     3. Registration Rights.

     (a) Effectiveness Deadline. The Company shall (i) within 45 days after the Closing Date, file with the Securities and Exchange Commission (the “SEC”) a shelf-registration statement under the Securities Act (x) under which the Offering Holders (as defined below) may sell Offering Shares (as defined below) (y) that registers Offering Shares that are shares of Common Stock in an amount that is no less than 130% of the number of shares of Common Stock issuable upon the conversion of all of the then outstanding shares of Series A Preferred Stock or Series C Preferred Stock whether or nor such shares are then convertible, (ii) use its reasonable best efforts to have such registration statement declared effective within 120 days after the Closing Date, and (iii) at all times until the Registration Termination Date (as defined below), the Company shall maintain an effective shelf-registration statement (x) under which the Offering Holders may sell Offering Shares that are shares of Common Stock, (y) if the Shares or Alternate Preferred Stock are then convertible or have been converted into New Preferred Stock Units, under which the Offering Holders may sell Offering Shares that are New Preferred Stock Units, and (z) that covers a number of shares of Common Stock that is no less than (a) 130% of the number of Unissued Offering Shares that are shares of Common Stock plus the number of Outstanding Offering Shares that are shares of Common Stock and (b) if the Shares or Alternate Preferred Stock are then convertible or have been converted into New Preferred Stock Units, 130% of the number of the Unissued Offering Shares that are New Preferred Stock Units plus the number of Outstanding Offering Shares that are New Preferred Stock Units. As used herein, “Offering Shares” means, as of any time, (a) shares of Common Stock or New Preferred Stock Units previously issued upon conversion of the Shares, Alternate Preferred Stock or New Preferred Stock Units or as a dividend or redemption payment in respect of, the Shares or Alternate Preferred Stock and not previously sold pursuant to an effective registration statement under the Securities Act or in a brokers’ transaction (as defined in Rule 144(g) promulgated under the Securities Act) (the “Outstanding Offering Shares”), and (b) shares of Common Stock then issuable upon conversion of the then outstanding Shares, Alternate Preferred Stock or New Preferred Stock Units (assuming for this purpose, that all such outstanding Shares, Alternate Preferred Stock or New Preferred Stock Units are fully converted, whether or not then convertible, and that any Stockholder Approval required for the issuance of such shares or units

has been obtained) and New Preferred Stock Units then issuable upon conversion of the then outstanding Shares or Alternate Preferred Stock (the “Unissued Offering Shares”). The Investors (so long as they hold any Shares, Alternate Preferred Stock, New Preferred Stock Units or Offering Shares), together with their Affiliates (as defined below), and any Persons who hold any Shares, Alternate Preferred Stock, New Preferred Stock Units or Offering Shares acquired from any Offering Holder are hereafter referred to as “Offering Holders.” The Company agrees that no Person other than Offering Holders shall be permitted to sell shares of Common Stock or other securities pursuant to the shelf registration statement contemplated hereby. The Company will include in any registration statement filed or maintained by the Company pursuant to this Section 3(a) (i) the information required under the Securities Act to be so included concerning the Offering Holders, as provided by the Investors on the signature page hereto, including any changes in such information or other information that may be provided by the Offering Holders in writing to the Company from time to time, and (ii) a section entitled “Plan of Distribution,” substantially in the form of Exhibit D hereto with such additions thereto as may be requested by an Offering Holder, that describes the various procedures that may be used by the Offering Holders in the sale of Offering Shares. As used herein, the term “Registration Termination Date” means the first date after the first anniversary of the Closing upon which (x) the number of Offering Shares is less than two percent (2%) of the number of shares of Common Stock then outstanding and (b) no Offering Holder and its Affiliates holds Offering Shares that represent more than one percent (1%) of the number of shares of Common Stock outstanding unless all such Offering Shares are then eligible for resale under Rule 144(k) promulgated under the Securities Act, and the term “Transaction Documents” means this Agreement, the Certificate, Series C Certificate and the New Preferred Stock Units Certificate.

     (b) Failure to Meet Effectiveness Deadline. In addition to any other rights or remedies provided herein, if the registration statement referred to in Section 3(a) above has not been filed with the SEC within 45 days after the Closing Date, declared effective by the SEC within 120 days after the Closing Date or the Company fails to maintain the effectiveness of such registration statement pursuant to the terms contained in Section 4(d) of the Certificate, then the Company shall pay an increased dividend rate on the Shares in accordance with the Certificate or the Series C Certificate, as applicable. Payment of such increased dividend rate by the Company shall be in addition to, and shall not limit, the other remedies available to the Investors in the event that the Company does not comply with this Section 3 with respect to the filing and effectiveness of the registration statement referred to herein.

     (c) Delay Rights. Notwithstanding any other provision of this Section 3, the Company may, upon written notice (such notice a “Delay Notice”) to any Offering Holder whose Offering Shares are included in the registration statement, voluntarily suspend the effectiveness of any such registration statement for a limited time, which suspension shall in no event be longer than twenty-five (25) days in any three-month period, and no longer than sixty (60) days in any twelve-month period, if (i) the Company has been advised by counsel or underwriters to the Company that the offering of any Offering Shares pursuant to the registration statement would materially adversely affect, or would be improper in view of (or improper without disclosure in a prospectus) a proposed financing, a reorganization, recapitalization, merger, consolidation or similar transaction involving the Company or (ii) if at any time the prospectus included in such registration statement includes an untrue statement of material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in

light of circumstances then existing. Upon receipt of a Delay Notice, the Offering Holder shall immediately suspend any and all sales of the Offering Shares until such time as the Company notifies the Offering Holder that such suspension has been terminated and the registration statement is again in effect with respect to the Offering Shares (such notice, an “Effective Notice”). Upon disclosure of such information or the termination of the condition described above, the Company shall provide prompt notice to the Offering Holders whose Offering Shares are included in the registration statement, and shall promptly terminate any suspension of sales it has put into effect and shall take such other actions to permit registered sales of registrable securities as contemplated in this Agreement. Notwithstanding any provision contained herein to the contrary, the Company’s obligation to include, or continue to include, Offering Shares in any such registration statement under this Section 3 shall continue until the Registration Termination Date.

     (d) Underwritten Offering.

     (i) Underwriting. Any Offering Holder or Offering Holders may at any time request the ability (each a “Requesting Offering Holder”) to dispose of Offering Shares under the registration statement pursuant to an underwritten offering by delivering to the Company a notice setting forth such request (an “Underwriting Request”) and the number of Offering Shares sought to be disposed of by such Requesting Offering Holder in such underwritten offering. Within two (2) Business Days of the Company’s receipt of an Underwriting Request, the Company shall deliver a notice (an “Underwriting Notice”) to the Offering Holders other than the Requesting Offering Holder(s) (such other Offering Holders, the “Additional Offering Holders”) notifying such Additional Offering Holders of such Underwriting Request. Each of the Additional Offering Holders shall have the right, exercisable by delivery of a notice (a “Piggy-Back Notice”) to the Company and to the Requesting Offering Holder within five (5) Business Days of receipt of the Underwriting Notice, to elect to dispose of Offering Shares in the underwritten offering. Each Piggy-Back Notice shall set forth the number of Offering Shares the applicable Additional Offering Holder desires to dispose of in the underwritten offering. Each of the Requesting Offering Holders and Additional Offering Holders shall be entitled to dispose in the underwritten offering of the number of Offering Shares set forth in its Underwriting Request or Piggy-Back Notice, as applicable, provided, however, that if the Managing Underwriters (as defined below) advise the Offering Holders that the number of Offering Shares to be sold in the underwritten offering is greater than the number of Offering Shares which can be offered in an orderly manner in such offering within a price range acceptable to a holders of a majority of the Offering Shares sought to be disposed of in the underwritten offering and without adversely affecting the marketability of the offering (the “Offering Number”), no securities other than Offering Shares shall be offered in such underwriting and the number of Offering Shares to be offered in the offering shall be reduced pro rata based on the number of Offering Shares sought to be included in the offering by the Requesting Offering Holders and the Additional Offering Holders to the extent necessary so that the aggregate number of Offering Shares offered in such offering is no greater than the Offering Number. As promptly as practicable after the expiration of the five (5) Business Day period for delivery of Piggy-Back Notices, the Company shall, at the request of such Offering Holder(s), enter into an underwriting agreement in customary form with the book-running lead manager of such underwritten

offering (the “Managing Underwriter” or “Underwriters”), which shall include, among other provisions, indemnities to the effect and to the extent provided in Section 9, and shall take all such other actions as the Offering Holders or the Managing Underwriter or Underwriters participating in such offering and sale may reasonably request in order to expedite or facilitate such offering and sale (other than such actions which are disruptive to the Company or require significant management accountability), including providing reasonable availability of appropriate members of senior management of the Company to provide customary due diligence assistance in connection with any offering and to participate in customary “road show” presentations in connection with any underwritten offerings in substantially the same manner as they would in an underwritten primary registered public offering by the Company of its Common Stock, after taking into account the reasonable business requirements of the Company in determining the scheduling and duration of any road show. Notwithstanding the foregoing, the Company shall not be required to effect an Underwritten Offering unless either the gross proceeds reasonably anticipated from such offering is at least $25 million or the number of Offering Shares sought to be sold is no less than ten percent (10%) of the number of the outstanding shares of Common Stock of the Company.

     (ii) General Procedures. In connection with any underwritten offering under this Agreement, the Company shall be entitled to select the Managing Underwriter or Underwriters. In connection with an underwritten offering, each Offering Holder desiring to dispose of Offering Shares in the underwritten offering and the Company shall be obligated to enter into an underwriting agreement that contains such representations, covenants, indemnities and other rights and obligations as are customary in underwriting agreements for firm commitment offerings of securities. No Offering Holder may participate in such underwritten offering unless such Offering Holder agrees to sell its Offering Shares on the basis provided in such underwriting agreement and completes and executes all questionnaires, powers of attorney, indemnities and other documents reasonably required under the terms of such underwriting agreement. Each Offering Holder may, at its option, require that any or all of the representations and warranties by, and the other agreements on the part of, the Company to and for the benefit of such underwriters also be made to and for such Offering Holder’s benefit (with respect to the Offering Shares of such Offering Holder being sold in such underwritten offering) and that any or all of the conditions precedent to the obligations of such underwriters under such underwriting agreement also be conditions precedent to its obligations. No Offering Holder shall be required to make any representations or warranties to or agreements with the Company or the underwriters other than representations, warranties or agreements regarding such Offering Holder and its ownership of the securities being registered on its behalf and its intended method of distribution and any other representation required by law. If any Offering Holder disapproves of the terms of an underwriting, such Offering Holder may elect to withdraw therefrom by notice to the Company and the Managing Underwriter.

     (e) Sale Procedures. In connection with the registration of the Offering Shares under the Securities Act for the account of an Offering Holder, the Company will:

     (i) prepare and file with the SEC a registration statement with respect to such securities as indicated above;

     (ii) prepare and file with the SEC such amendments and supplements to such registration statement and/or the prospectus used in connection therewith as may be necessary to keep such registration statement effective and to comply with the requirements of the Securities Act and the rules and regulations promulgated by the SEC thereunder relating to the sale or other disposition of all securities covered by such registration statement and to allow for the sale of Offering Shares by the Offering Holders pursuant to the method of distribution, requested by any such Offering Holders;

     (iv) if applicable, register or qualify the Offering Shares covered by the registration statement or any other registration statement contemplated by this Agreement under the securities or “blue sky” laws of such jurisdictions as the Offering Holders or, in the case of an underwritten offering, the Managing Underwriter, shall reasonably request; provided, however, that the Company will not be required to qualify generally to transact business in any jurisdiction where it is not then required to so qualify or to take any action which would subject it to general service of process in any such jurisdiction where it is not then so subject;

     (v) promptly notify each Offering Holder and each Managing Underwriter, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of (y) the filing of the registration statement or any other registration statement contemplated by this Agreement or any prospectus or prospectus supplement to be used in connection therewith, or any amendment or supplement thereto or any free writing prospectus related thereto, and, with respect to such registration statement or any other registration statement or any post-effective amendment thereto, when the same has become effective; and (z) any written comments from the SEC with respect to any filing

referred to in clause (y) and any written request by the SEC for amendments or supplements to the registration statement or any other registration statement or any prospectus or prospectus supplement thereto or any free writing prospectus related thereto;

Following the provision of such notice, the Company agrees to as promptly as practicable amend or supplement the prospectus or prospectus supplement or free writing prospectus or take other appropriate action so that the prospectus or prospectus supplement or free writing prospectus does not include 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 in the light of the circumstances then existing and to take such other action as is necessary to remove a stop order, suspension, threat thereof or proceedings related thereto;

     (vii) upon request and subject to appropriate confidentiality obligations, furnish to each Offering Holder copies of any and all transmittal letters or other correspondence with the SEC or any other governmental agency or self-regulatory body or other body having jurisdiction (including any domestic or foreign securities exchange) relating to such offering of Offering Shares;

underwritten offerings of securities and such other matters as the Offering Holder may reasonably request;

     (ix) otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of the SEC, and make available to its security holders, as soon as reasonably practicable, an earnings statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 promulgated thereunder;

     (x) make available to the appropriate representatives of the Managing Underwriter and Offering Holders access to such information and Company personnel as is reasonable and customary to enable such parties to establish a due diligence defense under the Securities Act; provided, however, that the Company need not disclose any information to any representative of the Offering Holders unless and until such representative has executed a confidentiality agreement in favor of the Company;

Each Offering Holder, upon receipt of notice from the Company of the happening of any event of the kind described in subsection (vi) of this Section 3(e), shall forthwith discontinue disposition of the Offering Shares until such Offering Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by subsection (vi) of this Section 3(e) or until it is advised in writing by the Company that the use of the prospectus may be resumed, and has received copies of any additional or supplemental filings incorporated by reference in the prospectus, and, if so directed by the Company, such Offering Holder will, or will request the

     4. Representations and Warranties of the Investors. Each Investor, severally as to itself only and not jointly, hereby represents and warrants to the Company as of the date of this Agreement and on the Closing Date as follows:

     (a) Such Investor is acquiring the Shares and any Offering Shares, for its own account, for investment and not with a view to any public distribution or resale (within the meaning of the Securities Act and applicable state securities laws) in violation of any applicable securities laws; provided, however, that by making the representations herein, such Investor does not agree to hold any of the Shares or Offering Shares for any minimum or other specific term and reserves the right to dispose of any of the Shares or Offering Shares at any time in accordance with or pursuant to a registration statement or an exemption under the Securities Act.

     (b) Such Investor understands that (i) the Shares and any Offering Shares (A) have not been registered under the Securities Act or any state securities laws, (B) will be issued in reliance upon an exemption from the registration and prospectus delivery requirements of the Securities Act pursuant to Section 4(2) and/or Regulation D thereof and (C) will be issued in reliance upon exemptions from the registration and prospectus delivery requirements of state securities laws which relate to private offerings, and (ii) the Investor must therefore bear the economic risk of such investment indefinitely unless a subsequent disposition thereof is registered under the Securities Act and applicable state securities laws or is exempt therefrom.

     (c) Such Investor has knowledge, skill and experience in financial, business and investment matters relating to an investment of this type and is capable of evaluating the merits and risks of such investment and protecting such Investor’s interest in connection with the acquisition of the Shares and any Offering Shares.

     (d) Such Investor has been furnished by the Company information (or provided access to information) regarding the business and financial condition of the Company, its expected plans for future business activities, and the merits and risks of an investment in the Shares and any

     (e) Such Investor has been afforded the opportunity to ask questions of and receive answers from the management of the Company concerning the terms and conditions of the proposed transaction.

To the knowledge of the Company, except as specifically disclosed SEC Reports (as defined below), no Person or group of related Persons beneficially owns (as determined pursuant to Rule 13d-3 under the Exchange Act), or has the right to acquire, by agreement with or by obligation binding upon the Company, beneficial ownership in excess of 5% of the outstanding Common Stock, ignoring for such

     6. Covenants.

     (a) Transfer Restrictions. (i) The Investors covenant that the Shares will only be disposed of by the Investors or any of their respective Affiliates pursuant to an effective registration statement under, and in compliance with the requirements of, the Securities Act or pursuant to an available exemption from the registration requirements of the Securities Act, and in compliance with any applicable state securities laws. In connection with any transfer of the Offering Shares other than to an Affiliate of an Investor or pursuant to an effective registration statement or to the Company, or pursuant to Rule 144(k), or pursuant to Rule 144 (if the Investor certifies to the Company that such transfer is pursuant to Rule 144) and except as otherwise set forth herein, the Company shall be permitted to require the transferor to provide to the Company an opinion of counsel selected by the transferor, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration under the Securities Act. Notwithstanding the foregoing, the Company hereby consents to and agrees to register on the books of the Company and with its Transfer Agent, without any such legal opinion, except to the extent that the Transfer Agent requests such legal

opinion, any transfer of Shares or the Offering Shares by an Investor to an Affiliate of such Investor, provided, that, the transferee certifies to the Company that it is an “accredited investor” as defined in Rule 501 of Regulation D under the Securities Act and provided, that, such Affiliate does not request any removal of any existing legends on any certificate evidencing the Shares or Offering Shares. Pursuant to the foregoing, the Investor acknowledges that the certificates representing the Shares or Offering Shares acquired by the Investor shall bear a restrictive legend substantially as follows:

“THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND STATE SECURITIES LAWS, AND MAY NOT BE OFFERED FOR SALE, SOLD, ASSIGNED, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF UNLESS (I) REGISTERED UNDER THE APPLICABLE SECURITIES LAWS (II) SUCH TRANSACTION IS PURSUANT TO RULE 144 UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR (III) AN OPINION OF COUNSEL, WHICH OPINION IS REASONABLY SATISFACTORY TO THE COMPANY, HAS BEEN DELIVERED TO THE COMPANY AND SUCH OPINION STATES THAT THE SHARES MAY BE TRANSFERRED WITHOUT SUCH REGISTRATION.”

     (ii) Certificates evidencing the Shares and the Offering Shares shall not be required to contain such legend or any other legend after (A) the Shares or the Offering Shares are registered for resale under the Securities Act, (B) following any sale of such Shares or the Offering Shares pursuant to Rule 144, (C) if such Shares or Offering Shares are eligible for sale under Rule 144(k), or (D) if such legend is not required under applicable requirements of the Securities Act (including controlling judicial interpretations and pronouncements issued by the Staff of the SEC). The Company shall cause its counsel to issue the legal opinion included in the Irrevocable Transfer Agent Instructions, in the form of Exhibit E (the “Transfer Agent Instructions”), executed by the Company and delivered to and acknowledged in writing by the transfer agent of the Company (the “Transfer Agent”) on the date that the registration statement required pursuant to Section 3 is first declared effective by the SEC (the “Effective Date”). Following the Effective Date or at such earlier time as a legend is no longer required for certain Shares or Offering Shares, the Company will no later than three (3) Trading Days (as defined below) following the delivery by an Investor to the Company or the Transfer Agent of a legended certificate representing such Shares or Offering Shares and an opinion of counsel to the extent required by Section 6(a)(i), deliver or cause to be delivered to such Investor a certificate representing such Shares or Offering Shares that is free from all restrictive and other legends. The Company may not make any notation on its records or give instructions to the Transfer Agent that enlarge the restrictions on transfer set forth in this Section 6. The Company shall ensure that any future Transfer Agent of the Company acknowledges in writing the Transfer Agent Instructions.

     (iii) If the Company shall fail for any reason or for no reason to issue to such holder unlegended certificates within three (3) Trading Days of receipt of documents

If the Closing Bid Price cannot be calculated for a security on a particular date on any of the foregoing bases, the Closing Bid Price of such security on such date shall be the fair market value as mutually determined by the Company and the Investor. For purposes of this Section 6(a)(iii), if the Company and the Investor are unable to reach a determination as to fair market value within five (5) days after the Request Date, the Company and the Investor shall submit the matter to an independent investment banking firm of national reputation mutually acceptable to the Company and the Investor (“Independent Investment Banking Firm”), which shall, within 20 days after such submission, determine and report to the Company and the Investor the fair value determined by the Independent Investment Banking Firm and such determination shall be conclusive and binding on the Company and the Investor.

     (a) Indemnification by the Company. The Company shall, notwithstanding any termination of this Agreement and notwithstanding any other remedy, indemnify, defend, protect and hold harmless each Investor, the stockholders, owners, officers, directors, partners, members, agents, employees and Affiliates of each of them, each Person who controls any such Investor (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the stockholders, owners, officers, directors, partners, members, agents, employees and Affiliates of each such controlling Person, to the fullest extent permitted by applicable law, from and against any and all Losses, promptly as incurred, arising out of or relating to (i) any misrepresentation or breach of any representation or warranty made by the Company in this Agreement or any certificate, including officer’s certificate, contemplated hereby or thereby, (ii) any breach of any covenant, agreement or obligation of the Company contained in this Agreement or any Transaction Document or any certificate, instrument or document contemplated hereby or thereby, (iii) any cause of action, suit or claim brought or made against such Indemnified Party (as defined below) by a third party (including for these purposes a derivative action brought on behalf of the Company), arising out of or resulting from (x) execution and delivery of this Agreement, and the performance or enforcement of the Transaction Documents or any certificate, instrument or document contemplated hereby or thereby, (y) any transaction financed or to be financed in whole or in part, directly or indirectly, with the proceeds of the issuance of the Shares, or (z) the status of Indemnified Party as holder of the Shares, Alternative Preferred Stock or Offering Shares, (iv) any claim for placement agent’s fees, financial advisory fees, or brokers’ commissions (other than for persons engaged by any Investor or its investment advisor) arising out of the issuance of the Shares or Offering Shares pursuant to the Transaction Documents, (v) any untrue or alleged untrue statement of a material fact contained in the registration statement, any prospectus or any form of Company prospectus or in any amendment or supplement thereto, in any Company preliminary prospectus, or any free writing prospectus utilized in connection therewith, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus or form of prospectus or supplement thereto, or

any free writing prospectus, in the light of the circumstances under which they were made) 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 the Offering Shares are offered not misleading, except to the extent, but only to the extent, that (A) such untrue statements, alleged untrue statements, omissions or alleged omissions are based solely upon information regarding such Investor furnished in writing to the Company by such Investor for use therein, or to the extent that such information relates to such Investor or such Investor’s proposed method of distribution of Offering Shares, or (B) in the case of an occurrence of an event of the type specified in Section 3(e)(vi)(y)-(z), the use by such Investor of an outdated or defective prospectus after the Company has notified such Investor in writing that the prospectus is outdated or defective and prior to the receipt by such Investor of the Effective Notice pursuant to Section 3(c), (vi) 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 Offering Shares pursuant to a registration statement, or (vii) any violation of this Agreement. The Company shall notify the Investors promptly of the institution, threat or assertion of any Proceeding of which the Company is aware in connection with the transactions contemplated by the Transaction Documents.

     (b) Indemnification by Investors. Each Investor shall, severally and not jointly, indemnify and hold harmless the Company, its directors, officers, agents and employees, each Person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, agents or employees of such controlling Persons, to the fullest extent permitted by applicable law, from and against all Losses (as determined by a court of competent jurisdiction in a final judgment not subject to appeal or review) arising solely out of any untrue statement of a material fact contained in the registration statement, any prospectus, or any form of prospectus, or in any amendment or supplement thereto, or any free writing prospectus utilized in connection therewith, or arising solely out of any omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus or form of prospectus or supplement thereto, or any free writing prospectus, in the light of the circumstances under which they were made) not misleading to the extent, but only to the extent, that such untrue statement or omission is contained in any information so furnished by such Investor to the Company specifically for inclusion in such registration statement or such prospectus or to the extent that (i) such untrue statements or omissions are based solely upon information regarding such Investor furnished to the Company by such Investor in writing expressly for use therein, or to the extent that such information relates to such Investor or such Investor’s proposed method of distribution of Offering Shares and was reviewed and expressly approved by such Investor expressly for use in the registration statement, such prospectus or such form of prospectus or in any amendment or supplement thereto or (ii) in the case of an occurrence of an event of the type specified in Section 3(e)(vi)(y)-(z), the use by such Investor of an outdated or defective prospectus after the Company has notified such Investor in writing that the prospectus is outdated or defective and prior to the receipt by such Investor of Effective Notice pursuant to Section 3(c). In no event shall the liability of any selling Investor hereunder be greater in amount than the dollar amount of the net proceeds received by such Investor upon the sale of the Offering Shares giving rise to such indemnification obligation.

     (c) Conduct of Indemnification Proceedings. If any action, suit, investigation, or proceeding (including, without limitation, an investigation or partial proceeding, such as a deposition), whether commenced in writing (“Proceeding”) shall be brought or asserted against any Person entitled to indemnity hereunder (an “Indemnified Party”), such Indemnified Party shall promptly notify the Person from whom indemnity is sought (the “Indemnifying Party”) in writing, and the Indemnifying Party shall assume the defense thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all fees and expenses incurred in connection with defense thereof; provided, that the failure of any Indemnified Party to give such notice shall not relieve the Indemnifying Party of its obligations or liabilities pursuant to this Agreement, except (and only) to the extent that it shall be finally determined by a court of competent jurisdiction (which determination is not subject to appeal or further review) that such failure shall have proximately and materially adversely prejudiced the Indemnifying Party.

     An Indemnified Party shall have the right to employ separate counsel in any such Proceeding and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party or Parties unless: (i) the Indemnifying Party has agreed in writing to pay such fees and expenses; or (ii) the Indemnifying Party shall have failed promptly to assume the defense of such Proceeding and to employ counsel reasonably satisfactory to such Indemnified Party in any such Proceeding; or (iii) the named parties to any such Proceeding (including any impleaded parties) include both such Indemnified Party and the Indemnifying Party, and such Indemnified Party shall have been advised by counsel that a conflict of interest is likely to exist if the same counsel were to represent such Indemnified Party and the Indemnifying Party (in which case, if such Indemnified Party notifies the Indemnifying Party in writing that it elects to employ separate counsel at the expense of the Indemnifying Party, the Indemnifying Party shall not have the right to assume the defense thereof and such counsel shall be at the expense of the Indemnifying Party). It being understood, however, that the Indemnifying Party shall not, in connection with any one such Proceeding be liable for the fees and expenses of more than one separate firm of attorneys at any time for all Indemnified Parties, which firm shall be appointed by a majority of the Indemnified Parties; provided, however, that in the case a single firm of attorneys would be inappropriate due to actual or potential differing interests of conflicts between such Indemnified Parties and any other party represented by such counsel in such Proceeding or otherwise, then the Indemnifying Party shall be liable for the fees and expenses of one additional firm of attorneys with respect to such Indemnified Parties. The Indemnifying Party shall not be liable for any settlement of any such Proceeding effected without its written consent, which consent shall not be unreasonably withheld. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any pending Proceeding in respect of which any Indemnified Party is a party, unless such settlement includes an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such Proceeding.

     All fees and expenses of the Indemnified Party (including reasonable fees and expenses to the extent incurred in connection with investigating or preparing to defend such Proceeding in a manner not inconsistent with this Section 9) shall be paid to the Indemnified Party, as incurred, within ten (10) Trading Days of written notice thereof to the Indemnifying Party; provided, that the Indemnified Party shall reimburse all such fees and expenses to the extent it is finally judicially determined that such Indemnified Party is not entitled to indemnification hereunder.

     (d) Contribution. If any indemnification to which an Indemnified Party is entitled under the terms of Section 9(a) or (b) is unavailable to such Indemnified Party (by reason of public policy or otherwise) or indemnification is otherwise available to an Indemnified Party pursuant to Section 9(c), then each Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Losses, in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified Party in connection with the actions, statements or omissions that resulted in such Losses as well as any other relevant equitable considerations. The relative fault of such Indemnifying Party and Indemnified Party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission of a material fact, has been taken or made by, or relates to information supplied by, such Indemnifying Party or Indemnified Party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action, statement or omission. The amount paid or payable by a party as a result of any Losses shall be deemed to include, subject to the limitations set forth in Section 9(c), any reasonable attorneys’ or other reasonable fees or expenses incurred by such party in connection with any Proceeding to the extent such party would have been indemnified for such fees or expenses if the indemnification provided for in this Section 9 was available to such party in accordance with its terms. As used herein, the term “Losses” means any and all losses, claims, damages, liabilities, settlement costs and expenses, including, without limitation, costs of preparation and reasonable attorneys’ fees.

     The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 9(d) were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this Section 9, no Investor shall be required to contribute, in the aggregate, any amount in excess of the amount by which the net proceeds actually received by such Investor from the sale of the Offering Shares subject to the Proceeding exceeds the amount of any damages that such Investor has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. 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 who was not guilty of such fraudulent misrepresentation.

     The indemnity and contribution agreements contained in this Section 9 are in addition to any liability that the Indemnifying Parties may have to the Indemnified Parties, except that, in the event that the Closing occurs, the right to indemnification pursuant to this Section 9 shall be the sole remedy for breaches of representations and warranties contained in this Agreement or any certificate contemplated hereby.

     10. Survival. The representations and warranties contained in this Agreement or any certificate, including officer’s certificate, contemplated hereby or thereby, shall survive the Closing until the third anniversary of the Closing Date and shall thereupon expire, except to the extent that a notice of breach or inaccuracy of a representation or warranty is delivered to the party that breached such representation or warranty or made prior to such third anniversary. The

agreements and covenants contained in this Agreement or any Transaction Document or any certificate, instrument or document contemplated hereby or thereby shall survive the Closing.

     11. Notices. All notices and other communications provided for herein shall be in writing and shall be deemed to have been duly given if delivered personally or sent by registered or certified mail, return receipt requested, postage prepaid:

     13. Amendment. Prior to the Closing, this Agreement may not be modified, amended, waived or terminated except by an instrument in writing signed by the party against whom enforcement of such modification, waiver or termination is sought (except that two-thirds of the Investors based on their Commitment Amounts may act on behalf of all Investors, but only to the extent such modification, amendment, waiver or termination does not adversely affect any Investor in a manner different from other Investors). After the Closing, this Agreement may not be modified, amended, waived or terminated except by an instrument in writing signed by the party against whom enforcement of such modification, waiver or termination is sought (except that holders of two-thirds of the Offering Shares may act on behalf of all Investors and other Offering Holders, but only to the extent such modification, amendment, waiver or termination does not adversely affect any Investor or Offering Holder in a manner different from other Investors).

     14. Binding Effect. Except as otherwise provided herein, this Agreement shall be binding upon and inure to the benefit of the parties and their heirs, executors, administrators, successors,

legal representatives and assigns, and the agreements, representations, warranties and acknowledgments contained herein shall be deemed to be made by and be binding upon such heirs, executors, administrators, successors, legal representatives and assigns.

     15. Entire Agreement. The Transaction Documents, together with the Exhibits, Annexes and Schedules thereto, constitute the entire agreement of the Investors and the Company relating to the matters contained herein, superseding all prior written and prior or contemporaneous oral negotiations, understandings, arrangements, contracts or agreements.

     16. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York without giving effect to the principles of conflicts of law or any other principle that could require the application of the laws of any other jurisdiction. Each of the parties hereto hereby irrevocably and unconditionally consents to submit to the exclusive jurisdiction of the courts of the State of New York and of the United States of America, in each case located in the County of New York, for any Litigation arising out of or relating to this Agreement and the transactions contemplated hereby (and agrees not to commence any civil, criminal or administrative action, suit, claim, notice, hearing, examination, inquiry, proceeding or investigation at law or in equity or by or before any court, arbitrator or similar panel, governmental instrumentality or other agency (“Litigation”) relating thereto except in such courts), and further agrees that service of any process, summons, notice or document by U.S. registered mail to its respective address set forth in this Agreement, or such other address as may be given by one or more parties to the other parties in accordance with the notice provisions of Section 11, shall be effective service of process for any Litigation brought against it in any such court. Each of the parties hereto hereby irrevocably and unconditionally waives any objection to the laying of venue of any Litigation arising out of this Agreement or the transactions contemplated hereby in the courts of the State of New York or the United States of America, in each case located in the County of New York, and hereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such Litigation brought in any such court has been brought in an inconvenient forum.

     17. Severability. If any provision of this Agreement or the application thereof to Investor or any circumstance shall be held invalid or unenforceable to any extent, the remainder of this Agreement and the application of such provision to other subscriptions or circumstances shall not be affected thereby and shall be enforced to the greatest extent permitted by law.

     18. Independent Nature of Investors’ Obligations and Rights. The obligations of each Investor hereunder are several and not joint with the obligations of any other Investor, and no Investor shall be responsible in any way for the performance of the obligations of any other Investor hereunder. The decision of each Investor to purchase Shares pursuant to this Agreement has been made by such Investor independently of any other Investor and independently of any information, materials, statements or opinions as to the business, financial condition, results of operations, assets properties, liabilities, or prospects of the Company which may have been made or given by any other Investor or by any agent or employee of any other Investor, and no Investor or any of its agents or employees shall have any liability to any Investor (or any other person) relating to or arising from any such information, materials, statements or opinions. Nothing contained herein, and no action taken by any Investor pursuant thereto, shall be deemed to constitute the Investors as a partnership, an association, a joint venture or any other kind of

entity, or create a presumption that the Investors are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated hereby. Each Investor acknowledges that no other Investor has acted as agent for such Investor in connection with making its investment hereunder and that no other Investor will be acting as agent of such Investor in connection with monitoring its investment hereunder. Each Investor shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of this Agreement, and it shall not be necessary for any other Investor to be joined as an additional party in any proceeding for such purpose.

     19. Termination. This Agreement may be terminated (i) at any time prior to the Closing Date by mutual agreement of the Company and two-thirds of Investors (based on their Commitment Amounts), (ii) upon the termination of the Purchase Agreements, or (iii) by two-thirds of the Investors if the Closing Date has not occurred on or before November 3, 2006. Notwithstanding termination of this Agreement, Sections 6(n) (Expenses), 6(o) (Financing Fee), 9 (Indemnification) and 16 (Governing Law), shall remain in full force and effect.

     20. Headings. The headings in this Agreement are inserted for convenience and identification only and are not intended to describe, interpret, define, or limit the scope, extent or intent of this Agreement or any provision hereof.

     21. Counterparts. This Agreement may be executed in any number of counterparts, each of which when so executed and delivered shall be deemed to be an original and all of which together shall be deemed to be one and the same agreement.

     22. Specific Performance. The parties acknowledge that money damages are not an adequate remedy for violations of this Agreement and that any party may, in its sole discretion, apply to a court of competent jurisdiction for specific performance or injunctive or such other relief as such court may deem just and proper in order to enforce this Agreement or prevent any violation hereof and, to the extent permitted by applicable law, each party waives any objection to the imposition of such relief, this being in addition to any other remedy to which such party is entitled at law or in equity.

     23. Interpretation. The headings contained in this Agreement, in any Annex, Exhibit or Schedule hereto are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Any matter set forth on any Schedule shall be deemed set forth on all other Schedules if, in each case, it is reasonably apparent from the information disclosed that another schedule is also applicable. Except when the context requires otherwise, any reference in this Agreement to any Section, clause, Annex, Schedule or Exhibit shall be to the Sections and clauses of, and Schedules, Annexes and Exhibits to, this Agreement. The words “include,” “includes” and “including” are deemed to be followed by the phrase “without limitation.” Any reference to the masculine, feminine or neuter gender shall include such other genders and any reference to the singular or plural shall include the other, in each case unless the context otherwise requires. All Annexes, Exhibits and Schedules attached hereto or referred to herein are hereby incorporated in and made a part of this Agreement as if set forth in full herein. When a reference is made in this Agreement to a Section, Annex, Exhibit or Schedule, such reference shall be to a Section of, or an Annex, Exhibit or Schedule to, this Agreement unless otherwise indicated.

     IN WITNESS WHEREOF, each Investor has executed this Subscription and Registration Rights Agreement as of October 19, 2006.
