11

7. Trading Restrictions.  At all times during the one-year period immediately following the Closing in which any Note Holder participates, beginning on the Closing Date, such Note Holder hereby agrees with the Company and the other Note Holders that such Note Holder shall not sell any shares of the Company's capital stock in excess of the greater of the following volume limitations: (a) on any one day, the number of shares equal to 10% of the Company's trading volume for the immediately preceding trading day and (b) in any 22 trading day period, the number of shares equal to 10% of the Company's trading volume for such 22 trading day period.  Notwithstanding the foregoing, the restrictions set forth in this Section 7 will terminate with respect to any Note Conversion Shares that are covered by an effective registration statement that may be filed by the Company.  The parties hereto acknowledge and agree that, except as set forth in this Agreement, the Company is under no obligation to register any of the Note Conversion Shares.

8. Miscellaneous.

(a) Legends.

i. The Note Holders hereby acknowledge that a legend may be placed on any certificates representing any of the Note Conversion Shares to the effect that the Note Conversion Shares represented by such certificates are subject to a hold period and may not be traded until the expiry of such hold period except as permitted by applicable securities legislation.

ii. The Note Holders hereby acknowledge and agree to the Company making a notation on its records or giving instructions to the registrar and transfer agent of the Company (along with any successor transfer agent of the Company, the "Transfer Agent") in order to implement the restrictions on transfer set forth and described in this Agreement.

iii. Certificates evidencing the Note Conversion Shares shall not contain any legend (including any legend under this Section 8(a)): (i) while a registration statement covering the resale of such security is effective under the Securities Act, (ii) following any sale of such Note Conversion Shares pursuant to Rule 144, (iii) if such Note Conversion Shares are eligible for sale under Rule 144 or (iv) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Securities and Exchange Commission). The Company shall cause its counsel to issue a legal opinion to the Transfer Agent promptly if required by the Transfer Agent to effect the removal of the legend hereunder. If all or any portion of a Note is converted at a time when there is an effective registration statement to cover the resale of the Note Conversion Shares, or if the Note Conversion Shares may be sold under Rule 144 or if such legend is not otherwise required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission) then such Note Conversion Shares shall be issued free of all legends. The Company agrees that following such time as such legend is no longer required under this Section 8(a), it will, no later than three business days following the delivery by a Note Holder to the Company or the Transfer Agent of a certificate representing Note Conversion Shares issued with a restrictive legend (such third business day, the "Legend Removal Date"), deliver or cause to be delivered to such Note Holder a certificate representing such shares that is free from all restrictive and other legends. The Company may not make any notation on its records or give instructions to the Transfer Agent that enlarge the restrictions on transfer set forth in this Section 8. Certificates for Note Conversion Shares subject to legend removal hereunder shall be transmitted by the Transfer Agent to the Note Holder by crediting the account of the Note Holder's prime broker with the Depository Trust Company System as directed by such Note Holder.

12

iv. In addition to the Note Holder's other available remedies, the Company shall pay to a Note Holder, in cash, as partial liquidated damages and not as a penalty, for each $1,000 of Note Conversion Shares (based on the VWAP of the Common Stock of the Company on the date such Note Conversion Shares are submitted to the Transfer Agent) delivered for removal of the restrictive legend and subject to Section 8(a)(iii), $10 per business day (increasing to $20 per business day five (5) business days after such damages have begun to accrue) for each business day after the Legend Removal Date until such certificate is delivered without a legend. Nothing herein shall limit such Note Holder's right to pursue actual damages for the Company's failure to deliver certificates representing any Note Conversion Shares as required by this Agreement, and such Note Holder shall have the right to pursue all remedies available to it at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief. For the purposes of this section, "VWAP" means, for any date, the price determined by the first of the following clauses that applies: (a) if the Common Stock is then listed or quoted on a Trading Market, the daily volume weighted average price of the Common Stock for such date (or the nearest preceding date) on the Trading Market on which the Common Stock is then listed or quoted as reported by Bloomberg L.P. (based on a Trading Day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York City time)), (b) if the OTC Bulletin Board is not a Trading Market, the volume weighted average price of the Common Stock for such date (or the nearest preceding date) on the OTC Bulletin Board, (c) if the Common Stock is not then listed or quoted for trading on the OTC Bulletin Board and if prices for the Common Stock are then reported in the "Pink Sheets" published by Pink OTC Markets, Inc. (or a similar organization or agency succeeding to its functions of reporting prices), the most recent bid price per share of the Common Stock so reported, or (d) in all other cases, the fair market value of a share of Common Stock as determined by an independent appraiser selected in good faith by the Purchasers of a majority in interest of the Securities then outstanding and reasonably acceptable to the Company, the fees and expenses of which shall be paid by the Company. For the purposes of this section, "Trading Market" means any of the following markets or exchanges on which the Common Stock is listed or quoted for trading on the date in question: the NYSE MKT, the Nasdaq Capital Market, the Nasdaq Global Market, the Nasdaq Global Select Market, the New York Stock Exchange, the OTC Bulletin Board, or any market of the OTC Markets, Inc. (or any successors to any of the foregoing).

(b) Registration Rights.  Holders of Note Conversion Shares will have the registration rights described in Exhibit B hereto.

(c) Transfers.  Subject to Section 7 above, the Company hereby confirms that it will not require a legal opinion or "no action" letter from any Note Holder who desires to transfer the Note Conversion Shares in compliance with Rule 144 promulgated by the Securities and Exchange Commission under the Securities Act ("Rule 144").

	
(d)

	
Furnishing of Information.

i. Until the earliest of the time that no Note Holder owns Notes or Note Conversion Shares, the Company covenants to maintain the registration of its Common Stock under Section 12(b) or 12(g) of the Exchange Act.  During the period that the Note Holders own Notes or Note Conversion Shares, the Company shall timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company pursuant to the Exchange Act, even if the Company is not then subject to the reporting requirements of the Exchange Act.

13

ii. At any time during the period commencing on the Closing Date and ending at such time that all of the Note Conversion Shares may be sold without the requirement for the Company to be in compliance with Rule 144(c)(1) and otherwise without restriction or limitation pursuant to Rule 144, if the Company shall fail for any reason to satisfy the current public information requirement under Rule 144(c) (a "Public Information Failure") then, in addition to such Note Holder's other available remedies, the Company shall pay to a Note Holder, in cash, as partial liquidated damages and not as a penalty, by reason of any such delay in or reduction of its ability to sell the Notes or Note Conversion Shares, an amount in cash equal to two percent (2.0%) of the aggregate principal amount of the Notes that were converted by such Note Holder pursuant to this Agreement on the day of a Public Information Failure and on every thirtieth (30th) day (pro rated for periods totaling less than thirty days) thereafter until the earlier of: (a) the date such Public Information Failure is cured, and (b) such time that such public information is no longer required for the Note Holders to transfer the Note Conversion Shares pursuant to Rule 144. The payments to which a Note Holder shall be entitled pursuant to this Section 8(d)(ii) are referred to herein as "Public Information Failure Payments." Public Information Failure Payments shall be paid on the earlier of (i) the last day of the calendar month during which such Public Information Failure Payments are incurred and (ii) the third (3rd) business day after the event or failure giving rise to the Public Information Failure Payments is cured. In the event the Company fails to make Public Information Failure Payments in a timely manner, such Public Information Failure Payments shall bear interest at the rate of 1.5% per month (prorated for partial months) until paid in full. Nothing herein shall limit such Note Holder's right to pursue actual damages for the Public Information Failure, and such Note Holder shall have the right to pursue all remedies available to it at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief.

(e) Tacking.  Each party hereto acknowledges that the holding period for the Note Conversion Shares may be tacked back to the date such Note cancelled and exchanged therefor was initially issued.

Each Note Holder acknowledges that the representations and warranties contained herein are made by it with the intention that such representations and warranties may be relied upon by the Company and its legal counsel in determining the Note Holder's eligibility to purchase the Note Conversion Shares under applicable securities legislation, or (if applicable) the eligibility of others on whose behalf it is contracting hereunder to purchase the Note Conversion Shares under applicable securities legislation.  The Note Holder further agrees that the representations and warranties made by the Note Holder will survive the Note Conversion and will continue in full force and effect notwithstanding any subsequent disposition of the Note Holder of such Note Conversion Shares.

EXHIBIT B

REGISTRATION RIGHTS

1.1 Company Registration.  If the Company shall determine to register any of its securities either for its own account or the account of a security holder or holders, other than a registration relating solely to employee benefit plans, a registration relating to a corporate reorganization or other Rule 145 transaction, or a registration on any registration form that does not permit secondary sales, the Company will:

(a) promptly give written notice of the proposed registration to all Note Holders; and

(b) use its commercially reasonable efforts to include in such registration (and any related qualification under blue sky laws or other compliance), except as set forth in Section 1.2 of this Exhibit B below, and in any underwriting involved therein, all of such Registrable Securities as are specified in a written request or requests made by any Note Holder or Note Holders received by the Company within 10 days after such written notice from the Company is mailed or delivered.  Such written request may specify all or a part of a Note Holder's Registrable Securities.

1.2 Underwriting.  If the registration of which the Company gives notice is for a registered public offering involving an underwriting, the Company shall so advise the Note Holders as a part of the written notice given pursuant to Section 1.1(a) of this Exhibit B.  In such event, the right of any Note Holder to registration pursuant to this Section 1.2 shall be conditioned upon such Note Holder's participation in such underwriting and the inclusion of such Note Holder's Registrable Securities in the underwriting to the extent provided herein.  All Note Holders proposing to distribute their securities through such underwriting shall (together with the Company, the Other Selling Stockholders and other holders of securities of the Company with registration rights to participate therein distributing their securities through such underwriting) enter into an underwriting agreement in customary form with the representative of the underwriter or underwriters selected by the Company.

Notwithstanding any other provision of this Section 1.2, if the underwriters advise the Company in writing that marketing factors require a limitation on the number of shares to be underwritten, the underwriters may (subject to the limitations set forth below) limit the number of Registrable Securities to be included in, the registration and underwriting.  The Company shall so advise all holders of securities requesting registration, and the number of shares of securities that are entitled to be included in the registration and underwriting shall be allocated, as follows: (i) first, to the Company for securities being sold for its own account, and (ii) second, to the Note Holders and Other Selling Stockholders requesting to include Registrable Securities and Other Shares in such registration statement based on the pro rata percentage of Registrable Securities and Other Shares held by such Note Holders and Other Selling Stockholders, assuming conversion and (iii) third, to the Other Selling Stockholders requesting to include Other Shares in such registration statement based on the pro rata percentage of Other Shares held by such Other Selling Stockholders, assuming conversion.

If a person who has requested inclusion in such registration as provided above does not agree to the terms of any such underwriting, such person shall also be excluded therefrom by written notice from the Company or the underwriter.  The Registrable Securities or other securities so excluded shall also be withdrawn from such registration.  Any Registrable Securities or other securities excluded or withdrawn from such underwriting shall be withdrawn from such registration.

1.3 Right to Terminate Registration.  The Company shall have the right to terminate or withdraw any registration initiated by it under this Exhibit B prior to the effectiveness of such registration whether or not any Note Holder has elected to include securities in such registration.

1.4 Definitions.  The following definitions shall apply for the purposes of this Exhibit B:

(a) "Other Selling Stockholders" shall mean persons other than Note Holders who, by virtue of agreements with the Company, are entitled to include their Other Shares in certain registrations hereunder.

(b) "Other Shares" shall mean shares of Common Stock, other than Registrable Securities (as defined below), with respect to which registration rights have been granted.

(c) "Registrable Securities" shall mean (i) shares of Common Stock issued or issuable pursuant to the conversion of the Notes and (ii) any Common Stock issued as a dividend or other distribution with respect to or in exchange for or in replacement of the shares referenced in (i) above; provided, however, that Registrable Securities shall not include any shares of Common Stock described in clause (i) or (ii) above which have previously been registered or which have been sold to the public either pursuant to a registration statement or Rule 144, or which have been sold in a private transaction in which the transferor's rights under this Agreement are not validly assigned in accordance with this Agreement.

Such Non-U.S. Warrant Holder: (i) is domiciled and has its principal place of business or registered office outside the United States; (ii) certifies it is not a U.S. person and is not acquiring the Warrant Shares for the account or benefit of any U.S. person; and (iii) at the time of Closing, the Non-U.S. Warrant Holder or persons acting on the Non-U.S. Warrant Holder's behalf in connection therewith are located outside the United states.

(g) Distributor; Dealer.  Such Non-U.S. Warrant Holder is not a "distributor" (as defined in Regulation S) or a "dealer" (as defined in the Securities Act).

Such Non-U.S. Warrant Holder is satisfied as to the full observance of the laws of such Non-U.S. Warrant Holder's jurisdiction in connection with the Warrant Exercise, including (i) the legal requirements within such Non-U.S. Warrant Holder's jurisdiction for the Warrant Exercise, (ii) any foreign Warrant Exercise restrictions applicable to such Warrant Exercise, (iii) any governmental or other consents that may need to be obtained and (iv) the income tax and other tax consequences, if any, that may be relevant to the Warrant Exercise, holding, redemption, sale or transfer of such securities.  Such Non-U.S. Warrant Holder's participation in the Warrant Exercise, and such Non-U.S. Warrant Holder's continued beneficial ownership of the Warrant Shares will not violate any applicable securities or other laws of such Non-U.S. Warrant Holder's jurisdiction.

6. Waiver and Release.

(a) Each Warrant Holder expressly forfeits and waives any and all anti-dilution and piggyback registration rights under any and all Prior Transaction Documents or otherwise applicable to the Warrants, including any anti-dilution rights such Warrant Holder may have with respect to the issuances of any capital stock or other securities of the Company pursuant to previous transactions and pursuant to this Agreement.

(b) Each Warrant Holder unconditionally, irrevocably and absolutely releases and discharges the Company, and any parent and subsidiary corporations, divisions and affiliated corporations, partnerships or other entities of the Company, past and present, as well as the Company's past and present employees, officers, directors, agents, principals, shareholders, successors and assigns from all claims, losses, demands, interests, causes of action, suits, debts, controversies, liabilities, costs, expenses and damages related to the waiver of anti-dilution and piggyback registration rights above, any security interest pursuant to any Prior Transaction Documents or otherwise over any collateral of the Company, or related in any way to any rights such Warrant Holder may have to equity or debt securities of the Company, other than as set forth on the schedules hereto.  This release includes, but is not limited to, any tort, contract, common law, constitution or other statutory claims (including but not limited to any claims for attorneys' fees, costs and expenses).

11

(c) Each of the Warrant Holders and the Company expressly waives such Warrant Holder's or Company's (as applicable) right to recovery of any type, including damages or reinstatement, in any administrative court or action, whether state or federal, and whether brought by such Warrant Holder or Company or on such Warrant Holder's or Company's (as applicable) behalf, related in any way to the matters released herein.

(d) Each of the Warrant Holders and the Company acknowledges that it may discover facts or law different from, or in addition to, the facts or law that it knows or believes to be true with respect to the claims released in this Agreement and agrees, nonetheless, that this Agreement and the release contained in it shall be and remain effective in all respects notwithstanding such different or additional facts or the discovery of them.

(e) Each of the Warrant Holders and the Company declares and represents that it intends this Agreement to be complete and not subject to any claim of mistake, and that the release of the claims described herein expresses a full and complete release and it intends the release of such claims to be final and complete.

(f) The parties acknowledge that this release is not intended to bar any claims that, by statute, may not be waived.

7. Trading Restrictions.  At all times during the one-year period immediately following the Closing, beginning on the Closing Date, each Warrant Holder hereby agrees with the Company and the other Warrant Holders that such Warrant Holder shall not sell any shares of the Company's capital stock in excess of the greater of the following volume limitations: (a) on any one day, the number of shares equal to 10% of the Company's trading volume for the immediately preceding trading day and (b) in any 22 trading day period, the number of shares equal to 10% of the Company's trading volume for such 22 trading day period.  Notwithstanding the foregoing, the restrictions set forth in this Section 7 will terminate with respect to any Warrant Shares that are covered by an effective registration statement that may be filed by the Company.  The parties hereto acknowledge and agree that the Company is under no obligation to register any of the Warrant Shares.

8. Miscellaneous.

	
(a)

	
Legends.

i. The Warrant Holders hereby acknowledge that a legend may be placed on any certificates representing any of the Warrant Shares to the effect that the Warrant Shares represented by such certificates are subject to a hold period and may not be traded until the expiry of such hold period except as permitted by applicable securities legislation.

ii. The Warrant Holders hereby acknowledge and agree to the Company making a notation on its records or giving instructions to the registrar and transfer agent of the Company (along with any successor transfer agent of the Company, the "Transfer Agent") in order to implement the restrictions on transfer set forth and described in this Agreement.

12

iii. Certificates evidencing the Warrant Shares shall not contain any legend (including any legend under this Section 8(a)): (i) while a registration statement covering the resale of such security is effective under the Securities Act, (ii) following any sale of such Warrant Shares pursuant to Rule 144, (iii) if such Warrant Shares are eligible for sale under Rule 144 or (iv) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Securities and Exchange Commission). The Company shall cause its counsel to issue a legal opinion to the Transfer Agent promptly if required by the Transfer Agent to effect the removal of the legend hereunder. If all or any portion of a Warrant is exercised at a time when there is an effective registration statement to cover the resale of the Warrant Shares, or if the Warrant Shares may be sold under Rule 144 or if such legend is not otherwise required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission) then such Warrant Shares shall be issued free of all legends. The Company agrees that following such time as such legend is no longer required under this Section 8(a), it will, no later than three business days following the delivery by a Warrant Holder to the Company or the Transfer Agent of a certificate representing Warrant Shares issued with a restrictive legend (such third business day, the "Legend Removal Date"), deliver or cause to be delivered to such Warrant Holder a certificate representing such shares that is free from all restrictive and other legends. The Company may not make any notation on its records or give instructions to the Transfer Agent that enlarge the restrictions on transfer set forth in this Section 8. Certificates for Warrant Shares subject to legend removal hereunder shall be transmitted by the Transfer Agent to the Warrant Holder by crediting the account of the Warrant Holder's prime broker with the Depository Trust Company System as directed by such Warrant Holder.

iv. In addition to the Warrant Holder's other available remedies, the Company shall pay to a Warrant Holder, in cash, as partial liquidated damages and not as a penalty, for each $1,000 of Warrant Shares (based on the VWAP of the Common Stock of the Company on the date such Warrant Shares are submitted to the Transfer Agent) delivered for removal of the restrictive legend and subject to Section 8(a)(iii), $10 per business day (increasing to $20 per business day five (5) business days after such damages have begun to accrue) for each business day after the Legend Removal Date until such certificate is delivered without a legend. Nothing herein shall limit such Warrant Holder's right to pursue actual damages for the Company's failure to deliver certificates representing any Warrant Shares as required by this Agreement, and such Warrant Holder shall have the right to pursue all remedies available to it at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief. For the purposes of this section, "VWAP" means, for any date, the price determined by the first of the following clauses that applies: (a) if the Common Stock is then listed or quoted on a Trading Market, the daily volume weighted average price of the Common Stock for such date (or the nearest preceding date) on the Trading Market on which the Common Stock is then listed or quoted as reported by Bloomberg L.P. (based on a Trading Day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York City time)), (b) if the OTC Bulletin Board is not a Trading Market, the volume weighted average price of the Common Stock for such date (or the nearest preceding date) on the OTC Bulletin Board, (c) if the Common Stock is not then listed or quoted for trading on the OTC Bulletin Board and if prices for the Common Stock are then reported in the "Pink Sheets" published by Pink OTC Markets, Inc. (or a similar organization or agency succeeding to its functions of reporting prices), the most recent bid price per share of the Common Stock so reported, or (d) in all other cases, the fair market value of a share of Common Stock as determined by an independent appraiser selected in good faith by the Purchasers of a majority in interest of the Securities then outstanding and reasonably acceptable to the Company, the fees and expenses of which shall be paid by the Company. For the purposes of this section, "Trading Market" means any of the following markets or exchanges on which the Common Stock is listed or quoted for trading on the date in question: the NYSE MKT, the Nasdaq Capital Market, the Nasdaq Global Market, the Nasdaq Global Select Market, the New York Stock Exchange, the OTC Bulletin Board, or any market of the OTC Markets, Inc. (or any successors to any of the foregoing).

(b) Registration Rights.  Holders of Warrant Shares will have the registration rights described in Exhibit B hereto.

(c) Transfers.  Subject to Section 7 above, the Company hereby confirms that it will not require a legal opinion or "no action" letter from any Warrant Holder who desires to transfer the Warrant Shares in compliance with Rule 144 promulgated by the Securities and Exchange Commission under the Securities Act ("Rule 144").

13

(d) Tacking.  Each party hereto acknowledges that the holding period for the Warrant Shares may be tacked back to the date such Warrant exercised therefor was initially issued.

(e) Furnishing of Information.

i. Until the earliest of the time that no Warrant Holder owns Warrant or Warrant Shares, the Company covenants to maintain the registration of its Common Stock under Section 12(b) or 12(g) of the Exchange Act.  During the period that the Warrant Holders own Warrants or Warrant Shares, the Company shall timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company pursuant to the Exchange Act, even if the Company is not then subject to the reporting requirements of the Exchange Act.

ii. At any time during the period commencing on the Closing Date and ending at such time that all of the Warrant Shares may be sold without the requirement for the Company to be in compliance with Rule 144(c)(1) and otherwise without restriction or limitation pursuant to Rule 144, if the Company shall fail for any reason to satisfy the current public information requirement under Rule 144(c) (a "Public Information Failure") then, in addition to such Warrant Holder's other available remedies, the Company shall pay to a Warrant Holder, in cash, as partial liquidated damages and not as a penalty, by reason of any such delay in or reduction of its ability to sell the Warrants or Warrant Shares, an amount in cash equal to two percent (2.0%) of the aggregate exercise price of the Warrants that were exercised by such Warrant Holder pursuant to this Agreement on the day of a Public Information Failure and on every thirtieth (30th) day (pro rated for periods totaling less than thirty days) thereafter until the earlier of: (a) the date such Public Information Failure is cured, and (b) such time that such public information is no longer required for the Warrant Holders to transfer the Warrant Shares pursuant to Rule 144. The payments to which a Warrant Holder shall be entitled pursuant to this Section 8(d)(ii) are referred to herein as "Public Information Failure Payments." Public Information Failure Payments shall be paid on the earlier of (i) the last day of the calendar month during which such Public Information Failure Payments are incurred and (ii) the third (3rd) business day after the event or failure giving rise to the Public Information Failure Payments is cured. In the event the Company fails to make Public Information Failure Payments in a timely manner, such Public Information Failure Payments shall bear interest at the rate of 1.5% per month (prorated for partial months) until paid in full. Nothing herein shall limit such Warrant Holder's right to pursue actual damages for the Public Information Failure, and such Warrant Holder shall have the right to pursue all remedies available to it at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief.

(f) Reliance on Representations and Warranties by the Company.  Each Warrant Holder acknowledges that the representations and warranties contained herein are made by it with the intention that such representations and warranties may be relied upon by the Company and its legal counsel in determining the Warrant Holder's eligibility to purchase the Warrant Shares under applicable securities legislation, or (if applicable) the eligibility of others on whose behalf it is contracting hereunder to purchase the Warrant Shares under applicable securities legislation.  The Warrant Holder further agrees that the representations and warranties made by the Warrant Holder will survive the Warrant Exercise and will continue in full force and effect notwithstanding any subsequent disposition of the Warrant Holder of such Warrant Shares.

(g) Fees and Expenses.  Each party shall pay the fees and expenses of its advisors, counsel, accountants and other experts, if any, and all other expenses incurred by such party incident to the preparation, execution, delivery and performance of this Agreement.

No waiver with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of any party to exercise any right hereunder in any manner impair the exercise of any such right.

EXHIBIT B

REGISTRATION RIGHTS

1.1 Company Registration.  If the Company shall determine to register any of its securities either for its own account or the account of a security holder or holders, other than a registration relating solely to employee benefit plans, a registration relating to a corporate reorganization or other Rule 145 transaction, or a registration on any registration form that does not permit secondary sales, the Company will:

(a) promptly give written notice of the proposed registration to all Warrant Holders; and

(b) use its commercially reasonable efforts to include in such registration (and any related qualification under blue sky laws or other compliance), except as set forth in Section 1.2 of this Exhibit B below, and in any underwriting involved therein, all of such Registrable Securities as are specified in a written request or requests made by any Warrant Holder or Warrant Holders received by the Company within 10 days after such written notice from the Company is mailed or delivered.  Such written request may specify all or a part of a Warrant Holder's Registrable Securities.

1.2 Underwriting.  If the registration of which the Company gives notice is for a registered public offering involving an underwriting, the Company shall so advise the Warrant Holders as a part of the written notice given pursuant to Section 1.1(a) of this Exhibit B.  In such event, the right of any Warrant Holder to registration pursuant to this Section Error! Reference source not found. shall be conditioned upon such Warrant Holder's participation in such underwriting and the inclusion of such Warrant Holder's Registrable Securities in the underwriting to the extent provided herein.  All Warrant Holders proposing to distribute their securities through such underwriting shall (together with the Company, the Other Selling Stockholders and other holders of securities of the Company with registration rights to participate therein distributing their securities through such underwriting) enter into an underwriting agreement in customary form with the representative of the underwriter or underwriters selected by the Company.

Notwithstanding any other provision of this Section Error! Reference source not found., if the underwriters advise the Company in writing that marketing factors require a limitation on the number of shares to be underwritten, the underwriters may (subject to the limitations set forth below) limit the number of Registrable Securities to be included in, the registration and underwriting.  The Company shall so advise all holders of securities requesting registration, and the number of shares of securities that are entitled to be included in the registration and underwriting shall be allocated, as follows: (i) first, to the Company for securities being sold for its own account, and (ii) second, to the Warrant Holders and Other Selling Stockholders requesting to include Registrable Securities and Other Shares in such registration statement based on the pro rata percentage of Registrable Securities and Other Shares held by such Warrant Holders and Other Selling Stockholders, assuming exercise and (iii) third, to the Other Selling Stockholders requesting to include Other Shares in such registration statement based on the pro rata percentage of Other Shares held by such Other Selling Stockholders, assuming exercise.

If a person who has requested inclusion in such registration as provided above does not agree to the terms of any such underwriting, such person shall also be excluded therefrom by written notice from the Company or the underwriter.  The Registrable Securities or other securities so excluded shall also be withdrawn from such registration.  Any Registrable Securities or other securities excluded or withdrawn from such underwriting shall be withdrawn from such registration.

1.3 Right to Terminate Registration.  The Company shall have the right to terminate or withdraw any registration initiated by it under this Exhibit B prior to the effectiveness of such registration whether or not any Warrant Holder has elected to include securities in such registration.

1.4 Definitions.  The following definitions shall apply for the purposes of this Exhibit B:

(a) "Other Selling Stockholders" shall mean persons other than Warrant Holders who, by virtue of agreements with the Company, are entitled to include their Other Shares in certain registrations hereunder.

(b) "Other Shares" shall mean shares of Common Stock, other than Registrable Securities (as defined below), with respect to which registration rights have been granted.

(c) "Registrable Securities" shall mean (i) shares of Common Stock issued or issuable pursuant to the exercise of the Warrants and (ii) any Common Stock issued as a dividend or other distribution with respect to or in exchange for or in replacement of the shares referenced in (i) above; provided, however, that Registrable Securities shall not include any shares of Common Stock described in clause (i) or (ii) above which have previously been registered or which have been sold to the public either pursuant to a registration statement or Rule 144, or which have been sold in a private transaction in which the transferor's rights under this Agreement are not validly assigned in accordance with this Agreement.
