ARTICLE II

REGISTRATION RIGHTS

     Section 2.1 Demand Registrations.

     (a) If at any time after the Blackout Period (as defined in the Governance Agreement), the Company shall receive a notice from Purchaser that the Company effect a Demand Registration (a “Demand Notice”), for all or any portion of the Registrable Securities specified in such Demand Notice, specifying the intended method of disposition thereof, then the Company shall use its reasonable best efforts to effect within 60 days of such Demand Notice, subject to the restrictions of this Section 2.1, the registration under the Securities Act of the Registrable Securities for which Purchaser has requested registration under this Section 2.1, all to the extent necessary to permit the disposition (in accordance with the intended methods thereof as specified in the Demand Notice) of the Registrable Securities so to be registered.

     (b) Subject to the provisions of this Section 2.1, Purchaser shall be entitled to request four (4) Demand Registrations.

     (c) Subject to Section 2.1(e), the Company shall file the registration statement in respect of a Demand Registration as soon as practicable and, in any event, within 45 days after receiving a Demand Notice (the “Required Filing Date”) on Form S-1 or S-3 or any similar or successor to such forms under the Securities Act, or, if they are not available, any form for which the Company then qualifies, and which form shall be available for the sale of the Registrable Securities in accordance with the intended methods of distribution thereof, and shall use its reasonable best efforts to cause the same to be declared effective by the SEC as promptly as practicable after such filing; provided, that the Company shall not be obligated to effect a Demand Registration pursuant to Section 2.1(a) (i) within 180 days after the effective date of a previous Demand Registration and (ii) unless the Demand Notice is for a number of Registrable Securities with an expected market value that is equal to at least $50,000,000 as of the date of such Demand Notice or is for one hundred percent of Registrable Securities.

     (d) With respect to any Demand Registration, subject to the availability of a registration statement on Form S-3, the Company shall, upon written request from Purchaser, agree to effect a Shelf Registration, and, thereafter, shall use its reasonable best efforts to cause such registration statement to be declared effective under the Securities Act as promptly as practicable after the filing thereof.

     (e) The Company may defer the filing (but not the preparation) of a registration statement required by this Section 2.1 until after the Required Filing Date (i) for a period not to exceed 90 days, if, at the time the Company receives the Demand Notice, there exists a Material Disclosure Event, or (ii) for a period not to exceed 90 days, if, prior to receiving the Demand Notice, the Company had determined to effect a registered underwritten public offering of Company Common Stock, or securities convertible into or exchangeable for Company Common Stock, for the Company’s account in connection with a material public financing transaction and the Company had taken substantial steps (including selecting a managing underwriter for such offering, if applicable) and is proceeding with reasonable diligence to effect such offering. A deferral of the filing of a registration statement pursuant to this Section 2.1(e) shall be lifted, and the requested registration statement shall be filed forthwith, if, in the case of a deferral pursuant to clause (i) of the preceding sentence, the Material Disclosure Event is publicly disclosed or otherwise ceases to exist, or, in the case of a deferral pursuant to clause (ii) of the preceding sentence, the proposed registration for the Company’s account is abandoned or the filing of a registration statement with respect to any such proposed registration is delayed by more than 30 days from the time of receipt of the applicable Demand Notice. In order to defer the filing of a registration statement pursuant to this Section 2.1(e), the Company shall promptly (but in any event within 10 days), upon determining to seek such deferral, deliver to Purchaser a certificate signed by an executive officer of the Company stating that the Company is deferring such filing pursuant to this Section 2.1(e), a general statement of the reason for such deferral and an approximation of the anticipated delay. Within 20 days after receiving such certificate, Purchaser may withdraw such Demand Notice by giving notice to the Company; if withdrawn, the Demand Notice shall be deemed not to have been made for all purposes of this Agreement and the Company shall pay all expenses of such withdrawn Demand Registration in accordance with Section 2.7. The Company may defer the filing of a particular registration statement pursuant to this Section 2.1(e) only once in any period of 12 consecutive months; provided, that any deferral pursuant to clause (i) of the first sentence of this Section 2.1(e) shall be deemed to be a “Suspension Period” for purposes of Section 2.6 and shall be subject to the limitations and obligations during Suspension Periods set forth in Section 2.6.

     (f) No securities to be sold for the account of any Person (including the Company), other than Purchaser shall be included in a Demand Registration if the managing underwriters (or, in an offering that is not underwritten, a nationally recognized investment bank) shall advise the Company and

Purchaser in writing that the aggregate amount of such securities requested to be included in any offering pursuant to such Demand Registration is sufficiently large to have an adverse effect on the success of any such offering, based on market conditions or otherwise (an “Adverse Effect”). Furthermore, if the managing underwriters (or such investment bank) shall advise the Company and Purchaser that, even after exclusion of all securities of other Persons pursuant to the immediately preceding sentence, the amount of Registrable Securities proposed to be included in such Demand Registration by Purchaser is sufficiently large to cause an Adverse Effect, the Registrable Securities of Purchaser to be included in such Demand Registration shall equal the number of shares which Purchaser is so advised can be sold in such offering without an Adverse Effect; provided, that the Company shall not include any Registrable Securities of any executive officer, director or employee of the Company or any of its subsidiaries if the managing underwriters (or such investment bank) shall advise the Company and Purchaser that the participation of any such persons may have an Adverse Effect; provided, further that if the number of Registrable Securities to be included in the Demand Registration is less than 80% of the number requested to be so included, Purchaser may withdraw such Demand Notice by giving notice to the Company; if withdrawn, the Demand Notice shall be deemed not to have been made for all purposes of this Agreement and the Company shall pay all expenses of such withdrawn Demand Registration in accordance with Section 2.7; provided, however, that if the holders of a majority of the remaining Registrable Securities covered by such Demand Notice desire to proceed with such Demand Registration, the Company shall proceed forward with such Demand Registration and the Demand Notice shall be deemed to have been made for all purposes of this Agreement by the remaining holders.

     (g) Purchaser may withdraw Registrable Securities from a Demand Registration at any time and Purchaser shall have the right to cancel a proposed Demand Registration of Registrable Securities pursuant to this Section 2.1(g). Upon such cancellation, the Company shall cease all efforts to secure registration and such Demand Registration shall not be counted as a Demand Registration under this Agreement for any purpose and the Company shall pay the expenses of such cancelled Demand Registration in accordance with Section 2.7.

     (h) In any registration requested pursuant to this Section 2.1, the Company shall not register securities other than Registrable Securities for sale for the account of any Person (including the Company), unless permitted to do so by the written consent of Purchaser.

     Section 2.2 Piggyback Registrations.

     (a) Whenever the Company proposes to register any of its equity securities under the Securities Act (other than a registration statement on Form S-8 or on Form S-4 or any similar successor forms), whether for its own account or for the account of one or more stockholders of the Company, the Company shall each such time give prompt written notice at least 20 business days prior to the anticipated filing date of the registration statement relating to such registration to Purchaser, which notice shall set forth Purchaser’s rights under this Section 2.2 and shall offer Purchaser the opportunity to include in such registration the number of Registrable Securities of the same class or series as those proposed to be registered as Purchaser may request, subject to the provisions of Sections 2.2(a), 2.2(b) and 2.2(c). Upon the request of Purchaser made within 15 business days after the receipt of notice from the Company (which request shall specify the number of Registrable Securities, if any, intended to be registered by Purchaser), the Company shall use its reasonable best efforts to effect the registration under the Securities Act of all Registrable Securities that the Company has been so requested to register by Purchaser to the extent necessary to permit the disposition of the Registrable Securities so to be registered; provided, that (i) if such registration involves an Underwritten Offering, Purchaser must sell all Registrable Securities to the underwriters selected by the Company on the same terms and conditions as apply to the Company, as applicable, and (ii) if, at any time after giving notice of its intention to register any securities pursuant to this Section 2.2(a) and prior to the effective date of the registration statement filed in connection with

such registration, the Company shall determine for any reason not to register such securities, the Company shall give notice to Purchaser and, thereupon, shall be relieved of its obligation to register any Registrable Securities in connection with such registration. No registration effected under this Section 2.2 shall relieve the Company of its obligations to effect a Demand Registration to the extent required by Section 2.1. There shall be no limitation on the number of Piggyback Registrations that the Company shall be required to effect under this Section 2.2.

     (b) At any time prior to the effective date of the registration statement relating to such registration, Purchaser may revoke such Piggyback Registration request by providing a notice to the Company revoking such request.

     (c) If a Piggyback Registration is in respect of an Underwritten Offering and was initiated by the Company, and if the managing underwriters advise the Company that the inclusion of Registrable Securities requested to be included in the registration statement pursuant to this Section 2.2 would cause an Adverse Effect, then the Company shall be required to include in such registration statement, to the extent of the amount of securities that the managing underwriters advise may be sold without causing such Adverse Effect, (A) first, the securities the Company proposes to sell; (B) second, the Registrable Securities requested to be included in such registration by Purchaser thereof; and (C) third, any other securities requested to be included in such registration; provided, that the Company shall not include any Registrable Securities of any executive officer or employee of the Company or any of its subsidiaries (other than the Stockholders) if such managing underwriters advise the Company and the requesting Stockholders that the participation of any such individual may have an Adverse Effect. If, as a result of the provisions of this Section 2.2(c), any Stockholder shall not be entitled to include all Registrable Securities in a registration that such Stockholder has requested to be so included, such Stockholder may withdraw such Stockholder’s request to include Registrable Securities in such registration statement.

     (d) If a Piggyback Registration is in respect of an Underwritten Offering and was initiated by a security holder of the Company (other than a Stockholder), and if the managing underwriters advise the Company that the inclusion of Registrable Securities requested to be included in the registration statement would cause an Adverse Effect, the Company shall include in such registration statement, to the extent of the amount of securities that the managing underwriters advise may be sold without causing such Adverse Effect, (A) first, the Registrable Securities requested to be included in such registration by any Stockholder thereof, pro rata among the Stockholders on the basis of the number of Registrable Securities requested to be registered by each such Stockholder; and (B) second, any other securities requested to be included in such registration (including securities to be sold for the account of the Company); provided, that the Company shall not include any Registrable Securities of any executive officer or employee of the Company or any of its subsidiaries (other than Purchaser) if such managing underwriters advise the Company and Purchaser that the participation of any such individual may have an Adverse Effect. If, as a result of the provisions of this Section 2.2(d), Purchaser shall not be entitled to include all Registrable Securities in a registration that Purchaser has requested to be so included, Purchaser may withdraw its request to include Registrable Securities in such registration statement.

     (e) Notwithstanding any of the foregoing, the provisions of Sections 2.2(c) and 2.2(d) shall not apply to a Piggyback Registration that is a Shelf Registration.

     Section 2.3 SEC Forms. The Company shall use its reasonable best efforts to cause any Demand Registrations to be registered on Form S-3 (or any successor form), if applicable, once the Company becomes eligible to use Form S-3. If the Company is not then eligible under the Securities Act to use Form S-3, such Demand Registrations shall be registered on the form for which the Company then qualifies. The Company shall use its best efforts to become and remain eligible to use Form S-3. All such registration statements shall comply with applicable requirements of the Securities Act, and, together

with each prospectus included, filed or otherwise furnished by the Company in connection therewith, shall not contain any untrue statement of material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading.

     Section 2.4 Holdback Agreements.

     (a) The Company agrees (i) not to effect any public sale or distribution of its equity securities, or any securities convertible into or exchangeable or exercisable for such securities, except pursuant to Excluded Registrations, during the seven days prior to the effective date of any registration statement in connection with a Demand Registration or Piggyback Registration and thereafter until the date on which all of the Registrable Securities subject to such registration statement have been sold (not to exceed 90 days, as required by the underwriters managing the offering) and (ii) if requested by the managing underwriters, to use reasonable efforts to cause each director and executive officer to agree not to effect any public sale or distribution (including sales pursuant to Rule 144 of the Securities Act) of any such securities during such period (except as part of such underwritten registration, if otherwise permitted); provided, that the foregoing described holdback shall not apply to the extent that the managing underwriters of such offering otherwise agree or, in the event a registration statement does not relate to an Underwritten Offering, if the holders of a majority of such Registrable Securities consent thereto.

     (b) If Purchaser notifies the Company in writing that it intends to effect an underwritten sale of Company Common Stock registered pursuant to a Shelf Registration, the Company agrees (i) not to effect any public sale or distribution of its equity securities, or any securities convertible into or exchangeable or exercisable for its equity securities, during the seven days prior to and during the 90-day period beginning on the filing of the prospectus supplement with respect to such offering, other than pursuant to Excluded Registrations or to the extent that the managing underwriters of such offering otherwise agree and (ii) if requested by the managing underwriters, to use reasonable efforts to cause each director and executive officer to agree not to effect any public sale or distribution (including sales pursuant to Section 144) of any such securities during such period (except as part of such underwritten registration, if otherwise permitted).

     (c) Purchaser agrees, in the event of an Underwritten Offering by the Company (whether for the account of the Company or otherwise), not to effect any public sale or distribution of any Registrable Securities, or any securities convertible into or exchangeable or exercisable for such Registrable Securities, including any sale pursuant to Rule 144 (except as part of such Underwritten Offering), during the seven days prior to and ending up to 90 days after the date of the final prospectus, subject in each case to such extensions as are customary to permit the publication of research in compliance with Rule 2711(f) of the rules of the National Association of Securities Dealers, Inc. as incorporated in the FINRA Rules (or any similar successor rule thereto); provided, that each other stockholder of the Company and each executive officer of the Company is subject to substantially the same restrictions.

     Section 2.5 Registration Procedures. Whenever Purchaser has requested that any Registrable Securities be registered pursuant to this Agreement, the Company shall use its best efforts to effect the registration and the sale of such Registrable Securities in accordance with the intended method of disposition thereof as promptly as is practicable, and pursuant thereto the Company shall as expeditiously as possible:

     (a) prepare and file with the SEC by the Required Filing Date a registration statement on the appropriate form under the Securities Act with respect to such Registrable Securities and use its best efforts to cause such registration statement to become effective as soon as practicable after the initial filing thereof; provided, that as far in advance as practicable before filing such registration statement or

any amendment or supplement thereto, the Company shall furnish to Purchaser copies of reasonably complete drafts of all such documents prepared to be filed (including exhibits and documents that are to be incorporated by reference into the registration statement, amendment or supplement), and Purchaser shall have the opportunity to object to any information contained therein and the Company shall make any corrections or other amendments reasonably requested by Purchaser with respect to such information prior to filing any such registration statement, amendment or supplement;

     (b) except in the case of a Shelf Registration, prepare and file with the SEC such amendments, post-effective 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 a period of not less than 180 days (or such lesser period as is necessary for the underwriters in an Underwritten Offering to sell unsold allotments) and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement during such period in accordance with the intended methods of disposition by the sellers thereof set forth in such registration statement;

     (c) in the case of a Shelf Registration, prepare and file with the SEC 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 and to comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities subject thereto for a period ending on the earlier of (i) 24 months after the effective date of such registration statement and (ii) the date on which all the Registrable Securities subject thereto have been sold pursuant to such registration statement;

     (d) furnish to Purchaser and the underwriters, if any, of the securities being registered such number of copies of such registration statement, each amendment and supplement thereto, the prospectus included in such registration statement (including each preliminary prospectus and any summary prospectus), any documents incorporated by reference therein and such other documents as Purchaser or underwriters reasonably may request in order to facilitate the disposition of the Registrable Securities owned by Purchaser or the sale of such securities by such underwriters (it being understood that, subject to this Section 2.5 and the requirements of the Securities Act and applicable state securities laws, the Company consents to the use of the prospectus and any amendment or supplement thereto by Purchaser and the underwriters in connection with the offering and sale of the Registrable Securities covered by the registration statement of which such prospectus, amendment or supplement is a part);

     (e) use its best efforts to register or qualify such Registrable Securities under such other securities or “blue sky” laws of such jurisdictions as Purchaser or the managing underwriters reasonably request; use its reasonable best efforts to keep each such registration or qualification (or exemption therefrom) effective during the period in which such registration statement is required to be kept effective; and do any and all other acts and things which may be reasonably necessary or advisable to enable Purchaser to consummate the disposition of the Registrable Securities owned by Purchaser in such jurisdictions; provided, that the Company shall not be required to (i) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this subparagraph or (ii) consent to general service of process in any such jurisdiction;

     (f) promptly notify Purchaser and each underwriter, if any, in writing (i) when a prospectus or any prospectus supplement or post-effective amendment has been filed and, with respect to a registration statement or any post-effective amendment, when the same has become effective; (ii) of the issuance by any state securities or other regulatory authority of any order suspending the qualification or exemption from qualification of any of the Registrable Securities under state securities or “blue sky” laws or the initiation or threat of initiation of any proceedings for that purpose; and (iii) if such registration statement or related prospectus, at the time it or any amendment thereto became effective or at any time

such prospectus is required to be delivered under the Securities Act, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, upon the discovery by the Company of such material misstatement or omission or of the happening of any event as a result of which the Company believes there would be such a material misstatement or omission; provided, that, in the case of clause (iii), promptly after delivery of such notice, the Company shall, as the case may be, (x) prepare and file with the SEC a post-effective amendment to such registration statement and use its best efforts to cause such amendment to become effective so that such registration statement, as so amended, shall not contain any untrue statement of a material fact or omit a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading or (y) prepare and furnish a supplement or amendment to such prospectus so that, as thereafter deliverable to the purchasers of such Registrable Securities, such prospectus shall not contain any untrue statement of a material fact or omit a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading;

     (g) permit Purchaser to participate in the preparation of such registration statement or related prospectus and promptly incorporate any information furnished to the Company by Purchaser that, in the reasonable judgment of Purchaser and its counsel, should be included if Purchaser, in its sole and exclusive judgment, might reasonably be deemed to be an underwriter or a controlling person of the Company (within the meaning of the Securities Act);

     (h) make reasonably available senior management of the Company, as selected by Purchaser, to assist in the marketing of the Registrable Securities covered by such registration, including the participation of such members of the Company’s senior management in “road show” presentations and other customary marketing activities, including “one-on-one” meetings with prospective purchasers of the Registrable Securities to be sold in the Underwritten Offering and otherwise to facilitate, cooperate with, and participate in each proposed offering contemplated herein and customary selling efforts related thereto, in each case to the same extent as if the Company were engaged in a primary registered offering of its capital stock; provided, that such assistance does not unduly interfere with the normal operations of the Company in the ordinary course of business, consistent with past practice;

     (i) otherwise use its best efforts to comply with all applicable rules and regulations of the SEC, including the Securities Act and the Exchange Act, and make generally available to the Company’s security holders an earnings statement satisfying the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder, as soon as reasonably practicable, but no later than 30 days after the end of the 12-month period beginning with the first day of the Company’s first fiscal quarter commencing after the effective date of a registration statement, which earnings statement shall cover said twelve (12)-month period; provided, that such requirement shall be deemed satisfied if the Company timely files complete and accurate information on Forms 10-Q, 10-K and 8-K under the Exchange Act as required thereby and otherwise complies with Rule 158 under the Securities Act;

     (j) in the case of an Underwritten Offering, if requested by the managing underwriters or Purchaser, promptly incorporate in a prospectus supplement or post-effective amendment such information as the managing underwriters or Purchaser reasonably requests to be included therein, including with respect to the Registrable Securities being sold by Purchaser, the purchase price being paid therefor by the underwriters and with respect to any other terms of the Underwritten Offering of the Registrable Securities to be sold in such offering, and promptly make all required filings of such prospectus supplement or post-effective amendment;

     (t) notify Purchaser promptly of any written comments by the SEC or any request by the SEC for the amending or supplementing of such registration statement or prospectus or for additional information;

Purchaser shall be party to any such underwriting agreement, and the representations and warranties by, and the other agreements on the part of, the Company to and for the benefit of such underwriters shall also be made to and for the benefit of Purchaser;

     (v) make every reasonable effort to prevent the entry of any order suspending the effectiveness of the registration statement and, in the event of the issuance of any such stop order, or of any order suspending or preventing the use of any related prospectus or suspending the qualification of any security included in such registration statement for sale in any jurisdiction, the Company shall use commercially reasonable efforts promptly to obtain the withdrawal of such order;

     (w) provide a CUSIP number for all Registrable Securities not later than the effective date of the registration statement with respect thereto;

     (x) in connection with an Underwritten Offering make such representations and warranties to Purchaser of such Registrable Securities and the underwriters with respect to the Registrable Securities and the registration statement as are customarily made by issuers to underwriters in primary Underwritten Offerings and deliver such documents and certificates as may be reasonably requested by each seller of Registrable Securities covered by the registration statement and by the underwriters to evidence compliance with such representations and warranties and with any customary conditions contained in the underwriting agreement or other agreement entered into by the Company; and

     (y) advise Purchaser, promptly after it shall receive notice or obtain knowledge thereof, of the issuance or threat of issuance of any stop order by the SEC suspending the effectiveness of such registration statement or the initiation or threatening of any proceeding for such purpose and promptly use its best efforts to prevent the issuance of any stop order or to obtain its withdrawal at the earliest possible moment if such stop order should be issued.

     Section 2.6 Suspension of Disposition. Purchaser agrees by acquisition of any Registrable Securities that, upon receipt of any notice (a “Suspension Notice”) from the Company of the happening of any Material Disclosure Event, Purchaser shall promptly discontinue disposition of Registrable Securities until receipt of the copies of the supplemented or amended prospectus, or until it is advised in

writing by the Company (the “Advice”) that the use of the prospectus may be resumed, and has received copies of any additional or supplemental filings that are incorporated by reference in the prospectus, and, if so directed by the Company, Purchaser shall deliver to the Company all copies, other than permanent file copies then in its possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice. In the event the Company shall give any Suspension Notice, the time period regarding the effectiveness of registration statements set forth in Sections 2.5(b) and 2.5(c) hereof shall be extended by the number of days during the period from and including the date of the giving of the Suspension Notice to and including the date when each seller of Registrable Securities covered by such registration statement shall have received the copies of the supplemented or amended prospectus or the Advice (such period, a “Suspension Period”). The Company shall use its best efforts and take such actions as are reasonably necessary to render the Advice as promptly as practicable and shall as promptly as practicable after the expiration of the Suspension Period prepare a post-effective amendment or supplement to the registration statement or the prospectus or any document incorporated therein by reference, or file any required document so that, as thereafter delivered to purchasers of the Registrable Securities included therein, the prospectus will not include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. Notwithstanding anything herein to the contrary, the Company shall not be entitled to more than two Suspension Periods during any consecutive 12-month period, which Suspension Periods shall have durations of not more than 90 days each; provided, that a Suspension Period shall automatically expire upon the public disclosure of the information to which the Material Disclosure Event relates. The fact that a Suspension Period is in effect under this Section 2.6 shall not relieve the contractual obligations of the Company as set forth in Section 2.5 or in any SEC rules to file timely reports and otherwise file material required to be filed under the Exchange Act.

     Section 2.7 Registration Expenses. The Company shall pay all out-of-pocket fees and expenses incident to any Demand Registration or Piggyback Registration, including all expenses incident to the Company’s performance of or compliance with this Article 2, all registration and filing fees, all internal fees and expenses of the Company (including any allocation of salaries of employees of the Company or any of its subsidiaries or other general overhead expenses of the Company and its subsidiaries or other expenses related to the preparation of financial statements or other data normally prepared by the Company and its subsidiaries in the ordinary course of business and expenses of its officers and employees performing legal or accounting duties), all fees and expenses associated with filings required to be made with the FINRA (including, if applicable, the reasonable fees and expenses of any “qualified independent underwriter” as such term is defined in Schedule E of the By-Laws of the FINRA, and of its counsel) or with any other applicable governmental authority, as may be required by the rules and regulations of the FINRA or such other governmental authority, fees and expenses of compliance with securities or “blue sky” laws (including reasonable fees and disbursements of counsel in connection with “blue sky” qualifications of the Registrable Securities), rating agency fees, printing expenses (including expenses of printing certificates for the Registrable Securities in a form eligible for deposit with Depository Trust Company and of printing prospectuses if the printing of prospectuses is requested by a holder of Registrable Securities), messenger, duplicating, distribution and delivery expenses, the expense of any annual audit or quarterly review, the expense of any liability insurance, the fees and expenses incurred in connection with any listing or quotation of the Registrable Securities, fees and expenses of counsel for the Company and its independent certified public accountants (including the expenses of any special audit or “cold comfort” letters required by or incident to such performance), the fees and expenses of any special experts retained by the Company in connection with such registration and the reasonable fees and expenses of any one counsel for Purchaser shall be paid for by the Company, which counsel shall be selected by Purchaser. Any underwriting discounts, commissions, or fees attributable to the sale of the Registrable Securities shall be borne by Purchaser whether or not any registration statement becomes effective, and the fees and expenses of any counsel, accountants, or other persons retained or employed by Purchaser (other than as set forth in the preceding sentence) shall be borne by Purchaser.

     Section 2.8 Underwritten Offering.

     (a) At the request of Purchaser, the offering of Registrable Securities pursuant to such Demand Registration including pursuant to a Shelf Registration, shall be in the form of an Underwritten Offering. Purchaser shall select (i) the investment banking firm or firms to manage the Underwritten Offering and (ii) counsel to Purchaser; provided, that, in the case of clause (i), such selection shall be subject to the consent of the Company, which consent shall not be unreasonably withheld or delayed. Purchaser may not participate in any Underwritten Offering pursuant to this Agreement unless Purchaser (x) agrees to sell Registrable Securities on the basis provided in any underwriting agreement described above as agreed upon by the Company and accepts the underwriters selected in accordance with the procedures described in this Section 2.8. and (y) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting agreements; provided, that Purchaser shall not be required to make any representations or warranties in connection with any such registration other than representations and warranties as to (i) Purchaser’s ownership of the Registrable Securities to be transferred free and clear of all liens, claims, and encumbrances created by Purchaser, (ii) Purchaser’s power and authority to effect such transfer, and (iii) such matters pertaining to Purchaser’s compliance with securities laws as may be reasonably requested; provided, further that any obligation of Purchaser to indemnify any Person pursuant to any such underwriting agreement shall be limited to the net amount received by Purchaser from the sale of Registrable Securities pursuant to such registration (which amounts shall include the amount of cash or the fair market value of any assets in exchange for the sale or exchange of such Registrable Securities or that are the subject of a distribution); provided, further that this Section 2.8(a) shall not require Purchaser to agree to any lock up agreement, market standoff agreement or holdback agreement other than those permitted by Section 2.4.

     (b) If Registrable Securities are to be sold in a Underwritten Offering, the Company agrees to include in the registration statement, or in the case of a Shelf Registration, a prospectus supplement, to be used all such information as may be reasonably requested by the underwriters for the marketing and sale of such Registrable Securities.

     Section 2.9 Indemnification.

     (a) In connection with each Demand Registration or Piggyback Registration, the Company shall indemnify and hold harmless Purchaser, the officers, directors and agents and employees of Purchaser, each Person who controls Purchaser (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the directors, officers, agents and employees of each such controlling Person, from and against any and all losses, claims, damages, liabilities, judgment, costs (including, without limitation, reasonable attorneys’ fees) (collectively, “Losses”), arising out of or based upon any untrue or alleged untrue statement of a material fact contained in any registration statement or prospectus, or in any amendment or supplement thereto, or in any preliminary prospectus, or arising out of or based upon any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as the same are based upon information furnished to the Company by or on behalf of Purchaser for use therein.

     (b) In connection with each Demand Registration or Piggyback Registration and each offering of Registrable Securities proposed to be made pursuant to such Demand Registration or Piggyback Registration, Purchaser shall furnish to the Company in writing such information as the Company reasonably requests for use in connection with each applicable registration statement and

prospectus. Purchaser agrees to indemnify, to the full extent permitted by law, the Company, its directors, officers, agents or employees, each Person who controls the Company (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the directors, officers, agents or employees of such controlling Person, from and against any and all Losses, as incurred, arising out of or based upon any untrue or alleged untrue statement of a material fact contained in such registration statement or prospectus or in any amendment or supplement thereto, or in any preliminary prospectus, or arising out of or based upon any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, to the extent, but only to the extent, that such untrue or alleged untrue statement or omission or alleged omission is based upon any information so furnished in writing by or on behalf of Purchaser to the Company expressly for use in such registration statement or prospectus.

     (c) If any Person shall be entitled to indemnity hereunder (an “indemnified party”), such indemnified party shall give prompt notice to the party from which such indemnity is sought (the “indemnifying party”) of any claim or of the commencement of any proceeding with respect to which such indemnified party seeks indemnification or contribution pursuant hereto; provided, that the delay or failure to so notify the indemnifying party shall not relieve the indemnifying party from any obligation or liability except to the extent that the indemnifying party has been prejudiced by such delay or failure. The indemnifying party shall have the right, exercisable by giving written notice to an indemnified party promptly after the receipt of written notice from such indemnified party of such claim or proceeding, to assume, at the indemnifying party’s expense, the defense of any such claim or proceeding, with counsel reasonably satisfactory to such indemnified party; provided, that (i) an indemnified party shall have the right to employ separate counsel in any such claim or 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 unless: (A) the indemnifying party agrees to pay such fees and expenses; (B) the indemnifying party fails promptly to assume the defense of such claim or proceeding or fails to employ counsel reasonably satisfactory to such indemnified party; or (C) the named parties to any proceeding (including impleaded parties) include both such indemnified party and the indemnifying party, and such indemnified party shall have been advised by counsel that there may be one or more legal defenses available to it that are inconsistent with those available to the indemnifying party or that a conflict of interest is likely to exist among such indemnified party and any other indemnified parties (in which case the indemnifying party shall not have the right to assume the defense of such action on behalf of such indemnified party); and (ii) subject to clause (C) above, the indemnifying party shall not, in connection with any one such claim or proceeding or separate but substantially similar or related claims or proceedings in the same jurisdiction, arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one firm of attorneys (together with appropriate local counsel) at any time for all of the indemnified parties, or for fees and expenses that are not reasonable. Whether or not such defense is assumed by the indemnifying party, such indemnified party shall not be subject to any liability for any settlement made without its consent. The indemnifying party shall not 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, in form and substance reasonably satisfactory to the indemnified party, from all liability in respect of such claim or litigation for which such indemnified party would be entitled to indemnification hereunder.

     (d) If the indemnification provided for in this Section 2.9 is unavailable to an indemnified party in respect of any Losses (other than in accordance with its terms), then each applicable 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, on the one hand, and such indemnified party, on the other hand, 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, on the one

hand, and indemnified party, on the other hand, shall be determined by reference to, among other things, whether any action in question, including any untrue statement of a material fact or omission or alleged omission to state a material fact, has been taken 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 any such action, statement or omission. The amount paid or payable by a party as a result of any Losses shall be deemed to include any legal or other fees or expenses incurred by such party in connection with any investigation or proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 2.9(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 second immediately preceding sentence. Notwithstanding the provisions of this Section 2.9(d), Purchaser shall not be required to contribute any amount which is in excess of the amount by which the total proceeds received by Purchaser from the sale of the Registrable Securities (net of all underwriting discounts and commissions) exceeds the amount of any damages that such indemnifying party 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.

     Section 2.10 Rule 144. The Company shall use its reasonable best efforts to file in a timely fashion all reports and other documents required to be filed by it under the Securities Act and the Exchange Act and that it will take such further action as Purchaser may reasonably request, all to the extent required from time to time to enable Purchaser to sell Registrable Securities without registration under the Securities Act pursuant to (i) Rule 144 or (ii) any similar rule or regulation hereafter adopted by the Commission. Upon the request of Purchaser, the Company will deliver to Purchaser a written statement as to whether it has complied with such requirements.
