        The Company expressly reserves the right, in its sole discretion but subject to applicable law, to (i) waive any and all of the conditions of an Offer, other than those dependent upon the receipt of necessary government approvals, prior to the applicable Expiration Time, (ii) extend the Expiration Time of an Offer, (iii) amend the terms of an Offer or (iv) if the conditions to an Offer are not satisfied, terminate such Offer and not accept for payment any Debentures tendered in such Offer. Any extension, amendment or termination will be followed as promptly as practicable by a public announcement thereof, such announcement in the case of an extension to be issued no later than 9:00 a.m., New York City time, on the next business day after the last previously scheduled or announced Expiration Time. The foregoing rights are in addition to the Company's right to delay the acceptance for payment of Debentures tendered pursuant to each Offer, or the payment for Debentures accepted for payment, in order to permit any or all conditions to such Offer to be satisfied or waived or to comply in whole or in part with any applicable law, subject, in each case, however, to Rules 13e-4 and 14e-1 under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), which require that an offeror pay the consideration offered or return the securities deposited by or on behalf of the holders thereof promptly after the termination or withdrawal of a tender offer.

        In the event that an Offer is terminated, withdrawn or otherwise lawfully not consummated, the applicable Consideration will not be paid or become payable to Holders who have validly tendered their Debentures pursuant to such Offer. In any such event, the Debentures previously tendered pursuant to that Offer will be promptly returned to the tendering Holders.

THE COMPANY AND THE PARTNERSHIP DISCLAIM ANY OBLIGATION TO

UPDATE OR REVISE ANY OF THE INFORMATION CONTAINED OR INCORPORATED BY REFERENCE HEREIN TO THE EXTENT NOT OTHERWISE REQUIRED BY APPLICABLE LAW.

        THIS OFFER TO PURCHASE DOES NOT CONSTITUTE AN OFFER TO PURCHASE IN ANY JURISDICTION, DOMESTIC OR FOREIGN, IN WHICH, OR TO OR FROM ANY PERSON TO OR FROM WHOM, IT IS UNLAWFUL TO MAKE SUCH OFFER UNDER APPLICABLE SECURITIES OR "BLUE SKY" LAWS.

        THIS OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN IMPORTANT INFORMATION WHICH SHOULD BE READ BEFORE ANY DECISION IS MADE WITH RESPECT TO THE OFFERS.

        A beneficial owner of the Debentures that are held of record by a broker, dealer, commercial bank, trust company or other nominee must instruct such broker, dealer, commercial bank, trust company or other nominee to tender the Debentures on the beneficial owner's behalf. DTC has authorized DTC Participants (as defined below) that hold Debentures on behalf of beneficial owners of Debentures through DTC to tender their Debentures as if they were Holders. The Depositary and DTC have confirmed that each Offer is eligible for DTC's Automated Tender Offer Program ("ATOP"). Accordingly, to effect such a tender of Debentures held in DTC, DTC Participants must tender their Debentures through ATOP and follow the procedures set forth in "Procedures for Tendering and Withdrawing Debentures—Debentures Held Through DTC". Holders desiring to tender their Debentures on the day when the applicable Expiration Time occurs should be aware that they must allow sufficient time for completion of the ATOP procedures during normal business hours of DTC on such day.

        Any Holder who desires to tender Debentures and who holds physical certificates evidencing such Debentures must complete and sign a Letter of Transmittal (or a manually signed facsimile thereof) in accordance with the instructions therein, have the signature thereon guaranteed (if required by Instruction 2 of the Letter of Transmittal) and deliver such manually signed Letter of Transmittal (or a manually signed facsimile thereof), together with certificates evidencing such Debentures being tendered and any other required documents to the Depositary, at its address set forth on the back cover of this Offer to Purchase prior to the applicable Expiration Time. As of the date hereof, all Debentures are held through DTC and therefore the procedures described in the immediately preceding paragraph will apply unless physical certificates evidencing Debentures were issued following the date hereof.

        Tendering Holders will not be obligated to pay brokerage fees or commissions or the fees and expenses of the Dealer Manager, the Information Agent or the Depositary. See "Dealer Manager; Information Agent; Depositary".

        There are no guaranteed delivery provisions provided for by the Company in connection with the Offers under the terms of this Offer to Purchase or any other related documents.

THE OFFERS

Introduction

        The Company hereby offers, upon the terms and subject to the conditions set forth in this Offer to Purchase and the Letter of Transmittal, to purchase for cash any and all of the Debentures that are validly tendered and not validly withdrawn prior to the applicable Expiration Time for the applicable Consideration set forth above under "Summary—Consideration; Accrued Interest" per $1,000 principal amount of the Debentures so purchased, plus Accrued Interest on such Debentures, if any.

        The Debentures are fully and unconditionally guaranteed by the Partnership as to all payments due on the Debentures whether at their stated maturity date, by acceleration, redemption, repayment or otherwise in accordance with the terms of such guarantee and the indenture. The guarantee is not separable from the Debentures and no separate consideration was paid to the Partnership by the initial purchasers of the Debentures for such guarantee. Accordingly, any Debentures validly tendered and not validly withdrawn and accepted for purchase by the Company will result in the tendering of the related guarantee and its cancellation for no additional consideration and all references to the Debentures are deemed to include references to the guarantees.

        Upon the terms and subject to the satisfaction or waiver of all conditions, other than, in the case of any waiver, those dependent upon the receipt of necessary government approvals, set forth herein and in the Letter of Transmittal, the Company will, promptly after the applicable Expiration Time, accept for payment any and all Debentures validly tendered and not validly withdrawn prior to such Expiration Time. If a Holder validly tenders its Debentures prior to the applicable Expiration Time and does not validly withdraw its Debentures prior to the applicable Expiration Time and the Company accepts such Debentures for payment, upon the terms and subject to the conditions of the applicable Offer, the Company will pay the applicable Consideration plus Accrued Interest for such Debentures on the Payment Date.

        Debentures accepted for payment pursuant to an Offer will be accepted only in principal amounts of $1,000 or an integral multiple thereof.

Consideration; Accrued Interest

        The Consideration for the applicable series of Debentures accepted for payment will be paid on the Payment Date, which will be promptly after the Expiration Time. It is expected that the Payment Date will be one business day after the applicable Expiration Time. Such payments will be made by the deposit of immediately available funds by the Company with the Depositary or, upon its instructions, DTC. The Depositary and/or DTC will act as agents for the tendering Holders for the purpose of receiving payments from the Company and transmitting such payments to such Holders. See "Acceptance for Payment and Payment".

        Tenders of Debentures pursuant to an Offer may be validly withdrawn at any time prior to the applicable Expiration Time by following the procedures described herein. In addition, if not previously accepted for payment, tendered Debentures may be withdrawn after the date that is 40 business days after the commencement of the Offers. If Holders validly withdraw previously tendered Debentures, such Holders will not receive the applicable Consideration, unless such Debentures are validly retendered and not again validly withdrawn prior to the applicable Expiration Time (and the Company accepts the Debentures for payment, upon the terms and subject to the conditions of the Offers).

        Holders whose Debentures are accepted for payment pursuant to an Offer will be entitled to receive Accrued Interest on those Debentures. Under no circumstances will any additional interest be payable because of any delay in the transmission of funds to the Holders of purchased Debentures.

Without limiting the manner in which the Company may choose to make such announcement, the Company shall not, unless required by law, have any obligation to publish, advertise or otherwise communicate any such announcement other than by issuing a press release.

        If the Company extends an Offer or delays its acceptance for payment, or its payment, for any Debentures tendered in such Offer for any reason, then, without prejudice to the Company's rights under that Offer, the Depositary may retain tendered Debentures on behalf of the Company. However, the ability of the Company to delay acceptance for payment, or payment, for Debentures that are validly tendered and not withdrawn prior to the applicable Expiration Time is limited by Rules 13e-4 and 14e-1(c) under the Exchange Act, which require that an offeror pay the consideration offered or return the securities deposited by or on behalf of Holders promptly after the termination or withdrawal of a tender offer.

        If the Company makes a material change in the terms and conditions of an Offer or the information concerning such Offer, the Company will disseminate additional offering materials and extend that Offer to the extent required by law, including Rule 13e-4 under the Exchange Act.

Purpose of the Transaction

        The purpose of the Offers is to repurchase Debentures in order to reduce the amount of the Company's outstanding indebtedness and the associated interest expense. Any Debentures we purchase in the Offers will be cancelled.

Source and Amount of Funds

        We expect that we will need approximately $412.5 million to purchase the Debentures pursuant to the Offers (not including Accrued Interest and expenses related to the Offers), assuming all outstanding Debentures are validly tendered and accepted for payment. The Company intends to fund its purchases of Debentures in the Offers from its available cash paid to the Company by the Partnership in satisfaction of the Partnership's obligations to us.

PROCEDURES FOR TENDERING AND WITHDRAWING DEBENTURES

        The tender of Debentures pursuant to the Offers and in accordance with the procedures described below will constitute a valid tender of Debentures. If a Holder validly tenders its Debentures prior to the applicable Expiration Time and does not validly withdraw its Debentures prior to the applicable Expiration Time and the Company accepts such Debentures for payment, upon the terms and subject to the conditions of the Offers, the Company will pay such Holder the applicable Consideration plus Accrued Interest for such Debentures on the Payment Date. Any Debentures tendered and validly withdrawn prior to the applicable Expiration Time will be deemed not to have been validly tendered.

Tendering Debentures

        The tender of Debentures pursuant to any of the procedures described in this Offer to Purchase and set forth in the Letter of Transmittal will constitute a binding agreement between the tendering Holder and the Company upon the terms and subject to the conditions of the Offers. Such agreement will be governed by, and construed in accordance with, the laws of the State of New York. The valid tender of Debentures will constitute the agreement of the Holder to deliver good and marketable title to all tendered Debentures, free and clear of all liens, charges, claims, encumbrances, interests and restrictions of any kind.

        UNLESS THE DEBENTURES BEING TENDERED ARE DEPOSITED BY THE HOLDER WITH THE DEPOSITARY PRIOR TO THE APPLICABLE EXPIRATION TIME (ACCOMPANIED, TO THE EXTENT NECESSARY, BY A PROPERLY COMPLETED AND DULY EXECUTED LETTER OF TRANSMITTAL), THE COMPANY MAY, AT ITS OPTION, REJECT SUCH TENDER. PAYMENT FOR DEBENTURES WILL BE MADE ONLY AGAINST DEPOSIT OF VALIDLY TENDERED DEBENTURES AND DELIVERY OF ANY REQUIRED DOCUMENTS.

        Only registered Holders of Debentures are authorized to tender certificated Debentures pursuant to the Offers.

        To properly tender Debentures or cause Debentures to be tendered, the following procedures must be followed:

Debentures Held Through DTC

        With regard to Debentures held in book-entry form through DTC, DTC or its nominee is the sole registered owner—and thus the sole Holder—of those Debentures. Beneficial owners of Debentures held through a participant (a "DTC Participant") of DTC (i.e., a custodian bank, depositary, broker, dealer, trust company or other nominee) are not Holders of the Debentures, and any such beneficial owner that wishes its Debentures to be tendered in an Offer must instruct the DTC Participant through which its Debentures are held to cause its Debentures to be tendered and delivered to the Depositary in accordance with DTC's ATOP procedures as described in this Offer to Purchase. Beneficial owners and DTC Participants desiring that Debentures be tendered on the day on which the applicable Expiration Time is to occur should be aware that they must allow sufficient time for completion of the ATOP procedures during normal business hours of DTC on such day.

        Clearstream, Luxembourg and Euroclear are DTC Participants. Beneficial owners who hold the Debentures through Euroclear and Clearstream, Luxembourg must follow DTC's procedures for tender and delivery of the Debentures. Euroclear and Clearstream, Luxembourg may not be open for business on days when banks, brokers and other institutions are open for business in the United States. For this reason, and because of time-zone differences, investors who hold interests in the Debentures through these systems and wish to have the Debentures tendered may find that the transaction will not be effected when requested and perhaps not until the next business day in Luxembourg or Brussels, as applicable. Thus, those who hold interests through Clearstream, Luxembourg or Euroclear and wish to have Debentures tendered prior to the applicable Expiration Time must take into consideration differences in business days and time-zones so as to allow sufficient time to have the tenders effected.

Table of Contents

        The Depositary and DTC have confirmed that the Offers are eligible for ATOP. Pursuant to an authorization given by DTC to DTC Participants, each DTC Participant that holds Debentures through DTC and chooses to accept an Offer must transmit its acceptance through ATOP, and DTC will then edit and verify the acceptance, execute a book-entry delivery to the Depositary's account at DTC and send an Agent's Message (as defined below) to the Depositary for its acceptance. The Depositary will (promptly after the date of this Offer to Purchase) establish accounts at DTC for purposes of the Offers with respect to Debentures held through DTC, and any financial institution that is a DTC Participant may make book-entry delivery of Debentures into the Depositary's account through ATOP. However, although delivery of the Debentures may be effected through book-entry transfer into the Depositary's account through ATOP, an Agent's Message in connection with such book-entry transfer and any other required documents must be, in any case, transmitted to and received by the Depositary at its address set forth on the back cover of this Offer to Purchase prior to the applicable Expiration Time. Delivery of documents to DTC. the Company, the Partnership or the Dealer Manager does not constitute delivery to the Depositary. The confirmation of a book-entry transfer into the Depositary's account at DTC as described above is referred to herein as a "Book-Entry Confirmation".

        The term "Agent's Message" means a message transmitted by DTC to, and received by, the Depositary and forming a part of the Book-Entry Confirmation, which states that DTC has received an express acknowledgment from each DTC Participant tendering through ATOP that such DTC Participant has received a Letter of Transmittal and agrees to be bound by the terms of the Letter of Transmittal and that the Company may enforce such agreement against such DTC Participant.

        All Debentures currently held through DTC have been issued in the form of global notes registered in the name of Cede & Co., DTC's nominee (the "Global Debentures"). At or as of the close of business on the second business day after the applicable Expiration Time, the aggregate principal amount of the Global Debentures will be reduced to represent the aggregate principal amount of the Debentures, if any, held through DTC and not tendered pursuant to the Offers.

Debentures Held by Record Holders

        As of the date hereof, all Debentures are held in book-entry form through DTC and unless physical certificates are issued following the date hereof, the tendering procedures for book-entry holdings described above should be followed except for Debentures registered in the name of DTC or its nominees. However, in the event that after the date hereof physical certificates evidencing the Debentures are issued to a Holder other than DTC or its nominee, then any such Holder of the Debentures must complete and sign the Letter of Transmittal, and deliver such Letter of Transmittal and any other documents required by the Letter of Transmittal, together with certificate(s) representing all such tendered Debentures, to the Depositary at its address set forth on the back cover of this Offer to Purchase prior to the applicable Expiration Time.

        BENEFICIAL OWNERS OF DEBENTURES—I.E., THOSE WHO HOLD INTERESTS IN THE DEBENTURES THROUGH A CUSTODIAN BANK, DEPOSITARY, BROKER, DEALER, TRUST COMPANY OR OTHER NOMINEE OR THROUGH DTC—ARE NOT HOLDERS OF THEIR DEBENTURES; ONLY THE NOMINEES OF THOSE PERSONS (OR DTC) IN WHOSE NAME THE DEBENTURES ARE REGISTERED ON THE COMPANY'S REGISTER OF DEBENTURES ARE THE HOLDERS OF THE DEBENTURES AND MAY TENDER THE DEBENTURES IN THE OFFERS.

        All signatures on the Letter of Transmittal must be guaranteed by a recognized participant in the Securities Transfer Agents Medallion Program, the NYSE Medallion Signature Program or the Stock Exchange Medallion Program (each, an "Eligible Institution"); provided, however, that signatures on the Letter of Transmittal need not be guaranteed if such Debentures are tendered for the account of an Eligible Institution. See Instruction 2 of the Letter of Transmittal. If a Letter of Transmittal or any Debenture is signed by a trustee, executor, administrator, guardian, attorney-in-fact, agent, officer of a corporation or other person acting in a fiduciary or representative capacity, such person must so

indicate when signing, and proper evidence satisfactory to the Company of the authority of such person so to act must be submitted.

Lost or Missing Certificates

        If a Holder desires to tender Debentures pursuant to the Offers, but the certificates representing such Debentures have been mutilated, lost, stolen or destroyed, such Holder should contact the Depositary for further instructions at the address or telephone number set forth on the back cover of this Offer to Purchase. See Instruction 10 of the Letter of Transmittal.

Backup U.S. Federal Income Tax Withholding

        Under the "backup withholding" provisions of U.S. federal income tax law, unless a beneficial owner, or such beneficial owner's assignee, satisfies the conditions described in Instruction 8 of the Letter of Transmittal or is otherwise exempt, the aggregate applicable Consideration and Accrued Interest may be subject to backup withholding at a rate of 28%. To prevent backup withholding, each U.S. Holder (as defined below in "Material U.S. Federal Income Tax Consequences") should complete and sign the Substitute Form W-9 provided in the Letter of Transmittal. Each Non-U.S. Holder (as defined below in "Material U.S. Federal Income Tax Consequences") must submit the appropriate completed Internal Revenue Service ("IRS") Form W-8 (generally Form W-8BEN for a Non-U.S. Holder) to avoid backup withholding. See Instruction 8 of the Letter of Transmittal.

Effect of Letter of Transmittal

        Subject to, and effective upon, the acceptance for payment of, and payment for, the Debentures tendered thereby, by executing and delivering a Letter of Transmittal a tendering Holder of Debentures (i) irrevocably sells, assigns and transfers to, or upon the order of, the Company, all right, title and interest in and to all the Debentures tendered thereby, (ii) waives any and all rights with respect to such Debentures (including, without limitation, any existing or past defaults and their consequences in respect of such Debentures and the indenture under which the Debentures were issued), (iii) releases and discharges the Company and the Partnership from any and all claims such Holder may have now, or may have in the future arising out of, or related to, such Debentures, including, without limitation, the Partnership's guarantee of the Debentures, any claims that such Holder is entitled to receive additional principal or interest payments with respect to such Debentures, to convert the Debentures into cash or or a combination of cash and the Company's common shares of beneficial interest, per value $0.04 per share ("Common Shares"), to participate in any redemption of such Debentures or be entitled to any of the benefits under the indenture under which the Debentures were issued; and (iv) irrevocably constitutes and appoints the Depositary as the true and lawful agent and attorney-in-fact of such Holder with respect to any such tendered Debentures (with full knowledge that the Depositary also acts as the agent of the Company) with respect to such Debentures, with full power of substitution and resubstitution (such power of attorney being deemed to be an irrevocable power coupled with an interest) to (a) deliver certificates representing such Debentures, or transfer ownership of such Debentures on the account books maintained by DTC, together, in any such case, with all accompanying evidences of transfer and authenticity, to the Company, (b) present such Debentures for transfer on the relevant security register, (c) receive all benefits or otherwise exercise all rights of beneficial ownership of such Debentures (except that the Depositary will have no rights to, or control over, funds from the Company, except as agent for the tendering Holders, for the applicable Consideration and Accrued Interest for any tendered Debentures that are purchased by the Company) and (d) deliver to the Company the Letter of Transmittal, all upon the terms and subject to the conditions of the Offers.

Determination of Validity

        All questions as to the validity, form, eligibility (including time of receipt) and acceptance for payment of Debentures pursuant to the procedures described in this Offer to Purchase and the Letter of Transmittal and the form and validity of all documents will be determined by the Company in its sole discretion. The Company reserves the absolute right to reject any or all tenders that are not in proper form or the acceptance of or payment for which may, upon the advice of counsel for the Company, be unlawful. The Company also reserves the absolute right to waive any of the conditions of the Offers, other than those dependent upon the receipt of necessary government approvals, and any defect or irregularity in the tender of any particular Debentures. Any determination by the Company as to the validity, form, eligibility and acceptance of Debentures for payment, or any interpretation by the Company as to the terms and conditions of the Offers, is subject to applicable law and, if challenged by Holders or otherwise, to the judgment of a court of competent jurisdiction. The Company is not obligated and does not intend to accept any alternative, conditional or contingent tenders. Unless waived, any irregularities in connection with tenders must be cured within such time as the Company shall determine. None of the Company, the Partnership or any of their affiliates or assigns, the Depositary, the Information Agent, the Dealer Manager or any other person will be under any duty to give notification of any defects or irregularities in such tenders or will incur any liability to a Holder for failure to give such notification. Tenders of Debentures will not be deemed to have been made until such irregularities have been cured or waived. Any Debentures received by the Depositary that are not properly tendered and as to which the irregularities have not been cured or waived will be returned by the Depositary to the tendering Holders, unless otherwise provided in the Letter of Transmittal, as promptly as practical following the Expiration Time.

        LETTERS OF TRANSMITTAL AND DEBENTURES MUST BE SENT ONLY TO THE DEPOSITARY. DO NOT SEND LETTERS OF TRANSMITTAL OR DEBENTURES TO THE COMPANY, THE PARTNERSHIP, THE DEALER MANAGER OR THE INFORMATION AGENT.

        THE METHOD OF DELIVERY OF DEBENTURES AND LETTERS OF TRANSMITTAL, ANY REQUIRED SIGNATURE GUARANTEES AND ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH DTC AND ANY ACCEPTANCE THROUGH ATOP, IS AT THE ELECTION AND RISK OF THE PERSONS TENDERING AND DELIVERING LETTERS OF TRANSMITTAL AND, EXCEPT AS OTHERWISE PROVIDED IN THE LETTER OF TRANSMITTAL, DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY. IF DELIVERY IS BY MAIL, IT IS SUGGESTED THAT THE HOLDER USE PROPERLY INSURED, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, AND THAT THE MAILING BE MADE SUFFICIENTLY IN ADVANCE OF THE EXPIRATION TIME TO PERMIT DELIVERY TO THE DEPOSITARY PRIOR TO THE APPLICABLE EXPIRATION TIME.

        IF YOU HOLD YOUR DEBENTURES THROUGH A CUSTODIAN BANK, DEPOSITARY, BROKER, DEALER, TRUST COMPANY OR OTHER NOMINEE, YOU SHOULD KEEP IN MIND THAT SUCH ENTITY MAY REQUIRE YOU TO TAKE ACTION WITH RESPECT TO THE OFFERS A NUMBER OF DAYS BEFORE THE APPLICABLE EXPIRATION TIME IN ORDER FOR SUCH ENTITY TO TENDER DEBENTURES ON YOUR BEHALF ON OR PRIOR TO SUCH EXPIRATION TIME. TENDERS NOT COMPLETED BY THE DEPOSITARY PRIOR TO THE EXPIRATION TIME WILL BE DISREGARDED AND OF NO EFFECT.

No Appraisal Rights

        No appraisal rights are available to holders of Debentures under applicable law in connection with the Offers.

No Guaranteed Delivery

        There are no guaranteed delivery provisions provided for by the Company in connection with the Offers under the terms of this Offer to Purchase or any other related documents. Holders must tender their Debentures in accordance with the procedures set forth above and complete such procedures prior to the applicable Expiration Time in order to be eligible to receive the applicable Consideration.

Withdrawal of Tenders by Holders

        Except as otherwise provided herein, tenders of Debentures pursuant to the Offers are irrevocable. Withdrawal of Debentures by Holders may only be accomplished in accordance with the following procedures.

        Holders may withdraw Debentures tendered in the Offers at any time prior to the applicable Expiration Time. Thereafter, such tenders may be withdrawn after the 40th business day following the commencement of an Offer, in accordance with Rule 13e-4(f) of the Exchange Act, unless such Debentures have been accepted for payment as provided in this Offer to Purchase. If the Company extends an Offer, is delayed in its acceptance for payment of Debentures or is unable to purchase Debentures validly tendered under such Offer for any reason, then, without prejudice to the Company's rights under that Offer, the Depositary may nevertheless, on the Company's behalf, retain tendered Debentures, and such Debentures may not be withdrawn except to the extent that the Holder is entitled to withdrawal rights described herein.

        For a withdrawal of a tender of Debentures to be effective, a written or facsimile transmission notice of withdrawal must be received by the Depositary prior to the applicable Expiration Time, by mail, or hand delivery or by a properly transmitted "Request Message" through ATOP.

        Any such notice of withdrawal must (i) specify the name of the person who tendered the Debentures to be withdrawn and the name in which those Debentures are registered (or, if tendered by a book-entry transfer, the name of the participant in DTC whose name appears on the security position listing as the owner of such Debentures), if different from that of the person who deposited the Debentures, (ii) contain the description of the Debentures to be withdrawn, the certificate number or numbers of such Debentures, unless such Debentures were tendered by book-entry delivery, and the aggregate principal amount represented by such Debentures, (iii) unless transmitted through ATOP, be signed by the Holder thereof in the same manner as the original signature on such Holder's Letter of Transmittal, including any required signature guarantee(s), or be accompanied by documents of transfer sufficient to have the applicable Debenture trustee register the transfer of the Debentures into the name of the person withdrawing such Debentures and (iv) if a Letter of Transmittal in relation to the Debentures to be withdrawn was executed by a person other than the registered Holder, be accompanied by a properly completed irrevocable proxy that authorized such person to effect such withdrawal on behalf of such Holder.

        The Company will determine, in its sole discretion, all questions as to the form and validity (including time of receipt) of any notice of withdrawal. Any such determination is subject to applicable law and, if challenged by Holders or otherwise, to the judgment of a court of competent jurisdiction. No withdrawal of Debentures shall be deemed to have been validly made until all defects and irregularities have been cured or waived. None of the Company, the Partnership or any of their affiliates or assigns, the Depositary, the Information Agent, the Dealer Manager or any other person will be under any duty to give notification of any defects or irregularities in any notice of withdrawal or incur any liability for failure to give such notification. Withdrawals of tenders of Debentures may not be rescinded, and any Debentures validly withdrawn will be deemed not to have been validly tendered for purposes of an Offer. However, Holders may retender withdrawn Debentures by following one of the procedures for tendering Debentures described herein at any time prior to the applicable Expiration Time.

The Payment Date will be promptly after the Expiration Time. The Payment Date is expected to be one business day after the applicable Expiration Time. Any Debentures so tendered and accepted for payment pursuant to an Offer will be cancelled.

        The Company, at its option, may elect to extend an Expiration Time with respect to an Offer to a later date and time announced by the Company, provided that public announcement of that extension will be made not later than 9:00 a.m., New York City time, on the next business day after the last previously scheduled or announced Expiration Time.

        The Company expressly reserves the right, in its sole discretion, to terminate the Offers and not accept for payment any Debentures tendered in the Offers if any of the conditions set forth under "Conditions to the Offers" shall not have been satisfied or waived by the Company or in order to comply in whole or in part with any applicable law. In addition, the Company expressly reserves the right, in its sole discretion, to delay acceptance for payment, or payment, for Debentures tendered in an Offer in order to permit any or all of those conditions to be satisfied or waived or to comply in whole or in part with any applicable law, subject in each case, however, to Rules 13e-4 and 14e-1(c) under the Exchange Act (which require that an offeror pay the consideration offered or return the securities deposited by or on behalf of the holders thereof promptly after the termination or withdrawal of a tender offer). In all cases, payment for Debentures accepted for payment pursuant to an Offer will be made only after timely receipt by the Depositary of certificates representing such Debentures (or confirmation of book-entry transfer of such Debentures), a properly completed and duly executed Letter of Transmittal (or a manually signed facsimile thereof or satisfaction of DTC's ATOP procedures) on or before the applicable Expiration Time, and any other documents required thereby.

        Upon the terms and subject to the conditions set forth herein and in the Letter of Transmittal, after the applicable Expiration Time, the Company will be deemed to have accepted for payment, and thereby purchased, all Debentures validly tendered and not validly withdrawn prior to such Expiration Time as, if and when the Company gives written notice to the Depositary of its acceptance for payment of such Debentures. On the Payment Date, the Company will deposit with the Depositary, or upon the Depositary's instructions, DTC, in respect of, and the Depositary or DTC, as the case may be, will thereafter transmit to the Holders of, Debentures accepted for payment, the applicable Consideration and Accrued Interest.

        If the Company extends an Offer or delays its acceptance for payment, or payment, for Debentures tendered in such Offer for any reason, then, without prejudice to the Company's rights under that Offer, the Depositary may retain tendered Debentures on behalf of the Company. However, the ability of the Company to delay such acceptance or payment is limited by Rules 13e-4 and 14e-1(c) under the Exchange Act as described above.

        The Company reserves the right to transfer or assign, in whole or from time to time in part, to one or more of its affiliates, the right to purchase all or any portion of the Debentures tendered pursuant to an Offer, but any such transfer or assignment will not relieve the Company of its obligations under such Offer and will in no way prejudice the rights of a tendering Holder to receive payment for its Debentures validly tendered and accepted for payment pursuant to that Offer.

        Holders whose Debentures are accepted for payment pursuant to an Offer will be entitled to any Accrued Interest on those Debentures. Under no circumstances will any additional interest be payable because of any delay in the transmission of funds to the Holders of purchased Debentures.

        Tendering Holders of Debentures will not be required to pay brokerage commissions or fees of the Dealer Manager, the Information Agent or the Depositary.

        If an Offer is terminated or the Debentures are validly withdrawn prior to the applicable Expiration Time, or the Debentures are not accepted for payment, the applicable Consideration will not be paid or become payable. If any tendered Debentures are not purchased pursuant to the Offers for any reason, or certificates are submitted evidencing more Debentures than are tendered, such Debentures not purchased will be returned, without expense, to the tendering Holder (or, in the case of Debentures tendered by book-entry transfer, such Debentures will be credited to the account maintained at DTC from which such Debentures were delivered), unless otherwise requested by such Holder as provided under "Special Issuance/Delivery Instructions" in the Letter of Transmittal, promptly following the applicable Expiration Time or termination of the Offers.

IMPACT OF THE OFFERS ON RIGHTS OF THE HOLDERS OF THE DEBENTURES

        The Company issued (i) $1.00 billion aggregate principal amount of its 2026 Debentures, which are fully and unconditionally guaranteed by the Partnership and (ii) $1.40 billion aggregate principal amount of its 2027 Debentures, which are fully and unconditionally guaranteed by the Partnership.

If the Company accepts Debentures for payment, upon the terms and subject to the conditions of the Offers, the Company will pay the Holders the applicable Consideration plus any Accrued Interest for all Debentures purchased from them in the Offers, and thereby such Holders will give up certain rights associated with their ownership of such Debentures.

        Holders of Debentures purchased in the Offers will forgo regular semi-annual payments of interest accruing on the principal of the Debentures at the rate of 3.625% per annum from and after the Payment Date, with respect to the 2026 Debentures, and 2.85% per annum from and after the Payment Date, with respect to the 2027 Debentures.

Conversion Rights of Holders

        Holders of 2026 Debentures purchased in the Offers will forgo the right to elect to convert those 2026 Debentures into cash, or a combination of cash and Common Shares, prior to the close of business on the second business day immediately preceding the maturity date for the 2026 Debentures (scheduled for November 15, 2026) at any time on and after November 15, 2025, and also under the following circumstances: (i) during any period from and including the 11th trading day in a fiscal quarter up to but excluding the 11th trading day of the following quarter, if at any time the closing sale price of the Common Shares is more than 125% of the conversion price per Common Share on the first day of such period for at least 20 trading days in the period of 30 consecutive trading days beginning on the first day of such period, (ii) during the five consecutive trading-day period following any 20 consecutive trading-day period in which the average of the trading prices for the 2026 Debentures was less than 98% of the average closing sale price of Common Shares multiplied by the applicable conversion rate, (iii) if the 2026 Debentures have been called for redemption, at any time prior to the close of business two business days prior to the redemption date, (iv) during prescribed periods upon the occurrence of specified corporate events or (v) if the Common Shares are not listed on a U.S. national securities exchange for 30 consecutive trading days. The initial conversion rate of the 2026 Debentures was 6.5168 Common Shares per $1,000 principal amount of 2026 Debentures (equivalent to an initial conversion price of approximately $153.45 per Common Share and currently

17

---

Table of Contents

approximately $148.46 per Common Share, which corresponds to a conversion rate of 6.7358 Common Shares per $1,000 principal amount of 2026 Debentures). The conversion rate for the 2026 Debentures is subject to adjustment in certain events, including in connection with certain mergers, asset sales or similar transactions involving the Company.

        Similarly, Holders of 2027 Debentures purchased in the Offers will forgo the right to elect to convert those 2027 Debentures into cash, or a combination of cash and Common Shares, prior to the close of business on the second business day immediately preceding the maturity date for the 2027 Debentures (scheduled for April 1, 2027) at any time on and after April 1, 2026, and also under the same circumstances described above with respect to the 2026 Debentures. The initial conversion rate of the 2027 Debentures was 6.1553 Common Shares per $1,000 principal amount of 2027 Debentures (equivalent to an initial conversion price of approximately $162.46 per Common Share and currently approximately $157.18 per Common Share, which corresponds to a conversion rate of 6.3621 Common Shares per $1,000 principal amount of 2027 Debentures). The conversion rate for the 2027 Debentures is subject to adjustment in certain events, including in connection with certain mergers, asset sales or similar transactions involving the Company.

Right of Holders to Receive Principal at Maturity

        Holders of Debentures purchased in the Offers will forgo the right to receive payment of the full principal amount of those Debentures on the maturity date for the Debentures. The 2026 Debentures and the 2027 Debentures are scheduled to mature on November 15, 2026 and April 1, 2027, respectively, but in each case the maturity is subject to acceleration upon certain events of default.

        Debentures purchased in the Offers will be cancelled and that cancellation will result in the extinguishment of the guarantee of the Debentures by the Partnership.

Right of Holders to Require Repurchase by the Company upon a Change of Control

        Holders of Debentures purchased in the Offers will forgo the right to require the Company to repurchase all or a portion of those Debentures upon the occurrence of certain changes in control of the Company at any time prior to November 15, 2011, in the case of the 2026 Debentures, and at any time prior to April 1, 2012, in the case of the 2027 Debentures, at a price equal to 100% of the principal amount of the Debentures to be purchased plus accrued and unpaid interest, to, but excluding, the purchase date, subject to certain exceptions.

ADDITIONAL CONSIDERATIONS CONCERNING THE OFFERS

        The following considerations, in addition to the other information described elsewhere herein or incorporated by reference herein, should be carefully considered by each Holder and owner of Debentures before deciding whether the Debentures should be tendered in the Offers. See "Where You Can Find Additional Information" and "Incorporation of Certain Documents by Reference".

Position of the Company Concerning the Offers

        Neither the Company, the Partnership, nor the Company's board of trustees nor the Dealer Manager, Depositary or Information Agent makes any recommendation to any Holder or owner of Debentures as to whether the Holder should tender or refrain from tendering any or all of such Holder's Debentures, and none of them has authorized any person to make any such recommendation. Holders and owners are urged to evaluate carefully all information in this Offer to Purchase, consult their own investment and tax advisors and make their own decisions whether to tender Debentures, and, if so, the principal amount of Debentures to tender.

Tax Treatment of Debentures Purchased in the Offers

        The receipt of the applicable Consideration in exchange for the Debentures will be a taxable transaction to U.S. Holders (as defined below). A U.S. Holder will recognize gain or loss in an amount equal to the difference between (i) the gross amount of the applicable Consideration, other than Accrued Interest, paid to the U.S. Holder in respect of its tendered Debentures and (ii) the U.S. Holder's adjusted tax basis in its tendered Debentures. Accrued Interest generally will be treated as ordinary income to the extent not previously included in income. Gain realized by a Non-U.S. Holder on the receipt of cash for Debentures generally will not be subject to U.S. federal income or withholding tax, except in certain circumstances as discussed in more detail below. Please see "Material U.S. Federal Income Tax Consequences" for a more detailed discussion.

Limited Trading Market for Debentures Not Purchased in the Offers

        The Debentures are not listed on any national or regional securities exchange or quoted on any automated quotation system. To our knowledge, the Debentures are traded infrequently in transactions arranged through brokers, and reliable market quotations for the Debentures are not available. To the extent that Debentures are tendered and accepted for payment pursuant to the Offers, the trading market for Debentures that remain outstanding is likely to be more limited. In addition, a debt security with a smaller outstanding principal amount available for trading (a smaller "float") may command a lower price than would a comparable debt security with a larger float. Thus, the market price for Debentures that are not tendered and accepted for payment pursuant to the Offers may be affected adversely to the extent that the Offers reduce the float for such Debentures. There is no assurance that an active market in the Debentures will exist or as to the prices at which the Debentures may trade after consummation of the Offers.

Substantial Existing Indebtedness

        The Company has substantial existing indebtedness. As of June 30, 2010, the Company had an aggregate of approximately $404,850,000 of total indebtedness, constituting senior debt of the Company on an unconsolidated basis. As of June 30, 2010, the Partnership had an aggregate of approximately $2,269,619,000 of total indebtedness, constituting senior debt of the Partnership on an unconsolidated basis, which amount includes $404,850,000 payable to the Company. While the Company will continue to have substantial indebtedness following the consummation of the Offers, the aggregate amount of its outstanding indebtedness with maturities in 2026 and 2027 will be reduced as a result of consummation of such Offer. The amount of the Company's indebtedness and restrictions contained in its other

19

---

Table of Contents

outstanding indebtedness may limit its ability to effect future financings in the event the Company should deem it necessary or desirable to raise additional capital. Further, there can be no assurance that the Company will have sufficient earnings, access to liquidity or cash flow in the future to meet its debt service obligations under the Debentures that remain outstanding following consummation of the Offers. For additional information about the Company's indebtedness, capitalization and financial condition, see its Annual Report on Form 10-K, as amended, for the fiscal year ended December 31, 2009, its Quarterly Reports on Form 10-Q for the quarterly periods ended March 31, 2010 and June 30, 2010 and the other information incorporated by reference herein. See "Incorporation of Documents by Reference."

Treatment of Debentures Not Purchased in the Offers

        Debentures not tendered and/or accepted for payment in the Offers will remain outstanding immediately following the completion of the Offers. The terms and conditions governing the Debentures, including the covenants and other protective provisions contained in the 2006 Indenture, which governs the Debentures, will remain unchanged immediately following the completion of the Offers. No amendment to the 2006 Indenture is being sought. From time to time after the tenth business day following the applicable Expiration Time or other date of termination of an Offer, we or our affiliates may acquire Debentures that remain outstanding through open market purchases, privately negotiated transactions, tender offers, exchange offers or otherwise, upon such terms and at such prices as they may determine, which may be more or less than the price to be paid pursuant to such Offer and could be for cash or other consideration. Alternatively, we may, subject to certain conditions, redeem any or all of the Debentures not purchased pursuant to the Offers at any time that we are permitted to do so under the terms of the Debentures. There can be no assurance as to which, if any, of these alternatives (or combinations thereof) we or our subsidiaries will choose to pursue in the future.

MARKET INFORMATION ABOUT THE DEBENTURES AND THE COMMON SHARES

        There is no established reporting system or trading market for trading in the Debentures. To the extent that the Debentures are traded, prices of the Debentures may fluctuate greatly depending on the trading volume and the balance between buy and sell orders. To our knowledge, the Debentures are traded infrequently in transactions arranged through brokers, and reliable market quotations for the Debentures are not available.

        The Company's Common Shares are listed on the New York Stock Exchange under the symbol "VNO". The following table sets forth, for the periods indicated, the high and low sales prices in U.S. dollars for our common shares as reported by the Consolidated Tape Association.

 

 

        On August 31, 2010, the last reported sale price of our Common Shares on the New York Stock Exchange was $81.06 per share. We had 182,601,039 Common Shares, outstanding as of August 31, 2010.

        HOLDERS ARE URGED TO OBTAIN CURRENT MARKET QUOTATIONS FOR OUR COMMON SHARES AND, TO THE EXTENT AVAILABLE, THE DEBENTURES, PRIOR TO MAKING ANY DECISION WITH RESPECT TO THE OFFERS.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

        This section describes certain United States federal income tax consequences of the tender of the Debentures pursuant to the Offers. It applies to you only if you hold the Debentures as capital assets for tax purposes. The following discussion is not exhaustive of all possible tax considerations and does not address any alternative minimum tax consequences.

        This section does not apply to you if you are a member of a class of holders subject to special rules, such as:

•

a dealer in securities,



•

a trader in securities that elects to use a mark-to-market method of accounting for your securities holdings,



•

a bank,



•

a life insurance company,



•

a tax-exempt organization,



•

a United States expatriate,



•

a person that owns Debentures that are a hedge or that are hedged against interest rate risks,



•

a person that owns Debentures as part of a straddle or conversion transaction for tax purposes, or



•

a United States holder (as defined below) whose functional currency for tax purposes is not the U.S. dollar.

        This section is based on the Internal Revenue Code of 1986, as amended (the "Code"), its legislative history, existing and proposed regulations under the Internal Revenue Code, published rulings and court decisions, all as currently in effect. These laws are subject to change, possibly on a retroactive basis.

        If a partnership tenders the Debentures, the United States federal income tax treatment of a partner will generally depend on the status of the partner and the tax treatment of the partnership. A partner in a partnership holding the Debentures should consult its tax advisor with regard to the United States federal income tax treatment of a tender of Debentures pursuant to this Offer.

        You are a United States holder (a "U.S. Holder") if you are a beneficial owner of Debentures and you are:

•

an individual citizen or resident of the United States,



•

a domestic corporation,



•

an estate whose income is subject to United States federal income tax regardless of its source, or



•

a trust if (i) a United States court can exercise primary supervision over the trust's administration and one or more United States persons are authorized to control all substantial decisions of the trust or (ii) the trust has a valid election in effect under applicable Treasury regulations to be treated as a United States person.

        You are a non-United States holder (a "Non-U.S. Holder") if you are a beneficial owner of Debentures that is an individual, corporation, estate or trust that is not a U.S. Holder.

Tender of Debentures Pursuant to the Offers

Consequences to U.S. Holders

        A U.S. Holder who receives cash for Debentures pursuant to the Offers will recognize gain or loss equal to the difference between (i) the amount of cash received (less any amounts attributable to accrued and unpaid interest, which will be included in income as interest income for U.S. federal income tax purposes to the extent not previously included) and (ii) the U.S. Holder's adjusted tax basis in the Debentures. A U.S. Holder's adjusted tax basis in a Debenture generally will be the cost of the Debenture to such U.S. Holder, (a) increased by any original issue discount ("OID") previously included in income, and market discount (if any) included in income with respect to the Debenture pursuant to an election to include market discount in gross income currently as it accrues, and (b) decreased (but not below zero) by any amortizable bond premium (generally, the excess, if any, of the tax basis of the Debenture to a U.S. Holder immediately after its acquisition over the principal amount of the Debenture payable at maturity) which the U.S. Holder has previously deducted. Except as discussed below with respect to market discount, such gain or loss generally will be capital gain or loss and will be long-term capital gain or loss if the Debenture has been held for more than one year. Net long-term capital gain recognized by an individual U.S. Holder generally is subject to tax at a maximum rate of 15%. The ability of U.S. Holders to deduct capital losses is subject to limitations under the Code.

        A U.S. Holder who acquired a Debenture at a "market discount" (subject to a statutorily-defined de minimis exception) generally will be required to treat any gain on the tender thereof pursuant to the Offers as ordinary income rather than capital gain to the extent of the accrued market discount, unless an election was made to include market discount in income as it accrued for U.S. federal income tax purposes. Market discount at the time a Debenture is purchased generally equals the excess of the adjusted issue price of the Debenture over a U.S. Holder's initial tax basis in the Debenture.

Consequences to Non-U.S. Holders

        Any gain realized by a Non-U.S. Holder on the receipt of cash for Debentures generally will not be subject to U.S. federal income or withholding tax unless (i) such gain is effectively connected with the conduct of a trade or business in the United States by such Non-U.S. Holder (and, if certain tax treaties apply, is attributable to a U.S. permanent establishment maintained by such Non-U.S. Holder), (ii) in the case of an individual Non-U.S. Holder, such Non-U.S. Holder is present in the United States for 183 days or more in the taxable year of the Offers and certain other conditions are met or (iii) the Debentures constitute a "U.S. real property interest" within the meaning of the Foreign Investment in Real Property Tax Act ("FIRPTA").

        If the Debentures are treated as U.S. real property interests any gain you recognize upon the sale or other disposition of the Debentures will be subject to net income tax in the United States under FIRPTA, and the purchaser would be required to withhold and pay to the IRS ten percent of the amount paid in exchange for the Debentures in respect of such tax. As a general matter, your Debentures should not constitute U.S. real property interests so long as the Company is a domestically-controlled REIT, defined generally as a REIT less than fifty percent in value of whose stock is and was held directly or indirectly by foreign persons at all times during a specified testing period. The Company believes that it is and will continue to be a domestically-controlled REIT and, therefore, that FIRPTA will not apply to a sale or other disposition of the Debentures. Accordingly, the Company does not intend to withhold FIRPTA taxes from amounts payable upon tender of the Debentures. Even if the Company does not qualify as a domestically-controlled REIT, your Debentures generally will not constitute U.S. real property interests unless (1) on the date you acquire your Debentures your Debentures have a fair market value greater than five percent of the Company's common stock or (2) if the Debentures are "regularly traded" on an "established securities market" within the meaning

23

---

Table of Contents

of applicable Treasury regulations, at any time during the five-year period ending on the date you dispose of your Debentures, you owned more than five percent of the total fair market value of the outstanding Debentures. It is not clear whether the Company's common shares owned by you or ownership of both 2027 Debentures and 2026 Debentures will affect the calculation of the percentages described above. You are urged to consult your own tax advisor as to whether you will be subject to tax under FIRPTA upon a disposition of your Debentures.

        Any amounts paid to a Non-U.S. Holder that are attributable to accrued and unpaid interest or OID on the Debentures generally will not be subject to U.S. federal withholding tax, provided (i) the Non-U.S. Holder does not own, actually or constructively, 10 percent or more of the total combined voting power of all classes of the Company's voting stock; (ii) the Non-U.S. Holder is not, for U.S. federal income tax purposes, a controlled foreign corporation related, directly or indirectly, to the Company through stock ownership; and (iii) certain certification requirements (summarized below) are met (the "portfolio interest exemption"). If a Non-U.S. Holder does not qualify for the portfolio interest exemption, any amounts attributable to accrued and unpaid interest or OID generally will be subject to U.S. federal withholding tax at a 30% rate (or such lower rate provided by an applicable treaty), unless such amounts are effectively connected with the conduct of a trade or business in the United States by such Non-U.S. Holder (and, if certain tax treaties apply, are attributable to a U.S. permanent establishment maintained by such Non-U.S. Holder).

        If gain on the receipt of cash for Debentures and amounts attributable to any accrued and unpaid interest or OID on the Debentures are effectively connected with the conduct of a trade or business in the United States by a Non-U.S. Holder (and, if certain tax treaties apply, are attributable to a U.S. permanent establishment maintained by the Non-U.S. Holder), the Non-U.S. Holder will be exempt from U.S. withholding tax (provided the Non-U.S. Holder complies with the certification procedures described in the following paragraph) but will be subject to regular U.S. federal income tax on such amounts in the manner described above with respect to U.S. Holders. In addition, if the Non-U.S. Holder is a foreign corporation, it may be subject to a branch profits tax equal to 30% (or such lower rate provided by an applicable treaty) of its effectively connected earnings and profits for the taxable year, subject to certain adjustments.

        In order for amounts attributable to accrued and unpaid interest or OID on the Debentures to qualify for the portfolio interest exemption or, as the case may be, the exception from U.S. withholding tax for income effectively connected with the conduct of a trade or business in the United States, one of the following requirements must be met at the time payment is made: (i) the withholding agent holds a valid Form W-8BEN or Form W-8ECI, as the case may be, from the Non-U.S. Holder and can reliably associate the payment with the Form W-8BEN or W-8ECI, or (ii) the Non-U.S. Holder holds the Debentures through certain qualified foreign intermediaries and satisfies the certification requirements of applicable Treasury regulations.

Information Reporting and Backup Withholding

        In general, in the case of a U.S. Holder, other than certain exempt Holders, the Company and other payors are required to report to the IRS the gross proceeds from the tender of the Debentures pursuant to the Offers. Additionally, backup withholding generally will apply to payments of gross proceeds from the tender of the Debentures pursuant to the Offers if a U.S. Holder that is not otherwise exempt from backup withholding (i) fails to provide an accurate taxpayer identification number and certify that the taxpayer identification number is correct, (ii) fails to certify that it is not subject to backup withholding, or (iii) otherwise fails to comply with applicable backup withholding rules. If applicable, backup withholding will be imposed at a rate of 28%.

        In the case of a Non-U.S. Holder, information returns will be filed with the IRS in connection with the payment of accrued interest or OID on the Debentures. Backup withholding and additional

24

---

Table of Contents

information reporting will not apply to payments made to a Non-U.S. Holder pursuant to the Offers if the Non-U.S. Holder provides the required certification that it is not a U.S. person, or the Non-U.S. Holder otherwise establishes an exemption, provided that the payor or withholding agent does not have actual knowledge or reason to know that the Holder is a U.S. person or that the conditions of any exemption are not satisfied.

        In addition, payments of the proceeds from the tender of a Debenture by a Non-U.S. Holder to or through a foreign office of a broker or the foreign office of a custodian, nominee, or other dealer acting on behalf of a Non-U.S. Holder generally will not be subject to information reporting or backup withholding. However, if the broker, custodian, nominee, or other dealer is a U.S. person, a controlled foreign corporation for U.S. federal income tax purposes, a foreign partnership that is either engaged in a trade or business within the United States or whose U.S. partners in the aggregate hold more than 50% of the income or capital interest in the partnership, a foreign person 50% or more of whose gross income for a certain period is effectively connected with a trade or business within the United States, or a U.S. branch of a foreign bank or insurance company, information reporting (but not backup withholding) generally will be required with respect to payments made to a Non-U.S. Holder unless the broker, custodian, nominee, or other dealer has documentation of the Non-U.S. Holder's foreign status and the broker, custodian, nominee, or other dealer has no actual knowledge or reason to know to the contrary, or the Non-U.S. Holder otherwise establishes an exemption from information reporting.

        Payment of the proceeds from the tender of a Debenture by a Non-U.S. Holder to or through the U.S. office of a broker is subject to information reporting and backup withholding, unless the Non-U.S. Holder certifies as to its non-U.S. person status (and the broker does not have actual knowledge or reason to know to the contrary) or the Non-U.S. Holder otherwise establishes an exemption from information reporting and backup withholding.

        Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against a Holder's U.S. federal income tax liability, provided the required information is timely furnished to the IRS.
