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 of the SEC.

(b)    In the event that (i) the Company and the Guarantors determine that the Exchange Offer Registration provided for in Section 2(a) above is not available or may not be completed as soon as practicable after the last Exchange Date because it would violate any applicable law or applicable interpretations of the staff of the SEC, (ii) the Exchange Offer is not for any other reason Consummated by February 1, 2018 unless an Exchange Offer Registration Statement has been filed by October 28, 2017 and has not yet been declared effective by the SEC, other than as result of the fault of the Company or the Guarantors, and as a result of SEC review of data or information included or incorporated by reference in such Exchange Offer Registration Statement that would also be included or incorporated in a Shelf Registration Statement, the Company and the Guarantors reasonably believe that a Shelf Registration Statement would not become effective prior to consummation of the Exchange Offer), or (iii) with respect to any Holder that is not an affiliate of the Company or Guarantors (A) such Holder is prohibited by applicable law or SEC policy from participating in the Exchange Offer, (B) such Holder may not resell the Exchange Securities acquired by it in the Exchange Offer to the public without delivering a prospectus and that the Prospectus contained in the Exchange Offer Registration Statement is not appropriate or available for such resales by such Holder, or (C) such Holder is a Participating Broker-Dealer and holds Registrable Securities acquired directly from the Company or one of its affiliates, then, upon such Holder’s written request within six months of the first to occur of the Exchange Date or the Target Registration Date, the Company and the Guarantors shall (1) if permitted by law and SEC policy, cause the Registrable Securities of such Holder to be reissued in a form that does not bear any restrictive legends relating to the Securities Act and does not have a restrictive CUSIP number so that such Registrable Securities may be sold to the public in accordance with Rule 144 under the Securities Act by a person that is not an affiliate of the Company or any of the Guarantors where no conditions of Rule 144 are then applicable (other than the holding period requirement in paragraph (d)(1)(ii) of Rule 144 so long as such holding period requirement is satisfied at such time of such reissue) and (2) in the event the Company cannot or does not comply with the provisions of the foregoing clause within 20 Business Days of the later of (I) the date of receipt by the Company of such notice of such Holder and (II) the first to occur of the Exchange Date and the Target Registration Date (such later date being a “ Shelf Filing Deadline ”), then the Company and the Guarantors shall use their commercially reasonable best efforts to cause to be filed as soon as practicable after such determination date, a Shelf Registration Statement providing for the sale of all the Registrable Securities by the Holders thereof and to have such Shelf Registration Statement become effective.

In the event that the Company and the Guarantors are required to file a Shelf Registration Statement pursuant to clause (iii) of the preceding sentence, the Company and the Guarantors shall use their commercially reasonable best efforts to file and become effective both an Exchange Offer Registration Statement pursuant to Section 2(a) with respect to all Registrable Securities and a Shelf Registration Statement (which may be a combined Registration Statement with the Exchange Offer Registration Statement) with respect to offers and sales of Registrable Securities held by the Initial Purchasers or such Holder after Consummation of the Exchange Offer.

7

The Company and the Guarantors agree to use their commercially reasonable best efforts (i) to cause the registration statement to become effective by the 90 ^th day after the Shelf Filing Deadline and (ii) to keep the Shelf Registration Statement continuously effective until February 1, 2018 or such shorter period that will terminate when all the Registrable 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 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 Registrable Securities with respect to information relating to such Holder, and to use their commercially reasonable best efforts to cause any such amendment to become effective and such Shelf Registration Statement and Prospectus to become usable as soon as thereafter practicable. The Company and the Guarantors agree to furnish to the Holders of Registrable Securities copies of any such supplement or amendment promptly after its being used or filed with the SEC.

(c)    Each of the Company and the Guarantors shall be deemed not to have used commercially reasonable efforts to keep the Shelf Registration Statement effective during the requisite period if any of the Company or the Guarantors voluntarily takes any action that would result in Holders of Registrable Securities covered thereby not being able to offer and sell such Registrable Securities during that period, unless (X) such action is required by applicable law or SEC policy; or (Y) such action is taken by any of the Company or Guarantors in good faith and for valid business reasons (not including avoidance of the Company or the Guarantors obligations hereunder) including, but not limited to, the acquisition or divestiture of assets (the period during which the Shelf Registration Statement is not available under clauses (X) or (Y) above, the “ Blackout Period ”). The Blackout Period shall not exceed 45 days in any three-month period or 90 days in any twelve-month period.

(d)    The Company and the Guarantors shall pay all Registration Expenses in connection with any registration pursuant to Section 2(a) or Section 2(b) hereof. 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 Registrable Securities pursuant to the Shelf Registration Statement.

(e)    An Exchange Offer Registration Statement pursuant to Section 2(a) hereof or 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.

In the event that the Exchange Offer is not Consummated on or prior to February 1, 2018 (the “ Target Registration Date ”), the interest rate on the New Securities will be increased by (i) 0.25% per annum for the first 90-day period payable commencing from one day after the Target Registration Date, and (ii) an additional 0.25% per annum following such 90-day period, in each case until the Exchange Offer is Consummated, such that the maximum rate of additional interest would be .50% per annum, at which time such additional interest will cease to accrue and the interest rate on the New Securities will revert to the original rate.

8

In the event that the Company is obligated to file a Shelf Registration Statement pursuant to Section 2(b), and the Shelf Registration Statement required to be filed thereby does not become effective prior to the 90th day after the obligation to file such Shelf Registration arises pursuant to Section 2(b) (or if such 90 ^th day is not a Business Day, the next succeeding Business Day) (such later date, the “ Shelf Additional Interest Date ”), the interest rate on the New Securities will be increased by (i) 0.25% per annum for the first 90-day period payable commencing from one day after the Shelf Additional Interest Date, and (ii) an additional 0.25% per annum following such 90-day period, in each case until the Shelf Registration Statement becomes effective, such that the maximum rate of additional interest would be .50% per annum, at which time such additional interest will cease to accrue and the interest rate on the New Securities will revert to the original rate.

If 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, and such failure to remain effective or usable exists for more than 30 days (whether or not consecutive) in any 12-month period, excluding any Blackout Period, then the interest rate on the New Securities will be increased by (i) 0.25% per annum for the first 90-day period commencing on the 31st day in such 12-month period and (ii) an additional 0.25% per annum following such 90-day period and ending on such date that the Shelf Registration Statement has again become effective or the Prospectus again becomes usable, such that the maximum rate of additional interest would be .50% per annum of additional interest.

In no event will additional interest accrue under more than one of the foregoing three paragraphs at any one time.

(f)    Any additional interest paid in accordance with this Section 2 shall be liquidated damages and shall be the sole and exclusive remedy available to Holders due to a failure by the Company to comply with their obligations under Section 2(a) and Section 2(b).

(m)    in the case of a Shelf Registration, make available for inspection by a representative of the Holders of the Registrable Securities (an “ Inspector ”), any Underwriter participating in any disposition pursuant to such Shelf Registration Statement, and attorneys and accountants designated by the Holders, at reasonable times and in a reasonable manner, all pertinent financial and other records, documents and properties of the Company and the Guarantors, and cause the respective officers, directors and employees of the Company and the Guarantors to supply all information reasonably requested by any such Inspector, Underwriter, attorney or accountant in connection with a Shelf Registration Statement; provided that if any such information is identified by the Company as being confidential or proprietary, each Person receiving such information shall take such actions as are reasonably necessary to protect the confidentiality of such information to the extent such action is otherwise not inconsistent with, an impairment of or in derogation of the rights and interests of any Inspector, Holder or Underwriter;

(n)    in the case of a Shelf Registration, use their commercially reasonable best efforts to cause all Registrable Securities to be listed on any securities exchange or any automated quotation system on which similar securities issued or guaranteed by any Company or any Guarantor are then listed if requested by the Majority Holders, to the extent such Registrable Securities satisfy applicable listing requirements;

12

(o)    request that each Holder of New Securities to be sold pursuant to the Registration Statement to furnish the Company such information regarding the Holder and the distribution of the New Securities as the Company may from time to time reasonably require for inclusion in the Registration Statement, and the Company may exclude from such registration the New Securities of any Holder that unreasonably fails to furnish such information within a reasonable time after receiving such request;

(p)    in connection with an Underwritten Offering, if requested by any selling Holders or the Underwriters, if any, promptly incorporate in any Registration Statement or Prospectus, pursuant to a supplement or post-effective amendment if necessary, such information as such selling Holders and Underwriters, if any, may reasonably request to have included therein, including, without limitation, information relating to the “Plan of Distribution” of the Registrable Securities, information with respect to the principal amount of Registrable Securities being sold to such Underwriters, the purchase price being paid therefor and any other terms of the offering of the Registrable Securities to be sold in such offering; and make all required filings of such prospectus supplement or post-effective amendment as soon as practicable after the Company is notified of the matters to be incorporated in such prospectus supplement or post-effective amendment, subject to the provisions applicable to Exchange Offer Registration Statement Suspension Periods and Blackout Periods and the other provisions of this Section 3;

(q)    otherwise use commercially reasonable efforts to comply in all material respects with all applicable rules and regulations of the SEC, and make generally available to its security holders, as soon as reasonably practicable, a consolidated earnings statement meeting the requirements of Rule 158 under the Securities Act (which need not be audited) for the 12-month period (i) commencing at the end of any fiscal quarter in which Registrable Securities are sold to underwriters in a firm commitment or best efforts Underwritten Offering or (ii) if not sold to Underwriters in such an offering, beginning with the first month of the Company’s first fiscal quarter commencing after the effective date of the Registration Statement; and

(r)    in the case of a Shelf Registration, enter into such customary agreements and take all such other actions in connection therewith (including those requested by the Holders of a majority in principal amount of the Registrable Securities being sold) in order to expedite or facilitate the disposition of such Registrable Securities including, but not limited to, an Underwritten Offering and in such connection, (i) to the extent possible, make such representations and warranties to the Holders and any Underwriters of such Registrable Securities with respect to the business of the Company and its subsidiaries, 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, (ii) obtain opinions of counsel to the Company (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 (to the extent such Holder has advised the Company that such Holder may have a “due diligence” defense under Section 11 of the Securities Act) and Underwriter of Registrable Securities, covering the matters customarily covered in opinions

13

requested in underwritten offerings, (iii) obtain “comfort” letters from the independent certified public accountants of the Company (and, if necessary, any other certified public accountant of any subsidiary of the Company or any Guarantor, or of any business acquired by the Company or any Guarantor for which financial statements and financial data are or are required to be included in the Registration Statement) addressed to each selling Holder (to the extent permitted by applicable professional standards) and Underwriter of Registrable Securities, such letters to be in customary form and covering matters of the type customarily covered in “comfort” letters in connection with underwritten offerings and (iv) deliver such documents and certificates as may be reasonably requested by the Holders of a majority in principal amount of the Registrable 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 made pursuant to clause (i) above and to evidence compliance with any customary conditions contained in an underwriting agreement.

In the case of a Shelf Registration Statement, the Company may require each Holder of Registrable Securities to furnish to the Company such information regarding such Holder and the proposed disposition by such Holder of such Registrable Securities as the Company may from time to time reasonably request in writing.

Each Holder of Registrable Securities agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 3(e)(v) hereof or any Exchange Offer Registration Statement Suspension Period or any Blackout Period, such Holder will forthwith discontinue disposition of Registrable Securities pursuant to a Registration Statement until such Holder’s receipt of the copies of the supplemented or amended Prospectus contemplated by Section 3(i) hereof or until it is advised in writing by the Company that use of the Prospectus may be resumed and has received copies of any additional or supplemental filings that are incorporated by reference in the Prospectus and, if so directed by the Company, such Holder will deliver to the Company (at the Company’s expense) all copies in its possession, other than permanent file copies then in such Holder’s possession, of the Prospectus covering such Registrable Securities that is current at the time of receipt of such notice.

If the Company shall give any such notice to suspend the disposition of Registrable Securities pursuant to a Registration Statement, the Company shall extend the period during which the Registration Statement shall be maintained effective pursuant to this Agreement by the number of days during the period from and including the date of the giving of such notice to and including the date when the Holders shall have received copies of the supplemented or amended Prospectus necessary to resume such dispositions. The Company may give any such notice so long as there are no more than 90 days during any 365-day period in which such suspensions are in effect.

The Holders of Registrable Securities covered by a Shelf Registration Statement who desire to do so may sell such Registrable Securities in an Underwritten Offering. In any such Underwritten Offering, the investment bank or investment banks and manager or managers (the “ Underwriters ”) that will administer the offering will be selected by the Majority Holders of the Registrable Securities included in such offering; provided that such selections shall be subject to the approval of the Company, which approval shall not unreasonably be withheld.

4.     Participation of Broker-Dealers in Exchange Offer . (a) The staff of the SEC has taken the position that any broker-dealer that receives Exchange Securities for its own account in the Exchange Offer in exchange for New 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 understands that it is the staff of the SEC’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, to the extent permitted by law, made available to purchasers) or specifying the amount of Exchange Securities owned by them, such Prospectus may be delivered by Participating Broker-Dealers 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, the Company agrees to use its commercially reasonable best efforts to amend or supplement the Prospectus contained in the Exchange Offer Registration Statement, as would otherwise be contemplated by Section 3(i), for a period of up to 180 days after the last Exchange Date (as such period may be extended pursuant to the penultimate paragraph of Section 3 of this Agreement), if requested by the Initial Purchasers or by one or more Participating Broker-Dealers, in order to expedite or facilitate the disposition of any Exchange Securities by Participating Broker-Dealers consistent with the positions of the staff of the SEC recited in Section 4(a) above. The Company further agrees that Participating Broker-Dealers shall be authorized to deliver such Prospectus (or, to the extent permitted by law, make available) 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.

5.     Indemnification and Contribution . (a) The Company and each Guarantor, jointly and severally, agrees to indemnify and hold harmless the Initial Purchasers and each Holder, their respective affiliates, directors and officers and each Person, if any, who controls an Initial Purchasers 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), 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 Prospectus 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 made therein, in the light of the circumstances under which they were made, 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

15

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 made 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 the Initial Purchasers or any Holder furnished to the Company in writing by the Initial Purchasers through Wells Fargo Securities, LLC or any selling Holder expressly for use therein.

(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, their respective affiliates, the directors of the Company, each officer of the Company who signed the Registration Statement and each Person, if any, who controls the Company, the Guarantors, the Initial Purchasers 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 or on behalf of such Holder expressly for use in any Registration Statement and any Prospectus.

(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 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

16

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 the Initial Purchasers, their affiliates, directors and officers and any control Persons of an Initial Purchaser shall be designated in writing by the Initial Purchasers, (y) for any Holder, its affiliates, 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. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (1) such settlement is entered into more than 30 days after receipt by the Indemnifying Person of such request and (2) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. 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.

(d)    If the indemnification provided for in paragraphs (a) and (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 New Securities and the Exchange Securities, on the one hand, and by the Holders from receiving New 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.

17

(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 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 total price at which the New Securities or Exchange Securities sold by such Holder exceeds the amount of any damages that such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. The Holders’ obligations to contribute pursuant to this Section 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, their respective affiliates or any Person controlling any Initial Purchaser or any Holder, or by or on behalf of the Company, their respective affiliates or the officers or directors of or any Person controlling the Company, (iii) acceptance of any of the Exchange Securities and (iv) any sale of Registrable Securities pursuant to a Shelf Registration Statement.

6.     General .

(a)     Rule 144A . Each of the Company and the Guarantors hereby agrees with each Holder, for so long as any Registrable Securities remain outstanding, if the Company is no longer required to file reports under the Exchange Act, to make available upon request to any Holder or beneficial owner of Registrable Securities in connection with any sale thereof and any prospective purchaser of such Registrable Securities from such Holder or beneficial owner, the information required by Rule 144A(d)(4) under the Securities Act in order to permit resales of such Registrable Securities pursuant to Rule 144A under the Securities Act.

If any transferee of any Holder shall acquire Registrable Securities in any manner, whether by operation of law or otherwise, such Registrable Securities shall be held subject to all the terms of this Agreement, and by taking and holding such Registrable 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.
