2.2           Conversion Price.

(a)           Calculation of Conversion Price.                                                                           The term “Conversion Price” as used herein shall be equal to: (i) $.09 per share for the conversion of the initial $63,000 of the Principal Amount; and (ii) $10.00 per share for the conversion of any remaining balance of the Principal Amount and interest.

  The calculation of Conversion Price set forth in the previous paragraph shall be subject, as set forth in Section 2.7, to equitable adjustments upon the occurrence of certain events including, but not limited to, stock splits, reverse stock splits, stock dividends or rights offerings by the Borrower relating to the Borrower’s securities or the securities of any subsidiary of the Borrower or of Secured Parties (before or after the contemplated acquisition by Borrower of Earth LNG), combinations, recapitalization, reclassifications, extraordinary distributions and similar events until converted in full.

(b) Deficiency Upon Conversion.  Upon Conversion, in the event of any deficiency of any amounts due Holder hereunder, Borrower agrees to pay Holder, at Holder’s option any such deficiency in either cash or additional shares of Common Stock.  If the Holder elects, in its sole and absolute discretion to be paid such deficiency in Common Stock, such Common Stock shall be valued at the Conversion Price, then in effect. Nothing herein shall be deemed to limit the ability of Holder to collect any of the Principal Amount of this Note in cash or otherwise enforce any of its rights herein, as against the Borrower or any of the guarantors and Secured Parties or obligate the Holder to accept such shares in lieu of such deficiency.

2.3           Application of Conversion Amounts.  Any amounts converted by the Holder pursuant to Section 2.1 or paid by the Borrower shall be deemed to constitute payments of and applied, (i) first, any amounts owed other than accrued and unpaid interest (ii) second, against accrued and unpaid interest on the Principal Amount, and (iii) third, against the Principal Amount.

2.4           Authorized Shares.  For so long as the conversion right exists, the Borrower will reserve (and, from time to time, amend its Certificate of Incorporation so as to maintain reserved) from its authorized and unissued Common Stock a sufficient number of shares, free from preemptive rights, to provide for the issuance of Common Stock upon the full conversion of this Note and all other convertible securities of the Borrower, options or warrants.  As of the date of issuance of this Note, the Borrower has a sufficient number of authorized and unissued shares of Common Stock that have been duly reserved  for issuance upon conversion of this Note and such other securities  (the “Reserved Amount”).  The Reserved Amount shall be increased from time to time in accordance with the Borrower’s obligations pursuant to this Note and other agreements to which the Borrower may be obligated to issue shares (subject to the anti dilution provisions and other restrictions on such issuances herein).  The Borrower represents that upon issuance, such shares will be duly and validly issued, fully paid and non-assessable.  In addition, the if Borrower shall issue any securities or make any change to its capital structure which would change the number of shares of Common Stock into which this Note shall be convertible at their then current conversion price, the Borrower shall at the same time make proper provision so that thereafter there shall be a sufficient number of shares of Common Stock authorized and reserved, free from preemptive rights, for conversion of this Note.  The Borrower agrees that the issuance of this Note by Borrower and execution hereof by Borrower shall constitute full authority to its officers and agents who are charged with the duty of executing stock certificates to execute and issue the necessary certificates for shares of Common Stock in accordance with the terms and conditions of this Note. Concurrently with this Note, the Borrower, the Holder and the Holder’s transfer agent (the “Transfer Agent”) have entered into an escrow agreement and irrevocable transfer agent instruction letter (collectively the “Escrow Documents”) whereby the Borrower has deposited 700,000 shares of Common Stock  with the Transfer Agent to be held in escrow for the conversion of the initial $63,000 of the Principal Amount (as described above in Section 2.2(a)) pursuant to the terms of the Escrow Documents.

If, at any time a Holder of this Note submits a Notice of Conversion, and the Borrower does not have sufficient authorized but unissued shares of Common Stock available to effect such conversion in accordance with the provisions of this Article II (a “Conversion Default”), the Borrower shall issue to the Holder all of the shares of Common Stock which are then available to effect such conversion.  The portion of this Note which the Holder included in its Conversion Notice and which exceeds the amount which is then convertible into available shares of Common Stock (the “Excess Amount”) shall, notwithstanding anything to the contrary contained herein, not be convertible into Common Stock in accordance with the terms hereof until (and at the Holder’s option at any time after) the date additional shares of Common Stock are authorized by the Borrower to permit such conversion.  The Borrower shall use its best efforts to authorize a sufficient number of shares of Common Stock as soon as practicable following the earlier of (i) such time that the Holder notifies the Borrower or that the Borrower otherwise becomes aware that there are or likely will be insufficient authorized and unissued shares to allow full conversion thereof and (ii) a Conversion Default.  The Borrower shall send notice to the Holder of the authorization of additional shares of Common Stock, and the Authorization Date.

Nothing herein shall limit the Holder’s right to pursue actual damages against Borrower or any guarantor or Secured Party for the Borrowers failure to maintain a sufficient number of authorized shares of Common Stock or to repay this Note pursuant to the guarantees, and each Holder shall have the right to pursue all remedies available at law or in equity (including degree of specific performance and/or injunctive relief or under this Note.

2.5           Method of Conversion.

(a)           Mechanics of Conversion.                                                      Subject to Section 2.1, the Principal Amount and interest of this Note may be converted by the Holder in whole or in part at any time from time to time after the Issue Date, by (A) submitting to the Borrower a Notice of Conversion (by facsimile or other reasonable means of communication dispatched on the Conversion Date prior to 5:00 p.m., Pacific Standard Time) and (B) subject to Section 2.5(b), surrendering this Note at the principal office of the Borrower.

(b)           Surrender of Note Upon Conversion.  Notwithstanding anything to the contrary set forth herein, upon conversion of this Note in accordance with the terms hereof, the Holder shall not be required to physically surrender this Note to the Borrower unless the entire unpaid principal amount of this Note is so converted.  The Borrower shall maintain records showing the principal amount so converted and the dates of such conversions or shall use such other method, reasonably satisfactory to the Holder and the Borrower, so as not to require physical surrender of this Note upon each such conversion.  Notwithstanding the foregoing, if any portion of this Note is converted as aforesaid, the Holder may not transfer this Note unless the Holder first physically surrenders this Note to the Borrower, whereupon the Borrower will forthwith issue and deliver upon the order of the Holder a new Note of like tenor, registered as the Holder (upon payment by the Holder of any applicable transfer taxes) may request, representing in the aggregate the remaining unpaid principal amount of this Note.

(c)           Payment of Taxes.                                           The Borrower shall not be required to pay any tax which may be payable in respect of any transfer involved in the issue 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 (or in street name), and the Borrower or the Transfer Agent, as the case may be, shall not be required to issue or deliver any such shares or other securities or property unless and until the person or persons (other than the Holder or the custodian in whose street name such shares are to be held for the Holder’s account) requesting the issuance thereof shall have paid to the Borrower or the Transfer Agent, as the case may be, the amount of any such tax or shall have established to the satisfaction of the Transfer Agent, that such tax has been paid.

(d)           Delivery of Common Stock Upon Conversion.  Upon receipt by the Borrower from the Holder of a facsimile transmission, Adobe Acrobat electronic reproduction (or other reasonable means of reproduction of a signature) of a Notice of Conversion meeting the requirements for conversion as provided in this Section 2.5, the Borrower shall issue and deliver or cause to be issued and delivered to or upon the order of the Holder certificates for the Common Stock issuable upon such conversion within three (3) full business days (the “Deadline”) after such receipt (and, solely in the case of conversion of the entire unpaid principal amount hereof, surrender of this Note) in accordance with the terms hereof. The Borrower shall pay liquidated damages, in addition to other damages or lost profits resulting in the decline in price of the shares after the Deadline date (regardless of whether such shares could have been sold), of 1% of the number of shares not delivered for each 3 business day after the Deadline (i.e. 1% after six business days after the deadline, an aggregate of 2% after nine days, 3% after 12 days etc.), .

(e)           Obligation of Borrower to Deliver Common Stock.  Upon receipt by the Borrower of a Notice of Conversion, the Holder shall be deemed to be the Holder of record of the Common Stock issuable upon such conversion (the “Conversion Shares”), the outstanding principal amount and the amount of accrued and unpaid interest (and any other unpaid amounts) on this Note shall be reduced to reflect such conversion, and, unless the Borrower defaults on its obligations under this Article II, all rights with respect to the portion of this Note being so converted shall forthwith terminate except the right to receive the Common Stock or other securities, cash or other assets, as herein provided, on such conversion.  If the Holder shall have given a Notice of Conversion as provided herein, the Borrower’s obligation to issue and deliver the certificates for Common Stock shall be absolute and unconditional, irrespective of the absence of any action by the Holder to enforce the same, any waiver or consent with respect to any provision thereof, 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 Borrower to the holder of record, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the Holder of any obligation to the Borrower, and irrespective of any other circumstance which might otherwise limit such obligation of the Borrower to the Holder in connection with such conversion.  The Conversion Date with respect to a Notice of Conversion shall be the date on which the Notice of Conversion is given so long as the Notice of Conversion is received by the Escrow Agent before 5:00 p.m., Pacific Standard Time, on such date; or if received after 5:00 p.m. Pacific Standard Time, the Conversion Date shall be the following date.  Upon failure of the Borrower to timely deliver the shares of Common Stock issuable upon any such conversion, the Holder shall be entitled, as liquidated damages and not as a penalty, to a cash payment equal to 1.5% of the dollar amount of any such conversion for each 30-day period (or pro-rata for any portion thereof) following the Conversion Date until delivery of the Conversion Shares.

2.6           Concerning the Shares.  The shares of Common Stock issuable upon conversion of this Note may not be sold or transferred unless  (i) such shares are sold pursuant to an effective registration statement under the Act or (ii) the Borrower or its Transfer Agent shall have been furnished with an opinion of counsel (which opinion shall be in form, substance and scope customary for opinions of counsel in comparable transactions) to the effect that the shares to be sold or transferred may be sold or transferred pursuant to an exemption from such registration or (iii) such shares are sold or transferred pursuant to Rule 144 under the Act (or a successor rule) (“Rule 144”) or (iv) such shares are issued or transferred pursuant to a valid court order or other exemption from the registration requirements of the Act, or (v) such shares are transferred to an “affiliate” (as defined in Rule 144) of the Borrower who agrees to sell or otherwise transfer the shares only in accordance with this Section 2.6 and who is an Accredited Investor (as defined in the Act).  Except as otherwise provided in the Agreement (and subject to the removal provisions set forth below), until such time as the shares of Common Stock issuable upon conversion of this Note have been registered under the Act as contemplated by Article IV hereof or otherwise may be sold pursuant to Rule 144 or any other exemption, each certificate for shares of Common Stock issuable upon conversion of this Note that has not been so included in an effective registration statement or that has not been sold pursuant to an effective registration statement or issued pursuant to a valid exemption from the registration requirements of the Act, an exemption that permits removal of the legend, shall bear a legend substantially in the following form, as appropriate:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED.  THE SECURITIES MAY NOT BE SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER SAID ACT, OR AN OPINION OF COUNSEL IN FORM, SUBSTANCE AND SCOPE CUSTOMARY FOR OPINIONS OF COUNSEL IN COMPARABLE TRANSACTIONS, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT UNLESS SOLD PURSUANT TO RULE 144 UNDER SAID ACT.”

The legend set forth above shall be removed and the Borrower shall issue to the Holder a new certificate therefore free of any transfer legend if (i) the Borrower or its Transfer Agent shall have received an opinion of counsel, in form, substance and scope customary for opinions of counsel in comparable transactions, to the effect that a public sale or transfer of such Common Stock may be made without registration under the Act, including the provisions of Rule 144 and the shares are so sold or transferred, or (ii) in the case of the Common Stock issuable upon conversion of this Note, such security is registered for sale by the Holder under an effective registration statement filed under the Act or otherwise may be sold pursuant to Rule 144 without any restriction as to the number of securities as of a particular date that can then be immediately sold.  Nothing in this Note shall (i) limit the Borrower’s obligation under the Agreement or (ii) affect in any way the Holder’s obligations to comply with applicable prospectus delivery requirements upon the resale of the securities referred to herein.

2.7           Effect of Certain Events.

(a)           Effect of Merger, Consolidation, Etc.  The sale, conveyance or disposition of all or substantially all of the assets of the Borrower or of any Secured Party (as defined below) other than to the Borrower or a wholly-owned subsidiary of the Borrower, the effectuation by the Borrower or any Secured Party of a transaction or series of related transactions in which more than 50% of the voting power of the Borrower or of a Secured Party is disposed of, or the consolidation, merger or other business combination of the Borrower or Secured Party with or into any other Person or Persons when the Borrower or Secured Party is not the survivor shall:  (i) be deemed to be an Event of Default (as defined in Article IV) and, at the sole and absolute discretion of holder, may be treated pursuant to Section 2.7(b) hereof.  “Person” shall mean any individual, corporation, limited liability company, partnership, association, trust or other entity or organization.

(b)           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 Borrower shall be changed into the same or a different number of shares of another class or classes of stock or securities of the Borrower or another entity, or in case of any sale or conveyance of all or substantially all of the assets of the Borrower other than in connection with a plan of complete liquidation of the Borrower and other than to a wholly-owned subsidiary of the Borrower, then the Holder of this Note shall thereafter have the right to receive upon conversion of this Note, upon the basis and upon the terms and conditions specified herein and in lieu of the 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 this 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 this 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.  Neither the Borrower nor any of the Secured Parties may effect any transaction described in this Section 2.7(b) unless (a) it/they first gives, to the extent practicable, thirty (30) days prior written notice (but in any event at least fifteen (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 this Note or, if such transaction results in an Event of Default, declare such an Event of Default) and (b) the resulting successor or acquiring entity (if not the Borrower) assumes by written instrument the obligations of this Section 2.7(b) and all of the assets and business of the Borrower and Secured Parties are also being transferred to the acquiring entity and remain subject to the terms hereof.  The above provisions shall similarly apply to successive consolidations, mergers, sales, transfers or share exchanges.

(c)           Adjustment Due to Distribution. If the Borrower 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 Borrower’s shareholders in cash or shares (or rights to acquire shares) of capital stock of a any Secured Party or subsidiary (i.e., a spin-off)) (a “Distribution”), then the Holder of this Note shall be entitled, upon any conversion of this 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 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.

(d)           Reclassification, etc.  If the Borrower at any time shall, by reclassification or otherwise, change the Common Stock into the same or a different number of securities of any class or classes, this Note, as to the unpaid principal portion thereof and accrued interest thereon, shall thereafter be deemed to evidence the right to purchase an adjusted number of such securities and kind of securities as would have been issuable as the result of such change with respect to the Common Stock immediately prior to such reclassification or other change.

(e)           Stock Splits, Combinations and Dividends.  If the shares of Common Stock are subdivided or combined into a greater or smaller number of shares of Common Stock, or if a dividend is paid on the Common Stock in shares of Common Stock, the Conversion Price shall be proportionately reduced in case of subdivision of shares or stock dividend or proportionately increased in the case of combination of shares, in each such case by the ratio which the total number of shares of Common Stock outstanding immediately after such event bears to the total number of shares of Common Stock outstanding immediately prior to such event.

(f)           Purchase Rights/ Right of Participation in Future Offerings.   If, at any time when this Note is issued and outstanding, the Borrower issues any convertible securities or rights to purchase stock, warrants, securities or other property (the “Purchase Rights”) pro rata to the record holders of its Common Stock, then the Holder of this Note will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which such Holder could have acquired if such Holder had held the number of shares of Common Stock acquirable upon complete conversion of this Note (without regard to any limitations on conversion contained herein) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights or, if no such record is taken, the date as of which the record holders of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights.  In the event that a debt, convertible debt, equity, preferred equity or derivative security financing of any kind is conducted by the Borrower or any Secured Party at any time or from time to time while any portion of this Note is outstanding, the Holder shall have the right, but not obligation to (i) demand repayment of this Note in whole or in part to the closing date of such financing, or (ii) to convert and apply all or any portion of the Principal Amount or interest of this Note towards an equivalent dollar amount of subscription for securities in such offering(s) at the same terms and conditions as offered to all other investors and shall execute and be subject to and have the benefits of all of the agreements and rights granted to other investors in such offering(s).  The foregoing shall be a right only, and not obligation of the Holder and nothing herein shall be deemed to constitute a limitation or waiver on Holders other rights to anti dilution protections or other restrictive covenant benefits set forth herein.  In the event of application of a portion of the Note a replacement Note for the remaining portion of interest and Principal Amount not so applied towards a subscription in an offering, shall be issued to Holder reflecting the unpaid balance herein.

(g) Share Issuance.  So long as this Note is outstanding, if the Borrower shall issue any Common Stock, prior to the complete conversion of any convertible portion of this Note for a consideration less than $10.00 per share (as adjusted for stock splits, stock combinations or consolidations, stock dividends, mergers or similar transactions) the Conversion Price that would be in effect at the time of such issue for both Conversion Prices in effect, then, and thereafter successively upon each such issuance, the Conversion Prices shall be reduced by multiplying each of the Conversion Prices then in effect by a fraction, (A) the numerator of which is the dollar price per share for which the Common Stock or (or common stock equivalents) is sold in such offering or the dollar price for which such shares are issuable upon conversion or exchange or upon exercise of warrants or options and (B) the denominator of which is $10.  Notwithstanding the foregoing, the Conversion Price shall not be increased. For purposes of this adjustment, the issuance of any security or debt instrument or derivative instrument of the Borrower, carrying the right to convert such security or debt instrument into Common Stock or of any warrant, right or option to purchase Common Stock or the modification of any of the foregoing which may be outstanding shall result in an adjustment to the Conversion Price upon the modification or issuance of the above-described security, debt instrument, warrant, right, or option and again upon the issuance of shares of Common Stock upon exercise of such conversion or purchase rights if such issuance is at a price lower than the $10.00 per share (as adjusted for stock splits, stock combinations or consolidations, stock dividends, mergers or similar transactions).  The reduction of the Conversion Price described in this paragraph is in addition to the other rights of the Holder described in this Note.

(h)           Notice of Adjustments.  Upon the occurrence of each adjustment or readjustment of the Conversion Price as a result of the events described in the second sentence of Section 2.2(a) and/or this Section 2.7, the Borrower, at its expense, shall promptly compute such adjustment or readjustment and prepare and furnish to the Holder of a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based.  The Borrower shall, upon the written request at any time of the Holder, 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 received upon conversion of the Note.

                      (i)           Spin-Off.  If, at any time while any portion of this Note remains outstanding, the Borrower or any Secured Party spins off or otherwise divests itself of a part of its business or operations or disposes of all or of a part of its assets in a transaction (the "Spin Off") in which the Borrower, in addition to or in lieu of any other compensation received and retained by the Borrower for such business, operations or assets, causes securities of another entity (the "Spin Off Securities") to be issued to security holders of the Borrower, the Borrower shall cause to be reserved Spin Off Securities equal to the number thereof which would have been issued to the Holder had all of the convertible portion of Holder's Note outstanding on the record date (the "Record Date") for determining the amount and number of Spin Off Securities to be issued to security holders of the Borrower, (the "Outstanding Notes") been converted as of the close of business on the trading day immediately before the Record Date (the "Reserved Spin Off Shares"). Notwithstanding the foregoing, nothing herein shall be demand to permit any Spin Off which shall result in an immediate Event of Default.

2.8           Trading Market Limitations. Unless permitted by the applicable rules and regulations of the principal securities market on which the Common Stock is then listed or traded, in no event shall the Borrower issue upon conversion of or otherwise pursuant to this Note and the other notes or indebtedness, more than the maximum number of shares of Common Stock that the Borrower can issue pursuant to any rule of the principal United States securities market on which the Common Stock is then traded (the “Maximum Share Amount”), subject to equitable adjustment from time to time for stock splits, reverse stock splits, stock dividends, combinations, capital reorganizations and similar events relating to the Common Stock occurring after the date hereof.

BOTH PARTIES IRREVOCABLY WAIVE THE DEFENSE OF AN INCONVENIENT FORUM TO THE MAINTENANCE OF SUCH SUIT OR PROCEEDING.  BOTH PARTIES FURTHER AGREE THAT SERVICE OF PROCESS UPON A PARTY MAILED BY FIRST CLASS MAIL SHALL BE DEEMED IN EVERY RESPECT EFFECTIVE SERVICE OF PROCESS UPON THE PARTY IN ANY SUCH SUIT OR PROCEEDING.  NOTHING HEREIN SHALL AFFECT EITHER PARTY’S RIGHT TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW.  BOTH PARTIES AGREE THAT A FINAL NON-APPEALABLE JUDGMENT IN ANY SUCH SUIT OR PROCEEDING SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN OTHER JURISDICTIONS BY SUIT ON SUCH JUDGMENT OR IN ANY OTHER LAWFUL MANNER.  THE PARTY WHICH DOES NOT PREVAIL IN ANY DISPUTE ARISING UNDER THIS NOTE SHALL BE RESPONSIBLE FOR ALL FEES AND EXPENSES, INCLUDING ATTORNEYS’ FEES, INCURRED BY THE PREVAILING PARTY IN CONNECTION WITH SUCH DISPUTE.  THIS NOTE MAY BE ENFORCED BY, AND ANY ACTION MAY BE INITIATED BY, COLLATERAL AGENT ON BEHALF OF ANY HOLDERS.

5.7           Certain Amounts.  Whenever pursuant to this Note the Borrower is required to pay an amount in excess of the outstanding Principal Amount (or the portion thereof required to be paid at that time) plus accrued and unpaid interest plus any Default Interest, the Borrower and the Holder agree that the actual damages to the Holder from the receipt of cash payment on this Note may be difficult to determine and the amount to be so paid by the Borrower represents stipulated damages and not a penalty and is intended to compensate the Holder in part for loss of the opportunity to convert this Note and to earn a return from the sale of shares of Common Stock acquired upon conversion of this Note at a price in excess of the price paid for such shares pursuant to this Note.  The Borrower and the Holder hereby agree that such amount of stipulated damages is not plainly disproportionate to the possible loss to the Holder from the receipt of a cash payment without the opportunity to convert this Note into shares of Common Stock.

5.8           Maximum Payments.  Nothing contained herein shall be deemed to establish or require the payment of a rate of interest or other charges in excess of the maximum permitted by applicable law.  In the event that the rate of interest required to be paid or other charges hereunder exceed the maximum permitted by such law, any payments in excess of such maximum shall be credited against amounts owed by the Borrower to the Holder and thus refunded to the Borrower.

5.9           Allocations of Maximum Share Amount and Reserved Amount.  The Maximum Share Amount and Reserved Amount shall be allocated pro rata among the Holders of Notes issued pursuant to the Agreement based on the principal amount of such Notes issued to each Holder except as otherwise agreed by such Holders.  Each increase to the Maximum Share Amount and Reserved Amount shall be allocated pro rata among the Holders of Notes based on the principal amount of such Notes held by each Holder at the time of the increase in the Maximum Share Amount or Reserved Amount except as otherwise agreed by such Holders.  In the event a Holder shall sell or otherwise transfer any of such Holder’s Notes, each transferee shall be allocated a pro rata portion of such transferor’s Maximum Share Amount and Reserved Amount.  Except as otherwise agreed to by such Holders, any portion of the Maximum Share Amount or Reserved Amount which remains allocated to any person or entity which does not hold any Notes shall be allocated to the remaining Holders of Notes, pro rata based on the principal amount of such Notes then held by such Holders.

5.10           Damages Shares.  Any shares of Common Stock that may be issuable to the Holder pursuant to this Note in excess of the Conversion Shares (“Damages Shares”) shall be treated as Common Stock issuable upon conversion of this Note for all purposes hereof and shall be subject to all of the limitations and afforded all of the rights of the other shares of Common Stock issuable hereunder.

5.11           Denominations.  At the request of the Holder, upon surrender of this Note, the Borrower shall promptly issue new Notes in the aggregate outstanding principal amount hereof, in the form hereof, in such denominations as the Holder shall request.

4.12           Notice of Corporate Events.  Except as otherwise provided below, the Holder of this Note shall have no rights as a Holder of Common Stock unless and only to the extent that it converts this Note into Common Stock.  The Borrower shall provide the Holder with prior notification of any meeting or other corporate or company action of the Borrower’s shareholders (and copies of proxy materials and other information sent to shareholders).  

4.13           Remedies.  The Borrower acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder, by vitiating the intent and purpose of the transaction contemplated hereby.  Accordingly, the Borrower acknowledges that the remedy at law for a breach of its obligations under this Note will be inadequate and agrees, in the event of a breach or threatened breach by the Borrower of the provisions of this Note, that the Holder shall be entitled, in addition to all other available remedies at law as provided in Article III above, or in equity, and in addition to the penalties assessable herein, to an injunction or injunctions restraining, preventing or curing any breach of this Note and to enforce specifically the terms and provisions thereof, without the necessity of showing economic loss and without any bond or other security being required.  This Note is and shall be deemed an unconditional obligation of Borrower and Secured Parties and Guarantors for the payment of money only and, without limitation to any other remedies Holder may have, may be enforced against either or both of Borrower and Secured Parties and Guarantors by summary proceeding pursuant summary proceeding/collection rule or statute in the jurisdiction where enforcement is sought.
