                  that  the  common  stock   purchase   agreement   between  the
                  Corporation and Radyr Group Investments dated October 18, 1999
                  and the related call option have been terminated.

10.      Rights of Termination

          (a) Litigation.  If any enquiry,  action, suit, investigation or other
proceeding  whether  formal or informal is instituted or threatened or any order
is made by any federal,  provincial or other governmental  authority in relation
to the Corporation which, in the reasonable opinion of the Underwriter, operates
to  prevent  or  restrict  the  distribution  or  trading  of the  Units  or the
Underlying  Securities,  the Underwriter shall be entitled, at its option and in
accordance  with  subparagraph  10(g)  of this  Agreement,  to  terminate  their
obligations under this Agreement (and the obligations of the Purchasers arranged
by it to purchase  Units) by notice to that effect given to the  Corporation any
time prior to the Closing Time.

          (b) Disaster  Out Clause.  In the event that prior to the Closing Time
there should  develop,  occur or come into effect any  occurrence of national or
international  consequence or any event, action,  condition,  law,  governmental
regulation,  inquiry or other occurrence of any nature  whatsoever which, in the
reasonable opinion of the Underwriter,  seriously adversely affects or involves,
or will seriously adversely affect or involve, the Canadian financial markets or
the business, operations or affairs of the Corporation, the Underwriter shall be
entitled at its option, in accordance with subparagraph 10(g) of this Agreement,
to terminate their  obligations under this Agreement (and the obligations of the
Purchasers  arranged by it to purchase  Units) by written  notice to that effect
given to the Corporation prior to the Closing Time.

          (c) Market Out Clause. If, prior to the Closing Time, the state of the
financial markets becomes such that the Units cannot, in the reasonable  opinion
of the Underwriter, be profitably marketed, the Underwriter shall be entitled at
its  option,  in  accordance  with  subparagraph  10(g)  of this  Agreement,  to
terminate  their  obligations  under this Agreement (and the  obligations of the
Purchasers  arranged by them to purchase Units) by written notice to that effect
given to the Corporation prior to the Closing Time.

         (d) Change in  Material  Fact.  In the event that prior to the  Closing
Time there should  occur any material  change,  there should be  discovered  any
previously  undisclosed  material  fact,  or there  should occur a change in any
material fact such as is contemplated by subparagraph 6(a), which results or, in
the  reasonable  opinion of the  Underwriter,  could  reasonably  be expected to
result,  in the  Purchasers  of a  material  number  of Units  exercising  their
contractual right of rescission granted to the Underwriter and the Purchasers in
respect  of the Units or the  rights of  rescission  under  the  Securities  Act
(Ontario) or the corresponding  provisions of applicable securities  legislation
in  the  other  Qualifying  Provinces  or,  in  the  reasonable  opinion  of the
Underwriter,  has or could  reasonably  be expected  to have a material  adverse
effect  on  the  market  price  or  value  of  the  Underlying  Securities,  the
Underwriter  shall be entitled,  at its option,  in accordance with subparagraph
10(g), to terminate their  obligations under this Agreement (and the obligations
of the  Purchasers  arranged by it to purchase  Units) by written notice to that
effect given to the Corporation prior to the Closing Time.
<PAGE>

          (e) Cease Trade Order. In the event that any order to cease trading in
securities of the  Corporation is made or threatened by a Securities  Regulator,
the  Underwriter   shall  be  entitled,   at  its  option,  in  accordance  with
subparagraph  10(g) of this Agreement,  to terminate its obligations  under this
Agreement  (and the  obligations  of the  Purchasers  arranged by it to purchase
Units) by written  notice to that effect given to the  Corporation  prior to the
Closing Time.

          (f)  Non-Compliance  With Conditions.  The Corporation agrees that all
terms and  conditions in this  Agreement  shall be construed as  conditions  and
complied  with so far as the same relate to acts to be performed or caused to be
performed  by the  Corporation  that  it  will  use  its  best  efforts  (or all
commercially  reasonable  efforts, as applicable) to cause such conditions to be
complied with,  and any breach or failure by the  Corporation to comply with any
of such conditions shall entitle the  Underwriter,  to terminate its obligations
under this  Agreement (and the  obligations of the Purchasers  arranged by it to
purchase Units) by notice to that effect given to the Corporation at or prior to
the Closing Time. The  Underwriter may waive, in whole or in part, or extend the
time for  compliance  with, any terms and  conditions  without  prejudice to its
rights in  respect  of any other of such  terms and  conditions  or any other or
subsequent breach or non-compliance,  provided that any such waiver or extension
shall be binding upon the Underwriter  only if the same is in writing and signed
by the Underwriter.

          (g)  Exercise  of  Termination   Rights.  The  rights  of  termination
contained in subparagraphs  10(a), (b), (c), (d), (e) and (f) are in addition to
any other rights or remedies the Underwriter may have in respect of any default,
act or failure to act or  non-compliance by the in respect of any of the matters
contemplated  by  this  Agreement  or  otherwise.  In  the  event  of  any  such
termination,  there shall be no further liability on the part of the Underwriter
to the Corporation or on the part of the  Corporation to the Underwriter  except
in  respect  of any  liability  which may have  arisen or may arise  after  such
termination  in respect of acts or  omissions  prior to such  termination  under
paragraphs 11, 13 and 14.

11.  Expenses.  Whether  or not the  sale of the  Units or the  issuance  of the
Underlying  Securities  upon  exercise  of such Units  shall be  completed,  all
reasonable out of pocket  expenses of or incidental to the issue and delivery of
such Units and Underlying  Securities or incidental to all matters in connection
with  the  transactions  herein  set  out  shall  be  borne  by the  Corporation
including, without limitation, expenses in connection with the issuance and sale
of the Units, all filing and  registration  fees required under Securities Laws,
the qualification of the Underlying Securities for distribution to the public in
the United  States,  the  preparation,  filing and delivery of the  Registration
Statement,  the Prospectus and any Supplementary Material, the fees and expenses
of counsel to the Corporation and all local counsel selected by the Corporation,
the Underwriter's  out-of-pocket  expenses,  the reasonable fees and expenses of
counsel  to the  Underwriter,  and all costs  incurred  in  connection  with the
preparation and printing of the Registration  Statement,  the Prospectus and any
Supplementary Material.

12. Survival of Representations and Warranties. All warranties, representations,
covenants  and  agreements  herein  contained  or  contained  in  any  documents
submitted  pursuant to this  Agreement  and in connection  with the  transaction
herein  contemplated  shall  survive the  purchase and sale of the Units and the
exercise  of such Units for the  Underlying  Securities  by the  Purchasers  and
continue in full force and effect for the benefit of the Purchasers for a period
of two years from the Closing Date and shall not be limited or prejudiced by any
investigation  made by or on behalf of the  Underwriter  in connection  with the
purchase  and  sale  of the  Units  or the  preparation  of  the  Prospectus  or
otherwise.  For greater  certainty,  and without  limiting the generality of the
foregoing,  the provisions contained in this Agreement in any way related to the
indemnification  of the  Underwriter  by the  Corporation,  or the  contribution
obligations of the  Underwriter or those of the  Corporation,  shall survive and
continue in full force and effect, indefinitely.

13. (a) Indemnity of the Corporation. The Corporation hereby agrees to indemnify
and  save  harmless  the  Underwriter  and each of  their  directors,  officers,
employees and Underwriter  from and against all  liabilities,  claims,  actions,
suits,  proceedings,  losses  (other than loss of profits),  costs,  damages and
expenses in any way caused by, or arising  directly or  indirectly  from,  or in
consequence of:

         (i)      any  misrepresentation or alleged  misrepresentation  (as such
                  term is defined in the  Securities  Act  (Ontario))  contained
                  herein or made by the  Corporation in connection with the sale
                  by the Corporation of the Units or the Underlying  Securities,
                  or in any material  change report or public  document filed or
                  issued  by  the  Corporation  or on  its  behalf,  except  any
                  information or statement relating solely to the Underwriter;

         (ii)     any  information  or  statement  (except  any  information  or
                  statement relating solely to the Underwriter) contained in the
                  Registration  Statement,  the Prospectus or any  Supplementary
                  Material or in any  certificate of the  Corporation  delivered
                  under this  Agreement or pursuant to this  Agreement  which at
                  the time and in the light of the circumstances  under which it
                  was   made    contains    or   is   alleged   to   contain   a
                  misrepresentation;

         (iii)    any omission or alleged  omission to state in the Registration
                  Statement,  the Prospectus,  any Supplementary Material or any
                  certificate of the Corporation  delivered under this Agreement
                  or pursuant to this  Agreement any fact (except facts relating
                  solely to the Underwriter),  whether material or not, required
                  to be  stated  in such  document  or  necessary  to  make  any
                  statement  in such  document  not  misleading  in light of the
                  circumstances under which it was made;
<PAGE>

         (iv)     any  order  made  or  enquiry,  investigation  or  proceedings
                  commenced or threatened by any Securities Regulator based upon
                  any untrue  statement or omission or alleged untrue  statement
                  or  alleged  omission  or  any  misrepresentation  or  alleged
                  misrepresentation  (except a statement  or omission or alleged
                  statement or omission  relating solely to the  Underwriter) in
                  the   Registration   Statement,    the   Prospectus   or   any
                  Supplementary  Material  or based  upon any  failure to comply
                  with  applicable  Securities  Laws  (other than any failure or
                  alleged failure to comply by the  Underwriter),  preventing or
                  restricting  the trading in or the sale or distribution of the
                  Units or the Underlying Securities; or

         (v)      the   non-compliance   or   alleged   non-compliance   by  the
                  Corporation with any applicable Securities Laws, including the
                  Corporation's non-compliance with any statutory requirement to
                  make any document available for inspection.

         (b) Notification of Claims. If any matter or thing contemplated by this
paragraph  (any such matter or thing being referred to as a "Claim") is asserted
against  any person or  Corporation  in respect of which  indemnification  is or
might  reasonably be considered to be provided,  such person or Corporation (the
"Indemnified Party") will notify the Corporation or the Corporation, as the case
may be (as  applicable,  the  "Indemnifying  Party") as soon as  possible of the
nature of such  Claim and the  Indemnifying  Party  shall be  entitled  (but not
required)  to assume the  defence of any suit  brought  to enforce  such  Claim;
provided,  however,  that the defence  shall be conducted  through legal counsel
acceptable to the Indemnified Party,  acting reasonably,  and that no settlement
of any such Claim may be made by the Indemnifying Party or the Indemnified Party
without the prior written  consent of the other parties,  such consent not to be
unreasonably withheld.

          (c) Right of  Indemnity  in  Favour of  Others.  With  respect  to any
Indemnified  Party who is not a party to this Agreement,  the Underwriter or the
Corporation,  as  applicable,  shall  obtain and hold the rights and benefits of
this  paragraph and paragraph 14 in trust for and on behalf of such  Indemnified
Party.

          (d) Retaining Counsel.  In any such Claim, the Indemnified Party shall
have the right to retain  other  counsel to act on his, her or its behalf and to
participate in the defence thereof,  provided that the fees and disbursements of
such counsel shall be paid by the Indemnified Party unless: (i) the Indemnifying
Party and the  Indemnified  Party shall have mutually agreed to the retention of
the other counsel,  (ii) the  Indemnifying  Party fails to assume the defence of
such  Claim on behalf of the  Indemnified  Party  within  ten days of  receiving
notice of such Claim,  or (iii) the named  parties to any such Claim  (including
any added third or impleaded  party) include both the Indemnified  Party and the
Indemnifying  Party and the Indemnified Party shall have been advised by counsel
that  representation  of the Indemnified  Party by counsel for the  Indemnifying
Party is inappropriate as a result of potential or actual differing interests of
those  represented;  in each of which cases such Indemnifier  shall not have the
right to assume the defence of such Claim on behalf of the Indemnified Party but
the  Indemnifying  Party  shall  be  liable  to  pay  the  reasonable  fees  and
disbursements   of  counsel  to  the  Indemnified   Party;   provided  that  the
Indemnifying  Party shall not be obligated to pay fees and expenses of more than
one separate legal firm for all Indemnified Parties, as a group.
<PAGE>

14. (a) Contribution.  In order to provide for a just and equitable contribution
in circumstances in which the indemnity provided in paragraph 13 would otherwise
be available  in  accordance  with its terms but is, for any reason,  held to be
unavailable to or unenforceable by the Underwriter or enforceable otherwise than
in  accordance  with  its  terms,  the  Corporation,  the  Corporation  and  the
Underwriter shall severally contribute to the aggregate of all claims, expenses,
costs and  liabilities  and all losses  (other than loss of profits) of a nature
contemplated  in paragraph 13 in such  proportions  so that the  Underwriter  is
responsible for the portion represented by the percentage that the aggregate fee
payable by the  Corporation to the Underwriter  bears to the aggregate  offering
price of the Units and the  Indemnifying  Party is responsible  for the balance.
The  Underwriter  shall  not  in any  event  be  liable  to  contribute,  in the
aggregate,  any amounts in excess of such  aggregate  fee or any portion of such
fee  actually  received.  However,  no  party  who  has  engaged  in any  fraud,
fraudulent  misrepresentation  or gross  negligence  shall be  entitled to claim
contribution  from any person  who has not  engaged  in such  fraud,  fraudulent
misrepresentation or gross negligence.

          (b) Right of Contribution  in Addition to Other Rights.  The rights to
contribution  provided  in this  paragraph  shall be in  addition  to and not in
derogation of any other right to contribution  which the Underwriter may have by
statute or otherwise at law.

          (c)  Calculation of  Contribution.  In the event that an  Indemnifying
Party may be held to be entitled to contribution  from the Underwriter under the
provisions of any statute or at law, the Indemnifying  Party shall be limited to
contribution in an amount not exceeding the lesser of:

         (i)      the portion of the full amount of the loss or liability giving
                  rise  to  such  contribution  for  which  the  Underwriter  is
                  responsible, as determined in subparagraph 14(a) above; and

         (ii)     the  amount of the  aggregate  fee  actually  received  by the
                  Underwriter from the Corporation under this Agreement.

          (d) Notice.  If the Underwriter has reason to believe that a claim for
contribution may arise,  they shall give the  Indemnifying  Party notice of such
claim in  writing,  as soon as  reasonably  possible,  but failure to notify the
Indemnifying  Party shall not relieve the  Indemnifying  Party of any obligation
which it may have to the Underwriter under this paragraph.

15.  Right  of  First  Refusal.  Subject  to  completion  of the  Offering,  the
Underwriter  is  hereby  granted  the  right  of  first  refusal  to act as lead
underwriter of any further  offering of securities of the  Corporation in Canada
and, to the extent qualified in the United States,  to participate as a managing
underwriter  in an  amount  equal to not  less  than  20%,  in any  offering  of
securities by the Corporation,  either wholly or partially in the United States,
including  a follow-on  issue of Common  Shares,  in each case,  for a period of
eighteen months from the Closing Date.
<PAGE>

16. Advertisements. The Corporation acknowledges that the Underwriter shall have
the right, subject always to paragraphs 1 and 2 of this Agreement,  at their own
expense,  to place such advertisement or advertisements  relating to the sale of
the Units or the Underlying  Securities  contemplated  herein as the Underwriter
may consider desirable or appropriate and as may be permitted by applicable law.
The  Corporation  and the  Underwriter  each  agree  that  they will not make or
publish any  advertisement  in any media  whatsoever  relating  to, or otherwise
publicize,  the transaction provided for herein so as to result in any exemption
from the  prospectus  and  registration  requirements  of applicable  securities
legislation  in any of the provinces of Canada being  unavailable  in respect of
the sale of the Units to prospective purchasers.

17. Notices.  Unless otherwise expressly provided in this Agreement,  any notice
