      4.  Reclassifications . Without the affirmative vote of the holders of Class A Common Stock representing a majority of the voting power of the outstanding shares of Class A Common Stock, voting separately as a single class, and the affirmative vote of the holders of Class B Common Stock representing a majority of the voting power of the outstanding shares of Class B Common Stock, voting separately as a single class, neither the shares of Class A Common Stock nor the shares of Class B Common Stock may be subdivided, combined, reclassified or otherwise changed unless concurrently the shares of the other class of Common Stock are subdivided, combined, reclassified or otherwise changed in the same proportion and in the same manner. For purposes of the preceding sentence, any reclassification or other change of Class A Common Stock or Class B Common Stock into (i) Voting Securities or (ii) Exchangeable Securities shall be deemed undertaken in the same proportion and in the same manner as shares of the other class of Common Stock if, and only if:

     (b) In the case of a reclassification or other change into Exchangeable Securities, either (x) such reclassification or other change is identical and approved by the vote of the holders of Class B Common Stock representing a majority of the voting power of the outstanding shares of Class B Common Stock; or (y) (i) such Exchangeable Securities are identical in all respects except as provided in subsections (ii), (iii) and (iv) of this section A(4)(b) of Article FOURTH; (ii) the voting rights of each Voting Security underlying the Exchangeable Security to which the Class A Common Stock has been reclassified or otherwise changed are substantially similar to those of the Class A Common Stock; (iii) the voting rights of each Voting Security underlying the Exchangeable Security to which the Class B Common Stock has been reclassified or otherwise changed are substantially similar to those of the Class B Common Stock; (iv) each Voting Security underlying the Exchangeable Security to which the Class B Common Stock has been reclassified or otherwise changed is convertible into each Voting Security underlying the Exchangeable Security to which the Class A Common Stock has been reclassified or otherwise changed upon terms and conditions that are substantially similar to the terms and conditions

applicable to the conversion of Class B Common Stock into Class A Common Stock; and (v) the number of such Exchangeable Securities to which the Class A Common Stock has been reclassified or otherwise changed is equal to the number of such Exchangeable Securities to which the Class B Common Stock has been reclassified or otherwise changed.

      6.  Conversion Rights .

     (a) Voluntary Conversion . Each share of Class B Common Stock is convertible into one share of Class A Common Stock at any time at the option of the holder. Such right shall be exercised by the surrender of the certificate or certificates representing the shares of Class B Common Stock to be converted to the Corporation at any time during normal business hours at the principal executive offices of the Corporation or at the offices of the Corporation’s transfer agent (the “Transfer Agent”), accompanied by a written notice from the holder of such shares stating that such holder desires to convert such shares, or a stated number of the shares represented by such certificate of certificates, into an equal number of shares of Class A Common Stock, and, if so required by the Corporation or the Transfer Agent, by instruments of transfer in form satisfactory to the Corporation and the Transfer Agent, duly executed by such holder or such holder’s duly authorized attorney, and transfer tax stamps or funds therefor, if required.

     (b) Automatic Conversion .

     (i) As used in this Section A.6(b) and in Article NINTH, the following terms have the following meanings:

     (1) “Automatic Conversion Date” shall mean:

     (A) the first date upon which one of the following events has occurred with respect to each Founder:

     (I) such Founder has died; or

     (II) such Founder has been judicially declared legally incompetent, or a conservator, receiver or custodian has been appointed to supervise, oversee or otherwise control the financial affairs of such Founder; or

     (III) such Founder has ceased to be affiliated with the Corporation as an employee, director or consultant; or

     (B) the first date following the first issuance of Class B Common Stock upon which the number of outstanding shares of Class B Common Stock is less than 20% of the number of outstanding shares of Common Stock.

     (2) “Founder” shall mean each of Sachiko Kuno, Ph.D. and Ryuji Ueno, M.D., Ph.D., Ph.D., individually.

     (3) “Person” shall mean an individual, a partnership, a limited liability company, a corporation, an association, a joint stock company, a trust, a joint venture, an unincorporated organization or a governmental entity or any department, agency or political subdivision thereof.

     (4) “Permitted Transferee” shall mean a trust of which either or both Founders are the sole trustees or otherwise control all decisions regarding the voting of any shares of Class B Common Stock held by such trust, provided that such trust is established solely for the benefit of (A) either or both Founders, (B) either Founder’s children, parents, uncles, aunts, siblings and descendents of such siblings or grandchildren and descendents of such grandchildren, (C) the estates of any of the foregoing individuals and/or (D) charitable, educational, scientific, religious or literary purposes.

     (5) “S&R” shall mean S&R Holdings, LLC, a limited liability company wholly owned by the Founders, which holds all of the outstanding shares of Class B Common Stock at the time of the filing of this Restated Certificate of Incorporation.

     (6) “Transfer” shall mean the sale, assignment, transfer, gift, pledge or hypothecation or other disposition, whether direct or indirect, whether voluntary or involuntary, of Class B Common Stock to any Person. Notwithstanding the foregoing, the following shall not constitute a “Transfer”: (A) the sale, assignment, transfer, pledge or hypothecation or other disposition in a bona fide financing transaction of any derivative instrument that derives its value from underlying shares of Class B Common Stock, (B) a transfer to any Permitted Transferee, provided that any subsequent failure of the transferee to remain a Permitted Transferee (for example, because neither Founder any longer controls all decisions regarding the voting of the shares of Class B Common Stock held by such transferee) shall be a “Transfer,” (C) a transfer to either Founder individually, and (D) any pledge of shares of Class B Common Stock pursuant to the grant of a bona fide pledge of or security interest in such shares (the “Pledged Shares”) as collateral security for indebtedness due to the pledgee, provided that a “Transfer” shall occur five business days (such date, the “Foreclosure Transfer Date”) after a foreclosure or similar event (a “Foreclosure Event”) by the pledgee with respect to the Pledged Shares unless, prior to the Foreclosure Transfer Date, the Pledged Shares are returned to the pledgor (a “Return”), and further provided that, during the period of time between a Foreclosure Event and the earlier of a Return or the Foreclosure Transfer Date, irrespective of any other provisions of this Certificate of Incorporation, each Pledged Share shall, to the fullest extent permitted by law, be entitled to one vote. Without limiting the generality of the foregoing, a “Transfer” shall be deemed to have occurred with respect to all shares of Class B Common Stock held by S&R at such time as either (I) the Founders together hold less than 50% of the voting interests or less than 50% of the economic interests in S&R or (II) the power to make any decisions regarding the voting or disposition of the shares of Class B Common Stock held by S&R is held by any Person other than a Founder.

     (ii) Immediately upon the occurrence of a Transfer of shares of Class B

Common Stock, and without any action on the part of any stockholder whose shares are subject to automatic conversion hereunder, the Corporation or any other Person, such shares shall be deemed converted into the same number of shares of Class A Common Stock. From and after the time of the Transfer, any such certificates for the relevant shares of Class B Common Stock shall no longer represent shares of Class B Common Stock but instead shall represent shares of Class A Common Stock and the right to have registered in the name of the transferee or owner of such stock the shares of Class A Common Stock issuable to such transferee or owner as a result of such conversion. The Class A Common Stock issuable upon any such conversion shall be so registered and the certificates with respect to such stock shall be issued by the Corporation upon the surrender of the certificates that represent the relevant shares of Class B Common Stock immediately prior to the Transfer, duly endorsed to the Corporation or in blank or accompanied by proper instruments of transfer to the Corporation or in blank (such endorsements or instruments of transfer to be in form satisfactory to the Corporation).

     (iii) Immediately prior to the close of business on the Automatic Conversion Date, all outstanding shares of Class B Common Stock, if any, shall be converted automatically into a like number of shares of Class A Common Stock, without any action on the part of S&R, the Founders, Permitted Transferees, the Corporation or any other Person. From and after such time, any certificates for the relevant shares of Class B Common Stock shall no longer represent shares of Class B Common Stock but instead shall represent shares of Class A Common Stock and the right to have registered in the name of the registered holder of such stock the shares of Class A Common Stock issuable to such holder as a result of such conversion. The Class A Common Stock issuable upon any such conversion shall be so registered and the certificates with respect to such stock shall be issued by the Corporation upon the surrender of the certificates that represent the relevant shares of Class B Common Stock immediately prior to the conversion.

      7.  Unconverted Shares . If less than all of the shares of Class B Common Stock evidenced by a certificate surrendered to the Corporation (in accordance with such procedures as the Board of Directors may determine) are converted, the Corporation shall execute and deliver to or upon the written order of the holder of such certificate a new certificate evidencing the number of shares of Class B Common Stock which are not converted without charge to the holder.

      8.  Reservation . The Corporation hereby reserves, and shall at all times reserve and keep available, out of its authorized and unissued shares of Class A Common Stock, for the purposes of effecting conversions, such number of duly authorized shares of Class A Common Stock as shall from time to time be sufficient to effect the conversion of all outstanding shares of Class B Common Stock. The Corporation covenants that all the shares of Class A Common Stock so issuable shall, when so issued, be duly and validly issued, fully paid and nonassessable. The Corporation shall take all such action as may be necessary to ensure that all such shares of Class A Common Stock may be so issued without violation of any applicable law or regulation.

      9. Merger . The affirmative vote of the holders of Class A Common Stock representing a majority of the voting power of the outstanding shares of Class A Common Stock, voting separately as a single class, and the affirmative vote of the holders of Class B Common Stock representing a majority of the voting power of the outstanding shares of Class B Common Stock, voting separately as a single class, shall be required to approve any merger or consolidation of the Corporation (whether or not the Corporation is the surviving entity) unless, upon the merger or consolidation, holders of each class of Common Stock will be entitled to receive equal per share payments or distributions. Without limiting the circumstances in which the holders of each class of Common Stock may be deemed to have received

equal per share payments or distributions, for purposes of the preceding sentence, holders of each class of Common Stock will be deemed to have received equal per share payments or distributions of (i) voting securities of the Corporation or any other entity (“ Merger Voting Securities ”) or (ii) securities convertible into, or exchangeable for, Merger Voting Securities (“ Merger Exchangeable Securities ”) if:

     (a) With respect to Merger Voting Securities, (i) the Merger Voting Securities paid to holders of Class A Common Stock and Class B Common Stock are identical in all respects except as provided in subsections (ii), (iii) and (iv) of this Section A(9)(a) of Article FOURTH; (ii) the voting rights of the Merger Voting Security paid to the holders of Class A Common Stock are substantially similar to those of the Class A Common Stock; (iii) the voting rights of the Merger Voting Security paid to the holders of Class B Common Stock are substantially similar to those of the Class B Common Stock; (iv) the Merger Voting Security paid to the holders of Class B Common Stock is convertible into the Merger Voting Security paid to the holders of Class A Common Stock upon terms and conditions that are substantially similar to the terms and conditions applicable to the conversion of Class B Common Stock into Class A Common Stock; and (v) the number of Merger Voting Securities paid on each share of Class A Common Stock pursuant to such merger or consolidation is equal to the number of Merger Voting Securities paid on each share of Class B Common Stock pursuant to such merger or consolidation; and

     (b) With respect to Merger Exchangeable Securities, (i) the Merger Exchangeable Securities paid to holders of Class A Common Stock and Class B Common Stock are identical in all respects except as provided in subsections (ii), (iii) and (iv) of this Section A(9)(b) of Article FOURTH; (ii) the voting rights of each Merger Voting Security underlying the Merger Exchangeable Security paid to the holders of Class A Common Stock are substantially similar to those of the Class A Common Stock; (iii) the voting rights of each Merger Voting Security underlying the Merger Exchangeable Security paid to the holders of Class B Common Stock are substantially similar to those of the Class B Common Stock; (iv) each Merger Voting Security underlying the Merger Exchangeable Security paid to the holders of Class B Common Stock is convertible into each Merger Voting Security underlying the Merger Exchangeable Security paid to the holders of Class A Common Stock upon terms and conditions that are substantially similar to the terms and conditions applicable to the conversion of Class B Common Stock into Class A Common Stock; and (v) the number of Merger Exchangeable Securities paid on each share of Class A Common Stock pursuant to such merger or consolidation is equal to the number of Merger Exchangeable Securities paid on each share of Class B Common Stock pursuant to such merger or consolidation.

      10.  Issuance of Class B Common Stock . Except in connection with the establishment of the Corporation as a holding company of Sucampo Pharmaceuticals, Inc. (“ SPI ”) as contemplated by Section 251(g) of the General Corporation Law of Delaware and the conversion of shares of Class B Common Stock of SPI into shares of Class B Common Stock, the Corporation shall not issue or sell any shares of Class B Common Stock or any securities (including, without limitation, any rights, options, warrants or other securities) convertible, exchangeable or exercisable into shares of Class B Common Stock to any person or entity. Notwithstanding the foregoing, the Corporation may issue shares of Class B Common Stock in respect of stock splits, stock dividends, subdivisions, reclassifications or similar transactions with respect to the Class B Common Stock.

      11.  Determinations of “Substantially Similar” . For purposes of Sections (A)(3), (A)(4), and (A)(9) of this Article FOURTH, the Board of Directors shall have the power and authority to make all determinations regarding whether or not a characteristic of a security is “substantially similar” to that of another security. All such determinations made by the Board of Directors in good faith shall be final, conclusive and binding.

      12.  Amendments to Section . Notwithstanding any other provision of law, this Certificate of Incorporation or the Bylaws of the Corporation, and notwithstanding the fact that a lesser percentage may be specified by law, the affirmative vote of the holders of Class A Common Stock representing at least 75% of the voting power of the outstanding shares of Class A Common Stock, voting separately as a single class, and the affirmative vote of the holders of Class B Common Stock representing at least 75% of the voting power of the outstanding shares of Class B Common Stock, voting separately as a single class, shall be required to amend or repeal, or to adopt any provision inconsistent with, this Section A of this Article FOURTH.

B. PREFERRED STOCK .

     Preferred Stock may be issued from time to time in one or more series, each of such series to have such terms as stated or expressed herein and in the resolution or resolutions providing for the issue of such series adopted by the Board of Directors as hereinafter provided. Any shares of Preferred Stock which may be redeemed, purchased or acquired by the Corporation may be reissued except as otherwise provided by law.

     Authority is hereby expressly granted to the Board of Directors from time to time to issue the Preferred Stock in one or more series, and in connection with the creation of any such series, by resolution or resolutions providing for the issuance of the shares thereof, to determine and fix the number of shares of such series and such voting powers, full or limited, or no voting powers, and such designations, preferences and relative participating, optional or other special rights, and qualifications, limitations or restrictions thereof, including without limitation thereof, dividend rights, conversion rights, redemption privileges and liquidation preferences, as shall be stated and expressed in such resolutions, all to the full extent now or hereafter permitted by the General Corporation Law of Delaware. Without limiting the generality of the foregoing, the resolutions providing for issuance of any series of Preferred Stock may provide that such series shall be superior or rank equally or be junior to the Preferred Stock of any other series to the extent permitted by law.

     The number of authorized shares of Preferred Stock may be increased or decreased (but not below the number of shares then outstanding) by the affirmative vote of the holders of capital stock representing a majority of the votes entitled to be cast irrespective of the provisions of Section 242(b)(2) of the General Corporation Law of Delaware.

      FIFTH: Except as otherwise provided herein, the Corporation reserves the right to amend, alter, change or repeal any provision contained in this Certificate of Incorporation, in the manner now or hereafter prescribed by statute and this Certificate of Incorporation, and all rights conferred upon stockholders herein are granted subject to this reservation.

      SIXTH: In furtherance and not in limitation of the powers conferred upon it by the laws of the State of Delaware, and subject to the terms of any series of Preferred Stock, the Board of Directors shall have the power to adopt, amend, alter or repeal the Corporation’s Bylaws; provided, however , that until the Automatic Conversion Date, the Board of Directors shall not adopt, amend, alter or repeal the Corporation’s Bylaws without, as to each such adoption, amendment, alteration, or repeal, the affirmative vote of the holders of Class B Common Stock representing a majority of the voting power of the outstanding Class B Common Stock. The affirmative vote of a majority of the directors present at any regular or special meeting of the Board of Directors at which a quorum is present shall be required to adopt, amend, alter or repeal the Corporation’s Bylaws. The Corporation’s Bylaws also may be adopted, amended, altered or repealed by the affirmative vote of the holders of capital stock representing at least 75% of the voting power of all outstanding stock entitled to vote in any annual election of directors, in

addition to any other vote required by this Certificate of Incorporation. Notwithstanding any other provisions of law, this Certificate of Incorporation or the Bylaws of the Corporation, and notwithstanding the fact that a lesser percentage may be specified by law, the affirmative vote of the holders of capital stock representing at least 75% of the voting power of all outstanding stock entitled to vote in any annual election of directors shall be required to amend or repeal, or to adopt any provision inconsistent with, this Article SIXTH.

No amendment to or repeal of this provision shall apply to or have any effect on the liability or alleged liability of any director of the Corporation for or with respect to any acts or omissions of such director occurring prior to such amendment or repeal.

      EIGHTH: The Corporation shall provide indemnification and advancement of expenses as follows:

      1.  Actions, Suits and Proceedings Other than by or in the Right of the Corporation . The Corporation shall indemnify each person who was or is a party or threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the Corporation) by reason of the fact that he or she is or was, or has agreed to become, a director or officer of the Corporation, or is or was serving, or has agreed to serve, at the request of the Corporation, as a director, officer, partner, employee or trustee of, or in a similar capacity with, another corporation, partnership, joint venture, trust or other enterprise (including any employee benefit plan) (all such persons being referred to hereafter as an “Indemnitee”), or by reason of any action alleged to have been taken or omitted in such capacity, against all expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by or on behalf of Indemnitee in connection with such action, suit or proceeding and any appeal therefrom, if Indemnitee acted in good faith and in a manner which Indemnitee reasonably believed to be in, or not opposed to, the best interests of the Corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that Indemnitee did not act in good faith and in a manner which Indemnitee reasonably believed to be in, or not opposed to, the best interests of the Corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that his or her conduct was unlawful.

      2. Actions or Suits by or in the Right of the Corporation . The Corporation shall indemnify any Indemnitee who was or is a party to or threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the Corporation to procure a judgment in its favor by reason of the fact that Indemnitee is or was, or has agreed to become, a director or officer of the Corporation, or is or was serving, or has agreed to serve, at the request of the Corporation, as a director, officer, partner, employee or trustee of, or in a similar capacity with, another corporation, partnership, joint venture, trust or other enterprise (including any employee benefit plan), or by reason of any action alleged to have been taken or omitted in such capacity, against all expenses (including attorneys’ fees) and, to the extent permitted by law, amounts paid in settlement actually and reasonably incurred by or on behalf of Indemnitee in connection with such action, suit or proceeding and any appeal therefrom, if Indemnitee acted in good faith and in a manner which Indemnitee reasonably believed to be in, or not opposed to, the best interests of the Corporation, except that no indemnification shall be made under this Section 2 in respect of any claim, issue or matter as to which Indemnitee shall have been adjudged to be

liable to the Corporation, unless, and only to the extent, that the Court of Chancery of Delaware, or the court in which such action or suit was brought, shall determine upon application that, despite the adjudication of such liability but in view of all the circumstances of the case, Indemnitee is fairly and reasonably entitled to indemnity for such expenses (including attorneys’ fees) which the Court of Chancery of Delaware, or the court in which such action or suit was brought, shall deem proper.

      3.  Indemnification for Expenses of Successful Party . Notwithstanding any other provisions of this Article, to the extent that an Indemnitee has been successful, on the merits or otherwise, in defense of any action, suit or proceeding referred to in Sections 1 and 2 of this Article EIGHTH, or in defense of any claim, issue or matter therein, or on appeal from any such action, suit or proceeding, Indemnitee shall be indemnified against all expenses (including attorneys’ fees) actually and reasonably incurred by or on behalf of Indemnitee in connection therewith. Without limiting the foregoing, if any action, suit or proceeding is disposed of, on the merits or otherwise (including a disposition without prejudice), without (i) the disposition being adverse to Indemnitee, (ii) an adjudication that Indemnitee was liable to the Corporation, (iii) a plea of guilty or nolo contendere by Indemnitee, (iv) an adjudication that Indemnitee did not act in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Corporation, and (v) with respect to any criminal proceeding, an adjudication that Indemnitee had reasonable cause to believe his conduct was unlawful, Indemnitee shall be considered for the purposes hereof to have been wholly successful with respect thereto.

      4.  Notification and Defense of Claim . As a condition precedent to an Indemnitee’s right to be indemnified pursuant to Sections 1, 2 or 3 of this Article EIGHTH, or to receive advancement of expenses pursuant to Section 5 of this Article EIGHTH, such Indemnitee must notify the Corporation in writing as soon as practicable of any action, suit, proceeding or investigation involving such Indemnitee for which indemnity or advancement of expenses will or could be sought. With respect to any action, suit, proceeding or investigation of which the Corporation is so notified, the Corporation will be entitled to participate therein at its own expense and/or to assume the defense thereof at its own expense, with legal counsel reasonably acceptable to Indemnitee. After notice from the Corporation to Indemnitee of its election so to assume such defense, the Corporation shall not be liable to Indemnitee for any legal or other expenses subsequently incurred by Indemnitee in connection with such action, suit, proceeding or investigation, other than as provided below in this Section 4. Indemnitee shall have the right to employ his or her own counsel in connection with such action, suit, proceeding or investigation, but the fees and expenses of such counsel incurred after notice from the Corporation of its assumption of the defense thereof shall be at the expense of Indemnitee unless (i) the employment of counsel by Indemnitee has been authorized by the Corporation, (ii) counsel to Indemnitee shall have reasonably concluded that there may be a conflict of interest or position on any significant issue between the Corporation and Indemnitee in the conduct of the defense of such action, suit, proceeding or investigation or (iii) the Corporation shall not in fact have employed counsel to assume the defense of such action, suit, proceeding or investigation, in each of which cases the fees and expenses of counsel for Indemnitee shall be at the expense of the Corporation, except as otherwise expressly provided by this Article. The Corporation shall not be entitled, without the consent of Indemnitee, to assume the defense of any claim brought by or in the right of the Corporation or as to which counsel for Indemnitee shall have reasonably made the conclusion provided for in clause (ii) of the preceding sentence. The Corporation shall not be required to indemnify Indemnitee under this Article EIGHTH for any amounts paid in settlement of any action, suit, proceeding or investigation effected without its written consent. The Corporation shall not settle any action, suit, proceeding or investigation in any manner which would impose any penalty or limitation on Indemnitee without Indemnitee’s written consent. Neither the Corporation nor Indemnitee will unreasonably withhold or delay its consent to any proposed settlement.

      5. Advance of Expenses . Subject to the provisions of Sections 4 and 6 of this Article EIGHTH, any expenses (including attorneys’ fees) incurred by or on behalf of Indemnitee in defending an

action, suit, proceeding or investigation or any appeal therefrom shall be paid by the Corporation in advance of the final disposition of such matter; provided , however , that the payment of such expenses incurred by or on behalf of Indemnitee in advance of the final disposition of such matter shall be made only upon receipt of an undertaking by or on behalf of Indemnitee to repay all amounts so advanced in the event that it shall ultimately be determined that Indemnitee is not entitled to be indemnified by the Corporation as authorized in this Article; and further provided that no such advancement of expenses shall be made under this Article EIGHTH if it is determined (in the manner described in Section 6) that (i) Indemnitee did not act in good faith and in a manner he reasonably believed to be in, or not opposed to, the best interests of the Corporation, or (ii) with respect to any criminal action or proceeding, Indemnitee had reasonable cause to believe his conduct was unlawful. Such undertaking shall be accepted without reference to the financial ability of Indemnitee to make such repayment.

      6.  Procedure for Indemnification and Advance of Expenses . In order to obtain indemnification or advancement of expenses pursuant to Sections 1, 2, 3 or 5 of this Article EIGHTH, an Indemnitee shall submit to the Corporation a written request. Any such advancement of expenses shall be made promptly, and in any event within 30 days after receipt by the Corporation of the written request of Indemnitee, unless (i) the Corporation has assumed the defense pursuant to Section 4 of this Article EIGHTH (and none of the circumstances described in Section 4 of this Article EIGHTH that would nonetheless entitle the Indemnitee to indemnification or an advancement for the fees and expenses of separate counsel have occurred), or (ii) the Corporation determines within such 30 day period that Indemnitee did not meet the applicable standard of conduct set forth in Sections 1, 2 or 5 of this Article EIGHTH, as the case may be. Any such indemnification, unless ordered by a court, shall be made with respect to requests under Section 1 or 2 only as authorized in the specific case upon a determination by the Corporation that the indemnification of Indemnitee is proper because Indemnitee has met the applicable standard of conduct set forth in Section 1 or 2, as the case may be. Such determination shall be made in each instance (a) by a majority vote of the directors of the Corporation who are not at that time parties to the action, suit or proceeding in question (“disinterested directors”), whether or not a quorum, (b) by a committee of disinterested directors designated by majority vote of disinterested directors, whether or not a quorum, (c) if there are no disinterested directors, or if the disinterested directors so direct, by independent legal counsel (who may, to the extent permitted by law, be regular legal counsel to the Corporation) in a written opinion, or (d) by the stockholders of the Corporation.

      7.  Remedies . The right to indemnification or advancement of expenses as granted by this Article shall be enforceable by Indemnitee in any court of competent jurisdiction. Neither the failure of the Corporation to have made a determination prior to the commencement of such action that indemnification is proper in the circumstances because Indemnitee has met the applicable standard of conduct, nor an actual determination by the Corporation pursuant to Section 6 of this Article EIGHTH that Indemnitee has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that Indemnitee has not met the applicable standard of conduct. Indemnitee’s expenses (including attorneys’ fees) reasonably incurred in connection with successfully establishing Indemnitee’s right to advancement of expenses or indemnification, in whole or in part, in any such proceeding shall also be indemnified by the Corporation.

      8. Limitations . Notwithstanding anything to the contrary in this Article, except as set forth in Section 7 of this Article EIGHTH, the Corporation shall not indemnify or advance expenses to an Indemnitee pursuant to this Article EIGHTH in connection with a proceeding (or part thereof) initiated by such Indemnitee unless the initiation thereof was approved by the Board of Directors. Notwithstanding anything to the contrary in this Article, the Corporation shall not indemnify or advance expenses to an Indemnitee to the extent such Indemnitee is reimbursed or paid expenses from the proceeds of insurance, and in the event the Corporation makes any indemnification payments or advancement of expenses to an Indemnitee and such Indemnitee is subsequently reimbursed from the proceeds of insurance, such

Indemnitee shall promptly refund indemnification payments or advancement of expenses to the Corporation to the extent of such insurance reimbursement.

      9.  Subsequent Amendment . No amendment, termination or repeal of this Article or of the relevant provisions of the General Corporation Law of Delaware or any other applicable laws shall affect or diminish in any way the rights of any Indemnitee to indemnification or advancement of expenses under the provisions hereof with respect to any action, suit, proceeding or investigation arising out of or relating to any actions, transactions or facts occurring prior to the final adoption of such amendment, termination or repeal.

      10.  Other Rights . The indemnification and advancement of expenses provided by this Article shall not be deemed exclusive of any other rights to which an Indemnitee seeking indemnification or advancement of expenses may be entitled under any law (common or statutory), agreement or vote of stockholders or disinterested directors or otherwise, both as to action in Indemnitee’s official capacity and as to action in any other capacity while holding office for the Corporation, and shall continue as to an Indemnitee who has ceased to be a director or officer, and shall inure to the benefit of the estate, heirs, executors and administrators of Indemnitee. Nothing contained in this Article shall be deemed to prohibit, and the Corporation is specifically authorized to enter into, agreements with officers and directors providing indemnification and advancement rights and procedures different from those set forth in this Article. In addition, the Corporation may, to the extent authorized from time to time by its Board of Directors, grant indemnification and advancement rights to other employees or agents of the Corporation or other persons serving the Corporation and such rights may be equivalent to, or greater or less than, those set forth in this Article.

      11.  Partial Indemnification and Advance of Expenses . If an Indemnitee is entitled under any provision of this Article to indemnification or advancement of expenses by the Corporation for some or a portion of the expenses (including attorneys’ fees), judgments, fines or amounts paid in settlement actually and reasonably incurred by or on behalf of Indemnitee in connection with any action, suit, proceeding or investigation and any appeal therefrom but not, however, for the total amount thereof, the Corporation shall nevertheless indemnify or advance expenses to Indemnitee for the portion of such expenses (including attorneys’ fees), judgments, fines or amounts paid in settlement to which Indemnitee is entitled.

      12.  Insurance . The Corporation may purchase and maintain insurance, at its expense, to protect itself and any director, officer, employee or agent of the Corporation or another corporation, partnership, joint venture, trust or other enterprise (including any employee benefit plan) against any expense, liability or loss incurred by him in any such capacity, or arising out of his status as such, whether or not the Corporation would have the power to indemnify such person against such expense, liability or loss under the General Corporation Law of Delaware.

      13.  Savings Clause . If this Article or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the Corporation shall nevertheless indemnify each Indemnitee as to any expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement in connection with any action, suit, proceeding or investigation, whether civil, criminal or administrative, including an action by or in the right of the Corporation, to the fullest extent permitted by any applicable portion of this Article that shall not have been invalidated and to the fullest extent permitted by applicable law.

      14.  Definitions . Terms used herein and defined in Section 145(h) and Section 145(i) of the General Corporation Law of Delaware shall have the respective meanings assigned to such terms in such Section 145(h) and Section 145(i).

      TENTH: Stockholders of the Corporation may not take any action by written consent in lieu of a meeting; provided, however , that until the Automatic Conversion Date, any action required or permitted to be taken at any annual or special meeting of stockholders of the Corporation may be taken without a meeting, without prior notice and without a vote, if a consent in writing, setting forth the action so taken, is signed by the holders of shares of capital stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote on such action were present and voted. Notwithstanding any other provisions of law, this Certificate of Incorporation or the Bylaws of the Corporation, and notwithstanding the fact that a lesser percentage may be specified by law, the affirmative vote of the holders of capital stock representing at least 75% of the votes which all the stockholders would be entitled to cast in any annual election of directors shall be required to amend or repeal, or to adopt any provision inconsistent with, this Article TENTH.

Except to the extent inconsistent with such rules, regulations and procedures as adopted by the Board of Directors, the chairman of any meeting of stockholders shall have the right and authority to prescribe such rules, regulations and procedures and to do all such acts as, in the judgment of such chairman, are appropriate for the proper conduct of the meeting. Such rules, regulations or procedures, whether adopted by the Board of Directors or prescribed by the chairman of the meeting, may include, without limitation, the following: (i) the establishment of an agenda or order of business for the meeting; (ii) rules and procedures for maintaining order at the meeting and the safety of those present; (iii) limitations on attendance at or participation in the meeting to stockholders of record of the corporation, their duly authorized and constituted proxies or such other persons as shall be determined; (iv) restrictions on entry to the meeting after the time fixed for the commencement thereof; and (v) limitations on the time allotted to questions or comments by participants.

     (d) In advance of any meeting of stockholders, the Board of Directors, the Chairman of the Board, the Chief Executive Officer or the President shall appoint one or more inspectors of election to act at the meeting and make a written report thereof.

The inspector shall have the duties prescribed by law and shall take charge of the polls and, when the vote in completed, shall make a certificate of the result of the vote taken and of such other facts as may be required by law.

      1.13 Consent Solicitation.

     (a) Until the Automatic Conversion Date (as that term is defined in the Certificate of Incorporation), any action required or permitted to be taken at any annual or special meeting of stockholders of the Corporation may be taken without a meeting, without prior notice and without a vote, if a consent in writing, setting forth the action so taken, is

signed by the holders of outstanding shares of capital stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote on such action were present and voted.

     (b) In order that the corporation may determine the stockholders entitled to consent to corporate action in writing without a meeting, the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors, and which date shall not be more than 10 days after the date upon which the resolution fixing the record date is adopted by the Board of Directors. Any stockholder of record seeking to have the stockholders authorize or take corporate action by written consent shall, by written notice to the Secretary, request the Board of Directors to fix a record date. The Board of Directors shall promptly, but in all events within 10 days after the date on which such a request is received, adopt a resolution fixing the record date (unless a record date has previously been fixed by the Board of Directors pursuant to the first sentence of this Section 1.13(b)). If no record date has been fixed by the Board of Directors pursuant to the first sentence of this Section 1.13(b) or otherwise within 10 days of the date on which such a written request is received, the record date for determining stockholders entitled to consent to corporate action in writing without a meeting, when no prior action by the Board of Directors is required by applicable law, shall be the first date after the expiration of such 10-day time period on which a signed written consent setting forth the action taken or proposed to be taken is delivered to the corporation by delivery to its registered office in the State of Delaware, its principal place of business or an officer or agent of the corporation having custody of the book in which proceedings of meetings of stockholders are recorded. Delivery made to the corporation’s registered office shall be by hand or by certified or registered mail, return receipt requested. If no record date has been fixed by the Board of Directors and prior action by the Board of Directors is required by law, the record date for determining stockholders entitled to consent to corporate action in writing without a meeting shall be at the close of business on the day on which the Board of Directors adopts the resolution taking such prior action.

     In the event of the delivery, in the manner provided by this Section 1.13(b) and applicable law, to the corporation of a written consent or consents purporting to authorize or take corporate action and/or related revocations (such written consent or consents together with any related revocations is referred to in this section as a “Consent”), the Secretary shall provide for the safekeeping of such Consent and shall immediately appoint duly qualified and independent inspectors to: (i) conduct promptly such reasonable ministerial review as such inspectors deem necessary or appropriate for the purpose of ascertaining the sufficiency and validity of such Consent and all matters incident thereto, including whether holders of shares having the requisite voting power to authorize or take the action specified in the Consent have given consent; and (ii) deliver to the Secretary a written report regarding the foregoing. For the purpose of permitting the inspector or inspectors to perform such review, no action by written consent and without a meeting shall be effective until such inspector or inspectors have completed their review, determined that the requisite number of valid and unrevoked consents delivered to the corporation in accordance with this Section 1.13(b) and applicable law

have been obtained to authorize or take the action specified in the consents, and certified such determination for entry in the records of the corporation kept for the purpose of recording the proceedings of meetings of stockholders. If after such investigation and report the Secretary shall determine that the Consent is valid and that holders of shares having the requisite voting power to authorize or take the action specified in the Consent have given consent, that fact shall be certified on the records of the corporation kept for the purpose of recording the proceedings of meetings of stockholders, and the Consent shall be filed in such records, at which time the Consent shall become effective as stockholder action. Nothing contained in this Section 1.13(b) shall in any way be construed to suggest or imply that the Board of Directors or any stockholder shall not be entitled to contest the validity of any consent or revocation thereof, whether before or after such certification by the independent inspector or inspectors, or to take any other action (including, without limitation, the commencement, prosecution or defense of any litigation with respect thereto, and the seeking of injunctive relief in such litigation).

     (c) Following the Automatic Conversion Date, stockholders of the Corporation may not take any action by written consent in lieu of a meeting.

Unless otherwise voted by the stockholders and subject to the provisions of the Certificate of Incorporation, the whole or any part of any unissued balance of the authorized capital stock of the corporation or the whole or any part of any shares of the authorized capital stock of the corporation held in the corporation’s treasury may be issued, sold, transferred or otherwise disposed of by vote of the Board of Directors in such manner, for such lawful consideration and on such terms as the Board of Directors may determine.

      4.2 Certificates of Stock. Every holder of stock of the corporation shall be entitled to have a certificate, in such form as may be prescribed by law and by the Board of Directors, certifying the number and class of shares owned by such holder in the corporation, provided, however, that to the extent permitted by law, the Board of Directors may provide by resolution or resolutions that some or all of any or all classes or series of stock of the corporation shall be uncertificated shares. Each such certificate shall be signed by, or in the name of the corporation by, the Chairman or Vice Chairman, if any, of the Board of Directors, or the President or a Vice President, and the Treasurer or an Assistant Treasurer, or the Secretary or an Assistant Secretary of the corporation. Any or all of the signatures on the certificate may be a facsimile.

     There shall be set forth on the face or back of each certificate representing shares of such class or series of stock of the corporation a statement that the corporation will furnish without charge to each stockholder who so requests a copy of the full text of the powers, designations, preferences and relative, participating, optional or other special rights of each class of stock or series thereof and the qualifications, limitations or restrictions of such preferences and/or rights.

      4.3 Transfers. Except as otherwise established by Section 4.4 of these Bylaws or by rules and regulations adopted by the Board of Directors, and subject to applicable law, shares of stock may be transferred on the books of the corporation by the surrender to the corporation or its transfer agent of the certificate representing such shares properly endorsed or accompanied by a written assignment or power of attorney properly executed, and with such proof of authority or the authenticity of signature as the corporation or its transfer agent may reasonably require. Except as may be otherwise required by law, by the Certificate of Incorporation or by these Bylaws, the corporation shall be entitled to treat the record holder of stock as shown on its books as the owner of such stock for all purposes, including the payment of dividends and the right to vote with respect to such stock, regardless of any transfer, pledge or other disposition of such stock until the shares have been transferred on the books of the corporation in accordance with the requirements of these Bylaws.

      4.4 Lost, Stolen or Destroyed Certificates. The corporation may issue a new certificate of stock in place of any previously issued certificate alleged to have been lost, stolen or destroyed, upon such terms and conditions as the Board of Directors may prescribe, including the presentation of reasonable evidence of such loss, theft or destruction and the giving of such indemnity and posting of such bond as the Board of Directors may require for the protection of the corporation or any transfer agent or registrar.

      4.5 Record Date. The Board of Directors may fix in advance a date as a record date for the determination of the stockholders entitled to notice of or to vote at any meeting of stockholders, or entitled to receive payment of any dividend or other distribution or allotment of any rights in respect of any change, conversion or exchange of stock, or for the purpose of any other lawful action. Such record date shall not be more than 60 nor less than 10 days before the date of such meeting, nor more than 60 days prior to any other action to which such record date relates.

     If no record date is fixed, the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of business on the day before the day on which notice is given, or, if notice is waived, at the close of business on the day before the day on which the meeting is held. If no record date is fixed, the record date for determining stockholders for any other purpose shall be at the close of business on the day on which the Board of Directors adopts the resolution relating to such purpose.

     A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board of Directors may fix a new record date for the adjourned meeting.

Whenever notice is required to be given by law, by the Certificate of Incorporation or by these Bylaws, a written waiver signed by the person entitled to notice, or a waiver by electronic transmission by the person entitled to notice, whether before, at or after the time stated in such notice, shall be deemed equivalent to notice.

      5.5 Evidence of Authority. A certificate by the Secretary, or an Assistant Secretary, or a temporary Secretary, as to any action taken by the stockholders, directors, a committee or any officer or representative of the corporation shall as to all persons who rely on the certificate in good faith be conclusive evidence of such action.

     (a) The material facts as to the director’s or officer’s relationship or interest and as to the contract or transaction are disclosed or are known to the Board of Directors or the committee, and the Board or committee in good faith authorizes the contract or transaction by the affirmative votes of a majority of the disinterested directors, even though the disinterested directors be less than a quorum;

     (b) The material facts as to the director’s or officer’s relationship or interest and as to the contract or transaction are disclosed or are known to the stockholders

entitled to vote thereon, and the contract or transaction is specifically approved in good faith by the vote of the stockholders; or

     (c) The contract or transaction is fair as to the corporation as of the time it is authorized, approved or ratified, by the Board of Directors, a committee of the Board of Directors, or the stockholders.

     Common or interested directors may be counted in determining the presence of a quorum at a meeting of the Board of Directors or of a committee which authorizes the contract or transaction.

      5.8 Severability. Any determination that any provision of these Bylaws is for any reason inapplicable, illegal or ineffective shall not affect or invalidate any other provision of these Bylaws.
