(c) During the Restricted Period, the Executive will not solicit or induce any person who is an employee of the Company or any of its affiliates to terminate any relationship such person may have with the Company or any of its affiliates, nor shall the Executive during such period directly or indirectly engage, employ or compensate, or cause or permit any person with which the Executive may be affiliated, to engage, employ or compensate, any employee of the Company or any of its affiliates. The Executive hereby represents and warrants that the Executive has not entered into any agreement, understanding or arrangement which is currently in effect with any employee of the Company or any of its affiliates pertaining to any business in which the Executive has participated or plans to participate, or to the employment, engagement or compensation of any such employee. (d) Without limiting the provisions of Sections 2(a), (b) and (c) above, during the Restricted Period, Williams shall not own or hold proprietary interest in, manage, be employed by or consult with, operate, join, control or participate in the ownership, management, operation or control of any person or entity that (i) competes, in any way or manner, with Sierra or its subsidiaries in the packaged entertainment or education software business anywhere in the World as such business may be conducted from time to time or (ii) markets or distributes entertainmentrelated software or services on the Internet or any similar computer network.

(f) The Executive hereby acknowledges that damages at law may be an insufficient remedy to the Company if the Executive violates the terms of this Agreement and that the Company shall be entitled, upon making the required showing, to preliminary and/or permanent injunctive relief in any court of competent jurisdiction to restrain the breach of or otherwise to specifically enforce any of the covenants contained in this Agreement without the necessity of showing any actual damage or that monetary damages would not provide an adequate remedy. Such right to an injunction shall be in addition to, and not in limitation of, any other rights or remedies the Company may have. Without limiting the generality of the foregoing, neither party shall oppose any motion the other party may make for any expedited discovery or hearing in connection with any alleged breach of this Agreement. (g) The period of time during which the provisions of this Agreement shall be in effect shall be extended by the length of time during which the Executive is in breach of the terms hereof as determined by any court of competent jurisdiction on the Company's application for injunctive relief. (h) The Executive also agrees to indemnify and hold the Company harmless from and against any and all damages and expenses, including reasonable attorneys' fees and dis bursements, resulting from any breach by him of the terms and conditions of this Agreement, which remedy is in addition to any and all other remedies that the Company may possess at law or in equity. (i) The Executive agrees that the restrictions contained in this Agreement are material to the Company and, but for the Executive's agreement to comply with such re strictions, the Company would not have entered into the Merger Agreement. 3. Governing Law; Construction. This Agreement has been executed and delivered in the State of Washington and its validity, interpretation, performance and enforcement shall be governed by the internal laws of that state. 4. Arbitration. (a) Any controversy, dispute or claim arising out of or relating to this Agreement or the breach hereof which cannot be settled by mutual agreement (other than with respect to the matters for which the Compa ny may, but shall not be required to, seek injunctive re lief) shall be finally settled by binding arbitration in accordance with the Federal Arbitration Act (or if not ap plicable, the applicable state arbitration law) as follows: Any party who is aggrieved shall deliver a notice to the other party setting forth the specific points in dispute. Any points remaining in dispute twenty (20) days after the giving of such notice may be submitted to arbitration in New York, New York, or Seattle, Washington, whichever the complaining party may choose, to Jams/Endispute, before a single arbitrator appointed in accordance with the arbitra tion rules of Jams/Endispute, modified only as herein ex pressly provided. After the aforesaid twenty (20) days, either party, upon ten (10) days notice to the other, may so submit the points in dispute to arbitration. The arbitrator may enter a default decision against any party who fails to participate in the arbitration proceedings. (a) The decision of the arbitrator on the points in dispute will be final, unappealable and binding, and judgment on the award may be entered in any court having jurisdiction thereof. (b) Except as otherwise provided in this Agreement, the arbitrator will be authorized to apportion its fees and expenses and the reasonable attorney's fees and expenses of any such party as the arbitrator deems appropriate. In the absence of any such apportionment, the fees and expenses of the arbitrator will be borne equally by each party, and each party will bear the fees and expenses of its own attorney. (c) The parties agree that this Section 4 has been included to rapidly and inexpensively resolve any disputes between them with respect to this Agreement, and that this Section shall be grounds for dismissal of any court action commenced by either party with respect to this Agreement, other than with respect to matters for which the Company has sought injunctive relief, and post- arbitration actions seeking to enforce an arbitration award. In the event that any court determines that this arbitration procedure is not binding, or otherwise allows any litigation regarding a dispute, claim or controversy covered by this Agreement to proceed, the parties hereto hereby waive any and all right to a trial by jury in or with respect to such litigation. 5. Separability. All provisions of this Agreement are intended to be severable. In the event any provision or restriction contained herein is held to be invalid or unenforceable in any respect, in whole or in part, such finding shall in no way affect the validity or enforce ability of any other provision of this Agreement. The par ties hereto further agree that any such invalid or un enforceable provision shall be deemed modified so that it shall be enforced to the greatest extent permissible under law, and to the extent that any court of competent jurisdic tion determines any restriction herein to be unreasonable in any respect, such court may limit this Agreement to render it reasonable in the light of the circumstances in which it was entered into and specifically enforce this Agreement as limited. 6.
