SECTION 3. Registered Exchange Offer.

(a) Unless the Exchange Offer shall not be permissible under applicable law or Commission policy (after the procedures set forth in Section 6(a) hereof have been complied with), the Company and the Guarantors shall (i) use their commercially reasonable efforts to cause to be filed with the Commission after the Closing Date, a Registration Statement under the Securities Act relating to the Exchange Notes and the Exchange Offer, (ii) use their commercially reasonable efforts to cause such Registration Statement to become effective not later than 270 days after the Closing Date, (iii) in connection with the foregoing, file (A) all pre-effective amendments to such Registration Statement as may be necessary in order to cause such Registration Statement to become effective, (B) if applicable, a post-effective amendment to such Registration Statement pursuant to Rule 430A under the Securities Act and (C) cause all necessary filings in connection with the registration and qualification of the Exchange Notes to be made under the state securities or blue sky laws of such jurisdictions as are necessary to permit Consummation of the Exchange Offer, and (iv) upon the effectiveness of such Registration Statement, commence the Exchange Offer. The Exchange Offer shall be on the appropriate form permitting (i) registration of the offer and issuance of the Exchange Notes to be offered in exchange for the Initial Notes that are Transfer Restricted Securities and (ii) resales of Exchange Notes by Broker Dealers who currently hold Transfer Restricted Securities and that were acquired for their own account as a result of market making activities or other trading

activities (other than Initial Notes acquired directly from the Company or any of its Affiliates) as contemplated by Section 3(c) below.

(b) The Company and the Guarantors shall use their commercially reasonable efforts to cause the Exchange Offer Registration Statement to be effective continuously and shall keep the Exchange Offer open for a period of not less than the minimum period required under applicable federal and state securities laws to Consummate the Exchange Offer; provided, however, that in no event shall such period be less than 30 days after the date notice of the Exchange Offer is mailed to the Holders. The Company and the Guarantors shall cause the Exchange Offer to comply with all applicable federal and state securities laws. No securities other than the Exchange Notes and the related Guarantees shall be included in the Exchange Offer Registration Statement. The Company and the Guarantors shall use their commercially reasonable efforts to cause the Exchange Offer to be Consummated no later than 30 Business Days after the date the Exchange Offer Registration Statement has become effective , or such later date as may be required by United States federal securities laws.

(c) The Company shall indicate in a “Plan of Distribution” section contained in the Prospectus forming a part of the Exchange Offer Registration Statement that any Broker-Dealer who holds Transfer Restricted Securities and that were acquired for its own account as a result of market-making activities or other trading activities (other than Transfer Restricted Securities acquired directly from the Company), may exchange such Initial Notes pursuant to the Exchange Offer; however, such Broker-Dealer may be deemed to be an “underwriter” within the meaning of the Securities Act and must, therefore, deliver a prospectus meeting the requirements of the Securities Act in connection with any resales of the Exchange Notes received by such Broker-Dealer in the Exchange Offer, which prospectus delivery requirement may be satisfied by the delivery by such Broker-Dealer of the Prospectus contained in the Exchange Offer Registration Statement. Such “Plan of Distribution” section shall also contain all other information with respect to such resales by Broker-Dealers that the Commission may require in order to permit such resales pursuant thereto, but such “Plan of Distribution” shall not name any such Broker-Dealer or disclose the amount of Initial Notes held by any such Broker-Dealer except to the extent required by the Commission as a result of a change in policy after the date of this Agreement.

The Company and the Guarantors shall use their commercially reasonable efforts to keep the Exchange Offer Registration Statement continuously effective, supplemented and amended as required by the provisions of Section 6(c) hereof to the extent necessary to ensure that it is available for resales of Initial Notes acquired by Broker-Dealers for their own accounts as a result of market-making activities or other trading activities, and to ensure that it conforms with the requirements of this Agreement, the Securities Act and the policies, rules and regulations of the Commission as announced from time to time, for a period ending on the earlier of (i) 180 days from the date on which the Exchange Offer Registration Statement is declared effective (ii) the date on which a Broker-Dealer is no longer required to deliver a prospectus in connection with market-making or other trading activities and (iii) the date on which all the Initial Notes covered by such Exchange Offer Registration Statement have been sold pursuant to such Exchange Offer Registration Statement.

The Company shall provide sufficient copies of the latest version of such Prospectus to Broker-Dealers promptly upon request at any time during such 180-day (or shorter as provided in the foregoing sentence) period in order to facilitate such resales.

SECTION 4. Shelf Registration.

(a) Shelf Registration. If (i) the Company and the Guarantors are not required to file an Exchange Offer Registration Statement or to consummate the Exchange Offer because the Exchange Offer is not permitted by applicable law or Commission policy (after the procedures set forth in Section 6(a)(i) hereof have been complied with), (ii) for any reason the Exchange Offer is not Consummated within 30 Business Days after the Effectiveness Target Date with respect to the Exchange Offer Registration Statement, or (iii) with respect to any Holder of Transfer Restricted Securities, such holder notifies the Company prior to the 20th day following the consummation of the Exchange Offer that (A) such Holder is prohibited by applicable law or Commission policy from participating in the Exchange Offer, or (B) such Holder may not resell the Exchange Notes 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 (C) such Holder is a Broker-Dealer and holds Initial Notes acquired directly from the Company or one of its Affiliates, then, upon such Holder’s request, the Company and the Guarantors shall

(x) use their commercially reasonable efforts to cause to be filed a shelf registration statement pursuant to Rule 415 under the Securities Act, which may be an amendment to the Exchange Offer Registration Statement (in either event, the “Shelf Registration Statement”), on or prior to 90 days after the filing obligation arises (such date being the “Shelf Filing Deadline”), which Shelf Registration Statement shall provide for resales of all Transfer Restricted Securities the Holders of which shall have provided the information required pursuant to Section 4(b) hereof; and

(y) use their commercially reasonable efforts to cause such Shelf Registration Statement to be declared effective by the Commission on or prior to 270 days after the Shelf Filing Deadline.

The Company and the Guarantors shall use their commercially reasonable efforts to keep such Shelf Registration Statement continuously effective, supplemented and amended as required by the provisions of Sections 6(b) and (c) hereof to the extent necessary to ensure that it is available for resales of Initial Notes by the Holders of Transfer Restricted Securities entitled to the benefit of this Section 4(a), and to ensure that it conforms with the requirements of this Agreement, the Securities Act and the policies, rules and regulations of the Commission as announced from time to time, for a period until the earlier of (i) the expiration of the period referred to in Rule 144(k) under the Securities Act (or any successor rule) with respect to Transfer Restricted Securities, (ii) two years following the effective date of such Shelf Registration Statement and (iii) the date on which all the Initial Notes covered by such Shelf Registration Statement have been sold pursuant to such Shelf Registration Statement.

(b) Provision by Holders of Certain Information in Connection with the Shelf Registration Statement. No Holder of Transfer Restricted Securities may include any of its

Transfer Restricted Securities in any Shelf Registration Statement pursuant to this Agreement unless and until such Holder furnishes to the Company in writing, within 20 days after receipt of a request therefor, such information as the Company may reasonably request for use in connection with any Shelf Registration Statement or Prospectus or preliminary Prospectus included therein. No Holder of Transfer Restricted Securities shall be entitled to Liquidated Damages pursuant to Section 5 hereof unless and until such Holder shall have provided all such information. 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 the information previously furnished to the Company by such Holder not materially misleading.

SECTION 5. Liquidated Damages. (a) If (i) a Shelf Registration Statement is required to be filed by this Agreement and is not filed with the Commission on or prior to the date specified for such filing in this Agreement, (ii) any of the Registration Statements required by this Agreement has not been declared effective by the Commission on or prior to the date specified for such effectiveness in this Agreement (the “Effectiveness Target Date”), (iii) the Exchange Offer has not been Consummated within 30 Business Days after the Effectiveness Target Date with respect to the Exchange Offer Registration Statement or (iv) any Registration Statement required by this Agreement is filed and declared effective but shall thereafter cease to be effective or fail to be usable for its intended purpose (each such event referred to in clauses (i) through (iv), a “Registration Default”), the Company hereby agrees to pay damages (“Liquidated Damages”) to each Holder of the Transfer Restricted Securities in an amount equal to 0.25% per annum on the principal amount of Transfer Restricted Securities held by such Holder during the 90-day period immediately following the occurrence of any Registration Default and such amount shall increase by 0.25% per annum at the end of each subsequent 90-day period, but in no event shall such increase exceed 1.00% per annum. Following the cure of all Registration Defaults relating to any particular Transfer Restricted Securities, the payment of Liquidated Damages shall cease; provided, however, that, if after payment of Liquidated Damages has ceased, a different Registration Default occurs, Liquidated Damages shall again be paid pursuant to the foregoing provisions. All accrued Liquidated Damages shall be paid in the manner provided for the payment of interest on the Initial Notes as set forth in the Indenture.

(b) A Registration Default referred to in Section 5(iv) hereof shall be deemed not to have occurred and be continuing in relation to a Shelf Registration Statement or the related Prospectus if (i) such Registration Default has occurred solely as a result of material events with respect to the Company and the Guarantors that would need to be described in such Shelf Registration Statement or the related Prospectus and such event is not so described therein and (ii) the Company and the Guarantors are proceeding promptly and in good faith to amend or supplement such Shelf Registration Statement and related Prospectus to describe such events; provided, however, that in any case if such Registration Default occurs for a continuous period in excess of 30 days in any 12 month period, Liquidated Damages shall be payable in accordance with the above paragraph from the day such Registration Default occurs until such Registration Default is cured.

All obligations of the Company and the Guarantors set forth in the preceding paragraph that are outstanding with respect to any Transfer Restricted Security at the time such security ceases to be a Transfer Restricted Security shall survive until such time as all such obligations with respect to such Note shall have been satisfied in full.

SECTION 6. Registration Procedures.

(a) Exchange Offer Registration Statement. In connection with the Exchange Offer, the Company and the Guarantors shall comply with all of the provisions of Section 6(c) below, shall use their commercially reasonable efforts to effect such exchange to permit the sale of Transfer Restricted Securities being sold in accordance with the intended method or methods of distribution thereof, and shall comply with all of the following provisions:

(i) If in the reasonable opinion of counsel to the Company there is a question as to whether the Exchange Offer is permitted by applicable law, the Company and the Guarantors hereby agree to seek a no-action letter or other favorable decision from the Commission allowing the Company and the Guarantors to Consummate an Exchange Offer for such Initial Notes. The Company and the Guarantors each hereby agree to pursue the issuance of such a decision to the Commission staff level but shall not be required to take commercially unreasonable action to effect a change of Commission policy. The Company and the Guarantors each hereby agree, however, to (A) participate in telephonic conferences with the Commission, (B) deliver to the Commission staff an analysis prepared by counsel to the Company setting forth the legal bases, if any, upon which such counsel has concluded that such an Exchange Offer should be permitted and (C) diligently pursue a favorable resolution by the Commission staff of such submission.

In addition, all such Holders of Transfer Restricted Securities shall otherwise cooperate in the Company’s preparations for the Exchange Offer. Each Holder, including any Holder that is a Broker-Dealer, shall acknowledge and agree that any such Holder using the Exchange Offer to participate in a distribution of the securities to be acquired in the Exchange Offer (1) could not under Commission policy as in effect on the date of this Agreement rely on the position of the Commission enunciated in Xxxxxx Xxxxxxx & Co., Inc. (available June 5, 1991) and Exxon Capital Holdings Corporation (available May 13, 1988), as interpreted in the Commission’s letter to Shearman & Sterling dated July 2, 1993, and similar no-action letters (which may include any no-action letter obtained pursuant to clause (i) above), and (2) must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a secondary resale transaction and that such a secondary resale transaction should be covered by an effective registration statement containing the selling security holder information required by Item 507 or 508, as applicable, of Regulation S-K if the resales are of Exchange Notes obtained by such Holder in exchange for Initial Notes acquired by such Holder directly from the Company.

(b) Shelf Registration Statement. In connection with the Shelf Registration Statement, if any, the Company and the Guarantors shall comply with all the provisions of Section 6(c) below and shall use their commercially reasonable efforts to effect such registration to permit the sale of the Transfer Restricted Securities being sold in accordance with the intended method or methods of distribution thereof, and pursuant thereto the Company and the Guarantors will as promptly as practicable prepare and file with the Commission a Registration Statement relating to the registration on any appropriate form under the Securities Act, which form shall be available for the sale of the Transfer Restricted Securities in accordance with the intended method or methods of distribution thereof.

(c) General Provisions. In connection with any Registration Statement and any Prospectus required by this Agreement to permit the sale or resale of Transfer Restricted Securities (including, without limitation, any Registration Statement and the related Prospectus required to permit resales of Initial Notes by Broker-Dealers), the Company and the Guarantors shall:

(i) use their commercially reasonable efforts to keep such Registration Statement continuously effective and provide all requisite financial statements including, if required by the Securities Act or any regulation thereunder, financial statements of the Guarantors for the period specified in Section 3 or 4 hereof, as applicable; upon the occurrence of any event that would cause any such Registration Statement or the Prospectus contained therein (A) to contain an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein not misleading or (B) not to be effective and usable for resale of Transfer Restricted Securities during the period required by this Agreement, the Company and the Guarantors shall file promptly an appropriate amendment to such Registration Statement, in the case of clause (A), correcting any such misstatement or omission, and, in the case of either clause (A) or (B), use their commercially reasonable efforts to cause such amendment to be declared effective and such Registration Statement and the related Prospectus to become usable for their intended purpose(s) as soon as practicable thereafter;

(ii) prepare and file with the Commission such amendments and post-effective amendments to the applicable Registration Statement as may be necessary to keep the Registration Statement effective for the applicable period set forth in Section 3 or 4 hereof; cause the Prospectus to be supplemented by any required Prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 under the Securities Act, and to comply fully with the applicable provisions of Rules 424 and 430A under the Securities Act in a timely manner; and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such Registration Statement during the applicable period in accordance with the intended method or methods of distribution by the sellers thereof set forth in such Registration Statement or supplement to the Prospectus;

If at any time the Commission shall issue any stop order suspending the effectiveness of the Registration Statement, or any state securities commission or other regulatory authority shall issue an order suspending the qualification or exemption from qualification of the Transfer Restricted Securities under state securities or blue sky laws, the Company and the Guarantors shall use their commercially reasonable efforts to obtain the withdrawal or lifting of such order at the earliest possible time;

(iv) furnish without charge to each of the Initial Purchasers, each selling Holder named in any Shelf Registration Statement, and each of the underwriter(s), if any, before filing with the Commission, copies of any Shelf Registration Statement or any Prospectus included therein or any amendments or supplements to any such Registration Statement or Prospectus (including all documents incorporated by reference after the initial filing of such Shelf Registration Statement), which documents will be subject to the review and comment of the Initial Purchasers and underwriter(s), if any, in connection with such sale for a period of at least five Business Days, and the Company will not file any such Registration Statement or Prospectus or any amendment or supplement to any such Registration Statement or Prospectus to which the Initial Purchasers or the underwriter(s), if any, shall reasonably object in writing within five Business Days after the receipt thereof (such objection to be deemed timely made upon confirmation of telecopy transmission within such period). The objection of an Initial Purchaser or an underwriter, if any, shall be deemed to be reasonable if such Registration Statement, amendment, Prospectus or supplement, as applicable, as proposed to be filed, contains an untrue statement of a material fact or omits to state a material fact necessary to make the statements therein not misleading;

(v) in connection with any Underwritten Offering, make available at reasonable times for inspection by the Initial Purchasers, any managing underwriter participating in any disposition pursuant to such Registration Statement and any attorney or accountant retained by such Initial Purchaser or any of the underwriter(s), all financial and other records, pertinent corporate documents and properties of the Company and the Guarantors and cause the Company’s and the Guarantors’ officers, directors and employees to supply all information reasonably requested by any such Holder, underwriter, attorney or accountant in connection with such Registration Statement of any post-effective amendment thereto subsequent to the filing thereof and prior to its effectiveness; provided, however, that such Persons first agree in writing with the

Company that any information that is reasonably and in good faith designated by the Company in writing as confidential at the time of delivery of such information will be kept confidential by such Persons, unless (A) disclosure of such information is required by court or administrative order or is necessary to respond to inquires of regulatory authorities, (B) disclosure of such information is required by law (including any disclosure requirements pursuant to federal securities laws in connection with the filing of such Shelf Registration Statement or the use of any Prospectus), (C) such information becomes generally available to the public other than as a result of a disclosure or failure to safeguard such information by such Person or (D) such information becomes available to such Person from a source other than the Company and its subsidiaries and such source is not known, after reasonable inquiry, by such Person to be bound by a confidentiality agreement; provided further that, to the extent the foregoing investigation is being made contemporaneously by more than two Holders, there shall be one law firm and one accounting firm retained by all Holders to make such investigation;

(vi) in connection with any Underwritten Offering, if requested by any selling Holders or the underwriter(s), incorporate in any Registration Statement or Prospectus, pursuant to a supplement or post-effective amendment if necessary, such information as such selling Holders and underwriter(s), if any, may reasonably request to have included therein, including, without limitation, information relating to the “Plan of Distribution” of the Transfer Restricted Securities, information with respect to the principal amount of Transfer Restricted Securities being sold to such underwriter(s), the purchase price being paid therefor and any other terms of the offering of the Transfer Restricted Securities to be sold in such offering; and make all required filings of such Prospectus supplement or post-effective amendment as soon as practicable after the Company is notified of the matters to be incorporated in such Prospectus supplement or post-effective amendment;

(vii) furnish to each Initial Purchaser, each selling Holder, who so reasonably requests, and each of the underwriter(s), if any, without charge, at least one copy of the Shelf Registration Statement, as first filed with the Commission, and of each amendment thereto, including financial statements and schedules and all documents incorporated by reference therein and all exhibits (including exhibits incorporated therein by reference);

(ix) in the case of a Shelf Registration Statement involving an Underwritten Offering, enter into, and cause the Guarantors to enter into, such agreements (including an underwriting agreement), and make, and cause the Guarantors to make, such representations and warranties, and take all such other actions in connection therewith in order to expedite or facilitate the disposition of the Transfer Restricted Securities pursuant to such Underwritten Offering, all to such extent as may be reasonably

requested by an Initial Purchaser or, to the extent customary for such transaction, by any Holder of Transfer Restricted Securities or underwriter in connection with any sale or resale pursuant to such Underwritten Offering; and the Company and the Guarantors shall:

(x) cooperate with, and cause the Guarantors to cooperate with, the selling Holders and the underwriter(s), if any, to facilitate the timely preparation and delivery of certificates representing Transfer Restricted Securities to be sold and not bearing any restrictive legends; and enable such Transfer Restricted Securities to be in such denominations and registered in such names as the Holders or the underwriter(s), if any, may request at least two Business Days prior to any sale of Transfer Restricted Securities made by such Holders or underwriter(s);

(xii) if any fact or event contemplated by Section 6(c)(iii)(D) hereof shall exist or have occurred, prepare a supplement or post-effective amendment to the Registration Statement or related Prospectus or any document incorporated therein by reference or file any other required document so that, as thereafter delivered to the purchasers of Transfer Restricted Securities, the Prospectus will not contain an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein not misleading;

If so directed by the Company, each Holder will deliver to the Company (at the Company’s expense) all copies, other than permanent file copies then in such Holder’s possession, of the Prospectus covering such Transfer Restricted Securities that was current at the time of receipt of such notice. In the event the Company shall give any such notice, the time period regarding the effectiveness of such Registration Statement set forth in Section 3 or 4 hereof, as applicable, shall be extended by the number of days during the period from and including the date of the giving of such notice pursuant to Section 6(c)(iii)(D) hereof to and including the date when each selling Holder covered by such Registration Statement shall have received the copies of the supplemented or amended Prospectus contemplated by Section 6(c)(xii) hereof or shall have received the Advice.

SECTION 7. Registration Expenses.

(a) All expenses incident to the Company’s or the Guarantors’ performance of or compliance with this Agreement will be borne by the Company and the Guarantors, regardless of whether a Registration Statement becomes effective, including, without limitation: (i) all registration and filing fees and expenses (including filings made by any Initial Purchaser or Holder with the NASD (and, if applicable, the fees and expenses of any “qualified independent underwriter” and its counsel that may be required by the rules and regulations of the NASD)); (ii) all fees and expenses of compliance with federal securities and state securities or blue sky laws; (iii) all expenses of printing (including printing certificates for the Exchange Notes to be issued in the Exchange Offer and printing of Prospectuses), messenger and delivery services and telephone; (iv) all fees and disbursements of counsel for the Company, and the Guarantors and, subject to Section 7(b) hereof, the Holders of Transfer Restricted Securities; and (v) all fees and disbursements of independent certified public accountants of the Company and the Guarantors (including the expenses of any special audit and comfort letters required by or incident to such performance).

The Company and the Guarantors will, in any event, bear their internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing

legal or accounting duties), the expenses of any annual audit and the fees and expenses of any Person, including special experts, retained by the Company or the Guarantors.

(b) In connection with any Registration Statement required by this Agreement (including, without limitation, the Exchange Offer Registration Statement and the Shelf Registration Statement), the Company and the Guarantors will reimburse the Initial Purchasers and the Holders of Transfer Restricted Securities being tendered in the Exchange Offer and/or resold pursuant to the “Plan of Distribution” contained in the Exchange Offer Registration Statement or registered pursuant to the Shelf Registration Statement, as applicable, for the reasonable fees and disbursements of not more than one counsel, who shall be Shearman & Sterling LLP or such other counsel as may be chosen by the Holders of a majority in principal amount of the Transfer Restricted Securities for whose benefit such Registration Statement is being prepared.

(c) Each Holder will pay all underwriting discounts and commissions and transfer taxes, if any, relating to the sale or disposition of such Holder’s Transfer Restricted Securities pursuant to the Shelf Registration Statement.

SECTION 8. Indemnification.

(a) Each of the Company and the Guarantors, jointly and severally, agree to indemnify and hold harmless each Holder, its directors, officers and employees, and each Person, if any, who controls any Holder within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act against any loss, claim, damage, liability or expense, as incurred, to which such Holder or such 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 and/or the Guarantors), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement or Prospectus (or any amendment or supplement thereto) or any free writing prospectus or preliminary prospectus used in any transaction contemplated hereby, or the omission or alleged omission therefrom of 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 to reimburse each Holder and each such controlling person for any and all expenses (including the fees and disbursements of counsel chosen by such Holder or such controlling person) as such expenses are reasonably incurred by such Holder or such controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the foregoing indemnity agreement shall not apply to any loss, claim, damage, liability or expense (including without limitation and as incurred, reimbursement of all reasonable costs of investigating, preparing, pursuing, settling, compromising, paying or defending any claim or action, or any investigation or proceeding by any governmental agency or body, commenced or threatened, including the reasonable fees and expenses of counsel to any such indemnified person) to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Company by any of the Holders expressly for use in any Registration Statement

or Prospectus (or any amendment or supplement thereto) or any free writing prospectus or preliminary prospectus used in any transaction contemplated hereby. The indemnity agreement set forth in this Section 8(a) shall be in addition to any liabilities that the Company or the Guarantors may otherwise have.

(b) Each Holder agrees, severally and not jointly, to indemnify and hold harmless the Company, the Guarantors and each of their respective directors, officers and employees and each Person, if any, who controls the Company or any Guarantor 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 the Company or the Guarantors or any such 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 such Holder or such controlling person), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) (i) arises out of or is based upon any untrue or alleged untrue statement of a material fact contained in any Registration Statement or Prospectus (or any amendment or supplement thereto) or any free writing prospectus or preliminary prospectus used in connection with any transaction contemplated hereby, or (ii) arises out of or is based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in any Registration Statement or Prospectus (or any amendment or supplement thereto) or any free writing prospectus or preliminary prospectus used in connection with any transaction contemplated hereby, in reliance upon and in conformity with written information furnished to the Company by such Holder expressly for use therein; and to reimburse the Company, the Guarantors or any such director, officer, employee or controlling person for any legal and other expenses reasonably incurred by the Company, the Guarantors or any such director, officer, employee or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. The indemnity agreement set forth in this Section 8(b) shall be in addition to any liabilities that such Holder may otherwise have. In no event shall the liability of any selling Holder hereunder be greater than the dollar amount of the proceeds received by such Holder upon the sale of the Transfer Restricted Securities giving rise to such indemnification obligation.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof, but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party for contribution or otherwise than under the indemnity agreement contained in this Section 8 or to the extent it is not prejudiced as a proximate result of such failure. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the

indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnified party or parties 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 party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, which such approval shall not be unreasonably withheld, the indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the immediately preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (together with local counsel), approved by the indemnifying party, representing the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action, in each of which cases the reasonable fees and expenses of counsel shall be at the expense of the indemnifying party.

The indemnifying party under this Section 8 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 against any loss, claim, damage, liability or expense by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, 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 party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding.

(d) If the indemnification provided for in this Section 8 is for any reason held to be unavailable to or otherwise insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, 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 and the Guarantors, on the one hand, and the Holders, on the other hand, from the Initial Placement (which in the case of the Company and the Guarantors shall be deemed to be equal to the total gross proceeds to the Company and the Guarantors from the Initial Placement and the Registration Statement) or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Guarantors, on the one hand, and the Holders, on the other hand, in connection with the statements or omissions or inaccuracies in the representations and warranties herein which resulted in such losses, claims,

damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative fault of the Company and the Guarantors, 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 omission or alleged omission to state a material fact or any such inaccurate or alleged inaccurate representation or warranty relates to information supplied by the Company or the Guarantors, on the one hand, or the Holders, on the other hand, 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 a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in this Section 8, any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The provisions set forth in Section 8(c) with respect to notice of commencement of any action shall apply if a claim for contribution is to be made hereunder; provided, however, that no additional notice shall be required with respect to any action for which notice has been given under Section 8(c) for purposes of indemnification.

The Company, the Guarantors and each Holder of Transfer Restricted Securities agree that it would not be just and equitable if contribution pursuant to this Section 8 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 which does not take account of the equitable considerations referred to in this Section 8.

Notwithstanding the provisions of this Xxxxxxx 0, xxxx of the Holders (or any Person who controls such Holder within the meaning of the Securities Act and the Exchange Act) shall be required to contribute, in the aggregate, any amount in excess of the amount by which the net proceeds received by such Holder from the sale of the Transfer Restricted Securities pursuant to a Registration Statement exceeds the amount of any damages which 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 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, and not joint, in proportion to the respective principal amount of Initial Notes held by each of the Holders hereunder and not joint. For purposes of this Section 8(d), each director, officer and employee of each Holder and each Person, if any, who controls any Holder within the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as such Holder, and each director, officer and employee of the Company or any Guarantor, and each Person, if any, who controls the Company or any Guarantor within the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as the Company or any Guarantor.

SECTION 9. Rule 144A. The Company and the Guarantors each hereby agrees with each Holder, for so long as any Transfer Restricted Securities remain outstanding, to make available to any Holder or beneficial owner of Transfer Restricted Securities in connection with any sale thereof and any prospective purchaser of such Transfer Restricted Securities from such

Holder or beneficial owner, the information required by Rule 144A(d)(4) under the Securities Act in order to permit resales of such Transfer Restricted Securities pursuant to Rule 144A under the Securities Act.

SECTION 10. Participation in Underwritten Registrations. No Holder may participate in any Underwritten Registration hereunder unless such Holder (a) agrees to sell such Holder’s Transfer Restricted Securities on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements and (b) completes and executes all reasonable questionnaires, powers of attorney, indemnities, underwriting agreements, lock-up letters and other documents required under the terms of such underwriting arrangements.

SECTION 11. Selection of Underwriters. The Holders of Transfer Restricted Securities covered by the Shelf Registration Statement who desire to do so may sell such Transfer Restricted Securities in an Underwritten Offering. In any such Underwritten Offering, the investment banker or investment bankers and manager or managers that will administer the offering will be selected by the Holders of a majority in aggregate principal amount of the Transfer Restricted Securities included in such offering; provided, however, that such investment bankers and managers must be reasonably satisfactory to the Company.

SECTION 12. Miscellaneous.

(a) Remedies. Each of the Company and the Guarantors hereby agree that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it 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. Each of the Company and the Guarantors 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. Neither the Company nor any of the Guarantors have previously entered into any agreement granting any registration rights with respect to its securities to any Person pursuant to which any such Person would have the right to include any securities in any Registration Statement to be filed with the Commission as required under this Agreement. 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 the Company’s securities under any agreement in effect on the date hereof.

(c) Adjustments Affecting the Notes. The Company and the Guarantors will not take any action, or permit any change to occur, with respect to the Initial Notes and/or the Exchange Notes that would materially and adversely affect their ability to Consummate the Exchange Offer.

(d) 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 unless the Company has obtained the written consent of Holders of a majority of the outstanding principal amount of Transfer Restricted Securities.

Notwithstanding the foregoing, a waiver or consent to departure from the provisions hereof that relates exclusively to the rights of Holders whose Transfer Restricted Securities are being tendered pursuant to the Exchange Offer and that does not affect directly or indirectly the rights of other Holders whose securities are not being tendered pursuant to such Exchange Offer may be given by the Holders of a majority of the outstanding principal amount of Transfer Restricted Securities being tendered; provided that, with respect to any matter that directly or indirectly affects the rights of any Initial Purchaser hereunder, the Company shall obtain the written consent of such Initial Purchaser (which consent shall not be unreasonably withheld) with respect to which such amendment, qualification, supplement, waiver, consent or departure is to be effective.

(e) Additional Guarantors. The Company shall cause any of its Restricted Subsidiaries (as defined in the Indenture) that becomes, prior to the consummation of the Exchange Offer, a Guarantor in accordance with the terms and provisions of the Indenture to become a party to this Agreement as a Guarantor. It is understood and agreed that if, prior to the Exchange Offer, a Guarantor that has executed this Agreement is no longer a Guarantor under the Indenture pursuant to and in accordance with the provisions of the Indenture, such Guarantor shall no longer be a Guarantor for purposes of this Agreement.

(f) Notices. All notices and other communications provided for or permitted hereunder shall be made in writing by hand-delivery, first-class mail (registered or certified, return receipt requested), telex, telecopier, or air courier guaranteeing overnight delivery:
