RECITALS

Predictive, Robex and 9548-5991 Québec Inc. (“Acquireco”), being a direct wholly-owned subsidiary of Predictive, have entered into an arrangement agreement (the “Arrangement Agreement”) dated as of the date hereof, pursuant to which Acquireco will, inter alia, acquire all of the outstanding common shares in the capital of Robex (“Robex Shares”) by way of a statutory plan of arrangement under the provisions of Chapter XVI – Division II of the Business Corporations Act (Québec), under which the holders of Robex Shares will receive ordinary shares in the capital of Predictive in accordance with the plan of arrangement (the “Proposed Transaction”).

This Agreement sets out the terms and conditions on which the Holder has agreed to support the Proposed Transaction.

The Holder is the owner of, or has the power to control or direct, the Robex Shares and Robex CDIs (collectively, the “Subject Shares”) and the convertible securities of Robex, including Robex Options, Robex DSUs, Robex PSUs, Robex RSUs and Robex Warrants (collectively, the “Robex Convertible Securities” and together with the Subject Shares, the “Subject Securities”), as applicable, listed in Schedule A hereto; provided that, for greater certainty, the term “Subject Shares” shall include any Robex Shares or Robex CDIs issuable upon the exercise of any Robex Convertible Securities, and the term “Subject Securities” shall include any and all Robex Shares, Robex CDIs, Robex Options, Robex DSUs, Robex PSUs, Robex RSUs and Robex Warrants of which the Holder acquires beneficial ownership, or control or direction over, directly or indirectly, after the date hereof.

The Holder is a director and/or officer of Robex.

Capitalized terms used in this Agreement and not otherwise defined herein that are defined in the Arrangement Agreement shall have the respective meanings ascribed thereto in the Arrangement Agreement. For greater certainty, the term “affiliate” as used in this Agreement shall have the meaning ascribed thereto in Section 1.13 of the Arrangement Agreement.

5.8 This Agreement, together with the agreements and other documents herein or therein referred to, constitute the entire agreement between the Parties hereto pertaining to the subject matter hereof and supersede all prior agreements, understandings, negotiations and discussions, whether oral or written, between the Parties with respect to the subject matter hereof. There are no representations, warranties, covenants or conditions with respect to the subject matter hereof except as contained herein.

5.9 This Agreement shall be governed by, and be construed in accordance with, the laws of the Province of Québec and the federal laws of Canada applicable therein but the reference to such laws shall not, by conflict of laws rules or otherwise, require the application of the law of any jurisdiction other than the Province of Québec.

5.10 Each Party irrevocably attorns and submits to the exclusive jurisdiction of the Québec courts situated in the City of Montreal and waives objection to the venue of any proceeding in such court or that such court provides an inconvenient forum.

5.11 Unless otherwise stated, all references in this Agreement to amounts of money are expressed in lawful money of Canada.

5.12 The Holder recognizes and acknowledges that this Agreement is an integral part of Predictive and Robex entering into the Arrangement Agreement, and that Predictive and Robex would not contemplate proceeding with the transactions contemplated by the Arrangement Agreement unless this Agreement was entered into by the Holder, and that a breach by the Holder of any covenants or other commitments contained in this Agreement will cause Predictive and Robex to sustain injury for which money damages would not be an adequate remedy at law. Therefore, the Holder agrees that, in the event of any such breach, each of Predictive and Robex shall be entitled to the remedy of specific performance of such covenants or commitments and preliminary and permanent injunctive and other equitable relief in addition to any other remedy to which it may be entitled, at law or in equity.
