Section 16.                                      Expenses.  With respect to any Institutional Series A Holder, in the event (i) the Closing occurs, or (ii) the transactions contemplated hereby with respect to such Institutional Series A Holder are not consummated other than due to a breach by such Institutional Series A Holder of any of its obligations under this Agreement, the Company will reimburse such Institutional Series A Holder for its reasonable documented out-of-pocket expenses incurred in connection with the preparation and negotiation of this Agreement and the transactions contemplated hereby, including the reasonable fees and expenses of counsel incurred by such Institutional Series A Holder and its Affiliates in connection with the transactions contemplated hereby; provided, that the Company shall not be obligated to reimburse any Institutional Series A Holder for amounts in excess of $50,000.

Section 18.                                      Counterparts and Facsimiles.  For the convenience of the parties hereto, this Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original instrument, and all such counterparts will together constitute the same agreement.  Executed signature pages to this Agreement may be delivered by facsimile and such facsimiles will be deemed as sufficient as if actual signature pages had been delivered.

Section 19.                                      Joinder.  This Agreement contemplates that additional Persons may execute a Joinder subsequent to the date hereof and become Additional Series A Holders.  The terms of this Agreement shall be binding upon each Additional Series A Holder as of the date on which such Additional Series A Holder executes a Joinder and delivers it to the Company.

Section 20.                                      Specific Performance.  The parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms.  It is accordingly agreed that the parties shall be entitled to seek specific performance of the terms hereof, this being in addition to any other remedies to which they are entitled at law or equity.

Section 21.                                      Amendment; Waiver.  No amendment or waiver of any provision of this Agreement will be effective with respect to any party unless made in writing and signed by a duly authorized representative of such party; provided, however, that this Agreement may not be amended by either the Company or the Series A Holders in such a manner as to permit the waiver of the conditions set forth in Sections 5(a)(vii) and 5(b)(vi).  No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege.  The conditions to each party’s obligation to consummate the Closing are for the sole benefit of such party and may be waived by such party in whole or in part to the extent permitted by applicable law.  No waiver of any party to this Agreement, as the case may be, will be effective unless it is in a writing signed by a duly authorized representative of the waiving party that makes express reference to the provision or provisions subject to such waiver.  For purposes of this Section 21, the agreement of all of the Institutional Series A Holders with respect to any such amendment or waiver shall constitute the agreement of all the Series A Holders with respect to any such amendment or waiver.

Section 22.                                      Several and Not Joint Obligations.  For the avoidance of doubt, the obligations of each Series A Holder under this Agreement are several and not joint with the obligations of any other Series A Holder, and no Series A Holder shall be responsible for the performance of the obligations of any other Series A Holder under this Agreement.  Each Series A Holder shall be entitled to independently enforce its rights under this Agreement and the Company shall be entitled to independently enforce its rights under this Agreement with respect to each Series A Holder.

Section 5.                                            Payment Restrictions.  During any time that any shares of Series A Preferred Stock are outstanding, the Company shall not (i) declare or pay dividends on, make distributions with respect to, or redeem, purchase or acquire, or make a liquidation payment with respect to, or pay or make available monies for the redemption of, any Common Stock or other Junior Securities, or (ii) redeem, purchase or acquire, or make a liquidation payment with respect to, or pay or make available monies for the redemption of, any Parity Securities (otherwise than pursuant to pro rata offers to purchase all or any pro rata portion of such Parity Securities and the Series A Preferred Stock), unless in each case full dividends on all outstanding shares of the Series A Preferred Stock have been paid or (in the case of current dividends) declared and set aside for payment (except for (w) dividends or distributions paid in shares of, or options, warrants or rights to subscribe for or purchase shares of, Common Stock or other Junior Securities, (x) redemptions or purchases by conversion or exchange of Junior Securities for or into other Junior Securities, or of Parity Securities for or into other Parity Securities or Junior Securities, (y) purchases by the Company or its Affiliates as a broker, dealer, advisor, fiduciary, trustee or comparable capacity in connection with transactions effected by or for the account of customers of the Company or customers of any of its subsidiaries or in connection with the distribution or trading of such capital stock and (z) acquisitions of shares of Common Stock in respect of exercises of employee equity awards or any related tax withholding).  When dividends are not paid in full (or declared and a sum sufficient for such full payment is not so set apart) for any Dividend Period on the Series A Preferred Stock and any Parity Securities, dividends declared on the Series A Preferred Stock and Parity Securities (whether cumulative or non-cumulative) shall only be declared pro rata so that the amount of dividends declared per share on the Series A Preferred Stock and such Parity Securities shall in all cases bear to each other the same ratio that accrued dividends per share on the shares of the Series A Preferred Stock (but without, in the case of any non-cumulative preferred stock, accumulation of unpaid dividends for prior Dividend Periods) and such Parity Securities bear to each other.

Section 6.                                            Voting Rights.

(a)                                  The Holders of the Series A Preferred Stock shall vote together with the holders of Common Stock on all matters upon which the holders of Common Stock are entitled to vote. Each share of Series A Preferred Stock shall be entitled to such number of votes as the number of shares of Common Stock into which such share of Series A Preferred Stock is convertible pursuant to the Conversion Rate at the time of the record date for any such vote (provided that solely for the purposes of determining the number of votes to which each share of Series A Preferred Stock is entitled pursuant to this Section 6(a), the Conversion Price utilized in the definition of Conversion Rate shall be deemed to be $2.00, subject to adjustment in accordance with the provisions of Section 12 with the exception of subsection (b) thereof), and for the purpose of such calculation, shares of Common Stock sufficient for the full conversion of all shares of Series A Preferred Stock shall be deemed to be authorized for issuance under the Certificate of Incorporation on such date and shall be included in such calculation.

(b)                                 So long as any shares of Series A Preferred Stock are outstanding, the vote or consent of the Holders of a majority of the shares of Series A Preferred Stock at the time

A-7

outstanding, voting as a single class with all other classes and series of Parity Securities having similar voting rights then outstanding and with each series or class having a number of votes proportionate to the aggregate liquidation preference of the outstanding shares of such class or series, given in person or by proxy, either in writing without a meeting or by vote at any meeting called for the purpose, will be necessary to effect or validate:

(i)                                     any amendment, alteration or repeal of any provision of the Certificate of Incorporation (including this Certificate of Designations) that would alter or change the voting powers, preferences or special rights of the Series A Preferred Stock or any Parity Security;

(ii)                                  any amendment or alteration of the Certificate of Incorporation (including this Certificate of Designations) to authorize, create or increase, or to obligate the Company to authorize, issue or increase, the authorized amount of any Senior Securities that are convertible into shares of Common Stock; or

(iii)                               any merger or consolidation of the Company with or into any entity other than a corporation, or any merger or consolidation of the Company with or into any other corporation unless the surviving or resulting corporation, or a corporation controlling such corporation that issues shares or other securities in such merger or consolidation, will thereafter have no class or series of shares or other securities either authorized or outstanding ranking prior to the Series A Preferred Stock in the payment of dividends or in the distribution of assets on any liquidation, dissolution or winding up, except the same number of shares and the same amount of other securities with the same voting powers, preferences and special rights as the shares and securities of the Company respectively authorized and outstanding immediately before such merger or consolidation, and each share of Series A Preferred Stock outstanding immediately before such merger or consolidation is changed thereby into the same number of shares, with the same voting powers, preferences and special rights, of such corporation;

provided, however, that if any such amendment, alteration or repeal described above would adversely affect one or more but not all series of preferred stock with like voting rights (including the Series A Preferred Stock for this purpose), then only the series affected and entitled to vote shall vote as a class in lieu of all such series of preferred stock.

(c)                                  Notwithstanding anything to the contrary herein, Holders shall not have any voting rights if, at or prior to the effective time of the act with respect to which such vote would otherwise be required, all outstanding shares of Series A Preferred Stock shall have been converted in accordance with the terms of this Certificate of Designations.

Section 7.                                            Liquidation.

(a)                                  In the event the Company voluntarily or involuntarily liquidates, dissolves or winds up, subject to the rights of any creditors of the Company or any holders of Senior Securities or Parity Securities, the Holders at the time shall be entitled to receive liquidating distributions per share of Series A Preferred Stock in an amount equal to the greater of (i) the amount of the Liquidation Preference per share of Series A Preferred Stock and (ii) the amount that the Holders would have received in respect of the Conversion Securities issuable upon conversion of such share of Series A Preferred Stock had they converted such share of Series A

A-8

Preferred Stock immediately prior to such event, in each case out of assets legally available for distribution to the Company’s stockholders, before any distribution of assets is made to the holders of the Common Stock, any other Conversion Securities or any other Junior Securities.  After payment of the full amount of such liquidating distributions, Holders of the Series A Preferred Stock shall have no right or claim to any of the remaining assets of the Company.

(b)                                 In the event the assets of the Company available for distribution to stockholders upon any liquidation, dissolution or winding-up of the affairs of the Company, whether voluntary or involuntary, shall be insufficient to pay in full the amounts payable with respect to all outstanding shares of the Series A Preferred Stock and the corresponding amounts payable on any Parity Securities, Holders and the holders of such Parity Securities shall share ratably in any distribution of assets of the Company in proportion to the full respective liquidating distributions to which they would otherwise be respectively entitled.

(c)                                  The Company’s consolidation or merger with or into any other entity, the consolidation or merger of any other entity with or into the Company, or the sale of all or substantially all of the Company’s property or business will not constitute its liquidation, dissolution or winding up.

Section 8.                                            Automatic Conversion.

(a)                                  Subject to Sections 8(b), 8(c) and 8(d), each share of Series A Preferred Stock shall automatically convert effective as of                      [a.m.][p.m.] on the Mandatory Conversion Date into a number of shares of Voting Common Stock equal to the Conversion Rate (the “Mandatory Conversion”).

(b)                                 Notwithstanding anything to the contrary in this Certificate of Designations, no conversion pursuant to this Section 8 with respect to shares of the Series A Preferred Stock of any Holder shall occur unless, with respect to such Holder, the Applicable Regulatory Approval has been obtained and remains in effect.

(c)                                  Subject to Section 8(d), notwithstanding anything to the contrary in this Certificate of Designations, no conversion pursuant to this Section 8 with respect to shares of Series A Preferred Stock held by any Holder shall be permitted to the extent such conversion would result in such Holder owning, together with its Affiliates, more than 14.9% (or 9.9% in the case of Castle Creek and 19.9% in the case of Patriot) of the outstanding shares of Voting Common Stock after giving effect to such conversion, unless, with respect to Castle Creek and Relational, such Holder has received written confirmation from the Federal Reserve Board of its non-control determination as to the increase in such Holder’s post-conversion ownership of the Company’s Voting Common Stock to as high as         % and         % with respect to Castle Creek and Relational, respectively.

(d)                                 In the event that (i) the shares of Series A Preferred Stock held by any Holder and its Affiliates would represent upon conversion more than 14.9% (or 9.9% in the case of Castle Creek and 19.9% in the case of Patriot) of the outstanding shares of Voting Common Stock after giving effect to such conversion and taking into consideration any shares of Voting Common Stock otherwise beneficially owned by such Holder or any of its Affiliates (the number of shares

A-9

of Series A Preferred Stock representing shares of Voting Common Stock upon conversion in excess of such percentage, the “Excess Shares”) and (ii) any such Holder has not received written confirmation from the Federal Reserve Board of its non-control determination as to such Holder’s post-conversion ownership of the Company’s Voting Common Stock, up to       % in the case of Castle Creek and       % in the case of Relational, then for all purposes of this Section 8 such Excess Shares shall be converted into a number of shares of Non-Voting Common Stock equivalent to the number of shares of Voting Common Stock into which such Excess Shares would otherwise have been convertible (including, without limitation, taking into account any adjustments to such number of shares of Voting Common Stock that would have been issuable in respect of the Excess Shares required by Section 12).  In such event, (i) each reference in this Section 8 to shares of Voting Common Stock issuable upon conversion of the Series A Preferred Stock shall be deemed a reference to the applicable Conversion Security and (ii) for purposes of the adjustment provisions in Section 12, the number of shares of Common Stock outstanding at any given point of time shall include the number of shares of Non-Voting Common Stock then outstanding.

Section 9.                                            Conversion Procedures.

(a)                                  On the Mandatory Conversion Date, any shares of Series A Preferred Stock converted to Conversion Securities shall cease to be outstanding, in each case, subject to the right of Holders of such shares to receive Conversion Securities into which such shares of Series A Preferred Stock are convertible.

(b)                                 The Person or Persons entitled to receive the Conversion Securities issuable upon any such conversion shall be treated for all purposes as the record holder(s) of such Conversion Securities as of the close of business on the Mandatory Conversion Date. No allowance or adjustment, except as set forth in Section 12, shall be made in respect of dividends payable to holders of Conversion Securities of record as of any date prior to the Mandatory Conversion Date. Prior to the Mandatory Conversion Date, Conversion Securities issuable upon conversion of any shares of Series A Preferred Stock shall not be deemed outstanding for any purpose, and Holders of shares of Series A Preferred Stock shall have no rights with respect to Conversion Securities (including voting rights as applicable, rights to respond to tender offers for the Conversion Securities and rights to receive any dividends or other distributions on the Conversion Securities) by virtue of holding shares of Series A Preferred Stock.

(c)                                  Shares of Series A Preferred Stock duly converted in accordance herewith, or otherwise reacquired by the Company, shall resume the status of authorized and unissued preferred stock of the Company, undesignated as to series and available for future issuance.

(d)                                 In the event that a Holder of shares of Series A Preferred Stock shall not by written notice designate the name in which Conversion Securities to be issued upon conversion of such Series A Preferred Stock should be registered or the address to which the certificate or certificates representing such Conversion Securities should be sent, the Company shall be entitled to register such shares, and make such payment, in the name of the Holder of such Series A Preferred Stock as shown on the records of the Company and to send the certificate or certificates representing such Conversion Securities to the address of such Holder shown on the records of the Company.

A-10

Section 10.                                      Reservation of Conversion Securities.

(a)                                  The Company shall at all times reserve and keep available out of its authorized and unissued Conversion Securities or shares held in the treasury of the Company, solely for issuance upon the conversion of shares of Series A Preferred Stock as provided in this Certificate of Designations, free from any preemptive or other similar rights, such number of applicable Conversion Securities as shall from time to time be issuable upon the conversion of all the shares of Series A Preferred Stock then outstanding.  For purposes of this Section 10(a), the number of Conversion Securities that shall be deliverable upon the conversion of all outstanding shares of Series A Preferred Stock shall be computed as if at the time of computation all such outstanding shares were held by a single Holder.

(b)                                 Notwithstanding the foregoing, the Company shall be entitled to deliver upon conversion of shares of Series A Preferred Stock, as herein provided, Conversion Securities held in the treasury of the Company (in lieu of the issuance of authorized and unissued Conversion Securities), so long as any such treasury shares are free and clear of all liens, charges, security interests or encumbrances (other than liens, charges, security interests and other encumbrances created by the Holders).

(c)                                  All Conversion Securities delivered upon conversion of the Series A Preferred Stock shall be duly authorized, validly issued, fully paid and non-assessable, free and clear of all liens, claims, security interests and other encumbrances (other than liens, charges, security interests and other encumbrances created by the Holders).

(d)                                 Prior to the delivery of any securities that the Company shall be obligated to deliver upon conversion of the Series A Preferred Stock, the Company shall use its reasonable best efforts to comply with all 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.

(e)                                  The Company hereby covenants and agrees that, if at any time the Common Stock shall be listed on the NASDAQ Stock Market or any other national securities exchange or automated quotation system, the Company shall, if permitted by the rules of such exchange or automated quotation system, list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated quotation system, all Voting Common Stock issuable upon conversion of the Series A Preferred Stock and issuable upon conversion of any Non-Voting Common Stock; provided, however, that if the rules of such exchange or automated quotation system permit the Company to defer the listing of such Common Stock until the conversion of Series A Preferred Stock into Common Stock in accordance with the provisions hereof, the Company covenants to list such Common Stock issuable upon conversion of the Series A Preferred Stock in accordance with the requirements of such exchange or automated quotation system at such time.

Section 11.                                      Fractional Shares.

(a)                                  No fractional Conversion Securities shall be issued as a result of any conversion of shares of Series A Preferred Stock.

A-11

(b)                                 In lieu of any fractional Conversion Security otherwise issuable to a Holder in respect of conversion pursuant to Section 8, the Company shall at its option either (i) issue to such Holder a whole Conversion Security, or (ii) to save the Company the trouble, expense and inconvenience of issuing fractional shares, pay an amount in cash (computed to the nearest cent) equal to such fraction times the average Closing Price of the Voting Common Stock for the five consecutive Trading Days ending on the second Trading Day immediately preceding the Mandatory Conversion Date.

(c)                                  If more than one share of the Series A Preferred Stock is surrendered for conversion at one time by or for the same Holder, the number of full Conversion Securities issuable upon conversion thereof shall be computed on the basis of the aggregate number of shares of the Series A Preferred Stock so surrendered.

Section 12.                                      Anti-Dilution Adjustments.

(a)                                  Except as provided in Section 12(c), the Conversion Price shall be subject to the following adjustments:

(i)                                     Stock Dividends and Distributions.  If the Company pays dividends or other distributions on the Common Stock in shares of Common Stock, then the Conversion Price in effect immediately prior to the Ex-Date for such dividend or distribution will be multiplied by the following fraction:

Where,

OS0 =  the number of shares of Common Stock outstanding immediately prior to Ex-Date for such dividend or distribution.

OS1 =  the sum of the number of shares of Common Stock outstanding immediately prior to the Ex-Date for such dividend or distribution plus the total number of shares of Common Stock constituting such dividend or distribution.

For the purposes of this clause (i), the number of shares of Common Stock at the time outstanding shall not include treasury shares.  If any dividend or distribution described in this clause (i) is declared but not so paid or made, the Conversion Price shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to make such dividend or distribution, to such Conversion Price that would be in effect if such dividend or distribution had not been declared.

(ii)                                  Subdivisions, Splits and Combination of the Common Stock.  If the Company subdivides, splits or combines the shares of Common Stock, then the Conversion Price in effect immediately prior to the effective date of such share subdivision, split or combination will be multiplied by the following fraction:

A-12

Where,

OS0 = the number of shares of Common Stock outstanding immediately prior to the effective date of such share subdivision, split or combination.

OS1 = the number of shares of Common Stock outstanding immediately after the opening of business on the effective date of such share subdivision, split or combination.

For the purposes of this clause (ii), the number of shares of Common Stock at the time outstanding shall not include treasury shares.  If any subdivision, split or combination described in this clause (ii) is announced but the outstanding shares of Common Stock are not subdivided, split or combined, the Conversion Price shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to subdivide, split or combine the outstanding shares of Common Stock, to such Conversion Price that would be in effect if such subdivision, split or combination had not been announced.

(iii)                               Debt or Asset Distributions.  If the Company distributes to all holders of shares of Common Stock evidences of indebtedness, shares of capital stock, securities, cash or other assets (excluding any dividend or distribution referred to in clause (i) above, any dividend or distribution paid exclusively in cash, any consideration payable in connection with a tender or exchange offer made by the Company or any of its subsidiaries, and any dividend of shares of capital stock of any class or series, or similar equity interests, of or relating to a subsidiary or other business unit in the case of certain spin-off transactions as described below), in exchange for consideration in an amount less than the fair market value of the property so distributed then the Conversion Price in effect immediately prior to the Ex-Date for such distribution will be multiplied by the following fraction:

Where,

SP0 = the Current Market Price per share of Common Stock on such date.

FMV = the fair market value of the portion of the distribution applicable to one share of Common Stock on such date as determined by the Board of Directors.

In a “spin-off,” where the Company makes a distribution to all holders of shares of Common Stock consisting of capital stock of any class or series, or similar equity interests of, or relating to, a subsidiary or other business unit, the Conversion Price will be adjusted on the 15th Trading Day after the effective date of the distribution by multiplying such Conversion Price in effect immediately prior to such 15th Trading Day by the following fraction:

A-13

Where,

MP0 = the average of the Closing Prices of the Common Stock over the first ten Trading Days commencing on and including the fifth Trading Day following the effective date of such distribution.

MPS = the average of the Closing Prices of the capital stock or equity interests representing the portion of the distribution applicable to one share of Common Stock over the first ten Trading Days commencing on and including the fifth Trading Day following the effective date of such distribution, or, if not traded on a national or regional securities exchange or over-the-counter market, the fair market value of the capital stock or equity interests representing the portion of the distribution applicable to one share of Common Stock on such date as determined by the Board of Directors.

In the event that such distribution described in this clause (iii) is not so paid or made, the Conversion Price shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to pay or make such dividend or distribution, to the Conversion Price that would then be in effect if such dividend or distribution had not been declared.

(iv)                              Cash Distributions.  If the Company makes a distribution consisting exclusively of cash to all holders of the Common Stock, excluding (a) any cash dividend on the Common Stock to the extent a corresponding cash dividend is paid on the Series A Preferred Stock pursuant to Section 4(a)(ii), (b) any cash that is distributed in a Reorganization Event or as part of a “spin-off” referred to in clause (iii) above, (c) any dividend or distribution in connection with the Company’s liquidation, dissolution or winding up, and (d) any consideration payable in connection with a tender or exchange offer made by the Company or any of its subsidiaries, then in each event, the Conversion Price in effect immediately prior to the Ex-Date for such distribution will be multiplied by the following fraction:

Where,

SP0 = the Closing Price per share of Common Stock on the Trading Day immediately preceding the Ex-Date.

DIV = the amount per share of Common Stock of the dividend or distribution, as determined pursuant to the following paragraph.

In the event that any distribution described in this clause (iv) is not so made, the Conversion Price shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to pay such distribution, to the Conversion Price which would then be in effect if such distribution had not been declared.

A-14

(v)                                 Self Tender Offers and Exchange Offers.  If the Company or any of its subsidiaries successfully completes a tender or exchange offer for the Common Stock where the cash and the value of any other consideration included in the payment per share of the Common Stock exceeds the Closing Price per share of the Common Stock on the Trading Day immediately succeeding the expiration of the tender or exchange offer, then the Conversion Price in effect at the close of business on such immediately succeeding Trading Day will be multiplied by the following fraction:

Where,

SP0 = the Closing Price per share of Common Stock on the Trading Day immediately succeeding the expiration of the tender or exchange offer.

OS0 = the number of shares of Common Stock outstanding immediately prior to the expiration of the tender or exchange offer, including any shares validly tendered and not withdrawn.

OS1 = the number of shares of Common Stock outstanding immediately after the expiration of the tender or exchange offer.

AC = the aggregate cash and fair market value of the other consideration payable in the tender or exchange offer, as determined by the Board of Directors.

In the event that the Company, or one of its subsidiaries, is obligated to purchase shares of Common Stock pursuant to any such tender offer or exchange offer, but the Company, or such subsidiary, is permanently prevented by applicable law from effecting any such purchases, or all such purchases are rescinded, then the Conversion Price shall be readjusted to be such Conversion Price that would then be in effect if such tender offer or exchange offer had not been made.

(b)                                 The Company may make such decreases in the Conversion Price, in addition to any other decreases required by this Section 12, if the Board of Directors deems it advisable to avoid or diminish any income tax to holders of the Common Stock resulting from any dividend or distribution of shares of Common Stock (or issuance of rights or warrants to acquire shares of Common Stock) or from any event treated as such for income tax purposes or for any other reason.

(c)                                  (i) All adjustments to the Conversion Price shall be calculated to the nearest 1/10 of a cent.  No adjustment in the Conversion Price shall be required if such adjustment would be less than $0.01; provided, that any adjustments which by reason of this subparagraph are not required to be made shall be carried forward and taken into account in any subsequent adjustment; provided, further, that on the Mandatory Conversion Date adjustments to the Conversion Price will be made with respect to any such adjustment carried forward and which has not been taken into account before such date.

A-15

(ii)                                  No adjustment to the Conversion Price shall be made if Holders may participate in the transaction that would otherwise give rise to an adjustment, as a result of holding the Series A Preferred Stock (including without limitation pursuant to Section 4(a)), without having to convert the Series A Preferred Stock, as if they held the full number of shares of Common Stock into which a share of the Series A Preferred Stock may then be converted.

(iii)                               The Conversion Price shall not be adjusted:

(A)                              upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock under any plan;

(B)                                upon the issuance of any shares of Common Stock or rights or warrants to purchase those shares pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by the Company or any of its subsidiaries;

(C)                                upon the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security outstanding as of the Issue Date and not amended thereafter;

(D)                               for a change in the par value or no par value of Common Stock; or

(E)                                 for accrued and unpaid dividends on the Series A Preferred Stock, except to the extent set forth in the definition of Conversion Price.

(d)                                 Whenever the Conversion Price is to be adjusted in accordance with Section 12(a) or Section 12(b) (or the definition of Conversion Price), the Company shall:  (i) compute the Conversion Price in accordance with Section 12(a) or Section 12(b) (or the definition of Conversion Price), taking into account the one-cent threshold set forth in Section 12(c); (ii) as soon as reasonably practicable following the occurrence of an event that requires an adjustment to the Conversion Price pursuant to Section 12(a) or Section 12(b) (or the definition of Conversion Price), taking into account the one cent threshold set forth in Section 12(c) (or if the Company is not aware of such occurrence, as soon as reasonably practicable after becoming so aware), provide, or cause to be provided, a written notice to the Holders of the occurrence of such event; and (iii) as soon as reasonably practicable following the determination of the revised Conversion Price in accordance with Section 12(a) or Section 12(b) (or the definition of Conversion Price), provide, or cause to be provided, a written notice to the Holders setting forth in reasonable detail the method by which the adjustment to the Conversion Price was determined and setting forth the revised Conversion Price.

(e)                                  Notwithstanding anything to the contrary in this Section 12 or otherwise in this Certificate of Designations, the Company shall not take any action that would result in the Conversion Price being adjusted to below the then par value (if any) of the Conversion Securities deliverable upon conversion of the Series A Preferred Stock.  Additionally, under no circumstances will the number of Conversion Securities deliverable upon conversion of the Series A Preferred Stock exceed (when taken together with all other outstanding shares of

A-16

Common Stock) the applicable number of Conversion Securities that the Company is authorized to issue.

Section 13.                                      Replacement Certificates.

(a)                                  The Company shall replace any mutilated stock certificate at the Holder’s expense upon surrender of such stock certificate to the Company.  The Company shall replace stock certificates that become destroyed, stolen or lost at the Holder’s expense upon delivery to the Company of satisfactory evidence that the stock certificate has been destroyed, stolen or lost, together with any indemnity that may be required by the Company.

(b)                                 The Company shall not be required to issue any stock certificates representing the Series A Preferred Stock on or after the Mandatory Conversion Date.  In place of the delivery of a replacement certificate following the Mandatory Conversion Date, the Company, upon delivery of the evidence and indemnity described in clause (a) above, shall deliver the Conversion Securities, or evidence of book-entry record ownership of such Conversion Securities, pursuant to the terms of the Series A Preferred Stock formerly evidenced by the certificate.

Section 14.                                      Redemptions.  The Series A Preferred Stock shall not be redeemable either at the Company’s option or at the option of any Holder.

Section 15.                                      Reorganization Events.

(a)                                  In the event of:

(i)                                     any consolidation or merger of the Company with or into another Person, in each case pursuant to which the Common Stock will be converted into cash, securities or other property of the Company or another Person,

(ii)                                  any sale, transfer, lease or conveyance to another Person of all or substantially all of the property and assets of the Company, in each case pursuant to which the Common Stock will be converted into cash, securities or other property of the Company or another Person,

(iii)                               any reclassification of the Common Stock into securities including securities other than the Common Stock or

(iv)                              any statutory exchange of the outstanding shares of Common Stock for securities of another Person (other than in connection with a merger or acquisition) (any such event specified in clauses (i) through (iv), a “Reorganization Event”),

each share of Series A Preferred Stock outstanding immediately prior to such Reorganization Event shall, without the consent of Holders, remain outstanding but shall become convertible, at the option of the Holders, into the kind of securities, cash and other property receivable in such Reorganization Event by the holder (excluding the counterparty to the Reorganization Event or an affiliate of such counterparty) of that number of shares of Common Stock into which the share of Series A Preferred Stock would then be convertible assuming that on the date such option is

A-17

exercised the Applicable Regulatory Approval has been obtained and remains in effect (such securities, cash and other property, the “Exchange Property”).

(b)                                 In the event that holders of the shares of Common Stock have the opportunity to elect the form of consideration to be received in such transaction, the consideration that the Holders are entitled to receive shall be deemed to be the types and amounts of consideration received by the majority of the holders of the shares of Common Stock that affirmatively make an election.  The amount of Exchange Property receivable upon conversion of any Series A Preferred Stock in accordance with Section 8 shall be an amount equal to the Conversion Price in effect on the Mandatory Conversion Date.

(c)                                  The above provisions of this Section 15 shall similarly apply to successive Reorganization Events and the provisions of Section 12 shall apply to any shares of capital stock of the Company (or any successor) received by the holders of the Common Stock in any such Reorganization Event.

(d)                                 The Company (or any successor) shall, within 20 days of the occurrence of any Reorganization Event, provide written notice to the Holders of such occurrence of such event and of the kind and amount of the cash, securities or other property that constitutes the Exchange Property.  Failure to deliver such notice shall not affect the operation of this Section 15.

Section 16.                                      No Impairment.  The Company shall not amend its Certificate of Incorporation or participate in any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action for the purpose of avoiding or seeking to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company, but shall at all times in good faith assist in carrying out all such action as may be reasonably necessary or appropriate in order to protect the conversion rights of the holders of the Series A Preferred Stock against dilution or other impairment as provided herein.

Section 17.                                      Miscellaneous.

(a)                                  All notices referred to herein shall be in writing, and, unless otherwise specified herein, all notices hereunder shall be deemed to have been given upon the earlier of receipt thereof or three Business Days after the mailing thereof if sent by registered or certified mail (unless first-class mail shall be specifically permitted for such notice under the terms of this Certificate of Designations) with postage prepaid, addressed:  (i) if to the Company, to its office at 1331 17th Street Suite 345, Denver, CO 80202-1566, Attention:  Chief Financial Officer, or (ii) if to any Holder, to such Holder at the address of such Holder as listed in the stock record books of the Company, or (iii) to such other address as the Company or any such Holder, as the case may be, shall have designated by notice similarly given.
