CONVERSION

          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

-10-

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).

-11-

          (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.

-12-

          (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

-13-

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

-14-

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 amount of Securities such holder would have received had such holder converted this Note (or portion hereof) immediately prior to such

-15-

Record Date. In the event that such dividend or distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such dividend or distribution had not been declared. If the Board of Directors determines the fair market value of any distribution for purposes of this Section 5.3(d) by reference to the actual or when issued trading market for any Securities comprising all or part of such distribution, it must in doing so consider the prices in such market over the same period used in computing the Current Market Price, to the extent possible.

          Rights or warrants distributed by the Company to all holders of Common Stock entitling the holders thereof to subscribe for or purchase shares of the Company’s capital stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events (a “Trigger Event”): (i) are deemed to be transferred with such shares of Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of Common Stock, shall not be deemed to have been distributed for purposes of this Section 5.3 (and no adjustment to the Conversion Price under this Section 5.3 will be required) until the occurrence of the earliest Trigger Event. If any such rights or warrants, including any such existing rights or warrants distributed prior to the Issuance Date, are subject to Trigger Events, upon the satisfaction of each of which such rights or warrants shall become exercisable to purchase different securities, evidences of indebtedness or other assets, then the occurrence of each such Trigger Event shall be deemed to be such date of issuance and record date with respect to new rights or warrants (and a termination or expiration of the existing rights or warrants without exercise by the holder thereof) (so that, by way of illustration and not limitation, the dates of issuance of any such rights shall be deemed to be the dates on which such rights become exercisable to purchase capital stock of the Company, and not the date on which such rights may be issued, or may become evidenced by separate certificates, if such rights are not then so exercisable). In addition, in the event of any distribution of rights or warrants, or any Trigger Event with respect thereto, that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Price under this Section 5.3 was made (1) in the case of any such rights or warrants which shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Price shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder or holders of Common Stock with respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights or warrants which shall have expired or been terminated without exercise by any holders thereof, the Conversion Price shall be readjusted as if such rights and warrants had not been issued.

          For purposes of this Section 5.3(d) and Sections 5.3(a) and (b), any dividend or distribution to which this Section 5.3(d) is applicable that also includes shares of Common Stock, or rights or warrants to subscribe for or purchase shares of Common Stock to which Section 5.3(b) applies (or both), shall be deemed instead to be (1) a dividend or distribution of the evidences of indebtedness, assets, shares of capital stock, rights or warrants other than such shares of Common Stock or rights or warrants to which Section 5.3(b) applies (and any Conversion Price reduction required by this Section 5.3(d) with respect to such dividend or distribution shall then be made) immediately followed by (2) a dividend or distribution of such

-16-

shares of Common Stock or such rights or warrants (and any further Conversion Price reduction required by Sections 5.3(a) and (b) with respect to such dividend or distribution shall then be made), except (A) the Record Date of such dividend or distribution shall be substituted as “the date fixed for the determination of stockholders entitled to receive such dividend or other distribution”, “Record Date fixed for such determination” and “Record Date” within the meaning of Section 5.3(a) and as “the date fixed for the determination of stockholders entitled to receive such rights or warrants”, “the Record Date fixed for the determination of the stockholders entitled to receive such rights or warrants” and “such Record Date” within the meaning of Section 5.3(b) and (B) any shares of Common Stock included in such dividend or distribution shall not be deemed “outstanding at the close of business on the Record Date fixed for such determination” within the meaning of Section 5.3(a).

          (e) In case the Company shall on or after the Issuance Date, by dividend or otherwise, distribute to all holders of its Common Stock cash (excluding any cash that is distributed upon a merger or consolidation to which Section 5.4 applies or as part of a distribution referred to in Section 5.3(d)) in an aggregate amount that, combined with (1) the aggregate amount of any other such distributions to all holders of its Common Stock made exclusively in cash within the 12 months preceding the date of payment of such distribution, and in respect of which no adjustment pursuant to this Section 5.3(e) has been made, and (2) the aggregate of any cash plus the fair market value (as determined by the Board of Directors, whose determination shall be conclusive and set forth in a Board Resolution) of consideration payable in respect of any Tender Offer by the Company or any Subsidiary for all or any portion of the Common Stock concluded within the 12 months preceding the date of payment of such distribution, and in respect of which no adjustment pursuant to Section 5.3(f) has been made, exceeds 10% of the product of (x) the Current Market Price on the Record Date with respect to such distribution times (y) the number of shares of Common Stock outstanding on such date, then, and in each such case, immediately after the close of business on such date, unless the Company elects to reserve such cash for distribution to the Holder upon the conversion of this Note (and shall have made adequate provision) so that the Holder will receive upon such conversion, in addition to the shares of Common Stock to which the Holder is entitled, the amount of cash which the Holder would have received if the Holder had, immediately prior to the Record Date for such distribution of cash, converted this Note into Common Stock, the Conversion Price shall be reduced so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the close of business on such Record Date by a fraction (i) the numerator of which shall be equal to the Current Market Price on the Record Date less an amount equal to the quotient of (x) the excess of such combined amount over such 10% and (y) the number of shares of Common Stock outstanding on the Record Date and (ii) the denominator of which shall be equal to the Current Market Price on the Record Date; provided, however, that in the event the portion of the cash so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price of the Common Stock 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 amount of cash the Holder would have received had the Holder converted this Note (or portion hereof) immediately prior to such Record Date. In the event that such dividend or distribution is not so paid or made, the Conversion Price shall again be adjusted to be

-17-

the Conversion Price which would then be in effect if such dividend or distribution had not been declared.

          (f) In case a Tender Offer on or after the Issuance Date made by the Company or any Subsidiary for all or any portion of the Common Stock shall expire and such Tender Offer (as amended upon the expiration thereof) shall require the payment to stockholders (based on the acceptance (up to any maximum specified in the terms of the Tender Offer) of Purchased Shares (as defined below)) of an aggregate consideration having a fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution) that combined together with (1) the aggregate of the cash plus the fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution), as of the expiration of such Tender Offer, of consideration payable in respect of any other Tender Offers, by the Company or any Subsidiary for all or any portion of the Common Stock expiring within the 12 months preceding the expiration of such Tender Offer and in respect of which no adjustment pursuant to this Section 5.3(f) has been made and (2) the aggregate amount of any distributions to all holders of the Company’s Common Stock made exclusively in cash within 12 months preceding the expiration of such Tender Offer and in respect of which no adjustment pursuant to Section 5.3(e) has been made, exceeds 10% of the product of (i) the Current Market Price as of the last time (the “Expiration Time”) tenders could have been made pursuant to such Tender Offer (as it may be amended) times (ii) the number of shares of Common Stock outstanding (including any tendered shares) at the Expiration Time, then, and in each such case, immediately prior to the opening of business on the day after the date of the Expiration Time, the Conversion Price shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to close of business on the date of the Expiration Time by a fraction of which the numerator shall be the number of shares of Common Stock outstanding (including any tendered shares) at the Expiration Time multiplied by the Current Market Price of the Common Stock on the Trading Day next succeeding the Expiration Time and the denominator shall be the sum of (x) the fair market value (determined as aforesaid) of the aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the Tender Offer) of all shares validly tendered and not withdrawn as of the Expiration Time (the shares deemed so accepted, up to any such maximum, being referred to as the “Purchased Shares”) and (y) the product of the number of shares of Common Stock outstanding (less any Purchased Shares) at the Expiration Time and the Current Market Price of the Common Stock on the Trading Day next succeeding the Expiration Time, such reduction (if any) to become effective immediately prior to the opening of business on the day following the Expiration Time. In the event that the Company is obligated to purchase shares pursuant to any such Tender Offer, but the Company is permanently prevented by applicable law from effecting any such purchases or all such purchases are rescinded, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such Tender Offer had not been made. If the application of this Section 5.3(f) to any Tender Offer would result in an increase in the Conversion Price, no adjustment shall be made for such Tender Offer under this Section 5.3(f).

          (g) (1) In case at any time on or after the Issuance Date the Company shall issue shares of its Common Stock or Common Stock Equivalents (collectively, the “Newly Issued Shares”), other than an issuance pro rata to all holders of its outstanding Common Stock

-18-

and other than an issuance in respect of which Section 5.3(h) is applicable, at a price below the Current Fair Market Value of the Common Stock at the time of such issuance, then following such issuance of Newly Issued Shares the Conversion Price shall be adjusted as provided in this Section 5.3(g). The Conversion Price following any such adjustment shall be determined by multiplying the Conversion Price immediately prior to such adjustment by a fraction, of which the numerator shall be the sum of (a) the number of shares of Common Stock outstanding immediately prior to the issuance of the Newly Issued Shares (calculated on a fully-diluted basis assuming the conversion of all options, warrants, purchase rights or convertible securities which are exercisable at the time of the issuance of the Newly Issued Shares) plus (b) the number of shares of Common Stock which the aggregate consideration, if any, received by the Company for the number of Newly Issued Shares would purchase at a price equal to the Current Fair Market Value of the Common Stock at the time of such issuance, and the denominator shall be the sum of (X) the number of shares of Common Stock outstanding immediately prior to the issuance of the Newly Issued Shares (calculated on a fully-diluted basis assuming the exercise or conversion of all options, warrants, purchase rights or convertible securities which are exercisable or convertible at the time of the issuance of the Newly Issued Shares) plus (Y) the number of Newly Issued Shares. The adjustment provided for in this Section 5.3(g) may be expressed as the following mathematical formula:

where:

C	=	aggregate consideration received by the Company for the Newly Issued Shares
N	=	number of Newly Issued Shares
O	=	number of shares of Common Stock outstanding (on a fully diluted basis, as described above) immediately prior to the issuance of the Newly Issued Shares
FMV	=	Current Fair Market Value of the Common Stock at the time of issuance of the Newly Issued Shares
CP	=	Conversion Price immediately prior to the issuance of the Newly Issued Shares
NCP	=	Conversion Price immediately after the issuance of the Newly Issued Shares

          (2) Notwithstanding the foregoing, no adjustment shall be made under this Section 5.3(g) by reason of:

          (A) the issuance by the Company of shares of Common Stock pro rata to all holders of the Common Stock so long as (i) any adjustment to the Conversion Price that is

-19-

required by Section 5.3(a) is made and (ii) the Company shall have given notice of such issuance thereof to the Holder pursuant to Section 5.6;

          (B) the issuance by the Company of the Notes, the Other Notes, the Warrants or the Other Warrants or shares of Common Stock upon conversion of this Note, or the Other Notes or upon exercise of the Warrants or the Other Warrants or in accordance with the terms hereof and thereof;

          (C) the issuance of Common Stock upon conversion, exercise or exchange of Common Stock Equivalents outstanding on the Issuance Date; or

          (D) the issuance of Common Stock and Common Stock Equivalents as consideration for acquisitions; provided that such shares in the aggregate amount to no more than 1,853,536 shares (as may be adjusted for stock splits, combinations, recapitalizations and the like); and provided further that, to the extent any shares are issued in excess of such amount, adjustment shall be made pursuant to this provision with respect to the issuance of all such shares.

          (h) (1) In case at any time on or after the Issuance Date the Company issues shares of Common Stock or Common Stock Equivalents at a price per share at which the Company sells such shares of Common Stock or the price per share at which the holders of such Common Stock Equivalents are entitled to acquire shares of Common Stock upon conversion or exercise thereof which is less than the Conversion Price in effect at the time of such issuance, then following such issuance the Conversion Price shall be reduced to the price per share (or weighted average price per share, if such shares are issued, or such Common Stock Equivalents may be converted or exercised, at different prices) at which such shares of Common Stock are issued or at which such Common Stock Equivalents may be exercised, if the same is lower than the Conversion Price in effect immediately prior to such issuance.

          (2) If any adjustment in the Conversion Price is made pursuant to this Section 5.3(h) in respect of any issuance of shares of Common Stock or Common Stock Equivalents such issuance pursuant to Section 5.3(g).

          (3) Notwithstanding the foregoing, no adjustment shall be made under this Section 5.3(h) by reason of:

          (A) the issuance by the Company of shares of Common Stock pro rata to all holders of the Common Stock so long as (i) any adjustment required by Section 5.3(a) is made and (ii) the Company shall have given notice thereof to the Holder pursuant to Section 5.6;

          (B) the issuance by the Company of the Notes, the Other Notes, the Warrants or the Other Warrants or the issuance by the Company of shares of Common Stock upon conversion of this Note or the Other Notes or upon exercise of the Warrants or the Other Warrants in accordance with the terms hereof and thereof;

-20-

          (C) the issuance of Common Stock upon conversion, exercise or exchange of Common Stock Equivalents outstanding on the Issuance Date;

          (D) the issuance by the Company of option grants for Common Stock or other of the Company’s equity securities for employees under a stock option, equity compensation or similar plan duly adopted by the Board of Directors in an amount not to exceed 1,853,536 shares (as may be adjusted for stock splits, combinations, recapitalizations and the like); provided that, to the extent any shares are issued in excess of such amount, adjustment shall be made pursuant to this provision with respect to the issuance of all such shares; or

          (E) the issuance of Common Stock and Common Stock Equivalents as consideration for acquisitions; provided that such shares in the aggregate amount to no more than 1,853,536 shares (as may be adjusted for stock splits, combinations, recapitalizations and the like); and provided further that, to the extent any shares are issued in excess of such amount, adjustment shall be made pursuant to this provision with respect to the issuance of all such shares.

          (i) The Company may make such reductions in the Conversion Price, in addition to those required by Sections 5.3(a), (b), (c), (d), (e), (f), (g) and (h), as the Board of Directors considers to be advisable to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock resulting from any dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for income tax purposes.

          (j) No adjustment in the Conversion Price shall be required unless such adjustment would require an increase or decrease of at least 1% in such price; provided, however, that any adjustments which by reason of this Section 5.3(j) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Article V shall be made by the Company and shall be made to the nearest cent or to the nearest one hundredth of a share, as the case may be.

          No adjustment need be made for a change in the par value of the Common Stock or from par value to no par value or from no par value to par value.

          (k) Whenever the Conversion Price is adjusted as herein provided, the Company shall promptly, but in no event later than five days thereafter, give a notice to the Holder setting forth the Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment, but which statement shall not include any information which would be material non-public information for purposes of the 1934 Act. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

          (l) In any case in which this Section 5.3 provides 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 Holder in connection with any conversion of this Note after such Record Date and before the occurrence of such event the additional shares of Common Stock issuable upon such conversion by reason of the adjustment required by such event over and above the Common Stock issuable upon such conversion before giving effect to such

-21-

adjustment and (ii) paying to such holder any amount in cash in lieu of any fraction pursuant to Section 5.2(f).

          (m) For purposes of this Section 5.3, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Company will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company other than dividends or distributions payable only in shares of Common Stock.

          5.4 Effect of Reclassification, Consolidation, Merger or Sale. (a) If any of the following events occur, namely (i) any reclassification or change of the outstanding shares of Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination), (ii) any consolidation, merger or combination of the Company with another corporation as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock, or (iii) any sale or conveyance of the properties and assets of the Company as, or substantially as, an entirety to any other corporation as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock, then the Company or the successor or purchasing Person, as the case may be, shall execute with the Holder a written agreement providing that (x) this Note shall be convertible into the kind and amount of shares of stock and other securities or property or assets (including cash) receivable upon such reclassification, change, consolidation, merger, combination, sale or conveyance by the holder of the number of shares of Common Stock issuable upon conversion of this Note in full (assuming, for such purposes, a sufficient number of authorized shares of Common Stock available to convert this Note) immediately prior to such reclassification, change, consolidation, merger, combination, sale or conveyance assuming such holder of Common Stock did not exercise such holder’s rights of election, if any, as to the kind or amount of securities, cash or other property receivable upon such consolidation, merger, statutory exchange, sale or conveyance (provided that, if the kind or amount of securities, cash or other property receivable upon such consolidation, merger, statutory exchange, sale or conveyance is not the same for each share of Common Stock in respect of which such rights of election shall not have been exercised (“non-electing share”), then for the purposes of this Section 5.4 the kind and amount of securities, cash or other property receivable upon such consolidation, merger, statutory exchange, sale or conveyance for each non-electing share shall be deemed to be the kind and amount so receivable per share by a plurality of the non-electing shares), (y) in the case of any such successor or purchasing Person, upon such consolidation, merger, combination, sale or conveyance such successor or purchasing Person shall be jointly and severally liable with the Company for the performance of all of the Company’s obligations under this Note and the Note Purchase Agreement and (z) if registration or qualification is required under the 1933 Act or applicable state law for the public resale by the Holder of such shares of stock and other securities so issuable upon conversion of this Note, such registration or qualification shall be completed prior to such reclassification, change, consolidation, merger, combination or sale.

For purposes of any computation under Section 5.3(f), the Current Market Price of the Common Stock on any date shall be deemed to be the arithmetic average of the daily Market Prices per share of Common Stock for such day and the next two succeeding Trading Days; provided, however, that if the “ex” date for any event (other than the Tender Offer requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 5.3(a), (b), (c), (d), (e), (f), (g) or (h), occurs on or after the Expiration Time for the Tender Offer requiring such computation and prior to the day in question, the Market Price for each Trading Day on and after the “ex” date for such other event shall be adjusted by multiplying such Market Price by the reciprocal of the fraction by which the Conversion Price is so required to be adjusted as a result of such other event.

-27-

such exchange or in such market after the time at which such subdivision or combination becomes effective, and (3) when used with respect to any Tender Offer means the first date on which the Common Stock trades, regular way, on such exchange or in such market after the Expiration Time of such Tender Offer.
