The Company agrees to use its reasonable best efforts to cause the Exchange Registration Statement to become effective under the Securities Act as soon as practicable, but no later than 180 days after the Closing Date. The Exchange Offer will be registered under the Securities Act on the appropriate form and will comply with all applicable tender offer rules and regulations under the Exchange Act. The Company further agrees to use its reasonable best efforts to commence and complete the Exchange Offer promptly, but no later than 30 days after such registration statement has become effective, hold the Exchange Offer open for at least 20 business days and exchange Exchange Securities for all Registrable Securities that have been validly tendered and not validly withdrawn on or prior to the expiration of the Exchange Offer.

With respect to such Exchange Registration Statement, such holders shall have the benefit of the rights of indemnification and contribution set forth in Sections 6(a), (c), (d) and (e) hereof.

(b) If (i) on or prior to the time the Exchange Offer is completed existing Commission interpretations are changed such that the debt securities or the related guarantees received by holders other than Restricted Holders in the Exchange Offer for Registrable Securities are not or would not be, upon receipt, transferable by each such holder without restriction under the Securities Act, (ii) the Exchange Offer has not been completed within 210 days following the Closing Date or (iii) the Exchange Offer is not available to any holder of the Securities, the Company shall, in lieu of (or, in the case of clause (iii), in addition to) conducting the Exchange Offer contemplated by Section 2(a), file under the Securities Act as soon as practicable, but no later than 30 days after the time such obligation to file arises, a “shelf” registration statement providing for the registration of, and the sale on a continuous or delayed basis by the holders of, all of the Registrable Securities, pursuant to Rule 415 or any similar rule that may be adopted by the Commission (such filing, the “Shelf Registration” and such registration statement, the “Shelf Registration Statement”). The Company agrees to use its reasonable best efforts (x) to cause the Shelf Registration Statement to become or be declared effective no later than 120 days after such Shelf Registration Statement is filed and to keep such Shelf Registration Statement continuously effective for a period ending on the earlier of the second anniversary of the Effective Time or such time as there are no longer any Registrable Securities outstanding, provided , however , that no holder shall be entitled to be named as a selling securityholder in the Shelf Registration Statement or to use the prospectus forming a part thereof for resales of Registrable Securities unless such holder is an Electing Holder, and (y) after the Effective Time of the Shelf Registration Statement, promptly upon the request of any holder of Registrable Securities that is not then an Electing Holder, to take any action reasonably necessary to enable such holder to use the prospectus forming a part thereof for resales of Registrable Securities, including, without limitation, any action necessary to identify such holder as a selling securityholder in the Shelf Registration Statement, provided, however, that nothing in this Clause (y) shall relieve any such holder of the obligation to return a completed and signed Notice and Questionnaire to the Company in accordance with Section 3(d)(iii) hereof. The Company further agrees to supplement or make amendments to the Shelf Registration Statement, as and when 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 rules and regulations thereunder for shelf registration, and the Company agrees to furnish to each Electing Holder copies of any such supplement or amendment prior to its being used or promptly following its filing with the Commission.

(c) In the event that (i) the Company has not filed the Exchange Registration Statement or Shelf Registration Statement on or before the date on which such registration statement is required to be filed pursuant to Section 2(a) or 2(b), respectively, or (ii) such Exchange Registration Statement or Shelf Registration Statement has not become effective or been

5

declared effective by the Commission on or before the date on which such registration statement is required to become or be declared effective pursuant to Section 2(a) or 2(b), respectively, or (iii) the Exchange Offer has not been completed within 30 days after the initial effective date of the Exchange Registration Statement relating to the Exchange Offer (if the Exchange Offer is then required to be made) or (iv) any Exchange Registration Statement or Shelf Registration Statement required by Section 2(a) or 2(b) hereof is filed and declared effective but shall thereafter either be withdrawn by the Company or shall become subject to an effective stop order issued pursuant to Section 8(d) of the Securities Act suspending the effectiveness of such registration statement (except as specifically permitted herein) without being succeeded immediately by an additional registration statement or post-effective amendment filed and declared effective (each such event referred to in clauses (i) through (iv), a “Registration Default” and each period during which a Registration Default has occurred and is continuing, a “Registration Default Period”), then, as liquidated damages for such Registration Default, special interest (“Special Interest”), in addition to the Base Interest, shall accrue on the outstanding Securities at a per annum rate of 0.25% for the first 90 days of the Registration Default Period, at a per annum rate of 0.50% for the second 90 days of the Registration Default Period, at a per annum rate of 0.75% for the third 90 days of the Registration Default Period and at a per annum rate of 1.0% thereafter for the remaining portion of the Registration Default Period.
