Each share of Series B Preferred Stock has the designations, preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends, qualifications, or terms or conditions of redemption as described herein. Each share of Series B Preferred Stock is identical in all respects to every other share of Series B Preferred Stock.

Section 3. Dividends.

EXHIBIT B-4

Section 4. Liquidation.

(a) Rank. The Series B Preferred Stock will, with respect to rights upon liquidation, winding up and dissolution, rank (i) subordinate and junior in right of payment to all other securities of the Corporation which, by their respective terms, are senior to the Series B Preferred Stock or the Common Stock, and (ii) pari passu with the Common Stock pro rata on an as-converted basis. Not in limitation of anything contained herein, and for purposes of clarity, the Series B Preferred Stock is subordinated to the general creditors and subordinated debt holders of the Corporation, and the depositors of the Corporation’s bank subsidiaries, in any receivership, insolvency, liquidation or similar proceeding.

(b) Liquidation Distributions. In the event of any liquidation, dissolution or winding up of the affairs of the Corporation, whether voluntary or involuntary, Holders will be entitled to receive, for each share of Series B Preferred Stock, out of the assets of the Corporation or proceeds thereof (whether capital or surplus) available for distribution to shareholders of the Corporation, subject to the rights of any Persons to whom the Series B Preferred Stock is subordinate, a distribution (“Liquidation Distribution”) equal to (i) any authorized and declared, but unpaid, Dividends with respect to such share of Series B Preferred Stock at the time of such liquidation, dissolution or winding up, and (ii) the amount the Holder of such share of Series B Preferred Stock would receive in respect of such share if such share had been converted into shares of Common Stock at the then applicable conversion rate at the time of such liquidation, dissolution or winding up (assuming the conversion of all shares of Series B Preferred Stock at such time, without regard to any limitations on conversion of the Series B Preferred Stock). All Liquidation Distributions to the Holders and the holders of Common Stock set forth in clause (ii) above will be made pro rata to the Holders and the holders of Common Stock on an as-converted basis.

(c) Merger, Consolidation and Sale of Assets Not Liquidation.

Section 5. Conversion.

(a) General.

(i) Unless the shares of Series B Preferred Stock shall have previously been converted into shares of Non-Voting Common Stock pursuant to Section 5(a)(iii), and subject to Section 5(g), a Holder shall be permitted to convert, or upon the written request of the Corporation shall convert, shares of Series B Preferred Stock into shares of Common Stock at any time or from time to time, provided that upon such conversion the Holder, together with all Affiliates and BHCA Transferees of the Holder (or, with respect to a BHCA Transferee, such BHCA Transferee, its Affiliates, and the Holder from which it acquired its shares of Series B Preferred Stock), will not own or control in the aggregate more than 9.9% of the Common Stock (or of any class of Voting Securities issued by the Corporation), 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 Holder (including, for the avoidance of doubt, a BHCA Transferee that is a Holder) of Voting Securities of the Corporation. In any such conversion, each share of Series B Preferred Stock will convert initially into 44.44 shares of Common Stock, subject to adjustment as provided in Section 6 below.

EXHIBIT B-5

(ii) Unless the shares of Series B Preferred Stock shall have previously been converted into shares of Non-Voting Common Stock pursuant to Section 5(a)(iii), and subject to Section 5(g), each share of Series B Preferred Stock will automatically convert into 44.44 shares of Common Stock, without any further action on the part of any Holder, subject to adjustment as provided in Section 6, below, on the date a Holder transfers any shares of Series B Preferred Stock to a non-affiliate of the Holder in a Permitted Regulatory Transfer.

(iii) Effective as of the close of business on the Mandatory Conversion Date, and subject to Section 5(g), each share of Series B Preferred Stock will automatically convert into 44.44 shares of Non-Voting Common Stock, without any further action on the part of any Holder.

(iv) To effect any permitted conversion under Section 5(a)(i) or Section 5(a)(ii), the Holder shall surrender the certificate or certificates evidencing such shares of Series B Preferred Stock, duly endorsed, at the registered office of the Corporation, and provide written instructions to the Corporation as to the number of whole shares for which such conversion shall be effected, together with any appropriate documentation that may be reasonably required by the Corporation. Upon the surrender of such certificate(s), the Corporation will issue and deliver to such Holder (in the case of a conversion under Section 5(a)(i)) or such Holder’s transferee (in the case of a conversion under Section 5(a)(ii)) a certificate or certificates for the number of shares of Common Stock into which the Series B Preferred Stock has been converted and, in the event that such conversion is with respect to some, but not all, of the Holder’s shares of Series B Preferred Stock, the Corporation shall deliver to such Holder a certificate or certificate(s) representing the number of shares of Series B Preferred Stock that were not converted to Common Stock or Non-Voting Common Stock.

(v) Upon occurrence of the Mandatory Conversion Date, the Corporation shall promptly provide notice of such event and the resulting conversion of the Series B Preferred Stock to each Holder. Such notice shall provide instructions for the surrender to the Corporation of certificates for shares of Series B Preferred Stock held of record by such Holders for issuance of certificates representing shares of Non-Voting Common Stock into which the Series B Preferred Stock have been converted pursuant to Section 5(a)(iii).

(vi) All shares of Common Stock or Non-Voting Common Stock delivered upon conversion of the Series B Preferred Stock shall be duly authorized, validly issued, fully paid and non-assessable, free and clear of all liens, claims, security interests, charges and other encumbrances.

(b) Principal Market Regulation. Notwithstanding anything to the contrary, but subject to Sections 5(a) and 5(g), the Corporation shall not issue any shares of Common Stock upon the conversion of the Series B Preferred Stock 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 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 (3) upon the exercise of the Warrants pursuant to the Warrant Agreements) would exceed 19.9% of the total outstanding shares of Common Stock of

EXHIBIT B-6

the Corporation, or more than 19.9% of the total voting power of the Corporation’s securities, in each case immediately preceding the issuance of the Series A Preferred Stock and 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 Corporation 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.

(c) Reservation of Shares Issuable Upon Conversion. The Corporation will at all times reserve and keep available out of its authorized but unissued Common Stock and, when authorized, Non-Voting Common Stock solely for the purpose of effecting the conversion of the Series B Preferred Stock such number of shares of Common Stock or Non-Voting Common Stock as will from time to time be sufficient to effect the conversion of all outstanding Series B Preferred Stock; and if at any time the number of shares of authorized but unissued Common Stock or Non-Voting Common Stock (when authorized) will not be sufficient to effect the conversion of all then outstanding Series B Preferred Stock, the Corporation will take such action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued Common Stock or Non-Voting Common Stock to such number of shares as will be sufficient for such purpose.

(d) No Impairment. The Corporation 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 Corporation, but will at all times in good faith assist in the carrying out of all the provisions of this Section 5 and in the taking of all such actions as may be necessary or appropriate in order to protect the conversion rights of the Holders against impairment.

EXHIBIT B-7

(e) Compliance with Law. Prior to the delivery of any securities that the Corporation shall be obligated to deliver upon conversion of the Series B Preferred Stock, the Corporation shall use its reasonable best efforts to comply with any federal and state laws and regulations thereunder requiring the registration of such securities with, or any approval of or consent to the delivery thereof by, any governmental authority.

(f) Listing. The Corporation hereby covenants and agrees that, if at any time the Common Stock shall be traded on any national securities exchange, the Corporation will, if permitted by the rules of such exchange, list and keep listed, so long as the Common Stock shall be so listed on such exchange, all the Common Stock issuable upon conversion of the Series B Preferred Stock; provided, however, that if the rules of such exchange require the Corporation to defer the listing of such Common Stock until the first conversion of Series B Preferred Stock into Common Stock in accordance with the provisions hereof, the Corporation covenants to list such Common Stock issuable upon conversion of the Series B Preferred Stock in accordance with the requirements of such exchange at such time.

(g) Total Equity Limitation. Notwithstanding any other provision of this Certificate of Designation, the Corporation shall not permit a member of a Series A Regulatory Group to effect a conversion pursuant to this Section 5 (and the Series B Preferred Stock shall not be convertible) to the extent that, immediately following such conversion, the Series A Regulatory Group would own or control greater than one-third of the total equity of the Corporation, calculated in accordance with the regulations of the Board of Governors of the Federal Reserve System at 12 C.F.R. § 225.34.

Section 6. Adjustments.

(a) Combinations or Divisions of Common Stock. In the event that the Corporation at any time or from time to time will effect a division of the Common Stock into a greater number of shares (by stock split, reclassification or otherwise other than by payment of a Dividend in Common Stock or in any right to acquire the Common Stock), or in the event the outstanding Common Stock will be combined or consolidated, by reclassification, reverse stock split or otherwise, into a lesser number of shares of the Common Stock, then the dividend, liquidation, and conversion rights of each share of Series B Preferred Stock in effect immediately prior to such event will, concurrently with the effectiveness of such event, be proportionately decreased or increased, as appropriate.

(b) Reclassification, Exchange or Substitution. If the Common Stock is changed into the same or a different number of shares of any other class or classes of stock, whether by capital reorganization, reclassification or otherwise (other than a division or combination of shares provided for in Section 6(a) above), (1) the conversion ratio then in effect will, concurrently with the effectiveness of such transaction, be adjusted so that each share of the Series B Preferred Stock will be convertible into, in lieu of the number of shares of Common Stock which the Holders would otherwise have been entitled to receive, a number of shares of such other class or classes of stock

EXHIBIT B-8

Section 7. Reorganization, Mergers, Consolidations or Sales of Assets. If at any time or from time to time there will be a capital reorganization of the Common Stock (other than a subdivision, combination, reclassification or exchange of shares otherwise provided for in Section 6) or a merger or consolidation of the Corporation with or into another corporation, or the sale of all or substantially all the Corporation’s properties and assets to any other Person, then, as a part of such reorganization, merger, consolidation or sale, provision will be made so that the Holders will thereafter be entitled to receive upon conversion of the Series B Preferred Stock, the number of shares of stock or other securities or property of the Corporation, or of the successor company resulting from such merger or consolidation or sale, to which a holder of that number of shares of Common Stock deliverable upon conversion of the Series B Preferred Stock would have been entitled to receive on such capital reorganization, merger, consolidation or sale (without regard to any limitations on conversion of the Series B Preferred Stock).

Each share of Non-Voting Common Stock has the designations, preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends, qualifications, or terms or conditions of redemption as described herein.

EXHIBIT C-4

3. Dividends.

In the event that the Board of Directors does not declare or pay any Dividends with respect to shares of Common Stock, then the holders of Non-Voting Common Stock will have no right to receive any Dividends.

4. Liquidation.

(a) Rank. The Non-Voting Common Stock will, with respect to rights upon liquidation, winding up and dissolution, rank (i) subordinate and junior in right of payment to all other securities of the Corporation that, by their respective terms, are senior to the Non-Voting Common Stock or the Common Stock, and (ii) pari passu with the Common Stock.

EXHIBIT C-5

subordinate, a distribution (“Liquidation Distribution”) equal to (i) any authorized and declared, but unpaid, Dividends with respect to such share of Non-Voting Common Stock at the time of such liquidation, dissolution or winding up, and (ii) the amount the holder of such share of Non-Voting Common Stock would receive in respect of such share if such share had been converted into shares of Common Stock at the then applicable conversion rate at the time of such liquidation, dissolution or winding up (assuming the conversion of all shares of Non-Voting Common Stock at such time, without regard to any limitations on conversion of the Non-Voting Common Stock). All Liquidation Distributions to the holders of the Non-Voting Common Stock and Common Stock set forth in clause (ii) above will be made pro rata to the holders thereof.

(c) Merger, Consolidation and Sale of Assets Not Liquidation. For purposes of this Section 4, the merger or consolidation of the Corporation with any other corporation or other entity, including a merger or consolidation in which the holders of Non-Voting Common Stock receive cash, securities or other property for their shares, or the sale, lease or exchange (for cash, securities or property) of all or substantially all of the assets of the Corporation, will not constitute a liquidation, dissolution or winding up of the Corporation.

5. Conversion.

(a) General.

(i) Subject to Section 5(g) of this Paragraph D, a holder of Non-Voting Common Stock shall be permitted to convert, or upon the written request of the Corporation shall convert, shares of Non-Voting Common Stock into shares of Common Stock at any time or from time to time, provided that upon such conversion the holder, together with all Affiliates and BHCA Transferees of the holder (or, with respect to a BHCA Transferee, such BHCA Transferee, its Affiliates, and the holder from which it acquired its shares of Non-Voting Common Stock), will not own or control in the aggregate more than 9.9% of the Common Stock (or of any class of Voting Securities issued by the Corporation), 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 holder (including, for the avoidance of doubt, a holder that is a BHCA Transferee) of Voting Securities of the Corporation; provided further that the right to convert under this Section 5(a)(i) shall not be available to a transferee of shares of Non-Voting Common Stock with respect to a transfer other than a Permitted Regulatory Transfer. In any such conversion, each share of Non-Voting Common Stock will convert initially into one (1) share of Common Stock, subject to adjustment as provided in Section 6 below.

EXHIBIT C-6

(ii) On the date a holder of Non-Voting Common Stock transfers any shares of Non-Voting Common Stock to a non-affiliate of the holder in a Permitted Regulatory Transfer, each such share of Non-Voting Common Stock will automatically convert into one (1) share of Common Stock, without any further action on the part of any holder, subject to adjustment as provided in Section 6 below.

(iii) To effect any permitted conversion under Section 5(a)(i) or Section 5(a)(ii), the holder shall surrender the certificate or certificates evidencing such shares of Non-Voting Common Stock, duly endorsed, at the registered office of the Corporation, and provide written instructions to the Corporation as to the number of whole shares for which such conversion shall be effected, together with any appropriate documentation that may be reasonably required by the Corporation or the Exchange Agent. Upon the surrender of such certificate(s), the Corporation will, or will cause the Exchange Agent to, issue and deliver to such holder (in the case of a conversion under Section 5(a)(i)) or such holder’s transferee (in the case of a conversion under Section 5(a)(ii)) a certificate or certificates for the number of shares of Common Stock into which the Non-Voting Common Stock has been converted and, in the event that such conversion is with respect to some, but not all, of the holder’s shares of Non-Voting Common Stock, the Corporation will, or will cause the Exchange Agent to, deliver to such holder a certificate or certificate(s) representing the number of shares of Non-Voting Common Stock that were not converted to Common Stock.

(iv) All shares of Common Stock delivered upon conversion of the Non-Voting Common Stock shall be duly authorized, validly issued, fully paid and non-assessable, free and clear of all liens, claims, security interests, charges and other encumbrances.

(b) Principal Market Regulation. Notwithstanding anything to the contrary, but subject to Sections 5(a) and 5(g) of this Paragraph D, the Corporation shall not issue any shares of Common Stock upon the conversion of the Non-Voting Common Stock 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, or (3) upon the exercise of the Warrants pursuant to the Warrant Agreements) would

EXHIBIT C-7

exceed 19.9% of the total outstanding shares of Common Stock of the Corporation, or more than 19.9% of the total voting power of the Corporation’s securities, in each case immediately preceding the issuance of the Series A Preferred Stock and 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 Corporation 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.

EXHIBIT C-8

(c) Reservation of Shares Issuable Upon Conversion. The Corporation will at all times reserve and keep available out of its authorized but unissued Common Stock solely for the purpose of effecting the conversion of the Non-Voting Common Stock such number of shares of Common Stock as will from time to time be sufficient to effect the conversion of all outstanding Non-Voting Common Stock; and if at any time the number of shares of authorized but unissued Common Stock will not be sufficient to effect the conversion of all then outstanding Non-Voting Common Stock, the Corporation will take such action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued Common Stock to such number of shares as will be sufficient for such purpose.

(d) No Impairment. The Corporation 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 Corporation, but will at all times in good faith assist in the carrying out of all the provisions of this Section 5 and in the taking of all such actions as may be necessary or appropriate in order to protect the conversion rights of the holders of the Non-Voting Common Stock against impairment.

(e) Compliance with Law. Prior to the delivery of any securities that the Corporation shall be obligated to deliver upon conversion of the Non-Voting Common Stock, the Corporation shall use its reasonable best efforts to comply with any federal and state laws and regulations thereunder requiring the registration of such securities with, or any approval of or consent to the delivery thereof by, any governmental authority.

(f) Listing. The Corporation hereby covenants and agrees that, if at any time the Common Stock shall be traded on any national securities exchange, the Corporation will, if permitted by the rules of such exchange, list and keep listed, so long as the Common Stock shall be so listed on such exchange, all the Common Stock issuable upon conversion of the Non-Voting Common Stock; provided, however, that if the rules of such exchange require the Corporation to defer the listing of such Common Stock until the first conversion of Non-Voting Common Stock into Common Stock in accordance with the provisions hereof, the Corporation covenants to list such Common Stock issuable upon conversion of the Non-Voting Common Stock in accordance with the requirements of such exchange at such time.

(g) Total Equity Limitation. Notwithstanding any other provision of this Certificate of Formation, the Corporation shall not permit a member of a Series A Regulatory Group to effect a conversion pursuant to this Section 5 (and the Non-Voting Common Stock shall not be convertible) to the extent that, immediately following such conversion, the Series A Regulatory Group would own or control greater than one-third of the total equity of the Corporation, calculated in accordance with the regulations of the Board of Governors of the Federal Reserve System at 12 C.F.R. § 225.34.

EXHIBIT C-9

6. Adjustments.

(a) Combinations or Divisions of Common Stock. In the event that the Corporation at any time or from time to time will effect a division of the Common Stock into a greater number of shares (by stock split, reclassification or otherwise other than by payment of a Dividend in Common Stock or in any right to acquire the Common Stock), or in the event the outstanding Common Stock will be combined or consolidated, by reclassification, reverse stock split or otherwise, into a lesser number of shares of the Common Stock, then the dividend, liquidation, and conversion rights of each share of Non-Voting Common Stock in effect immediately prior to such event will, concurrently with the effectiveness of such event, be proportionately decreased or increased, as appropriate.

(b) Reclassification, Exchange or Substitution. If the Common Stock is changed into the same or a different number of shares of any other class or classes of stock, whether by capital reorganization, reclassification or otherwise (other than a division or combination of shares provided for in Section 6(a) above), (1) the conversion ratio then in effect will, concurrently with the effectiveness of such transaction, be adjusted so that each share of the Non-Voting Common Stock will be convertible into, in lieu of the number of shares of Common Stock which the holders of the Non-Voting Common Stock would otherwise have been entitled to receive, a number of shares of such other class or classes of stock equal to the product of (i) the number of shares of such other class or classes of stock that a holder of a share of Common Stock would be entitled to receive in such transaction and (ii) the number of shares of Common Stock into which such share of Non-Voting Common Stock is then convertible (without regard to any limitations on conversion of the Non-Voting Common Stock) immediately before that transaction and (2) the Dividend and Liquidation Distribution rights then in effect will, concurrently with the effectiveness of such transaction, be adjusted so that each share of Non-Voting Common Stock will be entitled to a Dividend and Liquidation Distribution right, in lieu of with respect to the number of shares of Common Stock which the holders of the Non-Voting Common Stock would otherwise have been entitled to receive, with respect to a number of shares of such other class or classes of stock equal to the product of (i) the number of shares of such other class or classes of stock that a holder of a share of Common Stock would be entitled to receive in such transaction and (ii) the number of shares of Common Stock into which such share of Non-Voting Common Stock is then convertible (without regard to any limitations on conversion of the Non-Voting Common Stock) immediately before that transaction.

EXHIBIT C-10

(c) Certificates as to Adjustments. Upon the occurrence of each adjustment or readjustment pursuant to this Section 6, the Corporation at its expense will promptly compute such adjustment or readjustment in accordance with the terms hereof and prepare and furnish to each holder of Non-Voting Common Stock a certificate executed by the Corporation’s President (or other appropriate officer) setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. The Corporation will, upon the written request at any time of any holder of Non-Voting Common Stock, but no more frequently than once per fiscal quarter, furnish or cause to be furnished to such holder a like certificate setting forth (i) such adjustments and readjustments, and (ii) the number of shares of Common Stock and the amount, if any, of other property which at the time would be received upon the conversion of the Non-Voting Common Stock.

7. Reorganization, Mergers, Consolidations or Sales of Assets. If at any time or from time to time there will be a capital reorganization of the Common Stock (other than a subdivision, combination, reclassification or exchange of shares otherwise provided for in Section 6) or a merger or consolidation of the Corporation with or into another corporation, or the sale of all or substantially all the Corporation’s properties and assets to any other Person, then, as a part of such reorganization, merger, consolidation or sale, provision will be made so that the holders of the Non-Voting Common Stock will thereafter be entitled to receive upon conversion of the Non-Voting Common Stock, the number of shares of stock or other securities or property of the Corporation, or of the successor company resulting from such merger or consolidation or sale, to which a holder of that number of shares of Common Stock deliverable upon conversion of the Non-Voting Common Stock would have been entitled to receive on such capital reorganization, merger, consolidation or sale (without regard to any limitations on conversion of the Non-Voting Common Stock), provided, however, that the Corporation shall exercise commercially reasonable efforts to provide that such stock, securities, or property shall be in a form and manner that satisfies the regulatory requirements of the holder of the Non-Voting Common Stock, including with respect to the voting rights thereof.

8. Redemption. Except to the extent a liquidation under Section 4 may be deemed to be a redemption, the Non-Voting Common Stock will not be redeemable at the option of the Corporation or any holder of Non-Voting Common Stock at any time. Notwithstanding the foregoing, the Corporation will not be prohibited from repurchasing or otherwise acquiring shares of Non-Voting Common Stock in voluntary transactions with the holders thereof, subject to compliance with any applicable legal or regulatory requirements, including applicable regulatory capital requirements. Any shares of Non-Voting Common Stock repurchased or otherwise acquired may be reissued as additional shares of Non-Voting Common Stock.

9. Voting Rights. The holders of Non-Voting Common Stock will not have any voting rights, except as may otherwise be permitted for securities that are Nonvoting Securities, as set forth in 12 C.F.R. § 225.2(q)(2), or any successor provision.

EXHIBIT C-11

10. Protective Provisions. So long as any shares of Non-Voting Common Stock are issued and outstanding, the Corporation will not, without obtaining the approval (by vote or written consent) of the holders of a majority of the issued and outstanding shares of Non-Voting Common Stock, alter or change the rights, preferences, privileges or restrictions provided for the benefit of the holders of the Non-Voting Common Stock so as to affect them adversely, or take any action that would have the effect of adversely changing any preference or any relative or other right provided for the benefit of the holders of the Non-Voting Common Stock. In the event that the Corporation offers to repurchase shares of Common Stock, the Corporation shall offer to repurchase shares of Non-Voting Common Stock pro rata based upon the number of shares of Common Stock such holders would be entitled to receive if such shares were converted into shares of Common Stock immediately prior to such repurchase.

11. Notices. All notices required or permitted to be given by the Corporation with respect to the Non-Voting Common Stock shall be in writing, and if delivered by first class United States mail, postage prepaid, to the holders of the Non-Voting Common Stock at their last addresses as they shall appear upon the books of the Corporation, shall be conclusively presumed to have been duly given, whether or not the holder actually receives such notice; provided, however, that failure to duly give such notice by mail, or any defect in such notice, to the holders of any stock designated for repurchase, shall not affect the validity of the proceedings for the repurchase of any other shares of Non-Voting Common Stock, or of any other matter required to be presented for the approval of the holders of the Non-Voting Common Stock.

12. Record Holders. To the fullest extent permitted by law, the Corporation will be entitled to recognize the record holder of any share of Non-Voting Common Stock as the true and lawful owner thereof for all purposes and will not be bound to recognize any equitable or other claim to or interest in such share or shares on the part of any other Person, whether or not it will have express or other notice thereof.

13. Term. The Non-Voting Common Stock shall have perpetual term unless converted in accordance with Section 5.

14. Replacement Certificates. In the event that any Certificate will have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by the Corporation or the Exchange Agent, the posting by such Person of a bond in such amount as the Corporation or the Exchange Agent may determine is necessary as indemnity against any claim that may be made against it with respect to such Certificate, the Corporation or the Exchange Agent, as applicable, will deliver in exchange for such lost, stolen or destroyed Certificate a replacement Certificate.

15. Other Rights. The shares of Non-Voting Common Stock have no preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends, qualifications, or rights, other than as set forth herein or as provided by applicable law.

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.
