(c) Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and exchange of beneficial interests in the Global Notes will be effected through the Depository, in accordance with the provisions of the Indenture and the Applicable Procedures. Transfers of beneficial interests in the Global Notes will require compliance with either subparagraph (1) or (2) below, as applicable, as well as one or more of the other following subparagraphs, as applicable:

(1) Transfer of Beneficial Interests in the Same Global Note. Beneficial interests in any Global Note may be transferred to persons who take delivery thereof in the form of a beneficial interest in a Global Note. No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in this Section 3.2(c)(1).

13

(2) All Other Transfers of Beneficial Interests in Global Notes. In connection with all transfers of beneficial interests that are not subject to Section 3.2(c)(1) above, the transferor of such beneficial interest must deliver to the Registrar both:

(i) a written order from a Participant or an Indirect Participant given to the Depository in accordance with the Applicable Procedures directing the Depository to credit or cause to be credited a beneficial interest in another Global Note in an amount equal to the beneficial interest to be transferred or exchanged; and

(ii) instructions given in accordance with the Applicable Procedures containing information regarding the Participant account to be credited with such increase.

Upon satisfaction of all of the requirements for transfer or exchange of beneficial interests in Global Notes contained in the Indenture and the Notes or otherwise applicable under the Securities Act, the Trustee shall adjust the principal amount of the relevant Global Note(s) pursuant to Section 3.2(g) hereof.

(d) Transfer and Exchange of Beneficial Interests in Global Notes for Definitive Notes. If any holder of a beneficial interest in a Global Note proposes to exchange such beneficial interest for a Definitive Note or to transfer such beneficial interest to a person who takes delivery thereof in the form of a Definitive Note pursuant to Section 3.2(a), then, upon satisfaction of the conditions set forth in Section 3.2(c)(2) hereof, the Trustee will cause the aggregate principal amount of the applicable Global Note to be reduced accordingly pursuant to Section 3.2(g) hereof, and the Company will execute and the Trustee will authenticate and deliver to the person designated in the instructions a Definitive Note in the appropriate principal amount. Any Definitive Note issued in exchange for a beneficial interest pursuant to this Section 3.2(d) will be registered in such name or names and in such authorized denomination or denominations as the holder of such beneficial interest requests through instructions to the Registrar from or through the Depository and the Participant or Indirect Participant. The Trustee will deliver such Definitive Notes to the persons in whose names such Notes are so registered.

(e) Transfer and Exchange of Definitive Notes for Beneficial Interests in Global Notes. A Holder of a Definitive Note may exchange such Note for a beneficial interest in a Global Note or transfer such Definitive Notes to a person who takes delivery thereof in the form of a beneficial interest in a Global Note at any time. Upon receipt of a request for such an exchange or transfer, the Trustee will cancel the applicable Definitive Note and increase or cause to be increased the aggregate principal amount of one of the Global Notes.

If any such exchange or transfer from a Definitive Note to a beneficial interest is effected pursuant to the previous paragraph at a time when a Global Note has not yet been issued, the Company will issue and, upon receipt of a Company Order, the Trustee will authenticate one or more Global Notes in an aggregate principal amount equal to the principal amount of Definitive Notes so transferred.

14

(f) Transfer and Exchange of Definitive Notes for Definitive Notes. Upon request by a Holder of Definitive Notes and such Holder’s compliance with the provisions of this Section 3.2(f), the Registrar will register the transfer or exchange of Definitive Notes. Prior to such registration of transfer or exchange, the requesting Holder will present or surrender to the Registrar the Definitive Notes duly endorsed or accompanied by a written instruction of transfer in form satisfactory to the Registrar duly executed by such Holder or by his attorney, duly authorized in writing. A Holder of Definitive Notes may transfer such Notes to a person who takes delivery thereof in the form of a Definitive Note. Upon receipt of a request to register such a transfer, the Registrar shall register the Definitive Notes pursuant to the instructions from the Holder thereof.

(g) Cancellation and/or Adjustment of Global Notes. At such time as all beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note will be returned to or retained and canceled by the Trustee in accordance with Section 2.12 of the Base Indenture. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a person who will take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented by such Global Note will be reduced accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depository at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a person who will take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note will be increased accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depository at the direction of the Trustee to reflect such increase.

ARTICLE IV.

REDEMPTION OF NOTES

The provisions of Article III of the Base Indenture, as amended by the provisions of this Fourth Supplemental Indenture, shall apply to the Notes.

Section 4.1 Optional Redemption of Notes.

(a) The Company shall have the right to redeem the Notes at its option and in its sole discretion at any time or from time to time prior to the Par Call Date, in whole or in part. The redemption price (“Redemption Price”) will equal the greater of (i) 100% of the principal amount of the Notes to be redeemed and (ii) as determined by the Quotation Agent, the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed that would be due if the Notes matured on the Par Call Date (not including any portion of such payments of interest accrued as of the Redemption Date) discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate plus 40 basis points (0.40% or forty-hundredths of one percent), plus, in each case, accrued and unpaid interest thereon to, but not including, the Redemption Date; provided, however, that if the Redemption Date falls after a Record Date and on or prior to the corresponding Interest Payment Date, the Company will pay the full amount of accrued and unpaid interest, if any, on such Interest Payment Date to the Holder of record at the close of business on the corresponding Record Date (instead of the Holder surrendering its Notes for redemption). Notwithstanding the foregoing, if the Notes are redeemed on or after the Par Call Date, the Redemption Price will be equal to 100% of the principal amount of the Notes being redeemed plus unpaid interest, if any, accrued thereon to, but excluding, the Redemption Date.

(b) The Company shall not redeem the Notes pursuant to Section 4.1(a) hereof on any date if the principal amount of the Notes has been accelerated, and such an acceleration has not been rescinded or cured on or prior to such date (except in the case of an acceleration resulting from a default by the Company in the payment of the Redemption Price with respect to the Notes to be redeemed).

17

(c) Any redemption and notice of redemption may, at the Company’s discretion, be subject to the satisfaction of one or more conditions precedent.

Section 4.2 Notice of Optional Redemption, Selection of Notes.

(a) In case the Company shall desire to exercise the right to redeem all or, as the case may be, any part of the Notes pursuant to this Section 4.2, it shall fix a date for redemption and it or, at its written request received by the Trustee not fewer than five (5) Business Days prior (or such shorter period of time as may be acceptable to the Trustee) to the date the notice of redemption is to be mailed (or sent by electronic transmission), the Trustee in the name of and at the expense of the Company, shall mail (or send by electronic transmission) or cause to be mailed (or sent by electronic transmission) a notice of such redemption not fewer than fifteen (15) calendar days nor more than sixty (60) calendar days prior to the Redemption Date to each Holder of Notes so to be redeemed in whole or in part at its last address as the same appears on the Note Register; provided, that if the Company makes such request of the Trustee, it shall, together with such request, also give written notice of the Redemption Date to the Trustee; provided further that the text of the notice shall be prepared by the Company. Such mailing shall be by first class mail (unless sent by electronic transmission). The notice, if mailed in the manner herein provided, shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice. In any case, failure to give such notice by mail or any defect in the notice to the Holder of any Note designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Note.

(b) Each such notice of redemption shall specify: (i) the aggregate principal amount of Notes to be redeemed, (ii) the CUSIP number or numbers, if any, of the Notes being redeemed, (iii) the Redemption Date (which shall be a Business Day), (iv) the Redemption Price at which Notes are to be redeemed, (v) the place or places of payment and that payment will be made upon presentation and surrender of such Notes and (vi) that interest accrued and unpaid to, but excluding, the Redemption Date will be paid as specified in said notice, and that on and after said date interest thereon or on the portion thereof to be redeemed will cease to accrue, and if such redemption is subject to the satisfaction of one or more conditions precedent, such notice shall state that, in the Company’s discretion, the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the Redemption Date, or by the Redemption Date so delayed. If fewer than all the Notes are to be redeemed, the notice of redemption shall identify the Notes to be redeemed (including CUSIP numbers, if any). In case any Note is to be redeemed in part only, the notice of redemption shall state the portion of the principal amount thereof to be redeemed and shall state that, on and after the Redemption Date, upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion thereof will be issued.

(c) Whenever any Notes are to be redeemed, the Company will give the Trustee written notice of the Redemption Date, together with an Officers’ Certificate as to the aggregate principal amount of Notes to be redeemed not fewer than twenty (20) calendar days (or such shorter period of time as may be acceptable to the Trustee) prior to the Redemption Date.

18

(d) Subject to the satisfaction of any conditions of a conditional redemption, on or prior to the Redemption Date specified in the notice of redemption given as provided in this Section 4.2, the Company will deposit with the Paying Agent an amount of monies in immediately available funds sufficient to redeem on the Redemption Date all the Notes (or portions thereof) so called for redemption at the appropriate Redemption Price; provided, that if such payment is made on the Redemption Date, it must be received by the Paying Agent, by 11:00 a.m., New York City time, on such date. The Company shall be entitled to retain any interest, yield or gain on amounts deposited with the Paying Agent pursuant to this Section 4.2(d) in excess of amounts required hereunder to pay the Redemption Price (it being acknowledged that the Trustee have no obligation to invest any such deposit).

(e) If less than all of the outstanding Notes are to be redeemed, the Trustee shall select the Notes or portions thereof of the Global Note or the Notes in certificated form to be redeemed (in principal amounts of $2,000 and integral multiples of $1,000 in excess thereof), on a pro rata basis, by lot, or such other method the Trustee deems fair and appropriate or is required by the Depository; provided that so long as the notes are represented by one or more Global Notes, interests in such Global Notes shall be selected for redemption by the Depository in accordance with its standard procedures therefor. The Notes (or portions thereof) so selected for redemption shall be deemed duly selected for redemption for all purposes hereof.

Section 4.3 Payment of Notes Called for Redemption by the Company.

(a) If notice of redemption has been given as provided in Section 4.2 hereof, and subject to the satisfaction of any conditions of a conditional redemption, the Notes or portion of Notes with respect to which such notice has been given shall become due and payable on the Redemption Date and at the place or places stated in such notice at the Redemption Price, and unless the Company shall default in the payment of such Notes at the Redemption Price, so long as Paying Agent holds funds sufficient to pay the Redemption Price of the Notes to be redeemed on the Redemption Date, then (a) such Notes will cease to be outstanding on and after the Redemption Date, (b) interest on the Notes or portion of Notes so called for redemption shall cease to accrue on and after the Redemption Date and (c) the Holders of the Notes shall have no right in respect of such Notes except the right to receive the Redemption Price thereof. On presentation and surrender of such Notes at a place of payment in said notice specified, the said Notes or the specified portions thereof shall be paid and redeemed by the Company at the Redemption Price, together with interest accrued thereon to, but excluding, the Redemption Date; provided, however, if the Redemption Date falls after a Record Date and on or prior to the corresponding Interest Payment Date, the Company will pay the full amount of accrued and unpaid interest and premium, if any, due on such Interest Payment Date to the Holder of record at the close of business on the corresponding Record Date.

19

(b) Upon presentation of any Note redeemed in part only, the Company shall execute and the Trustee shall authenticate and make available for delivery to the Holder thereof, at the expense of the Company, a new Note or Notes, of authorized denominations, in principal amount equal to the unredeemed portion of the Notes so presented.

Section 5.1 Note Guarantee.

By its execution hereof, the Guarantor acknowledges and agrees that the Notes shall be entitled to the benefits of a Guarantee. Accordingly, subject to the provisions of this Article, the Guarantor hereby unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee, the Trustee, and its successors and assigns that: (i) the principal of (including the Redemption Price upon redemption pursuant to Article IV), premium, if any, and interest, if any, on the Notes shall be duly and punctually paid in full when due, whether at the Stated Maturity, upon acceleration, upon redemption or otherwise, and interest on overdue principal, premium, if any, and (to the extent permitted by law) interest on any interest, if any, on the Notes and all other obligations of the Company to the Holders or the Trustee hereunder or under the Notes (including fees, expenses or other) shall be promptly paid in full or performed, all in accordance with the terms hereof; and (ii) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, the same shall be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at the Stated Maturity, by acceleration, call for redemption or otherwise, subject, however, in the case of clauses (i) and (ii) above, to the limitations set forth in this Article (collectively, the “Guarantee Obligations”).

Subject to the provisions of this Article, the Guarantor hereby agrees that its Guarantee hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any thereof, the entry of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of the Guarantor. The Guarantor hereby waives and relinquishes: (a) any right to require the Trustee, the Holders or the Company (each, a “Benefited Party”) to proceed against the Company or any other person or to proceed against or exhaust any security held by a Benefited Party at any time or to pursue any other remedy in any secured party’s power before proceeding against the Guarantor; (b) any defense that may arise by reason of the incapacity, lack of authority, death or disability of any other person or persons or the failure of a Benefited Party to file or enforce a claim against the estate (in administration, bankruptcy or any other proceeding) of any other person or persons; (c) diligence, presentment, benefit of discussion, demand, protest and notice of any kind (except as expressly required by the Indenture), including but not limited to notice of the existence, creation or incurring of any new or additional indebtedness or obligation or of any action or non-action on the part of the

The Guarantor hereby covenants that, except as otherwise provided therein, the Guarantee shall not be discharged except by payment in full of all Guarantee Obligations, including the principal, premium, if any, and interest on the Notes and all other costs provided for under the Indenture.

If any Holder or the Trustee is required by any court or otherwise to return to either the Company or the Guarantor, or any trustee or similar official acting in relation to either the Company or the Guarantor, any amount paid by the Company or the Guarantor to the Trustee or such Holder, the Note Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. The Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any Guarantee Obligations hereby until payment in full of all such obligations guaranteed hereby. The Guarantor agrees that, as between it, on the one hand, and the Holders of Notes and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article VI of the Base Indenture for the purposes hereof, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guarantee Obligations, and (y) in the event of any acceleration of such obligations as provided in Article VI of the Base Indenture, such Guarantee Obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantor for the purpose of the Guarantee.

Section 5.2 Execution and Delivery of Note Guarantee.

(a) To evidence the Guarantee set forth in Section 5.1 hereof, the Guarantor agrees that a Notation of Guarantee substantially in the form included in Exhibit B hereto shall be endorsed on each Note authenticated and delivered by the Trustee and that this Fourth Supplemental Indenture shall be executed on behalf of the Guarantor by an Officer of the Guarantor.

(b) The Guarantor agrees that the Guarantee set forth in this Article V shall remain in full force and effect and apply to all the Notes notwithstanding any failure to endorse on each Note a notation of the Guarantee.

(c) If an Officer whose facsimile signature is on a Note or a notation of Guarantee no longer holds that office at the time the Trustee authenticates the Note on which the Guarantee is endorsed, the Guarantee shall be valid nevertheless.

21

(d) The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Guarantee set forth in this Fourth Supplemental Indenture on behalf of the Guarantor.

Section 5.3 Limitation of Guarantor’s Liability; Certain Bankruptcy Events.

(a) The Guarantor, and by its acceptance hereof each Holder, hereby confirms that it is the intention of all such parties that the Guarantee Obligations of the Guarantor pursuant to its Note Guarantee not constitute a fraudulent transfer or conveyance for purposes of any Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law. To effectuate the foregoing intention, the Holders and the Guarantor hereby irrevocably agree that the Guarantee Obligations of the Guarantor under this Article V shall be limited to the maximum amount as shall, after giving effect to all other contingent and fixed liabilities of the Guarantor, result in the Guarantee Obligations of the Guarantor under the Note Guarantee not constituting a fraudulent transfer or conveyance.

(b) The Guarantor hereby covenants and agrees, to the fullest extent that it may do so under applicable law, that in the event of the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Company, the Guarantor shall not file (or join in any filing of), or otherwise seek to participate in the filing of, any motion or request seeking to stay or to prohibit (even temporarily) execution on the Note Guarantee and hereby waives and agrees not to take the benefit of any such stay of execution, whether under Section 362 or 105 of the Bankruptcy Law or otherwise.

Section 5.4 Application of Certain Terms and Provisions to the Guarantor.

(a) For purposes of any provision of the Indenture which provides for the delivery by the Guarantor of an Officers’ Certificate and/or an Opinion of Counsel, the definitions of such terms in Section 1.1 of the Base Indenture shall apply to the Guarantor as if references therein to the Company or the Guarantor, as applicable, were references to the Guarantor.

(b) Any notice or demand which by any provision of the Indenture is required or permitted to be given or served by the Trustee or by the Holders of Notes to or on the Guarantor may be given or served as described in Section 10.2 of the Base Indenture as if references therein to the Company were references to the Guarantor.

(c) Upon any demand, request or application by the Guarantor to the Trustee to take any action under the Indenture, the Guarantor shall furnish to the Trustee such certificates and opinions as are required in Section 15.1 of this Fourth Supplemental Indenture as if all references therein to the Company were references to the Guarantor.

22

ARTICLE VI.

ADDITIONAL COVENANTS

The following additional covenants shall apply with respect to the Notes so long as any of the Notes remain outstanding:

Section 6.1 Maintenance of Office or Agency.

The Company will maintain an office or agency in the United States where the Notes may be surrendered for registration of transfer or exchange or for presentation for payment or redemption and where notices and demands to or upon the Company in respect of the Notes and the Indenture may be served. As of the date of the Indenture, such office shall be the Corporate Trust Office and, at any other time, at such other address as the Trustee may designate from time to time by notice to the Company. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency not designated or appointed by the Trustee. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office. Notwithstanding the foregoing, the Corporate Trust Office shall not be a place for service of legal process on the Company.

The Company may also from time to time designate co-registrars and one or more offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

The Company hereby initially designates the Trustee as Paying Agent, Registrar and the Corporate Trust Office shall be considered as one such office or agency of the Company for each of the aforesaid purposes.

Section 6.2 Appointments to Fill Vacancies in Trustee’s Office.

The Company, whenever necessary to avoid or fill a vacancy in the office of Trustee, will appoint, upon the terms and conditions and otherwise as provided in Section 7.8 of the Base Indenture, a Trustee, so that there shall at all times be a Trustee hereunder.

Section 6.3 Reports.

The Company and the Guarantor will:

(a) file with or deliver to the Trustee, within fifteen (15) days after the Company or the Guarantor files them with the Commission, copies of the annual reports and information, documents and other reports which the Company or the Guarantor may be required to file with the Commission pursuant to Section 13 or Section 15(d) of the Exchange Act; or, if the Company or the Guarantor is not required to file information, documents or reports pursuant to those Sections, then the Company and the Guarantor will file with or deliver to the Trustee and the Commission, in accordance with rules and regulations prescribed from time to time by the Commission, such of the supplementary and periodic information, documents and reports which Section 13 of the Exchange Act may require with respect to a security listed and registered on a national securities exchange, and within the time periods otherwise required by the rules and regulations of the SEC; and

23

(b) file with or deliver to the Trustee and the Commission, in accordance with the rules and regulations prescribed from time to time by the Commission, such additional information, documents and reports with respect to compliance by the Company and the Guarantor with the conditions and covenants of the indenture as may be required from time to time by such rules and regulations.

Notwithstanding the foregoing, if permitted by the SEC, the Company may satisfy its obligation to furnish the reports described above by furnishing such reports filed by the Guarantor. Reports, information and documents filed with the Commission via the EDGAR system will be deemed to be delivered to the Trustee as of the time of such filing via EDGAR for purposes of this covenant; provided, however, that the Trustee shall have no obligation whatsoever to determine whether or not such information, documents or reports have been filed via EDGAR. Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including its compliance with any of its covenants relating to the notes (as to which the Trustee is entitled to rely exclusively on an Officers’ Certificate).

Section 6.4 Limitations on Incurrence of Debt.

(a) The Company will not, and will not permit any of its Subsidiaries to, incur any Debt (including, without limitation, Acquired Debt) if, immediately after giving effect to the incurrence of such Debt and the application of the proceeds from such Debt on a pro forma basis, the aggregate principal amount of all of the Company’s and its Subsidiaries’ outstanding Debt (determined on a consolidated basis in accordance with GAAP) is greater than 60% of the sum of the following (without duplication): (1) the Company’s and its Subsidiaries’ Total Assets as of the last day of the then most recently ended fiscal quarter for which financial information is available and (2) the aggregate purchase price of any real estate assets or mortgages receivable acquired, and the aggregate amount of any securities offering proceeds and Debt proceeds received (to the extent such proceeds were not used to acquire real estate assets or mortgages receivable or used to reduce Debt), by the Company or any Subsidiary since the end of such fiscal quarter, including the proceeds obtained from the incurrence of such additional Debt.

(b) The Company will not, and will not permit any of its Subsidiaries to, incur any Debt (including, without limitation, Acquired Debt) secured by any Lien on any of the Company’s or any of its Subsidiaries’ property or assets, whether owned on the date of the indenture or subsequently acquired, if, immediately after giving effect to the incurrence of such Debt and the application of the proceeds from such Debt on a pro forma basis, the aggregate principal amount (determined on a consolidated basis in accordance with GAAP) of all of the Company’s and its Subsidiaries’ outstanding Debt which is secured by a Lien on any of the Company’s and its Subsidiaries’ property or assets is greater than 40% of the sum of (without duplication): (1) the Company’s and its Subsidiaries’ Total Assets as of the last day of the then most recently ended fiscal quarter for which financial information is available; and (2) the aggregate purchase price of any real estate assets or mortgages receivable acquired, and the aggregate amount of any securities offering proceeds and Debt proceeds received (to the extent such proceeds were not used to acquire real estate assets or mortgages receivable or used to reduce Debt), by the Company or any of its Subsidiaries since the end of such fiscal quarter, including the proceeds obtained from the incurrence of such additional Debt.

(c) The Company will not, and will not permit any of its Subsidiaries to, incur any Debt (including without limitation Acquired Debt) if the ratio of Consolidated Income Available for Debt Service to Annual Debt Service Charge for the period consisting of the four consecutive fiscal quarters most recently ended prior to the date on which such additional Debt is to be incurred shall have been less than 1.5:1 on a pro forma basis after giving effect to the incurrence of such Debt and the application of the proceeds from such Debt (determined on a consolidated basis in accordance with GAAP), and calculated on the following assumptions:

(i) such Debt and any other Debt (including, without limitation, Acquired Debt) incurred by the Company or any of its Subsidiaries since the first day of such four-quarter period had been incurred, and the application of the proceeds from such Debt (including to repay or retire other Debt) had occurred, on the first day of such period;

(ii) the repayment or retirement of any other Debt of the Company or any of its Subsidiaries since the first day of such four-quarter period had occurred on the first day of such period (except that, in making this computation, the amount of Debt under any revolving credit facility, line of credit or similar facility will be computed based upon the average daily balance of such Debt during such period); and

(iii) in the case of any acquisition or disposition or the placement of any assets in service or removal of any assets from service by Company or any of its Subsidiaries of any asset or group of assets with a fair market value in excess of $1.0 million since the first day of such four-quarter period, whether by merger, stock purchase or sale or asset purchase or sale or otherwise, such acquisition, disposition, placement in service or removal from service had occurred as of the first day of such period with the appropriate adjustments with respect to such acquisition or disposition being included in such pro forma calculation.

If the Debt giving rise to the need to make the calculation described in this Section 6.4(c) or any other Debt incurred after the first day of the relevant four-quarter period bears interest at a floating rate, then, for purposes of calculating the Annual Debt Service Charge, the interest rate on such Debt will be computed on a pro forma basis by applying the average daily rate which would have been in effect during the entire four-quarter period to the greater of the amount of such Debt outstanding at the end of such period or the average amount of such Debt outstanding during such period. For purposes of this Section 6.4(c), Debt will be deemed to be incurred by the Company or any of its Subsidiaries whenever the Company or such Subsidiary shall create, assume, guarantee or otherwise become liable in respect thereof.

25

(d) The Company will not have at any time Total Unencumbered Assets of less than 150% of the aggregate principal amount of all of the Company’s and its Subsidiaries’ outstanding Unsecured Debt determined on a consolidated basis in accordance with GAAP.

Section 6.5 Insurance.

The Company will, and will cause each of its Subsidiaries to, keep in force upon all of the Company’s and each of its Subsidiaries’ properties and operations insurance policies carried with responsible companies in such amounts and covering all such risks as is customary in the industry in which the Company and its Subsidiaries do business in accordance with prevailing market conditions and availability.

Section 6.6 Maintenance of Properties.

The Company will cause all of its properties used or useful in the conduct of the business of the Company or any of its Subsidiaries to be maintained and kept in good condition, repair and working order, normal wear and tear, casualty and condemnation excepted, and supplied with all necessary equipment and the Company will cause all necessary repairs, renewals, replacements, betterments and improvements to be made, all as in the Company’s judgment may be necessary in order for the Company to at all times properly and advantageously conduct its business carried on in connection with such properties. The Company and the Guarantor will not be prevented from (1) removing permanently any property that has been condemned or suffered a casualty loss, if it is in their best interests, (2) discontinuing maintenance or operation of any property if, in the Guarantor’s reasonable judgment, such removal is in the best interest of the Guarantor and is not disadvantageous in any material respect to the holders of the notes, or (3) selling or otherwise disposing for value its properties in the ordinary course of business consistent with the terms of the Indenture.

Section 6.7 Payment of Taxes and Other Claims.

The Company and the Guarantor will each pay or discharge or cause to be paid or discharged before it becomes delinquent: (i) all material taxes, assessments and governmental charges levied or imposed on the Company, the Guarantor or any of their respective Subsidiaries or on their respective or any such Subsidiary’s income, profits or property; and (ii) all material lawful claims for labor, materials and supplies that, if unpaid, might by law become a Lien upon their respective property or the property of any of their respective Subsidiaries; provided, however, that neither the Company nor the Guarantor will be required to pay or discharge or cause to be paid or discharged any tax, assessment, charge or claim the amount, applicability or validity of which is being contested in good faith.

Section 6.8 Existence.

Subject to Article VII hereof, each of the Company and the Guarantor will do or cause to be done all things necessary to preserve and keep in full force and effect its (i) existence, and (ii) rights (charter and statutory) and franchises; provided, that neither the Company nor the Guarantor shall be required to preserve any such right or franchise if the Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company or the Guarantor, as applicable.
