                                ABOUT DIVERSINET

Diversinet Corp. (formerly The Instant Publisher Inc.) was formed on December 8,
1993  through  the  amalgamation  of  The  Instant  Publisher  Inc. with Lombard
Consolidated  Resources  Inc.,  an  Ontario  corporation.  We  are  regulated in
accordance  with  the  Business  Corporation  Act  (Ontario).

Our  company  was  formed  under  the  laws  of  Ontario,  Canada. Our principal
executive offices are located at 2225 Sheppard Avenue East, Suite 1801, Toronto,
Ontario, M2J 5C2, Canada. Our telephone number is (416) 756-2324.

We  are  a  security  software  product  company  that  develops,  markets  and
distributes  wireless  security  infrastructure  solutions  that provide for the
secure  transmission  of  data  over wireless networks and devices. Our solution
encompasses  all  aspects  of  commercial  transaction  security  requirements,
covering  the  authentication  and  authorization  of  individuals involved, the
integrity  of the information being sent and the non-repudiation or legalization
of  the  transaction.

We  believe  we are a pioneer in providing security products for mobile commerce
over  wireless  networks  and  are  striving  to  become the leading provider of
wireless  security  solutions.  Our strategy to achieve this objective involves:
targeting  emerging  m-commerce  markets,  expanding  strategic partnerships and
sales  channel  relationships,  maintaining  a  leadership  position in terms of
products  and  research and development and building awareness of the Diversinet
brand.

We  develop  and  license  the Passport Certificate Server(R), Passport ONE(TM),
Passport  Authorization Product(TM) and Passport VPN computer software products,
which provide for the secure transmission of data over wireless networks as well
as  various  other  kinds  of  networks,  including  corporate  networks,
telecommunications systems and the Internet. The transmission of data over these
networks  is  known  as  "e-commerce".

The  Passport  Certificate  Server(R)  software  verifies  the identities of the
parties to an e-commerce transmission through the use of digital certificates so
that  unauthorized  persons  cannot  intercept  its  contents.

The  Passport  ONE(TM)  software  product  provides a single point of contact to
enable  the  security tools embedded in mobile devices. By providing application
providers,  enterprises, and operators a single security infrastructure solution
for  all mobile devices, Passport avoids the development time and infrastructure
costs  normally  associated  with  multiple  device  coverage.

The  Passport  Authorization  Product'  software issues digital permits that are
linked  to  the  holder's  digital certificate. The Diversinet digital permit is
designed  to  allow  digital  certificates to serve additional functions such as
authorizing  users  to  perform  specific  tasks once they have accessed a given
network.

Virtual  private  network  ("VPN")  software uses encryption to provide a secure
connection  through  the  Internet, establishing a "secure tunnel" through which
any  enterprise  data  can  travel.  VPNs  are  less expensive than true private
networks  using  dedicated  connections  and  can  use  digital  certificates to
securely  identify  and  authenticate  the  enterprise  server  and remote user.
Diversinet's  Passport  Wireless  VPN  combines  the  strength  of  public  key
infrastructure  (PKI) digital certificates with a robust, wireless-optimized VPN
solution.

We  believe  that  the Passport products offer a unique approach to facilitating
and securing commercial transactions and data transmissions over these networks.



                    ACQUISITION OF DSS SOFTWARE TECHNOLOGIES

In  early  January,  2003,  we acquired all of the capital stock of DSS Software
Technologies  ("DSS"),  a systems integration provider headquartered in Fremont,
California.  DSS  provides  technical  consulting services to tier one customers
including  financial, enterprise and technology companies such as Cisco Systems,
Lucent,  Oracle,  Sun  Microsystems  and  Wells  Fargo  in  the areas of systems
integration,  software  development,  and Enterprise Resource Planning "ERP" and
Customer Relationship Management "CRM" implementation. Consideration for the DSS
acquisition  was provided through a combination of cash payments and an earn-out
position,  plus  warrants,  provided  over  a  three-year  term.

We  expect  that  the  addition  of DSS' services suite will enhance our ongoing
strategy  to  provide  greater  depth  and  breadth  in  our product and service
offering.  Combined,  DSS  and  our  technical  and industry expertise can offer
integrated  solutions and full services offerings. We believe our acquisition of
DSS  will  strengthen  our  position  in the U.S. through expanded access to key
customers and the addition of a comprehensive line of services that will help us
to  better  address  rapidly  growing  demands for security in telecommunication
services.

The  synergy between the two companies is expected to provide the infrastructure
and  capability  to  expand  into new markets and convey a unique opportunity to
deliver  products  and  services that will meet the specific needs of enterprise
customers.

With  DSS's  professional services focus on high profile customers in our target
markets  (enterprise,  financial,  et  cetera)  our  complementary  skill  sets
(application  development  and  wireless),  and a U.S. sales force, the combined
company  can  provide technical consulting services to companies in the areas of
system  integration, software development, and ERP and CRM implementation, which
are  all  natural  extensions  of  wireless  and  require  enhanced  security.

DSS's  operations have been integrated with ours as a wholly owned subsidiary of
Diversinet,  and  DSS  is  the  principal  office  for  our U.S. operations. The
purchase  of  DSS  was  accounted for using the purchase method and consolidated
financial  statements  have  been  prepared.

                                  THE OFFERING

Certain of our shareholders are offering the following securities for sale under
this  prospectus:

     -    5,990,000  common  shares,  and
     -    770,000  common  shares  issuable  upon  the exercise of the warrants.

There  are  a total of 6,760,000 common shares issued and common shares issuable
pursuant  to  this  registration  statement.

We are not offering or selling any securities under this prospectus and will not
receive  any  proceeds from the sale of the selling shareholder's securities. We
may  receive  up to U.S. $851,000 upon the exercise of the warrants. However, we
will  pay  all  costs  associated  with  this  prospectus.



                                  RISK FACTORS

The  common  shares  offered  by this prospectus are speculative, involve a high
degree  of  risk  and should only be purchased by persons who can afford to lose
their  entire  investment.  You  should therefore carefully review the following
risk factors, as well as all of the other information in this prospectus, before
investing  in  the  securities  offered  by  this  prospectus.

                         RISKS RELATING TO OUR BUSINESS

WE  HAVE  LOST  MONEY  IN  THE  PAST,  WE  HAVE  REALIZED  MINIMAL REVENUES FROM
CONTINUING OPERATIONS AND WE EXPECT TO CONTINUE TO SUSTAIN LOSSES IN THE FUTURE.
We  have  generated  minimal revenue to date from the licensing of our products.
For the six months ended April 30, 2003, we posted a net loss of $3,198,000. For
the  year  ended  October  31,  2002, we posted a net loss of $6,397,000 and for
October  31,  2001,  we  posted  a  net loss of $18,900,000. For the years ended
October  31,  2000  and  October  31, 1999, we had net losses of $15,027,000 and
$14,111,000,  respectively.  We  generated licensing revenue of $314,000 for the
six  months ended April 30, 2003, $1,118,000 in the year ended October 31, 2002,
$1,221,000  in  the  year  ended  October 31, 2001, $2,636,000 in the year ended
October  31,  2000  and $246,000 in the year ended October 31, 1999. The revenue
represents  the  initial  licensing  of  our  Passport Certificate Server(R) and
Passport  Authorization Product(TM) together with related professional services.
For the six months ended April 30, 2003, we also generated consulting revenue of
$3,553,000 through our newly acquired consulting services division, DSS Software
Technologies.  During  fiscal  2001,  40%  of our revenue was generated from one
customer.  During  fiscal  2002,  28% of revenue was generated from one customer
although  not  the  same  customer  as  in  fiscal  2001, and 54% of revenue was
generated  from  three  customers.  To  date,  licensing our products to various
customers  and  providing  them with related professional services has generated
our  revenues.  We  cannot  provide assurance that recurring revenues will arise
from these license agreements. The auditors' reports on our October 31, 2001 and
2002  consolidated  financial  statements  included additional comments for U.S.
readers that states that conditions and events exist that cast substantial doubt
on  our  ability  to  continue  as  a  going concern. The consolidated financial
statements  do not include any adjustments that might result from the outcome of
that  uncertainty.

OUR  BUSINESS PLAN IS DEPENDENT UPON CUSTOMER ADOPTION AND COMMERCIAL DEPLOYMENT
OF  OUR  PRODUCTS.  Our  ability to continue operations is also dependent on the
acceptance  of  our  security  products  and  the  adoption of transaction-based
applications  using  public key infrastructure-based security (also known in the
industry  as PKI-based security) over wireless networks as an accepted method of
commerce  in  sufficient  volume  for us to generate enough revenues to fund our
expenses  and  capital requirements. The wireless mobile commerce market is in a
very  early  stage,  and it may not develop to a sufficient level to support our
business.

Our  products  are  marketed  to  large  companies  and government agencies. The
implementation  of  our  products by these entities typically involves a lengthy
education  process  and  a  significant  technical  evaluation and commitment of
capital  and other resources. This process is also subject to the risk of delays
associated with customers' internal budgeting and other procedures for approving
large capital expenditures, deploying new technologies within their networks and
testing  and accepting new technologies that affect key operations. As a result,
the associated sales and implementation cycles can be lengthy. Our quarterly and
annual  operating  results could be materially harmed if orders forecasted for a
specific  customer  for  a  particular  quarter  are  not  realized.

Many  of  our  early licensing agreements permitted our customers to examine and
test  our  products with no initial up-front payments to us. These customers are
not  required  to  make  payments  to us until they begin to use our product for
commercial purposes. In certain cases, we also enter into evaluation agreements,
whereby  potential  customers  may examine our software products for a specified
period of time with no payment to us. Our current licensing agreements typically
require  the  customer  to  pay  a  license  fee  attributable  to  the software
components  and  the development toolkit and upon shipment of these items to the
customer,  although  until early in fiscal 2000 we generally waived the up-front
fee.

PRODUCT  AND  MARKET  CONDITIONS.  General  economic  conditions  may  have  a
significant  impact  on  our  ability to generate sales for our products. During
fiscal  2002  and  2001,  we  experienced  decreased activity from our potential
customers,  and generally the adoption of wireless services has not proceeded as
rapidly  as  previously expected. As a result, our revenue in 2002 declined from
fiscal 2001 levels and may decline even further in the near future.

FOREIGN  EXCHANGE.  Our  functional  currency  is  the  Canadian  dollar.  Sales
generated  outside Canada are generally denominated in U.S. dollars. Furthermore
the  majority  of  DSS's  revenues  and  costs  from  operations  are



denominated  in  U.S.  dollars.  During  fiscal  2002  and 2003 year to date, we
incurred  most  of  our  expenses  in  Canadian  dollars, but we also incurred a
portion  of  our  expenses  in  foreign currencies including U.S. dollars, Pound
Sterling  and  Hong  Kong  dollars.  Changes  in  the  value of these currencies
relative  to  the Canadian dollar may result in currency losses that may have an
adverse  effect  on  our  operating  results.  With the completion of our recent
financing  in  June 2003, we have a portion of our cash resources in U.S. dollar
term  deposits.  To  date  we have not entered into any foreign currency hedging
activities.

WE  MAY  NOT  BE  SUCCESSFUL  IF  WE FAIL TO RETAIN OUR KEY TECHNICAL PERSONNEL.
During  September  2001,  we  substantially  reduced our headcount and curtailed
certain sales and marketing activities, particularly in the U.S. During 2002 and
2003, we continued to review our cost structure and have continued to reduce our
headcount.  Workforce  reductions may have a detrimental effect on the morale of
remaining employees, impeding their performance levels. In addition, our ability
to  attract  potential  new employees in the future may suffer if our reputation
was  hurt  by  this  staff  reduction.

We  currently have five senior officers and 66 employees and contractors. We may
not be able to improve our products or create new products if we lose any of our
key  employees or contractors. The contract with our CEO, Mr. Nagy Moustafa, had
a  term  of five years, commencing September 29, 1997, and has been renewed on a
year  to  year  basis.  None  of our other employment agreements has a specified
term.  We  do  not  maintain  key  person  life insurance policies on any of our
employees.  Skilled technical personnel can be difficult to attract depending on
the strength of the economy and competitive opportunities. We may not be able to
retain  our  current  employees  if  they  receive  better job offers from other
employers.  The  weakened  economy through 2001, 2002 and 2003 may not alleviate
this  risk  in  the  future.

WE  ARE INVOLVED IN LITIGATION WHICH COULD RESULT IN JUDGMENTS AGAINST US WHICH,
IN  THE  AGGREGATE,  COULD  TOTAL MORE THAN OUR COMBINED CURRENT ASSETS, WORKING
CAPITAL AND NET ASSETS. There are currently four material claims pending against
us.  If we lose any of these suits or enter into settlements requiring us to pay
cash  or  issue  any  of our common shares, our liquidity and financial position
will  be  adversely  affected  and  our  shareholders' ownership may be diluted.

We  have  been sued, along with other individuals and corporations, by Silva Run
Worldwide  Ltd. in connection with Silva Run's purchase of 212,500 common shares
(850,000  common  shares  prior  to a one for four reverse split in May 1997) in
1995 for a purchase price of U.S. $3,700,000. Silva Run is seeking to cancel the
stock  purchase  and  reimbursement  of the U.S. $3,700,000 purchase price, plus
interest,  attorneys' fees and costs. Silva Run has alleged that we, directly or
as  the  control  person of other defendants, violated certain provisions of the
Securities  Act of 1933, as amended, and the Securities Exchange Act of 1934, as
amended.  Kaye  Scholer,  our  former  attorneys,  were  successful  on  their
application to withdraw as counsel. Kaye Scholer sought an order directing us to
pay  Kaye Scholer's fees and expenses. The fee dispute was heard in January 2003
and  Judge Patterson entered his decision on May 12, 2003, ordering us to pay to
Kaye  Scholer  its  outstanding  fees. We are currently appealing this decision.

In  May  2000  we  were  sued,  along with our wholly-owned Barbados subsidiary,
Instant  Publisher  Ltd. The plaintiff is seeking damages of U.S. $1,533,950 for
breach  of  an  October  25,  1995  dealer  agreement with our previous printing
business  regarding  the distribution of printing equipment, and damages of U.S.
$25,000,000  for  loss  of  reputation and loss of opportunity, pre-judgment and
post-judgment  interest,  and  costs.

In  April, 2003, we were served with a claim filed in the Ontario Superior Court
of  Justice,  Small  Claims  Court, by Michael Crerar, a former employee who was
terminated without cause on February 28, 2003. Mr. Crerar claims that Diversinet
breached his employment contract, that he was wrongfully terminated, and that he
failed to receive reasonable notice of his termination. Mr. Crerar seeks special
damages in the sum of $73,266.68, but, having brought the matter in Small Claims
Court,  is  limited  to  a  maximum  award  of  $10,000.

In  July, 2003, we were sued in the Ontario Superior Court of Justice by Annette
Hamilton  and  Farhad Pezeshki, two former employees who claim, inter alia, that
each  was terminated, while on short term disability, in a manner that exhibited
bad  faith  and  unfair dealings. Annette Hamilton is seeking against Diversinet
$125,000  in  special,  general,  punitive  and exemplary damages. Farhad (Adam)
Pezeshki  is  seeking  against Diversinet $350,000 in special, general, punitive
and  exemplary  damages.

WE HAVE LIMITED EXPERIENCE IN THE WIRELESS INTERNET SECURITY SOFTWARE FIELD, AND
WE  ARE  THEREFORE  SUBJECT TO RISKS INHERENT IN ESTABLISHING A NEW BUSINESS. We
have  been  in  the  wireless  Internet  security  software  field  since fiscal



1997, and we have only generated minimal revenues from this business. We are not
sufficiently established to fully evaluate or forecast our prospects, and we are
subject  to  the  risks  inherent  in  establishing  a  new business enterprise.

WE ARE DEPENDENT ON THE ADOPTION OF TRANSACTION-BASED APPLICATIONS OVER WIRELESS
NETWORKS  AS  AN  ACCEPTED METHOD OF COMMERCE. In order for us to be successful,
transaction-based  applications  using PKI-based security over wireless networks
must  be adopted as a means of trusted and secure communications and commerce to
a sufficient extent and within a reasonable time frame, particularly considering
our  existing  financial  resources  and future capital needs. Since trusted and
secure  communications  and commerce over these networks is new and evolving, it
is  difficult  to  predict  with  any  assurance the size of this market and its
growth  rate,  if  any.

If  the  market for trusted and secure communications and commerce utilizing PKI
over  these  networks fails to develop or develops more slowly than expected, we
may  have  difficulty  selling  products  or  generating  sufficient revenues to
support  our  business.

OUR  ABILITY  TO KEEP PACE WITH THE RAPID TECHNOLOGICAL CHANGES AND FREQUENT NEW
PRODUCT  INTRODUCTIONS COMMON IN THE ELECTRONIC COMMERCE INDUSTRY WILL DETERMINE
OUR  ABILITY  TO REMAIN COMPETITIVE AND AFFECT THE VIABILITY OF OUR PRODUCTS. To
succeed  in  the  mobile  e-commerce  business,  we believe that we will have to
continuously  improve  the performance, features and reliability of our products
and  be  the  first  to the market with new products or enhancements to existing
products.  We  cannot  provide  assurance  that  we  will be able to improve our
products  in  a  timely  manner.  The  emerging market for security products for
mobile e-commerce is characterized by rapid technological developments, frequent
new  product  introductions  and evolving industry standards. We anticipate this
evolution  will also occur in the mobile e-commerce market in which we focus our
technological  developments.  The  adoption  of  new  standards, or the informal
adoption  of  certain  standards  by  a  significant  percentage of the computer
security  and  related industries, could require us to reconfigure our products.
We may not be able to counter challenges to our current products or to introduce
product  offerings  that  keep pace with the technological changes introduced by
competitors  or  persons  seeking  to  breach  information  security. We are not
currently  aware of any significant new technologies either under development or
about  to  be  introduced  in  the  mobile  e-commerce  security  field.

THE  HIGHLY COMPETITIVE NATURE OF THE ELECTRONIC COMMERCE FIELD COULD PREVENT US
FROM  ACHIEVING  SUCCESS.  Our  products  are  targeted  at  the new and rapidly
evolving  market  for  authentication  and  authorization  products for wireless
electronic  commerce  and  telecommunications.  This  market  is  not mature. We
anticipate  that  it  will be intensely competitive, subject to rapid change and
significantly affected by new product and service introductions and other market
activities  of  industry  participants.  Many  of  our competitors and potential
competitors  have  a  longer operating history, greater name recognition, larger
installed  customer  base  and  significantly  greater  financial, technical and
marketing  resources  than  we have. As a result, they may be able to adapt more
quickly  to  new  or emerging technologies and changes in customer requirements,
and  they  could  therefore  render  our  technologies  and  products  obsolete.

Because  of  the  broad  potential  application  of  our  authentication  and
authorization  software,  we  compete  with  vendors  offering  a  wide range of
computer  security  products.  These  competitors  include Entrust Technologies,
VeriSign,  Certicom,  Baltimore Technologies and RSA Security. There also may be
other  potential  entrants  to  the  market  of  whom  we  are  not  yet  aware.

OUR LICENSING REVENUES ARE DEPENDENT ON OUR CUSTOMERS' ACCEPTANCE AND USE OF OUR
SOFTWARE  PRODUCTS,  AND  WE  EXPECT  OUR SALES CYCLE TO BE LENGTHY. Many of our
early  licensing  agreements  permitted  our  customers  to examine and test our
products  with  no  initial  up-front  payments  to  us. These customers are not
required  to  make  payments  to  us  until  they  begin  to use our product for
commercial  purposes. We also enter into evaluation agreements in certain cases,
whereby  potential  customers  may examine our software products for a specified
period of time with no payment to us. Our current licensing agreements typically
require  the  customer  to  pay  a  license  fee  attributable  to  the software
components  and  the development toolkit and upon shipment of these items to the
customer,  although  until early in fiscal 2000 we generally waived the up-front
fee.

Customers cannot simply license our products and begin using them immediately in
their  businesses.  Making  our  products  work  with  a  particular  customer's
application  may  be  a  complex, expensive and, in certain cases, an ultimately
unsuccessful  process.  This  process  may  also  require  the  customer to make
significant  commitments  of  time  and  money.  Based  on  discussions with our
customers,  we  believe  that  a  customer's required cycle of testing, internal
approval  and  network  modifications  can  reasonably take between six and nine
months  or  longer.  Therefore,  we  expect our sales cycle, or the time between
entering  into  a  license  agreement  and  when  we  begin to receive



recurring  revenue,  to  be  six  to  nine months or longer. Also, the amount of
revenue  can  be  very  limited  until  the customer's product is made generally
available  and  adopted.  Our  sales  are also subject to significant risks over
which  we  have little or no control, including customers' budgetary constraints
and  internal  acceptance  procedures  regarding  security-related  matters.

TWO  MAJOR ENCRYPTION TECHNOLOGY VENDORS SERVICE OUR AREA OF BUSINESS, AND IF WE
ARE  UNABLE TO LICENSE ENCRYPTION TECHNOLOGY FROM AT LEAST ONE OF THEM, IT WOULD
CAUSE  A  SIGNIFICANT  DISRUPTION TO OUR BUSINESS. Our current product offerings
include  encryption  technology  that  we  source from a third-party vendor, RSA
Security,  an  encryption  technology  vendor  who services the wireless and the
e-commerce  security  market.  The  term  of  each  licensing  arrangement  is
open-ended.  Encryption  technology  is  currently available from other vendors;
however,  if  this  agreement  is  terminated  for  any reason, we would have to
license  encryption  technology from an alternative vendor, and there might be a
significant  disruption  to  our  business.

Our success will depend in part on our continued ability to have access to these
and  other  technologies  that  are  important  to our existing products and may
become  important to products we may develop in the future. We cannot be certain
that we will be able to procure or use any necessary technology on terms similar
to  existing  licenses.

WE  LACK EXPERIENCE IN SALES AND MARKETING, AND DEPEND ON OUR RELATIONSHIPS WITH
MORE  ESTABLISHED  CORPORATIONS TO ASSIST IN SELLING AND MARKETING OUR PRODUCTS.
We  have  limited  sales  and  marketing  experience  and  limited money to fund
marketing.  A  significant  part  of  our business strategy is to form strategic
relationships with more established companies to expose our products to a larger
customer  base than we could reach through direct sales and marketing force. Our
existing relationships have not resulted in any significant revenues to date and
may  not  result  in  any  revenues  in  the  future.

As  a  result of our emphasis on these relationships, our success will partially
depend  on  both  the  ultimate  success of the third parties with which we have
these  relationships  and  the  ability  of  these  third  parties to market our
products  and  services  successfully.

In the past, we have concentrated our sales and marketing efforts on application
service  providers.  This  strategy  has lead to no commercial deployments. As a
result  and due to some success experienced by us in Hong Kong, we are focussing
our  efforts on working to establish the necessary infrastructure first. We have
jointly  developed  Mobile e-Cert with Hongkong Post. Hongkong Post will support
the  Mobile  e-Certs  through  its  Mobile  Certification  Authority  and mobile
operators will act as the Registration Authorities for the authentication of the
identity  of  Mobile  e-Cert  subscribers. Hongkong Post is the first recognized
public  Certification  Authority  in  Hong Kong. Hutchinson, the largest and the
leading  mobile  operator  in  Hong Kong, has been appointed the first certified
Registration  Authority  for  the  registration  of  Hongkong Post Mobile e-Cert
digital certificates to mobile users. This appointment also marks the first time
worldwide  a  mobile  operator  is  acting  as  a Registration Authority for the
issuance  of  wireless  digital  certificates.  After  this  was  successfully
accomplished,  we  have been working with application service providers who will
develop  applications  that  will  have  our  software embedded and will utilize
Mobile  e-Cert.

We  cannot  provide  assurance that we will be able to enter into additional, or
maintain our existing, strategic relationships on commercially reasonable terms,
if  at  all.  Our failure to do so would require us to devote substantially more
resources to the distribution, sales and marketing of our products and services.
Also,  these strategic relationships do not afford us any exclusive marketing or
distribution rights. The third parties may reduce their commitments to us in the
future  or  pursue  alternative  technologies.

THE  NATURE  OF  OUR  PRODUCTS SUBJECTS US TO PRODUCT LIABILITY RISKS, POTENTIAL
LOST  REVENUES  AND  ADVERSE  PUBLICITY  IN  THE  EVENT  OF PRODUCT FAILURE. Our
customers  may  rely  on our products to prevent unauthorized access to computer
networks.  Malfunctions  or  design  defects  of  our  products  could:

     -    cause interruptions, delays or cessation of services to our customers
     -    result in product returns
     -    result in liability for damages
     -    adversely  affect  the  market's perception of the security offered by
          our product, resulting in a lack of demand for our products
     -    require  us  to  make  significant  expenditures  of  capital or other
          resources to alleviate the problem.



OUR  LICENSE  AGREEMENTS  MAY  NOT  BE  ADEQUATE TO LIMIT OUR LIABILITY. A large
number  of  claims by our customers could subject us to significant liability as
well as limit the demand for our products. In most cases our license and support
agreements  attempt  to limit our liability to the total amount of the licensing
and  support fees paid during the twelve-month period preceding an alleged error
in  or  failure  of  our  software. This contractual provision may not always be
enforceable.  Courts have held that contractual limitations on liability of this
type,  or  the  "shrink-wrap licenses" in which they are sometimes embodied, are
unenforceable  because  the  licensee  does  not  sign  them.  If these contract
provisions  limiting our liability are not enforceable, we could be obligated to
pay  significant  damages  resulting  from  customer  claims.

IF COMPUTER HACKERS FIND WAYS TO CIRCUMVENT OUR PRODUCTS, OUR PRODUCTS WOULD NOT
PERFORM  THEIR ESSENTIAL FUNCTION. Any compromise of the security offered by our
products, in a single incident or a series of incidents, would make our products
less  attractive  to  our customers. Software error or failure may result from a
hacker  seeking  unauthorized  access to a computer network. The methods used by
hackers  are  evolving  rapidly  and generally are not recognized until they are
launched  against  one  or  more  systems.  We are unable to anticipate hackers'
tactics.  The publicity surrounding any security breaches could adversely affect
the  public  perception  of  the  security  offered  by  our  authentication and
authorization  products  and make it more difficult for us to sell our products.

TECHNICAL  ADVANCES  IN  THE  INFORMATION  SECURITY MARKET MAY MAKE OUR PRODUCTS
OBSOLETE.  Our  products  are  based on PKI technology and depend in part on the
application  of  certain  mathematical  principles  forming  the  basis  of  the
encryption technology that we license and embed in our products. Any significant
advance  in  techniques  for decoding or cracking encrypted computer information
could  render  our  products  obsolete  or  unmarketable.

Our PKI products use algorithms, or mathematical formulae, to encrypt and secure
information.  The  security  afforded  by  our  products  is  predicated  on the
assumption  that  these  mathematical formulae are very difficult to solve. This
assumption is based on the fact that years of theoretical and empirical research
by  leading mathematicians have not resulted in any efficient solutions to these
problems.  There  can  be  no  assurance, however, that future research will not
uncover  efficient  solutions  to  these  problems.

Also,  even if no breakthrough in solving these problems is discovered, they may
eventually  be  solved by computer systems having sufficient speed and power. If
improved  techniques  for  decoding  encrypted information are developed or made
possible  by  the  increased  availability  of powerful computing resources, our
products  could  be  rendered  obsolete.

WE  MIGHT  NOT  BE ABLE TO ENFORCE OUR INTELLECTUAL PROPERTY RIGHTS. Our success
depends  significantly  upon  our  proprietary  technology,  and  our  means  of
protecting our proprietary and intellectual property rights may not be adequate.
We  rely  on  a  combination  of  patent  and  trademark  laws,  trade  secrets,
confidentiality agreements and contractual provisions to protect our proprietary
rights. We have two U.S. patents, which will be in effect until August 22, 2017,
and  one  patent  granted  in  Israel  in  effect  until  2021,  as  well  as 14
applications  pending  in  Europe,  Israel,  U.S.  and Canada. We cannot provide
assurance  that  any  of our applications will be approved, that any new patents
will  be  issued, that we will develop proprietary products or technologies that
are  subject  to  patent protection, that any issued patent will provide us with
any  competitive  advantages  or  will  not  be  challenged  by  third  parties.
Furthermore,  we  cannot  provide  assurance that the patents of others will not
have  a  material adverse effect on our business and operating results. There is
also  a risk that our competitors will independently develop similar technology,
duplicate  our  products  or  design  around  our  patents or other intellectual
property  rights.

If  our  technology  or  products were determined to infringe upon the rights of
others,  we  would  be required to obtain licenses to use that technology. If we
are  not  able  to obtain a license in a timely manner on acceptable terms or at
all,  we  may  have  to  stop  producing  our  product  until  we can develop an
alternative  that  does  not  infringe  the  rights  of  others.

Patent  disputes  are common in technology-related industries. We cannot provide
any  assurance  that we will have the financial resources to enforce or defend a
patent  infringement or proprietary rights action. As the number of products and
competitors  in  our target markets grows, the likelihood of infringement claims
also increases. Any claims or litigation may be time-consuming and costly, cause
product  shipment  delays or require us to redesign our product or require us to
enter  into  royalty  or  licensing agreements. Any of these events could have a
material  adverse  effect  on  our  business  and operating results. Despite our
efforts  to  protect our proprietary rights, unauthorized parties may attempt to
copy aspects of our products or to use our proprietary information and software.



In  addition,  the laws of some foreign countries do not protect proprietary and
intellectual  property rights to as great an extent as do the laws of Canada and
the  U.S.

WE HAVE FOCUSED OUR SALES AND MARKETING EFFORTS IN ASIA AND HONG KONG. IN RECENT
MONTHS,  SEVERAL  ECONOMIES  IN  ASIA, INCLUDING HONG KONG, HAVE BEEN NEGATIVELY
AFFECTED  BY  THE  OUTBREAK  OF SEVERE ACUTE RESPIRATORY SYNDROME, OR SARS. Some
industries  in  Hong  Kong have been hit hard by the SARS outbreak. The dramatic
decline  in  the business is expected to have negative effects on the economy of
Hong  Kong  for  2003. The Government of Hong Kong and business communities have
taken  various  measures  to stimulate the economic recovery of Hong Kong. While
the  ultimate  impact  of  SARS  is  unclear  at this time, the effects of these
measures  are  crucial  to  Hong  Kong's future financial condition and economic
developments,  which would in turn affect our financial condition and results of
operations.

CHANGES  IN  THE EXPORT REGULATION OF ENCRYPTION-BASED TECHNOLOGIES MAY RESTRICT
OUR  ABILITY TO SELL OR LICENSE OUR PRODUCTS. Our products are subject to export
controls  under  Canadian  and  U.S.  laws  and  regulations.  These  laws  and
regulations  may  be  revised  from time to time in ways that may materially and
adversely  affect  our  ability  to sell our products abroad or to make products
available  for  sale  or license via international computer networks such as the
Internet,  although  pursuant  to an international treaty, a number of countries
have  relaxed,  or  are  in  the  process  of  relaxing,  their  export rules as
applicable  to products of the type licensed by us. Canadian and U.S. government
controls  on  the  export of encryption technologies which we license from third
parties  and  which are embedded in our products may, if subject to revision, be
amended  and subsequently restrict our ability to freely export our products. As
a result, foreign competitors subject to less stringent export controls on their
products  may  be  able  to  compete  more effectively than we can in the global
information  and  computer  security  market.

OUR  ARTICLES  OF  INCORPORATION  AUTHORIZE  US  TO ISSUE AN UNLIMITED NUMBER OF
COMMON  SHARES, WHICH COULD RESULT IN DILUTION TO OUR SHAREHOLDERS. Shareholders
may  experience  dilution  because our articles of incorporation authorize us to
issue  an  unlimited  number  of  common  shares,  subject  to regulatory and/or
shareholder  approval.  Our  shareholders  have  no right to purchase additional
common  shares  when  we issue new shares. As of June 23, 2003, we had 9,212,308
common  shares  issued  and  outstanding.

In  addition, our ability to issue an unlimited number of common shares may have
the  effect  of  delaying, deferring or preventing a takeover attempt by a third
party  attempting  to  acquire  control  of  us.

WE  HAVE  LIMITED FINANCIAL RESOURCES. Our ability to continue operations during
the  next  fiscal  year  may  be  dependent  on our ability to obtain additional
financing.  Although  we  have made progress in developing our products and have
completed  initial  consumer  deployments,  our  revenue  from operations is not
sufficient  to  cover  our  operating  expenses at present and is unlikely to be
sufficient  within  fiscal  2003.  We  have obtained funding for operations from
private equity placements in the past, raising approximately $63,368,000 through
selling a total of 9,211,132 common shares, but there is no assurance we will be
able  to do so again in the near future despite the progress of the business. As
well,  the  terms  of  new  capital,  if  any,  may  materially  dilute existing
shareholders.  Our  failure  to  either raise capital when needed or to generate
revenues  would  leave  us with insufficient resources to continue our business.

IF OUR COMMON SHARES SHOULD BECOME INELIGIBLE FOR CONTINUED QUOTATION ON THE OTC
BB  OR  A PUBLIC TRADING MARKET DOES NOT CONTINUE FOR ANY REASON, HOLDERS OF OUR
COMMON SHARES MAY HAVE DIFFICULTY SELLING THEIR SHARES. Our common shares became
ineligible  for  continued  quotation  on the NASDAQ SmallCap Market and are now
trading  on the Over the Counter Bulletin Board; therefore holders of our common
shares  will have difficulty selling their shares. Our common shares were quoted
on  the  NASDAQ  SmallCap  Market  from  June  1995  through  late  April  2003.

OUR COMMON SHARES MAY CONTINUE TO BE PENNY STOCK, WHICH MAY ADVERSELY AFFECT THE
LIQUIDITY  OF  OUR  COMMON  SHARES.  The  United  States Securities and Exchange
Commission  has  adopted  regulations that define a penny stock to be any equity
security  that has a market price, as defined in those regulations, of less than
U.S.  $5.00  per  share,  subject  to  certain exceptions. Our common shares are
currently  penny  stock.

Generally,  for  any  transaction  involving  a  penny stock, a broker-dealer is
required to deliver, prior to the transaction, a disclosure schedule relating to
the penny stock market as well as disclosure concerning, among other things, the
commissions  payable,  current  quotations for the securities and information on
the  limited  market  in  penny  stocks.



The  liquidity  of our common shares may be materially and adversely affected if
our  common  shares  continue  to  be  penny  stock  due  to  the administration
requirements  imposed  by  these  rules.

IT  MAY BE DIFFICULT FOR OUR SHAREHOLDERS TO ENFORCE CIVIL LIABILITIES UNDER THE
U.S.  FEDERAL  SECURITIES  LAWS  BECAUSE  WE  ARE INCORPORATED IN CANADA. We are
incorporated  under Canadian law and the majority of our directors and executive
officers  are  Canadian citizens or residents. All, or a substantial portion, of
these  persons'  assets  and substantially all of our assets are located outside
the  U.S. As a result, it may not be possible for investors to effect service of
process  within  the U.S. upon those persons or Diversinet or to enforce against
them  judgments  of  U.S.  courts  predicated  upon civil liabilities under U.S.
federal  or  state  securities  laws.  Also,  there  is  uncertainty  as  to the
enforceability  in  Canada, in original actions or in actions for enforcement of
judgments  of the U.S. courts, of civil liabilities predicated upon U.S. federal
or  state  securities  laws.

WE  MAY  BE  TREATED  AS  A PASSIVE FOREIGN INVESTMENT COMPANY, WHICH WOULD HAVE
ADVERSE  TAX  CONSEQUENCES  FOR  OUR  U.S.  SHAREHOLDERS. We may be treated as a
passive  foreign  investment company, or a PFIC. While we do not believe that we
should  be  treated  as  a  PFIC,  whether  we  are treated as a PFIC depends on
questions  of  fact  concerning  our assets and revenues. Accordingly, we cannot
assure  you that we will not be treated as a PFIC. If we were to be treated as a
PFIC,  there  could  be material adverse tax consequences to U.S. holders of our
common  shares. See "United States Federal Income Tax Consequences" beginning on
page  23.



                                 USE OF PROCEEDS

We will not receive any proceeds when the selling shareholders sell their common
shares.  The  U.S.  $851,000  in  gross  proceeds  that  we may receive upon the
exercise  of  720,000 warrants will be used for continued sales efforts, general
operations  and  general working capital purposes. We will pay all costs of this
prospectus.

                                 DIVIDEND POLICY

We  have  not  paid  any  cash dividends on our common shares to date and do not
anticipate  paying  cash  dividends  in  the  foreseeable  future.

                             SELECTED FINANCIAL DATA

Our  selected  financial data for the six-month periods ended April 30, 2003 and
2002,  and  the  fiscal years ended October 31, 2002, 2001, 2000, 1999, and 1998
are derived from our financial statements and should be read in conjunction with
our  consolidated financial statements and the accompanying notes. Our financial
statements  are  expressed  in  Canadian  dollars.  All  financial  information
contained  in  the  prospectus  is  presented  in  Canadian dollars except where
otherwise  indicated.  On  January  28, 2003, the Company implemented a 1 for 10
reverse  stock  split  that  was  approved  by its shareholders at the Company's
Annual  and  Special Meeting of Shareholders on January 22, 2003. The share data
has  been  adjusted  for  this  reverse  stock  split.

Our  financial  statements  have been prepared in accordance with Canadian GAAP.
These  principles  conform  in  all  material  respects with U.S. GAAP except as
described  in  Note  15  to  our  2002  consolidated  financial  statements.

   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
                                   OPERATIONS

Our  financial  statements  have been prepared in accordance with Canadian GAAP.
These  principles  conform  in  all  material  respects with U.S. GAAP except as
described in Note 15 to our 2002 consolidated financial statements.

CRITICAL  ACCOUNTING  POLICIES

The  nature  of our business is not highly complex, as we operate in one primary
business.  We  develop, market and sell wireless security software solutions. We
also  perform  professional  services  to  install,  support  and  integrate our
solutions  with  other  applications.  We  operate  globally  in  a  functional
organization.  We  do  not  have  any  off-balance  sheet  financing, other than
operating  leases  entered  into in the normal course of business, and we do not
actively engage in derivative or hedging transactions. In 2002, our most complex
accounting  judgments  were  made  in the areas of software revenue recognition.
Software  revenue  recognition is expected to continue to be an on-going element
of  our  accounting  processes  and  judgments.

SOFTWARE  REVENUE  RECOGNITION

We  derive  our revenue primarily from two sources: sales of products, including
hardware and software licenses, and services, including maintenance, support and
professional  services.  Significant  management judgments and estimates must be
made and used in connection with the revenue recognized in any reporting period.
Material  differences  may  affect  the amount and timing of our revenue for any
period  if  our  management  made  different  judgments.

With  respect  to  software  revenue  recognition,  we  recognize  revenues  in
accordance  with  the  provisions  of the American Institute of Certified Public
Accountants'  Statement of Position No. 97-2, "Software Revenue Recognition" and
SOP No. 98-9, "Modifications of SOP No. 97-2, Software Revenue Recognition, with
Respect  to  Certain  Transactions".

For  all  sales,  we  use  a binding contract, purchase order or another form of
documented  agreement  as evidence of an arrangement with the customer. Revenues
from  software  license  agreements  are  recognized upon receipt of an executed
license  agreement  and  shipment  of  the software, if there are no significant
remaining  vendor  obligations,  collection  of  the  receivable is probable and
payment  is  due  in  accordance  with  our  normal  payment  terms.

We  consider  delivery  to  occur when we ship the product, so long as title and
risk  of  loss  have  passed  to  the  customer.

At  the  time  of  a  transaction, we assess whether the sale amount is fixed or
determinable  and whether collection is probable. If we determine the fee is not
fixed  or determinable, we recognize revenue when payment becomes due. We assess
collectibility  based  on a number of factors, including the creditworthiness of
the  customer.  If  we  determine that collectibility is not probable, we do not
record  revenue  until  such time when collectibility becomes probable, which is
generally  upon  the  receipt  of  cash.

When  arrangements  contain  multiple  elements  and  vendor  specific objective
evidence  ("VSOE")  of  fair  value  exists  for  all  undelivered  elements, we
recognize  revenue  for  the  delivered  elements using the residual method. Our
determination of fair value of each of the undelivered elements in multi-element
arrangements is based on VSOE of fair value. VSOE of fair value for each element
is  either  the  price  charged  when the same element is sold separately or the
price  established by management, having the relevant authority to do so, for an
element  not  yet sold separately. For arrangements containing multiple elements
wherein  VSOE of fair value does not exist for all undelivered elements, revenue
for  the delivered and undelivered elements is deferred until VSOE of fair value
exists  or  all  elements  have  been  delivered.



Maintenance  service  revenue,  whether sold separately or as part of a multiple
element  arrangement,  is  deferred  and recognized ratably over the term of the
maintenance contract, generally twelve months. Revenue allocated to professional
service  elements  is  recognized  as  the  services  are  performed.

Due  to  the  complexity of some software license agreements, we routinely apply
judgment  to  the  application  of  software  revenue  recognition  accounting
principles  to  specific agreements and transactions. Different judgments and/or
different  contract  structures  could  have  led  to  different  accounting
conclusions,  which  could  have had a material effect on our reported quarterly
earnings.

CAPITAL  ASSETS

We  record  our capital assets at their cost less accumulated depreciation. On a
periodic  basis,  management  reviews  the  carrying  values of these assets and
compares  it to their estimated net recoverable amount. The determination of net
recoverable  amount  necessitates various assumptions, many of which are forward
looking  and  which  are based on management's best estimate of future revenues,
expenses  and  cash  flows.  To  the  extent  that  actual financial performance
adversely differs from the results projected by these assumptions, an impairment
charge  in  the  value  of  these  assets  would  be  necessary.

RESULTS  OF  OPERATIONS

SIX MONTHS ENDED APRIL 30, 2003 COMPARED TO SIX MONTHS ENDED APRIL 30, 2002

We  reported  a  similar net loss of $2,084,000 for the three months ended April
30,  2003  compared  to  a  net  loss  of  $2,063,000 in the prior year's second
quarter.  The  net  loss  was $3,198,000 for the six months ended April 30, 2003
compared  to  a net loss of $3,788,000 in the same period in fiscal 2002. During
the  quarter  we  increased  our  depreciation  and  amortization  of  leasehold
improvements  by  $231,000  in  anticipation  of  our  subleasing of part of our
Toronto  office  space,  effective  July  1, 2003. The decreased net loss in the
first  six  months  of  2003  is  attributable  to our continued efforts in cost
control  and  in  part  to  the  acquisition  of  DSS effective January 2, 2003.

For  the  three  months  ended April 30, 2003, we reported revenue of $2,649,000
compared  to  revenue  of  $311,000  for  the  quarter ended April 30, 2002. The
current  period  revenue is made up of DSS revenues of $2,619,000 and Diversinet
revenues  of $30,000. While we signed a U.S. $200,000 licence deal in the second
quarter,  we will be recognising the revenue upon confirmation of receipt of the
payment.

Cost  of  sales  for  the  three  months  ended  April  30,  2003 was $2,253,000
(representing  a  gross  margin of 14% on DSS revenues) compared with $0 for the
quarter  ended  April 30, 2002. Cost of sales for the six months ended April 30,
2003  was  $3,039,000  (representing  a  gross  margin  of  14% on DSS revenues)
compared  with  $0  for  the  six months ended April 30, 2002. The cost of sales
represents  the  direct  costs  associated  for  DSS  completing  the consulting
services  revenue.  As  we  integrate  DSS and Diversinet and start to focus DSS
towards wireless application consulting, we expect that the gross margins on DSS
revenues  will  improve.

Research  and  development  expenses  decreased  to $532,000 in the three months
ended  April  30,  2003  from  $761,000 in the three months ended April 30, 2002
resulting  primarily  as a result of continued efforts to reduce costs. Research
and development expenses decreased to $970,000 in the six months ended April 30,
2003  from  $1,409,000  in  same  period  of  fiscal  2002.

Sales  and marketing expenses were $382,000 in the second quarter of fiscal 2003
compared  to  $476,000 in the second quarter of fiscal 2002. Sales and marketing
expenses  were  $781,000  in  the  first  six  months of fiscal 2003 compared to
$908,000  in  the  same  period of fiscal 2002. The decrease is due in part to a
reduction in travel costs and license fees. During the six months of fiscal 2003
we  expanded  the  sales  team adding experienced sales people in Hong Kong, the
U.S.  and  Canada.  We  believe  that selective additions to the sales team will
benefit  the  Company  through  increased  revenues in the short to medium term.

General  and  administrative  expenses were $1,227,000 for the second quarter of
2003  compared to $1,056,000 incurred during the second quarter of 2002. Foreign
exchange  gains  were $10,000 for the three months compared to losses of $13,000
for  the  respective  period  in  2002. General and administrative expenses were
$1,839,000  for  the  first  six  months of 2003 compared to $1,792,000 incurred
during  the  first  two quarters of 2002. Overall Diversinet G&A costs have been
reduced  from  last year, however with the acquisition of DSS, the additional of
the DSS infrastructure has caused the overall G&A to increase modestly.



Depreciation  and  amortization  expense  in  the  second quarter of fiscal 2003
increased to $365,000 from $146,000 in the second quarter of fiscal 2002. During
the quarter the Company increased its depreciation for leasehold improvements in
anticipation  of  our subleasing of certain of its office space in Toronto to be
effective  July  1, 2003. Depreciation and amortization expense in the first two
quarters  of fiscal 2003 increased to $503,000 from $267,000 for the same period
of  fiscal  2002.

LIQUIDITY  AND  CAPITAL  RESOURCES

SIX MONTHS ENDED APRIL 30, 2003 COMPARED TO SIX MONTHS ENDED APRIL 30, 2002

We  believe  that our cash and cash equivalents as at April 30, 2003 of $843,000
and  the  additional  amounts  from the financing will be sufficient to meet our
short-term working capital requirements for the remainder of the fiscal year and
into  the 2004 fiscal year. If necessary, we plan to raise additional amounts to
meet  our  working  capital  requirements  through private or public financings,
strategic  relationships  or other arrangements. However, additional funding may
not  be  available  on  terms  attractive  to  us,  or  at all. If we enter into
strategic  relationships  to  raise  additional  funds,  we  may  be required to
relinquish  rights  to  certain of our technologies. Our failure to either raise
capital  when  needed  or  to generate revenues would leave us with insufficient
resources  to  continue  our  business.

With  the  completion  of our recent financing after the quarter end, we believe
that  our  cash  and  cash  equivalents as at April 30, 2003 of $843,000 and the
additional  amounts from the financing will be sufficient to meet our short-term
working  capital  requirements for the remainder of the fiscal year and into the
2004  fiscal  year.

Cash  used  in operating activities was $795,000 in the three months ended April
30,  2003, a decline of 64% from the amount used in the same period of the prior
year.  Cash used during the quarter was comprised of the net loss of $2,084,000,

decrease  in prepaid expenses of $147,000. Cash used in operating activities was
$2,220,000  in the quarter ended April 30, 2002, attributable to the net loss of
$2,063,000  less  net  depreciation and amortization of $146,000. Other non-cash

the  promissory  notes  payable  of  $82,000,  repayment  of  the  $380,000 bank
indebtedness  and  $8,000  spent  on share consolidation costs. Cash provided by
financing  activities  in  the  quarter ended April 30, 2002, was $4,774,000. In
April  2002 we completed the issue and sale of 5,186,708 units in our capital at
U.S.  $0.60  per  unit  for  gross  proceeds  of  U.S. $3,112,022. Each unit was
comprised  of  one  common share and three-quarters of one common share purchase

                              PLAN OF DISTRIBUTION

We  are  registering  the  common shares offered hereby on behalf of the selling
shareholders.  As used herein, "selling shareholders" includes donees, pledgees,
transferees  or  other  successors-in-interest selling shares received after the
date  of  this  prospectus  from  a named selling shareholder as a gift, pledge,
partnership  distribution  or  other  transfer.  All costs, expenses and fees in
connection  with  the registration of the shares offered by this prospectus will
be  borne  by  the Company, other than brokerage commissions and similar selling
expenses,  if  any, attributable to the sale of shares offered hereby which will
be  borne by the selling shareholders. Sales of the shares offered hereby may be
effected  by  selling  shareholders  from  time  to time in one or more types of
transactions  (which  may  include  block  transactions) on the Over the Counter
Bulletin  Board  at prevailing market prices, in the over-the-counter market, in
negotiated  transactions,  through  publicly or privately negotiated put or call
options  transactions relating to the shares offered hereby, through short sales
of the shares offered hereby (including the closing of any open short position),
or  a  combination  of  such methods of sale, at market prices prevailing at the
time  of sale, or at negotiated prices. Such transactions may or may not involve
brokers  or dealers. The selling shareholders have advised us that they have not
entered  into  any  agreements,  understandings  or  arrangements  with  any
underwriters  or  broker-dealers  regarding the sale of their securities, nor is
there  an  underwriter  or  coordinating  broker  acting  in connection with the
proposed sale of the shares offered hereby by the selling shareholders.

The  selling shareholders may enter into hedging transactions with regard to the
shares  offered hereby. In connection with such transactions the counter parties
to  such  transactions may engage in short sales of the shares offered hereby or
of  securities convertible into or exchangeable for such shares in the course of
hedging  positions  they  assume  with  selling  shareholders.  The  selling
shareholders  may  also enter into other transactions which require the delivery
of  the shares offered by this prospectus, which shares such counter parties may
resell pursuant to this prospectus (as amended or supplemented, if necessary, to
reflect  such  transaction).

The  selling  shareholders  may  effect these transactions by selling the shares
offered hereby directly to purchasers or to or through broker-dealers, which may
act as agents or principals. Such broker-dealers may receive compensation in the
form  of  discounts,  concessions  or  commissions from the selling shareholders
and/or  the purchasers of the shares offered hereby for whom such broker-dealers
may act as agents or to whom they sell as principal, or both (which compensation
as  to  a  particular  broker-dealer  might  be in excess of customary brokerage
commissions).

The  selling shareholders and any broker-dealers that act in connection with the
sale  of  the  shares  offered  herein  might may be deemed to be "underwriters"
within  the  meaning of Section 2(11) of the Securities Act, and any commissions
received  by  such  broker-dealers  and  any  profit on the resale of the shares
offered  herein  sold  by  them while acting as principals might be deemed to be
underwriting  discounts  or commissions under the Securities Act. We have agreed
to  indemnify  each  selling  shareholder against certain liabilities, including
liabilities arising under the Securities Act. The selling shareholders may agree
to  indemnify  any  agent,  dealer  or  broker-dealer  that  participates  in
transactions  involving  sales  of  the  shares  offered  hereby against certain
liabilities, including liabilities arising under the Securities Act.

Because  selling  shareholders  may  be  deemed  to be "underwriters" within the
meaning of Section 2(11) of the Securities Act, the selling shareholders will be
subject  to  the prospectus delivery requirements of the Securities Act. We have
informed  the  selling  shareholders  that  the  anti-manipulative provisions of
Regulation  M promulgated under the Exchange Act may apply to their sales in the
market.



Selling  shareholders  also  may  resell  all or a portion of the shares offered
hereby  in  open  market  transactions  in  reliance  upon  Rule  144  under the
Securities  Act, provided they meet the criteria and conform to the requirements
of  Rule  144  or  another  exemption  under  the  Securities  Act.

Upon  our  being notified by a selling shareholder that any material arrangement
has been entered into with a broker-dealer for the sale of shares offered hereby
through  a  block  trade,  special  offering, exchange distribution or secondary
distribution  or  a  purchase  by  a  broker  or  dealer,  a  supplement to this
prospectus  will  be  filed,  if  required,  pursuant  to  Rule 424(b) under the
Securities  Act,  disclosing:

     -    the  name  of  each  such selling shareholder and of the participating
          broker-dealer(s);
     -    the  number  of  shares  involved;
     -    the  initial  price  at  which  such  shares  were  sold;
     -    the  commissions  paid  or  discounts  or  concessions allowed to such
          broker-dealer(s),  where  applicable;
     -    that such broker-dealer(s) did not conduct any investigation to verify
          the  information  set  out  or  incorporated  by  reference  in  this
          prospectus;  and
     -    other  facts  material  to  the  transaction.

We  will  pay  all of the costs of qualifying these securities under federal and
state  securities laws, including legal and accounting fees, as well as printing
and  other  related  costs.

                        DESCRIPTION OF PRIVATE PLACEMENTS

2003  PRIVATE  PLACEMENT
Issuance  of  5,000,000  common shares for gross proceeds of U.S. $3,100,000. On
June  23, 2003, we completed a private placement of 5,000,000 common shares at a
price of U.S. $0.62 per common share for gross proceeds of U.S. $3,100,000. This
transaction  was  effected as a private placement in accordance with Rule 506 of
Regulation  D  promulgated under the Securities Act of 1933, as amended. We will
use  the  net  proceeds  of that private placement for ongoing sales operations,
working  capital  purposes,  to continue our research and development activities
and  for  general  corporate  purposes.

Sunrise  Securities  Corp.,  as Placement Agent, exercised its option to receive
500,000  common  shares  in  lieu  of  its  U.S.  $310,000  fee from the Private
Placement.  Sunrise  also  received  40,000  common  shares  in lieu of its U.S.
S24,000  retainer fee to act as Placement Agent. Further compensation was issued
as  a  three-year  broker warrant terminating on June 20, 2006 to purchase up to
500,000  common  shares  of  the  Corporation  at  U.S.  $0.62  per  share.

We  agreed  to  file  the  registration statement to register the shares and the
shares  underlying the warrants issued pursuant to this private placement within
30  days  of  the  closing  of  the  private  placement.

PUBLIC RELATIONS RETAINER AGREEMENT
Issuance  of  200,000  common  shares and 100,000 common share purchase warrants
issuable  upon  the  exercise  of  warrants.
On  May  14,  2003,  we entered into the agreement with Sunrise Financial Group,
Inc.  to provide public relations services. In consideration for the services to
be  rendered  in  accordance  with the agreement, we issued a three-year warrant
terminating  on  May  12, 2006 to purchase up to 100,000 of our common shares at
U.S.  $0.60  per share and 200,000 common shares, being 16,667 common shares per
month  for  12  months  in  regards  to the compensation payable by us for these

Issuance of 250,000 common shares.
On May 14, 2003, we entered into a business development agreement with iSimplifi
LLC  ("iSimplifi")  to  provide business development services. This agreement is
subject  to  certain  milestones  that  if not met may allow us to terminate the
retainer portion of the agreement and /or the entire agreement. In consideration
for  the  services  to  be  rendered  by  iSimplifi,  we will pay to iSimplifi a
retainer equal to U.S. $25,000 per month, which at our discretion may be paid as
follows:  (i)  U.S. $25,000 per month in cash, or (ii) U.S. $25,000 per month by
the  issuance of 41,667 common shares per month, or (iii) U.S. $20,000 per month
in  cash  and  issuance of 8,333 common shares per month. We have elected to pay
iSimplifi  the  first  six  months  by  way  of  250,000  common  shares.



ACQUISITION  WARRANTS
Issuance  of  120,000  common  shares  purchase  warrants.
In  January  2003,  we  acquired  100% of the outstanding shares of DSS Software
Technologies,  a  consulting services provider. The aggregate purchase price was
$2,009,034  consisting  of  $473,070  (U.S.  $300,000)  in  cash, $946,140 (U.S.
$600,000)  of promissory note payable in instalments of U.S. $300,000 on January
2, 2004 and U.S. $300,000 on January 2, 2005 and 120,000 share purchase warrants
with  a fair value of $589,824 (U.S. $374,040). The share purchase warrants vest
equally  on January 2, 2003, 2004 and 2005 and are exercisable at U.S. $3.75 per
share  for  five  years.  Additional  future cash consideration in the amount of
$1,892,280  (U.S. $1,200,000) is payable based on the achievement of certain net
income  targets  over  the  next  three  years  and  will  be  recorded when the
contingency  has  been  met.

ADVISORY  BOARD  CONSULTANT  AGREEMENT
Issuance  of 50,000 common share purchase warrants issuable upon the exercise of
warrants.
On July 1, 2003, we entered into the agreement with Good Harbor Consulting, LLC.
to provide advisory board consulting services. In consideration for the services
to  be rendered in accordance with the agreement, we issued a three-year warrant
terminating  on  June  30, 2006 to purchase up to 50,000 of our common shares at
U.S.  $0.62  per  share  in  regards to the compensation payable by us for these
services.

                  UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

The  following  is  a  discussion  of  material United States Federal income tax
consequences  generally  applicable  to  a U.S. Holder (as defined below) of our
common shares. This discussion does not address all potentially relevant Federal
income  tax  matters  and  it  does not address consequences peculiar to persons
subject  to  special provisions of Federal income tax law, such as, for example,
tax-exempt  organizations,  qualified  retirement  plans,  persons  subject  to
alternative  minimum  tax,  financial  institutions,  insurance  companies, real
estate  investment  trusts,  regulated  investment  companies,  broker-dealers,
non-resident  alien  individuals  or foreign corporations whose ownership of our
common  shares  is  not  effectively  connected  with  the conduct of a trade or
business in the United States and shareholders who acquired their shares through
the  exercise  of  employee  share  options  or  otherwise  as  compensation. In
addition,  this discussion only applies to common shares held by U.S. Holders as
capital  assets  within the meaning of Section 1221 of the Internal Revenue Code
of  1986,  as  amended,  and  does  not  cover  any  state, local or foreign tax
consequences.

The  following  discussion  is  based  upon the sections of the Internal Revenue
Code,  Treasury  Regulations,  published  Internal  Revenue  Service  rulings,
published  administrative  positions  of  the Internal Revenue Service and court
decisions that are currently applicable, any or all of which could be materially
and  adversely  changed,  possibly  on  a  retroactive  basis,  at any time. The
following  discussion is for general information only and is not intended to be,
nor  should  it  be  construed  to  be,  legal  or  tax  advice to any holder or
prospective  holder  of  our common shares and no opinion or representation with
respect  to the United States Federal income tax consequences to any such holder
or  prospective  holder is made. Accordingly, holders and prospective holders of
our  common  shares  should  consult  their  own tax advisors about the federal,
state,  local,  and foreign tax consequences of purchasing, owning and disposing
of  our  common  shares.

U.S.  HOLDERS
As used herein, a "U.S. Holder" includes any person, with the exception of those
subject  to  special  provisions of Federal income tax law, who holds our common
shares  who  is  a  citizen  or  resident of the United States, a partnership or
corporation organized under the laws of the United States, an estate, the income
of  which  is  subject to United States federal income tax without regard to its
source  and  a  trust  if  a  United  States  court  is able to exercise primary
supervision  over  administration  of  the  trust  and one or more United States
persons  have  authority to control all substantial decisions of the trust or if
the  trust was in existence on August 20, 1996 and has elected to continue to be
treated  as  a  United  States  person,  and  any  other  person or entity whose
ownership  of  our  common shares is effectively connected with the conduct of a
trade  or  business  in  the  United  States.

DISTRIBUTIONS  ON  OUR  COMMON  SHARES
U.S. Holders receiving dividend distributions (including constructive dividends)
with  respect  to  our common shares are required to include in gross income for
United States Federal income tax purposes the gross amount of such distributions
to  the extent that we have current or accumulated earnings and profits, without
reduction  for  any  Canadian  income tax withheld from such distributions. Such
Canadian  tax  withheld may be credited, subject to certain limitations, against
the  U.S. Holder's United States Federal Income tax liability or, alternatively,
may  be



deducted  in computing the U.S. Holder's United States Federal taxable income by
those  who  itemize  deductions  (see  more  detailed discussion at "Foreign Tax
Credit"  below).  To  the  extent  that  distributions  exceed  our  current  or
accumulated  earnings  and  profits,  they  will be treated first as a return of
capital  up  to  the  U.S.  Holder's  adjusted  basis  in  the common shares and
thereafter  as gain from the sale or exchange of the common shares. Preferential
tax rates for long-term capital gains are applicable to an U.S. Holder, which is
an  individual,  estate  or trust. There are currently no preferential tax rates
for  long-term  capital  gains  for  an  U.S.  Holder,  which  is a corporation.
Dividends  paid in Canadian dollars will be included in income in an U.S. dollar
amount  based  on  the  exchange rate at the time of their receipt. U.S. Holders
should  consult  their  own  tax advisors regarding the treatment of any foreign
currency  gain  or loss on any Canadian dollars received as a dividend which are
converted  into  U.S.  dollars  on  a  date  subsequent  to  receipt.

Dividends  paid  on  our  common  shares  will not generally be eligible for the
dividends  received  deduction provided to corporations receiving dividends from
certain  United  States  corporations. A U.S. Holder which is a corporation may,
under certain circumstances, be entitled to a 70% deduction of the United States
source  portion  of  dividends received from us (unless we qualify as a "foreign
personal  holding company" or a "passive foreign investment company", as defined
below)  if  such U.S. Holder owns shares representing at least 10% of the voting
power  and value of Diversinet. The availability of this deduction is subject to
several  complex  limitations,  which  are  beyond the scope of this discussion.

FOREIGN  TAX  CREDIT
A  U.S. Holder who pays (or has withheld from distributions) Canadian income tax
with  respect  to  the  ownership  of  our common shares may be entitled, at the
option  of  the  U.S.  Holder,  to  either  a deduction or a tax credit for such
foreign tax paid or withheld. Generally, it will be more advantageous to claim a
credit  because  a  credit  reduces  United  States  Federal  income  taxes on a
dollar-for-dollar  basis, while a deduction merely reduces the taxpayer's income
subject  to  tax.  This  election  is made on an annual basis and applies to all
foreign income taxes (or taxes in lieu of income tax) paid by (or withheld from)
the  U.S.  Holder during the year. There are significant and complex limitations
which apply to the credit, among which is the general limitation that the credit
cannot  exceed  the proportionate share of the U.S. Holders United States income
tax  liability  that the U.S. Holder's foreign source income bears to his/her or
its  worldwide  taxable  income.

In the determination of the application of this limitation, the various items of
income  and  deduction  must  be  classified  into foreign and domestic sources.
Complex  rules govern this classification process. There are further limitations
on  the foreign tax credit for certain types of income such as "passive income",
"high withholding tax interest", "financial services income", "shipping income",
and  certain other classifications of income. In certain circumstances, recently
enacted  legislation and other guidance issued by the United States Treasury may
deny  a  United  States  holder  foreign  tax  credits  (and  instead  may allow
deductions)  for foreign taxes imposed on a dividend if the United States holder
(i)  has  not  held  the common shares for at least 16 days in the 30-day period
beginning  15 days before the ex-dividend date, during which it is not protected
from  risk of loss; (ii) is obligated to make payments related to the dividends;
or  (iii)  holds  the  common  shares in arrangements in which the United States
holder's  expected  economic  profit,  after  non-US  taxes,  is  insubstantial.

The  availability  of  the  foreign  tax  credit  and  the  application  of  the
limitations  on the credit are fact specific and holders and prospective holders
of  our  common  shares  should  consult  their own tax advisors regarding their
individual  circumstances.

DISPOSITION  OF  OUR  COMMON  SHARES
A  U.S.  Holder  will  recognize gain or loss upon the sale of our common shares
equal  to  the  difference, if any, between (i) the amount of cash plus the fair
market  value  of any property received, and (ii) the shareholder's tax basis in
the  our  common shares. Any gain recognized on the sale or other disposition of
common  shares  will generally be U.S. source income. Any loss recognized on the
sale  or  other  disposition  of  common  shares  will generally be U.S. source.
However,  such  loss will be foreign source to the extent certain dividends were
received  by  the  U.S. Holder within the 24-month period proceeding the date on
which the loss was recognized. This gain or loss will be capital gain or loss if
the  common shares are capital asset in the hands of the U.S. Holder, which will
be  a  short-term  or  long-term capital gain or loss depending upon the holding
period of the U.S. Holder. Gains and losses are netted and combined according to
special  rules  in arriving at the overall capital gain or loss for a particular
tax  year.  Deductions  for  net  capital  losses  are  subject  to  significant
limitations.  For U.S. Holders who are individuals, a capital loss is deductible
only  to the extent of capital gains, plus ordinary income of up to U.S. $3,000;
any  unused  portion  of such net capital loss may be carried over to be used in
later  tax  years  until  such  net  capital loss is thereby exhausted. For U.S.
Holders  which are corporations (other than corporations subject to Subchapter S
of  the  Internal Revenue Code), any unused net capital loss may be carried back
three years from the loss year and carried forward five years from the loss year
to  be  offset  against  capital  gains  until  such net capital loss is thereby



exhausted.  If  the  amount realized on a sale or exchange is not denominated in
U.S.  dollars,  the  amount  realized  will  be  equal  to the U.S. dollar value
thereof,  determined  at  the  spot  rate  on  the date of the sale or exchange.

OTHER  CONSIDERATIONS
In  the  following three circumstances, the above sections of the discussion may
not  describe  the  United States Federal income tax consequences resulting from
the  holding  and  disposition  of our common shares. Based on (a) the number of
shareholders  of  our  common shares, and (b) our shareholder profile, we do not
believe that we are either a "Foreign Personal Holding Company" or a "Controlled
Foreign  Corporation".  However,  we  do  not  believe  that we are likely to be
treated  as  a  "Passive Foreign Investment Company" for the taxable years 1999,
2000  and  2001.

FOREIGN  PERSONAL  HOLDING  COMPANY
If,  at  any  time  during  a  taxable year, more than 50% of the total combined
voting power or the total value of our outstanding shares are owned, actually or
constructively,  by  five  or fewer individuals who are citizens or residents of
the  United States and 60% or more of our gross income for such year was derived
from  certain  passive  sources  (e.g.  from  dividends  received from unrelated
persons),  we  would be treated as a "foreign personal holding company." In that
event,  U.S. Holders that hold our common shares would be required to include in
gross  income  for  such  year their allowable portions of such foreign personal
holding  company  income  to  the extent that we do not actually distribute such
income.

CONTROLLED  FOREIGN  CORPORATION
If more than 50% of the voting power of all classes of shares or the total value
of  our  shares  is owned, directly or indirectly, by U.S. shareholders, each of
whom  own  10%  or  more of our voting shares ("U.S. Shareholders"), we could be
treated  as  a "controlled foreign corporation" (a "CFC") under SubPart F of the
Internal  Revenue  Code.  If  we  were  classified  as  a CFC and as a PFIC, CFC
treatment  would  prevail  with respect to U.S. Shareholders. CFC classification
would  affect  many  complex  results  including  the required inclusion by such
United  States  shareholders  in  income  of their pro rata share: of "SubPart F
Income"  (as  specially defined by the Internal Revenue Code) of Diversinet; and
of  our  earnings  invested in U.S. property. In addition, under Section 1248 of
the  Internal  Revenue Code, gain from the sale or exchange of our common shares
by  a  U.S.  person who is or was a United States shareholder (as defined in the
Internal  Revenue Code) at any time during the five years period ending with the
sale  or exchange is generally treated as ordinary dividend income to the extent
of  our  earnings  and  profits  attributable  to  the shares sold or exchanged.
Because  of the complexity of SubPart F, and because it is not clear that we are
a  controlled  foreign  corporation,  a  more  detailed review of these rules is
outside  of  the  scope  of  this  discussion.

PASSIVE  FOREIGN  INVESTMENT  COMPANY
As  stated  above,  we  believe that we will not be treated as a passive foreign
investment  company ("PFIC"), as defined in Section 1297 of the Internal Revenue
Code,  for  our  fiscal  years  2002  or  2003.

United  States  income tax legislation contains rules governing PFIC's, that can
have  significant  tax  effects  on  U.S. Holders of foreign corporations. These
rules  do  not  apply  to non-U.S. Holders. Section 1297 of the Internal Revenue
Code  defines  a  PFIC  as a corporation that is not formed in the United States
and,  for  any  taxable  year,  either  (i)  75%  or more of its gross income is
"passive income", which includes interest, dividends and some types of rents and
royalties  or  (ii)  the  average  percentage,  by fair market value (or, if the
company  is  a  controlled foreign corporation or makes an election, by adjusted
tax  basis),  of  its  assets  that  produce  or  are held for the production of
"passive  income"  is  50%  or  more.  Based  on  these tests we do not meet the
definition  of  a  PFIC  in  1999,  2000  or  2001.

An  U.S.  Holder  who  holds  shares in a foreign corporation during any year in
which  such  corporation  qualifies  as a PFIC is subject to U.S. Federal income
taxation  under alternative tax regimes, depending upon whether such U.S. Holder
makes  elections. The following is a discussion of these alternative tax regimes
as  applicable  to  our  U.S.  Holders.

A  U.S.  Holder  of  a  PFIC who does not make either of the elections described
below  (a "Non-electing U.S. Holder") is subject to special taxation rules under
Section  1291 of the Internal Revenue Code with respect to (i) gains realized on
the  disposition  (or  deemed  to  be realized by reason of a pledge) of his/her
common  shares  and (ii) excess



distributions  by us, defined as any distribution received by a U.S. Holder from
a  PFIC in a taxable year that is greater than 125% of the average distributions
received  by  the  U.S.  Holder  in  the  three  preceding taxable years, or, if
shorter,  the  U.S.  Holder's  holding  period  for  the  shares.

A  Non-electing U.S. Holder generally would be required to include in income pro
rata  all  gains  realized  on  the disposition of his/her common shares and all
excess  distributions over the entire holding period for the PFIC common shares.
All  gains  or  excess distributions allocated to prior years of the U.S. Holder
(other  than  years  prior  to the first taxable year of the company during such
U.S.  Holder's  holding  period and beginning after January 1, 1987 for which it
was  a  PFIC)  would  be  taxed at the highest tax rate for each such prior year
applicable to ordinary income. The Non-electing U.S. Holder also would be liable
for  interest on the foregoing tax liability for each such prior year calculated
as  if  such  liability  had  been  due  with respect to each such prior year. A
Non-electing  U.S.  Holder  that  is  not a corporation must treat this interest
charge  as "personal interest" which, as discussed above, is partially or wholly
non-deductible.  The  balance  of  the  gain  or the excess distribution will be
treated  as  ordinary income in the year of the disposition or distribution, and
no  interest  charge  will  be  incurred  with  respect  to  such  balance.

If  we  are  a PFIC for any taxable year during which a Non-electing U.S. Holder
holds  common shares, then we will continue to be treated as a PFIC with respect
to  such  common  shares,  even  if  we are no longer a PFIC as defined above. A
Non-electing  U.S.  Holder  may terminate this deemed PFIC status by electing to
recognize  a  gain  (which  will  be  taxed  under the rules discussed above for
Non-electing  U.S.  Holders)  as if such common shares had been sold on the last
day  of  the  last  taxable  year  for  which  it  was  a  PFIC.

Under  Section  1291(f)  of  the  Internal  Revenue  Code, the Department of the
Treasury  has  issued proposed regulations that would treat as taxable transfers
of  PFIC  shares  by  Non-electing U.S. Holders that are generally not otherwise
taxed,  such  as  gifts,  exchanges  pursuant  to corporate reorganizations, and
transfers at death. Special, generally adverse, rules will apply with respect to
the  common  shares  while  the  company  is  a  PFIC. For example under Section
1298(b)(6)  of  the Internal Revenue Code, a U.S. Holder who uses PFIC shares as
security for a loan (including a margin loan) will, except as may be provided in
regulations,  be  treated  as  having made a taxable disposition of such shares.

Alternatively,  if we are a PFIC, an U.S. Holder (an "Electing U.S. Holder") who
owns  common  shares  is  permitted  generally to elect out of the tax treatment
discussed  above, if an U.S. Holder makes a mark-to-market election with respect
to  common  shares. Under such election, an Electing U.S. Holder would generally
recognize  as  ordinary  income  for  each  taxable  year an amount equal to the
excess, if any, of the fair market value of common shares as of the close of the
taxable  year over the Electing U.S. Holder's adjusted tax basis in such shares.
An Electing U.S. Holder would generally be allowed an ordinary deduction (to the
extent  of  any net mark-to-market gains recognized for prior taxable years) for
the  excess,  if  any, of the adjusted tax basis of the common shares over their
fair market value as of the close of the taxable year. An Electing U.S. Holder's
adjusted  tax  basis of the common shares would generally be adjusted to reflect
the  amounts  included  or  deducted  under  the  mark-to-market  election.
Additionally,  any  gain  on  the actual sale or other disposition of the common
shares  generally  will  be  treated as ordinary income. Ordinary loss treatment
also  would  generally  apply  to  any loss realized on the actual sale or other
disposition  of the common shares to the extent that the amount of such loss did
not exceed the net mark-to-market gains previously included with respect to such
shares.  An election to mark to market would generally apply to the taxable year
made  and  all subsequent taxable years. A mark-to-market election is subject to
complex and specific rules and requirements, and U.S. Holders are strongly urged
to  consult  their  tax  advisors  concerning  such  election  if the company is
classified  as  a  PFIC.

Finally,  an  U.S.  Holder  who  elects  in  a  timely  manner  to treat us as a
"qualified  electing  fund"  (a  "QEF")  as defined in the Internal Revenue Code
would  be subject to another set of special rules different from those described
above.  Although a QEF election may be beneficial to some U.S. Holders depending
upon  their  particular  tax  situations,  it  requires  us  to make information
available  to  such  holders,  and  we  do  not  intend to make such information
available even if it is classified as a PFIC. Accordingly, the QEF election will
not  be  available  to  U.S.  Holders.

The foregoing discussion is based on existing provisions of the Internal Revenue
Code,  existing  and proposed regulations thereunder, and current administrative
ruling  and court decisions, all of which are subject to change. Any such change
could affect the validity of this discussion. In addition, the implementation of
aspects  of  the  PFIC  rules requires the issuance of regulations which in many
instances have not been promulgated and which may have retroactive effect. There
can  be  no  certainty that any of these proposed regulations will be enacted or
promulgated



and  if  so,  the  form  they will take or the effect that they may have on this
discussion.  Accordingly,  and  due  to  the  complexity of the PFIC rules, U.S.
Holders  who  are shareholders of Diversinet are strongly urged to consult their
own tax advisors concerning the impact of these rules on their investment in us.

                       ENFORCEABILITY OF CIVIL LIABILITIES

Service  of process upon us and upon our directors and officers and the Canadian
experts  named  in this prospectus, most of whom reside outside the U.S., may be
difficult  to  obtain  within the U.S. Furthermore, because substantially all of
our  assets  and  substantially  all  of  our directors and officers are located
outside  the  U.S.,  any  judgment obtained in the U.S. against us or any of our
directors and officers may not be collectible within the U.S.

All  of  the above expenses except the registration fee and placement commission
are  estimated.

ITEM  15.  INDEMNIFICATION  OF  DIRECTORS  AND  OFFICERS

Under  the  Business  Corporations  Act  (Ontario)  (the  "Act"), Diversinet may
indemnify  a present or former director or officer or a person who acts or acted
at Diversinet's request as a director or officer of another corporation of which
Diversinet  is  or  was  a  shareholder  or  creditor  and  his  heirs and legal
representatives  against  all  costs,  charges and expenses, including an amount
paid  to  settle  an action or satisfy a judgment, reasonably incurred by him in
respect  of  any civil, criminal or administrative action or proceeding to which
he  is made a party by reason of being or having been such a director or officer
if  the  director or officer acted honestly and in good faith with a view to the
best  interests  of  Diversinet and, in the case of a criminal or administrative
action  or  proceeding  that  is  enforced by a monetary penalty, had reasonable
grounds  for  believing that his conduct was lawful. Such indemnification may be
made  in  connection  with an action by or on behalf of Diversinet or such other
corporation  only  with  court  approval.  A  director or officer is entitled to
indemnification  from  Diversinet as a matter of right in respects of all costs,
charges  and  expenses reasonably incurred by him in connection with the defense
of  any  civil,  criminal or administrative proceeding to which he is a party by
reason  of  being or having been a director or officer of such corporation if he
was  substantially  successful  on  the  merits and fulfilled the conditions set
forth  above.

The  by-laws of Diversinet provide that each director, each officer, each former
director,  each former officer and each person who acts or acted at Diversinet's
request  as  a director or officer of a body corporate of which Diversinet is or
was  a shareholder or creditor, and his heirs and legal representatives shall be
indemnified and saved harmless by Diversinet from and against all costs, charges
and expenses, including without limitation, each amount paid to settle an action
or  satisfy  a  judgment,  reasonably  incurred  by him in respect of any civil,
criminal  or administrative action or proceeding to which his is made a party by
reason  or being or having been a director or officer of Diversinet or such body
corporation,  if he acted honestly and in good faith with a view to Diversinet's
best  interests  and  in  the  case  of  a  criminal or administrative action or
proceeding  that is enforced by a monetary penalty he had reasonable grounds for
believing  his  conduct  was  lawful.  In  certain  circumstances Diversinet has
provided  its  Directors  or  its  subsidiaries'  Directors  with  a  written
indemnification  confirming  the  indemnification  available  under its by-laws.

Diversinet  currently  maintains  directors'  and officers' liability insurance,
which, subject to the provisions contained in the policy, protects the directors
and  officers,  as  such,  against  all  claims  during the term of their office
provided they acted honestly and in good faith with a view to the best interests
of  Diversinet.  Such  insurance  provides  for  an aggregate of U.S. $5,000,000
annual  protection  against  liability  for  and  reimbursement of amounts paid.

Insofar  as  indemnification for liabilities arising under the Securities Act of
1933,  as amended may be permitted to directors, officers or persons controlling
the  registrant  pursuant  to  the foregoing provisions, the registrant has been
informed  that,  in  the opinion of the U.S. Securities and Exchange Commission,
such indemnification is against public policy as expressed in the Securities Act
of  1933,  as  amended  and  is  therefore  unenforceable.

ITEM  17.  UNDERTAKINGS

Paragraph  designations  correspond to designations in Regulation S-K, Item 512.

(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,  as  amended;
          (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 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,
               the changes in volume and price represent no more than 20 percent
               change  in  the maximum 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, as amended, 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)  To  file  a  post-effective amendment to the registration statement to
          include  any  financial statements required by Rule 3-19 of Regulation
          S-X  at  the  start of any delayed offering or throughout a continuous
          offering.  Financial  statements and information otherwise required by
          Section  10(a)(3) of the Act need not be furnished, provided, that the
          registrant  includes  in  the prospectus, by means of a post-effective
          amendment,  financial  statements  required pursuant to this paragraph
          (a)(4)  and  other  information  necessary  to  ensure  that all other
          information  in  the  prospectus is at least as current as the date of
          those  financial  statements.  Notwithstanding  the  foregoing,  with
          respect  to  registration  statements  on  Form  F-3, a post-effective
          amendment  need  not  be  filed  to  include  financial statements and
          information  required  by  Section 10(a)(3) of the Act or Rule 3-19 of
          Regulation  S-X  if  such  financial  statements  and  information are
          contained  in  periodic  reports  filed  with  or  furnished  to  the
          Commission  by  the registrant pursuant to Section 13 or Section 15(d)
          of  the  Securities  Exchange  Act  of  1934,  as  amended  that  are
          incorporated  by  reference  in  the  Form  F-3.

(b)  The  undersigned  registrant  hereby  undertakes  that,  for  purposes  of
     determining  any  liability  under  the Securities Act of 1933, as amended,
     each  filing of the registrant's annual report pursuant to section 13(a) of



     section 15(d) of the Securities Exchange Act of 1934, as amended (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, as
     amended)  that  is  incorporated by reference in the 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, as amended may be permitted to directors, officers and controlling
     persons  of  the  registrant,  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 expense incurred
     or  paid by a director, officer, or controlling person of the registrant in
     the  successful defense of any such 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.




                                   SIGNATURES

Pursuant  to  the  requirements  of  the Securities Act of 1933, as amended, the
registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form F-3 and has duly caused this Registration
Statement  to  be  signed  on  its  behalf  by  the  undersigned, thereunto duly
