5.1   Right to Convert . Subject to and upon compliance with the provisions of this Note, the Holder shall have the right, at the Holder's option, at any time prior to the close of business on the Maturity Date (except that, if the Holder shall have exercised repurchase rights under Sections 4.1 and 4.2 or the Company shall have exercised its redemption rights under Section 1.1, such conversion right shall terminate with respect to the portion of this Note to be repurchased or redeemed, as the case may be, at the close of business on the last Trading Day prior to the later of (x) the Optional Redemption Date or the date the Company is required to make such repurchase, as the case may be, or (y) the date the Company pays or deposits in accordance with Section 7.10 the applicable Repurchase Price or Optional Redemption Price unless in any such case the Company shall default in payment due upon repurchase or redemption hereof) to convert the principal amount of this Note, or any portion of such principal amount which is at least $10,000 (or such lesser principal amount of this Note as shall be outstanding at such time), plus accrued and unpaid interest, into that number of fully paid and non-assessable shares of Common Stock (as such shares shall then be constituted) obtained by dividing (1) the sum of (x) the principal amount of this Note or portion thereof being converted plus (y) accrued and unpaid interest on the portion of the principal amount of this Note being converted to the applicable Conversion Date plus (z) accrued and unpaid Default Interest, if any, on the amount referred to in the immediately preceding clause (y) to the applicable Conversion Date by (2) the Conversion Price in effect on the applicable Conversion Date, by giving a Conversion Notice in the manner provided in Section 5.2; provided, however, that, if at any time this Note is converted in whole or in part pursuant to this Section 5.1 and after the Charter Amendment is effected or required to be effected in accordance with the Company’s obligations under the Note Purchase Agreement, the Company does not have available for issuance upon such conversion as authorized and unissued shares or in its treasury at least the number of shares of Common Stock required to be issued pursuant hereto, then, at the election of the Holder made by notice from the Holder to the Company, this Note (or portion hereof as to which conversion has been requested), to the extent that sufficient shares of Common Stock are not then available for issuance upon conversion, shall be converted into the right to receive from the Company, in lieu of the shares of Common Stock into which this Note or such portion hereof would otherwise be converted and which the Company is unable to issue, payment in an amount equal to the product obtained by multiplying (x) the number of shares of Common Stock which the Company is unable to issue times (y) the arithmetic average of the Market Price for the Common Stock during the five consecutive Trading Days immediately prior to the applicable Conversion Date. Any such payment shall, for all purposes of this Note, be deemed to be a payment of principal plus a premium equal to the total amount payable less the principal portion of this Note converted as to which such payment is required to be made because shares of Common Stock are not then available for issuance upon such conversion. The Holder is not entitled to any rights of a holder of Common Stock until the Holder has converted this Note to Common Stock, and only to the extent this Note is deemed to have been converted to Common Stock under this Article V. For purposes of Sections 5.5 and 5.6, whenever a provision references the shares of Common Stock into which this Note (or a portion hereof) is convertible or the shares of Common Stock issuable upon conversion of this Note (or a portion hereof) or words of similar import, any determination required by such provision shall be made as if a sufficient number of shares of Common Stock were then available for issuance upon conversion in full of this Note.

5.2   Exercise of Conversion Privilege; Issuance of Common Stock on Conversion; No Adjustment for Interest or Dividends . (a) In order to exercise the conversion privilege with respect to this Note, the Holder shall give a Conversion Notice (or such other notice which is acceptable to the Company) to the Company and the Transfer Agent or to the office or agency designated by the Company for such purpose by notice to the Holder. A Conversion Notice may be given by telephone line facsimile transmission to the numbers set forth on the form of Conversion Notice.

(b)   As promptly as practicable, but in no event later than three Trading Days, after a Conversion Notice is given, the Company shall issue and shall deliver to the Holder or the Holder's designee the number of full shares of Common Stock issuable upon such conversion of this Note or portion hereof in accordance with the provisions of this Article and deliver a check or cash in respect of any fractional interest in respect of a share of Common Stock arising upon such conversion, as provided in Section 5.2(f) and, if applicable, any cash payment required pursuant to the proviso to the first sentence of Section 5.1 (which payment, if any, shall be paid no later than five Trading Days after the applicable Conversion Date).

(c)   Each conversion of this Note (or portion hereof) shall be deemed to have been effected on the applicable Conversion Date, and the person in whose name any certificate or certificates for shares of Common Stock shall be issuable upon such conversion shall be deemed to have become on such Conversion Date the holder of record of the shares represented thereby; provided, however, that if a Conversion Date is a date on which the stock transfer books of the Company shall be closed such conversion shall constitute the person in whose name the certificates are to be issued as the record holder thereof for all purposes on the next succeeding day on which such stock transfer books are open, but such conversion shall be at the Conversion Price in effect on the applicable Conversion Date.

(d)   The Company shall notify the Holder of any claim by the Company of manifest error in a Conversion Notice within two Trading Days after the Holder gives such Conversion Notice and no such claim of error shall limit or delay performance of the Company's obligation to issue upon such conversion the number of shares of Common Stock which are not in dispute. A Conversion Notice shall be deemed for all purposes to be in proper form unless the Company notifies the Holder by telephone line facsimile transmission within two Trading Days after a Conversion Notice has been given (which notice from the Company shall specify all defects in the Conversion Notice) and any Conversion Notice containing any such defect shall nonetheless be effective on the date given if the Holder promptly undertakes to correct all such defects. The Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of shares of Common Stock or other securities or property on conversion of this Note in a name other than that of the Holder, and the Company shall not be required to issue or deliver any such shares or other securities or property unless and until the person or persons requesting the issuance thereof shall have paid to the Company the amount of any such tax or shall have established to the satisfaction of the Company that such tax has been paid. The Holder shall be responsible for the amount of any withholding tax payable in connection with any conversion of this Note.

(e)   (1) If the Holder shall have given a Conversion Notice in accordance with the terms of this Note, the Company's obligation to issue and deliver the certificates for Common Stock shall be absolute and unconditional, irrespective of any action or inaction by the Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any person or any action to enforce the same, any failure or delay in the enforcement of any other obligation of the Company to the Holder, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the Holder or any other person of any obligation to the Company or any violation or alleged violation of law by the Holder or any other person, and irrespective of any other circumstance which might otherwise limit such obligation of the Company to the Holder in connection with such conversion; provided, however, that nothing herein shall limit or prejudice the right of the Company to pursue any such claim in any other manner permitted by applicable law. The occurrence of an event which requires an adjustment of the Conversion Price as contemplated by Section 5.3 shall in no way restrict or delay the right of the Holder to receive certificates for Common Stock upon conversion of this Note and the Company shall use its best efforts to implement such adjustment on terms reasonably acceptable to the Holder within two Trading Days of such occurrence.

(2)   If in any case the Company shall fail to issue and deliver the shares of Common Stock to the Holder in connection with a particular conversion of this Note within three Trading Days after the Holder gives the Conversion Notice for such conversion, in addition to any other liabilities the Company may have hereunder and under applicable law (A) the Company shall pay or reimburse the Holder on demand for all out-of-pocket expenses, including, without limitation, reasonable fees and expenses of legal counsel, incurred by the Holder as a result of such failure, (B) if as a result of such failure the Holder shall suffer any direct damages or liabilities from such failure (including, without limitation, margin interest and the cost of purchasing securities to cover a sale (whether by the Holder or the Holder's securities broker) or borrowing of shares of Common Stock by the Holder for purposes of settling any trade involving a sale of shares of Common Stock made by the Holder during the period beginning on the Issuance Date and ending on the date the Company delivers or causes to be delivered to the Holder such shares of Common Stock), then the Company shall upon demand of the Holder pay to the Holder an amount equal to the actual direct, out-of-pocket damages and liabilities suffered by the Holder by reason thereof which the Holder documents to the reasonable satisfaction of the Company, and (C) the Holder may by written notice (which may be given by mail, courier, personal service or telephone line facsimile transmission) or oral notice (promptly confirmed in writing), given at any time prior to delivery to the Holder of the shares of Common Stock issuable in connection with such exercise of the Holder's conversion right, rescind such exercise and the Conversion Notice relating thereto, in which case the Holder shall thereafter be entitled to convert that portion of this Note as to which such exercise is so rescinded and to exercise its other rights and remedies with respect to such failure by the Company. Notwithstanding the foregoing the Company shall not be liable to the Holder under clause (B) of the immediately preceding sentence to the extent the failure of the Company to deliver or to cause to be delivered such shares of Common Stock results from fire, flood, storm, earthquake, shipwreck, strike, war, acts of terrorism, crash involving facilities of a common carrier, acts of God, or any similar event outside the control of the Company (it being understood that the action or failure to act of the Transfer Agent shall not be deemed an event outside the control of the Company except to the extent resulting from fire, flood, storm, earthquake, shipwreck, strike, war, acts of terrorism, crash involving facilities of a common carrier, acts of God, or any similar event outside the control of the Transfer Agent or the bankruptcy, liquidation or reorganization of the Transfer Agent under any bankruptcy, insolvency or other similar law). The Holder shall notify the Company in writing (or by telephone conversation, confirmed in writing) as promptly as practicable following the third Trading Day after the Holder gives a Conversion Notice if the Holder becomes aware that such shares of Common Stock so issuable have not been received as provided herein, but any failure so to give such notice shall not affect the Holder's rights under this Note or otherwise. If the Holder shall have exercised the conversion right in any particular instance and either (1) the Company shall notify the Holder on or after the date the Holder gives such Conversion Notice that the shares of Common Stock issuable upon such conversion might not be delivered within three Trading Days after the date the Holder gives such Conversion Notice or (2) the Holder learns after the date which is three Trading Days after the date the Holder gives such Conversion Notice that the Holder has not received such shares of Common Stock, then, without releasing the Company of its obligations with respect thereto, from and after the Trading Day next succeeding the earlier of the events described in the preceding clauses (1) and (2) of this sentence the Holder shall make reasonable efforts not to sell shares of Common Stock in anticipation of receipt of such shares of Common Stock in a manner which is likely to increase materially the liability of the Company under clause (2) of the second preceding sentence.

(f)   No fractional shares of Common Stock shall be issued upon conversion of this Note but, in lieu of any fraction of a share of Common Stock which would otherwise be issuable in respect of such conversion, the Company may round the number of shares of Common Stock issued on such conversion up to the next highest whole share or may pay lawful money of the United States of America for such fractional share, based on a value of one share of Common Stock being equal to the Market Price of the Common Stock on the applicable Conversion Date.

5.3   Adjustment of Conversion Price . The Conversion Price shall be adjusted from time to time by the Company as follows:

(a)   In case the Company shall on or after the Issuance Date pay a dividend or make a distribution to all holders of the outstanding Common Stock in shares of Common Stock, the Conversion Price in effect at the opening of business on the date following the date fixed for the determination of stockholders entitled to receive such dividend or other distribution shall be reduced by multiplying such Conversion Price by a fraction of which the numerator shall be the number of shares of Common Stock outstanding at the close of business on the Record Date fixed for such determination and the denominator shall be the sum of such number of shares and the total number of shares constituting such dividend or other distribution, such reduction to become effective immediately after the opening of business on the day following the Record Date. If any dividend or distribution of the type described in this Section 5.3(a) is declared but not so paid or made, the Conversion Price shall again be adjusted to the Conversion Price which would then be in effect if such dividend or distribution had not been declared.

(b)   In case the Company shall on or after the Issuance Date issue rights or warrants (other than any rights or warrants referred to in Section 5.3(d)) to all holders of its outstanding shares of Common Stock entitling them (for a period expiring within 45 days after the date fixed for the determination of stockholders entitled to receive such rights or warrants) to subscribe for or purchase shares of Common Stock at a price per share less than the Current Market Price on the Record Date fixed for the determination of stockholders entitled to receive such rights or warrants, the Conversion Price shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect at the opening of business on the date after such Record Date by a fraction of which the numerator shall be the number of shares of Common Stock outstanding at the close of business on the Record Date plus the number of shares which the aggregate offering price of the total number of shares so offered would purchase at such Current Market Price, and the denominator shall be the number of shares of Common Stock outstanding on the close of business on the Record Date plus the total number of additional shares of Common Stock so offered for subscription or purchase. Such adjustment shall become effective immediately after the opening of business on the day following the Record Date fixed for determination of stockholders entitled to receive such rights or warrants. To the extent that shares of Common Stock are not delivered pursuant to such rights or warrants, upon the expiration or termination of such rights or warrants, the Conversion Price shall be readjusted to the Conversion Price which would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. In the event that such rights or warrants are not so issued, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such date fixed for the determination of stockholders entitled to receive such rights or warrants had not been fixed. In determining whether any rights or warrants entitle the holder to subscribe for or purchase shares of Common Stock at less than such Current Market Price, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received for such rights or warrants, the value of such consideration, if other than cash, to be determined by the Board of Directors.

(c)   In case the outstanding shares of Common Stock shall on or after the Issuance Date be subdivided into a greater number of shares of Common Stock, the Conversion Price in effect at the opening of business on the earlier of the day following the day upon which such subdivision becomes effective and the day on which “ex-” trading of the Common Stock begins with respect to such subdivision shall be proportionately reduced, and conversely, in case outstanding shares of Common Stock shall be combined into a smaller number of shares of Common Stock, the Conversion Price in effect at the opening of business on the earlier of the day following the day upon which such combination becomes effective and the day on which “ex-” trading of the Common Stock with respect to such combination begins shall be proportionately increased, such reduction or increase, as the case may be, to become effective immediately after the opening of business on the earlier of the day following the day upon which such subdivision or combination becomes effective and the day on which “ex-” trading of the Common Stock begins with respect to such subdivision or combination.

(d)   In case the Company shall on or after the Issuance Date, by dividend or otherwise, distribute to all holders of its Common Stock shares of any class of capital stock of the Company (other than any dividends or distributions to which Section 5.3(a) applies) or evidences of its indebtedness, cash or other assets (including securities, but excluding any rights or warrants referred to in Section 5.3(b) and dividends and distributions paid exclusively in cash and excluding any capital stock, evidences of indebtedness, cash or assets distributed upon a merger or consolidation to which Section 5.4 applies) (the foregoing hereinafter in this Section 5.3(d) called the “Securities”)), then, in each such case, subject to the second paragraph of this Section 5.3(d), the Conversion Price shall be reduced so that the same shall be equal to the price determined by multiplying the Conversion Price in effect immediately prior to the close of business on the Record Date with respect to such distribution by a fraction of which the numerator shall be the Current Market Price on such date less the fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution) on such date of the portion of the Securities so distributed applicable to one share of Common Stock and the denominator shall be such Current Market Price, such reduction to become effective immediately prior to the opening of business on the day following the Record Date; provided, however, that in the event the then fair market value (as so determined) of the portion of the Securities so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price on the Record Date, in lieu of the foregoing adjustment, adequate provision shall be made so that the Holder shall have the right to receive upon conversion of this Note (or any portion hereof) the am
