13. Assignment

     Except as set forth in this Section 13, neither this Agreement, nor any of the rights or obligations hereunder, may be assigned, transferred, subcontracted or delegated by a party hereto to any third party (other than a parent or subsidiary under common control with the assigning party), including without limitation, by operation of law or pursuant to a Change of Control (as defined below). Notwithstanding the foregoing, (a) Purchaser may assign this Agreement, and the rights and obligations hereunder, without the prior consent of WAM, in connection with a Change of Control and (b) WAM may assign this Agreement, and the rights and obligations hereunder, without the prior consent of Purchaser, to a third party in connection with a Change of Control; so long as WAM assigns all obligations under this Agreement to any party that succeeds to all or substantially all of WAM’s business. For purposes of this Section 13, “Change of Control” shall mean (i) any sale, lease, exchange or other transfer (in one transaction or series of transactions) of all, or substantially all, of the assets of such party, (ii) any consolidation or merger or other combination of a party in which such party is not the continuing or surviving corporation or pursuant to which shares of such party’s common stock would be converted into cash, securities or other property (other than a merger of such party in which the holders of such party’s common stock immediately prior to the merger hold at least a majority of the outstanding securities of the combined entity), or (iii) any transaction (or series of related transactions) pursuant to which any person (as defined in Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), becomes the beneficial owner (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of 35% or more of such party’s outstanding common stock. Any purported assignment of this Agreement or the rights or obligations of a party under this Agreement in violation of this Section 13 shall be null, void and of no further force or effect. Notwithstanding the foregoing, in the event of an assignment of this Agreement in connection with a Change of Control of Purchaser by a third party [****], no consent by WAM to such assignment shall be required, but WAM may require

the assignee to acknowledge in writing its acceptance of revised and accelerated payment terms under Section 4 of this Agreement following such Change of Control.

14. Rights and Remedies

     All rights and remedies conferred by this Agreement or by law are cumulative and may be exercised singly or concurrently. If any provision of this Agreement is held invalid by any law or regulation of any government or by any court, such invalidity shall not effect the enforceability of any other provisions hereof.

15. Applicable Law

     This Agreement shall be governed by and construed under the laws of the State of New York without regard to its conflicts of law provisions. The exclusive jurisdiction for the resolution of any dispute arising out of this Agreement by mediation, arbitration or suit shall be in New York, New York.

16. Disputes

     The parties agree that any material dispute between the parties relating to this Agreement shall be handled as follows:

16.1 First, the parties will submit the dispute to a panel of two senior executives (Vice-President or more senior) of each party. Either party may initiate this proceeding by notifying the other party in writing pursuant to the notice provisions of Section 12. Within five (5) Days from the date of receipt of the notice, the parties’ executives shall confer (via telephone or in person) in an effort to resolve such dispute (the “First Executive Conference”). The decision of the executives shall be final and binding on the parties. In the event that the executives are unable to resolve such dispute within twenty (20) Days after the First Executive Conference, then the parties shall follow the procedures set forth in Sections 16.2 and 16.3 below. Each party’s executives shall be identified by notice to the other party and may be changed at any time thereafter also by notice to the other party.

16.2 In the event that the First Executive Conference does not resolve the dispute, the parties shall submit the dispute to JAMS, or any other mutually selected mediator (the “Mediator”) for non-binding mediation. The parties will cooperate with the Mediator and with one another in selecting the Mediator (in the case of JAMS, in selecting an individual to mediate from

JAM’s panel of neutrals), and in promptly scheduling the mediation proceedings. The parties covenant that they will participate in the mediation in good faith, and that they will share equally in its costs. All offers, promises, conduct and statements, whether oral or written, made in the course of the mediation by any of the parties, their agents, employees, experts and attorneys, and by the Mediator, are confidential, privileged and inadmissible for any purpose, including impeachment, in any arbitration or other proceeding involving the parties, provided that evidence that is otherwise admissible or discoverable shall not be rendered inadmissible or non-discoverable as a result of its use in the mediation. If the dispute is not resolved within thirty (30) Days from the date of the submission of the dispute to mediation (or such later date as the parties may mutually agree in writing), the dispute shall be submitted to arbitration in accordance with Section 16.3 below. The mediation may continue, if the parties so agree, after the appointment of the arbitrators. Unless otherwise agreed by the parties, the Mediator shall be disqualified from serving as arbitrator in the case. The pendency of a mediation shall not preclude a party from seeking provisional remedies in aid of the arbitration from a court of appropriate jurisdiction, and the parties agree not to defend against any application for provisional relief on the ground that a mediation is pending.

16.3 In the event the parties do not settle the dispute through mediation, the parties will submit the matter(s) to binding arbitration in New York, New York, in accordance with the Commercial Arbitration Rules of the AAA. Each party shall appoint one arbitrator, and the two arbitrators thus appointed will appoint a third arbitrator. The parties shall instruct the arbitrators to make a determination within thirty (30) Days after submission of the dispute to arbitration. Each party shall bear its own arbitration costs and expenses; provided, however, that the arbitrators may modify the allocation of fees, costs and expenses in the award in those cases where fairness dictates other than each party bearing its own fees, costs and expenses. The award shall be final and binding on the parties, and judgment on the award may be entered in and enforced by any court of competent jurisdiction.

17. General

     This Agreement is the complete and entire understanding between the Parties on the subject matter contained herein and supersedes all prior agreements, proposals,

representations, statements, or understandings whether written or oral on this subject between them. The provisions of this Agreement may be amended or waived only by a writing executed by the authorized representatives of the Parties hereto.

     In the event that either Party to this Agreement shall, on any occasion, fail to perform any provision of this Agreement, and the other Party does not enforce that provision, the failure to enforce shall not prevent enforcement of the provision on any other occasion.

     Each Party, including its agents, and employees, is an independent contractor and not an agent or employee of the other. Without limiting the generality of the foregoing, neither Party is authorized to represent or make any commitments on behalf of the other, and both Parties expressly disclaim any liability therefore.

     The headings contained herein are for reference purposes only and shall not in any way effect the meaning or interpretation of this Agreement. This Agreement shall be construed without regard to the identity of the Party who drafted it, and each and every provision of this Agreement shall be construed as though all of the Parties participated equally in the drafting.
