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

(b): The Exchange Notes and the Private Exchange Notes shall be issued under, and entitled to the benefits of the Indenture or a trust indenture that is identical to the Indenture (other than such changes as are necessary to comply with any requirements of the SEC to effect or maintain the qualifications thereof under the TIA) which in either case will provide that (i) the Exchange Notes will not be subject to the transfer restrictions or additional interest provisions set forth in the Indenture, (ii) the Private Exchange Notes will be subject to the transfer restrictions set forth in the Indenture and (iii) the Exchange Notes, the Private Exchange Notes and the Notes, if any, will be deemed one class of security (subject to the provisions of the Indenture) and entitled to participate in all the security granted by the Company pursuant to the Collateral Agreements and in any Guarantee (as such terms are defined in the Indenture) on an equal and ratable basis.
(c): Interest on the Exchange Notes and Private Exchange Notes will accrue from (i) the later of (x) the last interest payment date on which interest was paid on the Notes surrendered in exchange therefor or (y) if the Note is surrendered for exchange on a date in a period which includes the record date for an interest payment date to occur on or after the date of such exchange and as to which interest will be paid, the date of such interest payment date or (ii) if no interest has been paid on the Notes, from the Issue Date. Each Exchange Note and Private Exchange Note shall bear interest at the rate set forth thereon; provided, that interest with respect to the period prior to the issuance thereof shall accrue at the rate or rates borne by the Notes from time to time during such period.
(d): The Company may require each Holder as a condition to participation in the Exchange Offer to represent to the Company that at the time of the consummation of the Exchange Offer, (i) any Exchange Notes received by such Holder will be acquired in the ordinary course of its business, (ii) at the time of commencement and consummation of the Exchange Offer such Holder has not entered into any arrangement or understanding with any Person to participate in the distribution (within the meaning of the Securities Act) of the Exchange Notes in violation of the provisions of the Securities Act, (iii) such Holder is not an "affiliate" (as defined in Rule 405 of the Securities Act) of the Company or if such Holder is an affiliate such Holder will comply with the registration and prospectus delivery requirements of the Securities Act to the extent applicable, (iv) if such Holder is not a broker-dealer, that it is not engaged in, and does not intend to engage in, the distribution of the Exchange Notes and (v) if such Holder is a Participating Broker-Dealer that will receive Exchange Notes for its own account in exchange for Notes that were acquired as a result of market-making or other trading activities, that it will deliver a Prospectus in connection with any resale of the Exchange Notes.
(e): The Company shall (and shall cause each Guarantor to) include within the Prospectus contained in the Exchange Registration Statement a section entitled "Plan of Distribution" which shall contain all of the information that the SEC may require with respect to the potential "underwriter" status of any broker-dealer that is the beneficial owner (as defined in Rule 13d-3 under the Exchange Act) of Exchange Notes received by such broker-dealer in the

Exchange Offer for its own account in exchange for Notes that were acquired by it as a result of market-making activities or other trading activities (a "Participating Broker-Dealer"), whether such positions or policies have been publicly disseminated by the staff of the SEC or such positions or policies, in the judgment of the Initial Purchaser, represent the prevailing views of the staff of the SEC. Such "Plan of Distribution" section shall also allow, to the extent permitted by applicable policies and regulations of the SEC, the use of the Prospectus by all Persons subject to the prospectus delivery requirements of the Securities Act, including, to the extent so permitted, all Participating Broker-Dealers, and include a statement describing the manner in which Participating Broker-Dealers may resell the Exchange Notes. The Company shall use its reasonable best efforts to keep the Exchange Registration Statement effective and to amend and supplement the Prospectus contained therein, in order to permit such Prospectus to be lawfully delivered by all Persons subject to the prospectus delivery requirements of the Securities Act for such period of time as such Persons must comply with such requirements in order to resell the Exchange Notes (the "Applicable Period").

(f)

If, upon consummation of the Exchange Offer, the Initial Purchaser holds any Notes acquired by it and having the status of an unsold allotment in the initial distribution, the Company (upon the written request from the Initial Purchaser) shall, simultaneously with the delivery of the Exchange Notes pursuant to the Exchange Offer, issue and deliver to the Initial Purchaser in exchange (the "Private Exchange") for the Notes held by the Initial Purchaser, a like principal amount at maturity of Senior Secured Notes (issued under the same Indenture as the Exchange Notes) that are identical in all material respects to the Exchange Notes except for the existence of restrictions on transfer thereof under the Securities Act and securities laws of the several states of the United States (the "Private Exchange Notes"). The Private Exchange Notes shall bear the same CUSIP number as the Exchange Notes.

(g)

In connection with the Exchange Offer, the Company shall (and shall cause each Guarantor to):

(i): mail to each Holder a copy of the Prospectus forming part of the Exchange Registration Statement, together with an appropriate letter of transmittal (substantially in the form attached as an exhibit to the Exchange Registration Statement) and any related documents;
(ii): keep the Exchange Offer open for not less than 20 Business Days (or longer if required by applicable law) after the date notice thereof is mailed to the Holders;
(iii): utilize the services of a depository for the Exchange Offer with an address in the Borough of Manhattan, The City of New York, which may be the Trustee or an affiliate thereof;

(i): accept for exchange all Registrable Notes validly tendered and not withdrawn pursuant to the Exchange Offer or the Private Exchange, as the case may be;
(ii): deliver to the Trustee for cancellation all Registrable Notes so accepted for exchange; and
(iii): cause the Trustee to authenticate and deliver promptly to each Holder tendering such Registrable Notes, Exchange Notes or Private Exchange Notes, as the case may be, equal in principal amount at maturity to the Notes of such Holder so accepted for exchange.

(i): If, (i) any change in law or in applicable interpretations thereof by the staff of the SEC would not permit the consummation of the Exchange Offer, (ii) for any other reason the Exchange Registration Statement is not declared effective on or prior to the Effectiveness Date or the Exchange Offer is not consummated within 30 Business Days after the Effectiveness Date, (iii) the Initial Purchaser so requests with respect to the Notes (or the Private Exchange Notes) not eligible to be exchanged for Exchange Notes in the Exchange Offer and held by it following consummation of the Exchange Offer, or (iv) in the case of (A) any Holder not permitted to participate in the Exchange Offer or (B) any Holder participating in the Exchange Offer that receives Exchange Notes that may not be sold or transferred without restriction under state and federal securities laws (other than due solely to the status of such Holder as an affiliate of the Company within the meaning of the Securities Act) and, in either case contemplated by this clause (iv), such Holder notifies the Company within six months of consummation of the Exchange Offer, then in each case the Company shall promptly (and in any event within five Business Days of such notification) deliver to the Holders and the Trustee written notice thereof (the "Shelf Notice") and shall as promptly as practicable and at its sole expense thereafter file an Initial Shelf Registration Statement pursuant to Section 3.

3. Shelf Registration

If a Shelf Notice is delivered pursuant to Section 2(i), then this Section 3 shall apply to all Registrable Notes. Otherwise, upon consummation of the Exchange Offer in accordance with Section 2, the provisions of this Section 3 shall apply solely with respect to (i) Notes held by any Holder thereof not permitted to participate in the Exchange Offer, (ii) Private Exchange Notes, and (iii) Exchange Notes that are not freely transferable as contemplated by Section 2(i)(iv) hereof, provided in each case that the relevant Holder has duly notified the Company within six months of the Exchange Offer as required by Section 2(i)(iv).

(a): Initial Shelf Registration. The Company shall (and shall cause each Guarantor to), as promptly as practicable, file with the SEC a Registration Statement for an offering to be made on a continuous basis pursuant to Rule 415 covering all of the Registrable Notes (the "Initial Shelf Registration Statement") within 30 days of the delivery of the Shelf Notice and shall (and shall cause each Guarantor to) use its best efforts to cause such Initial Shelf Registration Statement to be declared effective under the Securities Act as promptly as practicable thereafter (but in no event more than 90 days after delivery of the Shelf Notice); provided, however, that if the Company (and each Guarantor) has not yet filed an Exchange Registration Statement, the Company shall file (and shall cause each Guarantor to file) with the SEC the Initial Shelf Registration Statement on or prior to the Filing Date and shall use its reasonable best efforts to cause such Initial Shelf Registration Statement to be declared effective under the Securities Act on or prior to the Effectiveness Date. The Initial Shelf Registration Statement shall be on Form S-l or another appropriate form permitting registration of such Registrable Notes for resale by Holders in the manner or manners reasonably designated by them (including, without limitation, Underwritten Offerings). The Company shall (and shall cause each Guarantor to) use its reasonable best efforts to keep the Initial Shelf Registration Statement continuously effective under the Securities Act until date which is two years from the Issue Date (the "Effectiveness Period"), or such shorter period ending when (i) all Registrable Notes covered by the Initial Shelf Registration Statement have been sold in the manner set forth and as contemplated in the Initial Shelf Registration Statement, (ii) a Subsequent Shelf Registration Statement (as defined below) covering all of the Registrable Notes covered by and not sold under the Initial Shelf Registration Statement or an earlier Subsequent Shelf Registration Statement has been declared effective under the Securities Act, (iii) such Registrable Notes are eligible for resale pursuant to Rule 144(k) under the Securities Act or (iv) there cease to be any outstanding Registrable Notes.

(b): Subsequent Shelf Registrations. If the Initial Shelf Registration Statement or any Subsequent Shelf Registration Statement ceases to be effective for any reason at any time during the Effectiveness Period (other than because of the sale of all of the securities registered thereunder), the Company shall (and shall cause each Guarantor to) use its reasonable best efforts to obtain the prompt withdrawal of any order suspending the effectiveness thereof, and in any event shall within 30 days of such cessation of effectiveness amend such Shelf Registration Statement in a manner designed to obtain the withdrawal of the order suspending the effectiveness thereof, or file (and cause each Guarantor to file) an additional "shelf" registration statement pursuant to Rule 415 covering all of the Registrable Notes covered by and not sold under the Initial Registration Statement or any earlier Registration Statement (a "Subsequent Shelf Registration Statement"). If a Subsequent Shelf Registration Statement is filed, the Company shall (and shall cause each Guarantor to) use its reasonable best efforts to cause the Subsequent Shelf Registration Statement to be declared effective as soon as practicable after such filing and to keep such Subsequent Shelf Registration Statement continuously effective for a period equal to the number of days in the Effectiveness Period less the aggregate number of days during which the Initial Shelf Registration Statement or any Subsequent Shelf Registration Statement was previously continuously effective. As used herein the term "Shelf Registration Statement" means the Initial Shelf Registration Statement and any Subsequent Shelf Registration Statements.
(c): Supplements and Amendments. The Company shall promptly supplement and amend any Shelf Registration Statement and/or amend or supplement the Prospectus constituting a part thereof if required by the rules, regulations or instructions applicable to the registration form used for such Shelf Registration Statement, if required by the Securities Act, or if reasonably requested in writing by the Holders of a majority in aggregate principal amount of the Registrable Notes covered by such Shelf Registration Statement or by any underwriter of such Registrable Notes.
(d): Provision of Information. No Holder shall be entitled to include any of its Registrable Notes in any Shelf Registration Statement pursuant to this Agreement unless such Holder furnishes to the Company and the Trustee in writing, within 20 days after receipt of a written request therefor, such information as the Company and the Trustee, after conferring with counsel with regard to information relating to Holders that would be required by the SEC to be included in such Shelf Registration Statement or Prospectus included therein, may reasonably request for inclusion in any Shelf Registration Statement or Prospectus included therein, and no such Holder shall be entitled to Additional Interest pursuant to Section 4 hereof unless and until such Holder shall have provided such information.
(e): Notwithstanding anything to the contrary contained in this Agreement, upon notice to Holders, the Company may suspend use of the Prospectus included in any Shelf Registration Statement in the event that and for a period of time (a "Blackout Period") not to exceed an aggregate of 60 days in any 12-month period if the board of directors of the Company determines in good faith that (1) the disclosure of an event, occurrence or other item at such time could reasonably be expected to have a Material Adverse Effect on the business, operations or prospects of the Company and the Guarantors, taken as a whole, or (2) the disclosure otherwise relates to a material business transaction which has not been publicly disclosed and that any such disclosure would jeopardize the success of the transaction or that disclosure of the transaction is prohibited pursuant to the terms thereof.

4. Additional Interest

(a): The Company and each Guarantor acknowledges and agrees that the Holders of Registrable Notes will suffer damages if the Company or any Guarantor fails to fulfill its material obligations under Section 2 or Section 3 hereof and that it would not be feasible to ascertain

the extent of such damages with precision. Accordingly, the Company and the Guarantors agree to pay additional cash interest on the Notes ("Additional Interest") under the circumstances and to the extent set forth below (each of which shall be given independent effect):

(i): if (A) neither the Exchange Registration Statement nor the Initial Shelf Registration Statement has been filed with the SEC on or prior to the Filing Date or (B) notwithstanding that the Company has consummated or will consummate an Exchange Offer, the Company is required to file a Shelf Registration Statement and such Shelf Registration Statement is not filed on or prior to the date required by this Agreement, then, commencing on the day after either such required filing date, Additional Interest shall accrue on the principal amount of the Notes over and above any stated interest at a rate of 0.25% per annum for the first 90 days immediately following such filing date, such Additional Interest rate increasing by an additional 0.25% per annum at the beginning of each subsequent 90-day period, subject to the provisos in the last sentence of this paragraph;
(ii): if (A) neither the Exchange Registration Statement nor the Initial Shelf Registration Statement is declared effective by the SEC on or prior to the Effectiveness Date, or (B) notwithstanding that the Company has consummated or will consummate an Exchange Offer, the Company is required to file a Shelf Registration Statement and such Shelf Registration Statement is not declared effective by the SEC on or prior to the 90^th day following the date such Shelf Registration Statement was filed, then, commencing on the day after either such required effective date, Additional Interest shall accrue on the principal amount of the Notes over and above any stated interest at a rate of 0.25% per annum for the first 90 days immediately following such effective date, such Additional Interest rate increasing by an additional 0.25% per annum at the beginning of each subsequent 90-day period, subject to the provisos in the last sentence of this paragraph; or
(iii): if (A) the Company (and any Guarantor) has not exchanged Exchange Notes for all Notes validly tendered and not withdrawn in accordance with the terms of the Exchange Offer on or prior to 30 Business Days after the Effectiveness Date, (B) if applicable, a Shelf Registration Statement has been declared effective and such Shelf Registration Statement ceases to be effective or usable in connection with resales of the Notes at any time prior to the second anniversary of the Issue Date (other than during a Blackout Period or after such time as all Notes have been disposed of thereunder), or (C) the Company issues a valid notice to suspend the use of the Prospectus included in any Shelf Registration Statement and such suspension, when taken together with all other suspensions, if any (but solely to the extent not concurrent), during any 12 month period exceeds 60 days, then, in each case, Additional Interest shall accrue on the principal amount of the Notes over and above any stated interest at a rate of 0.25% per annum for the first 90 days commencing on (x) the 31^st Business Day after the Effectiveness Date, in the case of clause (A) above, (y) the day such Shelf Registration Statement ceases to be effective or usable, in the case of clause (B) above, or (z) the day the Prospectus in any Shelf Registration Statement is suspended for any period in excess of 90 Days, in the case of clause (C) above during any 12-month period, such Additional Interest rate increasing by an additional 0.25% per annum at the beginning of each subsequent 90-day period, subject to the provisos in the last sentence of this paragraph;

provided, however, that Additional Interest will not accrue under more than one of the foregoing clauses (i), (ii) or (iii) at any one time; provided further, however, that the amount of Additional Interest accruing on the Notes shall not exceed at any one time in the aggregate

1.0% per annum; and provided further, however, that (1) upon the filing of the Exchange Registration Statement or Initial Shelf Registration Statement (in the case of clause (i) above), (2) upon the effectiveness of the Exchange Registration Statement or Shelf Registration Statement (in the case of clause (ii) above), (3) upon the exchange of Exchange Notes for all Notes tendered (in the case of clause (iii)(A) above), (4) upon the effectiveness of a Shelf Registration Statement which had ceased to remain effective (in the case of clause (iii)(B) above), or (5) upon the day the Prospectus in any Shelf Registration Statement the use of which was previously suspended may be used again (in the case of clause (iii)(C) above), Additional Interest on the Notes as a result of such clause (or the relevant subclause thereof), as the case may be, shall cease to accrue.

(b): The Company shall notify the Trustee within three Business Days after each and every date on which an event occurs in respect of which Additional Interest is required to be paid (an "Event Date"). Any amounts of Additional Interest due pursuant to clause (a)(i), (a)(ii) or (aiii) of this Section 5 will be payable in cash, on the dates and in the manner provided in the Indenture and whether or not any cash interest would then be payable on such date, commencing with the first such semi-annual date occurring after any such Additional Interest commences to accrue. The amount of Additional Interest will be determined by multiplying the applicable Additional Interest rate by the principal amount of the Notes, multiplied by a fraction, the numerator of which is the number of days such Additional Interest rate was applicable during such period (determined on the basis of a 360-day year comprised of twelve 30-day months and, in the case of a partial month, the actual number of days elapsed), and the denominator of which is 360.

5. Hold-Back Agreements

The Company agrees that it will not effect any public or private sale or distribution (including a sale pursuant to Regulation D under the Securities Act) of any securities the same as or similar to those covered by a Registration Statement filed pursuant to Section 2 or 3 hereof (other than Additional Notes (as defined in the Indenture) issued under the Indenture), or any securities convertible into or exchangeable or exercisable for such securities, during the 10 days prior to, and during the 90-day period beginning on, the effective date of any Registration Statement filed pursuant to Sections 2 and 3 hereof unless the Holders of a majority in the aggregate principal amount at maturity of the Registrable Notes to be included in such Registration Statement consent, if the managing underwriter thereof so requests in writing.

6. Registration Procedures

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

(a): Prepare and file with the SEC the Exchange Registration Statement, in accordance with Section 2 or a Shelf Registration Statement in accordance with Section 3; provided that, if (1) a Shelf Registration Statement is filed pursuant to Section 3 or (2) a Prospectus contained in an Exchange Registration Statement filed pursuant to Section 2 is required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during the Applicable Period, before filing any Registration Statement or Prospectus or any amendments or supplements thereto the Company shall (and shall cause each Guarantor to), if requested, furnish at no charge to the Holders of the Registrable Notes to be registered pursuant to such Shelf Registration Statement, each Participating Broker-Dealer, the managing underwriters, if any, and each of their respective counsel, a reasonable opportunity to review

copies of all such documents (including copies of any documents to be incorporated by reference therein and all exhibits thereto) proposed to be filed (in each case at least 5 Business Days prior to such filing). The Company and each Guarantor shall not (and shall not allow any of the other Guarantors to) file any such Registration Statement or Prospectus or any amendments or supplements thereto in respect of which the Holders must provide information for the inclusion therein without the Holders being afforded an opportunity to review such documentation if the holders of a majority in aggregate principal amount of the Registrable Notes covered by such Registration Statement, or any such Participating Broker-Dealer, as the case may be, or the managing underwriters, if any, or any of their respective counsel shall reasonably object in writing prior to such filing date. A Holder shall be deemed to have reasonably objected to such filing 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 any material fact necessary to make the statements therein not misleading or fails to comply with the applicable requirements of the Securities Act.

(b): Provide an indenture trustee for the Registrable Notes, the Exchange Notes or the Private Exchange Notes, as the case may be, and cause the Indenture (or other indenture relating to the Registrable Notes) to be qualified under the TIA not later than the effective date of the first Registration Statement; and in connection therewith, to effect such changes to such indenture as may be required for such indenture to be so qualified in accordance with the terms of the TIA; and execute, and use its reasonable best efforts to cause such trustee to execute, all documents as may be required to effect such changes, and all other forms and documents required to be filed with the SEC to enable such indenture to be so qualified in a timely manner.
(c): Prepare and file with the SEC such pre-effective amendments and post-effective amendments to each Shelf Registration Statement or Exchange Registration Statement, as the case may be, as may be necessary to keep such Registration Statement continuously effective for the Effectiveness Period or the Applicable Period, as the case may be; cause the related Prospectus to be supplemented by any Prospectus supplement required by applicable law, and as so supplemented to be filed pursuant to Rule 424 (or any similar provisions then in force) promulgated under the Securities Act; and comply with the provisions of the Securities Act and the Exchange Act applicable to them with respect to the disposition of all securities covered by such Registration Statement as so amended or in such Prospectus as so supplemented and with respect to the subsequent resale of any securities being sold by a Participating Broker-Dealer covered by any such Prospectus. The Company and each Guarantor shall not (and shall not allow any other Guarantor to), during the Applicable Period, voluntarily take any action that would reasonably be expected to result in selling Holders of the Registrable Notes covered by a Registration Statement or Participating Broker-Dealers seeking to sell Exchange Notes not being able to sell such Registrable Notes or such Exchange Notes during that period, unless such action is required by applicable law, rule or regulation or permitted by this Agreement.
(d): Furnish to such selling Holders and Participating Broker-Dealers who so request in writing (i) upon the Company's receipt, a copy of the order of the SEC declaring such Registration Statement and any post-effective amendment thereto effective, (ii) such reasonable number of copies of such Registration Statement and of each amendment and supplement thereto (in each case including any documents incorporated therein by reference and all exhibits), (iii) such reasonable number of copies of the Prospectus included in such Registration Statement (including each preliminary Prospectus) and each amendment and supplement thereto, and such reasonable number of copies of the final Prospectus as filed by the Company and each Guarantor pursuant to Rule 424(b) under the Securities Act, in conformity with the requirements of the Securities Act and each amendment and supplement thereto, and

8. Indemnification

(a): Indemnification by the Company and the Guarantors. The Company and the Guarantors jointly and severally agree to indemnify and hold harmless each Holder of Registrable Notes, Exchange Notes or Private Exchange Notes and each Participating Broker-Dealer selling Exchange Notes during the Applicable Period, each Person, if any, who controls each such Holder (within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act) and the officers, directors and partners of each such Holder, Participating Broker-Dealer and controlling person, to the fullest extent lawful, from and against any and all losses, claims, damages, liabilities, costs (including, without limitation, reasonable costs of preparation and reasonable attorneys' fees as provided in this Section 8) and expenses (including, without limitation, reasonable costs and expenses incurred in connection with investigating, preparing, pursuing or defending against any of the foregoing) (collectively, "Losses"), as incurred, directly or indirectly caused by, related to, based upon, arising out of or in connection with any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement, Prospectus or form of prospectus, or in any amendment or supplement thereto, or in any preliminary prospectus, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, except insofar as such Losses are primarily based upon information relating to such Holder or Participating Broker-Dealer and furnished in writing to the Company and the Guarantors (or reviewed and approved in writing) by such Holder or Participating Broker-Dealer or their counsel expressly for use therein; provided, however, that the Company and the Guarantors will not be liable to any Indemnified Party (as defined below) under this Section 8 to the extent Losses were primarily caused by an untrue statement or omission or alleged untrue statement or omission that was contained or made in any preliminary prospectus and corrected in the Prospectus or any amendment or supplement thereto if (i) the Prospectus does not contain any other untrue statement or omission or alleged untrue statement or omission of a material fact that was the subject matter of the related proceedings, (ii) any such Losses resulted from an action, claim or suit by any Person who purchased Registrable

Notes or Exchange Notes which are the subject thereof from such Indemnified Party and (iii) it is established in the related proceeding that such Indemnified Party failed to deliver or provide a copy of the Prospectus (as amended or supplemented) to such Person with or prior to the confirmation of the sale of such Registrable Notes or Exchange Notes sold to such Person if required by applicable law, unless such failure to deliver or provide a copy of the Prospectus (as amended or supplemented) was a result of noncompliance by the Company with Section 6 of this Agreement, The Company and the Guarantors also agree to indemnify underwriters, selling brokers, dealer managers and similar securities industry professionals participating in the distribution, their officers, directors, agents and employees and each Person who controls such Persons (within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act) to the same extent as provided above with respect to the indemnification of the Holders or the Participating Broker-Dealer.

(b): Indemnification by Holder. In connection with any Registration Statement, Prospectus or form of prospectus, any amendment or supplement thereto, or any preliminary prospectus in which a Holder is participating, such Holder shall furnish to the Company and the Guarantors in writing such information as the Company and the Guarantors reasonably request for use in connection with any Registration Statement, Prospectus or form of prospectus, any amendment or supplement thereto, or any preliminary prospectus and shall indemnify and hold harmless the Company, the Guarantors, their respective directors and each Person, if any, who controls the Company and the Guarantors (within the meaning of Section 15 of the Securities Act and Section 20(a) of the Exchange Act), and the directors, officers and partners of such controlling persons, to the fullest extent lawful, from and against all Losses arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement, Prospectus or form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading to the extent, but only to the extent, that such losses are finally judicially determined by a court of competent jurisdiction in a final, unappealable order to have resulted primarily from an untrue statement or alleged untrue statement of a material fact or omission or alleged omission of a material fact contained in or omitted from any information so furnished in writing by such Holder to the Company and the Guarantors expressly for use therein. Notwithstanding the foregoing, in no event shall the liability of any selling Holder be greater in amount than such Holder's Maximum Contribution Amount (as defined below).
(c): Conduct of Indemnification Proceedings. If any proceeding shall be brought or asserted against any Person entitled to indemnity hereunder (an "Indemnified Party"), such Indemnified Party shall promptly notify the party or parties from which such indemnity is sought (the "Indemnifying Party" or "Indemnifying Parties", as applicable) in writing; provided, that the failure to so notify the Indemnifying Parties shall not relieve the Indemnifying Parties from any obligation or liability except to the extent (but only to the extent) that it shall be finally determined by a court of competent jurisdiction (which determination is not subject to appeal) that the Indemnifying Parties have been prejudiced materially by such failure.

The Indemnifying Party shall have the right, exercisable by giving written notice to an Indemnified Party, within 20 Business Days after receipt of written notice from such Indemnified Party of such proceeding, to assume, at its expense, the defense of any such proceeding, provided, that an Indemnified Party shall have the right to employ separate counsel in any such proceeding and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party or parties unless: (1) the Indemnifying Party has agreed to pay such fees and expenses; or (2) the Indemnifying Party shall have failed promptly to assume the defense of such proceeding or shall have failed to employ counsel reasonably satisfactory to such Indemnified Party; or

(3) the named parties to any such proceeding (including any impleaded parties) include both such Indemnified Party and the Indemnifying Party or any of its affiliates or controlling persons, and such Indemnified Party shall have been advised by counsel that there may be one or more defenses available to such Indemnified Party that are in addition to, or in conflict with, those defenses available to the Indemnifying Party or such affiliate or controlling person (in which case, if such Indemnified Party notifies the Indemnifying Parties in writing that it elects to employ separate counsel at the expense of the Indemnifying Parties, the Indemnifying Parties shall not have the right to assume the defense and the reasonable fees and expenses of such counsel shall be at the expense of the Indemnifying Party; it being understood, however, that, the Indemnifying Party shall not, in connection with any one such proceeding or separate but substantially similar or related proceedings in the same jurisdiction, arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (together with appropriate local counsel) at any time for such Indemnified Party).

No Indemnifying Party shall be liable for any settlement of any such proceeding effected without its written consent, which shall not be unreasonably withheld, but if settled with its written consent, or if there be a final judgment for the plaintiff in any such proceeding, each Indemnifying Party jointly and severally agrees, subject to the exceptions and limitations set forth above, to indemnify and hold harmless each Indemnified Party from and against any and all Losses by reason of such settlement or judgment. The Indemnifying Party shall not consent to the entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to each Indemnified Party of a release, in form and substance reasonably satisfactory to the Indemnified Party, from all liability in respect of such proceeding for which such Indemnified Party would be entitled to indemnification hereunder (whether or not any Indemnified Party is a party thereto).

(d): Contribution. If the indemnification provided for in this Section 8 is unavailable to an Indemnified Party or is insufficient to hold such Indemnified Party harmless for any Losses in respect of which this Section 8 would otherwise apply by its terms (other than by reason of exceptions provided in this Section 8), then each applicable Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall have a joint and several obligation to contribute to the amount paid or payable by such Indemnified Party as a result of such Losses, in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party, on the one hand, and such Indemnified Party, on the other hand, in connection with the actions, statements or omissions that resulted in such Losses as well as any other relevant equitable considerations. The relative fault of such Indemnifying Party, on the one hand, and Indemnified Party, on the other hand, shall be determined by reference to, among other things, whether any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by such Indemnifying Party or Indemnified Party, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent any such statement or omission. The amount paid or payable by an Indemnified Party as a result of any Losses shall be deemed to include any legal or other fees or expenses incurred by such party in connection with any proceeding, to the extent such party would have been indemnified for such fees or expenses if the indemnification provided for in Section 8(a) or 8(b) was available to such party.

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 8(d) were determined by pro rata allocation or by another method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this Section 8(d), a selling Holder shall not be required to contribute, in the aggregate, any amount in excess of such Holder's Maximum Contribution Amount. A selling Holder's "Maximum Contribution Amount" shall equal the excess of (i) the aggregate proceeds received by such Holder pursuant to the sale of such Registrable Notes or Exchange Notes over (ii) the

aggregate amount of 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(d) are several in proportion to the respective principal amount at maturity of the Registrable Securities held by each Holder hereunder and not joint. The Company's and Guarantors' obligations to contribute pursuant to this Section 8(d) are joint and several.

The indemnity and contribution agreements contained in this Section 8 are in addition to any liability that the Indemnifying Parties may have to the Indemnified Parties.

9. Rules 144 and 144A

The Company covenants that it shall (a) file the reports required to be filed by it (if so required) under the Securities Act and the Exchange Act in a timely manner and, if at any time the Company is not required to file such reports, it will, upon the written request of any Holder of Registrable Notes, make publicly available other information necessary to permit sales pursuant to Rule 144 and 144A and (b) take such further action as any Holder may reasonably request in writing, all to the extent required from time to time to enable such Holder to sell Registrable Notes without registration under the Securities Act pursuant to the exemptions provided by Rule 144 and Rule 144A. Upon the request of any Holder, the Company shall deliver to such Holder a written statement as to whether it has complied with such information requirements.

If any of the Registrable Notes covered by any Shelf Registration Statement are to be sold in an Underwritten Offering, the investment banker or investment bankers and manager or managers that will manage the offering will be selected by the Holders of a majority in aggregate principal amount at maturity of such Registrable Notes to be included in such offering; provided, however, that such investment banker or investment bankers and manager or managers must be reasonably acceptable to the Company.

No Holder of Registrable Notes may participate in any underwritten registration hereunder unless such Holder (a) agrees to sell such Holder's Registrable Notes on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements and (b) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements, lock-up letters and other documents required under the terms of such underwriting arrangements.

11. Miscellaneous

(a): Remedies. In the event of a breach by either the Company or any of the Guarantors of any of their respective obligations under this Agreement, each Holder, in addition to being entitled to exercise all rights provided herein, in the Indenture or, in the case of the Initial Purchaser, in the Purchase Agreement, or granted by law, including recovery of damages, will be entitled to specific performance of its rights under this Agreement. The Company and the Guarantors agree that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by either the Company or any of the Guarantors of any of the provisions of this Agreement and hereby agree, to waive the defense in any action for specific performance that a remedy at law would be adequate.
(b): No Inconsistent Agreements. The Company and each of the Guarantors have not entered, as of the date hereof, and the Company and each of the Guarantors shall not enter, after the date of this Agreement, into any agreement with respect to any of its securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts

with the provisions hereof. Other than any agreements that exist on the date hereof, the Company and each of the Guarantors have not entered and will not enter into any agreement granting any registration rights with respect to any of its securities.

(c)

Adjustments Affecting Registrable Notes. The Company shall not, directly or indirectly, take any action with respect to the Registrable Notes as a class that would 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, other than with the prior written consent of the Holders of not less than a majority in aggregate principal amount at maturity of the then outstanding Registrable Notes in circumstances that would adversely affect any Holders of Registrable Notes; provided, however, that Section 8 and this Section 11(d) may not be amended, modified or supplemented without the prior written consent of each Holder. Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders of Registrable Notes whose securities are being tendered pursuant to the Exchange Offer or sold pursuant to a Notes Registration Statement and that does not directly or indirectly affect, impair, limit or compromise the rights of other Holders of Registrable Notes may be given by Holders of at least a majority in aggregate principal amount at maturity of the Registrable Notes being tendered or being sold by such Holders pursuant to such Notes Registration Statement.
