Section 2. Exchange Offer

(a) Unless the Exchange Offer would violate applicable law, public policy or interpretation of the staff of the Commission, the Issuers shall (i) file a Registration Statement (the “Exchange Offer Registration Statement”) with the Commission on Form S-4 or another appropriate Securities Act registration form with respect to a registered offer (the “Exchange Offer”) to exchange any and all of the Registrable Notes for a like aggregate principal amount of notes (including the guarantees with respect thereto, the “Exchange Notes”) that are identical in all material respects to the Notes (except that the Exchange Notes shall not contain restrictive legends, terms with respect to transfer restrictions or Additional Interest upon a Registration Default), (ii) use their reasonable best efforts to cause the Exchange Offer Registration Statement to be declared effective under the Securities Act within 180 days after the date of this Agreement and (iii) use their reasonable best efforts to consummate the Exchange Offer within 240 days after the date of this Agreement. Upon the Exchange Offer Registration Statement being declared effective by the Commission, the Issuers will offer the Exchange Notes in exchange for surrender of the Notes. The Issuers shall keep the Exchange Offer open for not less than 20 business days (or longer if required by applicable law, including, without limitation, Regulation 14E under the Exchange Act) after the date notice of the Exchange Offer is first mailed, sent or given to Holders.

Each Holder that participates in the Exchange Offer will be required to represent to the Issuers in writing that (i) any Exchange Notes to be received by it will be acquired in the ordinary course of its business, (ii) it has no arrangement or understanding with any Person to participate in the public distribution (within the meaning of the Securities Act) of the Exchange Notes in violation of the provisions of the Securities Act, (iii) it is not an “affiliate” as defined by Rule 405 of the Securities Act of any of the Issuers, or if it is an affiliate, it will comply with the registration and prospectus delivery requirements of the Securities Act to the extent applicable, (iv) if such Holder is not a broker-dealer, it is not engaged in, and does not intend to engage in, a public distribution of the Exchange Notes and (v) if such Holder is a broker-dealer that will receive Exchange Notes for its own account in exchange for Notes that were acquired as a result of market-making or other trading activities, it will deliver a prospectus in connection with any resale of such Exchange Notes.

(b) The Issuers and the Initial Purchasers acknowledge that the staff of the Commission has taken the position that any broker-dealer that elects to exchange Notes that were acquired by such broker-dealer for its own account as a result of market-making or other trading activities for Exchange Notes in the Exchange Offer (a “Participating Broker-Dealer”) may be deemed to be an “underwriter” within the meaning of the Securities Act and must deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of such Exchange Notes.

The Issuers and the Initial Purchasers also acknowledge that the staff of the Commission has taken the position that if the Prospectus contained in the Exchange Offer Registration Statement includes a plan of distribution containing a statement to the effect set forth in the immediately preceding paragraph and the means by which Participating Broker-Dealers may resell the Exchange Notes, without naming the Participating Broker-Dealers or specifying the amount of Exchange Notes owned by them, such Prospectus may be delivered by Participating Broker-Dealers to satisfy their prospectus delivery obligations under the Securities Act in connection with resales of Exchange Notes for their own accounts, so long as the Prospectus otherwise meets the requirements of the Securities Act.

In light of the foregoing, if requested by a Participating Broker-Dealer (a “Requesting Participating Broker-Dealer”), the Issuers agree to use their reasonable best efforts to keep the Exchange Offer Registration Statement continuously effective for a period necessary to comply with applicable law in connection with such resales but in no event more than 180 days after the date on which the Exchange Registration Statement is declared effective, or such longer period if extended pursuant to any Delay Period in accordance with the last paragraph of Section 5 hereof, or such earlier date as each Requesting Participating Broker-Dealer shall have notified the Company in writing that such Requesting Participating Broker-Dealer has resold all Exchange Notes acquired by it in the Exchange Offer (such period, the “Applicable Period”). The Issuers shall include a plan of distribution in such Exchange Offer Registration Statement that meets the requirements set forth in the preceding paragraph.

If, prior to consummation of the Exchange Offer, any Initial Purchaser or any other Holder holds any Notes acquired by it is not entitled to participate in the Exchange Offer, the Issuers upon the request of the Initial Purchasers or any such Holder, as the case may be, shall simultaneously with the delivery of the Exchange Notes in the Exchange Offer, issue and deliver to the Initial Purchasers or any such Holder, as the case may be, in exchange (the “Private Exchange”) for such Notes held by such Initial Purchaser or any such Holder a like principal amount of notes (the “Private Exchange Notes”) of the Issuers that are identical in all material respects to the Exchange Notes except that the Private Exchange Notes may be subject to restrictions on transfer and bear a legend to such effect. The

Private Exchange Notes shall be issued pursuant to the same indenture as the Exchange Notes and bear the same CUSIP number as the Exchange Notes (if permitted by the CUSIP Service Bureau),

Upon consummation of the Exchange Offer in accordance with this Section 2, the Issuers shall have no further registration obligations other than the Issuers’ continuing registration obligations with respect to (i) Private Exchange Notes, (ii) Exchange Notes held by Participating Broker-Dealers and (iii) Notes or Exchange Notes as to which clause (c)(iv) of this Section 2 applies.

In connection with the Exchange Offer, the Issuers shall:

(1) mail or cause to be mailed to each Holder through the depositary for the Notes or otherwise entitled to participate in the Exchange Offer a copy of the Prospectus forming part of the Exchange Offer Registration Statement, together with an appropriate letter of transmittal and related documents;

(2) utilize the services of a depositary for the Exchange Offer with an address in the Borough of Manhattan, The City of New York;

(3) permit Holders to withdraw tendered Notes at any time prior to the close of business, New York time, on the last Business Day on which the Exchange Offer shall remain open; and

(4) otherwise comply in all material respects with all applicable laws, rules and regulations (including, without limitation, Regulation 14E under the Exchange Act).

As soon as practicable after the close of the Exchange Offer and the Private Exchange, if any, the Issuers shall:

(1) accept for exchange all Notes validly tendered and not validly withdrawn by the Holders pursuant to the Exchange Offer and the Private Exchange, if any;

(2) deliver or cause to be delivered to the Trustee for cancellation all Registrable Notes so accepted for exchange; and

(3) cause the Trustee to authenticate and deliver promptly to each such Holder of Notes, Exchange Notes or Private Exchange Notes, as the case may be, equal in principal amount to the Registrable Notes of such Holder so accepted for exchange.

The Exchange Offer and the Private Exchange shall not be subject to any conditions, other than that (i) the Exchange Offer or Private Exchange, as the case may be, does not violate applicable law or any applicable interpretation of the staff of the Commission, (ii) no action or proceeding shall have been instituted or threatened in any court or by any governmental agency which might materially impair the ability of the Issuers to proceed with the Exchange Offer or the Private Exchange, and no material adverse development shall have occurred in any existing action or proceeding with respect to the Issuers and (iii) all governmental approvals shall have been obtained, which approvals the Company deems necessary for the consummation of the Exchange Offer or Private Exchange.

The Exchange Notes and the Private Exchange Notes shall be issued under (i) the Indenture or (ii) an indenture identical in all material respects to the Indenture (in either case, with such changes as are necessary to comply with any requirements of the Commission to effect or maintain the

qualification thereof under the TIA) and which, in either case, has been qualified under the TIA and shall provide that (a) the Exchange Notes shall not be subject to the transfer restrictions set forth in the Indenture and.(b) the Private Exchange Notes shall be subject to the transfer restrictions set forth in the Indenture. The Indenture or such indenture shall provide that the Exchange Notes, the Private Exchange Notes and the Notes shall vote and consent together on all matters as one class and that none of the Exchange Notes, the Private Exchange Notes or the Notes will have the right to vote or consent as a separate class on any matter.

(c) In the event that (i) any changes in law, public policy or the applicable interpretations of the staff of the Commission do not permit the Issuers to effect the Exchange Offer, (ii) for any reason the Exchange Offer is not consummated within 240 days of the date of this Agreement, (iii) any Holder notifies the Company prior to the 30th day following consummation of the Exchange Offer that it is prohibited by law or the applicable interpretations of the staff of the Commission from participating in the Exchange Offer or (iv) in the case of any Holder who participates in the Exchange Offer, such Holder does not receive Exchange Notes on the date of the exchange that may be sold without restriction under state and federal securities laws (other than due solely to the status of such Holder as an affiliate of any Issuer within the meaning of the Securities Act and provided that such Holder provides the Company with notice of such event prior to the 90th day following the date of the exchange date) (each such event referred to in clauses (i) through (iv) of this sentence, a “Shelf Filing Event”), then the Issuers shall file a Shelf Registration Statement pursuant to Section 3 hereof.

(d) Each of the Issuers represents, warrants and covenants that it will not, and will use its reasonable best efforts to cause its agents and representatives not to prepare, make, use, authorize, approve or refer to any Free Writing Prospectus in connection with any Exchange Offer.

Section 3. Shelf Registration Statement

If at any time a Shelf Filing Event shall occur, then:

(a) Shelf Registration Statement. The Issuers shall file with the Commission a Registration Statement for an offering to be made on a continuous basis pursuant to Rule 415 covering all of the Registrable Notes not exchanged in the Exchange Offer, Private Exchange Notes and Exchange Notes as to which Section 2(c)(iv) is applicable (the “Shelf Registration Statement”). The Shelf Registration Statement shall be on Form S-I or another appropriate form permitting registration of such Registrable Notes for resale by Holders in the manner or manners designated by them (including, without limitation, one or more underwritten offerings). The Issuers shall not permit any securities other than the Registrable Notes to be included in the Shelf Registration Statement.

(b) The Issuers shall use all their reasonable best efforts (x) to cause the Shelf Registration Statement to be declared effective under the Securities Act on or prior to the later of (A) the 240th day after the date of this Agreement and (B) the 120th day after the occurrence of the applicable Shelf Filing Event and (y) to keep the Shelf Registration Statement continuously effective under the Securities Act for the period ending on the date which is two years from the date of this Agreement, subject to extension pursuant to the penultimate paragraph of Section 5 hereof (the “Effectiveness Period”), or such shorter period ending when all Registrable Notes covered by the Shelf Registration Statement have been sold in the manner set forth and as contemplated in the Shelf Registration Statement; provided, however, that (i) the Effectiveness Period in respect of the Shelf Registration Statement shall be extended to the extent required to permit dealers to comply with the applicable prospectus delivery requirements of Rule 174 under

the Securities Act and as otherwise provided herein and (ii) the Company may suspend the effectiveness of the Shelf Registration Statement by written notice to the Holders solely (A) as a result of the filing of a post-effective amendment to the Shelf Registration Statement to incorporate annual audited financial information with respect to the Company where such post-effective amendment is not yet effective and needs to be declared effective to permit Holders to use the related Prospectus or (B) to the extent and for so long as permitted by the penultimate paragraph of Section 5.

(c) Supplements and Amendments. The Issuers agree to supplement or make amendments to the Shelf Registration Statement as and when required by the rules, regulations or instructions applicable to the registration form used for such Shelf Registration Statement or by the Securities Act or rules and regulations thereunder for shelf registration, or if reasonably requested by the Majority Holders or by any underwriter of the Registrable Notes covered by such Registration Statement.

Section 4. Additional Interest

(a) The Issuers and the Initial Purchasers agree that the Holders will suffer damages if the Issuers fail to fulfill their obligations under Section 2 or Section 3 hereof and that it would not be possible to ascertain the extent of such damages with precision. Accordingly, the Issuers agree that if:

(i) the Exchange Offer is not consummated on or prior to the 240th day following the date of this Agreement, or, if that day is not a Business Day, the next day that is a Business Day; or

(ii) the Shelf Registration Statement is required to be filed but is not declared effective by the Commission within the time period specified in Section 3(b)(x), or is declared effective by such date but thereafter ceases to be effective or usable (unless the Shelf Registration Statement ceases to be effective or usable as specifically permitted by the penultimate paragraph of Section S hereof),

(each such event referred to in clauses (i) and (ii) a “Registration Default”), additional cash interest (“Additional Interest”) will accrue on the affected Registrable Notes until the Exchange Offer is consummated or a Shelf Registration Statement is declared effective by the SEC or the date on which such Registrable Note ceases to be a Registrable Note or otherwise becomes freely transferable by Holders other than affiliates of the Issuers without further registration under the Securities Act. The rate of Additional Interest will be 0.25% per annum for the first 90-day period immediately following the occurrence of a Registration Default, increasing by an additional 0.25% per annum with respect to each subsequent 90-day period up to a maximum amount of Additional Interest of 1.00% per annum, from and including the date on which any such Registration Default shall occur to, but excluding, the earlier of (1) the date on which all Registration Defaults have been cured or (2) the date on which such Registrable Note ceases to be a Registrable Note or otherwise becomes freely transferable by Holders other than affiliates of the Issuers without further registration under the Securities Act. If, after the cure of all Registration Defaults then in effect, there is a subsequent Registration Default, the rate of Additional Interest for such subsequent Registration Default shall initially be 0.25% regardless of the rate in effect

with respect to any prior Registration Default at the time of cure of such Registration Default and shall increase in the manner and be subject to the maximum Additional Interest rate contained in the preceding sentence.

Notwithstanding the foregoing, (1) the amount of Additional Interest payable shall not increase because more than one Registration Default has occurred and is pending and (2) a Holder of Registrable Notes that is not entitled to the benefits of the Shelf Registration Statement (e.g., such Holder has not elected to include information) shall not be entitled to Additional Interest with respect to a Registration Default that pertains to the Shelf Registration Statement.

(b) So long as Notes remain outstanding, the Company shall notify the Trustee within five Business Days after a Registration Default occurs. Any amounts of Additional Interest due pursuant to clauses (a)(i) or (a)(ii) of this Section 4 will be payable in cash semi-annually on each April 15 and October 15 (each a “Additional Interest Payment Date”), commencing with the first such date occurring after any such Additional Interest commences to accrue, to Holders to whom regular interest is payable on such Additional Interest Payment Date with respect to Notes that are Registrable Notes. For all purposes of this Section 4, the amount of Additional Interest for each Registrable Note will be determined by multiplying the applicable rate of Additional Interest by the aggregate principal amount of such Registrable Note outstanding on the Additional Interest Payment Date following such Registration Default in the case of the first such payment of Additional Interest with respect to a Registration Default (and thereafter at the next succeeding Additional Interest Payment Date until the cure of such Registration Default), and multiplying the product of the foregoing by a fraction, the numerator of which is the number of days such Additional Interest rate was applicable during such period (determined on the basis of a 360-day year comprised of twelve 30-day months and, in the case of a partial month, the actual number of days elapsed), and the denominator of which is 360.

Section 5. Registration Procedures

In connection with the filing of any Registration Statement pursuant to Section 2 or 3 hereof, the Issuers shall effect such registrations to permit the sale of the securities covered thereby in accordance with the intended method or methods of disposition thereof, and pursuant thereto and in connection with any Registration Statement filed by the Issuers hereunder, the Issuers shall:

(a) Prepare and file with the Commission the Registration Statement or Registration Statements prescribed by Section 2 or 3 hereof, and use their reasonable best efforts to cause each such Registration Statement to become effective and remain effective as provided herein; provided, however, that, if (1) such filing is pursuant to Section 3 hereof, or (2) a Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during the Applicable Period relating thereto, before filing any Registration Statement or Prospectus or any amendments or supplements thereto, the Issuers shall furnish to and afford the Holders of the Registrable Notes covered by such Registration Statement or each such Participating Broker-Dealer, as the case may be, their counsel (if requested by any such person) and the managing underwriters, if any, a reasonable opportunity to review copies of all such documents (including copies of any documents to be incorporated-by reference therein and all exhibits thereto) proposed to be filed (in each case at least five Business Days prior to such filing).

made, not misleading, and (vi) of the Company’s determination that a post-effective amendment to a Registration Statement is required.

(d) If (1) a Shelf Registration Statement is filed pursuant to Section 3 hereof, or (2) a Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during the Applicable Period, if threatened by the Commission or state securities authority, use their reasonable best efforts to prevent the issuance of any order suspending the effectiveness of a Registration Statement or of any order preventing or suspending the use of a Prospectus or suspending the qualification (or exemption from qualification) of any of the Registrable Notes or the Exchange Notes, as the case may be, for sale in any jurisdiction, and, if any such order is issued, to use their reasonable best efforts to obtain the withdrawal of any such order at the earliest practicable moment.

(n) If (1) a Shelf Registration Statement is filed pursuant to Section 3 hereof or (2) a Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during the Applicable Period, make available for inspection by a representative acceptable to the Majority Holders or each such Participating Broker-Dealer, as the case may be, any underwriter participating in any such disposition of Registrable Notes, if any, and any attorney, accountant or other agent retained by the Majority Holders or each such Participating Broker-Dealer, as the case may be, or underwriter (collectively, the “Inspectors”), at the offices where normally kept, during reasonable business hours and upon reasonable notice, all financial and other records, pertinent corporate documents and instruments of the Company and its subsidiaries (collectively, the “Records”) as shall be reasonably necessary to enable them, to exercise any applicable due diligence responsibilities, and cause the officers, directors and employees of the Company and its subsidiaries to supply all information reasonably requested by any such Inspector in connection with such Registration Statement and Prospectus.

(o) Provide an indenture trustee for the Registrable Notes or the Exchange Notes, as the case may be, and cause the Indenture or the trust indenture provided for in Section 2(a) hereof to be qualified under the TIA not later than the effective date of the Exchange Offer or the first Registration Statement relating to the Registrable Notes; and in connection therewith, cooperate with the trustee under any such indenture and the Holders of the Registrable Notes or Exchange

Notes, as applicable, to effect such changes to such indenture as may be required for such indenture to be so qualified in accordance with the terms of the TIA; and execute, and use their reasonable best efforts to cause such trustee to execute, all documents as may be required to effect such changes, and all other forms and documents required to be fled with the Commission to enable such indenture to be so qualified in a timely manner.

(p) Comply with all applicable rules and regulations of the Commission and make generally available to the Company’s securityholders earnings statements satisfying the provisions of Section 11 (a) of the Securities Act and Rule 158 thereunder (or any similar rule promulgated under the Securities Act) no later than 45 days after the end of any 12-month period (or 90 days after the end of any 12-month period if such period is a fiscal year) (i) commencing at the end of any fiscal quarter in which Registrable Notes or Exchange Notes are sold to underwriters in a firm commitment or best efforts underwritten offering and (ii) if not sold to underwriters in such an offering, commencing on the first day of the first fiscal quarter of the Company after the effective date of a Registration Statement, which statements shall cover said 12-month periods consistent with the requirements of Rule 158.

(q) Upon the request of a Holder, upon consummation of the Exchange Offer or a Private Exchange, use their reasonable best efforts to obtain an opinion of counsel to the Issuers, in a form customary for underwritten transactions, addressed to the Trustee for the benefit of all Holders of Registrable Notes participating in the Exchange Offer or the Private Exchange, as the case may be, that the Exchange Notes or Private Exchange Notes, as the case may be, and the related indenture constitute legal, valid and binding obligations of the Issuers, enforceable against the Issuers in accordance with its respective terms, subject to customary exceptions and qualifications.

(r) If the Exchange Offer or a Private Exchange is to be consummated, upon delivery of the Registrable Notes by Holders to the Company (or to such other Person as directed by the Company) in exchange for the Exchange Notes or the Private Exchange Notes, as the case may be, ▇▇▇▇, or cause to be marked, on such Registrable Notes that such Registrable Notes are being cancelled in exchange for the Exchange Notes or the Private Exchange Notes, as the case may be; provided that in no event shall such Registrable Notes be marked as paid or the obligations of the Issuers thereunder otherwise satisfied.

(s) Cooperate with each seller of Registrable Notes covered by any Registration Statement and each underwriter, if any, participating in the disposition of such Registrable Notes and their respective counsel in connection with any filings required to be made with the Financial Industry Regulatory Authority (“FINRA”).

(t) Use their reasonable best efforts to take all other steps reasonably necessary or advisable to effect the registration of the Exchange Notes and/or Registrable Notes covered by a Registration Statement contemplated hereby.

The Company may require each seller of Registrable Notes or Exchange Notes as to which any registration is being effected to furnish to the Company such information regarding such seller and the proposed distribution by such Holder of such Registrable Notes or Exchange Notes as the Company may, from time to time, reasonably request. The Company may exclude from such registration the Registrable Notes of any Holder so long as such Holder fails to furnish such information within a reasonable time after receiving such request and in the event of such an exclusion, the Issuers shall have

no further obligation under this Agreement (including, without limitation, the obligations under Section 4) with respect to such Holder or any subsequent Holder of such Registrable Notes. Each Holder as to which any Shelf Registration Statement is being effected agrees to furnish promptly to the Company all information required to be disclosed in order to make any information previously furnished to the Company by such Holder not materially misleading.

If any such Registration Statement refers to any Holder by name or otherwise as^: the holder or beneficial owner of any securities of the Company or the Guarantors, then such Holder shall have the right to require (i) the insertion therein of language, in form and substance reasonably satisfactory to such Holder, to the effect that the holding by such Holder of such securities is not to be construed as a recommendation by such Holder of the investment quality of the securities covered thereby and that such holding does not imply that such Holder will assist in meeting any future financial requirements of the Company or the Guarantors, or (ii) in the event that such reference to such Holder by name or otherwise is not required by the Securities Act or any similar federal statute then in force, the deletion of the reference to such Holder in any amendment or supplement to the applicable Registration Statement filed or prepared subsequent to the time that such reference ceases to be required.

Each Holder of Registrable Notes and each Participating Broker-Dealer agrees by acquisition of such Registrable Notes or Exchange Notes that, upon the Company providing notice to such Holder or Participating Broker-Dealer, as the case may be, (x) of the happening of any event of the kind described in Section 5(c)(ii), 5(c)(iii), 5(c)(iv), or 5(c)(v) hereof, or (y) that the Board of Directors of the Company (the “Board of Directors”) has resolved that the Company has a bona fide business purpose, or after consultation with legal counsel, has determined in good faith that there is a reason as a matter of law, for doing so, then, upon providing such notice (which shall refer to this penultimate paragraph of this Section 5), the Issuers may delay the filing or the effectiveness of the Exchange Offer Registration Statement or the Shelf Registration Statement (if not then filed or effective, as applicable) and shall not be required to maintain the effectiveness thereof or amend or supplement the Exchange Offer Registration Statement or the Shelf Registration Statement, in all cases, for a period (a “Delay Period”) expiring upon the earlier to occur of (i) in the case of the immediately preceding clause (x), such Holder’s or Participating Broker-Dealer’s receipt of the copies of the supplemented or amended Prospectus contemplated by Section 5(k) hereof or until it is advised in writing (the “Advice”) by the Company that the use of the applicable Prospectus may be resumed, and has received copies of any amendments or supplements thereto or (ii) in the case of the immediately preceding clause (y), the date which is the earlier of (A) the date on which such business purpose ceases to interfere with the Issuers’ obligations to file or maintain the effectiveness of any such Registration Statement pursuant to this Agreement or (B) 75 days after the Company notifies the Holders of such good faith determination. There shall not be more than 75 days of Delay Periods during any 12-month period. The maximum length of the Applicable Period set forth in Section 2(b) shall be extended by a number of days equal to the number of days during any Delay Period. Any Delay Period will not alter the obligations of the Issuers to pay Additional Interest under the circumstances set forth in Section 4 hereof.

Each Holder or Participating Broker-Dealer, by its acceptance of any Registrable Note; agrees that during any Delay Period, each Holder or Participating Broker-Dealer will immediately discontinue disposition of such Notes or Exchange Notes covered by such, Registration Statement or Prospectus or Exchange Notes to be sold by such Holder or Participating Broker-Dealer, as the case may be.

Section 6. Registration Expenses

All fees and expenses incident to the performance of or compliance with this Agreement by the Issuers (other than any underwriting discounts or commissions) shall be borne by the Issuers, whether or not the Exchange Offer Registration Statement or the Shelf Registration Statement is filed or becomes effective or the Exchange Offer is consummated, including, without limitation, (i) all registration and filing fees (including, without limitation, fees and expenses of compliance with state securities or Blue Sky laws (including, without limitation, the reasonable fees and disbursements of counsel in connection with Blue Sky qualifications of the Registrable Notes or Exchange Notes and determination of the eligibility of the Registrable Notes or Exchange Notes for investment under the laws of such jurisdictions (x) where the holders of Registrable Notes are located, in the case of an Exchange Offer, or (y) as provided in Section 5(h) hereof, in the case of a Shelf Registration Statement or in the case of Exchange Notes to be sold by a Participating Broker-Dealer during the Applicable Period)), (ii) printing expenses, including, without limitation, expenses of printing certificates for Registrable Notes or Exchange Notes in a form eligible for deposit with The Depository Trust Company and of printing prospectuses if the printing of prospectuses is requested by the managing underwriter or underwriters, if any, or by the Majority Holders or in respect of Exchange Notes to be sold by Participating Broker-Dealer during the Applicable Period, as the case may be, (iii) messenger, telephone and delivery expenses of the Company, (iv) fees and disbursements of counsel for the Issuers and the reasonable fees and disbursements of one special counsel for all of the sellers of Registrable Notes (exclusive of any counsel retained pursuant to Section 7 hereof) selected by the Majority Holders and reasonably satisfactory to the Issuers, (v) fees and disbursements of all independent certified public accountants referred to in Section 5(m)(iii) hereof (including, without limitation, the expenses of any special audit and “cold comfort” letters required by or incident to such performance), (vi) directors’ and officers’ liability insurance, (vii) fees and expenses of all other Persons retained by any of the Issuers, (viii) internal expenses of the Issuers (including, without limitation, all salaries and expenses of officers and employees of the Company performing legal or accounting duties), (ix) the expense of any annual audit, (x) the fees and expenses incurred in connection with the listing of the securities to be registered on any securities exchange, and the obtaining of a rating of the securities, in each case, if applicable, (xi) any required fees and expenses incurred in connection with any filing required to be made with FINRA and (xii) the expenses relating to printing, word processing and distributing all Registration Statements, underwriting agreements, indentures and any other documents necessary in order to comply with this Agreement. Notwithstanding the foregoing or anything to the contrary, each Holder shall pay all underwriting discounts and commissions of any underwriters with respect to any Registrable Notes sold by or on behalf of it.

Section 7. Indemnification

(a) The Issuers agree jointly and severally to indemnify and bold harmless (i) the Initial Purchasers, each Holder and each Person, if any, who controls any Initial Purchaser or any Holder within the meaning of either Section 15 of the 1933 Act or Section 20 of the 1934 Act, or is under common control with, or is controlled by, any Initial Purchaser or any Holder, from and against all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred by any Initial Purchaser or any Holder or any such controlling or affiliated Person in connection with defending or investigating any such action or claim) upon presentation of a statement or statements therefore in reasonable detail, caused by untrue statement or alleged untrue statement of a material fact contained in any Registration Statement (or any amendment thereto) pursuant to which Exchange Notes or Registrable Notes were registered under the 1933 Act, including all documents incorporated therein by reference, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or caused by any untrue statement or alleged untrue statement of a material fact contained in any Prospectus (as amended or supplemented if the Issuers shall have furnished any amendments or supplements thereto), or any

preliminary prospectus, or any Free Writing Prospectus used in violation of this Agreement or any “Issuer Information” filed or required to be filed pursuant to Rule 433(d) under the 1933 Act, or caused by any omission or alleged omission to state therein a material fact necessary to make the statements therein in the light of the circumstances under which they were made not misleading, except insofar as such losses, claims, damages or liabilities are caused by such untrue statement or omission or alleged untrue statement or omission based upon information relating to the Initial Purchasers or any Holder furnished to the Company in writing by the Initial Purchasers or any selling Holder, as applicable, expressly for use therein.

(b) Each Holder agrees, severally and not jointly, to indemnify and hold harmless the Issuers, the Initial Purchasers and the other selling Holders, and each of their respective directors, officers who sign the Registration Statement and each Person, if any, who controls any Issuer, any Initial Purchaser and any other selling Holder within the meaning of either Section 15 of the 1933 Act or Section 20 of the 1934 Act to the same extent as the foregoing indemnity from the Issuers to the Initial Purchasers and the Holders, but only with respect to information relating to such Holder furnished to the Company in writing by such Holder expressly for use in any Registration Statement (or any amendment thereto) or any Prospectus (or any amendment or supplement thereto) or any preliminary prospectus, or any Free Writing Prospectus used in violation of this Agreement filed or required to be filed pursuant to Rule 433(d) under the 1933 Act.

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any Person in respect of which indemnity may be sought pursuant to paragraph (a) or (b) above, such Person (the “indemnified party”) shall promptly notify the Person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the reasonable fees and disbursements of such counsel related to such proceeding; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability that it may have under this Section 7 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential conflicts of interests between them. It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (a) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Initial Purchasers and all Persons, if any, who control any Initial Purchaser within the meaning of either Section 15 of the 1933 Act or ▇▇▇▇▇▇▇ ▇▇ ▇▇ ▇▇▇ ▇▇▇▇ ▇▇▇, (▇) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Issuers, their respective directors and officers who sign the Registration Statement and each Person, if any, who controls the Company or the Guarantors within the meaning of either such Section 15 of the 1933 Act or Section 20 of the 1934 Art and (c) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Holders and all Persons, if any, who control any Holders within the meaning of either such Section, and that all such fees and expenses shall be reimbursed as they are incurred. In such case involving the Initial Purchasers and Persons who control the Initial Purchasers, such firm shall be designated in writing by Deutsche Bank Securities Inc. In such case involving the Holders and such Persons who control the Holders, such firm shall be designated in writing by the Majority Holders. In all other cases, such firm shall be designated by the Company. The indemnifying

party shall not be liable for any settlement of any proceeding effected without its written consent but, if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which such indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and does not include any fording of fault, culpability or failure to act by or behalf of any indemnified party.

(d) If the indemnification provided for in paragraph (a) or (b) of this Section 7 is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities iii such proportion as is appropriate to reflect the relative benefits received by the Issuers, on the one hand, and the Holders on the other hand, from the offering of Registrable Notes or Exchange Notes or, if the allocation provided for in paragraph (a) and (b) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in this clause 7(d) but also the relative fault of the Issuers on the one hand and of the Holders on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative fault of the Issuers, on the one hand, and the Holders on the other hand, shall be determined by reference to, among other things, whether the 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 Issuers or by the Holders and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Holders’ respective obligations to contribute pursuant to this Section 7(d) are several in proportion to the respective principal amount of Registrable Notes of such Holder that were registered pursuant to a Registration Statement.

(e) The Issuers and each Holder agree that it would not be just or equitable if contribution pursuant to this Section 7 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 7, no Holder shall be required to indemnify or contribute any amount in excess of the amount by which the total price at which Registrable Notes were 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 ▇▇▇▇ ▇▇▇) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

The indemnity and contribution provisions contained in this Section 7 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, any Holder or any Person controlling any Initial Purchaser or any Holder, or by or on behalf of the Company, the Guarantors, their respective

officers or directors or any Person controlling the Company or the Guarantors, (iii) acceptance of any of the Exchange Notes and (iv) any sale of Registrable Notes pursuant to a Shelf Registration Statement.

Section 8. Rules 144 and 144A

The Issuers covenant that they will file the reports required, if any, to be filed by them under the Securities Act and the Exchange Act and the rules and regulations adopted by the Commission thereunder in a timely manner in accordance with the requirements of the Securities Act and the Exchange Act and, if at any time the Issuers are not required to file such reports, they will, upon the request of any Holder or beneficial owner of Registrable Notes, make available such information necessary to permit sales pursuant to Rule 144A under the Securities Act. The Issuers further covenant that for so long as any Registrable Notes remain outstanding they will take such further action as any Holder of Registrable Notes may reasonably request from time to time to enable such Holder to sell Registrable Notes without registration under the Securities Act within the limitation of the exemptions provided by (a) Rule 144(k) and Rule 144A under the Securities Act, as such Rules may be amended from time to time, or (b) any similar rule or regulation hereafter adopted by the Commission.

Section 9. Underwritten Registrations

If any of the Registrable Notes covered by any Shelf Registration Statement are to be sold in an underwritten offering, the investment banker or investment bankers and manager or managers that will manage the offering will be selected by the Majority Holders included in such offering and shall be reasonably acceptable to the Company.

No Holder of Registrable Notes may participate in any underwritten registration hereunder if such Holder does not (a) agree to sell such Holder’s Registrable Notes on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements and (b) complete and execute all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents required under the terms of such underwriting arrangements.

Section 10. Miscellaneous

(a) Remedies. The Issuers hereby agree that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by them of the provisions of this Agreement and hereby agree to waive the defense in any action for specific performance that a remedy at law would be adequate.

(b) No Inconsistent Agreements. The Issuers have not, as of the date hereof, and shall not, after the date of this Agreement, enter into any agreement with respect to any of their securities that is inconsistent with the rights granted to the Holders of Registrable Notes in this Agreement or otherwise conflicts with the provisions hereof. The rights granted to the Holders hereunder do not conflict with and are not inconsistent with, in any material respect, the rights granted to the holders of any of the Issuers’ other issued and outstanding securities under any such agreements. The Issuers have not entered and will not enter into any agreement with respect to any of their securities which will grant to any Person piggy-back registration rights with respect to any Registration Statement.

(c) Adjustments Affecting Registrable Notes. The Issuers shall not, directly or indirectly, take any action with respect to the Registrable Notes as a class that would adversely affect the
