<PAGE>
                                      -11-

      (c)   states that the escrow securities are delivered only for the
            purposes of the business combination and that they will be released
            from escrow only after the Escrow Agent receives the information
            described in section 6.4;

      (d)   if any share certificates or other evidence of the escrow securities
            have been delivered to the depositary, requires the depositary to
            return to the Escrow Agent, as soon as practicable, any share
            certificates or other evidence of escrow securities that are not
            released from escrow into the business combination; and

      (e)   where applicable, requires the depositary to deliver or cause to be

            certificates or other evidence of additional escrow securities that
            you acquire under the business combination.

6.4 RELEASE OF ESCROW SECURITIES BY DEPOSITARY

The Escrow Agent will release from escrow the tendered escrow securities when
the Escrow Agent receives a declaration signed by the depositary or, if the
direction identifies the depositary as acting on behalf of another person or
company in respect of the business combination, by that other person or company,
that:

      (a)   the terms and conditions of the business combination have been met
            or waived; and

      (b)   the escrow securities have either been taken up and paid for or are
            subject to an unconditional obligation to be taken up and paid for
            under the business combination.

6.5 ESCROW OF NEW SECURITIES

If you receive securities (new securities) of another issuer (successor issuer)
in exchange for your escrow securities, the new securities will be subject to
escrow in substitution for the tendered escrow securities if, immediately after
completion of the business combination:

      (a)   the successor issuer is not an exempt issuer (as defined in section
            3.2 of the Policy);

      (b)   you are a principal (as defined in section 3.5 of the Policy) of the
            successor issuer; and

      (c)   you hold more than 1% of the voting rights attached to the successor
            issuer's outstanding securities (In calculating this percentage,
            include securities that may be issued to you under outstanding
            convertible securities in both your securities and the total
            securities outstanding.)

6.6 RELEASE FROM ESCROW OF NEW SECURITIES

(1)   As soon as reasonably practicable after the Escrow Agent receives:

<PAGE>
                                      -12-

      (a)   a certificate from the successor issuer signed by a director or
            officer of the successor issuer authorized to sign

            (i)   stating that it is a successor issuer to the Issuer as a
                  result of a business combination and whether it is an emerging
                  issuer or an established issuer under the Policy, and

            (ii)  listing the Securityholders whose new securities are subject
                  to escrow under section 6.5,

the escrow securities of the Securityholders whose new securities are not
subject to escrow under section 6.5 will be released, and the Escrow Agent will
send any share certificates or other evidence of the escrow securities in the
possession of the Escrow Agent in accordance with section 2.3.

(2)   If your new securities are subject to escrow, unless subsection (3)
      applies, the Escrow Agent will hold your new securities in escrow on the
      same terms and conditions, including release dates, as applied to the
      escrow securities that you exchanged.

(3)   If the Issuer is

      (a)   an emerging issuer, the successor issuer is an established issuer,
            and the business combination occurs 18 months or more after the
            Issuer's listing date, all escrow securities will be released
            immediately; and

      (b)   an emerging issuer, the successor issuer is an established issuer,
            and the business combination occurs within 18 months after the
            Issuer's listing date, all escrow securities that would have been
            released to that time, if the Issuer was an established issuer on
            its listing date, will be released immediately. Remaining escrow
            securities will be released in equal instalments on the day that is
            6 months, 12 months and 18 months after the Issuer's listing date.

                       PART 7 RESIGNATION OF ESCROW AGENT

(1)   If the Escrow Agent wishes to resign as escrow agent, the Escrow Agent
      will give written notice to the Issuer.

(2)   If the Issuer wishes to terminate the Escrow Agent as escrow agent, the
      Issuer will give written notice to the Escrow Agent.

(3)   If the Escrow Agent resigns or is terminated, the Issuer will be
      responsible for ensuring that the Escrow Agent is replaced not later than
      the resignation or termination date by another escrow agent that is
      acceptable to the securities regulators having jurisdiction in the matter
      and that has accepted such appointment, which appointment will be binding
      on the Issuer and the Securityholders.

<PAGE>
                                      -13-

(4)   The resignation or termination of the Escrow Agent will be effective, and
      the Escrow Agent will cease to be bound by this Agreement, on the date
      that is 60 days after the date of receipt of the notices referred to above
      by the Escrow Agent or Issuer, as applicable, or on such other date as the
      Escrow Agent and the Issuer may agree upon (the "resignation or
      termination date"), provided that the resignation or termination date will
      not be less than 10 business days before a release date.

(5)   If the Issuer has not appointed a successor escrow agent within 60 days of
      the resignation or termination date, the Escrow Agent will apply, at the
      Issuer's expense, to a court of competent jurisdiction for the appointment
      of a successor escrow agent, and the duties and responsibilities of the
      Escrow Agent will cease immediately upon such appointment.

(6)   On any new appointment under this section, the successor Escrow Agent will
      be vested with the same powers, rights, duties and obligations as if it
      had been originally named herein as Escrow Agent, without any further
      assurance, conveyance, act or deed. The predecessor Escrow Agent, upon
      receipt of payment for any outstanding account for its services and
      expenses then unpaid, will transfer, deliver and pay over to the successor
      Escrow Agent, who will be entitled to receive, all securities, records or
      other property on deposit with the predecessor Escrow Agent in relation to
      this Agreement and the predecessor Escrow Agent will thereupon be
      discharged as Escrow Agent.

(7)   If any changes are made to Part 8 of this Agreement as a result of the
      appointment of the successor Escrow Agent, those changes must not be
      inconsistent with the Policy and the terms of this Agreement and the
      Issuer to this Agreement will file a copy of the new Agreement with the
      securities regulators with jurisdiction over this Agreement and the escrow
      securities.

                     PART 8 OTHER CONTRACTUAL ARRANGEMENTS

8.1 ESCROW AGENT NOT A TRUSTEE

The Escrow Agent accepts duties and responsibilities under this Agreement, and

hereunder as a trustee.

securities within escrow under this Agreement.

including, without limitation, legal fees and expenses, directly or indirectly
arising out of, in connection with, or in respect of, this Agreement, except

      any notice, direction, instruction, order, certificate, confirmation,

      purportedly signed by any officer or person required to or entitled to
      execute and deliver to the Escrow Agent any such Document in connection
      with this Agreement, not only as to its due execution and the validity and
      effectiveness of its provisions, but also as to the truth or accuracy of
      any information therein contained, which it in good faith believes to be
      genuine.

(2)   The Escrow Agent will not be bound by any notice of a claim or demand with
      respect thereto, or any waiver, modification, amendment, termination or
      rescission of this Agreement unless received by it in writing, and signed
      by the other Parties and approved by the Exchange, and, if the duties or
      indemnification of the Escrow Agent in this Agreement are affected, unless
      it has given its prior written consent.

(3)   The Escrow Agent may consult with or retain such legal counsel and
      advisors as it may reasonably require for the purpose of discharging its
      duties or determining its rights under this Agreement and may rely and act
      upon the advice of such counsel or advisor. The Escrow Agent will give
      written notice to the Issuer as soon as practicable that it has retained
      legal counsel or other advisors. The Issuer will pay or reimburse the
      Escrow Agent for any reasonable fees, expenses and disbursements of such
      counsel or advisors.

(4)   In the event of any disagreement arising under the terms of this
      Agreement, the Escrow Agent will be entitled, at its option, to refuse to

      jurisdiction.

      any other agreement, including any agreement referred to in this
      Agreement, to which the Escrow Agent is not a party.

(6)   The Escrow Agent will have the right not to act and will not be liable for
      refusing to act unless it has received clear and reasonable documentation
      that complies with the terms of this Agreement. Such documentation must
      not require the exercise of any discretion or independent judgment.

(7)   The Escrow Agent is authorized to cancel any share certificate delivered
      to it and hold such Securityholder's escrow securities in electronic, or
      uncertificated form only, pending release of such securities from escrow.

(8)   The Escrow Agent will have no responsibility with respect to any escrow
      securities in respect of which no share certificate or other evidence or
      electronic or uncertificated form of these securities has been delivered
      to it, or otherwise received by it.

8.7 LIMITATION OF LIABILITY OF ESCROW AGENT

The Escrow Agent will not be liable to any of the Parties hereunder for any
action taken or omitted to be taken by it under or in connection with this
Agreement, except for losses directly, principally and immediately caused by its
bad faith, wilful misconduct or gross negligence. Under no circumstances will
the Escrow Agent be liable for any special, indirect, incidental, consequential,
exemplary, aggravated or punitive losses or damages hereunder, including any
loss of profits, whether foreseeable or unforeseeable. Notwithstanding the
foregoing or any other provision of this Agreement, in no event will the
collective liability of the Escrow Agent under or in connection with this
Agreement to any one or more Parties, except for losses directly caused by its

under this Agreement, which fees are subject to revision from time to time on 30
days' written notice. The Issuer will reimburse the Escrow Agent for its
expenses and disbursements. Any amount due under this section and unpaid 30 days
after request for such payment, will bear interest from the expiration of such
period at a rate per annum equal to the then current rate charged by the Escrow
Agent, payable on demand.

8.9 INDEMNIFICATION OF THE EXCHANGE

(1)   The Issuer and each Securityholder jointly and severally:

      (a)   release, indemnify and save harmless the Exchange from all costs
            (including legal cost, expenses and disbursements), charges, claims,
            demands, damages, liabilities, losses and expenses incurred by the
            Exchange;

            action,

arising from any and every act or omission committed or omitted by the Exchange,
in connection with this Agreement, even if said act or omission was negligent,
or constituted a breach of the terms of this Agreement.

(2)   This indemnity survives the release of the escrow securities and the
