The Exercise Price is subject to adjustment as provided herein, and all references to “Exercise Price” herein shall be deemed to include any such adjustment or series of adjustments.

(b) Notwithstanding any other provision of this Warrant, and subject to Section 2(c), if the Warrantholder proposes to exercise this Warrant such that the Warrantholder (or the applicable Series A Regulatory Group), together with any other Person whose Company securities would be aggregated with such Warrantholder’s Company securities (including the applicable Series A Regulatory Group’s Company securities) for purposes of any bank regulation or law, would collectively be deemed to own, control or have the power to vote more than 9.9% of a class of the Company’s outstanding voting securities immediately following such exercise, calculated in accordance with the regulations of the Board of Governors of the Federal Reserve System at 12 C.F.R. § 225.9(a), and further excluding for the purpose of this calculation any reduction in ownership resulting from transfers by such Warrantholder (and any other member of the applicable Series A Regulatory Group) of voting securities of the Company, then the Warrantholder shall instead acquire shares of Common Stock such that the Warrantholder (or the applicable Series A Regulatory Group), together with any other Person whose Company securities would be aggregated with such Warrantholder’s Company securities (including the applicable Series A Regulatory Group’s Company securities) for purposes of any bank regulation or law, would collectively be deemed to own, control or have the power to vote 9.9% or less of any class of the Company’s outstanding voting securities immediately following such exercise; provided, that some or all of any shares in excess of such amount, at the election of the Warrantholder, shall be (i) issued as either Series B Preferred Stock or Non-Voting Common Stock, or (ii) provided for future issuance under the terms of this Warrant, as amended, with the exercise of the Warrant remaining subject to the limitation prohibiting the acquisition of more than 9.9% of any class of the Company’s outstanding voting securities set forth in the preceding clause; provided, further, that the Company shall cooperate with the Warrantholder (and any other member of the applicable Series A Regulatory Group) to effectuate the issuance of such Series B Preferred Stock or Non-Voting Common Stock, or the amendment of this Warrant; and, provided, further, that all of the representations, warranties, covenants, agreements and other provisions in this Warrant shall apply, mutatis mutandis, to any such Series B Preferred Stock, Non-Voting Common Stock, or under this Warrant following amendment hereunder.

(c) Notwithstanding any other provision of this Warrant, if the Warrantholder proposes to exercise this Warrant such that a Series A Regulatory Group would immediately thereafter directly or indirectly own or control greater than one-third of the total equity of the Company, calculated in accordance with the regulations of the Board of Governors of the Federal Reserve System at 12 C.F.R. § 225.34, then the Warrantholder shall instead only be permitted to exercise this Warrant to the extent that the shares of Common Stock issued hereunder would not cause the Series A Regulatory Group to own or control greater than one-third of the total equity of the Company, and all shares in excess of such amount shall be provided for future issuance under the terms of this Warrant, as amended, with the exercise of the Warrant remaining subject to the limitation prohibiting the acquisition of more than one-third of the total equity of the Company by the Series A Regulatory Group, and the requirements of Section 2(b).

3. Exercise of Warrant; Term. (a) To the extent permitted by applicable laws and regulations, the right to purchase the Shares pursuant to this Warrant is exercisable, in whole or in part by the Warrantholder, at any time or from time to time after the execution and delivery of this Warrant by the Company, on the date hereof, but in no event later than 11:59 p.m., New York City time, on the seventh (7^th) anniversary of the date of issuance of the Warrant, by: (i) delivery to the Company (or such other office or agency of the Company as it may designate by notice in writing to the registered Warrantholder at the last address of the Warrantholder as it shall appear upon the warrant register of the Company) of a duly executed Notice of Exercise, the form of which is annexed hereto, in accordance with Section 20; and (ii) within three (3) trading days after the date said Notice of Exercise is delivered to the Company, payment to the Company of the aggregate Exercise Price in respect of the Shares thereby purchased by cash, certified or cashier’s check or wire transfer in immediately available funds to an account designated by the Company, unless the Warrantholder elects to exercise the cashless exercise procedure described in Section 3(b) below. Notwithstanding anything herein to the contrary, the Warrantholder shall not be required to physically surrender this Warrant to the Company until the Warrantholder has purchased all of the Shares available hereunder and the Warrant has been exercised in full in which case, the Warrantholder shall surrender this Warrant to the Company for cancellation within three (3) trading days after the date the final Notice of Exercise is delivered to the Company. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Shares available hereunder shall have the effect of lowering the outstanding number of Shares purchasable hereunder in an amount equal to the applicable number of Shares purchased. If the Warrantholder does not exercise this Warrant in its entirety, the Warrantholder will be entitled to receive from the Company within a reasonable time, and in any event not exceeding three (3) Business Days after the date of delivery of the applicable aggregate Exercise Price to the Company, a new warrant in substantially identical form and of the same tenor for the purchase of Shares equal to the difference between the number of Shares subject to this Warrant and the number of Shares as to which this Warrant is so exercised. The Warrantholder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following the purchase of a portion of the Shares hereunder, the number of Shares available for purchase hereunder at any given time may be less than the amount stated on the face hereof.

(b) This Warrant may also be exercised, in whole or in part, at such time by means of a “cashless exercise” in which the Warrantholder shall be entitled to receive a certificate for the number of Shares equal to the quotient obtained by dividing [(A-B)*(X)] by (A), where:

(A) = the Market Price on the trading day immediately preceding the date on which the Warrantholder elects to exercise this Warrant by means of a “cashless exercise,” as set forth in the applicable Notice of Exercise;

(B) = the Exercise Price; and

(X) = the number of Shares that would be issuable upon exercise of this Warrant in accordance with the terms of this Warrant if such exercise were by means of a cash exercise rather than a cashless exercise.

(c) Notwithstanding anything to the contrary, the Company shall not issue any shares of Common Stock upon the exercise of this Warrant if the issuance of such shares of Common Stock (taken together with each issuance of such shares of Common Stock (1) upon the conversion of the Series A Preferred Stock in accordance with the Certificate of Designation, Preferences and Rights of Series A

Preferred Stock or otherwise, (2) upon the conversion of the Series B Preferred Stock in accordance with the Certificate of Designation, Preferences and Rights of Series B Preferred Stock or otherwise, (3) upon the conversion of the Non-Voting Common Stock in accordance with the Certificate of Formation as amended by the Non-Voting Common Stock Certificate of Amendment or otherwise or (4) upon the exercise of the other Warrants pursuant to the Warrant Agreements) would exceed 19.9% of the total outstanding shares of Common Stock of the Company, or more than 19.9% of the total voting power of the Company’s securities, in each case immediately preceding the issuance of the Series A Preferred Stock and the Warrants pursuant to the Investment Agreement and the Warrant Agreements (the number of shares which may be issued without violating such limitation, the “Exchange Cap”), except that such limitation shall not apply in the event that the Company obtains the approval of its shareholders as required by the applicable rules of the Principal Trading Market for issuances of shares of Common Stock in excess of such amount. Until such approval is obtained, the holders of the Series A Preferred Stock, Series B Preferred Stock, Non-Voting Common Stock and Warrants (collectively, the “Existing Buyers” and each, individually, an “Existing Buyer”) shall not be permitted to convert Series A Preferred Stock, Series B Preferred Stock or Non-Voting Common Stock or exercise Warrants with respect to more than such Existing Buyer’s pro rata amount of such Exchange Cap (such amount, with respect to each Existing Buyer, its “Exchange Cap Allocation Amount”) determined based upon such Existing Buyer’s percentage ownership of the sum of (1) the aggregate number of shares of Common Stock issuable upon the conversion of all shares of Series A Preferred Stock, Series B Preferred Stock and/or Non-Voting Common Stock, plus (2) the aggregate number of shares of Common Stock issuable upon exercise of the Warrants. In the event that such Existing Buyer shall sell or otherwise transfer any of such Existing Buyer’s shares of Series A Preferred Stock, Series B Preferred Stock, Non-Voting Common Stock or Warrants, the transferee shall be allocated a pro rata portion of such Existing Buyer’s Exchange Cap Allocation Amount with respect to such portion of such Series A Preferred Stock, Series B Preferred Stock, Non-Voting Common Stock and Warrants so transferred, and the restrictions of the prior sentence shall apply to such transferee with respect to the portion of the Exchange Cap Allocation Amount so allocated to such transferee. Upon conversion and exercise in full of such Existing Buyer’s Series A Preferred Stock, Series B Preferred Stock, Non-Voting Common Stock and Warrants, the difference (if any) between such Existing Buyer’s Exchange Cap Allocation Amount and the number of shares of Common Stock actually issued to such Existing Buyer upon such Existing Buyer’s conversion in full of such Series A Preferred Stock, Series B Preferred Stock, Non-Voting Common Stock and Warrants shall be allocated to the respective Exchange Cap Allocation Amounts of the remaining Existing Buyers of Series A Preferred Stock, Series B Preferred Stock, Non-Voting Common Stock and Warrants on a pro rata basis in proportion to the relative Exchange Cap Allocation Amounts of such Existing Buyers.

4. Issuance of Shares; Authorization. Certificates for Shares issued upon exercise of this Warrant will be issued in such name or names as the Warrantholder may designate and will be delivered to such named Person or Persons within a reasonable time, not to exceed three (3) Business Days after the date of delivery of the applicable aggregate Exercise Price to the Company. In lieu of delivering certificates, the Company may issue Shares issued upon exercise of this Warrant electronically in book-entry form, in which case a statement of book-entry interests will be delivered to the Warrantholder within the aforementioned period. The Company hereby represents and warrants that any Shares issued upon the exercise of this Warrant in accordance with the provisions of Section 3 and all other provisions of this Warrant will be duly and validly authorized and issued, fully paid and nonassessable and free from all taxes, liens and charges (other than liens or charges created by the Warrantholder or taxes in respect of any transfer occurring contemporaneously therewith). The Company agrees that the Shares so issued will be deemed to have been issued to the Warrantholder as of the close of business on the date on which payment of the aggregate Exercise Price is delivered to the Company in accordance with the terms of this Warrant, notwithstanding that the stock transfer books of the Company may then be closed or certificates representing such Shares may not be actually delivered on such date. The Company will at all times hereafter reserve and keep available, out of its authorized but unissued Common Stock, solely for the purpose of providing for the exercise of this Warrant, the aggregate number of shares of Common Stock then issuable upon exercise of this Warrant. The Company will use commercially reasonable efforts to ensure that the Shares may be issued without violation of any applicable law or regulation.

5. No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon any exercise of this Warrant. In lieu of any fractional share to which the Warrantholder would otherwise be entitled, the Warrantholder shall be entitled to receive a cash payment in an amount equal to such fraction multiplied by the Market Price of the Common Stock on the date of exercise.

6. No Rights as Shareholders; Transfer Books. This Warrant does not entitle the Warrantholder to any voting rights or other rights as a shareholder of the Company prior to the date of exercise hereof. The Company will at no time close its transfer books against transfer of this Warrant in any manner which interferes with the timely exercise of this Warrant.

7. Charges, Taxes and Expenses. Issuance of certificates for Shares to the Warrantholder upon the exercise of this Warrant shall be made without charge to the Warrantholder for any issue or transfer tax or other incidental expense in respect of the issuance of such certificates, all of which taxes and expenses shall be paid by the Company.

8. Transfer/Assignment. Subject to compliance with applicable securities laws, without obtaining the consent of the Company to assign or transfer this Warrant, this Warrant and all rights hereunder are not transferable or assignable, in whole or in part, by the Warrantholder, except for a Permitted Transfer. Upon a Permitted Transfer, a new warrant shall be made and delivered by the Company, as promptly as reasonably practicable, of the same tenor and date as this Warrant but registered in the name of the transferee or assignee and if the Warrantholder’s entire interest is not being transferred or assigned, in the name of the Warrantholder, upon surrender of this Warrant, duly endorsed, to the office or agency of the Company described in Section 20. All expenses (other than stock transfer taxes) and other charges payable in connection with the preparation, execution and delivery of the new warrants pursuant to this Section 8 shall be paid by the Company. The Company may not assign any of its rights, or delegate any of its obligations, under this Warrant without the prior written consent of the Warrantholder (which consent may be withheld for any reason or no reason at all). This Warrant shall be binding upon and inure to the benefit of the Company, the Warrantholder and their respective successors and permitted assigns, and shall include, with respect to the Company, any Person succeeding the Company in a Business Combination or acquisition of all or substantially all of the Company’s assets, and in such case, all of the obligations of the Company hereunder shall survive such Business Combination or acquisition.

9. Exchange and Registry of Warrant. This Warrant is exchangeable, upon the surrender hereof by the Warrantholder to the Company, for a new warrant or warrants of like tenor and representing the right to purchase the same aggregate number of Shares. The Company shall maintain a registry showing the name and address of the Warrantholder (and any transferee or assignee that becomes a Warrantholder) as the registered holder of this Warrant. This Warrant may be surrendered for exchange or exercise, in accordance with its terms, at the office of the Company, and the Company shall be entitled to rely in all respects, prior to written notice to the contrary, upon such registry.

10. Loss, Theft, Destruction or Mutilation of Warrant. Upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant, and in the case of any such loss, theft or destruction, upon receipt of a bond, indemnity or security reasonably satisfactory to the Company, or, in the case of any such mutilation, upon surrender and cancellation of this Warrant, the Company shall make and deliver, in lieu of such lost, stolen, destroyed or mutilated Warrant, a new Warrant, in identical form, of like tenor and representing the right to purchase the same aggregate number of Shares as provided for in such lost, stolen, destroyed or mutilated Warrant.

11. Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall not be a Business Day, then such action may be taken or such right may be exercised on the next succeeding day that is a Business Day.

12. Rule 144 Information. For so long as the Company is subject to the reporting obligations of the Securities Act and the Exchange Act, the Company covenants that it will use its reasonable best efforts to timely file all reports and other documents required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations promulgated by the U.S. Securities and Exchange Commission (the “SEC”) thereunder, and it will use reasonable best efforts to take such further action as the Warrantholder may reasonably request, all to the extent required from time to time to enable the Warrantholder to sell this Warrant without registration under the Securities Act within the limitation of the exemptions provided by (i) Rule 144 or Regulation S under the Securities Act, as such rules may be amended from time to time, or (ii) any successor rule or regulation hereafter adopted by the SEC. Upon the written request of the Warrantholder, the Company will deliver to the Warrantholder a written statement that it has complied with such requirements.

13. Adjustments and Other Rights. The Exercise Price and the number of Shares issuable upon exercise of this Warrant pursuant to Section 3 shall be subject to adjustment from time to time as follows; provided, that no single event shall be subject to adjustment under more than one subsection of this Section 13 so as to result in duplication and the adjustment that has the highest value relative to the rights and interests of the Warrantholder shall be made; provided, further, that, notwithstanding any provision of this Warrant to the contrary, any adjustment shall be made to the extent (and only to the extent) that such adjustment would not cause or result in any Warrantholder and its Affiliates, collectively, being in violation of any applicable law, regulation or rule of any governmental authority or self-regulatory organization. Any adjustment (or portion thereof) prohibited pursuant to the foregoing proviso shall be postponed and implemented on the first date on which such implementation would not result in the condition described in such proviso.

(A) The Exercise Price and the number of Shares issuable upon exercise of this Warrant pursuant to Section 3 shall not be adjusted:

(i) for any Excluded Stock; or

(ii) for a change in the par value of Common Stock.

(B) Dividends, Distributions, Stock Splits, Subdivisions, Reclassifications or Combinations. If the Company shall (i) declare a dividend or make a distribution on its Common Stock in shares of Common Stock, (ii) split, subdivide or reclassify the outstanding shares of Common Stock into a greater number of shares, or (iii) combine or reclassify the outstanding Common Stock into a smaller number of shares, the number of Shares issuable upon exercise of this Warrant at the time of the record date for such dividend or distribution or the effective date of such split, subdivision, combination or reclassification shall be proportionately adjusted so that the Warrantholder after such date shall be entitled to purchase the number of shares of Common Stock which such Warrantholder would have owned or been entitled to receive on such date had this Warrant been exercised immediately prior to such date. In such event, the Exercise Price in effect at the time of the record date for such dividend or distribution or the effective date of such split, subdivision, combination or reclassification shall be adjusted to the number obtained by dividing (x) the product of (1) the number of Shares issuable upon the exercise of this Warrant before such adjustment and (2) the Exercise Price in effect immediately prior to the record or effective date, as the case may be, for such dividend, distribution, split, subdivision, combination or reclassification giving rise to this adjustment by (y) the new number of Shares issuable upon exercise of this Warrant determined pursuant to the immediately preceding sentence. Notwithstanding anything to the contrary herein, if the Company declares

a dividend or makes a distribution on its Common Stock in shares of Common Stock, the Warrantholder may elect, in its sole and absolute discretion, to participate in such dividend or distribution in lieu of receiving the adjustment to the Exercise Price as described in this Section 13(B). In the event of such an election, the dividend or distribution that the Warrantholder is entitled to receive shall be based on the amount of the dividend or distribution that the Warrantholder would have received if it had exercised this Warrant in its entirety immediately prior to the record date of such dividend or distribution, as applicable. For the avoidance of doubt, the election under this Section 13(B) shall have no effect on any provisions of this Warrant other than as expressly set forth in this Section 13(B).

(C) Other Distributions. In case the Company shall fix a record date for the making of a distribution to all holders of shares of its Common Stock (i) of shares of any class other than its Common Stock, (ii) of evidence of indebtedness of the Company or any Subsidiary of the Company, (iii) of other securities, assets or cash (excluding dividends or distributions referred to in Section 13(B)), or (iv) of rights or warrants (other than in connection with the adoption of a shareholder rights plan), in each such case, the Exercise Price in effect prior thereto shall be reduced immediately thereafter to the price determined by dividing (x) an amount equal to the difference resulting from (1) the number of shares of Common Stock outstanding on such record date multiplied by the Exercise Price per Share on such record date, less (2) the amount of cash and/or the Fair Market Value of said shares or evidences of indebtedness or securities or assets or rights or warrants to be so distributed, by (y) the number of shares of Common Stock outstanding on such record date; such adjustment shall be made successively whenever such a record date is fixed. In such event, the number of Shares issuable upon the exercise of this Warrant shall be increased to the number obtained by dividing (x) the product of (1) the number of Shares issuable upon the exercise of this Warrant before such adjustment, and (2) the Exercise Price in effect immediately prior to the issuance giving rise to this adjustment by (y) the new Exercise Price determined in accordance with the immediately preceding sentence. In the event that such distribution is not so made, the Exercise Price and the number of Shares issuable upon exercise of this Warrant then in effect shall be readjusted, effective as of the date when the Board determines not to distribute such shares, evidences of indebtedness, securities, assets, cash, rights or warrants, as the case may be, to the Exercise Price that would then be in effect and the number of Shares that would then be issuable upon exercise of this Warrant if such record date had not been fixed.

(D) Certain Repurchases of Common Stock. In case the Company effects a Pro Rata Repurchase of Common Stock, then the Exercise Price shall be reduced to the price determined by multiplying the Exercise Price in effect immediately prior to the Effective Date of such Pro Rata Repurchase by a fraction of which the numerator shall be (i) the product of (x) the number of shares of Common Stock outstanding immediately before such Pro Rata Repurchase and (y) the Market Price of a share of Common Stock on the trading day immediately preceding the first public announcement by the Company or any of its Affiliates of the intent to effect such Pro Rata Repurchase, minus (ii) the aggregate purchase price of the Pro Rata Repurchase, and of which the denominator shall be the product of (i) (x) the number of shares of Common Stock outstanding immediately prior to such Pro Rata Repurchase minus (y) the number of shares of Common Stock so repurchased and (ii) the Market Price per share of Common Stock on the trading day immediately preceding the first public announcement by the Company or any of its Affiliates of the intent to effect such Pro Rata Repurchase. In such event, the number of Shares issuable upon the exercise of this Warrant shall be increased to the number obtained by dividing (i) the product of (x) the number of Shares issuable upon the exercise of this Warrant before such adjustment, and (y) the Exercise Price in effect immediately prior to the Pro Rata Repurchase giving rise to this adjustment by (ii) the new Exercise Price determined in accordance with the immediately preceding sentence.

(E) Business Combinations. In case of any Business Combination, reorganization or reclassification of Common Stock (other than a reclassification of Common Stock referred to in Section 13(B)), or the sale, transfer or other disposal of all or substantially all of the Company’s property, assets or business to another Person, in each case which entitles the holders of Common Stock to receive

(either directly or upon subsequent liquidation) stock, securities or property (including cash) with respect to or in exchange for Common Stock, any Shares issued or issuable upon exercise of this Warrant after the date of such Business Combination or other event shall be exchangeable for the number of shares of stock or other securities or property (including cash) to which the Shares issuable (at the time of such Business Combination or other event) upon exercise of this Warrant immediately prior to the consummation of such Business Combination or other event would have been entitled to receive upon consummation of such Business Combination or other event; and in any such case, if necessary, the provisions set forth herein with respect to the rights and interests thereafter of the Warrantholder shall be appropriately adjusted so as to be applicable, as nearly as may reasonably be, to any shares of stock or other securities or property thereafter deliverable on the exercise of this Warrant. In determining the kind and amount of stock, securities or the property receivable upon consummation of such Business Combination or other event, if the holders of Common Stock have the right to elect the kind or amount of consideration receivable upon consummation of such Business Combination or other event, then the Warrantholder shall have the right to make a similar election upon exercise of this Warrant with respect to the number of shares of stock or other securities or property which the Warrantholder will receive upon exercise of this Warrant. In case of any such Business Combination or other event, the successor or acquiring Person (if other than the Company) shall expressly assume the due and punctual observance and performance of each and every covenant and condition of this Warrant to be performed and observed by the Company and all the obligations and liabilities hereunder.

(F) Dissolution, Total Liquidation or Winding Up. If at any time there is a voluntary or involuntary dissolution, total liquidation or winding-up of the Company, then the Company shall provide the Warrantholder with written notice of the date on which such dissolution, liquidation or winding-up shall take place (and, in any event, not less than thirty (30) days before any date set for definitive action). Such notice shall also specify the date as of which the record holders of shares of Common Stock shall be entitled to exchange their shares for securities, money or other property deliverable upon such dissolution, liquidation or winding-up, as the case may be. On such date, the Warrantholder shall be entitled to receive upon surrender of this Warrant the cash, securities or other property, less the aggregate Exercise Price for this Warrant then in effect, that the Warrantholder would have been entitled to receive had this Warrant been exercised immediately prior to such dissolution, liquidation or winding-up. Upon receipt of the cash, securities or other property, any and all rights of the Warrantholder to exercise this Warrant shall terminate in their entirety. If the cash, securities or other property distributable in the dissolution, liquidation or winding-up has a Fair Market Value which is less than the aggregate Exercise Price for this Warrant then in effect, this Warrant shall terminate and be of no further force or effect upon the dissolution, liquidation or winding-up.

(G) Rounding of Calculations; Minimum Adjustments. All calculations under this Section 13 shall be made to the nearest one-tenth (1/10th) of a cent or to the nearest one-hundredth (1/100th) of a share, as the case may be. Any provision of this Section 13 to the contrary notwithstanding, no adjustment in the Exercise Price or the number of Shares issuable upon the exercise of this Warrant shall be made if the amount of such adjustment would be less than $0.01 or one-tenth (1/10th) of a share of Common Stock, respectively, but any such amount shall be carried forward and an adjustment with respect thereto shall be made at the time of and together with any subsequent adjustment which, together with such amount and any other amount or amounts so carried forward, shall aggregate $0.01 or one-tenth (1/10th) of a share of Common Stock, respectively, or more.

(H) Timing of Issuance of Additional Common Stock Upon Certain Adjustments. In any case in which the provisions of this Section 13 shall require that an adjustment shall become effective immediately after a record date for an event, the Company may defer until the occurrence of such event (i) issuing to the Warrantholder of this Warrant exercised after such record date and before the occurrence of such event the additional Shares issuable upon such exercise by reason of the adjustment required by

such event over and above the Shares issuable upon such exercise before giving effect to such adjustment and (ii) paying to such Warrantholder any amount of cash in lieu of a fractional Share; provided, however, that the Company upon request shall deliver to such Warrantholder a due bill or other appropriate instrument evidencing such Warrantholder’s right to receive such additional Shares, and such cash, upon the occurrence of the event requiring such adjustment.

(I) Statement Regarding Adjustments. Whenever the Exercise Price or the number of Shares issuable upon exercise of this Warrant shall be adjusted as provided in this Section 13, the Company shall forthwith file at the principal office of the Company a statement showing in reasonable detail the facts requiring such adjustment and the Exercise Price that shall be in effect and the number of Shares issuable upon exercise of this Warrant after such adjustment, and the Company shall also cause a copy of such statement to be sent by mail, first class postage prepaid, to the Warrantholder at the address appearing in the Company’s records.

(J) Notice of Adjustment Event. In the event that the Company shall propose to take any action of the type described in this Section 13 (but only if the action of the type described in this Section 13 would result in an adjustment in the Exercise Price or the number of Shares issuable upon exercise of this Warrant or a change in the type of securities or property to be delivered upon exercise of this Warrant), the Company shall give notice to the Warrantholder, in the manner set forth in Section 13(I), which notice shall specify the record date, if any, with respect to any such action and the approximate date on which such action is to take place. Such notice shall also set forth the facts with respect thereto as shall be reasonably necessary to indicate the effect on the Exercise Price and the number, kind or class of shares or other securities or property which shall be deliverable upon exercise of this Warrant. In the case of any action which would require the fixing of a record date, such notice shall be given at least five (5) days prior to the date so fixed, and in case of all other action, such notice shall be given at least ten (10) days prior to the taking of such proposed action. Failure to give such notice, or any defect therein, shall not affect the legality or validity of any such action.

(K) No Impairment. The Company will not, by amendment of its certificate of formation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company.

(L) Proceedings Prior to Any Action Requiring Adjustment. As a condition precedent to the taking of any action which would require an adjustment pursuant to this Section 13, the Company shall take any action which may be necessary, including obtaining regulatory, stock exchange (if applicable) or shareholder approvals or exemptions, in order that the Company may thereafter validly and legally issue as fully paid and nonassessable all shares of Common Stock that the Warrantholder is entitled to receive upon exercise of this Warrant pursuant to this Section 13.

(M) Adjustment Rules. Any adjustments pursuant to this Section 13 shall be made successively whenever an event referred to herein shall occur. If an adjustment in the Exercise Price made hereunder would reduce the Exercise Price to an amount below zero, then such adjustment in Exercise Price made hereunder shall reduce the Exercise Price to zero.

14. Reserved.

15. Contest and Appraisal Rights. Upon each determination of Market Price or Fair Market Value, as the case may be, hereunder, the Company shall promptly give notice thereof to the Warrantholder, setting forth in reasonable detail the calculation of such Market Price or Fair Market Value, and the method and basis of determination thereof, as the case may be. If the Warrantholder shall disagree with such determination and shall, by notice to the Company given within fifteen (15) days after the Warrantholder’s receipt of the Company’s notice of such determination, elect to dispute such determination, such dispute shall be resolved through the Appraisal Procedure.
