Securities cease to be Registrable Securities and (ii) the date that is seven years and three months after the date hereof (the “Effectiveness Period”).

     (c) Notwithstanding any other provision hereof, no Holder of Registrable Securities may include any of its Registrable Securities in the Shelf Registration Statement pursuant to this Agreement unless the Holder furnishes to the Company a fully completed notice and questionnaire in the form attached hereto as Exhibit A (the “Questionnaire”) and such other information in writing as the Company may reasonably request in writing for use in connection with the Shelf Registration Statement or Prospectus included therein and in any application to be filed with or under state securities laws.

Registrable Securities pursuant to the Shelf Registration Statement without delivering, or causing to be delivered, a Prospectus (excluding those materials incorporated by reference therein) to the purchaser thereof and, following termination of the Effectiveness Period, to notify the Company, within ten days of a written request by the Company, of the amount of Registrable Securities sold pursuant to the Shelf Registration Statement and, in the absence of a response within such period, the Company may assume that all of such Holder’s Registrable Securities have been so sold.

     (e) The Company agrees that, in the context of a registered Sponsor Supported Distribution and only for the period of 30 days from the earlier of the public announcement or commencement of marketing efforts with respect to such Sponsor Supported Distribution, unless it obtains the prior consent of the managing Underwriter (which consent shall not be unreasonably withheld or delayed), and each Holder agrees that, unless it obtains the prior written consent of the Company, it will not make any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus, or that would otherwise constitute a Free Writing Prospectus required to be filed with the SEC. The Company represents that any Issuer Free Writing Prospectus prepared by it or authorized by it in writing for use by such Holder will be delivered to each such Holder and will not include any information that conflicts with the information contained in the Shelf Registration Statement or the Prospectus and, any such Issuer Free Writing Prospectus, when taken together with the information in the Shelf Registration Statement and the Prospectus, will not include any 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 under which they were made, not misleading.

     The Company agrees to supplement or amend the Shelf Registration Statement if required by the 1933 Act or the rules and regulations thereunder or by the instructions applicable to the registration form used by the Company, or to the extent the Company does not reasonably object, as reasonably requested by the Purchasers with respect to information relating to such Purchasers or by the Trustee on behalf of the Holders covered by such Shelf Registration Statement with respect to information relating to such Holders, and to furnish to the Holders of Registrable Securities copies of any such supplement or amendment promptly after it is used or filed with the SEC.

     2.2 Expenses. The Company shall pay all Registration and Offering Expenses in connection with the registration pursuant to Section 2.1 and, without duplication, in connection with a Sponsor Supported Distribution pursuant to Section 5. Each Holder shall pay all underwriting and placement discounts and commissions, agency and placement fees, brokers commissions and transfer taxes, if any, relating to the sale or disposition of such Holder’s Registrable Securities.

     2.3 Effectiveness. After a Shelf Registration Statement is effective, if the offering of Registrable Securities pursuant to a Shelf Registration Statement is interfered with by any stop order, injunction or other order or requirement of the SEC or any other governmental agency or court, such Shelf Registration Statement will be deemed not to have been effective during the period of such interference, until the offering of Registrable Securities pursuant to such Shelf Registration Statement may legally resume.

     2.4 Interest. In the event that (a) a Shelf Registration Statement has not become effective by the Shelf Effectiveness Deadline, (b) after the Shelf Registration Statement has become effective, subject to Section 2.5, the Shelf Registration Statement fails to be effective or usable by the Holders (determined as if there were no trading restrictions which the Sponsor Purchasers and their Affiliates are subject to under Section 7.1 of the Purchase Agreement at such time) without being succeeded within seven business days by a post-effective amendment or a report filed with the SEC pursuant to the 1934 Act that cures the failure to be effective or usable or (c) the Shelf Registration Statement is unusable by the Holders for any reason (determined as if there were no trading restrictions which the Sponsor Purchasers and their Affiliates are subject to under Section 7.1 of the Purchase Agreement at such time), and the number of days for which the Shelf Registration Statement shall not be usable (determined as if there were no trading restrictions which the Sponsor Purchasers and their Affiliates are subject to under Section 7.1 of the Purchase Agreement at such time) exceeds any Suspension Period permitted by Section 2.5 hereunder (each such event being a “Registration Default”), additional interest (“Additional Interest”), will accrue on the Notes that are Registrable Securities at a rate per annum of 0.25% of the principal amount of the Notes that are Registrable Securities, payable periodically on February 1 and August 1 each year; provided, however, that, in no event shall Additional Interest accrue at a rate per annum exceeding 0.25% of the principal amount of the Notes that are Registrable Securities; provided further that no Additional Interest shall accrue under clauses (b) and (c) above with respect to any Holder that (x) does not deliver to the Company a completed Questionnaire and such other information that the Company may reasonably request, if any, as provided for in Section (c), and (y) is not named as a selling securityholder in the Shelf Registration Statement. Notwithstanding the foregoing, in no event will Additional Interest be payable in connection with a Registration Default relating to a failure to register the Common Stock into which the Notes are convertible; for the avoidance of doubt, if none of the Securities are registered then Additional Interest only will be payable in connection with the Registration Default relating to the failure to register the Notes. Upon the cure of all Registration Defaults then continuing, the accrual of Additional Interest will automatically cease and the interest rate borne by the Notes will revert to the original interest rate at such time. Additional Interest shall be computed based on the actual number of days elapsed in each six-month period between payment dates in which the Shelf Registration Statement is not effective or is unusable. Holders who have converted Notes into Common Stock will not be entitled to receive any Additional Interest with respect to such Common Stock or the principal amount of the Notes converted.

     The Trustee shall be entitled, but shall not be obligated, on behalf of the Holders of Registrable Securities, to seek any available remedy for the enforcement of this Agreement, including for the payment of any Additional Interest. Notwithstanding the foregoing, the parties agree that the sole monetary damages payable for a violation of the terms of this Agreement with respect to which Additional Interest are expressly provided shall be such Additional Interest. Nothing shall preclude a Holder of Registrable Securities from pursuing or obtaining specific performance or equitable relief with regard to this Agreement. Each obligation to pay Additional Interest shall be deemed to accrue from and including the day following the Registration Default to but excluding the day on which the Registration Default is cured.

EXECUTION COPY

     A Registration Default under clause (a) above shall be cured on the date that the Shelf Registration Statement becomes effective. A Registration Default under clauses (b) or (c) above shall be cured on the date an amended Shelf Registration Statement becomes effective or the Company otherwise declares the Shelf Registration Statement and the Prospectus useable, as applicable.

     The parties agree that the Additional Interest provided for in this Section 2.4 constitutes a reasonable estimate of the damages that may be incurred by Holders of Registrable Securities and does not constitute a penalty.

     2.5 Suspension. Notwithstanding any other provision hereof, the Company may suspend the use of any Prospectus, without incurring or accruing any obligation to pay Additional Interest pursuant to Section 2.4, for a period not to exceed 90 consecutive calendar days or an aggregate of 120 calendar days in any twelve-month period, as such period may be reduced pursuant to Section 5(b) hereof (each, a “Suspension Period”), if the Company shall have determined in good faith that because of valid business reasons (not including avoidance of the Company’s obligations hereunder), including without limitation plans for a registered public offering, an acquisition or other proposed or pending corporate developments and similar events or because of filings with the SEC, it is in the best interests of the Company to suspend such use, and prior to suspending such use the Company provides the Holders with written notice of such suspension, which notice need not specify the nature of the event giving rise to such suspension (and, upon receipt of such notice, each Holder agrees not to sell any Registrable Securities pursuant to the Shelf Registration Statement until such Holder is advised in writing that the Prospectus may be used, which notice the Company agrees to provide promptly following the lapse of the event or circumstances giving rise to such suspension). Each Holder shall keep confidential any communications received by it from the Company regarding the suspension of the use of the Prospectus (including, without limitation, the fact of the suspension), except as required by applicable law.

     In connection with the obligations of the Company with respect to the Shelf Registration, the Company shall:

     (a) at a reasonable time prior to filing the Shelf Registration Statement, any Prospectus forming a part thereof, any amendment to the Shelf Registration Statement or amendment or supplement to such Prospectus (other than amendments and supplements that do nothing more than name Holders and provide information with respect thereto), furnish to the Purchasers or any Underwriter or designee thereof and one special counsel to the Purchasers or any Underwriter or designee thereof copies of all such documents proposed to be filed and use its reasonable efforts to address in each such document when so filed with the SEC such comments as the Purchasers or any Underwriter or designee thereof and such special counsel to the Purchasers or any Underwriter or designee thereof reasonably shall propose within three (3) Business Days of the delivery of such copies to the Purchasers or any Underwriter or designee thereof and counsel to the Purchaser or any Underwriter or designee thereof. In addition, if any Holder that has provided the Questionnaire and the other information required by Section (c) shall so request in writing, a

     (c) Notifications and Other Indemnification Procedures. Promptly after receipt by an indemnified party under this Section 4 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 4, notify the indemnifying party in writing of the commencement thereof, but the failure to so notify the indemnifying party (1) will not relieve it from liability under paragraph (a), (b) or (c) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (2) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a), (b) or (c) above. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 4 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (other than local counsel), reasonably approved by the indemnifying party, representing the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party.

     (d) Settlements. The indemnifying party under this Section 4 shall not be liable for any settlement of any proceeding effected without its written consent, which shall not be withheld unreasonably, but if settled with such consent or if there is a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by Section (c) hereof, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have

C:\DOCUME~1\LANCAS~1\LOCALS~1\Temp\BCL Technologies\easyPDF 4\@BCL@440B5B9C\@ ***@***

     EXECUTION COPY received notice of the terms of such settlement at least 45 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (x) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (y) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

     (e) If the indemnification provided for in this Section 4 is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, in such proportion as is appropriate to reflect the relative fault of the Company on the one hand and the Holders on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

     The relative fault of the indemnifying parties on the one hand and the indemnified parties and the Purchasers on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company, or by the Holders and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

     The Company and the Holders agree that it would not be just and equitable if contribution pursuant to this Section 4 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 4. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 4 shall be deemed to include any reasonable out-of-pocket legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

     Notwithstanding the provisions of this Section 4, no Holder shall be required to indemnify or contribute any amount in excess of the amount by which the total price at which the Securities sold by such Holder 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.

     No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

In addition, under no circumstances shall the Company be required to commence a Sponsor Supported Distribution at any time during the three week period immediately preceding the scheduled public disclosure of results for any quarter (the “Pre-Announcement Periods”) and any delay during that time shall not be counted against the Suspension Period. If a request for a Sponsor Supported Distribution has been made before any Delay Period or Pre-Announcement Period, however, the Company will provide reasonable cooperation as is reasonably requested during such Delay Period or Pre-Announcement Period to permit such Sponsor Supported Distribution to be commenced promptly following the expiration of

     (c) To the extent the Shelf Registration Statement is effective and available for use at the time of any proposed sale or offer of any Securities by any Purchaser participating in such distribution, each such Purchaser agrees that the sale and offer of such Securities made by it shall be made pursuant to such effective Shelf Registration Statement such that the transferee of such Securities will receive unrestricted Securities; provided, that (i) transfers of Securities between the Sponsor Purchasers and the Bank Purchaser pursuant to the terms of any Swap Agreement, and (ii) transfers of Securities by the Bank Purchaser pursuant to its rights under Section 5(b) of a Swap Agreement upon a Swap Default or pursuant to the exercise of the Bank Purchaser’s rights under Section 7 of the Security Agreement in a transaction exempt from the registration requirements of the Securities Act and in accordance with the provisions of the applicable Indenture shall not be subject to this requirement.
