2. Registration Under the Securities Act.

(a) Except as set forth in Section 2(b) below, the Company agrees to file under the Securities Act, one or more registration statements relating to an offer to exchange (such registration statements, together, the “Exchange Registration Statement,” and such offer, the “Exchange Offer”) any and all of the Securities for a like aggregate principal amount of debt securities issued by the Company and guaranteed by the Guarantors, which debt securities and guarantees are substantially identical to the Securities and the related Guarantees, respectively (and are entitled to the benefits of a trust indenture which is substantially identical to the Indenture or is the Indenture and which has been qualified under the Trust Indenture Act), except that they have been registered pursuant to an effective registration statement under the Securities Act and do not contain provisions for Additional Interest contemplated in Section 2(d) below (such new debt securities hereinafter called “Exchange Securities”). The Company agrees to use all commercially reasonable efforts to cause the Exchange Registration Statement to become effective under the Securities Act no later than 360 days after the Issue 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. Unless the Exchange Offer would not be permitted by applicable law or Commission policy, the Company further agrees to use all commercially reasonable efforts to (i) commence the Exchange Offer promptly following the Effective Time of such Exchange Registration Statement, (ii) hold the Exchange Offer open for at least 20 Business Days in accordance with Regulation 14E promulgated by the Commission under the Exchange Act, or longer, if required by the federal securities laws and (iii) exchange Exchange Securities for all Registrable Securities that have been properly tendered and not withdrawn promptly following the expiration of the Exchange Offer. The Exchange Offer will be deemed to have been “completed” only if: (i) the Exchange Securities and related guarantees received by holders, other than Restricted Holders, in the Exchange Offer for Registrable Securities are, upon receipt, transferable by each such holder without restriction under the Securities Act and the Exchange Act and without material restrictions under the blue sky or securities laws of a substantial majority of the States of the United States of America and (ii) upon the Company having exchanged, pursuant to the Exchange Offer, Exchange Securities for all Registrable Securities that have been properly tendered and not withdrawn before the expiration of the Exchange Offer, which shall be on a date that is at least 20 Business Days following the commencement of the Exchange Offer. The Company agrees (x) to include in the Exchange Registration Statement a prospectus for use in any resales by any holder of Exchange Securities that is a broker-dealer and (y) to keep such Exchange Registration Statement effective for a period (the “Resale Period”) beginning when Exchange Securities are first issued in the Exchange Offer and ending upon the earlier of the expiration of the 90^th day after the Exchange Offer has been completed or such time as such broker-dealers no longer own any Registrable Securities. With respect to such Exchange Registration Statement, such holders shall have the benefit of the rights of indemnification and contribution set forth in Subsections 6(a), (e), (f) and (g).

(b) If (i) on or prior to the time the Exchange Offer is completed, existing law or 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 by the earlier of the 60th Business Day after the Effective Time of the Exchange Registration Statement relating to the Exchange Offer or the 360th day following the Issue Date (provided, that the Company’s failure to complete the Exchange Offer by the deadline set forth in this Section 2(b)(ii) shall be considered a Registration Default for which Additional Interest shall be payable pursuant to Section 2(d) hereof until such time as a Shelf Registration Statement covering resales of the Registrable Securities has become or is declared effective) or (iii) any holder of Registrable Securities notifies the Company prior to the 20^th Business Day following the completion of the Exchange Offer that: (A) it is prohibited by law or Commission policy

from participating in the Exchange Offer, (B) it may not resell the Exchange Securities to the public without delivering a prospectus and the prospectus supplement contained in the Exchange Registration Statement is not appropriate or available for such resales or (C) it is a broker-dealer and owns Securities acquired directly from the Company or an affiliate of the Company, then the Company and the Guarantors 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 no later than 30 days after the time such obligation to file arises (but no earlier than 360 days after the Issue Date) one or more “shelf” registration statements 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 statements, the “Shelf Registration Statement”). The Company agrees to use all commercially reasonable efforts to cause the Shelf Registration Statement to become or be declared effective no later than 90 days after such Shelf Registration Statement filing obligation arises (but no earlier than 360 days after the Issue Date); provided that if at any time the Company is or becomes a “well-known seasoned issuer” (as defined in Rule 405) and is eligible to file an “automatic shelf registration statement” (as defined in Rule 405), then the Company and the Guarantors shall file the Exchange Registration Statement in the form of an automatic shelf registration statement as provided in Rule 405. The Company agrees to use all commercially reasonable efforts to keep such Shelf Registration Statement continuously effective until the earlier of the second anniversary of the Effective Time or such time as there are no longer any Registrable Securities outstanding. 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. The Company agrees, after the Effective Time of the Shelf Registration Statement and promptly upon the request of any holder of Registrable Securities that is not then an Electing Holder, to use all commercially reasonable efforts 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 (whether by post-effective amendment thereto or by filing a prospectus pursuant to Rules 430B and 424(b) under the Securities Act identifying such holder); provided, however, that nothing in this sentence shall (A) 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) or (B) require the Company or the Guarantors to file more than one post-effective amendment to the Shelf Registration Statement in any 45-day period. Notwithstanding anything to the contrary in this Section 2(b), upon notice to the Electing Holders, the Company may suspend the use or the effectiveness of such Shelf Registration Statement, or extend the time period in which it is required to file the Shelf Registration Statement for one or more periods up to 90 days in the aggregate in any 12-month period (each, a “Suspension Period”) if the Board of Directors of the Company determines that there is a valid business purpose for suspension of the Shelf Registration Statement; provided that the Company shall promptly notify the Electing Holders when the Shelf Registration Statement may once again be used or is effective.

(c) For the sole benefit of each Market Maker or any of their affiliates (as defined under the rules and regulations of the Commission), so long as (x) any of the Registrable Securities are outstanding and (y) it would be necessary under applicable laws, rules and regulations, in the reasonable opinion of any Market Maker, for such Market Maker or any of its affiliates to deliver a prospectus in connection with market-making activities with respect to the Registrable Securities or Exchange Securities and such Market Maker or such affiliate proposes to make a market in the Registrable Securities or Exchange Securities as part of its business in the ordinary course (the “Market-Making Conditions”), the following provisions shall apply for the sole benefit of each Market Maker and its affiliates (it being understood that only a person for whom the Market-Making Conditions apply at the applicable time shall be entitled to the use of a Market Making Shelf Registration Statement and related provisions of this Agreement), the Company shall use all commercially reasonable efforts to file under

the Securities Act, a “shelf” registration statement (which may be the Exchange Registration Statement or the Shelf Registration Statement if permitted by the rules and regulations of the Commission) pursuant to Rule 415 under the Securities Act or any similar rule that may be adopted by the Commission providing for the registration of, and the sale on a continuous or delayed basis in secondary transactions by each Market Maker of, Securities (in the event of a Shelf Registration) or Exchange Securities (in the event of an Exchange Offer) (such filing, the “Market Making Shelf Registration,” and such registration statement, the “Market Making Shelf Registration Statement”). The Company agrees to use all commercially reasonable efforts to cause the Market Making Shelf Registration Statement to become or be declared effective on or prior to (i) the date the Exchange Offer is completed pursuant to Section 2(a) above or (ii) the date the Shelf Registration becomes or is declared effective pursuant to Section 2(b) above, and to keep such Market Making Shelf Registration Statement continuously effective for so long as any Market Maker may be required to deliver a prospectus in connection with transactions in the Securities or the Exchange Securities, as the case may be. In the event that a Market Maker holds Securities at the time an Exchange Offer is to be conducted under Section 2(a) above, the Company agrees that the Market Making Shelf Registration shall provide for the resale by such Market Maker of such Securities and shall use its commercially reasonable efforts to keep the Market Making Shelf Registration Statement continuously effective until such time as such Market Maker determines in its reasonable judgment that it is no longer required to deliver a prospectus in connection with the sale of such Securities.

Notwithstanding anything to the contrary in this Section 2(c), upon at least 10 Business Days prior written notice to each Market Maker, the Company may elect to cause the Market Making Registration Statement to provide for the registration of, and the sale on a continuous or delayed basis in secondary transactions by any Affiliate Investor of Securities (in the event of a Shelf Registration) or Exchange Securities (in the event of an Exchange Offer) regardless of whether such Affiliate Investor otherwise would qualify as an Electing Holder eligible to participate in a Shelf Registration Statement in accordance with Section 2(b) hereof; provided however, if any Market Maker requests in writing at any time that the Company exclude any or all Affiliate Investors from the Market Making Registration Statement, then the Company shall either omit such Affiliate Investors from inclusion in the Market Making Registration Statement or promptly amend the Market Making Registration Statement to exclude them from the Market Making Registration Statement. The inclusion of any Affiliate Investor in the Market Making Registration Statement shall not affect the rights of any Market Maker to make any determinations otherwise provided exclusively to each Market Maker in this Agreement.

Notwithstanding the foregoing, the Company may suspend the offering and sale under the Market Making Shelf Registration Statement for one or more Suspension Periods if the Board of Directors of the Company determines that such registration would require (i) disclosure of an event at such time as could reasonably be expected to have a material adverse effect on the business operations or prospects of the Company (ii) disclosure of material information relating to a corporate development or (iii) such Market-Making Registration Statement or amendment or supplement thereto contains an untrue statement of material fact or omits to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading; provided that the Company shall promptly notify each Market Maker when the Market Making Shelf Registration Statement may once again be used.

(d) In the event that (i) the Company and the Guarantors have not filed the Exchange Registration Statement or the Shelf Registration Statement on or before the date on which such registration statement is required to be filed pursuant to Section 2(a) or Section 2(b), as applicable, or (ii) such Exchange Registration Statement or Shelf Registration Statement has not become effective or been 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 Section 2(b), as applicable, or (iii) the Exchange Offer has not been completed by the earlier of the 60^th Business Day after the Effective Time of the Exchange Registration Statement relating to the Exchange Offer or the 360th day following the Issue Date (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 Section 2(b) 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, including with respect to any Shelf Registration Statement, during any applicable Suspension Period in accordance with the last sentence of Section 2(b)) without being succeeded immediately by an additional registration statement 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, subject to the provisions of Section 9(b), additional interest (“Additional Interest”), in addition to the Base Interest, shall accrue on the outstanding principal amount of the Registrable Securities at a per annum rate of 0.25% for the first 90 days of the Registration Default Period and at a per annum rate of 0.50% thereafter for the remaining portion of the Registration Default Period. Additional Interest shall accrue and be payable only with respect to a single Registration Default at any given time, notwithstanding the fact that multiple Registration Defaults may exist at such time. The accrual of Additional Interest shall be the exclusive monetary remedy available to the holders of Registrable Securities for any Registration Default.

(e) The Company shall take, and shall cause the Guarantors to take, all actions necessary or advisable to be taken by them to ensure that the transactions contemplated herein are effected as so contemplated, including all actions necessary or desirable to register the Guarantees under the registration statement contemplated in Section 2(a), Section 2(b) or Section 2(c), as applicable.

(f) Any reference herein to a registration statement as of any time shall be deemed to include any document incorporated, or deemed to be incorporated, therein by reference as of such time and any reference herein to any post-effective amendment to a registration statement as of any time shall be deemed to include any document incorporated, or deemed to be incorporated, therein by reference as of such time.

3. Registration Procedures.

If the Company and the Guarantors file a registration statement pursuant to Section 2(a), Section 2(b) or Section 2(c) the following provisions shall apply:

(a) At or before the Effective Time of the Exchange Registration, the Shelf Registration or the Market Making Registration, whichever may be first, the Company shall qualify the Indenture under the Trust Indenture Act.

The Company may require, as a condition to including any Securities or Exchange Securities in the Market Making Shelf Registration Statement filed pursuant to Section 2(c) hereof and to entering into any underwriting agreement with respect thereto, that the Company shall have received an undertaking reasonably satisfactory to it from each underwriter named in any such underwriting agreement, severally and not jointly, to, and each Market Maker shall, and hereby agrees to, (i) indemnify and hold harmless the Company and the Guarantors against any losses, claims, damages or liabilities to which the Company or the Guarantors may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Market Making Shelf Registration Statement, or any preliminary, final or summary prospectus contained therein or furnished by the Company to the Market Makers or to any such underwriter, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by such Market Maker or such underwriter expressly for use therein, which information, with respect to information provided by any Market Maker for inclusion in the prospectus forming a part of the Market Making Registration Statement the parties hereto agree will be limited to the statements concerning the market-making activities of the Market Makers to be set forth on the cover page and in the “Plan of Distribution” section of the prospectus forming a part of the Market Making Shelf Registration Statement and in the analogous section of the Canadian wrapper, if any, of such prospectus and (ii) reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that, in the case of Securities held by any Market Maker at the time of the Exchange Offer, no Market Maker shall be required to undertake liability to any person under this Section 6(c) for any amounts in excess of the dollar amount of the proceeds to be received by such Market Maker from the sale of such Securities by such Market Maker pursuant to the Market Making Shelf Registration.

(d) Indemnification by Affiliate Investors in Connection with the Market Making Shelf Registration. The Company may require, as a condition to including any Securities or Exchange Securities in the Market Making Shelf Registration Statement filed pursuant to Section 2(d) hereof and to entering into any underwriting agreement with respect thereto, that the Company shall have received an undertaking reasonably satisfactory to it from each underwriter named in any such underwriting agreement, severally and not jointly, to, and each Affiliate Investor shall, and hereby agrees to, (i) indemnify and hold harmless the Company and the Guarantors against any losses, claims, damages or liabilities to which the Company or the Guarantors may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Market Making Shelf Registration Statement, or any preliminary, final or summary prospectus contained therein or furnished by the Company to such Affiliate Investor or to any such underwriter, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by such Affiliate Investor or such underwriter expressly for use therein, and (ii) reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that, in the case of Securities held by any Market Maker at the time of the Exchange Offer, no Market Maker shall be required to

undertake liability to any person under this Section 6(d) for any amounts in excess of the dollar amount of the proceeds to be received by such Market Maker from the sale of such Securities by such Market Maker pursuant to the Market Making Shelf Registration.

(e) Notices of Claims, Etc. Promptly after receipt by an indemnified party under subsection (a), (b), (c) or (d) above of written notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party pursuant to the indemnification provisions of or contemplated by this Section 6, notify such indemnifying party in writing of the commencement of such action; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under the indemnification provisions of or contemplated by Section 6(a), 6(b), 6(c) or 6(d). In case any such action shall be brought against any indemnified party and it shall notify an indemnifying party of the commencement thereof, such indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, such indemnifying party shall not be liable to such indemnified party for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the prior written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) 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.

(f) Contribution. If for any reason the indemnification provisions contemplated by Section 6(a), 6(b), 6(c) or 6(d) are unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative fault of such indemnifying party and indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by such indemnifying party or by such indemnified party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this Section 6(f) 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 this Section 6(f). The amount paid or payable by an indemnified party as a result of the losses, claims, damages, or liabilities (or actions in respect thereof) referred to above shall be deemed to include 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 Section 6(f), none of any holder, Affiliate Investor or, in the case of a Market Making Shelf Registration relating to the sale by any Market Maker of Securities held by it at the time of the Exchange Offer, such Market Maker, shall be required to contribute any amount in excess of the amount by which the dollar amount of the proceeds received by such holder from the sale of any

Registrable Securities or such Market Maker or any Affiliate Investor from the sale of any such Securities (after deducting any fees, discounts and commissions applicable thereto) exceeds the amount of any damages which such holder or such Market Maker or such Affiliate Investor, as applicable, have 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’, Market Maker’s and any Affiliate Investor’s obligations in this Section 6(f) to contribute shall be several in proportion to the principal amount of Registrable Securities registered by them and not joint.

(g) The obligations of the Company and the Guarantors under this Section 6 shall be in addition to any liability which the Company or the Guarantors may otherwise have and shall extend, upon the same terms and conditions, to each officer, director and partner of each Market Maker, each holder, Electing Holder, Affiliate Investor, and each person, if any, who controls any Market Maker, any holder, Electing Holder, Affiliate Investor within the meaning of the Securities Act; and the obligations of the Market Makers, the holders, the Electing Holders, the Affiliate Investors contemplated by this Section 6 shall be in addition to any liability which the Market Makers, the respective holder or Affiliate Investor may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company or any of the Guarantors (including any person who, with his consent, is named in any registration statement as about to become a director of the Company or any of the Guarantors) and to each person, if any, who controls the Company within the meaning of the Securities Act.

7. Underwritten Offerings.

Each holder of Registrable Securities hereby agrees with the Company and each other such holder that no holder of Registrable Securities may participate in any underwritten offering hereunder unless (a) the Company gives its prior written consent to such underwritten offering, (b) the managing underwriter or underwriters thereof shall be designated by Electing Holders holding at least a majority in aggregate principal amount of the Registrable Securities to be included in such offering, provided that such designated managing underwriter or underwriters is or are reasonably acceptable to the Company, (c) each holder of Registrable Securities participating in such underwritten offering agrees to sell such holder’s Registrable Securities on the basis provided in any underwriting arrangements approved by the persons entitled hereunder to approve such arrangements and (d) each holder of Registrable Securities participating in such underwritten offering completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements.

8. Rule 144.

The Company covenants to the holders of Registrable Securities, the Market Makers or any Affiliate Investor that to the extent it shall be required to do so under the Exchange Act, the Company shall timely file the reports required to be filed by it under the Exchange Act or the Securities Act (including the reports under Sections 13 and 15(d) of the Exchange Act referred to in subparagraph (c)(1) of Rule 144), and shall take such further action as any holder of Registrable Securities, any Market Maker or any Affiliate Investor may reasonably request, all to the extent required from time to time to enable such holder to sell Registrable Securities or any Market Maker or any Affiliate Investor to sell Securities or Exchange Securities without registration under the Securities Act within the limitations of the exemption provided by Rule 144. Upon the request of any holder of Registrable Securities, any Market Maker or any Affiliate Investor in connection with that holder’s, that Market Maker’s or that Affiliate Investor’s sale pursuant to Rule 144, the Company shall deliver to such holder, such Market Maker or such Affiliate Investor a written statement as to whether it has complied with such requirements.

9. Miscellaneous.

(a) No Inconsistent Agreements. The Company and the Guarantors represent, warrant, covenant and agree that they have not granted, and shall not grant, registration rights with respect to Registrable Securities, Securities or Exchange Securities, as applicable, or any other securities which would be inconsistent with the terms contained in this Agreement.

(b) Specific Performance. The parties hereto acknowledge that there would be no adequate remedy at law if the Company or any of the Guarantors fails to perform any of their respective obligations hereunder and that the Lenders and the holders from time to time of the Registrable Securities may be irreparably harmed by any such failure, and accordingly agree that the Lenders and such holders, in addition to any other remedy to which they may be entitled at law or in equity, shall be entitled to compel specific performance of the obligations of the Company and the Guarantors under this Agreement in accordance with the terms and conditions of this Agreement, in any court of the United States or any State thereof having jurisdiction. Time shall be of the essence in this Agreement.

(c) Notices. All notices, requests, claims, demands, waivers and other communications hereunder shall be in writing and shall be deemed to have been duly given when delivered by hand, if delivered personally, by facsimile or by courier, or three days after being deposited in the mail (registered or certified mail, postage prepaid, return receipt requested) as follows: If to the Company, to it at Energy Plaza, 0000 Xxxxx Xxxxxx, Xxxxxx, Xxxxx 00000-0000, Attention: General Counsel and if to a holder, to the address of such holder set forth in the security register or other records of the Company, or to such other address as the Company or any such holder may have furnished to the other in writing in accordance herewith, except that notices of change of address shall be effective only upon receipt.

(d) Parties in Interest. All the terms and provisions of this Agreement shall be binding upon, shall inure to the benefit of and shall be enforceable by the parties hereto and the holders from time to time of the Registrable Securities and the respective successors and assigns of the parties hereto and such holders. In the event that any transferee of any holder of Registrable Securities shall acquire Registrable Securities, in any manner, whether by gift, bequest, purchase, operation of law or otherwise, such transferee shall, without any further writing or action of any kind, be deemed a beneficiary hereof for all purposes and such Registrable Securities shall be held subject to all of the terms of this Agreement, and by taking and holding such Registrable Securities such transferee shall be entitled to receive the benefits of, and be conclusively deemed to have agreed to be bound by all of the applicable terms and provisions of this Agreement. If the Company shall so request, any such successor, assign or transferee shall agree in writing to acquire and hold the Registrable Securities subject to all of the applicable terms hereof.

(e) Survival. The respective indemnities, agreements, representations, warranties and each other provision set forth in this Agreement or made pursuant hereto shall remain in full force and effect regardless of any investigation (or statement as to the results thereof) made by or on behalf any Market Maker, any Affiliate Investor or any holder of Registrable Securities, any director, officer or partner of such Market Maker, such Affiliate Investor or such holder, or any controlling person of any of the foregoing, and shall survive delivery of and payment for the Registrable Securities pursuant to the Loan Agreement and the transfer and registration of Registrable Securities by such holder or of Securities or Exchange Securities by any Market Maker or any Affiliate Investor and the consummation of an Exchange Offer.

(f) Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

Each holder of any Registrable Securities at the time or thereafter outstanding shall be bound by any amendment or waiver effected pursuant to this Section 9(h), whether or not any notice, writing or marking indicating such amendment or waiver appears on such Registrable Securities or is delivered to such holder.

(i) Inspection. For so long as this Agreement shall be in effect, this Agreement and a complete list of the names and addresses of all the holders of Registrable Securities and the address of each Market Maker and each Affiliate Investor shall be made available for inspection and copying on any Business Day by any Market Maker, any Affiliate Investor or any holder of Registrable Securities for proper purposes only (which shall include any purpose related to the rights of the holders of Registrable Securities under the Securities, the Indenture and this Agreement) at the offices of the Company at the address thereof set forth in Section 9(c) and at the office of the Trustee under the Indenture.

(j) Counterparts. This Agreement may be executed by the parties in counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument.

(k) Severability.

In addition, the undersigned, by signing and returning this Notice and Questionnaire, represents and warrants that the representation set forth in Section 3(h) of the Registration Rights Agreement is true and correct as of the date hereof.

	(b)	Set forth below is Interpretation A.65 of the Commission’s July 1997 Manual of Publicly Available Interpretations regarding short selling:

		“An issuer filed a Form S-3 registration statement for a secondary offering of common stock which is not yet effective. One of the selling shareholders wanted to do a short sale of common stock “against the box” and cover the short sale with registered shares after the effective date. The issuer was advised that the short sale could not be made before the registration statement becomes effective, because the shares underlying the short sale are deemed to be sold at the time such sale is made. There would, therefore, be a violation of Section 5 if the shares were effectively sold prior to the effective date.”

		By returning this Notice and Questionnaire, the undersigned Selling Securityholder will be deemed to be aware of the foregoing interpretation.
