Article II Registration Rights; Restrictions on Transfer.

          2.1 Demand Registration.

               (a) At any time after the closing of an Initial Public Offering (but not within six (6) months of the effective date of a Registration Statement of the Company) or the seventh (7^th) anniversary of the Closing, whichever occurs first, the Requisite Investors may require that the Company register for sale under the Securities Act all or any portion of the Registrable Securities held by such Investors (the “Initiating Holders”) for sale in the manner specified in such notice; provided, that (i) the portion of the Registrable Securities required to be so registered equals at least 100% of the shares of Common Stock issuable upon conversion of the shares of Series H Preferred Stock then outstanding or (ii) such offering is expected to exceed $10,000,000 in the aggregate, counting all other securities of the Company being included in such offering (a “Demand Registration”).

               (b) Following receipt of any notice under Section 2.1, the Company shall (i) within ten (10) days of the receipt thereof, give written notice to all Holders (the “Registration Notice”) and (ii) use its best efforts to effect the registration under the Securities Act as soon as practicable, and in any event within one hundred eighty (180) days after receipt of such notice, for public sale in accordance with the method of disposition specified in such notice of the number of Registrable Securities which the Holders request to be registered, subject to the limitations of Section 2.1(d), within twenty (20) days following delivery of the Registration Notice by the Company in accordance with Section 3.6.

               (c) If the Initiating Holders intend to distribute the Registrable Securities covered by their notice by means of an underwriting, the Initiating Holders shall so advise the Company as a part of their demand made pursuant to this Section 2.1. If the method of disposition is an underwritten public offering, the Initiating Holders may designate the managing underwriter of such offering, which designation shall be subject to the Company’s approval, not to be unreasonably withheld. Each Holder may elect to include in such underwriting all or any part of the Registrable Securities it holds, subject to the limitations provided for in Section 2.1(d).

               (d) A Registration Statement filed pursuant to this Section 2.1 may, subject to the following provisions and in addition to the Registrable Securities held by Holders, include shares of Common Stock for sale by the Company for its own account for sale in accordance with the method of disposition specified by the Initiating Holders. If such registration shall be underwritten, the Company and all Holders proposing to distribute their shares through such underwriting shall enter into an underwriting agreement in customary form with the representative of the underwriter or underwriters selected for such underwriting. If and to the extent that the managing underwriter determines that marketing factors require a limitation on the number of shares to be included in such registration, then the shares of Common Stock sought to be registered by Holders who are not Investors (collectively, the “Other Stockholders”) and shares of Common Stock to be sold by the Company for its own account shall be excluded from such registration to the extent so required by such managing underwriter, and unless the Other Stockholders and the Company have otherwise agreed in writing, such exclusion shall be applied first to the shares of Common Stock of the Company to be included for its own account to the extent required by the managing underwriter and then to the shares sought to be registered by the Other Stockholders to the extent required by the managing underwriter. If, after exclusion of all shares sought to be registered by the Company and the Other Stockholders, the managing underwriter further determines that marketing factors require a limitation on the number of

Registrable Securities to be registered under this Section 2.1, then Registrable Securities held by Investors shall be excluded in accordance with Section 2.5 to the extent so required by the managing underwriter. In any event, all securities to be sold other than Registrable Securities shall be excluded prior to any exclusion of Registrable Securities. No Registrable Securities or other securities, in either case, excluded from the underwriting by reason of the underwriter’s marketing limitation shall be included in such registration. If any of the Holders who have requested inclusion in such registration as provided above, disapproves of the terms of the underwriting, then such Holders may elect to withdraw therefrom by written notice to the Company and the managing underwriter. The securities so withdrawn shall also be withdrawn from registration. The Company shall not include, and shall not permit other holders of its securities to include, any securities in such Demand Registration other than securities of the same class or series as the Registrable Securities to which the demand has been made pursuant to Section 2.1.

               (e) Notwithstanding the foregoing, if the Company shall furnish to the Holders requesting a Registration Statement pursuant to this Section 2.1, a certificate signed by the Chief Executive Officer of the Company stating that in the good faith judgment of the Board, it would be seriously detrimental to the Company and its stockholders for such Registration Statement to be filed and it is therefore essential to defer the filing of such Registration Statement, the Company shall have the right to defer taking action with respect to such filing for a period of not more than ninety (90) days after receipt of the request of the Initiating Holders; provided, however, that the Company may not utilize this right more than once in any twelve-month period.

               (f) In addition, the Company shall not be obligated to effect, or to take any action to effect, any registration pursuant to this Section 2.1:

               (i) After the Company has effected two registrations pursuant to this Section 2.1 which cover all the Registrable Securities sought to be included in such registrations and such registrations have been declared or ordered effective; or

               (ii) 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 registration subject to Section 2.2 hereof; provided that the Company is actively employing in good faith all reasonable efforts to cause such registration statement to become effective; or

               (iii) If the Initiating Holders propose to dispose of shares of Registrable Securities that may be immediately registered on Form S-3 pursuant to a request made pursuant to Section 2.3 below.

          2.2 Piggy-Back Registration.

               (a) If the Company at any time (other than pursuant to Section 2.1 or Section 2.3) proposes to register any of its securities under the Securities Act for sale to the public, whether for its own account or for the account of other stockholders of the Company or both (except with respect to (i) an Initial Public Offering, (ii) Registration Statements on Forms

S-4, S-8 or any successor to such forms, or (iii) any Registration Statement including only securities issued pursuant to a dividend reinvestment plan), each such time the Company shall promptly give written notice to the holders of Registrable Securities of its intention to do so (the “Piggy-Back Notice”). Upon the written request of a majority of the Holders (which majority must include the Lead Investor, so long as the Lead Investor holds at least 50% of the Series H Preferred Shares acquired by it pursuant to the Purchase Agreement), received by the Company within twenty (20) days after the delivery of such Piggy-Back Notice by the Company in accordance with Section 3.6, to register any or all of the Registrable Securities, the Company shall use its best efforts to cause the Registrable Securities as to which registration shall have been so requested to be included in such Registration Statement. If the Registration Statement relates to an underwritten public offering, the Company shall so advise the holders of Registrable Securities as a part of a Piggy-Back Notice. In such event, each Holder’s right to include Registrable Securities in such registration shall be conditioned upon its participation in such underwriting to the extent provided herein. The Holders, if participating in such distribution, shall enter into an underwriting agreement in customary form with the underwriter or underwriters selected for underwriting by the Company.

               (b) Any request by a Holder for inclusion in any registration may be withdrawn, in whole or in part, at any time prior to the effective date of the Registration Statement for such offering.

               (c) The Company shall have the right to terminate or withdraw any registration contemplated under this Section 2.2 prior to the effectiveness of such registration, whether or not the Holders have elected to include securities in such registration. The expenses of such registration shall be borne by the Company, in accordance with Section 2.6 hereof.

               (d) There shall be no limitation on the number of registrations a Holder may participate in under this Section 2.2.

          2.3 Registration on Form S-3. If at any time (i) Holders of at least thirty percent (30%) of the Registrable Securities then outstanding request that the Company file a Registration Statement on Form S-3 or any comparable or successor form thereto for a public offering of all or any portion of the Registrable Securities and (ii) the Company is a registrant entitled to use Form S-3 or any successor form thereto to effect the distribution of such Registrable Securities for public sale or resale (as the case may be), then the Company shall promptly give written notice of the proposed registration to all other Holders and shall use its best efforts to register under the Securities Act on Form S-3 or any comparable or successor form thereto, for public sale or resale (as the case may be) in accordance with the method of disposition specified in such notice, the number of Registrable Securities specified in such notice, together with the number of Registrable Securities requested by any other Holder or Holders for inclusion in such registration, received by the Company within fifteen (15) days after delivery of such notice by the Company. Whenever the Company is required by this Section 2.3 to use its best efforts to effect the registration of Registrable Securities, each of the procedures and requirements of Section 2.1 shall apply to such registration. Notwithstanding the foregoing, the Company shall not be obligated to effect any such registration pursuant to this Section 2.3: (1) if Form S-3 is not available for such offering by the Holders; (2) if the Holders, together with the holders of any other securities of the Company entitled to inclusion in such registration, propose to sell

Registrable Securities and such other securities (if any) at an aggregate price to the public (net of any underwriters’ discounts or commissions) of less than $2,500,000; or (3) if the Company shall furnish to the Holders a certificate signed by the President of the Company stating that in the good faith judgment of the Board, it would be materially detrimental to the Company and its stockholders for such Form S-3 registration to be effected at such time, in which event the Company shall have the right to defer the filing of the Form S-3 registration statement for a period of not more than sixty (60) days after receipt of the request of the Holder or Holders under this Section 2.3; provided, however, that the Company shall not utilize this right more than once in any twelve month period; (4) if the Company has already effected two registrations on Form S-3 for the Holders pursuant to this Section 2.3 within the immediately preceding 12 month period; or (5) in any particular jurisdiction in which the Company would be required to qualify to do business or to execute a general consent to service of process in effecting such registration, qualification or compliance. Subject to the foregoing, there shall be no limitation on the number of registrations on Form S-3 which may be requested and obtained under this Section 2.3.

          2.4 Registration Procedures. If and whenever the Company is required by the provisions of Sections 2.1, 2.2 or 2.3 to use its best efforts to effect the registration of any Registrable Securities under the Securities Act, the Company shall, as expeditiously as possible:

               (a) Prepare and file with the Commission a Registration Statement on the applicable form with respect to such securities and use its best efforts to cause such Registration Statement to become and remain effective until the earlier of (i) the sale of all of the Registrable Securities covered thereby and (ii) two years following the commencement of the offering thereunder; provided, however, that in the case of any registration of Registrable Securities on Form S-3 or on a comparable or successor form which are intended to be offered on a continuous or delayed basis, such two year period shall be extended, if necessary, until all such Registrable Securities are sold, provided that Rule 415 or any successor rule under the Securities Act permits an offering on a continuous or delayed basis; and provided, further, that, as soon as practicable but in no event later than five (5) Business Days before filing such Registration Statement, any related prospectus or any amendment or supplement thereto (other than any amendment or supplement made solely as a result of incorporation by reference of documents filed with the Commission subsequent to the filing of such Registration Statement), the Company shall furnish to (x) the Lead Investor for so long as the Lead Investor continues to hold 5% or more of the outstanding Registrable Securities or is an Affiliate of a director of the Company and (y) the underwriters, if any, copies of all such documents proposed to be filed, which documents shall be subject to review by the Lead Investor and any such underwriters;

               (b) Prepare and file with the Commission such amendments and supplements to such Registration Statement and the prospectus used in connection therewith as may be necessary to keep such Registration Statement effective for the period specified herein and comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities covered by such Registration Statement in accordance with the sellers’ intended method of disposition set forth in such Registration Statement for such period; provided, that the Company shall comply with the provisions of Section 2.4(a) above;

               (c) Furnish to the Holders and to each underwriter copies of the Registration Statement and each such amendment and supplement thereto (together with all

exhibits thereto) and the prospectus included therein and any other prospectus filed under Rule 424 or Rule 434 under the Securities Act as the Holders and such underwriter reasonably may request in order to facilitate the disposition of the Registrable Securities covered by such Registration Statement;

               (d) Use its best efforts to register or qualify the Registrable Securities covered by such Registration Statement under the securities or “blue sky” laws of such jurisdictions as the sellers of the Registrable Securities or, in the case of an underwritten public offering, the managing underwriter reasonably shall request; provided, however, that the Company shall not be required to (i) qualify to transact business as a foreign corporation in any jurisdiction where it is not so qualified, (ii) consent to general service of process or (iii) submit to taxation in any such jurisdiction, unless the Company is already subject to service or subject to taxation in such jurisdiction;

               (h) If the offering is underwritten, and at each Holder’s request, use its best efforts to furnish on the date that Registrable Securities are delivered to the underwriters for sale pursuant to such registration (i) an opinion, dated such date, of counsel to the Company, addressed to the underwriters and the Holders to such effect as reasonably may be requested by the underwriters, and (ii) a letter, dated such date, from the independent public accountants retained by the Company, addressed to the underwriters and, if applicable, the Holders requesting registration of Registrable Securities, in form and substance as is customarily given by independent public accountants to underwriters in an underwritten public offering, and deliver copies of such letter to such Holders;

               (i) Upon reasonable notice and at reasonable times during normal business hours, make available for inspection by (x) the Lead Investor for so long as the Lead Investor continues to hold 5% or more of the outstanding Registrable Securities or is an Affiliate of a director of the Company and (y) any underwriter participating in any distribution pursuant to such Registration Statement, and any attorney, accountant or other agent retained by such Holders or such underwriter, reasonable access to all financial and other records, pertinent corporate documents and properties of the Company, as such parties may reasonably request, and

               (m) Otherwise use its reasonable best efforts to comply with all applicable rules and regulations of the Commission under the Securities Act and the Exchange Act and take such other actions as may be reasonably necessary to facilitate the registration of the Registrable Securities hereunder; and make available to its security holders, as soon as reasonably practicable, but not later than the Availability Date (as defined below), an earnings statement covering a period of at least twelve (12) months, beginning after the effective date of each Registration Statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act (for the purpose of this Section 2.4(m), “Availability Date” means the forty-fifth (45^th) day following the end of the fourth fiscal quarter that includes the effective date of such Registration Statement, except that, if such fourth fiscal quarter is the last quarter of the Company’s fiscal year, “Availability Date” means the ninetieth (90^th) day after the end of such fourth fiscal quarter).

          2.5 Underwriting Requirements. In connection with any offering involving an underwriting of shares of the Company’s capital stock, the Company shall not be required to include any of the Registrable Securities in such underwriting unless the Holders accept the terms of the underwriting as agreed upon between the Company and its underwriters, and then only in such quantity as the underwriters in their sole discretion determine will not jeopardize the success of the offering by the Company. If the total number of securities, including Registrable Securities, requested by stockholders to be included in such offering exceeds the number of securities to be sold (other than by the Company) that the underwriters in their reasonable discretion determine is compatible with the success of the offering, then the Company shall be required to include in the offering only that number of such securities, including Registrable

Securities, which the underwriters and the Company in their sole discretion determine will not jeopardize the success of the offering. If the underwriters determine that less than all of the Registrable Securities requested to be registered can be included in such offering, then the Registrable Securities that are included in such offering shall be allocated among the selling Holders in proportion (as nearly as practicable) to the number of Registrable Securities owned by each selling Holder or in such other proportions as shall mutually be agreed to by all such selling Holders. Notwithstanding the foregoing, in no event shall (i) the number of Registrable Securities held by Investors included in the offering be reduced unless all other securities (including Registrable Securities held by Other Stockholders) are first entirely excluded from the offering, and (ii), subject to the immediately preceding clause (i), the number of Registrable Securities held by Other Stockholders included in the offering be reduced unless all other securities (excluding, for the avoidance of doubt, the Registrable Securities held by the Investors and any securities held by the Company) are first entirely reduced to zero.

          2.6 Expenses. The Company shall bear all reasonable expenses incurred in complying with Sections 2.1, 2.2, 2.3 and 2.4, including, without limitation, all registration and filing fees (exclusive of underwriting discounts and commissions attributable to the Registrable Securities being registered pursuant to the exercise of demand rights in accordance with Section 2.1 and fees of legal counsel other than one counsel for all selling Holders to be selected by the Lead Investor, printing expenses, fees and disbursements of counsel and independent public accountants for the Company, fees and expenses (including counsel fees) incurred in connection with complying with state securities or “blue sky” laws, reasonable fees and disbursements of transfer agents and registrars and costs of any insurance which might be obtained by the Company with respect to the offering by the Company.

          2.7 Indemnification and Contribution.

               (a) The Company shall indemnify and hold harmless, each Holder and its Affiliates and the directors, officers, employees, investors, partners and agents of each Holder and its Affiliates, from and against any and all losses, claims, damages, liabilities and expenses (including, without limitation, reasonable attorney fees and disbursements and other expenses incurred in connection with investigating, preparing or defending any action, claim or proceeding, pending or threatened and the costs of enforcement hereof) (collectively, “Losses”) to which any such Person may become subject, arising out of or based upon any untrue statement of a material fact contained in any Registration Statement covering any Registrable Securities, any related prospectus or preliminary prospectus, or any amendment or supplement thereto, or any omission to state in any thereof a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus or prospectus supplement, in light of the circumstances under which they were made) not misleading, except in each case insofar, but only insofar, as the same arises out of or is based upon an untrue statement or alleged untrue statement of a material fact or an omission or alleged omission to state a material fact in such Registration Statement, prospectus, preliminary prospectus, amendment or supplement, as the case may be, made or omitted, as the case may be, in express reliance upon and in strict conformity with written information furnished to the Company by the Holder expressly for use therein. This indemnity is in addition to any liability that the Company may otherwise have. The Company shall also indemnify any underwriters of the Registrable Securities, selling brokers, dealer managers and similar securities industry professionals participating in the distribution and their

officers and directors and each Person who controls such underwriters or other Persons (within the meaning of the Securities Act) to the same extent as provided above with respect to the indemnification of the Holder and its Affiliates as described above.

               (b) In connection with any Registration Statement covering Registrable Securities, each Holder shall furnish to the Company in writing such information with respect to the Holder as the Company reasonably requests for use in connection with such Registration Statement, any related Prospectus or preliminary prospectus, or any amendment or supplement thereto, and shall indemnify, to the fullest extent permitted by law, the Company, the Company’s directors, officers, employees and agents, each Person who controls the Company (within the meaning of the Securities Act), against all Losses arising out of or based upon any untrue statement of a material fact contained in any Registration Statement covering any Registrable Securities, any related Prospectus or preliminary prospectus, or any amendment or supplement thereto, or any omission to state in any such prospectus, amendment or supplement, a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus or prospectus supplement, in light of the circumstances under which they were made) not misleading, in each case to the extent, and only to the extent, that the same arises out of or is based upon an untrue statement of a material fact or an omission to state a material fact in such Registration Statement or in such related Prospectus, preliminary prospectus, amendment or supplement, as the case may be, made or omitted, as the case may be, in express reliance upon and in strict conformity with written information furnished to the Company by the Holder expressly for use therein. Notwithstanding any other provision of this Agreement, in no event shall the Holder’s indemnification obligation exceed the dollar amount of the proceeds received by the Holder upon the sale of the Registrable Securities giving rise to such obligation.

               (c) Promptly after receipt by any Person (the “Indemnified Person”) of notice of any demand, claim or circumstances which would or might give rise to a claim or the commencement of any action, proceeding or investigation in respect of which indemnity may be sought pursuant to Section 2.7, such Indemnified Person shall promptly notify the party obligated to provide indemnification under this Section 2.7 in respect thereof (an “Indemnifying Party”) and the Indemnifying Party shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such Indemnified Person, and shall assume the payment of all fees and expenses in connection with such defense and such counsel; provided, however, that the failure of any Indemnified Person to so notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations hereunder except to the extent that the Indemnifying Party is actually and materially prejudiced by such failure to notify. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless: (i) the Indemnifying Party and the Indemnified Person shall have mutually agreed to the retention of such counsel; or (ii) in the reasonable judgment of counsel to such Indemnified Person (x) representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them or (y) if there are one or more defenses available to such Indemnified Person that is/are not available to the Indemnifying Party. The Indemnifying Party shall not be liable for any settlement of any proceeding effected without its written consent, which consent shall not be unreasonably withheld, delayed or conditioned, but if settled with such consent, or if there be a final judgment for the plaintiff therein, the Indemnifying Party shall indemnify and hold harmless such Indemnified Person from and against any Losses by reason of such settlement or

judgment. Without the prior written consent of the Indemnified Person, which consent shall not be unreasonably withheld, delayed or conditioned, the Indemnifying Party shall not effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is a party, unless such settlement includes an unconditional release of such Indemnified Person from all liability arising out of such proceeding.

               (d) (i) If the indemnification provided for in this Section 2.7 from the Indemnifying Party is unavailable to an Indemnified Person hereunder or is inadequate in respect of any Losses for which indemnification is provided under this Section 2.7, then the Indemnifying Party, in lieu of indemnifying such Indemnified Person, shall contribute to the amount paid or payable by such Indemnified Person as a result of such Losses in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified Person(s) in connection with the actions that resulted in such Losses, as well as any other relevant equitable considerations. The relative fault of such Indemnifying Party and Indemnified Person 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 to state a material fact, has been made by, or relates to information supplied by, such Indemnifying Party or Indemnified Persons, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the Losses referred to above shall be deemed to include, subject to the limitations set forth in Section 2.7(c), any legal or other fees or expenses reasonably incurred by such party in connection with any investigation or proceeding.

                (ii) The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 2.7(d) were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding any other provision hereof, in no event shall the Holder’s contribution obligation exceed the excess of (A) the dollar amount of the proceeds received by the Holder upon the sale of the Registrable Securities giving rise to such contribution obligation over (B) the dollar amount of any damages that the Holder has otherwise been required to pay by reason of the untrue or alleged untrue statement or omission or alleged omission giving rise to such obligation. 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.

               (iii) If any provision of an indemnification or contribution clause in an underwriting agreement or agency agreement executed by or on behalf of the Holder differs from a provision in this Section 2.7, such provision in the underwriting agreement shall determine the Holder’s rights in respect thereof.

                (e) Notwithstanding anything in this Agreement to the contrary, the indemnities and obligations provided in this Section 2.7 shall survive the transfer of any Registrable Securities by the Holder.

          2.8 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission which may at any time permit the sale of the Registrable Securities to the public without registration, so long as the Company is subject to the reporting

requirements of the Exchange Act, the Company shall:

               (a) make and keep public information available, as contemplated in Rule 144 under the Securities Act (or any successor rule); and

               (b) use its best efforts to file with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act.

          2.9 Furnishing Information. It shall be a condition precedent to the obligations of the Company to take any action pursuant to this Article II that each Holder furnish to the Company in writing such information regarding such Holder, the Registrable Securities held by it and the intended method of disposition of such securities as shall be required to effect the registration thereof.

          2.10 Additional Registration Rights. The Company shall not, after the date hereof, enter into any agreement providing any registration rights to any of its security holders or potential security holders, without the prior written consent of holders of a majority of the Registrable Securities (which consent must include the Lead Investor so long as the Lead Investor holds at least 50% of the Series H Preferred Shares acquired by it pursuant to the Purchase Agreement, unless such registration rights are subordinate to the registration rights of the Holders hereunder).

          2.11 Restrictions on Transfer.

               (a) Each Holder agrees not to make any disposition of all or any portion of the Preferred Stock unless and until:

               (i) there is then in effect a registration statement under the Securities Act covering such proposed disposition and such disposition is made in accordance with the “Plan of Distribution” contained in such registration statement;

               (ii) (A) the transferee has agreed in writing to be bound by the terms of this Agreement, (B) such Holder shall have notified the Company of the proposed disposition and shall have furnished the Company with a detailed statement of the circumstances surrounding the proposed disposition, and (C) if reasonably requested by the Company, such Holder shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, that such disposition will not require registration of such shares under the Securities Act; or

               (iii) The shares of Preferred Stock are then eligible for transfer pursuant to Rule 144 promulgated under the Securities Act. Furthermore, it is agreed that the Company will not require opinions of counsel for transactions made pursuant to Rule 144 of the Securities Act.

               (b) Notwithstanding the provisions of subsection (a) above, no such restriction shall apply to a transfer by a Holder that is (A) a partnership transferring to its partners or former partners in accordance with partnership interests, (B) a corporation

transferring to a parent corporation that owns a majority of the capital stock of the Holder, to a majority-owned subsidiary, or to an affiliate under common control with the Holder, (C) a limited liability company transferring to its members or former members in accordance with their interest in the limited liability company, (D) a Holder transferring to its affiliated venture capital fund or affiliated trust, (E) an individual transferring to the Holder’s family member or trust for the benefit of an individual Holder, (F) a trust transferring to a trust beneficiary or affiliated trust, or (G) a Holder transferring to any transferee that is a Major Investor, provided that the Company is given written notice thereof; provided that in each case the transferee will agree in writing to be subject to the terms of this Agreement to the same extent as if he were an original Holder hereunder.

               (c) So long as the Registrable Securities are not (i) covered by an effective registration statement; and/or (ii) eligible for transfer pursuant to Rule 144 promulgated under the Securities Act, each certificate representing Registrable Securities shall be stamped or otherwise imprinted with legends substantially similar to the following (in addition to any legend required under applicable state securities laws):

Agreement or any other Transaction Document to which it is a party. The decision of each Investor to purchase Series H Preferred Shares and Warrants pursuant to the Purchase Agreement and the other Transaction Documents has been made by such Investor independently of any other Investor. Nothing contained herein or in any other Transaction Document, and no action taken by any Investor (including, without limitation, the Lead Investor) pursuant hereto or 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 by this Agreement or the other Transaction Documents. Each Investor acknowledges that no other Investor (including, without limitation, the Lead Investors) has acted as agent for such Investor in connection with making its investment under the Purchase Agreement and that no Investor (including, without limitation, the Lead Investors) will be acting as agent of such Investor in connection with monitoring its investment in the Series H Preferred Shares or enforcing its rights under this Agreement or the other Transaction Documents. Each Investor shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of this Agreement or out of the other Transaction Documents to which it is a party, and it shall not be necessary for any other Investor to be joined as an additional party in any proceeding for such purpose. The Company acknowledges that each of the Investors has been provided with the same Transaction Documents for the purpose of closing a transaction with multiple Investors and not because it was required or requested to do so by any Investor. Notwithstanding anything contained in this Agreement or any other Transaction Document to the contrary, the Lead Investors shall not have any duty, fiduciary or otherwise, to any other Investor by virtue of such investor serving as the Lead Investor or otherwise.
