15,839,523. We also have experienced net losses during our entire
history prior to entering the Internet security business. We anticipate that our
business will generate  operating losses for the foreseeable future until we are
successful in generating significant additional revenues to support our level of
operating  expenses.  We cannot  assure you that we will ever achieve or sustain
profitability or that our operating  losses will not increase in the future.  If
we do  achieve  profitability,  we  cannot be  certain  that we can  sustain  or
increase  profitability  on a quarterly  or annual  basis in the future.  To the
extent we are unable to  achieve  profitability  in the  future,  our  business,
prospects, financial conditions and results of operations will suffer.

RISKS RELATED TO OUR BUSINESS

We expect our quarterly operating results to fluctuate.

         We anticipate that our quarterly  operating results will vary according
to several factors, any of which could have an adverse effect on sales. We are a
start-up  operation in an immature  market.  Our revenues will initially tend to
take  the  form of pilot  projects  with  large  organizations  leading  to full
acceptance only on proof of our  technology.  This may tend to lead to an uneven
revenue  stream.  This trend may  potentially  also be exacerbated by long sales
lead times resulting in delays in receiving revenues.

         We will  operate  with low backlog  levels for product  license  sales.
Consequently,  the volume of orders in a given  quarter will have a  significant
impact on the revenues for that quarter.  Since our expense  levels are based on
projected  revenue  expectations,   if  our  backlog  levels  fall  below  those
expectations, then losses may increase.

We anticipate a potential decline in margins in our market.

         As the network  management and security market  matures,  we anticipate
that there will be a move towards packaging of multiple  functional  elements at
"less than the sum of the parts" pricing. We believe that we will not experience
a decline in earnings if we can achieve our market share objectives in the early
market  phase  and can move  towards a higher  level of  service  based  revenue
streams as margins  decline.  Failure to achieve these two objectives would have
serious,  long term  consequences for our  profitability,  if any, and our share
price.

Rapidly  changing   technologies  may  render  our  product  suite  obsolete  or
unmarketable.

         The  network  management  and  security  market  is  subject  to  rapid
technological change and innovation.  Customer  requirements are also subject to
significant  short-term  changes.  As a result, we must  continuously  adapt and
improve  our  product  suite  in  response  to  changes  in  operating  systems,
application software,  computer and communications  hardware,  network software,
programming tools and computer language technology. The introduction of products
embodying  new  technologies  and the  emergence of new industry  standards  may
render some or all of our existing products obsolete or unmarketable.

         In  particular,   the  market  for  Internet,   Intranet  and  Extranet
applications  is very new and is evolving  rapidly.  Our operating  results will
depend upon our ability to remain  abreast of these  advances.  We cannot assure
you  that  we  will  be  successful  in  developing   new  products  or  product
enhancements  that  respond  to  technological  changes  and  evolving  industry
standards.  We also cannot be certain that we will not  experience  difficulties
that could delay or prevent successful development, introduction or marketing of
these  products,  or that the new products will  adequately  meet the developing
needs  of the  market  and  achieve  market  acceptance.  If we do  not  respond
adequately  to  the  need  for  developing  and   introducing  new  products  or
enhancements to our existing products in a timely manner in response to changing
market conditions or customer requirements,  our business, operating results and
financial condition could be materially adversely affected.

Our package of software may not be accepted as a proprietary standard.

         Our future  success will depend in part on the adoption of our software
package as a proprietary standard by potential  customers.  This adoption may be
jeopardized by a public perception that the use of client-side  software results
in a loss of  flexibility  and ease of access to software  systems.  Our view is
that our package of software is a valuable tool for assuring and enhancing tight
and  continuing  security,  and that other  commonly used Internet  capabilities
require the use of client software.  In order to utilize our package of software
to attain information security at a high level of confidentiality and integrity,
we must  persuade  customers  either  to adopt  our  package  of  software  as a
proprietary  standard or that our product  suite will  significantly  facilitate
migration  to a more secure  environment.  If we do not achieve  either of these
objectives,  then our business,  operating results and financial condition could
be materially adversely affected.

We face strong competition, especially in North America.

         We face strong  competition,  particularly  in North  America where the
majority of our  competitors are based. We expect our revenue to be derived from
sales of software security products, systems integration, consulting and support
services,  and sales of  hardware  and  other  products.  We face and  expect to
continue to face competition in each of these market areas from various existing
and  emerging  information  security  providers.  Many of these  companies  have
greater name recognition,  longer operating histories, larger customer bases and
significantly  greater  financial,  marketing,  sales  and other  resources.  We
generally do not seek exclusive  relationships  with our business and technology
partners;  these  partners may also compete with us from time to time. We expect
to face increasing  competitive  pressures from our current  competitors and new
market entrants. We cannot accurately predict the size of our market, and if our
market is not as large as we expect,  our business  prospects  will suffer.  The
markets for our product suite is rapidly  evolving and we cannot assure you that
the Internet or common public  protocols  will continue to be used to facilitate
communications  or that the market for network  management and security  systems
will continue to expand.  Continued growth of this market will depend,  in large
part,  upon  the  continued  expansion  of  Internet  usage  and the  number  of
organizations  adopting  or  expanding  intranets  and upon the ability of their
respective   infrastructures  or  complementary  products  and  services  to  be
developed in a timely manner. Consequently, if the network management, security,
Internet and intranet markets fail to grow at the rate that we anticipate,  then
our  future  business,  operating  results  and  financial  condition  could  be
materially adversely affected.

Our success depends on our ability to protect our proprietary technology.

         We rely on a  combination  of  copyright,  trademark,  service mark and
trade secret laws,  confidentiality  procedures and contractual  restrictions to
establish  and protect the  proprietary  rights in our  software  and  services.
However,  we will not be able to protect  our  intellectual  property  if we are
unable to  enforce  our rights or if we do not  detect  unauthorized  use of our
intellectual property. In addition, these legal protections only provide us with
limited protection. If we litigate to enforce our rights, it would be expensive,
divert management resources and may not be adequate to protect our business. Our
inability to protect our proprietary  technology  could have a material  adverse
effect  on  our  business,   prospects,   financial  condition  and  results  of
operations.

         We may not have  adequate  remedies for  infringement  by others of our
product  suite.  We have five patent  applications  pending in the U.S.  for our
Authoriszor product suite and we believe that such products may be patentable in
the U.S. However,  because patent applications in the U.S. are confidential,  we
cannot  rule  out  the  existence  of  earlier-filed   patent  applications  for
technology  similar or identical to our product suite, or the  possibility  that
another  party may first  secure  patent  protection  in  substantially  similar
technology.  Therefore, we cannot guarantee that our patent applications will be
successful.  We may attempt to extend any successful U.S.  applications into the
UK and other countries  through the Paris Convention and the Patent  Cooperation
treaties; however, patent applications for software are more difficult to obtain
in some countries outside the U.S. Even where patent protection is obtained,  we
cannot  guarantee that third parties will not oppose or otherwise  challenge the
patents  granted.  If we do not succeed in securing  patents in the U.S., UK and
other territories,  or if any granted patent is successfully challenged,  we may
not be able to prevent the  marketing  of products  similar to ours based on the
underlying technology by other persons in that territory.

         We cannot assure you that others will not develop technologies that are
similar or  superior  to our  technology.  Despite  our  efforts to protect  our
proprietary rights,  unauthorized uses of our product suite will be difficult to
prevent, and although we are unable to predict the extent to which piracy of our
software products may occur,  software piracy can be expected to be a persistent
problem.  In addition,  the laws of some foreign  countries  may not protect our
proprietary  rights  as fully as do the  laws of the  U.S.  and the UK.  We also
cannot assure you that our competitors  will not  independently  develop similar
technology.

         We may rely on technology that we license from third parties, including
software  that is  integrated  with and  into our  product  suite  and  which is
critical to the functionality of our product suite.  Should we lose the right to
incorporate  such software into our product suite,  we would be required to seek
substitute  software  products,  the lack of  which  or the use of  which  could
negatively affect the functionality and viability of our product suite.

         We cannot assure you that third parties will not claim  infringement by
us with respect to current or future products. We expect that software companies
will  increasingly be subject to  infringement  claims as the number of products
and competitors in our industry segment grows and the  functionality of products
in different industry segments overlaps.  Responding to such claims,  regardless
of merit, could be time consuming,  result in costly  litigation,  cause product
shipment  delays or require us to enter into  royalty or  licensing  agreements.
Such royalty or licensing agreements, if required, may not be available on terms
acceptable to us or at all, which could have a material  adverse effect upon our
business, operating results and financial condition.

         We do not have registered trademark protection for all logos we use. We
do not have trademarks for any of the Authoriszor  brand names/logos in the U.S.
We cannot  guarantee that any trademark  application for the  Authoriszor  brand
names/logos  will be approved by the relevant  governmental  authority.  Even if
appropriate  applications  were made and  approved,  third parties may oppose or
otherwise  challenge  such  applications  or  registrations.  Failure  to obtain
trademark  registrations  in the  territories  in which we intend to market  our
business  could  limit  our  ability  to use  the  brand  names/logos  in  those
territories.  While we are not aware of any encumbrances in our ownership of, or
that any third parties are infringing upon our intellectual  property rights and
we do not believe that the  Authoriszor  product suite  infringes upon any third
party  rights,  the  developers  of the product did not give  warranties  to the
effect  that there was no third party  infringement  when they  transferred  the
intellectual  property to us. Our success  depends on retaining  our current key
personnel and  attracting  additional  personnel,  particularly  in the areas of
management,  sales and distribution,  client support and technical services. Our
success will depend largely on the continuing  efforts of our executive officers
and senior  management,  especially those of Paul Ayres, our President and Chief
Executive Officer, and Andrew Cussons, our Chief Financial Officer. Our business
may be adversely  affected if the services of these officers or any of our other
key personnel become unavailable to us.

         We have increased our sales and distribution and  administrative  staff
in  the  UK  and  have  built   sales  and   distribution   and   administrative
infrastructures in the U.S. If we fail to attract and retain qualified personnel
to staff these  positions,  particularly in the U.S., our business and prospects
will likely be adversely affected.

         We are currently  expanding our technical  services staff and will need
to increase our staff further to support expected new clients. The initiation of
new clients,  the  integration  of our  security  solutions  and ongoing  client
support can be complex.  Accordingly,  we need highly  trained  client  support,
technical personnel and outside consultants. Hiring client support and technical
personnel  is very  competitive  in our  industry  due to the limited  number of
people available with the necessary  technical  skills and  understanding of our
software package. Our inability to attract,  hire, train or retain the number of
highly  qualified  client  support and  technical  services  personnel  that our
business  needs,  or the  inability to hire  qualified  outside  consultants  to
perform these tasks, may cause our business and prospects to suffer.

Our U.S. operation may not be successful.

         We  anticipate  that the main market for our product  suite will be the
U.S. Prior to the first quarter of 2000, our operations had been based solely in
the UK. We believe that our target  market,  the U.S.,  cannot  successfully  be
penetrated,  either geographically or culturally, by a small UK-based operation.
Additionally,  we believe that the presence of U.S.-based  employees in our U.S.
headquarters  operation  is a  basic  requirement  for  successful  U.S.  market
penetration.  Accordingly,  in the  first  quarter  of  2000,  we  opened a U.S.
operational  office. We cannot assure you that our planned U.S.  operations will
be successful.  If we fail to access our target market  quickly,  we may be at a
significant  competitive  disadvantage  against our  competitors.  A significant
threat to the  achievement  of our  marketing  goals is any delay in the time to
market of our product suite. We predict that delays in the marketing program may
result in an early  lead  being  gained by one or more  companies  that  already
supply Web security  products.  In that case,  differentiated  positioning  will
become more  important  and we will need to be more explicit in our marketing or
the chance of market share gain will be adversely  affected.  Our pricing policy
will also suffer as a result of any  attempt to win market  share and grow brand
from a weaker  position.  If we fail to achieve fast time to market in the U.S.,
our  business,  operating  results and financial  condition  could be materially
adversely affected.

Our product suite may be defective and we may face product liability lawsuits.

         Our product  suite will be used for  network  management  and  security
functions which may be critical to organizations  and, as a result, the eventual
sale and support of products by us may entail the risk of product  liability and
related  claims.  We intend to attempt to explicitly  limit our liability in our
contracts;   however,  we  cannot  guarantee  that  contractual  limitations  on
liability  will  protect us from  liability  in any of the  nations or states in
which we do  business.  We  currently  have no product  liability  insurance.  A
product  liability  claim  brought  against us could have a  materially  adverse
effect on our business, operating results and financial condition.

         Software  products as complex as those we offer may contain  undetected
errors or failures  when first  introduced or when new versions are released and
errors or failures  may also  emerge,  once any version has been in use for some
time. In particular, the personal computer hardware environment is characterized
by a wide variety of non-standard  configurations  that make pre-release testing
for  programming  or  compatibility  errors very  difficult and time  consuming.
Despite our testing we cannot assure you that errors could not result in adverse
publicity,  loss or delay in market  acceptance,  or claims by customers against
us,  any of which  could  have a  material  adverse  effect  upon our  business,
operating results and financial condition.




We have a  limited  operating  history  in the  area  of  Internet  and  network
security.

         We have been  engaged in our  current  Internet  and  network  security
business since July 22, 1999. Our activities have primarily been in research and
development,  and  elements  of our  product  suite  are in an  early  stage  of
development.  We have a limited  operating  history in the  Internet and network
security business upon which our performance and prospects can be evaluated.  We
face risks frequently encountered by developing businesses.  These risks include
our potential inability to compete with more established firms and to retain and
maintain  key  personnel,  as well as  uncertainty  as to which  areas we should
target for growth and expansion  and as to the source of funding for  operations
and expansion.

Our success depends on the continued growth in use of the Internet.

         Rapid  growth in the use of and  interest  in the  Internet is a recent
phenomenon.  We cannot assure you that  acceptance  and use of the Internet will
continue  to develop or that a  sufficient  base of users will emerge to support
our business.  Sales of our product suite will depend  largely on the widespread
acceptance and increased use of the Internet as a source of information and as a
vehicle for commerce and  business.  If use of the Internet does not continue to
grow or grows more slowly than we expect, or if the Internet infrastructure does
not  effectively  support growth that may occur,  our business will be adversely
affected.

         Due to the increasing popularity of the Internet,  laws and regulations
applicable  to  Internet  communications,   commerce,   advertising  and  direct
marketing are becoming more prevalent. The adoption or modification of such laws
or  regulations  could  inhibit  the growth of  Internet  use and  decrease  the
acceptance of the Internet as a  communications  and  commercial  medium,  which
could decrease  demand for our product suite and have a material  adverse effect
on our business, results of operations and financial condition.

Failure  to  raise  additional  capital  or  generate  the  significant  capital
necessary to expand our  operations  and invest in new products could reduce our
ability to compete and result in lower revenue

         We anticipate  that our existing  capital  resources  will enable us to
maintain  currently  planned  operations  for at least the next  twelve  months.
However,  we premise this  expectation on our current  operating plan, which may
change as a result of many factors. Consequently, we may need additional funding
sooner than anticipated. Our presumed inability to raise capital would seriously
harm our business and product development efforts. In addition, we may choose to
raise additional  capital due to market  conditions or strategic  considerations
even if we believe we have sufficient  funds for our current or future operating
plans.  To the extent  that  additional  capital is raised  through  the sale of
equity or other  securities,  the issuance of these  securities  could result in
dilution to our stockholders.  We currently have no credit facility or committed
sources  of  capital  other  than  cash  valued  as  of  December  31,  2000  at
approximately $19.8 million.

         To the extent operating and capital  resources are insufficient to meet
future  requirements,  we will have to raise  additional  funds to continue  the
development and  commercialization  of our technologies.  These funds may not be
available on favorable  terms, or at all. If adequate funds are not available on
attractive terms, we may be required to curtail  operations  significantly or to
obtain  funds  by  entering  into  financing,  supply  or  other  agreements  on
unattractive terms.

Our acquisitions and ventures may disrupt or otherwise have a negative impact on
our business.

         We intend to enter into new  business  opportunities  and  ventures  to
build marketing and distribution  capabilities.  Typically,  such  opportunities
require  extended  negotiations  and the  investment of a substantial  amount of
capital and will impose substantial burdens on our management  personnel and our
financial and operational  systems. We cannot assure you that such venture(s) or
acquisitions  will be  appropriately  integrated  or  ever  achieve  or  sustain
profitability.




We face risks in foreign markets.

         We own  subsidiaries,  conduct  operations and market our product suite
internationally. Conducting business in most countries will require us to become
familiar with and to comply with foreign laws,  rules,  regulations and customs.
We have limited  experience  conducting  foreign  business and we cannot  assure
investors  that we will be  successful.  Moreover,  our  failure to comply  with
foreign  laws,  rules  and  regulations  of which we are not  aware may harm the
development  of our  business.  Further  risks  are  inherent  in  international
operations, including the following:

         o        differing levels of Internet use in other countries;

         o        customers'   agreements   may  be  difficult  to  enforce  and
                  receivables  difficult to collect through a foreign  country's
                  legal system;

         o        foreign customers may have longer payment cycles;

         o        foreign  countries may tax our foreign income and tax rates in
                  certain  foreign  countries  may  exceed  those of the  United
                  States and  foreign  earnings  may be  subject to  withholding
                  requirements or the imposition of tariffs,  exchange  controls
                  or other restrictions;

         o        intellectual  property rights may be more difficult to enforce
                  in foreign countries;

         o        fluctuations  in exchange  rates may affect product demand and
                  may  adversely  affect  the  profitability  in US  dollars  of
                  products and services  provided by us in foreign markets where
                  payment  for our  product  suite and  services  is made in the
                  local currency;

         o        fluctuations  in  exchange  rates  may  adversely  affect  the
                  proceeds of the placement  that we deposited in pound sterling
                  denominated accounts.

         o        general  economic  conditions  in the  countries  in  which we
                  operate  could have an  adverse  effect on our  earnings  from
                  operations in those countries;

         o        unexpected changes in foreign laws or regulatory  requirements
                  may  occur,   which  could  interfere  with  our  business  or
                  operations;

         o        compliance  with a variety of foreign laws and regulations may
                  prove difficult; and

         o        an overlap of different tax  structures  may prove too complex
                  to administer effectively,

         There can be no  assurance  that any of these  factors  will not have a
material adverse effect on our business and results of operations.

RISKS RELATED TO OWNING OUR COMMON STOCK

The exercise of warrants  and options to purchase our shares will have  dilutive
effect.

         There are  currently  outstanding  warrants  and  options  to  purchase
2,896,413  shares  of our  common  stock.  There  are  additionally  options  to
purchase,  in the  aggregate,  992,284  shares of common  stock  available to be
issued under our 1999 and 2000 stock option  plans.  These  options and warrants
provide an opportunity  for holders to profit from a rise in the market price of
our shares of common stock with  resulting  dilution in the  ownership  interest
held by you.  Holders of these  securities  may opt to exercise them and receive
the  underlying  shares of common  stock at a time when we are seeking to obtain
additional capital by an offering.  As a result, the terms,  including price, on
which we may be able to obtain additional  capital could be adversely  affected.
We have  anti-takeover  defenses  that could  delay or  prevent a takeover  that
stockholders may consider favorable. We have 2,000,000 shares of preferred stock
authorized  in our  Certificate  of  Incorporation,  none of which are currently
issued  and   outstanding.   The  preferred   stock  may  be  issued  with  such
designations,  rights and  preferences as may be determined from time to time by
our Board.  Accordingly,  our Board is empowered,  without stockholder approval,
but subject to applicable  government  regulatory  restrictions  and  applicable
corporate  laws,  including  the  fiduciary  duties of our  directors,  to issue
preferred stock with dividend,  liquidation,  conversion, voting or other rights
senior to the holdings of shares of common stock. If issued, the preferred stock
could be utilized as a method of  discouraging,  delaying or preventing a change
in control. Although we have no present intention to issue any additional shares
of our  preferred  stock,  we  cannot  assure  you that we will not do so in the
future.

         We are also subject to certain  provisions of Delaware law (Section 203
of  the  Delaware  General  Corporation  Law)  which  may  have  the  effect  of
discouraging  unsolicited  takeover offers.  Our stock will likely be subject to
substantial  price and volume  fluctuations due to a number of factors,  some of
which are beyond our control. The market price of our shares of common stock may
be subject to wide  fluctuations.  Reasons for future  fluctuations  may include
variations in industry growth rates, general economic conditions,  divergence in
financial results from analysts' expectations,  changes in earnings estimates by
stock  market  analysts,  our size  relative to the market and other  events and
factors.  Stock prices and trading volumes for many  Internet-related  companies
fluctuate widely, often for reasons that may be unrelated to their businesses or
results of operations.  In addition,  international stock markets have from time
to time experienced  extreme price and volume  fluctuations  which have affected
the market  prices of  securities  and which have  often been  unrelated  to the
operating performance of the companies affected.

         These  broad  market  fluctuations,  as well as  general  economic  and
political conditions,  could adversely affect the market price for our shares of
common  stock.  We are  at  risk  of  securities  class  action  litigation  and
regulatory  inquiry due to our  expected  stock price  volatility.  In the past,
securities  class action  litigation and regulatory  inquiries have been brought
against a company  following  periods of  volatility  in the market price of its
securities.  In the  future  we  may be the  target  of  similar  litigation  or
inquiries. Even if groundless and ultimately unsuccessful, securities litigation
and regulatory inquiries may result in substantial costs and divert management's
attention  and  resources,  which may seriously  harm our  business,  prospects,
financial condition and results of operations and may also harm our reputation.

We face risks related to exchange rates.

         A  proportion  of our  revenues  are  expected to be received in non-US
currencies  and, in particular,  we anticipate that a proportion of our revenues
will be received in Euros.  This may give rise to an exchange  risk against U.S.
dollars.

         We may engage from time to time in foreign  exchange hedging in respect
of the principal  foreign  currencies in which our receivables are  denominated.
There can be no assurance that such hedging  activities will continue or will be
effective to limit the impact of any movements in exchange  rates on our results
or operations.

Our  executive  officers and directors in the  aggregate  control  approximately
26.3% of our voting stock.

         Our  directors and  executive  officers will together own  beneficially
approximately  26.3% of the issued  and  outstanding  shares of common  stock of
Authoriszor Inc.,  including options  exercisable  within 60 days of the date of
this prospectus by such directors and executive officers.  If these stockholders
were to vote all of their shares in a similar manner, they would have sufficient
voting power to significantly influence the outcome of any corporate transaction
or any matter submitted to the stockholders for approval, including the election
of directors, mergers, consolidations or the sale of all or substantially all of
our assets, and to prevent or cause a change in control.

                                 USE OF PROCEEDS

         We will not receive any  proceeds  from the sale of common stock by the
selling stockholders.





                   PLAN OF DISTRIBUTION; SELLING STOCKHOLDERS

         This  prospectus  relates to 2,271,933  shares of our common stock that

this  prospectus,  regarding  the  beneficial  ownership of shares of our common
stock by each selling stockholder.

*        Indicates less than 1%.

(1)      Unless otherwise indicated, to our knowledge,  the persons and entities
         named in the table  have sole  voting  and sole  investment  power with
         respect to all shares of our common stock beneficially  owned,  subject
         to community property laws where applicable. Represents those shares of
         common stock held by the selling  stockholders,  if any,  together with
         those  shares that such  selling  stockholder  has the right to acquire
         upon exercise of warrants or otherwise within 60 days.

(2)      Because  the  selling  stockholders  may sell all or a portion of their
         shares of common stock pursuant to this prospectus at any time and from
         time to time, no estimate can be made of the number of shares of common
         stock that each selling  stockholder  may retain upon completion of the
         offering by the selling  stockholders.  Therefore,  this table  assumes
         that all shares of our common stock offered by this  prospectus by each
         selling  stockholder are actually sold.  Such  presentation is based on
         17,526,784  shares of our common stock  outstanding  as of February 14,
         2001.

Placement Shares

         The shares of our  common  stock  beneficially  owned by certain of our
selling  stockholders  were  acquired on February  18,  2000,  in a placement of
2,727,273  shares of our common  stock at a price of $11.00 per share.  However,
certain selling  stockholders  have, in the period between the  effectiveness of
our registration statement, and now, sold shares in accordance with the "Plan of
Distribution; Selling Stockholders" section of the prospectus contained therein.
The original  placement was made  pursuant to Regulation S under the  Securities
Act in the United  Kingdom and Europe.  In  connection  with the  placement,  we
agreed to file the registration statement of which this prospectus forms a part.

         We agreed to grant  certain  registration  rights to the holders of our
shares from the placement under a Registration  Rights  Agreement dated February
16, 2000,  entered into in anticipation of the completion of the placement.  The
Registration Rights Agreement provides that we are obligated to prepare and file
with the  Securities and Exchange  Commission a registration  statement of which
this  prospectus  forms a part, with respect to the offer and sale of the shares
from the placement by the holders from time to time. See "Description of Capital
Stock-Registration Rights Agreement."

Warrant Shares

         The  remaining  shares of our common  stock  beneficially  owned by the
selling  stockholders  were  acquired  in a  merger  transaction  involving  the
acquisition  of Toucan  Mining Plc.  Certain  stockholders  of our  predecessor,
Starlight Acquisitions, Inc., received warrants to purchase our shares of common
stock.  The Starlight  warrants entitle their holders to purchase from us, on or
before the six month anniversary of the closing of the first  registration of an
offering of our securities pursuant to the Securities Act, 100,000 shares of our
common stock at the purchase price of $4.00 per share,  subject to adjustment as
provided in the Warrant Agreement.  These warrants have been exercised resulting
in the issuance of 100,000 shares of our common stock to the warrant holders.

         Starlight   warrant   holders  are   entitled  to  certain   "piggyback
registration"  rights,  which,  subject to certain limitations and restrictions,
will permit such Starlight  warrant holders to include their  Starlight  warrant
shares in this registration  statement.  However,  certain selling  stockholders
holding our warrant shares have, in the period between the  effectiveness of the
registration  statement,  of which this  prospectus  forms a part, and now, sold
shares in  accordance  with the  "Plan of  Distribution;  Selling  Stockholders"
section of the prospectus contained therein

         Except  as  specifically  set  forth  in this  prospectus,  none of the
selling  stockholders has, or within the past three years has had, any position,
office or other  material  relationship  with us or any of our  predecessors  or
affiliates.

         We have been advised by the selling  stockholders that they or, subject
to applicable law, their pledgees,  donees,  distributees,  transferees or other
successors in interest,  intend to sell all or a portion of the shares of common
stock offered by this prospectus from time to time:

         o        on the NASDAQ National Market;

         o        otherwise than on the NASDAQ National Market;

         o        in  negotiated  transactions  at  fixed  prices  which  may be
                  changed;

         o        at  market  prices  prevailing  at  the  time  of  sale  or at
                  reasonably related prices or at negotiated prices; or

         o        by a  combination  of the  foregoing  methods of sale,  any of
                  which may involve crosses and block transactions.

         The selling  stockholders  may effect such  transactions by selling the
shares of common stock to or through broker-dealers, and such broker-dealers may
receive  compensation in the form of discounts,  concessions or commissions from
the selling stockholders and/or the purchasers of the shares of common stock for
which  such  broker-dealers  may  act as  agent  or to  whom  they  may  sell as
principal,  or both.  We are not aware as of the date of this  prospectus of any
agreements between any of the selling  stockholders and any broker-dealers  with
respect to the sale of the shares of common stock offered by this prospectus. In
connection with  distributions  of the shares of common stock or otherwise,  the
selling stockholders may enter into hedging transactions with broker-dealers. In
connection with such  transactions,  broker-dealers may engage in short sales of
the shares of common stock  registered  under this  prospectus  in the course of
hedging  the  positions  they  assume  with  selling  stockholders.  The selling
stockholders  may also sell  shares of our common  stock  short and  deliver the
shares  of  common  stock  to  close  out  such  short  positions.  The  selling
stockholders   may  also  enter   into   option  or  other   transactions   with
broker-dealers  which require the delivery to the broker-dealer of the shares of
common stock  registered  under this  prospectus,  which the  broker-dealer  may
resell pursuant to this prospectus. The selling stockholders may also pledge the
shares of common  stock  registered  hereunder  to a broker or dealer and upon a
default,  the broker or dealer may effect sales of the pledged  shares of common
stock pursuant to this prospectus.

         The  selling  stockholders  and  any  broker,  dealer  or  other  agent
executing sell orders on behalf of the selling  stockholders may be deemed to be
"underwriters"  within  the  meaning  of the  Securities  Act,  in  which  event
commissions  received  by any such  broker,  dealer or agent  and  profit on any
resale of the shares of principal may be deemed to be  underwriting  commissions
under the Securities Act. Such commissions received by a broker, dealer or agent
may be in excess of customary compensation.  The shares of common stock may also
be sold in accordance  with Section 4(1) of the  Securities  Act or Rule 144 and
Rule 145 under the Securities Act.

         Information  as to  whether  underwriters  who may be  selected  by the
selling  stockholders,  or any other  broker-dealer,  is acting as  principal or
agent  for  the  selling  stockholders,  the  compensation  to  be  received  by
underwriters  who  may  be  selected  by  the  selling   stockholders,   or  any
broker-dealer, acting as principal or agent for the selling stockholders and the
compensation  to be  received  by  other  broker-dealers,  will,  to the  extent
required by law be set forth in a supplement to this  prospectus.  Any dealer or
broker  participating  in any distribution of the shares of our common stock may
be  required  to deliver a copy of this  prospectus,  including  the  prospectus
supplement,  if any, to any person who purchases any of the shares of our common
stock from or through such dealer or broker.

         All expenses of  registration  incurred in connection with the offering
will be borne by us. All  selling  and other  expenses  incurred  by the selling
stockholders will be borne by the selling stockholders.

         The selling  stockholders  will be subject to applicable  provisions of
the Securities  Exchange Act and its rules and  regulations,  including  without
limitation,  Rule 102 under  Regulation M, which provisions may limit the timing
of purchases  and sales of any of the common stock by the selling  stockholders.
Rule 102 under  Regulation  M  provides,  with  certain  exceptions,  that it is
unlawful for a selling  stockholder or its affiliated  purchaser to, directly or
indirectly,  bid for or  purchase  or attempt to induce any person to bid for or
purchase,  for an  account  in  which  the  selling  stockholder  or  affiliated
purchaser has a beneficial  interest in any  securities  that are the subject of
the distribution during the applicable restricted period under Regulation M. All
of the  foregoing  may affect the  marketability  of the common  stock.  We will
require  each  selling  stockholder,  and his or her  broker if  applicable,  to
provide a letter that  acknowledges  his compliance  with Regulation M under the
Securities  Exchange  Act  before  authorizing  the  transfer  of  such  selling
stockholder's shares of common stock.

         The selling  stockholders  may offer all of the shares of common  stock
for sale.  Further,  because it is possible that a significant  number of shares
could be sold at the  same  time  under  this  prospectus,  such  sales,  or the
possibility  thereof,  may have a  depressive  effect on the market price of our
common stock.

         We have agreed to indemnify the selling  stockholders  against  certain
liabilities  in  connection  with the  registration  statement,  of  which  this
prospectus is a part, including certain liabilities under the Securities Act.

              DISCLOSURE OF COMMISSION POSITION ON INDEMNIFICATION
                         FOR SECURITIES ACT LIABILITIES

         Our certificate of incorporation,  as amended,  and bylaws provide that
we will  indemnify  our  directors  to the full extent  permitted by the General
Corporation  Law of the State of Delaware  and may  indemnify  our  officers and
employees to such extent,  except that we will not be obligated to indemnify any
such person with respect to proceedings,  claims or actions initiated or brought
voluntarily  by any such  person and not by way of  defense,  without  our prior
written consent,  or for any amounts paid in settlement of an action indemnified
against by us without our prior written consent.

         In addition,  our certificate of incorporation,  as amended, and bylaws
provide  that  our  directors  will  not  be  personally  liable  to us  or  our
stockholders  for monetary  damages for breach of his or her fiduciary duty as a
director, except for liability:

         o        for any breach of the director's  duty of loyalty to us or our
                  stockholders;

         o        for acts or  omissions  not in good  faith  or  which  involve
                  intentional misconduct or a knowing violation of law;

         o        for  willful  or  negligent  conduct  in paying  dividends  or
                  repurchasing stock out of other than lawfully available funds;
                  or

         o        for  any  transaction  from  which  the  director  derives  an
                  improper personal benefit.

Reference is made to Section 145 of the General  Corporation Law of the State of
Delaware which provides for indemnification of directors and officers in certain
circumstances.  Section  145  requires  us to  indemnify  such  persons  against
expenses,   judgments,   fines,  settlements  and  other  amounts  actually  and
reasonably  incurred,  including  expenses of a derivative action, in connection
with any proceeding,  whether actual or threatened, to which any such person may
be made a party by reason of the fact that such person is or was our director or
executive  officer or a director or executive  officer of any of our  affiliated
enterprises,  provided  such  person  acted in good  faith and in a manner  such
person  reasonably  believed to be in or not opposed to our best  interests and,
with respect to any criminal proceeding,  has no reasonable cause to believe his
or her conduct was unlawful.

         We have entered into an employment  agreement  with Richard A. Langevin
under which we agreed to  indemnify  Mr.  Langevin and hold him  harmless,  at a
minimum in  accordance  with the  provisions  contained  in our  Certificate  of
Incorporation  and Bylaws,  against any losses,  claims,  damages,  liabilities,
costs,  expenses,  including advancing from time to time his attorney's fees and
expenses  in  advance  of the final  disposition  of any  claim,  action,  suit,
proceeding or investigation,  judgments, fines and amounts paid in settlement in
connection  with any  threatened or actual claim,  action,  suit,  proceeding or
investigation, whether civil, criminal or administrative, in which the executive
is, or is  threatened  to be, made a party by reason of having been our Director
or officer or serving or having  served at our request as a  director,  trustee,
officer,  employee or agent of another  corporation or of a  partnership,  joint
venture,  trust  or other  enterprise,  including  service  with  respect  to an
employee benefit plan, whether the basis of such proceeding is alleged action or
failure to act in an official capacity as a director,  trustee, officer employee
or agent,  provided that we will have choice of counsel in any such action.  Our
obligations under such  indemnification  provisions will survive the termination
of his  employment  agreement.  Notwithstanding  the  foregoing,  we will not be
obligated to indemnify Mr. Langevin beyond the extent  permissible under Section
145 of the Delaware General Corporation Law and other applicable law, including,
without limitation, applicable securities law.

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors,  officers, or persons controlling us pursuant
to the  foregoing  provisions,  we have been informed that in the opinion of the
SEC 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 us of
expenses  incurred or paid by a director,  officer or controlling  person in the
successful  defense  of any  action,  suit or  proceeding)  is  asserted  by any
director,  officer or controlling person in connection with the securities being
registered,  we will,  unless in the  opinion of our counsel the matter has been
settled by controlling precedent,  submit to a court of appropriate jurisdiction
the question  whether such  indemnification  by us is against  public  policy as
expressed in the Securities  Act and will be governed by the final  adjudication
of such issue.

ITEM 17. 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.  Notwithstanding  the  foregoing,  any
         increase or decrease in the volume of securities  offered (if the total
         dollar  value of  securities  offered  would not exceed  that which was
         registered) and any deviation from the low or high end of the estimated
         maximum offering range may be reflected in the form of prospectus filed
         with the  Commission  pursuant  to Rule  424(b)  if,  in the  aggregate
         offering price set forth in the "Calculation of Registration Fee" table
         in the effective registration statement; and

                  (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.

         (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.

         (4) 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 an employee benefit
plan's 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.

         (5)  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  provisions  referenced  in Item 15 of this
registration statement or otherwise, the Registrant has been advised that in the
opinion of the  Securities  and  Exchange  Commission  this  indemnification  is
against  public  policy as expressed in the  Securities  Act and is,  therefore,
unenforceable.  In the event  that a claim  for  indemnification  against  these
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 a 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 of whether the indemnification by it is against public
policy as expressed in the  Securities  Act of 1933, and will be governed by the
final adjudication of this issue.
