8 or any of their Affiliates for any act or omission performed or omitted by any of them in good faith (including, without limitation, any act or omission performed or omitted by any of them in reliance upon and in accordance with the opinion or advice of experts, including, without limitation, of legal counsel as to matters of law, of accountants as to matters of accounting, or of investment bankers or appraisers as to matters of valuation), except with respect to (i) any act taken by such Indemnified Party purporting to bind the Corporation that has not been authorized pursuant to these Bylaws or (ii) any act or omission with respect to which such Indemnified Party was grossly negligent or engaged in intentional misconduct. To the extent that, at law, in equity, or otherwise, any Indemnified Party has duties (including fiduciary duties) and liabilities relating thereto to the Corporation or to its stockholders, such Indemnified Party acting under these Bylaws shall not be liable to the Corporation or to its stockholders for its good faith reliance on the provisions of these Bylaws. The provisions of these Bylaws, to the extent that they restrict, modify or eliminate the duties and liabilities of an Indemnified Party otherwise existing at law or in equity, shall replace such other duties and liabilities of such Indemnified Party, to the maximum extent permitted by applicable law. Section 3. Indemnification. (a) To the fullest extent permitted by applicable law, the Corporation shall indemnify and hold harmless and pay all judgments and claims against (i) the Board (ii) each officer of the Corporation, (iii) each director and (iv) each stockholder or their respective Affiliates, officers, directors, employees, shareholders, partners, managers and members (each, an “Indemnified Party”), each of which shall be a third party beneficiary of these Bylaws solely for purposes of this Section 3 of this Article IX from and against any loss or damage incurred by an Indemnified Party or by the Corporation for any act or omission taken or suffered by such Indemnified Party in good faith (including, without limitation, any act or omission taken or suffered by any of them in reliance upon and in accordance with the opinion or advice of experts, including, without limitation, of legal counsel as to matters of law, of accountants as to matters of accounting, or of investment bankers or appraisers as to matters of valuation) in connection with the purpose and business of the Corporation, including costs and reasonable attorneys’ fees and any amount expended in the settlement of any claims or loss or damage, except with respect to (i) any act taken by such Indemnified Party purporting to bind the Corporation that has not been authorized pursuant to these Bylaws or (ii) any act or omission with respect to which such Indemnified Party was grossly negligent or engaged in intentional misconduct. (b) The satisfaction of any indemnification obligation pursuant to Section 3(a) of this Article IX shall be from and limited to Corporation assets (including insurance and any agreements pursuant to which the Corporation, its officers or employees are entitled to indemnification) and the stockholder, in such capacity, shall not be subject to personal liability therefor. (c) Expenses reasonably incurred by an Indemnified Party in defense or settlement of any claim that may be subject to a right of indemnification hereunder shall be advanced by the Corporation prior to the final disposition thereof upon receipt of an undertaking by or on behalf of such Indemnified Party to repay such amount to the extent that it shall be

9 determined upon final adjudication after all possible appeals have been exhausted that such Indemnified Party is not entitled to be indemnified hereunder. (d) The Corporation may purchase and maintain insurance, on behalf of all Indemnified Parties and other Persons against any liability which may be asserted against, or expense which may be incurred by, any such Person in connection with the Corporation’s activities, whether or not the Corporation would have the power to indemnify such Person against such liabilities under the provisions of these Bylaws. (e) Promptly after receipt by an Indemnified Party of notice of the commencement of any investigation, action, suit, arbitration or other proceeding, whether civil or criminal (collectively, “Proceeding”), such Indemnified Party shall, if a claim for indemnification in respect thereof is to be made against the Corporation, give written notice to the Corporation of the commencement of such Proceeding; provided, however, that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Corporation of its obligations under this Section 3, except to the extent that the Corporation is actually prejudiced by such failure to give notice. In case any such Proceeding is brought against an Indemnified Party (other than a derivative suit in right of the Corporation), the Corporation will be entitled to participate in and to assume the defense thereof to the extent that the Corporation may wish, with counsel reasonably satisfactory to such Indemnified Party. After notice from the Corporation to such Indemnified Party of the Corporation’s election to assume the defense of such Proceeding, the Corporation will not be liable for expenses subsequently incurred by such Indemnified Party in connection with the defense thereof. The Corporation will not consent to entry of any judgment or enter into any settlement of such Proceeding that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party a release from all liability in respect of such Proceeding and the related claim. The right to indemnification and the advancement of expenses conferred in this Section 3 of this Article IX shall not be exclusive of any other right which any Person may have or hereafter acquire under any statute, agreement, bylaw, vote of the Board or otherwise. The rights conferred upon any Indemnified Party in Sections 2 and 3 of this Article IX shall be contract rights that vest upon the occurrence or alleged occurrence of any act or omission giving rise to any proceeding or threatened proceeding and such rights shall continue as to any Indemnified Party who has ceased to be manager, director or officer and shall inure to the benefit of such Indemnified Party’s heirs, executors and administrators. Any amendment, alteration or repeal of Sections 2 and 3 of this Article IX that adversely affects any right of any Indemnified Party or its successors shall be prospective only and shall not limit or eliminate any such right with respect to any proceeding involving any occurrence or alleged occurrence of any action or omission to act that took place prior to such amendment, alteration or repeal. Section 5. Continuing Obligation. The provisions of this Article IX shall be deemed to be a contract between the Corporation and each director or officer of the Corporation who serves in such capacity at any time while these Bylaws are in effect, and any repeal or modification thereof shall not affect any rights or obligations then existing with respect to any state of facts then or theretofore existing or any action, suit or proceeding theretofore or thereafter brought based in whole or in part upon any such state of facts.

10 Section 6. Nonexclusive.
