(a) As promptly as practicable after the date of this Agreement, the Company shall prepare and file with the SEC a prospectus supplement (including each amendment thereto, the “Prospectus Supplement”) to its existing registration statement on Form S-3 (File No. 333-139058) (including each amendment and supplement thereto, including the Prospectus Supplement, the “Registration Statement”), which shall register under the Securities Act the issuance of the Warrants and the shares of Common Stock to be issued upon exercise of the Warrants. The Company shall not permit any other securities to be included in the Prospectus Supplement. The Prospectus Supplement (and any amendments thereto) and any amendments to the Registration Statement proposed to be filed with the SEC after the date hereof shall be provided to the Investor and its counsel prior to their filing with the SEC, and the Investor and its counsel shall be given a reasonable opportunity to review and comment thereon.

(b) The Investor shall provide to the Company such information as the Company may reasonably require in connection with the preparation and filing of the Prospectus Supplement. At the time such information is provided and at the time the Prospectus Supplement is filed, no such information provided by the Investor shall include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading.

(c) At the time the Prospectus Supplement is filed, the Registration Statement shall comply in all material respects with the requirements as to the use and form of Form S-3, and the Registration Statement and any Company SEC Documents incorporated by reference therein shall not include an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, provided that the Company makes no such representation with respect to information provided to it by the Investor pursuant to Section 2.1(b). The Prospectus Supplement, as of its date, shall not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, provided that the Company makes no such representation with respect to information provided to it by the Investor pursuant to Section 2.1(b). The previous two sentences are referred to as the “10b-5 Representation.”

(d) Promptly following the filing of the Prospectus Supplement, the Company shall distribute copies of the Prospectus Supplement to the holders of record of Common Stock as of the Record Date, and thereafter promptly commence a rights offering on the following terms: (i) the Company shall distribute, at no charge, one (1) Warrant to each holder of record of Common Stock for each share of Common Stock held by such holder as of the Record Date; (ii) each whole Warrant shall entitle the holder thereof to purchase, at the election of such holder, one share of Common Stock at the Subscription Price (the “Basic Subscription Privilege”), thereby entitling such holders to subscribe for, in the aggregate, approximately 35.7 million (35,700,000) shares of Common Stock (the actual aggregate number, the “Aggregate Offered Shares”), provided that no fractional Warrants and no fractional shares of Common Stock shall be issued and the Subscription Price multiplied by the aggregate number of shares of Common Stock offered shall not exceed the aggregate offering amount described in the Prospectus Supplement; (iii) the offering shall remain open for at least thirteen (13) days, but no more than twenty (20) days (or such longer period as may be required by Law) (the “Subscription Period”); and (iv) each holder who fully exercises his Basic Subscription Privilege shall be entitled to subscribe for additional shares of Common Stock that were not subscribed for in the offering in an amount equal to up to 32% of the shares of Common Stock for which he was entitled to subscribe through his Basic Subscription Privilege (the “Oversubscription Privilege”), provided that if insufficient shares of Common Stock are available to satisfy all oversubscription requests, such requests shall be honored on a pro rata basis (such rights offering, the “Rights Offering”).

(e) The Company shall not amend any of the terms of the Rights Offering described in clauses (i) through (iv) of Section 2.1(d) or waive any material conditions to the closing of the Rights Offering without the prior written consent of the Investor. Subject to the terms and conditions of the Rights Offering, the Company shall effect the closing of the Rights Offering as promptly as practicable following the end of the Subscription Period.

(f) Notwithstanding anything in this Agreement to the contrary, the Company may terminate the Rights Offering, and fail to file or withdraw the Prospectus, at any time for any reason; provided that the failure to take commercially reasonable efforts to initiate or continue the Rights Offering shall be deemed to be a termination thereof for purposes of Section 9.1(a).

(g) The Company shall pay all of its expenses associated with the Registration Statement, the Prospectus Supplement, the Rights Offering and the other transactions contemplated hereby, including filing and printing fees, the fees and expenses of any subscription and information agents, the fees and expenses of its counsel, accounting fees and expenses and costs associated with clearing the Common Stock offered for sale under applicable state securities Laws.

Section 2.2 Backstop Commitment.

(a) The Investor shall purchase from the Company, and the Company shall issue and sell to the Investor, at a price per share equal to the Subscription Price, a number of shares of Common Stock (the “Backstop Commitment”) equal to the lesser of (i) the number of shares of Common Stock that will constitute 34.055% of the total number of outstanding shares of Common Stock immediately following the consummation of the Rights Offering and the issuance of shares of Common Stock pursuant to the Backstop Commitment and (ii) the number of shares of Common Stock equal to (x) the Aggregate Offered Shares minus (y) the number of shares of Common Stock subscribed for and purchased by the holders of record of Common Stock as of the Record Date pursuant to the Rights Offering. For the avoidance of doubt, the intention of the parties hereto (as is otherwise set forth in this Section 2.2(a) and in Section 3.1(a) hereof) is that the Investor will acquire a number of shares of Preferred Stock that upon conversion would result in the issuance of a number of shares of Common Stock equal to 19.9% of the total number of shares of Common Stock that will be outstanding immediately after the Backstop Closing, and will acquire a number of shares of Common Stock pursuant to the Backstop Commitment that will not exceed 34.055% of the total number of outstanding shares of Common Stock immediately after the Backstop Closing, and any reduction in the number of Acquired Shares to be purchased by the Investor pursuant to the terms hereof will be made to the number of shares of Common Stock to be purchased pursuant to the Backstop Commitment, and not to the number of shares of Preferred Stock to be purchased pursuant to the Preferred Stock Purchase Commitment. As soon as practicable (but not more than four Business Days) after the expiration of the Rights Offering, the Company shall deliver to the Investor a notice (the “Subscription Notice”) setting forth the number of shares of Common Stock subscribed for in the Rights Offering and, accordingly, the number of shares of Common Stock to be acquired by the Investor pursuant to the Backstop Commitment. The shares of Common Stock acquired by the Investor pursuant to the Backstop Commitment are collectively referred to as the “Backstop Shares.”

(b) The Backstop Commitment shall be subject to the terms and conditions of this Agreement and the completion of the following events; provided, however, that each of the following conditions shall be subject to waiver by the Investor in its sole discretion, as provided in Section 6.3:

(i) the consummation of the Rights Offering by the Company;

(ii) the purchase by the holders of record of Common Stock as of the Record Date pursuant to the Rights Offering of at least the number of shares of Common Stock that is equal to 25% of the Aggregate Offered Shares;

(d) Notwithstanding the foregoing, nothing in this Section 8.4 shall (i) prohibit or restrict any member of the Investor 13(d) Group from responding to any inquiries from any stockholders of the Company as to such member’s intention with respect to the voting of any Voting Stock of the Company Beneficially Owned by it so long as such response is consistent with the terms of this Agreement; (ii) restrict the right of each Investor Director on the Board or any committee thereof to vote on any matter as such individual believes appropriate in light of his or her duties as a director or committee member or restrict the manner in which an Investor Director may participate in his or her capacity as a director in deliberations or discussions at meetings of the Board or as a member of any committee thereof; (iii) prohibit the Investor 13(d) Group from Beneficially Owning Voting Stock of the Company issued as dividends or distributions in respect of, or issued upon conversion, exchange or exercise of, securities which the Investor 13(d) Group is permitted to Beneficially Own under this Agreement; (iv) prohibit or restrict any member of the Investor 13(d) Group from making a written proposal regarding an Acquisition Transaction directly to the Board, provided that (x) unless required by applicable Law, in no event may any member of the Investor 13(d) Group or any of its Representatives make such proposal public, (y) if, following its receipt of such written proposal, the Board determines to commence a process with respect to a potential Acquisition Transaction, the Company shall permit the Investor 13(d) Group to participate in such process and (z) if, pursuant to actions taken by the Board following its receipt of such written proposal, the Board determines to accept and recommend to the Company’s stockholders an Acquisition Transaction from another party (the “Alternate Acquisition Transaction”) that the Board believes to be superior to the Investor 13(d) Group’s proposed Acquisition Transaction, then the Investor 13(d) Group shall vote its Voting Stock of the Company in the same proportion as all other Voting Stock of the Company is voted with respect to such Alternate Acquisition Transaction or, in the case of a tender offer, tender its shares of Company stock in the same proportion as is tendered by all other holders of Company stock; or (v) prohibit any member of the Investor 13(d) Group from disclosing, in accordance with its obligations (if any) under the federal securities Laws or other applicable Law, its desire (if any) that the Company become the subject of an Acquisition Transaction. Notwithstanding anything to the contrary set forth in this Section 8.4, if, at any time following the consummation of a bankruptcy proceeding involving the Company, any Person (other than the Company) is permitted by Law or the bankruptcy court in which the proceeding is pending to propose a plan of reorganization for the Company, the Investor shall be permitted to propose a plan of reorganization for the Company, provided that no plan of reorganization shall be proposed by the Investor prior to the expiration or termination of the exclusivity period for the Company’s filing of a plan of reorganization, as such exclusivity period may be extended from time to time (it being understood and agreed that the Investor shall not object to any extension of the Company’s exclusivity period and shall not initiate or otherwise support any proceeding to terminate or shorten the length of the Company’s exclusivity period). The Investor hereby appoints the Company, its designees, and each of them individually, as the sole and exclusive attorneys and proxies of the Investor, with full power of substitution and re-substitution, to the full extent of the Investor’s right, with respect to any Voting Stock of the Company to be voted in accordance with the foregoing voting requirements related to Alternate Acquisition Transactions, and empowers such attorneys and proxies to exercise all voting rights of the Investor in accordance with the provisions of Section 8.4(d)(iv)(z) (including the power to execute and deliver written consents with respect to such Voting Stock) at any time prior to termination of this Section 8.4 at every annual, special or adjourned meeting of the stockholders of the Company and in every written consent in lieu of such meeting. The Investor confirms that this proxy is irrevocable, is coupled with an interest, and is granted in consideration of the Company entering into this Agreement.

Section 8.5 Notice Rights. From the Backstop Closing Date (or if the Backstop Closing does not occur, the Preferred Stock Closing Date) until the date on which the Investor 13(d) Group ceases to Beneficially Own 10% or more of the Common Stock of the Company (notwithstanding the definition of “Beneficially Own,” counting any shares of Preferred Stock on an as converted basis), the Company shall keep the Investor 13(d) Group informed, on a current basis, of any events, discussions, notices or changes with respect to any tax, criminal or regulatory investigation or action involving the Company or any of its Subsidiaries (in the case of tax or regulatory investigations or actions, other than ordinary course communications which could not reasonably be expected to be material to the Company, its Subsidiaries or the Investor), and shall reasonably cooperate with the Investor and its partners, Affiliates and Representatives in an effort to avoid or mitigate (with no adverse effect to the Company) any cost or regulatory consequences to the Investor and its partners and Affiliates that might arise from such investigation or action (including by allowing the Investor to review written submissions in advance and attend meetings with authorities and coordinating and providing assistance in connection with any meetings with authorities).

Section 8.6 Corporate Opportunities. In accordance with and as contemplated by Section 122, paragraph (17) of the DGCL (or any successor statute thereto), the Company hereby renounces, to the fullest extent permitted by law, any interest or expectancy in any business opportunity, transaction or other matter in which any of the Investor, its Affiliates, any Investor Director or any portfolio company in which the Investor or any of its Affiliates has an equity investment (the “Investor Group”) participates or desires or seeks to participate in and that involves any aspect of the energy business or industry, including without limitation, the midstream energy business (each, a “Business Opportunity”) other than a Business Opportunity that (i) is presented to an Investor Nominee solely in such person’s capacity as a director of the Company and with respect to which no member of the Investor Group (other than an Investor Director) independently receives notice or otherwise identifies such Business Opportunity or (ii) is identified by the Investor Group solely through the disclosure of information by or on behalf of the Company (each Business Opportunity other than those referred to in clauses (i) or (ii) are referred to as a “Renounced Business Opportunity”). No member of the Investor Group shall have any obligation to communicate or offer any Renounced Business Opportunity to the Company, and any member of the Investor Group may pursue a Renounced Business Opportunity. For the avoidance of doubt, the Company shall not be prohibited or restricted in any manner from pursuing or consummating any Business Opportunity with respect to which it has renounced any interest or expectancy as a result of this Section 8.6.

(a) Notwithstanding anything in this Agreement to the contrary, from and after the date hereof the Company agrees to indemnify and hold harmless the Investor, its Affiliates and each of their respective officers, directors, partners, employees, agents and Representatives (the “Investor Indemnified Parties”), to the fullest extent lawful, from and against any and all actions, suits, claims, proceedings, costs, losses, liabilities, damages, expenses (including reasonable and documented fees of counsel), amounts paid in settlement and other costs (collectively, “Losses”) arising out of or relating to (i) any material misstatement or omission in the Registration Statement or the Prospectus Supplement, provided that the Company shall not be liable in any such case to the extent that any such Loss arises out of or is based on statements made in reliance upon and in conformity with written information contained in either of the foregoing documents that was furnished to the Company by or on behalf of the Investor specifically for use therein, or (ii) claims, suits or proceedings challenging the authorization, execution, delivery, performance or termination by the Company of the Rights Offering, this Agreement, any Ancillary Agreement or any of the transactions contemplated hereby or thereby (other than any such Losses attributable to the acts, errors or omissions on the part of the Investor in violation of this Agreement). Notwithstanding the above, (A) other than with respect to Losses arising out of or incurred in connection with class action lawsuits brought against the Company and/or any of its directors or by any stockholders of the Company or a derivative action brought on behalf of the Company, in each case relating to matters for which the Investor Indemnified Parties are otherwise entitled to indemnification pursuant to clauses (i) or (ii) above (as to which there shall be indemnity hereunder), there shall be no indemnity hereunder in respect of any Losses resulting from any action that the Investor, its Affiliates or their respective transferees take, fail to take or propose to take (in each case, other than as required pursuant to this Agreement) in their capacity as a stockholder of the Company from and after the Backstop Closing Date and/or Preferred Stock Closing Date and (B) there shall be no indemnity hereunder in respect of any Losses resulting from any order, decree or injunction issued by any Governmental Entity restraining, enjoining or prohibiting any of the transactions contemplated by this Agreement under the HSR Act or any competition or merger control laws of other jurisdictions.

(b) Notwithstanding anything in this Agreement to the contrary, from and after the date hereof the Investor agrees to indemnify and hold harmless the Company, its Affiliates and each of their respective officers, directors, partners, employees, agents and Representatives (the “Company Indemnified Parties”), to the fullest extent lawful, from and against any and all Losses arising out of or relating to (i) any material misstatement or omission in the Prospectus Supplement to the extent that any such Loss arises out of or is based on statements made in reliance upon and in conformity with written information contained in either of the foregoing documents that was furnished to the Company by or on behalf of the Investor specifically for use therein, or (ii) claims, suits or proceedings challenging the authorization, execution, delivery, performance or termination by the Investor of this Agreement, any Ancillary Agreement or any of the transactions contemplated hereby or thereby (other than any such Losses attributable to the acts, errors or omissions on the part of the Company in violation of this Agreement).

Such notice shall describe in reasonable detail such claim. In case any such action, suit, claim or proceeding is brought against an Indemnified Party, the Indemnified Party shall be entitled to hire, at its own expense, separate counsel and participate in the defense thereof, provided, however, that the Indemnifying Party shall be entitled to assume and conduct the defense, unless the Indemnifying determines otherwise and following such determination the Indemnified Party assumes responsibility for conducting the defense (in which case the Indemnifying Party shall be liable for any reasonable and documented legal fees and expenses of one law firm retained by the Indemnified Party and other reasonable and documented out of pocket expenses reasonably incurred by the Indemnified Party in connection with assuming and conducting the defense), and provided, further, that if the Indemnifying Party is conducting the defense the Indemnifying Party shall be liable for any reasonable and documented legal fees and expenses of one law firm retained by the Indemnified Party and other reasonable and documented out of pocket expenses reasonably incurred by the Indemnified Party in connection with such claim if the Indemnified Party reasonably shall have concluded (upon advice of its counsel) that there are one or more legal defenses available to the Indemnified Party that are not available to the Indemnifying Party or the Indemnified Party shall have concluded (upon advice of its counsel) that, with respect to such claim, the Indemnified Party and the Indemnifying Party have different, conflicting or adverse legal positions or interests. If the Indemnifying Party assumes the defense of any claim, all Indemnified Parties shall thereafter deliver to the Indemnifying Party copies of all notices and documents (including court papers) received by the Indemnified Party relating to the claim, and any Indemnified Party shall cooperate in the defense or prosecution of such claim. Such cooperation shall include the retention and (upon the Indemnifying Party’s request) the provision to the Indemnifying Party of records and information that are reasonably relevant to such claim and making representatives available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. The Indemnifying Party shall not be liable for any settlement of any action, suit, claim or proceeding effected without its written consent. The Indemnifying Party will not, without the Indemnified Party’s prior written consent, settle or compromise any claim or consent to entry of any judgment in respect thereof in any pending or threatened action, suit, claim or proceeding in respect of which indemnification has been sought hereunder unless such settlement or compromise includes an unconditional release of such Indemnified Party from all liability arising out of such action, suit, claim or proceeding.

THESE SHARES ARE SUBJECT TO RESTRICTIONS PURSUANT TO THE INVESTMENT AGREEMENT DATED MAY 20, 2009 AMONG THE COMPANY AND LIME ROCK PARTNERS V, L.P., AS AMENDED FROM TIME TO TIME.

4. Dividends.

(a) Holders of Preferred Stock shall be entitled to receive, when, as and if declared by the Board of Directors, out of funds legally available for the payment of dividends, cumulative cash dividends on each Outstanding share of Preferred Stock at the Annual Dividend Rate, calculated as set forth below; provided, however, that such holders will not be entitled to receive any dividends that may be declared by the Board of Directors on the Common Stock, unless such holders’ shares of Preferred Stock have been converted to Common Stock as set forth in Section 6 hereof prior to or on the Record Date for the payment of such dividends. Such dividends shall be payable in arrears in equal amounts quarterly on each Dividend Payment Date, beginning September 30, 2009, in preference to and in priority over dividends on any Junior Stock but subject to the rights of any holders of Senior Stock or Parity Stock.

(b) Dividends on each share of Preferred Stock shall be cumulative from the initial date of issuance of such share, shall cumulate on a daily basis and, if not paid on the next Dividend Payment Date, shall, until paid, cumulate additional dividends on such cumulated but unpaid dividends (and shall compound as of each Dividend Payment Date) at the Annual Dividend Rate, regardless of whether funds of the Corporation are legally available for the payment of such dividends and regardless of whether the Board of Directors declares the dividends; provided, however, that on the third anniversary of the Original Issue Date, dividends on the Preferred Stock shall cumulate only upon dividends that were accumulated and unpaid, if any, as of the third anniversary of the Original Issue Date, and thereafter, holders of Preferred Stock shall not be entitled to receive any dividends on the Preferred Stock, other than dividends that were accumulated and unpaid immediately prior to the third anniversary of the Original Issue Date and dividends that continue to cumulate upon such unpaid dividends. Each dividend on the Preferred Stock shall be payable to the holders of record of shares of the Preferred Stock, as they appear on the Corporation’s stock register at the close of business on a Record Date. Accumulated and unpaid dividends for any past Dividend Periods may be declared and paid at any time, without reference to any Dividend Payment Date, to holders of record on such date, not more than 60 nor less than 10 days preceding the payment date thereof, as may be fixed by the Board of Directors.

(c) The amount of dividends payable for each full Dividend Period on each share of Preferred Stock shall be the product of (a) one-fourth of the Annual Dividend Rate multiplied by (b) the Liquidation Preference. The amount of dividends payable on the Preferred Stock for the initial Dividend Period, or for any other period shorter or longer than a full Dividend Period (or amounts determined with respect thereto), shall be computed on the basis of a 360-day year consisting of twelve 30-day months. Holders of Preferred Stock shall not be entitled to any dividends, whether payable in cash, property or stock, in excess of cumulative dividends, as herein provided, on the Preferred Stock.

(d) No dividend shall be declared or paid, or funds set apart for the payment of any dividend or other distribution, whether in cash, obligations or shares of Capital Stock of the Corporation or other property, directly or indirectly, upon any shares of Junior Stock or Parity Stock, nor shall any shares of Junior Stock or Parity Stock be redeemed, repurchased or otherwise acquired for consideration by the Corporation or any of its subsidiaries through a sinking fund or otherwise, in each case unless all accumulated and unpaid dividends through the most recent Dividend Payment Date (regardless of whether there are funds of the Corporation legally available for the payment of dividends) on the shares of Preferred Stock and any Parity Stock for all preceding Dividend Periods have been paid in full or set apart for payment; provided, however, that, notwithstanding any provisions of this Section 4(d) to the contrary, the Corporation or any of its subsidiaries may redeem, repurchase or otherwise acquire for consideration Junior Stock or Parity Stock, if the consideration for such redemption, repurchase or other acquisition is solely Junior Stock. Furthermore, for the avoidance of doubt, the foregoing provisions of this Section 4(d) shall not apply to any shares of Junior Stock or Parity Stock surrendered to the Company upon a “cashless” exercise of stock options or withheld upon the exercise of stock options or the vesting of restricted stock to satisfy applicable withholding tax obligations. When dividends are not paid in full, as aforesaid, upon the shares of Preferred Stock, all dividends declared on the Preferred Stock and any other Parity Stock shall be paid pro rata so that the amount of dividends so declared on the shares of Preferred Stock and each such other class or series of Parity Stock shall in all cases bear to each other the same ratio as accumulated dividends on the shares of Preferred Stock and such class or series of Parity Stock bear to each other.

5. Liquidation Preference.

(a) In the event of any liquidation, dissolution or winding-up of the Corporation resulting in a payment or distribution of assets to the holders of any class or series of the Capital Stock of the Corporation, whether voluntary or involuntary, before any payment or distribution of the Corporation’s assets (whether capital or surplus) shall be made to or set apart for the holders of Junior Stock, but after any payments or distributions are made on any of the Corporation’s indebtedness and to holders of Senior Stock, holders of Preferred Stock shall be entitled to receive the Adjusted Liquidation Preference thereof plus an amount equal to all dividends (regardless of whether declared) accumulated and unpaid thereon to the date of final payment or distribution to such holders, but shall not be entitled to any further payment or other participation in any distribution of the assets of the Corporation. If, upon any liquidation, dissolution or winding-up of the Corporation, whether voluntary or involuntary, the Corporation’s assets, or proceeds thereof, distributable among the holders of Preferred Stock are insufficient to pay in full the preferential amount aforesaid and liquidating payments on any Parity Stock, then such assets, or the proceeds thereof, shall be distributed among the holders of the Preferred Stock and any other Parity Stock equally and ratably in proportion to the respective amounts that would be payable on such shares of Preferred Stock and any such other Parity Stock if all amounts payable thereon were paid in full.

(b) Neither the voluntary sale, conveyance, exchange or transfer, for cash, shares of stock, securities or other consideration, of all or substantially all of the Corporation’s property or assets, nor the consolidation, merger or amalgamation of the Corporation with or into any corporation or the consolidation, merger or amalgamation of any corporation with or into the Corporation shall be deemed to be a voluntary or involuntary liquidation, dissolution or winding-up of the Corporation.

(c) Subject to the rights of the holders of any Parity Stock, after payment has been made in full to the holders of the Preferred Stock, as provided in this Section 5, holders of Junior Stock shall, subject to the respective terms and provisions (if any) applying thereto, be entitled to receive any and all assets remaining to be paid or distributed, and the holders of Preferred Stock shall not be entitled to share therein.

6. Conversion.

(a) Right to Convert. Each share of Preferred Stock shall be convertible, at any time, in accordance with, and subject to, this Section 6 into a number of fully paid and non-assessable shares of Common Stock equal to the Conversion Rate in effect at such time. Notwithstanding any provision hereof, prior to the earlier of the third anniversary of the Original Issue Date or the Standstill Expiration Date (as defined in the Investment Agreement), no share of Preferred Stock shall be convertible into shares of Common Stock unless, (i) a member of the applicable Investor Group provides a written certification to the Corporation specifying the total number of issued and outstanding shares of Common Stock Beneficially Owned by such Investor Group and (ii) immediately after giving effect to such conversion, such Investor Group would not Beneficially Own a number of shares of Common Stock exceeding 35 percent (35%) of the total number of issued and outstanding shares of Common Stock held by all stockholders; provided, however, this restriction on conversion shall not apply if the Corporation has given prior written consent to such conversion, which consent may be given at the Corporation’s sole discretion, except as otherwise provided in the Investment Agreement.

(b) Conversion Procedures.

(i) Conversion of shares of the Preferred Stock may be effected by any holder thereof upon the surrender to the Corporation, at the principal office of the Corporation or at the office of the Conversion Agent as may be designated by the Board of Directors, of the certificate or certificates for such shares of the Preferred Stock to be converted accompanied by a complete and manually signed Notice of Conversion (as set forth in the form of Preferred Stock certificate attached hereto as Exhibit A) along with (A) appropriate endorsements and transfer documents as required by the Registrar or Conversion Agent, (B) if required pursuant to Section 6(c), funds equal to the amount specified in such Section. In case such Notice of Conversion shall specify a name or names other than that of such holder, such notice shall be accompanied by payment of all transfer taxes payable upon the issuance of shares of Common Stock in such name or names and (C) the written certification referred to in Section 6(a) above. Other than such taxes, the Corporation shall pay any documentary, stamp or similar issue or transfer taxes that may be payable in respect of any issuance or delivery of shares of Common Stock upon conversion of shares of the Preferred Stock pursuant hereto. The conversion of the Preferred Stock will be deemed to have been made as of the close of business on the date (the “Conversion Date”) such certificate or certificates have been surrendered and the receipt of such Notice of Conversion and payment of all required transfer taxes, if any (or the demonstration to the satisfaction of the Corporation that such taxes have been paid). As promptly as practicable following the Conversion Date, the Corporation shall deliver or cause to be delivered (1) certificates representing the whole number of validly issued, fully paid and nonassessable full shares of Common Stock to which the holder of shares of the Preferred Stock being converted (or such holder’s transferee) shall be entitled, and (2) if less than the full number of shares of the Preferred Stock evidenced by the surrendered certificate or certificates is being converted, a new certificate or certificates, of like tenor, for the number of shares evidenced by such surrendered certificate or certificates less the number of shares of Preferred Stock being converted, along with cash payment for any fractional shares. As of the close of business on the Conversion Date, the rights of the holder of the Preferred Stock as to the shares being converted shall cease except for the right to receive shares of Common Stock and any cash payment described in Section 6(c) below, and the Person entitled to receive the shares of Common Stock shall be treated for all purposes as having become the record holder of such shares of Common Stock at such time.

(ii) Anything herein to the contrary notwithstanding, in the case of Global Preferred Shares, Notices of Conversion may be delivered to, and shares of the Preferred Stock representing beneficial interests in respect of such Global Preferred Shares shall be surrendered for conversion in accordance with the applicable procedures of, the Depositary as in effect from time to time.

(c) Dividend and Other Payments Upon Conversion. If a holder of shares of Preferred Stock exercises conversion rights, such holder shall be entitled to receive within five Business Days after the Conversion Date, to the extent legally permitted, an amount equal to all accumulated and unpaid dividends on the converted shares of Preferred Stock, whether or not declared prior to that date, through the Conversion Date, and such shares will cease to accumulate any dividends as of the end of the day immediately preceding the Conversion Date. If a holder of shares of Preferred Stock exercises conversion rights during the period commencing on the close of business on any Record Date corresponding to a Dividend Payment Date and ending at the close of business on the Business Day immediately preceding such Dividend Payment Date, the holder on such Dividend Record Date shall receive the dividends declared and paid with respect to such Dividend Payment Date, but the amount that the holder of shares of Preferred Stock exercising conversion rights during such period shall be entitled to receive in respect of accumulated and unpaid dividends shall be reduced by the amount of dividends that will be paid to the holder as of such Record Date of such shares on such Dividend Payment Date (and if such accumulated and unpaid dividends are less than such amount of dividends to be so paid on the Dividend Payment Date, then the shares of Preferred Stock surrendered for conversion must be accompanied by a payment to the Corporation in cash of an amount equal to such shortfall). A holder of shares of the Preferred Stock on a Record Date who converts such shares into shares of Common Stock on the corresponding Dividend Payment Date shall be entitled to receive the dividend payable on such shares of the Preferred Stock on such Dividend Payment Date. To the extent the Corporation is not legally permitted to pay all amounts contemplated by this Section 6(c) upon such conversion, then the Corporation shall pay such amounts as soon as it may legally do so.

(d) Fractional Shares. In connection with the conversion of any shares of the Preferred Stock, no fractional shares of Common Stock shall be issued, but the Corporation shall pay a cash adjustment in respect of any fractional interest in an amount equal to the fractional interest multiplied by the Closing Sale Price of the Common Stock on the Conversion Date, rounded to the nearest whole cent.

(e) Total Shares. If more than one share of the Preferred Stock shall be surrendered for conversion by the same holder at the same time, the number of whole shares of, and fractional interests, if any, in, Common Stock issuable on conversion of those shares shall be computed on the basis of the total number of shares of the Preferred Stock so surrendered.

(f) Reservation of Shares; Shares to be Fully Paid; Compliance with Governmental Requirements; Listing of Common Stock. The Corporation shall:

(i) at all times from and after the Original Issue Date, reserve and keep available, free from preemptive rights, for issuance upon the conversion of shares of the Preferred Stock pursuant to the terms of this Certificate, such number of its authorized but unissued shares of Common Stock as shall from time to time be sufficient to permit the conversion of all Outstanding shares of the Preferred Stock;

(ii) prior to the delivery of any securities that the Corporation shall be obligated to deliver upon conversion of the Preferred Stock, comply with all applicable federal and state laws and regulations that require action to be taken by the Corporation (including, without limitation, the registration or approval, if required, of any shares of Common Stock to be provided for the purpose of conversion of the Preferred Stock hereunder); and

(iii) ensure that all shares of Common Stock delivered upon conversion of the Preferred Stock will, upon delivery, be duly and validly issued and fully paid and nonassessable, free of all liens and charges and not subject to any preemptive rights.

7. Conversion Rate Adjustments. The Conversion Rate shall be adjusted from time to time by the Corporation in accordance with the provisions of this Section 7.

(a) If the Corporation shall hereafter pay a dividend or make a distribution to all holders of the outstanding Common Stock in shares of Common Stock, the Conversion Rate shall be increased by multiplying such Conversion Rate by a fraction,

(i) the numerator of which shall be the sum of the number of shares of Common Stock outstanding at the close of business on such Record Date and the total number of shares of Common Stock constituting such dividend or other distribution; and

(ii) the denominator of which shall be the number of shares of Common Stock outstanding at the close of business on such Record Date.

Such increase shall become effective immediately after the opening of business on the day following such Record Date. If any dividend or distribution of the type described in this Section 7(a) is declared but not so paid or made, the Conversion Rate shall again be adjusted to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

(b) If the Corporation shall issue rights or warrants to all holders of any class of Common Stock entitling them (for a period expiring within forty-five (45) days after the Record Date) to subscribe for or purchase shares of Common Stock (or securities convertible into Common Stock) at a price per share (or having a conversion price per share) less than the Closing Sale Price of a share of Common Stock on the Trading Day immediately preceding the Record Date, the Conversion Rate shall be adjusted by multiplying the Conversion Rate in effect immediately prior to such Record Date by a fraction,

(i) the numerator of which shall be the number of shares of Common Stock outstanding at the close of business on such Record Date plus the total number of shares of Common Stock so offered for subscription or purchase (or into which the convertible securities so offered are convertible); and

(ii) the denominator of which shall be the number of shares of Common Stock outstanding at the close of business on such Record Date plus the number of shares which the aggregate offering price of the total number of shares so offered for subscription or purchase (or the aggregate conversion price of the convertible securities so offered) would purchase at such Closing Sale Price.

Such adjustment shall become effective immediately after the opening of business on the day following such Record Date. To the extent that shares of Common Stock (or securities convertible into Common Stock) are not delivered pursuant to such rights or warrants, upon the expiration or termination of such rights or warrants, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had the adjustment made upon the issuance of such rights or warrants been made on the basis of delivery of only the number of shares of Common Stock (or securities convertible into Common Stock) actually delivered. If such rights or warrants are not so issued, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such Record Date had not been fixed. In determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such Closing Sale Price, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by the Corporation for such rights or warrants and any amount payable on exercise or conversion thereof, the Fair Market Value of such consideration, if other than cash, to be determined in good faith by the Board of Directors. Notwithstanding the foregoing, no adjustment shall be made to the Conversion Rate pursuant to this Section 7(b) for the rights of holders of Common Stock to participate in the Corporation’s rights offering contemplated in its Prospectus Supplement dated May [_____], 2009.

(c) If the outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately increased, and conversely, in the event outstanding shares of Common Stock shall be combined into a smaller number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately reduced, such increase or reduction, as the case may be, to become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective.

(d) If the Corporation shall, by dividend or otherwise, distribute to all holders of its Common Stock shares of any class of Capital Stock of the Corporation (other than any dividends or distributions to which Section 7(a) applies) or evidences of its indebtedness or assets (including securities, but excluding (i) any rights or warrants referred to in 7(b) or (ii) any dividend or distribution (x) paid exclusively in cash or (y) referred to in Section 7(a) or Section 7(g) (any of the foregoing hereinafter referred to in this Section 7(d) as the “Distributed Property”), then, in each such case, the Conversion Rate shall be adjusted so that the same shall be equal to the rate determined by multiplying the Conversion Rate in effect on the Record Date with respect to such distribution by a fraction,

(i) the numerator of which shall be the Current Market Price on such Record Date; and

(ii) the denominator of which shall be the Current Market Price on such Record Date less the Fair Market Value (as determined in good faith by the Board of Directors, whose determination shall be described in a resolution of the Board of Directors) on such Record Date of the portion of the Distributed Property applicable to one share of Common Stock (determined on the basis of the number of shares of the Common Stock outstanding on such Record Date).

Such adjustment shall become effective immediately after the opening of business on the day following such Record Date; provided that if the then Fair Market Value (as so determined by the Board of Directors) of the portion of the Distributed Property applicable to one share of Common Stock is equal to or greater than the Current Market Price on the Record Date, in lieu of the foregoing adjustment, adequate provision shall be made so that each holder of Preferred Stock shall have the right to receive upon conversion the amount of Distributed Property such holder would have received had such holder converted each share of its Preferred Stock on the Record Date. To the extent that any of the Distributed Property is not distributed, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had the adjustment made been made on the basis of only the Distributed Property actually distributed. If such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. If the Board of Directors determines the Fair Market Value of any distribution for purposes of this Section 7(d) by reference to the trading market for any securities, it must in doing so consider the prices in such market over the same period used in computing the Current Market Price on the applicable Record Date.

Subject to the provisions of Section 10 hereof, rights or warrants (including rights under any Rights Plan) distributed by the Corporation to all holders of Common Stock entitling the holders thereof to subscribe for or purchase shares of the Corporation’s Capital Stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such shares of Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 7(d) (and no adjustment to the Conversion Rate under this Section 7(d) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 7(d). If any such right or warrant, including any such existing rights or warrants distributed prior to the date of this Certificate, are subject to events, upon the occurrence of which such rights or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and record date with respect to new rights or warrants with such rights (and a termination or expiration of the existing rights or warrants without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 7(d) was made, (1) in the case of any such rights or warrants that shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Rate shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder or holders of Common Stock with respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights or warrants that shall have expired or been terminated without exercise thereof, the Conversion Rate shall be readjusted as if such expired or terminated rights and warrants had not been issued.

For purposes of this Section 7(d), Section 7(a) and Section 7(b), any dividend or distribution to which this Section 7(d) is applicable that also includes shares of Common Stock, or rights or warrants to subscribe for or purchase shares of Common Stock (or both), shall be deemed instead to be (1) a dividend or distribution of the evidences of indebtedness, assets or shares of Capital Stock other than such shares of Common Stock or rights or warrants, as to which any Conversion Rate adjustment required by this Section 7(d) with respect to such dividend or distribution shall then be made, immediately followed by (2) a dividend or distribution of such shares of Common Stock or such rights or warrants, as to which any further Conversion Rate adjustment required by Sections 7(a) and 7(b) with respect to such dividend or distribution shall then be made, except any shares of Common Stock included in such dividend or distribution shall not be deemed “outstanding at the close of business on such Record Date” within the meaning of Sections 7(a) and 7(b).

(e) If the Corporation shall, by dividend or otherwise, distribute to all holders of its Common Stock cash, excluding any dividend or distribution in connection with the liquidation, dissolution or winding-up of the Corporation, whether voluntary or involuntary, then, in such case, the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the close of business on such Record Date by a fraction,

(i) the numerator of which shall be the Current Market Price on such Record Date; and

(ii) the denominator of which shall be the Current Market Price on such Record Date less the amount of cash so distributed applicable to one share of Common Stock.

Such adjustment shall be effective immediately after the opening of business on the day following the Record Date; provided that if the portion of the cash so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price on the Record Date, in lieu of the foregoing adjustment, adequate provision shall be made so that each holder of Preferred Stock shall have the right to receive upon conversion the amount of cash such holder would have received had such holder converted each share of Preferred Stock on the Record Date. To the extent that such dividend or distribution is not made, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had the adjustment made been made on the basis of only the dividend or distribution actually made. If such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

(f) If a tender or exchange offer made by the Corporation or any Subsidiary for all or any portion of the Common Stock shall require the payment to stockholders of consideration per share of Common Stock having a Fair Market Value (as determined in good faith by the Board of Directors, whose determination shall be described in a resolution of the Board of Directors) that, as of the last time (the “Expiration Time”) tenders or exchanges may be made pursuant to such tender or exchange offer, exceeds the Closing Sale Price of a share of Common Stock on the Trading Day next succeeding the Expiration Time, the Conversion Rate shall be increased by multiplying the Conversion Rate in effect immediately prior to the Expiration Time by a fraction,

(i) the numerator of which shall be the sum of (x) the Fair Market Value (determined as aforesaid) of the aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of all shares validly tendered or exchanged and not withdrawn as of the Expiration Time (the shares deemed so accepted up to any such maximum, being referred to as the “Purchased Shares”) and (y) the product of the number of shares of Common Stock outstanding (less any Purchased Shares) at the Expiration Time and the Closing Sale Price of a share of Common Stock on the Trading Day next succeeding the Expiration Time; and

(ii) the denominator of which shall be the number of shares of Common Stock outstanding (including any Purchased Shares) at the Expiration Time multiplied by the Closing Sale Price of a share of Common Stock on the Trading Day next succeeding the Expiration Time.

Such adjustment shall become effective immediately after the opening of business on the day following the Expiration Time. In the event that the Corporation or any such Subsidiary, as the case may be, is obligated to purchase shares pursuant to any such tender or exchange offer, but the Corporation or any such Subsidiary, as the case may be, is permanently prevented by applicable law from effecting any such purchases or all such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such tender or exchange offer had not been made.

(g) If the Corporation pays a dividend or makes a distribution to all or substantially all holders of its Common Stock consisting of Capital Stock of any class or series, or similar equity interests, of or relating to a Subsidiary or other business unit of the Corporation, unless the Corporation distributes such Capital Stock or equity interests to holders of the Preferred Stock in such distribution on the same basis as they would have received had such holders converted their shares of Preferred Stock into shares of Common Stock immediately prior to such distributions, the Conversion Rate shall be increased by multiplying the Conversion Rate in effect on the Record Date with respect to such distribution by a fraction,

(i) the numerator of which shall be the sum of (A) the average of the Closing Sale Prices of the Common Stock for the 10 Trading Days commencing on and including the fifth Trading Day after the date on which “ex-dividend trading” commences for such dividend or distribution on The New York Stock Exchange or such other national or regional exchange or market on which such securities are then listed or quoted (the “Ex-Dividend Date”) plus (B) the Fair Market Value of the securities distributed in respect of each share of Common Stock, which shall equal the number of securities distributed in respect of each share of Common Stock multiplied by the average of the Closing Sale Prices of those distributed securities for the 10 Trading Days commencing on and including the fifth Trading Day after the Ex-Dividend Date; and

(ii) the denominator of which shall be the average of the Closing Sale Prices of the Common Stock for the 10 Trading Days commencing on and including the fifth Trading Day after the Ex-Dividend Date.

Such adjustment shall become effective immediately after the opening of business on the day following the 15th Trading Day after the Ex-Dividend Date.

(h) If the Corporation issues or sells any Common Stock (other than (1) shares of Common Stock to be issued to employees, officers and directors of the Corporation, together with any such shares that are repurchased by the Corporation and reissued to any such employee, officer or director, and (2) any issuances or sales to which Sections 7(a), 7(b), 7(c) or 7(d) applies) without consideration or for a consideration per share less than the Conversion Price in effect immediately prior to such issuance or sale, the Conversion Rate in effect immediately prior to each such issuance or sale will immediately (except as provided below), be adjusted so that the same shall be equal to the rate determined by multiplying the Conversion Rate in effect immediately prior to such issuance or sale by a fraction, (i) the numerator of which shall be the number of shares of Common Stock outstanding immediately after such issue or sale; and (ii) the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance or sale plus the number of shares of Common Stock which the aggregate consideration received by the Corporation for the total number of such additional shares of Common Stock so issued or sold would purchase at the Conversion Price in effect immediately prior to such issuance or sale. For the purposes of any adjustment of the Conversion Rate pursuant to this Section 7(h), the following provisions shall be applicable:

(i) in the case of the issuance of Common Stock for cash, the amount of the consideration received by the Corporation shall be deemed to be the amount of the cash proceeds received by the Corporation for such Common Stock before deducting therefrom any discounts or commissions allowed, paid or incurred by the Corporation for any underwriting or otherwise in connection with the issuance and sale thereof;

(ii) in the case of the issuance of Common Stock (otherwise than upon the conversion of shares of Capital Stock or other securities of the Corporation) for a consideration in whole or in part other than cash, including securities acquired in exchange therefore (other than securities by their terms so exchangeable), the consideration other than cash shall be deemed to be the fair value thereof as determined in good faith by the Board, irrespective of any accounting treatment;

(iii) in the case of the issuance of (a) options, warrants or other rights to purchase or acquire Common Stock (whether or not at the time exercisable), (b) securities (including without limitation, the Preferred Stock) by their terms convertible into or exchangeable for Common Stock (whether or not at the time so convertible or exchangeable) or options, warrants or rights to purchase such convertible or exchangeable securities (whether or not at the time exercisable):

(A) the aggregate maximum number of shares of Common Stock deliverable upon exercise of such options, warrants or other rights to purchase or acquire Common Stock shall be deemed to have been issued at the time such options, warrants or rights are issued and for a consideration equal to the consideration, if any, received by the Corporation upon the issuance of such options, warrants or rights plus the minimum purchase price provided in such options, warrants or rights for the Common Stock covered thereby;

(B) the aggregate maximum number of shares of Common Stock deliverable upon conversion of or in exchange for any such convertible or exchangeable securities, or upon the exercise of options, warrants or other rights to purchase or acquire such convertible or exchangeable securities and the subsequent conversion or exchange thereof, shall be deemed to have been issued at the time such securities were issued or such options, warrants or rights were issued and for a consideration equal to the consideration, if any, received by the Corporation for any such securities and related options, warrants or rights (excluding any cash received on account of accrued interest or accrued dividends), plus the additional consideration, if any, to be received by the Corporation upon the conversion or exchange of such securities, or upon the exercise of any related options, warrants or rights to purchase or acquire such convertible or exchangeable securities and the subsequent conversion or exchange thereof;

(C) on any change in the number of shares of Common Stock deliverable upon exercise of any such options, warrants or rights or conversion or exchange of such convertible or exchangeable securities or any change in the consideration to be received by the Corporation upon such exercise, conversion or exchange, but excluding changes resulting from the anti-dilution provisions thereof (to the extent comparable to the anti-dilution provisions contained herein), the Conversion Rate as then in effect shall forthwith be readjusted to such Conversion Rate as would have been obtained had an adjustment been made upon the issuance of such options, warrants or rights not exercised prior to such change, or of such convertible or exchangeable securities not converted or exchanged prior to such change, upon the basis of such change;

(D) on the expiration or cancellation of any such options, warrants or rights (without exercise), or the termination of the right to convert or exchange such convertible or exchangeable securities (without exercise), if the Conversion Rate shall have been adjusted upon the issuance thereof, the Conversion Rate shall forthwith be readjusted to such Conversion Rate as would have been obtained had an adjustment been made upon the issuance of such options, warrants, rights or such convertible or exchangeable securities on the basis of the issuance of only the number of shares of Common Stock actually issued upon the exercise of such options, warrants or rights, or upon the conversion or exchange of such convertible or exchangeable securities; and

(E) if the Conversion Rate shall have been adjusted upon the issuance of any such options, warrants, rights or convertible or exchangeable securities, no further adjustment of the Conversion Rate shall be made for the actual issuance of Common Stock upon the exercise, conversion or exchange thereof; provided, however, that no decrease in the Conversion Rate shall be made pursuant to subclauses (A) or (B) of this Section 7(h)(iii).

(iv) All shares of Common Stock that the Corporation has reserved for issuance to employees, officers and directors of the Corporation under the then outstanding options to acquire Common Stock shall be deemed to be outstanding to the extent, but only to the extent, that such reserved shares do not exceed five percent (5%) of the then outstanding shares of Common Stock (excluding any such deemed outstanding shares).

(i) To the fullest extent permitted by law, the Corporation may make such increases in the Conversion Rate in addition to those required by this Section 7 as the Board of Directors considers to be advisable to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock resulting from any dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for income tax purposes. To the fullest extent permitted by applicable law, the Corporation from time to time may increase the Conversion Rate by any amount for any period of time if the period is at least 20 days and the increase is irrevocable during the period and the Board of Directors determines in good faith that such increase would be in the best interest of the Corporation, which determination shall be conclusive. Whenever the Conversion Rate is increased pursuant to the preceding sentence, the Corporation shall mail to each holder of the Preferred Stock at the address of such holder as it appears in the stock register a notice of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect.

(j) No adjustment in the Conversion Rate (other than any adjustment pursuant to Section 7(e) above) shall be required unless such adjustment would require an increase or decrease of at least one-half of one percent (0.5%) in the Conversion Rate then in effect; provided, however, that any adjustments that by reason of this Section 7(j) are not required to be made shall be carried forward and taken into account in any subsequent adjustment; provided further, that with respect to adjustments to be made to the Conversion Price in connection with cash dividends paid by the Corporation, the Corporation shall make such adjustments, regardless of whether such aggregate adjustments amount to one-half of one percent (0.5%) or more of the Conversion Price. All calculations under this Section 7 shall be made by the Corporation and shall be made to the nearest cent or to the nearest one-ten thousandth (1/10,000) of a share, as the case may be. No adjustment need be made, except as set forth in this Section 7, for any issuance of Common Stock or securities convertible, exercisable or exchangeable into Common Stock. Interest will not accrue on any cash into which the Preferred Stock may be convertible.

(k) Whenever the Conversion Rate is adjusted as herein provided (except for adjustments pursuant to Section 7(e) hereof that in the aggregate are less than one-half of one percent (0.5%)), the Corporation shall promptly file with the Conversion Agent an Officer’s certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a responsible officer of the Conversion Agent shall have received such Officer’s certificate, the Conversion Agent shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume that the last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Corporation shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment becomes effective and shall mail such notice of such adjustment of the Conversion Rate to each holder of Preferred Stock at its last address appearing in the stock register within twenty (20) days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

(l) For purposes of this Section 7, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Corporation, unless such treasury shares participate in any distribution or dividend that requires an adjustment pursuant to this Section 7, but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock.

8. Mandatory Conversion.

(a) At any time on or after the fifth anniversary of the Original Issue Date, the Corporation shall have the right, at its option, to cause the Preferred Stock, in whole but not in part, to be automatically converted into that number of whole, fully paid and non-assessable shares of Common Stock for each share of Preferred Stock equal to the Conversion Rate then in effect, with such cash payment for fractional shares pursuant to Section 6(d). The Company may exercise its right to cause a mandatory conversion pursuant to this Section 8(a) only if the Closing Sale Price of the Common Stock equals or exceeds 300% of the then-prevailing Conversion Price for the 30 consecutive Trading Days prior to the Company’s issuance of a press release announcing the mandatory conversion as described in Section 8(b).

(b) To exercise the mandatory conversion right described in Section 8(a), the Company must issue a press release for publication on the Dow Jones News Service or Bloomberg Business News (or if either such service is not available, another broadly disseminated news or press release service selected by the Company) prior to the opening of business on the first Trading Day following any date on which the conditions described in Section 8(a) are met, announcing such a mandatory conversion. The Company shall also give notice by mail or by publication (with subsequent prompt notice by mail) to the holders of the Preferred Stock (not more than four Business Days after the date of the press release) of the mandatory conversion announcing the Company’s intention to convert the Preferred Stock. The conversion date will be a date selected by the Company (the “Mandatory Conversion Date”) and will be no more than 10 days after the date on which the Company issues the press release described in this Section 8(b).

(c) In addition to any information required by applicable law or regulation, the press release and notice of a mandatory conversion described in Section 8(b) shall state, as appropriate: (i) the Mandatory Conversion Date; (ii) the number of shares of Common Stock to be issued upon conversion of each share of Preferred Stock; and (iii) that dividends on the Preferred Stock to be converted will cease to accrue on the Mandatory Conversion Date.

(d) On and after the Mandatory Conversion Date, dividends shall cease to accrue on the Preferred Stock called for a mandatory conversion pursuant to Section 8(a) and all rights of holders of such Preferred Stock shall terminate except for the right to receive the whole shares of Common Stock issuable upon conversion thereof with such cash payment for fractional shares pursuant to Section 6(d).

(e) The Company may not authorize, issue a press release or give notice of any mandatory conversion pursuant to Section 8(a) unless there were no accumulated and unpaid dividends on the Preferred Stock as of the immediately preceding Dividend Payment Date.

9. Effect of Reclassification, Consolidation, Merger or Other Specified Transactions on Conversion Privilege.

(a) If any recapitalization, reclassification or change of the outstanding shares of Common Stock (other than a subdivision or combination to which Section 7(c) applies), consolidation, conversion, merger or combination involving the Corporation, sale, lease or other transfer to a third party of the consolidated assets of the Corporation and the Corporation’s subsidiaries substantially as an entirety, or any statutory share exchange, in each case as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets (including cash or any combination thereof) (any of the foregoing, a “Transaction”) shall occur then each share of Preferred Stock Outstanding immediately prior to such transaction shall be convertible into the kind and amount of shares of stock, other securities or other property or assets (including cash) receivable upon such Transaction by a holder of a number of shares of Common Stock issuable upon conversion of such Preferred Stock (assuming, for such purposes, a sufficient number of authorized shares of Common Stock are available to convert all such Preferred Stock) immediately prior to such Transaction after giving effect to any applicable adjustments (the “Reference Property”). If the holders of the Common Stock have the opportunity to elect the form of consideration to be received in the Transaction, the Reference Property into which the Preferred Stock will be convertible shall be deemed to be the weighted average of the types of consideration received by the holders of the Common Stock who affirmatively make such an election. The Corporation shall not become a party to any Transaction unless its terms are consistent with the foregoing.

(b) The above provisions of this Section 9 shall similarly apply to successive Transactions and the provisions of Section 7 shall apply with respect to any event or action after such Transaction that affects any shares of Capital Stock received by the holders of Common Stock in any such Transaction; provided that if this Section 9 applies to any Transaction, Section 7 shall not apply to such Transaction.

10. Rights Issued in Respect of Common Stock Issued Upon Conversion. Each share of Common Stock issued upon conversion of the Preferred Stock shall be entitled to receive the appropriate number of common stock or preferred stock purchase rights, as the case may be, including without limitation, the rights under the Rights Plan (collectively, the “Rights”), if any, that shares of Common Stock are entitled to receive and the certificates representing the Common Stock issued upon such conversion shall bear such legends, if any, in each case as may be provided by the terms of any shareholder rights agreement adopted by the Corporation, as the same may be amended from time to time (in each case, a “Rights Plan”). If such Rights Plan requires that each share of Common Stock issued upon conversion of the Preferred Stock at any time prior to the distribution of separate certificates representing the Rights be entitled to receive such Rights, then, notwithstanding anything else to the contrary in this Certificate, there shall not be any adjustment to the conversion privilege or Conversion Rate as a result of the issuance of Rights, but an adjustment to the Conversion Rate shall be made pursuant to Section 7(d) upon the separation of the Rights from the Common Stock, provided that no adjustment to the Conversion Rate shall be made pursuant to Section 7(d) upon such separation if (a) at the time of separation the Corporation sets aside for issuance upon conversion of the Preferred Stock a number of rights equal to the rights the holders of Preferred Stock would have received if the conversion occurred immediately prior such separation and (b) the rights so set aside are perpetual in duration.

11. Voting Rights.

(a) The holders of record of shares of the Preferred Stock shall not be entitled to any voting rights except as hereinafter provided in this Section 11 or as otherwise provided by law. Each share of Preferred Stock held by any member of an Investor Group shall entitle the holder thereof to the number of votes equal to the Adjusted Voting Number applicable to shares of Preferred Stock held by members of such Investor Group. Furthermore, holders of Preferred Stock shall otherwise have voting rights and powers equal to the voting rights and powers of the Common Stock (except as otherwise expressly provided herein or as required by law, voting together with the Common Stock as a single class) and shall be entitled to notice of any stockholders’ meeting in accordance with the Bylaws of the Corporation. Fractional votes shall not, however, be permitted and any fractional voting rights resulting from the above formula (after aggregating all shares into which shares of Preferred Stock held by each holder could be converted) shall be rounded to the nearest whole number (with one-half being rounded upward).

(b) The affirmative vote of holders of a majority of the Outstanding shares of the Preferred Stock, voting as a single class, in person or by proxy, at an annual meeting of the Corporation’s stockholders or at a special meeting called for the purpose, or by written consent in lieu of such a meeting, shall be required to (i) approve the issuance of any Senior Stock subsequent to the Original Issue Date for the Preferred Stock; (ii) approve a merger, conversion, statutory share exchange, sale of substantially all the assets or liquidation of the Corporation, in each case, occurring prior to the third anniversary of the Original Issue Date; (iii) alter, repeal or amend, whether by merger, consolidation, combination, reclassification or otherwise, any provisions of this Certificate; or (iv) alter, repeal or amend, whether by merger, consolidation, combination, reclassification, or otherwise, any provision of the Amended and Restated Certificate of Incorporation (other than this Certificate), if such action would amend, alter or affect the powers, preferences or special rights of the Preferred Stock, so as to adversely affect the holders thereof, including, without limitation, the creation of, or increase in the authorized number of, shares of any class or series of Senior Stock; provided, however, that any increase in the amount of the authorized Common Stock or authorized preferred stock (but excluding any increase in the authorized Preferred Stock) or the creation and issuance of any class or series of Common Stock, other Junior Stock or Parity Stock will not be deemed to adversely affect such powers, preferences or special rights.

(c) Notwithstanding any provision hereof to the contrary, each holder of record of Preferred Stock shall not be entitled to cast any vote together with the holders of record of Common Stock, unless such holder of Preferred Stock provides a written certification to the Corporation specifying the total number of issued and outstanding shares of Common Stock and the total number of issued and Outstanding shares of Preferred Stock Beneficially Owned by the Investor Group of which such holder is a member.

12. Transfer Agent and Registrar. The duly appointed Transfer Agent (the “Transfer Agent”) or Registrar (the “Registrar”) for the Preferred Stock shall be American Stock Transfer & Trust Company. The Corporation may, in its sole discretion, remove the Transfer Agent and Registrar in accordance with the agreement between the Corporation and the Transfer Agent and Registrar; provided that the Corporation shall appoint a successor transfer agent and registrar who shall accept such appointment prior to the effectiveness of such removal.

13. Currency. All shares of Preferred Stock shall be denominated in U.S. currency, and all payments and distributions thereon or with respect thereto shall be made in U.S. currency. All references herein to “$”or “dollars” refer to U.S. currency.

14. Form.

(a) The Preferred Stock shall be issued in the form of one or more permanent global shares of Preferred Stock (each, a “Global Preferred Share”) in definitive, fully registered form with the global legend (the “Global Shares Legend”) each as set forth on the form of Preferred Stock certificate attached hereto as Exhibit A, which is hereby incorporated in and expressly made a part of this Certificate. The Global Preferred Shares may have notations, legends or endorsements required by law, stock exchange rules, agreements to which the Corporation is subject, if any, or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Corporation). The Global Preferred Shares shall be deposited on behalf of the holders of the Preferred Stock represented thereby with the Registrar, at its New York office, as custodian for the Depositary, and registered in the name of the Depositary or a nominee of the Depositary, duly executed by the Corporation and countersigned and registered by the Registrar as hereinafter provided. The aggregate number of shares represented by each Global Preferred Share may from time to time be increased or decreased by adjustments made on the records of the Registrar and the Depositary or its nominee as hereinafter provided. This Section 14 shall apply only to a Global Preferred Share deposited with or on behalf of the Depositary. The Corporation shall execute and the Registrar shall, in accordance with this Section 14, countersign and deliver initially one or more Global Preferred Shares that (i) shall be registered in the name of Cede & Co. or other nominee of the Depositary and (ii) shall be delivered by the Registrar to Cede & Co. or pursuant to instructions received from Cede & Co. or held by the Registrar as custodian for the Depositary pursuant to an agreement between the Depositary and the Registrar. Members of, or participants in, the Depositary (“Agent Members”) shall have no rights under this Certificate, with respect to any Global Preferred Share held on their behalf by the Depositary or by the Registrar as the custodian of the Depositary, or under such Global Preferred Share, and the Depositary may be treated by the Corporation, the Registrar and any agent of the Corporation or the Registrar as the absolute owner of such Global Preferred Share for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Corporation, the Registrar or any agent of the Corporation or the Registrar from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Agent Members, the operation of customary practices of the Depositary governing the exercise of the rights of a holder of a beneficial interest in any Global Preferred Share. Owners of beneficial interests in Global Preferred Shares shall not be entitled to receive physical delivery of certificated shares of Preferred Stock, unless (x) DTC is unwilling or unable to continue as Depositary for the Global Preferred Shares and the Corporation does not appoint a qualified replacement for DTC within 90 days, (y) DTC ceases to be a “clearing agency” registered under the Exchange Act or (z) the Corporation decides to discontinue the use of book-entry transfer through DTC (or any successor Depositary). In any such case, the Global Preferred Shares shall be exchanged in whole for certificated shares of Preferred Stock in registered form, with the same terms and of an equal aggregate Adjusted Liquidation Preference (unless the Corporation determines otherwise in accordance with applicable law). Certificated shares of Preferred Stock shall be registered in the name or names of the Person or Person specified by DTC in a written instrument to the Registrar.

(b)

(i) Officers shall sign the Global Preferred Shares for the Corporation, in accordance with the Corporation’s bylaws and applicable law, by manual or facsimile signature.

(ii) If the Officers whose signatures are on a Global Preferred Share no longer hold that office at the time the Transfer Agent authenticates the Global Preferred Share, the Global Preferred Share shall be valid nevertheless.

(iii) A Global Preferred Share shall not be valid until an authorized signatory of the Transfer Agent manually countersigns such Global Preferred Share. The signature shall be conclusive evidence that such Global Preferred Share has been authenticated under this Certificate. Each Global Preferred Share shall be dated the date of its authentication.

15. Registration; Transfer.

(a) Notwithstanding any provision to the contrary herein, so long as a Global Preferred Share remains Outstanding and is held by or on behalf of the Depositary, transfers of a Global Preferred Share, in whole or in part, or of any beneficial interest therein, shall only be made in accordance with this Section 15.

(b) Transfers of a Global Preferred Share shall be limited to transfers of such Global Preferred Share in whole, but not in part, to nominees of the Depositary or to a successor of the Depositary or such successor’s nominee.

16. Paying Agent and Conversion Agent.

(a) The Corporation shall maintain in the Borough of Manhattan, City of New York, State of New York (i) an office or agency where Preferred Stock may be presented for payment (the “Paying Agent”) and (ii) an office or agency where Preferred Stock may be presented for conversion (the “Conversion Agent”). The Transfer Agent shall act as Paying Agent and Conversion Agent, unless another Paying Agent or Conversion Agent is appointed by the Corporation. The Corporation may appoint the Registrar, the Paying Agent and the Conversion Agent and may appoint one or more additional paying agents and one or more additional conversion agents in such other locations as it shall determine. The term “Paying Agent” includes any additional paying agent and the term “Conversion Agent” includes any additional conversion agent. The Corporation may change any Paying Agent or Conversion Agent without prior notice to any holder. The Corporation shall notify the Registrar of the name and address of any Paying Agent or Conversion Agent appointed by the Corporation. If the Corporation fails to appoint or maintain another entity as Paying Agent or Conversion Agent, the Registrar shall act as such. The Corporation or any of its Affiliates may act as Paying Agent, Registrar or Conversion Agent. The Registrar shall record any exchanges, increases or decreases in the number of shares of Preferred Stock represented by a Global Preferred Share on Schedule A to such Global Preferred Share.

(b) Payments due on the Preferred Stock shall be payable at the office of the Paying Agent in The City of New York and at any other office or agency maintained by the Corporation for such purpose. Payments shall be payable by United States dollar check drawn on, or wire transfer (provided, that appropriate wire instructions have been received by the Registrar at least 15 days prior to the applicable date of payment) to a U.S. dollar account maintained by the holder with, a bank located in New York City; provided that at the option of the Corporation, payment of dividends may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Preferred Stock register. Notwithstanding the foregoing, payments due in respect of beneficial interests in the Global Preferred Shares shall be payable by wire transfer of immediately available funds in accordance with the procedures of the Depositary.

Section 3. Registration Rights.

(a) Shelf Registration Statement. The Company shall (i) file with the SEC a shelf registration statement on Form S-1 (or, if the Company is eligible to use such form, Form S-3) relating to the registration of the offer and resale by the Holders of all of the Registrable Securities (the “Shelf Registration Statement”) and (ii) use its commercially reasonable efforts to cause the Shelf Registration Statement to be declared effective by the SEC no later than the date that is one (1) year after the date hereof; provided, however, that the Company shall not be obligated to effect any such registration pursuant to this Section 3(a), or keep such registration or the Shelf Registration Statement effective pursuant to Section 3(d)(i), during any Blackout Period.

(b) Piggyback Registration Rights.

(i) Piggyback Registration. If after the date that is one (1) year after the date hereof, the Company shall determine to (A) file a registration statement to register the offer and sale for cash of any of its Common Stock for its own account in an underwritten offering, other than (i) a registration relating solely to employee benefit plans or securities issued or issuable to employees, directors or consultants (to the extent the securities owned or to be owned by such consultants could be registered on Form S-8) or any of their Family Members (including a registration on Form S-8), (ii) a registration on Form S-4 in connection with a merger, acquisition, divestiture, reorganization, exchange offer or similar event, (iii) a registration in which the only Common Stock being registered is Common Stock issuable upon conversion of debt securities that are also being registered or (iv) a shelf registration statement on Form S-3 or (B) file a prospectus supplement to an effective shelf registration statement with respect to an underwritten public offering in which Holders may be included (either by inclusion in the registration statement without the filing of a post-effective amendment thereto or because the Shelf Registration Statement is effective) (an offering pursuant to clause (A) or (B), a “Piggyback Offering”), then the Company shall promptly give to the Holders written notice thereof, and in no event shall such notice be given less than (X) twenty (20) calendar days prior to the filing of a registration statement contemplated by clause (A) (a “Piggyback Registration Statement”) or (Y) five (5) calendar days prior to the filing of a prospectus supplement contemplated by clause (B) ( a “Piggyback Supplement”) and the Company shall, subject to Section 3(b)(ii), include in such Piggyback Offering all of the Registrable Securities specified in a written request or requests, made within ten (10) calendar days (three (3) calendar days in the case of a Piggyback Supplement) after receipt of such written notice from the Company, by any Holder or Holders. However, the Company may, without the consent of the Holders, abandon such Piggyback Offering and withdraw such Piggyback Registration Statement or Piggyback Supplement.

(ii) Underwriting Procedures. The right of any Holder to be included in a Piggyback Offering pursuant to Section 3(b)(i) shall be conditioned upon such Holder’s participation in, and the inclusion of such Holder’s Registrable Securities in, the underwriting arrangements with respect to such Piggyback Offering to the extent provided herein. All Holders proposing to sell their securities through such Piggyback Offering shall (together with the Company) enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such Piggyback Offering by the Company. No Holder may participate in such Piggyback Offering unless such Holder agrees to sell its Registrable Securities on the basis provided in such underwriting agreement and completes and executes all questionnaires, powers of attorney, indemnities and other documents reasonably required under the terms of such underwriting agreement. Each Holder may, at its option, require that any or all of the representations and warranties by, and the other agreements on the part of, the Company to and for the benefit of the underwriters also be made to and for such Holder’s benefit and that any or all of the conditions precedent to the obligations of the underwriters under such underwriting agreement also be conditions precedent to such Holder’s obligations. No Holder shall be required to make any representations or warranties to or agreements with the Company or the underwriters other than representations, warranties or agreements regarding such Holder and its ownership of the securities being registered on its behalf, its intended method of distribution and any other representation required by law, and no Holder shall be required to agree to indemnify any person beyond the scope of the indemnification provided to the Company under Section 3(h). Notwithstanding any other provision of this Section 3(b)(ii), if the managing underwriter or the Company determines that marketing factors require a limitation of the number of shares to be underwritten, the underwriters may exclude from such Piggyback Offering the number of shares in excess of such limitation. The Company shall so advise all Holders (except those Holders who failed to timely elect to sell their Registrable Securities through such Piggyback Offering or have indicated to the Company their decision not to do so), and the number of shares that may be included in the underwriting shall be allocated:

(A) first, to the Company;

(B) second, to the Holders who have requested to sell their Registrable Securities in the Piggyback Offering and all other selling stockholders who have rights of registration on parity with the Holders and have requested to sell securities in the Piggyback Offering, on a pro rata basis according to the number of shares requested to be included; and

(C) then, to any other selling stockholders who have registration rights and have requested to sell securities in the Piggyback Offering.

No Registrable Securities excluded from the underwriting by reason of the underwriters’ marketing limitation shall be included in the Piggyback Offering. If any Holder disapproves of the terms of the underwriting arrangements with respect to a Piggyback Offering, such Holder may elect to withdraw therefrom by written notice to the Company and the managing underwriter; provided, however, that such withdrawal must be made at a time prior to the time of the pricing of the Piggyback Offering. The Registrable Securities and/or other securities so withdrawn from such underwriting shall also be withdrawn from such Piggyback Offering; provided, however, that, if by the withdrawal of such Registrable Securities a greater number of Registrable Securities held by other Holders may be included in such Piggyback Offering (up to the maximum of any limitation imposed by the underwriters), then the Company shall offer to all Holders who have included Registrable Securities in the Piggyback Offering the right to include additional Registrable Securities pursuant to the terms and limitations set forth herein in the same proportions described above.

(i) In the event that one or more Holders elects to sell $25 million or more of Registrable Securities under the Shelf Registration Statement, the Company shall, upon request by such Holders, retain underwriters in order to permit such Holders to effect such offering. The obligation of the Company to retain underwriters shall include entering into an underwriting agreement in customary form with the underwriters or initial purchasers, which shall include, among other provisions, indemnities to the effect and to the extent provided in Section 3(h) and taking all reasonable actions as are requested by the underwriters or initial purchaser to expedite or facilitate the disposition of such Registrable Securities. The Company shall, upon request of the Holders, cause its management to participate in a roadshow or similar marketing effort on behalf of the Holders.

(ii) In no event shall the Company be required to participate in more than two underwritten offerings in any 12-month period.

(iii) In connection with any underwritten offering pursuant to this Section 3(c), (A) Holders holding a majority of the Registrable Securities being sold in such underwritten offering shall be entitled to select the managing underwriter or initial purchaser, subject to the approval of the Company, which approval shall not be unreasonably withheld and (B) each Holder participating in the underwritten offering and the Company shall be obligated to enter into an underwriting agreement in customary form. No Holder may participate in such underwritten offering unless such Holder agrees to sell its Registrable Securities on the basis provided in such underwriting agreement and completes and executes all questionnaires, powers of attorney, indemnities and other documents reasonably required under the terms of such underwriting agreement. Each Holder may, at its option, require that any or all of the representations and warranties by, and the other agreements on the part of, the Company to and for the benefit of the underwriters also be made to and for such Holder’s benefit and that any or all of the conditions precedent to the obligations of the underwriters under such underwriting agreement also be conditions precedent to such Holder’s obligations. No Holder shall be required to make any representations or warranties to or agreements with the Company or the underwriters other than representations, warranties or agreements regarding such Holder and its ownership of the securities being registered on its behalf, its intended method of distribution and any other representation required by law, and no Holder shall be required to agree to indemnify any person beyond the scope of the indemnification provided to the Company under Section 3(h). If any Holder disapproves of the terms of the underwriting arrangements with respect to such underwritten offering, such Holder may elect to withdraw therefrom by written notice to the Company and the underwriter; provided, however, that such withdrawal must be made at a time prior to the time of pricing of such underwritten offering. Neither the Company nor any selling stockholders who have registration rights shall have any right to include securities in an underwritten offering by the Holders pursuant to this Section 3(c) and the Company shall not purport to grant any current or future shareholder such right.

(d) Registration Procedures. In the case of each registration, offering, qualification, or compliance effected by the Company pursuant to Section 3(a), Section 3(b) or Section 3(c), the Company will keep each Holder including securities therein reasonably advised in writing (which may include e-mail) as to the initiation of each registration, offering, qualification, and compliance and as to the completion thereof. In addition, the Company hereby agrees as follows:

(i) The Company will use its commercially reasonable efforts to cause the Shelf Registration Statement to become and remain effective at least for a period ending with the first to occur of (A) the sale by the Holders of all Registrable Securities covered by such Registration Statement, (B) the sale of such Registrable Securities under Rule 144, or (C) the date that is three years after the SEC Effective Date of the Shelf Registration Statement; provided, however, that if the Company files the Shelf Registration Statement on Form S-1, subsequently becomes eligible to use Form S-3, and files a post-effective amendment to such Form S-1 on Form S-3 prior to the end of such period, the Company will use its commercially reasonable efforts to cause such Shelf Registration Statement as amended to remain effective until the end of such period (in any such case, the “Effectiveness Period”). At any time after the end of the Effectiveness Period with respect to the Shelf Registration Statement, if (a) the Holders Beneficially Own Registrable Securities representing more than 5% of the fully diluted equity interests in the Company (calculated giving effect to the exercise of all outstanding options, warrants and other rights to purchase or acquire any Common Stock of the Company) or (b) any Investor Director (as defined in the Investment Agreement) is a member of the Board, then (w) as promptly as reasonably practicable after the written request of Holders of a majority of the Registrable Securities, the Company shall file with the SEC another shelf registration statement on Form S-1 (or, if the Company is eligible to use such form, Form S-3) relating to the registration of the offer and resale by the Holders of all of the Registrable Securities, (x) the provisions of this Agreement (including without limitation the provisions of Section 3(a) and Section 3(d)) shall apply to such registration statement, (y) such registration statement shall be deemed to be the Shelf Registration Statement (as defined in Section 3(a)) for purposes of this Agreement and (z) the Effectiveness Period shall resume upon effectiveness of any such shelf registration statement for the period specified in the first sentence of this Section 3(d)(i).

(ii) If any Registration Statement becomes subject to review by the SEC, the Company will promptly respond to all comments and diligently pursue resolution of any comments to the satisfaction of the SEC.

(iii) The Company (A) will prepare and file with the SEC such amendments and supplements to each Shelf Registration Statement and any prospectus used in connection therewith as may be reasonably necessary to keep such Shelf Registration Statement effective during the applicable Effectiveness Period, (B) will comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such Shelf Registration Statement during such period in accordance with the intended method(s) of disposition by the sellers thereof set forth in such Shelf Registration Statement and (C), if advised in writing by the managing underwriter of an underwritten offering that, in the judgment of such underwriter, inclusion of detailed information regarding the Company in the prospectus or prospectus supplement is of material importance to the success of such offering, will use its commercially reasonable efforts to include such information in such prospectus or prospectus supplement.

(iv) The Company will furnish, without charge, to each Holder (A) a reasonable number of copies of each Registration Statement (including any exhibits thereto other than exhibits incorporated by reference), each amendment and supplement thereto as such Holder may request, (B) such number of copies of the prospectus included in such Registration Statement (including each preliminary prospectus and any other prospectus filed under Rule 424 under the Securities Act) as each Holder may request, in conformity with the requirements of the Securities Act, and (C) such other documents as each Holder may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such Holder, but only during the applicable Effectiveness Period.

(v) The Company will use its commercially reasonable efforts to register or qualify the Registrable Securities under the applicable securities or blue sky laws of such jurisdictions as the Holders of a majority of the Registrable Securities reasonably requests as may be necessary for the marketability of the Registrable Securities (such request to be made by the time the relevant Registration Statement is deemed effective by the SEC) and do any and all other acts and things which may be reasonably necessary or advisable to enable the Holders to consummate the disposition in such jurisdictions of the Registrable Securities owned by the Holders; provided, however, that the Company shall not be required to (A) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this paragraph (v), (B) subject itself to taxation in any such jurisdiction, or (C) consent to general service of process in any such jurisdiction.

(vi) As promptly as practicable after becoming aware of such event, the Company will notify each Holder of Registrable Securities being offered or sold pursuant to each Registration Statement at any time when a prospectus relating thereto is required to be delivered under the Securities Act of the happening of any event which comes to the Company’s attention if as a result of such event the prospectus included in such Registration Statement contains an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and the Company shall promptly prepare and furnish to such Holder a supplement or amendment to such prospectus (or prepare and file appropriate reports under the Exchange Act) so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus shall not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, unless suspension of the use of such prospectus otherwise is authorized herein or in the event of a Blackout Period, in which case no supplement or amendment need be furnished (or Exchange Act filing made) until the termination of such suspension or Blackout Period.

(vii) The Company will comply, and continue to comply during the period that each Registration Statement is effective under the Securities Act, in all material respects with the Securities Act and the Exchange Act and with all applicable rules and regulations of the SEC with respect to the disposition of all securities covered by such Registration Statement.

(ix) The Company will permit the Holders of Registrable Securities being offered or sold pursuant to each Registration Statement and their legal counsel, at such Holders’ sole cost and expense, to review and have a reasonable opportunity to comment on such Registration Statement and all amendments and supplements thereto (unless such Registration Statement, amendments and supplements are filed without inclusion of any Registrable Securities therein) at least two (2) Business Days prior to their filing with the SEC, and will make any corrections reasonably requested by any such Holder with respect to information pertaining to such Holder and its plan of distribution prior to such filing.

(x) The Company will make available for inspection by the Holders and any Inspector retained by the Holders, at the Holders’ sole expense, all records as shall be reasonably necessary to enable the Holders and any underwriters to exercise their due diligence responsibility, and cause the Company’s officers, directors, and employees to supply all information which the Holders, any Inspector or any underwriter may reasonably request for purposes of such due diligence; provided, however, that the Holders shall hold in confidence and shall not make any disclosure of any information which the Company determines in good faith to be confidential, and of which determination the Holders are so notified at the time the Holders receive such information, unless (A) the Holders have, or obtained, knowledge of such information without violation of or protection under any agreements with the Company or, to its knowledge any third party, (B) the disclosure of such information is reasonably necessary to avoid or correct a misstatement or omission in each Registration Statement and a reasonable time prior to such disclosure the Holders shall have informed the Company of the need to so correct such misstatement or omission and the Company shall have failed to correct such misstatement of omission, (C) the release of such information is ordered pursuant to a subpoena or other order from a court or governmental body of competent jurisdiction or (D) the information has been made generally available to the public other than by disclosure in violation of this Agreement or any other agreement. The Company shall not be required to disclose any confidential information to any Holder, Inspector or underwriter until and unless such Holder, Inspector or underwriter shall have entered into a confidentiality agreement with the Company with respect thereto, containing terms substantially similar to those set forth in this Section 3(d)(x), which agreement shall permit an Inspector retained by any Holder to disclose information to such Holder. Each Holder agrees that it shall, upon learning that disclosure of such information is sought in or by a court or governmental body of competent jurisdiction or through other means, give prompt notice to the Company and allow the Company, at the Company’s expense, to undertake appropriate action to prevent disclosure of, or to obtain a protective order for, the information deemed confidential. The Company shall hold in confidence and shall not make any disclosure of information concerning the Holders provided to the Company pursuant to this Agreement unless (1) disclosure of such information is reasonably necessary to comply with federal or state securities laws, (2) disclosure of such information to the SEC’s Staff of the Division of Corporation Finance is reasonably necessary to respond to comments raised by such staff in its review of such Registration Statement, (3) disclosure of such information is reasonably necessary to avoid or correct a misstatement or omission in such Registration Statement, (4) release of such information is ordered pursuant to a subpoena or other order from a court or governmental body of competent jurisdiction, or (5) such information has been made generally available to the public other than by disclosure in violation of this or any other agreement.

(xi) The Company will use its commercially reasonable efforts to cause all the Registrable Securities covered by each Registration Statement to be listed or quoted on the principal securities market on which securities of the same class or series issued by the Company are then listed or traded.

(xii) The Company will provide a transfer agent and registrar, which may be a single entity, for the Registrable Securities at all times.

(xiii) The Company will cooperate with the Holders of Registrable Securities being offered pursuant to each Registration Statement to facilitate the timely preparation and delivery of certificates (not bearing any restrictive legends) representing Registrable Securities to be offered pursuant to such Registration Statement and enable such certificates to be in such denominations or amounts as the Holders may reasonably request.

(xiv) The Company will take all other reasonable actions necessary to expedite and facilitate disposition by the Holders of the Registrable Securities pursuant to each Registration Statement, including without limitation making its chief executive officer, president, chief financial officer and other appropriate officers and personnel available to participate in marketing efforts with respect to any registered underwritten public offering.

(xv) In the case of an underwritten offering, the Company shall furnish to the participating Holders signed counterparts, addressed to such Holders, of (i) any opinion of counsel to the Company delivered to any underwriter and (ii) any comfort letter from the Company’s independent public accountants (or accountants for any entity acquired by the Company whose financial statements are included in a Registration Statement) delivered to any underwriter. In the event no legal opinion is delivered to any underwriter, or in non-underwritten transactions, the Company shall furnish to participating Holders, at any time that such Holders elect to use a prospectus, an opinion of counsel to the Company stating only that the Registration Statement containing such prospectus has been declared effective and that no stop order is in effect.

(xvi) The Company shall comply with all applicable rules and regulations of the SEC and the Securities Act, and also make available to its stockholders, as soon as practicable, an earnings statement covering a period of twelve (12) months, beginning within three (3) months after the effective date of the Registration Statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder.

(e) Suspension of Offers and Sales. Each Holder of Registrable Securities agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 3(d)(vi) or of the commencement of a Blackout Period, such Holder shall discontinue and suspend disposition of Registrable Securities pursuant to any Registration Statement until the Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by Section 3(d)(vi) or notice of the end of the Blackout Period, and, if so directed by the Company, such Holder shall deliver to the Company (at the Company’s expense) all copies (including, without limitation, any and all drafts), other than permanent file copies, then in such Holder’s possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice.

(f) Registration Expenses. All expenses incident to the Company’s performance of or compliance with this Agreement, including without limitation all registration and filing fees, messenger and delivery expenses, printing expenses, internal expenses (including without limitation all salaries and expenses of its officers and employees performing legal or accounting duties), all fees and expenses associated with filings required to be made with FINRA, as may be required by the rules and regulations of FINRA, fees and expenses of compliance with securities or blue sky laws (including reasonable fees and disbursements of counsel in connection with blue sky qualifications of the Registrable Securities), rating agency fees, the fees and expenses incurred in connection with the listing of the securities to be registered on all securities exchanges on which similar securities issued by the Company are then quoted or listed, fees and disbursements of counsel for the Company and its independent certified public accountants, and the fees and expenses of any other persons retained by the Company, in connection with the registration hereunder (collectively, the “Registration Expenses”) will be borne by the Company, but not including any roadshow expenses of the Holders, fees and expenses of counsel for the Holders and any underwriting, broker or dealer discounts or commissions attributable to the sale of Registrable Securities (which are hereinafter referred to as “Selling Expenses”).

(g) Information by the Holder. The Holder or Holders of Registrable Securities included in any Registration Statement shall furnish to the Company such information required under Regulation S-K under the Securities Act regarding such Holder or Holders and the distribution proposed by such Holder or Holders as the Company may request in writing. No Holder of Registrable Securities will be entitled to have such Registrable Securities included in a Registration Statement if such Holder does not furnish such information requested by the Company.

(h) Indemnification.

(i) In the event of the offer and sale of Registrable Securities under the Securities Act, the Company shall, and hereby does, indemnify and hold harmless, to the fullest extent permitted by law, each Holder, its directors, officers, employees, agents, and partners, each other person who participates as an underwriter in the offering or sale of such securities, and each other person, if any, who controls or is under common control with such Holder or any such underwriter within the meaning of Section 15 of the Securities Act, against any losses, claims, damages, liabilities (joint or several), and expenses to which such Holder or any such director, officer, employee, agent or partner, underwriter or controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages, liabilities or expenses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in (A) any Registration Statement, any preliminary prospectus, final prospectus, summary prospectus or free writing prospectus, or any amendment or supplement thereto, or (B) in any materials or information provided to investors by, or with the written approval of, the Company in connection with the marketing of the offering of the Registrable Securities (“Marketing Materials”), including any road show or investor presentations made to investors by the Company (whether in person or electronically), or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus or free writing prospectus, in light of the circumstances in which they were made) not misleading, and the Company shall reimburse the Holder, and each such director, officer, employee, agent, partner, underwriter and controlling person for any legal or any other expenses reasonably incurred by them in connection with investigating, defending or settling any such loss, claim, damage, liability, action or proceeding; provided that the foregoing shall not apply, and the Company shall not be liable, in any such case to the extent that any such loss, claim, damage, liability (or action or proceeding, whether commenced or threatened, in respect thereof) or expense arises out of or is based upon (X) an untrue statement or alleged untrue statement in or omission or alleged omission from such Registration Statement, any such preliminary prospectus, final prospectus, summary prospectus or free writing prospectus, or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Company through an instrument duly executed by or on behalf of such Holder specifically stating that it is for use in the preparation thereof, or (Y) such Holder’s failure to comply with the terms of the plan of distribution mechanics described in the applicable prospectus. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Holders, or any such director, officer, employee, agent, partner, underwriter or controlling person, and shall survive the transfer of such shares by the Holders.

(ii) As a condition to including any Registrable Securities to be offered by a Holder in any Registration Statement, such Holder agrees to be bound by the terms of this Section 3(h) and to indemnify and hold harmless, to the fullest extent permitted by law, the Company, its directors, officers, employees and agents, each other person, if any, who controls the Company within the meaning of Section 15 of the Securities Act, legal counsel and accountants for the Company, any underwriter, any other Holder selling securities in such Registration Statement (or any other registration statement filed by the Company to which a Piggyback Supplement relates) and any controlling person within the meaning of the Securities Act of any such underwriter or other Holder, against any losses, claims, damages, liabilities (joint or several), and expenses to which the Company, any of its directors, officer, employees, agents, controlling persons, legal counsel or accountants, any underwriter, any other Holder, or any controlling person of such underwriter or other Holder may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages, liabilities (or actions or proceedings, whether commenced or threatened, in respect thereof) or expenses arise out of or are based upon (A) an untrue statement or alleged untrue statement in or omission or alleged omission from any Registration Statement (or any other registration statement filed by the Company to which a Piggyback Supplement relates), any preliminary prospectus, final prospectus, summary prospectus or free writing prospectus, or any amendment or supplement thereto, if such statement or alleged statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company through an instrument duly executed by or on behalf of such Holder specifically stating that it is for use in the preparation thereof, or (B) such Holder’s failure to comply with the terms of the plan of distribution mechanics described in the applicable prospectus. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Company, any such director, officer, employee, agent or controlling person, any such underwriter or other Holder, or any controlling person of any such underwriter or other Holder, and shall survive the transfer of such shares by the Holder, and such Holder shall reimburse the Company, any of its directors, officer, employees, agents, controlling persons, legal counsel or accountants, any underwriter, any other Holder, or any controlling person of such underwriter or other Holder for any legal or other expenses reasonably incurred by them in connection with investigating, defending, or settling such loss, claim, damage, liability, action, or proceeding; provided, however, that such indemnity agreement found in this Section 3(h)(ii) shall in no event exceed the gross proceeds from the offering received by such Holder.

(iii) Promptly after receipt by an indemnified party of notice of the commencement of any action or proceeding involving a claim referred to in Section 3(h)(i) or Section 3(h)(ii) (including any governmental action), such indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party, give written notice to the indemnifying party of the commencement of such action; provided, however, that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations under Section 3(h)(i) or Section 3(h)(ii), except to the extent that the indemnifying party is actually prejudiced by such failure to give notice. If any such action is brought against an indemnified party, unless in the reasonable judgment of counsel to such indemnified party a conflict of interest between such indemnified and indemnifying parties may exist (including situations in which the indemnified party may have defenses not available to the indemnifying party) in respect of such claim, the indemnifying party shall be entitled to participate in and to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party for any legal or other expenses subsequently incurred by the latter in connection with the defense thereof, unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties arises in respect of such claim after the assumption of the defenses thereof or the indemnifying party fails to defend such claim in a diligent manner, other than reasonable costs of investigation. Neither an indemnified nor an indemnifying party shall be liable for any settlement of any action or proceeding effected without its consent. No indemnifying party shall, without the consent of the indemnified party, consent to entry of any judgment or enter into any settlement, which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect of such claim or litigation. Notwithstanding anything to the contrary set forth herein, and without limiting any of the rights set forth above, in any event any party shall have the right to retain, at its own expense, counsel with respect to the defense of a claim.

(iv) In the event that an indemnifying party does or is not permitted to assume the defense of an action pursuant to Section 3(h)(iii) or in the case of the expense reimbursement obligation set forth in Section 3(h)(i) and Section 3(h)(ii), the indemnification required by Section 3(h)(i) and Section 3(h)(ii) shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills received or expenses, losses, damages, or liabilities are incurred.

(v) If the indemnification provided for in this Section 3(h) is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any loss, liability, claim, damage or expense referred to herein, the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall (A) contribute to the amount paid or payable by such indemnified party as a result of such loss, liability, claim, damage or expense as is appropriate to reflect the proportionate relative fault of the indemnifying party on the one hand and the indemnified party on the other (determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission relates to information supplied by the indemnifying party or the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission), or (B) if the allocation provided by clause (A) above is not permitted by applicable law or provides a lesser sum to the indemnified party than the amount hereinafter calculated, not only the proportionate relative fault of the indemnifying party and the indemnified party, but also the relative benefits received by the indemnifying party on the one hand and the indemnified party on the other, as well as any other relevant equitable considerations; provided, however, that in no event shall any Holder be required to contribute an aggregate amount in excess of the gross proceeds from the offering received by such Holder. No indemnified party guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any indemnifying party who was not guilty of such fraudulent misrepresentation.

(vi) Indemnification similar to that specified in the preceding subsections of this Section 3(h) (with appropriate modifications) shall be given by the Company and each Holder of Registrable Securities with respect to any required registration or other qualification of securities under any federal or state law or regulation or governmental authority other than the Securities Act.

Section 4. Miscellaneous.

(a) Assignment of Rights; Successors and Permitted Assignees. No Holder may assign its rights under this Agreement to any party without the prior written consent of the Company; provided, however, that a Holder may assign its rights under this Agreement without such restrictions to a Permitted Assignee as long as (i) such transfer or assignment is effected in accordance with applicable securities laws; (ii) such transferee or assignee agrees in writing to become subject to the terms of this Agreement as a Holder; and (iii) the Company is given written notice by such Holder of such transfer or assignment, stating the name and address of the transferee or assignee and identifying the Registrable Securities with respect to which such rights are being transferred or assigned.
