SECTION 4. ShelfRegistration.

-5-

Broker-Dealer and holds Transfer Restricted Securities acquired directly from the Issuer or one of its affiliates, the Company and any Guarantor 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 30th day after the date such obligation arises (such date being the "Shelf Filing Deadline"), which Shelf Registration Statement shall provide for resales of all Transfer Restricted Securities the Holders of which shall have provided the information required pursuant to Section 4(b) hereof; and

(y)use their reasonable best efforts to cause such Shelf Registration Statement to be declared effective by the Commission on or before the later of (A) the 60^th day after the Shelf Filing Deadline or (B) the 270^th day after the Closing Date (such later date being the "Shelf Effectiveness Deadline").

Each of the Company and any Guarantor shall use its reasonable best efforts to keep such Shelf Registration Statement continuously effective, supplemented and amended as required by the provisions of Sections 6(b) and (c) hereof to the extent necessary to ensure that it is available for resales of Transfer Restricted Securities by the Holders of such Securities entitled to the benefit of this Section 4(a), and to ensure that it conforms with the requirements of this Agreement, the Securities Act and the policies, rules and regulations of the Commission as announced from time to time, from the date on which the Shelf Registration Statement is declared effective by the Commission until the expiration of the one-year period referred to in Rule 144 applicable to securities held by non-affiliates under the Securities Act (or shorter period that will terminate when all the Transfer Restricted Securities covered by such Shelf Registration Statement have been sold pursuant to such Shelf Registration Statement; provided that the Issuer may for a period of up to 60 days in any three-month period, not to exceed 90 days in any calendar year, determine that the Shelf Registration Statement is not usable under certain circumstances relating to corporate developments, public filings with the Commission and similar events, and suspend the use of the prospectus that is part of the Shelf Registration Statement.

(b) Provision by Holders of Certain Information in Connection with the Shelf

Registration Statement. No Holder of Transfer Restricted Securities may include any of its Transfer Restricted Securities in any Shelf Registration Statement pursuant to this Agreement unless and until such Holder furnishes to the Issuer in writing, within 20 Business Days after receipt of a request therefor, such information as the Issuer 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 Issuer all information required to be disclosed in order to make the information previously furnished to the Issuer by such Holder not materially misleading.

SECTION 5. Additional Interest. If (i) the Exchange Offer Registration Statement is not filed with the Commission on or prior to the Filing Date, (ii) the Exchange Offer Registration Statement has not been declared effective by the Commission on or prior to the Effectiveness Date, (iii) the Exchange Offer has not been Consummated by the Exchange Date, (iv) any Shelf

-6-

Registration Statement, if required hereby, has not been declared effective by the Commission on or prior to the Shelf Effectiveness Deadline, or (v) any Registration Statement required by this Agreement has been declared effective but ceases to be effective at any time at which it is required to be effective under this Agreement (each such event referred to in clauses (i) through (iv), a "Registration Default"), the Company hereby agrees that the interest rate borne by the Transfer Restricted Securities shall be increased by 0.25% per annum during the 90-day period immediately following the occurrence of any Registration Default and shall increase by 0.25% per annum at the end of each subsequent 90-day period (such increase, "Additional Interest"), but in no event shall such increase exceed 1.00% per annum in the aggregate. On the date all Registration Defaults relating to the particular Transfer Restricted Securities are cured, the interest rate borne by the relevant Transfer Restricted Securities will be reduced to the original interest rate borne by such Transfer Restricted Securities; provided, however, that, if after any such reduction in interest rate, a different Registration Default occurs, the interest rate borne by the relevant Transfer Restricted Securities shall again be increased pursuant to the foregoing provisions.

All obligations of the Company and any Guarantor 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.

All accrued Additional Interest will be paid by the Company and any Guarantor on the next scheduled interest payment date to DTC or its nominee by wire transfer of immediately available funds or by federal funds check and to holders of certificated Transfer Restricted Securities by wire transfer to the accounts specified by them or by mailing checks to their registered addresses if no such accounts have been specified.

The amount of Additional Interest will be determined by multiplying the applicable additional interest rate by the then outstanding principal amount of the Securities and further 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 the denominator of which is 360. Additional Interest pursuant to this Section 5 constitutes liquidated damages with respect to Registration Defaults and shall be the exclusive monetary remedy available to the Holders with respect to any Registration Default.

SECTION 6. Registration Procedures.

(a) Exchange Offer Registration Statement.

(i) In connection with the Exchange Offer, the Company and any Guarantor

shall comply with all of the provisions of Section 6(c) hereof, shall use its reasonable best efforts to effect such exchange to permit the sale of Transfer Restricted Securities being sold in accordance with the intended method or methods of distribution thereof, and if in the reasonable opinion of counsel to the Issuer there is a question as to whether the Exchange Offer is permitted by applicable law, each of the Company and any Guarantor hereby agree to seek a no-action letter or other favorable decision from the Commission allowing the Company and any Guarantor to Consummate an Exchange Offer for such

-7-

Transfer Restricted Securities.

In addition, all such Holders of Transfer Restricted Securities shall otherwise reasonably 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 Xxxxxx Xxxxxxx and Co. Inc.

with the Shelf Registration Statement, each of the Company and any Guarantor shall comply with all the provisions of Section 6(c) hereof and shall use its reasonable best efforts to effect such registration to permit the sale of the Transfer Restricted Securities being sold in accordance

Without limiting the foregoing, such counsel may state further that such counsel assumes no responsibility for, and has not independently verified, the accuracy, completeness or fairness of the financial statements, notes and schedules and other financial data included in any Registration Statement contemplated by this Agreement or the related Prospectus; and

(3) a customary comfort letter, dated the date of effectiveness

of the Exchange Offer Registration Statement or Shelf Registration Statement, from the Issuer'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;

(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 such Section; and

(C)deliver such other documents and certificates as may be reasonably requested by such parties to evidence compliance with Section 6(c)(x)(A) hereof and with any customary conditions contained in the underwriting agreement or other agreement entered into by the Company or any Guarantor pursuant to this Section 6(c)(x), if any.

If at any time the representations and warranties of the Issuer contemplated in Section 6(c)(x)(A)(1) hereof cease to be true and correct, the Issuer shall so advise any Placement Agent and the underwriter(s), if any, and each selling Holder promptly and, if requested by such Persons, shall confirm such advice in writing;

(xi) prior to any public offering of Transfer Restricted Securities, reasonably

-13-

underwriter(s), if any, may reasonably request in writing and do any and all other acts or things reasonably necessary or advisable to enable the disposition in such jurisdictions of the Transfer Restricted Securities covered by the Shelf Registration Statement; provided, however, that none of the Issuer, the Co-Issuer or any Guarantor shall be required to register or qualify as a foreign corporation or other entity as a dealer in securities in any jurisdiction where it would not otherwise be required to so qualify or file any general consent to service of process in any such jurisdiction or to take any action that would subject it to general service of process in any such jurisdiction where it is not then so subject or to suits or to taxation, other than as to matters and transactions relating to the Registration Statement, in any jurisdiction where it is not then so subject;

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

(xiv)use its reasonable best efforts to cause the Transfer Restricted Securities covered by the Registration Statement to be registered with or approved by such other governmental agencies or authorities as may be reasonably necessary to enable the seller or sellers thereof or the underwriter(s), if any, to consummate the disposition of such Transfer Restricted Securities, subject to the proviso contained in Section 6(c)(x) hereof;

(xv)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 in which they were made, not misleading;

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

necessary to ensure that all such Securities are eligible for deposit with the Depository Trust Company;

(xvii)reasonably 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") that is required to be retained in accordance with the rules and regulations of FINRA, provided that any such underwriters if requested by the Issuer shall agree to keep any information obtained in the course of such due diligence investigation confidential pursuant to the terms of a confidentiality agreement reasonably acceptable to the Issuer;

(xviii)otherwise use its reasonable best 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 Issuer's first fiscal quarter commencing after the effective date of the Registration Statement;

(xix)cause the Indenture to be qualified under the Trust Indenture Act in connection with the registration of the Transfer Restricted Securities, and, in connection therewith, cooperate with the Trustee and the Holders of 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 its reasonable best efforts to cause the Trustee to execute, all documents that may be reasonably 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;

(xx)use its reasonable best efforts to cause all Securities covered by the Registration Statement to be listed on each securities exchange or automated quotation system on which similar securities issued by the Issuer are then listed if requested by the Holders of a majority in aggregate principal amount of Securities or the managing underwriter(s), if any; and

(W) provide promptly to each Holder upon request each document filed with

the Commission pursuant to the requirements of Section 13 and Section 15 of the Exchange Act.

Section 6(c)(iii)(D) 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)(xv) hereof, or until it is advised in writing (the "Advice") by the Issuer that the use of the Prospectus may be resumed, and has received copies of any additional or supplemental filings

-15-

that are incorporated by reference in the Prospectus.

SECTION 7. Registration Expenses.

(a)All expenses incidental to the Issuer's, the Co-Issuer's and any Guarantor's performance of or compliance with this Agreement will be borne by the Company and any Guarantor, 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 the Placement Agent or Holder with 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 FINRA but only where the need for such a "qualified independent underwriter" arises due to a relationship with the Company and any Guarantor)); (ii) all fees and expenses of compliance with federal securities and state securities or blue sky laws; (iii) all expenses of printing (including printing certificates for the Exchange Securities to be issued in the Exchange Offer and printing of Prospectuses), messenger and delivery services and telephone; (iv) all fees and disbursements of counsel for the Issuer, the Co-Issuer any Guarantor and, subject to Section 7(b) hereof, the Holders of Transfer Restricted Securities; (v) all application and filing fees in connection with listing the Exchange Securities on a securities exchange or automated quotation system pursuant to the requirements thereof; and (vi) all fees and disbursements of independent certified public accountants of the Company and any Guarantor (including the expenses of any special audit and comfort letters required by or incident to such performance).

Each of the Issuer, the Co-Issuer and any Guarantor 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 Issuer or the Co-Issuer.

(b)In connection with any Registration Statement required by this Agreement (including, without limitation, the Exchange Offer Registration Statement and the Shelf Registration Statement), the Company and any Guarantor, jointly and severally, will reimburse the Placement Agent and the Holders of Transfer Restricted Securities being tendered in the Exchange Offer and/or resold pursuant to the "Plan of Distribution" contained in the Exchange Offer Registration Statement or registered pursuant to the Shelf Registration Statement, as applicable, for the reasonable fees and disbursements of not more than one counsel chosen by the Holders of a majority in principal amount of the Transfer Restricted Securities for whose benefit

-16-

such Registration Statement is being prepared. The Company and any Guarantor shall pay all documentary, stamp, transfer or other transactional taxes attributable to the issuance or delivery of the Exchange Securities in exchange for the Securities; provided, that neither the Issuer nor the Co-Issuer shall be required to pay taxes payable in respect of any transfer involved in the issuance or delivery of any Excjiange,Securities in a name other than that of the Holder thereof in respect of which such Exchange Security is being issued. In no event shall the Issuer, the Co-Issuer or any Guarantor be responsible for any broker or similar commissions of any Holders, or except the extent provided herein, any legal fees or other costs of the Holders.

SECTION 8. Indemnification.

(a) The Company and any Guarantor, 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, liabilities, judgments, actions and expenses (including, without limitation, and as incurred, reimbursement of all reasonable costs of investigating, preparing, pursuing, settling, compromising, paying or defending any action, claim or proceeding, or any investigation or proceeding by any governmental agency or body, commenced or threatened, including the reasonable fees and expenses of counsel to any Indemnified Holder), joint or several, directly or indirectly caused by, related to, based upon, arising out of or in connection with any untrue statement of a material fact 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 required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made (in the case of the Prospectus), not misleading; provided, however, that none of the Issuer, the Co-Issuer or any Guarantor will be liable insofar as such losses, claims, damages, liabilities, costs or expenses are caused by an untrue statement of a material fact or omission or alleged untrue statement of a material fact or omission to state a material fact that is made in reliance upon and in conformity with information relating to any of the Holders furnished in writing to the Issuer by any of the Holders expressly for use therein. This indemnity agreement shall be in addition to any liability which the Issuer, the Co-Issuer or any Guarantor may otherwise have.

In case any action, claim 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 Issuer, the Co-Issuer or any Guarantor, such Indemnified Holder (or the Indemnified Holder controlled by such controlling person) shall promptly notify the Company and any Guarantor in writing; provided, however, that the failure to give such notice shall not relieve the Issuer, the Co-Issuer or any Guarantor of its obligations pursuant to this Agreement, except to the extent that it has been materially prejudiced by such failure. 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 any Guarantor (regardless of whether it is ultimately determined that an

-17-

Indemnified Holder is not entitled to indemnification hereunder). The Company and any Guarantor shall not, in connection with any one such action, claim 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 any Guarantor shall be liable for any settlement of any such action or proceeding effected with the Company's and any Guarantor's prior written consent, which consent shall not be withheld unreasonably, and each of the Company and any Guarantor 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 any Guarantor. The Company and any Guarantor 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 of Transfer Restricted Securities agrees, severally and not jointly, to indemnify and hold harmless the Issuer, the Co-Issuer, any Guarantor and their respective directors, managers, officers of the Issuer, the Co-Issuer and any Guarantor 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 Issuer, the Co-Issuer or any Guarantor and the respective officers, directors, managers, partners, employees, representatives and agents of each such Person, to the same extent as the foregoing indemnity from the Issuer, the Co-Issuer and any Guarantor to each of the Indemnified Holders, but only with respect to claims, damages, liabilities, judgments, actions and expenses based on information relating to such Holder furnished in writing by such Holder expressly for use in any Registration Statement. In case any action, claim or proceeding shall be brought against the Issuer, the Co-Issuer, any Guarantor or their respective directors, managers 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 any Guarantor, and the Company and any Guarantor, their respective directors, managers 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) or insufficient in respect of any losses, claims, damages, liabilities, judgments, actions, costs or expenses 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, liabilities, costs or expenses in such proportion as is appropriate to reflect the relative benefits received by the Company and any Guarantor, on the one hand, and the Holders, on the other hand, from the Initial Placement (which in the case of the Company and any Guarantor shall be deemed to be equal to the total gross proceeds to the Company and any Guarantor from the Initial Placement), the amount of Additional Interest which did not become payable as a result of the filing of the Registration

-18-

Statement resulting in such losses, claims, damages, liabilities, judgments actions or expenses, or if such allocation is not permitted by applicable law, the relative fault of the Company and any Guarantor, on the one hand, and the Holders, on the other hand, in connection with the statements or omissions that resulted in such losses, claims, damages, liabilities, costs or expenses, as well as any other relevant equitable considerations. The relative fault of the Company and any Guarantor on the one hand and of the Indemnified Holder on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or any Guarantor, 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 Company, any Guarantor and each Holder of Transfer Restricted Securities 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, costs or expenses referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other fees or expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Xxxxxxx 0, xxxx of the Holders (and its related Indemnified Holders) shall be required to contribute, in the aggregate, any amount in excess of the aggregate proceeds of sale of the Transfer Restricted Securities received by such Holder with respect to the Initial Securities exceeds the amount of any damages which such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission to state a material fact. 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 Securities held by each of the Holders hereunder and not joint.

SECTION 9. Rule 144A. Each of the Company and any Guarantor 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 current 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 questionnaires, powers of attorney, indemnities, underwriting agreements, lock-up letters and other documents required under the terms of such underwriting arrangements.

-19-

SECTION 11. Selection of Underwriters. The Holders of Transfer Restricted Securities covered by the Shelf Registration Statement who desire to do so may sell such Transfer Restricted Securities in an Underwritten Offering. In any such Underwritten Offering, the investment banker(s) 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, subject to approval by the Company and any Guarantor, which approval will not be unreasonably withheld.

SECTION 12. Miscellaneous.

(a)Remedies. Each of the Company and any Guarantor 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 agrees 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 any Guarantor 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. Except as described in the Time of Sale Document (as defined in the Placement Agency Agreement), none of the Issuer, the Co-Issuer or any Guarantor has previously entered into any agreement granting any registration rights with respect to its securities to any Person. 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 Guarantor's securities under any agreement in effect on the date hereof, it being acknowledged that registration rights (i) are being granted under the warrant agreement dated the Closing Date among the Issuer, the Co-Issuer and The Bank of New York Mellon Trust Company, N.A., as warrant agent, relating to the Warrants, and (ii) identical to those granted to the holders of the Warrants are expected to be granted to holders of common equity included in the units to be issued to the Issuer's equity sponsor, ORB Investments.

(c)Adjustments Affecting the Securities. Neither the Issuer nor the Co-Issuer will take any action, or permit any change to occur, with respect to the 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 Issuer has (i) in the case of Section 8 hereof and this Section 12(d), 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 in aggregate principal amount of the outstanding Transfer Restricted Securities (excluding any Transfer Restricted Securities held by the Issuer or the Co-Issuer or affiliates thereof). 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 or sold pursuant to a Registration Statement and that does not directly or indirectly affect the rights of other Holders whose securities are not being tendered pursuant to such Exchange Offer or sold pursuant to such Registration Statement may be given by the Holders of a majority of the outstanding principal amount of Transfer Restricted

-20-

Securities being tendered or registered; provided, however, that, with respect to any matter that directly or indirectly affects the rights of the Placement Agent hereunder, the Issuer shall obtain the written consent of the Placement Agent (such consent not to be unreasonably withheld) 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), facsimile, or air courier guaranteeing overnight delivery:
