The Exchange Offer shall not be subject to any conditions, other than that the Exchange Offer does not violate any applicable law or applicable interpretations of the Staff.

The Company and the Guarantors agree to use all commercially reasonable efforts to keep the Shelf Registration Statement continuously effective until the second anniversary of the Issue Date or such shorter period that will terminate when all the Entitled Securities covered by the Shelf Registration Statement have been sold pursuant to the Shelf Registration Statement (the “Shelf Effectiveness Period”). The Company and the Guarantors further agree to supplement or amend the Shelf Registration Statement and the related Prospectus if required by the rules, regulations or instructions applicable to the registration form used by the Company and the Guarantors for such Shelf Registration Statement or by the Securities Act or by any other rules and regulations thereunder or if reasonably requested by a Holder of Entitled Securities with respect to information relating to such Holder, and to use their commercially reasonable efforts to cause any such amendment to become effective, if required, and such Shelf Registration Statement and Prospectus to become usable as soon as thereafter practicable. Upon the written request of Holders of Entitled Securities, the Company and the Guarantors agree to furnish to such Holders copies of any such supplement or amendment promptly after its being used or filed with the SEC.

Each Holder shall pay all underwriting discounts and commissions, brokerage commissions and transfer taxes, if any, relating to the sale or disposition of such Holder’s Entitled Securities pursuant to the Shelf Registration Statement.

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

Special Interest shall be paid upon the occurrence of the earliest of the following (each, a “Registration Default”):

(i) The Company and the Guarantors do not file the Exchange Offer Registration Statement within the 180-day period commencing on the Issue Date;

(ii) The Exchange Offer Registration Statement, if filed, has not become effective within the 270-day period commencing on the Issue Date (the “Target Registration Date”);

(iii) The Company and the Guarantors do not consummate the Exchange Offer within 30 Business Days of the Target Registration Date;

(iv) The Exchange Offer Registration Statement has become effective and thereafter either ceases to be effective or the Prospectus contained therein ceases to be usable, in each case whether or not permitted by this Agreement, at any time during the applicable Exchange Dates;

-8-

(v) The Company and the Guarantors do not file the Shelf Registration Statement, if required hereby, within the 60-day period commencing on the day the obligation to file such Shelf Registration Statement arises;

(vi) The Shelf Registration Statement, if filed, has not become effective within the 120 day-period commencing on the day the obligation to file such Shelf Registration Statement arises; or

(vii) The Shelf Registration Statement, if required hereby, has become effective and thereafter either ceases to be effective or the Prospectus contained therein ceases to be usable, in each case whether or not permitted by this Agreement, at any time during the Shelf Effectiveness Period.

Special Interest shall, for the first 90-day period immediately following the first Registration Default, be equal to 0.25% per annum of the principal amount of Entitled Securities then outstanding, and shall increase by an additional 0.25% per annum with respect to each subsequent 90-day period, until all Registration Defaults have been cured. Notwithstanding the foregoing, Special Interest for all Registration Defaults shall not exceed 1.0% per annum of the principal amount of the Entitled Securities then outstanding.

Subject to the limitation set forth in the next succeeding paragraph and subject to the provisions of Section 3 of this Agreement, the Company shall be entitled to delay the initial filing of the Shelf Registration Statement, suspend its obligation to file any amendment to the Shelf Registration Statement, furnish any supplement or amendment to a Prospectus included in the Shelf Registration Statement, make any other filing with the SEC that would be incorporated by reference into the Shelf Registration Statement, cause the Shelf Registration Statement to remain effective or take any similar action (collectively, “Registration Actions”) if there is a possible acquisition or business combination or other transaction, business development or event involving the Company and its subsidiaries that may require disclosure in the Shelf Registration Statement and the Company determines in the exercise of its good faith judgment that such disclosure is not in the best interest of the Company and its stockholders or obtaining any financial statements relating to any such acquisition or business combination required to be included in the Shelf Registration Statement would be impracticable or upon any event described in Section 3(a)(v)(5). Upon the occurrence of any of the conditions described in the foregoing sentence, the Company shall give prompt notice (a “Suspension Notice”) thereof to the Holders. Upon the termination of such condition, the Company shall give prompt notice thereof to the Holders and shall promptly proceed with all Registration Actions that were suspended pursuant to this paragraph.

-9-

The Company may suspend Registration Actions pursuant to the preceding paragraph for one or more periods (each, a “Suspension Period”) not to exceed 90 days in the aggregate during any twelve month period, during which no Special Interest shall be payable pursuant to this Section 2(d) as a result thereof. If one or more Suspension Periods exceed 90 days in the aggregate during any twelve month period, then Special Interest shall begin to accrue on the 91st day until such Registration Default is cured. Each Suspension Period shall be deemed to begin on the date the relevant Suspension Notice is given to the Holders and shall end on the date on which the Company gives the Holders a notice that the Suspension Period has terminated; however, if any delay pursuant to the preceding paragraph and/or this paragraph causes the suspension of the disposition of Entitled Securities pursuant to a Registration Statement, then the relevant Suspension Period shall instead be deemed to end on the date the Holders of such Entitled Securities shall have received copies of the supplemented or amended Prospectus necessary to resume such dispositions. The Company shall at all times use its commercially reasonable efforts to end any Suspension Period at the earliest practicable time. The Company and the Guarantors shall extend the period during which a Registration Statement shall be maintained effective pursuant to this Agreement by the number of days equal to the aggregate of all Suspension Periods relating to such Registration Statement.

All accrued Special Interest will be paid by the Company and the Guarantors on the next scheduled interest payment date to the depositary of the Entitled Securities or its nominee by wire transfer of immediately available funds or by federal funds check and to holders of Entitled Securities in registered certificated form by wire transfer to the accounts specified by them or by mailing checks to their registered addresses if no such accounts have been specified.

(e) Without limiting the remedies available to the Initial Purchasers and the Holders, the Company and the Guarantors acknowledge that any failure by the Company or any Guarantor to comply with their obligations under Sections 2(a) and 2(b) hereof may result in material irreparable injury to the Initial Purchasers or the Holders for which there is no adequate remedy at law, that it will not be possible to measure damages for such injuries precisely and that, in the event of any such failure, the Initial Purchasers or any Holder may obtain such relief as may be required to specifically enforce the Company’s and the Guarantors’ obligations under Sections 2(a) and 2(b) hereof.

(f) Each of the Company and the Guarantors represents, warrants and covenants that it (including its agents and representatives) will not prepare, make, use, authorize, approve or refer to any Free Writing Prospectus.

(xiv) if reasonably requested by any Holder of Entitled Securities covered by a Shelf Registration Statement, promptly include in a Prospectus supplement or post-effective amendment such information with respect to such Holder as such Holder reasonably requests to be included therein and make all required filings of such Prospectus supplement or such post-effective amendment promptly after the Company has received notification of the matters to be so included in such filing, and in any event within 30 days of the receipt of such notification;

(xv) in the case of a Shelf Registration, enter into such customary agreements and take all such other reasonable actions in connection therewith (including those reasonably requested by the Holders of a majority in principal amount of the Entitled Securities covered by the Shelf Registration Statement) in order to expedite or facilitate the disposition of such Entitled Securities including, but not limited to, an Underwritten Offering and in such connection, (1) to the extent possible, make such representations and warranties to the Holders and any Underwriters of such Entitled Securities with respect to the business of the Company and its subsidiaries and the Registration Statement, Prospectus and documents incorporated by reference or deemed incorporated by reference, if any, in each case, in form, substance and scope as are customarily made by issuers to underwriters in underwritten offerings and confirm the same if and when requested, (2) use commercially reasonable efforts to obtain opinions of counsel to the Company and the Guarantors (which counsel and opinions, in form, scope and substance, shall be reasonably satisfactory to the Holders and such Underwriters and their respective counsel), addressed to each selling Holder and Underwriter of Entitled Securities, covering the matters customarily covered in opinions requested in underwritten offerings, (3) use commercially reasonable efforts to obtain “comfort” letters from the independent certified public accountants of the Company and the Guarantors (and, if necessary, any other certified public accountant of any direct or indirect subsidiary of the Company or the Guarantors, or of any business acquired by the Company or the Guarantors for which financial statements and financial data are or are required to be included or incorporated by reference in the Registration Statement) addressed to each selling Holder (to the extent permitted by applicable professional standards) and Underwriter of Entitled Securities, such letters to be in customary form and covering matters of the type customarily covered in “comfort” letters in connection with underwritten offerings, including but not limited to financial information contained in any preliminary prospectus or Prospectus and (4) deliver such documents and certificates as may be reasonably requested by the Holders of a majority in principal amount of the Entitled Securities being sold or the Underwriters, and which are customarily delivered in underwritten offerings, to evidence the continued validity of the representations and warranties of the Company and the Guarantors made pursuant to clause (1) above and to evidence compliance with any customary conditions contained in an underwriting agreement; and

-14-

(xvi) so long as any Entitled Securities remain outstanding, cause any successor to the Guarantors to execute a counterpart to this Agreement in the form attached hereto as Annex A and to deliver such counterpart to the Initial Purchasers no later than five Business Days following the execution thereof.

(b) In the case of a Shelf Registration Statement, the Company may require each Holder of Entitled Securities to furnish to the Company such information regarding such Holder and the proposed disposition by such Holder of such Entitled Securities as the Company and the Guarantors may from time to time reasonably request in writing. The Company and the Guarantors shall be entitled to refuse to include for registration the Entitled Securities held by any Holder who fails to comply with the request within five Business Days of the receipt of such request to the extent such information is required by applicable law to be included in the Shelf Registration Statement, and such Holder shall not be entitled to benefit from the provisions of Section 2(d) herein.

(c) In the case of a Shelf Registration Statement, each Holder of Entitled Securities covered in such Shelf Registration Statement agrees that, upon receipt of any notice from the Company and the Guarantors of the happening of any event of the kind described in Section 3(a)(v)(3) or 3(a)(v)(5) hereof, such Holder will forthwith discontinue disposition of Entitled Securities pursuant to the Shelf Registration Statement until such Holder’s receipt of the copies of the supplemented or amended Prospectus contemplated by Section 3(a)(ix) hereof, or until it is advised in writing by the Company that the use of the Prospectus may be resumed, and, if so directed by the Company and the Guarantors, such Holder will deliver to the Company or the Guarantors all copies in its possession, other than permanent file copies then in such Holder’s possession, of the Prospectus covering such Entitled Securities that is current at the time of receipt of such notice.

-15-

(d) The Holders of Entitled Securities covered by a Shelf Registration Statement who desire to do so may sell such Entitled Securities in an Underwritten Offering. In any such Underwritten Offering, the investment bank or investment banks and manager or managers (each an “Underwriter”) that will administer the offering will be selected by the Holders of a majority in principal amount of the Entitled Securities included in such offering. No Holder may participate in any Underwritten Offering unless such Holder (i) agrees to sell such Holder’s Securities on the basis provided in any underwriting arrangements approved by the persons entitled hereunder to approve such arrangements and (ii) completes and executes all reasonable questionnaires, powers of attorney, indemnities, underwriting agreements, lock-up letters and other documents, under customary terms, and required under the terms of such underwriting arrangements.

4. Participation of Broker-Dealers in Exchange Offer.

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

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

(b) In light of the above, and notwithstanding the other provisions of this Agreement, upon the written request of a Participating Broker-Dealer, the Company and the Guarantors agree to amend or supplement as soon as reasonably practicable the Prospectus contained in the Exchange Offer Registration Statement for a period of up to 180 days after the last Exchange Date (as such period may be extended pursuant to Section 2(d) of this Agreement), in order to expedite or facilitate the disposition of any Exchange Securities by Participating Broker-Dealers consistent with the positions of the Staff recited in Section 4(a) above. The Company and the Guarantors further agree that Participating Broker-Dealers shall be authorized to deliver such Prospectus (or, to the extent permitted by law, make available) during such period, and only during such period, in connection with the resales contemplated by this Section 4.

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

-16-

5. Indemnification and Contribution.

(a) The Company and the Guarantors, jointly and severally, agree to indemnify and hold harmless each Initial Purchaser and each Holder, their respective affiliates, directors and officers and each Person, if any, who controls any Initial Purchaser or any Holder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred promptly following receipt of a request therefor), joint or several, that arise out of, or are based upon, (1) any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement or any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein not misleading, or (2) any untrue statement or alleged untrue statement of a material fact contained in any Prospectus, any Free Writing Prospectus used in violation of this Agreement or any “issuer information” (“Issuer Information”) filed or required to be filed pursuant to Rule 433(d) under the Securities Act, or any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Initial Purchaser or information relating to any Holder furnished to the Company or in writing through the Representatives or any selling Holder, respectively, expressly for use therein. In connection with any Underwritten Offering permitted by Section 3, the Company and the Guarantors, jointly and severally, will also indemnify the Underwriters, if any, selling brokers, dealers and similar securities industry professionals participating in the distribution, their respective affiliates and each Person who controls such Persons (within the meaning of the Securities Act and the Exchange Act) to the same extent as provided above with respect to the indemnification of the Holders, if requested in connection with any Registration Statement, any Prospectus, any Free Writing Prospectus or any Issuer Information.

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

-17-

(c) If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any Person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such Person (the “Indemnified Person”) shall promptly notify the Person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under this Section 5 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under this Section 5. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 5 that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm (x) for any Initial Purchaser, its affiliates, directors and officers and any control Persons of such Initial Purchaser shall be designated in writing by the Representatives, (y) for any Holder, its directors and officers and any control Persons of such Holder shall be designated in writing by the Majority Holders and (z) in all other cases shall be designated in writing by the Company. The Indemnifying Person 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 Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (A) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (B) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

-18-

(d) To the extent the indemnification provided for in paragraphs (a) or (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantors from the offering of the Securities and the Exchange Securities, on the one hand, and by the Holders from receiving Securities or Exchange Securities registered under the Securities Act, on the other hand, or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company and the Guarantors on the one hand and the Holders on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative fault of the Company and the Guarantors on the one hand and the Holders 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 and the Guarantors or by the Holders and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) The Company, the Guarantors and the Holders agree that it would not be just and equitable if contribution pursuant to this Section 5 were determined by pro rata allocation (even if the Holders were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 5, in no event shall a Holder be required to contribute any amount in excess of the amount by which the greater of (x) the total price at which the Securities or Exchange Securities sold by such Holder and (y) the aggregate principal amount of the Securities exchanged or sold by such Holder exceeds the amount of any damages that such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. The Holders’ obligations to contribute pursuant to this Section 5 are several and not joint.

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

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

-19-

6. General.

(a) No Inconsistent Agreements. The Company and the Guarantors represent, warrant and agree that (i) the rights granted to the Holders hereunder do not in any way conflict with and are not inconsistent with the rights granted to the holders of any other outstanding securities issued or guaranteed by the Company or any Guarantor under any other agreement and (ii) neither the Company nor any Guarantor has entered into, or on or after the date of this Agreement will enter into, any agreement that is inconsistent with the rights granted to the Holders of Entitled Securities in this Agreement or otherwise conflicts with the provisions hereof.

(b) Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given unless the Company and the Guarantors have obtained the written consent of Holders of at least a majority in aggregate principal amount of the outstanding Entitled Securities affected by such amendment, modification, supplement, waiver or consent; provided that no amendment, modification, supplement, waiver or consent to any departure from the provisions of Section 5 hereof shall be effective as against any Holder of Entitled Securities unless consented to in writing by such Holder. Notwithstanding the foregoing, a waiver or consent to departure from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders whose Entitled Securities are being tendered pursuant to the Exchange Offer, and that does not affect directly or indirectly the rights of other Holders whose Entitled 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 Entitled Securities subject to such Exchange Offer. Any amendments, modifications, supplements, waivers or consents pursuant to this Section 6(b) shall be by a writing executed by each of the parties hereto.

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

-20-

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

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

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

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

(h) Governing Law. This Agreement, and any claim, controversy or dispute arising under or related to this Agreement, shall be governed by and construed in accordance with the laws of the State of New York without regard to conflict of law principles that would result in the application of any laws other than the laws of the State of New York.

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

-21-

(j) Securities Held by the Company. Whenever the consent or approval of Holders of a specified percentage of principal amount of Entitled Securities is required hereunder, Entitled Securities held by the Company or its affiliates (other than subsequent Holders of Entitled Securities if such subsequent Holders are deemed to be affiliates solely by reason of their holdings of such Entitled Securities) shall not be counted in determining whether such consent or approval was given by the Holders of such required percentage.
