NOW, THEREFORE, the Member, intending to be legally bound, does hereby constitute the operating agreement of the Company as follows

ARTICLE I.

FORMATION

SECTION 1.1. Formation. The Company was formed on January 1, 2011, and shall be continued pursuant to the terms hereof. The rights and obligations of the Member and the terms and conditions of the Company shall be governed by the Act and this Agreement. To the extent the Act and this Agreement are inconsistent with respect to any subject matter covered in this Agreement, this Agreement shall govern, but only to the extent permitted by law.

SECTION 1.2. Name. The name of the Company is Aurora Technology Development, LLC.

SECTION 1.3. Purposes. The Company is formed for the purpose of engaging in any lawful act or activity for which limited liability companies may be formed under the Act.

SECTION 1.5. Tax Classification; Requirement of Separate Books and Records and Segregation of Assets and Liabilities. Because the Company will have a single Member pursuant to Treasury Regulation Section 301.7701-3, the Company shall be disregarded as an entity separate from its owner for federal income tax purposes until the effective date of any election it may make to change its classification for federal income tax purposes to that of a

corporation by filing IRS Form 8832, Entity Classification Election, or until the Company has more than one Member in which case it would be treated as a partnership for federal income tax purposes (provided that the Company has not elected on IRS Form 8832 to be treated as a corporation). In all events, however, the Company shall keep books and records separate from those of its sole Member and shall at all times segregate and account for all of its assets and liabilities separately from those of its sole Member.

SECTION 1.6. Title to Assets; Transactions. The Company shall keep title to all of its assets in its own name and not in the name of its Member. The Company shall enter into and engage in all transactions in its own name and not in the name of its Member.

SECTION 2.2. Liability of Member. The Member shall not be liable for any debts or losses of capital or profits of the Company or be required to contribute or lend funds to the Company.

ARTICLE III.

DISTRIBUTIONS

SECTION 3.1. Distributions.

The Managers shall be free to delegate management authority to officers of the Company appointed in writing by the Managers.

SECTION 4.2. Limitation of Liability; Indemnification. Notwithstanding any other provision to the contrary contained in this Agreement, no Manager, Member or officer shall be liable, responsible, or accountable in damages or otherwise to the Company or to any Member or assignee of a Member for any loss, damage, cost, liability, or expense incurred by reason of or caused by any act or omission performed or omitted by such Manager, Member or officer, whether alleged to be based upon or arising from errors in judgment, negligence, or breach of duty (including alleged breach of any duty of care or duty of loyalty or other fiduciary duty), except for (a) acts or omissions the Manager, Member or officer knew at the time of the acts or omissions were clearly in conflict with the interest of the Company, (b) any transaction from which the Manager, Member or officer derived an improper personal benefit, (c) a willful breach of this Agreement, or (d) gross negligence, recklessness, willful misconduct, or knowing violation of law.

The Manager may, but is not required to, provide for the limitation of liability of Persons to whom the Manager may delegate management authority which limitation of liability must be in writing in order to be effective.

SECTION 4.3. Indemnity.

(a) Every Person (and the heirs, executors and administrators of such Person) who is or was a Member, Manager or officer of the Company shall be indemnified by the Company against all judgments, payments in settlement (whether or not approved by court), fines, penalties and other reasonable costs and expenses (including fees and disbursements of counsel) imposed upon or incurred by such Person in connection with or resulting from any action, suit, proceeding, investigation or claim, whether civil, criminal, administrative, legislative or other (including any criminal action, suit or proceeding in which such person enters a plea of guilty or nolo contendere or its equivalent), or any appeal relating thereto which is brought or threatened by any other person, governmental authority or instrumentality (herein called a “third- party action”) and in which such person is made a party or is otherwise involved by reason of his being or having been such Member, Manager or officer or by reason of any action or omission, or alleged action or omission, by such person in his capacity as such Member, Manager or officer if either (a) such person is wholly successful, on the merits or otherwise, in defending such third- party action or (b) in the judgment of a court of competent jurisdiction or, in the absence of such determination, in the judgment of the Member, such person acted in good faith and in what he reasonably believed to be the best interest of the Company and, in addition, in any criminal action, had no reasonable cause to believe that his conduct was unlawful. In case such person is successful, on the merits or otherwise, in defending part of such action, or, in the judgment of such a court or the Member, has met the applicable standard of conduct specified in the preceding sentence with respect to part of such action, he shall be indemnified by the Company against the judgments, settlement payments, fines, penalties and other costs and expenses attributable to such part of such action. The foregoing rights of indemnification shall be in addition to any rights to which any such Member, Manager or officer may otherwise be entitled.

(b) In any case in which, in the judgment of the Member, any such Member, Manager or officer will be entitled to indemnification under the foregoing provisions of this Section 4.3, such amounts as it deems necessary to cover the reasonable costs and expenses incurred by such Person in connection with the action, suit, proceeding, investigation or claim prior to final disposition thereof shall be advanced to such Person upon receipt of an undertaking by or on behalf of such Person to repay such amounts if it is ultimately determined that he is not so entitled to indemnification.
