Effect of Certain Events.

(i)

Adjustment Due to Merger, Consolidation, Etc.  If, at any time when this Note is issued and outstanding, there shall be any merger, consolidation, exchange of shares, recapitalization, reorganization, or other similar event, as a result of which shares of Common Stock of the Company shall be changed into the same or a different number of shares of another class or classes of stock or securities of the Company or another entity, or in case of any sale or conveyance of all or substantially all of the assets of the Company other than in connection with a plan of complete liquidation of the Company, then the Holder of this Note shall thereafter have the right to receive upon conversion of the Holder’s Note, upon the basis and upon the terms and conditions specified herein and in lieu of th e shares of Common Stock immediately theretofore issuable upon conversion, such stock, securities or assets which the Holder would have been entitled to receive in such transaction had the Holder’s Note been converted in full immediately prior to such transaction (without regard to any limitations on conversion set forth herein), and in any such case appropriate provisions shall be made with respect to the rights and interests of the Holder of the Holder’s Note to the end that the provisions hereof (including, without limitation, provisions for adjustment of the Conversion Price and of the number of shares issuable upon conversion of the Note) shall thereafter be applicable, as nearly as may be practicable in relation to any securities or assets thereafter deliverable upon the conversion hereof.  The Company shall not effect any transaction described in this Section 6(f)(i) unless (a) it first gives, to the extent practicable, thirty (30) days prior written notice (but in any event at least fi fteen (15) days prior written notice) of the record date of the special meeting of stockholders to approve, or if there is no such record date, the consummation of, such merger, consolidation, exchange of shares, recapitalization, reorganization or other similar event or sale of assets (during which time the Holder shall be entitled to convert the Holder’s Note notwithstanding Section 6(a)(iii)) and (b) the resulting successor or acquiring entity (if not the Company) assumes by written instrument the obligations of this Section 6(f)(i).  The above provisions shall similarly apply to successive consolidations, mergers, sales, transfers or share exchanges.

(ii)

Adjustment Due to Distribution.  If, at any time when this Note is issued and outstanding, the Company shall declare or make any distribution of its assets (or rights to acquire its assets) to Holders of Common Stock as a dividend, stock repurchase, by way of return of capital or otherwise (including any dividend or distribution to the Company’s shareholders in cash or shares (or rights to acquire shares) of capital stock of a subsidiary (i.e., a spin-off)) (a “Distribution”), then the Holder of this Note shall be entitled, upon any conversion of the Holder’s Note after the date of record for determining shareholders entitled to such Distribution, to receive the amount of such assets which would have been payable to the Holder with respect to the shares of



- 8 -

-




Common Stock issuable upon such conversion had such Holder been the Holder of such shares of Common Stock on the record date for the determination of shareholders entitled to such Distribution.

(iii)

Adjustment Due to Dilutive Issuance.  If, at any time when any Notes are issued and outstanding, the Company issues or sells, or in accordance with this Section 6(f) is deemed to have issued or sold, any shares of Common Stock for no consideration or for a consideration per share (before deduction of reasonable expenses or commissions or underwriting discounts or allowances in connection therewith) less than the Conversion Price in effect on the date of such issuance (or deemed issuance) of such shares of Common Stock (a “Dilutive Issuance”), then immediately upon the Dilutive Issuance, the Conversion Price will be reduced to the price determined by multiplying the Conversion Price in effect immediately prior to the Dilutive Issuance by a fraction, (A) the numerator of whic h is an amount equal to the sum of (x) the number of shares of Common Stock actually outstanding immediately prior to the Dilutive Issuance, plus (y) the quotient of the aggregate consideration, calculated as set forth in Section 6(f)(iv) hereof, received by the Company upon such Dilutive Issuance divided by the Conversion Price in effect immediately prior to the Dilutive Issuance, and (B) the denominator of which is the Common Stock Deemed Outstanding (as defined below) immediately after the Dilutive Issuance; provided that only one adjustment will be made for each Dilutive Issuance.  The term “Common Stock Deemed Outstanding” shall mean the number of shares of Common Stock actually outstanding (not including shares of Common Stock held in the treasury of the Company), plus (i) pursuant to Section 6(f)(iv)(1) hereof, the maximum total number of shares of Common Stock issuable upon the exercise of Options, as of the date of such issuance or grant of such Options, if any, and (ii) pursua nt to Section 6(f)(iv)(2) hereof, the maximum total number of shares of Common Stock issuable upon conversion or exchange of Convertible Securities, as of the date of issuance of such Convertible Securities, if any.  No adjustment to the Conversion Price shall have the effect of increasing the Conversion Price above the Conversion Price in effect immediately prior to such adjustment.

(iv)

Effect on Conversion Price of Certain Events.  For purposes of determining the adjusted Conversion Price, the following will be applicable:

1.

Issuance of Rights or Options.  If the Company in any manner issues or grants any warrants, rights or options, whether or not immediately exercisable, to subscribe for or to purchase Common Stock or other securities convertible into or exchangeable for Common Stock (“Convertible Securities”) (such warrants, rights and options to purchase Common Stock or Convertible Securities are hereinafter referred to as “Options”) and the price per share for which Common Stock is issuable upon the exercise of such Options is less than the Conversion Price on the date of issuance or grant of such Options, then the maximum total number of shares of Common Stock issuable upon the exercise of all such Options will, as of the date of the issuance or grant of such Options, be deemed to be outstanding and to have been issued and sold by the Company for such price per share.  For purposes of the preceding sentence, the “price per share for which Common Stock is issuable upon the exercise of such Options” is determined by dividing (i) the total amount, if any, received or receivable by the



- 9 -

-




Company as consideration for the issuance or granting of all such Options, plus the minimum aggregate amount of additional consideration, if any, payable to the Company upon the exercise of all such Options, plus, in the case of Convertible Securities issuable upon the exercise of such Options, the minimum aggregate amount of additional consideration payable upon the conversion or exchange thereof at the time such Convertible Securities first become convertible or exchangeable, by (ii) the maximum total number of shares of Common Stock issuable upon the exercise of all such Options (assuming full conversion of Convertible Securities, if applicable).  No further adjustment to the Conversion Price will be made upon the actual issuance of such Common Stock upon the exercise of such Options or upon the conversion or exchan ge of Convertible Securities issuable upon exercise of such Options.

2.

Issuance of Convertible Securities.  If the Company in any manner issues or sells any Convertible Securities, whether or not immediately convertible (other than where the same are issuable upon the exercise of Options) and the price per share for which Common Stock is issuable upon such conversion or exchange is less than the Conversion Price on the date of issuance, then the maximum total number of shares of Common Stock issuable upon the conversion or exchange of all such Convertible Securities will, as of the date of the issuance of such Convertible Securities, be deemed to be outstanding and to have been issued and sold by the Company for such price per share.  For the purposes of the preceding sentence, the “price per share for which Common Stock is issuable upon such conversion or exchange” is determined by dividing (i) the tota l amount, if any, received or receivable by the Company as consideration for the issuance or sale of all such Convertible Securities, plus the minimum aggregate amount of additional consideration, if any, payable to the Company upon the conversion or exchange thereof at the time such Convertible Securities first become convertible or exchangeable, by (ii) the maximum total number of shares of Common Stock issuable upon the conversion or exchange of all such Convertible Securities.  No further adjustment to the Conversion Price will be made upon the actual issuance of such Common Stock upon conversion or exchange of such Convertible Securities.

3.

Change in Option Price or Conversion Rate.  If there is a change at any time in (i) the amount of additional consideration payable to the Company upon the exercise of any Options; (ii) the amount of additional consideration, if any, payable to the Company upon the conversion or exchange of any Convertible Securities; or (iii) the rate at which any Convertible Securities are convertible into or exchangeable for Common Stock (other than under or by reason of provisions designed to protect against dilution), the Conversion Price in effect at the time of such change will be readjusted to the Conversion Price which would have been in effect at such time had such Options or Convertible Securities still outstanding provided for such changed additional consideration or changed conversion rate, as the case may be, at the time initially granted, issued or sol d.

4.

Subdivision or Combination of Common Stock.  If the Company at any time subdivides (by any stock split, stock dividend, recapitalization, reorganization, reclassification or otherwise) the shares of Common Stock acquirable



- 10 -

-




hereunder into a greater number of shares, then, after such date of record for effecting such subdivision, the Conversion Price in effect immediately prior to such subdivision will be proportionately reduced.  If the Company at any time combines (by reverse stock split, recapitalization, reorganization, reclassification or otherwise) the shares of Common Stock acquirable hereunder into a smaller number of shares, then, after the date of record for effecting such combination, the Conversion Price in effect immediately prior to such combination shall be proportionately increased.

5.

Treatment of Expired Options and Unexercised Convertible Securities.  If, in any case, the total number of shares of Common Stock issuable upon exercise of any Option or upon conversion or exchange of any Convertible Securities is not, in fact, issued and the rights to exercise such Option or to convert or exchange such Convertible Securities shall have expired or terminated, the Conversion Price then in effect will be readjusted to the Conversion Price which would have been in effect at the time of such expiration or termination had such Option or Convertible Securities, to the extent outstanding immediately prior to such expiration or termination (other than in respect of the actual number of shares of Common Stock issued upon exercise or conversion thereof), never been issued.

6.

Calculation of Consideration Received.  If any Common Stock, Options or Convertible Securities are issued, granted or sold for cash, the consideration received therefor for purposes of the Holder’s Note will be the amount received by the Company therefor, before deduction of reasonable commissions, underwriting discounts or allowances or other reasonable expenses paid or incurred by the Company in connection with such issuance, grant or sale.  In case any Common Stock, Options or Convertible Securities are issued or sold for a consideration part or all of which shall be other than cash, the amount of the consideration other than cash received by the Company will be the fair value of such consideration, except where such consideration consists of securities, in which case the amount of consideration received by the Company will be the Marke t Price thereof as of the date of receipt.  In case any Common Stock, Options or Convertible Securities are issued in connection with any acquisition, merger or consolidation in which the Company is the surviving corporation, the amount of consideration therefor will be deemed to be the fair value of such portion of the net assets and business of the non-surviving corporation as is attributable to such Common Stock, Options or Convertible Securities, as the case may be.  The fair value of any consideration other than cash or securities will be determined in good faith by the Board of Directors of the Company.

7.

Exceptions to Adjustment of Conversion Price.  No adjustment to the Conversion Price will be made (A) upon the issuance of shares of Common Stock or options or warrants to purchase Common Stock to employees of the Company pursuant to any stock or option plan duly adopted by the Board of Directors of the Company (subject to the limitations on Options issued or issuable to the “Management Group” as defined in the Securities Purchase Agreement), or (B) the issuance of shares of Common Stock upon exercise of any of the Warrants.

(v)

Notice of Adjustments.  Upon the occurrence of each adjustment or readjustment of the Conversion Price as a result of the events described in this Section 6(f), the Company, at its expense, shall promptly compute such adjustment or readjustment and prepare and furnish to the Holder of this Note a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based.  The Company shall, upon the written request at any time of any Holder of Notes, furnish to such Holder a like certificate setting forth (i) such adjustment or readjustment, (ii) the Conversion Price at the time in effect and (iii) the number of shares of Common Stock and the amount, if any, of other securities or property which at the time would be rec eived upon conversion of such Holder’s Note.

g.

Status as Shareholder.  Upon submission of a Conversion Notice by the Holder of this Note, (i) the shares covered thereby (other than the shares, if any, which cannot be issued because their issuance would exceed such Holder’s allocated portion of the Reserved Amount) shall be deemed converted into shares of Common Stock and (ii) the Holder’s rights as a Holder of such converted portion of the Holder’s Note shall cease and terminate, excepting only the right to receive certificates for such shares of Common Stock and to any remedies provided herein or otherwise available at law or in equity to such Holder because of a failure by the Company to comply with the terms of the Holder’s Note.  Notwithstanding the foregoing, if a Holder has not received certificates for all shares of Common Stock prior to the third (3rd) Business Day after the De adline with respect to a conversion of any portion of the Holder’s Note for any reason, then the Holder may elect at such Holder’s option to regain the rights of a Holder of the Holder’s Note with respect to such attempted converted portions of the Holder’s Note and the Company shall, as soon as practicable, return such attempted converted Note to the Holder or, if the Note has not been surrendered, adjust its records to reflect that such portion of the Holder’s Note has not been converted.  In all cases, the Holder shall retain all of its rights and remedies for the Company’s failure to convert the Holder’s Note.
