Section 4. Shelf Registration.

(b) No Holder may include any of its Registrable Securities in the Shelf Registration Statement pursuant to this Agreement unless and until such Holder furnishes to the Company in writing, within 30 days after receipt of a written request therefor, the information specified in Item 507 or 508 of Regulation S-K, as applicable, of the Securities Act for use in connection with any Shelf Registration Statement or Prospectus or preliminary Prospectus included therein. Each selling Holder agrees to promptly furnish additional information required to be disclosed in order to make the information previously furnished to the Company by such Holder not materially misleading.

(c) The Company shall use its reasonable best efforts to convert any Shelf Registration Statement that is on a Form S-1 to a Registration Statement on Form S-3 as soon as practicable after the Company is eligible to use Form S-3.

Section 5. Limitations, Conditions and Qualifications to Obligations under Registration Covenants.

(a) The obligations of the Company described in Section 4 and Section 6 of this Agreement are subject to the obligations of the Holders (i) to furnish all information and materials described in Section 3(k) hereof and (ii) to take any and all actions as may be required under Federal and state securities laws and regulations to permit the Company to comply with all applicable requirements of the SEC.

(b) Notwithstanding anything to the contrary in this Agreement, subject to the remainder of this Section 5(b), the Company shall be entitled to postpone the filing of or suspend the effectiveness of, or suspend the rights of any selling Holders Registrable Securities to make sales pursuant to any Registration Statement otherwise required to be prepared, filed and kept effective by it under Section 4 or 6, in the event that, and for a period (a “Blackout Period”) not to exceed an aggregate of 90 days in any 12 month period, (1) an event or circumstance occurs and is continuing as a result of which the Registration Statement, any related Prospectus or any document incorporated therein by reference as then amended or supplemented or proposed to be filed would in the Company’s good faith judgment contain an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, and (2) (a) the Company determines in its good faith judgment that the disclosure of such event or circumstance at such time would reasonably be expected to have a material adverse effect on the Company’s business, operations or prospects or (b) the disclosure otherwise relates to a material business transaction or development that has not yet been publicly disclosed and the Company’s board of directors also determines in good faith, that any disclosure thereof would jeopardize the success of the transaction or that disclosure of the transaction is prohibited by the terms thereof. In addition to the foregoing, prior to the time that the Company becomes eligible to file a registration statement on Form S-3 under the Securities Act, the Company shall be entitled to suspend the effectiveness of the Registration Statement or amendment thereto, or use of a prospectus for a period not to exceed 30 days in any 90 day period only in order to permit the Company to file post-effective amendments to any such registration statement. If the Company shall so postpone the effectiveness of, or suspend the rights of any selling Holders of Registrable Securities to make sales pursuant to, a Registration Statement, it shall, as promptly as possible, notify any selling Holders of Registrable Securities of such determination, and the selling Holders of Registrable Securities shall (y) have the right, in the case of a postponement of the effectiveness of a Registration Statement, upon the affirmative vote of selling Holders of Registrable Securities of not less than a majority of the Registrable Securities to be included in such Registration Statement, to withdraw the request for registration by giving written notice to the Company within 10 days after receipt of such notice or (z) in the case of a suspension of the right to make sales, receive an extension of the registration period referred to in Section 4(a) or Section 6(a) hereof, as applicable, equal to the number of days of the suspension.

(c) Each Holder agrees, if and to the extent requested in writing by the managing underwriter or underwriters in a Public Equity Offering, not to effect any public sale or distribution of Registrable Securities, including a sale pursuant to Rule 144A (except as part of such Public Equity Offering), during the 180 day period following the Company’s initial Public Equity Offering and the 90 day period beginning on the closing date of any other such Public Equity Offering, subject in each case to customary extensions in connection with compliance with NASD Rule 2711. In the event that the Company is not otherwise in compliance with the provisions of this Agreement at the time the Company or such managing underwriter or underwriters send notice pursuant to this Section 5(c), the Holders shall not be required to comply with this Section 5(c). In addition, the provisions of this Section 5(c) shall not apply to any Holder of Registrable Securities if such Holder is prevented by applicable statute or regulation from entering into any such agreement.

Section 6. Piggy-Back Registration of Registrable Securities.

(a) If at any time after the Closing Date the Company proposes to file a Registration Statement under the Securities Act with respect to a Public Equity Offering, then the Company shall give written notice of such proposed filing to the Holders of Registrable Securities as soon as practicable (but in no event fewer than 15 Business Days before the anticipated filing date), and such notice shall offer such Holders the opportunity to register such number of Registrable Securities as each Holder may request in writing within 10 Business Days after receipt of such written notice from the Company (which request shall specify the Registrable Securities intended to be disposed of by such selling Holder of Registrable Securities and the intended method of distribution thereof) (a “Piggy-Back Registration”); provided that any Holder of Warrants so requesting shall agree, upon or prior to the closing of an offering pursuant to any such Registration Statement other than a registration statement filed with the SEC pursuant to Rule 415 under the Securities Act (but in no event earlier than the Separation Date (as defined in the Warrant Agreement)), to exercise their Warrants at least to the extent necessary for such Holder to acquire the number of Registrable Securities for which such Holder has requested registration; provided, further, that no Holder of Registrable Securities shall have “piggy-back” registration rights with respect to their Registrable Securities for any registration statement filed by the Company to register exchange notes for the Notes pursuant to the Registration Rights Agreement, dated as of November 15, 2011, between the Company and the Initial Purchaser. The Company shall use its commercially reasonable efforts to cause the managing underwriter or underwriters, if any, of such proposed offering to permit the Registrable Securities requested to be included in a Piggy-Back Registration to be included on the same terms and conditions as any similar securities of the Company or any other securityholder included therein and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method of distribution thereof. Any selling Holder of Registrable Securities shall have the right to withdraw its request for inclusion of its Registrable Securities in any Shelf Registration Statement pursuant to this Section 6 by giving written notice to the Company of its request to withdraw at any time prior to the filing of such Shelf Registration Statement with the SEC. The Company will pay all registration expenses described in Section 7 hereof in connection with each registration of Registrable Securities requested pursuant to this Section 6, and each Holder of Registrable Securities shall pay all underwriting discounts and commissions and transfer taxes, if any, relating to the sale or disposition of such Holder’s Registrable Securities pursuant to a Piggy-Back Registration effected pursuant to this Section 6.

No registration effected under this Section 6, and no failure to effect a registration under this Section 6, shall relieve the Company of its obligations to effect a registration pursuant to Section 4 hereof of any Registrable Securities not included in such Piggy-Back Registration, and no failure to effect a registration required under this Section 6 and to complete the sale of securities registered thereunder in connection therewith shall relieve the Company of any other obligation under this Agreement.

(b) Priority in Piggy-Back Registration. In a registration pursuant to this Section 6 involving an underwritten offering, if the managing underwriter or underwriters of such underwritten offering have informed, in writing, the Company and the selling Holders of Registrable Securities requesting inclusion in such offering that in such underwriter’s or underwriters’ opinion the total number of securities which the

Company, the selling Holders of Registrable Securities and any other Persons desiring to participate in such registration intend to include in such offering is such as to adversely affect the success of such offering, including the price at which such securities can be sold, then the Company will be required to include in such registration only the amount of securities which it is so advised should be included in such registration. In such event: (x) in cases initially involving the registration for sale of securities for the Company’s own account, securities shall be registered in such offering in the following order of priority: (i) first, the securities which the Company proposes to register, (ii) second, provided that no securities proposed to be registered by the Company have been excluded from such registration, the securities that have been requested to be included in such registration statement by the selling Holders of Registrable Securities pursuant to this Agreement and other Persons that have “piggy-back” registration rights pursuant to contractual commitments of the Company in effect as of the date of this Agreement (pro rata based on the amount of securities sought to be registered by such Holders and other Persons or otherwise giving effect to any registration priorities under contractual commitments of the Company existing and in effect as of the date of this Agreement), and (iii) third, provided that no securities sought to be included by the selling Holders of Registrable Securities have been excluded from such registration, the securities of other Persons entitled to exercise “piggy-back” registration rights pursuant to contractual commitments of the Company (pro rata based on the amount of securities sought to be registered by such Persons); and (y) in cases initially involving the registration for sale of securities pursuant to “demand” registration rights, securities shall be registered in such offering in the following order of priority: (i) first, the securities of any Person whose exercise of a “demand” registration right pursuant to a contractual commitment of the Company is the basis for the registration, (ii) second, provided that no securities of any Person whose exercise of a “demand” registration right pursuant to a contractual commitment of the Company is the basis for such registration have been excluded from such registration, the securities requested to be included in such registration by the selling Holders of Registrable Securities pursuant to this Agreement and other Persons that have “piggy-back” registration rights pursuant to contractual commitments of the Company in effect as of the date of this Agreement (pro rata based on the amount of securities sought to be registered by such Holders and other Persons or otherwise giving effect to any registration priorities under contractual commitments of the Company existing and in effect as of the date of this Agreement), (iii) third, provided that no securities sought to be included by the selling Holders of Registrable Securities have been excluded from such registration, securities of other Persons entitled to exercise “piggy-back” registration rights pursuant to contractual commitments of the Company (pro rata based on the amount of securities sought to be registered by such Persons) and (iv) fourth, provided that no securities sought to be included by other Persons entitled to exercise “piggy-back” registration rights pursuant to such contractual commitments have been excluded from such registration, any securities which the Company proposes to register.

(c) Exclusion of Registrable Securities. The Company shall not be required by this Section 6 to include Registrable Securities in a Piggy-Back Registration if in the written opinion of outside counsel to the Company, addressed to the Holders of Registrable Securities and delivered to them, the Holders of such Registrable Securities seeking registration would be free to sell all such Registrable Securities without registration under Rule 144, which opinion may be based in part upon the representation by the Holders of such Registrable Securities seeking registration, which representation shall not be unreasonably withheld, that each such Holder is not an affiliate of the Company within the meaning of the Securities Act.

In connection with any Registration Statement, Prospectus or form of prospectus, any amendment or supplement thereto, or any preliminary prospectus or Free Writing Prospectus in which a Holder is participating, such Holder, severally and not jointly with other Holders, shall indemnify and hold harmless the Company, its directors and each Person, if any, who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20(a) of the Exchange Act), and the directors, officers and partners of such controlling persons, to the fullest extent lawful, from and against all Losses arising out of or based upon any untrue or alleged untrue statement of a material fact contained in any Registration Statement, Prospectus or form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus or Free Writing Prospectus, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading to the extent, but only to the extent, that such losses are finally judicially determined by a court of competent jurisdiction in a final, unappealable order to have resulted solely from an untrue statement or alleged untrue statement of a material fact or omission or alleged omission of a material fact contained in or omitted from any information so furnished in writing by such Holder to the Company expressly for use therein. Notwithstanding the foregoing, in no event shall the liability of any selling Holder be greater in amount than such Holder’s Maximum Contribution Amount (as defined below).

(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 party or parties from which such indemnity is sought (the “Indemnifying Party” or “Indemnifying Parties”, as applicable) in writing; but the omission to so notify the Indemnifying Party (i) will not relieve such Indemnifying Party from any liability under paragraph (a) or (b) above unless and only to the extent it is materially prejudiced as a result thereof and (ii) will not, in any event, relieve the Indemnifying Party from any obligations to any Indemnified Party other than the indemnification obligation provided in paragraphs (a) and (b) above.

The Indemnifying Party shall have the right, exercisable by giving written notice to an Indemnified Party, within 20 Business Days after receipt of written notice from such Indemnified Party of such proceeding, to assume, at its expense, the defense of any such proceeding; provided, that 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 to pay such fees and expenses in writing; (2) the Indemnifying Party shall have failed promptly to assume the defense of such proceeding or shall have failed to employ counsel reasonably satisfactory to such Indemnified Party; or (3) the named parties to any such proceeding (including any impleaded parties) include both such Indemnified Party and the Indemnifying Party or any of its affiliates or controlling persons, and such Indemnified Party shall have been advised by counsel that there may be one or more defenses available to such Indemnified Party that are in addition to, or in conflict with, those defenses available to the Indemnifying Party or such affiliate or controlling person (in which case, if such Indemnified Party notifies the Indemnifying Parties in writing that it elects to employ separate counsel at the expense of the Indemnifying Parties, the Indemnifying Parties shall not have the right to assume the defense and the reasonable fees and expenses of such counsel shall be at the expense of the Indemnifying Party; it being understood, however, that, the Indemnifying Party shall not, in connection with any one such proceeding or separate but substantially similar or related proceedings in the same jurisdiction, arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (together with appropriate local counsel) at any time for such Indemnified Party).

No Indemnifying Party shall be liable for any settlement of any such proceeding effected without its written consent, which shall not be unreasonably withheld, but if settled with its written consent, or if there be a final judgment for the plaintiff in any such proceeding, each Indemnifying Party jointly and severally agrees, subject to the exceptions and limitations set forth above, to indemnify and hold harmless each Indemnified Party from and against any and all Losses by reason of such settlement or judgment. The Indemnifying Party shall not consent to the entry of any judgment or enter into any settlement unless such judgment or settlement (i) includes as an unconditional term thereof the giving by the claimant or plaintiff to each Indemnified Party of a release, in form and substance reasonably satisfactory to the Indemnified Party, from all liability in respect of such proceeding for which such Indemnified Party would be entitled to indemnification hereunder (whether or not any Indemnified Party is a party thereto) and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any Indemnified Party.

(d) Contribution. If the indemnification provided for in this Section 8 is unavailable to an Indemnified Party or is insufficient to hold such Indemnified Party harmless for any Losses in respect of which this Section 8 would otherwise apply by its terms (other than by reason of exceptions provided in this Section 8), then each applicable Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall have a joint and several obligation to contribute to the amount paid or payable by such Indemnified Party as a result of such Losses, 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 such Indemnifying Party, on the one hand, and Indemnified Party, on the other hand, shall be determined by reference to, among other things, whether any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact 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 any such statement or omission. The amount paid or payable by an Indemnified Party as a result of any Losses shall be deemed to include any legal 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 Section 8(a) or 8(b) was available to such party.

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 8(d) were determined by pro rata allocation or by other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding

the provisions of this Section 8(d), a selling Holder shall not be required to contribute, in the aggregate, any amount in excess of such Holder’s Maximum Contribution Amount. A selling Holder’s “Maximum Contribution Amount” shall equal the excess of (i) the aggregate proceeds received by such Holder pursuant to the sale of such Registrable Securities over (ii) the aggregate amount of damages 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 guilty of such fraudulent misrepresentation. The Holders’ obligations to contribute pursuant to this Section 8(d) are several in proportion to the respective number of Registrable Securities held by each Holder hereunder and not joint.

The indemnity and contribution agreements contained in this Section 8 are in addition to any liability that the Indemnifying Parties may have to the Indemnified Parties.

Section 9. Rule 144A and Rule 144.

The Company covenants that it shall (a) file the reports required to be filed by it (if so required) under the Securities Act and the Exchange Act in a timely manner and, if at any time the Company is not required to file such reports, it will, upon the written request of any Holder of Registrable Securities, make publicly available other information necessary to permit sales pursuant to Rule 144 and 144A and (b) take such further action as any Holder may reasonably request in writing, all to the extent required from time to time to enable such Holder to sell Registrable Securities without registration under the Securities Act pursuant to the exemptions provided by Rule 144 and Rule 144A. Upon the request of any Holder, the Company shall deliver to such Holder a written statement as to whether it has complied with such information and requirements.

Section 10. Miscellaneous.

(a) Remedies. The Company acknowledges and agrees that any failure by the Company to comply with its obligations under Section 4 and Section 6 hereof may result in material irreparable injury to the Holders for which there is no adequate remedy at law, that it will not be possible to measure damages for such injuries precisely and that, in the event of any such failure, any Holder may obtain such relief as may be required to specifically enforce the Company’s obligations under Section 4 and Section 6 hereof.

(b) No Inconsistent Agreements. The Company has not granted any person registration rights with respect to its securities (other than as set forth in this Agreement and the Registration Rights Agreement, dated as of November 15, 2011, between the Company and the Initial Purchaser) and will not on or after the date of this Agreement enter into any agreement with respect to its securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof. The Company has not entered and will not enter into any agreement with respect to any of its securities that will grant to any Person piggy-back rights with respect to the Shelf Registration Statement.

(c) Amendments and Waivers. The provisions of this Agreement may not be amended, modified or supplemented, and waivers or consents to or departures from the provisions hereof may not be given, other than with the prior written consent of the Holders of not less than a majority of the Registrable Securities outstanding in circumstances that would adversely affect any Holders of Registrable; provided, however, that Section 8 and this Section 10(c) may not be amended, modified or supplemented without the prior written consent of each Holder.

(j) Severability.
