                           PLACEMENT AGENCY AGREEMENT

                                 March 27, 2002


Allen & Company Incorporated
711 Fifth Avenue
New York, New York 10022

Gentlemen:

          Diversinet  Corp.,  a  corporation  organized  under  the  laws of the
Province  of  Ontario, Canada (the "Company") hereby confirms its agreement with
you  as  follows:

          1.  The  Offering.  The  Company is offering to persons who qualify as
              -------------
"accredited  investors,"  as  that  term  is  defined  in Regulation D under the
Securities Act of 1933 as amended (the "Act"), approximately 5,250,000 shares of
the Company's Common Stock (the "Shares") at an initial subscription price to be
determined  by  the Company and you.  The foregoing offer and sale of the Shares
is hereinafter referred to as the "Offering."  The Company has the right, in its
sole discretion, to reject or cut back any subscription or any offer to purchase
shares.

          2.  Appointment  of  Placement  Agent.  You  are  hereby appointed the
              ---------------------------------
exclusive  placement  agent  of  the  Company (the "Placement Agent") during the
Offering  Period (as defined herein) for the purpose of assisting the Company in
identifying  qualified  subscribers to purchase Shares (the "Subscribers").  The
"Offering  Period" shall commence on the date the Offering Materials (as defined
herein)  are  first  made  available  to  you  by  the  Company  for delivery in
connection  with  the  Offering  and  shall  terminate on or before the close of
business  on  the  earliest to occur of the closing of the sale of Shares or the
termination  of  this  Agreement.  You  hereby  accept  such agency and agree to
assist  the  Company  in  identifying  qualified Subscribers on a "best efforts"
basis.  Your  agency hereunder may not be terminated by the Company, except upon
termination  of  the Offering, upon the Placement Agent's failure to perform its
obligations  hereunder  in  all  material  respects,  upon the Placement Agent's
material  breach  of  any  of  its  representations  and warranties contained in
Section  7  hereof or upon gross negligence or willful misconduct on the part of
the  Placement Agent.  It is understood that the offering and sale of the Shares
is  intended  by  all parties to be exempt from the registration requirements of
the  Act  pursuant  to Section 4(2) thereof and the rules and regulations of the
Securities  and Exchange Commission thereunder, including Rule 506 of Regulation
D  (the  "Rules  and  Regulations").

          3.  Offering Materials.  The Company has prepared and delivered to the
              ------------------
Placement  Agent  a  reasonable  number  of copies of an informational packet of
materials  containing  (i)  the Annual Report for the fiscal year ending October
31,  2001  and  (ii)  other  disclosure  materials  relating  to  the  Company
(collectively,  the  "Disclosure  Documents").  The Disclosure Documents and the
Subscription  Agreements  relating  to  the  Shares  (each,  a  "Subscription
Agreement")  are  referred to herein as the "Offering Materials," except that if
the  Offering  Materials  shall  be amended, the term "Offering Materials" shall
refer  to  the  Offering  Materials  as  so  amended  from and after the time of
delivery  to  you  of  such  amendment.  The  Placement  Agent shall deliver the
Offering  Materials  to  each  Subscriber  prior  to  investment.

          4.   Closing;  Delivery;  Placement  Fees.
               ------------------------------------

               (a)  It  is anticipated that the closing of the purchase and sale
of  the  Shares to Investors may be effected at a closing (the "Closing"), which
shall  take  place  at  the  offices  of Allen & Company Incorporated, 711 Fifth
Avenue,  New  York,  New  York 10022 at 10:00 a.m. on or before April 4, 2002 on
three business days' notice or such other time, date or place as shall be agreed
upon  by  you  and  the  Company  (the  "Closing  Date").

               (b)  At  the  Closing, there shall be delivered to the Company on
behalf  of  each  applicable  Subscriber  executed  copies  of  the Subscription
Agreement  to  be  entered  into  by  the  Company and each such Subscriber (the
"Purchasers")  as of such Closing Date, and there shall also be delivered to the
Company  on  behalf  of each applicable Purchaser the proportionate share of the
purchase  price  of  the  Shares  which such Purchaser is to purchase.  Upon the
Closing,  the  Company will deliver, or cause to be delivered, to the Purchasers
certificates  representing  the  Shares  purchased  by  them.



               (c)  Simultaneous  with the Closing, as provided in paragraph (b)
above,  the  Company  shall  pay  or  cause  to be paid to the Placement Agent a
placement  fee  equal  to

               1.   $140,000  and  100,000  warrants  to  purchase shares of the
                    Company,  exercisable for a period of three years at a price
                    of  $0.72  per common share. Furthermore (and in addition to
                    the  100,000  warrants you otherwise receive pursuant to the
                    immediately  preceding  sentence)  you shall have the right,
                    subject to applicable law and regulations, to purchase up to
                    234,000  units (the "Units") consisting of one Share and 3/4
                    warrant  (all on the same terms as Subscribers purchasing in
                    the  Offering)  such  that the number of warrants associated
                    with  the  Shares purchased by you would equal up to 175,500
                    warrants (with each of such warrants exercisable at price of
                    $0.72 per share). The price of each Unit shall be $0.60, and
                    you shall have until April 30, 2002 to elect to purchase the
                    Units,  after  which  time the right to purchase the 240,000
                    Units  (and  the  associated 175,5000 warrants) shall cease.
                    The  Company  shall  cause the Shares purchased by you under
                    this  clause  (and the Shares underlying the warrants) to be
                    registered  under  the  Securities  Act  of 1933 on the same
                    basis  as  the  Units  purchased  by  Subscribers  in  the
                    Offering).

               2.   Should the Placement Agent fail to exercise its right on the
                    234,000  Units  (or  should  there  be a legal or regulatory
                    impediment  to  such  exercise),  then the Company shall, in
                    lieu  of the immediately preceding paragraph, pay the to the
                    Placement Agent a fee equal to $100,000 and 100,000 warrants
                    to  purchase shares of the Company, exercisable for a period
                    of  three  years  at  a  price  of  $0.72  per common share.

               The  Company  shall  reimburse  the  Placement  Agent  for  its
out-of-pocket  expenses  as  provided  in  Section  6(c)  hereof,  against  the
presentation  of  bills  therefor.  If  such  bills  are  not  available  for
presentation  at  the  time of the Closing, then the Company shall reimburse the
amount  of  the  Placement  Agent's  reasonable  estimate  of such out-of-pocket
expenses;  in such event, the Placement Agent shall promptly provide the Company
with  an  accounting  of  actual  expenses  when  known,  and  the parties shall
reconcile  any  amounts  still  owing  among  to  them.  Such  warrants shall be
represented by the Warrant Certificate substantially in the form attached hereto
as Exhibit A. All fees payable to the Placement Agent by the Company pursuant to
   ---------
this  Placement  Agency  Agreement  shall be unrelated to all transactions other
than  the  Offering.

          5.  Representations and Warranties of the Company.  The Company hereby
              ---------------------------------------------
confirms  for  the  benefit  of  the  Placement  Agent  the  representations and
warranties  made by it to the Subscribers in the Subscription Agreements, to the
extent  applicable,  and  hereby  further  represents  and  warrants  that  this
Agreement  has  been  duly  authorized,  executed and delivered on behalf of the
Company  and  constitutes  a  valid  and  binding  agreement  of  the  Company,
enforceable  against  the  Company  in accordance with its terms, subject to the
effect  of  any applicable bankruptcy, insolvency, reorganization, moratorium or
similar  law  affecting creditors' rights generally and to general principles of
equity  and  except  as  rights  to  indemnity  or contribution hereunder may be
limited  by  Federal  or  state  securities  laws.

          6.  Covenants  of  the Company.  The Company covenants and agrees with
              --------------------------
the  Placement  Agent  that:

               (a)  During  the  Offering  Period,  the  Company will notify the
Placement  Agent  of  any event of which it is aware as a result of which any of
the  Offering  Materials would include an untrue statement of a material fact or
omit  to  state  any  material  fact necessary to make the statements therein in
light of the circumstances under which they were made not materially misleading;
and  it  will  provide  you  with  any  amendment  or supplement to the Offering
Materials  during the Offering Period.  The Company will conduct the Offering in
compliance  with  Section  4(2) of the Act and the Rules and Regulations and all
applicable  state  securities  laws  and  regulations.

               (b)  If required by law, the Company will use its best efforts to
qualify  the  Shares for offer and sale under the Blue Sky or securities laws of
such  jurisdictions  as you may designate and to continue such qualifications in
effect  for  so long as may be required for purposes of the private placement of
the  Shares,  except  that  the  Company  shall  not  be  required in connection
therewith  or  as  a condition thereof to qualify as a foreign corporation or to
execute  a  general  consent  to  service  of process in any state or to subject
itself  to  taxation in any jurisdiction where it is not already subject to such
taxation.


                                        2

               (c)  The  Company  covenants and agrees with you that it will pay
the  reasonable  and  documented expenses and fees up to U.S. $15,000 (including
the reasonable fees and expenses of Heller Ehrman White & McAuliffe LLP, special
counsel to the Placement Agent, and blue sky fees and expenses), incurred by you
in  connection  with  (i) the preparation and delivery of the Offering Materials
delivered  to  prospective Subscribers, (ii) the furnishing of closing documents
and (iii) the qualification of the Shares for offer or sale under the securities
laws  of  such  jurisdictions  as  you  may  reasonably  designate.

               (d)  The Company agrees to cooperate with the Placement Agent and
its  special  counsel  with  respect  to  their  due  diligence  investigation.

          7.  Representations,  Warranties and Covenants of the Placement Agent.

               (d)  The  Placement  Agent  is a registered broker dealer in good

               (c)  The  Placement  Agent  shall  have performed its obligations

          9.  Conditions  of  Placement  Agent's  Performance.  The purchase and

sale of the Shares and the obligations of the Placement Agent as provided herein
shall be subject to the accuracy in all material respects, as of the date hereof
and  each  Closing  Date  (as  if  made  on and as of such Closing Date), of the

material  respects  by  the  Company  of  its  obligations hereunder, and to the

                                        3

               (b)  You  shall  have  received  a  certificate, dated as of each
Closing  Date,  of  an authorized executive officer of the Company to the effect
that:

          (i)  The  representations  and  warranties  of  the  Company  in  this
     Agreement  and  in  the Subscription Agreements are true and correct in all
     material  respects  as  if  made  on  and  as of such Closing Date; and the

     and the Subscription Agreements to be performed or satisfied at or prior to
     such  Closing  Date;  and

          (ii)  Except  as  set  forth  in  the  Offering  Materials  or  in the
     Subscription  Agreements  and  subsequent  to  the  date of the most recent

               (c)  The  Company  shall have furnished to you such certificates,

as  you  or  your  counsel  may  reasonably  request.

          10.   Indemnification.  (a)  The  Company  will  indemnify  and  hold
                ---------------
harmless  the Placement Agent, the directors and officers of the Placement Agent
and  each person, if any, who controls the Placement Agent within the meaning of
the Act against any losses, claims, damages or liabilities, joint or several, to
which the Placement Agent or any such directors, officers or controlling persons
may  become subject, under the Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon  (i)  any untrue statement or alleged untrue statement of any material fact
contained  in the Offering Materials, as of their respective dates, or arise out
of  or  are  based  upon  the  omission  or  alleged omission to state therein a
material  fact required to be stated therein or necessary to make the statements
therein  not  misleading;  or  (ii)  the Company's engagement of Allen & Company
Incorporated  as Placement Agent or any service the Placement Agent performs for
the  Company  or  on its behalf pursuant to this Agreement, except to the extent
that  any such loss, claim, damage or liability is found by a court of competent
jurisdiction  in  a  judgment  that  has  become  final (in that it is no longer
subject  to  appeal or review) to have resulted directly and primarily from such
Indemnified  Person's  gross  negligence  or  willful  misconduct.  Subject  to
subsection (c) below, the Company will reimburse the Placement Agent or any such
directors,  officers  or  controlling  persons  for  any legal or other expenses
reasonably  incurred  by  the Placement Agent or any such directors, officers or
controlling persons in connection with investigating or defending any such loss,
claim, damage, liability or action; provided, however, that the Company will not
be liable in any case to the extent that any such loss, claim, damage, liability
or  action  arises out of or is based upon an untrue statement or alleged untrue
statement  or omission or alleged omission made in the Offering Materials, as of
their  respective  dates,  in  reliance  upon  and  in  conformity  with written
information  furnished  by  and with respect to the Placement Agent specifically
for  use  in  the  preparation  thereof.  The  Company  shall not be required to
indemnify  the  Placement  Agent  or any such directors, officers or controlling
persons  for any payment made to any claimant in settlement of any suit or claim
unless  such  payment  is  approved  by the Company, which approval shall not be
unreasonably  withheld or delayed.  This indemnity agreement will be in addition
to  any liability which the Company may otherwise have, but in no event shall an
indemnified  party  receive  more  than  the  amount  of  his  claim.

          (b)  The Placement Agent will indemnify and hold harmless the Company,
its  officers  and  directors  and each person, if any, who controls the Company
within  the  meaning  of  the  Act  against  any  losses,  claims,  damages  or
liabilities,  joint  or  several,  to  which the Company, or any such directors,
officers  or  controlling  persons  may  be  or become subject, under the Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect  thereof) arise out of or are based upon any untrue statement or alleged
untrue statement of any material fact contained in the Offering Materials, as of
their  respective  dates,  or  arise  out  of  or are based upon the omission or
alleged  omission to state therein a material fact required to be stated therein
or  necessary to make the statements therein not misleading, in each case to the
extent,  but  only  to  the extent, that such untrue statement or alleged untrue
statement  or omission or alleged omission was made in the Offering Materials in
reliance  upon  and in conformity with written information furnished by and with
respect  to the Placement Agent specifically for use in the preparation thereof;
and  (subject  to  subsection  (c) below) will reimburse the Company or any such
directors,  officers  or  controlling  persons  for  any legal or other expenses
reasonably  incurred by the Company or any such director, officer or controlling
person  in  connection  with  investigating  or  defending any such loss, claim,
damage,  liability  or  actions.  The  Placement  Agent shall not be required to
indemnify the Company or any such directors, officers or controlling persons for
any  payment  made  to  any  claimant  in settlement of any suit or claim unless
payment  is  approved  by  the  Placement  Agent,  which


                                        4

approval shall not be unreasonably withheld or delayed. This indemnity agreement
will be in addition to any liability the Placement Agent may otherwise have, but
in  no  event  shall  an  indemnified  party receive more than the amount of his
claim.

          (c)  Promptly  after  receipt  by  an  indemnified  party  under
subparagraphs  10(a) or (b) of notice of the commencement of any action or other
proceeding (including governmental investigations) in respect of which indemnity
may  be sought, such indemnified party will, if a claim in respect thereof is to
be made against the indemnifying party under such subparagraphs, promptly notify
the  indemnifying party in writing of the commencement thereof; but the omission
to so notify the indemnifying party will not relieve it from any liability which
it may have to any indemnified party otherwise than under such subparagraph.  In
case  any  such  action  shall  be brought against any indemnified party, and it
shall  promptly  notify  the indemnifying party of the commencement thereof, the
indemnifying  party  will be entitled to participate in, and, to the extent that
it  may  wish,  assume and control the defense thereof with counsel chosen by it
and  after  notice  from the indemnifying party to such indemnified party of its
election  so  to  assume  and control such defense with counsel chosen by it, it
shall  bear all expenses of such defense.  Any such indemnified party shall have
the  right  to  employ separate counsel in any such action and to participate in
the  defense  thereof, but the fees and expenses of such counsel shall be at the
expense  of  such  indemnified  party  unless:

          (i)   the indemnifying party has agreed to pay such fees and expenses;
     or

          (ii)  the  indemnifying  party shall have failed to assume the defense
     of  such action or proceeding and employ counsel reasonably satisfactory to
     such  indemnified  party  in  any  such  action  or  proceeding;  or

          (iii)  the  named  parties to any such action or proceeding (including
     any  impleaded  parties)  include  both  such  indemnified  party  and  the
     indemnifying  party,  and such indemnified party shall have been advised by
     counsel  that  there  may  be  one or more legal defenses available to such
     party  which  are  different  from  or additional to those available to the
     indemnifying  party  (in which case, if such indemnified party notifies the
     indemnifying  party in writing that it elects to employ separate counsel at
     the  expense  of  the  indemnifying party, the indemnifying party shall not
     have the right to assume the defense of such action or proceeding on behalf
     of  such  indemnified  party).

     The indemnifying party shall not, in connection with any one such action or
proceeding  or  separate  but  substantially  similar  or  related  actions  or
proceedings in the same jurisdiction arising out of the same general allegations
or  circumstances,  be  liable for the reasonable fees and expenses of more than
one separate firm of attorneys at any time for the indemnified party, which firm
shall  be  designated  in  writing  by  the  indemnified  party.

          11.  Contribution.  In  order  to  provide  for  contribution  in
               ------------
circumstances  in  which  the  indemnification  provided for in Section 10(a) or
10(b)  hereof  is for any reason held to be unavailable to any party entitled to
such  indemnification,  each  indemnifying  party shall contribute to the amount
paid or payable by such indemnified party as a result of losses, claims, damages
and  liabilities  of  the nature contemplated by such indemnification provisions
(including  any  investigation,  legal and other expenses incurred in connection
with,  and  amounts paid in settlement of, any action, suit or proceeding or any
claims asserted) to which the Company and the Placement Agent may be subject, in
such  proportions so that the Placement Agent is responsible for that portion in
each  case  represented  by  the  percentage  that  the respective placement fee
appearing  in  Section 4(c) of this Agreement bears to the offering price of the
Shares,  and  the  Company  is  responsible for the remaining portion; provided,
however, that no person guilty of fraudulent misrepresentation shall be entitled
to  contribution  from  any  person  who  was  not  guilty  of  such  fraudulent
misrepresentation.  For  purpose  of  this  Section 11, each person, if any, who
controls  the  Placement Agent within the meaning of Section 15 of the Act shall
have the same rights to contribution as the Placement Agent, and each person, if
any,  who controls the Company within the meaning of Section 15 of the Act, each
officer  of  the  Company  and  each director of the Company shall have the same
right  to  contribution  as  the  Company,  subject  in  each  case to the prior
sentence.  Any  party  entitled  to contribution will, promptly after receipt of
notice  of  commencement of any action, suit or proceeding against such party in
respect of which claim for contribution may be sought, promptly notify the other
party  or parties in writing of the commencement thereof, but the omission to so
notify  such  party  or parties shall not relieve the party or parties from whom
contribution  may  be  sought  from  any  other  obligation  it or they may have
hereunder or otherwise than under this Section 11.  No party shall be liable for
contribution  with  respect  to any action or claim settled without its consent.

          12.  Representations  and  Agreements  to  Survive  Delivery.  All
               -------------------------------------------------------
representations,  warranties  or  agreements  of the Company or of the Placement
Agent herein or in certificates delivered pursuant hereto shall remain operative
and  in  full


                                        5

force  and  effect  regardless  of any investigation made by or on behalf of the
Placement  Agent or any controlling person, the Company, or any of its officers,
directors  or  controlling  persons,  and  shall survive delivery of the Shares.

          13.  Termination.  Each  of  the  Company's  and the Placement Agent's
