(a) Each Indemnified Party shall be entitled to select its own counsel in defense of any action, suit, proceeding or alternative dispute resolution mechanism, whether civil, criminal, administrative, investigative or other (each, a “Claim”) that may cause Indemnifiable Losses to such Indemnified Party. The Company shall advance all reasonable expenses, including attorneys’ fees and all other related costs, expenses and obligations incurred in connection with investigating or defending against a Claim (collectively, the “Defense Expenses”).

(b) If a Claim is asserted by any third party against an Indemnified Party, such Indemnified Party may request the Company to defend the Claim on behalf of the Indemnified Party by a written notice. If the Company fails to defend the Indemnified Party upon such request, a recovery against the Indemnified Party shall be conclusive in its favor against the Company, provided, however, that, if the Company has not received reasonable notice of the Claim or is not allowed to control its defense, judgment against the Indemnified Party shall only constitute presumptive evidence against the Company.

(c) All payments to be made by the Company to an Indemnified Party hereunder shall be made in immediately available funds to a bank account designated by such Indemnified Party. All payments to be made to the Indemnified Party shall be made in U.S. Dollars. The Company covenants and agrees that (i) it has full authority and resources to make any payment hereunder to or for the account of the Company or any Indemnified Party in U.S. Dollars if so required; and (ii) it shall make all payments hereunder irrespective of and without deduction for, any counterclaim, defense, recoupment, or set-off; and (iii) any payment or indemnity hereunder shall include an amount necessary to hold the recipient of such payment or indemnity harmless on an after-Tax basis from all Taxes required to be paid with respect to such payment or indemnity, taking into account any Tax.

(a) It is duly organized and validly existing under the laws of the jurisdiction of its formation and has the corporate power and authority to own and operate its properties, to carry on its business as now conducted and as proposed to be conducted and to perform each of its obligations under this Agreement.

(b) Any corporate action necessary on the part of the Company and its officers, directors and shareholders has been taken for the authorization, execution, and delivery by it of this Agreement and the performance of its obligations hereunder. This Agreement constitutes the valid and legally binding obligation of the Company, enforceable in accordance with the terms hereof, except (i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally, and (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other remedies in the nature of equitable remedies.

(c) The execution, delivery, and performance by the Company of this Agreement requires no Consent of any third party and (i) will not result in any violation of, be in conflict with, or constitute a default under, with or without the passage of time or the giving of notice, any provision of its constitutional documents as in effect at the date hereof, any applicable Law, or any material contract or obligation to which it is a party or by which it is bound, or (ii) accelerate or constitute an event entitling the holder of any indebtedness of the Company to accelerate the maturity of any such indebtedness or to increase the rate of interest presently in effect with respect to such indebtedness, or (iii) result in the creation of any Encumbrance upon any of the properties or assets of the Company.

(d) No breach or default, alleged breach or default, or event which would (with the passage of time, notice or both) constitute a breach or default under any agreement, undertaking or instrument to which the Company is a party or by which the Company may be bound (including, inter alia this Agreement) has occurred, or as a result of this Agreement, or the performance hereof, will occur.

(e) No litigation, arbitration or administrative proceedings are at present current or pending, or to the knowledge of the Company, threatened, which would have a material adverse effect upon the ability of the Company to fulfill its obligations hereunder.

4.1 Binding Effect; Assignment. This Agreement shall be binding upon and shall be enforceable by each party, its successors and permitted assigns. Each Investor shall have the right to assign all or part of its rights under this Agreement to any Person to the extent the Investor transfers any Series C Preferred Shares thereto in.

4.2 Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York, excluding those laws that direct the application of the laws of another jurisdiction.

(a) Any dispute, controversy or claim (each, a “Dispute”) arising out of or relating to this Agreement shall be resolved first through consultation. Such consultation shall begin immediately after one party hereto has delivered to the other party hereto a written request for such consultation.

If any of the members of the arbitral tribunal have not been appointed within thirty (30) days after the Arbitration Notice is given, the relevant appointment shall be made by the Secretary General of the Center.

(c) The arbitration proceedings shall be conducted in English. The arbitration tribunal shall apply the Arbitration Rules of the United Nations Commission on International Trade Law, as in effect at the time of the arbitration. However, if such rules are in conflict with the provisions of this Section 4.3, including the provisions concerning the appointment of arbitrator, the provisions of this Section 4.3 shall prevail.

(d) Each party to the arbitration shall cooperate with each other party to the arbitration in making full disclosure of and providing complete access to all information and documents requested by such other party in connection with such arbitration proceedings, subject only to any confidentiality obligations binding on such party.

(e) The award of the arbitration tribunal shall be final and binding upon the parties, and the prevailing party may apply to a court of competent jurisdiction for enforcement of such award.

(f) The arbitrator shall decide any Dispute submitted by the parties to the arbitration strictly in accordance with the substantive law of the State of New York and shall not apply any other substantive law.

(g) Any party to the Dispute shall be entitled to seek preliminary injunctive relief, if possible, from any court of competent jurisdiction pending the constitution of the arbitral tribunal.

(h) During the course of the arbitration tribunal’s adjudication of the Dispute, this Agreement shall continue to be performed except with respect to the part in dispute and under adjudication.

4.7 Entire Agreement. This Agreement and the documents referred to herein constitute the entire agreement between the parties hereto pertaining to the subject matter hereof, and any and all other written or oral agreements existing between the parties hereto are expressly canceled.

4.8 Severability. If one or more provisions of this Agreement are held to be unenforceable under applicable law, portions of such provisions, or such provisions in their entirety, to the extent necessary, shall be severed from this Agreement and the balance of the Agreement shall be interpreted as if such provision were so excluded and shall be enforceable in accordance with its terms.

4.9 Remedies Cumulative. The rights and remedies available under this Agreement or otherwise available shall be cumulative of all other rights and remedies and may be exercised successively.

4.10 Counterpart Execution. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

4.11 No Third Party Beneficiary. Nothing in this Agreement is intended to confer upon any Person other than the parties hereto and their respective successors and permitted assigns any rights, benefits, or obligations hereunder.

IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of the day and year first written above.
