(d) Each Holder hereby acknowledges and agrees that any Broker-Dealer and any such Holder using the Registered Exchange Offer to participate in a distribution of the New Securities (x) could not under Commission policy as in effect on the date of this Agreement rely on the position of the Commission in ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ and Co., Inc. (pub. avail. June 5, 1991) and Exxon Capital Holdings Corporation (pub. avail. May 13, 1988) and Shearman & Sterling (July 2, 1993) and similar no-action letters; and (y) must comply with the registration and prospectus delivery requirements of the Act in connection with any secondary resale transaction which must be covered by an effective registration statement containing the selling security holder information required by Item 507 or 508, as applicable, of Regulation S-K under the Act if the resales are of New Securities obtained by such Holder in exchange for Securities acquired by such Holder directly from the Company or one of its Affiliates. Accordingly, as a condition to its participation in the Registered Exchange Offer, each Holder participating in the Registered Exchange Offer shall be required to represent to the Company in the Letter of Transmittal relating to the Registered Exchange Offer or by other means that, at the time of the consummation of the Registered Exchange Offer:

(i) any New Securities received by such Holder will be acquired in the ordinary course of business;

an unsold allotment, at the request of such Purchaser, the Company shall issue and deliver to such Purchaser or the Person purchasing New Securities registered under a Shelf Registration Statement as contemplated by Section 3 hereof from such Purchaser, in exchange for such Securities, a like principal amount of New Securities. The Company shall use its reasonable best efforts to cause the CUSIP Service Bureau to issue the same CUSIP number for such New Securities as for New Securities issued pursuant to the Registered Exchange Offer.

3. Shelf Registration. If (A): (i) due to any change in law or applicable interpretations thereof by the Commission’s staff, the Company determines upon advice of its outside counsel that it is not permitted to effect the Registered Exchange Offer as contemplated by Section 2 hereof, or (ii) for any other reason the Registered Exchange Offer is not consummated within 30 Business Days (or such longer period as required by applicable law) of the Effectiveness Target Date (or, if such 30th Business Day is not a Business Day, the next succeeding Business Day) or the Exchange Offer Registration Statement is not declared effective within 180 days of the Issue Date (or if such 180^th day is not a Business Day, the next succeeding Business Day); or (B) any Holder of Transfer Restricted Securities notifies the Company prior to the 20^th day following the consummation of the Registered Exchange Offer that: (i) it is prohibited by law or policy of the Commission from participating in the Registered Exchange Offer; (ii) it may not resell the New Securities acquired by it in the Registered Exchange Offer to the public without delivering a prospectus and the prospectus contained in the Registered Exchange Offer is not appropriate or available for such resales or (iii) that it is a Broker-Dealer and owns Securities acquired directly from the Company or an affiliate of the Company, the Company shall effect a Shelf Registration Statement in accordance with subsection (b) below.

(a) (i) The Company shall as promptly as practicable (but in no event more than 30 days after so required or requested pursuant to this Section 3 (or, if such 30^th day is not a Business Day, the next succeeding Business Day)), use its reasonable best efforts to file with the Commission and thereafter (but in no event more than 90 days after the date the Company was required or requested to make such filing pursuant to this Section 3 (or, if such 90^th day is not a Business Day, the next succeeding Business Day)) use its reasonable best efforts to cause to be declared effective under the Act a Shelf Registration Statement relating to the offer and sale of the Securities or the New Securities, as applicable, by the Holders thereof from time to time in accordance with the methods of distribution elected by such Holders and set forth in such Shelf Registration Statement; provided, however, that no Holder (other than a Purchaser) shall be entitled to have the Securities held by it covered by such Shelf Registration Statement unless such Holder agrees in writing to be bound by all of the provisions of this Agreement applicable to such Holder; and provided further, that with respect to New Securities received by a Purchaser in exchange for Securities constituting any portion of an unsold allotment, the Company may, if permitted by current interpretations by the Commission’s staff, file a post-effective amendment to the Exchange Offer Registration Statement containing the information required by Item 507 or 508 of Regulation S-K, as applicable, in satisfaction of its obligations under this subsection with respect thereto, and any such Exchange Offer Registration Statement, as so amended, shall be referred to herein as, and governed by the provisions herein applicable to, a Shelf Registration Statement. Notwithstanding anything in this Section 3, Additional Interest shall accrue only in accordance with the provisions of Section 6 hereof.

(ii) The Company shall use its reasonable best efforts to keep the Shelf Registration Statement continuously effective, supplemented and amended as required by the Act, in order to permit the Prospectus forming part thereof to be usable by Holders from the date the Shelf Registration Statement is declared effective by the Commission until the earlier of: (i) such date as all the Securities covered by the Shelf Registration Statement have been sold, or (ii) the date on which all of the Securities held by persons that are not Affiliates of the Company may be resold without registration pursuant to Rule 144(k) under the Act (such period being called the “Shelf Registration Period”). The Company shall be deemed not to have used its reasonable best efforts to keep the Shelf Registration Statement effective during the requisite period if it voluntarily takes any action that would result in Holders of Securities covered thereby not being able to offer and sell such Securities during that period, unless (A) such action is required by applicable law; or (B) such action is taken by the Company in good faith and for valid business reasons (not including avoidance of the Company’s obligations hereunder), including the acquisition or divestiture of assets, a merger or financing so long as the Company promptly thereafter complies with the requirements of Section 4(k) hereof, if applicable.

(b) Not less than 30 days prior to the Effective Time of any Shelf Registration Statement required under this Agreement, the Company shall mail the Notice and Questionnaire (the “Notice and Questionnaire”) substantially in the form attached as Annex E hereto to the Holders of Transfer Restricted Securities; no Holder shall be entitled to be named as a selling securityholder in the Shelf Registration Statement as of the Effective Time, and no Holder shall be entitled to use the prospectus forming a part thereof for resales of Securities at any time, unless such Holder has returned a completed and signed Notice and Questionnaire to the Company by the deadline for response set forth therein; provided, however, that holders of Transfer Restricted Securities shall have at least 28 days from the date on which the Notice and Questionnaire is first mailed to such Holders to return a completed and signed Notice and Questionnaire to the Company.

(c) After the Effective Time of any Shelf Registration Statement required to be filed under this Agreement, Holders of Transfer Restricted Securities who did not timely return a Notice and Questionnaire to the Company may return a Notice and Questionnaire at any time and may request to be included in such Shelf Registration Statement. If:

(i) the Company can include such Holder with respect to its Transfer Restricted Securities by means of a prospectus supplement filed pursuant to Rule 424(b) of the Act or by means of a registration statement filed pursuant to Rule 462(b) of the Act, then the Company shall file such Rule 424(b) supplement or Rule 462(b) registration statement with the Commission within 10 Business Days of its receipt of the Notice and Questionnaire;

(ii) the Company, in the opinion of its counsel, cannot include such Holder with respect to its Transfer Restricted Securities by means of a prospectus supplement to the prospectus contained as part of such effective Shelf Registration Statement or by means of a related registration statement filed pursuant to Rule 462(b) of the Act, the Company shall promptly take any action reasonably necessary to enable such a Holder to use a registration statement for resale of Transfer Restricted Securities,

including, without limitation, any action necessary to identify such Holders or selling securityholder in a post-effective amendment to the Shelf Registration Statement or new Shelf Registration Statement which the Company shall promptly file and cause to be declared effective to cover the resale of the Transfer Restricted Securities that are the subject of such request. If the Company is required to file such post-effective amendment to the Shelf Registration Statement or a new Shelf Registration Statement for the sole purpose of adding Holders to the Shelf Registration Statement, the Company shall not be required to file such post-effective amendment or new Shelf Registration Statement more frequently than once every 30 days.

(d) In the event of a Shelf Registration Statement, in addition to the information required to be provided in the Notice and Questionnaire, the Company may require Holders to furnish to the Company additional information regarding such Holder and such Holder’s intended method of distribution of Securities as may be required in order to comply with the Securities Act. Each Holder agrees to notify the Company as promptly as practicable of any inaccuracy or change in information previously furnished by such Holder to the Company or of the occurrence of any event in either case as a result of which any prospectus relating to the Shelf Registration Statement contains or would contain an untrue statement of a material fact regarding such Holder or such Holder’s intended method of disposition of such Securities or omits to state any material fact regarding such Holder or such Holder’s intended method of disposition of such Securities required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing, and promptly to furnish to the Company any such required additional information so that such prospectus shall not contain, with respect to such Holder or the disposition of such Securities, an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing.

Each Holder of Securities agrees by acquisition of such Securities that, upon actual receipt of any notice from the Company of the happening of any event of the kind described in Section 4(c)(ii), (iii), (iv), and (v) hereof, such Holder will forthwith discontinue any and all dispositions of such Securities by means of the Registration Statement or Prospectus until such Holder’s receipt of the copies of the supplemented or amended Prospectus contemplated by Section 4(b), or until it is advised in writing (the “Advice”) by the Company that the use of the applicable Prospectus may be resumed, and has received copies of any amendments or supplements thereto provided, however, that this paragraph shall not prohibit any Holder from engaging in dispositions of the Securities through means other than pursuant to the Registration Statement or Prospectus, as long as such dispositions comply with applicable laws.

(d) The Company shall use its reasonable best efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement or the qualification of the securities therein for sale in any jurisdiction at the earliest possible time.

(e) The Company shall furnish, upon written request, to each Holder of Securities covered by any Shelf Registration Statement, without charge, at least one copy of such Shelf Registration Statement and any post-effective amendment thereto, including all material incorporated therein by reference and, if requested, all exhibits thereto (including exhibits incorporated by reference therein).

(i) Prior to the Registered Exchange Offer or any other offering of Securities pursuant to any Registration Statement, the Company shall arrange, if necessary, for the qualification of the Securities or the New Securities for sale under the laws of such jurisdictions as any Holder shall reasonably request and will maintain such qualification in effect so long as required; provided that in no event shall the Company be obligated to qualify to do business in any jurisdiction where it is not then so qualified or to take any action that would subject it to service of process in suits, other than those arising out of the Initial Placement, the Registered Exchange Offer or any offering pursuant to a Shelf Registration Statement, in any such jurisdiction where it is not then so subject or otherwise subject itself to taxation in any such jurisdiction.

(m) Not later than the effective date of any Registration Statement, the Company shall provide CUSIP numbers for the Securities or the New Securities, as the case may be, registered under such Registration Statement and provide the Trustee with printed certificates for such Securities or New Securities, in a form eligible for deposit with The Depository Trust Company.

(n) The Company shall comply with all applicable rules and regulations of the Commission and shall make generally available to its security holders no later than 45 days after the end of any 12-month period (or 90 days after the end of any 12-month period if such period is a fiscal year), an earnings statement satisfying the provisions of Section 11(a) of the Act and Rule 158 thereunder (or any similar rule under the Act) for a period of at least 12 months beginning on the first day of the first fiscal quarter after the effective date of the applicable Registration Statement.

(o) The Company shall cause the Indenture to be qualified under the Trust Indenture Act in a timely manner;

(p) The Company may require each Holder of securities to be sold pursuant to any Shelf Registration Statement to furnish to the Company such information regarding the Holder and the distribution of such securities as the Company may from time to time reasonably require for inclusion in such Registration Statement.

(q) In the case of any Shelf Registration Statement, the Company shall enter into such agreement and take all other appropriate actions (including if requested an underwriting agreement in customary form) in order to expedite or facilitate the registration or the disposition of the Securities, and in connection therewith, if an underwriting agreement is entered into, cause the same to contain indemnification provisions and procedures no less favorable than those set forth in Section 7 (or such other provisions and procedures acceptable to the Majority Holders and the Managing Underwriters, if any, with respect to all parties to be indemnified pursuant to Section 7).

(r) In the case of any Shelf Registration Statement, the Company shall:

(i) make reasonably available for inspection by the representatives or agents of the Holders of Securities designated by the Majority Holders to be registered thereunder, any underwriter participating in any disposition pursuant to such Registration Statement, and any attorney, accountant or other agent retained by the Holders or any

(iii) make such representations and warranties to the Holders of Securities registered thereunder and the underwriters, if any, in form, substance and scope as are customarily made by issuers to underwriters in primary underwritten offerings and covering matters including, but not limited to, those set forth in the Purchase Agreement;

(iv) obtain opinions of counsel to the Company and updates thereof (which counsel and opinions (in form, scope and substance) shall be reasonably satisfactory to the Managing Underwriters, if any) addressed to each selling Holder and the underwriters, if any, covering such matters as are customarily covered in opinions requested in underwritten offerings and such other matters as may be reasonably requested by such Holders and underwriters;

(v) obtain “cold comfort” letters and updates thereof from the independent certified public accountants of the Company (and, if necessary, any other independent certified public accountants of any subsidiary of the Company or of any business acquired by the Company for which financial statements and financial data are, or are required to be, included in the Registration Statement), addressed to each selling Holder of Securities registered thereunder and the underwriters, if any, who have provided such accountants with a representation letter if required to do so under Statement on Auditing Standards No. 72 in customary form and covering matters of the type customarily covered in “cold comfort” letters in connection with primary underwritten offerings;

(vi) deliver such documents and certificates as may be reasonably requested by the Majority Holders and the Managing Underwriters, if any, including those to evidence compliance with Section 4(k) and with any customary conditions contained in the underwriting agreement or other agreement entered into by the Company; and

The actions set forth in clauses (iii), (iv), (v) and (vi) of this Section shall be performed at (A) the effectiveness of such Registration Statement and each post-effective amendment thereto; and (B) each closing under any underwriting or similar agreement as and to the extent required thereunder.

(s) In the case of any Exchange Offer Registration Statement, the Company shall:

(i) make reasonably available for inspection by each Purchaser, and any attorney, accountant or other agent retained by such Purchaser, all relevant financial and other records, pertinent corporate documents and properties of the Company and its subsidiaries;

(ii) cause the Company’s officers, directors and employees to supply all relevant information reasonably requested by such Purchaser or any such attorney, accountant or agent in connection with any such Registration Statement as is customary for similar due diligence examinations; provided, however, that any information that is designated in writing by the Company, in good faith, as confidential at the time of delivery of such information shall be kept confidential by such Purchaser or any such attorney, accountant or agent, unless such disclosure is made in connection with a court proceeding or required by law, or such information becomes available to the public generally or through a third party without an accompanying obligation of confidentiality;

(iii) make such representations and warranties to such Purchaser, in form, substance and scope as are customarily made by issuers to underwriters in primary underwritten offerings and covering matters including, but not limited to, those set forth in the Purchase Agreement;

(iv) obtain opinions of counsel to the Company and updates thereof (which counsel and opinions (in form, scope and substance) shall be reasonably satisfactory to such Purchaser and its counsel) addressed to such Purchaser, covering such matters as are customarily covered in opinions requested in underwritten offerings and such other matters as may be reasonably requested by such Purchaser or its counsel;

Purchaser, in customary form and covering matters of the type customarily covered in “cold comfort” letters in connection with primary underwritten offerings as permitted by Statement on Auditing Standards No. 72, or if requested by such Purchaser or its counsel in lieu of a “cold comfort” letter, an agreed-upon procedures letter under Statement on Auditing Standards No. 35, covering matters requested by such Purchaser or its counsel; and

(vi) deliver such documents and certificates as may be reasonably requested by such Purchaser or its counsel, including those to evidence compliance with Section 4(k) and with conditions customarily contained in underwriting agreements.

The foregoing actions set forth in clauses (iii), (iv), (v) and (vi) of this Section shall be performed at the close of the Registered Exchange Offer and the effective date of any post-effective amendment to the Exchange Offer Registration Statement.

(t) If a Registered Exchange Offer is to be consummated, upon delivery of the Securities by Holders to the Company (or to such other Person as directed by the Company) in exchange for the New Securities, the Company shall ▇▇▇▇, or caused to be marked, on the Securities so exchanged that such Securities are being canceled in exchange for the New Securities. In no event shall the Securities be marked as paid or otherwise satisfied.

(u) The Company will use its reasonable best efforts (i) if the Securities have been rated prior to the initial sale of such Securities, to confirm such ratings will apply to the Securities or the New Securities, as the case may be, covered by a Registration Statement; or (ii) if the Securities were not previously rated, to cause the Securities covered by a Registration Statement to be rated with at least one nationally recognized statistical rating agency, if so requested by Majority Holders with respect to the related Registration Statement or by any Managing Underwriters.

(v) In the event that any Broker-Dealer shall underwrite any Securities or participate as a member of an underwriting syndicate or selling group or “assist in the distribution” (within the meaning of the Rules of Fair Practice and the By-Laws of the NASD, Inc.) thereof, whether as a Holder of such Securities or as an underwriter, a placement or sales agent or a broker or dealer in respect thereof, or otherwise, assist such Broker-Dealer in complying with the requirements of such Rules and By-Laws, including, without limitation, by:

(i) if such Rules or By-Laws shall so require, engaging a “qualified independent underwriter” (as defined in such Rules) to participate in the preparation of the Registration Statement, to exercise usual standards of due diligence with respect thereto and, if any portion of the offering contemplated by such Registration Statement is an underwritten offering or is made through a placement or sales agent, to recommend the yield of such Securities;

(ii) indemnifying any such qualified independent underwriter to the extent of the indemnification of underwriters provided in Section 7 hereof; and

(iii) providing such information to such Broker-Dealer as may be required in order for such Broker-Dealer to comply with the requirements of such Rules.

(w) Prior to any public offering of the Securities or New Securities, pursuant to any Registration Statement, the Company shall register or qualify or cooperate with the Holders of the Securities included therein and their respective counsel in connection with the registration or qualification of the Securities for offer and sale under the securities or “blue sky” laws of such states of the United States as any Holder of the Securities reasonably requests in writing and do any and all other acts or things necessary or advisable to enable the offer and sale in such jurisdictions of the Securities covered by such Registration Statement; provided, however, that the Company shall not be required to (i) qualify generally to do business in any jurisdiction where it is not then so qualified or (ii) take any action which would subject it to general service of process or to taxation in any jurisdiction where it is not then so subject.

(x) The Company shall use its reasonable best efforts to take all other steps necessary to effect the registration of the Securities or the New Securities, as the case may be, covered by a Registration Statement.

5. Registration Expenses. The Company shall bear all expenses incurred in connection with the performance of its obligations under Sections 2, 3 and 4 hereof and, in the event of any Shelf Registration Statement, will reimburse the Holders for the reasonable fees and disbursements of one firm or counsel designated by the Majority Holders to act as counsel for the Holders in connection therewith, and, in the case of any Exchange Offer Registration Statement, will reimburse the Purchasers for the reasonable fees and disbursements of one firm or counsel acting in connection therewith. Notwithstanding the foregoing, the Holders shall pay all agency fees and commissions and underwriting discounts and commissions and the fees and disbursements of any counsel or other advisors or experts retained by such Holders (severally or jointly), other than the counsel specifically referred to above.

6. Additional Interest Under Certain Circumstances. The Company, the Purchasers and each Holder of Transfer Restricted Securities agree by acquisition of such Securities that the Holders of Transfer Restricted Securities will suffer damages if a Registration Default (as defined below) occurs and that it would not be feasible to ascertain the extent of such damages with precision. Accordingly, the Company, the Purchasers and each Holder of Transfer Restricted Securities agree that the following additional interest provisions shall constitute liquidated damages in the event of a “Registration Default” (as defined below) and shall constitute the sole remedy of the Purchasers and each Holder of Transfer Restricted Securities for any Registration Defaults.

(a) In accordance with the terms of the Securities, additional interest (“Additional Interest”) with respect to the Securities and New Securities shall be assessed as follows if any of the following events occur (each such event in clauses (i) through (iv) below being herein called a “Registration Default”):

(i) on or prior to the 90^th day following the Issue Date neither the Exchange Offer Registration Statement nor the Shelf Registration Statement has been filed with the Commission;

(ii) on or prior to the 180^th day following the Issue Date ( the “Effectiveness Target Date”), neither the Exchange Offer Registration Statement nor the Shelf Registration Statement has been declared effective;

(iii) on or prior to 30 Business Days following the Effectiveness Target Date, the Registered Exchange Offer has not been consummated; or

(iv) any Registration Statement required by this Agreement has been declared effective by the Commission but (A) such Registration Statement thereafter ceases to be effective or (B) such Registration Statement or the related prospectus ceases to be usable in connection with resales of Transfer Restricted Securities during the periods specified herein.

Each of the foregoing shall constitute a Registration Default whatever the reason for any such event and whether it is voluntary or involuntary or is beyond the control of the Company or pursuant to operation of law or as a result of any action or inaction by the Commission; provided, however, that the Company shall in no event be required to pay Additional Interest for more than one Registration Default at any given time.

Additional Interest shall be assessed on the Securities or New Securities, from and including the date on which any such Registration Default shall occur to but excluding the date on which all such Registration Defaults shall have been cured, at a rate of $.05 per week per $1,000 of principal amount of notes held (the “Additional Interest Amount”) for the first 90-day period immediately following the occurrence of such Registration Default. The Additional Interest Amount will increase by an additional $.05 per week per $1,000 of principal amount of notes with respect to each subsequent 90-day period until all Registration Defaults have been cured, up to a maximum amount of Additional Interest for all Registration Defaults of $.25 per week per $1,000 of principal amount of notes.

(b) Any amounts of Additional Interest due pursuant to Section 6(a) shall be paid to the Holders entitled thereto on June 1 and December 1 of any given year as more fully set forth in the Indenture and the Notes.

7. Indemnification and Contribution. (a) The Company agrees to indemnify and hold harmless each Holder of Securities or New Securities, as the case may be, covered by any Registration Statement (including each Purchaser and, with respect to any Prospectus delivery as contemplated in Section 4(h) hereof, each Exchanging Dealer), the directors, officers, employees and agents of each such Holder, Purchaser or Exchanging Dealer and each Person who controls any such Holder, Purchaser or Exchanging Dealer within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims,

damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement as originally filed or in any amendment thereof, or in any preliminary Prospectus or the Prospectus, or in any amendment thereof 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, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of the party claiming indemnification specifically for inclusion therein and provided, further, that the Company shall not be liable for any loss, claim, damage or expense (1) arising from any offer or sale of Securities or New Securities, as the case may be, covered by any Registration Statement, during a 30-day or 90 day period referenced in Section 5(k) hereof, of which the Holder has received written notice, or (2) if the Holder fails to deliver, within the time required by the Securities Act, a Prospectus that is amended or supplemented, and such Prospectus, as amended or supplemented, would have corrected the untrue statement or omission or alleged untrue statement or omission of a material fact contained in the Prospectus delivered by the Holder, so long as the Prospectus, as amended or supplemented, has been delivered to such Holder prior to such time. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

The Company also agrees to indemnify or contribute as provided in Section 7(d) to Losses of any underwriter of Securities or New Securities, as the case may be, registered under a Shelf Registration Statement, their directors, officers, employees or agents and each Person who controls such underwriter on substantially the same basis as that of the indemnification of the Purchasers and the selling Holders provided in this Section 7(a) and shall, if requested by any Holder, enter into an underwriting agreement reflecting such agreement, as provided in Section 4(p) hereof.

(b) Each Holder of securities covered by a Registration Statement (including each Purchaser and, with respect to any Prospectus delivery as contemplated in Section 4(h) hereof, each Exchanging Dealer) severally, but not jointly, agrees to indemnify and hold harmless the Company, each of its directors, each of its officers who signs such Registration Statement and each Person who controls the Company within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company to each such Holder, but only with reference to written information relating to such Holder furnished to the Company by or on behalf of such Holder specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any such Holder may otherwise have.

(c) Promptly after receipt by an indemnified party under this Section 7 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section, notify the indemnifying

party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and is prejudiced thereby; and (ii) 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) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest; (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party; (iii) 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 the institution of such action; or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes (i) an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and (ii) does not include a statement as to or an admission of fault or failure to act by or on behalf of any indemnified party. No indemnifying party shall be liable under subsections (a), (b) or (c) of this Section for any settlement of any claim or action effected without its consent, which consent will not be unreasonably withheld; provided, however, that such indemnifying party has notified in writing the indemnified party of its refusal to accept such settlement within 30 days of its receipt of a notice from the indemnified party outlining the terms of such settlement.

(d) In the event that the indemnity provided in paragraph (a) or (b) of this Section is unavailable to or insufficient to hold harmless an indemnified party for any reason, then each applicable indemnifying party shall have a joint and several obligation to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively “Losses”) to which such indemnified party may be subject in such proportion as is appropriate to reflect the relative benefits received by such indemnifying party, on the one hand, and such indemnified party, on the other hand, from the Initial Placement and the Registration Statement which resulted in such Losses; provided, however, that in no case shall any Purchaser of any Security or New Security be responsible, in the aggregate, for any amount in excess of the purchase discount

or commission applicable to such Security, or in the case of a New Security, applicable to the Security that was exchangeable into such New Security, as set forth in the Final Memorandum, nor shall any underwriter be responsible for any amount in excess of the underwriting discount or commission applicable to the securities purchased by such underwriter under the Registration Statement which resulted in such Losses, nor shall any subsequent Holder of any Security or New Security be responsible, in the aggregate, for any amount in excess of the net proceeds received by such Holder from the resale of such securities under the Registration Statement which resulted in such Losses. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the indemnifying party and the indemnified party shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of such indemnifying party, on the one hand, and such indemnified party, on the other hand, in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Relative fault shall be determined by reference to, among other things, whether any alleged untrue statement or omission relates to information provided by the indemnifying party, on the one hand, or by the indemnified party, on the other hand, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The parties agree that it would not be just and equitable if contribution were determined by pro rata allocation (even if the Holders were treated as one entity for such purpose) or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. For purposes of this Section, each Person who controls a Holder within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of such Holder shall have the same rights to contribution as such Holder, and each Person who controls the Company within the meaning of either the Act or the Exchange Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d).

(e) The provisions of this Section will remain in full force and effect, regardless of any investigation made by or on behalf of any Holder or the Company or any of the officers, directors or controlling Persons referred to in this Section hereof, and will survive the sale by a Holder of securities covered by a Registration Statement.

8. Underwritten Registrations. In connection with any Shelf Registration Statement required under this Agreement, the Company may enter into one or more underwriting agreements, engagement letters, agency agreements, “best efforts” underwriting agreements or similar agreements, as appropriate, including customary provisions relating to indemnification and contribution, and take such other actions in connection therewith as the Majority Holders shall request in order to expedite or facilitate the disposition of such Securities.

(a) If any of the Securities or New Securities, as the case may be, covered by any Shelf Registration Statement are to be sold in an underwritten offering, the Managing Underwriters shall be selected by the Majority Holders provided that such Managing Underwriters shall be reasonably satisfactory to the Company.

(b) No Person may participate in any underwritten offering pursuant to any Shelf Registration Statement, unless such Person (i) agrees to sell such Person’s Securities or New Securities, as the case may be, on the basis reasonably provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements; and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements.

9. No Inconsistent Agreements. The Company has not, as of the date hereof, entered into, nor shall it, on or after the date hereof, enter into, any agreement with respect to its securities that is inconsistent with the rights granted to the Holders herein or otherwise conflicts with the provisions hereof.

10. Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be amended, qualified, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, unless the Company has obtained the written consent of the Majority Holders (or, after the consummation of any Registered Exchange Offer in accordance with Section 2 hereof, of New Securities); provided that, with respect to any matter that directly or indirectly affects the rights of any Purchaser hereunder, the Company shall obtain the written consent of each such Purchaser against which such amendment, qualification, supplement, waiver or consent is to be effective. Notwithstanding the foregoing (except the foregoing proviso), a waiver or consent to departure from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders whose Securities or New Securities, as the case may be, are being sold pursuant to a Registration Statement and that does not directly or indirectly affect the rights of other Holders may be given by the Majority Holders, determined on the basis of Securities or New Securities, as the case may be, being sold rather than registered under such Registration Statement.

11. Notices. All notices and other communications provided for or permitted hereunder shall be made in writing by hand-delivery, first-class mail, telex, telecopier or air courier guaranteeing overnight delivery:

(a) if to a Holder, at the most current address given by such holder to the Company in accordance with the provisions of this Section, which address initially is, with respect to each Holder, the address of such Holder maintained by the Registrar under the Indenture, with copies in like manner to the Representative.

(b) if to the Representative (for itself or on behalf of any or all of the Purchasers), initially at the address set forth in the Purchase Agreement; and

(c) if to the Company, initially at the address set forth in the Purchase Agreement with a copy to Company counsel at the following address:

The Company hereby agrees to extend the benefits of this Agreement to any Holder of Securities and the New Securities, and any such Holder may specifically enforce the provisions of this Agreement as if an original party hereto.

17. Securities Held by the Company, Etc. Whenever the consent or approval of Holders of a specified percentage of the principal amount of Securities or New Securities is required hereunder, Securities or New Securities, as applicable, held by the Company or its Affiliates (other than subsequent Holders of Securities or New Securities if such subsequent Holders are deemed to be Affiliates solely by reason of their holdings of such Securities or New Securities) shall not be counted in determining whether such consent or approval was given by the Holders of such required percentage.

If the foregoing is in accordance with your understanding of our agreement, please sign and return to us the enclosed duplicate hereof, whereupon this letter and your acceptance shall represent a binding agreement among the Company and the several Purchasers.

Each Broker-Dealer that receives New Securities for its own account pursuant to the Exchange Offer must acknowledge that it will deliver a prospectus in connection with any resale of such New Securities. The Letter of Transmittal states that by so acknowledging and by delivering a prospectus, a Broker-Dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Act. This Prospectus, as it may be amended or supplemented from time to time, may be used by a Broker-Dealer in connection with resales of New Securities received in exchange for Securities where such Securities were acquired by such Broker-Dealer as a result of market-making activities or other trading activities. The Company has agreed that, starting on the Expiration Date (as defined herein) and ending on the close of business 180 days after the Expiration Date, it will make this Prospectus available to any Broker-Dealer for use in connection with any such resale. See “Plan of Distribution”.

PLAN OF DISTRIBUTION

Each Broker-Dealer that receives New Securities for its own account pursuant to the Exchange Offer must acknowledge that it will deliver a prospectus in connection with any resale of such New Securities. This Prospectus, as it may be amended or supplemented from time to time, may be used by a Broker-Dealer in connection with resales of New Securities received in exchange for Securities where such Securities were acquired as a result of market-making activities or other trading activities.

Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such Broker-Dealer and/or the purchasers of any such New Securities. Any Broker-Dealer that resells New Securities that were received by it for its own account pursuant to the Exchange Offer and any broker or dealer that participates in a distribution of such New Securities may be deemed to be an “underwriter” within the meaning of the Act and any profit of any such resale of New Securities and any commissions or concessions received by any such Persons may be deemed to be underwriting compensation under the Act.

Securityholder Questionnaire

(Date)

Pursuant to the American Tower Corporation Registration Rights Agreement, the Company has filed with the United States Securities and Exchange Commission (the “Commission”) a registration statement on Form (the “Shelf Registration Statement”) for the registration and resale under Rule 415 of the Securities Act of 1933, as amended (the “Securities Act”), of the Company’s 7.50% Senior Notes due 2012 (the “Securities”).
