The NCC shall be a non-binding advisory committee to senior management and the Board and shall meet at a minimum quarterly.

(2)            The Investor shall designate up to two (2) individuals to act as members (each such member a “NCC Member”) of the NCC, such designation exercisable at the sole discretion of the Investor from time to time by delivery of notice in writing to the Corporation given in accordance with Section 7.02.

(3)            Each NCC Member shall be entitled to: (a) receive notice of and to attend all meetings of the NCC (including by video or telephone conference call); (b) take part in discussions and deliberations of matters brought before the NCC; (c) receive all notices, consents, minutes, documents and other information and materials that are sent to members of the NCC; and (d) receive copies of all written recommendations proposed by the NCC each at substantially the same time and in substantially the same manner as the other members of the NCC.

(3)            Prior to a Liquidity Event, the Investor must advise the Corporation of the identity of the Board Designee at least thirty (30) days prior to any meeting at which directors of the Corporation are to be elected, or within ten (10) days of being notified of the record date of any meeting if the record date is within forty-five (45) days of such meeting, failing which the incumbent Board Designee shall be nominated for re-election.

(4)            If the Investor’s Ownership Percentage falls below 7.5%, then the Investor shall cause its Board Designee then elected or appointed to the Board to resign and such Investor will have no further entitlement hereunder to require the Corporation to nominate individuals for election or appointment to the Board. If within one year of the Investor’s Ownership Percentage falling below 7.5%, the Investor’s Ownership Percentage again becomes 7.5% or greater, the Investor’s rights under this Section 2.02 shall be reinstated.

(5)            Following a Liquidity Event, upon receipt of a notice pursuant to Section 2.02(1), the Corporation shall include the Board Designee on any proxy for a meeting of shareholders at which directors are to be elected and recommend that Board Designee for election to the Board.

(3)            All Board meetings shall be duly constituted notwithstanding the absence of the Board Observer and for clarity the presence or waiver of the Board Observer shall not be required for quorum of a meeting of the Board.

DISPUTE RESOLUTION

(1)            Mandatory Informal Resolution Meeting. If a dispute arises between or among the Parties in respect of any matter in relation to this Agreement, it shall be referred to authorized individuals of the relevant Parties to resolve by written notice of any one party. The authorized individuals shall endeavor to meet in person to discuss resolution of the dispute or, at a minimum, by videoconference if an in-person meeting is not practicable.

(2)            Further Actions for Resolving Disputes Involving Confidential Information. Should the Parties be unable to resolve a dispute that involves or relates to Confidential Information within twenty (20) days from the date of such written notice, the dispute shall be referred to binding confidential arbitration and administered by the ADR Institute of Canada, Inc. under its Arbitration Rules, as amended or supplemented by the provisions of this Article 5 (an “Arbitration”). The service of any notice, process, motion or any other document in connection with an Arbitration or any enforcement of any arbitration award may be made in the same manner that communications may be given under 7.02. The Arbitration will be conducted in the English language in the City of Toronto, Ontario, Canada with one arbitrator. Except as required under applicable Law, neither a Party nor an arbitrator may disclose the existence, content, or results of any arbitration related in any manner to Confidential Information without the prior written consent of the parties to the Arbitration, save and except no consent is required for disclosure to professional advisors and tax authorities in connection with or as a result of an Arbitration. The costs of an Arbitration pursuant to this provision shall be borne by the parties equally.

(3)            Further Actions for Resolving Other Disputes. Should the Parties be unable to resolve a dispute within twenty (20) days from the date of the written notice of a dispute that does not relate to or involve Confidential Information, then the Parties shall by mutual agreement submit the dispute to a neutral mediator. The Parties may also at their election waive mediation by mutual written agreement and refer the dispute to litigation, which shall be under the exclusive jurisdiction of the Courts of the Province of Ontario. The reasonable attorneys’ fees and costs related to any litigation activities shall be recoverable by the prevailing party in the litigation.

If the dispute proceeds to mediation, the authorized individuals shall have seven (7) days from the date of such written notice to each submit by email to the other Party(ies) a written list of no less than three (3), but no more than five (5), acceptable qualified mediators not affiliated with any of the Parties. Within seven (7) days from the date of receipt of such list, the authorized individuals shall rank the mediators in numerical order of preference and exchange such rankings by email with the relevant Party(ies).

If one or more names are on all of the lists, the highest-ranking person shall be designated as the mediator. If no mediator has been selected under this procedure, the Parties agree that they will each select one mediator from the list(s) submitted by the other Party(ies) and those mediators shall select and appoint another mediator to serve as the sole mediator. The mediation session shall be held within thirty (30) days after the appointment of a mediator, subject to the mediator’s availability.

If the Parties accept the mediator’s recommendations or agree on the resolution of the dispute, then the agreement will be signed by and become binding on the Parties. If no agreement is reached, then once seven (7) days has passed since the completion of mediation, any of the Parties to the dispute may refer the dispute to litigation. The Parties agree to attorn to the exclusive jurisdiction of the Courts of the Province of Ontario in the case of litigation in accordance with this provision. The costs of mediation pursuant to this provision shall be borne by the parties equally, however, reasonable attorneys’ fees and costs related to any litigation activities post- mediation shall be recoverable by the prevailing party in the litigation.

Any arbitrator appointed pursuant to Section 5.01 shall have the power to grant any legal or equitable remedy or relief available under the applicable law, including injunctive relief (whether interim and/or final) and specific performance and any measures ordered by the arbitrators may be specifically enforced by any court of competent jurisdiction. The Parties agree that any Party may have recourse to the Courts of the Province of Ontario to seek interim or provisional measures, including injunctive relief and pre-arbitral attachments or injunctions and any such request shall not be deemed incompatible with the agreement to arbitrate under this Agreement or a waiver of such right to arbitrate.

The Parties acknowledge that they have entered into this Agreement willingly with full knowledge of the obligations imposed by the terms of this Agreement. Further, the Parties acknowledge that they have been afforded the opportunity to obtain independent legal advice and confirm by the execution of this Agreement that they have either done so or waived their right to do so, and agree that this Agreement constitutes a binding legal obligation and that they are estopped from raising any claim on the basis that they have not obtained such advice.

This Agreement constitutes the entire agreement between the Parties with respect to the matters contemplated by this Agreement and supersedes all prior agreements, understandings, negotiations and discussions, whether oral or written, of the Parties related to such matters, including the Term Sheet.

If any provision of this Agreement is determined to be illegal, invalid or unenforceable by an arbitrator or any court of competent jurisdiction from which no appeal exists or is taken, that provision will be severed from this Agreement and the remaining provisions will remain in full force and effect. The Parties shall engage in good faith negotiations to replace any provision which is declared invalid or unenforceable with a valid and enforceable provision, the economic and substantive effect of which comes as close as possible to that of the invalid or unenforceable provision which it replaces.
