Section 2. Registration Statement.

(a) As soon as practicable after the date hereof (and in no event later than the date that the definitive Proxy Statement has been filed with the SEC), the Company will prepare and file and use reasonable efforts to cause to be declared effective or otherwise become effective pursuant to the Securities Act (the “Registration Date”) a Registration Statement or post-effective amendment to an existing Registration Statement in order to provide for resales of Registrable Securities to be made on a delayed or continuous basis pursuant to Rule 415 under the Securities Act (the “Initial Registration Statement”). By the Registration Date, the Company shall prepare and file a supplemental listing application with the Nasdaq to list the Registrable Securities covered by the Initial Registration Statement and shall use its reasonable best efforts to have such Registrable Securities approved for listing on the Nasdaq, subject only to official notice of issuance. In addition, the Company will from time to time use reasonable efforts to file such additional Registration Statements to cover resales of any Registrable Securities that are not registered for resale pursuant to a the Initial Registration Statement and will use its reasonable efforts to cause such Registration Statement to be declared effective or otherwise to become effective under the Securities Act and will use its reasonable efforts to keep the Registration Statement continuously effective under the Securities Act at all times until the Registration Termination Date. Any Registration Statement filed pursuant to this Section 2 shall cover only Registrable Securities, shall be on Form S-3 (or a successor form) if the Company is eligible to use such form and shall be an automatically effective Registration Statement if the Company is a WKSI.

(b) Subject to the provisions of Section 3, the Company will use its reasonable efforts to keep the initial Registration Statement (or any replacement Registration Statement) continuously effective until the earlier of (such earlier date, the “Registration Termination Date”): (i) the date on which all Registrable Securities covered by the Registration Statement have been sold thereunder in accordance with the plan and method of distribution disclosed in the prospectus included in the Registration Statement, (ii) there otherwise cease to be any Registrable Securities and (iii) if the Company consolidates or merges with or into any Person in a transaction that constitutes a Make-Whole Fundamental Change and the Company Common Stock is, in whole or in part, converted into or exchanged for securities of a different issuer and/or cash in a transaction that will constitute a Change in Control and the shares of Company Common Stock are delisted from Nasdaq.

(c) From and after the date hereof until the Registration Termination Date, the Company shall use its reasonable efforts to maintain eligibility to be able to file and use a Registration Statement on Form S-3 (or any successor form thereto). Notwithstanding anything herein to the contrary, during such period of time from and after the Registration Date that the Company ceases to be eligible to file or use a Registration Statement on

Form S-3 (or any successor form thereto), upon the written request of any holder or holders of Registrable Securities, the Company shall use its reasonable efforts to file a Registration Statement on Form S-1 (or any successor form) under the Securities Act covering the Registrable Securities of the requesting party or parties, as applicable, and use reasonable efforts to cause such Registration Statement to be declared effective pursuant to the Securities Act as soon as reasonably practicable after filing thereof. Each such written request must specify the amount and intended manner of disposition of such Registrable Securities; provided, that the minimum amount of such Registrable Securities shall be $75,000,000. Any Registration Statement required to be filed pursuant to this Section 2(c) shall not be required to cover Registrable Securities to be offered on a delayed or continuous basis pursuant to Rule 415 under the Securities Act. The obligations of the Company under this Section 2(c) shall not impact the obligations of the Company under Section 2(a) which shall continue to be in force.

Section 3. Registration Limitations and Obligations.

(a) Subject to Section 2, the Company will use reasonable efforts to prepare such supplements or amendments (including a post-effective amendment), if required by applicable law, to each applicable Registration Statement and file any other required document so that such Registration Statement will be Available at all times during the period for which such Registration Statement is, or is required pursuant to this Agreement to be, effective; provided, that no such supplement, amendment or filing will be required during a Blackout Period. Notwithstanding anything to the contrary contained in this Agreement, the Company shall be entitled, from time to time, by providing written notice to the holders of Registrable Securities, to require such holders of Registrable Securities to suspend the use of the prospectus for sales of Registrable Securities under the Registration Statement during any Blackout Period; provided, for purposes of this Section 3, the Company shall only be obligated to provide written notice to any holder or Beneficial Owner of Registrable Securities of any such Blackout Period if such holder or Beneficial Owner has specified in writing to the Company for purposes of receiving such notice such holder’s or Beneficial Owner’s address, contact and fax number information. No sales may be made under the applicable Registration Statement during any Blackout Period (with respect to clause (ii) of the definition thereof, of which the holders of Registrable Securities have or are deemed to have received notice). In the event of a Blackout Period under clause (ii) of the definition thereof, the Company shall (x) deliver to the holders of Registrable Securities a certificate signed by the chief executive officer, chief financial officer, general counsel or treasurer of the Company confirming that the conditions described in clause (ii) of the definition of Blackout Period are met, which certificate shall contain an approximation of the anticipated delay, and (y) notify each holder of Registrable Securities promptly upon each of the commencement and the termination of each Blackout Period, which notice of termination shall be delivered to each holder of Registrable Securities no later than the close of business of the last day of the Blackout Period. In connection with the expiration of any Blackout Period and without any further request from a holder of Registrable Securities, the Company to the extent necessary and as required by applicable law shall as promptly as reasonably practicable prepare supplements or amendments, including a post-effective amendment, to the Registration Statement or the prospectus, or any document incorporated therein by reference, or file any other required document so that the Registration Statement will be Available. A Blackout Period described in clause (ii) of the definition thereof shall be deemed to have expired when the Company has notified the holders of Registrable Securities that the Blackout Period is over and the Registration Statement is Available. Notwithstanding anything in this Agreement to the contrary, the absence of an Available Registration Statement at any time from and after the Registration Date shall be considered a Blackout Period described in clause (ii) of the definition thereof and subject to the limitations therein, except to the extent such absence occurs during (and does not extend beyond) a Blackout Period described in clause (i) of the definition thereof. For avoidance of doubt, upon expiration of a Blackout Period described in clause (i) of the definition thereof, any additional duration of a Blackout Period will be deemed to a Blackout Period described in clause (ii) of the definition thereof and subject to the limitations therein.

(b) At any time that a Registration Statement is effective and prior to the Registration Termination Date, if a holder of Registrable Securities delivers a notice to the Company (a “Take-Down Notice”) stating that it, together with any other holder of Registrable Securities, intend to sell at least $75,000,000 in aggregate of Registrable Securities held by such holder and such other holders (provided that, if the holders of Registrable Securities and their Affiliates do not collectively own at least $75,000,000 of Registrable Securities, they shall be permitted to deliver a Take-Down Notice to sell all of the Registrable Securities held by them (but such amount may not in any case be less than $25,000,000 collectively of Registrable Securities), in each case,

pursuant to the Registration Statement, then, the Company shall amend or supplement the Registration Statement as may be necessary and to the extent required by law so that the Registration Statement remains Available in order to enable such Registrable Securities to be distributed in an Underwritten Offering. In connection with any Underwritten Offering of Registrable Securities for which a holder delivers a Take-Down Notice and satisfies the dollar thresholds set forth in first sentence above, and where the Take-Down Notice contemplates marketing efforts not to exceed twenty-four (24) hours by the Company and the underwriters, the Company will use reasonable efforts to cooperate and make its senior officers available for participation in such marketing efforts (which marketing efforts will not, for the avoidance of doubt, include a “road show” requiring such officers to travel outside of the city in which they are primarily located). The holder of Registrable Securities that delivered the applicable Take-Down Notice shall select the underwriter(s) for the Underwritten Offering; provided that the managing underwriter(s) (if there is only one underwriter, such underwriter shall be deemed to be the managing underwriter) shall be reasonably acceptable to the Company. The Company shall select the counsel for the managing underwriter(s); provided that such counsel shall be reasonably acceptable to the underwriter(s) and the holder of Registrable Securities that delivered the applicable Take-Down Notice. Such holder shall determine the pricing of the Registrable Securities offered pursuant to any such Registration Statement, including the underwriting discount and fees payable by such holder to the underwriters in such Underwritten Offering. Such holder shall reasonably determine the timing of any such registration and sale. Such holder shall determine the applicable underwriting discount and other financial terms, and such holder of the Registrable Securities sold in the Underwritten Offering shall be solely responsible for all such discounts and fees payable to such underwriters in such Underwritten Offering. Without the consent of the applicable holder of Registrable Securities subject to an Underwritten Offering, no Underwritten Offering pursuant to this Agreement shall include any securities other than Registrable Securities.

(c) Notwithstanding anything herein to the contrary, (i) if holders of Registrable Securities engage or propose to engage in a “distribution” (as defined in Regulation M under the Exchange Act) of Registrable Securities, such holders shall discuss the timing of such distribution with the Company reasonably prior to commencing such distribution, and (ii) such distribution must not be for less than $75,000,000 of Registrable Securities held by such holders (provided that, if collectively the holders of Registrable Securities and their Affiliates do not own at least $75,000,000 of Registrable Securities, they shall be permitted to engage in such distribution with respect to all of the Registrable Securities held by them (for so long as they hold collectively at least $25,000,000 of Registrable Securities)).

(d) In connection with a distribution of Registrable Securities in which the holders of Registrable Securities are selling an aggregate of at least $200,000,000 of Registrable Securities, the Company shall, to be extent requested by managing underwriter(s) of such a distribution, be subject to a restricted period of the same length of time as such holder agrees with the managing underwriter(s) (but not to exceed 90 days) during which the Company may not offer, sell or grant any option to purchase Company Common Stock (in the case of an offering of Company Common Stock or securities convertible or exchangeable for Company Common Stock) and any debt securities (in the case of an offering of debt securities) of the Company, subject to customary carve-outs that include, but are not limited to, (i) issuances pursuant to the Company’s employee or director stock plans and issuances of shares upon the exercise of options or other equity awards under such stock plans and (ii) in connection with acquisitions, joint ventures and other strategic transactions (subject to, in the case of this clause (ii), a limit not to exceed 10% of the Company’s then outstanding Company Common Stock).

Section 4. Registration Procedures.

(a) If and whenever the Company is required to use reasonable efforts to effect the registration of any Registrable Securities under the Securities Act and in connection with any distribution of Registered Securities pursuant thereto as provided in this Agreement (including any sale referred to in any Take-Down Notice), the Company shall as promptly as reasonably practicable, subject to the other provisions of this Agreement:

(i) use reasonable efforts to prepare and file with the SEC a Registration Statement to effect such registration in accordance with the intended method or methods of distribution of such securities and thereafter use reasonable efforts to cause such Registration Statement to become and remain effective pursuant to the terms of this Exhibit A; provided, however, that the Company may discontinue any registration of its securities which are not Registrable Securities at any time prior to the effective date of the Registration Statement relating thereto; provided, further, that before filing such registration statement or any amendments or supplements thereto, including any prospectus supplements in connection with a sale

referred to in a Take-Down Notice, the Company will furnish to the holders which are including Registrable Securities in such registration (“Selling Holders”) and the lead managing underwriter(s), if any, copies of all such documents proposed to be filed, which documents will be subject to the review and reasonable comment (which comments will be considered in good faith by the Company) of the counsel (if any) to such holders and counsel (if any) to such underwriter(s), and other documents reasonably requested by any such counsel, including any comment letter from the SEC, and, if requested by any such counsel, provide such counsel and the lead managing underwriter(s), if any, reasonable opportunity to participate in the preparation of such Registration Statement and each prospectus (including any prospectus supplement) included or deemed included therein and such other opportunities to conduct a customary and reasonable due diligence investigation (in the context of a registered underwritten offering) of the Company, including reasonable access to (including responses to any reasonable inquiries by the lead managing underwriter(s) and their counsel) the Company’s books and records, officers, accountants and other advisors;

(ii) prepare and file with the SEC such amendments and supplements to such Registration Statement and the prospectus used in connection therewith as may be necessary and to the extent required by applicable law to keep such Registration Statement effective and Available pursuant to the terms of this Exhibit A;

(iv) furnish to the Selling Holders and each underwriter, if any, of the securities being sold by such Selling Holders such number of conformed copies of such Registration Statement and of each amendment and supplement thereto, such number of copies of the prospectus and any prospectus supplement contained in or deemed part of such Registration Statement (including each preliminary prospectus supplement) and each free writing prospectus (as defined in Rule 405 of the Securities Act) (a “Free Writing Prospectus”) utilized in connection therewith and any other prospectus filed under Rule 424 under the Securities Act, in conformity with the requirements of the Securities Act, and such other documents as such Selling Holders and underwriter(s), if any, may reasonably request in order to facilitate the public sale or other disposition of the Registrable Securities owned by such Selling Holders;

(v) use reasonable efforts to cause such Registrable Securities to be listed on each securities exchange on which similar securities issued by the Company are then listed;

(vi) use reasonable efforts to provide and cause to be maintained a transfer agent and registrar for all Registrable Securities covered by such Registration Statement from and after a date not later than the effective date of such Registration Statement;

(vii) as promptly as practicable notify in writing the holders of Registrable Securities and the underwriters, if any, of the following events: (A) the filing of the Registration Statement, any amendment thereto, the prospectus or any prospectus supplement related thereto or post-effective amendment to such Registration Statement or any Free Writing Prospectus utilized in connection therewith, and, with respect to such Registration Statement or any post-effective amendment thereto, when the same has become effective; (B) any request by the SEC or any other U.S. or state governmental authority for amendments or supplements to such Registration Statement or the prospectus or for additional information; (C) the issuance by the SEC of any stop order suspending the effectiveness of such Registration Statement or the initiation of any proceedings by any person for that purpose; (D) the receipt by the Company of any notification with respect to the suspension of the qualification of any Registrable Securities for sale under the securities or “blue sky” laws of any jurisdiction or the initiation or threat of any proceeding for such purpose; (E) if at any time the representations and warranties of the Company contained in any agreement (including any underwriting agreement) related to such registration cease to be true and correct in any material respect; and (F) upon the happening of any event that makes any statement made in such Registration Statement or related prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires the making of any changes

in such registration statement, prospectus or documents so that, in the case of such Registration Statement, 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 not misleading, and that in the case of the prospectus, it will not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading;

(viii) use reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of such Registration Statement, or the lifting of any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction at the earliest reasonable practicable date, except that the Company shall not for any such purpose be required to (A) qualify generally to do business as a foreign corporation or as a dealer in securities in any jurisdiction wherein it would not but for the requirements of this clause (ix) be obligated to be so qualified, (B) subject itself to taxation in any such jurisdiction or (C) file a general consent to service of process in any such jurisdiction;

(c) Any Person entitled to indemnification hereunder shall give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification; provided, however, the failure to give such notice shall not release the indemnifying party from its obligation, except to the extent that the indemnifying party has been actually and materially prejudiced by such failure to provide such notice on a timely basis.

(d) In any case in which any such action is brought against any indemnified party, the indemnified party shall promptly notify in writing the indemnifying party of the commencement thereof, and the indemnifying party will be entitled to participate therein, and, to the extent that it may wish, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof and acknowledging the obligations of the indemnifying party with respect to such proceeding, the indemnifying party will not (so long as it shall continue to have the right to defend, contest, litigate and settle the matter in question in accordance with this paragraph) be liable to such indemnified party hereunder for any legal or other expense subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation, supervision and monitoring (unless (i) such indemnified party reasonably objects to such assumption on the grounds that there may be defenses available to it which are different from or in addition to the defenses available to such indemnifying party and, as a result, a conflict of interest exists or (ii) the indemnifying party shall have failed within a reasonable period of time to assume such defense and the indemnified party is or would reasonably be expected to be materially prejudiced by such delay, in either event the indemnified party shall be promptly reimbursed by the indemnifying party for the expenses incurred in connection with retaining one separate legal counsel (for the avoidance of doubt, for all indemnified parties in connection therewith)). For the avoidance of doubt, notwithstanding any such assumption by an indemnifying party, the indemnified party shall have the right to employ separate counsel in any such matter and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such indemnified party except as provided in the previous sentence. An indemnifying party shall not be liable for any settlement of an action or claim effected without its consent (which consent shall not be unreasonably withheld, conditioned or delayed). No matter shall be settled by an indemnifying party without the consent of the indemnified party (which consent shall not be unreasonably withheld, conditioned or delayed), unless such settlement (x) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such claim or proceeding, (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any indemnified party and (z) is settled solely for cash for which the indemnified party would be entitled to indemnification hereunder. The failure of an indemnified party to give notice to an indemnifying party of any action brought against such indemnified party shall not relieve the indemnifying party of its obligations or liabilities pursuant to this Agreement, except to the extent such failure adversely prejudices the indemnifying party.

(e) The indemnification provided for under this Agreement shall survive the sale or other transfer of the Registrable Securities and the termination of this Agreement.

(f) If recovery is not available under the foregoing indemnification provisions for any reason or reasons other than as specified therein, any Person who would otherwise be entitled to indemnification by the terms thereof shall nevertheless be entitled to contribution with respect to any Losses with respect to which such Person would be entitled to such indemnification but for such reason or reasons, in such proportion as is appropriate to reflect the relative fault of the indemnifying party, on the one hand, and such indemnified party, on the other hand, in connection with the actions, statements or omissions that resulted in such Losses as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party, the Persons’ relative knowledge and access to information concerning the matter with respect to which the claim was asserted, the opportunity to correct and prevent any statement or omission, and other equitable considerations appropriate under the circumstances. It is hereby agreed that it would not necessarily be equitable if the amount of such contribution were determined by pro rata or per capita allocation that does not take into account the equitable considerations referred to in the immediately preceding sentence. Notwithstanding any other provision of this Agreement, no holder of Registrable Securities shall be required to contribute, in the aggregate, any amount in excess of its net proceeds from the sale of the Registrable Securities subject to any actions or proceedings over the amount of any damages, indemnity or

contribution that such holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not found guilty of such fraudulent misrepresentation.

(g) The indemnification and contribution agreements contained in this Section 6 are in addition to any liability that the indemnifying party may have to the indemnified party and do not limit other provisions of this Agreement that provide for indemnification.

Section 7. Facilitation of Sales Pursuant to Rule 144. For as long as any holder holds Registrable Securities, to the extent it shall be required to do so under the Exchange Act, the Company shall use reasonable efforts to timely file the reports required to be filed by it under the Exchange Act or the Securities Act (including the reports under Sections 13 and 15(d) of the Exchange Act referred to in subparagraph (c)(1) of Rule 144) and submit all required Interactive Data Files (as defined in Rule 11 of Regulation S-T of the Commission), and shall use reasonable efforts to take such further necessary action as any holder of Registrable Securities may reasonably request in connection with the removal of any restrictive legend on the Registrable Securities being sold, all to the extent required from time to time to enable such holder to sell the Registrable Securities without registration under the Securities Act within the limitations of the exemption provided by Rule 144.

Section 8. Transfer or Assignment of Registration Rights. The rights to cause the Company to register Registrable Securities under this Exhibit A may not be transferred or assigned except pursuant to this Section 8. Notwithstanding anything herein to the contrary, nothing in this Agreement shall restrict transfers of Registrable Securities to any lenders under the Margin Agreement or any of the Security Agreements, or a collateral agent on behalf thereof. The Stockholders may transfer or assign their rights pursuant to this Agreement to (i) any of their Affiliates and (ii) the lenders and collateral agent under the Margin Agreement or any similar financing arrangement.
