2.             REGISTRATION.

a.  MANDATORY REGISTRATION. Following the Closing of any Preferred Stock pursuant to the Purchase Agreement, the Company shall use its best efforts to promptly prepare and file with the SEC as soon as practicable, but in no event later than the Filing Deadline (as defined above) a Registration Statement on Form SB-2 (or, if Form SB-2 is not then available, on such form of Registration Statement as is then available to effect a registration of all of the Registrable Securities, subject to the consent of the Buyer, which consent will not be unreasonably withheld) covering the resale of the Registrable Securities which Registration Statement, to the extent allowable under the 1933 Act and the rules and regulations promulgated thereunder (including Rule 416), shall state that such Registration Statement also covers such indeterminate number of additional shares of Common Stock as may become issuable upon conversion of the Preferred Stock or otherwise pursuant to the Certificate of Designation and exercise of or otherwise pursuant to the

2

Warrants to prevent dilution resulting from stock splits, stock dividends or similar transactions. The number of shares of Common Stock initially included in such Registration Statement shall be no less than one and one-half (1.5) times the aggregate number of Conversion Shares that are then issuable upon conversion of the Preferred Stock or otherwise pursuant to the Certificate of Designation (based on the Conversion Price as defined in the Certificate of Designation then in effect) plus the aggregate number of Warrant Shares that are then issuable upon exercise of or otherwise pursuant to the Warrants, without regard to any limitation on the Buyer’s ability to convert the Preferred Stock or exercise the Warrants (collectively, the “Target Registration Amount”).  Notwithstanding the foregoing, if the Company is advised by the staff of the SEC in a written comment letter that it is not eligib le to conduct the offering of the Preferred Stock under Rule 415 promulgated under the 1933 Act because of the number of shares sought to be included in the Registration Statement, then the Company may reduce (an “SEC Share Reduction”) the number of shares covered by such Registration Statement to the maximum number which would enable the Company to conduct such offering in accordance with the provisions of Rule 415 (“Rule 415 Eligible”), provided that in no event shall the number of shares covered by such Registration Statement be reduced to a number less than thirty-three percent (33%) (or such lower percentage of the Company’s Public Float as may be required, in writing, in correspondence from the SEC staff to the Company or in a telephone conversation with the SEC staff which includes a representative of the Lead Investor) of the Company’s Public Float (as defined below), on the actual filing date of the subject Registration Statement, where “PUBLIC FLOAT” shall me an the number of shares of Common Stock of the Company that are outstanding, excluding shares held by Affiliates, where “AFFILIATES” shall mean directors, officers and holders of 10% or greater of the outstanding Common Stock of the Company.  In such event, any reduction in Registrable Securities covered by the Registration Statement shall be effected on a pro rata basis among all holders of the Registrable Securities.  In the event that, due to an SEC Share Reduction or otherwise, the initial Registration Statement shall register a number of shares of Common Stock which is less than the Target Registration Amount (an “Initial Target Registration Shortfall”), the unregistered portion of the Target Registration Amount (the “Initial Target Registration Shortfall Amount”) shall be included in the next Follow-On Registration (in accordance with Section 3(b) below). The Company acknowledges that the number of shares initially included in each Registration Statement represen ts a good faith estimate of the maximum number of shares issuable upon conversion of the Preferred Stock or otherwise pursuant to the Certificate of Designation and exercise of or otherwise pursuant to the Warrants and shall be amended if not sufficient.  Each Registration Statement (and each amendment or supplement thereto, and each request for acceleration of effectiveness thereof) shall be provided to (and subject to the approval of) the Buyer and its counsel prior to its filing or other submission.

b.  PIGGY-BACK REGISTRATIONS.  If at any time prior to the expiration of the Registration Period (as hereinafter defined) the Company shall file with the SEC a Registration Statement relating to an offering for its own account or the account of others under the 1933 Act of any of its equity secu rities (other than on Form S-4 or Form S-8 or their 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 stock option or other employee benefit plans), the Company shall send to Buyer written notice of such determination and, if within fifteen (15) days after the effective date of such notice, the Buyer shall so request in writing, the Company shall include in such Registration Statement all or any part of the Registrable Securities the Buyer requests to be registered, except that if, (i) inclusion of such shares would result in the offering not being Rule 415 Eligible, or (ii) in connection with any underwritten public offering for the account of the Company, the managing underwriter(s) thereof shall impose a limitation on the number of shares of Common Stock which may be included in the Registration Statement because, in such

3

underwriter(s)’ judgment, marketing or other factors dictate such limitation is necessary to facilitate public distribution, then the Company shall be obligated to include in such Registration Statement only such limited portion of the Registrable Securities with respect to which the Buyer has requested inclusion hereunder (i) as would enable the offering to be Rule 415 Eligible or (ii) as the underwriter shall permit;

PROVIDED, HOWEVER, that the Company shall not exclude any Registrable Securities unless the Company has first excluded all outstanding securities, the holders of which are not entitled by contract to inclusion of such securities in such Registration Statement or are not entitled to pro rata i nclusion with the Registrable Securities; and

PROVIDED, FURTHER, HOWEVER, that, after giving effect to the immediately preceding proviso, any exclusion of Registrable Securities shall be made pro rata with holders of other securities having the contractual right to include such securities in the Registration Statement other than holders of securities entitled to inclusion of their securities in such Registration Statement by reason of demand registration rights. No right to registration of Registrable Securities under this Section 2(b) shall be construed to limit any registration required under Section 2(a) hereof.  If an offering in connection with which the Buyer is entitled to registration under this Section 2(b) is an underwritten offering, then the Buyer shall, unless otherwise agreed by the Compan y, offer and sell such Registrable Securities in an underwritten offering using the same underwriter or underwriters and, subject to the provisions of this Agreement, on the same terms and conditions as other shares of Common Stock included in such underwritten offering. Notwithstanding anything to the contrary set forth herein, the registration rights of the Buyer pursuant to this Section 2(b) shall only be available in the event the Company fails to timely file, obtain effectiveness or maintain effectiveness of any Registration Statement to be filed pursuant to Section 2(a) in accordance with the terms of this Agreement.

3.  OBLIGATIONS OF THE COMPANY.  In connection with the registration of the Registrable Securities, the Company shall have the following obligations:

a.  The Company shall prepare promptly, and file with the SEC as soon as practicable after the date of the Closing under the Purchase Agreement (the “CLOSING DATE”) (but no later than the Filing Deadline), Registration Statements with respect to the number of Registrable Securities provided in Section 2(a), and thereafter use its best efforts to cause each such Registration Statement relating to Registrable Securities to become effective as soon as possible after such filing, but in any event shall cause each such Registration Statement relating to Registrable Securities to become effective no later than the Registration Deadline, and shall keep the Registration Statement current and effective pursuant to Rule 415 at all times until such date as is the earlier of (i) the date on which all of the Registrable Securities for such Registration Statement have been sold and (ii) the date on which all o f the Registrable Securities for such Registration Statement (in the opinion of counsel to the Buyer) may be immediately sold to the public without registration or restriction (including without limitation as to volume by each holder thereof) under the 1933 Act (the “REGISTRATION PERIOD”), which Registration Statement (including any amendments or supplements thereto and prospectuses contained therein) shall not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein, or necessary to make the statements therein not misleading.

b.  The Company shall prepare and file with the SEC such amendments (including post-effective amendments) and supplements to each Registration Statement and the prospectus used in

4

connection with the Registration Statements as may be necessary to keep the Registration Statements current and effective at all times during the Registration Period, and, during such period, comply with the provisions of the 1933 Act with respect to the disposition of all Registrable Securities of the Company covered by the Registration Statements until such time as all of such Registrable Securities have been disposed of in accordance with the intended methods of disposition by the seller or sellers thereof as set forth in the Registration Statements. In the event of an Initial Target Registration Shortfall, or in the event that on any Trading Day (as defined in the Certificate of Designation) (the “REGISTRATION TRIGGER DATE”) the number of shares available under a Registration Statement filed pursuant to this Agreement is insufficient to cover all of the Registrable Securities issued or issuable upo n conversion of the Preferred Stock or otherwise pursuant to the Certificate of Designation (based on the Conversion Price as defined in the Certificate of Designation then in effect), exercise of or otherwise pursuant to the Warrants, and otherwise issuable pursuant to the Transaction Documents, in each case without giving effect to any limitations on the Buyer’ ability to convert the Preferred Stock, exercise the Warrants or otherwise receive shares of Common Stock pursuant to the Transaction Documents, the Company shall amend the Registration Statement, or file a new Registration Statement (on the short form available therefore, if applicable), or both (each, a “Follow-On Registration Statement”), so as to cover one and one-half (1.5) times the total number of Registrable Securities so issued or issuable (without giving effect to any limitations on conversion contained in the Certificate of Designation, limitations on exercise contained in the Warrants or limitations on conversion or exerci se or other payment of shares contained in the Purchase Agreement) as of the Registration Trigger Date (subject to an SEC Share Reduction, if applicable), in each case, as soon as practicable, but in any event within twenty (20) days after the Registration Trigger Date (based on the Conversion Prices of the Preferred Stock, the Exercise Prices of the Warrants, and other relevant factors on which the Company reasonably elects to rely). The Company shall use its best efforts to cause such amendment and/or new Registration Statement to become effective as soon as practicable following the filing thereof, but in any event the Company shall cause such amendment and/or new Registration Statement to become effective within ninety (90) days of the Registration Trigger Date or as promptly as practicable in the event the Company is required to increase its authorized shares.  Each Follow-On Registration Statement shall be filed as soon as practicable, but in any event, subject to compliance with then applicable S EC policy (as confirmed in writing, in correspondence from the SEC staff to the Company or in a telephone conversation with the SEC staff which includes a representative of the Lead Investor), not later than the date that is five (5) Business Days after the later of (A) the date that is six (6) calendar months following the date of effectiveness of the most recently effective Registration Statement or Follow-On Registration Statement filed hereunder, and (B) the date that is sixty (60) days following the date that “substantially all” (where “substantially all” shall mean 75% unless then interpreted otherwise by the SEC, in a writing directed to the Company) of the then registered Registrable Securities have been sold.

c.  The Company shall furnish to the Buyer and its legal counsel (i) promptly after the same is prepared and publicly distributed, filed with t he SEC, or received by the Company, one copy of each Registration Statement and any amendment thereto, each preliminary prospectus and prospectus and each amendment or supplement thereto, and, in the case of the Registration Statement referred to in Section 2(a), each letter written by or on behalf of the Company to the SEC or the staff of the SEC, and each item of correspondence from the SEC or the staff of the SEC, in each case relating to such Registration Statement (other than any portion of any thereof which contains information for which the Company has sought confidential treatment), and (ii) such number of copies of a prospectus, including a preliminary prospectus, and all amendments and supplements thereto and such other documents as the Buyer may reasonably request in order to

5

facilitate the disposition of the Registrable Securities owned by the Buyer. The Company will immediately notify the Buyer by facsimile of the effectiveness of each Registration Statement or any post-effective amendment. The Company will promptly respond to any and all comments received from the SEC, with a view towards causing each Registration Statement or any amendment thereto to be declared effective by the SEC as soon as practicable and shall file an acceleration request as soon as practicable, but no later than three (3) business days (the “ACCELERATION REQUEST DEADLINE”), following the resolution or clearance of all SEC comments or, if applicable, following notification by the SEC that any such Registration Statement or any amendment thereto will not be subject to review.

d.  The Company shall use reasonable efforts to (i) register and qualify the Registrable Securities covered by the Registration Statements under such other securities or “blue sky” laws of such jurisdictions in the United States as the Buyer shall reasonably request, (ii) prepare and file in those jurisdictions such amendments (including post-effective amendments) and supplements to such registrations and qualifications as may be necessary to maintain the effectiveness thereof during the Registration Period, (iii) take such other actions as may be necessary to maintain such registrations and qualifications in effect at all times during the Registration Period, and (iv) take all other actions reasonably necessary or advisable to qualify the Registrable Securities for sale in such jurisdictions;

e.  As promptly as practicable after becoming aware of such event, th e Company shall notify the Buyer of the happening of any event, of which the Company has knowledge, as a result of which the prospectus included in any Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and use its best efforts promptly to prepare a supplement or amendment to any Registration Statement to correct such untrue statement or omission, and deliver such number of copies of such supplement or amendment to the Buyer as the Buyer may reasonably request; provided that, for not more than twenty (20) consecutive days (or a total of not more than sixty (60) days in any twelve (12) month period), the Company may delay the disclosure of material non-public information concerning the Company (as well as prospectus or Registration Statement updating) the disclosure of which at the time is not, in the good faith opinion of the Company, in the best interests of the Company (an “ALLOWED DELAY”); provided, further, that the Company shall promptly (i) notify the Buyer in writing of the existence of (but in no event, without the prior written consent of the Buyer, shall the Company disclose to the Buyer any of the facts or circumstances regarding) material non-public information giving rise to an Allowed Delay and (ii) advise the Buyer in writing to cease all sales under such Registration Statement until the end of the Allowed Delay, provided the above actions are consistent with the requirements of the 1933 Act and/or the Securities Exchange Act of 1934, as amended (the “1934 ACT”) or other applicable law. Upon expiration of the Allowed Delay, the Company shall again be bound by the first sentence of this Section 3(e) with respect to the information giving rise thereto.  Nothing herein relieves the obligations set forth in the Certificate of Designation or the Warrants relative to Failure Payments or payments of the Default Amount pursuant to Events of Default.

f.  The Company shall use commercially reasonable efforts to prevent the issuance of any stop order or other suspension of effectiveness of any Registration Statement, and, if such an order is issued, to obtain the withdrawal of such order at the earliest possible moment and to notify the Buyer who holds Registrable Securities being sold (or, in the event of an underwritten offering, the managing underwriters) of the issuance of such order and the resolution thereof.

6

g.  The Company shall permit a single firm of counsel designated by the Buyer to review such Registration Statement and all amendments and supplements thereto (as well as all requests for acceleration or effectiveness thereof), at Buyer’s own cost, a reasonable period of time prior to their filing with the SEC (not less than three (3) business days but not more than five (5) business days) and not file any document in a form to which such counsel reasonably objects and will not request acceleration of such Registration Statement without prior notice to such counsel.

h.  The Company shall hold in confidence and not make any disclosure of information concerning the Buyer provided to the Company unless (i) disclosure of such information is necessary to comp ly with federal or state securities laws, (ii) the disclosure of such information is necessary to avoid or correct a misstatement or omission in any Registration Statement, (iii) the release of such information is ordered pursuant to a subpoena or other order from a court or governmental body of competent jurisdiction, (iv) such information has been made generally available to the public other than by disclosure in violation of this or any other agreement, or (v) Buyer consents to such disclosure, in writing. The Company agrees that it shall, upon learning that disclosure of such information concerning the Buyer is sought in or by a court or governmental body of competent jurisdiction or through other means, give prompt notice to the Buyer prior to making such disclosure, and allow the Buyer, at its expense, to undertake appropriate action to prevent disclosure of, or to obtain a protective order for, such information.

i.  The Company shall use commercially reasonable efforts to cause all the Registrable Securities covered by the Registration Statement to be quoted on the OTC Bulletin Board.  If the Company becomes listed on a national securities exchange, it shall cause all the Registrable Securities covered by the Registration Statement to be listed on each national 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, and, without limiting the generality of the foregoing, to arrange for at least two market makers to register with the National Association of Securities Dealers, Inc. (“NASD”) as such with respect to such Registrable Securities.

j.  The Company shall provide a tran sfer agent and registrar, which may be a single entity, for the Registrable Securities not later than the effective date of the Registration Statement.

k.  The Company shall cooperate with the Buyer who holds Registrable Securities being offered and the managing underwriter or underwriters, if any, to facilitate the timely preparation and delivery of certificates (not bearing any restrictive legends) representing Registrable Securities to be offered pursuant to such Registration Statement and enable such certificates to be in such denominations or amounts, as the case may be, as the managing underwriter or underwriters, if any, or the Buyer may reasonably request and registered in such names as the managing underwriter or underwriters, if any, or the Buyer may request, and, within five (5) business days after a Registration Statement which includes Registrable Securities is orde red effective by the SEC, the Company shall deliver, and shall cause legal counsel selected by the Company to deliver, to the transfer agent for the Registrable Securities (with copies to the Buyer) an appropriate instruction and an opinion of such counsel in the form required by the transfer agent in order to issue the Registrable Securities free of restrictive legends.

l.  At the request of the holders of a majority-in-interest of the Registrable Securities, the Company shall prepare and file with the SEC such amendments (including post-effective amendments) and supplements to a Registration Statement and any prospectus used in connection

7

with the Registration Statement as may be necessary in order to change the plan of distribution set forth in such Registration Statement.

m.  The Company shall not, and shall not agree to, allow the holders of any securities of the Company to include any of their securities in any Registration Statement under Section 2(a) hereof or any amendment or supplement thereto under Section 3(b) hereof without the consent of the holders of a majority-in-interest of the Registrable Securities, except for securities which have contractual piggyback registration rights in effect at the time of the Initial Closing (as defined in the Purchase Agreement). In addition, the Company shall not offer any securities for its own account or the account of others in any Registration Statement under Section 2(a) hereof or any amendment or supplement thereto under Section 3(b) hereof without the consent of the holders of a majority-in-interest of the Registrable Securities.

n.  The Company shall take all other reasonable actions necessary to expedite and facilitate disposition by the Buyer of Registrable Securities pursuant to a Registration Statement.

The Exclusion Period will be tolled during the pendency of an Event of Default as defined in the Certificate of Designation or an Event of Default as defined in the Warrants.

q.  NASD Rule 2710 Filing; Broker Compensation.  If required by the National Association of Securities Dealers, Inc. (“NASD”) Corporate Financing Department, the Company shall promptly effect a filing with the NASD pursuant to NASD Rule 2710 with respect to the public offering contemplated by resales of securities under the Registration Statement (an “ISSUER FILING”), and pay the filing fee required by such Issuer Filing.  The Company shall use commercially reasonable efforts to pursue the Issuer Filing until the NASD issues a letter confirming that it does not object to the terms of the offering contemplated by the Registration Statement.

b.  In connection with any Registration Statement in which a Buyer is participating, each such Buyer agrees severally, and not jointly, to indemnify, hold harmless and defend, to the same extent and in the same manner set forth in Section 6(a), the Company, each of its directors, each of its officers who signs the Registration Statement, its employees, agents and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, and any other stockholder selling securities pursuant to the Registration Statement or any of its directors or officers or any person who controls such stockholder within the meaning of the 1933 Act or the 1934 Act (collectively and together with an Indemnified Person, an “INDEMNIFIED PARTY”), against any Claim to which any of them may become subject, under the 1933 Act, the 1934 Act or otherwise, insofar as such Claim arises out of or is based upon any statement or alleged statement in or omission or alleged omission from such registration statement, any preliminary, final or summary prospectus contained therein, or any amendment or supplement, in each case to the extent (and only to the extent) that such statement or alleged statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by the Buyer for use in the preparation of such registration statement, preliminary, final or summary prospectus or amendment or supplement, or a document incorporated by reference into any of the foregoing (a “BUYER VIOLATION”); and subject to Section 6 (c) such Buyer will reimburse any legal or other expenses (promptly as such expenses are incurred and are due and payable) 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) 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 Agreement (including this Section 6(b)) for only that amount as does not exceed the net proceeds actually received by 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 Buyer.  Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 6(b) with respect to any preliminary prospectus shall not inure to the benefit of any Indemnified Party if the untrue statement or omission of material fact contained in the preliminary prospectus was corrected on a timely basis in the prospectus, as then amended or supplemented.

c.  Promptly after receipt by an Indemnified Person under this Section 6 of notice of the commencement of any action (including any governmental action), such Indemnified Person shall, if a Claim in respect thereof is to be made against any the Company under this Section 6, deliver to the Company a written notice of the commencement thereof, and the Company shall have the right to participate in, and, to the extent the Company so desires, to assume control of the defense thereof with counsel mutually satisfactory to the Company and the Indemnified Person, as the case may be.

PROVIDED, HOWEVER, that an Indemnified Person shall have the right to retain its own counsel with the fees and expenses to be paid by the C ompany, if, in the reasonable opinion of counsel retained by the Company, the representation by such counsel of the Indemnified Person and the Company would be inappropriate due to actual or potential differing interests between such Indemnified Person and any other party represented by such counsel in such proceeding. The Company shall pay for only one separate legal counsel for the Indemnified Persons, and such legal counsel shall be selected by Buyer, if the Buyer is entitled to indemnification hereunder.  The failure to deliver written notice to the Company within a reasonable time of the commencement of any such action shall not relieve the Company of any liability to the Indemnified Person under this Section 6,

11

except to the extent that the Company is actually prejudiced in its ability to defend such action. 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 such expense, loss, damage or liability is incurred and is due and payable.

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, based upon a comparative fault standard; provided, however, that (i) no person gu ilty of fraudulent misrepresentation (within the meaning of Section 12(f) of the 1933 Act) shall be entitled to contribution from any seller of Registrable Securities who was not guilty of such 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 1934 ACT.  With a view to making available to the Buyer the benefits of Rule 144 promulgated under the 1933 Act or any other similar rule or regulation of the SEC that may at any time permit the Buyer 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 1933 Act and the 1934 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 Purchase Agreement) and the filing of such reports and other documents is required for the applicable provisions of Rule 144; and

c.  furnish to the Buyer so long as the 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 1933 Act and the 1934 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.  ASSIGNMENT OF REGISTRATION RIGHTS.  The rights under this Agreement shall be assignable by the Buyers to any transferee of all or any portion of Registrable Securities, upon prior written consent of the Company, which consent shall not be unreasonably withheld, if:  (i) the Buyer agrees in writing with the transferee or assignee to assign such rights, and a copy of such agreement is furnished to the Company within a reasonab le time after such assignment, (ii) the Company is, within a reasonable time after such transfer or assignment, furnished with written notice of (a) the name and address of such transferee or assignee, and (b) the securities with respect to which such registration rights are being transferred or assigned, (iii) following such transfer or assignment, the further disposition of such securities by the transferee or assignee is restricted under the 1933 Act and applicable state securities laws, (iv) at or before the time the Company receives the written notice contemplated by clause (ii) of this sentence, the transferee or assignee agrees in writing with the Company to be bound by all of the provisions contained herein, and (v) such transfer shall have been made in accordance with the applicable requirements of the Purchase

12

Agreement or the Certificate of Designation.  In the event that the Buyer transfers all or any portion of its Registrable Securities pursuant to this Section, the Company shall have at least ten (10) days to file any amendments or supplements necessary to keep the Registration Statement current and effective pursuant to Rule 415, and the commencement date of any Event of Failure or Event of Default under the Certificate of Designation or the Warrants caused thereby will be extended by ten (10) days.

10.  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 pr ospectively), only with written consent of the Company, the Buyer (to the extent such Buyer still owns Registrable Securities) and Buyers who hold more than a sixty-six percent (66%) interest of the Registrable Securities; provided, however, that no consideration shall be paid to a Buyer by the Company in connection with an amendment hereto, unless each Buyer similarly affected by such amendment receives a pro-rata amount of consideration from the Company. Any amendment or waiver effected in accordance with this Section 10 shall be binding upon the Buyer and the Company.

11.  MISCELLANEOUS.

a.  A person or entity is deemed to be a holder of Registrable Securities whenever such person or entity owns of record such Registrable Securities. If the Company receives conflicting instructions, notices or elections from two or more persons or entities 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.  Any notices required or permitted to be given under the terms hereof shall be sent by certified or registered mail (return receipt requested) or delivered personally or by courier (including a recognized overnight delivery service) or by facsimile and shall be effective five days after being placed in the mail, if mailed by regular United States mail, or upon receipt, if delivered personally or by courier (including a recognized overnight delivery service) or by facsimile, in each case addressed to a party.  The addresses for such communications shall be:

c.  Failure of any party to exercise any right or remedy under this Agreement or otherwise, or delay by a party in exercising such right or remedy, shall not operate as a waiver thereof.

d.  Governing Law.  All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of conflicts of law thereof.  Each party agrees that all legal proceedings concerning the interpretations, enforcement and defense of the transactions contemplated by this Agreement (whether brought against a party hereto or its respective affiliates, directors, officers, shareholders, employees or agents) shall be commenced exclusively in the state and federal courts sitting in the City of New York.  Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the City of New York, Borough of Manhattan for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is improper or is an inconvenient venue for such proceeding.  Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof.  Nothing contained herein shall be deemed to limit in any way any right to serve process in any other manner permitted by law.  The parties hereby waive all rights to a trial by jury.  If either party shall commence an action or proceeding to enforce any provisions of the this Agreement, then the prevailing party in such action or proceeding shall be reimbursed by the other party for its reasonable attorneys’ fees and other costs and expenses incurred with the investigation, preparation and prosecution of such action or proceeding.

e.  This Agreement and the Purchase Agreement (including all schedules and exhibits thereto) constitute the entire agreement among the parties hereto with respect to the subject matter hereof and thereof. There are no restrictions, promises, warranties or undertakings, other than those set forth or referred to herein and therein. This Agreement and the Purchase Agreement supersede all prior agreements and understandings among the parties hereto with respect to the subject matter hereof and thereof.

f.  Subject to the requirements of Section 9 hereof, this Agreement shall inure to the benefit of and be binding upon the successors and assigns of each of the parties hereto.

g.  The headings in this Agreement are for convenience of reference only and shall not limit or otherwise affect the meaning hereof.

h.  This Agreement may be executed in two or more counterparts, each of which shall be deemed an original but all of which shall constitute one and the same agreement. This Agreement, once executed by a party, may be delivered to the other party hereto by facsimile transmission of a copy of this Agreement bearing the signature of the party so delivering this Agreement.

i.  Each party shall do and perform, or cause to be done and performed, all such further acts and things, and shall execute and deliver all such other agreements, certificates, instruments and

14

documents, as the other party may reasonably request in order to carry out the intent and accomplish the purposes of this Agreement and the consummation of the transactions contemplated hereby.

j.  Except as otherwise provided herein, all consents and other determinations to be made by the Buyer pursuant to this Agreement shall be made by Buyers holding a majority of the Registrable Securities, determined as if the all of the Preferred Stock and Warrants then outstanding have been converted or exercised into for Registrable Securities.

k.  The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Buyer by vitiating the intent and purpose of the transactions contemplated hereby. Accordingly, the Company acknowledges that the remedy at law for breach of its obligations hereunder will be inadequate and agrees, in the event of a breach or threatened breach by the Company of any of the provisions hereunder, that the Buyer shall be entitled, in addition to all other available remedies in law or in equity, to an injunction or injunctions to prevent or cure breaches of the provisions of this Agreement and to enforce specifically the terms and provisions hereof, without the necessity of showing economic loss and without any bond or other security being required.

l.  The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party.

m.  In the event that any provision of this Agreement is invalid or unenforceable under any applicable statute or rule of law, then such provision shall be deemed inoperative to the extent that it may conflict therewith and shall be deemed modified to conform with such statute or rule of law. Any provision hereof which may prove invalid or unenforceable under any law shall not affect the validity or enforceability of any other provision hereof.

n.  The initial number of Registrable Securities included in any Registration Statement and each increase to the number of Registrable Securities included therein shall be allocated pro rata among the Buyers based on the number of Registrable Securities held by the Buyer at the time of such establishment or increase, as the case may be. In the event a Buyer shall sell or otherwise transfer any of such holder’s Registrable Securities, each transferee shall be allocated a pro rata portion of the number of Registrable Securities included in a Registration Statement for such transferor.  Any shares of Common Stock included in a Registration Statement and which remain allocated to any person or entity which does not hold any Registrable Securities shall be allocated to the remaining Buyers, pro rata based on the number of shares of Registrable Securities then held by the Buyers.  For the avoidance of doubt, the number of Registrable Securities held by a Buyer shall be determined as if all the Preferred Stock and Warrants then outstanding and held by a Buyer were converted into or exercised for Registrable Securities, without regard to any limitation on the Buyer’s ability to convert the Preferred Stock or exercise the Warrants.

o.  There shall be no oral modifications or amendments to this Agreement.  This Agreement may be modified or amended only in writing.

15

IN WITNESS WHEREOF, the undersigned Buyers and the Company have caused this Registration Rights Agreement to be duly executed as of the 11th day of July, 2007.
