(a) On or prior to the Filing Deadline, and subject to the availability of Rule 415, the Company shall prepare and file with the Commission a “Shelf” Registration Statement covering the resale of the Registrable Securities for an offering to be made on a continuous basis pursuant to Rule 415. The Registration Statement shall be on Form S-3 (except if the Company is not then eligible to register for resale the Registrable Securities on Form S-3, in which case such registration shall be on another appropriate form in accordance herewith) and shall contain substantially the “Plan of Distribution” attached hereto as Annex A, as modified by the Company as necessary to conform to comments from the Commission. Subject to the terms of this Agreement, the Company shall use its best efforts to cause the Registration Statement to be declared effective under the Securities Act as promptly as possible after the filing thereof, and after the Effective Date, shall use its best efforts to keep such Registration Statement continuously effective under the Securities Act until all Registrable Securities covered by such Registration Statement have been sold, subject, however, to any Allowable Grace Period. The Company agrees to request the Commission for acceleration of effectiveness at 4:00 p.m. Eastern Standard Time on the Effective Date, and by 9:30 a.m. Eastern Standard Time on the Trading Day following the Effective Date, to file a final Prospectus with the Commission pursuant to Rule 424 and notify the Holders via facsimile of effectiveness of the Registration Statement.

(b) If (i) the initial Registration Statement required to be filed by the Company pursuant to this Agreement that covers all of the Registrable Securities is (A) not filed with the Commission on or before the Filing Deadline (if the Company files a Registration Statement without affording the Holders the opportunity to review and comment on the same as required by Section 3(a) hereof, the Company shall not be deemed to have satisfied this clause) (a “Filing Failure”) or (B) not declared effective by the Commission on or before the Effectiveness Deadline (an “Effectiveness Failure”) or (ii) on any day during the Effectiveness Period sales of all of the Registrable Securities cannot be made (other than during an Allowable

3

Grace Period (as defined in Section 3(j)) pursuant to such Registration Statement (including, without limitation, because of a failure to keep such Registration Statement effective, to disclose such information as is necessary for sales to be made pursuant to such Registration Statement, or to register all of the Registrable Securities) (a “Maintenance Failure”) then, as partial relief for the damages to any Holder by reason of any such delay in or reduction of its ability to sell the underlying shares of Common Stock (which remedy shall not be exclusive of any other remedies available at law or in equity), the Company shall pay to each Holder of Registrable Securities an amount in cash equal to one percent (1%) of the aggregate Purchase Price that has actually been paid by such Holder in respect of its Registrable Securities on each of the following dates: (i) the day of a Filing Failure; (ii) the day of an Effectiveness Failure; (iii) the initial day of a Maintenance Failure; (iv) on every thirtieth day after the day of a Filing Failure and thereafter (pro rated for periods totaling less than thirty days) until such Filing Failure is cured; (v) on every thirtieth day after the day of an Effectiveness Failure and thereafter (pro rated for periods totaling less than thirty days) until such Effectiveness Failure is cured, subject to adjustment as provided herein; and (vi) on every thirtieth day after the initial day of a Maintenance Failure and thereafter (pro rated for periods totaling less than thirty days) until such Maintenance Failure is cured. In the event of a failure by the Company to cure an Effectiveness Failure on or before the thirtieth day after the date of the Effectiveness Deadline as set forth in clause (v) above, the Registration Delay Payment (as defined herein) for failure to cure such an Effectiveness Failure after such initial 30-day cure period shall be increased to 1.5% per 30-day period thereafter; provided, however, that the Company shall not be liable to a Holder for any such payments in excess of 10% of the aggregate Purchase Price that has actually been paid by such Holder in respect of its Registrable Securities. The payments to which a holder shall be entitled pursuant to this Section 2(b) are referred to herein as “Registration Delay Payments.” Registration Delay Payments shall be paid on the earlier of (I) the dates set forth above and (II) the third Business Day after the event or failure giving rise to the Registration Delay Payments is cured.

(c) In the event the number of shares available under a Registration Statement filed pursuant to Section 2(a) when declared effective or at any time thereafter is insufficient to cover all of the Registrable Securities required to be covered by such Registration Statement, the Company shall amend the applicable Registration Statement, or file a new Registration Statement (on the short form available therefor, if applicable), or both, so as to cover all of the Registrable Securities as of the Trading Day immediately preceding the date of the filing of such amendment or new Registration Statement, in each case, as soon as practicable, but in any event not later than the later of: (i) sixty (60) days after the date substantially all of the Registrable Securities previously included in the initial Registration Statement have been sold; or (ii) the date that is six (6) months after the Effective Date. The Company shall use its best efforts to cause such amendment and/or new Registration Statement to become effective as soon as practicable following the filing thereof.

(d) For the avoidance of doubt and notwithstanding anything contained herein to the contrary, no Registration Delay Payment is payable by the Company to any particular Holder if any such Filing Failure, Effectiveness Failure, or Maintenance Failure, as the case may be, in relation to such Holder’s Registrable Securities included in such Registration Statement is caused by the default of the obligations of the relevant Holder under this Agreement (including, without limitation, the obligations of the Holder as set forth in Section 3(a) below). In addition, notwithstanding anything contained herein to the contrary, in the event that the Company is

4

delinquent in filing the Registration Statement by a period of time such that the Effectiveness Deadline has passed and an Effectiveness Failure has occurred, so that a Registration Delay Payment is triggered for both the Filing Failure and the Effectiveness Failure concurrently, then the Company shall only be obligated to pay one Registration Delay Payment for the concurrent failures, for whichever failure results in a greater Registration Delay Payment.

3. Registration Procedures.

At such time as the Company is obligated to file a Registration Statement with the SEC pursuant to Section 2, the Company will use its best efforts to effect the registration of the Registrable Securities in accordance with the intended method of distribution thereof and, pursuant thereto, the Company shall have the following obligations:

(a) The Company shall not file a Registration Statement, any Prospectus, or any amendments or supplements thereto in which the “Selling Stockholder” section thereof differs from the disclosure received from a Holder in its Selling Shareholder Questionnaire (as amended and supplemented). Each Holder agrees to be named in the Registration Statement and to carry out the offer and sale of Registrable Securities held by such Holder in a conformance with the Plan of Distribution attached hereto as Annex A, as modified by the Company as necessary to conform to comments from the Commission. Each Holder agrees to furnish to the Company a completed Questionnaire in the form attached to this Agreement as Annex B (a “Selling Shareholder Questionnaire”) by the end of the eighth Trading Day following the date on which such Holder receives the Selling Shareholder Questionnaire and draft materials in accordance with this Section. The Company shall ensure that each Registration Statement (including any amendments or supplements thereto and prospectuses contained therein) shall not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein, or necessary to make the statements therein (in the case of prospectuses, in the light of the circumstances in which they were made) not misleading, except to the extent, but only to the extent, that (i) such untrue statements or omissions are based solely upon information regarding such Holder furnished in writing to the Company by such Holder, its directors, authorized officers or attorneys expressly for use therein, or to the extent that such information relates to such Holder or such Holder’s proposed method of distribution of Registrable Securities and was reviewed and expressly approved in writing by such Holder its directors, authorized officers or attorneys expressly for use in a Registration Statement, such Prospectus or such form of Prospectus or in any amendment or supplement thereto. Each Holder shall ensure that its Selling Shareholder Questionnaire furnished to the Company shall not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein, or necessary to make the statements therein not misleading.

(b) Not less than five Trading Days prior to the filing of each Registration Statement and not less than two Trading Days prior to the filing of any related amendment or supplement thereto, the Company shall permit the Holders to review and comment upon the Registration Statement and any amendments and supplements to all Registration Statements (except for Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and any similar or successor reports), and not file any Registration Statement or amendment or supplement thereto in a form to which the Holders or their legal counsel reasonably objects, provided that the Holders or their legal counsel shall provide the Company

5

with any comments within two (2) Trading Days of the receipt of the Registration Statement and shall provide the Company with any comments within one (1) Trading Day of the receipt of any related amendment or supplement thereto. The Company shall furnish to the Holder, without charge, (i) copies of any correspondence from the Commission or the staff of the Commission to the Company or its representatives relating to any Registration Statement, (ii) promptly after the same is prepared and filed with the Commission, one copy of any Registration Statement and any amendment(s) thereto, including financial statements and schedules, all documents incorporated therein by reference, if requested by a Holder and not otherwise available on the EDGAR system, and all exhibits and (iii) upon the effectiveness of any Registration Statement, one copy of the prospectus included in such Registration Statement and all amendments and supplements thereto.

(c) (i) Prepare and file with the Commission such amendments, including post-effective amendments, to a Registration Statement and the Prospectus used in connection therewith as may be necessary to keep a Registration Statement continuously effective as to the applicable Registrable Securities for the Effectiveness Period, except for periods based on events described in Section 3(d), (ii) cause the related Prospectus to be amended or supplemented by any required Prospectus supplement (subject to the terms of this Agreement), and as so supplemented or amended to be filed pursuant to Rule 424; (iii) respond promptly to any comments received from the Commission with respect to a Registration Statement or any amendment thereto; and (iv) comply in all material respects with the provisions of the Securities Act and the Exchange Act applicable to the Company with respect to the disposition of all Registrable Securities covered by a Registration Statement during the applicable period in accordance with the intended methods of disposition by the Holders thereof set forth in such Registration Statement as so amended or in such Prospectus as so supplemented.

(d) Notify the Holders of Registrable Securities to be sold (which notice shall, pursuant to clauses (ii) through (iv) hereof, be accompanied by an instruction to suspend the use of the Prospectus until the requisite changes have been made) as promptly as reasonably possible, and in any event within one (1) Trading Day after the occurrence of the event requiring notice herein, (i) with respect to a Registration Statement or any post-effective amendment, when the same has become effective; (ii) of the issuance by the Commission or any other federal or state governmental authority of any stop order suspending the effectiveness of a Registration Statement covering any or all of the Registrable Securities; (iii) of the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction; (iv) of the occurrence of any event or passage of time that makes the financial statements included in a Registration Statement ineligible for inclusion therein or any statement made in a Registration Statement or Prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires any revisions to a Registration Statement, Prospectus or other documents so that, in the case of a Registration Statement or the Prospectus, as the case may be, it will not contain any 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, in light of the circumstances under which they were made, not misleading; or (v) when the Commission notifies the Company whether there will be a review of such Registration Statement and whenever the Commission comments in writing on such Registration Statement (the Company shall provide true and complete copies thereof and all written responses thereto to

6

each of the Holders that pertain to the Holders as a Selling Stockholder or to the Plan of Distribution, but not information which the Company believes would constitute material and non-public information). Any and all of such information contemplated by subparagraphs (i) through (v) shall remain confidential to each Holder until such information otherwise becomes public, unless disclosure by a Holder is required by law.

(e) Use its best efforts to avoid the issuance of, or, if issued, obtain the withdrawal of (i) any order suspending the effectiveness of a Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction, at the earliest practicable moment.

(f) Furnish to each Holder whose Registrable Securities are included in any Registration Statement, without charge, if not otherwise available on the EDGAR system (i) promptly after the same is prepared and filed with the Commission, at least one copy of such Registration Statement and any amendment(s) thereto, including financial statements and schedules, all documents incorporated therein by reference, if requested by a Holder, all exhibits and each preliminary prospectus, (ii) upon the effectiveness of any Registration Statement, ten (10) copies of the prospectus included in such Registration Statement and all amendments and supplements thereto (or such other number of copies as such Holder may reasonably request) and (iii) such other documents, including copies of any preliminary or final prospectus, as such Holder may reasonably request from time to time in order to facilitate the disposition of the Registrable Securities owned by such Holder.

(g) Subject to the terms of this Agreement, the Company hereby consents to the use of each Prospectus and each amendment or supplement thereto, provided by the Company pursuant to subpart (f) above, by each of the selling Holders in connection with the offering and sale of the Registrable Securities covered by such Prospectus and any amendment or supplement thereto, except after the giving of any notice pursuant to Section 3(d).

(h) Prior to any resale of Registrable Securities by a Holder, register or qualify or cooperate with the selling Holders in connection with the registration or qualification (or exemption from the Registration or qualification) of such Registrable Securities for the resale by the Holder under the securities or Blue Sky laws of such jurisdictions within the United States as any Holder reasonably requests in writing, to keep each registration or qualification (or exemption therefrom) effective during the Effectiveness Period and to do any and all other acts or things reasonably necessary to enable the disposition in such jurisdictions of the Registrable Securities covered by each Registration Statement; provided, that the Company shall not be required to qualify generally to do business in any jurisdiction where it is not then so qualified, subject the Company to any material tax in any such jurisdiction where it is not then so subject or file a general consent to service of process in any such jurisdiction.

(i) Within two (2) Trading Days after a Registration Statement which covers Registrable Securities is ordered effective by the Commission, deliver, and shall cause legal counsel for the Company to deliver, to the transfer agent for such Registrable Securities (with copies to the Holders whose Registrable Securities are included in such Registration Statement) confirmation that such Registration Statement has been declared effective by the Commission. The Company shall cooperate with the Holders to facilitate the timely preparation and delivery

7

of certificates representing Registrable Securities to be delivered to a transferee pursuant to the Registration Statement, which certificates shall be free, to the extent permitted by the Securities Act, of all restrictive legends, and to enable such Registrable Securities to be in such denominations and registered in such names as any such Holders may reasonably request.

(j) Upon the occurrence of any event contemplated by this Section 3, as promptly as reasonably possible under the circumstances taking into account the Company’s good faith assessment of any adverse consequences to the Company and its stockholders of the premature disclosure of such event, prepare a supplement or amendment, including a post–effective amendment, to a Registration Statement or a supplement to the related Prospectus or any document incorporated or deemed to be incorporated therein by reference, and file any other required document so that, as thereafter delivered, neither a Registration Statement nor such Prospectus will contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. If the Company notifies the Holders in accordance with clauses (ii) through (iv) of Section 3(d) above to suspend the use of any Prospectus until the requisite changes to such Prospectus have been made, then the Company will use its best efforts to ensure that the use of the Prospectus may be resumed as promptly as is practicable. The Company shall be entitled to exercise its right under this Section 3(j) to suspend the availability of a Registration Statement and Prospectus, provided that each period (each, a “Grace Period”) shall not exceed fifteen (15) consecutive days and during any three hundred sixty five (365) day period such Grace Periods shall not exceed an aggregate of thirty (30) days and the first day of any Grace Period must be at least five (5) trading days after the last day of any prior Grace Period (each, an “Allowable Grace Period”). The Company shall notify the Holders in writing of the date on which any Grace Period ends. For the purpose of determining the length of a Grace Period above, the Grace Period shall begin on and include the date the Holders receive the notice referred to above and shall end on the date the Holders receive the notice referred to in the preceding sentence.

(k) Comply with all applicable rules and regulations of the Commission.

(l) Prior to the effectiveness of the Registration Statement and all other amendments and supplements to the Prospectus, the Company may require each selling Holder to furnish to the Company a certified statement as to (i) the number of shares of Common Stock beneficially owned by such Holder, (ii) the natural persons thereof that have voting and dispositive control over the shares of Common Stock, and (iii) any affiliation between the Holder and either the Company’s independent registered public accountants or any member of FINRA, the Financial Industry Regulatory Authority (formerly NASD).

(m) The Company shall use its best efforts either to cause all of the Registrable Securities covered by a Registration Statement to be listed on the primary securities exchange or stock market on which securities of the same class or series issued by the Company are then listed, if any, if the listing of such Registrable Securities is then permitted under the rules of such exchange or stock market.

(n) Neither the Company nor any Subsidiary or affiliate thereof shall identify any Holder as an underwriter in any public disclosure or filing with the SEC or stock exchange

8

or market and the fact that any Holder is deemed an underwriter by the SEC shall not relieve the Company of any obligations it has under this Agreement or any other Transaction Document (as defined in the Purchase Agreement).

(o) If requested by a Holder, the Company shall as soon as practicable (i) incorporate in a prospectus supplement or post-effective amendment such information as a Holder reasonably requests to be included therein relating to the sale and distribution of Registrable Securities, including, without limitation, information with respect to the number of Registrable Securities being offered or sold, the purchase price being paid therefor and any other terms of the offering of the Registrable Securities to be sold in such offering; (ii) make all required filings of such prospectus supplement or post-effective amendment after being notified of the matters to be incorporated in such prospectus supplement or post-effective amendment; and (iii) supplement or make amendments to any Registration Statement if reasonably requested by a Holder holding any Registrable Securities.

4. Registration Expenses. All fees and expenses incidental to the performance of or compliance with this Agreement by the Company shall be borne by the Company whether or not any Registrable Securities are sold pursuant to a Registration Statement. The fees and expenses referred to in the foregoing sentence shall include, without limitation, (i) all registration and filing fees (including, without limitation, fees and expenses (A) with respect to filings required to be made with any securities exchange or stock market on which the Common Stock is then listed for trading, and (B) in compliance with applicable state securities or Blue Sky laws reasonably agreed to by the Company in writing), (ii) printing expenses incurred by the Company (including, without limitation, expenses of printing certificates for Registrable Securities), (iii) messenger, telephone and delivery expenses incurred by the Company, (iv) fees and disbursements of counsel for the Company, (v) Securities Act liability insurance incurred by the Company, if the Company so desires such insurance, and (vi) fees and expenses of all other Persons retained by the Company in connection with the consummation of the transactions contemplated by this Agreement. In addition, the Company shall be responsible for all of its internal expenses incurred in connection with the consummation of the transactions contemplated by this Agreement (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expense of any annual audit and the fees and expenses incurred in connection with the listing of the Registrable Securities on any securities exchange as required hereunder. In no event shall the Company be responsible for any broker or similar commissions of any Holder or, except to the extent provided for in the Transaction Documents, any legal fees or other costs of the Holders. The Company shall also reimburse the Holders for the fees and disbursements of one legal counsel for all Holders in connection with the registrations, filings, and qualifications made pursuant to this Agreement, which amount shall be limited to $20,000 for each Registration Statement filed hereunder.

5. Indemnification.

(a) Indemnification by the Company. The Company shall, notwithstanding any termination of this Agreement, indemnify and hold harmless each Holder, the officers, directors, agents, investment advisors, members, partners, and employees of each of them, each Person who controls any such Holder (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers, directors, members, shareholders, partners, and

9

employees of each such controlling Person, to the fullest extent permitted by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including, without limitation, reasonable attorneys’ fees) and expenses (collectively, “Losses”), as incurred, arising out of or relating to (1) any untrue statement of a material fact contained in a Registration Statement, any Prospectus or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus or form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, (2) any violation by the Company of the Securities Act, Exchange Act or any state securities law, or any rule or regulation thereunder, in connection with the performance of its obligations under this Agreement, except to the extent, but only to the extent, that (i) such untrue statements or omissions are based solely upon information regarding such Holder furnished in writing to the Company by such Holder, its directors, authorized officers, or attorneys expressly for use therein, or to the extent that such information relates to such Holder or such Holder’s proposed method of distribution of Registrable Securities and was reviewed and expressly approved in writing by such Holder, its directors, authorized officers, or attorneys expressly for use in a Registration Statement, such Prospectus or such form of Prospectus or in any amendment or supplement thereto (it being understood that the Holder has approved Annex A hereto for this purpose), (ii) in the case of an occurrence of an event of the type specified in Section 3(d)(ii)-(iv), the use by such Holder of an outdated or defective Prospectus after the Company has notified such Holder in writing that the Prospectus is outdated or defective and prior to the receipt by such Holder of the Advice contemplated in Section 7(c), or (iii) any such untrue statement, omission or violation is directly related to and primarily the result of a material breach of this Agreement or violation of law by Holder; or (3) any material breach of this Agreement by the Company.

(b) Indemnification by Holders. Each Holder shall, severally and not jointly, indemnify and hold harmless the Company, its directors, officers, agents, attorneys and employees, each Person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, agents, attorneys or employees of such controlling Persons, to the fullest extent permitted by applicable law, from and against all Losses, as incurred, to the extent arising out of or based solely upon any untrue or alleged untrue statement of a material fact contained in any Registration Statement, any Prospectus, or any form of prospectus, or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading (i) to the extent, but only to the extent, that such untrue statement or omission is contained in any information so furnished in writing by such Holder, its directors, authorized officers, or attorneys to the Company specifically for inclusion in such Registration Statement or such Prospectus or (ii) to the extent that such information relates to such Holder’s proposed method of distribution of Registrable Securities and was reviewed and expressly approved in writing by such Holder, its directors, authorized officers, or attorneys expressly for use in a Registration Statement (it being understood that the Holder has approved Annex A hereto for this purpose), such Prospectus or such form of Prospectus or in any amendment or supplement thereto. In no event shall the liability of any selling Holder hereunder be greater in amount than the dollar amount of the net proceeds received by such Holder upon the sale of the Registrable Securities giving rise to such indemnification obligation.

10

(c) Conduct of Indemnification Proceedings. If any Proceeding shall be brought or asserted against any Person entitled to indemnity hereunder (an “Indemnified Party”), such Indemnified Party shall promptly notify the Person from whom indemnity is sought (the “Indemnifying Party”) in writing, and the Indemnifying Party shall have the right to assume the defense thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all fees and expenses incurred in connection with defense thereof; provided, that the failure of any Indemnified Party to give such notice shall not relieve the Indemnifying Party of its obligations or liabilities pursuant to this Agreement, except (and only) to the extent that such failure shall have prejudiced the Indemnifying Party.

An Indemnified Party shall have the right to employ separate counsel in any such Proceeding and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party or Parties unless: (1) the Indemnifying Party has agreed in writing to pay such fees and expenses; (2) the Indemnifying Party shall have failed promptly to assume the defense of such Proceeding and to employ counsel reasonably satisfactory to such Indemnified Party in any such Proceeding; or (3) the named parties to any such Proceeding (including any impleaded parties) include both such Indemnified Party and the Indemnifying Party, and a material conflict of interest is likely to exist if the same counsel were to represent such Indemnified Party and the Indemnifying Party, in which case, if such Indemnified Party notifies the Indemnifying Party in writing that it elects to employ separate counsel at the expense of the Indemnifying Party, the Indemnifying Party shall not have the right to assume the defense thereof and the reasonable fees and expenses of no more than one separate counsel shall be at the expense of the Indemnifying Party. The Indemnifying Party shall not be liable for any settlement of any such Proceeding effected without its written consent, which consent shall not be unreasonably withheld or delayed.

Subject to the terms of this Agreement, all reasonable fees and expenses of the Indemnified Party owing under this Section 5 (including reasonable fees and expenses to the extent incurred in connection with investigating or preparing to defend such Proceeding in a manner not inconsistent with this Section) shall be paid to the Indemnified Party.

(d) Contribution. If the indemnification under Section 5(a) or 5(b) is unavailable to an Indemnified Party or insufficient to hold an Indemnified Party harmless for any Losses, then each Indemnifying Party shall contribute to the amount paid or payable by such Indemnified Party, in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified Party in connection with the actions, statements or omissions that resulted in such Losses as well as any other relevant equitable considerations. The relative fault of such Indemnifying Party and Indemnified Party shall be determined by reference to, among other things, whether any action in question, including any untrue statement of a material fact or omission of a material fact, has been taken or made by, or relates to information supplied by, such Indemnifying Party or Indemnified Party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action, statement or omission. The amount paid or payable by a party as a result of any Losses shall be deemed to include, subject to the limitations set forth in this Agreement, any reasonable attorneys’ or other fees or expenses incurred by such party in connection with any Proceeding to the extent such party would have been indemnified for such fees or expenses if the indemnification provided for in this Section was available to such party in accordance with its terms.

11

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 5(d) were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this Section 5(d), no Holder shall be required to contribute, in the aggregate, any amount in excess of the amount by which the proceeds actually received by such Holder from the sale of the Registrable Securities subject to the Proceeding exceeds the amount of any damages that such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission, except in the case of fraud by such Holder.

The indemnity and contribution agreements contained in this Section are in addition to any liability that the Indemnifying Parties may have to the Indemnified Parties.

6. Reports Under the Exchange Act.

With a view to making available to the Holders the benefits of Rule 144 promulgated under the Securities Act or any other similar rule or regulation of the Commission that may at any time permit the Holders to sell securities of the Company to the public without registration (“Rule 144”), the Company agrees to:

(a) make and keep public information available, as those terms are understood and defined in Rule 144;

(b) file with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act so long as the Company remains subject to such requirements and the filing of such reports and other documents is required for the applicable provisions of Rule 144; and

(c) furnish to each Holder so long as such Holder owns Registrable Securities, promptly upon request, (i) a written statement by the Company, if true, that it has complied with the reporting requirements of Rule 144, the Securities Act and the Exchange Act, (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company, and (iii) such other information as may be reasonably requested to permit the Holders to sell such securities pursuant to Rule 144 without registration.

7. Miscellaneous.

(a) Other Registration Rights. Except for any registration statements filed or to be filed in respect of the holders of registration rights as set forth in Schedule 4.3 of the Disclosure Schedules, the Company agrees and covenants that it will not register the shares of any other holder of its securities prior to registering the Shares. The Company and its security holders (other than the Holders in such capacity pursuant hereto) designated by the Company may include securities of the Company in the Registration Statement in addition to the Registrable Securities; provided, however, Company agrees to limit the inclusion of, or otherwise exclude, such securities in the Registration Statement to the extent necessary in order to satisfy its obligations pursuant to Section 2 above or to the extent necessary to register of all Registrable Securities as promptly as possible.

12

(b) Compliance. Each Holder covenants and agrees that it will comply with the prospectus delivery requirements of the Securities Act as applicable or an exemption therefrom to it in connection with sales of Registrable Securities pursuant to a Registration Statement.

(c) Discontinued Disposition. Each Holder agrees by its acquisition of Registrable Securities that, upon receipt of a notice from the Company of the occurrence of any event of the kind described in Section 3(d), such Holder will forthwith discontinue disposition of such Registrable Securities under a Registration Statement until it is advised in writing (the “Advice”) by the Company that the use of the applicable Prospectus (as it may have been supplemented or amended) may be resumed. The Company will use its best efforts to ensure that the use of the Prospectus may be resumed as promptly as possible.

(d) Amendments and Waivers. No provision of this Agreement may be amended or waived except in a written instrument signed by the Company and the Holders holding not less than a majority of the Registrable Securities; provided, however, that if any amendment or waiver operates in a manner that treats any Holder differently from the other Holders, the consent of such Holder shall also be required for such amendment or waiver. No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of any party to exercise any right hereunder in any manner impair the exercise of any such right.

(e) Notices. Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be delivered as set forth in the Purchase Agreement.

(f) Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors and permitted assigns of each of the parties and shall inure to the benefit of each Holder. The Company may not assign its rights or obligations hereunder without the prior written consent of each Holder. The rights under this Agreement shall be automatically assignable by any Holder to any transferee of such Holder’s Registrable Securities if: (i) such Holder agrees in writing with the transferee or assignee to assign such rights and a copy of such agreement is furnished to the Company promptly after such assignment; (ii) the Company is, promptly after such transfer or assignment, furnished with written notice of (a) the name and address of such transferee or assignee; (b) the securities with respect to which such registration rights are being transferred or assigned; and (c) the Company is provided with a Selling Shareholder Questionnaire executed by such transferee; (iii) immediately following such transfer or assignment the further disposition of such securities by the transferee or assignee is restricted under the Securities Act and applicable state securities laws; (iv) at or before the time the Company receives the written notice contemplated by clause (ii) of this sentence the transferee or assignee agrees in writing with the Company to be bound by all of the provisions contained herein; and (v) such transfer shall have been made in accordance with the applicable requirements of the Purchase Agreement.

(g) No Inconsistent Agreements. Neither the Company nor any of its Subsidiaries has entered, as of the date hereof, nor shall the Company or any of its Subsidiaries,

13

on or after the date of this Agreement, enter into any agreement with respect to its securities, that would have the effect of impairing the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof.

(h) Execution and Counterparts. This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature page were an original thereof.

(i) Governing Law; Consent to Jurisdiction; Waiver of Jury Trial. This Agreement shall be governed by, and construed in accordance with, the internal laws of the State of New York without regard to the choice of law principles thereof. Each of the parties hereto irrevocably submits to the exclusive jurisdiction of the courts of the State of New York located in New York County and the United States District Court for the Southern District of New York for the purpose of any suit, action, proceeding or judgment relating to or arising out of this Agreement and the transactions contemplated hereby. Service of process in connection with any such suit, action or proceeding may be served on each party hereto anywhere in the world by the same methods as are specified for the giving of notices under this Agreement. Each of the parties hereto irrevocably consents to the jurisdiction of any such court in any such suit, action or proceeding and to the laying of venue in such court. Each party hereto irrevocably waives any objection to the laying of venue of any such suit, action or proceeding brought in such courts and irrevocably waives any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. EACH OF THE PARTIES HERETO WAIVES ANY RIGHT TO REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS AGREEMENT AND REPRESENTS THAT COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS WAIVER.

(j) Cumulative Remedies. The remedies provided herein are cumulative and not exclusive of any other remedies provided by law.

(k) Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their commercially reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable.

14

(l) Headings. The headings in this Agreement are for convenience only, do not constitute a part of this Agreement, and shall not be deemed to limit or affect any of the provisions hereof.

(m) Independent Nature of Purchasers’ Obligations and Rights. The obligations of each Purchaser under this Agreement are several and not joint with the obligations of each other Purchaser, and no Purchaser shall be responsible in any way for the performance of the obligations of any other Purchaser under this Agreement. Nothing contained herein or in any Transaction Document, and no action taken by any Purchaser pursuant thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by this Agreement or any other Transaction Document. Each Purchaser acknowledges that no other Purchaser will be acting as agent of such Purchaser in enforcing its rights under this Agreement. Each Purchaser shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of this Agreement, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose.

ANNEX A

Plan of Distribution

The selling stockholders may, from time to time, sell any or all of their shares of common stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These sales may be at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale, or at negotiated prices. The selling stockholders may use any one or more of the following methods when selling shares:

The selling stockholders may also sell shares under Rule 144 under the Securities Act, if available, rather than under this prospectus.

The selling stockholders may also engage in puts and calls and other transactions in our securities or derivatives of our securities and may sell or deliver shares in connection with these trades.

Broker-dealers engaged by the selling stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling stockholders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated. The selling stockholders do not expect these commissions and discounts to exceed what is customary in the types of transactions involved. Any profits on the resale of shares of common stock by a broker-dealer acting as principal might be deemed to be underwriting discounts or commissions under the Securities Act. Discounts, concessions, commissions and similar selling expenses, if any, attributable to the sale of shares will be borne by a selling stockholder. The selling stockholders may agree to indemnify any agent, dealer or broker-dealer that participates in transactions involving sales of the shares if

18

liabilities are imposed on that person under the Securities Act. In connection with sales of the shares of common stock or otherwise, the selling stockholders may enter into hedging transactions with broker-dealers, which may in turn engage in short sales of the shares of common stock in the course of hedging in positions they assume. The selling stockholders may also sell shares of common stock short and deliver shares of common stock covered by this prospectus to close out short positions and to return borrowed shares in connection with such short sales. The selling stockholders may also loan or pledge shares of common stock to broker-dealers that in turn may sell such shares.

The selling stockholders may from time to time pledge or grant a security interest in some or all of the shares of common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock from time to time under this prospectus after we have filed a supplement to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act of 1933 amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus.

The selling stockholders also may transfer the shares of common stock in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus and may sell the shares of common stock from time to time under this prospectus after we have filed a supplement to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act of 1933 amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus.

The selling stockholders and any broker-dealers or agents that are involved in selling the shares of common stock may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the shares of common stock purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act.

We are required to pay all fees and expenses incident to the registration of the shares of common stock. We have agreed to indemnify the selling stockholders against certain claims, damages and liabilities, including liabilities under the Securities Act.

The selling stockholders have advised us that they have not entered into any agreements, understandings or arrangements with any underwriters or broker-dealers regarding the sale of their shares of common stock, nor is there an underwriter or coordinating broker acting in connection with a proposed sale of shares of common stock by any selling stockholder. If we are notified by any selling stockholder that any material arrangement has been entered into with a broker-dealer for the sale of shares of common stock, if required, we will file a supplement to this prospectus. If the selling stockholders use this prospectus for any sale of the shares of common stock, they will be subject to the prospectus delivery requirements of the Securities Act.

Under the securities laws of some states, the shares of common stock may be sold in such states only through registered or licensed brokers or dealers. In addition, in some states the shares of common stock may not be sold unless such shares have been registered or qualified for sale in such state or an exemption from registration or qualification is available and is complied with.

19

There can be no assurance that any selling stockholder will sell any or all of the shares of common stock registered pursuant to the shelf registration statement, of which this prospectus forms a part.

The selling stockholders and any other person participating in such distribution will be subject to applicable provisions of the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder, including, without limitation, Regulation M of the Exchange Act, which may limit the timing of purchases and sales of any of the shares of common stock by the selling stockholders and any other participating person. Regulation M may also restrict the ability of any person engaged in the distribution of the shares of common stock to engage in market-making activities with respect to the shares of common stock. All of the foregoing may affect the marketability of the shares of common stock and the ability of any person or entity to engage in market-making activities with respect to the shares of common stock.

Once sold under the shelf registration statement, of which this prospectus forms a part, the shares of common stock will be freely tradable in the hands of persons other than our affiliates.
