3.      Registration.

a.           Mandatory Registration.  The Company shall prepare, and, as soon as practicable but in no event later than the Filing Deadline, file with the SEC a Registration Statement on Form S-1 covering the resale of at least the number of shares of Common Stock equal to the Required Registration Amount determined as of date the Registration Statement is initially filed with the SEC.  Upon each Subsequent Closing (as defined in the Purchase Agreement), the Company shall prepare, and, as soon as practicable but in no event later than the 30 days after such Subsequent Closing, file with the SEC a Registration Statement on Form S-1 covering the resale of at least the number of s hares of Common Stock equal to the Required Registration Amount determined as of the date the Registration Statement is initially filed with the SEC. Each Registration Statement shall contain (except if otherwise directed by the Required Holders) the "Selling Stockholders" and "Plan of Distribution" sections for the Investors in substantially the form attached hereto as Exhibit B.  The Company shall use its reasonable best efforts to have each 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 Business Day following the Effective Date, the Company shall file with the SEC in accordance with Rule 424 under the Securities Act the final prospectus to be used in connection with sales pursuant to such Reg istration Statement.  Notwithstanding anything herein to the contrary, the Company has no obligation hereunder to include Cutback Shares, if any, on any Registration Statement.

b.           Allocation of Registrable Securities.  The initial number of Registrable Securities included in any Registration Statement and any increase or decrease in the number of Registrable Securities included therein shall be allocated pro rata among the Investors based on the number of Registrable Securities held by each Investor at the time the Registration Statement covering such initial number of Registrable Securities or increase or decrease thereof is declared effective by the SEC.  In the event that an Investor sells or otherwise transfers any of such Investor's Registrable Securities, each transferee shall be allocated a pro rata portion of the then remaining numbe r of Registrable Securities included in such Registration Statement for such transferor.  Any shares of Common Stock included in a Registration Statement and which remain allocated to any Person which ceases to hold any Registrable Securities covered by such Registration Statement shall be allocated to the remaining Investors, pro rata based on the number of Registrable Securities then held by such Investors which are covered by such Registration Statement.  In no event shall the Company include any securities other than Registrable Securities on any Registration Statement without the prior written consent of the Required Holders.

c.      Legal Counsel.  Subject to Section 6 hereof, the Required Holders shall have the right to select one legal counsel to review and oversee any registration pursuant to this Section 3 ("Legal Counsel"), which shall be Stubbs Alderton & Markiles, LLP or such other counsel as thereafter designated by the Required Holders with the consent of the Company, which consent shall not be unreasonably withheld or delayed.  The Company and Legal Counsel shall reasonably cooperate with each other in performing the Company's obligations under this Agreement.

4

d.      Ineligibility for Form S-3.  As Form S-3 is not available for the initial registration of the resale of Registrable Securities hereunder, the Company shall undertake to register the Registrable Securities on Form S-3 as soon as such form is available, provided that the Company shall maintain the effectiveness of the Registration Statement then in effect until such time as a Registration Statement on Form S-3 covering the Registrable Securities has been declared effective by the SEC.

e.      Sufficient Number of Shares Registered.  In the event the number of shares available under a Registration Statement filed pursuant to Section 3(a) is insufficient to cover the Required Registration Amount or an Investor's allocated portion of such Registrable Securities pursuant to Section 3(b), the Company shall amend the applicable Registration Statement, or file a new Registration Statement (on the short form available therefor, if applicable), or both, so as to cover at least the Required Registration Amount as of the Trading Day immediately preceding the date of the filing of such amendment or new Registration Statement, in each case, as soon as practicable, but in any event not later than fifteen ( 15) days after the necessity therefor arises.  The Company shall use its reasonable best efforts to cause such amendment and/or new Registration Statement to become effective as soon as practicable following the filing thereof.  For purposes of the foregoing provision, the number of shares available under a Registration Statement shall be deemed "insufficient to cover the Required Registration Amount" if at any time the number of shares of Common Stock available for resale under the Registration Statement is less than the product determined by multiplying (i) the Required Registration Amount as of such time by (ii) 0.90.  The calculation set forth in the foregoing sentence shall be made without regard to any limitations on the conversion of the Notes or the exercise of the Warrants and such calculation shall assume that the Notes are then convertible into shares of Common Stock at the then prevailing Conversion Rate (as defined in the Notes) and that the Warrants are then exerci sable for shares of Common Stock at the then prevailing Exercise Price (as defined in the Warrants).

f.      Effect of Failure to File and Obtain and Maintain Effectiveness of Registration Statement.  If (i) a Registration Statement covering all of the Registrable Securities required to be covered thereby and required to be filed by the Company pursuant to this Agreement is (A) not filed with the SEC on or before the Filing Deadline (a "Filing Failure") or (B) not declared effective by the SEC on or before the Effectiveness Deadline or Resolution Date (as defined below, if applicable) (an "Effectiveness Failure") or (ii) on any day during the Registration Period, and after the Effective Date, sales of all of the Registrable Securities required to be included on such Registration Statement cannot be made (other than during an Allowable Grace Period (as defined in Section 4(r)) pursuant to such Registration Statement (including, without limitation, because of a failure to keep such Registration Statement effective, to disclose such information as is necessary for sales to be made pursuant to such Registration Statement or to register a sufficient number of shares of Common Stock) (a "Maintenance Failure") then, as partial relief for the damages to any Investor by reason of any such delay in or reduction of its ability to sell the underlying shares of Common Stock (which remedy shall not be exclusive of any other remedies available at law or in equity), the Company shall pay to each Investor relating to such Registration Statement an amount in cash equal to (A) one percent (1.0%) of the aggregate Purchase Price (as such term is defined in the Securitie s Purchase Agreement) of such Investor's Registrable Securities included in such Registration Statement on each of the following dates: (i) the day of a Filing Failure and on every thirtieth day (pro rated for periods totaling less than thirty (30) days) thereafter until the date such Filing Failure is cured; (ii) the day of an Effectiveness Failure and on every thirtieth day (pro rated for periods totaling less than thirty (30) days) thereafter until the date such Effectiveness Failure is cured; and (iii) the initial day of a Maintenance Failure and on every thirtieth day (pro rated for periods totaling less than thirty (30) days) thereafter until the date such Maintenance Failure is cured.  The payments to which an Investor shall be entitled pursuant to this Section 3(f) are referred to herein as "Registration Delay Payments."  Registration Delay Payments shall be paid on the earlier of (I) the last day of the calendar month during which such Registration Delay Payments are incurred and (II) the third Business Day after the event or failure giving rise to the Registration Delay Payments is cured.  In the event the Company fails to make Registration Delay Payments in a timely manner, such Registration Delay Payments shall bear interest at the rate of one and one-half percent (1.5%) per month (prorated for partial months) until paid in full.  Notwithstanding anything herein to the contrary, (I) no Registration Delay Payments shall accrue with respect to Cutback Shares, if any; and (II) in the event that the SEC has not declared a Registration Statement effective on or before the Effectiveness Deadline solely as a result of unresolved comments or inquiries based on or arising from facts or circumstances of the Company occurring prior to the closing date of the Merger, and for no other reason, then the Registration Delay Payments applicable to an Effectiveness Failure shall not accrue and shall toll for each day follow ing the Effectiveness Deadline until the earlier of (x) the date that the Company and the SEC resolve all such comments or inquiries (the “Resolution Date”), and (y) the effective date of the Registration Statement.

5

g.      Neither the Company nor any Subsidiary (as defined in the Securities Purchase Agreement) nor affiliate thereof shall identify any Holder as an underwriter in any public disclosure or filing with the SEC or any Principal Market (as defined in the Securities Purchase Agreement) or any Trading Market (as defined in the Securities Purchase Agreement) and any Holder being deemed an underwriter by the SEC shall not relieve the Company of any obligations it has under this Agreement or any other Transaction Document (as defined in the Securities Purchase Agreement) provided, however, that the foregoing shall not prohibit the Company from including the disclosure found in the "Plan of Distribution" section attached hereto as Exhibit B in the Registration Statement.

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

a.      At least five (5) Business Days prior to the first anticipated filing date of a Registration Statement, the Company shall notify each Investor in writing of the information the Company requires from each such Investor if such Investor elects to have any of such Investor's Registrable Securities included in such Registration Statement.  It shall be a condition precedent to the obligations of the Company to complete the registration pursuant to this Agreement with respect to the Registrable Securities of a particular Investor that such Investor shall furnish to the Company such information regarding itself, the Registrable Securities held by it and the intended method of disposition of the Registrable Securities held by it as shall be reasonably required to effect the e ffectiveness of the registration of such Registrable Securities and shall execute such documents in connection with such registration as the Company may reasonably request.

b.      Each Investor, by such Investor's acceptance of the Registrable Securities, agrees to cooperate with the Company as reasonably requested by the Company in connection with the preparation and filing of any Registration Statement hereunder, unless such Investor has notified the Company in writing of such Investor's election to exclude all of such Investor's Registrable Securities from such Registration Statement.

c.      Each Investor agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 4(g) or the first sentence of 4(f), such Investor will immediately discontinue disposition of Registrable Securities pursuant to any Registration Statement(s) covering such Registrable Securities until such Investor's receipt of the copies of the supplemented or amended prospectus contemplated by Section 4(g) or the first sentence of 4(f) or receipt of notice that no supplement or amendment is required.  Notwithstanding anything to the contrary, the Company shall cause its transfer agent to deliver unlegended shares of Common Stock to a transferee of an Investor in accordance with the terms of the Securities Purchase Agreement in connec tion with any sale of Registrable Securities with respect to which an Investor has entered into a contract for sale prior to the Investor's receipt of a notice from the Company of the happening of any event of the kind described in Section 4(g) or the first sentence of 4(f) and for which the Investor has not yet settled.

12

d.      Each Investor covenants and agrees that it will comply with the prospectus delivery requirements of the Securities Act as applicable to it or an exemption therefrom in connection with sales of Registrable Securities pursuant to the Registration Statement.

6.      Expenses of Registration.

All expenses of Legal Counsel, which will lead the effort for the Company with respect to the initial filing of any Registration Statement (but not the maintenance thereof) will be paid by the Investors (jointly and severally), provided, however, if any Investor fails to pay their pro rata portion of such expenses, (i) the Registrable Securities held by such Investor shall be removed from the applicable Registration Statement (and accordingly, not registered thereunder), and (ii) the balance of such unpaid expenses shall be paid by the remaining Investors, pro rata.  All other reasonable expenses, other than underwriting discounts and commissions incurred in connection with registrations, filings or qualifications pursuant to Sections 3 and 4, including, without limitation, all registration, listing and qu alifications fees, printers and accounting fees, and fees and disbursements of counsel for the Company, shall be paid by the Company.

7.      Indemnification.

In the event any Registrable Securities 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 Investor, the directors, officers, members, partners, employees, agents, representatives of, and each Person, if any, who controls any Investor 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 app eal 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 t herein not misleading, (ii) any untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus if used prior to the effective date of such Registration Statement, or contained in the 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 the light of the circumstances under which the statements therein were made, not misleading, (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 thereunder relating to the offer or sale of the Registrable Securities pursuant to a Registration Statement or (iv) any violation of this Agreement (the matters in the foregoing clauses (i) through (iv) being, collectively, "Violations").  Subject to Section 7(c), the Company shall reimburse the Indemnified Persons, promptly as such expenses are incurred and are due and payable, for any legal fees 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 7(a):  (i) 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 for such Indemnified Person expressly for use in connection with the preparation of the Registration Statement or any such amendment thereof or supplement thereto, if such prospectus was timely made available by the Company pursuant to Section 4(d) and (ii) shall not apply to amounts paid in settlement of any Claim if such settlement is effect ed without the prior written consent of the Company, which consent shall not be unreasonably withheld or delayed.  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 Investors pursuant to Section 10.

13

b.      In connection with any Registration Statement in which an Investor is participating, each such Investor 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 7(a), the Company, each of its directors, each of its officers who signs the Registration Statement 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 are 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 Investor expressly for use in connection with such Registration Statement; and, subject to Section 7(c), such Investor shall reimburse the Indemnified Party, promptly as such expenses are incurred and are due and payable, for any legal fees or other reasonable expenses incurred by it in connection with investigating or defending any such Claim; provided, however, that the indemnity agreement contained in this Section 7(b) and the agreement with respect to contribution contained in Section 8 shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of such Investor, which consent shall not be unreasonably withheld or delayed; provided, further, however, that the Investor shall be liable under this Section 7(b) for only that amount of a Claim or Indemnified Damages as does not exceed the n et proceeds to such Investor 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 Investors pursuant to Section 10.

c.      Promptly after receipt by an Indemnified Person or Indemnified Party under this Section 7 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 7, 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 th e 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 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.  In the case of an Indemnified Person, legal counsel referred to in the immediately preceding sentence shall be selected by the Investors holding at least a majorityin inte rest of the Registrable Securities included in the Registration Statement to which the Claim relates.  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 reasonably 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 unreason ably 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, and such settlement shall not include any admission as to fault on the part of the Indemnified Party.  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 ind emnifying party of any liability to the Indemnified Person or Indemnified Party under this Section 7, except to the extent that the indemnifying party is prejudiced in its ability to defend such action.

14

d.      The indemnification required by this Section 7 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.

15

8.      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 7 to the fullest extent permitted by law; provided, however, that: (i) no Person involved in the sale of Registrable Securities, which Person is guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) in connection with such sale, shall be entitled to contribution from any Person involved in such sale of Registrable Securities who was not guilty of fraudulent misrepresentation; and (ii) contribution by any seller o f Registrable Securities shall be limited in amount to the amount of net proceeds received by such seller from the sale of such Registrable Securities pursuant to such Registration Statement.

9.      Reports Under the Exchange Act.

With a view to making available to the Investors the benefits of Rule 144 promulgated under the Securities Act or any other similar rule or regulation of the SEC that may at any time permit the Investors 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 and the filing of such reports and other documents is required for the applicable provisions of Rule 144; and

c.      furnish to each Investor so long as such Investor owns Registrable Securities, promptly upon request, (i) a written statement by the Company, if true, 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 Investors to sell such securities pursuant to Rule 144 without registration.

10.      Assignment of Registration Rights.

The rights under this Agreement shall be automatically assignable by the Investors to any transferee of all or any portion of such Investor's Registrable Securities if: (i) the Investor 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 reasonable 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) immediately following such transfer or assignment the further disposition of such securities by the transferee or assignee is restricted under the Securities Act or applicable state s ecurities 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 Securities Purchase Agreement.

16

11.      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 the Required Holders.  Any amendment or waiver effected in accordance with this Section 11 shall be binding upon each Investor and the Company.  No such amendment shall be effective to the extent that it applies to less than all of the Investors.  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.

12.      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.  If the Company receives conflicting instructions, notices or elections from two 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 record owner of such Registrable Securities.

b.      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.  The addresses and facsimile numbers for such communications shall be:
