REGISTRATION RIGHTS

Section 2.01. Demand Registration. (a) If at any time the Company shall receive a request from FP; or

(b) if at any time (but only once and provided the right in subsection (c) below has not previously been exercised) during the period beginning on June 29, 2008 and ending on December 29, 2009, the Company shall receive a request from Xxxxxx Xxxxxxxxxx as agent for the Xxxxxx Stockholders; or

(c) if at any time following the later of (i) December 29, 2006 and (ii) the day Xxxxxx Xxxxxxxxxx becomes a Non-Employee (as defined herein) (but only once, and provided the right in subsection (b) above has not been exercised, and provided further that Xxxxxx Xxxxxxxxxx has ceased to be (A) an employee or (B) a director, provided that he has not ceased to be a director either because he was not elected by the Company's stockholders after having been nominated to stand for election or because he declined to stand for election (in either A or B, a “Non-Employee”), of the Company) at any time during the period beginning on the date hereof and ending on June 28, 2008, the Company shall receive a request from Xxxxxx Xxxxxxxxxx as agent for the Xxxxxx Stockholders that the Company effect the registration under the Securities Act of all or any portion of such Requesting Stockholder’s Registrable Securities (provided however, that any sales made pursuant to a request under Section 2.01(c) may only be effected up to the maximum number of shares that may be sold pursuant to Section 3 of the Lockup Agreement), and specifying the intended method of disposition thereof, then the Company shall promptly give notice of such requested registration (each such request shall be referred to herein as a “Demand Registration”) at least 15 Business Days prior to the anticipated filing date of the registration statement relating to such Demand Registration to the other Stockholders and thereupon shall use all reasonable efforts to effect, as expeditiously as possible, the registration under the Securities Act of:

(i) all Registrable Securities for which the Requesting Stockholder has requested registration under this Section 2.01, and

(ii) subject to the restrictions set forth in Sections 2.01(g) and 2.02, all other Registrable Securities of the same class as those requested to be registered by the Requesting Stockholder that any other Stockholders with rights to request registration under Section 2.02 (all such Stockholders, together with the Requesting Stockholder, the “Registering Stockholders”) have requested the Company to register by request received by the Company within 15 Business Days after such Stockholders receive the Company’s notice of the Demand Registration,

all to the extent necessary to permit the disposition (in accordance with the intended methods thereof as aforesaid) of the Registrable Securities so to be registered, provided that the Company shall not be obligated to effect a Demand Registration unless the aggregate gross proceeds expected to be received from the sale of the Registrable Securities requested to be included in such Demand Registration equals or exceeds $5,000,000, and provided, further, that the Company shall not be required to effect a Demand Registration pursuant to subsection (b) hereof pursuant to Rule 415 (or its successor provision) and provided, further, that a registration pursuant to subsection (c) shall be, if so requested, pursuant to Rule 415 (or its successor provision) under the Securities Act. In no event shall the Company be required to effect more than one Demand Registration hereunder within any ninety day period.

(d) Promptly after the expiration of the 15-Business Day period referred to in Section 2.01(c)(ii), the Company will notify all Registering Stockholders of the identities of the other Registering Stockholders and the number of shares of Registrable Securities requested to be included therein. At any time prior to the effective date of the registration statement relating to such registration, the Requesting Stockholders may revoke such request, without liability to any of the other Registering Stockholders, by providing a notice to the Company revoking such request.

(e) The Company shall be liable for and pay all Registration Expenses in connection with any Demand Registration, regardless of whether such Registration is effected.

(f) A Demand Registration shall not be deemed to have occurred:

(i) unless the registration statement relating thereto (A) has become effective under the Securities Act and (B) has remained effective for a period of at least 180 days (or such shorter period in which all Registrable Securities of the Registering Stockholders included in such registration have actually been sold thereunder), provided that such registration statement shall not be considered a Demand Registration if, after such registration statement becomes effective, (1) such registration

statement is interfered with by any stop order, injunction or other order or requirement of the SEC or other governmental agency or court and (2) less than 75% of the Registrable Securities included in such registration statement have been sold thereunder; or

(ii) if the Maximum Offering Size is reduced in accordance with Section 2.01(g) such that less than 66²/₃% of the Registrable Securities of the Requesting Stockholders sought to be included in such registration are included.

(g) If a Demand Registration involves an underwritten Public Offering and the managing underwriter advises the Company and the Requesting Stockholders that, in its view, the number of shares of Registrable Securities requested to be included in such registration (including any securities that the Company proposes to be included that are not Registrable Securities) exceeds the largest number of shares that can be sold without having an adverse effect on such offering, including the price at which such shares can be sold (the “Maximum Offering Size”), the Company shall include in such registration, in the priority listed below, up to the Maximum Offering Size:

     (i) First, all Registrable Securities requested to be registered by the Requesting Stockholder;

     (ii) second, all other Registrable Securities requested to be included in such registration by any Registering Stockholder (allocated, if necessary for the offering not to exceed the Maximum Offering Size, pro rata among such other Stockholders on the basis of the relative number of Registrable Securities so requested to be included in such registration by each such Stockholder); and

     (iii) third, any securities proposed to be registered by the Company.

(h) Upon notice to each Requesting Stockholder, the Company may postpone effecting a registration pursuant to this Section 2.01 on one occasion during any period of twelve consecutive months for a reasonable time specified in the notice but not exceeding 60 days (which period may not be extended or renewed), if (i) an investment banking firm of recognized national standing shall advise the Company and the Requesting Stockholders in writing that effecting the registration would materially and adversely affect an offering of securities of such Company the preparation of which had then been commenced or (ii) the Company is in possession of material non-public information the disclosure of which during the period specified in such notice the Company reasonably believes would not be in the reasonable interests of the Company.

Section 2.02. Piggyback Registration. (a) If at any time the Company proposes to register any Company Securities under the Securities Act (other than

a registration on Form S-8 or S-4, or any successor forms, relating to Common Stock issuable upon exercise of employee stock options or in connection with any employee benefit or similar plan of the Company or in connection with a direct or indirect acquisition by the Company of another Person), whether or not for sale for its own account, the Company shall each such time give notice at least 30 Business Days prior to the anticipated filing date of the registration statement relating to such registration to each Stockholder, which notice shall set forth such Stockholder’s rights under this Section 2.02 and shall offer such Stockholder the opportunity to include in such registration statement the number of Registrable Securities of the same class or series as those proposed to be registered as each such Stockholder may request (a “Piggyback Registration”), subject to the provisions of Section 2.02(b) . Upon the request of any such Stockholder made within 15 Business Days after the receipt of notice from the Company (which request shall specify the number of Registrable Securities intended to be registered by such Stockholder), the Company shall use its reasonable efforts to effect the registration under the Securities Act of all Registrable Securities that the Company has been so requested to register by all such Stockholders, to the extent requisite to permit the disposition of the Registrable Securities to be so registered, provided that (i) if such registration involves an underwritten Public Offering, all such Stockholders requesting to be included in the Company’s registration must sell their Registrable Securities to the underwriters selected as provided herein on the same terms and conditions as apply to the Company or the Requesting Stockholders, as applicable, and (ii) if, at any time after giving notice of its intention to register any Company Securities pursuant to this Section 2.02(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 all such Stockholders and, thereupon, shall be relieved of its obligation to register any Registrable Securities in connection with such registration. No registration effected under this Section 2.02 shall relieve the Company of its obligations to effect a Demand Registration to the extent required by Section 2.01. The Company shall pay all Registration Expenses in connection with each Piggyback Registration.

(b) If a Piggyback Registration involves an underwritten Public Offering (other than any Demand Registration, in which case the provisions with respect to priority of inclusion in such offering set forth in Section 2.01(g) shall apply) and the managing underwriter advises the Company that, in its view, the number of Shares that the Company and such Stockholders intend to include in such registration exceeds the Maximum Offering Size, the Company shall include in such registration, in the following priority, up to the Maximum Offering Size:

(i) first, so much of the Company Securities proposed to be registered for the account of the Company as would not cause the offering to exceed the Maximum Offering Size; and

(ii) second, all Registrable Securities requested to be included in such registration by any other Stockholders pursuant to Section 2.02 (allocated, if necessary for the offering not to exceed the Maximum Offering Size, pro rata among such Stockholders on the basis of the relative number of shares of Registrable Securities so requested to be included in such registration by each).

Section 2.03. Registration Procedures. Whenever Stockholders request that any Registrable Securities be registered pursuant to Section 2.01 or 2.02, subject to the provisions of such Sections, the Company shall use its reasonable efforts to effect the registration and the sale of such Registrable Securities in accordance with the intended method of disposition thereof as quickly as practicable, and, in connection with any such request:

(a) The Company shall as expeditiously as possible prepare and file with the SEC a registration statement on any form for which the Company then qualifies or that counsel for the Company shall deem appropriate and which form shall be available for the sale of the Registrable Securities to be registered thereunder in accordance with the intended method of distribution thereof, and use its reasonable efforts to cause such filed registration statement to become and remain effective for a period of not less than 180 days, or in the case of a shelf registration statement, one year (or such shorter period in which all of the Registrable Securities of the Registering Stockholders included in such registration statement shall have actually been sold thereunder).

(b) Prior to filing a registration statement or prospectus or any amendment or supplement thereto, the Company shall, if requested, furnish to each participating Stockholder and each underwriter, if any, of the Registrable Securities covered by such registration statement copies of such registration statement as proposed to be filed, and thereafter the Company shall furnish to such Stockholder and underwriter, if any, such number of copies of such registration statement, each amendment and supplement thereto (in each case including all exhibits thereto and documents incorporated by reference therein), the prospectus included in such registration statement (including each preliminary prospectus and any summary prospectus) and any other prospectus filed under Rule 424 or Rule 430A under the Securities Act and such other documents as such Stockholder or underwriter may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such Stockholder. Each participating Stockholder shall have the right to request that the Company modify any information contained in such registration statement, amendment and supplement thereto pertaining to such Stockholder and the Company shall use its reasonable efforts to comply with such request, provided, however, that the Company shall not have any obligation to so modify any information if the Company reasonably expects that so doing would cause the prospectus to contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading.

(c) After the filing of the registration statement, the Company shall (i) cause the related prospectus to be supplemented by any required prospectus supplement, and, as so supplemented, to be filed pursuant to Rule 424 under the Securities Act, (ii) comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities covered by such registration statement during the applicable period in accordance with the intended methods of disposition by the Registering Stockholders thereof set forth in such registration statement or supplement to such prospectus and (iii) promptly notify each Registering Stockholder holding Registrable Securities covered by such registration statement of any stop order issued or threatened by the SEC or any state securities commission and take all reasonable actions required to prevent the entry of such stop order or to remove it if entered.

(d) The Company shall use its reasonable efforts to (i) register or qualify the Registrable Securities covered by such registration statement under such other securities or “blue sky” laws of such jurisdictions in the United States as any Registering Stockholder holding such Registrable Securities reasonably (in light of such Stockholder’s intended plan of distribution) requests and (ii) cause such Registrable Securities to be registered with or approved by such other governmental agencies or authorities as may be necessary by virtue of the business and operations of the Company and do any and all other acts and things that may be reasonably necessary or advisable to enable such Stockholder to consummate the disposition of the Registrable Securities owned by such Stockholder, provided that the Company shall not be required to (A) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this Section 2.03(d), (B) subject itself to taxation in any such jurisdiction or (C) consent to general service of process in any such jurisdiction.

(e) The Company shall immediately notify each Registering Stockholder holding such Registrable Securities covered by such registration statement, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of the occurrence of an event requiring the preparation of a supplement or amendment to such prospectus so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus will not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading and promptly prepare and make available to each such Stockholder and file with the SEC any such supplement or amendment.

(f) (i) FP shall have the right, in its sole discretion, to select an underwriter or underwriters in connection with any Public Offering resulting from the exercise by FP of a Demand Registration, which underwriter or underwriters may include any Affiliate of FP and (ii) the Company shall select an underwriter or underwriters in connection with any other Public Offering, which underwriter or underwriters shall be reasonably acceptable to the Requesting Stockholder. In

connection with any Public Offering, the Company shall enter into customary agreements (including an underwriting agreement in customary form) and take such all other actions as are required in order to expedite or facilitate the disposition of such Registrable Securities in any such Public Offering, including the engagement of a “qualified independent underwriter” in connection with the qualification of the underwriting arrangements with the NASD.

(g) Upon execution of confidentiality agreements in form and substance reasonably satisfactory to the Company, the Company shall make available for inspection by any Registering Stockholder and any underwriter participating in any disposition pursuant to a registration statement being filed by the Company pursuant to this Section 2.03 and any attorney, accountant or other professional retained by any such Stockholder or underwriter (collectively, the “Inspectors”), all financial and other records, pertinent corporate documents and properties of the Company (collectively, the “Records”) as shall be reasonably necessary or desirable to enable them to exercise their due diligence responsibility, and cause the Company’s officers, directors and employees to supply all information reasonably requested by any Inspectors in connection with such registration statement. Records that the Company determines, in good faith, to be confidential and that it notifies the Inspectors are confidential shall not be disclosed by the Inspectors unless (i) the disclosure of such Records is necessary to avoid or correct a misstatement or omission in such registration statement or (ii) the release of such Records is ordered pursuant to a subpoena or other order from a court of competent jurisdiction. Each Registering Stockholder agrees that information obtained by it as a result of such inspections shall be deemed confidential and shall not be used by it or its Affiliates as the basis for any market transactions in the Company Securities unless and until such information is made generally available to the public. Each Registering Stockholder further agrees that, upon learning that disclosure of such Records is sought in a court of competent jurisdiction, it shall give notice to the Company and allow the Company, at its expense, to undertake appropriate action to prevent disclosure of the Records deemed confidential.

(h) The Company shall furnish to each Registering Stockholder and to each such underwriter, if any, a signed counterpart, addressed to such Stockholder or underwriter, of (i) an opinion or opinions of counsel to the Company and (ii) a comfort letter or comfort letters from the Company’s independent public accountants, each in customary form and covering such matters of the kind customarily covered by opinions or comfort letters, as the case may be, as a majority of such Stockholders or the managing underwriter therefor reasonably requests.

(i) The Company shall otherwise use its 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 or such other document covering a period of 12 months, beginning within three months

after the effective date of the registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder.

(j) The Company may require each such Registering Stockholder promptly to furnish in writing to the Company such information regarding the distribution of the Registrable Securities as the Company may from time to time reasonably request and such other information as may be legally required in connection with such registration.

(k) Each such Registering Stockholder agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 2.03(e), such Stockholder shall forthwith discontinue disposition of Registrable Securities pursuant to the registration statement covering such Registrable Securities until such Stockholder’s receipt of the copies of the supplemented or amended prospectus contemplated by Section 2.03(e), and, if so directed by the Company, such Stockholder shall deliver to the Company all copies, other than any permanent file copies then in such Stockholder’s possession, of the most recent prospectus covering such Registrable Securities at the time of receipt of such notice. If the Company shall give such notice, the Company shall extend the period during which such registration statement shall be maintained effective (including the period referred to in Section 2.03(a)) by the number of days during the period from and including the date of the giving of notice pursuant to Section 2.03(e) to the date when the Company shall make available to such Stockholder a prospectus supplemented or amended to conform with the requirements of Section 2.03(e).

(l) The Company shall use its reasonable efforts to list all Registrable Securities covered by such registration statement on any securities exchange or quotation system on which any of the Registrable Securities are then listed or traded.

(m) The Company shall have appropriate officers of the Company (i) prepare and make presentations at any “road shows” and before analysts and rating agencies, as the case may be, (ii) take other actions to obtain ratings for any Registrable Securities and (iii) otherwise use their reasonable efforts to cooperate as reasonably requested by the underwriters in the offering, marketing or selling of the Registrable Securities.

Section 2.04. Indemnification by the Company. The Company agrees to indemnify and hold harmless each Registering Stockholder holding Registrable Securities covered by a registration statement, its officers, directors, employees, partners and agents, and each Person, if any, who controls such Stockholder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages, liabilities and expenses (including reasonable expenses of investigation and reasonable

attorneys’ fees and expenses) (“Damages”) caused by or relating to any untrue statement or alleged untrue statement of a material fact contained in any registration statement or prospectus relating to the Registrable Securities (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto) or any preliminary prospectus, or caused by or relating to any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such Damages are caused by or related to any such untrue statement or omission or alleged untrue statement or omission so made based upon information furnished in writing to the Company by such Stockholder or on such Stockholder’s behalf expressly for use therein, provided that, with respect to any untrue statement or omission or alleged untrue statement or omission made in any preliminary prospectus, or in any prospectus, as the case may be, the indemnity agreement contained in this paragraph shall not apply to the extent that any Damages result from the fact that a current copy of the prospectus (or such amended or supplemented prospectus, as the case may be) was not sent or given to the Person asserting any such Damages at or prior to the written confirmation of the sale of the Registrable Securities concerned to such Person if it is determined that the Company has provided such prospectus to such Stockholder and it was the responsibility of such Stockholder to provide such Person with a current copy of the prospectus (or such amended or supplemented prospectus, as the case may be) and such current copy of the prospectus (or such amended or supplemented prospectus, as the case may be) would have cured the defect giving rise to such Damages. The Company also agrees to indemnify any underwriters of the Registrable Securities, their officers and directors and each Person who controls such underwriters within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act on substantially the same basis as that of the indemnification of the Stockholders provided in this Section 2.04.

Section 2.05. Indemnification by Participating Stockholders. Each Registering Stockholder holding Registrable Securities included in any registration statement agrees, severally but not jointly, to indemnify and hold harmless the Company, its officers, directors and agents and each Person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company to such Stockholder, but only (i) with respect to information furnished in writing by such Stockholder or on such Stockholder’s behalf expressly for use in any registration statement or prospectus relating to the Registrable Securities, or any amendment or supplement thereto, or any preliminary prospectus or (ii) to the extent that any Damages result from the fact that a current copy of the prospectus (or such amended or supplemented prospectus, as the case may be) was not sent or given to the Person asserting any such Damages at or prior to the written confirmation of the sale of the Registrable Securities concerned to such Person if it is determined that it was the responsibility of such Stockholder to provide such Person with a current copy of the prospectus (or such amended or supplemented prospectus, as the case may be)

and such current copy of the prospectus (or such amended or supplemented prospectus, as the case may be) would have cured the defect giving rise to such loss, claim, damage, liability or expense. Each such Stockholder also agrees to indemnify and hold harmless underwriters of the Registrable Securities, their officers and directors and each Person who controls such underwriters within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act on substantially the same basis as that of the indemnification of the Company provided in this Section 2.05. As a condition to including Registrable Securities in any registration statement filed in accordance with Article 2, the Company may require that it shall have received an undertaking reasonably satisfactory to it from any underwriter to indemnify and hold it harmless to the extent customarily provided by underwriters with respect to similar securities. No Registering Stockholder shall be liable under this Section 2.05 for any Damages in excess of the net proceeds realized by such Stockholder in the sale of Registrable Securities of such Stockholder to which such Damages relate.

Section 2.06. Conduct of Indemnification Proceedings. If any proceeding (including any governmental investigation) shall be instituted involving any Person in respect of which indemnity may be sought pursuant to this Article 2, such Person (an “Indemnified Party”) shall promptly notify the Person against whom such indemnity may be sought (the “Indemnifying Party”) in writing and the Indemnifying Party shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such Indemnified Party, and shall assume the payment of all fees and expenses, provided that the failure of any Indemnified Party so to notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure to notify. In any such proceeding, any Indemnified Party 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 Party unless (i) the Indemnifying Party and the Indemnified Party shall have mutually agreed to the retention of such counsel or (ii) in the reasonable judgment of such Indemnified Party representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that, in connection with any proceeding or related proceedings in the same jurisdiction, the Indemnifying Party shall not be liable for the reasonable fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) at any time for all such Indemnified Parties, and that all such fees and expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Indemnified Parties, such firm shall be designated in writing by the Indemnified Parties. The Indemnifying Party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent, or if there be a final judgment for the plaintiff, the Indemnifying Party shall indemnify and hold harmless such Indemnified Parties from and against any loss or liability (to the extent stated above) by reason of such settlement or judgment. Without the prior written consent of the Indemnified Party, no Indemnifying Party shall effect any

settlement of any pending or threatened proceeding in respect of which any Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified Party from all liability arising out of such proceeding.

Section 2.07. Contribution. If the indemnification provided for in this Article 2 is unavailable to the Indemnified Parties in respect of any Damages, then each such 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 Damages (i) as between the Company and the Registering Stockholders holding Registrable Securities covered by a registration statement on the one hand and the underwriters on the other, in such proportion as is appropriate to reflect the relative benefits received by the Company and such Stockholders on the one hand and the underwriters on the other, from the offering of the Registrable Securities, or if such allocation is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits but also the relative fault of the Company and such Stockholders on the one hand and of such underwriters on the other in connection with the statements or omissions that resulted in such Damages, as well as any other relevant equitable considerations and (ii) as between the Company on the one hand and each such Stockholder on the other, in such proportion as is appropriate to reflect the relative fault of the Company and of each such Stockholder in connection with such statements or omissions, as well as any other relevant equitable considerations. The relative benefits received by the Company and such Stockholders on the one hand and such underwriters on the other shall be deemed to be in the same proportion as the total proceeds from the offering (net of underwriting discounts and commissions but before deducting expenses) received by the Company and such Stockholders bear to the total underwriting discounts and commissions received by such underwriters, in each case as set forth in the table on the cover page of the prospectus. The relative fault of the Company and such Stockholders on the one hand and of such underwriters on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company and such Stockholders or by such underwriters. The relative fault of the Company on the one hand and of each such Stockholder on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by such party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Registering Stockholders agree that it would not be just and equitable if contribution pursuant to this Section 2.07 were determined by pro rata allocation (even if the underwriters were treated as one entity for such

purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an Indemnified Party as a result of the Damages referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 2.07, no underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Registrable Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any Damages that such underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission, and no Registering Stockholder shall be required to contribute any amount in excess of the amount by which the total price at which the Registrable Securities of such Stockholder were offered to the public (less underwriters’ discounts and commissions) exceeds the amount of any Damages that such Stockholder 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. Each Registering Stockholder’s obligation to contribute pursuant to this Section 2.07 is several in the proportion that the proceeds of the offering received by such Stockholder bears to the total proceeds of the offering received by all such Registering Stockholders and not joint.

Section 2.08. Participation in Public Offering. No Person may participate in any Public Offering hereunder unless such Person (a) agrees to sell such Person’s securities on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements and (b) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements and the provisions of this Agreement in respect of registration rights.

Section 2.09. Other Indemnification. Indemnification similar to that specified herein (with appropriate modifications) shall be given by the Company and each Registering Stockholder participating therein with respect to any required registration or other qualification of securities under any federal or state law or regulation or governmental authority other than the Securities Act.

Section 2.10. Cooperation by the Company. If any Stockholder shall transfer any Registrable Securities pursuant to Rule 144, the Company shall cooperate, to the extent commercially reasonable, with such Stockholder and shall provide to such Stockholder such information as such Stockholder shall reasonably request.

Section 2.11. No Transfer of Registration Rights. None of the rights of Stockholders under this Article 2 shall be assignable by any Stockholder to any Person acquiring Securities in any Public Offering or pursuant to Rule 144.

The Company also represents and warrants to each Stockholder that it has not previously entered into any agreement with respect to any of its securities granting any registration rights to any Person other than the Original Registration Rights Agreement.
