Gentlemen:

                                Engagement Letter
                                -----------------

         Further  to  our  discussions,  this  will  confirm  our  understanding
pursuant to which NM  Rothschild & Sons Canada  Limited and NM Rothschild & Sons
(Washington)  LLC  (jointly   "Rothschild")   have  been  retained  by  InfoCast
Corporation  ("InfoCast"),  on a  non-exclusive  basis,  to  provide  investment
banking and financial  advisory  services to InfoCast on matters relating to its
financial affairs and business  activities.  Rothschild will involve its offices
and personnel from London and New York as required in its judgement to carry out
this  engagement and when a placement of securities of InfoCast is  contemplated
(see  Placement Fee  overleaf)  Rothschild  will involve ABN AMRO  Rothschild to
assist Rothchild in the fundraising.

SERVICES TO BE PROVIDED

         In rendering our advice,  Rothschild  will work closely with management
of InfoCast in understanding  InfoCast's  objectives and assist in analysing and
developing  corporate  and  financial  strategies  and plans to  implement  such
objectives.  Our investment  banking and financial advisory services will relate
primarily to advice in respect of the matters  referred to in Schedule A to this
agreement,  as  requested  by senior  management  or the board of  directors  of
InfoCast.




FEES AND EXPENSES

WORK FEE

         In  consideration  for its services,  Rothschild shall be entitled to a
monthly  work fee (the  "WorkFee")  of US$50,000  payable  monthly in arrears to
Rothschild by InfoCast.

PERFORMANCE FEE

         In  the  event  a  Transaction  is  implemented   during  the  term  of
Rothschild's engagement, or within a period of one year after the termination of
Rothschild's  engagement  hereunder on which  Rothschild  worked or with a party
identified by Rothschild  during the term of this agreement,  InfoCast agrees to
pay a further fee of 3% of the Value of the Transaction (the "Performance  Fee")
to Rothschild in recognition of Rothschild's  contribution  to the  Transaction.
For the  purposes  of this  engagement  letter,  "Transaction"  shall  mean  any
acquisition,  merger,  alliance or business  combination which involves InfoCast
and which shall be valued for  purposes of this  Performance  Fee to include any
debt incurred or assumed by the purchaser or parties in the  combination and any
shares  issued  or to be issued as part of the  consideration  for any  possible
transaction.

         In the event that a  Performance  Fee  becomes  payable by  InfoCast to
Rothschild  hereunder,  no Work Fees  previously  paid or payable by InfoCast to
Rothschild  hereunder shall be credited against or deducted from the Performance
Fee.

PLACEMENT FEE

         In the event that there is a private placement or sale of securities of
InfoCast during the term of this engagement other than pursuant to a transaction
described  under  Performance  Fee  above,  Rothschild,  as the  agent  for  the
offering,  will be paid a commission  on the total value of the proceeds  raised
that is consistent  with current  industry  norms. In the event that a Placement
Fee becomes payable by InfoCast to Rothschild hereunder, no Work Fees previously
paid or payable by InfoCast to Rothschild hereunder shall be credited against or
deducted from the Placement Fee.

EXPENSES

         InfoCast  agrees to reimburse  Rothschild or to cause  Rothschild to be
reimbursed  promptly  upon  request  made by  Rothschild  from  time to time for
out-of-pocket  expenses  incurred by Rothschild and its affiliates in connection
with  Rothschild's  engagement  hereunder,  including  the  reasonable  fees and
expenses of Rothschild's counsel and of any chartered accountants who, in either
case,  may be  retained  only  with the  consent  of  InfoCast,  Out-of-  pocket
expenses,  other than legal and accounting  fees and expenses,  shall not exceed
US$25,000 in the aggregate  without the consent of InfoCast.  The payments to be
made under this paragraph


                                       -2-



are in addition to any other payments to be made hereunder and the obligation to
make such payments shall survive any  expiration or termination of  Rothschild's
retainer hereunder.

         InfoCast also agrees to reimburse  Rothschild for expenses  incurred in
its due  diligence  of the  company  prior  to  this  agreement  being  rendered
effective, such expenses not to exceed US$10,000.

EFFECTIVE DATE & TERMINATION

         This  Agreement  shall  commence  as of the  date  Rothschild  notifies
InfoCast of its completion of  satisfactory  due diligence.  Thereafter,  either
party may terminate this Agreement at any time, with or without cause, by giving
the other party 15 days written notice.

INDEMNITY

         In addition to payment of the fees and  reimbursements of out-of-pocket
expenses  payable by InfoCast  hereunder,  InfoCast agrees to indemnify and hold
harmless   Rothschild  and  its  affiliates,   and  each  of  their   respective
shareholders,  officers,  directors,  employees  and agents,  to the full extent
lawful from and against any and all claims, damages, actions, losses or expenses
(or actions  including  shareholder  actions in respect  thereof) as suffered or
incurred   (including   all  reasonable   expenses  and   reasonable   fees  and
disbursements  of  counsel  of  each  indemnified  party  and  other  reasonable
out-of-pocket expenses suffered or incurred in connection with any investigation
of and preparation for any such pending or threatened claims and actions and any
potential or actual litigation or regulatory investigations or hearings or other
proceedings  arising  therefrom)  related to or arising out of or in  connection
with  Rothschild's  engagement  hereunder or any services  rendered by Rothchild
hereunder,  provided, however, there shall be excluded from such indemnification
any such claim, damage,  action, loss or expense or portion thereof that results
from any action by  Rothschild,  other than an action  undertaken  at InfoCast's
request  or  with  InfoCast's  consent,  that  is  found  in  a  final  judicial
determination  to  constitute  bad faith,  wilful  misconduct  or  negligence on
Rothchild's part.

         InfoCast agrees that it will not,  without the prior written consent of
Rothschild,  settle or compromise or consent to the entry of any judgment in any
pending or  threatened  claim,  action,  suit or  proceeding in respect of which
indemnification  may be sought by  Rothschild  or any  other  indemnified  party
hereunder (whether or not Rothschild or any other indemnified party is an actual
or  potential  party to such  claim,  action,  suit or  proceeding)  unless such
settlement,   compromise  or  consent  includes  an  unconditional   release  of
Rothschild and each other indemnified party hereunder from all liability arising
out of  such  claim,  action,  suit  or  proceeding  without  any  admission  of
negligence,  wilful  misconduct  or bad faith by  Rothschild  or an  indemnified
party.

         InfoCast and  Rothschild  agree that if any  indemnification  sought by
Rothschild or any other  indemnified party pursuant to this agreement is held by
a court to be unavailable for


                                       -3-



any  reason  other  than the bad  faith,  wilful  misconduct  or  negligence  of
Rothschild or other indemnified party, as the case may be, InfoCast,  on the one
hand, and Rothschild,  on the other hand, will contribute to the losses, claims,
damages,  liabilities  and  expenses  for  which  such  indemnification  is held
unavailable  in such  proportion  as is  appropriate  to  reflect  the  relative
benefits to InfoCast,  on the one hand,  and  Rothschild,  on the other hand, in
connection  with the subject matter for which  Rothschild is engaged  hereunder,
subject  to  the  limitation   that,  in  any  event,   Rothschild's   aggregate
contribution  to all claims,  damages,  liabilities and expenses with respect to
which  contribution  is available  hereunder from Rothschild will not exceed the
aggregate  amount  of fees  paid by  InfoCast  to  Rothschild  pursuant  to this
Agreement.

         The  foregoing  rights of indemnity  and  contribution  and  agreements
relating thereto shall be in addition to any rights that Rothschild or any other
indemnified  party may have at common  law or  otherwise.  No  investigation  or
failure to investigate by Rothschild or any other indemnified party shall impair
the  foregoing   indemnification  and  contribution   agreement  or  any  rights
Rothschild or any other indemnified party may have.

         Any  expiration or  termination of this agreement by any party will not
affect  Rothschild's  rights or the  rights of any  other  indemnified  party at
common law or to receive indemnification or contribution.
