(a)   To the fullest extent permitted by applicable law, as the same exists or may hereafter be amended, the Corporation shall indemnify and hold harmless each person (an “ indemnitee ”) who is or was made a party or is threatened to be made a party to or is otherwise involved in any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (a “ proceeding ”) by reason of the fact that he or she is or was a director or officer of the Corporation or, while a director or officer of the Corporation, is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust, other enterprise or nonprofit entity, including service with respect to an employee benefit plan, whether the basis of such proceeding is alleged action in an official capacity as a director, officer, employee or agent, or in any other capacity while serving as a director, officer, employee or agent, against all liability and loss suffered and expenses (including, without limitation, attorneys’ fees, judgments, fines, ERISA excise taxes and penalties and amounts paid in settlement) reasonably incurred by such indemnitee in connection with such proceeding. The Corporation shall to the fullest extent not prohibited by applicable law pay the expenses (including attorneys’ fees) incurred by an indemnitee in defending or otherwise participating in any proceeding in advance of its final disposition;  provided ,  however , that, to the extent required by applicable law, such payment of expenses in advance of the final disposition of the proceeding shall be made only upon receipt of an undertaking, by or on behalf of the indemnitee, to repay all amounts so advanced if it shall ultimately be determined that the indemnitee is not entitled to be indemnified under this  Section 8.2  or otherwise.

(c)   Any repeal or amendment of this  Section 8.2  by the stockholders of the Corporation or by changes in law, or the adoption of any other provision of this Second Amended and Restated Certificate inconsistent with this  Section 8.2 , shall, unless otherwise required by law, be prospective only (except to the extent such amendment or change in law permits the Corporation to provide broader indemnification rights on a retroactive basis than permitted prior thereto), and shall not in any way diminish or adversely affect any right or protection existing at the time of such repeal or amendment or adoption of such inconsistent provision in respect of any

proceeding (regardless of when such proceeding is first threatened, commenced or completed) arising out of, or related to, any act or omission occurring prior to such repeal or amendment or adoption of such inconsistent provision.

(d)   This Section 8.2 shall not limit the right of the Corporation, to the extent and in the manner authorized or permitted by law, to indemnify and to advance expenses to persons other than indemnitees.

(e)   In all events, the Corporation hereby agrees that (i) its obligation to an Indemnitee to provide advancement and/or indemnification to such Indemnitee is primary, (ii) any obligation of the Investor Holder (as defined below) or Sponsor Holder (as defined below) to provide advancement or indemnification hereunder or under any other indemnification agreement (whether pursuant to contract, by-laws or charter), or any obligation of an insurer of the Investor Holder or Sponsor Holder to provide insurance coverage, for the same expenses, liabilities, judgements, penalties, fines and amount paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of such expenses, liabilities, judgements, penalties, fines and amounts paid in settlement) incurred by such Indemnitee are secondary and subsequent to the foregoing obligations of the Corporation and (iii) if the Investor Holder or Sponsor Holder pays or causes to be paid, for any reason, any amounts otherwise indemnifiable, hereunder or under any other indemnification agreement (whether pursuant to contract, by-laws or charter) with such Indemnitee, then (x) the Investor Holder or Sponsor Holder (as the case may be), shall be fully subrogated to all rights of such Indemnitee with respect to such payment and (y) the Corporation shall fully indemnify, reimburse and hold harmless the Investor Holder or Sponsor Holder (as the case may be), for all such payments actually made by the Investor Holder or Sponsor Holder (as the case may be).

Section 2.3. Notices. Notice of each stockholders meeting stating the place, if any, date, and time of the meeting, and the means of remote communication, if any, by which stockholders and proxy holders may be deemed to be present in person and vote at such meeting, shall be given in the manner permitted by Section 9.3 to each stockholder entitled to vote thereat by the Corporation not less than 10 nor more than 60 days before the date of the meeting. If said notice is for a stockholders meeting other than an annual meeting, it shall in addition state the purpose or purposes for which the meeting is called, and the business transacted at such meeting shall be limited to the matters so stated in the Corporation’s notice of meeting (or any supplement thereto). Any meeting of stockholders as to which notice has been given may be postponed, and any special meeting of stockholders as to which notice has been given may be cancelled, by the Board upon public announcement (as defined in Section 2.7(c)) given before the date previously scheduled for such meeting.

Section 2.4. Quorum . Except as otherwise provided by applicable law, the Corporation’s Certificate of Incorporation, as the same may be amended or restated from time to time (the “ Certificate of Incorporation ”) or these By Laws, the presence, in person or by proxy, at a stockholders meeting of the holders of shares of outstanding capital stock of the Corporation representing a majority of the voting power of all outstanding shares of capital stock of the Corporation entitled to vote at such meeting shall constitute a quorum for the transaction of business at such meeting, except that when specified business is to be voted on by a class or series of stock voting as a class, the holders of shares representing a majority of the voting power of the outstanding shares of such class or series shall constitute a quorum of such class or series for the transaction of such business. If a quorum shall not be present or represented by proxy at any meeting of the stockholders of the Corporation, the chairman of the meeting may adjourn the meeting from time to time in the manner provided in Section 2.6 until a quorum shall attend. The stockholders present at a duly convened meeting may continue to transact business until adjournment, notwithstanding the withdrawal of enough stockholders to leave less than a quorum. Shares of its own stock belonging to the Corporation or to another corporation, if a majority of the voting power of the shares entitled to vote in the election of directors of such other corporation is held, directly or indirectly, by the Corporation, shall neither be entitled to vote nor be counted for quorum purposes; provided, however, that the foregoing shall not limit the right of the Corporation or any such other corporation to vote shares held by it in a fiduciary capacity.

Section 2.5. Voting of Shares .

(a)    Voting Lists . The Secretary shall prepare, or shall cause the officer or agent who has charge of the stock ledger of the Corporation to prepare, at least 10 days before every meeting of stockholders, a complete list of the stockholders of record entitled to vote at such meeting and showing the address and the number of shares registered in the name of each stockholder. Nothing contained in this Section 2.5(a)  shall require the Corporation to include electronic mail addresses or other electronic contact information on such list. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, during ordinary business hours for a period of at least 10 days prior to the meeting: (i) on a reasonably accessible electronic network, provided that the information required to gain access to such list is provided with the notice of the meeting, or (ii) during ordinary business hours, at the principal place of business of the Corporation. In the event that the Corporation determines to make the list available on an electronic network, the Corporation may take reasonable steps to ensure that such information is available only to stockholders of the Corporation. If the meeting is to be held at a place, then the list shall be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any stockholder who is present. If a meeting of stockholders is to be held solely by means of remote communication as permitted by Section 9.5(a) , the list shall be open to the examination of any stockholder during the whole time of the meeting on a reasonably accessible electronic network, and the information required to access such list shall be provided with the notice of meeting. The stock ledger shall be the only evidence as to who are the stockholders entitled to examine the list required by this Section 2.5(a)  or to vote in person or by proxy at any meeting of stockholders.

(b)     Manner of Voting . At any stockholders meeting, every stockholder entitled to vote may vote in person or by proxy. If authorized by the Board, the voting by stockholders or proxy holders at any meeting conducted by remote communication may be effected by a ballot submitted by electronic transmission (as defined in Section 9.3 ), provided that any such electronic transmission must either set forth or be submitted with information from which the Corporation can determine that the electronic transmission was authorized by the stockholder or proxy holder. The Board, in its discretion, or the chairman of the meeting of stockholders, in such person’s discretion, may require that any votes cast at such meeting shall be cast by written ballot.

(c)     Proxies . Each stockholder entitled to vote at a meeting of stockholders or to express consent or dissent to corporate action in writing without a meeting may authorize another person or persons to act for such stockholder by proxy, but no such proxy shall be voted or acted upon after three years from its date, unless the proxy provides for a longer period. Proxies need not be filed with the Secretary of the Corporation until the meeting is called to order, but shall be filed with the Secretary before being voted. Without limiting the manner in which a stockholder may authorize another person or persons to act for such stockholder as proxy, either of the following shall constitute a valid means by which a stockholder may grant such authority.

(i)       A stockholder may execute a writing authorizing another person or persons to act for such stockholder as proxy. Execution may be accomplished by the stockholder or such stockholder’s

authorized officer, director, employee or agent signing such writing or causing such person’s signature to be affixed to such writing by any reasonable means, including, but not limited to, by facsimile signature.

(ii)         A stockholder may authorize another person or persons to act for such stockholder as proxy by transmitting or authorizing the transmission of an electronic transmission to the person who will be the holder of the proxy or to a proxy solicitation firm, proxy support service organization or like agent duly authorized by the person who will be the holder of the proxy to receive such transmission, provided that any such electronic transmission must either set forth or be submitted with information from which it can be determined that the electronic transmission was authorized by the stockholder. Any copy, facsimile telecommunication or other reliable reproduction of the writing or transmission authorizing another person or persons to act as proxy for a stockholder may be substituted or used in lieu of the original writing or transmission for any and all purposes for which the original writing or transmission could be used; provided that such copy, facsimile telecommunication or other reproduction shall be a complete reproduction of the entire original writing or transmission.

(d)     Required Vote . Subject to the rights of the holders of one or more series of preferred stock of the Corporation (“ Preferred Stock ”), voting separately by class or series, to elect directors pursuant to the terms of one or more series of Preferred Stock, the election of directors shall be determined by a plurality of the votes cast by the stockholders present in person or represented by proxy at the meeting and entitled to vote thereon. All other matters shall be determined by the vote of a majority of the votes cast by the stockholders present in person or represented by proxy at the meeting and entitled to vote thereon, unless the matter is one upon which, by applicable law, the Certificate of Incorporation, these By Laws or applicable stock exchange rules, a different vote is required, in which case such provision shall govern and control the decision of such matter.

(e)     Inspectors of Election . The Board may, and shall if required by law, in advance of any meeting of stockholders, appoint one or more persons as inspectors of election, who may be employees of the Corporation or otherwise serve the Corporation in other capacities, to act at such meeting of stockholders or any adjournment thereof and to make a written report thereof. The Board may appoint one or more persons as alternate inspectors to replace any inspector who fails to act. If no inspectors of election or alternates are appointed by the Board, the chairman of the meeting shall appoint one or more inspectors to act at the meeting. Each inspector, before discharging his or her duties, shall take and sign an oath faithfully to execute the duties of inspector with strict impartiality and according to the best of his or her ability. The inspectors shall ascertain and report the number of outstanding shares and the voting power of each; determine the number of shares present in person or represented by proxy at the meeting and the validity of proxies and ballots; count all votes and ballots and report the results; determine and retain for a reasonable period a record of the disposition of any challenges made to any determination by the inspectors; and certify their determination of the number of shares represented at the meeting and their count of all votes and ballots. No person who is a candidate for an office at an election may serve as an inspector at such election. Each report of an inspector shall be in writing and signed by the inspector or by a majority of them if there is more than one inspector acting at such meeting. If there is more than one inspector, the report of a majority shall be the report of the inspectors.

Section 2.6. Adjournments . Any meeting of stockholders, annual or special, may be adjourned by the chairman of the meeting, from time to time, whether or not there is a quorum, to reconvene at the same or some other place. Notice need not be given of any such adjourned meeting if the date, time, and place, if any, thereof, and the means of remote communication, if any, by which stockholders and proxy holders may be deemed to be present in person and vote at such adjourned meeting are announced at the meeting at which the adjournment is taken. At the adjourned meeting the stockholders, or the holders of any class or series of stock entitled to vote separately as a class, as the case may be, may transact any business that might have been transacted at the original meeting. If the adjournment is for more than 30 days, or if after the adjournment a new record date is fixed for the adjourned meeting, notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting.

Section 7.5. Lost, Destroyed or Wrongfully Taken Certificates .

(a)       If an owner of a certificate representing shares claims that such certificate has been lost, destroyed or wrongfully taken, the Corporation shall issue a new certificate representing such shares or such shares in uncertificated form if the owner: (i) requests such a new certificate before the Corporation has notice that the certificate representing such shares has been acquired by a protected purchaser; (ii) if requested by the Corporation, delivers to the Corporation a bond sufficient to indemnify the Corporation against any claim that may be made against the Corporation on account of the alleged loss, wrongful taking or destruction of such certificate or the issuance of such new certificate or uncertificated shares; and (iii) satisfies other reasonable requirements imposed by the Corporation.

(b)     If a certificate representing shares has been lost, apparently destroyed or wrongfully taken, and the owner fails to notify the Corporation of that fact within a reasonable time after the owner has notice of such loss, apparent destruction or wrongful taking and the Corporation registers a transfer of such shares before receiving notification, the owner shall be precluded from asserting against the Corporation any claim for registering such transfer or a claim to a new certificate representing such shares or such shares in uncertificated form.

(ii)(A) with respect to certificated shares, the endorsement is made by the person specified by the certificate as entitled to such shares; (B) with respect to uncertificated shares, an instruction is made by the registered owner of such uncertificated shares; or (C) with respect to certificated shares or uncertificated shares, the endorsement or instruction is made by any other appropriate person or by an agent who has actual authority to act on behalf of the appropriate person;

(iii)            the Corporation has received a guarantee of signature of the person signing such endorsement or instruction or such other reasonable assurance that the endorsement or instruction is genuine and authorized as the Corporation may request;

(v)      such other conditions for such transfer as shall be provided for under applicable law have been satisfied.

(b)      Whenever any transfer of shares shall be made for collateral security and not absolutely, the Corporation shall so record such fact in the entry of transfer if, when the certificate for such shares is presented to the Corporation for transfer or, if such shares are uncertificated, when the instruction for registration of transfer thereof is presented to the Corporation, both the transferor and transferee request the Corporation to do so.

Section 7.7. Registered Stockholders . Before due presentment for registration of transfer of a certificate representing shares of the Corporation or of an instruction requesting registration of transfer of

uncertificated shares, the Corporation may treat the registered owner as the person exclusively entitled to inspect for any proper purpose the stock ledger and the other books and records of the Corporation, vote such shares, receive dividends or notifications with respect to such shares and otherwise exercise all the rights and powers of the owner of such shares, except that a person who is the beneficial owner of such shares (if held in a voting trust or by a nominee on behalf of such person) may, upon providing documentary evidence of beneficial ownership of such shares and satisfying such other conditions as are provided under applicable law, may also so inspect the books and records of the Corporation.

Section 7.8. Effect of the Corporation’s Restriction on Transfer .

(a)    A written restriction on the transfer or registration of transfer of shares of the Corporation or on the amount of shares of the Corporation that may be owned by any person or group of persons, if permitted by the DGCL and noted conspicuously on the certificate representing such shares or, in the case of uncertificated shares, contained in a notice, offering circular or prospectus sent by the Corporation to the registered owner of such shares within a reasonable time prior to or after the issuance or transfer of such shares, may be enforced against the holder of such shares or any successor or transferee of the holder including an executor, administrator, trustee, guardian or other fiduciary entrusted with like responsibility for the person or estate of the holder.

(b)       A restriction imposed by the Corporation on the transfer or the registration of shares of the Corporation or on the amount of shares of the Corporation that may be owned by any person or group of persons, even if otherwise lawful, is ineffective against a person without actual knowledge of such restriction unless: (i) the shares are certificated and such restriction is noted conspicuously on the certificate; or (ii) the shares are uncertificated and such restriction was contained in a notice, offering circular or prospectus sent by the Corporation to the registered owner of such shares prior to or within a reasonable time after the issuance or transfer of such shares.

Section 7.9. Regulations . The Board shall have power and authority to make such additional rules and regulations, subject to any applicable requirement of law, as the Board may deem necessary and appropriate with respect to the issue, transfer or registration of transfer of shares of stock or certificates representing shares.

ARTICLE VIII

INDEMNIFICATION

Section 8.1. Right to Indemnification . To the fullest extent permitted by applicable law, as the same exists or may hereafter be amended, the Corporation shall indemnify and hold harmless each person (hereinafter an “ Indemnitee ”)who was or is made a party or is threatened to be made a party to or is otherwise involved in any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (hereinafter a “ proceeding ”), by reason of the fact that he or she is or was a director or officer of the Corporation or, while a director or officer of the Corporation, is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust, other enterprise or nonprofit entity, including service with respect to an employee benefit plan, whether the basis of such proceeding is alleged action in an official capacity as a director, officer, employee or agent, or in any other capacity while serving as a director, officer, employee or agent, against all liability and loss suffered and expenses (including, without limitation, attorneys’ fees, judgments, fines, ERISA excise taxes and penalties and amounts paid in settlement) reasonably incurred by such Indemnitee in connection with such proceeding; provided, however, that, except as provided in Section 8.3 with respect to proceedings to enforce rights to indemnification, the Corporation shall indemnify an Indemnitee in connection with a proceeding (or part thereof) initiated by such Indemnitee only if such proceeding (or part thereof) was authorized by the Board.

Section 8.2. Right to Advancement of Expenses . In addition to the right to indemnification conferred in Section 8.1 , an Indemnitee shall also have the right to be paid by the Corporation to the fullest extent not prohibited by applicable law the expenses (including, without limitation, attorneys’ fees) incurred in defending or otherwise participating in any such proceeding in advance of its final disposition (hereinafter an “ advancement of expenses ”); provided, however, that, if the Delaware General Corporation Law (“ DGCL ”) requires, an advancement of expenses incurred by an Indemnitee in his or

her capacity as a director or officer of the Corporation (and not in any other capacity in which service was or is rendered by such Indemnitee, including, without limitation, service to an employee benefit plan) shall be made only upon the Corporation’s receipt of an undertaking (hereinafter an “ undertaking ”), by or on behalf of such Indemnitee, to repay all amounts so advanced if it shall ultimately be determined that such Indemnitee is not entitled to be indemnified under this Article VIII or otherwise.

Section 8.3. Right of Indemnitee to Bring Suit . If a claim under Section 8.1 or Section 8.2 is not paid in full by the Corporation within 60 days after a written claim therefor has been received by the Corporation, except in the case of a claim for an advancement of expenses, in which case the applicable period shall be 20 days, the Indemnitee may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim. If successful in whole or in part in any such suit, or in a suit brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the Indemnitee shall also be entitled to be paid the expense of prosecuting or defending such suit. In (a) any suit brought by the Indemnitee to enforce a right to indemnification hereunder (but not in a suit brought by an Indemnitee to enforce a right to an advancement of expenses) it shall be a defense that, and (b) in any suit brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the Corporation shall be entitled to recover such expenses upon a final judicial decision from which there is no further right to appeal (hereinafter a “ final adjudication ”) that, the Indemnitee has not met any applicable standard for indemnification set forth in the DGCL. Neither the failure of the Corporation (including its directors who are not parties to such action, a committee of such directors, independent legal counsel, or its stockholders) to have made a determination prior to the commencement of such suit that indemnification of the Indemnitee is proper in the circumstances because the Indemnitee has met the applicable standard of conduct set forth in the DGCL, nor an actual determination by the Corporation (including a determination by its directors who are not parties to such action, a committee of such directors, independent legal counsel, or its stockholders) that the Indemnitee has not met such applicable standard of conduct, shall create a presumption that the Indemnitee has not met the applicable standard of conduct or, in the case of such a suit brought by the Indemnitee, shall be a defense to such suit. In any suit brought by the Indemnitee to enforce a right to indemnification or to an advancement of expenses hereunder, or by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the burden of proving that the Indemnitee is not entitled to be indemnified, or to such advancement of expenses, under this Article VIII or otherwise shall be on the Corporation.

Section 8.4. Non-Exclusivity of Rights . The rights provided to any Indemnitee pursuant to this Article VIII shall not be exclusive of any other right, which such Indemnitee may have or hereafter acquire under applicable law, the Certificate of Incorporation, these By Laws, an agreement, a vote of stockholders or disinterested directors, or otherwise.

Section 8.5. Insurance . The Corporation may maintain insurance, at its expense, to protect itself and/or any director, officer, employee or agent of the Corporation or another corporation, partnership, joint venture, trust or other enterprise against any expense, liability or loss, whether or not the Corporation would have the power to indemnify such person against such expense, liability or loss under the DGCL.

Section 8.6. Indemnitor of First Resort. In all events, the Corporation hereby agrees that (i) its obligation to an Indemnitee to provide advancement and/or indemnification to such Indemnitee is primary, (ii) any obligation of the Investor Holder (as defined in the Certificate of Incorporation) or Sponsor Holder (as defined in the Certificate of Corporation) to provide advancement or indemnification hereunder or under any other indemnification agreement (whether pursuant to contract, by-laws or charter), or any obligation of an insurer of the Investor Holder (as defined in the Certificate of Corporation) or Sponsor Holder (as defined in the Certificate of Corporation) to provide insurance coverage, for the same expenses, liabilities, judgements, penalties, fines and amount paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of such expenses, liabilities, judgements, penalties, fines and amounts paid in settlement) incurred by such Indemnitee are secondary and subsequent to the foregoing obligations of the Corporation and (iii) if the Investor Holder (as defined in the Certificate of Corporation) or Sponsor Holder (as defined in the Certificate of Corporation) pays or causes to be paid, for any reason, any amounts otherwise indemnifiable, hereunder or under any other indemnification agreement (whether pursuant to contract, by-laws or charter) with such Indemnitee, then (x) the Investor Holder (as defined in the Certificate of Corporation) or Sponsor Holder (as defined in the Certificate of Corporation) (as the case may be), shall be fully subrogated to all rights of such Indemnitee with respect to such payment and (y) the Corporation

shall fully indemnify, reimburse and hold harmless the Investor Holder (as defined in the Certificate of Corporation) or Sponsor Holder (as defined in the Certificate of Corporation) (as the case may be), for all such payments actually made by the Investor Holder (as defined in the Certificate of Corporation) or Sponsor Holder (as defined in the Certificate of Corporation) (as the case may be).

Section 8.7. Indemnification of Other Persons . This Article VIII shall not limit the right of the Corporation to the extent and in the manner authorized or permitted by law to indemnify and to advance expenses to persons other than Indemnitees. Without limiting the foregoing, the Corporation may, to the extent authorized from time to time by the Board, grant rights to indemnification and to the advancement of expenses to any employee or agent of the Corporation and to any other person who is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to an employee benefit plan, to the fullest extent of the provisions of this Article VIII with respect to the indemnification and advancement of expenses of Indemnitees under this Article VIII .

Section 8.8. Amendments . Any repeal or amendment of this Article VIII by the Board or the stockholders of the Corporation or by changes in applicable law, or the adoption of any other provision of these By Laws inconsistent with this Article VIII , will, to the extent permitted by applicable law, be prospective only (except to the extent such amendment or change in applicable law permits the Corporation to provide broader indemnification rights to Indemnitees on a retroactive basis than permitted prior thereto), and will not in any way diminish or adversely affect any right or protection existing hereunder in respect of any act or omission occurring prior to such repeal or amendment or adoption of such inconsistent provision; provided however, that amendments or repeals of this Article VIII shall require the affirmative vote of the stockholders holding at least 66.7% of the voting power of all outstanding shares of capital stock of the Corporation.

Section 8.9. Certain Definitions . For purposes of this Article VIII , (a) references to “other enterprise” shall include any employee benefit plan; (b) references to “fines” shall include any excise taxes assessed on a person with respect to an employee benefit plan; (c) references to “serving at the request of the Corporation” shall include any service that imposes duties on, or involves services by, a person with respect to any employee benefit plan, its participants, or beneficiaries; and (d) a person who acted in good faith and in a manner such person reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner “not opposed to the best interest of the Corporation” for purposes of Section 145 of the DGCL.

Section 8.10. Contract Rights . The rights provided to Indemnitees pursuant to this Article VIII shall be contract rights and such rights shall continue as to an Indemnitee who has ceased to be a director, officer, agent or employee and shall inure to the benefit of the Indemnitee’s heirs, executors and administrators.

Section 8.11. Severability . If any provision or provisions of this Article VIII shall be held to be invalid, illegal or unenforceable for any reason whatsoever: (a) the validity, legality and enforceability of the remaining provisions of this Article VIII shall not in any way be affected or impaired thereby; and (b) to the fullest extent possible, the provisions of this Article VIII (including, without limitation, each such portion of this Article VIII containing any such provision held to be invalid, illegal or unenforceable) shall be construed so as to give effect to the intent manifested by the provision held invalid, illegal or unenforceable.

ARTICLE IX

(a)     In order that the Corporation may determine the stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, the Board may fix a record date, which shall not precede the date upon which the resolution fixing the record date is adopted by the Board, and which record date shall not be more than 60 nor less than 10 days before the date of such meeting. If no record date is fixed by the Board, 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 business day next preceding the day on which notice is given, or, if notice is waived, at the close of business on the business day next preceding the day on which the meeting is held. 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 may fix a new record date for the adjourned meeting.

(b)     In order that the Corporation may determine the stockholders entitled to receive payment of any dividend or other distribution or allotment of any rights or the stockholders entitled to exercise any rights in respect of any change, conversion or exchange of stock, or for the purpose of any other lawful action, the Board may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted, and which record date shall be not more than 60 days prior to such action. If no record date is fixed, the record date for determining stockholders for any such purpose shall be at the close of business on the day on which the Board adopts the resolution relating thereto.

Section 9.3. Means of Giving Notice .

(a)    Notice to Directors .

(b)     Notice to Stockholders . Whenever under applicable law, the Certificate of Incorporation or these By Laws notice is required to be given to any stockholder, such notice may be given (i) in writing and sent either by hand delivery, through the United States mail, or by a nationally recognized overnight delivery service for next day delivery, or (ii) by means of a form of electronic transmission consented to by the stockholder, to the extent permitted by, and subject to the conditions set forth in Section 232 of the DGCL. A notice to a stockholder shall be deemed given as follows: (i) if given by hand delivery, when actually received by the stockholder, (ii) if sent through the United States mail, when deposited in the United States mail, with postage and fees thereon prepaid, addressed to the stockholder at the stockholder’s address appearing on the stock ledger of the Corporation, (iii) if sent for next day delivery by a nationally recognized overnight delivery service, when deposited with such service, with fees thereon prepaid, addressed to the stockholder at the stockholder’s address appearing on the stock ledger of the Corporation, and (iv) if given by a form of electronic transmission consented to by the stockholder to whom the notice is given and otherwise meeting the requirements set forth above, (A) if by facsimile transmission, when directed to a number at which the stockholder has consented to receive notice, (B) if by electronic mail, when directed to an electronic mail address at which the stockholder has consented to receive notice, (C) if by a posting on an electronic network together with separate notice to the stockholder of such specified posting, upon the later of (1) such posting and (2) the giving of such separate notice, and (D) if by any other form of electronic transmission, when directed to the stockholder. A stockholder may revoke such stockholder’s consent to receiving notice by means of electronic communication by giving written notice of such revocation to the Corporation. Any such consent shall be

deemed revoked if (1) the Corporation is unable to deliver by electronic transmission two consecutive notices given by the Corporation in accordance with such consent and (2) such inability becomes known to the Secretary or an Assistant Secretary or to the Corporation’s transfer agent, or other person responsible for the giving of notice; provided, however, the inadvertent failure to treat such inability as a revocation shall not invalidate any meeting or other action.

(c)     Electronic Transmission . “ Electronic transmission ” means any form of communication, not directly involving the physical transmission of paper, that creates a record that may be retained, retrieved and reviewed by a recipient thereof, and that may be directly reproduced in paper form by such a recipient through an automated process, including but not limited to transmission by telex, facsimile telecommunication, electronic mail, telegram and cablegram.

Any stockholder who fails to object in writing to the Corporation within 60 days of having been given written notice by the Corporation of its intention to send such a single written notice shall be deemed to have consented to receiving such single written notice.

(e)     Exceptions to Notice Requirements .

(ii)  Each holder of Series A Preferred Stock hereby irrevocably delegates all power and authority to the Stockholders’ Representative to exercise, on behalf of such holder of Series A Preferred Stock, any and all rights of such holder in respect of such Series A Preferred Stock pursuant to  Section 4(d) , this  Section 6  and  Section 8 , including the granting of any waivers or the exercise of any consent, approval or voting rights or powers on behalf of such holder.

(iii)  The Stockholders’ Representative shall not, in the absence of bad faith, willful misconduct or gross negligence, have any liability to the holders of Series A Preferred Stock whatsoever with respect to its actions, decisions and determinations, and shall be entitled to assume that all actions, decisions and determinations are fully authorized by each and every one of the holders of Series A Preferred Stock. The Corporation hereby agrees that the Stockholders’ Representative shall not, in its capacity as such, have any liability to the Corporation or any of its Affiliates whatsoever with respect to its actions, decisions or determinations.

(c)     Consent Rights.     Notwithstanding the foregoing, until the Dividend Cessation Date of all Series A Preferred Stock, the Corporation shall not, and shall cause its Subsidiaries not to, directly or indirectly (whether by merger, consolidation, amendment of this Certificate of Designations or otherwise), without the prior written approval of the Stockholders’ Representative:

(i)  create, or authorize the creation of, or issue or obligate itself to issue any shares of, (A) Senior Stock, (B) Parity Stock (including any Series A Preferred Stock, other than the Series A Preferred Stock issued pursuant to the Merger Agreement), (C) any Capital Stock that votes as a single class with the Series A Preferred Stock on any of the matters which require the consent of the holders of a majority of the Series A Preferred Stock pursuant to this  Section 6 , or (D) any Capital Stock of a Subsidiary of the Corporation, other than a wholly owned Subsidiary of the Corporation;  provided ,  that , this clause (D) shall not apply to Capital Stock of a Subsidiary of the Corporation issued as consideration for a bona-fide acquisition by the Corporation or any of its Subsidiaries approved by the Board and the primary purpose of which is not to obtain financing;

(ii)  reclassify, alter or amend any Capital Stock of the Corporation or its Subsidiaries if such reclassification, alteration or amendment would render such other Capital Stock senior to or pari passu with the Series A Preferred Stock in respect of the distribution of assets on the liquidation, dissolution or winding up of the Corporation or the payment of dividends;

(iii)  enter into any agreement with respect to, or consummate, any merger, consolidation or similar transaction with any other Person pursuant to which the Corporation or such Subsidiary would not be the surviving entity in such transaction, if as a result of such transaction, any capital stock or equity or equity-linked securities of such Person would rank senior to or pari passu with the Series A Preferred Stock as to the payment of dividends or in the distribution of assets in the event of any voluntary or involuntary liquidation, dissolution or winding up of the surviving entity or such Subsidiary;

(iv)  assume, incur or guarantee, or authorize the creation, assumption, incurrence or guarantee of, any indebtedness for borrowed money (specifically excluding letters of credit, performance or payment bonds, and capitalized lease obligations) if, after taking into account such assumption, incurrence or guarantee of such indebtedness for borrowed money, the aggregate outstanding amount of such indebtedness for borrowed money of the Company and its Subsidiaries would exceed $5,000,000 on a consolidated basis, other than (x) any indebtedness for borrowed money under the credit facility being executed and delivered in connection with the closing of the Merger Agreement (the “ Existing Facility ”), or (y) any refinancing thereof in a principal amount not to exceed the available amount under the Existing Facility;

(v)  authorize or consummate any Change of Control or Liquidation Event unless on or prior to the consummation of such Change of Control or Liquidation Event, all shares of Series A Preferred Stock will be redeemed, paid or purchased in full at the Redemption Price; or

(vi)  alter, amend, supplement, restate, waive or otherwise modify any provision of this Certificate of Designations or any other governing document of the Corporation (including any other Certificate of Designations) in a manner that would reasonably be expected to be materially adverse to the rights or obligations of the holders of the Series A Preferred Stock.

Section 7.     Redemption Rights .

(a)     Redemption Events .

(i)  The Corporation may, at any time and from time to time, redeem all or any portion of the shares of Series A Preferred Stock then outstanding;  provided , that any such redemption shall be on a  pro rata  basis among the holders of Series A Preferred Stock in accordance with the number of shares of Series A Preferred Stock then held by such holders.

(ii)  Concurrently with and as a condition to the consummation of a Change of Control, the Corporation shall repurchase all Series A Preferred Stock then outstanding.

(iii)  In the event of a Qualifying Equity Sale, the Corporation shall, as promptly as practicable (but in any event within three (3) Business Days of the consummation of such Qualifying Equity Sale), use all of the Net Cash Proceeds from such Qualifying Equity Sale to redeem the maximum number of shares of Series A Preferred Stock that are redeemable from such Net Cash Proceeds from such Qualifying Equity Sale at the Redemption Price (as defined below) per share; provided that any such redemption shall be on a  pro rata  basis among the holders of Series A Preferred Stock in accordance with the number of shares of Series A Preferred Stock then held by such holders.

(iv)  In the event of a Significant Disposition, the Corporation shall, as promptly as practicable (but in any event within three (3) Business Days of the consummation of such Significant Disposition), use all of the Net Cash Proceeds from such Significant Disposition to redeem the maximum number of shares of Series A Preferred Stock that are redeemable from such Net Cash Proceeds from such Significant Disposition at the Redemption Price per share; provided that (x) any such redemption shall be on a  pro rata basis among the holders of Series A Preferred Stock in accordance with the number of shares of Series A Preferred Stock then held by such holders and (y) if any portion of the consideration from such Significant Disposition is not in the form of cash consideration, then for purposes of this clause (iv) any such non-cash consideration shall be included in the calculation of Net Cash Proceeds as and when converted to cash.

(b)     Redemption Price.     In connection with any redemption, the Corporation shall pay a price per share of Series A Preferred Stock equal to the Stated Value thereof plus all accrued and unpaid dividends thereon calculated through the day prior to such redemption (the “ Redemption Price ”). There shall be no premium or penalty payable in connection with any redemption. To the fullest extent permitted by law, if the Corporation pays or makes available in accordance with  Section 7(f)  to the holder of a share of Series A Preferred Stock the Redemption Price in respect of such share of Series A Preferred Stock when and as required, such share of Series A Preferred Stock shall be cancelled notwithstanding failure of the holder thereof to return the certificate representing such share; provided that such cancellation shall not impair the right of the holder of such share to subsequently receive the amount that has been made available.

(c)     Notice of Redemption.     Except as otherwise provided herein, the Corporation shall provide written notice (a “ Redemption Notice ”) to the Stockholders’ Representative and each record holder of Series A Preferred Stock of any redemption not more than 60 nor less than 10 days prior to the date on which such redemption is to be made. Such notice shall set forth in reasonable detail the date on which such redemption is to be made (the “ Redemption Date ”) and a calculation specifying the amount owed to such holder by the Corporation in respect of each share of Series A Preferred Stock held by such holder as of the Redemption Date. To the extent that any redemption is being made in connection with the occurrence of one or more events, the Corporation may make the redemption contingent upon consummation of such event.

(d)     Redemptions of Less than All Shares.     If the Corporation is redeeming less than all of the shares of Series A Preferred Stock then outstanding, the Corporation shall redeem such number of shares of Series A Preferred Stock and each class or series of Parity Stock required to be redeemed, if any, such that the amount payable to each holder of Series A Preferred Stock and Parity Stock in respect of such shares of Series A Preferred Stock and/or Parity Stock, as the case may be, upon a Liquidation Event immediately after consummation of such redemption (and after giving effect to any conversion in connection with such

8

redemption) bears, as nearly as practicable, the same proportion to the total amount payable to holders of Series A Preferred Stock and Parity Stock upon a Liquidation Event in respect of such shares immediately prior to consummation of such redemption (and after giving effect to any conversion in connection with such redemption). In the event that, for any holder of Series A Preferred Stock, fewer than the total number of shares of Series A Preferred Stock represented by any certificate are redeemed, a new certificate representing the number of unredeemed shares of Series A Preferred Stock shall be issued to the holder thereof without cost to such holder within five Business Days after surrender of the certificate representing the redeemed shares of Series A Preferred Stock.

(e)     Other Redemptions or Acquisitions.     The Series A Preferred Stock shall have no maturity date or scheduled redemption date. Nothing herein shall be deemed to limit the right of the Corporation to purchase such Series A Preferred Stock from time to time.

(f)     Effectiveness of Redemption.     If a Redemption Notice has been duly given and if, on or before the Redemption Date specified in the Redemption Notice, all funds necessary for the redemption have been set aside by the Corporation, separate and apart from its other assets, in trust or escrow for the pro rata benefit of the holders of shares of Series A Preferred Stock called for redemption, so as to be and continue to be available therefor (subject to applicable escheat laws), or deposited by the Corporation with a bank or trust company in trust or escrow for the pro rata benefit of the holders of the shares of Series A Preferred Stock called for redemption, then, notwithstanding that any certificate for any share so called for redemption has not been surrendered for cancellation, on and after the Redemption Date, all shares of Series A Preferred Stock so called for redemption shall be cancelled and shall cease to be outstanding, all dividends with respect to such shares shall cease to accrue on such Redemption Date, and all rights with respect to such shares shall forthwith on such Redemption Date cease and terminate without further liability to, or obligation of, the Corporation, except only the right of the holders thereof to receive the Redemption Price without interest.

Section 8.     Conversion .

(a)     Upon Election by Holders.     Any holder of Series A Preferred Stock may elect, by written notice to the Corporation (x) at any time and from time to time on or after the third anniversary of the Closing Date or (y) at any time and from time to time on or after the occurrence of a Non-Payment Event or Default Event until such Non-Payment Event or Default Event is cured by the Corporation, to cause the Corporation to convert, without the payment of additional consideration by such holder, all or any portion of the issued and outstanding shares of Series A Preferred Stock held by such holder, as specified by such holder in such notice, into a number of shares of Common Stock determined in accordance with  Section 8(b)  on the terms described below. Notwithstanding any other provision hereof, if a conversion of Series A Preferred Stock pursuant to this  Section 8(a)  is to be made in connection with a transaction involving the Corporation, the conversion of any shares of Series A Preferred Stock may, at the election of the holder thereof, be conditioned upon the consummation of such transaction, in which case such conversion shall not be deemed to be effective until such transaction has been consummated. A holder of Series A Preferred Stock must do each of the following in order to convert shares of Series A Preferred Stock: (i) complete the conversion notice provided by the Conversion Agent, and deliver an executed copy of such notice to the Conversion Agent; (ii) deliver a certificate or certificates representing the shares of Series A Preferred Stock to be converted to the Conversion Agent, or, if such certificates have been lost, mutilated or destroyed, an affidavit of loss; (iii) if reasonably required by the Conversion Agent, furnish appropriate endorsements and transfer documents; and (iv) if required, pay any stock transfer, documentary, stamp or similar taxes. The date on which a holder of Series A Preferred Stock complies with the procedures in this  Section 8(a)  with regard to the conversion of shares of Series A Preferred Stock is referred to as the “Conversion Date” applicable to such shares. The Conversion Agent shall, on behalf of the holder of such Series A Preferred Stock, convert the Series A Preferred Stock into shares of Common Stock, in accordance with the terms of the notice delivered by such holder described above and this Certificate of Designations. On the Conversion Date, the shares of Series A Preferred Stock so converted will be canceled and will cease to be issued and outstanding (and all rights of the holder of such Series A Preferred Stock (in its capacity as such and only with respect to the shares of Series A Preferred Stock so converted) shall terminate without further liability to, or obligation of, the Corporation effective as of the

9

Conversion Date) and the Common Stock issued upon such conversion in respect thereof shall be issued and outstanding (and no holder of shares of Series A Preferred Stock to be converted shall have any rights prior to the Conversion Date in respect of such Common Stock issued upon conversion). Upon the conversion of Series A Preferred Stock in connection with the occurrence of a Non-Payment Event, the holders of such Series A Preferred Stock shall have no other remedies available for such Non-Payment Event and the Corporation shall have no further liability for, or obligation to, the holders of such Series A Preferred Stock in respect of such Non-Payment Event.

(b)     Effect of Conversion.     Subject to compliance by a holder of Series A Preferred Stock with the requirements of  Section 8(a) , the Corporation shall issue to such holder a number of shares of Common Stock determined by dividing (i) the Stated Value plus accrued and unpaid dividends as of the Conversion Date for the share(s) of Series A Preferred Stock to be converted by (ii) the VWAP per share of Common Stock for the 30 consecutive Trading Days ending on the Trading Day immediately prior to the Conversion Date;  provided ,  however , that if a Non-Payment Event or Default Event has occurred and has not been cured by the Corporation as of the Conversion Date, the Corporation shall issue to such holder a number of shares of Common Stock determined by dividing (1) the Stated Value plus accrued and unpaid dividends as of the Conversion Date for the share(s) of Series A Preferred Stock to be converted by (2) the product of (x) 90% multiplied by (y) the VWAP per share of Common Stock for the 30 consecutive Trading Days ending on the Trading Day immediately prior to the Conversion Date.

(c)     Obligations of Corporation on Conversion.     As promptly as practicable (but in any event within three (3) Business Days) after a conversion has been effected, the Corporation shall, or shall cause the Conversion Agent to, mail to the converting holder:

(i)  a certificate or certificates representing the number of shares of Common Stock issuable by reason of such conversion in such name or names and such denomination or denominations as the converting holder has specified or, upon the request of the converting holder, evidence of the issuance of such shares in book-entry form; and

(ii)  a certificate representing any shares of Series A Preferred Stock which were represented by the certificate or certificates delivered to the Corporation in connection with such conversion but which were not converted.

(d)     Reservation of Common Stock.     The Corporation shall at all times reserve and keep available out of its authorized but unissued shares of Common Stock, solely for the purpose of issuance upon the conversion of the Series A Preferred Stock, such number of shares of Common Stock issuable upon the conversion of all outstanding shares of Series A Preferred Stock, and shall take all action required to increase the authorized number of shares of Common Stock if at any time there shall be insufficient authorized but unissued shares of Common Stock to permit such reservation or to permit the conversion of all outstanding shares of Series A Preferred Stock, including engaging in best efforts to obtain the requisite stockholder consent of any necessary amendment to the Certificate of Incorporation.

(e)     Taxes and Governmental Matters .

(i)  The issuance of certificates for shares of Common Stock pursuant to this  Section 8  shall be made without charge to the holders of such Series A Preferred Stock for any issuance tax in respect thereof or other cost incurred by the Corporation in connection with such conversion and the related issuance of shares of Common Stock;  provided  that the Corporation shall not, however, be required to pay any such tax that may be payable in respect of any transfer involved in the issuance or delivery of shares of Series A Preferred Stock, Common Stock or other securities in a name other than that in which the shares of Series A Preferred Stock with respect to which such shares or other securities are issued or delivered were registered, or in respect of any payment to any Person other than a payment to the registered holder thereof, and shall not be required to make any such issuance, delivery, or payment unless and until the Person otherwise entitled to such issuance, delivery or payment has paid to the Corporation the amount of any such tax or has established, to the Corporation’s satisfaction, that such tax has been paid or is not payable.

10

(ii)  The Corporation and the holders of the Series A Preferred Stock shall treat any conversion of the Series A Preferred Stock into Common Stock as a transaction described in Section 368(a)(1)(E) of the Internal Revenue Code of 1986, as amended, and the Treasury regulations promulgated thereunder, unless otherwise required pursuant to a change in applicable law occurring after the date hereof.

(f)     Other Obligations of the Corporation in Respect of Conversions.     Upon any conversion of any share of Series A Preferred Stock, the Corporation shall take all such actions as are necessary in order to assure that the Common Stock issuable upon such conversion shall be validly issued, fully paid and nonassessable, free and clear of all taxes, liens, charges and encumbrances with respect to the issuance thereof. The Corporation shall use reasonable best efforts to assist the holder of Series A Preferred Stock to ensure that shares of Common Stock issuable upon conversion may be so issued without violation of any applicable law or governmental regulation or any requirements of any domestic securities exchange upon which shares of Common Stock may be listed (except for official notice of issuance which shall be delivered as promptly as practicable by the Corporation upon each such issuance).

(g)     Fractional Shares.     The Corporation may not issue fractional interests in shares of Common Stock and, instead, shall pay to the holder in cash the then-current market value of any fraction of a share as promptly as practicable (and in any event no later than the date on which the certificate or certificates representing the Common Stock are issued) following the relevant Conversion Date.

(h)     Record Holder of Underlying Securities as of Conversion Date.     The Person or Persons entitled to receive the Common Stock issuable and/or cash payable upon conversion of Series A Preferred Stock on a Conversion Date shall be treated for all purposes as the record holder(s) of such shares of Common Stock as of the close of business on such Conversion Date. In the event that a holder of Series A Preferred Stock shall not by written notice designate the name in which shares of Common Stock to be issued (and/or cash payments in lieu of fractional shares to be paid) upon conversion of shares of Series A Preferred Stock should be registered or paid or the manner in which such shares should be delivered, the Corporation shall be entitled to register and deliver such shares, and make such payment, in the name of the holder shown on the records of the Corporation in any manner the Corporation in good faith deems reasonable.

Section 9.     Status of Converted, Redeemed or Otherwise Reacquired Shares.     Shares of Series A Preferred Stock converted, or redeemed or otherwise purchased or acquired by the Corporation, in accordance with this Certificate of Designations, shall be canceled and retired and shall not be reissued, sold or transferred, and the Corporation may thereafter take such appropriate action (without the need for stockholder action) as may be necessary to retire such shares and reduce the authorized number of shares of Series A Preferred Stock accordingly.

Section 10.     Preemptive Rights.     Holders of Series A Preferred Stock, in their capacities as such, shall not have any preemptive rights.

Section 11.     Transfers.     Notwithstanding anything to the contrary in this Certificate of Designations, a holder of Series A Preferred Stock may transfer all or any portion of shares of such Series A Preferred Stock to any Person who is not, at the time of such transfer, a Competitor. For the avoidance of doubt, the restrictions, conditions, and obligations contained in this Certificate of Designations to which such holder of Series A Preferred Stock is subject shall continue to be applicable to and binding upon the transferee(s) of such Series A Preferred Stock and the transferee(s) of such Series A Preferred Stock shall have agreed in writing to be bound by the provisions of this Certificate of Designations. To the extent any shares of Series A Preferred Stock transferred pursuant to this  Section 11  are converted into shares of Common Stock, such shares of Common Stock shall be entitled to all rights and remain subject to all restrictions, conditions, and obligations that are binding upon Common Stock at the time of such conversion.

Section 12.     Replacement.     Upon receipt of evidence reasonably satisfactory to the Corporation (an affidavit of the registered holder shall be satisfactory) of the ownership and the loss, theft, destruction or mutilation of any certificate evidencing one or more shares of any Series A Preferred Stock (or any Common Stock issued upon conversion thereof), and in the case of any such loss, theft or destruction, upon receipt of indemnity reasonably satisfactory to the Corporation (provided that if the holder is a financial institution or other institutional investor, its

11

own agreement shall be satisfactory), or, in the case of any such mutilation upon surrender of such certificate, the Corporation shall (at its expense) execute and deliver in lieu of such certificate a new certificate of like kind representing the number of shares of such Capital Stock represented by such lost, stolen, destroyed or mutilated certificate and dated the date of such lost, stolen, destroyed or mutilated certificate. Dividends shall accrue on any Series A Preferred Stock represented by such new certificate from the date with respect to which dividends have been fully paid on such lost, stolen, destroyed or mutilated certificate.

Section 13.     Withholding.     All payments and distributions (or deemed payments and distributions) on the shares of Series A Preferred Stock (and on the shares of Common Stock received upon the conversion of the Series A Preferred Stock), including, without limitation, issuance of shares of Common Stock upon conversion of the Series A Preferred Stock, shall be subject to withholding and backup withholding of tax to the extent required by law, subject to applicable exemptions, and amounts withheld, if any, shall be treated as received by holders. The Corporation shall cooperate as reasonably requested by the holders to avoid or minimize any withholding taxes that may become due in connection with any payment or distribution (or deemed payment or distribution) on the Series A Preferred Stock (or on shares of Common Stock received upon the conversion of the Series A Preferred Stock);  provided  that such cooperation does not cause material detriment to the Corporation or any of its Subsidiaries. The Corporation shall not withhold any U.S. federal income taxes with respect to a holder if such holder provides a properly completed and executed Internal Revenue Service Form W-9, unless otherwise required pursuant to a change in applicable law occurring after the date hereof. Any payments by the Corporation in respect of the Series A Preferred Stock shall be made out of funds legally available for payment thereof and shall only be made to the extent that the payment thereof would not cause the Corporation to be rendered insolvent or to violate any law to which the Corporation is subject.

Section 14.     Record Holders.     To the fullest extent permitted by applicable law, the Corporation may deem and treat the record holder of any share of the Series A Preferred Stock as the true and lawful owner thereof for all purposes, and the Corporation shall not be affected by any notice to the contrary.

Section 15.     Notices .

(a)     To Holders.     All public announcements, notices or communications to the holders of, or otherwise in respect of, the Series A Preferred Stock shall be given or delivered for purposes of this Certificate of Designations if given in writing and delivered in person or by first class mail, postage prepaid. All notices or communications shall also be given or delivered for purposes of this Certificate of Designations if given or delivered in such manner as may be permitted in this Certificate of Designations, in the Certificate of Incorporation or Bylaws or by applicable law or regulation. Furthermore, if the Series A Preferred Stock is issued in book-entry form through The Depository Trust Company or any similar facility, such notices may be given or delivered to the holders of the Series A Preferred Stock in any manner permitted by such facility and such notices will be deemed given and delivered in compliance with this Certificate of Designations.

(b)     To the Corporation.     All notices or communications to the Corporation shall be deemed given and delivered to the Corporation if given in writing and delivered in person or by first class mail, postage prepaid to the Corporation’s principal place of business.

Section 16.     Other Rights.     The shares of Series A Preferred Stock shall not have any rights, preferences, privileges or voting powers or relative, participating, optional or other special rights, or qualifications, limitations or restrictions thereof, other than as expressly set forth herein, in the Certificate of Incorporation or as provided by applicable law and regulation.

Section 17.     Remedies.     Except as set forth in the last sentence of  Section 8(a)  of this Certificate of Designations, the remedies available to the holders of Series A Preferred Stock under this Certificate of Designations shall be in addition to any other remedy to which such holders are entitled at law or in equity, and the election to pursue any such remedy shall not restrict, impair or otherwise limit the holders of Series A Preferred Stock from seeking to pursue any other remedy to which it is entitled under this Certificate of Designations, at law or in equity. Prior to conversion, payment of the Redemption Price in respect of a share of Series A Preferred Stock shall be in full satisfaction of any claim or remedy of a holder thereof in respect of such share of Series A Preferred Stock.

12

Section 18.     Tax Treatment of Series A Preferred Stock.     The Corporation and the holders shall treat the Series A Preferred Stock as equity for all applicable U.S. federal income, state and local income tax purposes, unless otherwise required by a change in applicable law occurring after the date hereof.

Section 19.     Non-Circumvention.     The Corporation shall not seek to avoid the observance or performance of any of the terms of this Certificate of Designations, including, without limitation, by amending its Certificate of Incorporation or Bylaws or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities.
