12 months after the listing date	1/2 of your remaining escrow securities
18 months after the listing date	your remaining escrow securities

*In the simplest case, where there are no changes to the escrow securities initially deposited and no additional escrow securities, then the release schedule outlined above results in the escrow securities being released in equal tranches of 25%.

2.1.2Alternate meaning of "listing date"

2.1.4Additional escrow securities

This indemnity survives the release of the escrow securities, the resignation or termination of the Escrow Agent and the termination of this Agreement.

8.6Additional Provisions

(1)The Escrow Agent will be protected in acting and relying reasonably upon any notice, direction, instruction, order, certificate, confirmation, request, waiver, consent, receipt, statutory declaration or other paper or document (collectively referred to as "Documents") furnished to it and 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 securities regulators with jurisdiction as set out in section 10.6, 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 comply with any and all demands whatsoever until the dispute is settled either by a written agreement among the Parties or by a court of competent jurisdiction.

(5)The Escrow Agent will have no duties or responsibilities except as expressly provided in this Agreement and will have no duty or responsibility under the National Policy 46-201 or arising under 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.

(9)Any entity resulting from the merger, amalgamation or continuation of Computershare or succeeding to all or substantially all of its transfer agency business (by sale of such business or otherwise), shall thereupon automatically become the Escrow Agent hereunder without further act or formality. This Agreement shall enure to the benefit of and be binding upon the parties hereto and their successors and assigns.

8.7Limitation 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 bad faith or willful misconduct, exceed the amount of its annual fees under this Agreement or the amount of three thousand dollars ($3,000.00), whichever amount shall be greater. 

8.8Remuneration of Escrow Agent

The Issuer will pay the Escrow Agent reasonable remuneration for its services 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.
