authorized by all necessary corporate action, and no further consent or
authorization of the Company or its Board of Directors or stockholders is
required. This Agreement has been duly executed and delivered, and constitutes a
valid and binding obligation of the Company enforceable against the Company in
accordance with its terms, except as such enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium, liquidation,
conservatorship, receivership or similar laws relating to, or affecting
generally the enforcement of, creditor's rights and remedies or by other

the Company is or may become bound to issue additional shares of the capital
stock of the Company or options, securities or rights convertible into shares of

rights, warrants, or options of the Company issued prior to the Closing complied
with all applicable United States Federal and state and Canadian and provincial
securities laws, and no stockholder has a right of rescission or damages with
respect thereto which would have a Material Adverse Effect on the Company's
financial condition or operating results. The Company has made available to the
Purchaser on request true and correct copies of the Company's Articles of
Incorporation as in effect on the date hereof (the "Articles"), and the
Company's Bylaws as in effect on the date hereof (the "Bylaws"). The Principal

and outstanding, fully paid and non-assessable, and the Purchaser shall be
entitled to all rights accorded to a holder of Common Stock.

     (e) No Conflicts. The execution, delivery and performance of this Agreement
by the Company and the consummation by the Company of the transactions
contemplated herein do not and will not (i) violate any provision of the
Company's Articles or Bylaws, (ii) conflict with, or constitute a default (or an
event which with notice or lapse of time or both would become a default) under,
or give to others any rights of termination, amendment, acceleration or
cancellation of, any agreement, mortgage, deed of trust, indenture, note, bond,
license, lease agreement, instrument or obligation to which the Company is a
party, (iii) create or impose a lien, charge or encumbrance on any property of

properties or assets are bound, or (iv) result in a violation of any United
States Federal, state, local or Canadian, provincial, or other foreign statute,

and state or Canadian or provincial securities laws and regulations) applicable
to the Company or any of its subsidiaries or by which any property or asset of
the Company or any of its subsidiaries are bound or affected, except, in all
cases, for such conflicts, defaults, termination, amendments, accelerations,
cancellations and violations as would not, individually or in the aggregate,
have a Material Adverse Effect. The business of the Company and its subsidiaries
is not being conducted in violation of any laws, ordinances or regulations of
any governmental entity, except for possible violations which singularly or in
the aggregate do not and will not have a Material Adverse Effect. The Company is
not required under any United States Federal, state or local or Canadian or

of, or make any filing or registration with, any court or governmental agency in
order for it to execute, deliver or perform any of its obligations under this

                                   ARTICLE IX

                                 INDEMNIFICATION

     Section 9.1 General Indemnity. The Company agrees to indemnify and hold
harmless the Purchaser (and its directors, officers, affiliates, agents,
successors and assigns) from and against any and all losses, liabilities,
deficiencies, costs, damages and expenses (including, without limitation,
reasonable attorney's fees, charges and disbursements) incurred by the Purchaser
as a result of any inaccuracy in or breach of the representations, warranties or
covenants made by the Company herein. The Purchaser agrees to indemnify and hold
harmless the Company and its directors, officers, affiliates, agents, successors
and assigns from and against any and all losses, liabilities, deficiencies,
costs, damages and expenses (including, without limitation, reasonable attorneys
fees, charges and disbursements) incurred by the Company as result of any
inaccuracy in or breach of the representations, warranties or covenants made by
the Purchaser herein.

     Section 9.2 Indemnification Procedure. Any party entitled to
indemnification under this Article IX (an "indemnified party") will give written
notice to the indemnifying party of any matters giving rise to a claim for
indemnification; provided, that the failure of any party entitled to
indemnification hereunder to give notice as provided herein shall not relieve
the indemnifying party of its obligations under this Article IX except to the
extent that the indemnifying party is actually prejudiced by such failure to
give notice. In case any action, proceeding or claim is brought against an
indemnified party in respect of which indemnification is sought hereunder, the
indemnifying party shall be entitled to participate in and, unless in the
reasonable judgment of counsel to the indemnified party a conflict of interest
between it and the indemnifying party may exist with respect of such action,
proceeding or claim, to assume the defense thereof with counsel reasonably
satisfactory to the indemnified party. In the event that the indemnifying party
advises an indemnified party that it will contest such a claim for
indemnification hereunder, or fails, within thirty (30) days of receipt of any
indemnification notice to notify, in writing, such person of its election to
defend, settle or compromise, at its sole cost and expense, any action,
proceeding or claim (or discontinues its defense at any time after it commences
such defense), then the indemnified party may, at its option, defend, settle or
otherwise compromise or pay such action or claim. In any event, unless and until
the indemnifying party elects in writing to assume and does so assume the
defense of any such claim, proceeding or action, the indemnified party's costs
and expenses arising out of the defense, settlement or compromise of any such
action, claim or proceeding shall be losses subject to indemnification
hereunder. The indemnified party shall cooperate fully with the indemnifying
party in connection with any settlement negotiations or defense of any such
action or claim by the indemnifying party and shall furnish to the indemnifying
party all information reasonably available to the indemnified party which
relates to such action or claim. The indemnifying party shall keep the
indemnified party fully apprised at all times as to the status of the defense or
any settlement negotiations with respect thereto. If the indemnifying party
elects to defend any such action or claim, then the indemnified party shall be
entitled to participate in such defense with counsel of its choice at its sole
cost and expense. The indemnifying party shall not be liable for any settlement
of any action, claim or proceeding effected without its prior written consent.
Notwithstanding anything in this Article IX to the contrary, the indemnifying
party shall

                                       13
<PAGE>

not, without the indemnified party's prior written consent, settle or compromise
any claim or consent to entry of any judgment in respect thereof which imposes
any future obligation on the indemnified party or which does not include, as an
unconditional term thereof, the giving by the claimant or the plaintiff to the
indemnified party of a release from all liability in respect of such claim. The
indemnification required by this Article IX shall be made by periodic payments
of the amount thereof during the course of investigation or defense, as and when
bills are received or expense, loss, damage or liability is incurred, so long as
the indemnified party irrevocably agrees to refund such moneys if it is
ultimately determined by a court of competent jurisdiction that such party was
not entitled to indemnification. The indemnity agreements contained herein shall
be in addition to (a) any cause of action or similar rights of the indemnified
party against the indemnifying party or others, and (b) any liabilities the
indemnifying party may be subject to.

                                   ARTICLE X
