REGISTRATION RIGHTS AGREEMENT

Exhibit 4.1

THIS REGISTRATION RIGHTS AGREEMENT (this “Agreement”) is made as of April 30, 2010, by and among Six Flags Entertainment Corporation, a Delaware corporation formerly known as Six Flags, Inc. (the “Company”), and each of the other Persons signatory hereto or that executes and delivers a joinder agreement pursuant to Section 10 hereof. Capitalized terms used but not otherwise defined herein are defined in Section 11 hereof.

NOW, THEREFORE, in consideration of the mutual covenants and agreements contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound, agree as follows:

1. Demand and Shelf Registrations.

(a) Demand Registrations. At any time that the Company has not effected or is not diligently pursuing a Shelf Registration pursuant to Section 1(b), after the date that is one hundred and twenty (120) days after the Effective Date, Holder(s) of at least twenty percent (20%) of the Registrable Securities then issued and outstanding (the “Initiating Holders”) may request registration under the Securities Act of all or any portion of their Registrable Securities in an Underwritten Offering (an “Underwritten Demand Offering”) on (i) Form S-1 or any similar long-form registration statement (a “Long-Form Registration”), or, if available, (ii) Form S-3 or any similar short-form registration statement (a “Short-Form Registration”) (any registration under this Section 1(a), a “Demand Registration”).

(b) Shelf Registration. The Company shall, as soon as reasonably practicable, but in any event within thirty (30) days following the Effective Date, file a registration statement on any permitted form that qualifies, and is available for, the sale of Registrable Securities, with the Securities and Exchange Commission in accordance with and pursuant to Rule 415 promulgated under the Securities Act (or any successor rule then in effect) (the “Shelf Registration”), and shall thereafter, subject to Section 1(c), use its reasonable best efforts to cause such Registration Statement to be declared effective as promptly as practicable. If any Registrable Securities remain issued and outstanding after three (3) years following the initial effective date of such Shelf Registration (the “Initial Shelf Effective Date”), the Company shall, prior to the expiration of such Shelf Registration, file a new Shelf Registration covering such Registrable Securities and shall thereafter use its best efforts to cause to be declared effective as promptly as practical, such new Shelf Registration. The Company shall use its reasonable best efforts to convert any Shelf Registration effected as a Long-Form Registration (a “Long-Form Shelf”) to a Short-Form Registration (a “Short-Form Shelf,” and together with any Long-Form Shelf, the “Shelf”) as promptly as reasonably practicable after the Company is eligible to use a Short-Form Registration.

(c) Information from Holders. In order to be named as a selling securityholder in the Shelf Registration as of the Initial Shelf Effective Date, each Holder must no later than five (5) Business Days prior to the Initial Shelf Effective Date, which will be at least twenty (20) days following notice by the Company of the expected Initial Shelf Effective Date, furnish to the Company in writing such information in writing as may be reasonably requested by the

Company for the purpose of including such Holder’s Registrable Securities in the Shelf Registration (the “Selling Holder Information”). The Company shall include in the Shelf Registration Selling Holder Information received by the Company at least five (5) Business Days prior to the Initial Shelf Effective Date, to the extent necessary and in a manner so that upon Initial Shelf Effective Date the Holder shall be named as a selling securityholder and be permitted to deliver (or be deemed to deliver) a prospectus relating to the Shelf Registration to purchasers of the Registrable Securities in accordance with applicable law.

From and after the Initial Shelf Effective Date (including with respect to a Shelf that is not the initial Shelf Registration), upon receipt of Selling Holder Information (including any updated Selling Holder Information) that the Company may reasonably request in writing (including any amendments to any prior Selling Holder Information), if any, but in any event within ten (10) Business Days (in the case of a supplement) or within thirty (30) calendar days (in the case of an amendment), as applicable, after the Company receives such requested Selling Holder Information, if any, the Company shall use its reasonable best efforts to file any amendments or supplements, as applicable, to the Shelf Registration or a prospectus relating to the Shelf Registration or the documents incorporated by reference therein necessary for such Holder to be named as a selling securityholder and permit such Holder to deliver (or be deemed to deliver) a prospectus relating to the Shelf Registration to purchasers of the Registrable Securities (subject to the Company’s rights during any Delay Period or Suspension Period); provided, however, that the Company shall not be required to file more than one (1) such amendment. Holders that do not deliver Selling Holder Information as provided for in this Section 1(c) shall not be named as selling securityholders in the prospectus relating to the Shelf Registration until such Holder delivers such information. If the Company shall file a post-effective amendment to the Shelf Registration, it shall use reasonable best efforts to cause such post-effective amendment to be declared effective under the Securities Act as promptly as is reasonably practicable and notify such Holder as promptly as is reasonably practicable after the effectiveness under the Securities Act of any post-effective amendment. If such Selling Holder Information is delivered during a Delay Period or Suspension Period, the Company shall so inform the Holder delivering such Selling Holder Information and shall take the actions set forth in this Section 1(c) upon expiration of the Delay Period or Suspension Period, as applicable, as though such Holder’s Selling Holder Information had been delivered on the expiration date of such Delay Period or Suspension Period.

(d) Demand Notices and Requests for Underwritten Shelf Takedowns. One or more Holders may request (i) pursuant and subject to Section 1(a) and the other terms and conditions hereof, a Demand Registration, or (ii) pursuant and subject to Section 1(b) and the other terms and conditions hereof, to sell all or any portion of their Registrable Securities in an Underwritten Offering that is registered pursuant to the Shelf (an “Underwritten Shelf Takedown”). Each such request shall be made by giving written notice (an “Underwritten Offering Notice”) to the Company. Each Underwritten Offering Notice shall specify the approximate number of Registrable Securities requested to be registered, in the case of a Demand Registration, or sold, in the case of an Underwritten Shelf Takedown, and the anticipated per share price range for such offering (net of underwriting discounts or commissions). Within ten (10) days after receipt of any Underwritten Offering Notice, the Company shall give written notice of such requested registration or requested Underwritten Shelf Takedown, as applicable, to all other Holders of Registrable Securities and, subject to the provisions of Section 1(g) below, shall include in such

Demand Registration or Underwritten Shelf Takedown, as applicable, all Registrable Securities with respect to which the Company has received written requests for inclusion therein within fifteen (15) days after the receipt of the Company’s notice. Following the delivery of an Underwritten Offering Notice in connection with a Demand Registration, the Company shall use its reasonable best efforts to make such filing within forty-five (45) days of receipt of such Underwritten Offering Notice, and use its reasonable best efforts to cause such registration statement to become effective within one hundred and twenty (120) days after receipt of an Underwritten Offering Notice.

(e) Registrations; Takedowns.

(i) A registration shall not count as one of the permitted Demand Registrations until it has become effective, and any Demand Registration shall not count as a Demand Registration unless the Initiating Holder(s) is able to register and sell at least eighty percent (80%) of the Registrable Securities requested to be registered by such Initiating Holder(s) in such Demand Registration; provided that the Company shall in any event pay all Registration Expenses in connection with any registration initiated as a Demand Registration whether or not it has become effective and whether or not such registration has counted as one of the permitted Demand Registrations; provided further that a Demand Registration which is withdrawn at the sole request of the Initiating Holder(s) who demanded such Demand Registration will count as a Demand Registration unless the Company is reimbursed by such Initiating Holder(s) for all reasonable out-of-pocket expenses incurred by the Company in connection with such registration.

(ii) An underwritten sale of Registrable Securities shall not count as one of the permitted Underwritten Shelf Takedowns unless the Holder(s) requesting any such Underwritten Shelf Takedown is able sell at least eighty percent (80%) of the Registrable Securities requested to be sold in such Underwritten Shelf Takedown; provided that an Underwritten Shelf Takedown which is withdrawn at the sole request of such Holder(s) will count as an Underwritten Shelf Takedown unless the Company is reimbursed by such Holder(s) for all reasonable out-of-pocket expenses incurred by the Company in connection with any such Underwritten Shelf Takedown.

(f) Short-Form Registrations. Demand Registrations shall be Short-Form Registrations whenever the Company is permitted to use any applicable short form.

(g) Priority on Demand Registrations and Underwritten Shelf Takedowns. Subject to Section 1(k), the Company shall not include in any Demand Registration or Underwritten Shelf Takedown any securities which are not Registrable Securities without the prior written consent of the Holder(s) of a majority of the Registrable Securities included in such registration. If any managing underwriter(s) advises the Company in writing that in its opinion the number of Registrable Securities and, if permitted hereunder, other securities requested to be included in an Underwritten Demand Offering or Underwritten Shelf Takedown exceeds the number of Registrable Securities and other securities, if any, which can be sold in an orderly manner in such offering within a price range acceptable to the Holder(s) of a majority of the Registrable Securities requesting such Demand Registration or requesting to be included in the Underwritten Shelf Takedown, as applicable, the Company shall include in such Demand Registration or

Underwritten Shelf Takedown the number which can be so sold in the following order of priority: first, the Registrable Securities requested to be included in such registration, which in the opinion of such underwriter(s) can be sold in an orderly manner within the price range of such offering, pro rata among the respective Holder(s) of such Registrable Securities on the basis of the number of shares of Common Stock owned by each such Holder(s), second, the securities to be sold for the account of the Company, and third, any other securities requested to be included in such registration to the extent permitted hereunder.

(h) Effectiveness Period. The Company shall use commercially reasonable efforts to keep each Registration Statement filed pursuant to this Section 1 continuously effective and usable for the resale of the Registrable Securities covered thereby (i) in the case of a registration that is not a Shelf Registration, for a period of one hundred twenty (120) days from the date on which the SEC declares such Registration Statement effective and (ii) in the case of a Shelf Registration, for a period of three (3) years from the date on which the SEC declares such Registration Statement effective; provided, however, that the time period for which the Company is required to maintain the effectiveness of any Registration Statement relating to a Demand Registration shall be extended by the aggregate number of days of all applicable Delay Periods and Suspension Periods occurring with respect to such registration, and such period and any extension thereof is hereinafter referred to as the “Effectiveness Period.” Notwithstanding the foregoing, the Company shall have no obligation to keep a Registration Statement effective after the date all securities covered by such Registration Statement have been sold by the Holder and the Effectiveness Period shall end on such date.

(i) Restrictions on Demand Registrations and Underwritten Offerings. Notwithstanding anything contained herein to the contrary, the Company shall not be obligated to:

(i) effect in the aggregate, more than five (5) Underwritten Offerings (whether by Short-Form Registration, Long-Form Registration or Underwritten Shelf Takedown);

(ii) effect in the aggregate, more than five (5) Long-Form Demand Registrations;

(iii) file a registration statement for a Demand Registration within one-hundred eighty (180) days after the effective date of a previous Demand Registration;

(iv) effect an Underwritten Offering prior to August 31, 2010 unless (x) the Company’s independent registered public accounting firm agrees to render and does render to the Company and the underwriters for such offering a standard and customary comfort letter in accordance with Auditing Standard AU Section 634 — “Letters for Underwriters and Certain Other Requesting Parties” of the Public Companies Accounting Oversight Board, and (y) such Underwritten Offering is approved be each member of an audit committee of the Company that has at least two members and that all members of such audit committee meet the audit committee independence requirements of the New York Stock Exchange, Inc.

(v) effect an Underwritten Offering within one-hundred eighty (180) days after the later of the closing of (x) an Underwritten Offering pursuant to Section 1 hereof, or (y) a Piggyback Registration in which Holders were able to sell at least 80% of the Registrable Securities requested to be included in such Piggyback Registration; or

(vi) effect a Demand Registration or an Underwritten Shelf Takedown unless the Fair Value of the amount of Registrable Securities to be registered and/or sold by the Holders pursuant to such Demand Registration or Underwritten Shelf Takedown, as applicable, is in excess of $100 million.

(j) Selection of Underwriters. The Holder(s) of a majority of the Registrable Securities included in an Underwritten Demand Offering or an Underwritten Shelf Takedown, as applicable, shall have the right to select the investment banker(s) and manager(s), subject to the Company’s approval (such approval not to be unreasonably withheld, conditioned or delayed).

(k) Other Registrations. The Company shall not grant to any Person the right (other than as set forth herein and except to employees and directors of the Company with respect to registrations on Form S-8 and with respect to registrations on Form S-4 (or any successor forms thereto)), to request the Company to register any securities of the Company, except such rights as are (i) not more favorable than or inconsistent with the rights granted to the Holders, and (ii) that do not adversely affect the priorities of the Holders set forth herein.

(l) Limitation. Notwithstanding the foregoing, the Company shall not be obligated to effect, or take action to effect, any Demand Registration or Underwritten Shelf Takedown during the period in which the Board of Directors of the Company determines that in the Board’s reasonable judgment and in good faith that the registration and distribution of the Registrable Securities covered or to be covered by such Demand Registration or Underwritten Shelf Takedown, as applicable, would materially interfere with any pending material financing, acquisition or corporate reorganization or other material corporate development involving the Company or any of its subsidiaries or would require premature disclosure thereof, and such disclosure would be materially adverse to the Company, and the Company may, at its option, direct that such request be delayed for a reasonable period of time (a “Delay Period”) and the Company shall notify the Holder(s) requesting such Demand Registration or Underwritten Shelf Takedown, as applicable, to such effect; provided, however, that (i) the aggregate number of days included in all Delay Periods during any consecutive twelve (12) months shall not exceed the aggregate of one-hundred twenty (120) days and (ii) a period of at least thirty (30) days shall elapse between the termination of any Delay Period and the commencement of the immediately succeeding Delay Period.

Furthermore, in the event that the Board of Directors of the Company determines that in the Board’s reasonable judgment and in good faith it is advisable to suspend for a period of time (a “Suspension Period”) the use of a prospectus included in a Registration Statement because the use of such prospectus would materially interfere with any pending material financing, acquisition or corporate reorganization or other material corporate development involving the Company or any of its subsidiaries or would require premature disclosure thereof, and such disclosure would be materially adverse to the Company, the Company shall, in connection with a prospectus relating to an offering that is not underwritten, notify the Holders whose securities are

included in such prospectus and, if the prospectus relates to an underwritten offering, notify the managing underwriter(s), to such effect, and, upon receipt of such notice, such Holders or managing underwriter(s), as applicable, shall immediately discontinue any sales of Registrable Securities pursuant to such Registration Statement until:

(i) such Holders or managing underwriter(s), as applicable, have been advised that the supplemented or amended prospectus has been filed with the SEC on XXXXX and, if required by terms of an underwriting agreement relating to Registrable Securities covered by such Registration Statement, the managing underwriter(s) has received copies of a supplemented or amended prospectus, or

(ii) such Holders and managing underwriter(s), as applicable, are advised in writing by the Company that the then current prospectus may be used and, if required by terms of an underwriting agreement relating to Registrable Securities covered by such Registration Statement, the managing underwriter has received copies of any additional or supplemental filings that are incorporated or deemed incorporated by reference in such prospectus.

Notwithstanding anything to the contrary contained herein, the Company shall not exercise its rights under the preceding sentence to suspend sales pursuant to a Suspension Period for a period in excess of forty-five (45) days consecutively or one-hundred twenty (120) days in any twelve (12) month period. In the event of any Delay Period or Suspension Period, the Holder(s) of Registrable Securities initially requesting an Underwritten Demand Offering or Underwritten Shelf Takedown that is delayed or suspended by operation of this Section 1(l) shall have the right (i) in the case of a delay of the filing or effectiveness of a registration statement in connection with a Demand Registration, upon the affirmative approval of the Holders of not less than a majority of the Registrable Securities initially requesting such Demand Registration, to withdraw such request by giving written notice to the Company within twenty (20) days after receipt of such notice of delay or, if earlier, the termination of such Delay Period, and, if such request is withdrawn, such Demand Registration shall not count as one of the permitted Demand Registrations hereunder, and the Company shall pay all Registration Expenses in connection with such registration, (ii) in the case of a suspension of a prospectus (including the suspension of filing any prospectus supplement) in connection with an Underwritten Shelf Takedown, upon the affirmative approval of the Holders of not less than a majority of the Registrable Securities requesting to be included in such Underwritten Shelf Takedown, to withdraw such request by giving written notice to the Company within twenty (20) days after receipt of such notice of suspension or, if earlier, the termination of such Suspension Period, and, if such request is withdrawn, such Underwritten Shelf Takedown shall not count as one of the permitted Underwritten Shelf Takedowns hereunder and (iii) in the case of a suspension of sales in connection with a Demand Registration, to receive an extension of the registration period equal to the number of days of the Suspension Period. The Company shall not be entitled to initiate or continue a Delay Period or a Suspension Period unless it shall (A) concurrently prohibit sales by all other security holders under registration statements covering securities held by such other security holders and (B) in accordance with the Company’s policies from time to time in effect, if applicable, forbid purchases and sales in the open market by executive officers of the Company. The Company shall not be entitled to suspend sales pursuant to a Suspension Period

unless it shall have given notice of the Suspension Period before the commencement of marketing activities in connection with any Underwritten Offering.

2. Piggyback Offerings.

(a) Right to Piggyback. Whenever the Company proposes to register any of its equity securities under the Securities Act (other than pursuant to a Demand Registration and other than pursuant to a registration statement on Form X-0, Xxxx X-0 or any successor forms thereto), or otherwise proposes to offer any of its equity securities under the Securities Act in an Underwritten Offering either for its own account or for the account of one or more securityholders and the Company is eligible to use a registration form for such offering that may be used for the registration of Registrable Securities (a “Piggyback Offering”), the Company shall give prompt written notice to all Holders of Registrable Securities of its intention to effect such a registration (which notice shall be given not less than fifteen (15) days prior to the expected filing date of the Company’s registration statement; provided, however, that in the case of an Underwritten Offering under a Shelf Registration, such notice shall be given not less than five (5) Business Days prior to the date of commencement of marketing efforts for such offering) and shall, subject to the provisions of Section 2(c) below, include in such Piggyback Offering all Registrable Securities with respect to which the Company has received written requests for inclusion therein within ten (10) days after the receipt of the Company’s notice. Notwithstanding anything to the contrary contained herein, the Company may determine not to proceed with a registration which is the subject of such notice. A Piggyback Offering shall not be considered a Demand Registration for purposes of this Agreement and the rights to Piggyback Offerings may be exercised an unlimited number of occasions.

(b) Piggyback Expenses. The Registration Expenses of the Holders of Registrable Securities shall be paid by the Company in all Piggyback Offerings.

(i) If a Piggyback Offering is an Underwritten Offering on behalf of the Company, and the managing underwriter(s) advises the Company in writing that in its opinion the number of securities requested to be included in such registration exceeds the number which can be sold in an orderly manner in such offering within a price range acceptable to the Company, the Company shall include in such registration the number which can be so sold in the following order of priority: first, the securities to be sold for the account of the Company, second, the Registrable Securities requested to be included in such registration (pro rata among the Holder(s) of such Registrable Securities on the basis of the number of shares of Common Stock owned by each such Holder), and third, any other securities requested to be included in such registration.

(ii) If a Piggyback Offering is an Underwritten Offering on behalf of holders of the Company’s equity securities who are not Holders of Registrable Securities (“Other Holders”), and the managing underwriter(s) advises the Company in writing that in its opinion the number of equity securities requested to be included in such Piggyback Offering exceeds the number which can be sold in an orderly manner in such offering within a price range acceptable to the Other Holders, the Company shall include in such

registration the number which can be so sold in the following order of priority: first, the securities requested to be included therein by the Other Holders requesting such registration, second, the Registrable Securities requested to be included in such registration (pro rata among the Holder(s) of such Registrable Securities on the basis of the number of shares of Common Stock owned by each such Holder) and third, other securities requested to be included in such registration.

(iii) If, as a result of the proration provisions of this Section 2(c), any Holder shall not be entitled to include all Registrable Securities in a Piggyback Offering that such Holder has requested be included, such Holder may elect to withdraw its request to include Registrable Securities in such Piggyback Offering or may reduce the number requested to be included; provided, however, that (A) such request must be made in writing prior to commencement of marketing activities in connection with such Piggyback Offering and (B) such withdrawal shall be irrevocable and, after making such withdrawal, such Holder shall no longer have any right to include Registrable Securities in the Piggyback Offering as to which such withdrawal was made.

(d) Selection of Underwriters. If any Piggyback Offering is an Underwritten Offering, the Company will have the right to select the investment banker(s) and manager(s) for the offering.

3. Holdback Agreements.

(a) Holders of Registrable Securities. If requested by the lead managing underwriter, each Holder who “beneficially owns” (as such term is defined under and determined pursuant to Rule 13d-3 promulgated under the Exchange Act) five percent (5.0%) or more of the issued and outstanding Common Stock of the Company and each Holder including Registrable Securities in any Underwritten Demand Offering, Underwritten Shelf Takedown or Piggyback Offering shall not effect any public sale or distribution (including sales pursuant to Rule 144) of equity securities of the Company, or any securities convertible into or exchangeable or exercisable for such securities, during (i) with respect to any Underwritten Demand Offering, Underwritten Shelf Takedown or Piggyback Offering in which Registrable Securities are included, the seven (7) days prior to and the ninety (90)-day period beginning on the effective date of such registration, and (ii) upon notice from the Company of the commencement of a distribution in connection with any Underwritten Offering (including, but not limited to, any distribution in connection with any Shelf Registration) by or on behalf of the Company, the seven (7) days prior to and the ninety (90)-day period beginning on the date of commencement of such distribution (in the case of (i) and (ii), the “Lock-Up Period”), in each case except as part of such Underwritten Offering, and in each case unless the underwriters managing such Underwritten Offering otherwise agree; provided, however, that if any other Holder of Registrable Securities of the Company shall be subject to a shorter period or receives more advantageous terms relating to the Lock-Up Period, then the Lock-Up Period shall be such shorter period and also on such more advantageous terms and notwithstanding the foregoing, the Holders shall not be subject to the provisions hereof unless all of the Company’s directors and officers have signed lock-up agreements with the managing underwriters. The restrictions set forth in this Section 3(a) shall not be applicable to Transfers by Holders to Affiliates who agree to be bound by the provisions hereof, Transfers related to securities owned by Holders as a result of open market purchases

made following the closing of the applicable offerings, and other Transfers to which the underwriters managing such Underwritten Offering agree; provided, however, that nothing herein shall prevent a Holder that is a partnership or corporation from making a distribution of Registrable Securities to the partners or shareholders thereof that is otherwise in compliance with applicable securities laws, so long as such distributees agree to be bound by the terms hereof. The provisions of this Section 3(a) will no longer apply to a Holder once such Holder ceases to hold Registrable Securities.

(b) The Company. If requested by the lead managing underwriter, the Company (i) shall not effect any public sale or distribution of its equity securities, or any securities convertible into or exchangeable or exercisable for such securities (except pursuant to registrations on Form X-0, Xxxx X-0 or any successor forms thereto), with respect to any Underwritten Demand Offering, Underwritten Shelf Takedown or any Piggyback Offering that is an Underwritten Offering in which Registrable Securities are included, during the seven (7) days prior to and the ninety (90)-day period beginning on the pricing of such Underwritten Offering, and (ii) shall, to the extent permitted by Regulation FD of the Exchange Act, use its reasonable best efforts to cause each Person who “beneficially owns” (as such term is defined under and determined pursuant to Rule 13d-3 promulgated under the Exchange Act) five percent (5.0%) or more of the issued and outstanding Common Stock, or any securities convertible into or exchangeable or exercisable for Common Stock, purchased from the Company at any time after the date of this Agreement (other than in a registered public offering or pursuant to Rule 144) to agree not to effect any public sale or distribution (including sales pursuant to Rule 144) of any such securities during such period, in each case except as part of such Underwritten Offering, and in each case unless the underwriters managing the Underwritten Offering otherwise agree.

4. Registration Procedures. Whenever any Holder(s) of Registrable Securities has requested that any Registrable Securities be registered pursuant to this Agreement, the Company shall use its reasonable best efforts to effect the registration and the sale of such Registrable Securities in accordance with the intended method of disposition thereof, and pursuant thereto the Company shall as promptly as practicable:

(a) prepare and file with the Securities and Exchange Commission a registration statement with respect to such Registrable Securities in accordance with the provisions hereof, provided that before filing a registration statement or prospectus or any amendments or supplements thereto, the Company shall furnish to one counsel selected by the Holders of a majority of the Registrable Securities covered by such registration statement (“Counsel to the Holders”) copies of all such documents proposed to be filed, which documents shall be subject to the prompt review and comment of such Counsel to the Holders;

(b) notify each Holder of Registrable Securities of the effectiveness of each registration statement filed pursuant hereto and prepare and file with the Securities and Exchange Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective during the Effectiveness Period and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement during such period in accordance with the intended methods of disposition set forth in such registration statement;

(c) furnish to each seller of Registrable Securities, at such seller’s request, a copy of such registration statement, each amendment and supplement thereto, and the prospectus included in such registration statement (including each preliminary prospectus); provided, however, that the Company shall have no such obligation to furnish copies of a final prospectus if the conditions of Rule 172(c) under the Securities Act are satisfied by the Company;

and filing fees, fees and expenses of compliance with securities or blue sky laws, printing expenses, messenger and delivery expenses, fees and disbursements of custodians, and fees and disbursements of counsel for the Company and of all independent certified public accountants, underwriters (excluding discounts and commissions) and other Persons retained by the Company (all such expenses being herein called “Registration Expenses”), shall be borne by the Company. For the avoidance of doubt, the Company shall, in any event, pay its internal expenses (including all salaries and expenses of its officers and employees performing legal or accounting duties), the expense of any annual audit or quarterly review, the expense of any liability insurance and the expenses and fees for listing the securities to be registered on each securities exchange on which similar securities issued by the Company may then be listed.

(b) Reimbursement of Counsel. In connection with each Demand Registration, each Underwritten Shelf Takedown and each Piggyback Offering, the Company shall reimburse the Holders of Registrable Securities included in such registration for the reasonable fees and disbursements of Counsel to the Holders.

(c) Payment of Certain Expenses by Holders of Registrable Securities. Underwriting discounts and commissions and transfer taxes relating to the Registrable Securities included in any registration hereunder, and all fees and expenses of counsel for any Holders of Registrable Securities (other than fees and expenses to be reimbursed by the Company as set forth in Section 5(b) above) shall be borne and paid by all sellers of securities included in such registration in proportion to the aggregate selling price of the securities to be so registered.

6. Indemnification; Contribution.

(a) The Company agrees to indemnify, to the extent permitted by applicable law, each Holder of Registrable Securities, its officers, directors, employees, agents and Affiliates and each Person that controls such Holder (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and expenses (including attorneys’ fees and expenses, and expenses of investigation), arising out of or resulting from any untrue or alleged untrue statement of material fact contained in any registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto, any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, or violation or alleged violation by the Company of the Securities Act, the Exchange Act, any applicable state securities law (or any rule or regulation promulgated under any applicable state securities law), except insofar as the same are contained in any information furnished in writing to the Company by such Holder expressly for use therein or 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. In connection with an Underwritten Offering, the Company shall indemnify the underwriters, their officers and directors and each Person who controls such underwriters (within the meaning of the Securities Act) to the same extent as provided above with respect to the indemnification of the Holders of Registrable Securities.

(b) To the extent permitted by applicable law, each Holder shall indemnify the Company, its directors, officers, employees, agents and Affiliates and each Person that controls the Company (within the meaning of the Securities Act) against any losses, claims, damages,

liabilities and expenses (including attorneys’ fees and expenses, and expenses of investigation) arising out of or resulting from any untrue or alleged untrue statement of material fact contained in the registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by such Holder; provided that the obligation to indemnify shall be individual, not joint and several, for each Holder and shall be limited to the net amount of proceeds received by such Holder from the sale of Registrable Securities pursuant to such registration statement.

(c) Any Person entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any Person’s right to indemnification hereunder to the extent such failure has not materially prejudiced the indemnifying party) and (ii) permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s rights in the prior sentence, the indemnified party shall have the right to employ its own counsel (and one local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would in the reasonable judgment of the indemnified party present such counsel with a conflict of interest; (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and, based on advice of counsel to the indemnified party, the indemnified party shall have legal defenses available to it and/or other indemnified parties that are inconsistent with or in addition to those available to the indemnifying party; (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after written notice of the institution of such action has been delivered to the indemnifying party; or (iv) the indemnifying party shall have requested the indemnified party to employ separate counsel at the expense of the indemnifying party. No indemnifying party shall, in connection with any one action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general circumstances or allegations, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for all indemnified parties. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld). No indemnifying party, in the defense of any such claim or litigation, shall, except with the consent of each indemnified party, consent to entry of any judgment or enter into any settlement or compromise that does not include as an unconditional term thereof the giving by the claimant or plaintiff therein, to such indemnified party, of a release from all liability in respect of such claim or litigation.

(d) The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling Person of such indemnified party and shall survive the Transfer of Registrable Securities.

(e) If the indemnification required by this Section 6 from the indemnifying party is unavailable to an indemnified party hereunder in respect of any losses, claims, damages, liabilities or expenses referred to in this Section 6:

(i) The indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and indemnified parties in connection with the actions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative fault of such indemnifying party and indemnified parties shall be determined by reference to, among other things, whether any violation referred to in this Section 6 has been committed by, or relates to information supplied by, such indemnifying party or indemnified parties, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such violation. The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 6(a) and Section 6(b), any legal or other fees or expenses reasonably incurred by such party in connection with any investigation or proceeding.

(ii) The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 6(e) were determined by a pro rata allocation or by any other method of allocation which does not take into account the equitable considerations referred to in Section 6(e)(i). 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.

7. Holders’ Obligations.

(a) It shall be a condition precedent to the obligations of the Company to include Registrable Securities of any Holder in any Registration Statement or prospectus, as the case may be, that such Holder shall timely furnish to the Company (as a condition precedent to such Holder’s participation in such registration) its Selling Holder Information in accordance with the terms hereof. Each Selling Holder shall timely provide the Company with such information as may be reasonably requested to enable the Company to prepare a supplement or post-effective amendment to any Shelf Registration or a supplement to any prospectus relating to such Shelf Registration.

(b) At the managing underwriter’s request, no Person may participate in any registration hereunder which is underwritten unless such Person (i) agrees to sell such Person’s securities on the basis provided in any underwriting arrangements in customary form approved by the Person or Persons entitled hereunder to approve such arrangements and (ii) completes and executes such underwriting agreement and other documents reasonably required in connection with such underwriting arrangements, provided that no Holder of Registrable Securities included in any underwritten registration shall be required to make any representations or warranties to the Company or the underwriters (other than representations and warranties regarding such Holder

(including with respect to such Holder’s ownership of and title to its Registrable Securities) and such Holder’s intended method of distribution) or to undertake any indemnification obligations to the Company with respect thereto, except as otherwise provided in Section 6(b) hereof, or to the underwriters with respect thereto, except to the extent of the indemnification being given to the Company and its controlling persons in Section 6(b) hereof.

8. Transfer of Registration Rights.

The rights of a Holder hereunder may be Transferred in connection with a Transfer of Registrable Securities to (i) any Affiliate of a Holder, (ii) any subsidiary, parent, partner, retired partner, limited partner, shareholder or member of a Holder or (iii) any family member or trust for the benefit of any Holder, or (iv) any transferee who, after such transfer, holds Registrable Securities representing at least one percent (1.0%) of the Company’s issued and outstanding Common Stock. Notwithstanding the foregoing, such rights may only be Transferred provided that all of the following additional conditions are satisfied: (a) such Transfer is effected in accordance with applicable securities laws; (b) such transferee agrees in writing to become subject to the terms of this Agreement as a Holder; and (c) the Company is given written notice by such Holder of such Transfer, stating the name and address of the transferee and identifying the Registrable Securities with respect to which such rights are being Transferred.

9. Rule 144 and Rule 144A; Other Exemptions

With a view to making available to the Holders of Registrable Securities the benefits of Rule 144 and Rule 144A promulgated under the Securities Act (“Rule 144A”), the Company covenants that it will (i) file in a timely manner all reports and other documents required, if any, to be filed by it under the Securities Act and the Exchange Act and the rules and regulations promulgated thereunder and (ii) make available information necessary to comply with Rule 144 and Rule 144A (if available with respect to resales of the Registrable Securities under the Securities Act), at all times, all to the extent required to enable such Holder to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by (x) Rule 144 and Rule 144A (if available with respect to resales of the Registrable Securities), as such rules may be amended from time to time or (y) any other similar rules or regulations hereafter adopted by the SEC. Upon the reasonable 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 information requirements.

10. Joinder

Any Person who demonstrates that it is a Holder as of the Effective Date (or that it is entitled to become a Holder pursuant to Section 8 hereof) that is not a party hereto may acquire the rights of a Holder hereunder if it agrees in writing to become subject to the terms of this Agreement as a Holder by delivering to the Company a duly executed joinder agreement in form attached hereto as Exhibit A.
