(b)    No Third Party Beneficiaries. This Guarantee is for the sole benefit of the Parties and their permitted assigns and nothing herein expressed or implied shall give or be construed to give to any Person (including their successors and assigns), other than the Parties and such assigns, any rights, benefits, causes of action or remedies with respect to the subject matter or any provision hereof.

(c)    Entire Agreement. This Guarantee and the Confidentiality Agreement contain the entire agreement between the Parties with respect to the subject matter hereof and supersede all prior discussions, correspondence, negotiations, proposed term sheet, agreement, understanding or arrangement, and there are no agreements, understandings, representations or warranties between the Parties relating to such subject matter other than those set forth or referred to in this Guarantee and in the Confidentiality Agreement.

(d)    Heading; Definitions. The section headings contained in this Guarantee are inserted for convenience of reference only and will not affect the meaning or interpretation of this Guarantee.

(e)    Governing Law; Jurisdiction and Forum; Waiver of Jury Trial.

(i)    This Guarantee, and all Actions that may be based upon, arising out of or related to this Guarantee or the transactions contemplated hereby, shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to the conflicts of law rules or principles that would result in the application of the law of any other state.

(ii)    Each of the Parties (A) irrevocably consents to the service of the summons and complaint and any other process with respect to any Action based upon, arising out of or related to this Guarantee or any of the transactions contemplated hereby, on behalf of itself or its property, in accordance withSection 2(f), and (B) subject toSection 2(e)(iii) below, (1) irrevocably and unconditionally consents and submits itself and its property with respect to any such Action to the exclusive general jurisdiction of the Chosen Courts, (2) agrees that it shall not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such Chosen Court, (3) irrevocably and unconditionally agrees that any Action based upon, arising out of or related to this Guarantee or any of the transactions contemplated hereby shall be brought, tried and determined only in the Chosen Courts, (4) waives any objection that it may now or hereafter have to the venue of any such action or proceeding in any such Chosen Court or that any such Action was brought in an inconvenient court and agrees not to plead or claim the same and (5) agrees that it shall not bring any Action based upon, arising out of or related to this Guarantee or any of the transactions contemplated hereby in any court other than the aforesaid Chosen Courts. Each of Guarantor and Purchaser agrees that a final judgment in any Action in such Chosen Court as provided above shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable Law.

(iii)    If, and only if, the Chosen Courts would not have jurisdiction over all or any portion of an Action based upon, arising out of or related to this Guarantee or any of the transactions contemplated hereby (all or such portion of an Action that the Chosen Courts would not have jurisdiction over, an “Arbitration Action”), the Parties agree that the Arbitration Action will be finally settled by binding arbitration conducted under the then current rules fornon-administered arbitration of the International Institute for Conflict Prevention and Resolution (“CPR”, such rules the “CPR Rules”). Any Arbitration Action shall, upon twenty (20) days written notice to the other party (an “Arbitration Notice”), be submitted to CPR arbitration conducted before a panel of three arbitrators in New York, New York. In connection with an Arbitration Action, Guarantor and Purchaser will each promptly (and in any event within fifteen (15) days) after an Arbitration Notice appoint one arbitrator (the “Party-Appointed Arbitrators”), and the Party-Appointed Arbitrators will appoint the third and presiding arbitrator within fourteen (14) days of the appointment of the second arbitrator;provided, that, (A) any arbitrator not timely appointed herein will be appointed under the CPR Rules upon the written demand of any Party to the Arbitration Action, and (B) each such arbitrator must be (1) an attorney with significant

experience in negotiating complex commercial transactions or a judge seated on, or retired from, a U.S. federal court sitting in the Southern District of New York or the Delaware Court of Chancery and (2) neutral and independent of each Party. For the avoidance of doubt, nothing in thisSection 2(e)(iii) shall prevent either Party from seeking interim injunctive relief in the Delaware Court of Chancery to prevent irreparable injury pending appointment of the arbitrators pursuant to thisSection 2(e)(iii). The arbitrators may enter a default decision against any Party who fails to participate in the arbitration proceedings with respect to any Arbitration Action. The decision of the arbitrators 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. The arbitrators will only be authorized to interpret the provisions of this Guarantee, and will not amend, change or add to any such provisions. The Parties and the arbitrators will keep confidential, and will not disclose to any Person, except the Parties’ respective Representatives, or as may be required by applicable Law or any Order of a Governmental Entity of competent jurisdiction, the existence of any Arbitration Action under thisSection 2(e)(iii), the referral of any such Arbitration Action to arbitration or the status or resolution thereof. The initiation of any Arbitration Action pursuant to this Section 2(e)(iii) will toll the applicable statute of limitations for the duration of any such Arbitration Action.

(iv)    EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS GUARANTEE IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS GUARANTEE OR THE TRANSACTIONS CONTEMPLATED HEREBY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (i) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (ii) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (iii) EACH PARTY MAKES THIS WAIVER VOLUNTARILY, AND (iv) EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS GUARANTEE BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THISSECTION 2(E).

(f)    Notices. All notices, requests, claims, demands and other communications under this Guarantee shall be in writing and shall be given (and shall be deemed to have been duly given upon receipt) by delivery in person, by facsimile (having obtained electronic delivery confirmation thereof),e-mail (having obtained electronic delivery confirmation thereof), or upon delivery by registered or certified mail (postage prepaid, return receipt requested) to the other Party as follows:

(k)    Non-Recourse. Notwithstanding anything to the contrary in this Guarantee (but subject to the last sentence of thisSection 2(k)), this Guarantee may only be enforced against, and any claims or causes of action and Actions that may be based on, arise out of or relate to this Guarantee, the transactions contemplated by this Guarantee, or the negotiation, execution or performance of this Guarantee, may only be made against, the Parties, and no former, current or future Affiliates, directors, officers, shareholders, partners, members, attorneys, accountants, agents, Representatives or employees of any Party, or any heirs, successors or permitted assigns of any of the foregoing (each, a “Non-Party”) shall have any liability for any obligations or liabilities of such Party or for any claim (whether in tort, contract or otherwise) based upon, arising out of, or relating to, this Guarantee or the transactions contemplated by this Guarantee or in respect of any representations and warranties made or alleged to be made in connection herewith.
