The Company shall use its commercially reasonable efforts to complete the Exchange Offer as provided above and shall comply with the applicable requirements of the Securities Act, the Exchange Act and other applicable laws and regulations in connection with the Exchange Offer.  The Exchange Offer shall not be subject to any conditions, other than that the Exchange Offer does not violate any applicable law or applicable interpretations of the Staff.

(b)                                 In the event that (i) the Company determines that the Exchange Offer Registration provided for in Section 2(a) above is not available or may not be completed as soon as practicable after the last Exchange Date because it would violate any applicable law or applicable interpretations of the Staff, (ii) the Exchange Offer is not for any other reason completed by the Target Registration Date, or (iii) upon receipt of a request by any Holder of Registrable Securities that (A) is prohibited by applicable law or SEC policy from participating in the Exchange Offer or (B) may not resell the Exchange Securities acquired by it in the Exchange Offer to the public without delivering a prospectus and that the Prospectus contained in the Exchange Offer Registration Statement is not appropriate or available for such resales by such Holder or (iv) any Initial Purchaser shall so request (a “Shelf Request”) in connection with any offer or sale of Registrable Securities that are ineligible to be exchanged in the Exchange Offer, the Company shall use its commercially reasonable efforts to cause to be filed as soon as practicable after such determination, date or Shelf Request, as the case may be, a Shelf Registration Statement providing for the sale of all the Registrable Securities by the Holders thereof and to have such Shelf Registration Statement become effective under the Securities Act.

The Company agrees to use its commercially reasonable efforts to keep the Shelf Registration Statement continuously effective for one year or such shorter period that will terminate when all the Registrable Securities covered by the Shelf Registration Statement have been sold pursuant to the Shelf Registration Statement (the “Shelf Effectiveness Period”).  The Company further agrees to supplement or amend the Shelf Registration Statement and the related Prospectus if required by the rules, regulations or instructions applicable to the registration form

used by the Company for such Shelf Registration Statement or by the Securities Act or by any other rules and regulations thereunder for shelf registration or if reasonably requested by a Holder of Registrable Securities with respect to information relating to such Holder, and to use its commercially reasonable efforts to cause any such amendment to become effective under the Securities Act, if required, and such Shelf Registration Statement and Prospectus to become usable as soon as practicable thereafter.  The Company agrees to furnish to the Holders of Registrable Securities copies of any such supplement or amendment promptly after its being used or filed with the SEC.

(c)                                  The Company shall pay all Registration Expenses in connection with any registration pursuant to Section 2(a) or Section 2(b) hereof.  Each Holder shall pay all underwriting discounts and commissions, brokerage commissions and transfer taxes, if any, relating to the sale or disposition of such Holder’s Registrable Securities pursuant to the Shelf Registration Statement.

(d)                                 An Exchange Offer Registration Statement pursuant to Section 2(a) hereof will not be deemed to have become effective unless it has been declared effective by the SEC. A Shelf Registration Statement pursuant to Section 2(b) will not be deemed to have become effective unless it has been declared effective by the SEC or is automatically effective upon filing with the SEC as provided by Rule 462 under the Securities Act.

In the event that (i) either the Exchange Offer is not completed or the Shelf Registration Statement, if required pursuant to Section 2(b)(i) or 2(b)(ii) hereof, is not declared effective on or prior to the Target Registration Date, or (ii) the Company receives a Shelf Request pursuant to Section 2(b)(iii) or 2(b)(iv) hereof, and the Shelf Registration Statement required to be filed thereby is not declared effective by the SEC by the later of (x) October 20, 2013 or (y) 90 days after the delivery of such Shelf Request (such later date, the “Shelf Additional Interest Date”), then the interest rate on the Registrable Securities will be increased by (A) 0.25% per annum for the first 90-day period immediately following the Target Registration Date or the Shelf Additional Interest Date, as applicable, and (B) an additional 0.25% per annum with respect to each subsequent 90-day period, in each case until the Exchange Offer is completed or the Shelf Registration Statement, if required hereby, has become effective under the Securities Act or the Securities no longer qualify as Registrable Securities, up to a maximum of 1.00% per annum of additional interest.

If the Shelf Registration Statement, if required hereby, has become effective under the Securities Act and thereafter either ceases to be effective or the Prospectus contained therein ceases to be usable at any time during the Shelf Effectiveness Period, and such failure to remain effective or usable exists for more than 30 days (whether or not consecutive) in any 12-month period, then the interest rate on the Registrable Securities will be increased by (i) 0.25% per annum commencing on the 31st day in such 12-month period and (ii) an additional 0.25% per annum with respect to each subsequent 90-day period (whether or not consecutive) and ending on such date that the Shelf Registration Statement has again become effective under the Securities Act or the Prospectus again becomes usable, up to a maximum of 1.00% per annum of additional interest.

7

(e)                                  Any additional interest paid in accordance with this Section 2 shall be liquidated damages and shall be the sole and exclusive remedy available to Holders due to a failure by the Company to comply with its obligations under Section 2(a) and Section 2(b).

The Company may give any such notice only twice during any 365-day period and any such suspensions shall not exceed 30 days for each suspension and there shall not be more than two suspensions in effect during any 365-day period.

(e)                                  The Holders of Registrable Securities covered by a Shelf Registration Statement who desire to do so may sell such Registrable Securities in an Underwritten Offering.  In any such Underwritten Offering, the investment bank or investment banks and manager or managers (each an “Underwriter”) that will administer the offering will be selected by the Holders of a majority in principal amount of the Registrable Securities included in such offering; provided that, with respect to any Underwriter other than the Representatives, such selections shall be subject to the approval of the Company, which approval shall not be unreasonably withheld.

4.                                      Participation of Broker-Dealers in Exchange Offer.  (a)  The Staff has taken the position that any broker-dealer that receives Exchange Securities for its own account in the Exchange Offer in exchange for Securities that were acquired by such broker-dealer as a result of market-making or other trading activities (a “Participating Broker-Dealer”) may be deemed to be an “underwriter” within the meaning of the Securities Act and must deliver a prospectus

12

meeting the requirements of the Securities Act in connection with any resale of such Exchange Securities.

The Company understands that it is the Staff’s position that if the Prospectus contained in the Exchange Offer Registration Statement includes a plan of distribution containing a statement to the above effect and the means by which Participating Broker-Dealers may resell the Exchange Securities, without naming the Participating Broker-Dealers or specifying the amount of Exchange Securities owned by them, such Prospectus may be delivered by Participating Broker-Dealers (or, to the extent permitted by law, made available to purchasers) to satisfy their prospectus delivery obligation under the Securities Act in connection with resales of Exchange Securities for their own accounts, so long as the Prospectus otherwise meets the requirements of the Securities Act.

(b)                                 In light of the above, and notwithstanding the other provisions of this Agreement, the Company agrees, upon request of any Participating Broker-Dealer, to amend or supplement the Prospectus contained in the Exchange Offer Registration Statement for a period of up to 180 days after the last Exchange Date (as such period may be extended pursuant to Section 3(d) of this Agreement), in order to expedite or facilitate the disposition of any Exchange Securities by Participating Broker-Dealers consistent with the positions of the Staff recited in Section 4(a) above.  The Company further agrees that Participating Broker-Dealers shall be authorized to deliver such Prospectus (or, to the extent permitted by law, make available) during such period in connection with the resales contemplated by this Section 4.

(c)                                  The Initial Purchasers shall have no liability to the Company or any Holder with respect to any request that they may make pursuant to Section 4(b) above.

5.                                      Indemnification and Contribution.  (a)  The Company agrees to indemnify and hold harmless each Initial Purchaser and each Holder, their respective affiliates, directors, officers and employees and each Person, if any, who controls any Initial Purchaser or any Holder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any loss, claim, damage, liability or expense, as incurred, to which such Initial Purchaser, Holder, affiliate, director, officer, employee or controlling Person may become subject, under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Company), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon: (1) any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary in order to make the statements therein not misleading, or (2) any untrue statement or alleged untrue statement of a material fact contained in any Prospectus, any Free Writing Prospectus or any “issuer information” (“Issuer Information”) filed or required to be filed pursuant to Rule 433(d) under the Securities Act, or any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case except insofar as such loss, claim, damage, liability or expense arises out of, or is based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Initial Purchaser or information relating to any Holder furnished

13

to the Company in writing through the Representatives or any selling Holder, respectively, expressly for use therein.  In connection with any Underwritten Offering permitted by Section 3, the Company will also indemnify the Underwriters, if any, selling brokers, dealers and similar securities industry professionals participating in the distribution, their respective affiliates and each Person who controls such Persons (within the meaning of the Securities Act and the Exchange Act) to the same extent as provided above with respect to the indemnification of the Holders, if requested in connection with any Registration Statement, any Prospectus, any Free Writing Prospectus or any Issuer Information.

(b)                                 Each Holder agrees, severally and not jointly, to indemnify and hold harmless the Company, the Initial Purchasers and the other selling Holders, the directors of the Company, each officer of the Company who signed the Registration Statement and each Person, if any, who controls the Company, any Initial Purchaser and any other selling Holder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages, liabilities or expenses that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Holder furnished to the Company in writing by such Holder expressly for use in any Registration Statement and any Prospectus.

(c)                                  Promptly after receipt by an indemnified party under this Section 5 of notice of the commencement of any action, such Person (the “Indemnified Person”) will, if a claim in respect thereof is to be made against such Indemnified Person under this Section 5, notify the Person against whom such indemnification may be sought (the “Indemnifying Person”) in writing of the commencement thereof; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under this Section 5 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under this Section 5.  If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person will be entitled to participate in and, to the extent that it shall elect, jointly with all other Indemnifying Persons similarly notified, by written notice delivered to the Indemnified Person promptly after receiving the aforesaid notice from such Indemnified Person, to assume the defense thereof with counsel reasonably satisfactory to such Indemnified Person; provided, however, if the defendants in any such action include both the Indemnified Person and the Indemnifying Person and the Indemnified Person shall have reasonably concluded that a conflict may arise between the positions of the Indemnifying Person and the Indemnified Person in conducting the defense of any such action or that there may be legal defenses available to it and/or other Indemnified Persons which are different from or additional to those available to the Indemnifying Person, the Indemnified Person or Persons shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such Indemnified Person or Persons.  Upon receipt of notice from the Indemnifying Person to such Indemnified Person of such Indemnifying Person’s election so to assume the defense of such action and approval by the Indemnified Person of counsel, the Indemnifying Person will not be liable to such Indemnified Person under this Section 5 for any legal or other expenses subsequently incurred by such Indemnified Person in connection with the defense thereof unless (i) the Indemnified Person

14

shall have employed separate counsel in accordance with the proviso to the immediately preceding sentence (it being understood, however, that the Indemnifying Person shall not be liable for the expenses of more than one separate counsel (together with local counsel (in each jurisdiction)), which shall be selected (A) by Wells Fargo Securities, LLC in the case of counsel representing the Initial Purchasers or their related persons), (B) by the Majority Holders in the case of any Holder, its directors and officers and any control Persons of such Holder representing the Indemnified Persons who are parties to such action), and (C) by the Company in all other cases; or (ii) the Indemnifying Person shall not have employed counsel satisfactory to the Indemnified Person to represent the Indemnified Person within a reasonable time after notice of commencement of the action, in each of which cases the fees and expenses of counsel shall be at the expense of the Indemnifying Person.  The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, which will not be unreasonably withheld, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss, claim, damage, liability or expense by reason of such settlement or judgment.  No Indemnifying Person shall, without the prior written consent of the Indemnified Person, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any Indemnified Person is or could have been a party and indemnification was or could have been sought hereunder by such Indemnified Person, unless such settlement (A) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such action, suit or proceeding and (B) does not include any statement as to or findings of fault, culpability or failure to act by or on behalf of any Indemnified Person.

(d)                                 If the indemnification provided for in paragraphs (a) and (b) above is for any reason held to be unavailable to or otherwise insufficient to hold harmless an Indemnified Person in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each Indemnifying Person under such paragraph, shall contribute to the aggregate amount paid or payable by such Indemnified Person, as incurred, as a result of any losses, claims, damages, liabilities or expenses referred to therein (i) in such proportion as is appropriate to reflect the relative benefits received by the Company from the offering of the Securities and the Exchange Securities, on the one hand, and by the Holders from receiving Securities or Exchange Securities registered under the Securities Act, on the other hand, or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company, on the one hand, and the Holders, on the other hand, in connection with the statements or omissions that resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations.  The relative fault of the Company, on the one hand, and the Holders, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Holders and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages, liabilities and expenses referred to in this paragraph (d) shall be deemed to include, subject to the limitations set forth above, any legal or other fees or expenses incurred by such Indemnified Person in connection with investigating or defending any such action or claim.

15

(e)                                  The Company and the Holders agree that it would not be just and equitable if contribution pursuant to this Section 5 were determined by pro rata allocation (even if the Holders were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above.  Notwithstanding the provisions of this Section 5, in no event shall a Holder be required to contribute any amount in excess of the amount by which the total price at which the Securities or Exchange Securities sold by such Holder exceeds the amount of any damages that such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.  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 5 are several and not joint.

(f)                                   The remedies provided for in this Section 5 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any Indemnified Person at law or in equity.

(g)                                  The indemnity and contribution provisions contained in this Section 5 shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of the Initial Purchasers or any Holder or any Person controlling any Initial Purchaser or any Holder, or by or on behalf of the Company or the officers or directors of or any Person controlling the Company, (iii) acceptance of any of the Exchange Securities and (iv) any sale of Registrable Securities pursuant to a Shelf Registration Statement.

6.                                      General.

(a)                                 No Inconsistent Agreements.  The Company represents, warrants and agrees that (i) the rights granted to the Holders hereunder do not in any way conflict with and are not inconsistent with the rights granted to the holders of any other outstanding securities issued or guaranteed by the Company under any other agreement and (ii) the Company has not entered into, or on or after the date of this Agreement will enter into, any agreement that is inconsistent with the rights granted to the Holders of Registrable Securities in this Agreement or otherwise conflicts with the provisions hereof.

(b)                                 Amendments and Waivers.  The provisions of this Agreement, including the provisions of this sentence, may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given unless the Company has obtained the written consent of Holders of at least a majority in aggregate principal amount of the outstanding Registrable Securities affected by such amendment, modification, supplement, waiver or consent; provided that no amendment, modification, supplement, waiver or consent to any departure from the provisions of Section 5 hereof shall be effective as against any Holder of Registrable Securities unless consented to in writing by such Holder.  Any amendments, modifications, supplements, waivers or consents pursuant to this Section 6(b) shall be by a writing executed by each of the parties hereto.

(c)                                  Notices.  All notices and other communications provided for or permitted hereunder shall be made in writing by hand-delivery, registered first-class mail, telex, telecopier,

16

or any courier guaranteeing overnight delivery (i) if to a Holder, at the most current address given by such Holder to the Company by means of a notice given in accordance with the provisions of this Section 6(c), which address initially is, with respect to the Initial Purchasers, the address set forth in the Purchase Agreement; (ii) if to the Company, initially at the Company’s address set forth in the Purchase Agreement and thereafter at such other address, notice of which is given in accordance with the provisions of this Section 6(c); and (iii) to such other persons at their respective addresses as provided in the Purchase Agreement and thereafter at such other address, notice of which is given in accordance with the provisions of this Section 6(c).  All such notices and communications shall be deemed to have been duly given: at the time delivered by hand, if personally delivered; five Business Days after being deposited in the mail, postage prepaid, if mailed; when receipt is acknowledged, if telecopied; and on the next Business Day if timely delivered to an air courier guaranteeing overnight delivery.  Copies of all such notices, demands or other communications shall be concurrently delivered by the Person giving the same to the Trustee, at the address specified in the Indenture.

(d)                                 Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors, assigns and transferees of each of the parties, including, without limitation and without the need for an express assignment, subsequent Holders; provided that nothing herein shall be deemed to permit any assignment, transfer or other disposition of Registrable Securities in violation of the terms of the Purchase Agreement or the Indenture.  If any transferee of any Holder shall acquire Registrable Securities in any manner, whether by operation of law or otherwise, such Registrable Securities shall be held subject to all the terms of this Agreement, and by taking and holding such Registrable Securities such Person shall be conclusively deemed to have agreed to be bound by and to perform all of the terms and provisions of this Agreement and such Person shall be entitled to receive the benefits hereof.  The Initial Purchasers (in their capacity as Initial Purchasers) shall have no liability or obligation to the Company with respect to any failure by a Holder to comply with, or any breach by any Holder of, any of the obligations of such Holder under this Agreement.

(e)                                  Third Party Beneficiaries.  Each Holder shall be a third party beneficiary to the agreements made hereunder between the Company, on the one hand, and the Initial Purchasers, on the other hand, and shall have the right to enforce such agreements directly to the extent it deems such enforcement necessary or advisable to protect its rights or the rights of other Holders hereunder.

(f)                                   Counterparts. This Agreement may be executed in any number of counterparts and by the parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement.

(g)                                  Headings.  The headings in this Agreement are for convenience of reference only, are not a part of this Agreement and shall not limit or otherwise affect the meaning hereof.

(h)                                 Governing Law.  This Agreement and any claim, controversy or dispute arising under or related to this Agreement shall be governed by and construed in accordance with the laws of the State of New York.

17

(i)                                     Entire Agreement; Severability.  This Agreement contains the entire agreement between the parties relating to the subject matter hereof and supersedes all oral statements and prior writings with respect thereto.  If any term, provision, covenant or restriction contained in this Agreement is held by a court of competent jurisdiction to be invalid, void or unenforceable or against public policy, the remainder of the terms, provisions, covenants and restrictions contained herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated.  The Company and the Initial Purchasers shall endeavor in good faith negotiations to replace the invalid, void or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, void or unenforceable provisions.
