     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) cause to be filed with the Commission sufficiently promptly so as to avoid a Registration Default with respect to the Exchange Offer, a Registration Statement under the Securities Act relating to the Exchange Securities and the Exchange Offer (the “Exchange Offer Registration Statement”), (ii) use their commercially reasonable efforts to cause such Exchange Offer Registration Statement to become effective under the Securities Act sufficiently promptly so as to avoid a Registration Default with respect to the Exchange Offer, (iii) in connection with the foregoing, file (A) all pre-effective amendments to such Exchange Offer Registration Statement as may be necessary in order to cause such Exchange Offer Registration Statement to become effective, (B) if applicable, a post-effective amendment to such Exchange Offer 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 Securities 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 Exchange Offer Registration Statement, commence the Exchange Offer. The Exchange Offer shall be on the appropriate form permitting registration of the Exchange Securities to be offered in exchange for the Transfer Restricted Securities and to permit resales of Transfer Restricted Securities held by Broker-Dealers as contemplated by Section 3(c) hereof.

     (b) The Company and the Guarantors shall 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 20 Business Days after the date notice of the Exchange Offer is mailed to the Holders. The Company shall cause the Exchange Offer to comply with all applicable federal and state

securities laws. No securities other than the Exchange Securities shall be included in the Exchange Offer Registration Statement. The Company and the Guarantors shall use commercially reasonable efforts to cause the Exchange Offer to be Consummated on the earliest practicable date after the Exchange Offer Registration Statement has become effective, but in no event later than 400 days after the Closing Date (or if such 400th day is not a Business Day, the next succeeding Business Day) (such 400th day herein referred to as the “Exchange Deadline”).

     (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 Initial Securities that are Transfer Restricted Securities 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 Securities 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 Securities 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 Securities held by any such Broker-Dealer except to the extent required by the Commission.

     The Company and the Guarantors shall use 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 Transfer Restricted Securities 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 and (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.

     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 for the Initial Securities because the Exchange Offer is not permitted by applicable law or Commission policy; (ii) for any reason the Exchange Offer for the Initial Securities is not Consummated by the Exchange Deadline; or (iii) with respect to any Holder of Transfer Restricted Securities that is not an Affiliate of the Company or Guarantors (A) such Holder is prohibited by applicable law or Commission policy from participating in the Exchange Offer, (B) such Holder may not resell the

Exchange Securities acquired by it in the Exchange Offer to the public without delivering a prospectus and that the Prospectus contained in the Exchange Offer Registration Statement is not appropriate or available for such resales by such Holder, or (C) such Holder is a Broker-Dealer and holds Initial Securities acquired directly from the Company or one of its Affiliates, then, upon such Holder’s request, the Company and the Guarantors shall (1) if permitted by law, cause the Transfer Restricted Securities of such Holder to be reissued in a form that does not bear any restrictive legends relating to the Securities Act or a restrictive CUSIP number so that such Securities may be sold to the public in accordance with Rule 144 under the Securities Act by a person that is not an Affiliate of the Company or any of the Guarantors where no conditions of Rule 144 are then applicable (other than the holding period requirement in paragraph (d)(1)(ii) of Rule 144 so long as such holding period requirement is satisfied at such time of such reissue) and (2) in the event the Company cannot or does not comply with the provisions of the foregoing clause within 20 Business Days of the later of (I) the date of receipt by the Company of such notice of such Holder and (II) the first to occur of the Exchange Date and the Exchange Deadline (such later date being a “Shelf Filing Deadline”), then the Company and the Guarantors shall

     (x) 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 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 before the 90th day after the Shelf Filing Deadline (or if such 90th day is not a Business Day, the next succeeding Business Day).

Each of the Company and the Guarantors shall keep any such Shelf Registration Statement continuously effective, supplemented and amended as required by the provisions of Sections 6(b) and 6(c) hereof to the extent necessary to ensure that it is available for resales of Transfer Restricted Securities by the Holders 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 of one year following the effective date of such Shelf Registration Statement (or such shorter period that will terminate when all the Transferred Registered Securities covered by such Shelf Registration Statement have been sold pursuant to such Shelf Registration Statement). Each of the Company and the Guarantors shall be deemed not to have used commercially reasonable efforts to keep the Shelf Registration Statement effective during the requisite period if any of the Company or the Guarantors voluntarily takes any action that would result in Holders of Transfer Restricted Securities covered thereby not being able to offer and sell such Transfer Restricted Securities during that period, unless (X) such action is required by applicable law; or (Y) such action is taken by any of the Company or Guarantors in good faith and for valid business reasons (not including avoidance of the Company’s or the Guarantors’ obligations hereunder) including, but not limited to, the acquisition or divestiture of assets, so long as the Company and the Guarantors promptly thereafter comply with the requirements of the last paragraph of Section 6(c) hereof

(the period during which the Shelf Registration Statement is not available under clauses (X) or (Y) above, the “Blackout Period”). The Blackout Period shall not exceed 45 days in any three-month period or 90 days in any twelve-month period.

     (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 ten Business 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. 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. Additional Interest. If (a) the Exchange Offer is not Consummated on or prior to the Exchange Deadline, (b) a Shelf Registration Statement applicable to the Transfer Restricted Securities required to be filed by the terms of this Agreement is not declared effective (or does not automatically become effective) on or prior to the 90th calendar day following any Shelf Filing Deadline (or if such 90th day is not a Business Day, the next succeeding Business Day), or (c) a Shelf Registration Statement applicable to the Transfer Restricted Securities required to be filed by the terms of this Agreement is declared effective (or automatically becomes effective) as required but thereafter fails to remain effective or becomes unusable in connection with resales for more than 30 calendar days, excluding any Blackout Period (each such event referred to in clauses (a) through (c) above, a “Registration Default”), the Company hereby agrees that the interest rate borne by the Transfer Restricted Securities shall be increased by 1.0% per annum (“Additional Interest”) for the period of occurrence of the Registration Default until the earlier of the consummation of the Exchange Offer and such time as no Registration Default is in effect. Following the cure of all Registration Defaults, Additional Interest will cease to accrue and the interest rate on the Transfer Restricted Securities will revert to the original rate; provided, however, that, if after the date such Additional Interest ceases to accrue, another Registration Default occurs, Additional Interest will again commence accruing pursuant to the foregoing provisions.

     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 security 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 applicable provisions of Section 6(c) hereof, shall use 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. As a condition to its participation in the Exchange Offer pursuant to the terms of this Agreement, each Holder of Transfer Restricted Securities shall

furnish, upon the request of the Company, prior to the Consummation thereof, a written representation to the Company (which may be contained in the letter of transmittal contemplated by the Exchange Offer Registration Statement) to the effect that (A) it is not an affiliate (within the meaning of Rule 405 under the Securities Act) of the Company or the Guarantors, (B) it is not engaged in, and does not intend to engage in, and has no arrangement or understanding with any Person to participate in, a distribution (within the meaning of the Securities Act) of the Exchange Securities to be issued in the Exchange Offer and (C) it is acquiring the Exchange Securities in its ordinary course of business. In addition, all such Holders of Transfer Restricted Securities shall otherwise cooperate in the Company’s preparations for the Exchange Offer. Each Holder hereby acknowledges and agrees that any Broker-Dealer and 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 ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ and 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, 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 Securities obtained by such Holder in exchange for Initial Securities acquired by such Holder directly from the Company.

     (b) Shelf Registration Statement. In connection with any Shelf Registration Statement, each of the Company and the Guarantors shall comply with all the provisions of Section 6(c) hereof and shall use 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 each of the Company and the Guarantors will as expeditiously as possible 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 Securities by Broker-Dealers), each of the Company and the Guarantors shall:

     (i) use 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 a material misstatement or omission or (B) not to be effective and usable for resale of Transfer Restricted Securities during the period required by this Agreement, the Company 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 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 purposes 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, as applicable, or such shorter period as will terminate when all Transfer Restricted Securities covered by such Registration Statement have been sold; 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, 430A and 430B 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;

     (iii) advise the underwriters, if any, and selling Holders promptly and, if requested by such Persons, to confirm such advice in writing, (A) when the Prospectus or any prospectus supplement or post-effective amendment has been filed, and, with respect to any Registration Statement or any post-effective amendment thereto, when the same has become effective, (B) of any request by the Commission for amendments to the Registration Statement or amendments or supplements to the Prospectus or for additional information relating thereto, (C) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement under the Securities Act or of the suspension by any state securities commission of the qualification of the Transfer Restricted Securities for offering or sale in any jurisdiction, or the initiation of any proceeding for any of the preceding purposes, (D) of the existence of any fact or the happening of any event that makes any statement of a material fact made in the Registration Statement, the Prospectus, any amendment or supplement thereto, or any document incorporated by reference therein untrue, or that requires the making of any additions to or changes in the Registration Statement or the Prospectus in order to make the statements therein (with respect to the Prospectus, in light of the circumstances under which they were made) not misleading. 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, each of the Company and the Guarantors shall use 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 Registration Statement, and each underwriter, if any, before filing

with the Commission, copies of any 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 Registration Statement), which documents will be subject to the review and comment of such Holders and underwriters in connection with such sale, if any, 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 (including all such documents incorporated by reference) to which an Initial Purchaser of Transfer Restricted Securities covered by such Registration Statement or the underwriters, 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); provided, that this clause (iv) shall not apply to any filing by the Company of any annual report on Form 10-K, quarterly report on Form 10-Q or Current Report on Form 8-K with respect to matters unrelated to the Initial Securities, the Transfer Restricted Securities and the Exchange Securities and the offering or exchange therefor. The objection of an Initial Purchaser or 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 a material misstatement or omission;

     (v) in the case of a Shelf Registration Statement, make available at during normal business hours for inspection by the Initial Purchasers, the managing underwriters, if any, participating in any disposition pursuant to such Registration Statement and any attorney or accountant retained by such Initial Purchasers or any of the underwriters, all financial and other records, pertinent corporate documents and properties of each 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 or any post-effective amendment thereto subsequent to the filing thereof and prior to its effectiveness and to participate in meetings with investors to the extent requested by the managing underwriters, if any;

     (vi) if requested by any selling Holders or the underwriters, if any, promptly incorporate in any Registration Statement or Prospectus, pursuant to a supplement or post-effective amendment if necessary, such information as such selling Holders and underwriters, 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 underwriters, 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) in the case of a Shelf Registration Statement, furnish to each Initial Purchaser, each selling Holder and each of the underwriters, if any, without charge, at

least one copy of the Registration Statement, as first filed with the Commission, and of each amendment thereto, including financial statements and schedules, all documents incorporated by reference therein and all exhibits (including exhibits incorporated therein by reference);

     (viii) deliver to each selling Holder and each of the underwriters, if any, without charge, as many copies of the Prospectus (including each preliminary prospectus) and any amendment or supplement thereto as such Persons reasonably may request; each of the Company and the Guarantors hereby consents to the use of the Prospectus and any amendment or supplement thereto by each of the selling Holders and each of the underwriters, if any, in connection with the offering and the sale of the Transfer Restricted Securities covered by the Prospectus or any amendment or supplement thereto;

     (ix) in the case of a Shelf Registration Statement, enter into such agreements (including an underwriting agreement), and 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 any Registration Statement contemplated by this Agreement, all to such extent as may be requested by any Initial Purchaser or by any Holder of Transfer Restricted Securities or underwriter in connection with any sale or resale pursuant to any Registration Statement contemplated by this Agreement; and, whether or not an underwriting agreement is entered into and whether or not the registration is an Underwritten Registration, each of the Company and the Guarantors shall:

     (A) furnish to each Initial Purchaser, each selling Holder and each underwriter, if any, in such substance and scope as they may request and as are customarily made by Company to underwriters in primary underwritten offerings, upon the effectiveness of the Shelf Registration Statement:

     (1) a certificate, dated the date of effectiveness of the Shelf Registration Statement signed by the principal financial or accounting officer and one additional senior executive officer of the Company, on behalf of the Company and the Guarantors, confirming, as of the date thereof, the matters set forth in Section 5(f) of the Purchase Agreement and such other matters as such parties may reasonably request;

     (2) an opinion, dated the date of effectiveness of the Shelf Registration Statement, as the case may be, of counsel for the Company and the Guarantors, covering the matters set forth in Sections 5(c)-5(d) of the Purchase Agreement and such other matter as such parties may reasonably request; and

     (3) a customary comfort letter, dated the date of effectiveness of the Shelf Registration Statement, from the Company’s independent accountants, in the customary form and covering matters of the type customarily requested to be covered in comfort letters by underwriters in connection with primary underwritten offerings, and covering or affirming

the matters set forth in the comfort letters delivered pursuant to Section 5(a) of the Purchase Agreement, without exception;

     (B) set forth in full or incorporate by reference in the underwriting agreement, if any, the indemnification provisions and procedures of Section 8 hereof with respect to all parties to be indemnified pursuant to said Section; and

     (xiv) 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, in light of the circumstances under which they were made, not misleading;

     (xv) provide a CUSIP number for all Exchange Securities not later than the effective date of the Registration Statement covering such Exchange Securities and provide the Trustee under the Indenture with printed certificates for such Exchange Securities which are in a form eligible for deposit with the Depository Trust Company and take all other action necessary to ensure that all such Exchange Securities are eligible for deposit with the Depository Trust Company;

     (xvi) cooperate and assist in any filings required to be made with the FINRA and in the performance of any due diligence investigation by any underwriter (including any “qualified independent underwriter” as that term is defined within the rules and regulations of the FINRA) that is required to be retained in accordance with the rules and regulations of the FINRA;

     (xvii) otherwise use commercially reasonable efforts to comply with all applicable rules and regulations of the Commission, and make generally available to its security holders, as soon as practicable, a consolidated earnings statement meeting the requirements of Rule 158 under the Securities Act (which need not be audited) for the twelve-month period (A) commencing at the end of any fiscal quarter in which Transfer Restricted Securities are sold to underwriters in a firm commitment or best efforts Underwritten Offering or (B) if not sold to underwriters in such an offering, beginning with the first month of the Company’s first fiscal quarter commencing after the effective date of the Registration Statement;

     (xviii) cause the Indenture to be qualified under the Trust Indenture Act not later than the effective date of the first Registration Statement required by this Agreement, and, in connection therewith, cooperate with the Trustee and the Holders of the Initial Securities to effect such changes to the Indenture as may be required for such Indenture to be so qualified in accordance with the terms of the Trust Indenture Act; and to execute and use commercially reasonable efforts to cause the Trustee to execute, all documents that may be required to effect such changes and all other forms and documents required to be filed with the Commission to enable such Indenture to be so qualified in a timely manner; and

     (xix) in the case of a Shelf Registration Statement, cause all Transfer Restricted Securities covered by such Shelf Registration Statement to be listed on each securities exchange or automated quotation system on which similar securities issued by the

Company are then listed if requested by the Holders of a majority in aggregate principal amount of Initial Securities or the managing underwriters, if any.

     Each Holder agrees by acquisition of a Transfer Restricted Security that, upon receipt of any notice from the Company of the existence of any fact of the kind described in Section 6(c)(iii)(D) hereof or any Blackout Period described in Section 4(a) hereof, such Holder will forthwith discontinue disposition of Transfer Restricted Securities pursuant to the applicable Registration Statement until such Holder’s receipt of the copies of the supplemented or amended Prospectus contemplated by Section 6(c)(xiv) hereof, or until it is advised in writing (the “Advice”) by the Company that the use of the Prospectus may be resumed, and has received copies of any additional or supplemental filings that are incorporated by reference in the Prospectus. 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 or notice of any Blackout Period 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)(xiv) hereof or shall have received the Advice.

     SECTION 7. Registration Expenses.

     (a) All expenses incident to the Company’s and the Guarantors’ performance of or compliance with this Agreement will be borne by the Company and the Guarantors, jointly and severally, 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 FINRA (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 FINRA)); (ii) all fees and expenses of compliance with federal securities and state securities or blue sky laws; (iii) all expenses of printing (including printing of Prospectuses), if any, messenger and delivery services and telephone; (iv) all fees and disbursements of counsel for the Company, 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).

     Each of the Company and the Guarantors will, in any event, bear its 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 Shelf Registration Statement required by this Agreement, the Company and the Guarantors, jointly and severally, will reimburse the Initial Purchasers and the Holders of Transfer Restricted Securities being registered pursuant to the Shelf Registration Statement, as applicable, for the reasonable fees and disbursements of not more than one

counsel, who shall be ▇▇▇▇▇ ▇▇▇▇▇ L.L.P. 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.

     SECTION 8. Indemnification.

     (a) The Company and the Guarantors, jointly and severally, agree to indemnify and hold harmless (i) each Holder and (ii) each Person, if any, who controls (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) any Holder (any of the Persons referred to in this clause (ii) being hereinafter referred to as a “controlling person”) and (iii) the respective officers, directors, partners, employees, representatives and agents of any Holder or any controlling person (any Person referred to in clause (i), (ii) or (iii) may hereinafter be referred to as an “Indemnified Holder”), to the fullest extent lawful, from and against any and all losses, claims, damages or liabilities (or actions in respect thereof) including, without limitation, and as incurred, reimbursement of each such Indemnified Holder for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim damage, liability or action, joint or several, directly or indirectly arising out of or 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 omission or alleged omission to state therein a material fact or necessary to make the statements therein (with respect to the Prospectus, in light of the circumstances under which they were made) not misleading, except insofar as such losses, claims, damages, liabilities or actions are caused by an untrue statement or omission or alleged untrue statement or omission that is made in reliance upon and in conformity with information relating to any of the Holders furnished in writing to the Company by any of the Holders expressly for use therein. This indemnity agreement shall be in addition to any liability which the Company or any of the Guarantors may otherwise have.

     In case any action or proceeding (including any governmental or regulatory investigation or proceeding) shall be brought or asserted against any of the Indemnified Holders with respect to which indemnity may be sought against the Company or the Guarantors, such Indemnified Holder (or the Indemnified Holder controlled by such controlling person) shall promptly notify the Company and the Guarantors in writing; provided, however, that the failure to give such notice shall not relieve the Company or any of the Guarantors of their respective obligations pursuant to this Agreement. Such Indemnified Holder shall have the right to employ its own counsel in any such action and the fees and expenses of such counsel shall be paid, as incurred, by the Company and the Guarantors (regardless of whether it is ultimately determined that an Indemnified Holder is not entitled to indemnification hereunder). The Company and the Guarantors shall not, in connection with any one such action or proceeding or separate but substantially similar or related actions or proceedings in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) at any time for such Indemnified Holders, which firm shall be designated by the Holders. The Company and the Guarantors shall be liable for any settlement of any such action or proceeding effected with the Company’s and the Guarantors’ prior written consent, and each of the Company and the Guarantors agrees to indemnify and hold harmless any Indemnified Holder from and against any

loss, claim, damage, liability or expense by reason of any settlement of any action effected with the written consent of the Company and the Guarantors. The Company and the Guarantors shall not, without the prior written consent of each Indemnified Holder, settle or compromise or consent to the entry of judgment in or otherwise seek to terminate any pending or threatened action, claim, litigation or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not any Indemnified Holder is a party thereto), unless such settlement, compromise, consent or termination includes an unconditional release of each Indemnified Holder from all liability arising out of such action, claim, litigation or proceeding.

     (b) Each Holder agrees, severally and not jointly, to indemnify and hold harmless the Company, the Guarantors and their respective directors, officers of the Company and the Guarantors who sign a Registration Statement, and any Person controlling (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) the Company or any of the Guarantors, and the respective officers, directors, partners, employees, representatives and agents of each such Person, to the same extent as the foregoing indemnity from the Company and the Guarantors to each of the Indemnified Holders, but only with respect to claims and actions based on information relating to such Holder furnished in writing by such Holder expressly for use in any Registration Statement or Prospectus. In case any action or proceeding shall be brought against the Company, the Guarantors or their respective directors or officers or any such controlling person in respect of which indemnity may be sought against a Holder of Transfer Restricted Securities, such Holder shall have the rights and duties given the Company and the Guarantors, and the Company, the Guarantors, their respective directors and officers and such controlling person shall have the rights and duties given to each Holder by the preceding paragraph.

     (c) If the indemnification provided for in this Section 8 is unavailable to an indemnified party under Section 8(a) or (b) hereof (other than by reason of exceptions provided in those Sections) in respect of any losses, claims, damages, liabilities or actions referred to therein, then each applicable indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities 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), the amount of Additional Interest which did not become payable as a result of the filing of the Registration Statement resulting in such losses, claims, damages, liabilities or actions, and such Registration Statement, or if such allocation is not permitted by applicable law, 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 which resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative fault of the Company and the Guarantors on the one hand and of the Indemnified Holder on the other 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 Company or any of the Guarantors, on the one hand, or the Indemnified 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 actions referred to above shall be deemed to include, subject to the limitations set forth in the second paragraph of Section 8(a) hereof, any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim.

     The Company, the Guarantors and each Holder agree that it would not be just and equitable if contribution pursuant to this Section 8(c) 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 the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or actions referred to in the immediately preceding paragraph 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 8, in no event shall any Holder (and its related Indemnified Holders) be required to contribute, in the aggregate, any amount in excess of the amount by which the total price at which the Initial Securities sold by such Holder exceeds the amount of any damages that such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. The Holders’ obligations to contribute pursuant to this Section 8(c) are several in proportion to the respective principal amount of Initial Securities held by each of the Holders hereunder and not joint.

     SECTION 9. Rule 144A. Each of the Company and the Guarantors 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 bankers and managing underwriter(s) that will administer such 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 banker(s) and managing underwriters must be reasonably satisfactory to the Company.

     SECTION 12. Miscellaneous.

     (a) Remedies. Each of the Company and the Guarantors hereby agrees 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. 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 or any of the Guarantors’ securities under any agreement in effect on the date hereof.

     (c) Adjustments Affecting the Securities. The Company will not take any action, or permit any change to occur, with respect to the Initial Securities that would materially and adversely affect the ability of the Holders to Consummate any 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 (i) in the case of Section 5 hereof and this Section 12(d)(i), obtained the written consent of Holders of all outstanding Transfer Restricted Securities and (ii) in the case of all other provisions hereof, obtained the written consent of Holders of a majority of the outstanding principal amount of Transfer Restricted Securities (excluding any Transfer Restricted Securities held by the Company or its Affiliates). Notwithstanding the foregoing, a waiver or consent to departure from the provisions hereof that relates exclusively to the rights of Holders whose 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 or registered; provided, however, 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 each such Initial Purchaser with respect to which such amendment, qualification, supplement, waiver, consent or departure is to be effective.

     (e) 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:
