Registration Rights

4.1

Shelf Registration

4.1.1

If the Company shall receive at any time after the Termination Date a written request from the Investor to file a registration statement on Form S-3 or an equivalent form or forms covering the registration of the Registrable Securities, the Company will use its commercially reasonable efforts to file, within thirty (30) days after the receipt of such request, a registration statement on Form S-3 or any equivalent form or forms (the “Resale Shelf Registration Statement”) and shall use its commercially reasonable efforts to cause such Resale Shelf Registration Statement to be declared effective by the SEC as soon as reasonably practicable after the filing thereof, and such Resale Shelf Registration Statement (i) will be a “shelf” registration statement providing for the registration, and the sale on a continuous or delayed basis, of all of the Registrable Securities pursuant to Rule 415 under the Securities Act and (ii) will not provide for the registration, and the sale on a continuous or delayed basis, of any Common Stock other than the Registrable Securities. Upon filing a Resale Shelf Registration Statement, the Company will, if applicable, use its commercially reasonable efforts to keep such Resale Shelf Registration Statement effective with the SEC for nine months following the date of the initial effectiveness of the Resale Shelf Registration Statement; provided that such nine month period shall be extended by any period or periods of time during which the Resale Registration Statement (taken together with any Subsequent Shelf Registration) is unavailable for sales of Registrable

Securities, whether as provided in Section 4.1.2, Section 4.5 or otherwise (such nine month period, as extended, the “Resale Effectiveness Period”).

	4.1.2		If any Resale Shelf Registration Statement or subsequent Registration Statement (a “Subsequent Shelf Registration”) ceases to be effective under the Securities Act for any reason at any time within the Resale Effectiveness Period, including the expiration thereof, the Company shall use its commercially reasonable efforts to cause such Resale Shelf Registration Statement or Subsequent Shelf Registration, respectively, to again become effective under the Securities Act (including obtaining the prompt withdrawal of any order suspending the effectiveness of such Resale Shelf Registration Statement), and in any event shall within thirty (30) days of such cessation of effectiveness, amend such Resale Shelf Registration Statement or Subsequent Shelf Registration, respectively, in a manner reasonably expected to obtain the withdrawal of any order suspending the effectiveness of such Resale Shelf Registration Statement or Subsequent Shelf Registration, respectively, or file an additional registration statement providing for the registration, and the sale on a continuous or delayed basis, of all of the Registrable Securities pursuant to Rule 415 under the Securities Act; provided that such Subsequent Shelf Registration will not provide for the registration, and the sale on a continuous or delayed basis, of any Common Stock other than the Registrable Securities. If a Subsequent Shelf Registration is filed, the Company shall use its commercially reasonable efforts to (x) cause such Subsequent Shelf Registration to become effective under the Securities Act as soon as reasonably practicable after such filing and (y) keep such Subsequent Shelf Registration (or another Subsequent Shelf Registration) continuously effective with the SEC at all times during the Resale Effectiveness Period. Any such Subsequent Shelf Registration shall be a registration statement on Form S-3 to the extent that the Company is eligible to use such form. For the avoidance of doubt, the Company shall not be required to maintain a Resale Shelf Registration Statement or Subsequent Shelf Registration after the end of the Resale Effectiveness Period.
	4.1.3		If for any reason the Company is unable to qualify as a registrant to register the Registrable Securities on Form S-3 or any equivalent form or forms or any similar registration in accordance with Section 4.1.1 or Section 4.1.2, as applicable, the Company shall use commercially reasonable efforts to file a registration statement on Form S-1 or any equivalent form or forms within thirty (30) days of such failure to qualify in order to provide for the registration of such Registrable Securities for resale by the Investor in accordance with any reasonable method of distribution elected by the Investor.

	4.1.4		If the Investor intends that any Registrable Securities covered by any registration pursuant to Section 4.1 shall be distributed by means of an underwritten offering, the Investor will so advise the Company. In such event, the managing underwriter to administer the offering will be chosen by the Investor, subject to the prior written consent of the Company, such consent not to be unreasonably withheld, conditioned or delayed. Unless otherwise mutually agreed by the Company and the Investor, the Company and the Investor shall enter into an underwriting agreement in such reasonable and customary form as shall have been negotiated and agreed to by the Company with the underwriter or underwriters selected for such underwriting. If the Investor disapproves of the terms of the underwriting, the Investor may promptly elect to withdraw therefrom by written notice to the Company and the managing underwriter.
	4.1.5		If the managing underwriter in any underwritten offering pursuant to this Section 4.1, advises the Company that in its reasonable opinion the number of securities requested by the Investor to be included in such distribution exceeds the number which can be sold without adversely affecting the marketability of such offering (including an adverse effect on the per share offering price), the Investor will include in such distribution only such number of securities that in the reasonable opinion of such underwriter can be sold without adversely affecting the marketability of the offering (including an adverse effect on the per share offering price).
	4.1.6		Notwithstanding the foregoing, if the Company shall furnish to the Investor a certificate signed by the Chief Executive Officer of the Company stating that in the good faith judgment of the Board it would be detrimental to the Company and its stockholders for such Resale Shelf Registration Statement to be filed, the Company shall have the right to defer such filing for a period of not more than sixty (60) days after receipt of the request by the Investor; provided, however, that the Company shall not register any securities for the account of itself or any other stockholder during such sixty (60) day period.
	4.1.7		In addition, the Company shall not be obligated to effect or to take any action to effect, any registration pursuant to this Section 4.1 after the Company has effected one (1) registration pursuant to this Section 4.1; provided, however, that such registration has been declared or ordered effective and has been available for sales of Registrable Securities for the entire Resale Effectiveness Period.

4.2

Piggyback Registrations

4.2.1

Whenever the Company proposes to register any of its Common Stock in connection with an underwritten public offering of such securities solely for cash, other than a registration on Form S-4 or Form S-8 (or any successor form), and the registration form to be filed may be used for the

registration or qualification for distribution of Registrable Securities by the Company, the Company will give prompt written notice to the Investor of its intention to effect such a registration (but in no event less than ten (10) Business Days prior to the anticipated filing date) and, subject to Section 4.2.3, will include in such registration all Registrable Securities with respect to which the Company has received written requests for inclusion therein from the Investor within ten (10) Business Days after the date of the Company’s notice (a “Piggyback Registration Statement”). The Investor may withdraw its Registrable Securities from such Piggyback Registration Statement by giving prompt written notice to the Company and the managing underwriter, if any, on or before the fifth (5th) Business Day prior to the planned effective date of such Piggyback Registration Statement. The Company may terminate or withdraw any registration under this Section 4.2.1 prior to the effectiveness of such registration, whether or not the Investor has elected to include Registrable Securities in such registration.

	4.2.2		The right of the Investor to registration pursuant to this Section 4.2 will be conditioned upon the Investor’s participation in the underwriting and the inclusion of the Investor’s Registrable Securities in the underwriting, and the Company and the Investor will (together with any other Persons distributing their securities through such underwriting) enter into an underwriting agreement (including all reasonable and customary questionnaires, powers of attorney, indemnities, lock-up letters and other documents required under the terms of such underwriting agreement) in such reasonable and customary form as shall have been negotiated and agreed to by the Company with the underwriter or underwriters selected for such underwriting by the Company. If the Investor disapproves of the terms of the underwriting, the Investor may elect to withdraw therefrom by written notice to the Company and the managing underwriter.
	4.2.3		If the managing underwriter in any underwritten offering pursuant to a Piggyback Registration Statement advises the Company that in its sole and reasonable opinion the number of securities requested to be included in such registration exceeds the number which can be sold without adversely affecting the marketability of such offering (including an adverse effect on the per share offering price), the Company will include in such registration only such number of securities that in the reasonable opinion of such underwriter can be sold without adversely affecting the marketability of the offering (including an adverse effect on the per share offering price), which securities will be so included in the following order of priority: (i) first, the securities the Company proposes to sell and (ii) second, the Registrable Securities of the Investor and any other securities of the Company that have been requested by other holders of Common Stock having registration rights to be so included, on a pro rata basis, up to the maximum number of securities the managing underwriter advises the

Company may be sold without adversely affecting the marketability of such offering.

4.3

Upon the reasonable request of the Investor, the Company will deliver to the Investor a written statement as to whether it has complied with such information requirements, and, if not, the specifics thereof.

4.7

Additional Interest

In the event the Company fails to file the Resale Shelf Registration Statement within sixty (60) days of receipt by the Company of a request from the Investor pursuant to Section 4.1.1 (or ninety (90) days to the extent the Company exercises its righs under Section 4.1.6), the Company will pay to the Investor (i) if prior to the Maturity Date, on the next applicable Interest Payment Date, an amount equivalent to 0.5% per annum on the principal amount of the Convertible Loans that have been converted into Registrable Securities and (ii) if from and after the Maturity Date, on the last day of each fiscal month of the Company, 1.0% per annum on the principal amount of the Convertible Loans that have been converted into Registrable Securities, in each case, for each day that such filing is late.

5			Indemnification

5.1.1

The Company will, with respect to any Registrable Securities as to which registration or qualification or compliance under applicable “blue sky” laws has been effected pursuant to this Agreement, indemnify and hold harmless the Investor, the Investor’s officers, directors, partners and members, and each person controlling the Investor within the meaning of Section 15 of the Securities Act, and each underwriter thereof, if any, and each person who controls any such underwriter within the meaning of Section 15 of the Securities Act (collectively, the “Company Indemnified Parties”), against all expenses, claims, losses, damages and liabilities, joint or several (or actions in respect thereof) arising out of or based on (i) any untrue statement (or alleged untrue statement) of a material fact contained in any registration statement, prospectus, preliminary prospectus, offering circular or other document, or any amendment or supplement thereto incident to any such registration, qualification or compliance or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, or (ii) any violation by the Company of any rule or regulation promulgated under the Securities Act, Exchange Act or other federal or state securities laws applicable to the Company in connection with any such registration, qualification or compliance, and, in each such

case, the Company will reimburse each of the Company Indemnified Parties for any reasonable legal and any other expenses reasonably incurred in connection with investigating, preparing or defending any such claim, loss, damage, liability or action, as such expenses are incurred, in each case. The indemnity agreement contained in this Section 5.1.1 shall not apply to amounts paid in settlement of any loss, claim, damage, liability or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld, conditioned or delayed), nor shall the Company be liable to the Company Indemnified Parties in any such case for any such loss, claim, damage, liability or action (i) to the extent that it arises out of or is based upon a violation or alleged violation of any state or federal law (including any claim arising out of or based on any untrue statement or alleged untrue statement or omission or alleged omission in the registration statement or prospectus) which occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by or on behalf of a Company Indemnified Party or (ii) in the case of a sale directly by the Investor of Registrable Securities (including a sale of such Registrable Securities through any underwriter retained by the Investor engaging in a distribution solely on behalf of the Investor), such untrue statement or alleged untrue statement or omission or alleged omission was corrected in a final or amended prospectus delivered to the Investor prior to the confirmation of the sale of the Registrable Securities to the person asserting any such loss, claim, damage or liability, and the Investor failed to deliver a copy of the final or amended prospectus at or prior to the confirmation of the sale of the Registrable Securities to the person asserting any such loss, claim, damage or liability in any case in which such delivery is required by the Securities Act.

5.1.2

The Investor will, if Registrable Securities held by the Investor are included in the securities as to which such registration or qualification or compliance under applicable “blue sky” laws is being effected, indemnify and hold harmless the Company, each of its directors, officers, partners and members, each underwriter, if any, of the Company’s securities covered by such a registration, and each person who controls the Company or such underwriter within the meaning of Section 15 of the Securities Act (collectively, the “Investor Indemnified Parties”), against all expenses, claims, losses, damages and liabilities, joint or several (or actions in respect thereof) arising out of or based on (i) any untrue statement (or alleged untrue statement) of a material fact contained in any registration statement, prospectus, preliminary prospectus, offering circular or other document, or any amendment or supplement thereto incident to any such registration, qualification or compliance or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, to the extent, but only to the extent, that such untrue statement (or alleged untrue statement)

or omission (or alleged omission) is made in such registration statement, prospectus, offering circular or other document in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Investor and stated to be specifically for use therein, or (ii) any violation by the Investor of any rule or regulation promulgated under the Securities Act, Exchange Act or state securities law applicable to the Investor in connection with such registration, qualification or compliance, and in each such case the Investor will reimburse each of the Investor Indemnified Parties for any reasonable legal or any other expenses reasonably incurred in connection with investigating, preparing or defending any such claim, loss, damage, liability or action, as such expenses are incurred, in each case, provided, however, that in no event shall any indemnity under this Section 5.1.2 payable by the Investor exceed the amount by which (x) the net proceeds actually received by the Investor from the sale of Registrable Securities included in such registration exceeds (y) the amount of any other losses, expenses, settlements, damages, claims and liabilities that the Investor has been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission or violation. The indemnity agreement contained in this Section 5.1.2 shall not apply to amounts paid in settlement of any loss, claim, damage, liability or action if such settlement is effected without the consent of the Investor (which consent shall not be unreasonably withheld, conditioned or delayed), nor shall the Investor be liable to any Investor Indemnified Party for any such loss, claim, damage, liability or action where such untrue statement or alleged untrue statement or omission or alleged omission was corrected in a final or amended prospectus prior to the confirmation of the sale of the Registrable Securities to the person asserting any such loss, claim, damage or liability, and the Company or the underwriters failed to deliver a copy of the final or amended prospectus at or prior to the confirmation of the sale of the Registrable Securities to the person asserting any such loss, claim, damage or liability in any case in which such delivery is required by the Securities Act.

5.1.3

Each party entitled to indemnification under this Section 5 (the “Indemnified Party”) shall give written notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to participate or to assume the defense of any such claim or any litigation resulting therefrom, provided, however, that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not unreasonably be withheld, conditioned or delayed), and the Indemnified Party may participate in such defense at such party’s expense; provided, further, however, that an Indemnified Party (together with all other Indemnified Parties which may be represented without conflict by one

counsel) shall have the right to retain one separate counsel, with the reasonable fees and expenses to be paid by the Indemnifying Party, if representation of such Indemnified Party by the counsel retained by the Indemnifying Party would be inappropriate due to conflicting interests between such Indemnified Party and any other party represented by such counsel in such proceeding. The failure of any Indemnified Party to give notice as provided herein shall relieve the Indemnifying Party of its obligations under this Section 5 only to the extent that the failure to give such notice is materially prejudicial or harmful to an Indemnifying Party’s ability to defend such action. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent of each Indemnified Party (which consent shall not be unreasonably withheld, conditioned or delayed), consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation. The indemnity agreements contained in this Section 5 shall not apply to amounts paid in settlement of any loss, claim, damage, liability or action if such settlement is effected without the consent of the Indemnifying Party, which consent shall not be unreasonably withheld, conditioned or delayed. The indemnification set forth in this Section 5 shall be in addition to any other indemnification rights or agreements that an Indemnified Party may have.

5.1.4

If the indemnification provided for in this Section 5 is held by a court of competent jurisdiction to be unavailable to an Indemnified Party, other than pursuant to its terms, with respect to any claim, loss, damage, liability or action referred to therein, then, subject to the limitations contained in the last sentence of this Section 5.1.4, the Indemnifying Party, in lieu of indemnifying such Indemnified Party hereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such claim, loss, damage, liability or action in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and the Indemnified Party on the other in connection with the actions that resulted in such claims, loss, damage, liability or action, as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party and of the Indemnified Party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact related to information supplied by the Indemnifying Party or by the Indemnified Party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Investor agree that it would not be just and equitable if contribution pursuant to this Section 5.1.4 were based solely upon the number of entities from whom contribution was requested or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 5.1.4. In no event shall the Investor’s contribution obligation under this Section 5.1.4 exceed (i) the

amount by which the net proceeds actually received by the Investor from the sale of Registrable Securities included in such registration exceeds (ii) the amount of any other losses, expenses, settlements, damages, claims and liabilities that the Investor has been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission or violation. No person guilty of fraudulent misrepresentation (within the meaning of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

5.1.5

Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in an underwriting agreement entered into in connection with an underwritten public offering are in conflict with the foregoing provisions, the provisions in such underwriting agreement shall control.

The parties shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

6.7
