(a) On or prior to each Filing Deadline, the Company shall prepare and file with the SEC a Registration Statement on Form S-1 or SB-2 (or, if the Company is then eligible, on Form S-3) covering the resale of all of the Registrable Securities. The Registration Statement prepared pursuant hereto shall register for resale at least the number of shares of Common Stock equal to the Required Registration Amount as of date the Registration Statement is initially filed with the SEC. The Registration Statement shall contain the “Selling Stockholders” and “Plan of Distribution” sections in substantially the form attached hereto as Exhibit A and contain all the required disclosures set forth on Exhibit B. The Company shall use its best efforts to have the Registration Statement declared effective by the SEC as soon as practicable, but in no event later than the Effectiveness Deadline. By 9:30 am on the date following the date of effectiveness, the Company shall file with the SEC in accordance with Rule 424 under the 1933 Act the final Prospectus to be used in connection with sales pursuant to such Registration Statement. The Company shall cause the Registration Statement to remain effective until all of the Registrable Securities have been sold or may be sold without volume restrictions pursuant to Rule 144(k), as determined by the counsel to the Company pursuant to a written opinion letter to such effect, addressed and acceptable to the Company’s transfer agent and the affected Holders (“Registration Period”). Prior to the filing of the Registration Statement with the SEC, the Company shall furnish a draft of the Registration Statement to the Buyers for their review and comment. The Buyers shall furnish comments on the Registration Statement to the Company within twenty-four (24) hours of the receipt thereof from the Company.

(b) Failure to File or Obtain Effectiveness of the Registration Statement. If: (i) a Registration Statement is not filed on or prior to its Filing Date (if the Company files a Registration Statement without affording the Holders the opportunity to review and comment on the same as required by Section 3(a), the Company shall not be deemed to have satisfied this clause (i)), or (ii) the Company fails to file with the SEC a request for acceleration in accordance with Rule 461 promulgated under the Securities Act, within five Trading Days of the date that the Company is notified (orally or in writing, whichever is earlier) by the SEC that a Registration Statement will not be “reviewed,” or not subject to further review, or (iii) a Registration Statement filed or required to be filed hereunder is not declared effective by the SEC by its Effectiveness Deadline, or (iv) after the effectiveness, a Registration Statement ceases for any reason to remain continuously effective as to all Registrable Securities for which it is required to be effective, or the Holders are otherwise not permitted to utilize the Prospectus therein to resell such Registrable Securities for more than 30 consecutive calendar days or more than an aggregate of 40 calendar days during any 12-month period (which need not be consecutive calendar days) (any such failure or breach being referred to as an “Event”), then in addition to any other rights the holders of the Convertible Debentures may have hereunder or under applicable law, on each such Event date and on each monthly anniversary of each such Event date (if the applicable Event shall not have been cured by such date) until the applicable Event is cured, the Company shall pay to each holder of Convertible Debentures an amount in cash, as partial liquidated damages (“Liquidated Damages”) and not as a penalty, equal to 2.0% of the aggregate purchase price paid by such holder pursuant to the Securities Purchase Agreement for any Convertible Debentures then held by such holder. The parties agree that (1) the Company shall not be liable for Liquidated Damages under this Agreement with respect to any Warrants or Warrant Shares and (2) the maximum aggregate Liquidated Damages payable to a holder of Convertible Debentures under this Agreement shall be twenty-four percent (24%) of the aggregate Purchase Price paid by such holder pursuant to the Securities Purchase Agreement. The partial Liquidated Damages pursuant to the terms hereof shall apply on a daily pro-rata basis for any portion of a month prior to the cure of an Event.

(c) Liquidated Damages. The Company and the Buyer hereto acknowledge and agree that the sums payable under subsection 2(b) above shall constitute liquidated damages and not penalties and are in addition to all other rights of the Buyer, including the right to call a default. The parties further acknowledge that (i) the amount of loss or damages likely to be incurred is incapable or is difficult to precisely estimate, (ii) the amounts specified in such subsections bear a reasonable relationship to, and are not plainly or grossly disproportionate to, the probable loss likely to be incurred in connection with any failure by the Company to obtain or maintain the effectiveness of a Registration Statement, (iii) one of the reasons for the Company and the Buyer reaching an agreement as to such amounts was the uncertainty and cost of litigation regarding the question of actual damages, and (iv) the Company and the Buyer are sophisticated business parties and have been represented by sophisticated and able legal counsel and negotiated this Agreement at arm’s length.

3. RELATED OBLIGATIONS.

(a) The Company shall, not less than three (3) Trading Days prior to the filing of each Registration Statement and not less than one (1) Trading Day prior to the filing of any related amendments and supplements to all Registration Statements (except for annual reports on Form 10-K or Form 10-KSB), furnish to each Buyer copies of all such documents proposed to be filed, which documents (other than those incorporated or deemed to be incorporated by reference) will be subject to the reasonable and prompt review of such Buyers, The Company shall not file a Registration Statement or any such Prospectus or any amendments or supplements thereto to which the Buyers shall reasonably object in good faith; provided that, the Company is notified of such objection in writing no later than two (2) Trading Days after the Buyers have been so furnished copies of a Registration Statement.

(b) The Company shall (i) prepare and file with the SEC such amendments (including post-effective amendments) and supplements to a Registration Statement and the Prospectus used in connection with such Registration Statement, which prospectus is to be filed pursuant to Rule 424 promulgated under the Securities Act, as may be necessary to keep such Registration Statement effective at all times during the Registration Period, and prepare and file with the SEC such additional Registration Statements in order to register for resale under the Securities Act all of the Registrable Securities; (ii) cause the related Prospectus to be amended or supplemented by any required Prospectus supplement (subject to the terms of this Agreement), and as so supplemented or amended to be filed pursuant to Rule 424; (iii) respond as promptly as reasonably possible to any comments received from the SEC with respect to a Registration Statement or any amendment thereto and as promptly as reasonably possible provide the Buyers true and complete copies of all correspondence from and to the SEC relating to a Registration Statement (provided that the Company may excise any information contained therein which would constitute material non-public information as to any Buyer which has not executed a confidentiality agreement with the Company); and (iv) comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities of the Company covered by such Registration Statement until such time as all of such Registrable Securities shall have been disposed of in accordance with the intended methods of disposition by the seller or sellers thereof as set forth in such Registration Statement. In the case of amendments and supplements to a Registration Statement which are required to be filed pursuant to this Agreement (including pursuant to this Section 3(b)) by reason of the Company’s filing a report on Form 10-KSB, Form 10-QSB or Form 8-K or any analogous report under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), the Company shall incorporate such report by reference into the Registration Statement, if applicable, or shall file such amendments or supplements with the SEC on the same day on which the Exchange Act report is filed which created the requirement for the Company to amend or supplement the Registration Statement.

(c) To the extent that the Buyer holds any Registrable Securities that are prohibited from being included on a the initial Registration Statement or any other Registration Statement (the “Non-Registered Shares”) under Rule 415, as interpreted by the SEC, then the Company shall become obligated to file an additional Registration Statement (each, a “Subsequent Registration Statement”) on the first day after such Subsequent Registration Statement may be filed without objection by the SEC under Rule 415 covering the resale by the Buyers of the maximum number of such Non-Registered Shares allowed under Rule 415 as interpreted by the SEC.

(d) The Company shall furnish to each Buyer whose Registrable Securities are included in any Registration Statement, without charge, (i) at least one (1) copy of such Registration Statement as declared effective by the SEC and any amendment(s) thereto, including financial statements and schedules, all documents incorporated therein by reference, all exhibits and each preliminary prospectus, (ii) ten (10) copies of the final prospectus included in such Registration Statement and all amendments and supplements thereto (or such other number of copies as such Buyer may reasonably request) and (iii) such other documents as such Buyer may reasonably request from time to time in order to facilitate the disposition of the Registrable Securities owned by such Buyer.

The Company shall promptly notify each Buyer who holds Registrable Securities of the receipt by the Company of any notification with respect to the suspension of the registration or qualification of any of the Registrable Securities for sale under the securities or “blue sky” laws of any jurisdiction in the United States or its receipt of actual notice of the initiation or threat of any proceeding for such purpose.

(f) As promptly as practicable after becoming aware of such event or development, the Company shall notify each Buyer in writing of the happening of any event as a result of which the Prospectus included in a Registration Statement, as then in effect, includes an untrue statement of a material fact or omission to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading (provided that in no event shall such notice contain any material, nonpublic information), and promptly prepare a supplement or amendment to such Registration Statement to correct such untrue statement or omission, and deliver ten (10) copies of such supplement or amendment to each Buyer. The Company shall also promptly notify each Buyer in writing (i) when a Prospectus or any Prospectus supplement or post-effective amendment has been filed, and when a Registration Statement or any post-effective amendment has become effective (notification of such effectiveness shall be delivered to each Buyer by facsimile on the same day of such effectiveness), (ii) of any request by the SEC for amendments or supplements to a Registration Statement or related prospectus or related information, and (iii) of the Company’s reasonable determination that a post-effective amendment to a Registration Statement would be appropriate.

(h) If, after the execution of this Agreement, a Buyer believes, after consultation with its legal counsel, that it could reasonably be deemed to be an underwriter of Registrable Securities, at the request of any Buyer, the Company shall furnish to such Buyer, on the date of the effectiveness of the Registration Statement and thereafter from time to time on such dates as a Buyer may reasonably request (i) a letter, dated such date, from the Company’s independent certified public accountants in form and substance as is customarily given by independent certified public accountants to underwriters in an underwritten public offering, and (ii) an opinion, dated as of such date, of counsel representing the Company for purposes of such Registration Statement, in form, scope and substance as is customarily given in an underwritten public offering, addressed to the Buyers.

Each Buyer agrees that it shall, upon learning that disclosure of such Records is sought in or by a court or governmental body of competent jurisdiction or through other means, give prompt notice to the Company and allow the Company, at its expense, to undertake appropriate action to prevent disclosure of, or to obtain a protective order for, the Records deemed confidential.

(k) The Company shall use its best efforts either to cause all the Registrable Securities covered by a Registration Statement (i) to be listed on each securities exchange on which securities of the same class or series issued by the Company are then listed, if any, if the listing of such Registrable Securities is then permitted under the rules of such exchange or (ii) the inclusion for quotation on the National Association of Securities Dealers, Inc. OTC Bulletin Board for such Registrable Securities. The Company shall pay all fees and expenses in connection with satisfying its obligation under this Section 3(j).

(l) The Company shall cooperate with each Buyer who holds Registrable Securities being offered and, to the extent applicable, to facilitate the timely preparation and delivery of certificates (not bearing any restrictive legend) representing the Registrable Securities to be offered pursuant to a Registration Statement and enable such certificates to be in such denominations or amounts, as the case may be, as the Buyers may reasonably request and registered in such names as the Buyers may request.

(n) The Company shall make generally available to its security holders as soon as practical, but not later than ninety (90) days after the close of the period covered thereby, an earnings statement (in form complying with the provisions of Rule 158 under the Securities Act) covering a twelve (12) month period beginning not later than the first day of the Company’s fiscal quarter next following the effective date of the Registration Statement.

(o) The Company shall otherwise use its best efforts to comply with all applicable rules and regulations of the SEC in connection with any registration hereunder.

Notwithstanding anything to the contrary, the Company shall cause its transfer agent to deliver unlegended certificates for shares of Common Stock to a transferee of a Buyer in accordance with the terms of the Securities Purchase Agreement in connection with any sale of Registrable Securities with respect to which a Buyer has entered into a contract for sale prior to the Buyer’s receipt of a notice from the Company of the happening of any event of the kind described in Section 3(f) or the first sentence of 3(e) and for which the Buyer has not yet settled.

With respect to Registrable Securities which are included in a Registration Statement under this Agreement:

(a) To the fullest extent permitted by law, the Company will, and hereby does, indemnify, hold harmless and defend each Buyer, the directors, officers, partners, employees, agents, representatives of, and each Person, if any, who controls any Buyer within the meaning of the Securities Act or the Exchange Act (each, an “Indemnified Person”), against any losses, claims, damages, liabilities, judgments, fines, penalties, charges, costs, reasonable attorneys’ fees, amounts paid in settlement or expenses, joint or several (collectively, “Claims”) incurred in investigating, preparing or defending any action, claim, suit, inquiry, proceeding, investigation or appeal taken from the foregoing by or before any court or governmental, administrative or other regulatory agency, body or the SEC, whether pending or threatened, whether or not an indemnified party is or may be a party thereto (“Indemnified Damages”), to which any of them may become subject insofar as such Claims (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon: (i) any untrue statement or alleged untrue statement of a material fact in a Registration Statement or any post-effective amendment thereto or in any filing made in connection with the qualification of the offering under the securities or other “blue sky” laws of any jurisdiction in which Registrable Securities are offered (“Blue Sky Filing”), or the omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading; (ii) any untrue statement or alleged untrue statement of a material fact contained in any final prospectus (as amended or supplemented, if the Company files any amendment thereof or supplement thereto with the SEC) or the omission or alleged omission to state therein any material fact necessary to make the statements made therein, in light of the circumstances under which the statements therein were made, not misleading; or (iii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any other law, including, without limitation, any state securities law, or any rule or regulation there under relating to the offer or sale of the Registrable Securities pursuant to a Registration Statement (the matters in the foregoing clauses (i) through (iii) being, collectively, “Violations”). The Company shall reimburse the Buyers and each such controlling person promptly as such expenses are incurred and are due and payable, for any legal fees or disbursements or other reasonable expenses incurred by them in connection with investigating or defending any such Claim. Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 6(a): (x) shall not apply to a Claim by an Indemnified Person arising out of or based upon a Violation which occurs in reliance upon and in conformity with information furnished in writing to the Company by such Indemnified Person expressly for use in connection with the preparation of the Registration Statement or any such amendment thereof or supplement thereto; (y) shall not be available to the extent such Claim is based on a failure of the Buyer to deliver or to cause to be delivered the prospectus made available by the Company, if such prospectus was timely made available by the Company pursuant to Section 3(c); and (z) shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of the Company, which consent shall not be unreasonably withheld. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Indemnified Person and shall survive the transfer of the Registrable Securities by the Buyers pursuant to Section 9 hereof.

(b) In connection with a Registration Statement, each Buyer agrees to severally and not jointly indemnify, hold harmless and defend, to the same extent and in the same manner as is set forth in Section 6(a), the Company, each of its directors, each of its officers, employees, representatives, or agents and each Person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act (each an “Indemnified Party”), against any Claim or Indemnified Damages to which any of them may become subject, under the Securities Act, the Exchange Act or otherwise, insofar as such Claim or Indemnified Damages arise out of or is based upon any Violation, in each case to the extent, and only to the extent, that such Violation occurs in reliance upon and in conformity with written information furnished to the Company by such Buyer expressly for use in connection with such Registration Statement; and, subject to Section 6(d), such Buyer will reimburse any legal or other expenses reasonably incurred by them in connection with investigating or defending any such Claim; provided, however, that the indemnity agreement contained in this Section 6(b) and the agreement with respect to contribution contained in Section 7 shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of such Buyer, which consent shall not be unreasonably withheld; provided, further, however, that the Buyer shall be liable under this Section 6(b) for only that amount of a Claim or Indemnified Damages as does not exceed the net proceeds to such Buyer as a result of the sale of Registrable Securities pursuant to such Registration Statement. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Indemnified Party and shall survive the transfer of the Registrable Securities by the Buyers pursuant to Section 9. Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 6(b) with respect to any prospectus shall not inure to the benefit of any Indemnified Party if the untrue statement or omission of material fact contained in the prospectus was corrected and such new prospectus was delivered to each Buyer prior to such Buyer’s use of the prospectus to which the Claim relates.

(c) Promptly after receipt by an Indemnified Person or Indemnified Party under this Section 6 of notice of the commencement of any action or proceeding (including any governmental action or proceeding) involving a Claim, such Indemnified Person or Indemnified Party shall, if a Claim in respect thereof is to be made against any indemnifying party under this Section 6, deliver to the indemnifying party a written notice of the commencement thereof, and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume control of the defense thereof with counsel mutually satisfactory to the indemnifying party and the Indemnified Person or the Indemnified Party, as the case may be; provided, however, that an Indemnified Person or Indemnified Party shall have the right to retain its own counsel with the fees and expenses of not more than one (1) counsel for such Indemnified Person or Indemnified Party to be paid by the indemnifying party, if, in the reasonable opinion of counsel retained by the indemnifying party, the representation by such counsel of the Indemnified Person or Indemnified Party and the indemnifying party would be inappropriate due to actual or potential differing interests between such Indemnified Person or Indemnified Party and any other party represented by such counsel in such proceeding. The Indemnified Party or Indemnified Person shall cooperate fully with the indemnifying party in connection with any negotiation or defense of any such action or claim by the indemnifying party and shall furnish to the indemnifying party all information reasonably available to the Indemnified Party or Indemnified Person which relates to such action or claim. The indemnifying party shall keep the Indemnified Party or Indemnified Person fully apprised at all times as to the status of the defense or any settlement negotiations with respect thereto. No indemnifying party shall be liable for any settlement of any action, claim or proceeding effected without its prior written consent; provided, however, that the indemnifying party shall not unreasonably withhold, delay or condition its consent. No indemnifying party shall, without the prior written consent of the Indemnified Party or Indemnified Person, consent to entry of any judgment or enter into any settlement or other compromise which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party or Indemnified Person of a release from all liability in respect to such claim or litigation. Following indemnification as provided for hereunder, the indemnifying party shall be subrogated to all rights of the Indemnified Party or Indemnified Person with respect to all third parties, firms or corporations relating to the matter for which indemnification has been made. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action shall not relieve such indemnifying party of any liability to the Indemnified Person or Indemnified Party under this Section 6, except to the extent that the indemnifying party is prejudiced in its ability to defend such action.

(d) The indemnification required by this Section 6 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or Indemnified Damages are incurred.

(e) The indemnity agreements contained herein shall be in addition to (i) any cause of action or similar right of the Indemnified Party or Indemnified Person against the indemnifying party or others, and (ii) any liabilities the indemnifying party may be subject to pursuant to the law.

7. CONTRIBUTION.

To the extent any indemnification by an indemnifying party is prohibited or limited by law, the indemnifying party agrees to make the maximum contribution with respect to any amounts for which it would otherwise be liable under Section 6 to the fullest extent permitted by law; provided, however, that: (i) no seller of Registrable Securities guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any seller of Registrable Securities who was not guilty of fraudulent misrepresentation; and (ii) contribution by any seller of Registrable Securities shall be limited in amount to the net amount of proceeds received by such seller from the sale of such Registrable Securities.

8. REPORTS UNDER THE EXCHANGE ACT.

With a view to making available to the Buyers the benefits of Rule 144 promulgated under the Securities Act or any similar rule or regulation of the SEC that may at any time permit the Buyers to sell securities of the Company to the public without registration (“Rule 144”) the Company agrees to:

(a) make and keep public information available, as those terms are understood and defined in Rule 144;

(b) file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act so long as the Company remains subject to such requirements (it being understood that nothing herein shall limit the Company’s obligations under Section 4(c) of the Securities Purchase Agreement) and the filing of such reports and other documents as are required by the applicable provisions of Rule 144; and

(c) furnish to each Buyer so long as such Buyer owns Registrable Securities, promptly upon request, (i) a written statement by the Company that it has complied with the reporting requirements of Rule 144, the Securities Act and the Exchange Act, (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company, and (iii) such other information as may be reasonably requested to permit the Buyers to sell such securities pursuant to Rule 144 without registration.

9. AMENDMENT OF REGISTRATION RIGHTS.

Provisions of this Agreement may be amended and the observance thereof may be waived (either generally or in a particular instance and either retroactively or prospectively), only with the written consent of the Company and Buyers who then hold at least two-thirds (2/3) of the Registrable Securities. Any amendment or waiver effected in accordance with this Section 9 shall be binding upon each Buyer and the Company. No such amendment shall be effective to the extent that it applies to fewer than all of the holders of the Registrable Securities. No consideration shall be offered or paid to any Person to amend or consent to a waiver or modification of any provision of any of this Agreement unless the same consideration also is offered to all of the parties to this Agreement.

10. MISCELLANEOUS.

(a) A Person is deemed to be a holder of Registrable Securities whenever such Person owns or is deemed to own of record such Registrable Securities or owns the right to receive the Registrable Securities. If the Company receives conflicting instructions, notices or elections from two (2) or more Persons with respect to the same Registrable Securities, the Company shall act upon the basis of instructions, notice or election received from the registered owner of such Registrable Securities.

(b) No Piggyback on Registrations. Except as set forth on Schedule 10(b) attached hereto, neither the Company nor any of its security holders (other than the Buyers in such capacity pursuant hereto) may include securities of the Company in the initial Registration Statement other than the Registrable Securities.

(c) Piggy-Back Registrations. If at any time during the Registration Period there is not an effective Registration Statement covering all of the Registrable Securities and the Company shall determine to prepare and file with the SEC a registration statement relating to an offering for its own account or the account of others under the Securities Act of any of its equity securities, other than on Form S-4 or Form S-8 (each as promulgated under the Securities Act) or their then equivalents relating to equity securities to be issued solely in connection with any acquisition of any entity or business or equity securities issuable in connection with the stock option or other employee benefit plans, then the Company shall send to each Buyer a written notice of such determination and, if within fifteen (15) days after the date of such notice, any such Buyer shall so request in writing, the Company shall include in such registration statement all or any part of such Registrable Securities such Buyer requests to be registered; provided, however, that, the Company shall not be required to register any Registrable Securities pursuant to this Section 10(c) that are eligible for resale pursuant to Rule 144(k) promulgated under the Securities Act or that are the subject of a then effective Registration Statement.

(d) Any notices, consents, waivers or other communications required or permitted to be given under the terms of this Agreement must be in writing and will be deemed to have been delivered: (i) upon receipt, when delivered personally; (ii) upon receipt, when sent by facsimile (provided confirmation of transmission is mechanically or electronically generated and kept on file by the sending party); or (iii) one (1) business day after deposit with a nationally recognized overnight delivery service, in each case properly addressed to the party to receive the same.

EXHIBIT A

SELLING STOCKHOLDERS

AND PLAN OF DISTRIBUTION

Selling Stockholders

The shares of Common Stock being offered by the selling stockholders are issuable upon conversion of the convertible debentures and upon exercise of the warrants. For additional information regarding the issuance of those convertible notes and warrants, see “Private Placement of Convertible Debentures and Warrants” above. We are registering the shares of Common Stock in order to permit the selling stockholders to offer the shares for resale from time to time. Except as otherwise notes and except for the ownership of the convertible Debentures and the warrants issued pursuant to the Securities Purchase Agreement, the selling stockholders have not had any material relationship with us within the past three years.

The table below lists the selling stockholders and other information regarding the beneficial ownership of the shares of Common Stock by each of the selling stockholders. The second column lists the number of shares of Common Stock beneficially owned by each selling stockholder, based on its ownership of the convertible debentures and warrants, as of ________, 200_, assuming conversion of all convertible debentures and exercise of the warrants held by the selling stockholders on that date, without regard to any limitations on conversions or exercise.

The third column lists the shares of Common Stock being offered by this prospectus by the selling stockholders.

In accordance with the terms of a registration rights agreement with the selling stockholders, this prospectus generally covers the resale of at least (i) 300% of the number of Conversion Shares issued and issuable pursuant to the convertible debentures as of the trading day immediately preceding the date the registration statement is initially filed with the SEC, and (ii) 100% of the number of warrant shares issued and issuable pursuant to the warrants as of the trading day immediately preceding the date the registration statement is initially filed with the SEC. Because the conversion price of the convertible debentures and the exercise price of the warrants may be adjusted, the number of shares that will actually be issued may be more or less than the number of shares being offered by this prospectus. The fourth column assumes the sale of all of the shares offered by the selling stockholders pursuant to this prospectus.

Under the terms of the convertible debentures and the warrants, a selling stockholder may not convert the convertible debentures or exercise the warrants to the extent such conversion or exercise would cause such selling stockholder, together with its affiliates, to beneficially own a number of shares of Common Stock which would exceed 4.99% of our then outstanding shares of Common Stock following such conversion or exercise, excluding for purposes of such determination shares of Common Stock issuable upon conversion of the convertible debentures which have not been converted and upon exercise of the warrants which have not been exercised. The number of shares in the second column does not reflect this limitation. The selling stockholders may sell all, some or none of their shares in this offering. See "Plan of Distribution."

(1) Cornell Capital Partners, L.P. is a Cayman Island exempt limited partnership. Cornell is managed by Yorkville Advisors, LLC. Investment decisions for Yorkville Advisors are made by Xxxx Xxxxxx, its portfolio manager.

Plan of Distribution

Each Selling Stockholder (the “Selling Stockholders”) of the common stock and any of their pledgees, assignees and successors-in-interest may, from time to time, sell any or all of their shares of common stock on the __________ or any other stock exchange, market or trading facility on which the shares are traded or in private transactions. These sales may be at fixed or negotiated prices. A Selling Stockholder may use any one or more of the following methods when selling shares:

·	ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

·	block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;

·	purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

·	an exchange distribution in accordance with the rules of the applicable exchange;

·	privately negotiated transactions;

·	broker-dealers may agree with the Selling Stockholders to sell a specified number of such shares at a stipulated price per share;

·	through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

·	a combination of any such methods of sale; or

·	any other method permitted pursuant to applicable law.

The Selling Stockholders may also sell shares under Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”), if available, rather than under this prospectus.

Broker-dealers engaged by the Selling Stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the Selling Stockholders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this Prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with NASDR Rule 2440; and in the case of a principal transaction a markup or markdown in compliance with NASDR IM-2440.

In connection with the sale of the common stock or interests therein, the Selling Stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the Common Stock in the course of hedging the positions they assume. The Selling Stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The Selling Stockholders and any broker-dealers or agents that are involved in selling the shares may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Each Selling Stockholder has informed the Company that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the Common Stock. In no event shall any broker-dealer receive fees, commissions and markups which, in the aggregate, would exceed eight percent (8%).

The Company is required to pay certain fees and expenses incurred by the Company incident to the registration of the shares. The Company has agreed to indemnify the Selling Stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

Because Selling Stockholders may be deemed to be “underwriters” within the meaning of the Securities Act, they will be subject to the prospectus delivery requirements of the Securities Act including Rule 172 thereunder. In addition, any securities covered by this prospectus which qualify for sale pursuant to Rule 144 under the Securities Act may be sold under Rule 144 rather than under this prospectus. There is no underwriter or coordinating broker acting in connection with the proposed sale of the resale shares by the Selling Stockholders.

We agreed to keep this prospectus effective until the earlier of (i) the date on which the shares may be resold by the Selling Stockholders without registration and without regard to any volume limitations by reason of Rule 144(k) under the Securities Act or any other rule of similar effect or (ii) all of the shares have been sold pursuant to this prospectus or Rule 144 under the Securities Act or any other rule of similar effect. The resale shares will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale shares may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale shares may not simultaneously engage in market making activities with respect to the common stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the Selling Stockholders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of shares of the common stock by the Selling Stockholders or any other person. We will make copies of this prospectus available to the Selling Stockholders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

Pursuant to the Purchase Agreement, the Company also has entered into a Registration Rights Agreement with the Buyers (the “Registration Rights Agreement”) pursuant to which the Company agreed, among other things, to register the Registrable Securities (as defined in the Registration Rights Agreement) under the Securities Act of 1933, as amended (the “Securities Act”). In connection with the Company’s obligations under the Registration Rights Agreement, on ____________ ____, the Company filed a Registration Statement on Form ________ (File No. 333-_____________) (the “Registration Statement”) with the Securities and Exchange Commission (the “SEC”) relating to the Registrable Securities which names each of the Buyers as a selling stockholder there under.

In connection with the foregoing, we advise you that a member of the SEC’s staff has advised us by telephone that the SEC has entered an order declaring the Registration Statement effective under the Securities Act at [ENTER TIME OF EFFECTIVENESS] on [ENTER DATE OF EFFECTIVENESS] and we have no knowledge, after telephonic inquiry of a member of the SEC’s staff, that any stop order suspending its effectiveness has been issued or that any proceedings for that purpose are pending before, or threatened by, the SEC and the Registrable Securities are available for resale under the Securities Act pursuant to the Registration Statement.

	Very truly yours,

	[Law Firm]
