(v) Deferral. If (A) in the good faith judgment of the Board of Directors of the Company (excluding any interested directors), the filing of a registration statement under this Section 2(b) covering the Registrable Securities would be materially detrimental to the Company and the Board of Directors of the Company (excluding any interested directors) concludes, as a result, that it is in the best interests of the Company to defer the filing of such registration statement at such time, and (B) the Company shall furnish to such Buyers a certificate signed by the Chief Executive Officer or the Chief Financial Officer of the Company stating that in the good faith judgment of the Board of Directors of the Company (excluding any interested directors), it would be materially detrimental to the Company for such registration statement to be filed in the near future and that it is, therefore, in the best interests of the Company to defer the filing of such registration statement, then the Company shall have the right to defer such filing for a period of not more than forty-five (45) days beyond the Filing Deadline, and, provided further, that the Company shall not defer its obligation in this manner more than once in any twelve (12) month period; provided that this Section 2(a)(v) shall become null and void immediately upon an Event of Default (as defined in the Note).

(b) Demand Registration Rights.

(i) Generally. Subject to the conditions set forth in this Section 2(b), if, at any time after the Filing Deadline and prior to the expiration of the Effectiveness Period (as defined in Section 4(a) below), (x) a Registration Statement covering the sale of all of the Registrable Securities is not then effective and available for sales thereof by the Buyers, and (y) the Company shall receive from any Buyer or Buyers holding at least 25% of the Registrable Securities (the “Initiating Buyers”) a written request signed by such Initiating Buyers that the Company effect a registration with respect to all or a part of the Registrable Securities (which request shall state the number of shares of Registrable Securities to be disposed of and the intended methods of disposition of such shares by such Initiating Buyers), the Company will:

(A) promptly (but in case more than ten (10) Business Days after receipt of such request) give written notice of the proposed registration to all other Buyers; and

4

(B) as soon as practicable, file and use its commercially reasonable efforts to effect such registration (including, without limitation, filing post-effective amendments, appropriate qualifications under applicable U.S. blue sky or other state securities laws, and appropriate compliance with the Securities Act) and to permit or facilitate the sale and distribution of all or such portion of such Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any Buyer or Buyers joining in such request as are specified in a written request received by the Company within ten (10) days after such written notice from the Company is mailed or delivered.

(ii) Limitations. The Company shall not be obligated to effect, or to take any action to effect, any such registration pursuant to this Section 2(b):

(A) If the Initiating Buyers, together with the holders of any other securities of the Company entitled to inclusion in such registration statement (the “Other Holders”), propose to sell Registrable Securities and such other securities (if any) at an aggregate offering price (after deduction of underwriters’ discounts and expenses related to issuance) of less than U.S.$10,000,000;

(B) After the Company has initiated two (2) such registrations pursuant to this Section 2(b) (counting for these purposes only (I) registrations which have been declared or ordered effective and pursuant to which securities have been sold, and (II) a demand registration right under this Section 2(b) that the Buyers have affirmatively forfeited; or

(C) During the period starting with the date sixty (60) days prior to the Company’s good faith estimate of the date of filing of, and ending on a date one hundred eighty (180) days after the effective date of, a Company-initiated registration; provided that the Company is actively employing in good faith commercially reasonable efforts to cause such registration statement to become effective.

(iii) Deferral. If (A) in the good faith judgment of the Board of Directors of the Company (excluding any interested directors), the filing of a registration statement under this Section 2(b) covering the Registrable Securities would be materially detrimental to the Company and the Board of Directors of the Company (excluding any interested directors) concludes, as a result, that it is in the best interests of the Company to defer the filing of such registration statement at such time, and (B) the Company shall furnish to such Buyers a certificate signed by the Chief Executive Officer or the Chief Financial Officer of the Company stating that in the good faith judgment of the Board of Directors of the Company (excluding any interested directors), it would be materially detrimental to the Company for such registration statement to be filed in the near future and that it is, therefore, in the best interests of the Company to defer the filing of such registration statement, then (in addition to the limitations set forth in Section 2(b)(ii) above) 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 of the Initiating Buyers, and, provided further, that the Company shall not defer its obligation in this manner more than twice in any twelve (12) month period.

(iv) Other Shares. The registration statement filed pursuant to the request of the Initiating Buyers may, subject to the provisions of Section 2(b)(v) below, include (A) securities of the Company being sold for the account of the Company and (B) shares of Common Stock with respect to which the Company has, prior to the date hereof, granted registration rights (“Other Shares”) pursuant to the ABN Registration Rights Agreement and the 2007 Registration Rights Agreement (such rights, “Existing Registration Rights”).

(v) Underwriting.

(A) If the Initiating Buyers intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to this Section 2(b) and the Company shall include such information in the written notice given pursuant to Section 2(b)(i)(A). In such event, the right of any Buyer to include all or any portion of its Registrable Securities in such registration pursuant to this Section 2(b) shall be conditioned upon such Buyer’s participation in such underwriting and the inclusion of such Buyer’s Registrable Securities to the extent provided herein. If the Company shall request inclusion in any registration pursuant to this Section 2(b) of securities being sold for its own account, or if holders of Other Shares shall request inclusion in any registration pursuant to this Section 2(b), the Initiating Buyers shall, on behalf of all Buyers, offer to include such securities in the underwriting and such offer shall be conditioned upon the participation of the Company or such other persons in such underwriting and the inclusion of the Company’s and such Other Holders’ other securities of the Company and their acceptance of the further applicable provisions of this Section 2. The Company shall (together with all Buyers and Other Holders proposing to distribute their securities through such underwriting) enter into an underwriting agreement in customary form with the representative of the underwriter or underwriters selected for such underwriting by the Company, which underwriters are reasonably acceptable to a majority in interest of the Initiating Buyers.

(B) Notwithstanding any other provision of this Section 2(b), if the underwriters advise the Initiating Buyers in writing that marketing factors require a limitation on the number of shares to be underwritten, the number of Registrable Securities and Other Shares that may be so included shall be allocated as follows: (I) first, among all Buyers requesting to include Registrable Securities in such registration statement based on the pro rata percentage of Registrable Securities held by such Buyers; (II) second, to holders of Other Shares electing to register shares in connection with such registration; and (III) third, to the Company, which the Company may allocate, at its discretion, for its own account, or for the account of Other Holders or employees of the Company.

(C) If a person who has requested inclusion in a registration pursuant to this Section 2(b) does not agree to the terms of any underwriting in accordance with this Section 2(b)(v), such person shall be excluded from the underwriting by written notice from the Company, the underwriter or the Initiating Buyers. The securities so excluded shall also be withdrawn from registration. If shares are so withdrawn from the registration and if the number of shares to be included in such registration was previously reduced as a result of marketing factors pursuant to Section 2(b)(v)(B) above, then the Company shall then offer to all Buyers and holders of Other Shares who have elected to include and retained rights to include securities in the registration the right to include additional Registrable Securities or Other Shares, as applicable, in the registration in an aggregate amount equal to the number of shares so withdrawn, with such shares to be allocated among such Buyers and Other Holders requesting additional inclusion, in order of priority as set forth in Section 2(b)(v)(B) above.

6

(c) Piggyback Registration Rights.

(i) Generally. If, at any time after the Filing Deadline and prior to the expiration of the Effectiveness Period (as defined in Section 4(a) below), (i) the Company proposes to register shares of Common Stock under the Securities Act in connection with the public offering of such shares for cash other than a registration statement on Form S-8 or Form S-4 or any successor or other forms promulgated for similar purposes (a “Proposed Registration”) and (ii) a Registration Statement covering the sale of all of the Registrable Securities is not then effective and available for sales thereof by the Buyers, the Company shall, at such time, promptly give each Buyer written notice of such Proposed Registration. Each Buyer shall have ten (10) Business Days from its receipt of such notice to deliver to the Company a written request specifying the amount of Registrable Securities that such Buyer intends to sell and such Buyer’s intended method of distribution. Upon receipt of such request, the Company shall use its best efforts to cause all Registrable Securities which the Company has been requested to register to be registered under the Securities Act to the extent necessary to permit their sale or other disposition in accordance with the intended methods of distribution specified in the request of such Buyer; provided, however, that the Company shall have the right to postpone or withdraw any registration effected pursuant to this Section 2(c) without obligation to the Buyers.

(ii) Underwriting.

(A) If the Registration of which the Company gives notice is for a registered public offering involving an underwriting, the Company shall so advise each of the Buyers as part of the written notice given pursuant to 2(c)(i). In such event, the right of any Buyer to include all or any portion of its Registrable Securities in such registration pursuant to this Section 2(c) shall be conditioned upon such Buyer’s participation in such underwriting and the inclusion of such Buyer’s Registrable Securities to the extent provided herein. If a Buyer shall request inclusion in any registration pursuant to this Section 2(c) of its Registrable Securities, the Company shall offer to include such securities in the underwriting and such offer shall be conditioned upon the participation of such Buyer and the inclusion of such Buyer’s Registrable Securities and their acceptance of the further applicable provisions of this Section 2(c). A Buyer whose shares are to be included in such Registration shall (together with all Buyers and Other Holders proposing to distribute their securities through such underwriting) enter into an underwriting agreement in customary form with the representative of the underwriter or underwriters selected for such underwriting by the Company.

(B) Notwithstanding any other provision of this Section 2(c), if the underwriters advise the Company in writing that marketing factors require a limitation on the number of shares to be underwritten, the Company shall be obligated to include in the registration statement only such limited portion of the Registrable Securities with respect to which each Buyer has requested inclusion hereunder as such underwriter(s) shall permit. Any exclusion of Registrable Securities shall be made pro rata among the Buyers seeking to include Registrable Securities in a registration statement, in proportion to the number of Registrable Securities sought

7

to be included by such Buyers; 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 to inclusion of such securities in the registration statement or are not entitled to pro rata inclusion with the Registrable Securities; and provided, further, that, after giving effect to the immediately preceding provision, any exclusion of Registrable Securities shall be made pro rata with holders of other securities underlying Existing Registration Rights who have elected to include such securities in the registration statement

(C) If a person who has requested inclusion in a registration pursuant to this Section 2(c) does not agree to the terms of any underwriting in accordance with this Section 2(c)(ii), such person shall be excluded from the underwriting by written notice from the Company or the underwriter. The securities so excluded shall also be withdrawn from registration. If shares are so withdrawn from the registration and if the number of shares to be included in such registration was previously reduced as a result of marketing factors pursuant to Section 2(c)(ii)(B) above, then the Company shall then offer to all Buyers and holders of Other Shares who have elected to include and retained rights to include securities in the registration the right to include additional Registrable Securities or Other Shares, as applicable, in the registration in an aggregate amount equal to the number of shares so withdrawn, with such shares to be allocated among such Buyers and Other Holders requesting additional inclusion, in order of priority as set forth in Section 2(c)(ii)(B) above.

(d) Expenses. The Issuer will pay all expenses associated with each registration, including filing and printing fees, the Company’s counsel and accounting fees and expenses, costs associated with clearing the Registrable Securities for sale under applicable state securities laws and listing fees, but excluding fees and expenses of counsel to the Buyers, discounts, commissions, fees of underwriters, selling brokers, dealer managers or similar securities industry professionals with respect to the Registrable Securities being sold, provided that the Issuer shall pay the reasonable fees and expenses, not to exceed U.S.$10,000 in the aggregate, of one counsel for the Buyers.

(e) Conversion From Form S-1 to Form S-3. In the event any Registration Statement covering Registrable Securities is on a Form S-1, the Company shall convert each such Registration Statement into a registration statement on Form S-3 within 30 days of the Company becoming eligible to file a registration statement on Form S-3.

(a) Subject to Section 3(b) below, in the event: (i) of any request by the SEC or any other federal or state governmental authority during the period of effectiveness of the Registration Statement for amendments or supplements to the Registration Statement or related prospectus or for additional information so that the Registration Statement will not contain an 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 or otherwise fail to comply with the applicable rules and regulations of the federal securities laws; (ii) of the issuance by the SEC or any other federal or state governmental authority of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose; (iii) of the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for resale in any jurisdiction or the initiation of

8

any proceeding for such purpose, provided that, considering the advice of counsel, the Company reasonably believes that it must qualify in such jurisdiction; (iv) of any event or circumstance that, considering the advice of counsel, the Company reasonably believes necessitates the making of any changes in the Registration Statement or related prospectus, or any document incorporated or deemed to be incorporated therein by reference, so that, in the case of the Registration Statement, it will not contain any untrue statement of a material fact or any omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and that in the case of a related prospectus, it will not contain any untrue statement of a material fact or any omission to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; or (v) that the Company reasonably believes, considering the advice of counsel, that the Company may, in the absence of a suspension described hereunder, be required under state or federal securities laws to disclose any corporate development, the disclosure of which could reasonably be expected to have a material adverse effect upon the Company, its stockholders, a potentially material transaction or event involving the Company, or any negotiations, discussions or proposals directly relating thereto; then the Company shall deliver a certificate in writing (the “Suspension Notice”) to each holder of Registrable Securities (the “Holder”) to the effect of the foregoing (but in no event, without the prior written consent of a Buyer, shall the Company disclose to such Buyer any of the facts or circumstances regarding any material nonpublic information) and, upon receipt of such Suspension Notice, the Holder will refrain from selling any Registrable Securities pursuant to the Registration Statement (a “Suspension”) until the Holder’s receipt of copies of a supplemented or amended prospectus prepared and filed by the Company or until the Holder is advised in writing by the Company that the current prospectus may be used and the Holder has received copies of any additional or supplemental filings that are incorporated or deemed incorporated by reference in any such prospectus.

(b) Notwithstanding the foregoing, the Company shall not suspend any Registration Statement or related prospectus for more than forty-five (45) consecutive days or for a total of more than ninety (90) days in any twelve (12) month period (each a “Permitted Suspension” and together the “Permitted Suspensions”).

(c) The Company will use commercially reasonable efforts to terminate a Suspension as promptly as practicable after delivery of a Suspension Notice to the Holders.

(m) if, after the Initial Exchange Date, a Buyer believes, after consultation with its counsel, that it could reasonably be deemed to be an underwriter of Registrable Securities, or if any Buyer intends to distribute the Registrable Securities covered by means of an underwriting, at the request of such Buyer, the Company shall (i) cause to be prepared and shall furnish to such Buyer or underwriter, on the date of the effectiveness of a Registration Statement and thereafter from time to time on such dated as such Buyer or underwriter may reasonably request (A) a customary “comfort letter”, dated as of such date, from the Company’s independent certified public accountants to underwriters in an underwritten public offering, addressed to such Buyer or underwriters, and (B) an opinion, dated as of such date, of legal counsel representing the Company for purposes of such Registration Statement, in form, scope and substance as is customarily given in an underwritten public offering, addressed to such Buyer or underwriters, (ii) make available by such Buyer or underwriters, their legal counsel and one firm of accountants or other agents retained by such Buyer or underwriters (collectively, the “Inspectors”) during regular business hours and upon reasonable notice, all pertinent financial and other records, and pertinent corporate documents and properties of the Company (collectively, the “Records”), as shall be reasonably deemed necessary or appropriate by each Inspector, and cause the Company’s officers, directors and employees to supply all information which any Inspector may reasonably request; provided, however, that each Inspector shall agree to hold in strict confidence and shall not make any disclosure (except to such Buyer or underwriters and the other Inspectors) or use of any Record or other information which the Company determines in good faith to be confidential, and of which determination the Inspectors are so notified, unless (x) the disclosure of such Records is necessary to avoid or correct a misstatement or omission in any Registration Statement or is otherwise required under the Securities Act, (y) ordered by a court of competent jurisdiction or (z) the information in such Records has been made generally available to the public other than by disclosure in violation of this Agreement, and (iii) in the event of an underwritten offering, enter into an underwriting agreement in customary form with the representative of the underwriter. Nothing herein (or in any other confidentiality agreement between the Company and any Buyer) shall be deemed to limit any Buyer’s ability to sell Registrable Securities in a manner which is otherwise consistent with applicable laws and regulations; and

(n) if requested by a Buyer, the Company shall, as soon as practicable (i) incorporate in a prospectus supplement or post-effective amendment such information as a Buyer reasonably requests to be included therein relating to the sale and distribution of Registrable Securities, including, without limitation, information with respect to the number of Registrable Securities being offered or

12

sold, the purchase price being paid therefor and any other terms of the offering of the Registrable Securities to be sold in such offering, (ii) make all required filings of such prospectus supplement or post-effective amendment and (iii) supplement or make amendments to any Registration Statement if reasonably requested by a Buyer holding any Registrable Securities.

(a) Each Buyer shall furnish in writing 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 required to effect the registration of such Registrable Securities and as shall be necessary so that the Registration Statement, the Prospectus or any preliminary prospectus or similar offering document shall not include any untrue statement or alleged untrue statement of a material fact or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, and shall promptly notify the Company if any such previously provided information shall contain or omit any such information. Each Buyer shall also execute such documents in connection with such registration as the Company may reasonably request. At least five (5) Business Days prior to the first anticipated filing date of any Registration Statement, the Company shall notify each Buyer of the information the Company requires from such Buyer if such Buyer elects to have any of the Registrable Securities included in the Registration Statement. A Buyer shall provide such information to the Company at least two (2) Business Days prior to the first anticipated filing date of such Registration Statement if such Buyer elects to have any of the Registrable Securities included in the Registration Statement.

(b) Each Buyer, by its 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 a Registration Statement hereunder, unless such Buyer has notified the Company in writing of its election to exclude all of its Registrable Securities from such Registration Statement.

(c) Each Buyer agrees that, upon receipt of any notice from the Company of the commencement of a Suspension pursuant to Section 3, such Buyer will immediately discontinue disposition of Registrable Securities pursuant to the Registration Statement covering such Registrable Securities, until the Buyer’s receipt of the supplemented or amended prospectus filed with the SEC and until any related post-effective amendment is declared effective and, if so directed by the Company, the Buyer shall deliver to the Company (at the expense of the Company) or destroy (and deliver to the Company a certificate of destruction) all copies in the Buyer’s possession of the Prospectus covering the Registrable Securities current at the time of receipt of such notice.

(a) Indemnification by the Company and the Issuer. The Issuer agrees to indemnify and hold harmless, to the fullest extent permitted by law, the Buyers and their respective directors, managers, officers, employees, stockholders, members, and each Person who controls any Buyer (within the meaning of the Securities Act) against any losses, claims, damages, judgments, amounts paid in settlement, liabilities and expenses (including, without limitation, reasonable attorneys’ fees) resulting from or which arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact in any Registration Statement or any

13

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 of a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) any untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus if used prior to the effective date of such Registration Statement or contained in the final prospectus (as amended or supplemented) 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 (any of the foregoing, a “Violation”), and will reimburse each Buyer and their respective directors, managers, members, officers, employees, stockholders or controlling Persons for any legal and other expenses reasonably incurred as such expenses are reasonably incurred by such Person in connection with investigating, defending, settling, compromising or paying any such Violation; provided, however, that the Issuer will not be liable in any such case if and to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished in writing by a Buyer specifically for use in such Registration Statement or Prospectus or any other offering document.

(b) Indemnification by the Buyers. Each Buyer agrees, severally and jointly, to indemnify and hold harmless, to the fullest extent permitted by law, the Company, its directors, officers, employees, stockholders and each Person who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages, judgments, amounts paid in settlement, liabilities and expenses (including, without limitation, reasonable attorneys’ fees) resulting from or which arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact or any omission or alleged omission of a material fact required to be stated in the Registration Statement or Prospectus or preliminary prospectus or amendment or supplement thereto or necessary to make the statements therein not misleading, to the extent, but only to the extent that such untrue statement or omission or alleged statement or omission is contained in any information furnished in writing by such Buyer to the Company specifically for inclusion in such Registration Statement or Prospectus or amendment or supplement thereto, and (ii) any inaccuracy in the representations and warranties of the Buyer contained in this Agreement, and will reimburse the Company, and its directors, officers, employees, stockholders or controlling Persons for any legal and other expenses reasonably incurred as such expenses are reasonably incurred by such Person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. In no event shall the liability of a Buyer be greater in amount than the dollar amount of the proceeds (net of all expenses paid by such Buyer in connection with any claim relating to this Section 6 and the amount of any damages such Buyer has otherwise been required to pay by reason of such untrue statement or omission or alleged untrue statement or omission) received by such Buyer upon the sale of the Registrable Securities included in the Registration Statement giving rise to such indemnification obligation.

(c) Conduct of Indemnification Proceedings. Any Person entitled to indemnification hereunder shall (i) give prompt notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party; provided that any Person entitled to indemnification hereunder shall have the right to employ separate counsel and to participate in the defense of such claim, but the fees

14

and expenses of such counsel shall be at the expense of such Person unless (a) the indemnifying party has agreed to pay such fees or expenses, or (b) the indemnifying party shall have failed to assume the defense of such claim within five (5) Business Days after written notice thereof and employ counsel reasonably satisfactory to such Person or (c) in the reasonable judgment of any such Person, considering the advice of counsel, a conflict of interest exists between such Person and the indemnifying party with respect to such claims (in which case, if the Person notifies the indemnifying party in writing that such Person elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of such claim on behalf of such Person); and provided, further, that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations hereunder, except to the extent that such failure to give notice shall materially adversely affect the indemnifying party in the defense of any such claim or litigation. It is understood that the indemnifying party shall not, in connection with any proceeding in the same jurisdiction, be liable for fees or expenses of more than one additional firm of attorneys at any time for all such indemnified parties. No indemnifying party will, except with the consent of the indemnified party, consent to entry of any judgment or enter into any settlement that 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 of such claim or litigation.

(d) Contribution. If for any reason the indemnification provided for in the preceding paragraphs (a) and (b) is unavailable to an indemnified party or insufficient to hold it harmless, other than as expressly specified therein, then the indemnifying party shall contribute to the amount paid or payable by the indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnified party and the indemnifying party, as well as any other relevant equitable considerations. No Person guilty of fraudulent misrepresentation within the meaning of Section 11(f) of the Securities Act shall be entitled to contribution from any Person not guilty of such fraudulent misrepresentation. In no event shall the contribution obligation of a Buyer be greater in amount than the dollar amount of the proceeds (net of all expense paid by such Buyer in connection with any claim relating to this Section 6 and the amount of any damages such Buyer has otherwise been required to pay by reason of such untrue statement or omission or alleged untrue statement or omission) received by such Buyer upon the sale of the Registrable Securities included in the Registration Statement giving rise to such contribution obligation.

(a) Amendments and Waivers. This Agreement may be amended only by a writing signed by the Company and the Required Buyers, provided that any such amendment shall not disproportionately affect the rights of any Buyer, relative to all other Buyers, without the consent of such Buyer. The Company may take any action herein prohibited, or omit to perform any act herein required to be performed by it, only if the Company shall have obtained the written consent to such amendment, action or omission to act, of the Required Buyers.

(b) Notices. All notices and other communications provided for or permitted hereunder shall be made as set forth in Section 9(f) of the Purchase Agreement.

(c) Assignments and Transfers by Buyers. The provisions of this Agreement shall be binding upon and inure to the benefit of the Buyers and their respective successors and permitted assigns. A Buyer may transfer or assign, in whole or from time to time in part, to one or more Persons its rights hereunder to whom such Buyer transfers the Registrable Securities in compliance with Section 12 of the Note and Section 9(g) of the Purchase Agreement, provided that such Buyer complies with all laws applicable thereto and provides written notice of assignment to the Company promptly after such assignment is effected.

(d) Assignments and Transfers by the Company. This Agreement may not be assigned by the Company or the Issuer without the prior written consent of the Required Buyers, provided, however, that the Company and the Issuer may assign their respective rights and delegate their respective duties hereunder to any surviving or successor corporation in connection with a merger or consolidation of the Company or the Issuer, as applicable, with another corporation, or a sale, transfer or other disposition of all or substantially all of the Company or the Issuer’s assets, as applicable, to another corporation, without the prior written consent of the Required Buyers, after notice duly given by the Company or Issuer, as applicable, to each Buyer.

(f) Counterparts; Faxes. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. This Agreement may also be executed via facsimile, which shall be deemed an original.

(g) Titles and Subtitles. The titles and subtitles used in this Agreement are used for convenience only and are not to be considered in construing or interpreting this Agreement.

(h) Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof but shall be interpreted as if it were written so as to be enforceable to the maximum extent permitted by applicable law, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. To the extent permitted by applicable law, the Parties hereby waive any provision of law which renders any provisions hereof prohibited or unenforceable in any respect.

(i) Further Assurances. The Parties shall execute and deliver all such further instruments and documents and take all such other actions as may reasonably be required to carry out the transactions contemplated hereby and to evidence the fulfillment of the agreements herein contained.

(l) Governing Law; Jurisdiction; Jury Trial. All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by the internal laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State 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, 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 brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper. 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 to such party at the address for such notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. The Company hereby appoints CT Corporation System, with offices at 111 Eighth Avenue, New York, NY 10011, as its agent for service of process in New York.
