Section 3.2 If the Shelf Registration Statement or any Subsequent Shelf Registration Statement ceases to be effective for any reason at any time during the Effectiveness Period (other than because all Registrable Securities registered thereunder shall have been resold pursuant thereto or shall have otherwise ceased to be Registrable Securities), the Company shall

use its reasonable best efforts to obtain the prompt withdrawal of any order suspending the effectiveness thereof or file an additional Shelf Registration Statement covering all of the securities that as of the date of such filing are Registrable Securities (a “Subsequent Shelf Registration Statement”). If a Subsequent Shelf Registration Statement is filed, the Company shall use its reasonable best efforts to cause the Subsequent Shelf Registration Statement to become effective as promptly as is practicable after such filing and to keep such Subsequent Shelf Registration Statement (or other Subsequent Shelf Registration Statement) continuously effective until the end of the Effectiveness Period.

Section 3.4 The Company shall use its reasonable best efforts to, on a timely basis, supplement and amend the Shelf Registration Statement or any Subsequent Shelf Registration Statement if required by the rules, regulations or instructions applicable to the registration form used by the Company for such Shelf Registration Statement or any Subsequent Shelf Registration Statement, if required by the Securities Act or as reasonably requested by any Holder covered by such Shelf Registration Statement.

Section 3.5 Each Holder agrees that if such Holder wishes to sell Registrable Securities pursuant to a Shelf Registration Statement or a Subsequent Shelf Registration Statement and related Prospectus, it will do so in accordance with this Section 3.5 and Section 4.2. Each Holder wishing to sell Registrable Securities pursuant to a Shelf Registration Statement or any Subsequent Shelf Registration Statement and related Prospectus agrees to deliver a Notice and Questionnaire to the Company at least ten Business Days prior to any intended distribution of Registrable Securities under the Shelf Registration Statement or a Subsequent Shelf Registration Statement. From and after the date the Shelf Registration Statement or a Subsequent Shelf Registration Statement is declared effective the Company shall, as promptly as practicable after the date a Notice and Questionnaire is delivered to it, and in any event upon the later of (x) ten Business Days after such date (but no earlier than tenth Business Days after effectiveness) or (y) ten Business Days after the expiration of any Suspension Period in effect when the Notice and Questionnaire is delivered or put into effect within five Business Days of such delivery date:

(a) if required by applicable law, file with the SEC a post-effective amendment to the Shelf Registration Statement or prepare and, if required by applicable law, file a supplement to the related Prospectus or a supplement or amendment to any document incorporated therein by reference or file any other required document so that the Holder delivering such Notice and Questionnaire is named as a selling securityholder in the Shelf Registration Statement and the related Prospectus in such a manner as to permit such Holder to deliver such Prospectus to purchasers of Registrable Securities in accordance with applicable law and, if the Company shall file a post-effective

amendment to the Shelf Registration Statement, use its reasonable best efforts to cause such post-effective amendment to be declared effective under the Securities Act as promptly as is practicable;

(b) provide such Holder copies of any documents filed pursuant to Section 3.5(a); and

(c) notify such Holder as promptly as practicable after the effectiveness under the Securities Act of any post-effective amendment filed pursuant to Section 3.5(a);

Notwithstanding anything contained herein to the contrary, the Company shall be under no obligation to name any Holder that has not delivered a Notice and Questionnaire to the Company as a selling securityholder in any Shelf Registration Statement or related Prospectus.

SECTION 4. REGISTRATION PROCEDURES.

Section 4.1 In connection with the Shelf Registration Statement or any Subsequent Shelf Registration Statement, the Company shall comply with all the provisions of Section 4.2 hereof and shall use its reasonable best efforts to effect such registration in accordance with the terms hereof to permit the resale of the Registrable Securities.

Section 4.2 In connection with the Shelf Registration Statement or any Subsequent Shelf Registration Statement required by this Agreement, the Company shall:

(a) Use its reasonable best efforts to keep the registration statement continuously effective during the Effectiveness Period; upon the occurrence of any event that would cause the registration statement or the Prospectus contained therein (i) to contain a material misstatement or omission or (ii) not to be effective and usable for resale of Registrable Securities during the Effectiveness Period, the Company shall file promptly an appropriate amendment to the registration statement, a supplement to the Prospectus or a report filed with the SEC pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act, in the case of clause (i), correcting any such misstatement or omission, and, in the case of either clause (i) or (ii), use its reasonable best efforts to cause such amendment to be declared effective and the registration statement and the related Prospectus to become usable for their intended purposes as soon as practicable thereafter.

(b) Notwithstanding Section 4.2(a) hereof, the Company may suspend the effectiveness of the Shelf Registration Statement or any Subsequent Shelf Registration (each such period, a “Suspension Period”) if the Company reasonably determines and delivers to the Holder a notice stating that either (i) such Shelf Registration Statement or any Subsequent Shelf Registration contains an untrue statement

of a material fact or omits to state any material fact necessary to make the statements therein not misleading in light of the circumstance then existing and the disclosure of the information required to correct such misstatement or omission at such time would be adverse in any significant respect to the Company or (ii) the filing or continued use of the registration statement would require the Company to disclose a material financing, acquisition or other corporate development which has not been, and would not otherwise be required to be, disclosed to the public and such disclosure at such time would be adverse in any significant respect to the Company. Upon such suspension, the Company shall give notice to the Holders listed in such Shelf Registration Statement or Subsequent Shelf Registration Statement that the availability of the registration statement is suspended and, upon actual receipt of such notice, each Holder agrees not to sell any Registrable Securities pursuant to the registration statement until the earlier of (A) such Holder’s receipt of copies of the supplemented or amended Prospectus provided for in Section 4.2 hereof or (B) such Holder has been advised in writing by the Company that the sale of Registrable Securities pursuant to the registration statement may resume. The Suspension Period shall not exceed 60 consecutive days or an aggregate of 120 days in any 360-day period. Except as set forth above, the Company shall not be required to specify in the written notice to the Holders the nature of the event giving rise to the Suspension Period.

(c) Prepare and file with the SEC such amendments and post-effective amendments to the Shelf Registration Statement and any Subsequent Shelf Registration Statement as may be necessary to keep the registration statement effective during the Effectiveness Period.

(d) Advise any Holder that has provided in writing to the Company a telephone or facsimile number and address for notice, promptly and, if requested by such Holder, to confirm such advice in writing (which notice pursuant to clauses (ii) through (iv) below shall be accompanied by an instruction to suspend the use of the Prospectus until the Company shall have remedied the basis for such suspension):

(i) when the Prospectus or any Prospectus supplement or post-effective amendment has been filed, and, with respect to the registration statement or any post-effective amendment thereto, when the same has become effective,

(ii) of any request by the SEC for amendments to the registration statement or amendments or supplements to the Prospectus or for additional information relating thereto,

(iii) of the issuance by the SEC of any stop order suspending the effectiveness of the registration statement under the Securities Act or of the suspension by any state securities commission of the qualification of the Registrable Securities for offering or sale in any jurisdiction, or the threatening or initiation of any proceeding for any of the preceding purposes, or

(iv) of the existence of any fact or the happening of any event, during the Effectiveness Period, that makes any statement of a material fact made in the registration statement, the Prospectus, any amendment or supplement thereto, or any document incorporated by reference therein untrue, or that requires the making of any additions to or changes in the registration statement or the Prospectus in order to make the statements therein not misleading.

(e) If requested by any Holder, promptly incorporate in the registration statement or Prospectus, pursuant to a supplement or post-effective amendment if necessary, such information as such Holders may reasonably request to have included therein, including, without limitation, information relating to the “Plan of Distribution” of the Registrable Securities.

(f) Unless any Registrable Securities shall be in book-entry form only, cooperate with the Holders to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be sold and not bearing any restrictive legends (unless required by applicable securities laws); and enable such Registrable Securities to be in such denominations and registered in such names as the Holders may request at least two Business Days before any sale of Registrable Securities.

Section 4.3 Each Holder agrees by acquisition of a Registrable Security, that no Holder shall be entitled to sell any of such Registrable Securities pursuant to a Shelf Registration Statement or any Subsequent Shelf Registration Statement, or to receive a Prospectus relating thereto, unless such Holder has furnished the Company with a Notice and Questionnaire as required pursuant to Section 3.5 hereof (including the information required to be included in such Notice and Questionnaire) and the information set forth in the next sentence. The Company may require each Holder of Common Stock to be sold pursuant to the Shelf Registration Statement or any Subsequent Shelf Registration Statement to furnish to the Company such information regarding the Holder and the distribution of such Common Stock as the Company may from time to time reasonably require for inclusion in such Shelf Registration Statement or Subsequent Shelf Registration Statement. Each such Holder agrees promptly to furnish to the Company all information required to be disclosed in order to make the information previously furnished to the Company by such Holder not misleading and any other information regarding such Holder and the distribution of such Registrable Securities as the Company may from time to time reasonably request in writing. Any sale of any Registrable Securities by any Holder shall constitute a representation and warranty by such Holder that the information relating to such Holder and its Plan of Distribution is as set forth in the Prospectus delivered by such Holder in connection with such disposition, that such Prospectus does not as of the time of such sale contain any untrue statement of a material fact relating to or provided by such Holder or its Plan of Distribution and that such Prospectus does not as of the time of such sale omit to state any material fact relating to or provided by such Holder or its Plan of Distribution necessary to make the statements in such Prospectus, in the light of the circumstances under which they were made not misleading. The Company may exclude from such Shelf Registration Statement or any Subsequent Shelf Registration Statement the Registrable Securities of any Holder that fails to furnish such information within a reasonable time after receiving such request. The Company shall not include in any registration statement any information regarding, relating to,

or referring to any Holder or its Plan of Distribution without the approval of such Holder in writing (not to be unreasonably withheld).

SECTION 5. REGISTRATION EXPENSES.

Section 5.1 All expenses incident to the Company’s performance of or compliance with this Agreement, including without limitation all fees and expenses of compliance with securities or blue sky laws, messenger, telephone and delivery expenses, and fees and disbursements of counsel for the Company and of the Company’s independent certified public accountants (but excluding (i) registration fees payable in connection with the filing of the Shelf Registration Statement and any subsequent Shelf Registration Statement (which shall be reimbursed by the Holders listed in such Shelf Registration Statement or Subsequent Shelf Registration Statement pro rata) (ii) all fees and disbursements of counsel for the Holders, (iii) all underwriting discounts or other commissions, fees, discounts and commissions of brokers and dealers and (iv) capital gains, income and transfer taxes, if any, relating to any sale of Registrable Securities) will be borne and paid promptly by the Company (all such expenses being herein called “Registration Expenses”).

SECTION 6. INDEMNIFICATION; CONTRIBUTION.

Section 6.1 Indemnification by the Company. In the event any Registrable Securities are included in a registration statement pursuant to this Agreement, the Company shall indemnify and hold harmless each Holder, its Affiliates, employees, officers, directors, agents and constituent partners (within the meaning of the Securities Act and the Exchange Act) against all losses, claims, damages, liabilities (joint or several) and expenses (or actions in respect thereof) in connection with any sale of Registrable Securities pursuant to a registration statement arising out of or based upon (i) any violation or alleged violation of the Securities Act or any rule or regulation promulgated thereunder by the Company or any of its Affiliates, employees, officers, directors or agents or (ii) any untrue or alleged untrue statement of a material fact contained in any registration statement or preliminary or final prospectus relating to the registration of such Registrable Securities or any amendment or supplement thereto or any document incorporated by reference therein or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, except insofar as the same are contained in any information furnished in writing to the Company by or on behalf of such Holder or other indemnified Person expressly for use therein or are caused by such Holder’s failure to deliver a copy of the registration statement or prospectus or any amendments or supplements thereto after the Company has furnished such Holder with a sufficient number of copies of the

same. Subject to Section 6.3, the Company will pay, indemnify, hold harmless and reimburse each Holder and its Affiliates, officers, directors, agents, and constituent partners for any reasonable legal and other expenses as incurred in connection with investigating or defending any such losses, claims, damages, liabilities, expenses or actions for which such Person is entitled to indemnification hereunder.

Section 6.2 Indemnification by Holder of Registrable Securities. In connection with any registration statement in which a Holder is participating, such Holder shall indemnify and hold harmless the Company, its employees, directors, agents and officers, each Person who controls the Company (within the meaning of the Securities Act and the Exchange Act) and all other prospective sellers and their respective directors, officers, agents and controlling Persons (within the meaning of the Securities Act and the Exchange Act) against any losses, claims, damages, liabilities (joint and several) and expenses (or actions in respect thereof) arising out of or based upon any untrue or alleged untrue statement of a material fact or any omission or alleged omission of a material fact required to be stated in any registration statement or preliminary or final prospectus relating to the registration of such Registrable Securities or any amendment thereof or supplement thereto or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, to the extent, but only to the extent, that such untrue or alleged untrue statement or omission or alleged omission is contained in any written information or affidavit furnished by or on behalf of such Holder specifically for use in such registration statement or prospectus and then only to the extent of the total net proceeds received by such Holder (after deducting any discounts, commissions and similar fees applicable thereto) in consideration of the Registrable Securities sold by such Holder in connection with such registration. Subject to the provisions of Section 6.3, the Holders participating in any registration will pay, indemnify, hold harmless and reimburse (without duplication), up to the full extent of the total net proceeds received by the Holders (after deducting any discounts, commissions and similar fees applicable thereto and after taking into account any indemnity payments pursuant to the immediately preceding sentence), the Company, its officers, directors and controlling Persons and all other prospective sellers and their respective directors, agents, officers and controlling Persons for any reasonable legal and other expenses as incurred in connection with investigation or defending any such losses, claims, damages, liabilities, expenses or actions.

Section 6.3 Conduct of Indemnification Proceedings. Any Person entitled to indemnification hereunder will (i) give prompt notice to the indemnifying party of any claim with respect to which it seeks indemnification (but omission of such notice shall not relieve the indemnifying party from liability hereunder except to the extent such indemnifying party is actually prejudiced by such failure to give notice) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest may exist between such indemnified and indemnifying parties with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. The indemnifying party will not be subject to any liability for any settlement made without its consent. No indemnifying party will consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of an unconditional release from all liability in respect to such claim or litigation and does not subject the indemnified party to any material injunctive relief or other material equitable remedy. An

indemnifying party who is not entitled to, or elects not to, assume the defense of a claim will not be obligated to pay the fees and expenses of more than one counsel (in addition to any local counsel) for all parties indemnified by such indemnifying party with respect to such claim.

Section 6.4 Contribution. If the indemnification provided for in Section 6.1 or Section 6.2 is unavailable or insufficient to hold harmless each of the indemnified parties against any losses, claims, damages, liabilities and expenses (or actions in respect thereof) to which such parties may become subject under the Securities Act, then the indemnifying party shall, in lieu of indemnifying each party entitled to indemnification hereunder, contribute to the amount paid or payable by such party as a result of such losses, claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and such indemnified parties on the other in connection with the statements or omissions or alleged statements or omissions that resulted in such losses, claims, damages, liabilities or expenses. The relative fault of such parties shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact, or omission or alleged omission to state a material fact, relates to information supplied by or concerning the indemnifying party on the one hand, or by such indemnified party on the other, and such party’s relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 6.4 were determined by pro rata allocation or by any other allocation that does not take into account the equitable considerations referred to in this Section 6.4. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or expenses referred to above shall be deemed to include (subject to the limitations set forth in Section 6.2 or 6.3 hereof) any legal or other fees or expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action, proceeding or claim. Notwithstanding the provisions of this Section 6.4, no seller of Registrable Securities shall be required to contribute any amount in excess of the amount by which the proceeds received by such seller from the sale of any Registrable Securities (after deducting any fees, discounts and commissions applicable thereto) exceeds the amount of any damages which such seller 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 the Act shall be entitled to contribution from any Person that is not guilty of such fraudulent misrepresentation.

SECTION 7. RULE 144.

The Company covenants that it will use its reasonable best efforts to timely file the reports required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted by the SEC thereunder, all to the extent required from time to time to enable such Holder to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by (a) Rule 144 under the Securities Act, as such Rule may be amended from time to time, or (b) any similar rule or regulation hereafter adopted by the SEC. Upon the request of any holder of Registrable Securities, the Company will deliver to such holder a written statement as to whether it has complied with such requirements.

SECTION 8. MISCELLANEOUS.

All notices or other communications provided for hereunder shall be in writing and shall be effective (i) on the day on which delivered if delivered personally or transmitted by facsimile with evidence of receipt, (ii) one business day after the date on which the same is delivered to a nationally recognized overnight courier service with evidence of receipt, or (iii) five days after the date on which the same is deposited, postage prepaid, in the U.S. mail, sent by certified or registered mail, return receipt requested, and addressed to the party to be notified at the address indicated below for the Company, or at the address for the Holder set forth in a registry maintained by the Company or, in the case of a Purchaser, the address set forth on Schedule A to the Purchase Agreement, or at such other address and/or facsimile number and/or to the attention of such other person as the Company or the Holder may designate by ten-day advance written notice.

Section 8.4 Successors and Assigns. This Agreement will inure to the benefit of and be binding upon the successors and permitted assigns of each of the parties. The registration rights granted by this Agreement may not be transferred or assigned by operation of law or in connection with any transfer or assignment of Notes or Registrable Securities to a non-Affiliate of a Holder unless, following such transfer or assignment, such transferee will hold an amount of Registrable Securities, or Notes convertible into an amount of Registrable Securities greater than 2.5% of the Common Stock outstanding on the date of such transfer or assignment, and then only upon notification to the Company in writing and agreement by such transferee to the rights and obligations of this Agreement.
